Description

Technical Field

[0001] This utility model relates to the filtration of adhesive liquids, and in particular to a filter element and a filter for adhesive liquids. Background Technology

[0002] The original adhesive filter screen used stainless steel mesh. Due to the high viscosity and high delivery pressure of the adhesive, ordinary stainless steel mesh is prone to breakage under high pressure, which enters the adhesive dispensing system and causes wear on the delivery pump and pipeline unit. In addition, the adhesive tends to stick to the filter screen and is not easy to clean. Utility Model Content

[0004] The objective of this utility model is achieved through the following technical solution: A filter element includes an outer frame, an inner frame, and a sandwiched filter cartridge. The sandwiched filter cartridge is located between the outer frame and the inner frame. Both the outer frame and the inner frame have a plurality of mesh openings. On a horizontal projection plane, the sandwiched filter cartridge is a corrugated closed cylinder, with the crests of the sandwiched filter cartridge fixedly connected to the inner side of the outer frame, and the troughs of the sandwiched filter cartridge fixedly connected to the outer side of the outer frame. The crests of the sandwiched filter cartridge are welded to the inner side of the outer frame, and the troughs of the sandwiched filter cartridge are welded to the outer side of the outer frame.

A filter element holder is located at the inlet end of the outlet pipe, and a filter element is mounted on the holder. The inlet of the outlet pipe communicates with the inner cavity of the filter element. A filter element cover is located at the top of the filter element, and a lower sleeve ring is located at the bottom. The lower sleeve ring is sealed to the inlet end of the outlet pipe and contacts the filter element holder. A lower adhesive connector is located at the bottom of the filter element, and an upper adhesive connector is located at the top. An outer frame, an inner frame, and a jacketed filter cartridge are located between the upper and lower adhesive connectors. A lower annular groove is formed on the lower sleeve ring, and an upper annular groove is formed on the top of the filter element cover. The lower adhesive connector is bonded to the lower annular groove, and the upper adhesive connector is bonded to the upper annular groove. An annular sealing groove is formed on the inner wall of the lower sleeve ring, and an annular sealing ring is located within the groove.

[0006] The present invention has the following advantages: the filter for adhesive liquid of the present invention has a filter area that is 3-4 times larger than that of ordinary cylindrical filter elements, which reduces the flow resistance of the filter element, improves the filtration efficiency, has a larger dirt holding capacity, and a longer filter element cleaning cycle.

[0017] As shown in Figure 1, a filter for adhesive includes a tank 1 with a removable lid 7 on the top. In this embodiment, the tank 1 and the lid 7 are connected by a flange, and a sealing ring is also provided between them. The tank 1 has an inlet pipe 3 and an outlet pipe 4, and the connectors of the inlet pipe 3 and the outlet pipe 4 are also equipped with flanges for easy connection to pipelines. The inlet pipe 3 communicates with the cavity 8 of the tank 1, and the adhesive enters the cavity 8 of the tank 1 through the inlet pipe 3. In this embodiment, a filter element seat 5 is provided at the inlet end of the outlet pipe 4, and a filter element 2 is installed on the filter element seat 5. The inlet of the outlet pipe 4 communicates with the inner cavity of the filter element 2. A filter element cover 6 is provided on the top of the filter element 2, and a lower sleeve ring 9 is provided at the bottom of the filter element 2. The lower sleeve ring 9 is sealed and installed on the outlet pipe 4. The inlet end is connected to the filter element seat 5, and the lower sleeve 9 contacts the filter element seat 5. After the glue is filtered by the filter element 2, the filtered glue is discharged from the outlet pipe 4. In this embodiment, the filter element 2 includes an outer frame 21, an inner frame 22, and a sandwich filter cylinder 23. The sandwich filter cylinder 23 is located between the outer frame 21 and the inner frame 22. Both the outer frame 21 and the inner frame 22 have several mesh holes. In this embodiment, the outer frame 21 and the inner frame 22 are made by punching holes in stainless steel plates and then welding them in a circular shape. They have high structural strength and are not easily damaged. On the horizontal projection plane, the sandwich filter cylinder 23 is a corrugated closed cylinder. Therefore, the filtration area of ​​the sandwich filter cylinder 23 is 3-4 times larger than that of a cylindrical filter, thereby reducing the flow resistance of the filter element 2, improving the filtration efficiency, and increasing the dirt holding capacity. The cleaning cycle is longer. In this embodiment, the sandwich filter screen uses a stainless steel laser-perforated filter screen. During manufacturing, a stainless steel laser-perforated plate is used, and then the stainless steel laser-perforated plate is folded into a corrugated shape. Moreover, the sandwich filter screen using a stainless steel laser-perforated filter screen has high strength, high filtration efficiency, low flow resistance, and high surface smoothness of the laser-perforated plate, making it difficult for adhesive and contaminant particles in the adhesive to adhere, which is convenient for cleaning and backwashing. The crest of the sandwich filter cylinder 23 is fixedly connected to the inner side of the outer frame 21, and the trough of the sandwich filter cylinder 23 is fixedly connected to the outer side of the outer frame 21. Furthermore, the crest of the sandwich filter cylinder 23 is welded to the inner side of the outer frame 21, and the trough of the sandwich filter cylinder 23 is welded to the outer side of the outer frame 21, thereby ensuring the stability of the sandwich filter cylinder 23 installation, so that the entire filter element 2 has high structural strength. Under the high pressure of adhesive filtration, it is difficult for the wire to break, thereby ensuring the reliability of the drug dispensing system.

[0018] In this embodiment, a lower adhesive joint 24 is provided at the bottom of the filter element 2, and an upper adhesive joint 25 is provided at the top of the filter element 2. The outer frame 21, inner frame 22, and sandwich filter cylinder 23 are located between the upper adhesive joint 25 and the lower adhesive joint 24. The upper adhesive joint 25 and the lower adhesive joint 24 further improve the structural strength of the filter element 2. Furthermore, a lower annular groove is provided on the lower sleeve 9, and an upper annular groove is provided on the top of the filter element cover 6. The lower adhesive joint 24 is bonded in the lower annular groove, and the upper adhesive joint 25 is bonded in the upper annular groove, thereby facilitating the installation of the filter element 2 with the filter element cover 6 and the lower sleeve 9. In this embodiment, an annular sealing groove is provided on the inner sidewall of the lower sleeve 9, and an annular sealing ring is provided in the annular sealing groove, thereby ensuring the sealing performance between the lower sleeve 9 and the water outlet end of the liquid outlet pipe 4 and preventing leakage between the lower sleeve 9 and the liquid outlet pipe 4.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that...

[0020] Modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
