Description

Technical Field

[0001] This utility model relates to the field of dust suppression technology for crushers, and in particular to an auxiliary dust suppression structure at the outlet of a crusher. Background Technology

[0002] A crusher is a mechanical device that uses mechanical force to break large materials into smaller particles. It is widely used in industries such as mining, metallurgy, building materials, chemicals, and environmental protection. Its core function is to change the particle size of materials through impact, extrusion, shearing, and grinding to meet the needs of subsequent material processing.

[0003] During the crushing process, crushers often generate a lot of dust. The dust is discharged from the crusher outlet along with the crushed material, which can pollute the surrounding environment. Traditionally, dust suppression at the crusher outlet mainly uses spraying. However, spraying causes water accumulation in the surrounding environment and the wastewater that has absorbed the dust can cause secondary pollution, requiring extra manpower for cleaning.

[0004] Therefore, the traditional dust suppression method for crusher outlets mainly uses spraying. However, spraying causes water accumulation in the surrounding environment and the wastewater that has absorbed dust can cause secondary pollution, requiring extra manpower for cleaning. A dust suppression auxiliary structure for crusher outlets can be designed to collect and reuse the wastewater generated after spraying, effectively preventing secondary pollution and reusing some water resources, which is more convenient and environmentally friendly. Utility Model Content

[0005] To overcome the problem that traditional dust suppression methods at the crusher outlet mainly use spraying, spraying can cause water accumulation in the surrounding environment and wastewater that has absorbed dust, resulting in secondary pollution and requiring additional manpower for cleaning.

[0006] The technical solution of this utility model is as follows: an auxiliary dust suppression structure for a crusher outlet, comprising a crusher body, a protective enclosure, a filter plate, an installation pipe, an atomizing nozzle, a sedimentation tank, a transfer box, a filter, and a conveying assembly. The protective enclosure is fixedly installed around the outlet of the crusher body. Two sets of installation pipes are fixedly installed at the upper end of the protective enclosure, one set of installation pipes is close to the outlet of the crusher body, and the other set of installation pipes is close to the outlet of the protective enclosure. Multiple sets of atomizing nozzles are connected through the lower end of the installation pipes. A filter plate is fixedly installed inside the protective enclosure, and the filter plate is inclined. The sedimentation tank is located on one side of the protective enclosure, and the transfer box is located on one side of the sedimentation tank. The filter is fixedly installed above the transfer box, and the conveying assembly is located between the transfer box and the installation pipe.

[0007] Preferably, by setting up a transfer box, clean water can be supplied to the installation pipe through the conveying assembly. By setting up a protective enclosure, the perimeter of the crusher body outlet can be blocked, thereby limiting the generated dust and reducing its spread. By setting up two sets of installation pipes to supply clean water to the atomizing nozzles, the atomizing nozzles spray water mist to suppress dust. The water mist sprayed by the atomizing nozzles is confined inside the protective enclosure. The water mist sprayed by the atomizing nozzles below the installation pipe near the crusher body outlet absorbs the large amount of dust emitted from the outlet. The installation pipe near the outlet of the protective enclosure... The water mist sprayed from the atomizing nozzles below can adsorb the remaining dust and prevent it from escaping from the exit of the protective enclosure. By setting up filter plates, the crushed material being conveyed can be filtered, allowing the material to be discharged from the protective enclosure along the inclined filter plates. Wastewater will pass through the filter plates and fall into the interior of the protective enclosure, then enter the sedimentation tank for sedimentation, initially separating water and dust. It is then transported to the filter for further filtration and returned to the transfer box for reuse. The sedimentation tank can effectively reduce the filtration pressure of the filter, reduce the frequency of filter element replacement, and reduce costs.

[0008] Preferably, a first guide plate is fixedly installed inside the protective enclosure, located below the filter plate. A drain outlet is provided on the side wall of the protective enclosure, located at the bottom of the slope of the first guide plate, and a sedimentation tank is located below the drain outlet.

[0009] Preferably, the sedimentation tank has multiple sets of partitions fixedly installed inside, the partitions are arranged linearly and evenly, and the side walls of the partitions have multiple sets of connecting holes.

[0010] Preferably, a second guide plate is fixedly installed on the upper part of the inner bottom surface of the sedimentation tank, and multiple sets of sewage pipes are connected through the lower end of the sedimentation tank. The multiple sets of sewage pipes are located between the multiple sets of partitions and the inner wall of the sedimentation tank, and a sewage valve is provided at the connection between the sewage pipes and the sedimentation tank.

[0011] Preferably, the upper end of the transfer box is connected to a clean water interface, and a water level bar is provided on one side of the transfer box.

[0012] Preferably, the upper end of the filter is connected to a first connecting pipe, which is connected to the sedimentation tank, and the lower end of the filter is connected to a second connecting pipe, which is connected to the transfer box.

[0013] Preferably, the conveying assembly includes a water pump, a pumping pipe, and a conveying pipe. The water pump is fixedly installed at the top of the transfer box, the pumping pipe is connected to the input end of the water pump, the inlet of the pumping pipe is located inside the transfer box, the conveying pipe is connected to the output end of the water pump, and the conveying pipe is connected to the installation pipe.

[0014] The beneficial effects of this utility model are:

[0015] When the crusher body discharges material, a protective enclosure can be used to contain the outer perimeter of the crusher body outlet, thereby limiting the generated dust and reducing its spread. Simultaneously, the sprayed water mist can be confined inside the protective enclosure. Water mist sprayed from atomizing nozzles below the installation pipe near the crusher body outlet absorbs a large amount of dust escaping from the outlet. Water mist from atomizing nozzles below the installation pipe near the protective enclosure outlet absorbs the remaining dust, preventing it from escaping from the protective enclosure outlet. Furthermore, the crushed material is filtered through a filter plate, allowing it to flow along the inclined filter plate and exit through the protective enclosure. Wastewater passes through the filter plate and is guided by the first guide plate to the drain outlet before entering the sedimentation tank for sedimentation and recycling. This effectively prevents secondary pollution and allows for the reuse of some water resources, making it more convenient and environmentally friendly. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 and Figure 3This utility model provides an embodiment of an auxiliary dust suppression structure for a crusher outlet, comprising a crusher body 1, a protective enclosure 2, a filter plate 3, an installation pipe 4, an atomizing nozzle 401, a sedimentation tank 5, a transfer box 6, a filter 7, and a conveying assembly. The protective enclosure 2 is fixedly installed around the outlet of the crusher body 1. Two sets of installation pipes 4 are fixedly installed at the upper end of the protective enclosure 2, one set of installation pipes 4 being close to the outlet of the crusher body 1 and the other set being close to the outlet of the protective enclosure 2. Multiple sets of atomizing nozzles 401 are connected through the lower end of the installation pipes 4. The filter plate 3 is fixedly installed inside the protective enclosure 2, and the filter plate 3 is inclined. The sedimentation tank 5 is located on one side of the protective enclosure 2, and the transfer box 6 is located on one side of the sedimentation tank 5. The filter 7 is fixedly installed above the transfer box 6. The conveying assembly is located between the transfer box 6 and the installation pipe 4. By setting up the transfer box 6, clean water can be provided to the installation pipe 4 through the conveying assembly. By setting up the protective enclosure 2, the perimeter of the outlet of the crusher body 1 can be enclosed, thereby suppressing the generated dust. To limit and reduce dust dispersion, two sets of installation pipes 4 are installed to supply clean water to the atomizing nozzles 401. The atomizing nozzles 401 spray water mist to suppress dust. The water mist sprayed by the atomizing nozzles 401 is confined inside the protective enclosure 2. The water mist sprayed by the atomizing nozzles 401 below the installation pipe 4 near the outlet of the crusher body 1 adsorbs a large amount of dust emitted from the outlet. The water mist sprayed by the atomizing nozzles 401 below the installation pipe 4 near the outlet of the protective enclosure 2 can adsorb the remaining dust, while preventing dust from escaping from the outlet of the protective enclosure 2. The filter plate 3 is installed to filter the conveyed crushed material, allowing the material to be discharged from the protective enclosure 2 along the inclined filter plate 3. The wastewater will pass through the filter plate 3 and fall into the interior of the protective enclosure 2 and then enter the sedimentation tank 5 for sedimentation, initially separating water and dust. Then it is conveyed to the filter 7 for filtration and sent back to the transfer box 6 for reuse. The sedimentation tank 5 can effectively reduce the filtration pressure of the filter 7, reduce the frequency of filter element replacement of the filter 7, and reduce costs.

[0023] Please see Figure 1 and Figure 2 In this embodiment, a first guide plate 201 is fixedly installed inside the protective enclosure 2. The first guide plate 201 is located below the filter plate 3. A drain outlet 202 is opened on the side wall of the protective enclosure 2. The drain outlet 202 is located at the bottom of the slope of the first guide plate 201. The sedimentation tank 5 is located below the drain outlet 202. By setting the first guide plate 201, the sewage passing through the filter plate 3 can be guided, and by setting the drain outlet 202, the sewage can be transported into the sedimentation tank 5 for sedimentation.

[0024] Please see Figure 3 and Figure 4In this embodiment, multiple sets of partitions 501 are fixedly installed inside the sedimentation tank 5. These partitions 501 are arranged linearly and evenly, and multiple sets of connecting holes 502 are formed on the sidewalls of the partitions 501. By setting the partitions 501, multiple sedimentation spaces can be divided inside the sedimentation tank 5, achieving multi-stage sedimentation, reducing the impact of water inflow from the drain outlet 202 on sedimentation, and improving the sedimentation effect. The connecting holes 502 allow communication between the spaces separated by the partitions 501 within the sedimentation tank 5. A second guide plate 503 is fixedly installed at the upper end of the bottom surface inside the sedimentation tank 5. Multiple sets of sewage pipes 504 are connected through the end of the sedimentation tank 5. These sewage pipes 504 are located between multiple sets of partitions 501 and the inner wall of the sedimentation tank 5. A sewage valve 505 is installed at the connection point between the sewage pipe 504 and the sedimentation tank 5. A second guide plate 503 guides the sludge settled in the sedimentation tank 5 to the sewage pipe 504, facilitating the discharge of the settled sludge. The sewage pipe 504 can be controlled by the sewage valve 505. A clean water interface 601 is connected through the upper end of the transfer box 6, and a water level bar 602 is installed on one side of the transfer box 6. The clean water interface 601 allows connection to an external water source to supply clean water to the transfer tank 6. The water level bar 602 allows for monitoring and confirmation of the water content within the transfer tank 6. A first connecting pipe 701 is connected to the upper end of the filter 7, which is connected to the sedimentation tank 5. A second connecting pipe 702 is connected to the lower end of the filter 7, which is connected to the transfer tank 6. The first connecting pipe 701 allows the recycled water from the multi-stage sedimentation in the sedimentation tank 5 to be supplied to the filter 7. The second connecting pipe 702 allows the recycled water to be supplied to the transfer tank 6. The recycled water filtered by filter 7 is transported to transfer tank 6. The transport assembly includes a water pump 801, a pumping pipe 802, and a delivery pipe 803. The water pump 801 is fixedly installed at the upper end of the transfer tank 6. The pumping pipe 802 is connected to the input end of the water pump 801, and the inlet of the pumping pipe 802 is located inside the transfer tank 6. The delivery pipe 803 is connected to the output end of the water pump 801 and is connected to the installation pipe 4. By setting the water pump 801 to draw clean water from the transfer tank 6 through the pumping pipe 802, pressurize it, and then transport it to the installation pipe 4 through the delivery pipe 803.

[0025] During operation, water pump 801 draws clean water from transfer box 6 through water pipe 802, pressurizes it and delivers it to installation pipe 4 through conveying pipe 803, and then uses installation pipe 4 to deliver clean water to each atomizing nozzle 401 to spray water mist to reduce dust at the outlet of crusher body 1.

[0026] The protective enclosure 2 can be used to enclose the perimeter of the outlet of the crusher body 1, thereby limiting the generated dust and reducing its spread. At the same time, the sprayed water mist can be confined inside the protective enclosure 2. The water mist sprayed by the atomizing nozzle 401 below the installation pipe 4 near the outlet of the crusher body 1 can absorb the large amount of dust emitted from the outlet. The water mist sprayed by the atomizing nozzle 401 below the installation pipe 4 near the outlet of the protective enclosure 2 can absorb the remaining dust and prevent the dust from escaping from the outlet of the protective enclosure 2.

[0027] The filter plate 3 can be used to filter the crushed material being conveyed, so that the material is discharged from the protective enclosure 2 along the inclined filter plate 3. The sewage will pass through the filter plate 3 and be guided by the first guide plate 201 to the drain outlet 202 for discharge and then enter the sedimentation tank 5 for sedimentation.

[0028] The partition 501 can be used to divide the interior of the sedimentation tank 5 into multiple sedimentation spaces. The sewage entering the sedimentation tank 5 will accumulate and settle in each sedimentation space one by one. After reaching the height of the connecting hole 502, it will enter the next sedimentation space. Multi-stage sedimentation can effectively provide the sedimentation effect. The settled recycled water enters the filter 7 through the first connecting pipe 701 and is filtered again. Finally, it enters the transfer tank 6 through the second connecting pipe 702 to complete the recycling.

[0029] After the sedimentation tank 5 has been working for a period of time, the drain valve 505 can be used to control the drain pipe 504 to discharge the sludge and dust settled at the bottom of the sedimentation tank 5.

[0030] Through the above steps, the protective enclosure 2 can enclose the perimeter of the crusher body 1 outlet, thereby limiting the generated dust and reducing its spread. Simultaneously, it can confine the sprayed water mist inside the protective enclosure 2. The water mist sprayed from the atomizing nozzle 401 below the installation pipe 4 near the outlet of the crusher body 1 absorbs a large amount of dust emitted from the outlet. The water mist sprayed from the atomizing nozzle 401 below the installation pipe 4 near the outlet of the protective enclosure 2 can absorb the remaining dust, preventing it from escaping from the outlet of the protective enclosure 2. The dust then passes through the filter plate... 3 can filter the crushed material after it is conveyed out, so that the material is discharged from the protective enclosure 2 along the inclined filter plate 3. The sewage will pass through the filter plate 3 and be guided to the drain outlet 202 by the first guide plate 201 and then enter the sedimentation tank 5 for sedimentation and recycling. This effectively prevents secondary pollution and can also reuse some water resources, which is more convenient and environmentally friendly. This solves the problem that the dust suppression at the outlet of the traditional crusher is mainly achieved by spraying dust suppression. However, spraying dust suppression causes water accumulation in the surrounding environment and the sewage that has absorbed dust will cause secondary pollution, requiring additional manpower for cleaning.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
