Description

Technical Field

[0001] This utility model relates to the field of test platform technology, and in particular to an air filter filtration performance test platform. Background Technology

[0002] Air filters are air filtration devices, generally used in cleanrooms, clean factories, laboratories, and clean rooms, or for dust prevention in electronic, mechanical, and communication equipment. There are five types: pre-filters, medium-efficiency filters, high-medium efficiency filters, sub-high efficiency filters, and high-efficiency filters. Each type has different standards and performance levels. When air filters are manufactured, their filtration performance during operation needs to be determined.

[0003] Currently, Chinese patent CN220983056U discloses an air filter performance testing platform, relating to the field of air filter technology. This utility model includes a support box, a connecting plate, a movable cylinder, and a bottom shell. The connecting plate is positioned above the support box, and a connecting rod is fixed to the center of the bottom of the connecting plate. The connecting rod is movably connected to the top of the support box, and a connecting piston is fixed to the bottom end of the connecting rod. The connecting piston is movably connected inside the support box. The bottom shell is positioned below the support box, and a timer is fixed to one side of the bottom shell. The movable cylinder is fixedly connected to the rear of the top surface of the bottom shell.

[0004] However, the above-mentioned device is difficult to measure the amount of dust in the air during use, making it impossible for staff to grasp the changes in the amount of dust in the air, and making it difficult to test the dust filtration performance of the filter, resulting in poor practicality. Utility Model Content

[0005] The purpose of this invention is to provide an air filter performance testing platform to solve the above-mentioned problems. By setting an electric hydraulic rod, gas can flow inside the second test tube and be filtered by the filter. The laser dust detector can measure the amount of air dust before and after filtration, thus solving the problems mentioned in the background art.

[0006] To address the above problems, this utility model provides a technical solution:

[0007] An air filter filtration performance testing platform includes a testing platform body and a filter installed on the testing platform body. The testing platform body includes a first test cylinder and a second test cylinder, with the filter located in front of the first and second test cylinders. A first test tube connected to the top of the first test cylinder is fixedly connected to the top of the first test cylinder, and a second test tube connected to the bottom of the second test cylinder is fixedly connected to the bottom of the second test cylinder. Each of the first and second test cylinders has an installation port on one outer wall. A laser dust detector is fixedly connected to one outer wall of each of the first and second test cylinders. The detection head of the first and second test cylinders is located inside the test cylinders, enabling the detection of the filter's dust filtration performance and improving the practicality of the equipment.

[0008] As a preferred embodiment of this utility model, the inner walls of the opposite sides of the first test cylinder and the second test cylinder are both inclined. The higher ends of the inclined inner walls of the first test cylinder and the second test cylinder face the first test tube and the second test tube respectively. The inclined arrangement can prevent dust from adhering to the inclined surfaces of the first test cylinder and the second test cylinder, and can make the dust rise stably and be measured.

[0009] As a preferred embodiment of this utility model, a connecting frame is fixedly connected to the top outer wall of the first test tube, and an electric hydraulic rod is fixedly connected to the bottom inner wall of the connecting frame. A pressure plate is fixedly connected to the bottom of the piston rod of the electric hydraulic rod. The pressure plate and the inner wall of the first test tube form a sliding fit. The pressure plate can be moved by the piston rod of the electric hydraulic rod. The movement of the pressure plate can transport gas through the second test tube to the first test tube.

[0010] As a preferred embodiment of this utility model, both outer walls of the first and second test cylinders are provided with connecting plates. One side of the connecting plate is provided with a positioning port corresponding to the filter mounting hole. The top of the connecting plate is provided with a connecting port. A connecting rod is slidably connected to the inner wall of the connecting port. The connecting plate can slide on the surface of the connecting rod, and the position of the connecting plate can be adjusted to suit filters of different thicknesses.

[0011] In a preferred embodiment of this utility model, a positioning plate is fixedly connected to one side of the connecting rod. The outer walls of the first and second test cylinders are each provided with a positioning groove corresponding to the connecting rod. A positioning spring is fixedly connected to the inner wall of the positioning groove. The positioning spring is fixedly connected to the connecting rod, and a sliding fit is formed between the connecting rod and the inner wall of the positioning groove. The positioning spring can apply a pulling force to the connecting rod, allowing the connecting rod to contact or separate from the inner wall of the positioning groove.

[0012] As a preferred embodiment of this utility model, a sealing gasket is fixedly connected to the opposite side of the first test cylinder and the second test cylinder. The sealing gasket is made of rubber and is in contact with the filter. The sealing gasket reduces the gap between the filter and the first and second test cylinders, thus preventing gas leakage.

[0013] The beneficial effects of this utility model are: by setting an electric hydraulic rod, gas can flow inside the second test tube and be filtered by the filter. The laser dust detector can measure the amount of air dust before and after filtration, and can detect the dust filtration performance of the filter. Therefore, it can improve the practicality of the equipment. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Example

[0022] Please see Figures 1-4This utility model provides a technical solution: an air filter filtration performance testing platform, including a testing platform body and a filter installed on the testing platform body. The testing platform body includes a first testing cylinder 1 and a second testing cylinder 3. The filter is located in front of the first testing cylinder 1 and the second testing cylinder 3. A first testing tube 2, which is connected to the top of the first testing cylinder 1, is fixedly connected to the top of the first testing cylinder 1. A second testing tube 4, which is connected to the bottom of the second testing cylinder 3, is fixedly connected to the bottom of the second testing cylinder 3. An installation port 5 is opened on one side of the outer wall of both the first testing tube 2 and the second testing tube 4. A laser dust detector 6 is fixedly connected to one side of the outer wall of both the first testing tube 2 and the second testing tube 4. The detection heads of the first testing tube 2 and the second testing tube 4 are located inside the testing tube.

[0023] See Figure 2 The inner walls of the opposite sides of the first test cylinder 1 and the second test cylinder 3 are both inclined. The higher ends of the inclined inner walls of the first test cylinder 1 and the second test cylinder 3 face the first test tube 2 and the second test tube 4, respectively. By being inclined, dust can be prevented from adhering to the inclined surfaces of the first test cylinder 1 and the second test cylinder 3, so that the dust can rise stably and be measured.

[0024] See Figure 1-3 A connecting frame 7 is fixedly connected to the top outer wall of the first test tube 1, and an electric hydraulic rod 8 is fixedly connected to the bottom inner wall of the connecting frame 7. A pressure plate 18 is fixedly connected to the bottom of the piston rod of the electric hydraulic rod 8. The pressure plate 18 and the inner wall of the first test tube 2 form a sliding fit. The pressure plate 18 can move under the movement of the piston rod of the electric hydraulic rod 8. The movement of the pressure plate 18 can transport gas through the second test tube 4 to the first test tube 2.

[0025] See Figure 1 , Figure 2 and Figure 4 Both sides of the outer walls of the first test cylinder 1 and the second test cylinder 3 are provided with connecting plates 9. One side of the connecting plate 9 is provided with a positioning port 16 corresponding to the filter mounting hole. The top of the connecting plate 9 is provided with a connecting port 10. The inner wall of the connecting port 10 is slidably connected to a connecting rod 11. The connecting plate 9 can slide on the surface of the connecting rod 11, and the position of the connecting plate 9 can be adjusted to suit filters of different thicknesses.

[0026] See Figure 1 , Figure 2 and Figure 4A positioning plate 12 is fixedly connected to one side of the connecting rod 11. The outer walls of the first test cylinder 1 and the second test cylinder 3 are provided with positioning grooves 13 that correspond one-to-one with the connecting rod 11. A positioning spring 14 is fixedly connected to the inner wall of the positioning groove 13. The positioning spring 14 is fixedly connected to the connecting rod 11. A sliding fit is formed between the connecting rod 11 and the inner wall of the positioning groove 13. The positioning spring 14 can apply a pulling force to the connecting rod 11, so that the connecting rod 11 can contact or separate from the inner wall of the positioning groove 13.

[0027] See Figure 2 and Figure 4 A sealing gasket 15 is fixedly connected to the opposite side of the first test cylinder 1 and the second test cylinder 3. The sealing gasket 15 is made of rubber and is in contact with the filter. The sealing gasket 15 can reduce the gap between the filter and the first test cylinder 1 and the second test cylinder 3, thus preventing gas leakage.

[0028] In summary: When using this device, the filter is installed between the first test cylinder 1 and the second test cylinder 3. First, the connecting rod 11 is pulled to separate from the inner wall of the positioning groove 13. Then, after the filter is installed in a suitable position, the connecting rod 11 is pulled to make it fit against the outer wall of the filter housing. Then, the connecting rod 11 is made vertical and slid into the positioning groove 13. The bolt is rotated to fix the connecting rod 11 to the outer wall of the filter housing. Activating the electric hydraulic rod 8 allows gas to flow in the second test tube 4 and pass through the filter. The laser dust detector 6 can measure the amount of air dust before and after filtration, respectively, and can detect the dust filtration performance of the filter. Therefore, the practicality of the equipment can be improved.
