In hot weather, what problems should be paid attention to in the coal conveying system?

In high temperature weather, dust accumulation is easy to produce fire hazards, it is recommended to install dust-proof devices, and the following analysis is made on the dust-proof devices on the market for your reference:

In industrial production, solid materials are easy to produce a large amount of dust in the process of conveying, and the dust reduction device can realize the dust reduction of the conveyed materials.

The dust reduction device on the existing belt conveying device is usually a spray device is added at the conveying process or at the outlet, and the water flow is sprayed into the dust removal space with mist particles, and the dust pollution is reduced by using the mode of water mist dust reduction. This method requires a large amount of water resources.

There is also a kind of adding dust bags on the belt conveyor, in the body, dust collection port, air outlet, flower plate and a plurality of filter bags connected with the flower plate and evenly distributed, the dust falls back to the coal conveying belt after being filtered by the filter bag, thereby reducing the dust pollution of the coal conveying belt, but this needs to be matched with a fan, and the filter bag needs to be maintained and replaced regularly, under normal circumstances, the number of filter bags used on a coal conveying belt is numerous, and the replacement is frequent and the daily maintenance cost is very high.

In addition to the above two kinds of dust-proof devices, Shenyu Electric has a national patent that integrates energy saving, environmental protection and low operating costs in one of the coal conveying belt conveyor dust reduction device - all-inclusive lifting coal conveyor dust cover. The dust cover unit is more than 95% dustproof, and it is easy to clean and easy to replace or repair the roller parts. The coal-fired power plant is equipped with a dust cover for the coal conveying belt, which not only solves the dust pollution and noise pollution of the belt conveyor caused by the lignite belt transportation of the coal-fired power plant, but also greatly reduces the fire hazard at the coal conveying site.

"Eight precautions" to deal with hot days.

First, we should pay attention to taking effective protective measures when working outdoors, avoid being naked in the sun for a long time**, and it is best to bring cold drinks;

Second, be careful not to walk in the sun, and do not go to places where people gather. After returning from outside to indoors, do not turn on the air conditioner immediately;

Third, try to avoid traveling between 10 a.m. and 4 p.m., and drink water before you are thirsty;

Fourth, we should pay attention to dietary hygiene on high temperature days to prevent gastrointestinal colds;

Fifth, we should pay attention to maintaining sufficient sleep, living and working regularly, and enhancing immunity;

Sixth, we should pay attention to the care of special groups, especially the elderly and children, who are prone to induce cardiovascular and cerebrovascular diseases and adverse symptoms in children on high temperature days;

Seventh, we should pay attention to prevent the onset of solar dermatitis after sun exposure. If there are symptoms such as redness and swelling, it should be rinsed with cool water, and severe cases should go to the hospital**;

8. Pay attention to dizziness, nausea, dry mouth, confusion, chest tightness and shortness of breath and other symptoms, should be suspected to be an early symptom of heat stroke, should immediately rest, drink some cold water to cool down, serious condition should immediately go to the hospital**.

Don't put flammable and explosive materials in the car! Stop and don't put the front of your car in the sun! Don't leave children in the car, etc.!

Hot climates generally refer to summer. Summer is characterized by long days and short nights, high temperatures, and more thundershowers. There are many disadvantages to driving in such conditions:

1. It is easy to produce the "boiling" of the water tank, the gas resistance of the fuel system, the "water loss" of the battery, the failure of the hydraulic brake due to the gas resistance, and the bursting of tires.

2. Due to the lack of sleep at night and the high temperature of the cab, the driver is easy to be tired and doze off, and is prone to heat stroke, which is not conducive to safe driving.

3. At night, there are many people enjoying the shade on both sides of the roads near the towns and villages along the city streets and highways, and there are many children chasing and playing, and there are many people rushing to the cool in the morning and evening.

4. The weather is changeable, there are many typhoons, and there are many thunderstorms, which sometimes often catch people off guard, causing traffic accidents or disorder.

5. The residue road is oily and melted, which increases the driving resistance, increases the tread temperature, and is easy to slide in case of rain.

2. Precautions for operation.

1. According to the needs of travel, carry necessary buckets, rainproof canvas, non-slip chains and other supplies, and it is best to bring heatstroke prevention medicines for use on the way.

2. Pay attention to prevent the engine from overheating while driving. The water temperature gauge should indicate the reading at any time, generally not more than 95 degrees Celsius, if the temperature is too high, choose a cool place to stop and cool down, and can lift the hood to ventilate and dissipate heat. To maintain the amount of cooling water, be careful to prevent the cooling water from boiling and burning your hands and face.

3. When the fuel system is blocked, it should be stopped to cool down, then disassemble the carburetor inlet pipe joint, pull the rocker arm of the oil pump to fill the gasoline pipe, remove the air, and cover the upper shell of the gasoline pump with a wet cloth and cotton yarn to insulate and cool down to reduce the occurrence of gas resistance. It is better to be able to install an electric oil pump or try to produce the phenomenon of gasoline. It is best to install a fuel pump or try to insulate the heat between the gasoline pump and the exhaust pipe.

4. When the tire temperature and tire pressure are too high, you should choose a cool place to stop and let it return to normal naturally.

Brief and concise: pay attention to heatstroke prevention, sun protection, this is the key haha 1, do not expose yourself to the sun, bring some cold drinks.

2. Don't walk around in crowded places, let alone blow the air conditioner directly under the sweat 3. Try not to travel before 10 am to 4 pm.

4. Pay attention to food hygiene if it is too hot.

5. Maintain adequate sleep and live a regular life.

6. Dizziness, retching, nausea, dry mouth, etc. are early symptoms of heat stroke, you should rest immediately, drink some cold water to cool down, and send to the hospital in time if the situation is serious.

1. If the engine water temperature is too high, antifreeze should be added. The engine water temperature is too high mostly due to the lack of antifreeze, the vehicle should be parked in a cool place to cool down, do not turn off, let the engine continue to idle running, open the machine cover to dissipate heat, when the temperature drops down and then add antifreeze to the water tank, do not pour cold water on the engine, which may cause the engine block to burst and cannot be repaired. Some car owners simply use tap water instead of antifreeze, which is a wrong practice, because there are many impurities in the water, which are easy to leave sediment in the engine, water tank, etc., so they cannot replace antifreeze with water.

2. Check the heat dissipation system and clean the radiator in time. You should also check whether the "thermostat" is working properly, and never remove the "thermostat". Because the "thermostat" is a switch that controls the size and circulation of coolant, the engine working temperature can be kept in an optimal range, so that the engine will work with the strongest power, the most wear, the lowest fuel consumption, if it is removed, it will cause parts to wear, and the low water temperature will lead to a decrease in power and an increase in fuel consumption.

3. Clean the water tank and condenser. The water tank and condenser are important components of the vehicle cooling system and air conditioning, with the long-term use of the vehicle, such as dust, sediment, catkins, etc., will be mixed in the gap between the two, which will affect the water temperature and air conditioning and refrigeration performance.

What should I pay attention to when exercising in high temperatures?

There is a saying about the weather that "cold is in Sanjiu and hot is in the middle of the volt", and now it has just entered the middle volt, and this year's mid-volt is 20 days, so the hot weather will last for about three weeks. If you come across"Autumn fool"Then it's going to be hot for a month.

Lasts until autumn.

Wait, vicious heat.

At least half a month later, it cooled down a little, and the temperature during the eleventh day was also around 37.

It's time to weaken into August, and the hottest time is coming to an end.

Cause Analysis:

1 Because after the beginning of autumn, according to the experience of previous years, there will be a short-term phenomenon of high temperatures for a period of time, which is called autumn tiger. It usually occurs at the turn of August and September and lasts about 7-15 days. After that, the weather began to get cooler in the morning and evening than in July.

2 This year's beginning of autumn will fall on August 7, 2020, which is the 18th day of the sixth month of the lunar calendar. According to the general situation, the number of tigers in autumn lasts about 7-15 days. Therefore, it is expected that the 2020 "Autumn Tiger" will end after August 14-22.

The hot weather may continue for another month or so.

Because according to the traditional Chinese lunar calendar, after the beginning of autumn (August 8), there will be 24 "autumn tigers", only after the summer (August 23), the temperature will slowly drop, generally as long as the beginning of September, it is difficult to have a high temperature of more than 35 degrees.

I don't understand, maybe it's after the summer solstice, I don't understand.
