Description

Technical Field

[0001] The present application relates to the technical field of ore electrostatic separation equipment, and in particular to an electrostatic separator screening device. Background Art

[0002] After the ore is mined, it needs to be processed by jaw crusher to form crushed ore of different particle sizes. For some relatively broken slag, operators need to screen it, that is, to divide the slag into magnetic residue and non-magnetic waste (or waste with insufficient magnetism) to improve the utilization efficiency of the ore. The above-mentioned magnetic residue is called "useful material", and the waste with no magnetism or insufficient magnetism is called "useless material". The electrostatic screening equipment can screen the useful and useless materials of the slag.

[0003] Generally speaking, the basic principle of electrostatic screening equipment is to use water flow to dilute slag to form a fluid mixture, and then place the mixture on an inclined conveyor belt, and set a force field around the conveyor belt that can generate gravity for the useful material, so that the useful material overcomes gravity and moves upward along the conveyor belt until the useful material moves to the lower surface of the conveyor belt. The gravity decreases with the increase of distance, and then the useful material on the conveyor belt is washed by water flow to make it fall off the conveyor belt, and then the useful material is collected. The useless material slides down along the conveyor belt with the fluid mixture because it does not receive gravity or the gravity is insufficient, thus completing the screening process.

[0004] In the above-mentioned slag electrostatic separation process, a large amount of flowing water is required, which increases the consumption of water resources and also increases the processing cost of slag electrostatic separation. Utility Model Content

[0005] In order to reduce the amount of water required for slag electrostatic separation, the present application provides an electrostatic separator screening device.

[0006] The present application provides an electrostatic separator screening device, which adopts the following technical solution:

[0007] An electric separator screening device comprises a machine body, on which an inclined conveyor belt is arranged, on which a nozzle 1 for spraying a dilution water flow is arranged, on which a nozzle 2 for spraying a flushing water flow to the conveyor belt is arranged, on which a water storage tank is arranged, and the water storage tank is used to receive the water flow falling from the conveyor belt, and the water storage tank and the nozzle 1 and the nozzle 2 are connected to each other. The device also comprises a pumping mechanism, and the pumping mechanism is used to supply the water in the water storage tank to the nozzle 1 and the nozzle 2. A filtering mechanism is arranged on the water storage tank, and the filtering mechanism is used to filter useful materials.

[0008] Through the above technical scheme, the water flow sprayed from nozzle one and nozzle two, as well as the useful materials flushed down by the water flow sprayed from nozzle two, can flow into the water tank along the conveyor belt, be filtered by the filtering mechanism, and start the pumping mechanism. The water flow can be pumped back to nozzle one and nozzle two by the pumping mechanism to dilute and flush the slag.

[0009] During the above operation, the used water flows into the water storage tank and is re-pumped to nozzles one and two, so that the water can be reused, thereby effectively reducing the amount of water required for slag electrostatic separation, thereby reducing the consumption of water resources and reducing the processing cost of slag electrostatic separation.

[0010] In a preferred example, the utility model can be further configured as follows: the pumping mechanism includes a water pump and a pipe, one end of the pipe is connected to the water storage tank, and the other end is connected to the nozzle 1 and the nozzle 2, and the water pump is installed on the pipe.

[0011] Through the above technical solution, the operator starts the water pump, and the water pump pumps the water in the water tank to the first and second nozzles through the pipeline, completing the recycling of water flow, thereby reducing the consumption of water resources.

[0012] In a preferred example, the utility model can be further configured as follows: the filtering mechanism includes a filter screen, and the filter screen is arranged on the water tank.

[0013] Through the above technical solution, when useful materials flow into the water tank with the water flow, the useful materials can be retained on the filter net due to the obstruction of the filter net, while the water flow can enter the water tank, thereby realizing the screening process of the water flow and the useful materials.

[0014] In a preferred example, the utility model can be further configured as follows: a positioning frame 1 and a positioning frame 2 are provided on the water tank, the filter net is provided between the positioning frame 1 and the positioning frame 2, the positioning frame 2 is hinged to the water tank, and the positioning frame 1 and the positioning frame 2 are connected by a connecting piece.

[0015] Through the above technical solution, the filter is arranged between the positioning frame 1 and the positioning frame 2, and is clamped and fixed by the positioning frame 1 and the positioning frame 2, so as to play the filtering role of the filter. In addition, the operator can replace the filter by releasing the connection between the positioning frame 1 and the positioning frame 2 by the connecting piece.

[0016] In a preferred example, the utility model can be further configured as follows: the connecting member includes a bolt 1, the bolt 1 is penetrated on the positioning frame 1, and the bolt 1 is threadedly connected to the positioning frame 2.

[0017] With the above technical solution, the operator releases the connection between the positioning frame 1 and the positioning frame 2 by tightening the bolts, so as to remove the filter from between the positioning frame 1 and the positioning frame 2 and then install a new filter.

[0018] In a preferred example, the utility model can be further configured as follows: a connecting rod is provided on the positioning frame, a buckle is rotatably installed on the water storage tank, and the buckle can be rotatably buckled on the connecting rod.

[0019] Through the above technical solution, when the operator rotates the positioning frame one to place the filter cover on the water tank, the operator drives the buckle ring to flip upward by rotating the buckle ring so that the buckle ring is buckled on the connecting rod. At this time, the buckle ring has an obstructing effect on the connecting rod and the positioning frame one, thereby reducing the possibility of the positioning frame one rotating upward due to the vibration of the machine body.

[0020] In a preferred example, the utility model can be further configured as follows: a sleeve is slidably sleeved on the nozzle pipe 1, and a plurality of spray holes for spraying water are opened on the nozzle pipe 1.

[0021] Through the above technical solution, when there is less slag falling on the conveyor belt, the operator shortens the exposed length of nozzle one by sliding the sleeve to reduce the number of exposed spray holes, thereby reducing the water flow sprayed from nozzle one per unit time, thereby further reducing the consumption of water resources.

[0022] On the contrary, when there is a lot of slag falling on the conveyor belt, the operator increases the exposed length of the nozzle 1 by sliding the sleeve to increase the number of exposed spray holes to meet the dilution demand of the slag.

[0023] In a preferred example, the utility model can be further configured as follows: a through hole is opened on the sleeve, a second bolt is inserted into the through hole, a plurality of connecting holes are opened on the first nozzle, the plurality of connecting holes and the plurality of nozzles are arranged in a one-to-one correspondence, and the second bolt is threadedly matched with the inner wall of the connecting hole.

[0024] Through the above technical solution, after the operator completes the adjustment of the exposed length of the nozzle one, by turning the bolt two, the bolt two is threadedly connected to the inner wall of the corresponding connecting hole. At this time, under the obstruction of the bolt two, the possibility of changes in the number of exposed nozzle holes is reduced.

[0025] In summary, the utility model includes the following beneficial technical effects:

[0026] 1. After the water on the conveyor belt falls into the water tank, the operator starts the water pump to supply the water in the water tank to the nozzle 1 and nozzle 2, so that the water can be reused, thereby effectively reducing the amount of water required for slag electrostatic separation and reducing the processing cost of slag electrostatic separation;

[0027] 2. The filter is detachably mounted on the water tank, so that the operator can replace the filter and maintain the filtering effect of the filter;

[0028] 3. The operator changes the exposed length of the nozzle one by sliding the sleeve to change the number of exposed spray holes, thereby being able to control the water flow sprayed from the nozzle one per unit time, thereby being able to control the water flow according to actual needs, thereby further refining the control of the water flow.

[0039] See attached Figure 1 and attached Figure 2 As shown, a nozzle 11 is installed on the material hopper 7, and the nozzle 11 is arranged just above the upper surface of the conveyor belt 2. The nozzle 11 is used to spray dilution water flow to the upper surface of the conveyor belt 2 to dilute the slag. The nozzle 11 is arranged horizontally, and a plurality of spray holes 111 are opened on the nozzle 11, each of which is arranged downward, and the plurality of spray holes 111 are evenly distributed along the length direction of the nozzle 11. A nozzle 2 12 is installed on the machine body 1, and the nozzle 2 12 can spray a flushing water flow to flush the useful materials on the conveyor belt 2.

[0040] See attached Figure 1 and attached Figure 2 As shown, a water storage tank 3 is installed on the machine body 1, the top of the water storage tank 3 is open, and the water storage tank 3 is located directly below the lowest point of the conveyor belt 2, so as to receive the water flow falling from the conveyor belt 2 and the useful materials mixed in the water flow. The water storage tank 3 and the nozzle 1 11 and the nozzle 2 12 are connected to each other.

[0041] See attached Figure 1 and attached Figure 2 As shown, a pumping mechanism 4 is provided on the back of the machine body 1 for supplying water in the water storage tank 3 to the nozzle 1 11 and the nozzle 2 12.

[0042] The water flow on the conveyor belt 2 can fall into the water tank 3, and after accumulating to a certain amount of water, the operator starts the water pump 41 to supply the water in the water tank 3 to the nozzle 11 and the nozzle 2 12.
