[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figures 1-4 Shown:

[0028] Example 1:

[0029] A continuous collection device for flotation tailings slurry includes:

[0030] Flotation tank 1;

[0031] Water tank 2 is located on one side of flotation tank 1;

[0032] Water supply component 3 is installed at the connection between flotation tank 1 and water tank 2;

[0033] The recovery component 4 includes a second recovery pipe 403 that is inserted and connected to one side of the flotation tank 1. A filter element 5 is provided on one side of the second recovery pipe 403, and a first recovery pipe 401 is provided on one side of the filter element 5. The first recovery pipe 401 is inserted and connected to the top of the water tank 2, and a third valve 402 is provided in the middle of the first recovery pipe 401.

[0034] It should be noted that an inlet pipe is provided on one side of the water tank 2, which is used to replenish the liquid inside the water tank 2 during use; the second recovery pipe 403 is located in the middle of the flotation tank 1. During use, after the coal layer at the top of the flotation tank 1 is discharged, the third valve 402 is opened to allow the liquid at the top of the flotation tank 1 to enter the water tank 2 and recover the liquid between the coal layer and the impurity layer, thereby reducing the waste of liquid.

[0035] Specifically, a feed pipe 101 is provided at the top of the flotation tank 1, a waste outlet pipe 104 is provided at the bottom of the flotation tank 1, a second valve 105 is provided at the bottom of the waste outlet pipe 104, a coal outlet pipe 103 is provided on the other side of the flotation tank 1, and a first valve 102 is provided in the middle of the coal outlet pipe 103.

[0036] It should be noted that the first valve 102 and the second valve 105 are existing electric gate valves, which are gate valves driven by an electric actuator during use and are mainly used to control the flow of fluid in the pipeline or to regulate the flow rate.

[0037] Furthermore, during use, the material is first fed into the flotation tank 1 through the feed pipe 101, and then the liquid inside the water tank 2 is fed into the flotation tank 1 through the water supply assembly 3, so that the water level is higher than the height of the coal outlet pipe 103. After settling, the coal and impurities in the material are separated. The coal floats to the top to form a coal layer, and the impurities sink to form an impurity layer. After separation, the first valve 102 is opened, so that the coal layer is discharged from the flotation tank 1 through the coal outlet pipe 103. When the coal is discharged, the third valve 402 is opened, so that the liquid layer at the bottom of the coal layer is fed into the water tank 2 through the first recovery pipe 401 and the second recovery pipe 403, and part of the liquid is recovered. Finally, the second valve 105 is opened to discharge the impurity layer inside the flotation tank 1.

[0038] Specifically, water conveyance component 3 includes:

[0039] The water pump pipe 301 is inserted and connected to the top of the water tank 2;

[0040] Water pump 302 is installed on top of water tank 2, and water pump pipe 301 is installed at the input end of water pump 302;

[0041] Water inlet pipe 303 is located on one side of flotation tank 1 and at the output end of water pump 302.

[0042] It should be noted that the bottom end of the pumping pipe 301 is inserted into the top of the water tank 2, and the bottom end of the pumping pipe 301 is close to the inner wall of the bottom of the water tank 2, with a distance of ten centimeters between them. The pump 302 is an existing centrifugal pump. Its working principle is to generate centrifugal force by rotating the impeller at high speed, which draws the liquid from the center and throws it radially out, thereby converting mechanical energy into the kinetic and pressure energy of the liquid. The specific process is as follows: the motor drives the pump shaft to rotate the impeller. Under the action of centrifugal force, the liquid between the impeller blades is thrown towards the inner wall of the pump casing, forming a high-pressure zone and being discharged from the outlet. At the same time, a low-pressure zone is formed in the center of the impeller, so that the liquid is continuously drawn in from the suction pipe, realizing continuous transportation, thereby realizing the input of the liquid inside the water tank 2 into the flotation tank 1.

[0043] Example 2:

[0044] Filter element 5 is used in the continuous collection device for flotation tailings slurry in Example 1;

[0045] Specifically, the filter element 5 includes a cleaning box 504 located on the opposite side of the first recovery pipe 401 and the second recovery pipe 403. The bottom of the cleaning box 504 is provided with a door 508, and a filter screen 506 is inserted and connected to the inner wall of one side of the cleaning box 504.

[0046] It should be noted that a sealing ring is provided at the connection between the cleaning box 504 and the box door 508. This ring is used to seal the connection between the cleaning box 504 and the box door 508 during use, preventing liquid from overflowing from the connection between the cleaning box 504 and the box door 508. The filter screen 506 is fixedly connected to one side of the cleaning box 504. The filter screen 506 has holes with a diameter of 100 to 50 mesh. This screen is used to block impurities during use, preventing impurities from entering the water tank 2.

[0047] Specifically, a sliding block 502 is inserted inside the cleaning box 504, a cleaning brush 503 is fixedly connected to one side of the sliding block 502, an electric push rod 501 is fixedly connected to the top of the cleaning box 504, a connecting rod 505 is fixedly connected to the output end of the electric push rod 501, the connecting rod 505 is inserted into the middle of the sliding block 502, a waste guide block 507 is fixedly connected to the bottom end of the connecting rod 505, and the waste guide block 507 is fixedly connected to the top of the box door 508.

[0048] It should be noted that the electric actuator 501 is an existing device for moving objects linearly. Its working principle is that a motor drives a worm gear or gear transmission mechanism to rotate a lead screw or nut, thereby pushing the actuator to perform reciprocating linear motion, which in turn moves the connecting rod 505 at the output end of the electric actuator 501. A sealing ring is provided at the connection between the output end of the electric actuator 501 and the cleaning box 504. During use, this seal is used to seal the connection between the electric actuator 501 and the cleaning box 504 to prevent liquid from overflowing from the connection. The cleaning brush 503 is used to clean impurities on the filter screen 506. The sliding block 502 is fixedly connected to the connecting rod 505. During use, the sliding block 502 drives the connecting rod 505 to connect.

[0049] Furthermore, during use, the electric push rod 501 drives the connecting rod 505 to move, and the connecting rod 505 drives the sliding block 502 and the door 508 to move. The sliding block 502 drives the cleaning brush 503 to clean the impurities on the filter screen 506. At the same time, the sliding block 502 drives the door 508 to open and remove the cleaned impurities from the cleaning box 504.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
