Description

Technical Field

[0001] The utility model relates to the technical field of precision filters, and more specifically, to a precision filter with a replaceable filter element. Background Art

[0002] A precision filter is a device used to filter impurities such as liquid suspensions and sediments. In recent years, with the advancement of materials science and manufacturing technology, the performance of precision filters has been further improved, providing effective filtering operations for all walks of life and improving product quality. Since the filter element is prone to clogging during a long period of filtering impurities, if it is not cleaned or replaced in time, the entire filter may be damaged and may also cause production interruptions. However, existing precision filters usually use fixed filter elements, which directly fix the filter element inside the device, making it inconvenient to clean and replace the filter element, which not only greatly reduces the service life of the equipment, but also increases the maintenance cost of the equipment to a certain extent. In order to address the deficiencies of the prior art, we propose a precision filter with a replaceable filter element. Utility Model Content

The inner wall of the other connecting part 22 is slidably connected with a sliding rod 25. The inner wall of the mounting frame 21 is threadedly connected with a threaded column 26, and a handle 27 is welded on the outer surface of the upper end of the threaded column 26. The outer surface of the lower end of the threaded column 26 is fixedly installed with a precision filter element 28.

[0024] The driving device 7 is fixedly mounted on one side outer surface of the filter bin 1, the water inlet pipe 9 is fixedly mounted on the outer surface of the filter bin 1, the mounting frame 21 is slidably connected to the inner outer surface of the filter bin 1, the threaded screw 23 is rotatably connected to the inner wall of the fixed block 4, the first motor 24 is fixedly mounted on the lower inner wall of the fixed block 4, and the slide bar 25 is fixedly mounted on the inner wall of another fixed block 4;

[0025] By starting the No. 1 motor 24 to drive the threaded screw 23 to rotate, the rotation of the threaded screw 23 drives the connecting piece 22 to move upward, thereby driving the mounting frame 21 to slide upward on the inner wall of the filter chamber 1, so that the precision filter element 28 leaks out of the filter chamber 1, and then the handle 27 is turned to drive the threaded column 26 to rotate on the inner wall of the mounting frame 21, so as to take out the precision filter element 28.

[0026] Among them, the sewage discharge component 3 includes a disc 31, a sewage discharge pipe 32 is fixedly installed on the upper outer surface of the disc 31, a connecting pipe 33 is rotatably connected to the lower outer surface of the disc 31, a hollow bucket 34 is fixedly installed on the outer surface of one side of the connecting pipe 33, a worm gear 35 is fixedly installed on the outer surface of the lower end of the connecting pipe 33, a worm 36 is meshed on the outer surface of the worm gear 35, and a second motor 37 is fixedly installed on the outer surface of one end of the worm 36.

[0028] By starting the No. 2 motor 37 to drive the worm gear 35 to rotate, the rotation of the worm gear 35 drives the connecting pipe 33 to rotate on the lower outer surface of the disc 31, so that the hollow bucket 34 is sequentially fitted under the through hole 38. At this time, the drain pipe 32 is opened to allow air to pass from the drain pipe 32 through the connecting pipe 33 to the interior of the precision filter element 28, so that an air pressure difference is generated inside the precision filter element 28. The air pressure difference causes impurities attached to the inner wall of the precision filter element 28 to fall down and then be discharged from the drain pipe 32.

[0029] The diameter of the threaded column 26 is greater than the diameter of the precision filter element 28 . Four precision filter elements 28 are provided, and the four precision filter elements 28 are evenly distributed below the mounting frame 21 .

[0031] The working process of the utility model is as follows:

[0032] First, place the device in a suitable working area, then connect the water inlet pipe 9, and let the water to be filtered enter the bottom of the inner cavity of the filter chamber 1 through the water inlet pipe 9. At this time, the internal water slowly rises and enters the interior of the precision filter element 28 from the through hole 38. Then the water filtered by the precision filter element 28 is located on the upper outer surface of the disc 31, and finally discharged through the water outlet pipe 8. When the precision filter element 28 needs to be cleaned, the second motor 37 drives the worm gear 35 to rotate, and the rotation of the worm gear 35 drives the connecting pipe 33 to rotate on the lower outer surface of the disc 31, so that the hollow bucket 34 is successively attached to the bottom of the through hole 38. At this time, the drain pipe 32 is opened to allow air to pass from the drain pipe 32 through the connecting pipe 33 to the interior of the precision filter element 28, so that an air pressure difference is generated inside the precision filter element 28. The air pressure difference causes impurities attached to the inner wall of the precision filter element 28 to fall down, and then When the precision filter element 28 needs to be replaced after being discharged from the sewage pipe 32, first start the driving device 7 to drive the U-shaped fixing part 6 to rotate, so that the round head cover 5 slides on the upper outer surface of the filter bin 1 and leaves the top of the filter bin 1, then start the No. 1 motor 24 to drive the threaded screw 23 to rotate, and the rotation of the threaded screw 23 drives the connecting part 22 to move upward, thereby driving the mounting frame 21 to slide upward on the inner wall of the filter bin 1, so that the precision filter element 28 leaks out of the filter bin 1, and then rotate the handle 27 to drive the threaded column 26 to rotate on the inner wall of the mounting frame 21, so as to take out the precision filter element 28. By utilizing the above structure, the precision filter element 28 is driven to leak out of the filter bin 1 by starting the No. 1 motor 24, and then the threaded column 26 is rotated to make the precision filter element 28 detach from the mounting frame 21, which greatly facilitates the replacement and cleaning of the precision filter element 28 and improves the service life of the filtering equipment.
