Detailed Implementation

[0022] This utility model discloses a commercial washable air filter. The following description, in conjunction with a preferred embodiment (Example 1), is shown in the accompanying drawings. Figures 1 to 8 The specific embodiments of this utility model will be further described below.

[0023] See attached diagram. Figures 1 to 8 , Figures 1 to 4 Commercial washable air filters are shown from different perspectives. Figures 5 to 8 The partial structures of commercial washable air filters are shown.

[0024] Example 1.

[0025] Preferably, the commercial washable air filter includes a tank assembly 100, which includes an upper tank 101 and a lower tank 102 integrally formed with the upper tank 101, such that the upper tank 101 and the lower tank 102 together form an inner cavity 103 for containing filtrate (not shown in the figure). The commercial washable air filter also includes a reflux assembly 200, wherein:

[0026] The tank assembly 100 also includes an air inlet pipe 110 and a liquid inlet 120. The air inlet pipe 110 is inserted into the upper tank 101 and extends to the bottom of the lower tank 102. The liquid inlet 120 is integrally formed with the upper tank 101. The upper tank 101 is provided with a sealing mechanism 130. This allows the air to be filtered (i.e., air intake) to be introduced into the filter liquid in the inner cavity 103 through the air inlet pipe 110. On the other hand, when it is not necessary to inject filter liquid into the upper tank 101 (i.e., no liquid injection is required), the sealing mechanism 130 closes the liquid inlet 120 to prevent the filter liquid from overflowing from the liquid inlet 120 during air injection. Furthermore, while the filter liquid is injected into the upper tank 101 through the liquid inlet 120, the filtered air can also be collected simultaneously through the liquid inlet 120 (i.e., air collection), which means that liquid injection and air collection are carried out simultaneously.

[0027] The reflux assembly 200 includes a reflux pipe 210, a first gate valve 220, a second gate valve 230, and a third gate valve 240. One end of the reflux pipe 210 is connected to the upper tank 101, and the other end is connected to the lower tank 102. The first gate valve 220 is located between the reflux pipe 210 and the upper tank 101 and is connected to the reflux pipe 210. The second gate valve 230 is located between the reflux pipe 210 and the lower tank 102 and is connected to the reflux pipe 210. The third gate valve 240 is located between the first gate valve 220 and the lower tank 102. The first gate valve 220 is connected to the second gate valve 230 and the third gate valve 240 is connected to the return pipe 210. When the first gate valve 220 and the second gate valve 230 are open and the third gate valve 240 is closed, the filtrate in the upper tank 101 can flow back into the lower tank 101 from the first gate valve 220 into the return pipe 210. When the first gate valve 220 and the third gate valve 240 are open and the second gate valve 230 is closed, the filtrate (upper layer liquid) in the upper tank 101 flows from the first gate valve 220 into the return pipe 210 and then flows out from the third gate valve 240.

[0028] It should be noted that by opening the second gate valve 230 and the third gate valve 240 and closing the first gate valve 220, the filtrate (lower layer liquid) located in the lower tank 102 can enter the return pipe 210 from the second gate valve 230 and then flow out from the third gate valve 240. This can be used to empty the inner cavity 103 and facilitate subsequent processes such as water washing and cleaning of the inner cavity 103.

[0029] The sealing mechanism 130 includes a sealing port 131, which has two symmetrical sealing port ears 132. The sealing port ears 132 are integrally formed with the sealing port 131, and the sealing port 131 is detachably connected to the injection port 120. This facilitates closing or opening the sealing port 131.

[0030] The commercial washable air filter also includes a positioning frame 300, which includes a positioning plate 310 and two positioning brackets 320. One end of the positioning bracket 320 is fixedly connected to the positioning plate 310, and the other end of the positioning bracket 320 is fixedly connected to the upper tank 101.

[0031] The positioning plate 310 has a positioning hole 311, which is directly opposite the air inlet pipe 110 and the liquid injection port 120, facilitating liquid injection and air intake operations.

[0032] The commercial washable air filter also includes two frames 400. Each frame 400 includes a support frame 410 and an arc-shaped support plate 420. The arc-shaped support plate 420 is distributed along the outer periphery of the lower tank 102 and is fixedly connected to the lower tank 102. The support frame 410 is fixedly connected to the arc-shaped support plate 420 for stable support.

[0033] It is worth mentioning that the specific components and other technical features of the filtrate involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0034] For those skilled in the art, 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.
