Description

Technical Field

[0001] This utility model relates to the field of filter production technology, specifically a pretreatment device for the production of high-temperature resistant filters. Background Technology

[0002] A filter typically consists of a rigid frame and a filter medium filled within it. The filter medium can be a fibrous material (such as glass fiber or synthetic fiber) or other similar materials. It is mainly used to filter coarse particles in the air, such as dust, pollen, and other larger particles. In some industrial applications, such as steel manufacturing, glass production, and ceramic firing, air filters need to operate in high-temperature environments. The air in these environments may contain high-temperature flue gas or particulate matter, so the filter must be heat-resistant to maintain its structural integrity and filtration performance, and also to improve the fire safety of the filter.

[0003] After the filter is manufactured, the filter body is pre-treated for differential pressure and filtration effect to determine the effect of the filter when it is put into use on the market. Current measuring devices are all set up individually, and it is impossible to test and process two functions on the same device. Moreover, it is difficult to test the sealing gasket at the filter frame.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0007] Preferably, an electric actuator is rotatably mounted on one side of the guide plate, and the other end of the electric actuator is rotatably connected to the connecting cross plate.

[0008] Preferably, a placement rack is connected to both the connecting cross plate and the worktable on the side that is close to each other, and an anti-slip sealing ring is connected to the top of the placement rack.

[0009] Preferably, a filter screen is connected to one side of both the exhaust pipe and the inner wall of the lower air intake hopper.

[0010] Preferably, there are two sets of test object fixing frames, and each set has a mounting hole at one end located inside the lower air inlet hopper.

[0011] Preferably, the side of the workbench away from the test object holder is the loading surface.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] By using a mounting rack and anti-slip sealing rings, the sealing effect on both sides of the filter frame can be guaranteed, ensuring accurate testing. The filtration efficiency and filtration differential pressure can be detected by an electronic differential pressure gauge and a particle counter, respectively. At the same time, the sealing effect at the front frame of the filter can be detected by pressing down the sealing plate, effectively improving the functionality of the testing and processing, increasing efficiency while reducing equipment consumption.

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.

[0019] Please see Figure 1-3 This utility model provides a technical solution: it includes a support leg 1, a workbench 2 connected to the top of the support leg 1, the side of the workbench 2 away from the test object fixing frame 7 is the feeding surface, the top of the workbench 2 has corresponding through holes for filter ventilation, a lower air inlet hopper 3 connected to the bottom of the workbench 2, a fan frame 4 connected to the inner side of the lower air inlet hopper 3, an air intake fan 5 connected to the top of the fan frame 4, an air intake duct 6 connected to the bottom of the lower air inlet hopper 3, a test object fixing frame 7 slidably mounted on one side of the top of the air intake duct 6, a handle 8 connected to the top of the test object fixing frame 7, and the top of the support leg 1 is connected to... A guide plate 9 is provided, and a connecting horizontal plate 10 is slidably provided at one end of the guide plate 9. An upper air outlet hopper 11 is connected to the top of the connecting horizontal plate 10. An electronic differential pressure gauge 12 and a particle counter 13 are connected to one side of the upper air outlet hopper 11 and the lower air inlet hopper 3, respectively, for detecting and comparing the values ​​before and after filtration. A connecting frame 15 is connected between the inner walls of the upper air outlet hopper 11. A cylinder 16 is connected to the top of the connecting frame 15. The output end of the cylinder 16 passes through the connecting frame 15 and is connected to a sealing plate 17. A guide rod 18 is connected to the top of the sealing plate 17. An exhaust pipe 19 is connected to the top of the upper air outlet hopper 11.

[0020] Reference Figure 1 and 2 As shown, an electric push rod 14 is rotatably mounted on one side of the guide plate 9. The other end of the electric push rod 14 is rotatably connected to the connecting horizontal plate 10. The extension and retraction of the electric push rod 14 drives the connecting horizontal plate 10 to move up and down, so as to clamp and fix the filter on the top of the workbench 2.

[0021] Reference Figure 1 and 2 As shown, a placement rack 20 is connected to both the connecting horizontal plate 10 and the worktable 2 on their respective sides. An anti-slip sealing ring 21 is connected to the top of the placement rack 20. When the filter is placed on the top of the anti-slip sealing ring 21, the edge of the filter is sealed by the anti-slip sealing ring 21 after the connecting horizontal plate 10 is pressed down, ensuring accurate detection.

[0022] Both the exhaust pipe 19 and the lower air intake hopper 3 are equipped with a filter screen 22 on one side of their inner walls. This prevents accidental debris from entering the test pipe during testing, ensuring the safety of the equipment.

[0023] There are two sets of test object holders 7, and each end located inside the lower air intake hopper 3 has an installation hole. The burning, smoky material can be stuck into the installation hole and then inserted into the lower air intake hopper 3 to facilitate more accurate testing of the filter.

[0024] The implementation principle of this application is as follows: When using this utility model, the filter is placed on top of the anti-slip sealing ring 21, and then the electric push rod 14 extends to push the connecting horizontal plate 10 down, clamping and fixing the filter on both sides through the anti-slip sealing ring 21, while ensuring the sealing effect. Then, two sets of electronic differential pressure gauges 12 and particle counters 13 are turned on, and the air intake fan 5 is started. The two sets of electronic differential pressure gauges 12 detect the pressure before and after the filter, thereby calculating the pressure difference. At the same time, particulate smoke can be introduced into the air intake hopper 3 through the test object fixing frame 7. The particle counter 13 detects the concentration of particulate matter before and after filtration. By comparing the number of particles entering the filter and the number of particles after filtration, the filtration efficiency is calculated. During the test, the cylinder 16 can extend to push the sealing plate 17 down until the sealing plate 17 covers the exposed back of the filter, and then the test continues, thereby testing whether there is a leakage at the filter frame.
