Drying filter and its combined structure of drying and filtering

Abstract

The invention discloses a dry filter and its combined structure for drying and filtering. The combined structure for drying and filtering comprises: an inner cylinder part (1) capable of passing through a filtered fluid, and the inner cylinder part (1) has a granular molecular sieve (7); end stoppers (2) capable of passing filtered fluid, the end stoppers (2) being arranged at both ends of the inner cylinder part (1). The dry filter combination structure provided by the present invention avoids the process of making the filter element, and only needs to complete the proportioning process before assembly, which reduces a series of problems such as filter element adjustment and manufacturing process, multi-state part specifications, and process error-proof control. Reduce the difficulty of processing; solve the problem of powder drop, particle drop and cracking of the filter element, avoid the short circuit of the filter fluid, ensure the filtration performance, avoid the problem of the structure deflection of the dry filter combination, and ensure the dry filter combination during use The balance of structural circulation and ability to filter impurities improves the service life.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a drying filter and its combined structure for drying and filtering. Background technique [0002] Dry filter products are mostly two-way dry filters, which are mainly suitable for circuits with two-way flow requirements in heat pump systems. The interior of the dry filter is designed with a combination of drying and filtration to absorb moisture and residual acid in the refrigerant, and filter the refrigeration system. Impurities in the pipeline will lock the impurities inside the dry filter, thus ensuring the system to operate in the best condition. [0003] Such as Figure 1-5 As shown, the dry filter includes a dry filter combined structure (the combined structure of the dry filter core 01 and the filter plate 02), a body 6, a one-way valve part 8, an end cover 9 and a connecting pipe, which are arranged symmetrically as a whole, so that the filtered fluid (refrigera...

AI Technical Summary

Problems solved by technology

When the filtered fluid flows in from the inlet, flows along the channel between the dry filter element 01 and the body 6, and flows out directly after passing through the filter sheet 02 of soft material, forming a short circuit, affecting the drying and filtering functions, and the product has a short service life , leading to high system cost

Moreover, the assembly of the filter sheet 01 on both sides of the dry filter combined structure has no positioning, resulting in a deflection of the assembly, which affects the balance of the flow rate and filtered impurities during the use of the product, and shortens the service life of the product
