Description

Technical Field

[0001] The present invention relates to the technical field of air permeability detection, and in particular to an air permeability detection device for dust removal filter materials. Background Art

[0002] Air permeability testing equipment is a specialized instrument used to measure the gas permeability of materials. By simulating different environmental conditions, it accurately measures parameters such as the rate and resistance of gas permeation through the material to assess the material's ability to allow gas to pass through. Under a certain pressure differential, gas is passed through the sample, and the amount of gas that passes through the sample within a specified time is measured, thereby calculating the material's air permeability. This method is relatively simple to operate and is suitable for testing the air permeability of most common filter media.

[0003] Existing dust removal filter media air permeability testing equipment uses the constant pressure method and the constant flow method. The constant pressure method measures the air flow rate vertically passing through the filter media sample within a certain period of time under specified pressure differential conditions to calculate the air permeability. The constant flow method measures the pressure difference on both sides of the filter media while maintaining a constant air flow to evaluate the air permeability characteristics. However, because existing dust removal filter media air permeability testing equipment can only perform a single air permeability test on the material, it is unable to simultaneously test the air permeability of the dust removal filter media in both the dust-free and dust-containing states. As a result, it is unable to test the air permeability of the dust removal filter media under various conditions. In view of the above technical defects, a solution is now proposed.

[0020] In the embodiment of the present invention, when it is necessary to use the dust removal filter material air permeability detection equipment, the object to be tested is placed on the top surface of the test table 501. After the placement is completed, the air cylinder 4 and the electric telescopic rod 5 are started. When the electric telescopic rod 5 is started, the end thereof will push the test table 501 to move upward, and eventually the top of the test table 501 and the bottom of the first detection tube 102 will contact each other. When the two are in contact with each other, the test table 501 and the first detection tube 102 will squeeze the test object so that the test object is fixed therebetween. When the air pump 105 is started, the gas will be input to the inner wall of the gas supply ring 106 through the hose.

At this time, the gas will come into contact with the test object squeezed by the test table 501 and the first detection tube 102.

Due to the pressure difference on both sides of the test object, the test gas will penetrate from the high-pressure cavity through the material to the low-pressure cavity.

At this time, the gas flow meter 504 detects and calculates the permeability of the low-pressure cavity, thereby obtaining the air permeability performance of the object, thereby realizing the air permeability test of the object.

[0021] Reference Figures 1-11Specifically, the dust simulation component includes a docking groove 2, which is opened on the top surface of the bracket 101, and a dust tank 201 is movably inserted into the inner wall of the docking groove 2, and a collection plate 202 is movably inserted into the inner wall of the dust tube. A row pipe 203 is fixedly installed on the top surface of the detection tube, and the row pipe 203 is provided with four circular arrays distributed on the top surface of the detection tube. A rotating tube 204 is movably and rotatably installed on the inner wall of the row pipe 203, and a rotating tube 204 is correspondingly distributed on the inner wall of each row pipe 203. A spiral rod 205 is fixedly installed on the inner wall of the rotating tube 204, and one end of the spiral rod 205 extends from the collection plate 202 to the interior of the dust tank 201. The outer surface of the spiral rod 205 is provided with meshing teeth 206, and an ultrasonic vibrating plate 207 is installed on the inner wall of the first detection tube 102. The humidity simulation component is installed on the inner wall of the dust tank 201, and the driving component includes a cylinder 4. Connecting plates 401 are distributed correspondingly on the bottom end surfaces of the two cylinders 4. Cylinder 4 is provided with two equally spaced upper surfaces of the inner wall of bracket 101. Cylinder 4 is fixedly mounted on the bottom end surface of the inner wall of bracket 101. Connecting plates 401 are fixedly mounted on the bottom end surface of the inner wall of bracket 101. The two connecting plates 401 are fixedly connected to the second detection tube 104. A positioning ring 402 is fixedly mounted on the top surface of bracket 101. A bearing 403 is fixedly mounted on the inner wall of positioning ring 402. A transmission gear 404 is movably and rotatably mounted on the inner wall of bearing 403. The transmission gear 404 is engaged with four meshing teeth 206. A driving motor 405 is mounted on the bottom end surface of the inner wall of equipment housing 1. A crawler disc 406 is fixedly mounted on the bottom output end of driving motor 405. A transmission crawler 407 for mutual transmission with transmission gear 404 is mounted on the outer surface of crawler disc 406.

[0022] In the embodiment of the present invention, when the air permeability test is completed and the dust permeability of the material needs to be simulated, the control cylinder 4 is retracted to drive the second detection tube 104 to move upward so that the second detection tube 104 is no longer located on the inner wall of the airtight groove 103. When the second detection tube 104 is reset, the drive motor 405 is started. When the drive motor 405 is driven, it will drive the track disc 406 installed at its output end to rotate. The outer surface of the track disc 406 is installed with a transmission track 407. Therefore, when the track disc 406 rotates, the transmission track 407 will drive the transmission gear 404 on the inner wall of the bearing 403 to rotate, and the transmission gear 404 is engaged with the meshing teeth 206 set on the outer surface of the rotating tube 204. Therefore, when the transmission gear 404 rotates, it will drive the rotating tube 204 to rotate on the inner wall of the discharge pipe 203. The spiral rod 205 is installed on the inner wall of the discharge pipe 203, and the spiral rod 205 extends from the inner wall of the collecting plate 202 to the dust tank 201 filled with test dust particles. When the spiral rod 205 rotates in the dust tank 201, a certain amount of dust particles will be transported into the inner wall of the rotating tube 204 through rotation, and finally the dust particles will be discharged from the end of the discharge pipe 203, and fall on the ultrasonic vibration plate 207. At this time, the activated ultrasonic vibration plate 207 will shake the fallen dust particles apart and make them evenly distributed on the inner wall of the first detection tube 102. At this time, since the air pump 105 is not turned off, there is air output by the air pump 105 inside the first detection tube 102. At this time, the shaken dust particles will fall evenly on the top surface of the test object along the airflow, realizing dust simulation of the material.

[0023] Reference Figure 1 - Figure 11 Specifically, the humidity simulation component includes a water storage bottle 3, which is movably and rotatably connected to the positioning tube 302 by a thread, and is movably and rotatably connected to the positioning tube 302 by a thread. The water storage bottle 3 is movably inserted into the inner wall of the dust tank 201, and a water-absorbing sponge rod 301 is installed on the bottom surface of the water storage bottle 3, and the water-absorbing sponge rod 301 is movably inserted into the inner wall of the positioning tube 302, and the bottom surface of the water-absorbing sponge rod 301 is in movably contact with the top surface of the atomizing piece 303, and the inner wall of the second detection tube 104 is fixedly installed with the positioning tube 302, and the bottom surface of the positioning tube 302 is installed with the atomizing piece 303.

[0024] In the embodiment of the present invention, when a moisture and air permeability test is required, the water storage bottle 3 is filled with water and inserted into the inner wall of the dust tank 201. The dust tank 201 and the positioning tube 302 are connected to each other through threads. During the test, the atomizing sheet 303 is started. Since a water-absorbing sponge rod 301 is installed on the bottom surface of the water storage bottle 3, and the bottom surface of the water-absorbing sponge rod 301 contacts the atomizing sheet 303, the water-absorbing sponge rod 301 absorbs water from the water storage bottle 3 and keeps it moist. When the atomizing sheet 303 is started, the moisture in the water-absorbing sponge rod 301 will be quickly absorbed. Through the high-frequency vibration of the atomizing sheet 303, the moisture in the water-absorbing sponge rod 301 will be decomposed into tiny water mist particles, and the water mist particles will be sprayed out from the bottom of the atomizing sheet 303. Since the air pump 105 is not turned off at this time, there is air output by the air pump 105 inside the first detection tube 102. At this time, the water mist sprayed by the atomizing sheet 303 will fall evenly on the top surface of the test object along the air flow, realizing the humidity simulation of the material.

[0025] Specific usage process: When the dust filter material air permeability test equipment is needed, the object to be tested is placed on the top surface of the test table 501. After the object is placed, the cylinder 4 and the electric telescopic rod 5 are started. When the electric telescopic rod 5 is started, the end of the electric telescopic rod 5 pushes the test table 501 upward, and finally the top of the test table 501 contacts the bottom of the first detection tube 102. When the two contact each other, the test table 501 and the first detection tube 102 squeeze the test object so that the test object is fixed between the two. When the cylinder 4 is started, its end will extend, and the connecting plate 401 on the bottom surface of the cylinder 4 is fixedly connected to the outer surface of the second detection tube 104. Therefore, when the cylinder 4 is started, the second detection tube 104 will move downward along with the cylinder 4 and the connecting plate 401. The second detection tube 104 is on the inner wall of the first detection tube 102. At this time, the second detection tube 104 will slide downward along the inner wall of the first detection tube 102. When the cylinder 4 is fully extended, the bottom end of the second detection tube 104 will be inserted into the inner wall of the airtight groove 103, so that the second detection tube 104 can be inserted into the inner wall of the airtight groove 103. The first detection tube 102 and the second detection tube 104 are connected to each other to improve the airtightness. At this time, the air pump 105 is started. When the air pump 105 is started, the gas is input to the inner wall of the gas supply ring 106 through the hose. The gas supply ring 106 and the interior of the second detection tube 104 are connected to each other. When the air pump 105 is started, since the air pump 105 continuously outputs gas, the gas will come into contact with the test object squeezed by the test table 501 and the first detection tube 102. Since the inner wall of the first detection tube 102 continuously outputs gas, the gas at this time The principle of permeation occurs due to a pressure difference on both sides of the material, thereby forming a high-pressure cavity in the first detection tube 102, and a low-pressure cavity formed by the airtight detection slot 502 opened on the top of the test bench 501. Due to the pressure difference on both sides of the test object, the test gas will penetrate from the high-pressure cavity through the material to the low-pressure cavity. The airtight detection slot 502 is connected to the output end of the gas flow meter 504 through the connecting tube 503. At this time, the gas flow meter 504 detects and calculates the permeability of the low-pressure cavity, thereby deriving the air permeability performance of the object, thereby realizing the air permeability detection of the object.

[0026] When the air permeability test is completed and the dust permeability of the material needs to be simulated, the control cylinder 4 is retracted to drive the second detection tube 104 to move upward so that the second detection tube 104 is no longer located on the inner wall of the airtight groove 103. When the second detection tube 104 is reset, the drive motor 405 is started. When the drive motor 405 is driven, it drives the track disc 406 installed at its output end to rotate. The outer surface of the track disc 406 is installed with a transmission track 407. Therefore, when the track disc 406 rotates, the transmission track 407 drives the transmission gear 404 on the inner wall of the bearing 403 to rotate. The transmission gear 404 is engaged with the meshing teeth 206 provided on the outer surface of the rotating tube 204. Therefore, when the transmission gear 404 rotates, it drives the rotating tube 204 to rotate on the inner wall of the row tube 203. Since a spiral rod 205 is installed on the inner wall of the discharge pipe 203, the spiral rod 205 extends from the inner wall of the collecting plate 202 to the dust tank 201 filled with test dust particles. When the spiral rod 205 rotates in the dust tank 201, a certain amount of dust particles will be transported into the inner wall of the rotating tube 204 through rotation, and finally the dust particles will be discharged from the end of the discharge pipe 203 and fall on the ultrasonic vibration plate 207. At this time, the activated ultrasonic vibration plate 207 will shake the fallen dust particles apart and make them evenly distributed on the inner wall of the first detection tube 102. Since the air pump 105 is not turned off at this time, there is air output by the air pump 105 inside the first detection tube 102. At this time, the shaken dust particles will fall evenly on the top surface of the test object along the airflow, realizing dust simulation of the material.

[0027] When it is necessary to conduct a moisture and air permeability test, the water storage bottle 3 is filled with water and inserted into the inner wall of the dust tank 201. The dust tank 201 and the positioning tube 302 are connected to each other through threads. During the test, the atomizing sheet 303 is started. Since the water absorption sponge rod 301 is installed on the bottom surface of the water storage bottle 3, and the bottom surface of the water absorption sponge rod 301 contacts the atomizing sheet 303, the water absorption sponge rod 301 absorbs water from the water storage bottle 3 and keeps it moist. When the atomizing sheet 303 is started, the moisture in the water-absorbing sponge rod 301 will be quickly absorbed. Through the high-frequency vibration of the atomizing sheet 303, the moisture in the water-absorbing sponge rod 301 will be decomposed into tiny water mist particles, and the water mist particles will be sprayed out from the bottom of the atomizing sheet 303. Since the air pump 105 is not turned off at this time, there is air output by the air pump 105 inside the first detection tube 102. At this time, the water mist sprayed by the atomizing sheet 303 will fall evenly on the top surface of the test object along the air flow, realizing the humidity simulation of the material.

[0028] Humidity simulation and dust simulation can be performed simultaneously. When both are performed simultaneously, the downward-moving water mist and dust particles will simultaneously adhere to the surface of the test object. When the dust and water mist come into contact with each other, muddy water with a certain viscosity will form on the surface of the test object, thus realizing another test mode.

[0029] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
