Description

Technical Field

[0001] The present invention belongs to the technical field of purification devices. Specifically, it particularly relates to an automatic cleaning purifier for vehicle engineering based on automotive exhaust gas purification. Background Art

[0002] With the rapid development of modern industry, the sharp increase in vehicles and the emission of waste, etc., the problem of air pollution is becoming more and more serious, and the environment on which humans depend for survival has been severely polluted. In response to this problem, at present, exhaust gas purification devices are installed on the exhaust pipes of automobiles. However, the existing automotive exhaust gas purification settings are relatively single, and do not have both the functions of filtering large particles and purifying harmful gases, resulting in incomplete filtering and purification. It will not only clog the purification device, but also the emissions are not clean, which will cause certain harm to environmental health.

[0003] After retrieval, Chinese Patent No. CN202320155321.3 discloses an automotive exhaust gas purification device, which relates to the technical field of exhaust gas purification. It includes an exhaust gas exhaust pipe, one end of the exhaust gas exhaust pipe is connected with an installation pipe, the interior of the installation pipe is threadedly connected with a filter pipe, a filtering mechanism is arranged inside the filter pipe, and one end of the filter pipe is connected with a connecting ring. A locking mechanism is arranged between the connecting ring and the installation pipe, and one end of the connecting ring is connected with an extension pipe. The present utility model is provided with a locking mechanism. After the filter pipe and the installation pipe are tightened, by the elastic force of the spring, one end of the insertion rod is inserted into the jack, which plays a role in fixing the connecting ring and the filter pipe, avoiding the filter pipe from loosening, so as to realize the stable connection between the filter pipe and the installation pipe. On the contrary, when the insertion rod is removed from the jack, the filter pipe can be easily screwed off, thus facilitating the replacement of the filtering mechanism and maintaining a good filtering effect on automotive exhaust gas;

[0004] However, when the above patent is in use, since the particles and dust adsorbed on the filter screen cannot be cleaned in time, the filter screen will be clogged after a long time, resulting in the inability of automotive exhaust gas to pass through the filter screen normally, thereby affecting the filtering of automotive exhaust gas by the filter screen. At the same time, when the above patent is in use, it is also not convenient to disassemble and install the filtering mechanism and the filter screen. Summary of the Invention

[0005] In view of the problems in the related art, the present invention proposes an automatic cleaning purifier for vehicle engineering based on automotive exhaust gas purification to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0007] The present invention is a vehicle engineering automatic cleaning purifier based on automobile exhaust purification, including a housing. A protruding block is arranged inside the housing. One end of a reset spring is fixedly installed at both ends of the protruding block, and the other end of the reset spring is fixedly installed inside the housing. A filter screen is arranged inside the housing. An impeller is rotatably installed on the filter screen, and a cleaning brush is fixedly installed on the impeller. A filtering mechanism is arranged inside the housing, and the filtering mechanism includes an activated carbon filter screen, an impurity adsorption layer, a dual purification filter element, and a catalyst reaction layer arranged inside the housing. An air inlet pipe and an air outlet pipe are respectively arranged at both ends of the housing, and installation mechanisms are arranged on both the air inlet pipe and the air outlet pipe.

[0008] Further, the installation mechanism includes a connecting piece arranged on the air inlet pipe. The connecting piece is fixedly installed on the air inlet pipe. The connecting piece is fixedly installed with a protruding block. An expansion rod is fixedly installed above the protruding block. A shock-absorbing spring is sleeved on the expansion rod, and an installation bolt is fixedly installed at the top of the expansion rod.

[0009] Further, for the installation mechanism arranged on the air outlet pipe, its parts and installation method are the same as those of the installation mechanism arranged on the air inlet pipe.

[0010] Further, the protruding block is slidably connected inside the housing. Sliders are fixedly installed at both ends of the protruding block. One end of the reset spring is fixedly installed on the slider, and the other end is fixedly installed inside the housing. One end of the protruding block is arc-shaped, and a handle is fixedly installed at one end of the protruding block.

[0011] Further, a limiting ring is fixedly installed inside the housing. One side of the catalyst reaction layer is closely attached to the limiting ring. A connecting shaft is rotatably installed on the filter screen. The impeller is fixedly installed on the connecting shaft. A collar is fixedly installed on the connecting shaft. A rotating rod is fixedly installed on the collar, and the cleaning brush is fixedly installed on the rotating rod.

[0012] Further, a dust collection box is fixedly installed below the housing. The dust collection box is directly opposite to the lower part of the filter screen, and the cleaning brush is closely attached to the filter screen.

[0013] Further, a filter screen is clamped at one end of the protruding block away from the arc shape.

[0014] Further, the housing can be made of stainless steel material. The air inlet pipe and the air outlet pipe are fixedly installed on end covers, and the end covers are welded to the housing.

[0015] The present invention has the following beneficial effects:

[0016] 1. After the exhaust gas enters the interior of the shell through the present invention, the exhaust gas will exert a force on the impeller. Since the shape of the impeller is reasonably designed, the airflow speed is faster at the top and slower at the bottom, thereby generating a pressure difference, causing the impeller to move toward the low-pressure area and rotate, thereby driving the cleaning brush to rotate, and then the filter can be cleaned to prevent the filter from being blocked and affecting work efficiency.

[0017] 2. The present invention pushes the filter into the shell. During the pushing process, the filter squeezes the two protruding blocks so that they completely enter the shell. When the filter moves to a suitable position, the two protruding blocks move upward under the elastic force of the return spring and press against the two sides of the filter, so that the filter can be fixed. The filter mechanism is similar. When it needs to be disassembled, it only needs to pull the handle.

[0018] 3. The present invention can fix the connecting member 14 on the car by installing the bolts 18, and then the entire device can be fixedly installed. When encountering shaking and bumps, the telescopic rod 16 and the shock-absorbing spring 17 are used to absorb shock, so that violent shaking will not occur, thereby ensuring the stability of its internal parts.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Next, the technical solutions in the embodiments of the invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the invention without creative efforts shall fall within the protection scope of the invention.

[0031] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention.

[0032] Please refer to Figures 1-7 As shown, the present invention is an automatic cleaning purifier for vehicle engineering based on automotive exhaust gas purification, including an outer shell 1. Inside the outer shell 1, there is a protruding block 2. One end of a return spring 4 is fixedly installed at both ends of the protruding block 2, and the other end of the return spring 4 is fixedly installed inside the outer shell 1. Inside the outer shell 1, there is a filter screen 5. An impeller 6 is rotatably installed on the filter screen 5. A cleaning brush 7 is fixedly installed on the impeller 6. Inside the outer shell 1, there is a filtering mechanism. The filtering mechanism includes an activated carbon filter screen 8, an impurity adsorption layer 9, a double purification filter element 10, and a catalyst reaction layer 11 arranged inside the outer shell 1. An air inlet pipe 13 and an air outlet pipe 12 are respectively arranged at both ends of the outer shell 1. Installation mechanisms are arranged on both the air inlet pipe 13 and the air outlet pipe 12.

[0033] The working principle of an automatic cleaning purifier for vehicle engineering based on automotive exhaust purification proposed by the present invention is as follows. When installing the filter screen 5, the filter screen 5 is pushed into the interior of the housing 1. During the pushing process, the filter screen 5 squeezes the two protruding blocks 2, causing them to fully enter the interior of the housing 1. When the filter screen 5 moves to a suitable position, the two protruding blocks 2 move upward under the elastic force of the return spring 4 and abut against both sides of the filter screen 5, thereby fixing the filter screen 5.

[0034] Similarly, the filtering mechanism is installed using the same method and will not be elaborated here.

[0035] Through the settings of the activated carbon filter screen 8, the impurity adsorption layer 9, the dual purification filter element 10, and the catalyst reaction layer 11, it can play a dual purification role on the gas and improve the exhaust gas purification efficiency.

[0036] When the exhaust gas enters the interior of the housing 1 through the intake pipe 13, the exhaust gas exerts a force on the impeller 6. Due to the reasonable shape design of the impeller 6, the air flow speed is faster at the top and slower at the bottom, thereby generating a pressure difference, causing the impeller 6 to move towards the low-pressure area and rotate, thus driving the cleaning brush 7 to rotate, and further cleaning the filter screen 5 to prevent the filter screen 5 from being blocked and affecting the working efficiency.

[0037] When it is necessary to disassemble the filtering mechanism and the filter screen 5, the staff only needs to pull the protruding block 2, thereby driving the protruding block 2 to move towards the outside of the housing 1, and then making the protruding block 2 retract into the interior of the housing 1, thus releasing the clamping of the filter screen 5 and the filtering mechanism, and facilitating its disassembly.

[0038] In one embodiment, for the above-mentioned installation mechanism, the installation mechanism includes a connecting piece 14 provided on the intake pipe 13. The connecting piece 14 is fixedly installed on the intake pipe 13. The connecting piece 14 is fixedly installed with a protruding block 15. Above the protruding block 15, a telescopic rod 16 is fixedly installed. The telescopic rod 16 is sleeved with a shock-absorbing spring 17. The top of the telescopic rod 16 is fixedly installed with an installation bolt 18.

[0039] In one embodiment, for the above-mentioned outlet pipe 12, the installation mechanism provided for the outlet pipe 12 has the same parts and installation method as the installation mechanism provided for the intake pipe 13.

[0040] The working principle of an automatic cleaning purifier for vehicle engineering based on automotive exhaust purification proposed by the present invention is that by using the installation bolt 18, the connecting piece 14 can be fixedly installed on the vehicle, and then the whole device can be fixedly installed. When encountering shaking and bumps, the telescopic rod 16 and the shock-absorbing spring 17 are used to dampen the shock, so that there will be no violent shaking, ensuring the stability of its internal parts.

[0041] In one embodiment, for the protruding block 2 described above, the protruding block 2 is slidably connected inside the housing 1. Sliders 19 are fixedly installed at both ends of the protruding block 2. One end of the return spring 4 is fixedly installed on the slider 19, and the other end is fixedly installed inside the housing 1. One end of the protruding block 2 is arc-shaped, and a handle 20 is fixedly installed at one end of the protruding block 2.

[0042] The working principle of an automatic cleaning purifier for vehicle engineering based on automotive exhaust purification proposed by the present invention is that by designing the handle 20, it is convenient for the staff to pull the protruding block 2. Since one end of the protruding block 2 is arc-shaped, it is convenient for the filter net 5 and the filtering mechanism to slide into the interior of the housing 1.

[0043] In one embodiment, for the housing 1 described above, a limiting ring 21 is fixedly installed inside the housing 1. One side of the catalyst reaction layer 11 is closely attached to the limiting ring 21. A connecting shaft 22 is rotatably installed on the filter net 5. An impeller 6 is fixedly installed on the connecting shaft 22. A collar 23 is fixedly installed on the connecting shaft 22. A rotating rod 24 is fixedly installed on the collar 23. A cleaning brush 7 is fixedly installed on the rotating rod 24.

[0044] In one embodiment, for the housing 1 described above, a dust collection box 25 is fixedly installed below the housing 1. The dust collection box 25 is directly opposite to the lower part of the filter net 5, and the cleaning brush 7 is closely attached to the filter net 5.

[0045] In one embodiment, for the protruding block 2 described above, a filter net 5 is clamped at the end of the protruding block 2 away from the arc shape.

[0046] In one embodiment, for the housing 1 described above, the housing 1 can be made of stainless steel. The intake pipe 13 and the exhaust pipe 12 are fixedly installed on the end cover 3, and the end cover 3 is welded to the housing 1.

[0047] The working principle of an automatic cleaning purifier for vehicle engineering based on automotive exhaust purification proposed by the present invention is that the position of the catalyst reaction layer 11 can be restricted by the limiting ring 21. The exhaust gas drives the impeller 6 to rotate, thereby driving the connecting shaft 22 to rotate, and further driving the collar 23 to rotate, thereby driving the rotating rod 24 to rotate, and further driving the cleaning brush 7 to rotate. Since the cleaning brush 7 is closely attached to the filter net 5, the filter net 5 can be cleaned, and the dust removed falls down under the action of gravity and finally falls into the interior of the dust collection box 25 for collection.
