[0002] With the rapid development of the economy, the demand for crushed stones in the construction industry is also increasing. Currently, most large stones are put into a crusher for crushing, then transported to a hopper by a hoist, and screened by a vibrating feeder. Qualified stones are selected and finally transported to a storage bin, while unqualified stones are put back into the crusher for further crushing. A large amount of dust is generated during the crushing process.

[0003] Among them, the dust removal mechanism of a regenerated concrete aggregate crusher disclosed in the publication number CN214439944U includes an absorption cylinder, a dust collector, and a dust suction hopper covering the feeding port of the crusher. The air inlet of the dust collector is connected and fixedly connected to the dust suction hopper. The other end of the dust collector is connected and fixedly connected with a conveying pipe, and the other end of the conveying pipe is connected and fixedly connected to the lower end of the absorption cylinder. A filter plate is slidably connected to the absorption cylinder along the vertical direction under the conveying pipe. The absorption cylinder is provided with a driving component I for driving the filter plate to move vertically. Through the setting of the filter plate, water and dust can be separated, and through the driving component I, the filter plate is driven to move vertically, so that the dust in the absorption cylinder can be fished out.

[0004] This device sucks the dust into the interior of the absorption cylinder and then separates the dust and water body through a filter plate.

In order to ensure the dust treatment effect of the absorption cylinder, it is necessary to frequently stop the machine to deal with the dust, which in turn leads to a reduction in the crushing efficiency of the crushing mechanism for aggregates.

[0005] Therefore, it is very necessary to invent a dust removal mechanism for a regenerated concrete aggregate crusher to solve the above problems. Summary of the Utility Model

The right end of the transmission pipeline 21 is fixedly connected to the dust collector 11. A suction pipeline is fixedly connected to the right side of the dust collector 11. The right end of the suction pipeline extends into the interior of the crusher body 1. Clamping plates 28 are fixedly connected to the positions near the left end on the front and rear surfaces of the treatment box body 2.

The feed hole 42 communicates with the discharge port 27.

[0034] Among them, the crusher body 1 crushes the concrete aggregate, and the dust collector 11 sucks the dust generated during the crushing process. Then, the dust is conveyed into the interior of the treatment box body 2 through the transmission pipeline 21. At this time, the atomizing nozzle 24 inside the treatment box body 2 sprays water mist to adsorb the dust and make the dust land on the surface of the filter net 31. At the same time, the cleaning plate 38 is pushed to the left every other period of time to push the dust into the interior of the collection box 4 for collection, thereby realizing continuous cleaning of the dust without stopping the machine, improving the efficiency of dust cleaning, and at the same time improving the crushing efficiency.

[0035] Refer to Figure 2 and Figure 4, the left end of the transmission pipeline 21 is fixedly connected to the position near the upper side of the right surface of the crusher body 1, the water inlet pipeline 23 is fixedly connected to the upper surface of the crusher body 1, the drainage pipeline 22 is fixedly connected to the position near the lower side of the right surface of the treatment box body 2, a circulation pump 210 is installed on the right side of the treatment box body 2, one end of the drainage pipeline 22 away from the treatment box body 2 is fixedly connected to the water inlet of the circulation pump 210, one end of the water inlet pipeline 23 away from the treatment box body 2 is fixedly connected to the water outlet of the circulation pump 210, a three-component flow pipeline is fixedly connected to the surface of the water inlet pipeline 23, the lower end of the three-component flow pipeline penetrates through the inner top wall of the treatment box body 2 and extends into the interior of the treatment box body 2, and the atomizing nozzle 24 is fixedly connected to the lower end of the flow pipeline. The left end of the water inlet pipeline 23 is fixedly connected with a water delivery pipeline 211.

[0036] Specifically, in the initial state, water is conveyed into the interior of the water inlet pipeline 23 through the water delivery pipeline 211, and water mist is sprayed downward through the atomizing nozzle 24. After the water mist mixes with the dust and lands on the surface of the filter screen 31, part of the water body will penetrate through the filter screen 31 to the bottom end of the treatment box body 2. When there is a large amount of water stored at the bottom end of the treatment box body 2, the circulation pump 210 is started. The circulation pump 210 sucks the water body at the bottom end of the treatment box body 2 back into the interior of the water inlet pipeline 23 for recycling, thereby improving the utilization rate of water resources.

[0037] Refer to Figure 2 and Figure 5 , a plug-in groove 26 is provided on the inner wall of the treatment box body 2, a plug-in hole 25 is provided on the right surface of the treatment box body 2, a discharge port 27 is provided on the left surface of the treatment box body 2, a plug-in plate 32 is fixedly connected to the side surface of the filter plate 3, the plug-in plate 32 is slidably connected to the plug-in groove 26, the filter screen 31 is fixedly connected to the middle of the filter plate 3, a threaded rod 33 is rotatably connected to the left and right inner walls of the treatment box body 2, positioning rods 34 are arranged on both the front and rear sides of the threaded rod 33, and the left and right ends of the two groups of positioning rods 34 are respectively fixedly connected to the left and right inner walls of the treatment box body 2. An electric motor 37 is fixedly installed on the right surface of the treatment box body 2, and the output end of the electric motor 37 is fixedly connected to the right end of the threaded rod 33.

A cleaning plate 38 is fixedly connected to the lower ends of the second positioning block 36 and the first positioning block 35.

[0038] Meanwhile, during the process of cleaning the dust, the output end of the electric motor 37 drives the threaded rod 33 to rotate. At the same time, through the cooperation of the second positioning block 36 and the positioning rod 34, the threaded rod 33 drives the first positioning block 35 to slide to the left during rotation, thereby driving the cleaning plate 38 to slide to the left, pushing the dust on the surface of the filter net 31 to the left into the interior of the collection box 4. Then, the electric motor 37 reverses to move the cleaning plate 38 to the rightmost end. After a period of dust reduction, the cleaning plate 38 is pushed to the left again to clean the dust. During the cleaning process, the dust collector 11 continuously sucks the dust into the interior of the processing box body 2.

[0039] In addition, when the cleaning plate 38 slides to the right, due to continuous dust reduction treatment of the dust inside the processing box body 2, a very small amount of dust will be pushed to the rightmost end by the cleaning plate 38. After the aggregate crushing is completed, the equipment is shut down, and the filter plate 3 is pulled out to the right from the interior of the insertion hole 25 to perform high-pressure flushing on the surface of the filter net 31, flushing the remaining part of the dust on its surface to maintain the permeability of the filter net 31.

At this time, the atomizing nozzle 24 sprays water mist to adsorb the dust and make the dust land on the surface of the filter net 31. At the same time, the cleaning plate 38 is pushed to the left at regular intervals to push the dust into the interior of the collection box 4 for collection, thereby achieving continuous dust cleaning without shutting down, improving the dust cleaning efficiency, and at the same time improving the crushing efficiency.

[0041] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments.
