Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a dust removal device for dry-mix mortar production. Background Art

[0002] Environmentally friendly mortar is a new type of environmentally friendly and energy-saving mortar material used for painting the interior and exterior walls of buildings. It has the characteristics of energy saving and waste utilization, thermal insulation, fire prevention and frost resistance, aging resistance and low price, and has a wide market demand. Dry-mixed mortar is usually called hydraulic cement mixed mortar. It refers to a granular or powdered material that is physically mixed in a certain proportion of dried and screened aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers). It is transported to the construction site in bags or bulk and can be used directly after adding water and mixing. However, a large amount of cement dust will be generated in the production process of dry-mixed mortar. Some of the cement dust will cause great pollution to the production environment of the factory, and will also cause great harm to the workers' health.

[0003] In the prior art, Chinese utility model disclosure specification CN210233502U discloses a dust removal device for a dry-mix mortar production line. A dust removal device for dry-mix mortar production is designed. The principle of the device is to use a blower to extract the dust inside the mixing tank and transport it to the inside of a dust treatment box. Water is provided inside the dust treatment box. The dust in the air is sprayed toward the water, and the water is used to absorb the dust in the air to achieve the purpose of dust reduction.

[0004] However, when the existing device is in use, dust is transported to the inside of the dust treatment box through a pipe, so that the internal air flows. There will also be a part floating inside the dust treatment box that has not merged with the water. The interior of the dust treatment box is a closed design. Continuously transporting air inside will cause the internal air pressure to be too high, so that it will be discharged from the gap inside the dust treatment box. In the process of discharge, the floating dust inside will be taken out, so the dust treatment is not perfect. Therefore, in response to the above-mentioned problems, a dust treatment device with more perfect dust treatment is designed. Utility Model Content

[0029] Dry-mixed mortar is generally made of cement, sand, fly ash, slag and admixtures with special properties. It is a granular or powdered mixture. Dry-mixed mortar has the advantages of stable quality, high efficacy, excellent quality, complete variety and easy use. During the production process of dry-mixed mortar, the raw materials need to be fed into a mixing tank for mixing. During the process of feeding the raw materials, the dust in the raw materials will be raised and float out through the feed port, seriously polluting the air.

[0030] In the related art, the dust inside the mixing tank is discharged into the treatment box so that it contacts the water surface and absorbs the dust in the air. However, when in use, the dust is transported to the inside of the dust treatment box through a pipe, causing the internal air to flow. There will also be a part floating inside the dust treatment box that has not merged with the water. The interior of the dust treatment box is a closed design. Continuously transporting air to the inside will cause the internal air pressure to be too high, so that it will be discharged from the gap inside the dust treatment box. In the process of discharge, the floating dust inside will be brought out, so the dust treatment is not perfect.

[0031] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a dry-mixed mortar production dust removal device. When the dry-mixed mortar is stirred by rotating inside the mixing tank 11, a large amount of dust will be generated. At the same time, the dust is transported to the inside of the dust treatment box 13 through the dust discharge pipe 14, and sprayed out from the inside of the jet disk 21. Because the jet disk 21 sinks in the water, bubbles will be sprayed out. At this time, the motor 25 is connected to the external power supply to drive the gear 2 26 to rotate, and at the same time, it is meshed with the gear 1 24 to drive the tube body 22 to rotate. At this time, the stirring rod 23 is driven to stir the water flow inside the dust treatment box 13, and the bubbles with dust are mixed with the water flow evenly, so that it can be better mixed with water to absorb the dust inside, and the excess air can be discharged from the top of the dust treatment box 13.

[0032] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figure 1-Figure 3The embodiment of the present application provides a dry-mixed mortar production dust removal device, comprising: a mixing tank 11, the outer wall of the mixing tank 11 is provided with a placement plate 12; the bottom of a dust treatment box 13 is inserted into the placement plate 12 and is fixedly connected to the placement plate 12; an ash discharge pipe 14 is arranged on the outer wall of the mixing tank 11, and the other end is inserted into the interior of the dust treatment box 13; a rotating component 2 is arranged inside the dust treatment box 13, and the rotating component 2 includes: an air jet disc 21 is arranged at the bottom of the ash discharge pipe 14; a tube body 22 is sleeved on the outer wall of the ash discharge pipe 14, and the top is rotatably connected to the inner wall of the dust treatment box 13; a stirring rod 23 is arranged on the outer wall of the tube body 22; a gear 1 24 is arranged on the outer wall of the tube body 22; a motor 25 is arranged at the top of the dust treatment box 13, and the output shaft is inserted into the interior of the dust treatment box 13; a gear 26 is arranged on the output shaft of the gear 2 26 and meshes with the gear 1 24.

[0034] Specifically, a fan is provided on the inner side wall of the top of the mixing tank 11 to discharge the dust inside into the dust discharge pipe 14. The fan belongs to the prior art and is not shown in the figure. The stirring rod 23 is welded to the outer side wall of the tube body 22, and the gear 1 24 and the gear 2 26 are connected to the tube body 22 and the motor 25 by welding.

[0035] When in use, the raw materials are placed into the mixing tank 11, and the mixing tank 11 is started to mix the raw materials inside to form a dry mixed mortar. A large amount of dust will be generated during the mixing process. At this time, the internal dust is discharged into the dust discharge pipe 14 through the fan. The dust is transported to the dust treatment box 13 and sprayed out from the inside of the jet disk 21. Because the jet disk 21 sinks in the water, bubbles will be sprayed out. At this time, the motor 25 is connected to the external power supply to drive the gear 2 26 to rotate, and at the same time engages with the gear 1 24 to drive the tube body 22 to rotate. At this time, the stirring rod 23 is driven to stir the water flow inside the dust treatment box 13, and the bubbles with dust are mixed with the water flow evenly, so that it can be better mixed with water to absorb the internal dust. Excess air can be discharged from the top of the dust treatment box 13.

[0036] In some embodiments, the bottom of the dust treatment box 13 is designed to be conical.

[0037] When in use, the conical design allows the dust to settle and collect at the bottom of the dust treatment box 13. When it needs to be discharged, the bottom cover can be opened and the water flow will bring the dirt out to complete the cleaning.

[0038] In some embodiments, the cross section of the stirring rod 23 is designed to be diamond-shaped.

[0039] When in use, the diamond-shaped design with sharp corners on both sides is more conducive to breaking the bubbles and mixing them with the water flow.

[0040] In some embodiments, all the air nozzles on the air jet disc 21 are arranged at the bottom.

[0041] When in use, the bubbles containing dust can be allowed to stay in the water flow for a longer time.

[0042] In some embodiments, the rotating assembly 2 further includes: a grid disk 27 disposed inside the dust processing box 13 .

[0043] Specifically, the grid plate 27 and the dust treatment box 13 are fixed by welding.

[0044] When in use, the grid plate 27 can slow down the stirring flow of water at the bottom of the dust treatment box 13 by the stirring rod 23, which can facilitate the precipitation of dust at the bottom.

[0045] In some embodiments, the rotating assembly 2 further includes: dustproof cotton 28 disposed on the top outlet of the dust treatment box 13; a cover 29 is sleeved on the top outlet of the dust treatment box 13 and threadedly connected thereto.

[0046] When in use, the excess air inside the dust treatment box 13 can be discharged from the top, and the dustproof cotton 28 can further filter it when it is discharged. After using it for a period of time, the cover 29 can be turned to replace the dustproof cotton 28.

[0047] In some embodiments, a water tank 31 is disposed on the top of the placement plate 12 , and a water pipe 32 is disposed between the water tank 31 and the dust treatment box 13 , and the water tank 31 and the dust treatment box 13 are connected to each other.

[0048] During use, when the sludge at the bottom of the dust treatment box 13 is discharged, the water inside the dust treatment box 13 becomes less. At this time, the water inside the water tank 31 will flow into the dust treatment box 13 through the water pipe 32 to balance the water amount inside the dust treatment box 13.

[0049] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0050] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
