Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a tailings slurry filtering device. Background Art

[0002] One of the products of sorting operations in mineral processing, the part with the lowest content of useful target components is called tailings. Under the current technical and economic conditions, it is no longer suitable for further sorting. However, with the development of production science and technology, useful target components may have economic value for further recycling. Tailings are not completely useless waste. They often contain components that can be used for other purposes. They can be comprehensively utilized to achieve zero waste discharge, which is necessary for the full utilization of mineral resources and the protection of the ecological environment. At present, the slurry of tailings needs to be filtered, and when the existing filtering device filters the tailings, the filtered tailings accumulate on the surface of the filter for a long time, causing the filter to be blocked, affecting the subsequent normal filtration of the tailings slurry. The filtered tailings slurry needs to be collected from time to time and then filtered. The filtration efficiency is low, which increases the time for slurry filtration and affects the recovery of tailings. Utility Model Content

[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology and to propose a tailings slurry filtering device.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] The sieve is fixed on the top of described sieve body, and the sieve is fixed on the top of described sieve body, and the sieve is fixed on the sieve body inner wall, and the sieve is fixed on the sieve body inner wall.

[0006] Preferably, the guide plate is arranged in a "funnel" shape, the middle of the separation cylinder is connected to the opening at the bottom of the guide plate, and the stirring rod is vertically arranged to penetrate the middle of the separation cylinder and the guide plate.

[0007] Preferably, eight separation sheets and eight partition plates are provided, and the separation sheets and the partition plates are arranged in a circular shape around the stirring rod and the middle of the separation cylinder respectively.

[0008] Preferably, the separation sheets are just in close contact with the bottom end of the partition plate, and the stirring blades are just arranged at the bottom end of the separation cylinder.

[0009] Preferably, the middle right opening of the inner cylinder is provided with a discharge port which is in communication with the inside of the discharge plate. The discharge port is arranged just on the right side of the upper surface of the filter screen, and the baffle is just embedded in the leftmost side of the discharge port.

[0010] Preferably, three scrapers are provided at the bottom of the stirring rod, and the scrapers are arranged in a circular shape around the middle of the stirring rod, and the bottom end and outer side of the scraper are respectively in close contact with the upper surface of the filter screen and the inner wall of the inner cylinder.

[0011] 1. When the tailings slurry falls on the filter screen, the impurities in the tailings slurry pass through the filter holes and fall, while most of the tailings slurry is filtered out on the surface of the filter screen. At this time, the servo motor drives the stirring rod to rotate, so that the stirring rod drives the scraper close to the surface of the filter screen to rotate, pushing the filtered tailings slurry to slide on the surface of the filter screen, avoiding the filtered tailings slurry from accumulating on the surface of the filter screen for a long time to block the filter holes and affect the normal filtration of the subsequent tailings slurry. The filtration efficiency is high. The subsequent electric push rod enters the discharge plate by pulling the baffle, and the rotating scraper will push the filtered tailings slurry along the discharge port into the discharge plate for discharge, thereby realizing the rapid collection of the filtered tailings slurry and making it more convenient to use.

[0012] 2. When the tailings slurry enters the main cylinder along the feeding hopper, it will fall on the guide plate and then enter the separation cylinder due to gravity and fall again. At this time, the rotating servo motor drives the stirring rod to rotate. During the rotation process, the stirring rod will drive the separation piece to hit the tailings slurry and cut the fallen tailings slurry. When the subsequent tailings slurry falls from the separation cylinder, the stirring blade will cut and stir the fallen tailings slurry again, avoiding the tailings slurry from solidifying and mixing for a long time before filtration, further improving the subsequent filtration efficiency of the tailings slurry.

DETAILED DESCRIPTION

[0019] Example 1, with reference to Figure 1-4 A tailings slurry filtering device includes a main cylinder 1 and a hopper 101. The hoppers 101 are fixed to the left and right ends of the top of the main cylinder 1. A servo motor 102 is fixed to the upper part of the main cylinder 1. A stirring rod 103 is rotatably connected to the lower part of the transmission shaft at the output end of the servo motor 102. A separation sheet 104, a stirring blade 105 and a scraper 106 are fixed to the outer wall of the stirring rod 103 from top to bottom. An inner cylinder 2 is fixed to the lower part of the main cylinder 1. A guide plate 201 is fixed to the upper part of the inner cylinder 2. A separation cylinder 202 is fixed to the middle of the bottom end of the plate 201, a partition plate 203 is fixed to the inner wall of the separation cylinder 202, a filter screen 204 is fixed to the lower inside of the inner cylinder 2, a discharge plate 3 is fixed to the lower right side of the main cylinder 1, an electric push rod 301 is fixed horizontally on the right side of the top of the discharge plate 3, a baffle 302 is fixed to the left side of the push rod at the output end of the electric push rod 301, a lower electric push rod 303 is fixed horizontally on the right side of the bottom of the inner cylinder 2, and a water baffle 304 is fixedly connected to the left side of the push rod at the output end of the lower electric push rod 303.

[0020] The guide plate 201 is arranged in a "funnel" shape, the middle of the separation cylinder 202 is connected to the opening at the bottom of the guide plate 201, and the stirring rod 103 is vertically arranged to penetrate the middle of the separation cylinder 202 and the guide plate 201;

[0021] There are eight separation sheets 104 and eight partition plates 203, which are arranged in a circular shape around the stirring rod 103 and the middle of the separation cylinder 202 respectively.

[0022] The main function of the partition plate 203 is to prevent the rotating separation plate 104 from contacting the falling tailings slurry, and the tailings slurry rotates with the rotation of the separation plate 104;

[0023] When the tailings slurry enters the main cylinder 1 along the feeding hopper, it will fall on the guide plate 201 and then enter the separation cylinder 202 due to gravity and fall again. At this time, the rotary servo motor 102 drives the stirring rod 103 to rotate. During the rotation process, the stirring rod 103 drives the separation plate 104 to hit the tailings slurry and cut the fallen tailings slurry, thereby preventing the tailings slurry from solidifying and mixing together for a long time before filtration.

[0024] The separation pieces 104 are just in close contact with the bottom end of the partition plate 203 , and the stirring blades 105 are just set at the bottom end of the separation cylinder 202 .

[0025] When the tailings slurry falls from the separation drum 202 after being cut, the rotating stirring blades 105 will cut and stir the falling tailings slurry again, preventing the tailings slurry from solidifying and mixing together for a long time before filtration, further improving the subsequent filtration efficiency of the tailings slurry.

[0026] Example 2: Example 2 differs from Example 1 in that, in this example, a discharge port communicating with the interior of the discharge plate 3 is provided at the right opening in the middle of the inner cylinder 2. The discharge port is located on the right side of the upper surface of the filter screen 204, and the baffle 302 is embedded in the leftmost portion of the discharge port.

[0027] After a large amount of filtered tailings slurry accumulates on the filter screen 204, the electric push rod 301 pulls the baffle 302 into the discharge plate 3, and the rotating scraper 106 pushes the filtered tailings slurry along the discharge port into the discharge plate 3 for discharge, thereby realizing rapid collection of the filtered tailings slurry and making it more convenient to use.

[0028] Three scrapers 106 are provided at the bottom of the stirring rod 103. The scrapers 106 are arranged in a circular shape around the middle of the stirring rod 103. The bottom and outer sides of the scrapers 106 are respectively in close contact with the upper surface of the filter screen 204 and the inner wall of the inner cylinder 2;

[0029] When the tailings slurry falls on the filter screen 204, the impurities in the tailings slurry pass through the filter holes and fall, while most of the tailings slurry is filtered out of the upper surface of the filter screen 204. At this time, the servo motor 102 drives the stirring rod 103 to rotate, so that the stirring rod 103 drives the scraper 106 close to the upper surface of the filter screen 204 to rotate, pushing the filtered tailings slurry to slide on the upper surface of the filter screen 204, avoiding the filtered tailings slurry from accumulating on the upper surface of the filter screen 204 for a long time to block the filter holes and affect the normal filtration of the subsequent tailings slurry, and the filtration efficiency is high.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
