The beneficial effects of this invention are: by optimizing the filtration device and water flow direction, filtration is more thorough. The filtration device is increased to four stages, with raw water filtered three times and wastewater filtered twice, achieving a purification level of 87.5%, greatly improving the purity of the filtered water. While ensuring filtration effectiveness, the required inlet water pressure is reduced, effectively extending the service life of the filter elements.

[0004] However, the aforementioned industrial parallel inlet four-stage disc filter still has the following drawbacks:

[0005] During prolonged use, the filter element of this disc filter is prone to clogging, requiring regular cleaning or replacement. The filter discs are also difficult to disassemble, increasing maintenance costs and time. Therefore, we need an industrial parallel inlet four-stage disc filter to solve the above problems.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: an industrial parallel inlet four-stage disc filter, including a filter body 1, a top cover 2 installed on the top of the filter body 1, an inlet pipe 3 installed on one side surface of the top cover 2, an inlet valve 301 installed at the upper end of the inlet pipe 3, a filter element shell 13 installed inside the filter body 1, sliding grooves 14 opened on both sides of the inner wall of the filter body 1, sliding blocks 1401 fixedly installed on both sides of the filter element shell 13, one side of the sliding block 1401 slidably connected to the inner wall of the sliding groove 14, a filter element upper shell 7 installed on the top of the filter element shell 13, limit components installed on both sides of the filter element upper shell 7, a filter element assembly provided inside the filter element shell 13, a filter element support 6 installed in the center of the inner cavity of the filter body 1, and the bottom end of the filter element support 6 fixedly installed at the bottom end of the inner cavity of the filter body 1;

[0023] In use, by opening the top cover 2, the filter element housing 13 is slidably connected to the sliding groove 14 inside the filter body 1 via the sliding block 1401. The operator does not need to disassemble too many parts, and can simply remove the filter element housing 13 from the filter body 1 by sliding operation. Since the filter element housing 13 is easy to disassemble and assemble, the risk of component damage caused by complex disassembly and assembly process is reduced, thereby reducing the additional cost caused by replacing damaged parts.

[0024] The limiting assembly includes a limiting plate 8 and a limiting groove 701. The limiting groove 701 is formed on the outer walls of both sides of the filter element upper housing 7. The bottom end of the limiting plate 8 is fitted and connected to the inside of the limiting groove 701. The top end of the limiting plate 8 is L-shaped and extends to the top of the filter element upper housing 7. By manually pressing the top end of the limiting plate 8 and pulling it upward, the filter element upper housing 7 can be moved as a whole, making it easier to replace the filter element assembly.

[0025] The filter element assembly includes a primary filter element 9 and a secondary filter element 10. The primary filter element 9 has a first mounting groove 901 on both sides. The inner wall of the filter element housing 13 is fitted with a first mounting block 902 of the same size as the first mounting groove 901. The outer walls of both sides of the secondary filter element 10 have a second mounting groove 1001. The inner wall of the filter element housing 13 is fitted with a second mounting block 1002 of the same size as the second mounting groove 1001. The second mounting block 1002 fits snugly within the second mounting groove 1001. The design of the first mounting groove 901 and the first mounting block 902, and the second mounting groove 1001 and the second mounting block 1002 being of the same size, ensures that the filter element assembly can be accurately positioned during installation, avoiding problems such as insecure installation or leakage due to positional deviation. The snug connection of the mounting blocks not only enhances the connection strength between the filter element assembly and the filter element housing 13, but also reduces the risk of impurities entering the filter element due to excessive gaps, thus ensuring the filtration effect.

[0026] The filter assembly also includes a third-stage filter 11 and a fourth-stage filter 12. The third-stage filter 11 and the fourth-stage filter 12 are installed inside the filter casing with the same components as the first-stage filter 9 and the second-stage filter 10. By adding the third-stage filter 11 and the fourth-stage filter 12, a more complex and refined filtration system is formed. Each stage of the filter can filter specific pollutants, thereby achieving multi-stage filtration and significantly improving the filtration effect.

[0027] The primary filter element 9, the secondary filter element 10, the tertiary filter element 11, and the quaternary filter element 12 are all equipped with multiple filter discs 15. Each filter disc 15 has several filtration channels at its top and bottom. By setting multiple filter discs 15 and opening filtration channels at the top and bottom of the discs, the total filtration area of ​​the filter can be significantly increased. In the same amount of time, more water can be filtered through the filter media, thereby improving the filtration efficiency.

[0028] The filter element support column 6 is connected through to the bottom of the primary filter element 9, secondary filter element 10, tertiary filter element 11, quaternary filter element 12 and filter element housing 13. The surface of the filter element support column 6 is provided with an anti-corrosion layer. The through connection design of the filter element support column 6 makes the stress between each filter element and the filter element housing 13 more uniform. Under high pressure water flow or vibration environment, the filter element support column 6 can ensure the tight connection between each filter element and the filter element housing 13, avoiding structural damage caused by uneven stress.

[0029] Three support columns 5 arranged in a triangular array are fixedly installed at the bottom of the filter body 1. Anti-slip pads are fixedly installed at the bottom of the support columns 5. A water outlet pipe 4 is installed on one side of the bottom of the filter body 1. A water outlet valve 401 is installed on the surface of the water outlet pipe 4. The anti-slip pads at the bottom of the support columns 5 can increase the friction between the filter body 1 and the ground, preventing the filter body 1 from sliding or shifting due to wet or uneven ground. The water outlet valve 401 installed on the surface of the water outlet pipe 4 can conveniently control the water flow and on / off status. When it is necessary to discharge the filtered water or perform equipment maintenance, it can be achieved simply by adjusting the water outlet valve 401, which improves the convenience and flexibility of operation.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
