Technical Field

[0001] This utility model relates to the field of crusher technology, specifically a dust prevention device for crushers. Background Technology

[0002] Dust is often generated during the operation of a crusher, which pollutes the working environment and can affect the health of personnel if inhaled. Therefore, dust control equipment is needed to deal with it.

[0003] Currently used dust control devices for crushers often lack easy disassembly of the filter plates, requiring maintenance personnel to spend a significant amount of time during maintenance. This increases the difficulty and time cost of maintenance, greatly prolongs downtime, and affects subsequent production efficiency. Furthermore, most of these devices cannot adjust the fan speed according to dust concentration, leading to increased energy waste or reduced dust adsorption effectiveness, thus diminishing the device's practicality.

[0004] In summary, this utility model solves the problems in the background art by designing a dust prevention device for a crusher. Utility Model Content

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0027] A dustproof device for a pulverizer includes a pulverizer body 1 and a dustproof box 2 located at the right end of the pulverizer body 1. A dust concentration sensor 3 is located on the right side of the pulverizer body 1. A connecting pipe 4 is located on the top of the dustproof box 2. A controller 5 and a centrifugal fan 6 are located on the rear side of the dustproof box 2. A first filter plate 7, a second filter plate 8, and a third filter plate 9 are respectively sealed and passed through the right side of the dustproof box 2. An electrostatic screen 701 is located on the top of the first filter plate 7. A coarse screen 801 is located on the top of the second filter plate 8. A fine screen 901 is located on the top of the third filter plate 9. A connecting mechanism 10 is provided between the first filter plate 7, the second filter plate 8, the third filter plate 9 and the dustproof box 2.

[0028] Specifically, the end of the connecting pipe 4 away from the dust box 2 extends into the interior of the crusher body 1, the detection end of the dust concentration sensor 3 penetrates through the right side surface of the crusher body 1 and extends inward, the centrifugal fan 6 is a variable speed fan, and the centrifugal fan 6 and the dust concentration sensor 3 are electrically connected to the controller 5 through wires respectively.

[0029] In this embodiment, the centrifugal fan 6 is mainly used to draw dust from the pulverizer body 1 into the dust box 2 through the connecting pipe 4. The dust concentration sensor 3 can monitor the dust concentration in the pulverizer body 1 and feed it back to the controller 5, which then controls the centrifugal fan 6 to adjust its speed.

[0030] Specifically, the top surfaces of both the coarse screen 801 and the fine screen 901 are coated with polytetrafluoroethylene. The shapes and structures of filter plates 7, 8, and 9 are consistent. The outer surfaces of filter plates 7, 8, and 9 are all in contact with the inner wall of the dust box 2. Filter plates 7, 8, and 9 are distributed at equal intervals on the surface of the dust box 2.

[0031] In this implementation scheme, the dust removal effect of the device is improved by the layered interception of the electrostatic screen 701, the coarse screen 801 and the fine screen 901, thus meeting the dust prevention requirements of the crusher.

[0032] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The connecting mechanism 10 includes a positioning post 1001, a magnetic suction hole 1002, a positioning hole 1003, and a magnetic suction post 1004. The positioning post 1001 and the magnetic suction hole 1002 are both located on the right side surface of the dust box 2. A locking block 1005 is provided at the right end of the positioning post 1001. The positioning hole 1003 and the magnetic suction post 1004 are respectively located on the right side surface of the first filter plate 7, the second filter plate 8, and the third filter plate 9.

[0033] Specifically, the magnetic column 1004 is magnetically connected to the magnetic hole 1002, the outer surface of the positioning column 1001 is fitted with the inner wall of the positioning hole 1003, and the locking block 1005 rotates eccentrically with the right end of the positioning column 1001 through the rotating shaft.

[0034] In this embodiment, the positioning post 1001 is mainly used to form an interlocking contact with the positioning hole 1003, which can effectively prevent the positional displacement of filter plate 7, filter plate 8, filter plate 9 and dust box 2. With the magnetic attraction of the magnetic post 1004 and the magnetic hole 1002, the filter plate 7, filter plate 8, filter plate 9 and dust box 2 are quickly contacted. Under the eccentric rotation of the locking block 1005 and the positioning post 1001, the locking block 1005 forms a mechanical self-lock with the right side surface of filter plate 7, filter plate 8, filter plate 9, and filter plate 9, thus meeting the subsequent disassembly requirements of the filter plates.

[0035] The working process of this utility model is as follows: When using a dustproof device for a pulverizer, the pulverizer body 1 is operated, and dust is generated in the pulverizer body 1. The dust concentration sensor 3 can monitor the dust concentration. When the concentration is low, the controller 5 controls the centrifugal fan 6 to rotate at a low speed. When the concentration is high, the controller 5 controls the centrifugal fan 6 to rotate at a high speed. This helps to save energy and ensures the adsorption effect of dust. Under the action of the centrifugal fan 6, the dust enters the dustproof box 2 through the connecting pipe 4 and is sequentially exposed to the electrostatic screen. 701, coarse screen 801, and fine screen 901 come into contact, thereby achieving dust filtration. When it is necessary to disassemble filter plate 7, filter plate 8, and filter plate 9, rotate locking block 1005 until locking block 1005 is completely disengaged from the right side surface of filter plate 7, filter plate 8, and filter plate 9. Pull filter plate 7, filter plate 8, and filter plate 9 outward until the magnetic attraction disappears, and they can be removed. This facilitates the disassembly and replacement of filter plate 7, filter plate 8, and filter plate 9, meeting the needs of users.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
