Abstract
Description
Technical Field
[0001] This utility model belongs to the field of environmental protection and water treatment technology, specifically relating to a filter cartridge assembly for a pre-pump filter. Background Technology
[0002] Reusable long-life pre-pump filters are filtration devices used at the front end of various pump equipment. They are designed to effectively intercept impurities in the fluid, protect the pump body from wear, corrosion and clogging, while the internal filter media is reusable and has a long lifespan, thereby reducing operating costs and improving equipment reliability.
[0003] However, when the filter media inside the filter is used for a long time, because the filter media is in a static state for a long time, some areas of the filter media are not fully utilized, resulting in a gradual decrease in filtration efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a filter cartridge assembly for a pre-pump filter, in order to solve the problem mentioned in the background art that some areas of the filter material are not fully utilized because the filter material is in a stationary state for a long time.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a filter cartridge assembly for a pre-pump filter, comprising a filter cartridge and a base installed inside the filter cartridge;
[0006] The upper side of the base is provided with multiple filter materials;
[0007] Multiple inner hooks are equidistantly arranged on the circular inner walls of the filter media to adhere to impurities;
[0008] The filter cartridge is equipped with multiple unblocking rods a and b inside.
[0009] Preferably, a base plate is provided on the upper side of the base support, and a plurality of fixing rods a are fixedly connected to the upper outer wall of the base plate to restrict the position of the unblocking rod b.
[0010] Preferably, a plurality of fixing rods b are fixedly connected to the upper outer wall of the base plate on one side of the fixing rod a, so as to restrict the position of the unblocking rod a.
[0011] Preferably, a handle is fixedly connected to the uppermost side of the plurality of fixed rods a, so as to drive the fixed rods a and the base plate to rotate at an angle under the action of external force.
[0012] Preferably, all of the plurality of unblocking rods b are inclined, and the bottom plate has a plurality of holes inside for the flow of medium.
[0013] Preferably, the upper outer wall of the filter cartridge is provided with a cover plate, and an upper pressure plate is provided on the lower side of the cover plate to restrict the position of the filter material.
[0014] Preferably, the upper outer wall of the cover plate has multiple fixing holes.
[0015] Preferably, a base is fixedly connected to the lower outer wall of the filter cartridge to support the filter cartridge.
[0016] Preferably, the upper outer wall of the upper pressure plate has multiple through holes for the flow of medium.
[0017] Compared with the prior art, the present invention provides a filter cartridge assembly for a pre-pump filter, which has the following advantages:
[0018] By installing cleaning rods a and b, when it is necessary to adjust the position of the inactive filter media inside the filter cartridge, the angle of the filter media inside the cartridge can be adjusted by rotating cleaning rods a and b in the back and forth direction. This allows the fluid to be distributed more evenly on the surface of the filter media, balancing the filtration load of each part and preventing premature clogging of the filter media edges or center. At the same time, it allows the filter media to better adapt to the characteristics and distribution of impurities. Furthermore, by adjusting the angle of the filter media, the filtration load is more balanced, which can reduce the degree of local wear on the filter media and extend its service life.

[0025] 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.
[0026] This utility model provides, for example Figure 1-4 A filter cartridge assembly for a pre-pump filter is shown, including a filter cartridge 2 and a base 7 installed inside the filter cartridge 2;
[0027] Multiple filter media 6 are provided on the upper side of the base 7;
[0028] Multiple inner hooks 8 are equidistantly arranged on the circular inner walls of multiple filter media 6 to attach impurities. Fluid containing impurities flows into the filter cartridge 2 from the pipe. The fluid flows in the filter cartridge 2 and begins to contact the filter media 6. During the flow of the fluid between the filter media 6, the impurities are captured and attached by the inner hooks 8 on the circular inner walls of the filter media 6. As filtration continues, the impurities accumulate on the inner hooks 8. The clean fluid passes through the filter media 6, flows out of the filter cartridge 2, and enters the pipeline before the pump to provide clean fluid to the pump and protect the pump body from wear and blockage by impurities. When a large amount of impurities accumulate on the filter media 6, causing the pressure difference between the filter inlet and outlet to reach the set backwash threshold, backwashing or cleaning is prepared. The filter inlet and outlet valves are closed to temporarily isolate the filter from the pipeline system. Backwashing continues for a period of time until the backwashed fluid is basically clear, indicating that most of the impurities on the filter media 6 have been washed away.
[0029] The filter cartridge 2 is equipped with multiple cleaning rods a10 and b11. By operating the corresponding rods, the cleaning rods a10 and b11 can be rotated in the back-and-forth direction. As the cleaning rods a10 and b11 rotate, the filter media 6 adjusts its angle accordingly. During the cleaning process of the filter media 6, the cleaning rods a10 and b11 can also be shaken to adjust their angle. Different angles of the filter media 6 allow the backwash fluid to impact the surface of the filter media 6 and the inner hooks 8 in different directions and angles, more comprehensively and effectively washing away the attached impurities and enhancing the cleaning effect. On the other hand, multi-angle adjustment helps the backwash fluid penetrate deep into the interior of the filter media 6, thoroughly washing out the impurities hidden in the pores of the filter media 6 or the gaps of the inner hooks 8, avoiding impurity residue, and ensuring that the filter media 6 restores its good filtration performance.
[0030] like Figure 4As shown, a base plate 14 is provided on the upper side of the base support 7. Multiple fixing rods a12 are fixedly connected to the upper outer wall of the base plate 14 to limit the position of the unblocking rod b11. Multiple fixing rods b13 are fixedly connected to the upper outer wall of the base plate 14 and located on one side of the fixing rods a12 to limit the position of the unblocking rod a10. A handle 9 is fixedly connected to the uppermost of the multiple fixing rods a12 to drive the fixing rods a12 and the base plate 14 to rotate at an angle under the action of external force.
[0031] The operator holds handle 9 and applies external force to make handle 9 drive fixed rod a12 and base plate 14 to rotate at an angle. As base plate 14 rotates, fixed rod a12 and fixed rod b13 drive unblocking rod b11 and unblocking rod a10 to rotate respectively, thereby driving filter media 6 to adjust the angle. During the adjustment process, closely observe the change in the angle of filter media 6 to judge whether the angle adjustment of filter media 6 has achieved the expected effect and ensure that the appropriate angle is adjusted. At the same time, when the filter media 6 is in the area, the base plate 14 can be lifted to drive a large number of filter media 6 to move upward synchronously.
[0032] like Figure 4 As shown, the multiple unblocking rods b11 are all inclined, and the base plate 14 has multiple holes inside to allow the medium to flow.
[0033] When the inclined unblocking rod b11 rotates and drives the filter media 6 to adjust its angle, it can generate component forces in different directions, making the angle adjustment of the filter media 6 more flexible and diverse, thereby better adapting to the distribution and characteristics of impurities in different fluids and further optimizing the filtration effect.
[0034] like Figure 1 and Figure 2 As shown, a cover plate 3 is provided on the upper outer wall of the filter cartridge 2, and an upper pressure plate 5 is provided on the lower side of the cover plate 3 to restrict the position of the filter material 6. Multiple fixing holes 4 are provided inside the upper outer wall of the cover plate 3.
[0035] After the medium containing impurities enters the filter cartridge 2, a certain flow impact force will be generated. The presence of the upper pressure plate 5 ensures that the filter media 6 will not be displaced due to the flow impact of the medium or its own gravity, and will always remain in the designed filtration position, ensuring the stability and continuity of the filtration process. The fixing hole 4 guides the medium to be filtered into the filter cartridge 2 for filtration.
[0036] like Figure 1 and Figure 2 As shown, a base 1 is fixedly connected to the lower outer wall of the filter cartridge 2 to support the filter cartridge 2, and multiple through holes are opened inside the upper outer wall of the upper pressure plate 5 to allow the medium to flow.
[0037] The base 1 is firmly fixed to the lower outer wall of the filter cartridge 2. The base 1 stably supports the filter cartridge 2, ensuring that the entire filter remains stable during operation and will not tip over due to external force or its own weight.
[0038] The implementation principle of this embodiment is as follows: Fluid containing impurities flows into filter cartridge 2 from the pipe. The fluid flows inside filter cartridge 2 and begins to contact filter media 6. During the flow of fluid between filter media 6, impurities are captured and attached by the inner hooks 8 on the circular inner wall of filter media 6. As filtration continues, impurities accumulate on the inner hooks 8. Clean fluid passes through filter media 6, flows out of filter cartridge 2, and enters the pipeline before the pump, providing clean fluid to the pump and protecting the pump body from wear and blockage by impurities. When a large amount of impurities accumulate on filter media 6, causing the pressure difference between the filter inlet and outlet to reach the set backwash threshold, backwashing or cleaning is prepared. The filter inlet and outlet valves are closed to temporarily isolate the filter from the pipeline system. Backwashing continues for a period of time until the backwashed fluid is basically clear, indicating that most of the impurities on filter media 6 have been washed away. The corresponding operating rod drives the unblocking rods a10 and b11 to rotate in the front and back directions. As the cleaning rods a10 and b11 rotate, the filter media 6 adjusts its angle accordingly. During the cleaning process, the cleaning rods a10 and b11 can also be shaken to adjust their angle. Different angles of the filter media 6 allow the backwash fluid to impact the surface of the filter media 6 and the inner hooks 8 in different directions and angles, more comprehensively and effectively washing away the attached impurities and enhancing the cleaning effect. On the other hand, multi-angle adjustment helps the backwash fluid penetrate deep into the interior of the filter media 6, thoroughly washing out the impurities hidden in the pores of the filter media 6 or the gaps in the inner hooks 8, avoiding impurity residue, and ensuring that the filter media 6 restores its good filtration performance.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
