Description

Technical Field

[0001] This utility model relates to the field of filters, and more specifically, to a high-efficiency filter assembly that discharges residual liquid. Background Technology

[0002] A filter is a device or equipment used to separate, screen, or purify substances. It uses specific filter media, such as filter screens, filter membranes, and filter cartridges, to block or retain larger particles, impurities, and suspended solids, while allowing smaller particles or fluids to pass through.

[0003] Publication No. CN118615768A discloses a filter capable of discharging residual filtrate and its usage method. This invention filters most of the filtrate through an upper filter element. The filtered filtrate enters the upper filter chamber, flows from the central pipe into the drain pipe, then through the central pipe into branch pipe A, and finally gathers in the outer collecting pipe before being discharged through drain pipe A. Next, compressed gas is introduced from the top of the filter tank through the air inlet pipe to pressurize the residual filtrate inside, causing it to be filtered again through the upper filter element before being discharged. If residual filtrate remains inside the tank, pressure is applied to the drain pipe of the sleeve, filtering the residual filtrate through the lower filter element. After filtration, the filtrate flows through the sleeve into the second drain pipe, which then flows into branch pipe B. After gathering in the inner collecting pipe, the filtrate passes through the side pipe and is finally discharged through drain pipe B.

[0004] Although the aforementioned invention connects the upper and lower chambers of the filter element through two independent pipes to control the discharge of filtrate from the upper and lower parts separately, ultimately achieving the purpose of removing residual liquid, the upper and lower chambers of the filter element are both drained by a central pipe and a sleeve located inside the filter element. Moreover, the sleeve is placed inside the central pipe, which severely restricts the liquid flow space between the two pipes, resulting in poor drainage efficiency. At the same time, this nested design of the central pipe and the sleeve, located inside the filter element, requires more precise processes during production to ensure the dimensional accuracy and installation position accuracy of each component due to the small assembly space between them, which is not conducive to production. Furthermore, during use, the presence of these two pipes and their relative positional relationship may cause the filter element to be subjected to uneven forces in the vertical direction, affecting the verticality of the filter element and ultimately affecting its filtration effect.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a high-efficiency filter assembly that discharges residual liquid. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-efficiency filter component that can discharge residual liquid.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency filtration assembly that discharges residual liquid, comprising a filter element and a pipe structure connected to the filter element, wherein the filter element comprises a filter cavity formed by multiple filter cylinders arranged in a circumferential array, and the filter cylinders are separated by a partition to form upper and lower chambers;

[0008] The pipeline structure includes two independent pipes, namely drain pipe A and drain pipe B. Drain pipe A is connected to the upper filter chamber of the filter element, and drain pipe B is connected to the lower filter chamber of the filter element through a central pipe.

[0009] Preferably, the drain pipe B is welded to the outer wall of the drain pipe A, the central pipe is located in the inner center of the filter element, its end extends through the partition to the lower filter chamber of the filter element, its top extends out from the head of the filter element and through the drain pipe A to the drain pipe B, and its contact with the drain pipe A and the partition is sealed.

[0010] Preferably, an annular fixing plate that fits into the filter cartridge is welded to the outer wall of the partition, and the two sets of filter cartridges separated by the partition are connected by the annular fixing plate.

[0011] Preferably, end caps are installed at both the upper and lower ends of the filter cartridge to improve the stability of the filter element connection.

[0012] Preferably, the drain pipe A is semi-cylindrical, and its notch portion fits into the outer wall of the drain pipe A, thus saving material.

[0013] Preferably, a reverse air intake assembly is also installed on the pipeline connecting the drain pipe A and the drain pipe B to ensure the stability and reliability of the filtration effect.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model eliminates the sleeve design and directly connects the upper chamber to the drain pipe A located outside the filter element, which greatly increases the liquid passage space of the two pipes and improves the drainage efficiency. Moreover, designing a drain pipe directly outside the filter element increases the assembly space between them, making it easier to manufacture. Furthermore, the filter element has only one central tube, which can effectively avoid the filter element being subjected to uneven forces in the vertical direction, thereby improving the verticality and structural strength of the filter element. This overcomes the shortcomings of the sleeve-related structure and solves the problems in the background technology.

[0016] 2. This utility model can tightly fit the inner wall of the filter cartridge through the annular fixing plate, and can limit the position of multiple filter cartridges, making the connection more reliable.

[0017] 3. A reverse air intake component is also installed on the pipeline connecting the drain pipe A and the drain pipe B of this utility model to remove the material on the filter cloth on the filter element, prevent residual material from affecting the subsequent filtration process, ensure the stability and reliability of the filtration effect, and improve product quality.

[0018] 4. The drain pipe A of this utility model is semi-cylindrical, and its notch is fitted with the outer wall of the drain pipe A, so that the drain pipe A and the drain pipe B can share a side wall, which can effectively save materials. Attached Figure Description

[0026] like Figure 1-4 As shown, this utility model provides a high-efficiency filter assembly that discharges residual liquid, including a filter element 1 and a pipe structure 2 connected to the filter element 1. The filter element 1 includes a filter cavity formed by multiple filter cylinders 101 arranged in a circumferential array, and the filter cylinders 101 are separated by a partition 102 to form upper and lower chambers. Both the upper and lower ends of the filter cylinders 101 are equipped with end caps 104.

[0027] The pipeline structure 2 includes two independent pipelines, namely drain pipe A201 and drain pipe B202. Drain pipe A201 is connected to the upper filter chamber of filter element 1, and drain pipe B202 is connected to the lower filter chamber of filter element 1 through central pipe 203. Specifically, drain pipe B202 is welded to the outer wall of drain pipe A201. Central pipe 203 is located in the inner center of filter element 1. Its end extends through partition 102 into the lower filter chamber of filter element 1, and its top extends from the head of filter element 1, through drain pipe A201, and into drain pipe B202. The contact parts of B202 with drain pipe A201 and partition 102 are sealed together.

[0028] It should be noted that the partition 102 blocks the filter element 1 into two chambers, forming two sets of filter cartridges 101. Filter cloth is provided on the surface of both sets of filter cartridges 101.

[0029] During normal use, pressure is applied to the drain pipe A201, causing the liquid filtered by the upper filter cartridge 101 and entering the upper chamber to be directly drawn into the drain pipe A201 located outside the filter element 1 (filtered by the filter cloth on the surface of the filter cartridge 101, not shown in the figure), and then discharged. Afterwards, compressed gas is injected to drain any remaining liquid. If liquid still accumulates at the bottom of the filtration tank using this method... By applying pressure to the drain pipe B202, the residual liquid is filtered through the lower filter cartridge 101 and enters the lower chamber. Then, it is drawn into the drain pipe B202 through the central pipe 203 and subsequently discharged, thus achieving the purpose of removing residual liquid. This eliminates the need for a sleeve design and connects the upper chamber directly to the drain pipe A201 located outside the filter element 1, greatly increasing the liquid passage space between the two pipes and improving the drainage efficiency. Moreover, designing a drain pipe directly outside the filter element increases the assembly space between them, making production easier. At the same time, the presence of only one central pipe 203 in the filter element 1 effectively avoids uneven forces on the filter element 1 in the vertical direction, thereby improving the verticality and structural strength of the filter element 1.

[0030] In summary, compared with the existing filter components, the filter element of this invention has better verticality and higher structural strength. At the same time, the components are easier to manufacture and the drainage efficiency is also greatly improved.

[0031] Furthermore, an annular fixing plate 103 is welded to the outer wall of the partition 102 to fit the filter cartridge 101. The annular fixing plate 103 connects the two sets of filter cartridges 101 separated by the partition 102. It should be noted that the annular fixing plate 103 is designed to fit the filter cartridge 101, can fit tightly to the inner wall of the filter cartridge 101, and can limit the position of multiple filter cartridges 101, making the connection more reliable. In addition, a reverse air intake component is installed on the pipeline connecting the drain pipe A201 and the drain pipe B202 to remove the material on the filter cloth on the filter element 1, prevent residual material from affecting the subsequent filtration process, ensure the stability and reliability of the filtration effect, and improve product quality.

[0032] Meanwhile, the drain pipe A201 of this utility model is semi-cylindrical, and its notch is in close contact with the outer wall of the drain pipe A201, so that the drain pipe A201 and the drain pipe B202 can share a side wall, which can effectively save materials.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
