Description

Technical Field

[0001] This utility model relates to the field of water treatment filtration technology, and in particular to a pre-filter for water treatment with multiple media. Background Technology

[0002] Multi-media filters (also known as mechanical filters or filter beds) use filter media of different densities and particle sizes (such as quartz sand, anthracite, activated carbon, etc.) arranged in layers. Under pressure, they trap suspended solids, colloids, bacteria and other impurities in the water, significantly reducing turbidity (down to below 3 degrees) and partially removing pollutants such as BOD / COD. Pre-filters are needed in water treatment filtration to filter water. However, traditional multi-media filters are inconvenient to replace and clean the filter elements, and disassembly and assembly are relatively troublesome.

[0003] Therefore, those skilled in the art have provided a pre-treatment multi-media filter for water treatment to solve the problems mentioned in the background art. Utility Model Content

[0004] To address the inconvenience of replacing and cleaning filter elements in traditional multi-media filters, and the cumbersome disassembly and assembly process, this utility model provides a pre-filter for water treatment.

[0005] This utility model provides a pre-filter for water treatment with multiple media, employing the following technical solution:

[0006] A pre-filter for water treatment includes a filter housing, an inner cavity of which is provided with a filter element, a pushing assembly on the front of the filter housing, the pushing assembly including a pushing box, a stepper motor fixedly mounted on one side of the inner cavity of the pushing box, a one-way threaded rod fixedly mounted on the output shaft of the stepper motor, a pushing screw block threadedly connected to the surface of the one-way threaded rod, a connecting rod fixedly mounted on one side of the pushing screw block, a connecting assembly provided at one end of the connecting rod, the connecting assembly including a connecting seat and a connecting block, a positioning cylinder fixedly mounted on the top of the connecting seat, a positioning spring fixedly mounted on the top of the inner cavity of the positioning cylinder, a movable plate fixedly mounted on the bottom of the positioning spring, a positioning insert rod fixedly mounted on the inner cavity of the movable plate, and a pull head fixedly mounted on the top of the positioning insert rod.

A stepper motor 402 is fixedly installed on one side of the inner cavity of the feeding box 401. A one-way threaded rod 403 is fixedly installed on the output shaft of the stepper motor 402. A push screw block 404 is threadedly connected to the surface of the one-way threaded rod 403. A connecting rod 406 is fixedly installed on one side of the push screw block 404. A sliding block 405 is fixedly installed on the other side of the push screw block 404. A sliding groove is opened in the inner cavity of the feeding box 401. A positioning bearing is fixedly installed on the other side of the inner cavity of the feeding box 401, and the positioning bearing is rotatably connected to the one-way threaded rod 403.

[0032] In this embodiment: by setting the filter element 2 and the filter housing 1, the normal filtration function of the filter is ensured. By setting the push component 4, the position of the filter element 2 can be adjusted. Controlling the stepper motor 402 to rotate forward can drive the filter element 2 to detach from the filter housing 1. Controlling the stepper motor 402 to rotate in reverse can drive the filter element 2 to insert into the filter housing 1, which is convenient for replacing the filter element 2. The positioning bearing positions the one-way threaded rod 403, making the one-way threaded rod 403 stable and preventing it from tilting. The filter medium can filter water. The filter screen 6 can limit the filter medium. Bolts can be inserted into the mounting hole to fix the device. The water guide pipe 3 is convenient for connecting water pipes.

[0033] Example 2:

[0034] Reference Figure 1 , Figure 3 and Figure 4 A connecting component 5 is provided at one end of the connecting rod 406. The connecting component 5 includes a connecting seat 501 and a connecting block 507. A positioning cylinder 502 is fixedly installed on the top of the connecting seat 501. A positioning spring 503 is fixedly installed on the top of the inner cavity of the positioning cylinder 502. A movable plate 504 is fixedly installed on the bottom of the positioning spring 503. A positioning insert rod 505 is fixedly installed in the inner cavity of the movable plate 504. A pull head 506 is fixedly installed on the top of the positioning insert rod 505. The connecting seat 501 is fixedly connected to the connecting rod 406. The connecting block 507 is fixedly connected to the filter element 2. Guide blocks are fixedly installed on both sides of the movable plate 504. A guide groove is opened in the inner cavity of the positioning cylinder 502.

[0035] In this embodiment: By setting up a connecting component 5, the positioning rod 505 can be disengaged from the connecting block 507 by pulling the pull head 506, making it easy to disassemble the filter element 2. When the pull head 506 is released, the positioning rod 505 can be inserted into the connecting block 507 by the rebound force of the positioning spring 503, thereby installing the filter element 2. The connecting rod 406 can position the connecting seat 501, and the filter element 2 can limit the connection block 507. The guide block and the guide groove are used together to guide the movable plate 504, so that the movable plate 504 is stable when it moves.

[0036] The implementation principle of this utility model is as follows: In use, the stepper motor 402 is turned on to drive the one-way threaded rod 403 to rotate. The one-way threaded rod 403 drives the push screw block 404 to move. The push screw block 404 drives the connecting rod 406 to move. The connecting rod 406 drives the connecting assembly 5 and the filter element 2 to move as a whole, so that the filter element 2 is separated from the filter housing 1. Pulling the pull head 506 upward drives the positioning rod 505 to move upward. The positioning rod 505 is separated from the connecting block 507, which facilitates the disassembly of the connecting block 507 and the filter element 2. At this time, the positioning rod 505 drives the movable plate 504 to move upward, and the positioning spring 503 is compressed. When the pull head 506 is released, the positioning spring 503 rebounds and drives the movable plate 504 back to its original position. The movable plate 504 drives the positioning rod 505 to insert into the connecting block 507, which can stabilize the filter element 2. Bolts are inserted into the mounting hole to fix the mounting base 7, thereby making the device stable.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
