Description

Technical Field

[0001] The utility model relates to the technical field of paint production and processing, and particularly relates to a water-based paint filtering device. Background Art

[0002] With the wide application of water-based paints in the paint industry, their filtering technology becomes particularly important. During the preparation, storage, and use of water-based paints, their quality and stability are often affected by the presence of particles, impurities, or pigment aggregates. Therefore, filtering water-based paints to remove impurities and particulate matter becomes a crucial step in ensuring the paint quality and usage effect.

[0003] However, there are some problems in the design and use of existing water-based paint filtering devices. First of all, traditional filtering devices mostly use fixed filters, which are easily blocked by impurities in the paint during the filtering process, resulting in a decrease in filtering efficiency. Even frequent filter replacements are required, increasing production costs and operational complexity.

[0004] Secondly, for blocked filters, existing cleaning methods mostly involve manual cleaning or disassembling the filter for cleaning. This method is not only cumbersome and inefficient but also easily causes paint waste and environmental pollution during the cleaning process. Especially when dealing with a large amount of water-based paint, this cleaning method is even more difficult to meet the actual needs.

[0005] In view of the above problems, the utility model proposes a filtering device for water-based paints that is convenient for cleaning the filter. The device aims to solve the problems of low filtering efficiency and difficult filter cleaning in the prior art. By designing a new self-cleaning filter structure, it realizes the efficient filtering of water-based paints and the convenient cleaning of the filter. Summary of the Utility Model

[0009] A lower sealing plate is provided on the bottom wall of the cylinder. In the middle of the bottom wall of the lower sealing plate, a housing is provided. One end of a sewage discharge pipe is provided on the side wall of the housing. The upper and lower inner walls of the housing are rotatably connected to a lower fixing rod through a sealing bearing.

The upper and lower inner walls of the housing 9 are rotatably connected through a sealing bearing with a lower fixing rod 11. A through hole 12 communicating with the inner cavity is formed through the outer wall of the lower fixing rod 11. The top end of the lower fixing rod 11 extends into the cylinder 1 and is fixedly connected to the bottom wall of the filter screen 7. A motor 13 is detachably provided on the bottom wall of the housing 9, and the output end of the motor 13 is fixedly connected to the bottom end of the lower fixing rod 11 through a coupling. On one side of the bottom wall of the lower sealing plate 8, a connecting cover 14 is provided. A liquid discharge pipe 15 is inserted into the bottom wall of the connecting cover 14, and a connecting pipe 16 is provided on the outer wall of the liquid discharge pipe 15.

[0024] Furthermore, the outer wall shape of the filter screen 7 is frustum-shaped. The material is conveyed into the hopper 3 and enters the filter screen 7 through the upper fixing rod 6. The material is filtered by the filter screen 7, and the impurities are filtered inside the filter screen 7, and the material flows out of the filter screen 7.

[0025] Furthermore, solenoid valves are provided on the outer walls of the sewage discharge pipe 10, the liquid discharge pipe 15, and the connecting pipe 16, which facilitates controlling the sewage discharge and liquid discharge operations of the sewage discharge pipe 10, the liquid discharge pipe 15, and the connecting pipe 16.

[0026] Furthermore, multiple high-pressure nozzles are arranged in a circumferential gap on the outer wall of the bottom of the circular plate 4. After pressurizing the cleaning liquid, it is transported into the circular plate 4 through the water inlet pipe 5 and sprayed out through the high-pressure nozzles to wash the filter net 7 from the outside to the inside, washing down the impurities on the inner wall of the filter net 7.

[0027] Furthermore, the hopper 3, the upper fixing rod 6, the filter net 7, the lower fixing rod 11, the housing 9, the sewage discharge pipe 10 and the through hole 12 are connected. After pressurizing the cleaning liquid, it is transported into the circular plate 4 through the water inlet pipe 5 and sprayed out through the high-pressure nozzles to wash the filter net 7 from the outside to the inside, washing down the impurities on the inner wall of the filter net 7. Then, it enters the housing 9 through the lower fixing rod 11 and the through hole 12 and is discharged through the sewage discharge pipe 10. The cleaning liquid outside the filter net 7 is discharged through the connecting cover 14 and the drain pipe 15, which facilitates the self-cleaning operation of the filter net 7.

[0028] For those skilled in the art, all the electrical components and parts in this case are common standard parts or parts known to those skilled in the art. Their structures and principles can all be learned by those skilled in the art through technical manuals or obtained through conventional experimental methods.

And according to the actual situation, a suitable controller is selected to meet the control requirements. For the specific connection and control sequence, reference should be made to the following working principle for the sequence of work among the electrical components to complete the electrical connection. The detailed connection means are well-known techniques in the art, and no further description of electrical control will be given.

The materials are filtered by the filter net 7, and the impurities are filtered inside the filter net 7. The materials flow out of the filter net 7 and are discharged through the connecting cover 14 and the connecting pipe 16. The motor 13 drives the lower fixing rod 11 to drive the filter net 7 and the upper fixing rod 6 to rotate. Due to the high-speed rotation of the filter net 7, centrifugal force is generated to throw out the materials, and a rapid filtering operation is performed on the materials. When the self-cleaning operation of the filter net 7 is required, close the solenoid valve on the connecting pipe 16, open the sewage discharge pipe 10 and the drain pipe 15, pressurize the cleaning liquid and transport it into the circular plate 4 through the water inlet pipe 5, spray it out through the high-pressure nozzles, wash the filter net 7 from the outside to the inside, wash down the impurities on the inner wall of the filter net 7, enter the housing 9 through the lower fixing rod 11 and the through hole 12, and be discharged through the sewage discharge pipe 10. The cleaning liquid outside the filter net 7 is discharged through the connecting cover 14 and the drain pipe 15 to complete the self-cleaning operation of the filter net 7.
