Technical Field
[0001] This utility model relates to the field of air purifier technology, and in particular to a detachable paint spray exhaust gas filter integrated purification processor. Background Technology
[0002] According to Chinese Publication No. CN205340405U, a box-type oil mist separator filter includes: an outer frame, a paper filter element, a paper partition support frame, an inner frame, and an outer casing. The standard dimensions of the outer frame are 500*500*500mm or 500*500*300mm. Five or three different inner frames are connected to the corresponding outer frames to form a filter housing. Each unit is made of paper material and designed with a gradually decreasing channel shape, ensuring that the air containing oil mist is constantly circulating and decelerating, thus separating and intercepting the oil mist. After a period of operation, one or more units can be replaced depending on the degree of filter clogging. Even simply adjusting the position of the housing in different locations can effectively reduce the cost of the filter.
[0003] Existing paint spray exhaust filter cartridges are usually used in series, which means that when replacement is needed, operators must disassemble, remove and install them one by one. This makes the replacement process more cumbersome, especially in confined or high-altitude working environments, making cartridge replacement time-consuming and labor-intensive. Utility Model Content
[0004] The purpose of this invention is to solve the problem that in the existing technology, when replacement is required, operators must disassemble, remove and install each filter one by one, which makes the replacement process more cumbersome, especially in confined or high-altitude working environments, making filter replacement time-consuming and labor-intensive. Therefore, this invention proposes a detachable paint spray exhaust gas filter integrated purification processor.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a detachable paint spray exhaust gas filter integrated purification processor, including a purifier, an air outlet on the top surface of the purifier, an air inlet on the bottom surface of the purifier, three maintenance doors on one side of the purifier, a filter chamber at the top of the air inlet, two mounting grooves on both sides of the inner wall of the filter chamber, magnets inside the mounting grooves, a mounting frame inside the filter chamber, three sliding grooves on both sides of the mounting frame, three filter cartridge bodies in the middle of the mounting frame, plate-type activated carbon at the top of the filter chamber, a fan at the top of the plate-type activated carbon, pin holes on both sides of the mounting frame, and pin holes on both sides of the inner wall of the filter chamber, fixing pins inside the pin holes on both sides of the mounting frame, a movable groove at one end of each sliding groove on both sides of the mounting frame, a guide rod inside each movable groove, a return spring outside each guide rod, a locking tongue on one side of each return spring, and a baffle on one side of each movable groove.
[0006] Preferably, all three access doors are connected to the purifier via hinges, the plate activated carbon and the fan are both located inside the purifier, the plate activated carbon is inserted into the purifier, and the fan is bolted to the purifier.
[0007] Preferably, the two mounting slots on the inner walls of both sides of the filter chamber are parallel, and the positions of the mounting slots on the inner walls of both sides of the filter chamber correspond one-to-one. The magnets inside the mounting slots are all bonded to the purifier.
[0008] Preferably, the sliding grooves on both sides of the mounting frame are vertically arranged at equal intervals, and the positions of the sliding grooves on both sides of the mounting frame correspond one-to-one. Both ends of the filter element body are installed in the sliding grooves on both sides of the mounting frame.
[0009] Preferably, the positions of the pin holes on the inner walls of both sides of the mounting bracket correspond one-to-one, and the positions of the pin holes on the inner walls of both sides of the filter chamber correspond one-to-one with the positions of the pin holes on the surfaces of both sides of the mounting bracket. The fixing pins are installed in the pin holes of the mounting bracket and the filter chamber, and the mounting bracket is installed inside the filter chamber by the fixing pins.
[0010] Preferably, the movable grooves on both sides of the inner wall of the mounting bracket are parallel to the sliding groove, and the guide rods inside the movable groove are integrally formed with the mounting bracket.
[0011] Preferably, the reset springs inside the movable groove are all sleeved with the guide rod, the locking tongue is installed inside the movable groove through a baffle, and one end of the locking tongue extends through the movable groove, and the baffle is bolted to the mounting bracket.
[0012] Beneficial effects
[0013] In this invention, a new filter element body is pre-installed in a spare mounting bracket before replacement. During installation, the filter element body is inserted into the mounting bracket's sliding groove and pushed. As the filter element moves, it knocks open the locking tongues on both sides, pressing it into the movable groove and compressing the return spring. After the filter element is fully inserted, the locking tongues pop out under the spring's action and lock the filter element, completing the installation. When the filter element needs to be replaced, simply open the access door, pull out the fixing pin to release the mounting bracket's lock, pull out the old mounting bracket, and then push the spare mounting bracket with the new filter element installed into the filter chamber. After the mounting bracket is fully pushed in, its pin holes on both sides align with the pin holes on the inner wall of the filter chamber. Because the mounting bracket is made of metal, it is initially attracted and fixed by the magnet on the inner wall. Then, the fixing pin is inserted, and further fixation is achieved through the friction between the fixing pin and the pin hole. This solves the problem that when replacement is needed, operators must disassemble, remove, and install each filter element one by one, which makes the replacement process more cumbersome, especially in confined or high-altitude working environments, making filter element replacement time-consuming and labor-intensive.

The top of the plate-type activated carbon 11 is equipped with… The fan 12 and the mounting bracket 8 both have pin holes 13 on their sides, and the inner walls of the filter chamber 5 also have pin holes 13 on both sides. The pin holes 13 on both sides of the mounting bracket 8 each have a fixing pin 14 inside. One end of the sliding grooves 9 on both sides of the mounting bracket 8 has a movable groove 15. The movable groove 15 has a guide rod 17 inside, and a return spring 19 is provided on the outside of each guide rod 17. A locking tongue 18 is provided on one side of each return spring 19. A baffle 16 is provided on one side of each movable groove 15. All three inspection doors 3 are hinged to the purifier 1. The plate activated carbon 11 and the fan 12 are both located inside the purifier 1. The activated carbon 11 is plugged into the purifier 1, and the fan 12 is bolted to the purifier 1. The two mounting grooves 6 on the inner walls of both sides of the filter chamber 5 are parallel, and the positions of the mounting grooves 6 on the inner walls of both sides of the filter chamber 5 correspond one-to-one. The magnets 7 inside the mounting grooves 6 are all bonded to the purifier 1. The sliding grooves 9 on the inner walls of both sides of the mounting frame 8 are equally spaced and vertically arranged, and the positions of the sliding grooves 9 on the inner walls of both sides of the mounting frame 8 correspond one-to-one. Both ends of the filter element body 10 are installed in the sliding grooves 9 on the inner walls of both sides of the mounting frame 8. The positions of the pin holes 13 on the inner walls of both sides of the mounting frame 8 correspond one-to-one, and the positions of the pin holes 13 on the inner walls of both sides of the filter chamber 5 are also... The positions of the pin holes 13 on both sides of the mounting frame 8 correspond one-to-one. The fixing pins 14 are installed in the pin holes 13 of the mounting frame 8 and the filter chamber 5. The mounting frame 8 is installed inside the filter chamber 5 through the fixing pins 14. The movable grooves 15 on both sides of the inner wall of the mounting frame 8 are parallel to the sliding grooves 9. The guide rods 17 inside the movable grooves 15 are integrally formed with the mounting frame 8. The return springs 19 inside the movable grooves 15 are sleeved with the guide rods 17. The locking tongue 18 is installed inside the movable grooves 15 through the baffle 16, and one end of the locking tongue 18 extends through the movable grooves 15. The baffle 16 is bolted to the mounting frame 8.
[0029] In use, the detachable paint spray exhaust gas filter integrated purification processor allows polluted gas to enter first through the air inlet 4 at the bottom of the purifier 1. After entering the purifier 1, it enters the filter chamber 5 located at the top, which is the space for installing the filter element assembly. Two parallel mounting slots 6 are provided on the inner walls of both sides of the filter chamber 5. Magnets 7 are embedded in the mounting slots 6, using magnetic force to attract the mounting frame 8, providing initial positioning and fixation. The magnets 7 are installed into the mounting slots 6 by adhesive bonding. The horizontal layout of the mounting slots 6 ensures that the mounting frame 8 can fully engage with the magnets 7 inside the mounting slots 6 when pushed forward, preventing the magnets 7 from being moved by the mounting frame 8 and thus causing positional displacement. The mounting frame 8 is a metal structure with three equally spaced sliding grooves 9 vertically arranged on its inner walls on both sides. The sliding grooves 9 are used to insert the two ends of the filter element body 10, ensuring that the filter element is stably fixed inside the mounting frame 8. When installing the filter element, the two ends of the filter element body 10 are inserted into the sliding grooves 9 respectively, and during the pushing process, the locking tongue 18 inside the movable groove 15 of the mounting frame 8 is pressed. The locking tongue 18 is connected to the return spring 19 via the guide rod 17, which passes through the locking tongue 18. The locking tongue 18 is fixed inside the movable groove 15 by the baffle 16, preventing it from detaching from the guide rod 17 and the movable groove 15. During the compression process, the locking tongue 18 is pushed by the filter element and compresses the return spring 19, moving it into the movable groove 15. When the filter element is fully in place, the locking tongue 18 automatically pops out under the action of the return spring 19, locking the filter element and achieving self-locking fixation between the filter element and the mounting bracket 8, preventing displacement of the filter element during operation. The mounting bracket 8 has pin holes 13 on both sides, corresponding to the pin holes 13 on the inner walls of the filter chamber 5. When the mounting bracket 8 is pushed into the filter chamber 5, the metal mounting bracket 8 is attracted by the magnet 7 and aligned with the pin holes 13. At this time, inserting the fixing pin 14 achieves secondary fixation between the mounting bracket 8 and the filter chamber 5. The fixing pin 14 achieves a tight connection through friction with the pin holes 13, enhancing structural stability and preventing the mounting bracket 8 from loosening due to vibration. After the filter element is installed, airflow enters through the air inlet 4, passes through the filter element body 10 for particulate and preliminary filtration of harmful substances, and then enters the plate activated carbon 11 area at the top of the filter chamber 5 for further adsorption and purification of volatile organic compounds in the gas. The plate activated carbon 11 is fixed inside the purifier 1 by plugging in, facilitating replacement and maintenance. The fan 12 is located above the plate activated carbon 11 and is connected to the purifier 1 by bolts. When the fan 12 is started, it generates negative pressure, which discharges the treated air from the air outlet 2 on the top surface, completing the entire waste gas treatment process. The fan 12 is connected to an external control panel via wiring and is powered by an external power source. The operator controls the fan 12 through the external control panel. When the filter element needs to be replaced, the inspection door 3 on one side of the purifier 1 is opened, and the connection between the mounting bracket 8 and the filter chamber 5 is released by pulling out the fixing pin 14. The entire mounting bracket 8, along with the filter element, can then be pulled out and replaced with a spare mounting bracket 8 pre-installed with a new filter element.After the new mounting bracket 8 is pushed into the filter chamber 5, it is attracted and aligned by the magnet 7. The final fixation is completed by re-inserting the fixing pin 14. There is no need to disassemble and install each filter element individually, which improves the replacement efficiency and is especially suitable for working environments with limited space or high installation positions. Specific Implementation Example 2:
[0031] Reference Figure 1-9A detachable paint spray exhaust gas filter integrated purification processor, further based on the basic structure in Specific Embodiment 1, allows exhaust gas generated during paint spraying operations to first enter through the air inlet 4 at the bottom of the purifier 1. Under the negative pressure generated by the built-in fan 12 of the purifier 1, the airflow is rapidly drawn into the purifier 1 and enters the filter chamber 5 located above the air inlet 4. The filter chamber 5 is equipped with a metal mounting bracket 8 for accommodating the filter element body 10, with sliding grooves 9 on both sides for fixing the filter element. After entering the filter chamber 5, the exhaust gas first passes through the vertically arrayed filter element bodies 10. These filter elements perform primary filtration, mainly physically intercepting and initially adsorbing suspended particulate matter, paint droplets, and harmful particles in the exhaust gas. The filter elements are installed in the sliding grooves 9 and automatically locked by locking tongues 18 to ensure that the filter elements do not loosen or shift during operation. After passing through the filter element bodies 10, the exhaust gas flows upward to the top of the filter chamber 5, contacting the plate-type activated carbon 11 installed at the top. Plate-type activated carbon 11 is used to further adsorb residual volatile organic compounds and odor molecules, completing the deep purification of harmful chemicals in the gas. Since the activated carbon plates are installed inside the purifier 1 using a plug-in method, it is easy to replace and maintain later. The clean air treated by the activated carbon continues to flow upwards and enters the area of the fan 12 located above the activated carbon. The fan 12 is fixed to the top of the purifier 1 with bolts, and its operation generates continuous suction, exhausting the purified air to the external environment through the air outlet 2 at the top of the purifier 1, realizing a closed-loop cycle of the entire purification process. While maintaining high-efficiency purification, this device achieves a quick replacement mechanism through optimization of the filter element installation structure. After the metal pin holes 13 on both sides of the mounting bracket 8 are aligned with the pin holes 13 on the inner wall of the filter chamber 5, a stable connection is achieved by inserting fixing pins 14. The fixing pins 14 maintain the stability of the mounting bracket 8 through friction. When the mounting bracket 8 is pushed in, its metal material is attracted by the magnets 7 in the mounting slots 6 on both sides of the filter chamber 5, achieving initial positioning and effectively assisting in the alignment operation. Each filter element body 10 is pre-installed on the spare mounting bracket 8, and automatically compresses the locking tongue 18 when pushed into the slide 9, causing it to retract into the movable slot 15. After the filter element is in place, the locking tongue 18 pops out under the action of the return spring 19 and locks the filter element, achieving tool-free self-locking installation and ensuring the stability and safety of the filter element during operation. When the filter element is saturated and needs to be replaced, the operator only needs to open the inspection door 3 on one side of the purifier 1, pull out the fixing pin 14, and pull out the entire mounting bracket 8 along with the old filter element, without having to disassemble the filter elements one by one. After the new filter element is pre-installed outside the mounting bracket 8, it is directly pushed into the filter chamber 5, and quickly aligned by magnetic attraction. Then, the fixing pin 14 is inserted to complete the final fixation. The entire replacement process does not rely on complex operations or tools, saving time and manpower, and is particularly suitable for working environments with limited space or frequent replacements.
[0032] In summary:
[0033] 1. Before replacing the filter element body 10, the new filter element body 10 is pre-installed in the spare mounting bracket 8. During installation, the filter element body 10 is inserted into the slide groove 9 of the mounting bracket 8 and pushed. During the movement, the filter element will knock open the locking tongues 18 on both sides, pressing it into the movable groove 15 and compressing the return spring 19. After the filter element is fully inserted, the locking tongues 18 pop out under the action of the spring and lock the filter element, completing the installation. When it is necessary to replace the filter element, simply open the inspection door 3, pull out the fixing pin 14 to release the locking of the mounting bracket 8, pull out the old mounting bracket 8, and then push the spare mounting bracket 8 with the new filter element installed into the filter chamber 5. After the mounting bracket 8 is fully pushed in, the pin holes 13 on both sides are aligned with the pin holes 13 on the inner wall of the filter chamber 5. Since the mounting bracket 8 is made of metal, it will be initially attracted and fixed by the magnet 7 on the inner wall. Then, the fixing pin 14 is inserted, and the fixing pin 14 is further fixed by friction with the pin hole 13. This solves the problem that when it is necessary to replace the filter element, the operator must disassemble, remove and install it one by one, which makes the replacement process more cumbersome, especially in narrow or high working environments, making the replacement of the filter element time-consuming and labor-intensive.
