Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a novel filter. Background Technology

[0002] Filter valves are typically installed at the inlet of hydraulic control valves, pressure reducing valves, pressure relief valves, and level control valves to remove impurities from the medium and prevent particulate impurities from entering the channel and causing blockages, thereby protecting the equipment on the pipeline.

[0003] For example, patent CN201599489U, entitled "A Filter Valve," discloses a filter that uses a filter element installed on a drain branch pipe with a drain outlet to facilitate wastewater discharge and filter element replacement. However, in this structure, because the flow direction of the medium within the valve body is stable, impurities tend to accumulate more easily on the side of the filter element closer to the outlet. This means the filter element can only filter a significant amount of impurities near the outlet, while other areas accumulate less, resulting in insufficient use of the filter element and requiring replacement only after a short period of use. Utility Model Content

[0004] This utility model provides a novel filter designed to solve the problem in the prior art where, due to the stable flow direction of the medium within the valve body, impurities tend to accumulate on the side of the filter element near the outlet, while other parts accumulate less impurities, resulting in insufficient use of the filter element and the need for replacement or cleaning after a short period of use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This utility model embodiment provides a novel filter, comprising: The valve body includes an inlet channel, an outlet channel, and a filter channel; the inlet channel and the filter channel are connected, and the outlet channel is connected to the side wall of the filter channel; a sealing valve cover is provided at the end of the filter channel away from the inlet channel. A filter assembly includes a filter cylinder with an opening at one end, the open end of the filter cylinder abutting against the end of an inlet channel, and the bottom of the filter cylinder abutting against a sealing valve cover; the outer side of the sealing valve cover is provided with an operating hole corresponding to the bottom of the filter cylinder. The bottom of the filter cartridge is provided with magnetic material, and the magnetic head is located in the operation hole to attract the bottom of the filter cartridge. When the magnetic head is rotated, the magnetic head drives the filter cartridge to rotate.

[0006] In one embodiment, the inner wall of the sealing valve cover is provided with a mounting hole, and the bottom of the filter cylinder mates with the mounting hole; A guide rod is provided at the center of the mounting hole, and a first guide hole is provided at the bottom of the filter cylinder, the first guide hole cooperating with the guide rod; A spring is installed inside the mounting hole, and the spring pushes the bottom of the filter cylinder to abut against the end of the inlet channel.

[0007] In one embodiment, an abutment is provided at the end of the inlet channel near the filter channel, and the spring pushes the filter cylinder to abut against the abutment.

[0008] In one embodiment, a mounting ring groove is provided in the mounting hole, and the spring is disposed in the mounting ring groove.

[0009] In one embodiment, the inner wall of the filter cartridge is provided with an inner connecting piece, and the inner connecting piece is provided with a second guide hole, through which the guide rod passes.

[0010] In one embodiment, both the inner connecting plate and the bottom of the filter cylinder are provided with a plurality of bottom holes.

[0011] In one embodiment, the valve body and the sealing valve cover are made of plastic material.

[0012] In one embodiment, the end of the filter channel away from the inlet channel is provided with an abutment groove, and the sealing valve cover is provided with an abutment boss that mates with the abutment groove.

[0013] The advantages of this invention compared to existing technologies are as follows: In this application, the outlet channel is connected to the side wall of the filter channel.

Therefore, this application provides a magnetic material at the bottom of the filter cartridge, allowing the magnetic head to attract the filter cartridge through the sealing valve cover. When the magnetic head is rotated, it also rotates the filter cartridge, thereby adjusting the position of the filter cartridge relative to the outlet channel. This improves the utilization rate of the filter cartridge and reduces the frequency of cleaning or replacement. Therefore, this application allows adjustment of the filter cartridge position without opening the sealing valve cover, thus preventing media leakage.

[0021] Please see Figure 1-4This utility model provides a novel filter, comprising: Valve body 1, wherein an inlet channel 11, an outlet channel 12 and a filter channel 13 are provided inside the valve body 1; the inlet channel 11 and the filter channel 13 are connected, and the outlet channel 12 is connected to the side wall of the filter channel 13; a sealing valve cover 2 is provided at the end of the filter channel 13 away from the inlet channel 11; The filter assembly includes a filter cylinder 3 with an opening at one end, the open end 31 of the filter cylinder 3 abutting against the end of the inlet channel 11, and the bottom of the filter cylinder 3 abutting against the sealing valve cover 2; the outer side of the sealing valve cover 2 is provided with an operating hole 21 corresponding to the bottom of the filter cylinder 3. The bottom of the filter cylinder 3 is provided with magnetic material, and the magnetic head 4 is located in the operation hole 21 to attract the bottom of the filter cylinder 3. When the magnetic head 4 is rotated, the magnetic head 4 drives the filter cylinder 3 to rotate.

[0022] In this application, the outlet channel 12 is connected to the side wall of the filter channel 13. Therefore, impurities easily accumulate on the side wall of the filter cartridge 3 near the outlet channel 12, which can easily cause blockage of the filter holes on the filter cartridge 3. Therefore, this application provides a magnetic material at the bottom of the filter cartridge 3, so that the magnetic head 4 can attract the filter cartridge 3 through the sealing valve cover 2. When the magnetic head 4 is rotated, it can also drive the filter cartridge 3 to rotate, thereby adjusting the corresponding position of the filter cartridge 3 and the outlet channel 12, which can improve the utilization rate of the filter cartridge 3 and reduce the frequency of cleaning or replacement of the filter cartridge 3. Therefore, this application can adjust the position of the filter cartridge 3 without opening the sealing valve cover 2, thereby avoiding media leakage.

[0023] In this embodiment, the operation hole 21 can reduce the wall thickness of the sealing valve cover 2, so that the magnetic head 4 can better or more easily attract and cooperate with the bottom of the filter cartridge 3.

[0024] In this embodiment, the magnetic head 4 is equipped with a magnet, and the filter cylinder 3 can be inlaid with a magnet at the bottom, or the bottom of the filter cylinder 3 can be made of a magnetic material such as nickel-iron alloy, and a passivation film or chromium can be plated on the surface to prevent corrosion.

[0025] In a further embodiment, the end of the inlet channel 11 near the filter channel 13 is provided with an abutment platform 111, and the open end 31 of the filter cylinder 3 abuts against the abutment platform 111.

[0026] The open end 31 of the filter cylinder 3 abuts against the abutting platform 111, so that when the medium flows in from the inlet channel 11, it will pass through the filter cylinder 3, be filtered by the filter cylinder 3, and flow out from the outlet channel 12.

[0027] In a further embodiment, the inner wall of the sealing valve cover 2 is provided with a mounting hole 22, and the bottom of the filter cylinder 3 is engaged with the mounting hole 22; A guide rod 23 is provided at the center of the mounting hole 22, and a first guide hole 32 is provided at the bottom of the filter cylinder 3. The first guide hole 32 cooperates with the guide rod 23. A spring 5 is provided in the mounting hole 22, and the spring 5 pushes the bottom of the filter cylinder 3 to abut against the abutment platform 111 of the inlet channel 11.

[0028] In this embodiment, by providing spring 5, the filter cylinder 3 can be pushed to maintain a good contact state with the abutment platform 111. When the filter cylinder 3 abuts with the abutment platform 111, a gap is formed between the bottom of the filter cylinder 3 and the mounting hole 22. Thus, when the magnetic suction head 4 attracts the bottom of the filter cylinder 3 in the operation hole 21, the filter cylinder 3 will move towards the operation hole 21, causing the top opening end 31 of the filter cylinder 3 to separate from the abutment platform 111. This reduces the resistance encountered when the filter cylinder 3 rotates, making it easier for the filter cylinder 3 to rotate. The guide rod 23 and the first guide hole 32 cooperate to allow the filter cylinder 3 to move stably along the axial direction of the guide rod 23.

[0029] In a further embodiment, a mounting ring groove 221 is provided in the mounting hole 22, and the spring 5 is disposed in the mounting ring groove 221.

[0030] The spring 5 is located in the mounting ring groove 221, which makes it easier for the filter cartridge 3 to move axially.

[0031] In a further embodiment, the inner wall of the filter cylinder 3 is provided with an inner connecting piece 33, and the inner connecting piece 33 is provided with a second guide hole 34, through which the guide rod 23 passes.

[0032] In this embodiment, the second guide hole 34 is provided to cooperate with the guide rod 23, which enables the filter cylinder 3 to move more stably along the axial direction.

[0033] In a further embodiment, a limiting ring 24 is provided at the root of the guide rod 23, and the diameter of the limiting ring 24 is larger than the diameter of the first guide hole 32. The thickness of the limiting ring 24 is 1mm-3mm.

[0034] In this embodiment, a limiting ring 24 is provided at the root of the guide rod 23, so that the bottom of the filter cylinder 3 can abut against the limiting ring 24 under the attraction of the magnetic head 4. This reduces the contact area between the filter cylinder 3 and the bottom of the mounting hole 22, reduces the resistance to the rotation of the filter cylinder 3, and makes it easier for the filter cylinder 3 to rotate under the drive of the magnetic head 4. Moreover, the thickness of the limiting ring 24 is small, so it does not affect the attraction of the magnetic head 4 to the filter cylinder 3.

[0035] In a further embodiment, both the inner connecting piece 33 and the bottom of the filter cylinder 3 are provided with a plurality of bottom holes.

[0036] A bottom hole is provided through the bottom of the inner connecting piece 33 and the filter cylinder 3, so that the medium can be discharged from the bottom hole as the filter cylinder 3 moves toward the mounting hole 22, making it easier for the filter cylinder 3 to move along the axis.

[0037] In a further embodiment, the valve body 1 and the sealing valve cover 2 are made of plastic material.

[0038] The plastic valve body 1 and sealing valve cover 2 can reduce the dispersion of the magnetic force on the magnetic head 4. At the same time, the valve body 1 can be made of transparent plastic material, which makes it easy to observe the rotation angle of the filter cartridge 3 and the accumulation of impurities.

[0039] In a further embodiment, the end of the filter channel 13 away from the inlet channel 11 is provided with an abutment groove 131, and the sealing valve cover 2 is provided with an abutment boss 25 that cooperates with the abutment groove 131.

[0040] The abutment boss 25 is provided so that it can better fit with the abutment annular groove 131, thereby improving the sealing performance of the sealing valve cover 2 and the opening of the filter channel 13.

[0041] In this application, the medium flows in from the inlet channel 11, is filtered by the filter cartridge 3, and the clean medium flows out from the outlet channel 12 which is connected to the side wall of the filter channel 13.

[0042] Using the principle of magnetic attraction, the magnetic head 4 inside the operation hole 21 of the sealing valve cover 2 is rotated outside the filter to attract and drive the internal filter cylinder 3 to rotate.

[0043] Spring 5 provides axial thrust at the bottom of filter cartridge 3 to ensure that its open end 31 is in close contact with the abutment platform 111 of inlet channel 11, thus ensuring filtration effect.

[0044] When rotation is required, the magnetic head 4 attracts the bottom of the filter cylinder 3 to overcome the force of the spring 5, causing it to move slightly axially and separate from the abutment platform 111, thereby greatly reducing the rotational resistance.

[0045] The guide rod 23 cooperates with the first guide hole 32 and the second guide hole 34 to ensure that the filter cylinder 3 moves smoothly only along the axial direction and rotates stably around the axis.

[0046] The limiting ring 24 restricts the axial movement distance of the filter cartridge 3 and minimizes its contact area during rotation, further reducing rotational resistance.

[0047] The bottom hole on the bottom of the filter cylinder 3 and the inner connecting plate 33 allows the internal medium to be discharged when the filter cylinder 3 moves axially, facilitating its movement.

[0048] The sealing valve cover 2 is sealed by engaging with the abutting boss 25 and the abutting annular groove 131; the valve body 1 can be made of transparent plastic to facilitate observation of the internal condition.

[0049] Compared with the prior art, this application has the following advantages: (1) Online adjustment without opening the cover: The internal filter cartridge 3 can be driven to rotate by external magnetic force without opening the sealing valve cover 2, which completely avoids the risk of media leakage during operation.

[0050] (2) Improve the utilization rate of filter cartridge 3 and extend the maintenance cycle: By rotating the filter cartridge 3, the position opposite to the outlet channel 12 can be changed, thereby making uniform use of the entire filter area of ​​the filter cartridge 3, significantly reducing clogging, and extending the interval between cleaning or replacing the filter cartridge.

[0051] (3) Convenient and reliable operation: driven by magnetic force, simple structure and easy to operate.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
