Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a clean room filter. Background Art

[0002] Cleanroom air filters are primarily used in laboratories involved in research in microbiology, biomedicine, biochemistry, animal experiments, genetic recombination, and biological products, collectively referred to as clean laboratories and biosafety laboratories. A search revealed Chinese Patent Publication No. CN214862041U, which discloses a novel cleanroom HEPA filter. The filter comprises a housing, a water tank fixedly connected to the interior of the housing, a fan fixedly connected to the top of the water tank, an air distribution mechanism plugged into the interior of the housing, a housing cover, and an air inlet baffle fixedly connected to one side of the housing. The advantages of the present invention are as follows: by setting up a collection box, when moisture in the air condenses on the surface of the air balancing plate, the drainage plate will drain the water droplets condensed on the surface of the air balancing plate into the collection box for storage, and release them through the residual valve, thereby avoiding the rusting of parts due to the condensation of water droplets inside the box, and at the same time extending the service life of the equipment; by setting the water inlet on the outside of the equipment, when it is necessary to add water to the water tank, the block is unscrewed and water is injected into the water tank through the water pipe set on one side of the box, which is easy to operate and highly practical. However, when the filter is cleaning the inside, the cleaning device is set inside the filter. Although the dust scraped off can be absorbed by the suction pipe, there will still be a lot of dust attached to the scraper that cannot be cleaned. After a long period of accumulation, the scraper cannot be used and the filter cannot be cleaned. At the same time, a strange smell will appear inside the filter, resulting in a reduced efficiency of the cleaning device. Utility Model Content

[0003] In response to the deficiencies in the prior art, the utility model provides a clean room filter, which solves the problem that when the filter is cleaned internally, a cleaning device is arranged inside the filter. Although the dust scraped off can be absorbed by the suction pipe, most of the dust attached to the scraper cannot be cleaned. After a long period of accumulation, the scraper cannot be used and the filter cannot be cleaned. At the same time, an odor appears inside the filter, which reduces the efficiency of the cleaning device.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a clean room filter, including a filter box and a water tank, the right end of the filter box is fixedly installed with an air inlet pipe, and the upper end is fixedly installed with an air outlet pipe, the upper and lower ends of the inner side walls of the filter box are respectively rotatably connected with a first roller and a second roller, the first roller and the second roller are wrapped with a filter screen, and the filter screen is arranged between the air inlet pipe and the air outlet pipe, the inner side wall of the filter box is fixedly installed with a scraper, the side wall of the scraper and the side wall of the filter screen are in contact with each other, and the rear end of the filter box is fixedly installed with a rotating motor, and the output shaft of the rotating motor is fixedly connected to one end of the first roller by passing through the interior of the filter box.

[0005] Preferably, a baffle is fixedly installed on the bottom surface of the filter box, a water trough is provided between the baffle and the right side wall of the filter box, the baffle is provided on the left side wall of the filter screen, and the top surface of the baffle is higher than the top surface of the scraper, so that the scraped dust is stored in the water.

[0006] Preferably, a connecting port is provided inside the front end side wall of the filter box, and a filter plate is slidably connected to the inside of the connecting port. The filter plate is connected to the inside of the filter box by passing through the inside of the connecting port and fits tightly with the side wall inside the filter box, thereby enhancing the filtering of the incoming particles.

[0007] Preferably, the right side wall and the front side wall of the filter box are respectively fixedly connected with a water injection pipe and a drainage pipe, and both are connected to the interior of the water tank. Valves are fixedly installed inside the water injection pipe and the drainage pipe, so as to facilitate water injection and drainage into the filter box.

[0008] Preferably, a plurality of anti-skid particles are fixedly installed on the side walls of the first roller and the second roller at equal intervals, thereby increasing the friction between the first roller and the second roller and the filter screen, thereby driving the filter screen to rotate.

[0009] Preferably, the front and rear side walls of the filter screen are in contact with the inner side walls of the filter box, thereby being able to completely filter the incoming gas.

[0010] The utility model provides a clean room filter with the following beneficial effects:

[0011] 1. When using the clean room filter, the filter screen is wound around the first roller and the second roller, so that the dust attached to the filter screen can be easily moved and scraped into the water by the scraper;

[0012] 2. When using the clean room filter, the dust in the water can be conveniently and centrally thrown out through the provided water tank and drain pipe, and the amount of dust adhering to the scraper can also be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of anti-slip particles 12 are fixedly installed on the side walls of the first roller 9 and the second roller 10 at equal intervals. The front and rear side walls of the filter screen 8 fit with the inner side walls of the filter box 1, and air is introduced into the interior of the filter box 1 through the air inlet pipe 2, and the wind needs to pass through the inside of the filter screen 8. The filter screen 8 can filter the dust in the wind. At the same time, the rotating motor 7 is turned on to rotate the first roller 9 and the filter screen 8, so that the scraper 11 can scrape off the dust on the filter screen 8.

[0021] Example 2

[0022] In this embodiment, Figure 1-4 As shown, a baffle 15 is fixedly installed on the bottom surface of the filter box 1, and a water trough 13 is provided between the baffle 15 and the right side wall of the filter box 1. The baffle 15 is provided on the left side wall of the filter screen 8, and the top surface of the baffle 15 is higher than the top surface of the scraper 11. The right side wall and the front end side wall of the filter box 1 are respectively fixedly connected with a water injection pipe 4 and a drainage pipe 5, and both are connected to the interior of the water trough 13. Valves 16 are fixedly installed inside the water injection pipe 4 and the drainage pipe 5. Water is injected into the water trough 13 through the water injection pipe 4. The surface of the water cannot be higher than the top surface of the baffle 13, so that the scraper 11 can completely store the dust scraped off the filter screen 8 in the water.

[0023] It should be noted that, in this embodiment, when using a clean room filter, Figure 1-4As shown, first, open the valve 16 on the water injection pipe 4 and fill water into the water tank 13 in the filter box 1. The surface of the water cannot be higher than the top surface of the baffle 13. Then close the valve 16. When the filter box 1 is working, air is introduced into the filter box 1 through the air inlet pipe 2.
