Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dust removal machinery, in particular to a dust removal device for grouting material production. BACKGROUND

[0002] Grouting material is a new type of building material made of cement as base material, combined with quartz sand, fly ash, admixture and other raw materials, and mixed and stirred, which is mainly used for building structure reinforcement, equipment installation leveling, crack repair and other scenes.

[0003] The finished grouting material is in the form of fine particle powder, and dust is easily generated during filling and conveying. The fine powder dust is easily floating and adhered to the outside of the material guide pipe and the opening of the packaging bag.

[0004] During the production of grouting material, the prior art fills the powder into the packaging bag through automatic equipment. After filling is completed, the filling pipe needs to be removed. However, during filling, the powder will scatter and adhere to the outer wall of the filling pipe. Exposure to the air will cause the dust of this part to pollute the environment of the production area. When filling again, the packaging bag will be contacted, causing the packaging bag to adhere to the dust. In addition, after the packaging bag is filled, there will be a residual space inside the packaging bag. When stacking, transporting or transferring, the residual space of the packaging bag is extruded, causing the dust inside the packaging bag to be discharged outward, again causing pollution. Therefore, we propose a dust removal device for grouting material production to solve the above problems. SUMMARY

[0007] The packaging powder removing mechanism comprises an absorbing box fixedly installed on the side of the frame body, the absorbing box is close to the lower side of the material guide pipe, a impeller is rotatably arranged in the absorbing box, a driving motor two is arranged on the back of the absorbing box, a belt pulley set is drivingly connected to the output end of the driving motor two, the belt pulley at one end of the belt pulley set is fixedly connected with the impeller, and the belt pulley at the other end of the belt pulley set is fixedly connected with a first clamping piece.

[0008] A dust collector one is connected to the bottom of the absorbing box, and a filter screen is fixedly connected to the top of the dust collector one.

[0009] Preferably, the material pipe dust removing mechanism comprises installation arms symmetrically arranged on the two sides of the material guide pipe, a spring one is movably sleeved and installed on the installation arm, a dust removing ring is slidably arranged on the installation arm, one side of the dust removing ring is abutted with the spring one, a second clamping piece is rotatably connected to the bottom of the dust removing ring, and the second clamping piece is movably clamped with the first clamping piece.

[0010] Preferably, a gear is fixedly connected to the second clamping piece, a rotating ring is rotatably sleeved in the dust removing ring, a tooth ring is fixedly connected to the side surface of the rotating ring, and the tooth ring is engaged with the gear.

[0011] Preferably, a plurality of grooves are circumferentially arranged on the rotating ring, a sweeping piece is arranged on the side surface of the groove, the number of the sweeping pieces is matched with the number of the grooves, and the end of the sweeping piece is in frictional contact with the outer edge of the material guide pipe.

[0012] Preferably, a dust collector two is fixedly installed on the side surface and bottom of the dust removing ring, and the dust collector two is in communication with the inside of the dust removing ring.

[0013] Preferably, vertical columns are symmetrically installed on the top of the sliding table, a top frame is fixedly connected to the top of the vertical column, an electric cylinder two is arranged on the top frame, a pressing frame is fixedly connected to the output end of the electric cylinder two, and the pressing frame is slidably connected with the vertical column.

[0014] Preferably, a plurality of top pressing rollers are fixedly installed on the top inner edge of the pressing frame, and side pressing rollers are movably installed on the two sides of the pressing frame.

[0016] Preferably, fixed blocks are fixedly connected to the two sides of the top of the frame body, and the fixed blocks are abutted with the movable blocks.

[0017] Compared with the prior art, the present application has the following advantages:

[0018] In this invention, after filling is completed, the packaging dust removal mechanism and the material pipe dust removal mechanism are linked. The second drive motor drives the pulley group to drive the impeller and the first clamping tooth to rotate synchronously. On the one hand, the sweeping blade rotates around the guide pipe to completely sweep off the dust attached to the outer wall of the guide pipe. On the other hand, the dust collector collects the swept dust to prevent the dust from being exposed to the air and polluting the production area. At the same time, as the moving table moves the packaging bag away from the guide pipe, the dust removal mechanism continues to operate to ensure that no dust falls off after the guide pipe is detached. This also avoids the problem of dust on the outer wall of the guide pipe contacting the packaging bag during subsequent filling, causing dust to adhere to the packaging bag, and ensuring that the packaging bag has a clean appearance.

[0019] In this invention, after filling is completed, the device uses a venting mechanism to uniformly squeeze the packaging bag from the top and sides, preemptively expelling any residual space inside the packaging bag and preventing dust from overflowing during subsequent stacking, transportation, or transfer. Simultaneously, during the venting process, the packaging dust removal mechanism operates continuously, using the negative pressure generated by the absorption box to suck in and filter all the dust-laden gas discharged during venting. The dust is then collected centrally by a dust collector, reducing dust pollution during packaging bag compression and achieving environmentally friendly dust removal. Attached Figure Description

[0035] 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.

[0036] Please see Figures 1 to 8 The present invention provides a technical solution: including a loading machine 1, a guide pipe 2 on the loading machine 1, a control mechanism 3 on the side of the loading machine 1, a packaging powder removal mechanism 4 and an emptying mechanism 6 on the control mechanism 3, and a material pipe dust removal mechanism 5 on the loading machine 1.

[0037] The control mechanism 3 includes a machine base 301 set on the side of the loading machine 1. A drive motor 302 is set in the middle of the machine base 301. A lead screw 303 is rotatably installed at the output end of the drive motor 302. A slide table 304 is slidably set on the machine base 301. The slide table 304 is connected to the lead screw 303. A moving table 305 is slidably set on the top of the slide table 304. An electric cylinder 306 is connected to one side end of the moving table 305. The output shaft of the electric cylinder 306 is fixedly connected to the moving table 305. A frame 307 is fixedly installed on the top of the moving table 305. A hydraulic cylinder 308 is set inside the frame 307. A top seat 309 is connected to the top of the hydraulic cylinder 308.

[0038] In this embodiment, the control mechanism 3 is activated, and the drive motor 302 drives the lead screw 303 to rotate, so that the slide table 304 slides along the machine table 301 to directly below the guide pipe 2. The electric cylinder 306 retracts, driving the moving table 305 and the top frame 307, hydraulic cylinder 308, and top seat 309 to reset, ensuring that the absorption box 401 is aligned with the bottom of the guide pipe 2. The hydraulic cylinder 308 retracts, and the top seat 309 is in a low position, which is convenient for placing the packaging bag. The grout packaging bag is placed on the top seat 309, and the opening of the packaging bag is adjusted to align with the outlet of the guide pipe 2. The hydraulic cylinder 308 is activated to push the top seat 309 to rise, so that the opening of the packaging bag is aligned with the end of the guide pipe 2.

[0039] The packaging powder removal mechanism 4 includes an absorption box 401 fixedly installed on the side of the frame 307. The absorption box 401 is located near the bottom of the guide pipe 2. An impeller 402 is rotatably installed inside the absorption box 401. A second drive motor 403 is installed on the back of the absorption box 401. A pulley group 404 is connected to the output end of the second drive motor 403. One pulley of the pulley group 404 is fixedly connected to the impeller 402. A toothed component 405 is fixedly connected to the pulley of the other end of the pulley group 404.

[0040] The bottom of the absorption box 401 is connected to a dust collector 406, and the top of the dust collector 406 is fixedly connected to a filter screen 407.

[0041] The dust removal mechanism 5 of the material pipe includes mounting arms 501 symmetrically arranged on both sides of the guide pipe 2. A spring 502 is movably sleeved on the mounting arm 501. A dust removal ring 503 is slidably arranged on the mounting arm 501. One side of the dust removal ring 503 abuts against the spring 502. A second locking tooth 504 is rotatably connected to the bottom of the dust removal ring 503. The second locking tooth 504 is movably locked with the first locking tooth 405.

[0042] A gear 505 is fixedly connected to the second gear component 504. A rotating ring 506 is rotatably sleeved inside the dust removal ring 503. A toothed ring 507 is fixedly connected to the side of the rotating ring 506. The toothed ring 507 meshes with the gear 505.

[0043] The rotating ring 506 has several empty slots 508. The side of the empty slots 508 is provided with a sweeping blade 509. The number of sweeping blades 509 is matched with the number of empty slots 508. The end of the sweeping blade 509 is in frictional contact with the outer edge of the guide tube 2.

[0044] A second dust collector 510 is fixedly installed on the bottom side of the dust collector ring 503, and the second dust collector 510 is in communication with the interior of the dust collector ring 503.

[0045] In this embodiment, after the packaging bag is positioned, the filling machine 1 is started. The filling machine 1 conveys the grouting material into the packaging bag at a constant speed through the guide pipe 2. When the grouting material in the packaging bag reaches the preset weight, the filling machine 1 stops conveying the grouting material. At this time, the packaging dust removal mechanism 4 and the material pipe dust removal mechanism 5 are started synchronously. First, the moving table 305 slides outward, and the packaging bag moves away from the guide pipe 2 synchronously. During the process, the second drive motor 403 is started. The second drive motor 403 drives the impeller 402 through the pulley group 404 to move the absorption box 4. The high-speed rotation inside box 401 generates negative pressure, drawing in all the residual grout dust at the opening of the packaging bag and any dust that did not overflow during the filling process. The dust is then filtered by filter screen 407, where large particles are intercepted, while fine dust enters dust collector 406 for centralized collection, achieving initial removal of dust around the packaging bag. Simultaneously, the pulley assembly 404 rotates, and the locking tooth component 405 fixed at its other end rotates synchronously. Because locking tooth component 405 is movably engaged with locking tooth component 504, locking tooth component 405... 405 drives the second toothed component 504 to rotate synchronously. The second toothed component 504 drives the gear 505 fixed on its surface to rotate. The gear 505 meshes with the toothed ring 507 on the side of the rotating ring 506, thereby driving the rotating ring 506 to rotate inside the dust removal ring 503. When the rotating ring 506 rotates, the sweeping blade 509 on the side of its upper slot 508 rotates synchronously around the guide pipe 2. The end of the sweeping blade 509 rubs against the outer edge of the guide pipe 2, sweeping off the grouting material dust attached to the outside of the guide pipe 2. The swept-off dust enters the dust removal ring. Inside 503, dust collector 2 510, which is connected to dust collector ring 503, sucks in and collects the dust, achieving preliminary cleaning of the dust on the outside of guide tube 2. When the moving table 305 moves, it drives the absorption box 401 and the first clamping tooth 405 to move synchronously. The first clamping tooth 405 drives the second clamping tooth 504 and dust collector ring 503 to slide along the mounting arm 501. The first spring 502 adapts to the moving position of dust collector ring 503 to ensure that the sweeping plate 509 is always in close contact with the outer edge of guide tube 2, ensuring the dust removal effect.

[0046] The top of the slide table 304 is symmetrically equipped with columns 601, and the top of the column 601 is fixedly connected to the top of the top frame 602. The top frame 602 is equipped with an electric cylinder 603, and the output end of the electric cylinder 603 is fixedly connected to the pressure frame 604. The pressure frame 604 is slidably connected to the column 601.

[0047] Several top pressure rollers 605 are fixedly installed on the top inner edge of the pressure frame 604, and side pressure rollers 606 are movably installed on both sides of the pressure frame 604.

[0048] The side pressure roller 606 passes through the pressure frame 604 and is fixedly connected to the movable block 607. A spring 608 is movably sleeved between the movable block 607 and the side pressure roller 606.

[0049] Fixed blocks 609 are fixedly connected to the top two sides of the frame 307, and the fixed blocks 609 abut against the movable blocks 607;

[0050] In this embodiment, after the packaging bag is completely detached from the guide tube 2 and moves to the preset emptying station, the top seat 309 moves downward so that the opening of the packaging bag faces the absorption box 401. The emptying mechanism 6 is activated to squeeze and empty the packaging bag. At the same time, the packaging dust removal mechanism 4 continues to operate to absorb the dust-laden gas generated during the emptying process. The electric cylinder 603 is controlled to continue to push the pressure frame 604 downward. The top pressure roller 605 further squeezes the top of the packaging bag. At the same time, the movable block 607 and the fixed block 609 further abut against each other. The side pressure roller 606 is under the elastic force of the spring 608. The packaging bag is squeezed simultaneously from both sides. The top pressure roller 605 and the side pressure roller 606 work together to squeeze the packaging bag evenly from the top and both sides, expelling excess gas from the packaging bag and facilitating subsequent packaging and sealing. When the packaging bag is squeezed and emptied, some grout dust will be mixed in with the gas. At this time, the absorption box 401 is aligned with the opening of the packaging bag, and the negative pressure generated by the impeller 402 will draw all the dust-laden gas into the absorption box 401. After being filtered by the filter screen 407, the dust enters the dust collector 406 for collection, and the purified gas is discharged to prevent the dust-laden gas from spreading and polluting the environment.

[0051] In this embodiment, after the evacuation is completed, the drive motor 403, dust collector 406, and dust collector 510 are turned off. The impeller 402, rotating ring 506, and sweeping blade 509 stop running. The electric cylinder 603 is started to retract, which drives the pressure frame 604 to rise along the column 601. The top pressure roller 605 and the side pressure roller 606 are separated from the packaging bag. The movable block 607 is separated from the fixed block 609. The side pressure roller 606 is reset under the action of the spring 608. The hydraulic cylinder 308 is started to retract, which drives the top seat 309 to descend. The staff takes out the processed packaging bag.

[0052] The method of use and advantages of the present invention: The working process of this dust removal device for grout production is as follows:

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown:

[0054] S1: Activate control mechanism 3. Drive motor 302 drives screw 303 to slide slide table 304 directly below guide tube 2. Electric cylinder 306 retracts, resetting the moving table 305 and related components to ensure absorption box 401 is aligned with the bottom of guide tube 2. Hydraulic cylinder 308 retracts, lowering top seat 309. Place packaging bag and adjust opening to align with guide tube 2 outlet. Then activate hydraulic cylinder 308 to push top seat 309 upward, aligning packaging bag opening with end of guide tube 2.

[0055] S2: Start the loading machine 1, which feeds the packaging bag at a uniform speed through the guide pipe 2. After reaching the preset weight, the loading machine 1 stops. Simultaneously, the packaging dust removal mechanism 4 and the material pipe dust removal mechanism 5 are started. The moving table 305 slides outward, moving the packaging bag away from the guide pipe 2. At the same time, the drive motor 403 drives the impeller 402 to rotate through the pulley group 404, generating negative pressure to suck the dust from the opening of the packaging bag into the absorption box 401. After being filtered by the filter screen 407, the dust is collected by the dust collector 406. The pulley group 404 simultaneously drives the first toothed component 405 and the second toothed component 504 to rotate. Through the meshing of the gear 505 and the toothed ring 507, the rotating ring 506 is driven to rotate. The sweeping blade 509 rotates around the guide pipe 2 to sweep off the dust, which is collected by the dust collector 510. When the moving table 305 moves, the dust removal ring 503 slides along the mounting arm 501, and the spring 502 adapts to extend and retract, ensuring that the sweeping blade 509 is in contact with the guide pipe 2.

[0056] S3: After the packaging bag is completely separated from the guide pipe 2 and reaches the emptying station, the top seat 309 moves down so that the opening of the packaging bag faces the absorption box 401. The electric cylinder 603 pushes the pressure frame 604 down, the top pressure roller 605 squeezes the top of the packaging bag, and the movable block 607 abuts against the fixed block 609 so that the side pressure roller 606 squeezes from both sides to discharge the excess gas in the bag. The packaging dust removal mechanism 4 continues to operate, sucking the dust-containing gas discharged during the emptying into the absorption box 401. After being filtered by the filter screen 407, it is collected by the dust collector 406 to prevent dust from spreading.

[0057] In this invention, after filling is completed, the packaging dust removal mechanism 4 and the material pipe dust removal mechanism 5 are linked together. The second drive motor 403 drives the pulley group 404 to drive the impeller 402 and the first clamping tooth 405 to rotate synchronously. On the one hand, the sweeping blade 509 rotates around the guide pipe 2 to completely sweep off the dust attached to the outer wall of the guide pipe 2. On the other hand, the dust collector 510 collects the swept dust to prevent the dust from being exposed to the air and polluting the production area. At the same time, as the moving table 305 moves the packaging bag away from the guide pipe 2, the dust removal mechanism continues to operate to ensure that no dust falls off after the guide pipe 2 is detached. This also avoids the problem of dust on the outer wall of the guide pipe 2 contacting the packaging bag and causing dust to adhere to the packaging bag during subsequent filling, thus ensuring that the packaging bag has a clean appearance.

[0058] In this invention, after filling is completed, the device uses the venting mechanism 6 to uniformly squeeze the packaging bag from the top and sides, expelling the residual space inside the packaging bag in advance, thus preventing dust from overflowing during subsequent stacking, transportation, or transfer. At the same time, during the venting process, the packaging dust removal mechanism 4 continues to operate, using the negative pressure generated by the absorption box 401 to suck in and filter all the dust-laden gas discharged during venting. The dust is collected by the dust collector 406, reducing dust pollution during packaging bag compression and achieving environmentally friendly dust removal.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
