Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, and more specifically to a hand-cranked filter cleaning structure. Background Art

[0002] Water treatment is a necessary step before all kinds of water use, whether it is drinking water or agricultural and industrial water. Water treatment is required to filter out the mud and dirt in the water. Existing filters mostly use a filter screen structure, and each time they are cleaned and maintained, they must be shut down and disassembled for cleaning, which wastes manpower and material resources, increases equipment maintenance costs, and can also reduce the service life of water treatment equipment.

[0003] The existing patent is a hand-cranked cleaning filter. The patent authorization number is CN207913325U. A brush is set in the filter screen of the filter, and a crank and a drain valve are set at both ends of the filter. The crank can be manually cranked at any time to rotate the brush to clean the sand and dirt in the filter screen, and the drain valve is opened to discharge it. The utility model has a simple structure, low cost, labor, and time saving, reduces maintenance costs, and extends the service life of the filter. The utility model can be promoted and applied to water treatment mesh filters.

[0004] However, patent authorization number CN207913325U adopts a method of setting a brush inside the filter screen, and setting a crank and a drain valve at both ends of the filter. The crank can be manually turned at any time to rotate the brush to clean the sand and dirt in the filter screen. Since too frequent cleaning will greatly waste manpower, in order to be able to identify whether the filter screen inside the filter needs to be cleaned and save manpower, we have proposed a hand-cranked filter cleaning structure to solve the above-mentioned problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a hand-cranked filter cleaning structure, which can observe that the pressure values ​​of the pressure gauges installed at the water inlet pipe and the water outlet pipe are inconsistent, indicating that the filter cartridge needs to be cleaned. By manually holding the crank and turning it, the bristles will clean the impurities attached to the surface of the filter cartridge, and the stop valve at the drain pipe will be opened to discharge the cleaned impurities from the inside of the shell. It can identify whether the filter screen inside the filter needs to be cleaned, thus saving manpower.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] (1) In this scheme, when the attachments on the surface of the filter cartridge gradually increase, they will block the filter holes at the filter cartridge, causing the pressure difference between the water inlet pipe and the water outlet pipe to change. At this time, if the pressure values ​​of the pressure gauges installed at the water inlet pipe and the water outlet pipe are inconsistent, it means that the filter cartridge needs to be cleaned. By manually turning the crank, the bristles will clean the impurities attached to the surface of the filter cartridge, and the stop valve at the sewage pipe will be opened to discharge the cleaned impurities from the inside of the shell. This can identify whether the filter screen inside the filter needs to be cleaned, saving manpower.

[0021] (2) In this solution, the gap between the top cover and the shell is filled with the second sealing rubber ring to achieve a sealing effect, and the top cover can be quickly and easily disassembled and assembled through the quick-release bolts, thereby facilitating the inspection and replacement of the filter cartridge.

[0032] A crank 11 is rotatably connected to the middle of the top cover 10, and the bottom end of the crank 11 extends to the inner side of the filter cartridge 7. A brush 12 is installed on the outer wall of the bottom end of the crank 11 to abut against the inner wall of the filter cartridge 7.

[0033] Pressure gauges 16 are installed at both the water inlet pipe 2 and the water outlet pipe 3;

[0034] It should be noted that when the hand-cranked filter cleaning structure is in use, the liquid to be filtered is introduced into the inner side of the shell 1 through the water inlet pipe 2, filtered by the filter cartridge 7, and then discharged through the water outlet pipe 3, while the impurities in the liquid are retained on the surface of the filter cartridge 7. When the attachments on the surface of the filter cartridge 7 gradually increase, the filter holes at the filter cartridge 7 will be blocked, causing the pressure difference between the water inlet pipe 2 and the water outlet pipe 3 to change. At this time, if the pressure values ​​of the pressure gauges 16 installed at the water inlet pipe 2 and the water outlet pipe 3 are inconsistent, it means that the filter cartridge 7 needs to be cleaned. By manually holding the crank 11 and rotating it, the bristles 12 will clean the impurities attached to the surface of the filter cartridge 7, and the stop valve 5 at the sewage pipe 4 will be opened to discharge the cleaned impurities from the inner side of the shell 1. It can identify whether the filter screen inside the filter needs to be cleaned, thus saving manpower.

[0035] like Figure 1 , Figure 5 As shown, a quick-release bolt 17 is inserted into the edge of the top cover 10, and the quick-release bolt 17 is screwed with the top edge of the shell 1, and a second sealing rubber ring 13 is inlaid at the edge of the lower surface of the top cover 10, and the second sealing rubber ring 13 is in contact with the top of the shell 1;

[0036] It should be noted that the second sealing rubber ring 13 is used to fill the gap between the top cover 10 and the housing 1 to achieve a sealing effect, and the top cover 10 can be quickly and conveniently disassembled and assembled through the quick-release bolts 17, so that the filter cartridge 7 can be easily inspected and replaced.

[0037] like Figure 1 As shown, Figure 5 As shown, a bearing 15 which is interference-connected with the crank 11 is installed at the joint of the top cover 10 and the crank 11, and a third sealing rubber ring 14 is installed below the bearing 15, and the inner wall of the third sealing rubber ring 14 abuts against the outer wall of the crank 11;

[0038] It should be noted that while ensuring the sealing of the joint between the crank 11 and the top cover 10, the rotation accuracy of the crank 11 is also guaranteed.

[0039] like Figure 5 As shown, a plurality of bristles 12 are arranged at radial positions of the crank 11;

[0040] It should be noted that the filter cartridge 7 can be cleaned quickly.

[0041] like Figure 2 As shown, the water outlet pipe 3 is located above the water inlet pipe 2, and the annular boss 6 is located between the water outlet pipe 3 and the water inlet pipe 2;

[0042] It should be noted that the liquid enters the inner side of the shell 1 through the water inlet pipe 2, is filtered by the filter cartridge 7, and is discharged through the water outlet pipe 3, while the impurities in the liquid are retained on the surface of the filter cartridge 7. When the attachments on the surface of the filter cartridge 7 gradually increase, the filter holes at the filter cartridge 7 will be blocked, causing the pressure difference between the water inlet pipe 2 and the water outlet pipe 3 to change.

[0043] During use: the liquid to be filtered is introduced into the inner side of the shell 1 through the water inlet pipe 2, filtered by the filter cartridge 7, and then discharged through the water outlet pipe 3, while the impurities in the liquid are retained on the surface of the filter cartridge 7. When the attachments on the surface of the filter cartridge 7 gradually increase, the filter holes at the filter cartridge 7 will be blocked, causing the pressure difference between the water inlet pipe 2 and the water outlet pipe 3 to change. At this time, if the pressure values ​​of the pressure gauges 16 installed at the water inlet pipe 2 and the water outlet pipe 3 are inconsistent, it means that the filter cartridge 7 needs to be cleaned. By manually turning the crank 11, the bristles 12 will clean the impurities attached to the surface of the filter cartridge 7, and open the stop valve 5 at the sewage pipe 4 to discharge the cleaned impurities from the inner side of the shell 1.

[0044] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
