Description

Technical Field

[0001] The present invention relates to the technical field of dry-mix mortar production, and in particular to a dust reduction device and method for dry-mix mortar production. Background Art

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

[0003] At present, in the process of dry-mix mortar production, each group of materials needs to be put into the mixing tank according to a suitable ratio for mixing, and then the dry-mix mortar required in the construction industry is obtained. In the mixing process, the raw materials are transported to the mixing tank through the action of the feeding piece. When the materials are transported to the mixing tank, since the raw materials are in powder or granular form, a large amount of raw material dust will be raised during the transportation process. The dust entering the production workshop will affect the environment of the workshop and easily affect the health of the staff. Therefore, dust reduction operations are required during the feeding process. In the prior art, dust reduction generally uses a vacuum cleaner to absorb the dust to achieve the effect of dust reduction. However, after vacuuming, the collected dust will not be transported to the inside of the mixing tank, thus causing an imbalance in the proportion of the raw materials, which may affect the quality of the dry-mix mortar.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 10The present invention provides a technical solution: a dust reduction device for dry mortar production, comprising a fixed frame 1, a dust reduction component 4 and a feeding component 8, the fixed frame 1 is fixedly connected with a mixing tank 2, a discharging barrel 3 is installed at the bottom end of the mixing tank 2, the dust reduction component 4 comprises a dust suction ring 5 fixed at the top position of the mixing tank 2, a plurality of dust suction holes 6 are opened on the dust suction ring 5, and the dust suction ring 5 is connected with a butt pipe 7 extending to the outside of the mixing tank 2, 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 connected with the mixing tank 2, and the feeding component 8 is matched with the dust reduction component 4, and the feeding component 8 is used to transport the dust absorbed in the dust reduction component 4 back into the mixing tank 2, thereby ensuring the material ratio inside the mixing tank 2.

[0020] In this solution, during the material transportation process, the dust reduction component 4 is started, so that a negative pressure is generated inside the dust suction ring 5, and the raised dust is absorbed and collected by the negative pressure, and then the collected dust is transported to the mixing tank 2 again by the action of the discharge component 8, thereby avoiding affecting the raw material ratio of the dry mortar.

[0021] The dust reduction assembly 4 includes a connecting pipe 9 connected to the butt pipe 7, one end of the connecting pipe 9 is connected to a collecting pipe 10, a switching member 11 is installed in the collecting pipe 10, and two groups of connecting pipes 12 are connected to the collecting pipe 10, and the ends of the two groups of connecting pipes 12 are respectively connected to a first dust suction pipe 13 and a second dust suction pipe 14, dust-proof cloths 15 are 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 connected to a first air suction pipe 16 and a second air suction pipe 17, and the ends of the first air suction pipe 16 and the second air suction pipe 17 are connected to an air suction member 18, and the air suction member 18 includes a fixing seat 19 fixedly connected to the fixing frame 1, a motor 20 is fixedly connected to the fixing seat 19, an output end of the motor 20 is fixedly connected to a coupling 21, one end of the coupling 21 is fixedly connected to a drive shaft 22, a wind wheel 23 is fixedly connected to the drive shaft 22, and the wind wheel 2 The outer side of the hood 24 is sleeved with a hood 24, one end of the hood 24 is connected to a first exhaust pipe 25 connected to the first suction pipe 16, and the other end of the hood 24 is connected to a second exhaust pipe 26 connected to the second suction pipe 17, the switching member 11 includes a sealing bevel 27 installed inside the manifold 10, a rotating shaft 28 rotatably connected to the manifold 10 is fixedly connected to the sealing bevel 27, a torsion spring 29 fixedly connected to the manifold 10 is fixedly connected to the rotating shaft 28, and a transmission member 30 connected to the drive shaft 22 is connected to the end of the rotating shaft 28, the transmission member 30 includes an incomplete gear 31 fixedly connected to the rotating shaft 28, a spur gear 32 is meshed on the outer side of the incomplete gear 31, a connecting shaft 33 fixedly connected to the drive shaft 22 is fixedly connected to the axis center of the spur gear 32, and a supporting seat 34 fixedly connected to the fixing frame 1 is rotatably connected to the outer side of the connecting shaft 33.

[0022] In the present solution, during the dust reduction process, by starting the motor 20, the motor 20 will drive the coupling 21 to rotate, and the driving shaft 22 will be driven to rotate through the action of the coupling 21, thereby driving the wind wheel 23 to rotate. The rotation of the wind wheel 23 generates suction 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 force is generated in the first exhaust pipe 25 connected to the first dust suction pipe 13, and wind force is generated in the second exhaust pipe 26. Since the first exhaust pipe 25 is connected to the first dust suction pipe 13 through the first suction pipe 16, after the first exhaust pipe 25 generates suction force, suction force is generated inside the first dust suction pipe 13. In this state, the rotation of the driving shaft 22 will drive the connecting shaft 33 to rotate, thereby driving the flat gear 32 to rotate, thereby driving the incomplete gear 31 to rotate, and then driving the rotating shaft 28 to rotate, thereby The sealing bevel 27 is driven to rotate, and the rotation of the sealing bevel 27 makes the collecting pipe 10 communicate with the connecting pipe 12 connected to the first dust suction pipe 13, while the connecting pipe 12 of the other group is in a sealed state. It is worth noting that: after the incomplete gear 31 is disengaged from the flat gear 32, the torsion spring 29 makes the incomplete gear 31 always in a state of just disengagement from the flat gear 32, and maintains this state. Therefore, after the incomplete gear 31 is disengaged from the flat gear 32, the rotating shaft 28 stops rotating. At this time, the first dust suction pipe 13 is connected to the connecting pipe 7 through the connecting pipe 12, the collecting pipe 10 and the connecting pipe 9, and the connecting 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, and the dust is prevented from flowing out of the first dust suction pipe 13 by the dust-proof cloth 15.

[0023] 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, thereby causing the coupling 21 to drive 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 flat 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 flat 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, all the dust is absorbed into the second dust suction pipe 14 by the action of suction.

[0024] In this solution, after wind is generated in the first exhaust pipe 25, the wind will be transported to the inside of the first dust suction pipe 13 through the first suction pipe 16. The wind will blow the dust-proof cloth 15 in the first dust suction pipe 13, causing the dust-proof cloth 15 to shake, thereby shaking off the dust on the dust-proof cloth 15 to avoid the next use. 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 wind and dust, and the dust-proof cloth 15 inside the second dust suction pipe 14 is cleaned by the action of wind. By switching the motor 20 back and forth between forward and reverse rotation, 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, thereby facilitating long-term uninterrupted dust collection.

[0025] The discharge assembly 8 includes two groups of discharge pipes 35, and the two groups of discharge pipes 35 are respectively connected to the first dust suction pipe 13 and the second dust suction pipe 14, and the end of the discharge pipe 35 is connected to the discharge pipe 36, and the end of the discharge pipe 36 is connected to the storage pipe 37, and one end of the storage pipe 37 is connected to a discharge pipe 38 extending to the inside of the mixing tank 2, and a baffle 39 fixedly connected to the mixing tank 2 is installed at the end of the discharge pipe 38, and a one-way seal 40 is installed inside the discharge pipe 38, and the one-way seal 40 includes a fixed plate 41 fixed to the inside of the discharge pipe 38, a discharge hole 42 is opened on the fixed plate 41, and a tension spring 43 is fixedly connected to the fixed plate 41, and one end of the tension spring 43 is fixedly connected to a sealing block 44, and the outer side surface of the sealing block 44 is movably connected to a sealing ring 45 fixedly connected to the discharge pipe 38.

[0026] 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 first dust suction pipe 13 or the second dust suction pipe 14, the dust will enter the storage pipe 37 through the discharge pipe 35 and the lower feed pipe 36 due to 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 storage pipe 37. At this time, wind will be generated inside the second dust suction pipe 14. At this time, since the second dust suction pipe 14 and the connecting pipe 12 are not connected to the collecting pipe 10, the wind will pass through the lower feed pipe 36 and the discharge pipe 35 is transported to the inside of the material storage pipe 37, and the material is blown into the discharge pipe 38 by the action of wind. At this time, the sealing block 44 is moved by the action of 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 set at the end of the discharge pipe 38, the blown dust material will not be raised again in large quantities, so that the collected dust will enter the mixing tank 2 again. When the second dust suction pipe 14 is in the dust suction state, the method of unloading materials in the other group of material storage pipes 37 is the same as the above-mentioned unloading method, which will not be elaborated here.

[0027] In this solution, during the vacuuming process, due to the sealing block 44 and the sealing block 44 set in the discharge pipe 38, and the sealing block 44 set in this solution can only move in one direction, the discharge pipe 38 is in a sealed state during the vacuuming process, and no negative pressure is generated inside the storage pipe 37, thereby ensuring that sufficient negative pressure is generated in the dust collection ring 5, which is convenient for absorbing the dust raised during the transportation process.

[0028] In this embodiment, the cross-sections of the fixing plate 41 and the sealing ring 45 are both conical, which is conducive to transporting the material inside the storage pipe 37 to the inside of the mixing tank 2. The storage pipe 37 is arranged at an angle, which makes it convenient for the material to accumulate at the bottom end of the storage pipe 37 through the action of gravity, and facilitates the transportation of the material to the inside of the mixing tank 2.

[0029] A method for using a dust suppression device for dry mortar production comprises the following steps: S1. Vacuuming: The motor rotates forward, so that negative pressure is generated inside the first vacuum pipe, and the dust enters the first vacuum pipe through the negative pressure; S2. Switching: The motor reverses, and negative pressure is generated inside the second dust suction pipe, causing the dust to enter the second dust suction pipe through the negative pressure. S3. Cleaning: In step S1 and step S2, when the first vacuum tube generates negative pressure, the second vacuum tube generates wind force inside, and the dust-proof cloth inside the second vacuum tube is cleaned by the wind force, and vice versa; S4. Unloading: In step S1 and step S2, the dust is absorbed and finally falls into the storage pipe. The dust raw material is transported to the mixing tank again by wind force.

[0030] Working principle: During the dust reduction process, by starting the motor 20, the motor 20 will drive the coupling 21 to rotate, and the driving shaft 22 will be driven to rotate through the action of the coupling 21, thereby driving the wind wheel 23 to rotate. The rotation of the wind wheel 23 generates suction 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 force is generated in the first exhaust pipe 25 connected to the first dust suction pipe 13, and wind force is generated in the second exhaust pipe 26. Since the first exhaust pipe 25 is connected to the first dust suction pipe 13 through the first suction pipe 16, after the first exhaust pipe 25 generates suction force, suction force is generated inside the first dust suction pipe 13. In this state, the rotation of the driving shaft 22 will drive the connecting shaft 33 to rotate, thereby driving the flat gear 32 to rotate, thereby driving the incomplete gear 31 to rotate, thereby driving the rotating shaft 28 to rotate, thereby driving the sealing bevel block 27 to rotate, and through the rotation of the sealing bevel block 27 The movement makes the collecting pipe 10 connected to the connecting pipe 12 connected to the first dust suction pipe 13 connected, while the other group of connecting pipes 12 is in a sealed state. It is worth noting that: after the incomplete gear 31 is disengaged from the flat gear 32, the torsion spring 29 makes the incomplete gear 31 always in a state of just disengagement from the flat gear 32, and maintains this state. Therefore, after the incomplete gear 31 is disengaged from the flat gear 32, the rotating shaft 28 stops rotating. At this time, the first dust suction pipe 13 is connected to the connecting pipe 12, the collecting pipe 10 and the connecting pipe 9 through the connecting pipe 12 and the connecting pipe 9. The connecting pipe 7 is connected to the dust suction pipe. Therefore, when the motor 20 rotates forward, the dust suction ring 5 generates suction to absorb all the dust into the first dust suction pipe 13. The dust is prevented from flowing out of the first dust suction pipe 13 by the dust-proof cloth 15. In this state, the dust will enter the storage pipe 37 through the discharge pipe 35 and the feed pipe 36 due to the action of gravity.

[0031] 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. 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.
