Anonymous users2024-02-111.The size of the filter bag.
The diameter of the outer filter round filter bag is 114-200mm, and the length is 2-9m, and the commonly used specifications are 120-160mm in diameter and 2-6m in length.
The diameter of the inner filter round filter bag is generally 130-300mm, and the length is 1800-12000mm.
Flat filter bags are mostly external filters, with specifications of 1000mm*2000mm, and larger ones can reach 2000mm*2000mm.
The standardization of filter bag specifications is very important for the rational application of filter material (no waste or less waste of scrap material) and processing work and automated production, but the design of filter bags is often based on process requirements and many varieties, commonly used specifications are as follows:
2.Deviation of the size of the filter bag.
1) Deviation of the size of the circular filter bag As mentioned above, for the circular filter bag, the difference between the measured value (p 2) and the nominal value (p 0 2) of the inner diameter is taken as the deviation of the half circumference of the round filter bag. The provisions of the national standard on the deviation of the half-circumference of the original filter bag of different specifications are shown in the table. However, in practical application, the outer filter round bag is not allowed to have negative deviation due to the bag cage installed in the middle, and attention should be paid to the design and processing.
The half-circumference deviation of the circular filter bag is measured as follows.
The upper mouth and the lower mouth of the filter bag are measured once, and the semicircular length p 2 of the filter bag is measured every other time in the middle
Calculate the nominal semicircular length of the filter bag p0 2;
The half-circumference deviation of the circular filter bag is a.
The length specifications and limit deviations of the round filter bags are shown in the table. However, due to the size requirements of the outer filter type circular middle-mounted bag cage, this bag should not have a negative deviation.
Because of the external filter filter bag, because the filter bag should be installed on the drawing board, and the bag cage is put in the middle, the filter bag mouth and the flower board, Danlong have more stringent size requirements, and the limit deviation is smaller.
2) Size deviation of flat filter bag For flat filter bag to determine its specifications according to its perimeter, the limit deviation of its inner perimeter and length is based on the alkali table.

2.The number of square meters per bag.
3.Number of square meters of cloth bag * fabric ** square meters.
Summary: The general calculation of the filter bag is based on the number of square meters required for the filter material *** filter bag = **.

Anonymous users2024-02-09What is the budget for the cost of making filter cloth into filter bags? .The filter bag of the centrifuge should be the same as that of the centrifuge. "mesh" represents the size of the filter cloth in terms of filter cloth, and the larger the number of meshes, the smaller the cloth eye; Filter cloth.

Anonymous users2024-02-08The unit price calculation company of the filter bag is as follows:
Unit price = filter bag area x area unit price + labor cost.
Filter bag area = ( x pattern plate hole size + feeding) x length.
Area unit price = according to the material of different models.
Manual cost = depending on the material and length, as well as the level of complexity.

Anonymous users2024-02-05Hello, the filtration area of the bag filter is calculated according to the diameter and length of the bag cage.
Polyester filter bag (PE filter bag) is made of polyester fiber filter cloth, pure fiber is made of needle punching, forming a three-dimensional, highly fluffy three-dimensional depth, tortuous filter layer. It is characterized by loose fibrous tissue, which increases the capacity of impurities; The product is a compound interception mode, which effectively removes solid and soft particles, that is, larger particles and impurities are trapped on the surface of the fiber, and fine particles are caught in the deep layer of the filter material to ensure that they will not be damaged due to increased pressure during use, and have high filtration efficiency.
Nylon filter bag industry standard monofilament mesh material has stable and reliable pores, specializing in filtering hard particles. The widely used material is nylon. The three grades of Nylon Mesh Bags are specially designed for the paint and ink sector, capturing free silicone and grease with its unique treatment process. >>>More

The dust collector bag cage is a cylinder surrounded by a metal grid, and the two ends of the cylinder are open to communicate with the air duct. The dust collector bag cage uses the airflow pressure generated by the fan to press the dust-containing air to the surface of the dust collector bag cage, and most of the short linter and impurities are trapped on the surface of the dust collector bag cage. A filter fiber mesh layer is formed, and at the same time, the dust-laden air through the dust collector bag cage enters the second stage filter device through the channels on both sides of the dust collector bag cage. >>>More
