Description

Technical Field

[0001] The present invention relates to the technical field of dry mortar production, and specifically relates to a dust reduction device and method for dry mortar production. Background Technique

[0002] Dry mortar refers to a granular or powdery material that is physically mixed in a certain proportion by dried and screened aggregates (such as quartz sand), inorganic binders (such as cement), and additives (such as polymers), etc., and is transported to the construction site in the form of bags or bulk, and can be directly used after adding water and mixing.

[0003] Currently, in the process of dry mortar production, each group of materials needs to be put into the mixing tank according to the appropriate ratio for mixing, and then the dry mortar required in the construction industry is obtained. During the mixing process, the raw materials are transported into the mixing tank through the action of the feeding component. When the materials are transported into the mixing tank, since the raw materials are powdery or granular, a large amount of raw material dust will be raised during the transportation process. The dust entering the production workshop will affect the workshop environment and is likely to have an impact on the health of the staff. Therefore, during the feeding process, dust reduction operations are required. In the prior art, for dust reduction, a dust collector is generally used to absorb the dust to achieve the dust reduction effect. However, after dust absorption, the collected dust will not be transported into the mixing tank, resulting in an imbalance in the proportion of raw materials, and thus may affect the quality of dry mortar. For this reason, we propose a dust reduction device and method for dry mortar production. Summary of the Invention

[0010] Preferably, the blanking assembly includes two discharging pipes. The two discharging pipes are respectively communicated with the first dust suction pipe and the second dust suction pipe. And the end of the discharging pipe communicates with a blanking pipe. The end of the blanking pipe communicates with a storage pipe. One end of the storage pipe communicates with a discharging pipe extending into the mixing tank. A baffle fixedly connected to the mixing tank is installed at the end of the discharging pipe. And a one-way sealing member is installed inside the discharging pipe.

[0011] Preferably, the one-way sealing member includes a fixing piece fixed inside the discharging pipe. A blanking hole is formed in the fixing piece. And a tension spring is fixedly connected to the fixing piece. One end of the tension spring is fixedly connected with a sealing block. The outer side of the sealing block is movably connected with a sealing ring fixedly connected to the discharging pipe.

[0012] Preferably, the cross sections of the fixing piece and the sealing ring are both conical, which is beneficial to conveying the materials inside the storage pipe into the mixing tank.

Therefore, by the forward and reverse rotation of the motor, the first dust suction pipe and the second dust suction pipe respectively collect the raised dust, and during the switching process, the dust separation cloth that does not absorb dust is cleaned under the action of the wind force. Therefore, the dust suction effect is ensured after switching, and during this process, the wind force is combined with the feeding component to make the dust material collected in the material storage pipe be conveyed into the mixing tank again. Therefore, the ratio of each raw material of the dry mortar in the mixing tank is ensured, making the quality of the dry mortar better after production. Furthermore, through the set dust reduction component and feeding component, during the dust reduction process, the raised dust is absorbed and collected by the dust reduction component, and then the collected dust raw material is conveyed into the mixing tank for mixing again through the action of the feeding component. Therefore, the problem in the prior art that the ratio of raw materials is affected by the absorbed dust and finally the quality of the dry mortar is affected is solved. Description of the Drawings

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 - 10 , the present invention provides a technical solution: a dust reduction device for dry mortar production, including a fixed frame 1, a dust reduction component 4 and a feeding component 8. A mixing tank 2 is fixedly connected to the fixed frame 1, and a storage barrel 3 is installed at the bottom end of the mixing tank 2. The dust reduction component 4 includes a dust suction ring 5 fixed at the top position of the mixing tank 2. A number of groups of dust suction holes 6 are provided on the dust suction ring 5, and a docking pipe 7 extending to the outside of the mixing tank 2 is communicated with the dust suction ring 5. The dust reduction component 4 absorbs the dust generated inside the mixing tank 2 through the negative pressure generated inside the dust suction ring 5. The feeding component 8 is communicated with the mixing tank 2, and the feeding component 8 is arranged in cooperation with the dust reduction component 4, and the feeding component 8 is used to re-transport the dust absorbed in the dust reduction component 4 into the mixing tank 2, so as to ensure the material ratio inside the mixing tank 2.

[0034] In this solution, during the process of material transportation, by starting the dust reduction component 4, the negative pressure is generated inside the dust suction ring 5 due to the start of the dust reduction component 4. The raised dust is absorbed and centrally collected through the action of the negative pressure, and then the collected dust is transported into the mixing tank 2 again through the action of the feeding component 8, thereby avoiding affecting the raw material ratio of the dry mortar.

[0035] The dust-removing assembly 4 includes a connecting pipe 9 communicated with the docking pipe 7. One end of the connecting pipe 9 is communicated with a collecting pipe 10. A switching member 11 is installed in the collecting pipe 10. Two groups of communicating pipes 12 are communicated with the collecting pipe 10. The ends of the two groups of communicating pipes 12 are respectively communicated with a first dust suction pipe 13 and a second dust suction pipe 14. A dust separation cloth 15 is installed in the first dust suction pipe 13 and the second dust suction pipe 14. The ends of the first dust suction pipe 13 and the second dust suction pipe 14 are respectively communicated with a first air suction pipe 16 and a second air suction pipe 17. The ends of the first air suction pipe 16 and the second air suction pipe 17 are connected with an air suction member 18. The air suction member 18 includes a fixed seat 19 fixedly connected with the fixed frame 1. A motor 20 is fixedly connected to the fixed seat 19. The output end of the motor 20 is fixedly connected with a coupling 21. One end of the coupling 21 is fixedly connected with a driving shaft 22. A wind wheel 23 is fixedly connected to the driving shaft 22. A wind hood 24 is sleeved on the outer side of the wind wheel 23. One end of the wind hood 24 is communicated with a first air extraction pipe 25 communicated with the first air suction pipe 16, and the other end of the wind hood 24 is communicated with a second air extraction pipe 26 communicated with the second air suction pipe 17. The switching member 11 includes a sealing inclined block 27 installed inside the collecting pipe 10. A rotating shaft 28 rotatably connected with the collecting pipe 10 is fixedly connected to the sealing inclined block 27. A torsion spring 29 fixedly connected with the collecting pipe 10 is fixedly connected to the rotating shaft 28. The end of the rotating shaft 28 is connected with a transmission member 30 connected with the driving shaft 22. The transmission member 30 includes an incomplete gear 31 fixedly connected to the rotating shaft 28. A spur gear 32 is meshed with the outside of the incomplete gear 31. A connecting shaft 33 fixedly connected with the driving shaft 22 is fixedly connected to the center of the spur gear 32. A support seat 34 fixedly connected with the fixed frame 1 is rotatably connected to the outer side of the connecting shaft 33.

[0036] In this solution, during the dust reduction process, by starting the motor 20, the motor 20 will drive the coupling 21 to rotate. Through the action of the coupling 21, the drive shaft 22 is driven to rotate, and then the wind wheel 23 is driven to rotate. Through the rotation of the wind wheel 23, suction is generated at one end of the wind cover 24, and wind force is generated at the other end of the wind cover 24. When the motor 20 rotates forward, suction is generated in the first air extraction pipe 25 connected to the first dust suction pipe 13, and wind force is generated in the second air extraction pipe 26. Since the first air extraction pipe 25 is connected to the first dust suction pipe 13 through the first air suction pipe 16, after suction is generated in the first air extraction pipe 25, suction is generated inside the first dust suction pipe 13. In this state, since the rotation of the drive shaft 22 will drive the connecting shaft 33 to rotate, the spur gear 32 is driven to rotate, and then the incomplete gear 31 is driven to rotate, and then the rotating shaft 28 is driven to rotate, and then the sealing inclined block 27 is driven to rotate. Through the rotation of the sealing inclined block 27, the communicating pipe 12 connecting the collecting pipe 10 and the first dust suction pipe 13 is communicated, and the other group of communicating pipes 12 is in a sealed state. It should be noted that: after the incomplete gear 31 disengages from the spur gear 32, at this time, through the action of the torsion spring 29, the incomplete gear 31 is always in a state of just disengaging from the spur gear 32 and maintaining this state. Therefore, after the incomplete gear 31 disengages from the spur gear 32, the rotating shaft 28 stops rotating. At this time, the first dust suction pipe 13 is connected to the docking pipe 7 through the communicating pipe 12, the collecting pipe 10, and the connecting pipe 9. The docking pipe 7 is connected to the dust suction pipe. Therefore, when the motor 20 rotates forward, suction is generated inside the dust suction ring 5 to absorb all the dust into the first dust suction pipe 13. Through the action of the dust separation cloth 15, the dust is prevented from flowing out of the first dust suction pipe 13.

[0037] In this solution, after the first dust suction pipe 13 has absorbed dust for a period of time, the dust separation cloth 15 is covered with a lot of dust, which affects its ability to absorb dust. At this time, the motor 20 rotates in the reverse direction, and then the coupling 21 drives the drive shaft 22 to rotate in the reverse direction. Therefore, the wind wheel 23 rotates in the reverse direction. At this time, suction is generated inside the second air extraction pipe 26, and wind force is generated in the first air extraction pipe 25. At this time, since the drive shaft 22 rotates in the reverse direction, the spur gear 32 drives the incomplete gear 31 to rotate in the reverse direction, so the sealing inclined block 27 is driven to rotate in the reverse direction. It should be noted that: the rotation state of the incomplete gear 31 in this state is the same as the rotation state when the motor 20 rotates forward, that is, after the incomplete gear 31 disengages from the spur gear 32, the incomplete gear 31 stops rotating, and then the state of the sealing inclined block 27 is set. In this state, the second dust suction pipe 14, the communicating pipe 12, and the collecting pipe 10 are communicated. Therefore, when the motor 20 rotates in the reverse direction, all the dust is absorbed into the second dust suction pipe 14 through the action of suction.

[0038] In this solution, after the wind force is generated in the first exhaust duct 25, the wind force will be conveyed to the inside of the first dust suction pipe 13 through the first suction pipe 16. Through the action of the wind force, the dust separation cloth 15 in the first dust suction pipe 13 will be blown, causing the dust separation cloth 15 to vibrate, thereby shaking off the dust on the dust separation cloth 15. Furthermore, to avoid the situation in the next use, after the motor 20 rotates in reverse for a period of time, the dust separation cloth 15 in the second dust suction pipe 14 will also be covered with dust. At this time, the motor 20 is switched to rotate forward again. At this time, the first dust suction pipe 13 absorbs the dust, and through the action of the wind force, the dust separation cloth 15 inside the second dust suction pipe 14 is cleaned. By switching the forward and reverse rotations of the motor 20 back and forth, the first dust suction pipe 13 and the second dust suction pipe 14 absorb the dust back and forth, and the dust separation cloth 15 can be cleaned during the switching, thereby facilitating the continuous collection of dust for a long time.

[0039] The blanking assembly 8 includes two groups of discharge pipes 35. The two groups of discharge pipes 35 are respectively communicated with the first dust suction pipe 13 and the second dust suction pipe 14. The end of the discharge pipe 35 is communicated with a blanking pipe 36. The end of the blanking pipe 36 is communicated with a storage pipe 37. One end of the storage pipe 37 is communicated with a discharge pipe 38 extending into the mixing tank 2. A baffle 39 fixedly connected to the mixing tank 2 is installed at the end of the discharge pipe 38. A one-way seal 40 is installed inside the discharge pipe 38. The one-way seal 40 includes a fixing piece 41 fixed inside the discharge pipe 38. A blanking hole 42 is formed in the fixing piece 41. A tension spring 43 is fixedly connected to the fixing piece 41. One end of the tension spring 43 is fixedly connected to a sealing block 44. The outer side of the sealing block 44 is movably connected to a sealing ring 45 fixedly connected to the discharge pipe 38.

[0040] In this solution, during the process of the first dust suction pipe 13 and the second dust suction pipe 14 absorbing dust, when the dust enters the inside of the first dust suction pipe 13 or the second dust suction pipe 14, the dust will enter the inside of the storage pipe 37 through the discharge pipe 35 and the feeding pipe 36 under the action of gravity. When the first dust suction pipe 13 is in the dust suction state, the dust inside the first dust suction pipe 13 will enter the inside of the storage pipe 37. At this time, wind force will be generated inside the second dust suction pipe 14. Since the second dust suction pipe 14, the connecting pipe 12 and the collecting pipe 10 are not connected at this time, the wind force will be transported to the inside of the storage pipe 37 through the feeding pipe 36 and the discharge pipe 35, and the material will be blown into the discharge pipe 38 under the action of the wind force. At this time, the sealing block 44 moves under the action of pressure, so the dust will be blown out through the gap between the sealing block 44 and the sealing ring 45 into the stirring tank 2. Due to the baffle 39 arranged at the end of the discharge pipe 38, the blown dust material will not be lifted up in a large amount again, so that the collected dust will not enter the stirring tank 2 again. When the second dust suction pipe 14 is in the dust suction state, the feeding method of the other set of storage pipes 37 is the same as the above feeding method, and will not be elaborated here.

[0041] In this solution, during the dust suction process, due to the sealing block 44 and the sealing block 44 arranged in the discharge pipe 38, and the sealing block 44 arranged in this solution can only move unidirectionally, so during the dust suction process, the discharge pipe 38 is in a sealed state, and thus no negative pressure will be generated inside the storage pipe 37, which ensures that enough negative pressure is generated in the dust suction ring 5 to facilitate the absorption of the dust lifted during the transportation process.

[0042] In this solution, the cross-sections of the fixing piece 41 and the sealing ring 45 are both conical, which is beneficial to transporting the material inside the storage pipe 37 into the stirring tank 2. The storage pipe 37 is inclined, which is convenient for the material to accumulate at the bottom of the storage pipe 37 under the action of gravity and is also convenient for transporting the material into the stirring tank 2.

[0043] A method for using a dust reduction device for dry mortar production includes the following steps:

[0044] S1. Dust suction: The motor rotates forward, generating negative pressure inside the first dust suction pipe, and the dust enters the first dust suction pipe under the action of the negative pressure.

[0045] S2. Switching: The motor rotates in reverse. At this time, negative pressure is generated inside the second dust suction pipe, and the dust enters the second dust suction pipe under the action of the negative pressure.

[0046] S3. Cleaning: In steps S1 and S2, when negative pressure is generated in the first dust suction pipe, wind force is generated inside the second dust suction pipe, and the dust-proof cloth inside the second dust suction pipe is cleaned under the action of the wind force, and vice versa.

[0047] S4. Material discharging: In steps S1 and S2, after the dust is absorbed, it will finally fall into the interior of the storage pipe, and the dust raw material is transported into the mixing tank again by the action of wind force.

[0048] Working principle: During the dust removal process, by starting the motor 20, the motor 20 will drive the coupling 21 to rotate. Through the action of the coupling 21, the drive shaft 22 is driven to rotate, and then the wind wheel 23 is driven to rotate. By the rotation of the wind wheel 23, suction is generated at one end of the wind hood 24, and wind force is generated at the other end of the wind hood 24. When the motor 20 rotates forward, suction is generated in the first extraction pipe 25 connected to the first dust suction pipe 13, and wind force is generated in the second extraction pipe 26. Since the first extraction pipe 25 is communicated with the first dust suction pipe 13 through the first suction pipe 16, after suction is generated in the first extraction pipe 25, suction is generated inside the first dust suction pipe 13. In this state, since the rotation of the drive shaft 22 will drive the connecting shaft 33 to rotate, the spur gear 32 is driven to rotate, and then the incomplete gear 31 is driven to rotate, and then the rotating shaft 28 is driven to rotate, and then the sealing inclined block 27 is driven to rotate. By the rotation of the sealing inclined block 27, the communicating pipe 12 connecting the collecting pipe 10 and the first dust suction pipe 13 is communicated, and the other group of communicating pipes 12 is in a sealed state. It should be noted that after the incomplete gear 31 is disengaged from the spur gear 32, at this time, through the action of the torsion spring 29, the incomplete gear 31 is always in a state of just being disengaged from the spur gear 32 and maintaining this state. Therefore, after the incomplete gear 31 is disengaged from the spur gear 32, the rotating shaft 28 stops rotating. At this time, the first dust suction pipe 13 is communicated with the docking pipe 7 through the communicating pipe 12, the collecting pipe 10 and the connecting pipe 9, and the docking pipe 7 is communicated with the dust suction pipe. Therefore, when the motor 20 rotates forward, suction is generated inside the dust suction ring 5 to absorb all the dust into the first dust suction pipe 13. Through the action of the dust separation cloth 15, the dust is prevented from flowing out of the first dust suction pipe 13. In this state, the dust will, due to the action of gravity, pass through the discharge pipe 35 and the blanking pipe 36 into the interior of the storage pipe 37.

[0049] In this solution, after the first dust suction pipe 13 has absorbed for a period of time, the dust-proof cloth 15 is covered with a lot of dust, which affects its ability to absorb dust. At this time, the motor 20 reverses, and the coupling 21 drives the drive shaft 22 to reverse, thereby causing the wind wheel 23 to reverse. At this time, suction is generated inside the second exhaust pipe 26, and wind is generated in the first exhaust pipe 25. At this time, due to the reversal of the drive shaft 22, the spur gear 32 drives the incomplete gear 31 to reverse, thereby driving the sealing bevel block 27 to reverse. It is worth noting that the rotation state of the incomplete gear 31 in this state is consistent with the rotation state of the motor 20 when it rotates forward. After the incomplete gear 31 is disengaged from the spur gear 32, the incomplete gear 31 stops rotating and then moves to the state of the sealing bevel block 27. In this state, the second dust suction pipe 14 is connected to the connecting pipe 12 and the collecting pipe 10, and then when the motor 20 reverses, the dust is completely sucked out by the suction. The dust particles are then sucked into the second dust suction pipe 14, and after wind is generated in the first exhaust pipe 25, the wind will be transported to the first dust suction pipe 13 through the first suction pipe 16, and the dust-proof cloth 15 in the first dust suction pipe 13 will be blown by the wind, so that the dust-proof cloth 15 will shake, and then the dust on the dust-proof cloth 15 will be shaken off, so as to avoid the next use. When wind is generated inside the first dust suction pipe 13, the wind will be transported to the inside of the storage pipe 37 through the feeding pipe 36 and the discharging pipe 35, and the material will be blown into the discharge pipe 38 by the wind. At this time, the sealing block 44 is moved by the pressure, so the dust will be blown into the mixing tank 2 through the gap between the sealing block 44 and the sealing ring 45. Due to the baffle 39 provided at the end of the discharge pipe 38, the blown dust material will not be raised in large quantities again, so that the collected dust will enter the mixing tank 2 again.

[0050] After the motor 20 reverses for a period of time, the dust-proof cloth 15 in the second dust suction pipe 14 will also be covered with dust. At this time, the motor 20 is switched to forward rotation again. At this time, the first dust suction pipe 13 absorbs the dust, and the dust-proof cloth 15 inside the second dust suction pipe 14 is cleaned by the action of wind. At this time, wind is generated inside the second dust suction pipe 14, and the wind enters another group of storage pipes 37 through another group of discharge pipes 35 and feed pipes 36. At this time, the storage pipe 37 once again transports the dust raw materials to the mixing tank 2. The transportation process is consistent with the above process, which will not be elaborated here. Therefore, by switching back and forth between forward and reverse rotation of the motor 20, the first dust suction pipe 13 and the second dust suction pipe 14 absorb the dust back and forth, and the dust-proof cloth 15 can be cleaned during switching, so as to facilitate long-term uninterrupted collection of dust. The collected dust can be transported to the mixing tank 2 again through the forward and reverse rotation of the motor 20, thereby improving the accuracy of the raw material ratio, reducing the error in the production of dry mortar, and improving the quality.
