Description

Technical Field

[0001] The present invention relates to the technical field of gas purification, and particularly to a gas purification device for mechanical processing. Background Art

[0002] Mechanical processing refers to the process of changing the shape, size or performance of a workpiece through mechanical equipment in a factory building. There will be a large amount of waste gas during the processing of workpieces in a mechanical processing workshop. The main function of a gas purification device is to remove harmful gases, dust and oil mist generated during the workpiece processing to ensure the safety of the working environment and the normal operation of the equipment. The gas purification device can effectively improve the mechanical processing environment, protect the health of operators, extend the service life of the equipment, and meet environmental protection requirements.

[0003] The patent with the publication number CN210699366U discloses a gas purification device, including a purification box body and a filter plate component. Among them, reaction gas inlets and air outlet through holes are formed on the outer surface of the purification box body. The filter plate component includes a lower filter plate. The bottom of the lower filter plate is fixed to the bottom of the inner cavity of the purification box body, and the top of the lower filter plate is fixed to the right side surface of the inner cavity of the purification box body. The reaction gas inlets are located between the two connection parts of the lower filter plate and the purification box body. In this gas purification device, gas enters through the reaction gas inlets, passes through the lower plate holes formed inside the lower filter plate and enters the inside of the purification box body. The lower filter plate can filter larger particles in the gas, and then a spray pipe sprays and washes the gas located inside the purification box body to further reduce the solid particles in the gas, thereby avoiding a large amount of solid particles in the gas from adhering to the outside of the gas adsorption cotton layer.

[0004] However, the current gas purification device has the following problems: When the gas purification device is in use, since the gas purification device purifies the air in the mechanical processing workshop, the dust filter net in the equipment is extremely likely to be attached with a large amount of workshop dust, resulting in a large amount of dust particles and metal particles adhering to the mesh surface, causing poor air purification effect. Therefore, we propose a gas purification device for mechanical processing. Summary of the Invention

[0008] According to the above technical solution, a number of blocking rods are arranged on the inner wall of the air suction hood, a number of ventilation slots are provided on the outer wall of the heat dissipation shell, and the filter screen in the wire frame has magnetism.

[0009] According to the above technical solution, the activated carbon plate is located on the right side of the wire frame, the screw rod is located on the left side of the wire frame, and the outer wall of the scraper is in sliding contact with the left side of the wire frame.

The cross bars are located on the left side of the circular straight pipe. Two L-shaped frames are fixed to the outer wall of the cross bars. Two arc plates are respectively fixed to the opposite sides of the two L-shaped frames. Two sponge blocks are respectively fixed to the opposite sides of the two arc plates. The opposite sides of the two sponge blocks are in sliding contact with the outer wall of the screw rod. During the downward movement of the sponge blocks, the sponge blocks wipe the spiral grooves of the screw rod, so that a large amount of dust particles and metal particles will not accumulate in the spiral grooves of the screw rod.

[0011] According to the above technical solution, a square plate is fixed to the middle of the left side of the cross bar. A sliding rod is inserted through and slidably installed on the top surface of the square plate. A rubber pad is fixed to the bottom surface of the sliding rod.

[0014] The present invention provides a gas purification device for mechanical processing. It has the following beneficial effects:

[0015] (1) In the present invention, through the cooperation of the cylinder shell, the suction hood, the air extraction pump, the round cover, the mesh frame, the activated carbon plate, the heat dissipation shell, the servo motor, the screw rod, the circular straight pipe, the scraping plate and the V-shaped frame with the U-shaped rod, the mesh frame blocks the dust particles in the workshop. The magnetism of the mesh surface of the mesh frame can effectively adsorb the metal particles in the air. The activated carbon plate filters the harmful gases and oil mist in the air. The circular straight pipe drives the scraping plate to move downward. During the downward movement of the scraping plate, the scraping plate scrapes off the dust particles and metal particles on the mesh surface of the mesh frame, preventing a large amount of dust particles and metal particles from adhering to the mesh surface of the mesh frame and causing poor air purification effect.

[0016] (2) Through the setting of the anti-adhesion device in the present invention, the cross bar, the L-shaped frame and the arc plate cooperate with the sponge block. The arc plate drives the sponge block to move downward. During the downward movement of the sponge block, the sponge block wipes the spiral groove of the screw, so that a large amount of dust particles and metal particles will not accumulate in the spiral groove of the screw, preventing the screw from being easily aged and damaged due to the accumulation of a large amount of dust particles and metal particles in the spiral groove of the screw.

[0017] (3) Through the setting of the anti-adhesion device in the present invention, the square plate, the slide bar, the rubber pad and the round plate cooperate with the spring. During the downward movement of the rubber pad, it contacts the cylinder shell. Under the action of the extrusion force, the slide bar slides upward in the square plate. The slide bar drives the round plate to move upward, and the round plate drives the spring to move upward. The spring is stretched by the round plate. Under the elastic force of the spring, the arc plate will not bump into the cylinder shell when moving downward, preventing the arc plate from being easily damaged due to bumping into the cylinder shell.

[0018] (4) Through the setting of the amplitude device in the present invention, the L-shaped long plate, the U-shaped hole frame and the thin rod cooperate with the arc-shaped elastic sheet. The arc-shaped elastic sheet slides on the mesh surface of the mesh frame, causing the mesh surface of the mesh frame to vibrate, so that the dust in the mesh gaps falls off, preventing a large amount of dust from remaining in the mesh gaps of the mesh frame, resulting in poor air purification effect of the mesh frame.

[0019] (5) Through the setting of the amplitude device in the present invention, the ring block and the inclined plate cooperate with the cushion plate. During the downward movement of the cushion plate, the vibration on the thin rod is transmitted to the cushion plate, and the cushion plate transmits the vibration to the scraper, causing the scraper to vibrate and scrape off the dust particles and metal particles on the mesh surface of the mesh frame, preventing it from being difficult to scrape off the dust particles and metal particles on the mesh surface cleanly, resulting in poor air intake effect of the mesh surface.

An amplitude device 17 is arranged on the front and back sides of the anti-adhesion device 16, and the amplitude device 17 is used to vibrate the mesh surface of the wire frame 5. The cylindrical shell 1 is fixedly installed at the bottom end inside a rectangular shell 14, the round cover 4 is located above the rectangular shell 14, the air suction hood 2 is penetrated and fixed on the inner wall on the right side of the rectangular shell 14, the air extraction pump 3 is fixedly installed at the bottom end inside the rectangular shell 14, and the exhaust pipe of the air extraction pump 3 is penetrated and fixed on the inner wall on the left side of the rectangular shell 14. A control console is arranged on the left side of the front surface of the rectangular shell 14, a maintenance opening is opened on the right side of the front surface of the rectangular shell 14, a bottom frame 15 is fixed on the bottom surface of the rectangular shell 14.

[0030] Since the gas purification device is in the process of purifying the air in the machining workshop, the dust filter in the equipment is very likely to be attached with a large amount of workshop dust. When in use, the base frame 15 supports the rectangular shell 14, the rectangular shell 14 supports the cylinder shell 1, and the cylinder shell 1 supports the round cover 4. The operator uses the control console on the rectangular shell 14 to start the vacuum pump 3, and the vacuum pump 3 extracts the air in the cylinder shell 1. The cylinder shell 1 sucks the air in the machining workshop through the suction hood 2. The air enters the cylinder shell 1, and the mesh frame 5 blocks the dust particles in the workshop. At the same time, the magnetism of the mesh surface of the mesh frame 5 can effectively absorb the metal particles in the air, and the activated carbon plate 6 filters the harmful gases and oil mist in the air. When the mesh surface of the mesh frame 5 is covered with more dust particles, the round cover 4 supports the heat dissipation shell 7, and the operator uses the console to start the servo Motor 8, the rotating shaft of servo motor 8 starts to rotate forward, the rotating shaft of servo motor 8 drives screw 9 to rotate forward, screw 9 rotates in cylinder shell 1, V-shaped frame 12 is restricted by U-shaped rod 13, round straight tube 10 slides downward in the spiral groove of screw 9, round straight tube 10 drives V-shaped frame 12 to move downward, V-shaped frame 12 slides downward on U-shaped rod 13, round straight tube 10 drives scraper 11 to move downward, in the process of scraper 11 moving downward, scraper 11 scrapes off dust particles and metal particles on the mesh surface of mesh frame 5 to prevent a large amount of dust particles and metal particles from being attached to the mesh surface of mesh frame 5 when the equipment is in use, thereby avoiding the problem of poor air purification effect caused by a large amount of dust particles and metal particles attached to the mesh surface of mesh frame 5 when the gas purification device is purifying the air.

[0031] See also Figures 1-7 On the basis of the above embodiment, in another embodiment of the present invention, a cross bar 161 is embedded in the front and rear inner walls of the V-shaped frame 12, the cross bar 161 is located on the left side of the round straight tube 10, and two L-shaped frames 162 are fixed to the outer wall of the cross bar 161, and two arc plates 163 are fixed opposite the two L-shaped frames 162, and two sponge blocks 164 are fixed opposite the two arc plates 163, and the two sponge blocks 164 are in sliding contact with the outer wall of the screw 9 opposite to each other, and the arc plates 163 drive the sponge blocks 164 to move downward. In the process of the sponge blocks 164 moving downward, the sponge blocks 164 wipe the spiral groove of the screw 9, so that a large number of dust particles and metal particles will not be accumulated in the spiral groove of the screw 9, so as to avoid the accumulation of a large number of dust particles and metal particles in the spiral groove of the screw 9 when the gas purification device is purifying the air, causing the screw 9 to be easily aged and damaged.

[0032] On the middle of the left side of the cross bar 161, a square plate 165 is fixedly installed. A sliding rod 166 is installed through and slidably on the top surface of the square plate 165. A rubber pad 167 is fixedly installed on the bottom surface of the sliding rod 166. A circular plate 168 is fixedly installed on the top surface of the sliding rod 166. A spring 169 is fixedly installed on the bottom surface of the circular plate 168. One end of the spring 169 away from the circular plate 168 is fixedly connected to the top surface of the square plate 165. During the downward movement of the rubber pad 167, it contacts the cylinder shell 1. Under the action of the extrusion force, the sliding rod 166 slides upward in the square plate 165. The sliding rod 166 drives the circular plate 168 to move upward. The circular plate 168 drives the spring 169 to move upward. The spring 169 is stretched by the circular plate 168. Under the elastic force of the spring 169, the arc plate 163 will not bump into the cylinder shell 1 during the downward movement, avoiding that when the gas purification device purifies air, the arc plate 163 bumps into the cylinder shell 1 and causes the arc plate 163 to be easily damaged.

[0033] Two L-shaped long plates 171 are embedded on the front and back sides of the square plate 165. A U-shaped hole frame 172 is fixedly installed on the right side of the two L-shaped long plates 171. Circular openings are provided on the front and back sides of the U-shaped hole frame 172. A thin rod 173 is embedded on the bottom surface of the U-shaped hole frame 172. The bottom surface of the thin rod 173 is fixedly connected to the top surface of the scraping plate 11. A thin rod 173 is fixedly installed on the inner wall of the circular opening of the U-shaped hole frame 172. A number of arc-shaped elastic pieces 174 are fixedly installed on the outer wall of the thin rod 173. The outer walls of the number of arc-shaped elastic pieces 174 are in sliding contact with the mesh surface of the mesh frame 5. The arc-shaped elastic pieces 174 slide on the mesh surface of the mesh frame 5, causing the mesh surface of the mesh frame 5 to vibrate, so that the dust in the mesh surface gap falls off, avoiding that when the gas purification device purifies air, a large amount of dust remains in the mesh surface gap of the mesh frame 5, resulting in poor dust purification effect of the mesh surface of the mesh frame 5.

[0034] Two ring blocks 175 are fixedly installed on the outer wall of the thin rod 173. Two inclined plates 176 are respectively fixedly installed on the bottom surfaces of the two ring blocks 175. Two cushion plates 177 are respectively fixedly installed on the bottom surfaces of the two inclined plates 176. The bottom surfaces of the two cushion plates 177 are fixedly connected to the top surface of the scraping plate 11. During the downward movement of the cushion plate 177, the vibration on the thin rod 173 is transmitted to the cushion plate 177. The cushion plate 177 transmits the vibration to the scraping plate 11, causing the scraping plate 11 to vibrate and scrape off the dust particles and metal particles on the mesh surface of the mesh frame 5, avoiding that when the gas purification device purifies air, it is difficult to scrape off the dust particles and metal particles on the mesh surface cleanly, resulting in poor air intake effect of the mesh surface.

[0035] When the V-shaped frame 12 slides downward on the U-shaped rod 13, the V-shaped frame 12 drives the cross bar 161 to move downward, the cross bar 161 drives the L-shaped frame 162 to move downward, the L-shaped frame 162 drives the arc plate 163 to move downward, the arc plate 163 drives the sponge block 164 to move downward. During the downward movement of the sponge block 164, the sponge block 164 wipes the spiral groove of the screw rod 9, so that a large amount of dust particles and metal particles will not accumulate in the spiral groove of the screw rod 9, preventing a large amount of dust particles and metal particles from accumulating in the spiral groove of the screw rod 9 when the equipment is in use, thus avoiding the problem that the screw rod 9 is easily aged and damaged due to the accumulation of a large amount of dust particles and metal particles in the spiral groove of the screw rod 9 when the gas purification device purifies air.

[0036] While the V-shaped frame 12 drives the cross bar 161 to move downward, the cross bar 161 drives the square plate 165 to move downward, the square plate 165 drives the sliding rod 166 to move downward, the sliding rod 166 drives the rubber pad 167 to move downward. During the downward movement of the rubber pad 167, it contacts the cylinder shell 1. Under the action of the extrusion force, the sliding rod 166 slides upward in the square plate 165, the sliding rod 166 drives the round plate 168 to move upward, the round plate 168 drives the spring 169 to move upward, and the spring 169 is stretched by the round plate 168. Under the elastic force of the spring 169, the arc plate 163 will not bump into the cylinder shell 1 when moving downward, preventing the arc plate 163 from bumping into the cylinder shell 1 when the equipment is in use, thus avoiding the problem that the arc plate 163 is easily damaged due to the arc plate 163 bumping into the cylinder shell 1 when the gas purification device purifies air.

[0037] While the cross bar 161 drives the square plate 165 to move downward, the square plate 165 drives the L-shaped long plate 171 to move downward, the L-shaped long plate 171 drives the U-shaped hole frame 172 to move downward. At the same time, the thin rod 173 supports the U-shaped hole frame 172, the U-shaped hole frame 172 drives the thin rod 173 to move downward, the thin rod 173 drives the arc-shaped elastic piece 174 to move downward, and the arc-shaped elastic piece 174 slides on the mesh surface of the mesh frame 5, causing the mesh surface of the mesh frame 5 to vibrate, shaking off the dust in the mesh surface gaps, preventing a large amount of dust from remaining in the mesh surface gaps of the mesh frame 5 when the equipment is in use, thus avoiding the problem that the dust purification effect of the mesh surface of the mesh frame 5 is poor due to a large amount of dust remaining in the mesh surface gaps of the mesh frame 5 when the gas purification device purifies air.

[0038] While the U-shaped hole frame 172 drives the thin rod 173 to move downward, the thin rod 173 drives the ring block 175 to move downward, the ring block 175 drives the inclined plate 176 to move downward, and the inclined plate 176 drives the backing plate 177 to move downward. During the downward movement of the backing plate 177, the vibration on the thin rod 173 is transmitted to the backing plate 177, and the backing plate 177 transmits the vibration to the scraper 11, causing the scraper 11 to vibrate and scrape off the dust particles and metal particles on the mesh surface of the mesh frame 5, preventing the equipment from being difficult to scrape off the dust particles and metal particles on the mesh surface during use, thereby avoiding the problem that the gas purification device is difficult to scrape off the dust particles and metal particles on the mesh surface during air purification, resulting in poor air intake effect of the mesh surface.
