Description

Technical Field

[0001] The utility model belongs to the technical field of heavy calcium carbonate processing, and in particular to a raw material conveying device for heavy calcium carbonate processing. Background Technique

[0002] Heavy calcium carbonate, abbreviated as heavy calcium, is ground from natural carbonate minerals such as calcite, marble, and limestone. During the production process, the original stone is crushed into powder and moved to the next processing step through a conveying device. Since the original stone powder will be in a powdery state after grinding, when the original stone powder is put on the conveyor belt for transportation, there will be a large amount of dust flying, so that the dust in the powder will float in the air. Moreover, during the transportation process of the conveyor belt, there will also be a dust flying phenomenon, resulting in the dust floating in the air being easily inhaled by the staff. This not only easily pollutes the working environment, but also easily affects the physical and mental health of the staff.

[0003] For example, in the existing ore conveying device for heavy calcium carbonate processing with the Chinese publication number: CN217946462U, it: "includes a conveyor belt, an installation block is installed inside the conveyor belt, a top block is installed inside the installation block, the installation block is slidably connected to the top block, and an extension block is formed inside the installation block extending towards the position of the top block. The extension block is slidably connected inside the top block."

[0004] It can be seen that the cited patent document has the problem of being difficult to handle dust flying. Content of the Utility Model

[0005] The purpose of the utility model is to provide a raw material conveying device for heavy calcium carbonate processing to solve the problems raised in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A raw material conveying device for heavy calcium carbonate processing, including a dust-proof box. Inside the dust-proof box, there is a conveyor belt for conveying heavy calcium carbonate raw materials.

Above the conveyor belt inside the dust-proof box, there is a dust suction hood. The top surface of the dust suction hood is communicated with a dust suction pipe passing through the dust-proof box. The free end of the dust suction pipe is provided with a treatment box. On one side surface of the treatment box, there is a first dust suction pump, and the first dust suction pump is communicated with the dust suction pipe. The first dust suction pump is communicated with the treatment box through a first dust discharge pipe. Inside the cavity of the treatment box, there is a dust reduction structure for treating dust.

[0007] Preferably, the dust reduction structure includes a shunt plate, a water pipe, and a plurality of spray heads. The shunt plate is fixedly arranged on the inner bottom surface of the treatment box through a bracket.

[0008] Preferably, several of the spray heads are equidistantly installed on the bottom surface of the flow dividing plate, and the water pipe communicates with the top surface of the flow dividing plate.

[0009] Preferably, the free end of the water pipe penetrates to one side of the treatment box and is externally connected to a water supply device, and a second dust suction pump is installed on one side surface of the treatment box.

[0010] Preferably, the second dust suction pump communicates with the treatment box through a second dust discharge pipe, the second dust suction pump is connected with a connecting pipe, and the free end of the connecting pipe penetrates into the inner cavity of the dust-proof box.

However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0024] Unless otherwise defined, the up, down, left, right, front, back, inside and outside directions involved in this article are based on the up, down, left, right, front, back, inside and outside directions in the figures shown in the present utility model, and are hereby explained together.

[0025] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., subject to actual needs.

[0026] Such as Figures 1 to 4A raw material conveying device for heavy calcium carbonate processing shown in the figure includes a dust-proof box 1. The dust-proof box 1 is installed between two devices for producing heavy calcium carbonate. Inside the dust-proof box 1, there is a conveyor belt 2 for conveying heavy calcium carbonate raw materials. On both sides of the dust-proof box 1, there are fixedly installed protective covers 3 for abutting against the devices for processing heavy calcium carbonate. Inside the cavities of the two protective covers 3, there are guide plates 4 for conveying heavy calcium carbonate raw materials. The two guide plates 4 are respectively inclined from top to bottom. The two protective covers 3 respectively abut against the two devices for producing heavy calcium carbonate, so that after the heavy calcium carbonate raw materials pass through the previous processing procedure, they will directly enter the cavities of the protective covers 3 and move along the guide plates 4 to the conveyor belt 2 for movement. The conveyor belt 2 will move the heavy calcium carbonate raw materials to another guide plate 4 and move to the next processing procedure through another guide plate 4. During the movement, the heavy calcium carbonate raw materials are always inside the dust-proof box 1 and the protective covers 3, so that the dust emitted by the heavy calcium carbonate raw materials is always inside the dust-proof box 1 and the protective covers 3, preventing the dust from diffusing in the air.

[0027] Above the conveyor belt 2 and inside the cavity of the dust-proof box 1, there is a dust suction hood 5. The top surface of the dust suction hood 5 is connected to a dust suction pipe 6 that penetrates the dust-proof box 1. The free end of the dust suction pipe 6 is provided with a treatment box 7. On one side surface of the treatment box 7, there is a first dust suction pump 8 installed. The first dust suction pump 8 is connected to the dust suction pipe 6. The first dust suction pump 8 is connected to the treatment box 7 through a first dust discharge pipe 9. When the dust of the heavy calcium carbonate raw materials diffuses inside the dust-proof box 1, the first dust suction pump 8 is turned on, so that the first dust suction pump 8 extracts the dust through the dust suction pipe 6 and the dust suction hood 5 and discharges the dust into the treatment box 7 through the first dust discharge pipe 9, thereby treating the dust of the heavy calcium carbonate raw materials, preventing the dust of the heavy calcium carbonate raw materials from floating in the air during transportation, and reducing the impact on the working environment and the physical and mental health of the staff.

[0028] Inside the cavity of the treatment box 7, there is a dust reduction structure for treating dust. The dust reduction structure includes a diversion plate 10, a water pipe 11, and several spray heads 12. The diversion plate 10 is fixedly arranged on the inner bottom surface of the treatment box 7 through a bracket. The several spray heads 12 are equidistantly installed on the bottom surface of the diversion plate 10. The water pipe 11 is connected to the top surface of the diversion plate 10. The free end of the water pipe 11 penetrates to one side of the treatment box 7 and is externally connected to a water supply device. After the dust enters the treatment box 7, the externally connected water resources are conveyed to the diversion plate 10 through the water pipe 11, so that the diversion plate 10 disperses the water to multiple spray heads 12 and sprays out from the spray heads 12, enabling the dust and water to be mixed, allowing the dust to precipitate with the water, and discharging the water mixed with the dust out of the treatment box 7 through the inclined plate on the inner bottom surface and the leak port on one side surface of the treatment box 7, so that the water can be filtered and recycled, and the dust can also be treated, preventing the dust from still diffusing in the air when the treatment box 7 is opened.

[0029] On the inner sidewall of the dust-proof box 1 and symmetrically and rotatably connected below the conveyor belt 2 are drum brushes 17 for cleaning the conveyor belt 2. On one side of the dust-proof box 1, drive motors 16 are symmetrically installed. The output ends of the two drive motors 16 respectively penetrate through the dust-proof box 1 and are connected to one end of the drum brush 17. When the heavy calcium carbonate raw material is transported by the conveyor belt 2, the drive motors 16 are turned on, and the drive motors 16 drive the drum brushes 17 to rotate, so that the drum brushes 17 can clean the heavy calcium carbonate raw material remaining on the surface of the conveyor belt 2.

[0030] On one side of the processing box 7, a second dust suction pump 14 is installed. The second dust suction pump 14 is communicated with the processing box 7 through a second dust discharge pipe 15. The second dust suction pump 14 is communicated with a connecting pipe 13. The free end of the connecting pipe 13 penetrates into the inner cavity of the dust-proof box 1, and one end of the connecting pipe 13 in the dust-proof box 1 is located below the conveyor belt 2. When the drum brush 17 cleans the conveyor belt 2, the second dust suction pump 14 is turned on, and the second dust suction pump 14 absorbs the dust generated when the drum brush 17 cleans the conveyor belt 2 through the connecting pipe 13 and the second dust discharge pipe 15, and moves it into the processing box 7 for processing.

[0031] Working principle:

[0032] For this raw material conveying device for heavy calcium carbonate processing, the two protective covers 3 are respectively abutted against the two devices for processing heavy calcium carbonate, so that the heavy calcium carbonate raw material discharged in the previous processing step will directly move to the conveyor belt 2 through the guiding plate 4, and can be conveyed through the conveyor belt 2, enabling the heavy calcium carbonate raw material to move along another guiding plate 4 to the next processing step for production. The dust-proof box 1 and the two protective covers 3 can limit the dust and prevent the dust from diffusing in the air. At this time, the first dust suction pump 8 is turned on, and the first dust suction pump 8 sucks the dust in the dust-proof box 1 through the dust suction pipe 6 and the dust suction cover 5, and discharges the dust through the first dust discharge pipe 9 into the processing box 7. At the same time, the dust is treated through the dust reduction structure, mixing the dust with water and discharging the water from the processing box 7, so as to treat the dust generated by the heavy calcium carbonate raw material, prevent the dust from the heavy calcium carbonate raw material from floating in the air during transportation, and reduce the impact on the working environment and the physical and mental health of the staff.
