Description

Technical Field

[0001] This utility model belongs to the field of solid waste treatment technology, and in particular relates to a device for recovering coke crushing dust. Background Technology

[0002] Coke is a solid fuel, mainly composed of carbon, obtained by dry distillation of coal at high temperatures in an oxygen-free or low-oxygen environment. Different industrial production processes have varying requirements for coke particle size, therefore coke needs to be crushed before use. However, the crushing process generates a large amount of dust, which, if directly released into the atmosphere, would cause serious air pollution. To address this dust problem, the coke dust generated after crushing is processed through a coke crushing dust recovery device to reduce the concentration of coke dust in the air and decrease dust emissions.

[0003] However, the dust particles generated after coke crushing are very fine and easily adhere to the inner walls, gaps, and dead corners of equipment, forming a stubborn adhesion layer. In addition, during the crushing and pneumatic conveying process, the dust particles may become statically charged, making them even more likely to adhere to the equipment. In order to clean the coke dust adhering to the equipment, workers need to disassemble the equipment for cleaning, which increases the difficulty of cleaning. Therefore, a device for recycling coke crushing dust is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a device for recovering coke crushing dust, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An apparatus for recovering coke crushing dust, comprising:

[0007] The main body of the device includes an outer cylinder, a filter cylinder, an air inlet pipe, and an air outlet pipe. The filter cylinder is fixedly installed inside the outer cylinder and is coaxially arranged with the filter cylinder. The air inlet pipe is installed at the upper end of the outer cylinder and is connected to the gap between the outer cylinder and the filter cylinder. The air outlet pipe is installed at the lower end of the outer cylinder and is connected to the inside of the filter cylinder.

[0008] The dust removal structure includes fixed rods, dust removal brushes, and rotating rings. The dust removal brushes are evenly distributed on the fixed rods, and multiple fixed rods are provided. A pair of rotating rings are provided. The two ends of the fixed rods are respectively fixedly connected to the pair of rotating rings. The multiple fixed rods are spaced apart. The rotating rings are rotatably installed inside the outer cylinder. The dust removal brushes are attached to the outer wall of the filter cartridge near the inner wall of the outer cylinder.

[0009] In a further technical solution, the dust removal structure also includes a connecting rod, a rotating column, and a motor. The upper end of the outer cylinder has a mounting frame, and one of the upper end faces with a rotating ring has a fixed column. The two ends of the connecting rod are fixedly connected to the rotating column and the fixed column. The rotating column is rotatably mounted on the lower end face of the mounting frame. The motor is fixedly mounted on the upper end face of the mounting frame, and the output shaft of the motor is connected to the rotating column.

[0010] In a further technical solution, the main body of the device also includes a conical cylinder, which is fixedly installed at the lower end of the filter cylinder, and one end of the air outlet pipe extends into the interior of the conical cylinder.

[0011] In a further technical solution, the outer cylinder also includes a dust removal port and a dust removal door. The dust removal door is adapted to the dust removal port. The dust removal door is detachably disposed on the inner wall of the dust removal port, and the lower end of the dust removal door is disposed above one of the lower rotating rings.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figures 1 to 3 As shown, this utility model embodiment provides a device for recovering coke crushing dust, comprising:

[0025] The main body of the device 1 includes an outer cylinder 11, a filter cylinder 12, an air inlet pipe 13, and an air outlet pipe 14. The filter cylinder 12 is fixedly installed inside the outer cylinder 11 and is coaxially arranged with the filter cylinder 12. The air inlet pipe 13 is installed at the upper end of the outer cylinder 11 and is connected to the gap between the outer cylinder 11 and the filter cylinder 12. The air outlet pipe 14 is installed at the lower end of the outer cylinder 11 and is connected to the inside of the filter cylinder 12.

[0026] The dust removal structure 2 includes a fixed rod 21, a dust removal brush 22, and a rotating ring 23. The dust removal brush 22 is evenly distributed on the fixed rod 21. Multiple fixed rods 21 are provided, and a pair of rotating rings 23 are provided. The two ends of the fixed rod 21 are respectively fixedly connected to a pair of rotating rings 23. Multiple fixed rods 21 are spaced apart. The rotating rings 23 are rotatably installed inside the outer cylinder 11. The dust removal brush 22 is attached to the outer wall of the filter cylinder 12 near the inner wall of the outer cylinder 11.

[0027] In this embodiment, as gas is continuously introduced into the outer cylinder 11 through the inlet pipe 13 and discharged from the outside of the outer cylinder 11 through the outlet pipe 14, a layer of coke dust accumulates on the outer wall of the filter cylinder 12 near the outer cylinder 11. The rotating ring 23 drives multiple fixed rods 21 and cleaning brushes 22 evenly distributed on the fixed rods 21 to rotate around the outer cylinder 11 axially. The rotating cleaning brushes 22 clean the outer wall of the filter cylinder 12 to remove the layer of coke dust on the outer wall of the filter cylinder 12. There is no need for workers to disassemble the entire equipment, the operation is simple, and the maintenance cost is reduced.

[0028] Specifically, the dust removal structure 2 also includes a connecting rod 24, a rotating column 25, and a motor 26. The upper end of the outer cylinder 11 has a mounting frame 111, one of which has a fixed column 231 on its upper end face with a rotating ring 23. The two ends of the connecting rod 24 are fixedly connected to the rotating column 25 and the fixed column 231. The rotating column 25 is rotatably mounted on the lower end face of the mounting frame 111. The motor 26 is fixedly mounted on the upper end face of the mounting frame 111, and the output shaft of the motor 26 is connected to the rotating column 25.

[0029] In this embodiment, after the motor 26 is started, it drives the rotating column 25 to rotate, which in turn drives the connecting rod 24 to rotate as well, so that the fixed column 231 located at the other end of the connecting rod 24 rotates axially around the outer cylinder 11.

[0030] Specifically, the main body 1 of the device also includes a conical cylinder 15, which is fixedly installed at the lower end of the filter cylinder 12, and one end of the air outlet pipe 14 extends into the interior of the conical cylinder 15.

[0031] Specifically, the outer cylinder 11 also includes a dust removal port 112 and a dust removal door 113. The dust removal door 113 is adapted to the dust removal port 112. The dust removal door 113 is detachably disposed on the inner wall of the dust removal port 112, and the lower end of the dust removal door 113 is disposed above one of the lower rotating rings 23.

[0032] In this embodiment, under the action of gravity, the coke dust layer is swept to the upper surface of the rotating ring 23 below; the worker opens the dust removal door 113 and collects the coke dust layer on the rotating ring 23 from the dust removal port 112, so as to facilitate the secondary use of the coke dust layer.

[0033] Specifically, the air inlet pipe 13 has an air inlet 131 and an air outlet 132. A pair of air outlets 132 are provided, and the pair of air outlets 132 are symmetrically distributed with the air inlet 131 as the center. Both pairs of air outlets 132 extend into the interior of the outer cylinder 11.

[0034] In this embodiment, gas containing coke dust is introduced through the air inlet 131 on the air inlet pipe 13, and then enters the filter cartridge 12 and the interior of the outer cylinder 11 through a pair of air outlets 132. By providing a pair of air outlets 132, the coke dust can be more evenly distributed inside the outer cylinder 11.

[0035] Specifically, the filter cartridge 12 is provided with a sealing plate 121 at one end away from the conical cartridge 15, and the side wall of the sealing plate 121 is in contact with the inner wall of one of the upper rings 23.

[0036] The working principle of this utility model is as follows:

[0037] First, gas containing coke dust is introduced through the inlet 131 on the inlet pipe 13, and then enters the filter cartridge 12 and the inner cylinder 11 through a pair of outlets 132. By setting a pair of outlets 132, the coke dust can be more evenly distributed inside the outer cylinder 11.

[0038] Subsequently, the coke dust in the gas is adsorbed on the outer wall of the filter cartridge 12 near the outer cylinder 11, and the filtered gas passes through the filter cartridge 12 and is discharged outside the outer cylinder 11 via the gas outlet pipe 14 connected to the conical cylinder 15 at the lower end of the filter cartridge 12.

[0039] As gas is continuously introduced into the outer cylinder 11 through the inlet pipe 13 and discharged from the outside of the outer cylinder 11 through the outlet pipe 14, a layer of coke dust accumulates on the outer wall of the filter cartridge 12 near the outer cylinder 11; after starting, the motor 26 drives the rotating column 25 to rotate, which in turn drives the connecting rod 24 to rotate as well, so that the fixed column 231 located at the other end of the connecting rod 24 rotates around the outer cylinder 11 axially.

[0040] The rotating ring 23 drives multiple fixed rods 21 and cleaning brushes 22 evenly distributed on the fixed rods 21 to rotate around the outer cylinder 11 axially. The rotating cleaning brushes 22 clean the outer wall of the filter cylinder 12 to remove the coke dust layer on the outer wall of the filter cylinder 12. There is no need for workers to disassemble the entire equipment, making operation simple and reducing maintenance costs.

[0041] Under the influence of gravity, the coke dust layer is swept to the upper surface of the rotating ring 23 below; the worker opens the dust removal door 113 and collects the coke dust layer on the rotating ring 23 from the dust removal port 112, so as to facilitate the secondary use of the coke dust layer.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
