[0015] Compared with the prior art, this utility model provides a reusable, long-life pre-pump filter with the following advantages:
[0016] 1. Through the design of cooling components, sealing plates, air inlets, heat conduction plates, cooling fans, heat dissipation fins, fixing bolts, fixing holes, fixing screws, and spiral grooves, a cooling component is located in the middle of the top cover. This component directly cools the dust-laden gas entering the filter cartridge, utilizing temperature changes to alter the physical properties of dust particles and improve the separation efficiency of dust and gas. A heat conduction plate is placed between the cooling component and the top cover to quickly transfer heat from the filter cartridge to the cooling component. The cooling fan inside the cooling component and the heat dissipation fins on the side work together to accelerate airflow, increase the heat dissipation area, ensure efficient heat dissipation, and maintain good cooling performance. The cooling component is powered by an external power source to ensure stable operation. The array's fixing bolts securely fasten it to the top cover, preventing the cooling components from loosening and affecting performance during operation. The sealing plate is fixedly connected to the top cover via fixing screws and fixing holes, ensuring the stability of the connection. At the same time, the sealing plate enhances the sealing performance of the filter cartridge. The air outlet in the middle of its interior is used to discharge filtered gas and prevent unfiltered gas from leaking. The right side of the spiral groove at the bottom of the top cover is connected to the air inlet and the air outlet in the middle of the sealing plate. After the dust-laden gas enters through the air inlet, it forms a spiral airflow under the action of the spiral groove, making the gas more evenly distributed in the filter cartridge, increasing the contact area with the filter medium, improving the filtration effect, and facilitating the flow of gas in the filter cartridge, ensuring the overall high-efficiency operation of the filter.
[0017] 2. Through the arrangement of baffles, support blocks, connecting plates, positioning grooves, and positioning protrusions, the baffles on the upper and lower sides inside the filter cartridge body, along with the support blocks on the outer side, maintain a distance from the top sealing plate and bottom of the filter cartridge body, forming a specific airflow channel. When dust-laden gas flows inside the filter cartridge, the baffles act as buffers and guides, making the airflow more stable and orderly. The internal array of vent holes allows the airflow to pass evenly, avoiding localized excessively fast or slow airflow, ensuring full contact between the airflow and the filter medium inside the filter cartridge body, thereby improving filtration efficiency, reducing filtration dead zones, and enhancing the overall filtration effect. Positioning grooves are set inside the connecting plates at the top of the filter cartridge body and the bottom of the top cover, and positioning protrusions are correspondingly set on the upper and lower sides of the sealing plate. This design of corresponding positioning protrusions and positioning grooves enables precise positioning during installation, ensuring that the sealing plate is accurately installed in the appropriate position, guaranteeing the seal between the sealing plate and the filter cartridge body. Good sealing performance prevents dust-laden gas from leaking from the seal without effective filtration, improving the working reliability and filtration quality of the filter, helping to maintain a stable airflow environment inside the filter, and ensuring the normal operation of the filtration process.

Heat dissipation fins 22 are provided on the side of the cooling component 14. The cooling component 14 is powered by an external power source.
[0029] The cooling component 14 is provided with fixing bolts 20 on the outer side, and the cooling component 14 is fixedly connected to the upper cover 3 by the fixing bolts 20.
[0030] A fixing screw 15 is provided at the bottom of the upper cover 3, and a fixing hole 12 is provided inside the sealing plate 10. The sealing plate 10 is fixedly connected to the upper cover 3 through the fixing screw 15 and the fixing hole 12. An air vent is provided in the middle of the sealing plate 10.
[0031] A spiral groove 17 is provided at the bottom of the top cover 3. The right side of the spiral groove 17 is connected to the air inlet 16, and the spiral groove 17 is connected to the air outlet in the middle of the sealing plate 10.
[0032] The filter cartridge body 1 has baffles 4 on the upper and lower sides inside, and a support block 8 is provided on the outer side of the baffles 4. The baffles 4 maintain a distance from the top sealing plate 10 and the bottom of the filter cartridge body 1 through the support block 8. The baffles 4 have air holes arranged in an array inside.
[0033] A connecting plate 7 is provided at the top of the filter cartridge body 1 and the bottom of the upper cover 3. A positioning groove 9 is provided on the inner side of the connecting plate 7. Positioning protrusions 13 are provided on the upper and lower sides of the sealing plate 10, and the positioning protrusions 13 correspond to the positioning grooves 9.
[0034] A hook groove 19 is provided on the outer side of the connecting plate 7, and a hook bolt 2 is provided on the outer side of the hook groove 19. The filter cartridge body 1 and the upper cover 3 are fixedly connected by the hook bolt 2. A positioning hole 11 is provided inside the sealing plate 10, and a positioning pin 21 corresponding to the positioning hole 11 is provided at the bottom of the connecting plate 7 of the upper cover 3.
[0035] In this embodiment, the specific implementation steps of a reusable long-life pre-pump filter are as follows: Check the stability of each component connection, especially the connection between the filter cartridge body 1 and the upper cover 3 via the hook bolts 2, and check the tightness of the fit between the hook groove 19 on the outer side of the connecting plate 7 and the hook bolts 2; simultaneously check the connection between the sealing plate 10 and the upper cover 3, confirming that the positioning protrusions 13 on the upper and lower sides of the sealing plate 10 are accurately embedded in the positioning grooves 9 on the inner side of the connecting plate 7, and that the sealing plate 10 is firmly fixed to the upper cover 3 via the fixing screws 15 and fixing holes 12; confirm the installation of the cooling component 14, ensuring that the fixing bolts 20 on the outer side of the cooling component 14 are tightly fixed to the upper cover 3, and connect the external power supply of the cooling component 14 to ensure normal power supply and operation. Dust-laden gas enters the filter through the air inlet 16. After entering, the gas flows along the spiral groove 17 at the bottom of the upper cover 3. Due to the special structure of the spiral groove 17, the gas forms a spiral airflow. This spiral airflow allows the dust-laden gas to be more evenly distributed within the internal space of the filter cartridge body 1. The cooling component 14 begins to work, using the heat-conducting plate 18 to heat the filter cartridge body 1... Heat is conducted from the inside, and the cooling fan inside the cooling component 14 operates, accelerating airflow. At the same time, the heat dissipation fins 22 on the side increase the heat dissipation area, cooling the dust-laden gas. As the gas temperature decreases, the physical properties of the dust particles change. The dust-laden gas flows inside the filter cartridge body 1 and passes through the filter medium 5 filled inside the filter cartridge body 1. During the flow, the baffles 4 on the upper and lower sides inside the filter cartridge body 1 act as buffers and guides. The baffles 4 maintain a distance from the top sealing plate 10 and the bottom through the outer support block 8. The dust-laden gas passes through the air vents arrayed inside the baffles 4, making the airflow contact the filter medium 5 more evenly. The dust particles are intercepted by the filter medium 5. The filtered gas continues to flow and reaches the sealing plate 10. It is discharged from the filter through the air outlet set in the middle of the sealing plate 10. After the equipment has been running for a period of time, it is necessary to check the working status of the cooling component 14, check whether the cooling fan is operating normally, whether there is dust accumulation on the heat dissipation fins 22 affecting the heat dissipation effect, and regularly check the blockage of the filter medium 5. Replace or clean it if necessary.
[0036] like Figure 1 and Figure 4-5As shown, a cooling component 14 is provided at the top center of the upper cover 3, a sealing plate 10 is provided at the bottom of the upper cover 3, an air inlet 16 is provided at the top right side of the upper cover 3, a heat-conducting plate 18 is provided between the cooling component 14 and the upper cover 3, a cooling fan is provided inside the cooling component 14, and heat dissipation fins 22 are provided on the side of the cooling component 14. The cooling component 14 is powered by an external power source, and fixing bolts 20 are arranged on the outer side of the cooling component 14. The cooling component 14 is fixedly connected to the upper cover 3 by the fixing bolts 20. A fixing screw 15 is provided at the bottom of the upper cover 3, a fixing hole 12 is provided inside the sealing plate 10, and the sealing plate 10 is fixedly connected to the upper cover 3 by the fixing screw 15 and the fixing hole 12. An air outlet is provided at the center of the interior of the sealing plate 10, and a spiral groove 17 is provided at the bottom of the upper cover 3. The right side of the spiral groove 17 is connected to the air inlet 16, and the spiral groove 17 is connected to the air outlet in the middle of the sealing plate 10.
[0037] Preferably, a cooling element 14 is provided in the middle of the top of the upper cover 3, which can directly cool the dust-laden gas entering the filter cartridge. The temperature change causes the physical properties of the dust particles to change, improving the separation efficiency of dust and gas. A heat-conducting plate 18 is provided between the cooling element 14 and the upper cover 3, which can quickly conduct heat from the filter cartridge to the cooling element 14. The cooling fan inside the cooling element 14 and the heat dissipation fins 22 on the side work together to accelerate airflow, increase the heat dissipation area, ensure efficient heat dissipation of the cooling element 14, and maintain a good cooling effect. The cooling element 14 is powered by an external power supply to ensure its stable operation. The fixing bolts 20 arranged on the outer side of the cooling element 14 firmly fix it to the upper cover 3 to prevent it from cooling down during operation. Loose parts 14 affect performance. The sealing plate 10 is fixedly connected to the upper cover 3 by the fixing screw 15 and fixing hole 12, ensuring the stability of the connection. At the same time, the sealing plate 10 enhances the sealing performance of the filter cartridge. The air outlet in the middle of its interior is used to discharge the filtered gas and prevent the leakage of unfiltered gas. The right side of the spiral groove 17 at the bottom of the upper cover 3 is connected to the air inlet 16 and the middle air outlet of the sealing plate 10. After the dust-laden gas enters from the air inlet 16, it forms a spiral airflow under the action of the spiral groove 17, which makes the gas more evenly distributed in the filter cartridge, increases the contact area with the filter medium, improves the filtration effect, and helps the gas to circulate in the filter cartridge, ensuring the overall high-efficiency operation of the filter.
[0038] like Figure 1-4As shown, baffles 4 are respectively provided on the upper and lower sides of the filter cartridge body 1. A support block 8 is provided on the outer side of the baffle 4. The baffle 4 maintains a distance from the top sealing plate 10 and the bottom of the filter cartridge body 1 through the support block 8. Ventilation holes are arrayed inside the baffle 4. A connecting plate 7 is provided at the top of the filter cartridge body 1 and the bottom of the top cover 3. A positioning groove 9 is provided on the inner side of the connecting plate 7. Positioning protrusions 13 are respectively provided on the upper and lower sides of the sealing plate 10. The positioning protrusions 13 correspond to the positioning grooves 9.
[0039] Preferably, the baffles 4 set on the upper and lower sides inside the filter cartridge body 1 are maintained at a distance from the top sealing plate 10 and bottom of the filter cartridge body 1 by the outer support block 8, forming a specific airflow channel. When the dust-laden gas flows in the filter cartridge, the baffles 4 play a buffering and guiding role, making the airflow more stable and orderly. The air vents arrayed inside allow the airflow to pass evenly, avoiding local airflow that is too fast or too slow, ensuring that the airflow is in full contact with the filter medium inside the filter cartridge body 1, thereby improving filtration efficiency, reducing filtration dead angles, and improving the overall filtration effect. The connecting plate 7 at the top of the filter cartridge body 1 and the bottom of the top cover 3 is provided with positioning grooves 9 inside, and positioning protrusions 13 are provided on the upper and lower sides of the sealing plate 10 respectively. This design of positioning protrusions 13 corresponding to positioning grooves 9 can achieve precise positioning during installation, ensuring that the sealing plate 10 is accurately installed in the appropriate position, ensuring the sealing performance between the sealing plate 10 and the filter cartridge body 1. Good sealing performance prevents dust-laden gas from leaking from the seal without effective filtration, improves the working reliability and filtration quality of the filter, helps to maintain a stable airflow environment inside the filter, and ensures the normal operation of the filtration work.
[0040] like Figure 1-5 As shown, a hook groove 19 is provided on the outer side of the connecting plate 7, and a hook bolt 2 is provided on the outer side of the hook groove 19. The filter body 1 and the upper cover 3 are fixedly connected by the hook bolt 2. A positioning hole 11 is provided inside the sealing plate 10, and a positioning pin 21 corresponding to the positioning hole 11 is provided at the bottom of the connecting plate 7 of the upper cover 3.
[0041] Optionally, a hook groove 19 is provided on the outer side of the connecting plate 7, and a hook bolt 2 is fitted on its outer side. This design provides a stable and convenient connection between the filter cartridge body 1 and the upper cover 3. The hook bolt 2 can tightly hook the hook groove 19, firmly fixing the filter cartridge body 1 and the upper cover 3 together, effectively preventing the upper cover 3 from loosening or separating due to vibration or other reasons during equipment operation, ensuring the stability of the filter structure and guaranteeing long-term stable operation of the equipment. The sealing plate 10 is provided with a positioning hole 11, and the bottom of the connecting plate 7 of the upper cover 3 is provided with a corresponding positioning pin 21. The positioning pin 21 cooperates with the positioning hole 11 to play a precise positioning role during installation, ensuring that the sealing plate 10 is accurately installed at the corresponding position at the bottom of the upper cover 3, so that the sealing performance between the sealing plate 10, the upper cover 3, and the filter cartridge body 1 reaches the optimal state, further avoiding the problem of dust-laden gas leakage, and improving the filtration effect and overall performance of the filter.
