Description

A waste gas purification device for the production of industrial equipment parts Technical Field

[0001] This invention relates to the technical field of waste gas purification equipment for the production of industrial equipment parts, specifically to a waste gas purification equipment for the production of industrial equipment parts. Background Technology

[0002] Industrial machinery parts, also known as mechanical components, are the basic components that make up machinery. They are inseparable individual parts that make up machinery and machines. When producing industrial equipment parts, welding and other operations are required. However, a large amount of waste gas is generated during the welding process, so the waste gas needs to be purified, otherwise it will endanger the health of workers.

[0003] Existing waste gas purification equipment for the production of industrial equipment parts mostly separates particulate impurities from the waste gas through spraying during the production process. However, when the waste gas contains a large number of particulate impurities, some of the impurities may adhere to the spray head, causing the spray head to become clogged and failing to effectively treat the impurities in the waste gas. In view of this, we propose a waste gas purification equipment for the production of industrial equipment parts. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a waste gas purification device for the production of industrial equipment parts, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a waste gas purification device for the production of industrial equipment parts, comprising a purification tank, an inlet pipe fixed to the right side of the purification tank, an outlet pipe fixed to the top of the purification tank, and a spray device provided on the outer wall of the purification tank. The spray device includes a water tank, a water pump, a water outlet pipe, and a spray pipe. The water tank is fixed to the outer wall of the purification tank, and the water pump is fixed to the top of the water tank. The bottom input end of the water pump is connected to the inside of the water tank. The water outlet pipe is fixed to the output end of the water pump, and the spray pipe is fixed to the outer wall of the water outlet pipe. By starting the water pump, water in the water tank can be drawn out, passed through the water outlet pipe, and sprayed out from the spray pipe to purify the waste gas. The purification tank is equipped with a drain pipe at its bottom and an activated carbon plate on its inner wall. A separation device for separating large particulate impurities is also provided on the purification tank, along with a diffusion device to improve dust removal efficiency. The separation device includes a motor, a rotating shaft, a separation plate, a fixed sleeve, a rotating rod, a friction wheel, a support block, a rotating block, a triangular block, and a return spring. The motor is fixed to the bottom of the purification tank, and the rotating shaft is fixed to the top output end of the motor. The rotating shaft passes through the bottom of the purification tank and is rotatably connected at the penetration point. The separation plate is slidably mounted on the outer wall of the rotating shaft. When the motor is started, it drives the rotating shaft to rotate, causing the rotating shaft to rotate the separation plate.

[0006] According to the above technical solution, the fixed sleeve is fixed to the inner wall of the purification tank, the support block is fixed to the outer wall of the rotating shaft, the rotating rod is rotatably installed at the bottom of the support block, the rotating rod passes through the separation plate and fits at the penetration point. When the rotating shaft rotates, it can drive the support block and the rotating rod to rotate, so that the friction wheel fits against the inner wall of the fixed sleeve and rotates, so that the friction wheel is subjected to friction force, which can drive the rotating rod to rotate.

[0007] According to the above technical solution, the friction wheel is fixed to the outer wall of the rotating rod, and the outer wall of the friction wheel is in contact with the inner wall of the fixed sleeve. The top of the return spring is fixed to the inner side of the rotating shaft, the bottom of the return spring is fixed to the outer wall of the separation plate, the triangular block is fixed to the top of the separation plate, and the rotating block is fixed to the outer wall of the rotating rod. When the rotating rod rotates, it can drive the rotating block to rotate, thereby causing the rotating block to press against the inclined surface of the triangular block, which will cause the triangular block to be subjected to compressive force and move downward.

[0008] According to the above technical solution, the diffusion device includes a connecting sleeve, a striking plate, a bending block, a pressing rod, a rotating shaft, a torsion spring, a diffusion plate, and a rotating block; the connecting sleeve is fixed to the outer wall of the rotating shaft, the striking plate is fixed to the outer wall of the connecting sleeve, the bending block is fixed to the side wall of the separation plate, the pressing rod is fixed to the outer wall of the bending block, and the pressing rod passes through the top of the striking plate and is slidably connected at the penetration point.

[0009] According to the above technical solution, the rotating shaft passes through the striking plate and is rotatably connected at the point of penetration. The rotating block is fixed to the outer wall of the rotating shaft, and the diffuser plate is fixed to the outer wall of the rotating shaft.

[0010] According to the above technical solution, one side of the torsion spring is fixed to the inner wall of the striking plate, and the other side of the torsion spring is fixed to the outer wall of the rotating block. When the rotating shaft rotates, it can drive the striking plate to rotate and strike the water droplets. When the separating plate moves downward, it can drive the bending block to move downward, so that the squeezing rod can squeeze the rotating block, causing the rotating shaft to rotate and compressing the torsion spring.

[0011] According to the above technical solution, the method further includes an intermittent device, which is installed inside the purification tank. The intermittent device includes an L-shaped block, an arc-shaped baffle, a connecting column, a compression spring, and a scraper ring. The L-shaped block is fixed to the outer wall of the connecting sleeve, and the arc-shaped baffle is fixed to the bottom of the L-shaped block.

[0012] According to the above technical solution, the connecting column is slidably installed on the inner side of the bottom of the arc-shaped baffle, the top of the compression spring is fixed to the inner wall of the arc-shaped baffle, the bottom of the compression spring is fixed to the top of the connecting column, and the scraper ring is fixed to the bottom of the connecting column. When the rotating shaft rotates, it can drive the connecting sleeve to rotate, thereby causing the L-shaped block to drive the arc-shaped baffle to rotate.

[0013] This invention provides a waste gas purification device for the production of industrial equipment parts. It has the following beneficial effects: 1. By setting up a separation device, when the waste gas enters the purification tank from the inlet pipe, starting the motor causes the rotating shaft to rotate the separation plate. This allows the separation plate to strike the incoming waste gas, thereby knocking off a large number of impurities and preventing the waste gas from carrying a large amount of solid impurities upwards. This solves the problem of waste gas containing a large amount of solid particulate impurities being discharged upwards, causing blockage of the spray pipe. Furthermore, while the separation plate is rotating, the cooperation of the rotating rod, friction wheel, fixed sleeve, rotating block, triangular block, and return spring allows the separation plate to also vibrate up and down, shaking off particles attached to the surface of the separation plate. This prevents a large amount of impurities and dust from adhering to the surface of the separation plate during long-term use, thus preventing the separation efficiency of solid impurities in the waste gas subsequently entering the purification tank from decreasing.

[0014] 2. This invention, by incorporating a diffusion device, allows the rotating shaft to rotate simultaneously with the impact plate, causing water droplets sprayed from the spray pipe to fall onto the impact plate. The impact plate then strikes the water droplets, breaking down larger droplets and increasing the contact area between the water droplets and solid impurities in the exhaust gas, thus improving the exhaust gas treatment effect. Furthermore, as the separation plate moves up and down, the combination of the bending block, extrusion rod, rotating shaft, rotating block, diffusion plate, and torsion spring causes the diffusion plate to swing while the impact plate rotates, further agitating the water droplets and diffusing them towards the edge of the purification tank. This solves the problem of particulate matter escaping due to ash leakage from the side walls of the purification tank.

[0015] 3. This invention, by setting an intermittent device, allows the L-shaped block to rotate when the connecting sleeve rotates, which in turn rotates the arc-shaped baffle. When the arc-shaped baffle rotates to the point of blocking the air intake pipe, the air intake pipe stops intake. When it rotates to the point of not blocking the air intake pipe, normal air intake can proceed. This achieves the effect of intermittently adding waste gas to the purification tank, solving the problem of continuous waste gas discharge into the purification tank, which leads to overload of the tank and prevents effective purification of impurities and waste gas. Furthermore, when the arc-shaped baffle rotates, it also drives the connecting column and scraper ring to rotate, allowing the scraper ring to remove impurities that have fallen from the purification tank and discharge them through the drain pipe, facilitating worker operations.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please refer to Figures 1-8. One embodiment of the present invention is: a waste gas purification device for the production of industrial equipment parts, including a purification tank 1, an air inlet pipe 2 fixed to the right side of the purification tank 1, an air outlet pipe 3 fixed to the top of the purification tank 1, and a spray device 4 provided on the outer wall of the purification tank 1. The spray device 4 includes a water tank, a water pump, a water outlet pipe, and a spray pipe. The water tank is fixed to the outer wall of the purification tank 1, and the water pump is fixed to the top of the water tank. The bottom input end of the water pump is connected to the inside of the water tank, the water outlet pipe is fixed to the output end of the water pump, the spray pipe is fixed to the outer wall of the water outlet pipe, a drain pipe 6 is fixed to the bottom of the purification tank 1, an activated carbon plate 5 is fixed to the inner wall of the purification tank 1, and a separation device for separating large particulate impurities is provided on the purification tank 1. The separation device includes a motor 71, a rotating shaft 72, a separation plate 73, a fixing sleeve 74, a rotating rod 75, a friction wheel 76, and a support block 77. The system includes a rotating block 78, a triangular block 79, and a return spring 710. A motor 71 is fixed to the bottom of the purification tank 1. A rotating shaft 72 is fixed to the top output end of the motor 71. The rotating shaft 72 passes through the bottom of the purification tank 1 and is rotatably connected at the point of penetration. A separation plate 73 is slidably mounted on the outer wall of the rotating shaft 72. A fixing sleeve 74 is fixed to the inner wall of the purification tank 1. A support block 77 is fixed to the outer wall of the rotating shaft 72. A rotating rod 75 is rotatably mounted on the bottom of the support block 77. The rotating rod 75 passes through the separation plate 73 and is fitted at the point of penetration. A friction wheel 76 is fixed to the outer wall of the rotating rod 75. The outer wall of the friction wheel 76 is fitted to the inner wall of the fixing sleeve 74. The top of the return spring 710 is fixed to the inner side of the rotating shaft 72, and the bottom of the return spring 710 is fixed to the outer wall of the separation plate 73. A triangular block 79 is fixed to the top of the separation plate 73, and a rotating block 78 is fixed to the outer wall of the rotating rod 75.

[0020] The friction wheel 76 is tightly attached to the inner wall of the fixed sleeve 74, so that when the friction wheel 76 rotates against the inner wall of the fixed sleeve 74, it can rotate due to friction.

[0021] When treating exhaust gas, as the exhaust gas enters the purification tank 1 through the inlet pipe 2, the starting motor 71 rotates the shaft 72, causing the separation plate 73 to rotate. This allows the separation plate 73 to strike the entering exhaust gas, knocking off a large number of impurities and preventing the exhaust gas from carrying a large amount of solid impurities upwards. This solves the problem of exhaust gas containing a large number of solid particles being discharged upwards, causing blockage of the spray pipe. Furthermore, while the separation plate 73 is rotating, the cooperation of the rotating rod 75, friction wheel 76, fixed sleeve 74, rotating block 78, triangular block 79, and return spring 710 allows the separation plate 73 to also vibrate up and down, shaking off particles attached to the surface of the separation plate 73. This prevents the separation plate 73 from accumulating a large amount of impurities and dust over long-term use, thus reducing the efficiency of separating solid impurities from the exhaust gas entering the purification tank 1.

[0022] In this embodiment, when waste gas needs to be treated, an external fan is connected to the inlet pipe 2 to draw in the waste gas generated during the production of industrial equipment parts. A water pump is started to draw liquid from the water tank, which is then sprayed out through the outlet pipe from the spray pipe. This spraying process treats the waste gas entering the purification tank 1, causing solid particles in the waste gas to fall off. The waste gas is then exhausted upwards, passing through the activated carbon plate 5 to filter harmful gases before being discharged from the outlet pipe 3. Furthermore, when the waste gas enters the purification tank 1, the motor 71 is started, causing the rotating shaft 72 to rotate clockwise. This rotation drives the separation plate 73 to rotate clockwise, allowing the separation plate 73 to impact the waste gas entering the inlet pipe 2, thus removing solid particles from the waste gas. When impurities are knocked off, and the rotating shaft 72 rotates clockwise, the support block 77 drives the rotating rod 75 to rotate, causing the friction wheel 76 to rotate against the inner side of the fixed sleeve 74. Due to friction, the friction wheel 76 rotates counterclockwise. When the friction wheel 76 rotates counterclockwise, it drives the rotating rod 75 to rotate counterclockwise. The rotating rod 75 drives the rotating block 78 to rotate. When the rotating block 78 rotates to contact the inclined surface of the triangular block 79, the triangular block 79 is squeezed and moves downward, causing the triangular block 79 to drive the separating plate 73 to move downward. When the separating plate 73 moves downward, the return spring 710 is stretched. When the rotating block 78 rotates to no longer contact the triangular block 79, the return spring 710 is stretched, allowing the return spring 710 to drive the separating plate 73 to move upward for reset.

[0023] Please refer to Figures 1-8. In another embodiment of the present invention, based on the above embodiments, the separation device is provided with a diffusion device to improve dust removal efficiency. The diffusion device includes a connecting sleeve 81, an impact plate 82, a bending block 83, a pressing rod 86, a rotating shaft 84, a torsion spring 88, a diffusion plate 85, and a rotating block 87. The connecting sleeve 81 is fixed to the outer wall of the rotating shaft 72, the impact plate 82 is fixed to the outer wall of the connecting sleeve 81, the bending block 83 is fixed to the side wall of the separation plate 73, the pressing rod 86 is fixed to the outer wall of the bending block 83, the pressing rod 86 passes through the top of the impact plate 82 and is slidably connected at the penetration point, the rotating shaft 84 passes through the impact plate 82 and is rotatably connected at the penetration point, the rotating block 87 is fixed to the outer wall of the rotating shaft 84, the diffusion plate 85 is fixed to the outer wall of the rotating shaft 84, one side of the torsion spring 88 is fixed to the inner wall of the impact plate 82, and the other side of the torsion spring 88 is fixed to the outer wall of the rotating block 87.

[0024] Four sets of impact plates 82 are fixed to the outer wall of the connecting sleeve 81 in a circumferential array. When the rotating shaft 72 rotates, it can drive the impact plates 82 to rotate, so that the water droplets sprayed from the spray pipe fall on the impact plates 82, causing the impact plates 82 to strike the water droplets. This can disperse larger water droplets, thereby increasing the contact area between the water droplets and solid impurities in the exhaust gas and improving the exhaust gas treatment effect. When the separation plate 73 moves up and down, through the cooperation of the bending block 83, the squeezing rod 86, the rotating shaft 84, the rotating block 87, the diffuser plate 85, and the torsion spring 88, the impact plates 82 can rotate while the diffuser plate 85 swings, which can beat the water droplets and diffuse them to the edge of the purification tank 1, solving the problem of particulate matter escaping due to ash leakage from the side wall of the purification tank 1.

[0025] It also includes an intermittent device, which is installed inside the purification tank 1. The intermittent device includes an L-shaped block 91, an arc-shaped baffle 92, a connecting column 93, a compression spring 94, and a scraper ring 95. The L-shaped block 91 is fixed to the outer wall of the connecting sleeve 81, the arc-shaped baffle 92 is fixed to the bottom of the L-shaped block 91, the arc-shaped baffle 92 is attached to the inner wall of the purification tank 1, the connecting column 93 is slidably installed on the inner side of the bottom of the arc-shaped baffle 92, the top of the compression spring 94 is fixed to the inner wall of the arc-shaped baffle 92, the bottom of the compression spring 94 is fixed to the top of the connecting column 93, and the scraper ring 95 is fixed to the bottom of the connecting column 93.

[0026] When the connecting sleeve 81 rotates, it drives the L-shaped block 91 to rotate, which in turn causes the arc-shaped baffle 92 to rotate. When the arc-shaped baffle 92 rotates to block the air intake pipe 2, it stops the air intake pipe 2 from taking in air. When it rotates to not block the air intake pipe 2, it allows for normal air intake, achieving the effect of intermittently adding waste gas to the purification tank 1. This solves the problem of continuously discharging waste gas into the purification tank 1, causing overload of waste gas in the purification tank 1, which prevents the effective purification of impurities and waste gas. Furthermore, when the arc-shaped baffle 92 rotates, it drives the connecting column 93 and the scraper ring 95 to rotate, allowing the scraper ring 95 to remove the impurities that have fallen from the purification tank 1 and discharge them through the drain pipe 6, facilitating the operation of the staff.

[0027] In this embodiment, during operation: when the rotating shaft 72 rotates, it drives the connecting sleeve 81 to rotate, which in turn drives the striking plate 82 to rotate. The striking plate 82 strikes the water droplets sprayed from the spray pipe, breaking large water droplets into smaller ones, increasing the contact area with particulate matter in the exhaust gas. When the separating plate 73 moves downward, it drives the bending block 83 to move downward. This downward movement of the bending block 83 drives the squeezing rod 86 downward, squeezing the rotating block 87 and causing it to rotate downward. The rotating block 87 then drives the rotating shaft 84 to rotate. As the rotating block 87 rotates, it compresses and deforms the torsion spring 88. When the rotating shaft 84 rotates, it drives the diffuser plate 85 to swing, striking and diffusing the water droplets. When the separating plate 73 returns to its original position, it drives the bending block 83 to return to its original position, causing the bending block 83 to drive the squeezing rod 86. Without pressing the rotating block 87, the torsion spring 88 is in a compressed and deformed state, which allows the torsion spring 88 to drive the rotating block 87 to reset, and the rotating block 87 to drive the rotating shaft 84 and the diffuser plate 85 to rotate and reset. When the connecting sleeve 81 rotates, it drives the L-shaped block 91 to rotate, which in turn drives the arc-shaped baffle 92 to rotate. When the arc-shaped baffle 92 rotates to the air inlet pipe 2, it can block the air inlet pipe 2, preventing the air inlet pipe 2 from discharging waste gas into the purification tank 1. When the arc-shaped baffle 92 rotates to the point where it does not block the air inlet pipe 2, it can perform normal discharge, achieving the effect of intermittently discharging waste gas into the purification tank 1. When the arc-shaped baffle 92 rotates, it can drive the connecting column 93 to rotate, which allows the scraper ring 95 to rotate against the bottom of the inner wall of the purification tank 1, removing the sprayed solid particles and discharging the particles from the drain pipe 6.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
