Description

Technical Field

[0001] This application belongs to the field of mineral screening technology, specifically relating to a mineral processing settling tank anti-ore accumulation device. Background Technology

[0002] In mineral processing tests and production, settling tanks are crucial solid-liquid separation equipment. Traditional settling tanks typically employ a design with a continuous sloping slab (steel plate) at the bottom, extending from back to front. The discharge outlet is located in the middle of the front of the settling tank, with straight transition structures on both sides of the outlet (see reference). Figure 1 and Figure 2 (As shown).

[0003] This structure has significant defects: 1. Mineral sample residue problem: After the slurry settles, there is a height difference between the straight area on both sides of the bottom and the discharge port, which causes the residual mineral sample to accumulate in the dead corners on both sides of the discharge port, making it difficult to clean it completely.

[0004] 2. Low cleaning efficiency: When relying on manual hydraulic flushing, the water flow cannot push the mineral samples on both sides towards the central discharge port, requiring repeated flushing or even mechanical intervention, which increases the intensity of operation and affects the continuity of experiments and production.

[0005] 3. Experimental accuracy deviation: Residual ore samples cause inconsistencies in the amount of solid phase in each sedimentation experiment, affecting the concentration calculation and the stability of subsequent processes. Utility Model Content

[0006] The purpose of this application is to provide a device for preventing ore accumulation in a mineral processing settling tank, which solves the problems of ore sample residue, low cleaning efficiency, and experimental accuracy deviation in existing mineral processing settling tanks.

[0007] The objective of this application is achieved through the following technical solution: A mineral processing settling tank anti-accumulation device includes a settling tank body. Inside the settling tank body, there are left and right inclined plates located above the bottom plate. The left and right inclined plates are both arranged downward from back to front and downward from both sides to the middle. An inclined joint is formed between the left and right inclined plates. The settling tank body is provided with a discharge port opposite to the bottom of the inclined joint.

[0008] Furthermore, the main body of the settling tank is a cuboid structure with an opening at the top.

[0009] Furthermore, the main body of the settling tank is welded from steel plates.

[0010] Furthermore, the bottom of the settling tank body is provided with rolling wheels located at the four corners.

[0011] Furthermore, the ore outlet is located at the front middle position of the settling tank body.

[0012] Furthermore, the left and right slope plates are arranged symmetrically.

[0013] Furthermore, the inclination angle of the left and right ramps from back to front is 15-20°.

[0014] Furthermore, the inclination angles of the left and right ramps from both sides to the middle are both 15-25°.

[0015] Furthermore, both the left and right slope plates are made of steel plates.

[0016] Furthermore, both the left and right slope plates are welded into the main body of the settling tank, and the beveled joint formed between the left and right slope plates is a beveled weld.

[0017] The beneficial effects of this application are: to modify the bottom structure of the existing settling tank, eliminate the straight side structure, and form a bidirectional flow guide slope. By arranging the slope from back to front and from both sides to the middle, the end of the slope is seamlessly connected to the edge of the discharge port, eliminating the height difference and avoiding or reducing the retention of mineral particles at the bottom of the tank.

[0018] The aforementioned main solution and its various further alternatives can be freely combined to form multiple solutions, all of which are solutions that can be adopted and claimed in this application; furthermore, the (non-conflicting alternatives) can also be freely combined with each other and with other alternatives. Those skilled in the art, after understanding this solution, will realize from the prior art and common general knowledge that there are many combinations, all of which are technical solutions to be protected in this application, and will not be exhaustively listed here.

[0024] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0025] refer to Figure 1and Figure 2 As shown, the bottom of the existing settling tank adopts a full-surface sloping plate 5 (steel plate) design from back to front. The ore discharge port 4 is located in the center of the front of the settling tank. The two sides of the ore discharge port are straight transition structures, which leads to ore sample residue, resulting in low cleaning efficiency and experimental accuracy deviation.

[0026] Example 1 refer to Figure 3 and Figure 4 As shown, a mineral processing settling tank anti-accumulation device includes a settling tank body 1, a rolling wheel 2, a discharge port 4, a left slope plate 6, and a right slope plate 7. The settling tank body 1 is used for holding mineral samples and water.

[0027] The main body 1 of the settling tank is equipped with a left slope plate 6 and a right slope plate 7 located above the bottom plate 3. The left slope plate 6 and the right slope plate 7 are both arranged downward from back to front, and the left slope plate 6 and the right slope plate 7 are both arranged downward from both sides to the middle. A sloping joint is formed between the left slope plate 6 and the right slope plate 7. The left slope plate 6 and the right slope plate 7 form a bidirectional flow slope from back to front and from both sides to the middle, that is, a V-shaped structure, to achieve bidirectional flow of mineral samples.

[0028] The main body 1 of the settling tank is provided with a ore discharge port 4 that is opposite to the bottom of the inclined joint 8. The ore discharge port 4 is used as the ore discharge point. The existing straight side structure is eliminated by the left inclined plate 6 and the right inclined plate 7 to form a new guide slope. The end of the slope is seamlessly connected to the edge of the ore discharge port to eliminate the height difference.

[0029] The settling tank body 1 is a rectangular structure with an open top, facilitating the pouring of mineral samples and water into the settling tank body 1 from above. The settling tank body 1 is welded from steel plates and specifically includes a front plate, a rear plate, a left side plate, a right side plate, and a bottom plate 3. The bottom of the settling tank body 1 is equipped with rollers 2 located at the four corners, facilitating the movement and relocation of the settling tank body 1. Preferably, the rollers 2 are brakeable rollers, which facilitate the fixation of the settling tank body 1 for settling operations.

[0030] The discharge port 4 is located in the middle of the front part (front plate) of the settling tank body 1, which facilitates the downward convergence of mineral samples from back to front, and also facilitates the downward convergence of mineral samples from both sides to the middle. The two-way convergence direction ultimately leads to the discharge port 4, where the mineral samples are discharged, avoiding mineral sample residue caused by the straight transition structure. The discharge port 4 is equipped with a valve, which is closed during settling and opened during ore discharge.

[0031] The left ramp 6 and the right ramp 7 are arranged symmetrically to make full use of the space on both sides and ensure a reasonable overall structural layout. The inclination angle of the left ramp 6 and the right ramp 7 from back to front is 15~20°, and the inclination angle of the left ramp 6 and the right ramp 7 from both sides to the middle is 15~25°.

[0032] Both the left slope plate 6 and the right slope plate 7 are steel plates. Both the left slope plate 6 and the right slope plate 7 are welded inside the main body 1 of the settling tank. The beveled joint 8 formed between the left slope plate 6 and the right slope plate 7 is a beveled weld. It is preferable to use downslope welding technology from the inside of the settling tank to the discharge port to ensure that the weld surface is smooth and consistent with the slope of the steel plates on both sides, so as to avoid mineral particles from being retained at the weld.

[0033] Example 2 A mineral processing settling tank anti-accumulation device, the specific implementation process is as follows: a. The original bottom whole slope plate 5 is changed to a left slope plate 6 and a right slope plate 7 centered on the two sides towards the ore discharge port 4, forming a V-shaped structure.

[0034] b. The inclined joint 8 between the left slope plate 6 and the right slope plate 7 is welded at the internal high and the low ore outlet 4.

[0035] c. The mineral sample, after being processed by other mineral processing equipment, is pumped into the settling tank 1 for settling.

[0036] d. After settling, drain the upper part of the water in the main body 1 of the settling tank using a water pipe.

[0037] e. Use tools to remove the lower mineral sample from the main body 1 of the settling tank into a sample bag.

[0038] f. Open valve 4 at the mine outlet, flush out the remaining mineral sample at the bottom with clean water, collect it in a basin to clarify, pour out the water, and take out the mineral sample into the sample bag.

[0039] The foregoing basic examples and their further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in this application. In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
