[0045] Please refer to Figure 1 - Fig.10 In one embodiment of the utility model, an air purification filter element 100 for an industrial dust collector is provided, wherein the filter element 100 comprises: an air inlet cover 10, a connector 20, a support net 30, a binding belt 40 and an end cover 50.

[0046] The air inlet cover 10 is provided with a slot 11, and the surface of the air inlet cover 10 is recorded as a first surface S1. The connecting member 20 is provided with a latch 21, and by rotating the air inlet cover 10, the latch 21 engages with the slot 11, and the connecting member 20 is fixedly connected to the air inlet cover 10. The branch net 30 is provided at one end of the connecting member 20 away from the air inlet cover 10, and the branch net 30 is fixedly connected to the connecting member 20, and the length of the branch net 30 is recorded as L. The binding strap 40 is provided on the outside of the branch net 30, and the distance between the first binding strap 41 and the second binding strap 42 is recorded as P, and the relationship: P=L / 3 is satisfied. The end cover 50 is provided on the side of the branch net 30 away from the connecting member 20, and the end cover 50 is fixedly connected to the branch net 30. The distance from the first binding strap 41 to the air inlet cover 10 is recorded as P1, and the distance from the second binding strap 42 to the end cover 50 is recorded as P2, and the relationship is satisfied: P1=P2=P / 2.

[0047] Among them, by rotating the air inlet cover 10 to engage the latch teeth 21 with the latch groove 11, a quick and stable connection can be achieved. This design simplifies the installation and disassembly process of the filter element 100, while ensuring the firmness and air tightness of the connection. Industrial dust collectors need to frequently replace and clean the filter element 100. The quick disassembly design improves maintenance efficiency and reduces downtime. The branch net 30 is fixed to the end of the connector 20 that is away from the air inlet cover 10, ensuring the overall structural stability of the filter element 100. The length L of the branch net 30 provides sufficient support and filtering area for the entire filter element 100. The length L of the branch net 30 determines the filtering efficiency and service life of the filter element 100. The appropriate length and fixing method ensure the stability of the filter element 100 during use. The distance between the two straps 40 is set to L / 3 to ensure that the straps 40 can effectively support and fix the branch net 30 to prevent the branch net 30 from deformation or displacement during use. The setting of P1 and P2 makes the positions of the straps 40 evenly distributed, further increasing the stability of the branch net 30. Through the design of P=L / 3 and P1=P2=P / 2, the position of the strap 40 can be evenly distributed over the length of the branch net 30, ensuring that each section of the branch net 30 can be supported and fixed by the strap 40, thereby improving the overall structural stability and durability of the filter element 100.

[0048] Preferably, the connecting member 20 includes a fixing portion 22. The fixing portion 22 is integrally formed with the connecting member 20 and is circular.

[0049] The integrally formed fixing portion 22 has no connection points or welding points in the structure, which increases the overall stability and durability of the filter element 100 and can withstand higher mechanical stress and vibration. The integrally formed design can ensure that there is no gap between the fixing portion 22 and the connecting member 20, reducing air leakage. The circular design facilitates the cylindrical filter screen 60 to be fixedly connected to the connecting member 20 by inserting the fixing portion 22, which simplifies the installation and removal process of the filter screen 60 and improves the convenience and speed of operation.

[0050] Preferably, the filter element 100 further includes a filter screen 60. The mesh surface of the filter screen 60 is integrally formed with diamond-shaped through holes, the diamond-shaped through holes support the filter screen 60, the filter screen 60 is fixedly connected to the end cover 50, the filter screen 60 is cylindrical, and the radius of the circular surface is equal to the radius of the fixing portion 22. The filter screen 60 is inserted into the fixing portion 22, and the filter screen 60 is fixed to the connecting member 20.

[0051] Among them, the mesh surface of the filter 60 is integrally formed with diamond-shaped through holes, and this design can increase the overall rigidity and strength of the filter 60. The structure of the diamond-shaped through holes can increase the effective filtering area and ventilation of the filter 60. The air circulation efficiency is improved, and the filtering capacity of the filter element 100 is enhanced, so that it can more effectively capture and filter dust particles in the air. The filter 60 is cylindrical, and the radius of the circular surface is equal to the radius of the fixing part 22, ensuring a close fit between the filter 60 and the fixing part 22. The filter 60 can be fixed to the fixing part 22 by a simple insertion action, which simplifies the assembly process and reduces production time and cost. The filter 60 is fixed by inserting the fixing part 22, which is easy to disassemble and replace. When the filter 60 needs to be cleaned or replaced, it can be operated quickly and easily, reducing equipment downtime and improving maintenance efficiency.

[0052] More preferably, when viewed along a direction perpendicular to the first surface S1 , the binding strap 40 is located on a side of the support net 30 facing away from the filter net 60 .

[0053] The binding belt 40 is located outside the support net 30 and away from the filter net 60, which is convenient for operation when installing and removing the filter element 100. The operator can more conveniently adjust and fix the binding belt 40, thereby improving the efficiency of installation and removal.

[0054] More preferably, when viewed along a direction parallel to the first surface S1 , the air inlet cover 10 is located on a side of the branch net 30 facing away from the end cover 50 , and the branch net 30 is located between the air inlet cover 10 and the end cover 50 .

[0055] Among them, the air inlet cover 10 is arranged on the side of the branch net 30 away from the end cover 50, which ensures that the path of air flowing through the filter element 100 is relatively smooth. The air flow can smoothly enter from the air inlet, pass through the branch net 30 and the filter screen 60, and then reach the end cover 50 for discharge. This design can reduce air flow resistance and improve filtration efficiency. The air inlet cover 10 and the end cover 50 are respectively arranged at both ends of the filter element 100, and the branch net 30 is located between the two, which is convenient for the installation and maintenance of the filter element 100. When the filter element 100 needs to be replaced or cleaned, it is only necessary to operate the air inlet cover 10 and the end cover 50 respectively, which simplifies the steps of installation and maintenance and improves work efficiency. The branch net 30 is located between the air inlet cover 10 and the end cover 50, providing additional support and fixing. The stability of the overall structure of the filter element 100 is enhanced, and the filter element 100 is prevented from being deformed or displaced during use, ensuring its long-term reliable operation. This layout can effectively separate pollutants in the air and prevent them from backflowing or secondary pollution in the filter element 100.

[0056] More preferably, when viewed along a direction parallel to the first surface S1 , the air inlet cover 10 , the first binding strap 41 , the second binding strap 42 and the end cover 50 are sequentially arranged on the filter element 100 .

[0057] Among them, by sequentially arranging the air inlet cover 10, the bandage 40 and the end cover 50, a uniform force distribution can be formed in the entire filter element 100 structure. The deformation or damage of the filter element 100 caused by uneven force during use is avoided, and the structural stability of the filter element 100 is ensured. The sequential arrangement of the air inlet cover 10, the bandage 40 and the end cover 50 forms a clear airflow path. It is ensured that after the air enters from the air inlet cover 10, it passes through the part of the filter element 100 fixed by the bandage 40 and then is discharged from the end cover 50. This can effectively reduce the turbulence of the airflow and improve the filtering efficiency. The various components are arranged in sequence, making the filter element 100 easier to install and maintain. When replacing or cleaning the filter element 100, the various components are disassembled and installed in sequence, which simplifies the operation process and reduces the maintenance time and difficulty. The position of the bandage 40 can help fix the filter element 100 to prevent it from being displaced under the impact of the airflow. Ensure that the filter screen 60 is always in the best filtering position to improve the filtering effect of the air.

[0058] More preferably, the side of the branch net 30 where the binding belt 40 is provided is serrated, and air flows out through the branch net 30 . The serrated branch net 30 reduces the rebound of dust.

[0059] Among them, the serrated surface of the branch net 30 increases the complexity of the air flow path. This complex path makes it easier for dust particles to be captured when the air passes through the filter element 100, thereby improving the filtration efficiency. The serrated structure can effectively destroy the vortex and reflection in the airflow. It prevents dust particles from rebounding back into the airflow on the surface of the filter element 100, ensuring that more dust is captured and retained by the filter element 100, thereby improving the filtration performance. The serrated design increases the surface area and contact points of the branch net 30. This structure enhances the rigidity and strength of the branch net 30, can better support the material of the filter element 100, and prevents deformation under high-pressure airflow. The bandage 40 is arranged on one side of the serrated branch net 30, which can more firmly fix the branch net 30. The combination of the bandage 40 and the serrated branch net 30 provides stronger support and fixation, preventing the branch net 30 from being displaced under the impact of airflow. The serrated structure increases the surface area compared to the plane. The larger surface area provides more contact between the filter medium and the air, thereby improving the overall filtration efficiency. The serrated design allows the airflow to be more evenly distributed at the branch net 30. The even airflow distribution reduces excessive wear of certain areas of the filter element 100 and extends the service life of the filter element 100.

[0060] Preferably, the filter element 100 further includes a dust sensor 70 . The dust sensor 70 is disposed on the end cover 50 and is located on a side of the end cover 50 close to the branch net 30 .

[0061] Among them, the dust sensor 70 near the branch net 30 can directly contact the air after passing through the filter net 60. This can provide more accurate dust concentration data to reflect the actual working condition of the filter element 100. The dust sensor 70 is located near the branch net 30 and can monitor the degree of blockage of the filter element 100. When a large amount of dust accumulates in the filter element 100, the sensor can detect it in time and send a signal to clean or replace the filter element 100 to ensure the continuous and efficient operation of the dust collector. The dust sensor 70 arranged on the end cover 50 is not directly exposed to unfiltered air. The service life of the sensor is extended, the maintenance requirements are reduced, and the reliability and accuracy of the sensor are ensured. The sensor is arranged on the end cover 50, which is more convenient for installation and maintenance. When replacing the filter element 100 or performing maintenance, the sensor can be easily checked and replaced, reducing maintenance costs and time. The position close to the branch net 30 and the end cover 50 can better protect the sensor from mechanical damage. The risk of sensor damage is reduced and the reliability and durability of the entire system are improved. The sensor is located on the end cover 50 without interfering with the main air flow path. The smooth and uniform air flow is ensured, the filtering efficiency is improved, and the sensor can accurately detect the dust concentration in the air. The sensor is arranged on the end cover 50 and can be easily connected to the control system. The arrangement of the data line and the signal line is simplified, and the line complexity and failure rate are reduced. The dust sensor 70 provides real-time data and can be used in conjunction with the intelligent control system. By analyzing the sensor data, the system can automatically adjust the operating parameters of the dust collector, realize intelligent management, and improve efficiency and energy saving effects.

[0062] More preferably, the dust sensor 70 detects the dust concentration inside the filter 60 , the filter element 100 filters the air, and when the dust concentration is higher than a predetermined value, the dust sensor 70 prompts that the filter element 100 needs to be cleaned.

[0063] Among them, when too much dust accumulates inside the filter element 100, its filtration efficiency will decrease. By monitoring the dust concentration, the filter element 100 can be cleaned or replaced in time before it fails, ensuring that the filter element 100 always maintains an efficient working state. Regular cleaning of the filter element 100 can prevent it from being damaged due to excessive clogging. Timely cleaning can extend the service life of the filter element 100, reduce the frequency of replacement, and reduce the cost of use. A clogged filter element 100 will increase the burden on the equipment and reduce the overall efficiency of the dust collector. By cleaning the filter element 100 in time, it can ensure that the equipment runs smoothly and improve the overall work efficiency and production capacity. An over-clogged filter element 100 may cause the equipment to overheat or other failures. Cleaning the filter element 100 in advance can prevent the equipment from being damaged due to the clogging of the filter element 100, reducing maintenance costs and downtime. When the filter element 100 is clogged, the filtration effect decreases, which may cause insufficiently filtered air to be discharged. By monitoring and cleaning the filter element 100, it can be ensured that the quality of the discharged air meets the standard and protects the working environment and personnel health. The dust sensor 70 can provide real-time data to facilitate the system to respond. Through the monitoring of intelligent sensors, automated management can be achieved, human intervention can be reduced, and the efficiency and accuracy of maintenance management can be improved. An efficient filtration system can reduce energy consumption and emissions. By keeping the filter element 100 clean, the energy consumption of the system can be reduced, the energy utilization efficiency can be improved, and it can help save energy and reduce emissions. It may be difficult for users to judge when the filter element 100 needs to be cleaned. The sensor prompt function can help users perform maintenance in a timely manner and reduce the blindness and inconvenience of maintenance.

[0064] Preferably, the connector 20 includes a sealing groove 23. The sealing groove 23 is located at one end of the connector 20 away from the support net 30, and the sealing groove 23 is integrally formed on the connector 20. By providing a sealing ring on the connector 20, the air tightness between the connector 20 and the air inlet cover 10 is improved.

[0065] Among them, in the industrial dust collector, it is necessary to ensure that the air entering the dust collector will not leak at the connection part after being filtered by the filter element 100. The design of the sealing groove 23 and the sealing ring can effectively prevent the air from directly entering or leaving the dust collector around the filter element 100, thereby ensuring the filtering efficiency and working effect of the dust collector. If there is a poor air tightness between the connector 20 and the air inlet cover 10, it may cause unfiltered air to enter the device around the filter element 100 or the filtered air to escape, thereby affecting the overall efficiency and operating stability of the dust collector. By adding the sealing groove 23 and the sealing ring, the occurrence of this situation can be effectively reduced, ensuring that the air can only be filtered through the filter element 100. A good airtight design can reduce the risk of equipment damage caused by air leakage, extend the service life of the equipment, and reduce maintenance costs and downtime. Many industrial equipment need to comply with specific industrial standards and safety specifications during design and manufacturing, including requirements for air tightness. By adopting the sealing groove 23 and the sealing ring, it can be ensured that the equipment design meets these standard requirements and ensures the stable and safe operation of the equipment under various working conditions.

[0066] Thus, by rotating the air inlet cover 10 and engaging the latch teeth 21 with the latch grooves 11, the convenience of disassembling and assembling the filter element 100 is improved, and the two straps 40 are arranged on the outside of the branch net 30 to prevent the filter element 100 from being deformed.

[0067] The above-described embodiments only express several embodiments of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
