[0009] Furthermore, the sealing plate passes through the interior of the upper filter plate, and the bottom of the sealing plate is in contact with the surface of the strapping plate.

[0010] Furthermore, the receiving hopper is connected to the filtering and purification box, and the opening for the connection is located on the surface of the board at a relatively low height.

[0011] Furthermore, activated carbon particles are filled between the lower filter plate and the upper filter plate, and the outer diameter of the activated carbon particles is larger than the pore size of the surface of the lower filter plate and the upper filter plate.

Finally, new activated carbon particles enter between the lower filter plate and the upper filter plate. At this time, under the vibration of the lower filter plate, the new activated carbon particles can be tightly precipitated between the lower filter plate and the upper filter plate.

[0018] 2. The compressed air purification equipment for industrial gas production, when the compressed air enters the filter purification box, the flow effect pushes the suspended rubber ball to rise and fall in the air, thereby causing the other end of the linkage rod to rise and fall accordingly, and through the tightened wire rope, the lower filter plate is driven to oscillate slightly and at high frequency. The slight and high-frequency oscillation of the lower filter plate can loosen the activated carbon particles and prevent the activated carbon particles from becoming compacted.

[0026] like Figure 1-Figure 5As shown, the present invention provides a technical solution: a compressed air purification device for industrial gas production, including a filter purification box 1 and a filter assembly 4, the bottom of the outer wall of the filter purification box 1 is provided with a surrounding pipe 2, and the inner side of the surrounding pipe 2 is provided with an injection pipe 3, the filter assembly 4 is arranged on the upper part of the inner wall of the filter purification box 1, the filter assembly 4 includes an upper filter plate 401, a strap plate 402, a spring airbag 403, a lower filter plate 404, an electric push rod 405, a sealing plate 406, a receiving hopper 407, a support plate frame 408, a linkage rod 409, a rubber ball 410 and a wire rope 411, the upper filter plate 401 On both sides below the filter purification box 1, there are fixed straps 402 on the inner wall, and spring air bags 403 are arranged at the concave edges of the straps 402. The surface of the spring air bags 403 is connected to the lower filter hole plate 404. Electric push rods 405 are fixed on the inner wall of the filter purification box 1 above both sides of the upper filter hole plate 401, and a sealing plate 406 is fixed to the bottom of the electric push rods 405. A hopper 407 is arranged on one side of the filter purification box 1, and the bottom of the hopper 407 is connected to the activated carbon regeneration equipment through a pipeline. A support frame 408 is fixed to the outer wall of one end of the gas injection pipe 3 inside the filter purification box 1, and the support frame 408 The top is rotatably connected with a linkage rod 409, the bottom end of the linkage rod 409 is connected with a rubber ball 410, and the end of the linkage rod 409 away from the rubber ball 410 is connected with a wire rope 411, the upper filter plate 401 is fixedly connected to the inner wall of the filtration purification box 1, and the upper filter plate 401 and the lower filter plate 404 are distributed in parallel, the straps 402 are staggered up and down, and the lower filter plate 404 is elastically connected to the straps 402 through the spring airbag 403, the sealing plate 406 runs through the interior of the upper filter plate 401, and the bottom of the sealing plate 406 is in contact with the surface of the strap 402, and the receiving hopper 407 is connected to the upper filter plate 401. The filtration and purification box 1 is connected, and the common opening position is located on the surface of the relatively low-height take-up plate 402. Activated carbon particles are filled between the lower filter plate 404 and the upper filter plate 401, and the outer diameter of the activated carbon particles is larger than the aperture size of the lower filter plate 404 and the upper filter plate 401. The top of the steel wire rope 411 is connected to the bottom of the lower filter plate 404, and the lower filter plate 404 is connected to the rubber ball 410 through the steel wire rope 411 and the linkage rod 409. The rubber ball 410 is located at the outlet end of the gas injection pipe 3, and the center height of the rubber ball 410 is higher than the center height of the gas injection pipe 3.

[0027] The specific operation is as follows: compressed air is injected into the surrounding tube 2 through the three-way valve, and the compressed air is discharged from the air injection pipes 3 along the surrounding tube 2 into the filter purification box 1. During the air discharge process, the rubber ball 410 is pushed up and down in the air, and the other end of the linkage rod 409 is driven to rise and fall during the rising and falling process, and the lower filter plate 404 is driven to oscillate slightly at a high frequency by the tightened wire rope 411. When the lower filter plate 404 oscillates, the spring airbags 403 at the bottom of both sides are forced to expand and contract accordingly, thereby making the lower filter plate 404 stable on the surface of the strap 402. When the lower filter plate 404 oscillates, its side surface is always in close contact with the side of the concave edge of the strap 402, and activated carbon particles are filled between the lower filter plate 404 and the upper filter plate 401. When the lower filter plate 404 oscillates slightly at a high frequency, the activated carbon particles can be loosened, so that the compressed air is fully in contact with the activated carbon particles during the rising process to adsorb and filter impurities in the air, so as to play an air purification role and avoid the activation carbon particles from becoming compacted;

[0028] When the compressed air rises for purification, the electric push rod 405 extends so that the bottom of the sealing plate 406 fits with the surface of the strap 402, thereby preventing the activated carbon particles from leaking during the oscillation process;

[0029] When the activated carbon particles between the lower filter plate 404 and the upper filter plate 401 are saturated with adsorption, the relatively low electric push rod 405 contracts to lift the sealing plate 406, and the top opening of the receiving hopper 407 is exposed. At this time, the activated carbon particles move downward along the slightly inclined surface of the lower filter plate 404 under the action of the slightly high-frequency oscillation of the lower filter plate 404 until the activated carbon particles enter the receiving hopper 407. Finally, the activated carbon particles are transferred to the activated carbon regeneration equipment through the transmission pipeline for regeneration treatment;

[0030] Based on the above description, the flow action of the compressed air when entering the filtration and purification box 1 of the present invention pushes the suspended rubber ball 410 to rise and fall in the air, thereby causing the other end of the connecting rod 409 to rise and fall accordingly, and the lower filter plate 404 is driven by the taut wire rope 411 to oscillate slightly at a high frequency, and the slight high-frequency oscillation of the lower filter plate 404 can loosen the activated carbon particles and prevent the activated carbon particles from becoming compacted. Secondly, when the activated carbon particles need to be replaced, it is only necessary to open the sealing plate 406 to expose the top opening of the receiving hopper 407. At this time, under the action of the slight high-frequency oscillation of the lower filter plate 404, the activated carbon particles move downward along the slightly inclined surface of the lower filter plate 404 until the activated carbon particles enter the receiving hopper 407, thereby realizing the rapid discharge of the activated carbon.

[0031] like Figure 1-Figure 5As shown, a Jiaolong lifting component 5 is provided on the side of the filtering and purifying box 1 away from the receiving hopper 407, and the Jiaolong lifting component 5 includes a feeding channel 501 and a lifting pipe 502, and the two ends of the feeding channel 501 are respectively connected to the inside of the filtering and purifying box 1 and the lifting pipe 502, and the end of the feeding channel 501 away from the filtering and purifying box 1 is connected to the upper outer part of the lifting pipe 502, and the Jiaolong lifting component 5 also includes a Jiaolong motor 503 and a storage box 504, the bottom end of the lifting pipe 502 is connected to the storage box 504, and the side of the storage box 504 is connected to the activated carbon regeneration equipment through a pipeline, and the top of the lifting pipe 502 is provided with a Jiaolong motor 503, and the bottom output end of the Jiaolong motor 503 is connected to the Jiaolong shaft inside the lifting pipe 502;

[0032] The specific operation is as follows: when it is necessary to fill new activated carbon particles between the lower filter plate 404 and the upper filter plate 401, the relatively low electric push rod 405 extends to close the top opening of the receiving hopper 407, and the relatively high electric push rod 405 contracts to open the feed channel 501, and the regenerated activated carbon particles are transferred from the activated carbon regeneration equipment to the storage box 504 through the pipeline. At this time, the dragon motor 503 drives the dragon shaft to rotate to transfer the activated carbon particles in the storage box 504 upward along the lifting pipe 502, and finally the activated carbon particles enter between the lower filter plate 404 and the upper filter plate 401 along the feed channel 501. At this time, under the vibration of the lower filter plate 404, the new activated carbon particles can be tightly precipitated between the lower filter plate 404 and the upper filter plate 401.

[0033] In summary, when the compressed air purification equipment for industrial gas production is used, the compressed air is first injected into the surrounding pipe 2 through the three-way valve, and the compressed air is discharged from the air injection pipes 3 along the surrounding pipe 2 to the inside of the filter purification box 1. During the air discharge process, the rubber ball 410 is pushed to rise and fall in the air, and the other end of the linkage rod 409 is driven to rise and fall during the rising and falling process, and the lower filter plate 404 is driven to oscillate slightly with high frequency by the tightened wire rope 411. When the lower filter plate 404 oscillates, the spring airbags 403 at the bottom of both sides are stretched accordingly. The lower filter plate 404 is shrunk, thereby making the lower filter plate 404 stable to vibrate on the surface of the strap 402, and when the lower filter plate 404 vibrates, its side surface is always in close contact with the side of the concave edge of the strap 402, and the lower filter plate 404 and the upper filter plate 401 are filled with activated carbon particles, and when the lower filter plate 404 vibrates slightly at a high frequency, the activated carbon particles can be loosened, so that the compressed air can fully contact with the activated carbon particles during the rising process to adsorb and filter impurities in the air, so as to play an air purification role and avoid the activated carbon particles from becoming compacted;

[0034] When the compressed air rises for purification, the electric push rod 405 extends so that the bottom of the sealing plate 406 fits with the surface of the strap 402, thereby preventing the activated carbon particles from leaking during the oscillation process;

[0035] When the activated carbon particles between the lower filter plate 404 and the upper filter plate 401 are saturated with adsorption, the relatively low electric push rod 405 contracts to lift the sealing plate 406, and the top opening of the receiving hopper 407 is exposed. At this time, the activated carbon particles move downward along the slightly inclined surface of the lower filter plate 404 under the action of the slightly high-frequency oscillation of the lower filter plate 404 until the activated carbon particles enter the receiving hopper 407. Finally, the activated carbon particles are transferred to the activated carbon regeneration equipment through the transmission pipeline for regeneration treatment;

[0036] When it is necessary to fill new activated carbon particles between the lower filter plate 404 and the upper filter plate 401, the relatively low electric push rod 405 extends to close the top opening of the receiving hopper 407, and the relatively high electric push rod 405 contracts to open the feed channel 501, and the regenerated activated carbon particles are transferred from the activated carbon regeneration equipment to the storage box 504 through a pipeline. At this time, the dragon motor 503 drives the dragon shaft to rotate to transfer the activated carbon particles in the storage box 504 upward along the lifting pipe 502, and finally the activated carbon particles enter between the lower filter plate 404 and the upper filter plate 401 along the feed channel 501.
