[0002] As a core component of industrial dust removal systems, the accurate evaluation of the filtration performance of dust collector filter bags is crucial. Various filtration performance testing devices have emerged to address this need. These devices typically include key components such as pipelines that simulate the flow of dust-laden air, sealed test chambers for installing filter bags, dust injection devices, and sensors for detecting parameters such as differential pressure and flow rate. The aim is to objectively evaluate the filtration effect of filter bags under laboratory conditions.

[0003] However, in practical applications, especially in continuous testing scenarios, existing testing devices require a long time to disassemble the old filter bag and install the new filter bag after each filter bag test. This repeated disassembly and installation process is not only time-consuming and reduces the overall testing efficiency, but also easily interrupts the continuity of the testing process, making it difficult to meet the urgent industrial demand for rapid and efficient performance screening and evaluation of batches of filter bags.

[0004] In view of this, a filtration testing device for dust collector filter bags is proposed. Utility Model Content

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Please see Figure 1-4 .

[0026] This utility model relates to a filtration testing device for dust collector filter bags, comprising a workbench 1 and a testing chamber 2 fixedly connected to the workbench 1. An mounting plate 3 is fixedly connected to the workbench 1, and a mounting block 31 is slidably mounted on the mounting plate 3. A testing pipe 8 is fixedly connected to the mounting block 31, and a dust inlet 83 is provided on the testing pipe 8. A sealing plate 9, adapted to the top of the testing chamber 2, is fixedly connected to the bottom of the testing pipe 8. A clamping assembly 13 is fixedly connected to the bottom of the sealing plate 9, and the clamping assembly 13 is used to detachably connect the top of the filter bag to the testing pipe 8. The testing chamber 2 contains a testing device body 12 for testing the filtration effect of the dust collector filter bag. This configuration allows the testing pipe 8 and the clamping assembly 13 to be raised and lowered as a whole by sliding the mounting block 31, facilitating the quick removal of the entire upper device to replace the filter bag after completing a test. This provides a structural basis for subsequent continuous testing and solves the efficiency bottleneck problem in the disassembly and replacement process.

[0027] Secondly, the clamping assembly 13 includes a limiting rod 132 fixedly connected to the bottom of the sealing plate 9, two arc-shaped clamping plates 131 slidably disposed on the limiting rod 132, and a bidirectional screw 134 rotatably connected to the bottom of the sealing plate 9 for driving the two arc-shaped clamping plates 131 to move relative to each other. The bottom of the sealing plate 9 is fixedly connected to a motor 133 for driving the bidirectional screw 134 to rotate. With this configuration, there is no need to manually tighten the bolts or wrench. Only by starting the motor 133, the two arc-shaped clamping plates 131 can be quickly driven to move synchronously towards or away from each other through the bidirectional screw 134. This greatly simplifies and accelerates the clamping and disassembly process of the filter bag, and significantly improves the filter bag replacement efficiency.

[0028] Furthermore, the threads at both ends of the bidirectional screw 134 are reversed, and both ends of the bidirectional screw 134 are connected to a threaded sleeve 135 via a ball screw pair thread. The two threaded sleeves 135 are respectively fixedly connected to two arc-shaped clamping plates 131. This arrangement ensures the precise synchronization and smoothness of the movement of the two arc-shaped clamping plates 131, making the clamping action stable and reliable, and the force evenly distributed. This reduces the risk of local damage to the filter bag that the clamping force may cause, improves the transmission efficiency, reduces the driving resistance, extends the service life of the mechanism, and enhances its reliability.

[0029] Specifically, a rod 10 is fixedly connected to the sealing plate 9, and a slot 11 that matches the size of the rod 10 is provided on the top of the test chamber 2. This setting ensures that the sealing plate 9 can be accurately positioned on the sealing surface of the top of the test chamber 2 each time, ensuring the sealing between the two and effectively preventing the leakage of dust-containing gas, thereby ensuring the consistency of the test environment and the accuracy of the results. At the same time, this guide also makes the overall operation simpler and smoother.

[0030] The detection pipeline 8 is provided with an air inlet 81 and an air outlet 82 at both ends. The air inlet 81 is fixedly connected to the mounting block 31, and a fan 7 is fixedly connected inside the mounting block 31. The air outlet 82 is located at the bottom of the sealing plate 9. The air outlet 82 is used to fit the filter bag and to clamp the filter bag with the clamping assembly 13. This setting simplifies the external air path connection, reduces the resistance loss caused by the detour of the pipeline, improves the airflow stability, and makes the entire detection pipeline 8 more compact and efficient.

[0031] Furthermore, an electric push rod 6 is fixedly connected to the workbench 1. The extended end of the electric push rod 6 is fixedly connected to the bottom of the mounting block 31, which realizes the rapid, labor-saving and stable up and down movement of the detection pipe 8, sealing plate 9 and clamping assembly 13 relative to the detection chamber 2. This replaces the cumbersome steps of manual handling or manual lifting and lowering, which greatly shortens the time required for filter bag replacement. It is a key actuator for improving testing efficiency and ease of operation.

[0032] In addition, a slider 4 is fixedly connected to the mounting block 31, and a groove 5 that matches the size of the slider 4 is provided on the mounting plate 3. This setting ensures the linearity and stability of the device's movement during lifting and lowering, and prevents shaking or deviation. This not only helps protect the precision detection device inside the equipment, but also ensures the positioning accuracy of the final sealing plate 9 and the detection chamber 2.

[0033] Working principle:

[0034] When the filter bag of the dust collector filter bag testing device needs to be replaced, the electric push rod 6 is activated to drive the mounting block 31 to slide upward along the slide groove 5 on the mounting plate 3, which drives the detection pipe 8, sealing plate 9 and clamping assembly 13 to be lifted as a whole, so that the sealing plate 9 is separated from the detection chamber 2. Then the motor 133 drives the bidirectional screw 134 to rotate, which pushes the two end screw sleeves 135 through the reverse thread to drive the two arc-shaped clamping plates 131 to move in opposite directions to loosen the old filter bag. After the old filter bag is removed, the neck of the new filter bag is put on the air outlet 82 of the detection pipe 8. The motor 133 reverses to make the arc-shaped clamping plates 131 move synchronously in opposite directions to clamp and fix the filter bag. The electric push rod 6 pushes the mounting block 31 down, and the insertion rod 10 cooperates with the slot 11 on the top of the detection chamber 2 to achieve precise positioning, so that the sealing plate 9 presses the top of the detection chamber 2 to form a seal. At this time, the fan 7 inside the mounting block 31 is started, and the outside air enters the detection pipe 8 from the air inlet 81. Dust is mixed in through the dust inlet 83 to form a simulated dust-laden airflow. The airflow penetrates the filter bag and enters the detection chamber 2. The detection device body 12 collects data such as pressure difference before and after filtration and dust concentration in real time, thereby completing the continuous automated test of the filtration effect of the filter bag. The whole process replaces manual operation with mechanical linkage, which greatly shortens the filter bag replacement and sealing positioning time.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
