Description

Technical Field

[0001] This utility model relates to the field of automobile dismantling technology, and in particular to dust removal equipment for automobile dismantling. Background Technology

[0002] With the development of science and technology and society, automobiles have become one of the important means of transportation for people's daily travel. However, automobiles have a certain service life. With the long-term use of automobiles, wear and tear will increase. And automobiles that do not meet safety standards are generally recycled. During the recycling process, the scrapped automobiles are transferred to a dust removal room for dismantling. The dust removal and noise reduction equipment in the dust removal room is used to treat the dust and noise generated during the dismantling.

[0003] According to the search, the Chinese patent "A dust removal and noise reduction device for dismantling scrapped cars" authorized announcement number "CN218368063U" uses a combination of a dust suction fan, a flange and a connecting pipe to adsorb a large amount of dust generated during car dismantling and transport it to a designated location for treatment, thereby improving the dust reduction effect during dismantling.

[0004] In the aforementioned application, because the suction range of the vacuum fan is relatively fixed, the dust spreads over a large area during the disassembly of the car, making it difficult to completely absorb the scattered dust. This can easily lead to the spread of dust and thus affect the surrounding sanitary environment. Utility Model Content

[0005] Therefore, it is necessary to provide dust removal equipment for automobile dismantling to address the problem that dust spreads over a large area during automobile dismantling and is difficult to completely absorb.

[0006] The device includes: a dust removal chamber, the inner wall of which is fixedly connected to a sound-absorbing cotton board; two soundproof doors are hinged to the front end of the dust removal chamber; a dust removal frame is fixedly connected to the surface of the sound-absorbing cotton board; an exhaust fan is installed on one side of the dust removal frame; and an exhaust corrugated cover is fixedly connected to the top of the dust removal frame; and a control mechanism, which includes a noise-reducing microphone, a dust concentration sensor, and a fixing frame located on the top of the dust removal frame; a lead screw is rotatably connected to the inner wall of the fixing frame; a servo motor is fixedly connected to one end of the lead screw; the inner wall of the exhaust corrugated cover is threadedly connected to the surface of the lead screw; and the inner wall of the exhaust corrugated cover is slidably connected to the surface of the fixing frame.

[0007] In one embodiment, a sealing block is slidably connected to the inner wall of the dust removal frame, and a first filter screen, a second filter screen, a third filter screen, and an electrostatic adsorption breathable plate are fixedly connected to the surface of the sealing block.

[0008] In one embodiment, a compression frame is slidably connected to the inner wall of the dust collection frame, and an electric push rod is fixedly connected to the rear end of the compression frame. The compression frame and the electric push rod work together to compress the dust inside the dust collection frame into blocks, facilitating subsequent dust processing and preventing dust from spreading during dust collection.

[0009] In one embodiment, a sealing block is slidably connected to the inner wall of the dust collector frame. Both the sealing block and the inner wall of the sealing block are threaded with several screws, the surfaces of which are threaded onto the inner wall of the dust collector frame. The screws facilitate the removal and fixing of the sealing block and the sealing block on the dust collector frame, thereby facilitating the cleaning of the first filter, the second filter, the third filter, the electrostatic adsorption breathable plate, and the interior of the dust collector frame.

[0010] In one embodiment, rubber corrugated sleeves are fixedly connected to both sides of the exhaust bellows, and the other end of the rubber corrugated sleeves is fixedly connected to one side of the fixing frame. The surface of the lead screw is located inside the rubber corrugated sleeves. The rubber corrugated sleeves are used to protect the surface of the lead screw, preventing dust from adhering to the surface of the lead screw, thereby reducing wear between the lead screw and the exhaust bellows.

[0011] In one embodiment, a fourth filter screen is fixedly connected to the inner wall of the exhaust fan. This fourth filter screen prevents dust from entering the exhaust fan, ensuring a relatively clean interior.

[0012] In one embodiment, a plurality of rubber shock absorbers are fixedly connected to one side of the dust collection frame, with one end of each rubber shock absorber contacting one end of the exhaust fan. The rubber shock absorbers are used to reduce vibration and noise from the operating exhaust fan, thereby reducing pollution to the surrounding environment.

[0013] In one embodiment, the surface of the servo motor is fixedly connected to the inner wall of the mounting frame, and the surface of the electric push rod is fixedly connected to one side of the dust removal frame.

[0014] Beneficial effects 1. A dust concentration sensor is used to monitor the distribution of dust concentration in the dust removal chamber. Then, the dust suction position and suction power of the exhaust bellows are automatically adjusted by the servo motor, lead screw and exhaust fan to ensure that the dust in the dust removal chamber is fully adsorbed, thus ensuring the dust removal effect in the dust removal chamber of the car and ensuring the surrounding hygienic environment. 2. By combining the dust removal chamber, soundproof door and sound-absorbing cotton board, the car dismantling work area is sealed, thereby absorbing the noise generated during the dismantling of the car. The noise reduction microphone collects the noise signal through the microphone, and after being analyzed by the processor, it emits a sound wave with the opposite phase to the original noise, which cancels each other out. This reduces the noise generated by the dismantling robot in dismantling scrapped cars and allows it to pass out of the dust removal chamber, ensuring a good working environment. 3. The air inside the dust removal frame is filtered in multiple stages through the first, second, and third filters and the electrostatic adsorption breathable plate. Finally, the electrostatic adsorption method is used to further capture extremely fine dust, ensuring that the air discharged by the exhaust fan meets environmental protection standards, thereby ensuring the dust removal effect in the car dust removal chamber and thus ensuring the surrounding hygienic environment.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figures 1-5 This invention describes a dust removal device for automobile dismantling.

[0020] In one embodiment, a dust removal device for automotive dismantling includes: a dust removal chamber 500, with a sound-absorbing cotton panel 700 fixedly connected to the inner wall of the dust removal chamber 500, two soundproof doors 600 hinged to the front end of the dust removal chamber 500, a dust removal frame 100 fixedly connected to the surface of the sound-absorbing cotton panel 700, an exhaust fan 200 installed on one side of the dust removal frame 100, and an exhaust corrugated cover 300 fixedly connected to the top of the dust removal frame 100; and a control mechanism 400, which includes a noise-reducing microphone 401, a dust concentration sensor 402, and a fixing frame 403 located on the top of the dust removal frame 100, a lead screw 404 rotatably connected to the inner wall of the fixing frame 403, a servo motor 405 fixedly connected to one end of the lead screw 404, and the inner wall of the exhaust corrugated cover 300 threadedly connected to the surface of the lead screw 404 and slidably connected to the surface of the fixing frame 403.

[0021] It should be noted that the noise-canceling microphone 401 and the dust concentration sensor 402 are both installed inside the dust removal chamber 500 by bolts. The wiring harnesses on the noise-canceling microphone 401 and the dust concentration sensor 402 are installed to the power supply point inside the dust removal chamber 500. The specific installation method can be selected according to actual needs, and will not be elaborated here. The dust removal chamber 500 is a steel plate sound insulation component.

[0022] In this embodiment, when a car needs to be dismantled, the scrapped car is transferred to the dust removal chamber 500, the dismantling robot is moved into the dust removal chamber 500 and the soundproof door 600 is pushed to close the dust removal chamber 500. The switch buttons of the noise reduction microphone 401 and the dust concentration sensor 402 are operated so that the noise reduction microphone 401 collects noise signals through the microphone. After analysis by the processor, it emits sound waves with the opposite phase to the original noise, which cancel each other out, thereby reducing the noise.

[0023] The dismantling robot generates a large amount of dust during the dismantling of scrapped cars. At this time, the switch button of the exhaust fan 200 is operated to make the exhaust fan 200 run and draw out the excess air in the dust collection frame 100, so that the dust collection frame 100 forms a negative pressure, which in turn causes the exhaust corrugated hood 300 to adsorb the air and dust in the dust collection chamber 500 into the dust collection frame 100.

[0024] Dust concentration sensor 402 monitors the dust concentration in various areas of the dust removal chamber 500. When the dust concentration is high on one side of the dust removal chamber 500, dust concentration sensor 402 sends a signal and automatically turns on servo motor 405. The output shaft of servo motor 405 rotates, driving lead screw 404 to rotate. The rotating lead screw 404 drives the exhaust bellows 300 to move laterally on the surface of the fixed frame 403, so that the exhaust port of exhaust bellows 300 moves to a position with high dust concentration and automatically turns on the exhaust fan 200 with greater suction power, thereby greatly adsorbing the dust and air in that area. When the dust concentration in that area is low, the dust concentration sensor 402 automatically adjusts the suction power of exhaust fan 200, reducing the suction power of exhaust fan 200.

[0025] like Figure 4-5 As shown, a sealing block 407 is slidably connected to the inner wall of the dust collector frame 100. A first filter screen 408, a second filter screen 409, a third filter screen 410, and an electrostatic adsorption breathable plate 411 are fixedly connected to the surface of the sealing block 407. A squeezing frame 412 is slidably connected to the inner wall of the dust collector frame 100. An electric push rod 413 is fixedly connected to the rear end of the squeezing frame 412. A blocking block 416 is slidably connected to the inner wall of the dust collector frame 100. Several screws 417 are threadedly connected to the inner walls of both the sealing block 407 and the blocking block 416. The surface of the screws 417 is threadedly connected to the inner wall of the dust collector frame 100. The surface of the servo motor 405 is fixedly connected to the inner wall of the fixing frame 403. The surface of the electric push rod 413 is fixedly connected to one side of the dust collector frame 100.

[0026] In this embodiment, the exhaust corrugated hood 300 draws in air and dust and delivers them to the dust collection frame 100. The air and dust first pass through the first filter screen 408, where the filter holes are used to intercept large dust particles in the air. The filtered air then flows to the second filter screen 409. Since the filter holes on the second filter screen 409 are smaller than those on the first filter screen 408, they are used to intercept medium dust particles in the air. Fine dust particles follow the airflow to the third filter screen 410, where the filter holes are smaller than those on the second filter screen 409. These fine dust particles are then used to intercept even fine dust particles. The extremely fine dust particles pass through the first filter screen 408, the second filter screen 409, and the third filter screen 410 in sequence and are captured by the electrostatic adsorption breathable plate 411, ensuring that the air discharged from the exhaust fan 200 into the dust collection chamber 500 meets environmental protection standards.

[0027] The dust extracted from the dust collection frame 100 falls into the inner bottom wall of the dust collection frame 100. After the dust collection frame 100 has extracted dust for a period of time, the electric push rod 413 is manually activated. The telescopic end of the electric push rod 413 moves and pushes the extrusion frame 412 to move laterally inside the dust collection frame 100 and extrude the dust into blocks.

[0028] When cleaning the dust collector frame 100, the first filter screen 408, the second filter screen 409, the third filter screen 410, and the electrostatic adsorption breathable plate 411, use an electric wrench to move the screws 417 away from the dust collector frame 100 one by one, thereby releasing the fixing of the sealing block 407 and the blocking block 416. Pull the sealing block 407 away from the dust collector frame 100, so that the first filter screen 408, the second filter screen 409, the third filter screen 410, and the electrostatic adsorption breathable plate 411 are moved away from the dust collector frame 100 and cleaned. Pull the blocking block 416 to open the inner bottom wall of the dust collector frame 100, so that the blocky dust falls out of the dust collector frame 100 and the inside of the dust collector frame 100 is cleaned.

[0029] After cleaning, the sealing block 416 is inserted into the dust collection frame 100 and the screw 417 inside the sealing block 416 is threaded into the dust collection frame 100. The sealing block 407 is inserted into the dust collection frame 100 and the screw 417 inside the sealing block 407 is threaded into the dust collection frame 100, so that the first filter screen 408, the second filter screen 409, the third filter screen 410 and the electrostatic adsorption breathable plate 411 abut against the inner wall of the dust collection frame 100.

[0030] like Figure 5 As shown, rubber corrugated sleeves 406 are fixedly connected to both sides of the exhaust corrugated cover 300. The other end of the rubber corrugated sleeve 406 is fixedly connected to one side of the fixing frame 403. The surface of the lead screw 404 is located inside the rubber corrugated sleeve 406. A fourth filter screen 414 is fixedly connected to the inner wall of the exhaust fan 200. Several rubber shock absorbers 415 are fixedly connected to one side of the dust removal frame 100. One end of the rubber shock absorber 415 contacts one end of the exhaust fan 200.

[0031] In this embodiment, the rubber shock absorber 415 is typically composed of a rubber body, a metal frame, and bolts. The bolts on the rubber shock absorber 415 are threaded with nuts. The rubber shock absorber 415 can be of type VD. One end of the nut abuts against one end of the exhaust fan 200. The rubber shock absorber 415 is used to reduce the vibration and noise generated during the operation of the exhaust fan 200. The exhaust fan 200 has a short air duct, which further reduces airflow noise.

[0032] Working principle: The dust concentration sensor 402 monitors the dust concentration in various areas of the dust removal chamber 500. When the dust concentration on one side of the dust removal chamber 500 is high, the dust concentration sensor 402 will send a signal and automatically start the servo motor 405. Through the cooperation of the servo motor 405 and the lead screw 404, the exhaust port of the exhaust bellows 300 is moved to the position with higher dust concentration and the exhaust fan 200 is automatically turned on with greater suction power, thereby adsorbing a large amount of dust and air in that area. The exhaust bellows 300 draws air and dust and transports them into the dust removal frame 100. The first filter 408, the second filter 409 and the third filter 410 perform multi-stage interception of dust in the air. The electrostatic adsorption breathable plate 411 is used to adsorb fine dust in the air, so that the air discharged by the exhaust fan 200 into the dust removal chamber 500 meets environmental protection standards.

[0033] It should be noted that the dust collection frame 100, exhaust fan 200, exhaust corrugated cover 300, noise-reducing microphone 401, dust concentration sensor 402, servo motor 405, first filter 408, second filter 409, third filter 410, electrostatic adsorption breathable plate 411, sealing block 407, electric push rod 413, rubber shock absorber 415, sealing block 416, dust collection chamber 500, soundproof door 600, and sound-absorbing cotton board 700 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the exhaust fan 200, noise-reducing microphone 401, dust concentration sensor 402, servo motor 405, and electric push rod 413 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
