[0008] Preferably, the integrated dust collector is externally connected to the crusher housing and the return feed rack by fixing screws. The outer surface of the integrated dust collector is provided with an integrally formed air inlet channel. The position of the air inlet channel corresponds to the crushing position of the crusher housing. An air guide pipe is installed on the outside of the integrated dust collector, and the air outlet of the air guide fan is connected to the air inlet channel through the air guide pipe.

[0009] Preferably, the centrifugal glass wool is attached to the inner wall of the integrated dust collector and bonded to the integrated dust collector. The centrifugal glass wool is used to absorb the noise generated by the crushing of aluminum ash slag.

[0010] Preferably, a feed hopper is installed at the upper end of the crusher shell, a crushing mechanism is installed inside the feed hopper, a geared motor is installed on one side of the crushing mechanism, and the motor shaft of the geared motor is connected to the crushing mechanism through gears and couplings.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The integrated dust collector frame above the feeding rack and crusher housing of this utility model has the ability to remove dust and reduce noise. During use, the aluminum ash slag is driven to the feed hopper by the conveyor belt in the feeding rack, and then crushed by the crushing mechanism. The dust generated by crushing and conveying is first blocked by the integrated dust collector frame. The guide fan blows air into the air inlet channel, and the wind force causes large dust particles to settle to the bottom of the feed hopper in advance, reducing the load on the subsequent purification unit and maintaining the working environment. In addition, the centrifugal glass wool absorbs dust. The internal fibers of the centrifugal glass wool have a three-dimensional network structure. When sound waves enter, they are converted into heat energy due to air viscosity resistance, which greatly improves the absorption coefficient of mid-frequency noise. During the filtration process, clean water is pumped in by the water pump, and the water pipe and spray head spray the surface of the filter plate. The dust is subjected to the gravity of the water and falls onto the filter plate, preventing the dust from flying. The first buffer discharge plate and the second buffer discharge plate set below the filter plate reduce the impact force generated by the falling aluminum ash slag and buffer the discharge to reduce the dust generated by the falling, thus fully protecting the working environment.

[0016] 2. After crushing aluminum ash slag, the crushing mechanism of this utility model performs filtration through a filter plate. The cam is driven to rotate by a servo motor. The cam rotates on the upper end of the gear fan, causing the gear fan to swing. The gear fan drives the connecting support rod to make the filter plate move back and forth, thus moving the aluminum ash slag on the surface of the filter plate to improve the filtration efficiency. One end of the filter plate is connected to a return feeder, which performs secondary crushing of the aluminum ash slag to improve the crushing effect and facilitate continuous operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To address the issue of dust generation affecting the working environment during the actual use of existing aluminum ash and slag crushing equipment, please refer to [link / reference needed]. Figure 1 - Figure 3 This embodiment provides the following technical solution:

[0024] The crushing device for aluminum ash clinker includes a feeding rack 1 and a crusher shell 4. The feeding rack 1 is installed at the front end of the crusher shell 4. A return rack 3 is installed on one side of the middle of the crusher shell 4. An integrated dust collector 2 is installed above the feeding rack 1 and the crusher shell 4. A guide fan 202 is installed on the outside of the integrated dust collector 2, and centrifugal glass wool 203 is installed inside the integrated dust collector 2. The integrated dust collector 2 installed above the feeding rack 1 and the crusher shell 4 has the ability to remove dust and reduce noise.

[0025] The integrated dust collector 2 is externally connected to the crusher housing 4 and the return feed rack 3 by fixing screws. The outer surface of the integrated dust collector 2 is provided with an integrally formed air inlet channel 204. The position of the air inlet channel 204 corresponds to the crushing position of the crusher housing 4. The integrated dust collector 2 is externally installed with an air guide pipe 201. The air outlet of the air guide fan 202 is connected to the air inlet channel 204 through the air guide pipe 201. The air guide fan 202 blows air into the air inlet channel 204, using the air force to make large dust particles settle to the bottom of the feed hopper 402 in advance, reducing the load on the subsequent purification unit and maintaining the working environment.

[0026] Centrifugal glass wool 203 is attached to the inner wall of the integrated dust collector 2 and bonded to the integrated dust collector 2. Centrifugal glass wool 203 is used to absorb the noise generated by the crushing of aluminum ash slag. While absorbing dust, the internal fibers of centrifugal glass wool 203 form a three-dimensional network structure. After sound waves enter, they are converted into heat energy due to air viscosity resistance, which greatly improves the absorption coefficient of mid-frequency noise.

[0027] A feed hopper 402 is installed at the upper end of the crusher shell 4. A crushing mechanism 401 is installed inside the feed hopper 402. A geared motor 403 is installed on one side of the crushing mechanism 401. The motor shaft of the geared motor 403 is connected to the crushing mechanism 401 through gears and couplings. The dust generated by crushing and conveying through the crushing mechanism 401 is first sealed by the integrated dust collector 2.

[0028] A water pump 407 is installed on the outside of the crusher housing 4. A water guide pipe 408 is installed at one end of the water pump 407. The water guide pipe 408 extends into the inside of the crusher housing 4 and is fixedly connected to the crusher housing 4. A spray head 409 is provided on the outside of the water guide pipe 408. The spray position of the spray head 409 corresponds to the material feeding position of the crushing mechanism 401. During the filtration process, clean water is drawn in by the water pump 407. The water guide pipe 408 and the spray head 409 spray the surface of the filter plate 404. Dust is affected by the gravity of the water and falls onto the filter plate 404, preventing dust from flying.

[0029] A filter plate 404 is installed in the middle of the inside of the crusher housing 4. The filter plate 404 is obliquely arranged below the crushing mechanism 401, and the lower end of the filter plate 404 is abutted and connected to the upper end of the return material rack 3. A first buffer discharge plate 405 and a second buffer discharge plate 406 are arranged below the filter plate 404. The first buffer discharge plate 405 and the second buffer discharge plate 406 are used to buffer the falling speed of aluminum ash slag to reduce the dust generated during material feeding.

[0030] Specifically, the integrated dust collector 2 installed above the feeding rack 1 and the crusher casing 4 has the ability to remove dust and reduce noise. During use, the aluminum ash slag is driven to the feed hopper 402 by the conveyor belt 101 inside the feeding rack 1, and then crushed by the crushing mechanism 401. The dust generated from crushing and conveying is first blocked by the integrated dust collector 2. The guide fan 202 blows air into the air inlet channel 204, using the wind power to make large dust particles settle to the bottom of the feed hopper 402 in advance, reducing the load on the subsequent purification unit and maintaining the working environment. In addition, the centrifugal glass wool 203 absorbs dust while centrifuging the glass wool. The internal fibers of cotton 203 have a three-dimensional network structure. When sound waves enter, they are converted into heat energy due to air viscosity resistance, which greatly improves the absorption coefficient of mid-frequency noise. During the filtration process, clean water is pumped in by water pump 407, and water guide pipe 408 and spray head 409 spray the surface of filter plate 404. Dust falls onto filter plate 404 due to the gravity of water, preventing dust from flying. The first buffer discharge plate 405 and the second buffer discharge plate 406 set under filter plate 404 reduce the impact force generated by the falling aluminum ash slag, buffer the discharge, reduce the dust generated by falling, and fully protect the working environment.

[0031] To address the problem in existing aluminum ash crushing devices where aluminum ash that cannot be filtered through the filter holes is inconvenient to discharge and affects continuous operation, please refer to [the relevant documentation]. Figure 1 - Figure 4 This embodiment provides the following technical solution:

[0032] The feeding rack 1 is equipped with a conveyor belt 101. The lower end of the return rack 3 is fixedly installed with a sliding plate 301. The lower end of the sliding plate 301 extends to the lower end of the feeding rack 1. One end of the filter plate 404 is connected to the return rack 3. The aluminum ash slag is crushed in a secondary manner through the return rack 3 to improve the crushing effect and facilitate continuous operation.

[0033] A connecting rod 4041 is fixedly connected to the rear end of the filter plate 404. Both ends of the connecting rod 4041 extend into the interior of the crusher housing 4 and are slidably connected to the crusher housing 4. A gear sector 4042 is provided at the upper end of the connecting rod 4041. The gear sector 4042 is meshed with the connecting rod 4041. A cam 4043 is installed at the rear end of the gear sector 4042. A servo motor 4044 is installed at the rear end of the cam 4043. The motor shaft of the servo motor 4044 is connected to the gear sector 4044 through the cam 4043. 2. Transmission connection: The gear sector 4042 is rotatably connected to the crusher housing 4 via bearings. After crushing aluminum ash slag, the crushing mechanism 401 performs filtration through the filter plate 404. The cam 4043 is driven to rotate by the servo motor 4044. The cam 4043 rotates at the upper end of the gear sector 4042, causing the gear sector 4042 to swing. The gear sector 4042 drives the connecting support rod 4041 to make the filter plate 404 reciprocate, thus moving the aluminum ash slag on the surface of the filter plate 404 to improve filtration efficiency.

[0034] Specifically, after crushing the aluminum ash slag, the crushing mechanism 401 performs filtration through the filter plate 404. The cam 4043 is driven to rotate by the servo motor 4044. The cam 4043 rotates on the upper end of the gear fan 4042, causing the gear fan 4042 to swing.

One end of the filter plate 404 is connected to the return rack 3, which performs secondary crushing of the aluminum ash slag to improve the crushing effect and facilitate continuous operation.

[0035] Working Principle: During operation, aluminum ash slag is lifted to the feed hopper 402 by the conveyor belt 101 within the feeding rack 1. It is then crushed by the crushing mechanism 401. The dust generated from crushing and conveying is first-layered by the integrated dust collector 2. The blower 202 blows air into the air inlet channel 204, using wind power to pre-settle large dust particles to the bottom of the feed hopper 402, reducing the load on subsequent purification units and maintaining a clean working environment. Meanwhile, centrifugal glass wool 203 absorbs dust. The internal fibers of the centrifugal glass wool 203 have a three-dimensional network structure; when sound waves enter, they are converted into heat energy due to air viscosity resistance, greatly improving the absorption coefficient of mid-frequency noise. During filtration, the filter plate 404 performs the filtration work. A servo motor 4044 drives the cam 4043 to rotate. The cam 4043... The upper end of the wheel fan 4042 rotates, driving the gear fan 4042 to swing. The gear fan 4042 drives the connecting support rod 4041 to make the filter plate 404 reciprocate, thus moving the aluminum ash on the surface of the filter plate 404 to improve filtration efficiency.

Clean water is pumped in by the water pump 407, and the water guide pipe 408 and spray head 409 spray the surface of the filter plate 404. Dust falls onto the filter plate 404 due to the gravity of the water, preventing dust from flying. The first buffer discharge plate 405 and the second buffer discharge plate 406 are set below the filter plate 404 to reduce the impact force of the falling aluminum ash and buffer the discharge to reduce the dust generated by the falling and fully protect the working environment.
