Description

Technical Field

[0001] The utility model relates to the field of slime treatment technology, in particular to a high-efficiency slime thickening tank. Background Art

[0002] Slime thickening is an important link in the coal processing process, mainly involving the solid-liquid separation and concentration improvement of coal slime water. Under the action of gravity, the solid particles in the coal slime water will gradually sink to form a compression zone, while the upper part will gradually become clear.

[0003] Traditional thickening technology generally uses a thickening tank to introduce coal slime water into the tank for direct natural sedimentation separation. However, this method is affected by the impact of coal slime water, often resulting in incomplete separation of solid particles from water, and it is impossible to separate solid particles and water with higher purity that meet the requirements. Content of the Utility Model

[0004] In order to solve the above problems existing in the prior art, the utility model provides a high-efficiency slime thickening tank.

[0005] The high-efficiency slime thickening tank provided by the utility model adopts the following technical scheme:

[0006] A high-efficiency slime thickening tank includes a tank body. A partition board is horizontally arranged in the tank body. The lower part of the partition board is set as a separation chamber, and the upper part of the partition board is set as a water guiding chamber. A connecting bin cylinder communicating with the separation chamber and the water guiding chamber respectively is vertically installed on the partition board. A buffer chamber is installed on the outer wall of the connecting bin cylinder in the water guiding chamber. The bottom of the buffer chamber communicates with the separation chamber. An outlet pipe for discharging solid particles and a feed pipe for introducing coal slime water into the buffer chamber are installed on the separation chamber.

[0007] By adopting the above technical scheme, after the coal slime water impacts into the buffer chamber, the impact force is weakened. After flowing downward, natural sedimentation separation is carried out. The solid particles sink and are discharged through the outlet pipe, and the water flows upward and is discharged through the water guiding chamber. The high-efficiency slime thickening tank is simple and convenient to operate, promotes the full precipitation of solid particles, and realizes the purpose of fully separating solid particles and water in the coal slime water.

[0008] Optionally, the buffer chamber includes a backwash plate with the top fixedly connected to the outer wall of the connecting bin cylinder and inclined downward. A material supporting plate is horizontally fixedly connected to the inner wall at the bottom of the backwash plate. A gap is provided between the material supporting plate and the connecting bin cylinder.

[0009] By adopting the above technical scheme, the impact force of the coal slime water is effectively reduced after impacting on the backwash plate, the material supporting plate and the connecting bin cylinder.

[0010] Optionally, a material distributing cone with the tip facing upward is arranged below the connecting bin cylinder.

[0011] By adopting the above technical solution, the solid particles are effectively and evenly dispersed after falling onto the material distribution cone, which is beneficial to avoid the concentrated accumulation of solid particles and affect the external discharge.

[0012] Optionally, a drainage plate is vertically arranged on the top wall of the water guide bin, and a gap is arranged between the drainage plate and the bottom wall of the water guide bin.

[0013] By adopting the above technical solution, the drainage plate can guide the flow of water and at the same time has the effect of reducing the impact of water flow.

[0014] Optionally, a shock reduction plate is inclinedly arranged in the water guide bin.

[0015] By adopting the above technical solution, the shock reduction plate further reduces the impact force of the water flow.

[0016] Optionally, the included angle between the shock reduction plate and the horizontal plane is 60°.

[0017] Optionally, an overflow pool is arranged on the outer periphery of the water guide bin.

[0018] By adopting the above technical solution, the overflow pool is convenient for slowing down the flowing water and draining water in time.

[0019] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0020] After the slime water impacts into the buffer chamber, the impact force is weakened. After discharging downward, natural sedimentation separation is carried out. The solid particles sink and are discharged through the discharge pipe, and the water flows upward and is discharged through the water guide bin. The slime high-efficiency thickening tank is simple and convenient to operate, promotes the full precipitation of solid particles, and realizes the purpose of fully separating the solid particles and water in the slime water;

[0021] The solid particles are effectively and evenly dispersed after falling onto the material distribution cone, which is beneficial to avoid the concentrated accumulation of solid particles and affect the external discharge;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following is a further detailed description of the present utility model with reference to the attached Figure 1 drawings.

[0026] An embodiment of the utility model discloses a high-efficiency coal slime thickening tank. Refer to Figure 1 , the high-efficiency coal slime thickening tank includes a tank body 1, the tank body 1 is a conical tank, a partition plate 10 is fixedly connected horizontally inside the tank body 1, and the partition plate 10 divides the tank body 1 into a separation chamber 11 and a water guiding chamber 12. The separation chamber 11 is located at the bottom, and the water guiding chamber 12 is located at the top.

[0027] Refer to Figure 1 , a feed pipe 2 and a discharge pipe 3 are installed at the separation chamber 11. The feed pipe 2 is used to convey coal slime water into the separation chamber 11, and the discharge pipe 3 is used to discharge the precipitated solid particles. A pump body 30 is installed on the discharge pipe 3.

[0028] Refer to Figure 1 , a connecting bin cylinder 4 is fixedly connected vertically in the middle of the partition plate 10, and the connecting bin cylinder 4 is respectively communicated with the separation chamber 11 and the water guiding chamber 12. A buffer chamber 5 is installed on the outer wall of the connecting bin cylinder 4 located in the separation chamber 11. The buffer chamber 5 includes a backwashing plate 50 inclined from top to bottom. A supporting plate 51 is fixedly connected horizontally on the inner side wall of the backwashing plate 50, and a gap for the coal slime water to drain downward is left between the supporting plate 51 and the outer wall of the connecting bin cylinder 4.

[0029] Refer to Figure 1 , a material distributing cone 6 with a pointed end facing upward is installed below the connecting bin cylinder 4. After the coal slime water is discharged downward from the buffer chamber 5, the solid particles are evenly dispersed by the material distributing cone 6, avoiding concentrated accumulation at the bottom of the tank body 1 and affecting the external discharge.

[0030] Refer to Figure 1 , a plurality of vertical drainage plates 7 are fixedly connected horizontally at the top of the water guiding chamber 12. The drainage plates 7 are used to guide the water to be discharged externally and play a certain buffering role at the same time. A gap for water flow is left between the drainage plates 7 and the partition plate 10. In order to further reduce the water flow impact, a plurality of inclined impact reducing plates 8 are also fixedly connected in the water guiding chamber 12. The inclination angle of the impact reducing plates 8 relative to the horizontal direction is 60°. An overflow pool 9 is installed on the outer periphery of the top of the tank body 1, and the overflow pool 9 is communicated with the water guiding chamber 12 for discharging the separated water.

[0031] The implementation principle of the high-efficiency coal slime thickening tank in the embodiment of the utility model is as follows: The coal slime water enters the buffer chamber 5 through the feed pipe 2. After the coal slime water impacts the connecting bin cylinder 4, the backwashing plate 50 and the supporting plate 51, the impact force is reduced. Then the coal slime water is conveyed downward into the separation chamber 11. Among them, the solid particles sink under the action of their own weight and are evenly dispersed by the material distributing cone 6. The solid particles at the bottom are discharged through the discharge pipe 3 under the action of the pump body 30. The separated water flows upward through the connecting bin cylinder 4 into the water guiding chamber 12. The water is blocked by the drainage plates 7 and the impact reducing plates 8, and the impact energy is further reduced. After the water enters the overflow pool 9, it is discharged. [[ID=I8]]

[0032] This high-efficiency coal slime thickening tank is simple and convenient to operate, which promotes the full precipitation of solid particles and realizes the purpose of fully separating solid particles and water in the coal slime water.
