Description
Technical Field
[0001] The utility model relates to the technical field of concrete accelerator production, and specifically belongs to a quick-setting agent crushing device with a dust reduction function. Background Technique
[0002] During the production of powder-type concrete accelerators, the raw materials need to be crushed by a crusher 2. The materials are crushed step by step from large to small, and after crushing, they are discharged from the discharge port 8 of the crusher 2, and then stirred and mixed with other materials to form a finished accelerator. When crushing the raw materials of the accelerator, a large amount of dust will be generated. The dust floating in the air will not only pollute the environment, but also cause the staff to inhale a large amount of dust and thus contract respiratory diseases, which will endanger the health of the staff. Content of the Utility Model
[0003] In order to overcome the problems existing in the background technique, the utility model provides a quick-setting agent crushing device with a dust reduction function to solve the technical problems proposed in the background technique that when crushing the raw materials of the quick-setting agent, a large amount of dust will be generated, and the dust floating in the air will not only pollute the environment, but also cause the staff to inhale a large amount of dust and thus contract respiratory diseases, which will endanger the health of the staff.
[0004] To achieve the above object, the utility model is realized through the following technical solutions:
[0005] A quick-setting agent crushing device with a dust reduction function includes a support frame 1, a crusher 2, a dust suction nozzle 3, a filter box 4, a sedimentation tank 5, and a negative pressure pump 6; the crusher 2, the filter box 4, the sedimentation tank 5, and the negative pressure pump 6 are installed on the support frame 1; the dust suction nozzles 3 are respectively installed on the feed port 7 and the discharge port 8 of the crusher 2 and are connected to the side wall of the filter box 4 through a connecting pipe 9; the filter box 4 is connected to the side wall of the sedimentation tank 5 through the connecting pipe 9, and the connecting pipe 9 extends into the liquid level of the liquid contained in the sedimentation tank 5; the side wall of the sedimentation tank 5 is connected to the negative pressure pump 6 through the connecting pipe 9.
[0006] Preferably, a filter screen 10 for filtering large-particle raw materials is provided at the air outlet of the filter box 4.
[0007] Preferably, a cylindrical connection port is provided at the bottom of the filter box 4, and a storage tank 11 is connected to the connection port by a thread.
[0008] Preferably, the opening structure of the dust suction nozzle 3 is an arc structure corresponding to the edges of the feed port 7 and the discharge port 8.
[0009] The beneficial effects of the present utility model are as follows: By means of a negative pressure pump, the present utility model generates negative pressure at the dust suction nozzle, absorbs the dust generated at the feeding port and discharging port of the crusher, and absorbs and treats the dust through a filter box and a sedimentation box, and then discharges the treated air into the atmosphere, thereby avoiding a large amount of dust floating in the air, polluting the air environment, and avoiding harming the physical health of the staff.

[0013] In order to make the objectives, technical solutions and beneficial effects of the present utility model clearer, the following will, in conjunction with the drawings, provide a detailed description of the preferred embodiments of the present utility model to facilitate the understanding of those skilled in the art.
[0014] As Figures 1 - 3 shown, the present utility model provides a quick-setting agent crushing device with a dust reduction function, including a support frame 1, a crusher 2, a dust suction nozzle 3, a filter box 4, a sedimentation box 5, and a negative pressure pump 6; the crusher 2, the filter box 4, the sedimentation box 5, and the negative pressure pump 6 are installed on the support frame 1; the dust suction nozzles 3 are respectively installed on the feeding port 7 and the discharging port 8 of the crusher 2 and are connected to the side wall of the filter box 4 through a connecting pipe 9; the filter box 4 is connected to the side wall of the sedimentation box 5 through the connecting pipe 9, and the connecting pipe 9 extends into the liquid level in the sedimentation box 5; the side wall of the sedimentation box 5 is connected to the negative pressure pump 6 through the connecting pipe 9. The negative pressure pump 6 generates negative pressure at the dust suction nozzle 3 to absorb the dust generated at the feeding port 7 and the discharging port 8 of the crusher 2. The dust enters the filter box 4 through the connecting pipe 9, and the large-particle raw materials that are absorbed together with the dust fall into the filter box 4. After passing through the filter box 4, the dust enters the sedimentation box 5. Since the connecting pipe 9 is directly inserted below the water surface in the sedimentation box 5, the dust enters the water and is absorbed by the water for a part, and the dust precipitates in the water, thereby reducing the dust content. The treated air is discharged into the atmosphere far from the production area through a pipeline, which not only reduces the air pollution but also avoids the dust floating in the working area and harming the physical health of the staff. The present utility model generates negative pressure at the dust suction nozzle 3 by means of the negative pressure pump 6 to absorb the dust generated at the feeding port 7 and the discharging port 8 of the crusher 2, and absorbs and treats the dust through the filter box 4 and the sedimentation box 5, and then discharges the treated air into the atmosphere, thereby avoiding a large amount of dust floating in the air, polluting the air environment, and avoiding harming the physical health of the staff.
[0015] A filter screen 10 for filtering large - particle raw materials is provided at the air outlet of the filter box 4. When attracting dust, some large - particle raw materials will be attracted along with the dust. When passing through the filter box 4, the large - particle raw materials will be blocked by the filter screen 10 and fall into the filter box 4, so that they can be taken out from the filter box 4 for reuse.
[0016] A cylindrical connection port is provided at the bottom of the filter box 4, and a storage tank 11 is connected to the connection port by a thread. The large - particle raw materials filtered and falling into the filter box 4 fall into the storage tank 11 through the connection port for storage. The storage tank 11 can be removed from the connection port by a thread, and then the stored large - particle raw materials can be reused, thus saving resources.
[0017] The opening structure of the dust - suction nozzle 3 is an arc - shaped structure corresponding to the edges of the feed inlet 7 and the discharge outlet 8. The opening of the dust - suction nozzle 3 is set as an arc - shaped structure corresponding to the feed inlet 7 and the discharge outlet 8, which is convenient for absorbing dust and does not affect the feeding and discharging of the crusher 2.
[0018] Working process:
[0019] The negative - pressure pump 6 makes the dust - suction nozzle 3 generate negative pressure to absorb the dust generated at the feed inlet 7 and the discharge outlet 8 of the crusher 2. The dust enters the filter box 4 through the connecting pipe 9, so that the large - particle raw materials absorbed along with the dust fall into the filter box 4. After passing through the filter box 4, the dust enters the sedimentation tank 5. Since the connecting pipe 9 is directly inserted below the water surface in the sedimentation tank 5, the dust enters the water and is absorbed by the water for a part, and the dust precipitates in the water, thus reducing the dust content. The treated air is discharged into the atmosphere far from the production area through the pipeline, which not only reduces air pollution but also avoids dust floating in the working area and endangering the health of the staff.
[0020] Finally, it should be noted that the above - mentioned preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail through the above - mentioned preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
