For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0027] See also Figures 1 to 3 A dust separation device for finely divided objects according to an embodiment of the utility model comprises: an inclined and elongated water trough member 100, the water trough member 100 is connected to a water circulation system, the water circulation system can drive water to circulate in and out of the water trough member 100 according to a preset liquid level, a feeding screw 200 is rotatably arranged in the water trough member 100 and extends along the length direction of the water trough member 100, the feeding screw 200 is connected to a rotary driver 300, a discharge port 400 is provided on the bottom wall of one end of the water trough member 100 that is inclined upward, the rotary driver 300 can drive the finely divided objects located in the water trough member 100 to climb along the lower end of the water trough member 100 to the upper end and be discharged from the discharge port 400.
[0028] When separating dust and impurities, the finely divided objects mixed with dust and impurities are placed in the water tank 100, and water is injected into the water tank 100 by using the water circulation system. The rotary driver 300 drives the feeding screw 200 to rotate so as to transport the finely divided objects from the lower end of the water tank 100 to the discharge port 400 at the upper end. In this process, the dust and impurities on the surface of the finely divided objects are washed and separated by water, and the water input into the water tank 100 by the water circulation system is discharged when it reaches a preset liquid level, thereby forming circulating water to better remove the dust and impurities on the surface of the finely divided objects. The dust separation device with the above structure can separate dust and impurities without losing the finely divided objects, thereby avoiding material waste.
[0029] In some embodiments of the utility model, the liquid level is higher than the height of the middle part of the length direction of the water tank 100, and the liquid level is lower than the height of the discharge port 400. It can be understood that when the liquid level is lower than the height of the discharge port 400, due to the inclined setting of the water tank 100, the fines put into the water tank 100 are accumulated to the lower end of the water tank 100 by gravity, and the feeding screw 200 drives the fines to climb along the lower end of the water tank 100 to the upper end of the discharge port 400 when rotating, so as to separate the water with dust and the fines. On the contrary, if the liquid level is higher than the height of the discharge port 400, a large amount of water is discharged together with the fines, which not only causes a large amount of water to be wasted, but also increases the possibility of dust and impurities reattaching to the surface of the fines. The liquid level is higher than the height of the middle part of the length direction of the water tank 100, which ensures that the water can clean the fines located in the middle and lower part of the water tank 100.
[0030] See also Figure 2 In some embodiments of the present invention, the water tank 100 includes a long strip bottom plate 110, the cross-section of the bottom plate 110 is in an arc shape, and the two side edges of the bottom plate 110 are respectively extended upward to form a first side plate 120 and a second side plate 130, and the upper and lower ends of the bottom plate 110 are respectively provided with an upper end plate 140 and a lower end plate 150, see Figure 3The feeding screw 200 includes a rotating shaft 210 that is movably provided on the upper end plate 140 and the lower end plate 150. The rotating driver 300 is connected to one end of the rotating shaft 210. The rotating shaft 210 is provided with a spiral feeding piece 220 extending along its length direction. The spiral feeding piece 220 is close to the inner peripheral wall of the bottom plate 110. It can be understood that the bottom plate 110, the first side plate 120, the second side plate 130, the upper end plate 140 and the lower end plate 150 together constitute the water tank part 100. In this embodiment, the bottom plate 110, the first side plate 120, the second side plate 130, the upper end plate 140 and the lower end plate 150 are an integrated sheet metal structure, which simplifies the production and processing procedures and reduces costs. Since the spiral feeding piece 220 is close to the inner circumferential wall of the bottom plate 110 , that is, the gap between the outer circumferential edge of the spiral feeding piece 220 and the inner circumferential wall of the bottom plate 110 is very small, the fine particles are prevented from moving toward the upper end of the bottom plate 110 .
[0031] See also Figure 1 In some embodiments of the utility model, the water circulation system includes a water collection tank 510 disposed on the outer side of the first side plate 120, the first side plate 120 is provided with a notch groove 121 connected to the water collection tank 510, the bottom of the notch groove 121 extends in the horizontal direction to limit the liquid level, the water collection tank 510 is connected to a water storage tank 530 through a first pipe 520, the water storage tank 530 is connected to a water pump, and the water pump is connected to a water delivery pipeline 540 that drives water back to the water tank 100. It can be understood that the water delivery pipeline 540 inputs water into the water tank 100, and when the water reaches the liquid level, the excess water enters the water collection tank 510 and returns to the water storage tank 530, and is supplied again by the water pump. In some embodiments, in order to ensure the cleanliness of the circulating water, a filter component is also provided in the water storage tank 530.
[0032] See also Figure 1 and Figure 2In some embodiments of the utility model, the lower end plate 150 is provided with a first axial hole 151 for the rotating shaft 210 to pass through, and the upper end plate 140 is provided with a second axial hole 141 for the rotating shaft 210 to pass through. There is a gap between the first axial hole 151 and the rotating shaft 210, and between the second axial hole 141 and the rotating shaft 210. A first reflux component 600 is provided on the outer side of the lower end of the trough part 100. The first reflux component 600 can receive water overflowing from the gap between the first axial hole 151 and the rotating shaft 210 and re-input the water into the trough part 100. It can be understood that the two ends of the rotating shaft 210 are passed through the upper end plate 140 and the lower end plate 150. During the rotation of the rotating shaft 210, the water in the trough part 100 can overflow from the gap between the rotating shaft 210 and the first axial hole 151, causing sewage to spill and pollute the ground environment. The first reflux component 600 can allow the overflowed water to be re-input into the trough part 100, and there is no need to set a seal between the rotating shaft 210 and the first axial hole 151 to avoid the above situation.
[0033] See also Figure 1 In some embodiments of the present invention, the first reflux assembly 600 includes a first enclosure 610 fixed to the outer wall of the lower end plate 150 and for the rotating shaft 210 to movably pass through, and a first water collecting tank is defined between the first enclosure 610 and the lower end plate 150, and the lower end of the first water collecting tank is connected to the water storage tank 530 through a second pipe 620. Specifically, the bottom wall of the first water collecting tank is lower than the lowest height of the first shaft hole 151, and during the rotation of the rotating shaft 210, the water in the water tank 100 can overflow from the gap between the rotating shaft 210 and the first shaft hole 151, and the overflowed water enters the first water collecting tank and flows back to the water storage tank 530 through the second pipe 620.
[0034] See also Figure 1 and Figure 2 In some embodiments of the present invention, a second reflux assembly 700 is provided on the outer side of the upper end of the water tank 100, and the second reflux assembly 700 can receive water overflowing from the gap between the second shaft hole 141 and the rotating shaft 210 and re-input the water into the water tank 100. It can be understood that the two ends of the rotating shaft 210 are penetrated through the upper end plate 140 and the lower end plate 150. During the rotation of the rotating shaft 210, the water in the water tank 100 will splash out from the gap between the rotating shaft 210 and the second shaft hole 141, causing sewage to spill and pollute the ground environment. The second reflux assembly 700 can allow the overflowed water to be re-input into the water tank 100, and there is no need to set a seal between the rotating shaft 210 and the second shaft hole 141, so as to avoid the above situation.
[0035] See also Figure 1In some embodiments of the present invention, the second reflux assembly 700 includes a second enclosing plate 710 fixed to the outer side wall of the upper end plate 140 and for the rotating shaft 210 to movably pass through, and a second water collecting tank is defined between the second enclosing plate 710 and the upper end plate 140, and the lower end of the second water collecting tank is connected to the water collecting tank 510 or the water storage tank 530 through a third pipe 720. Specifically, the bottom wall of the second water collecting tank is lower than the lowest height of the second shaft hole 141, and during the rotation of the rotating shaft 210, the water in the water tank 100 can overflow from the gap between the rotating shaft 210 and the second shaft hole 141, and the overflowed water enters the second water collecting tank and flows back to the water collecting tank 510 through the third pipe 720, and then is collected back to the water storage tank 530.
[0036] In some embodiments of the utility model, in order to collect fine matter and separate a small amount of water, a container for receiving the fine matter (not shown in the figure) is provided below the discharge port 400, and the container is provided with a mesh screen (not shown in the figure) for dividing the internal space thereof into an upper chamber and a lower chamber, the upper chamber and the lower chamber are used for accommodating the fine matter and water, respectively, and the lower chamber is connected to the water storage tank 530 via a fourth pipe (not shown in the figure).
[0037] See also Figure 1 In some embodiments of the utility model, a drop pipe 800 is arranged just above the lower end of the water tank 100, and the drop pipe 800 is used to convey the fine pieces mixed with dust and impurities downward toward the water tank 100, and the water delivery pipe 540 is connected to the side of the drop pipe 800 to communicate with the internal channel of the drop pipe 800, and the end of the water delivery pipe 540 is provided with a high-pressure nozzle extending horizontally into the internal channel of the drop pipe 800. It can be understood that when it is necessary to clean the fine pieces, the fine pieces are continuously poured into the drop pipe 800 at a certain flow rate, and the fine pieces discharged from the lower end of the drop pipe 800 fall into the water tank 100. In this process, the water pump supplies water to the water delivery pipe 540, and the high-pressure nozzle sprays water to clean the fallen fine pieces, which is conducive to improving the separation efficiency of dust and impurities.
