Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction of crushers, in particular to dust reduction equipment used for crushers. Background Art

[0002] Crusher is a key equipment used for stone crushing, which breaks stones into small particles through impact and extrusion. However, this process will generate dust and noise pollution, which is harmful to human health and the environment. People may experience health problems such as blurred vision and hearing loss after long-term exposure to such an environment, and even cause damage to the respiratory system. Therefore, it is crucial to remove dust and reduce noise from the crusher.

[0003] At present, there are some challenges in dust removal and noise reduction for crushers. When using bag dust collectors, their non-continuous cleaning leads to significant air leakage in the grid wheel. In addition, the filter area of ​​the bag dust collector may be too small, and the actual exhaust volume is insufficient, making it difficult to form a micro-negative pressure in the crusher discharge port and the crusher cavity, resulting in a lot of dust in the workplace environment. In order to reduce dust, water is often sprayed at the entrance of the crusher in actual operation, but this may aggravate the sticking of the filter bags of the bag dust collector and the blockage of the feeder, thereby reducing the dust removal effect.

[0004] In terms of dust collection, there are also some problems with using a grid wheel to transport the dust captured by the bag dust collector. This may lead to increased power consumption and increased mechanical maintenance workload. Frequent disassembly of the grid wheel feeder may also cause air leakage in the flange, which in turn aggravates air leakage in the ash hopper, making it impossible to effectively collect dust.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 - Figure 5 As shown, a dust reduction device for a crusher includes a housing 1, a transmission device 2, a drive device 3, a crushing assembly 4 and a discharge port 5. The transmission device 2 and the drive device 3 are mounted on the housing 1, and the crushing assembly 4 is mounted in the housing 1. The drive device 3 and the transmission device 2 work together to drive the crushing assembly 4 to crush materials. The discharge port 5 is located at the lower end of the crushing assembly 4 and is used to discharge the crushed materials.

[0025] The discharge port 5 is connected to a feed pipe 7, and a conveying pipe 8 is provided at the lower end of the pipe. A discharge port 9 is provided at the other end of the conveying pipe 8 for discharging materials. A spiral feeding assembly 11 is provided in the conveying pipe 8, and the assembly is driven by a servo motor 10. The servo motor 10 is mounted on the housing 1 through a bracket and fasteners, and is fixed to the spiral feeding assembly 11 by bolts. The spiral feeding assembly 11 includes a round rod and a spiral feeding member, and the spiral feeding member is welded to the round rod. The round rod passes through the covers at both ends of the conveying pipe 8, and a mechanical seal is achieved between the covers, and at the same time passes through the bearings provided on the covers.

[0026] The side wall of the delivery pipe 8 is provided with a hole, and an arc-shaped filter screen 13 is installed. The arc-shaped filter screen 13 is composed of an arc-shaped grid frame and an arc-shaped filter screen, and the arc-shaped filter screen is welded on the arc-shaped grid frame and fixed on the delivery pipe 8 by bolts. The arc-shaped filter screen 13 is used to filter dust particles.

[0027] The arc filter 13 is covered with a mounting frame 12, which is connected to the side wall of the conveying pipe 8. The lower end of the mounting frame 12 is connected to an ash collecting hopper 14, and a sealing strip is provided at the connection between the ash collecting hopper 14 and the mounting frame 12. An ash collecting water tank 15 is provided in the ash collecting hopper 14 for collecting dust.

[0028] The feed pipe 7 is fixed to the discharge port 5 by bolts and kept sealed. The feed pipe 7 is fixed to the conveying pipe 8 by welding, and the discharge port 9, the mounting frame 12 and the conveying pipe 8 are also fixed by welding. When the spiral feeding assembly 11 drives the crushed material to pass through the arc filter 13, the dust particles will fall into the dust collection tank 15 for collection; the crusher dust reduction device realizes the effective collection and treatment of the dust generated in the crushing process through the effective structural design and the coordinated work of the components, thereby achieving the purpose of dust reduction.

[0029] Working process: After the material is crushed by the crushing component 4, it will fall into the feed pipe 7 through the discharge port 5. Then, the material enters the conveying pipe 8 from the feed pipe 7. At this time, the spiral feeding component 11 starts to work, driven by the servo motor 10, driving the round rod and the spiral feeding piece to rotate, and pushing the material forward in a spiral manner; in this process, due to the design of the spiral feeding piece, the material forms a certain pressure in the conveying pipe 8, and this pressure helps to push the material to the discharge port 9 more smoothly. At the same time, due to the rotation of the spiral feeding piece, most of the dust particles in the material will be thrown to the inner wall of the conveying pipe 8; an arc-shaped filter screen 13 is provided on the inner wall of the conveying pipe 8, which can intercept the dust particles thrown to the inner wall and prevent them from being discharged with the material. The dust particles will fall into the ash hopper 14 under the installation frame 12 under the action of gravity; the design of the ash hopper 14 allows the dust particles to fall into it smoothly without being retained in the conveying pipe 8. At the same time, an ash collecting trough 15 is provided in the ash collecting hopper 14. When dust falls into the ash collecting trough 15, it will be moistened by the water therein, further preventing the dust from being blown up, thereby achieving a better dust reduction effect. In this way, the crusher dust reduction equipment successfully realizes the effective collection and treatment of dust during the discharging process, which not only improves the quality of the working environment, but also protects the health of the operators.

[0030] The utility model can effectively throw dust particles in the material toward the inner wall of the conveying pipe through the rotation of the spiral feeding assembly, and then be intercepted by the arc filter. This design can greatly improve the dust reduction efficiency and significantly reduce dust pollution during material discharge; the dust particles intercepted by the arc filter fall into the ash hopper under the action of gravity, realizing the centralized collection of dust. The ash collection trough in the ash hopper can moisten the dust and prevent it from being raised again, thereby further enhancing the dust reduction effect; through effective dust reduction, the quality of the working environment is significantly improved, and the health risks faced by operators due to long-term exposure to dusty environments are reduced;

[0031] The above are the preferred embodiments of the utility model and the technical principles used therein. For those skilled in the art, without departing from the spirit and scope of the utility model, any obvious changes such as equivalent transformation, simple replacement, etc. based on the technical solution of the utility model shall fall within the protection scope of the utility model.
