Description

Technical Field

[0001] This utility model relates to the field of air filter resistance testing technology, specifically an air filter resistance testing platform. Background Technology

[0002] Air filters are generally classified into pre-filters, medium-efficiency filters, and high-efficiency filters, and are widely used in various air purification scenarios. During the production of air filters, several technical indicators need to be strictly controlled, such as differential pressure and resistance. Therefore, it is necessary to test the air filter's air resistance and issue a corresponding test report.

[0003] Due to the limited functionality and cost of existing testing equipment, manufacturers cannot quickly simulate tests on air filters of different specifications according to testing needs. In addition, special tooling fixtures are required to clamp the air filters during assembly, which is very inconvenient and results in long testing times. Utility Model Content

[0004] The purpose of this invention is to provide an air filter resistance testing platform to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: an air filter wind resistance testing platform, including a base, a box mounted on the base, a detachable top cover on the top of the box, symmetrically arranged air inlet pipes and exhaust pipes mounted on the box, the air inlet pipes being connected to a blower, and a measurement and control system mounted on the air inlet pipes and the exhaust pipes, a partition fixed inside the box on the side near the air inlet pipe, an air guide port being opened on the partition, a lifting assembly being provided at the bottom end of the side of the partition away from the air inlet pipe, two horizontally adjustable clamping components being mounted on the lifting end of the lifting assembly, and two arc-shaped side support strips for pressing against the air filter to be tested being provided at the top of the lifting assembly.

[0006] The aforementioned components achieve the following effects: the blower blows air into the chamber through the air inlet pipe; the air flows through the air duct on the partition to the area where the air filter to be tested is installed, and then exits from the exhaust pipe; the measurement and control system detects the air resistance of the air filter; the lifting assembly can be raised and lowered, and together with the laterally self-adjustable clamping assembly and arc-shaped side support bars, it can firmly fix the air filters to be tested of different specifications; the removable top cover facilitates the insertion and removal of the air filters to be tested, enabling manufacturers to quickly simulate and test air filters of different specifications according to their testing needs at any time, and making installation and disassembly convenient, increasing the versatility of the testing platform, improving testing efficiency, and solving the problems of single-function testing equipment and inconvenient installation and disassembly leading to long testing times.

[0007] Preferably, the lifting assembly includes a base plate installed on one side of the bottom end of the partition, an electric lifting rod is installed on the base plate, a support plate for supporting the air filter is installed at the top of the electric lifting rod, and the clamping assembly is installed on the support plate.

[0008] The aforementioned components achieve the following effect: the electric lifting rod, supported by the base plate, drives the support plate to rise and fall, with the support plate supporting the air filter, thereby adjusting the height of the air filter. This allows for flexible adjustment of the height of air filters of different specifications to better match the airflow path within the chamber, improving the accuracy of the test.

[0009] Preferably, the clamping assembly includes a slot formed on the pallet, a sliding sleeve slidably installed in the slot, a clamping block fixed to the top of the sliding sleeve, a guide slope formed on one side of the top of the clamping block, a guide post slidably inserted into the bottom of the sliding sleeve and installed on the bottom of the pallet, and a spring sleeved on the end of the guide post away from the center of the pallet, which abuts against the sliding sleeve.

[0010] The effect achieved by the above components is as follows: when placing the air filter to be tested, the filter presses down on the clamping block along the guide slope, causing the sliding sleeve to slide away from the center of the tray under the guidance of the slot and guide post and compress the spring. The reaction force of the spring pushes the sliding sleeve, causing the clamping block to clamp the filter. This achieves the purpose of adaptive clamping and fixing of air filters of different widths and specifications, and is convenient to install and remove, improving the efficiency of installation and removal, and solving the problem of inconvenient installation and removal caused by the need for special tooling fixtures in the existing technology.

[0011] Preferably, the measurement and control system includes an upstream pressure measuring point and a downstream pressure measuring point respectively disposed on the intake pipe and the exhaust pipe, the upstream pressure measuring point and the downstream pressure measuring point are connected to a differential pressure sensor, and the differential pressure sensor is electrically connected to a control processing module.

[0012] The above components achieve the following effects: the upstream and downstream pressure measuring points detect the pressure upstream and downstream of the air filter, respectively; the differential pressure sensor transmits the detected pressure difference signal to the control processing module; the control processing module processes the signal, thereby achieving the purpose of accurately measuring the air filter resistance and improving the detection accuracy and automation level.

[0013] This utility model provides an improved air filter wind resistance testing platform, which has the following improvements and advantages compared with the prior art:

[0014] This invention features a lifting component that allows for height adjustment, along with a laterally adjustable clamping component and arc-shaped side support bars, which can securely fix air filters of different specifications to be tested.

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved air filter wind resistance testing platform. The technical solution of this utility model is as follows:

[0024] In embodiments of this utility model, such as Figures 1-4As shown, an air filter resistance testing platform includes a base 1, a housing 2 mounted on the base 1, a removable top cover 5 on the top of the housing 2, and symmetrically arranged air inlet pipes 3 and exhaust pipes 4 mounted on the housing 2. The air inlet pipes 3 are connected to a blower 6. A measurement and control system is installed on the air inlet pipes 3 and 4. The blower 6 blows air into the housing 2 through the air inlet pipes 3. The air flows through the air ducts 11 on the partition 7 to the area where the air filter to be tested is installed, and then exits from the exhaust pipes 4. The measurement and control system detects the air resistance of the air filter. A partition 7 is fixed on the side of the inner air intake pipe 3. An air guide port 11 is opened on the partition 7. A lifting assembly 8 is provided at the bottom of the side of the partition 7 away from the air intake pipe 3. Two horizontally adjustable clamping assemblies 9 are installed on the lifting end of the lifting assembly 8. Two arc-shaped side support bars 10 are provided at the top of the lifting assembly 8 to press against the air filter to be tested. The lifting assembly 8 can be raised and lowered. With the horizontally adjustable clamping assemblies 9 and the arc-shaped side support bars 10, air filters of different specifications can be firmly fixed. The detachable top cover 5 makes it easy to put in and take out the air filter to be tested.

[0025] In this embodiment of the invention, the lifting assembly 8 includes a base plate 81 installed on one side of the bottom of the partition 7. An electric lifting rod 82 is mounted on the base plate 81, and a support plate 83 for supporting the air filter is installed at the top of the electric lifting rod 82. A clamping assembly 9 is installed on the support plate 83. With the support of the base plate 81, the electric lifting rod 82 drives the support plate 83 to rise and fall. The support plate 83 supports the air filter, thereby adjusting the height of the air filter. This achieves the goal of flexibly adjusting the height of air filters of different specifications to better match the airflow path inside the housing 2.

[0026] In an embodiment of this utility model, the clamping assembly 9 includes a slot formed on the tray 83, a sliding sleeve 94 slidably installed in the slot, a clamping block 91 fixed on the top of the sliding sleeve 94, a guide slope 92 formed on one side of the top of the clamping block 91, a guide post 93 slidably inserted into the bottom of the sliding sleeve 94 and installed on the bottom of the tray 83, and a spring 95 that abuts against the sliding sleeve 94 is sleeved on the end of the guide post 93 away from the center of the tray 83. When the air filter to be tested is placed, the filter presses down on the clamping block 91 along the guide slope 92, so that the sliding sleeve 94 slides away from the center of the tray 83 under the guidance of the slot and the guide post 93 and compresses the spring 95. The reaction force of the spring 95 pushes the sliding sleeve 94, so that the clamping block 91 clamps the filter, thereby achieving the purpose of adaptive clamping and fixing of air filters of different widths and specifications, and convenient installation and removal.

[0027] In an embodiment of this utility model, the measurement and control system includes an upstream pressure measuring point and a downstream pressure measuring point respectively installed on the intake pipe 3 and the exhaust pipe 4. The upstream pressure measuring point and the downstream pressure measuring point are connected to a differential pressure sensor, and the differential pressure sensor is electrically connected to a control processing module. The upstream pressure measuring point and the downstream pressure measuring point detect the pressure upstream and downstream of the air filter respectively. The differential pressure sensor transmits the detected pressure difference signal to the control processing module. The control processing module processes the signal to achieve the purpose of accurately measuring the air filter resistance.

[0028] The working principle of the air filter resistance testing platform provided by this utility model is as follows:

[0029] Placement and fixing of the air filter to be tested: Open the removable top cover 5 of the top of the housing 2 and place the air filter to be tested on the support plate 83 of the lifting assembly 8; during the placement process, the filter is pressed down along the guide slope 92 of the clamping block 91 in the clamping assembly 9, so that the sliding sleeve 94 slides away from the center along the groove of the support plate 83 and the guide post 93 and compresses the spring 95. The reaction force of the spring 95 pushes the sliding sleeve 94 to reset, causing the clamping block 91 to adaptively clamp the filter. At the same time, the arc-shaped side support bar 10 at the top of the support plate 83 assists in clamping from the side; the electric lifting rod 82 of the lifting assembly 8 (installed on the base plate 81) drives the support plate 83 to rise and fall, adjusting the height of the filter to match the airflow path inside the housing 2;

[0030] Forming a detection airflow: Start the blower 6 connected to the air inlet pipe 3. Air enters the housing 2 through the air inlet pipe 3, flows directionally to the fixed air filter through the air guide port 11 on the partition 7, passes through the filter and is discharged from the exhaust pipe 4, forming a stable detection airflow channel.

[0031] Wind resistance detection and processing: In the measurement and control system, the upstream pressure measuring point of the intake pipe 3 and the downstream pressure measuring point of the exhaust pipe 4 collect pressure data of the upstream and downstream of the filter, respectively, and transmit the data to the differential pressure sensor; the differential pressure sensor sends the pressure difference signal to the control processing module, which calculates and outputs the wind resistance detection result of the air filter under test.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
