Description

Technical Field

[0001] The utility model belongs to the field of filters, and in particular relates to a PE microporous filter. Background Art

[0002] In recent years, with the rapid improvement of the national economic level, product quality has become an important factor affecting the comprehensive competitiveness of enterprises.

[0003] Baking soda is a chemical raw material that has received widespread attention in recent years. With its increasingly wide application areas, quality indicators have become an important factor in promoting the development of related companies, especially for the production quality of baking soda used in the food industry. To fully ensure that the quality of baking soda meets relevant industry standards, the alkali solution in the baking soda must be fully filtered.

[0004] However, these filters have the following problems during use:

[0005] The turbidity of the alkali solution filtered by mechanical filters and closed filter presses is too high to meet the requirements of fine processing and cannot be used. Plate and frame filter presses filter turbid liquid. Although the quality of the turbid liquid after filtering has improved after repeated selection of filter cloth, the filtration speed is slow. In a very short time, the fine mud blocks the filter cloth holes and is forced to unload the mud. Since the filter plates are not filled with filter cakes, a large part of the alkali solution is discharged every time the mud is unloaded, resulting in serious losses and waste. In addition, the filter mud sticks to the filter cloth, and it needs to be repeatedly rinsed with water before unloading, and the material is fed again. The effective operation time is short, and the production is very uneconomical.

[0006] Therefore, we propose a PE microporous filter to solve the above problems. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. In the utility model, alkali liquid enters the coarse filtration chamber through the liquid inlet pipe. When the alkali liquid passes through the filter tube, fine mud and some organic particles adhere to the outer wall of the filter tube, and the liquid penetrates into the filter tube through the coarse filtration holes on the filter tube and flows into the filter box.
