Deodorizing and desilting device

Abstract

This invention discloses a deodorizing and sludge-unloading device, belonging to the field of deodorization technology. It addresses the problem of reduced efficiency of the air pump, which prevents the rapid extraction of odors, causing them to overflow and pollute the air. The device includes a top plate, with an inner cover fixed to its bottom surface. An air pump is fixed to the top of one side of the inner cover's inner wall, with its output end passing through the top plate. A mounting bucket is fixed to the top of one side of the inner cover's outer wall, and a winding shaft is installed inside the mounting bucket. The invention utilizes contact strips to smooth out wrinkles on the surface of the shielding film, facilitating a complete seal between the shielding film and the inner cover. A spring ensures the bottom of the shielding film is stably engaged in the bottom groove, effectively sealing the inlet of the inner cover. This prevents the air pump from becoming less efficient after prolonged use, thus avoiding the leakage of odors from the connection between the inner cover and the roller shutter door, which would otherwise pollute the air.

Description

Technical Field

[0001] This invention belongs to the field of deodorization technology, specifically relating to a deodorization and sludge unloading device. Background Technology

[0002] Existing deodorizing and sludge unloading devices work by pouring sludge into the inner shroud, then pulling the roller shutter to block the shroud's inlet. An air pump is then activated to extract the odor from the sludge. However, because the roller shutter is composed of multiple connected strips, it cannot completely block the shroud's inlet. When the air pump is working normally, the odor inside the shroud can be quickly extracted, preventing it from escaping to the outside through the connection between the roller shutter and the shroud. But when the air pump is used for a long time, its extraction efficiency gradually decreases. At this point, the air pump cannot extract the odor quickly, causing it to overflow from the connection between the roller shutter and the shroud, polluting the air.

[0003] Therefore, a deodorizing and sludge unloading device is needed to solve the problem in existing technologies where the efficiency of the air pump decreases, making it impossible to quickly extract the odor, causing the odor to overflow to the outside and pollute the air.

A winding shaft is provided inside the installation bucket 201. Rotating shafts 204 are fixed to both ends of the winding shaft. A shielding film 203 is wound up on the outer wall of the winding shaft. One end of the shielding membrane 203 is fixed with a counterweight strip 202. Positioning posts 301 are fixed on both sides of the top of one side of the outer wall of the inner cover 200. A movable strip 300 is movably connected between the two positioning posts 301. Several evenly distributed stabilizing posts 801 are fixed to the movable strip 300 near the side of the inner cover 200. Several evenly distributed stabilizing holes 800 are opened on the top of one side of the outer wall of the inner cover 200. Semicircular openings are respectively opened on both sides of one side of the outer wall of the inner cover 200. A cylindrical groove 308 has an inner hole 900 on the top surface of its inner sidewall. Two positioning posts 301 have stop bars 302 fixed to one end, and a connecting strip 303 is provided between the two stop bars 302. A fixing frame 304 is fixed to one side of each stop bar 302, and one side of the fixing frame 304 is fixed to one side of the stop bar 302. A winding wheel 305 is movably connected inside the fixing frame 304, and a connecting rope 307 is provided on the outer wall of the winding wheel 305. Two second servo motors 306 are fixed to one side of the connecting strip 303. The output end of the second servo motor 306 is fixed to the shaft of the take-up wheel 305. Two mounting posts 500 are fixed to the bottom surface of the movable strip 300. A smoothing rod 501 is movably connected between the two mounting posts 500. A slot 502 is opened on one side of the smoothing rod 501 near the inner cover 200. A contact strip 504 is provided in the slot 502. A bottom groove 902 is opened at the bottom of one side of the inner cover 200.

[0045] As a further embodiment of the present invention, the movable strip 300 has openings 600 on both sides of one side, and a pulley 601 is fixed on one side of the inner wall of the opening 600, and the connecting rope 307 passes through the pulley 601.

[0046] The pulley 601 allows the connecting rope 307 to be turned, which facilitates the downward movement of the connecting rope 307 and makes it easier for the connecting rope 307 to engage with the semi-cylindrical groove 308.

[0047] As a further embodiment of the present invention, mounting rods 309 are fixed on both sides of the smoothing rod 501 away from the inner cover 200, a first magnet 310 is fixed at the bottom of the connecting rope 307, a T-shaped groove 311 is provided on one side of the first magnet 310, and a T-shaped block 312 is fixed at one end of the mounting rod 309, the T-shaped block 312 is movably engaged in the T-shaped groove 311.

[0048] The T-slot 311 and T-block 312 allow the position of the first magnet 310 to be movably limited. The first magnet 310 allows the connecting rope 307 to be moved by the first magnet 310, and at the same time facilitates the connection between the first magnet 310 and the second magnet 314. The connecting rope 307 tightly presses the shielding film 203 into the semi-cylindrical groove 308, so that the shielding film 203 seals the inner cover 200.

[0049] As a further embodiment of the present invention, the inner cover 200 has mounting grooves 313 on both sides of the bottom of one side, and a second magnet 314 is fixed in the mounting groove 313. The second magnet 314 and the first magnet 310 are arranged with the same polarity at one end close to each other.

[0050] The installation groove 313 is used to fix the position of the second magnet 314. The second magnet 314 is used to connect the first magnet 310 to the second magnet 314, so that the connecting rope 307 presses the shielding film 203 tightly into the semi-cylindrical groove 308, so that the shielding film 203 seals the inner cover 200.

[0051] As a further embodiment of the present invention, a connecting frame 400 is fixed to the middle of the side of the movable strip 300 away from the inner cover 200, a fixing strip 402 is fixed to the outer wall of the mounting barrel 201, a threaded rod 401 is movably connected to the bottom of one side of the fixing strip 402, the connecting frame 400 is movably connected to the outer wall of the threaded rod 401, an L-shaped rod 406 is fixed to the outer wall of the mounting barrel 201, a third servo motor 405 is fixed to one side of the L-shaped rod 406, a second pulley 403 is fixed to the output end of the third servo motor 405 and a non-threaded position on one side of the outer wall of the threaded rod 401, and a second belt 404 is movably connected between the two second pulleys 403.

[0052] The threaded rod 401 and the connecting bracket 400 are configured so that when the threaded rod 401 rotates, the connecting bracket 400 can move, thereby driving the movable bar 300 to move.

[0053] This solution has the following working process: When sealing the inner cover 200, if it is necessary to remove the odor from the mud, firstly, the mud is poured into the inner cover 200. Then, the PLC controller 315 is operated, and the PLC controller 315 starts the first servo motor 208. The rotation of the first servo motor 208 drives the rotating shaft 204 to rotate through the transmission of the first pulley 205 and the first belt 206, which in turn drives the winding shaft to rotate. At this time, the shielding film 203 moves off the winding shaft under the gravity of the counterweight 202 and moves downward until the shielding film 203 covers the inner cover 200. The inlet is sealed, and then the PLC controller 315 controls the third servo motor 405 to rotate. The rotation of the third servo motor 405 drives the threaded rod 401 to rotate through the transmission of the second pulley 403 and the second belt 404. The rotation of the threaded rod 401 drives the connecting frame 400 to move. The movement of the connecting frame 400 drives the movable bar 300 to move. The movement of the movable bar 300 causes the stabilizing column 801 to push the shielding membrane 203 into the stabilizing hole 800. At this time, the movable bar 300 squeezes the shielding membrane 203, so that this part of the shielding membrane 203... Connected to the outer wall of the inner cover 200, at this time, the spring 506 is compressed, and the contact strip 504 contacts the shielding film 203. Then, the fourth servo motor 705 is started, and the second servo motor 306 is started at the same time. The fourth servo motor 705 drives the rotating rod 703 to rotate, so that the winding rope 701 on the winding column 702 is released. The smoothing rod 501 drives the winding rope 701 to move down, and the contact strip 504 smooths the wrinkles on the surface of the shielding film 203. At the same time, the connecting rope 307 is released, and the first magnet 310 pulls the connecting rope 307 down. When the contact strip 504... When the shielding membrane 203 is engaged in the bottom groove 902, the bottom of the shielding membrane 203 is squeezed by the contact strip 504, sealing the position. Simultaneously, the proximal ends of the first magnet 310 and the second magnet 314 approach each other, and the first magnet 310 moves, attracting and fixing the first magnet 310 and the second magnet 314. At this time, the connecting rope 307 is driven by the first magnet 310, causing the connecting rope 307 to squeeze and engage the shielding membrane 203 in the semi-cylindrical groove 308, sealing both sides of the shielding membrane 203. Ultimately, the shielding membrane 203 tightly seals the inlet of the inner cover 200. Then, the vacuum pump 901 is activated, drawing air from the mud out of the inner cover 200 and discharging it to the appropriate location.

[0054] As can be seen from the above working process: the winding shaft, the first pulley 205, the first belt 206, and the first servo motor 208 allow the shielding film 203 to be conveniently stored in the mounting bucket 201; the movable strip 300, the stabilizing hole 800, and the stabilizing column 801 ensure that the shielding film 203 at this position can be sealed with the inner cover 200; the connecting rope 307 and the semi-cylindrical groove 308 ensure that both sides of the shielding film 203 can be sealed with the inner cover 200; and the first magnet 310 and the second magnet 314 ensure that the connecting rope 307 can tightly hold the shielding film 203 in place. The membrane 203 is pressed and engaged within the semi-cylindrical groove 308. The contact strip 504 smooths out the wrinkles on the surface of the shielding membrane 203, facilitating a complete seal between the shielding membrane 203 and the inner cover 200. The spring 506 ensures that the bottom of the shielding membrane 203 is stably engaged within the bottom groove 902, effectively sealing the inlet of the inner cover 200. This prevents the air pump 901 from becoming less efficient during prolonged use, which would otherwise prevent it from quickly removing odors and causing them to leak from the connection between the roller shutter and the inner cover 200, thus polluting the air.

[0055] As a further embodiment of the present invention, a fixing block 207 is fixed to the bottom of one side of the outer wall of the inner cover 200, a first servo motor 208 is fixed to one side of the fixing block 207, a first pulley 205 is fixed to the output end of the first servo motor 208 and the outer wall of the rotating shaft 204 on one side, and a first belt 206 is movably connected between the two first pulleys 205.

[0056] The first servo motor 208, the first pulley 205 and the first belt 206 enable the winding shaft to rotate, thereby facilitating the release of the shielding film 203 or the winding of the shielding film 203.

[0057] As a further embodiment of the present invention, top holes are respectively provided on both sides of the top surface of the movable strip 300, and side rods 704 are respectively fixed on both sides of the top surface of the movable strip 300. A rotating rod 703 is movably connected between the two side rods 704. A winding post 702 is respectively fixed on both sides of the outer wall of the rotating rod 703. A winding rope 701 is wound on the outer wall of the winding post 702. A fourth servo motor 705 is fixed on one side of the top surface of the movable strip 300. The output end of the fourth servo motor 705 is fixed to one end of the rotating rod 703. The winding rope 701 passes through the top hole. A docking block 700 is respectively fixed on both sides of the smoothing rod 501 away from the inner cover 200. One end of the winding rope 701 is fixed to the top surface of the docking block 700.

[0058] The winding post 702 and winding rope 701 allow the smoothing rod 501 to move down or up, which facilitates the contact strip 504 in smoothing the wrinkles on the surface of the masking film 203.

[0059] As a further embodiment of the present invention, mounting holes 505 are respectively provided on both sides of the side of the contact strip 504 away from the inner cover 200, and springs 506 are respectively fixed on both sides of the inner wall of the slot 502 near the inner cover 200. The springs 506 are located in the mounting holes 505. Three engaging grooves 503 are respectively provided on both sides of the inner side of the mounting groove 313, and three engaging blocks 507 are respectively fixed on both sides of the outer wall of the contact strip 504. The engaging blocks 507 are correspondingly and movably engaged in the engaging grooves 503.

[0060] By means of the spring 506, when the contact strip 504 is engaged in the bottom groove 902, the contact strip 504 can tightly engage the bottom of the shielding film 203 in the bottom groove 902. By means of the engaging groove 503 and engaging block 507, the position of the contact strip 504 can be movably limited.

[0061] As a further embodiment of the present invention, a bottom frame 101 is fixed to the bottom surface of the top plate 100, a guide rail 102 is fixed to the inner side wall of the bottom frame 101, a plurality of sliding wheels 103 are movably connected in the guide rail 102, and a shielding cloth 104 is fixed to the bottom surface of the plurality of sliding wheels 103.

[0062] The guide rail 102, sliding wheel 103 and shielding cloth 104 are designed to shield the inner cover 200 from sunlight, thus preventing the mud from being affected.

[0063] As a further embodiment of the present invention, a PLC controller 315 is fixed on the other side of the outer wall of the inner cover 200, and the first servo motor 208, the second servo motor 306, the third servo motor 405 and the fourth servo motor 705 are electrically connected to the PLC controller 315 respectively.

[0064] The PLC controller 315 enables the first servo motor 208, the second servo motor 306, the third servo motor 405, and the fourth servo motor 705 to operate in a coordinated manner.

[0065] In summary: When sealing the inner cover 200, if it is necessary to remove odors from the mud, first pour the mud into the inner cover 200. Then, operate the PLC controller 315. The PLC controller 315 starts the first servo motor 208. The rotation of the first servo motor 208 drives the rotating shaft 204 to rotate through the transmission of the first pulley 205 and the first belt 206, which in turn drives the winding shaft to rotate. At this time, the shielding film 203 moves off the winding shaft under the gravity of the counterweight 202 and moves downward until the shielding film 203 seals the inlet of the inner cover 200. Then, the PLC controller 315 controls the third servo motor 405 to rotate. The rotation of the third servo motor 405 drives the threaded rod 401 to rotate through the transmission of the second pulley 403 and the second belt 404. The rotation of the threaded rod 401 drives the connecting frame 400 to move. The movement of the connecting frame 400 drives the movable bar 300 to move. The movement of the movable bar 300 causes the stabilizing column 801 to push the shielding membrane 203 into the stabilizing hole 800. At this time, the movable bar 300 squeezes the shielding membrane 203, so that this part of the shielding membrane 203 is in contact with the inner cover 20. 0. When the outer wall is connected, the spring 506 is compressed, and the contact bar 504 contacts the shielding film 203. Then, the fourth servo motor 705 is started, and the second servo motor 306 is started at the same time. The fourth servo motor 705 drives the rotating rod 703 to rotate, so that the winding rope 701 on the winding column 702 is released. The smoothing rod 501 drives the winding rope 701 to move down. The contact bar 504 smooths the wrinkles on the surface of the shielding film 203. At the same time, the connecting rope 307 is released, and the first magnet 310 pulls the connecting rope 307 down. When the contact bar 504... When the membrane 203 is engaged in the bottom groove 902, the bottom of the shielding membrane 203 is pressed by the contact strip 504, sealing the area. Simultaneously, the proximal ends of the first magnet 310 and the second magnet 314 approach each other, and the first magnet 310 moves, attracting and fixing the second magnet 314. At this time, the connecting rope 307 is driven by the first magnet 310, causing the connecting rope 307 to press and engage the shielding membrane 203 within the semi-cylindrical groove 308, sealing both sides of the shielding membrane 203.
