Description

Technical Field

[0001] This application relates to the field of air purification. Specifically, it relates to a performance analysis and detection device for a cylindrical air purification filter element based on an image sensor. Background Technique

[0002] An air filter element is a filter, also known as an air filter cartridge, air cleaner, air filter, etc. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, aseptic operation rooms, and various precision operation rooms. During the operation of an engine, a large amount of air needs to be inhaled. If the air is not filtered, the dust suspended in the air will be inhaled into the cylinder, accelerating the wear of the piston group and the cylinder. Larger particles entering between the piston and the cylinder will cause serious "cylinder scoring" phenomena, which is particularly serious in dry and sandy working environments. The air cleaner is installed in front of the carburetor or the intake pipe to filter out dust and sand particles in the air, ensuring that sufficient and clean air enters the cylinder. Each type of air cleaner has its own advantages and disadvantages, but inevitably there is a contradiction between the air intake volume and the filtration efficiency. With the in-depth research on air cleaners, the requirements for air cleaners are getting higher and higher. Some new types of air cleaners have emerged, such as fiber filter element air cleaners, composite filter material air cleaners, muffler air cleaners, constant temperature air cleaners, etc., to meet the needs of engine operation. Air purifiers also use air purification filter elements, which are widely used in families for indoor air purification to ensure people's physical health.

[0003] The patent document with the publication number CN114674724A discloses a performance analysis and detection device for an air purification filter element, which relates to the field of air purification. This performance analysis and detection device for an air purification filter element includes a frame. One side of the middle part of the top of the frame is fixedly connected to the bottom end of the mounting plate. One end of the sliding rod close to the mounting plate is fixedly connected to a conical column. A rubber cylinder is arranged on the outer circumference of the conical column. The upper part of the side of the fixing plate away from the sliding plate is fixedly connected to a dust test chamber. The fan is fixedly connected to the top of the frame. A cylinder penetrates through the middle part of the mounting plate. One side of the middle part of the cylinder close to the sliding plate is fixedly connected to a top plate through a support rod. The outer circumference between the top plate and the cylinder is fixedly connected through a rubber ball. Although the above application document solves the problems of incomplete detection of existing air filter elements, the inability to detect the filter element well after cleaning, and the difficulty in detecting filter elements of different sizes, it is not convenient to put the air filter element into the protective cylinder during use, reducing the convenience of use.

A clamping block 54 is fixedly connected to the outer wall of the permanent magnet 56. The electric telescopic rod 51 drives the fixing block 52 and the magnetic conductor 53 to move downward. The magnetic conductor 53 magnetically attracts the permanent magnet 56, thereby driving the clamping block 54 to clamp the filter element. The telescopic action of the electric telescopic rod 51 realizes the automatic operation of clamping and releasing. An image sensor 57 is assembled inside the protection cylinder 21. A conical block 58 is assembled on the side of the electric skateboard 55, and a through hole is opened on the left side of the conical block 58. A blower 59 is assembled on the side of the electric skateboard 55. A connecting pipe is fixedly connected to the top of the blower 59. The connecting pipe fixedly penetrates through the electric skateboard 55 and extends to the left, and the extended end is fixedly connected to the side of the conical block 58. An image sensor 57 is assembled inside the protection cylinder 21. The balance of the air filter element is detected by the image sensor 57 for real-time monitoring of the balance state of the air filter element. The blower 59 transports the air flow to the through hole of the conical block 58 through the connecting pipe, and the air flow passes through the inside of the filter element to simulate the actual working condition.On the side of the electric skateboard 55, a dust bin 511 is assembled.

[0025] When the above device is specifically used, start the electric telescopic rod 51 to drive the fixed block 52 and the magnetizer 53 to move downward.

The electric skateboard 55 drives the protection cylinder 21 to move to the left. The electric skateboard 55 drives the moving rod 22 to move to the left. The moving rod 22 presses the first hydraulic rod 24.

A knocking block 38 is fixedly sleeved on the outer wall of the rotating rod 37. The third hydraulic rod 33 and the rack 34 inside the second hydraulic chamber 32 are driven by hydraulic pressure. The movement of the rack 34 drives the annular gear 36 to rotate, and then drives the rotating rod 37 and the knocking block 38 to perform a knocking action. The knocking block 38 is oval. The annular gear 36 meshes with the rack 34. The oval knocking block 38 can better adapt to the surface of the dust bin 511, improving the knocking effect. The meshing of the annular gear 36 and the rack 34 ensures the stability and reliability of the knocking action.

[0027] When the above device is in specific use, when the support plate 26 drives the casing 21 to close, the casing 21 drives the pressing block 31 to move backward. The pressing block 31 drives the third hydraulic rod 33 to move backward. During the process of the third hydraulic rod 33 moving backward, the pressure inside the second hydraulic chamber 32 increases, driving the rack 34 to descend. The descent of the rack 34 drives the annular gear 36 to rotate. The annular gear 36 drives the rotating rod 37 to rotate. The rotating rod 37 drives the knocking block 38 to knock on the outer wall of the dust bin 511 to shake off the condensed dust.

[0028] Embodiment 3, refer to Figures 1-7 , on the basis of Embodiment 1, the collecting device 4 includes a trigger rod 41. The trigger rod 41 is fixedly connected to the front of the rack 34.

When the rack 34 moves, the trigger rod 41 drives the fourth hydraulic rod 43 to act, causing the collecting box 45 to rise and collect dust. A dust box 47 is slidably connected to the inner wall of the base 1. The output end of the valve 46 is arranged at the top of the dust box 47. The dust enters the dust box 47 through the valve 46, realizing the centralized collection and treatment of dust. The design of the dust box 47 reduces the environmental pollution caused by dust and is convenient for maintenance and cleaning at the same time.

[0029] When the above-mentioned device is in specific use, the rack 34 descends to drive the trigger rod 41 to descend. The trigger rod 41 drives the fourth hydraulic rod 43 to descend. During the descent of the fourth hydraulic rod 43, the internal pressure of the third hydraulic chamber 42 increases, driving the fifth hydraulic rod 44 to rise. The fifth hydraulic rod 44 drives the collection box 45 to rise. The collection box 45 is connected to the valve 46 through a hose on the right side. The valve 46 and the three-way valve 510 are opened, and the powder in the dust bin 511 falls. The dust is transmitted to the air filter element through the blower 59, the connecting pipe, and the conical block 58. The air filter element can block the dust. Combined with the dust sensor 514 in the dust outlet 513 at the bottom of the protective cylinder 21, the air coming out of the protective cylinder 21 can be detected. The dust sensor 514 gives the concentration of the dust test, which can measure the quality of the air filtered by the air filter element, realizing the accurate test of the performance of the air filter element and ensuring the effect of the air filter element.
