Description

Technical Field

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

[0002] Graphite is the name of a mineral whose main component is carbon. It is usually found in metamorphic rocks and is formed when coal or carbonaceous rocks are subjected to regional metamorphism or magma intrusion.

[0003] During graphite production, dust is generated in the workshop. The dust contains graphite particles, which can cause harm to the human body after inhalation, and needs to be removed. The existing graphite dust removal device needs to use an exhaust fan to suck air and dust into the collection device when in use. In order to prevent dust from entering the exhaust fan and damaging the exhaust fan, a filter plate is provided in front of the exhaust fan to block the dust. However, after long-term use, the filter needs to be taken out and cleaned to prevent it from being blocked. The filter plate is located inside the device and is inconvenient to take out. At the same time, when the dust removal direction needs to be changed, the direction of the exhaust pipe needs to be changed, and the position of the entire device needs to be adjusted, which is extremely inconvenient. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a dust removal device for graphite production, which has the advantages of easy removal of the filter plate and convenient rotation, and solves the problems raised by the above background technology.

[0005] The utility model provides the following technical solution: a dust removal device for graphite production, comprising a box body, an exhaust fan fixedly installed on the outer wall of the box body, an inner wall of the box body rotatably connected to a rotating tube, an inner wall of the box body rotatably connected to a rotating rod, an inner wall of the box body slidably connected to a collecting box, an outer wall of the rotating rod is provided with a worm, an outer wall of the rotating tube is fixedly sleeved with a turbine, an inner wall of the box body is fixedly installed with a guide plate, an inner wall of the box body is slidably connected to a pulling plate, an inner wall of the rotating tube is fixedly sleeved with an absorption tube, a filter plate is fixedly installed on the inner wall of the pulling plate, a fixed shell is fixedly installed on the inner wall of the box body, an inner wall of the fixed shell is slidably connected to a locking pin, a limiting rod and a pulling plate are respectively fixedly installed on the outer walls of the locking pin, and a spring is provided on the inner wall of the fixed shell.

[0010] As a preferred technical solution of the present invention, a square groove is provided on the outer wall of the pulling plate, and the size of the square groove is adapted to the size of the side of the locking pin away from the fixed shell.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The dust removal device for graphite production pulls the pull plate, which drives the lock pin to move, and the lock pin drives the limit rod to move, thereby contracting the spring. When the lock pin completely enters the interior of the fixed shell, the lock pin is disengaged from the inner wall of the square groove on the outer wall of the pull plate, thereby eliminating the fixing relationship of the pull plate.

A spring 15 is provided on the inner wall of the fixed shell 12. In the above structure, there are two guide plates 8, and the two guide plates 8 are symmetrically distributed on both sides of the inner wall of the box body 1, and the lowest point of the two guide plates 8 is located above the collection box 5. The dust is gathered to the inside of the exhaust fan 2 through the two guide plates 8.

[0023] In a preferred embodiment, the worm 6 is at the same height as the turbine 7, and the outer walls of the worm 6 and the turbine 7 are adapted to each other. In the above structure, by rotating the rotating rod 4, the rotating rod 4 drives the worm 6 to rotate, and by meshing the worm 6 and the outer wall of the turbine 7, the worm 6 rotates while driving the turbine 7 to rotate, and the turbine 7 drives the rotating tube 3 to rotate, and the rotating tube 3 drives the absorption tube 10 to rotate.

[0024] In a preferred embodiment, the rotating rod 4 is provided with a hexagonal block at the end away from the worm 6, and the hexagonal block is compatible with a conventional wrench. In the above structure, when the worker needs to rotate the rotating rod 4, the hexagonal block outside the rotating rod 4 is rotated by using a conventional wrench, so that the rotating rod 4 rotates in the direction in which the worker rotates the wrench.

[0025] In a preferred embodiment, the box body 1 is provided with a notch near the pull plate 16, and the pull plate 16 reaches the outside of the box body 1 through the notch. In the above structure, by pulling the part of the pull plate 16 located outside the box body 1, the pull plate 16 drives the locking pin 13 located inside the box body 1 to move.

[0026] In a preferred embodiment, a circular groove is provided on the outer wall of the fixed shell 12, and the diameter of the circular groove is adapted to the diameter of the limiting rod 14. The limiting rod 14 is located in the circular groove on the outer wall of the fixed shell 12. In the above structure, the limiting rod 14 is located in the circular groove on the outer wall of the fixed shell 12, so that the limiting rod 14 is limited by the fixed shell 12, so that the locking pin 13 is limited, and thus the locking pin 13 cannot be tilted when it moves.

[0027] In a preferred embodiment, a square groove is provided on the outer wall of the pulling plate 9, and the size of the square groove is adapted to the size of the side of the locking pin 13 away from the fixed shell 12.

[0028] The working principle is to start the exhaust fan 2, which will then extract the air from the inside of the box 1. At this time, the air pressure inside the box 1 is reduced, and the absorption tube 10 generates suction through the air pressure difference between the box 1 and the outside, so that the absorption tube 10 draws the external air and dust into the inside of the box 1. The air sucked into the inside of the box 1 is continued to be extracted by the exhaust fan 2. The air drawn into the inside of the box 1 is blocked by the filter plate 11, so that it cannot leave from the inside of the box 1, and finally falls on the top of the guide plate 8 or the inner wall of the collection box 5. The dust on the top of the guide plate 8 moves to the inside of the collection box 5 through the slope of the guide plate 8. The collection box 5 can be taken out regularly for cleaning. When the direction of the absorption tube 10 needs to be changed, the rotating rod 4 is rotated by using a hexagonal wrench, so that the rotating rod 4 drives the worm 6 to rotate, and the rotation of the worm 6 drives the turbine 7 to rotate, and the turbine 7 drives the rotating tube 3 to rotate, and then the rotating tube 3 drives the absorption tube 10 to rotate, so that the direction of the air intake of the absorption tube 10 changes. When the filter plate 11 needs to be removed for cleaning, the pull plate 16 is pulled, so that the pull plate 16 drives the locking pin 13 to move. When the locking pin 13 moves to the inside of the fixed shell 12, the locking pin 13 is separated from the square groove on the outer wall of the pulling plate 9. At this time, the pulling plate 9 is pulled, so that the pulling plate 9 drives the filter plate 11 to be removed from the inner wall of the box body 1 for cleaning.
