Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and specifically relates to an air purification filter element performance analysis and detection device. Background Art

[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, sterile 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, which will accelerate 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 and are widely used in families for indoor air purification to ensure people's physical health.

[0003] Currently, product testing is required when using and producing air filter elements on the market. The filtration effect and service performance of air purification filter elements are important items for testing. When analyzing and detecting air filter elements at present, the purification efficiency of air filter elements cannot be comprehensively detected well. After the air filter elements are recycled and cleaned, the service performance of the air filter elements cannot be detected well. Different air filter elements on the market have different specifications, and different testing instruments and equipment consume testing costs. Summary of the Invention

[0006] Preferably, balance rods are arranged on both the front and rear sides of the electric slide rail, the balance rods are fixedly connected inside the chute, and the balance rods slidably penetrate through the front and rear ends of the bottom of the sliding plate.

[0007] Preferably, the upper and lower ends of the side of the fixing plate close to the sliding plate are fixedly connected to the driving ends of electric push rods, and the electric push rods are fixedly connected to the upper and lower ends of the middle part of one side of the sliding plate.

[0008] Preferably, the rubber cylinder is communicated with the outer periphery of one side of the hose through air holes, and a sealing ring is arranged between the sliding rod and the sliding plate.

[0009] Preferably, a protective cylinder is fixedly connected to the outer side of the middle part of the side of the mounting plate close to the sliding plate, an air filter element is arranged in the middle of the protective cylinder, an image sensor is arranged on one side of the top wall of the protective cylinder, and a sealing gasket is fixedly connected to the outer periphery of the middle part of the side of the sliding plate close to the mounting plate.

[0010] Preferably, air cylinders are fixedly connected to both the upper and lower parts of the side of the mounting plate away from the sliding plate, pistons are fixedly connected to the driving ends of the air cylinders on the side close to each other, the pistons are slidably arranged inside air cylinders, and the air cylinders are fixedly connected to both sides of the middle part of the side of the mounting plate away from the sliding plate.

[0011] Preferably, the rubber balls are communicated with the side of the air cylinder close to each other through through holes, and the through holes penetrate through both sides of the middle part inside the cylinder.

[0012] Preferably, a differential pressure gauge is fixedly connected to the front side of the top end of the frame away from the sliding plate. One side of the differential pressure gauge is communicated with the inner middle part of the air filter element through a connecting pipe, and the connecting pipe sequentially penetrates through the middle parts of the cylinder and the support rod. The other side of the differential pressure gauge is communicated with one side of the air outlet through a connecting pipe. The fixed end of the air outlet penetrates through one side of the bottom end of the protective cylinder, and a dust sensor is arranged on the other side of the inner wall of the air outlet.

[0013] Working principle: When the air purification filter element performance analysis and detection device is in use, first, the cylinder contracts to make the piston move to both sides in the middle part of the air cylinder, so that the air cylinder sucks the air inside the rubber ball through the through hole, realizing the contraction of the rubber ball. At this time, one end of the air filter element is inserted into the outer periphery of the rubber ball. The cylinder works and pushes through the piston in the air cylinder, making the rubber ball expand to seal one end of the air filter element. Then, the electric push rod contracts, making the sliding rod slide in the sliding plate, realizing that the conical column abuts against the other end of the air filter element. Then, the electric slide rail slides to make the sliding plate drive the sealing gasket to abut against one end of the protective cylinder. At the same time, the electric push rod cooperates with the movement of the electric slide rail, realizing that the sliding rod firmly abuts against one end of the air filter element through the conical column. When the electric push rod and the electric slide rail are used in combination, the image sensor can observe whether the air filter element is tilted to ensure the correct installation of the air filter element. After the installation is completed, close the valve at the bottom of the dust test chamber. The fan works and passes air into the protective cylinder through the hose. The air flows through the air filter element and disperses into the protective cylinder. Then, the air flows out through the air outlet at the bottom of the protective cylinder. When flowing out, the differential pressure gauge can detect the air permeability of the air filter element through the pressure difference inside the air filter element and the pressure difference at the bottom of the protective cylinder, can obtain the air permeability of the air filter element, and can accurately judge the quality performance of the air filter element. By driving the piston inside the air cylinder through the cylinder, the air inside the air cylinder enters the rubber ball through the through hole inside the cylinder, realizing the expansion of the rubber ball. At the same time, the air filter element is blocked by the conical column, and different air filter elements can be clamped. The circular air filter element is clamped at both ends, realizing that the device can adapt to air filter elements of different sizes. When the fan works, open the valve at the bottom of the dust test chamber, so that when the hose inputs air into the air filter element, particulate dust can enter the air filter element. Then, the air filter element can block the dust. Combining the dust sensor inside the air outlet at the bottom of the protective cylinder can detect the air coming out of the protective cylinder. The dust sensor gives the concentration of the dust test, which can measure the quality of the air filtered by the air filter element and realize the accurate test of the performance of the air filter element, ensuring the effect of the air filter element.

[0014] The present invention provides an air purification filter element performance analysis and detection device. It has the following beneficial effects:

[0015] 1. In the present invention, the fan operates to introduce air into the casing through a hose. The air passes through the air filter element and diffuses into the casing. Then, the air flows out through the air outlet at the bottom of the casing. When flowing out, the differential pressure gauge can detect the air permeability of the air filter element through the pressure difference inside the air filter element and the pressure difference at the bottom of the casing, enabling the acquisition of the air permeability of the air filter element and accurately determining the quality performance of the air filter element.

[0016] 2. In the present invention, the cylinder drives the piston inside the air cylinder, enabling the air inside the air cylinder to enter the rubber ball through the through hole in the cylinder, causing the rubber ball to expand. At the same time, the air filter element is blocked by the conical column. Meanwhile, in combination with the sliding of the sliding plate, the electric push rod enables the conical column to slide through the sliding rod, capable of clamping different air filter elements. The circular air filter element is clamped at both ends, enabling the device to adapt to air filter elements of different sizes. Air filter elements of different lengths and different inner diameters can be detected, ensuring the wide application range of the device.

[0017] 3. In the present invention, when the valve at the bottom of the dust test chamber is opened, a negative pressure is generated in the dust test chamber when the hose inputs air into the air filter element, enabling particulate dust to enter the air filter element through the hose. Then, the air filter element can block the dust, and the dust sensor in the air outlet at the bottom of the casing can detect the air coming out of the casing, realizing the accurate test of the dust filtering performance of the air filter element and ensuring the effect of the air filter element.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment:

[0025] Such as Figures 1-4As shown in the figure, an air purification filter element performance analysis and detection device provided by an embodiment of the present invention includes a frame 2. The middle part of one side of the top of the frame 2 is fixedly connected to the bottom end of the mounting plate 3. The middle part of the other side of the top of the frame 2 is provided with a chute 32. The middle part of the chute 32 is provided with an electric slide rail 33. The top end of the electric slide rail 33 is slidably arranged at the middle part of the bottom end of the sliding plate 10. A slide bar 17 is slidably arranged in the middle part of the sliding plate 10. One end of the slide bar 17 close to the mounting plate 3 is fixedly connected to a conical column 21. A rubber cylinder 8 is arranged on the outer periphery of the conical column 21. One end of the slide bar 17 far from the mounting plate 3 is fixedly connected to a fixing plate 14. When the air cylinder 31 contracts, the piston 28 moves towards both sides in the middle part of the air cylinder 29, so that the air cylinder 29 sucks the air inside the rubber ball 25 through the through hole 27, realizing the contraction of the rubber ball 25. At this time, one end of the air filter element 22 is inserted into the outer periphery of the rubber ball 25. The air cylinder 31 works and pushes through the piston 28 in the air cylinder 29, so that the rubber ball 25 expands to seal one end of the air filter element 22. Then the electric push rod 11 contracts, so that the slide bar 17 slides in the sliding plate 10, realizing that the conical column 21 abuts against the other end of the air filter element 22. Then the electric slide rail 33 slides to make the sliding plate 10 drive the sealing pad 19 to abut against one end of the protection cylinder 6. At the same time, the electric push rod 11 cooperates with the movement of the electric slide rail 33, realizing that the slide bar 17 firmly abuts against one end of the air filter element 22 through the conical column 21. When the electric push rod 11 and the electric slide rail 33 are used in cooperation, it can be observed through the image sensor 20 whether the air filter element 22 is tilted, ensuring the correct installation of the air filter element 22. The upper part of the side of the fixing plate 14 far from the sliding plate 10 is fixedly connected to a dust test chamber 16. The bottom end of the dust test chamber 16 is connected to a three-way valve 15 through a hose 13. A valve is installed on the hose 13 between the dust test chamber 16 and the three-way valve 15. One side of the three-way valve 15 is communicated with the middle part of the air filter element 22 through a hose 13, and the hose 13 passes through the middle parts of the conical column 21 and the slide bar 17 at one time. The valve at the bottom of the dust test chamber 16 is closed. The fan 12 works and passes air into the protection cylinder 6 through the hose 13. The air passes through the air filter element 22 and diffuses into the protection cylinder 6. Then the air flows out through the air outlet 4 at the bottom of the protection cylinder 6. When flowing out, the differential pressure gauge 1 can detect the air permeability of the air filter element 22 through the pressure difference inside the air filter element 22 and the pressure difference at the bottom of the protection cylinder 6, can obtain the air permeability of the air filter element 22, and can accurately judge the quality performance of the air filter element 22. The other side of the three-way valve 15 is communicated with the air outlet 4 of the fan 12 through a hose 13. The fan 12 is fixedly connected to the top of the frame 2. A cylinder 26 penetrates through the middle part of the mounting plate 3. The middle part of the side of the cylinder 26 close to the sliding plate 10 is fixedly connected to a top plate 23 through a support rod 24. The outer periphery between the top plate 23 and the cylinder 26 is fixedly connected through a rubber ball 25. The rubber ball 25 can adapt to air filter elements 22 with different inner diameters, ensuring that the air filter element 22 is stably clamped.

[0026] Balancing rods 7 are provided on both the front and rear sides of the electric slide rail 33. The balancing rods 7 are fixedly connected inside the sliding grooves 32. The balancing rods 7 all slide through the front and rear ends of the bottom of the sliding plate 10. When the sliding plate 10 cooperates with the electric push rod 11 to clamp the air filter element, the electric slide rail 33 serves as a driving source to enable the sliding plate 10 to slide within the sliding groove 32. When the electric push rod 11 and the sliding plate 10 slide, corresponding stroke debugging can be carried out in combination with the programs in the prior art, which can ensure effective combination with each other without clamping and distorting the air filter element 22. The programs for their mutual cooperation are prior art and will not be elaborated in detail here.

[0027] The upper and lower ends of the side of the fixed plate 14 close to the sliding plate 10 are fixedly connected to the driving ends of the electric push rods 11. The electric push rods 11 are fixedly connected to the upper and lower ends of the middle part of one side of the sliding plate 10. The electric push rods 11 can drive the conical column 21 to move through the sliding rods 17, ensuring the flexible and efficient driving of the conical column 21.

[0028] The rubber cylinder 8 is connected to the outer periphery of one side of the hose 13 through the air hole 9. A sealing ring 18 is provided between the sliding rod 17 and the sliding plate 10. The sealing ring 18 can ensure the sealed connection between the protection cylinder 6 and the sliding plate 10, ensuring the effectiveness of the air filter element 22 test. A rubber cylinder 8 is provided outside the conical column 21. During operation, while the air volume of the blower 12 can blow towards the air filter element 22 through the hose 13, it is ensured that the air in the hose 13 inside the conical column 21 flows into the rubber cylinder 8 through the air hole 9. In this way, it can be ensured that the rubber cylinder 8 outside the conical column 21 can always squeeze the air filter element 22, ensuring the effectiveness and the sealing of both ends during the air filter element 22 test.

[0029] A protection cylinder 6 is fixedly connected to the outer middle part of the side of the mounting plate 3 close to the sliding plate 10. An air filter element 22 is provided in the middle of the protection cylinder 6. An image sensor 20 is provided on one side of the top wall of the protection cylinder 6. A sealing gasket 19 is fixedly connected to the outer periphery of the middle part of the side of the sliding plate 10 close to the mounting plate 3. The image sensor 20 can be connected to the existing control system. At the same time, the image sensor 20 is similar to the current monitoring probe, and the prior art will not be elaborated.

[0030] Cylinders 31 are fixedly connected to the upper and lower parts of the side of the mounting plate 3 away from the sliding plate 10. The driving ends of the cylinders 31 on the closer side are fixedly connected to pistons 28. The pistons 28 are all slidably arranged inside the air cylinders 29. The air cylinders 29 are fixedly connected to both sides of the middle part of the side of the mounting plate 3 away from the sliding plate 10.

[0031] Inside the rubber ball 25, there are through holes 27 that are all connected to the side close to the air cylinder 29. The through holes 27 penetrate through both sides of the middle part inside the cylinder 26. The air cylinder 31 drives the piston 28 inside the air cylinder 29, so that the air inside the air cylinder 29 enters the rubber ball 25 through the through holes 27 inside the cylinder 26, realizing the expansion of the rubber ball 25. At the same time, the air filter element 22 is blocked by the conical column 21, and different air filter elements 22 can be clamped. The circular air filter element 22 is clamped at both ends, enabling the device to adapt to air filter elements 22 of different sizes.

[0032] On the front side of the top end of the frame 2 away from one end of the sliding plate 10, a differential pressure gauge 1 is fixedly connected. One side of the differential pressure gauge 1 is connected to the middle part inside the air filter element 22 through a connecting pipe 30, and the connecting pipe 30 sequentially penetrates through the middle parts of the cylinder 26 and the support rod 24. The other side of the differential pressure gauge 1 is connected to one side of the air outlet 4 through a connecting pipe 30. The fixed end of the air outlet 4 penetrates through one side of the bottom end of the protection cylinder 6. On the other side of the inner wall of the air outlet 4, a dust sensor 5 is arranged. When the fan 12 is working, the valve at the bottom of the dust test chamber 16 is opened, so that when the hose 13 inputs air into the air filter element 22, particulate dust can enter the air filter element 22. Then the air filter element 22 can block the dust. Combined with the dust sensor 5 in the air outlet 4 at the bottom of the protection cylinder 6, the air coming out of the protection cylinder 6 can be detected. The dust sensor 5 gives the concentration of the dust test, which can measure the quality of the air filtered by the air filter element 22, realizing the accurate test of the performance of the air filter element 22 and ensuring the effect of the air filter element 22.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
