Description

Technical Field

[0001] The present invention relates to the technical field of heavy calcium carbonate production and transportation, and particularly relates to a heavy calcium carbonate production and transportation rack. Background Art

[0002] Heavy calcium carbonate is made by crushing raw materials such as calcite, limestone, chalk or shells. During the production process of heavy calcium carbonate, it is necessary to first perform preliminary crushing on the heavy calcium carbonate raw materials to facilitate subsequent crushing of the raw materials. The raw materials after preliminary crushing need to be transported to a crusher by a conveying device for crushing.

[0003] Currently, when transporting the crushed raw materials, the crushed raw materials directly fall onto the conveying device after crushing and are then directly transported by the conveying device. During transportation, the crushed raw materials are directly exposed. During this period, a large amount of dust is easily attached to the crushed raw materials, and a large amount of dust will fly during falling and transportation. In the long run, the dust concentration in the production workshop will gradually increase, thus posing a risk of dust explosion, and the escaped dust is easily inhaled by workers, which is harmful to the health of workers.

Detailed implementation manners

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] Embodiment 1: A conveying rack for the production of heavy calcium carbonate. Please refer to Figures 1-4 , which includes a support frame 1. A conveying assembly 11 is installed on the support frame 1. Uniformly arranged baffle plates 12 are fixedly connected to the surface of the conveying part of the conveying assembly 11. A protective cover 13 is fixedly connected to the upper left side of the support frame 1. A vertical feeding cylinder 14 is welded to the protective cover 13. A spiral feeding paddle 15 is rotatably connected inside the feeding cylinder 14. A motor 16 is installed on the upper right side of the feeding cylinder 14 through a mounting frame. A worm 17 is rotatably connected to the top of the feeding cylinder 14 through a support block. The right side of the worm 17 is connected to the output shaft of the motor 16 through a coupling. The upper part of the spiral feeding paddle 15 passes through the feeding cylinder 14 and is connected with a worm gear 18. The worm gear 18 meshes with the worm 17. The upper left side of the feeding cylinder 14 is communicated with a feeding pipe 19.

[0033] In use, pour the preliminarily crushed heavy calcium carbonate raw material into the feeding pipe 19, and then start the motor 16. The output shaft of the motor 16 drives the worm 17 to rotate, thereby driving the worm wheel 18 and the spiral feeding paddle 15 to rotate, so that the spiral feeding paddle 15 conveys the preliminarily crushed heavy calcium carbonate raw material. Since the spiral feeding paddle 15 can slow down the falling speed of the crushed raw material when feeding the crushed raw material, thereby reducing the impact force when the crushed raw material falls. In this way, it can be avoided that when the crushed raw material is fed, dust will fly due to the large impact force during falling, and thus it can be avoided that dust escapes, preventing the dust density in the workshop for processing heavy calcium carbonate from being too high, resulting in the risk of dust explosion, and it can also avoid workers inhaling the escaped dust, ensuring the health of workers. When the crushed raw material falls onto the conveying component 11, the conveying component 11 conveys the crushed raw material into the pulverizer for processing into powder. When the conveying component 11 conveys the crushed raw material, it drives the baffle plate 12 to move, and the baffle plate 12 drives the raw material to move. In this way, the raw material can be separated, facilitating subsequent pulverization. After completion, just turn off the motor 16.

[0034] Example 2: On the basis of Example 1, please refer to Figures 1-3 and Figures 5-9 , and further includes a dust suction hood 2. The dust suction hood 2 is fixedly connected to the lower side of the feeding cylinder 14. The left side of the dust suction hood 2 is communicated with a dust suction pipe 21. An air pump 22 is fixedly connected to the outer wall of the protective cover 13 through a support seat. The air pump 22 is communicated with the dust suction pipe 21. The left side of the air pump 22 is communicated with a hose 23.

[0035] Place the collection box on the protective cover 13, and then insert the hose 23 into the collection box. When feeding the crushed raw material, start the air pump 22. The air pump 22 absorbs the dust generated during feeding through the dust suction pipe 21 and the dust suction hood 2, so that the dust enters the collection box for collection. In this way, it can further prevent dust from escaping, and can also collect the powder, avoiding waste of raw materials. After completion, turn off the air pump 22.

[0036] It further includes a cleaning brush 3. The cleaning brush 3 is rotatably connected to the left side of the support frame 1. Two torsion springs 31 are connected between the cleaning brush 3 and the support frame 1. A collection frame 32 is slidably placed at the lower part of the protective cover 13.

[0037] When the conveying component 11 conveys the crushed raw materials, since the cleaning brush 3 is in contact with the conveying component 11, the cleaning brush 3 can clean the dust attached to the surface of the conveying component 11, so that the cleaned dust falls into the collecting frame 32 for collection to avoid waste. In this way, the cleanliness of the conveying component 11 can be ensured to prevent dust from accumulating and then falling into the connection between the conveying component 11 and the support frame 1, thereby reducing wear. The torsion spring 31 can limit the cleaning brush 3 so that the cleaning brush 3 remains in contact with the conveying component 11.

[0038] It also includes six air cylinders 4, which are fixed to the left side of the bottom of the protective cover 13, and a lower pressure plate 41 is fixed between the tops of the piston rods in the six air cylinders 4. The piston rods of the six air cylinders 4 are all sleeved with linear springs 42, and a water tank 43 is fixed between the left side of the bottom of the protective cover 13 and the support frame 1. The bottoms of the six air cylinders 4 are all connected to water pumping pipes 44, and the six water pumping pipes 44 are all connected with one-way valves. The six water pumping pipes 44 all pass through the protective cover 13 and the water tank 43, and the ends of the six water pumping pipes 44 are all located in the water tank 43. The lower right sides of the six air cylinders 4 are connected with a first water pipe 45, and the first Six one-way valves are connected to the left side of the water pipe 45. The first water pipe 45 passes through the protective cover 13 and the support frame 1. The outer wall of the dust hood 2 is fixedly connected to a second water pipe 46, and the second water pipe 46 is communicated with the first water pipe 45. The outer wall of the dust hood 2 is fixedly connected to a third water pipe 49, and the third water pipe 49 is communicated with the first water pipe 45. The second water pipe 46 is evenly installed with atomizing nozzles 47 in a circumferential direction, and the bottom of the third water pipe 49 is evenly installed with atomizing nozzles 47 in a circumferential direction. The atomizing nozzles 47 on the third water pipe 49 are tilted. Two toggle rods 48 are fixedly connected to the left side of the baffle plate 12 on the conveying assembly 11.

[0039] Fill the water tank 43 with water. When the conveying assembly 11 operates, it drives the toggle rod 48 to move. When the toggle rod 48 moves to contact the cleaning brush 3, the toggle rod 48 toggles the right side of the cleaning brush 3 to swing upward, deforming the torsion spring 31. As a result, the left side of the cleaning brush 3 swings downward, causing the cleaning brush 3 to press the lower pressing plate 41 to move downward. The lower pressing plate 41 drives the piston rod of the air cylinder 4 to move downward, and the linear spring 42 is compressed. When the toggle rod 48 moves away from the cleaning brush 3, the torsion spring 31 resets, driving the cleaning brush 3 to reverse and reset. As a result, the cleaning brush 3 stops pressing the lower pressing plate 41, and the linear spring 42 resets, driving the piston rod of the air cylinder 4 and the lower pressing plate 41 to move upward and reset, causing the piston rod of the air cylinder 4 to pump the water in the water tank 43 into the air cylinder 4 through the water suction pipe 44. At this time, the one-way valve in the first water pipe 45 closes, and the one-way valve in the water suction pipe 44 opens. When the lower pressing plate 41 is squeezed by the cleaning brush 3 and moves downward again, it drives the piston rod of the air cylinder 4 to move downward, causing the water in the air cylinder 4 to be squeezed into the first water pipe 45, then into the second water pipe 46 and the third water pipe 49, and then sprayed out in an atomized form through the atomizing nozzle 47. At this time, the one-way valve in the first water pipe 45 opens, and the one-way valve in the water suction pipe 44 closes. In this way, while the conveying assembly 11 feeds the crushed raw materials, water spraying and dust reduction can be carried out, realizing intermittent water spraying, avoiding waste of water caused by continuous water spraying for a long time, and being able to prevent excessive water spraying from forming water flow and polluting the environment. Since the atomizing nozzle 47 of the third water pipe 49 is inclined, when the crushed raw materials fall onto the conveying assembly 11, the crushed raw materials can be sprayed and dust-reduced, further reducing dust dispersion, and the crushed raw materials can be wetted to reduce dust during subsequent crushing.

[0040] There are also two guide rails 5, and the two guide rails 5 are respectively fixedly connected inside the protective cover 13 and on the right side of the support frame 1. A protective curtain 51 is slidably connected between the left guide rail 5 and the right guide rail 5.

[0041] When conveying the crushed raw materials, the operator can pull the protective curtain 51 to open it, so that the protective curtain 51 unfolds around the guide rail 5. In this way, when conveying the crushed raw materials, dust can be blocked to further prevent dust dispersion. After completion, the protective curtain 51 can be retracted backward.

[0042] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The scope of the following claims should be given the broadest interpretation so as to cover all modifications and equivalent structures and functions.
