Description

Technical Field

[0001] This utility model belongs to the field of filtration-related technology, and in particular relates to a dust removal air filter element. Background Technology

[0002] An air filter element is a type of filter, also known as an air filter cartridge, air purifier, etc. It is mainly used for air filtration in engineering vehicles, automobiles, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms. The air filter element is installed inside a filter housing to form an air filter. However, air filters still have the following drawbacks in practical use:

[0003] In the dust removal operation of air filter cartridges, due to the long-term filtration of dust and the dust removal operation, a large amount of dust can easily accumulate on the filter material. If it is disposable filter material, it needs to be replaced directly. If it is some high-end filter material, it needs to be reused. This requires dust removal operation to be performed multiple times. However, conventional dust removal methods are very troublesome. They either need to be placed in a professional dust removal device or require corresponding dust removal tools. Moreover, the dust removal device can only perform dust removal operation at a single point, which cannot be done conveniently and quickly.

[0004] Secondly, conventional filter cartridges use a single filter material for filtration, which can only filter some dust. They cannot filter harmful substances such as organic matter, so the purification effect is generally poor, and it is also difficult to meet the requirements for sterile air. Utility Model Content

[0005] The purpose of this utility model is to provide a dust removal air filter element. By setting an outer tube, an inner frame, an upper end cover, a lower end cover, an upper ring plate, a lower ring plate, a pleated filter material, and a UV lamp, it solves the problems of the cumbersome dust removal process of air filter elements and the single function of dust removal filter elements, which do not have the functions of filtering organic matter and removing dust.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a dust removal air filter element, including an upper end cover, a lower end cover, a protective component, an outer tube, and an inner skeleton. The inner skeleton is fixedly arranged between the upper end cover and the lower end cover. An upper ring plate is movably arranged below the upper end cover outside the inner skeleton. A lower ring plate is movably arranged above the lower end cover outside the inner skeleton. A pleated filter material is fixed between the upper ring plate and the lower ring plate outside the inner skeleton. A protective component is arranged on the outside of the pleated filter material.

[0008] The inner frame includes an upper ring pipe and a lower ring pipe, and vertical pipes arranged in a ring array are fixed through the upper ring pipe and the lower ring pipe. The vertical pipes are provided with nozzles that are evenly distributed on the outer side away from the center of the upper ring pipe.

[0009] The outer wall of the upper end cover is threaded with an outer tube, and the side of the outer tube facing the pleated filter material is provided with downwardly inclined and equally spaced nozzles.

[0010] An outlet pipe is fixedly connected to the upper end cover, and a mounting base is fixed to the outer periphery of the outlet pipe, with a UV lamp fixed on the mounting base.

[0011] Furthermore, the mounting base and the outlet pipe are provided with a through groove, and the UV lamp is irradiated towards the through groove. The outer periphery of the outlet pipe above the mounting base is provided with an external thread.

[0012] Furthermore, an air intake channel is provided inside the upper end cover, and the air intake channel penetrates the side wall and bottom surface of the upper end cover. The higher end of the outer tube is threadedly connected to the outer end of the air intake channel. An interface tube is fixedly connected through the upper ring tube, and the interface tube is inserted into the end of the air intake channel away from the outer tube.

[0013] Furthermore, the protective component includes an upper sealing ring and a lower sealing ring, with a stainless steel mesh tube fixed between the upper and lower sealing rings. The upper sealing ring is fitted over the upper end cover and the upper ring plate, and the lower sealing ring is fitted over the lower end cover and the lower ring plate. A lever arranged in a ring array is fixed on the outer periphery of the upper ring plate, and a through hole arranged in a ring array is opened through the upper sealing ring, with the lever passing through the through hole.

[0014] Furthermore, the outer surface of the pleated filter material is coated with a TiO2 coating.

[0015] Furthermore, annular grooves are provided between the upper ring plate and the upper end cover, and between the lower end cover and the lower ring plate, and ball bearings arranged in a ring array are provided in the annular grooves.

[0016] This utility model has the following beneficial effects:

[0017] This invention solves the problem of cumbersome air filter cleaning by setting up an outer tube, an inner frame, an upper end cover, a lower end cover, an upper ring plate, and a lower ring plate. When the air filter needs cleaning, the protective components are removed, and then the outer tube is connected to the upper end cover. The bottom end of the outer tube is connected to an air source to input compressed air for cleaning. Then, the compressed air is sprayed from the nozzle in the outer tube and the nozzle on the vertical tube in the inner frame, respectively spraying onto the outer and inner walls of the pleated filter material, achieving simultaneous cleaning on both sides. The air sprayed from the nozzle blows the dust out of the pleated filter material, and then the dust is blown down by the inclined nozzle on the outer tube. At the same time, the upper and lower ring plates, along with the pleated filter material, can rotate under the action of ball bearings. At this time, the comprehensive cleaning operation can be achieved by the cooperation of the outer tube and the inner frame.

[0018] This invention solves the problem of dust collector filters lacking single-function capabilities, such as organic matter filtration and dust removal, by incorporating a pleated filter material and a UV lamp. During air filtration, air enters from the outside of the pleated filter material, passes through it, and then enters the inner frame. Because the outer surface of the pleated filter material is coated with a TiO2 coating, it has strong oxidation-reduction capabilities and stable chemical properties. It can completely decompose harmful organic matter, pollutants, odors, bacteria, and microorganisms such as formaldehyde, toluene, xylene, ammonia, radon, and TVOC into harmless CO2 and H2O. Combined with the decomposition and adsorption of organic dust (such as oil mist and VOCs) under UV light, it achieves more filtration functions. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] Please see Figure 1-9 As shown, this utility model is a dust removal air filter element, including an upper end cover 1, a lower end cover 2, a protective component 3, an outer tube 4 and an inner frame 8. The inner frame 8 is fixedly arranged between the upper end cover 1 and the lower end cover 2. An upper ring plate 5 is movably arranged below the upper end cover 1 outside the inner frame 8. A lower ring plate 6 is movably arranged above the lower end cover 2 outside the inner frame 8. A pleated filter material 7 is fixed between the upper ring plate 5 and the lower ring plate 6 outside the inner frame 8. The protective component 3 is arranged on the outside of the pleated filter material 7.

[0033] The upper end cover 1 and the lower end cover 2 are fixed together to form a whole, which can be done by welding. The inner frame 8 is used as a support and also as a dust removal auxiliary. A pleated filter material 7 is set between the upper ring plate 5 and the lower ring plate 6 so that it can rotate, making it easy to rotate during dust removal and making dust removal more comprehensive. Finally, the protective component 3 is on the outermost layer and is used for enhanced protection.

[0034] The inner frame 8 includes an upper ring pipe 801 and a lower ring pipe 803, and a vertical pipe 802 arranged in a ring array is fixed between the upper ring pipe 801 and the lower ring pipe 803, and nozzles 8021 are arranged at equal intervals on the outer side of the vertical pipe 802 away from the center of the upper ring pipe 801.

[0035] A vertical pipe 802 is installed between the upper ring pipe 801 and the lower ring pipe 803, and the three are internally connected to allow the cleaning gas to circulate. Compressed air is sprayed out from the nozzle 8021 on the vertical pipe 802 to remove the dust inside the pleated filter material 7.

[0036] The outer wall of the upper end cover 1 is threaded with an outer tube 4, and the side of the outer tube 4 facing the pleated filter material 7 is provided with downwardly inclined and equally distributed nozzles 401.

[0037] An inclined nozzle 401 is installed on the outer tube 4. The gas ejected from the nozzle 8021 blows out the dust in the pleated filter material 7, and then the inclined nozzle 401 on the outer tube 4 blows the dust down, making it easy to clean the dust quickly.

[0038] An outlet pipe 101 is fixedly installed through the upper cover 1. A mounting base 1012 is fixed to the outer periphery of the outlet pipe 101, and a UV lamp 1013 is fixed on the mounting base 1012. The air that enters the inside of the pleated filter material 7 is then discharged through the outlet pipe 101. When passing through the outlet pipe 101, it is irradiated by the UV lamp 1013. Under the UV light, the adsorbed organic dust (such as oil mist and VOC) is decomposed and further sterilized to obtain clean air.

[0039] A through groove 1014 is provided in the mounting base 1012 and the outlet pipe 101, and the irradiation direction of the UV lamp 1013 is towards the through groove 1014. An external thread 1011 is provided on the outer periphery of the outlet pipe 101 above the mounting base 1012. The through groove 1014 facilitates the UV lamp 1013 to irradiate the air passing through the outlet pipe 101.

[0040] An air intake channel 102 is provided inside the upper end cover 1, and the air intake channel 102 passes through the side wall and bottom surface of the upper end cover 1. The higher end of the outer tube 4 is threadedly connected to the outer end of the air intake channel 102. An interface tube 8011 is fixedly connected through the upper ring tube 801, and the interface tube 8011 is inserted into the end of the air intake channel 102 away from the outer tube 4.

[0041] The outer pipe 4 is connected to the air inlet channel 102 of the upper end cover 1. The bottom end of the outer pipe 4 is connected to the air source, and compressed air for dust removal is input. After being input into the outer pipe 4, it is sprayed out through the nozzle 401, and also enters the interface pipe 8011 and the interior of the inner frame 8 through the air inlet channel 102. It enters the vertical pipe 802 from the upper ring pipe 801 in the inner frame 8, and finally sprays out from the nozzle 8021.

[0042] The protective component 3 includes an upper sealing ring 301 and a lower sealing ring 303. A stainless steel mesh cylinder 302 is fixed between the upper sealing ring 301 and the lower sealing ring 303. The upper sealing ring 301 is sleeved on the upper end cover 1 and the upper ring plate 5. The lower sealing ring 303 is sleeved on the lower end cover 2 and the lower ring plate 6. A lever 501 arranged in a ring array is fixed on the outer periphery of the upper ring plate 5. A through hole 3011 arranged in a ring array is opened through the upper sealing ring 301, and the lever 501 passes through the through hole 3011.

[0043] During filtration, the upper sealing ring 301 is fitted over the upper end cover 1 and the upper ring plate 5, and the lower sealing ring 303 is fitted over the lower end cover 2 and the lower ring plate 6. At this time, the lever 501 passes through the through hole 3011 in the upper sealing ring 301, so that the upper ring plate 5 and the lower ring plate 6 cannot rotate. At the same time, the stainless steel mesh cylinder 302 strengthens the structural protection. The protective component 3 can be removed during dust removal.

[0044] The outer surface of the pleated filter material 7 is coated with a TiO2 coating 701. Because the TiO2 coating 701 on the outer surface of the pleated filter material 7 has a strong oxidation-reduction ability and stable chemical properties, when air passes through, it can completely decompose harmful organic substances such as formaldehyde, toluene, xylene, ammonia, radon, TVOC, pollutants, odors, bacteria, and microorganisms into harmless CO2 and H2O. The TiO2 coating 701 operates under the action of visible light or ultraviolet light. Therefore, in the case of insufficient visible light, it is necessary to place a light source outside the pleated filter material 7 or outside the stainless steel mesh cylinder 302.

[0045] Annular grooves 9 are provided between the upper ring plate 5 and the upper end cover 1, and between the lower end cover 2 and the lower ring plate 6. The annular grooves 9 are provided with ball bearings 901 arranged in a ring array. Under the action of the ball bearings 901, the upper ring plate 5 and the lower ring plate 6, together with the pleated filter material 7, rotate to perform a comprehensive dust removal operation.

[0046] The specific working principle of this utility model is as follows: First, before filtration, the upper sealing ring 301 is fitted over the upper end cap 1 and the upper ring plate 5, and the lower sealing ring 303 is fitted over the lower end cap 2 and the lower ring plate 6. At this time, the lever 501 passes through the through hole 3011 in the upper sealing ring 301, preventing the upper ring plate 5 and the lower ring plate 6 from rotating. At the same time, the stainless steel mesh cylinder 302 strengthens the structural protection. During filtration, air enters from outside the stainless steel mesh cylinder 302, then from outside the pleated filter material 7, and enters the inner frame 8 after passing through the pleated filter material 7. Because the outer surface of the pleated filter material 7 is coated with a TiO2 coating 701, it has a strong oxidation-reduction ability and can completely decompose harmful organic substances, pollutants, odors, bacteria, microorganisms, etc., such as formaldehyde, toluene, xylene, ammonia, radon, and TVOC, into harmless CO2. The air entering the inside of the corrugated filter material 7, along with H2O, is then discharged through the outlet pipe 101. As it passes through the outlet pipe 101, it is irradiated by the UV lamp 1013. Under the UV light, the adsorbed organic dust (such as oil mist and VOCs) is decomposed and further sterilized to obtain clean air.

[0047] During dust removal, the outer pipe 4 is connected to the air inlet channel 102 of the upper end cover 1 (when not removing dust, the air inlet channel 102 is blocked with a plug, etc., and the outer pipe 4 is not installed). The bottom end of the outer pipe 4 is connected to the air source, and compressed air for dust removal is input. After being input into the outer pipe 4, it is sprayed out through the nozzle 401, and also enters the interface pipe 8011 and the interior of the inner frame 8 through the air inlet channel 102. It enters the vertical pipe 802 from the upper ring pipe 801 in the inner frame 8, and finally sprays out from the nozzle 8021. The gas sprayed from the nozzle 8021 blows out the dust in the pleated filter material 7, and then the dust is blown down by the inclined nozzle 401 on the outer pipe 4. At the same time, the upper ring plate 5 and the lower ring plate 6, together with the pleated filter material 7, can rotate under the action of the ball bearing 901. At this time, the outer pipe 4 and the inner frame 8 can be used to achieve a comprehensive dust removal operation.

[0048] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
