Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank technology, and in particular to a mineral slurry classification sedimentation tank. Background Technology

[0002] In the field of mineral processing, slurry classification and sedimentation tanks play a crucial role. This specialized equipment can effectively separate coarse and fine particles in slurry, significantly improving mineral processing efficiency through precise classification. Its structural design and operation process demonstrate a high degree of scientific rigor and practicality.

[0003] Existing technology discloses a grading sedimentation tank, which includes a receiving tank through which materials flow. Several parallel baffles are spaced apart within the receiving tank, dividing it into several receiving spaces. Each receiving space has a discharge port at its bottom, and the height of each baffle is less than the height of the receiving tank. Because baffles of different heights are present within the receiving tank, when materials pass through each baffle, the concentration and fineness of the materials settling in the corresponding receiving spaces vary under the influence of gravity. Therefore, the materials flowing out of the discharge ports of the receiving spaces are graded, which is beneficial for material sorting. This invention can grade materials without the need for a classifier, and is not only simple in structure and easy to use, but also requires little investment, has low cost, and is economical and practical.

[0004] The aforementioned device uses gravity sedimentation to remove particulate matter from sewage, but it cannot handle scum floating on the water surface.

[0005] Therefore, it is necessary to provide a slurry classification sedimentation tank to solve the above-mentioned technical problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a mineral slurry classification sedimentation tank that can better remove cotton fibers from cotton seeds, which is more conducive to the hulling of cotton seeds by cotton seed hulling machines.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] The slurry classification sedimentation tank includes: a first sedimentation tank for cleaning floating matter and a second sedimentation tank connected thereto;

[0009] The first sedimentation tank has an inlet pipe on its side wall, a first partition plate is detachably installed inside the first sedimentation tank, and a connecting pipe is installed on the inner side of the tank wall of the first sedimentation tank, with the lower end of the connecting pipe located in the water.

[0010] The second sedimentation tank is equipped with an outlet pipe on one side;

[0011] The first sedimentation tank and the second sedimentation tank are connected by a connecting pipe.

[0012] Preferably, a slot is installed on the inner side of the wall of the first sedimentation tank, and the first partition is slidably connected to the slot.

[0013] Preferably, the upper end of the first sedimentation tank and the second sedimentation tank is provided with a cleaning port.

[0015] Preferably, the second sedimentation tank is further provided with a third baffle.

[0016] Preferably, the first sedimentation tank is equipped with an exhaust pipe that communicates with the outside air.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) This utility model achieves the separation effect of floating impurities in water by setting a first baffle;

[0019] (2) By setting a second baffle to block the water flow, the kinetic energy of the small water body is reduced, thus making the water flow more gentle and conducive to the further sedimentation of particulate matter in the water.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0027] In the process of mineral slurry treatment, the generation of floating matter (or scum, foam) is a common phenomenon, mainly caused by physical, chemical or biological factors, such as mineralization bubbles, excessive or incompletely reacted mineral processing agents, etc. The inventors found that most existing graded sedimentation tanks use gravity sedimentation to deposit large and small particulate impurities in the water to the bottom of the tank, but the floating matter floating on the water surface cannot be effectively separated.

[0028] First embodiment:

[0029] like Figure 1 As shown, the slurry classification sedimentation tank provided by this utility model includes: a first sedimentation tank 10 for cleaning floating matter and a second sedimentation tank 20 connected thereto.

[0030] like Figure 1-2 As shown, the first sedimentation tank 10 is a long, rectangular tank made of concrete. A through hole for installing an inlet pipe 11 is pre-drilled in the middle of its side wall. The inlet pipe 11 is T-shaped, with the horizontal section extending to the outside of the first sedimentation tank 10 and the vertical section located inside. Water enters the first sedimentation tank 10 through the horizontal section of the inlet pipe 11. Figure 2 As shown, in the first sedimentation tank 10, a vertical slot 121 is poured into the opposite sides of the tank wall 14. The slot 121 is U-shaped, and the first partition 12 is inserted into the slot 121. The lower end of the slot 121 is closed to support the first partition 12. Figure 1 As shown, the first partition 12 is not completely separated from the bottom of the first sedimentation tank 10, and has a channel for water to pass through. On the other hand, the pool wall 14 of the first sedimentation tank 10 has a through hole for installing the connecting pipe 13 on the side corresponding to the water inlet pipe 11. The difference is that the position of the through hole is lower than the position of the through hole for installing the water inlet pipe 11. The connecting pipe 13 has the same structure as the water inlet pipe 11, both being T-shaped. Its lower end is located in the water, and its upper end is sealed with a sealing cap 111.

[0031] like Figure 1 As shown, the second sedimentation tank 20 has the same width as the first sedimentation tank 10. It can be cast in one piece with concrete during construction. There is a tank wall 14 between the two sedimentation tanks, and the connecting pipe 13 is installed on the tank wall 14. In addition, a through hole for installing the outlet pipe 21 is reserved on the side of the second sedimentation tank 20 corresponding to the side where the connecting pipe 13 is installed. The outlet pipe 21 and the inlet pipe 11 are at the same horizontal height.

[0032] like Figure 1The arrows indicate the flow trajectory and direction of the water. First, external water enters through inlet pipe 11 and then exits from the lower end of inlet pipe 11 into the first sedimentation tank 10. The first baffle 12 is tightly attached to the left side of inlet pipe 11. Particulate matter in the water sinks, while floating matter rises. Therefore, the particulate matter and floating matter separate in the area to the left of the first baffle 12. Finally, as shown... Figure 3 As shown, staff can open the cover plate on the cleaning port 16 at the upper end of the first sedimentation tank 10 to retrieve the floating objects gathered on the left side of the first partition 12.

[0033] The separation of floating impurities in the water body is achieved by setting the first baffle 12.

[0034] Second embodiment:

[0035] like Figure 1 As shown, the second sedimentation tank 20 is equipped with a second baffle 22. It should be noted that the structure of the second baffle 22 is the same as that of the first baffle 12 and the connection method with the tank wall 14 of the second sedimentation tank 20, which will not be described again here. The water flow that enters the second sedimentation tank 20 horizontally through the connecting pipe 13 impacts the second baffle 22. The upper end of the second baffle 22 is above the water surface and the lower end is in the water body. Therefore, the second baffle 22 guides the water flow to pass under the second baffle 22.

[0036] By setting a second baffle 22 to block the water flow, the kinetic energy of the smaller water body is reduced, thus making the water flow more gentle and facilitating the further sedimentation of particulate matter in the water.

[0037] Third embodiment:

[0038] like Figure 1 As shown, the second sedimentation tank 20 is also provided with a third baffle 23. The structure of the third baffle 23 and the connection method with the second sedimentation tank 20 are the same. The third baffle 23 is located to the left of the second baffle 22. The area between the two is the same as the structure of the left end of the first baffle 12 in the first sedimentation tank 10, which is the secondary separation area for floating objects in the water.

[0039] By setting a third baffle 23, the floating matter remaining in the first sedimentation tank 10 and entering the second sedimentation tank 20 can be further separated.

[0040] Fourth embodiment:

[0041] like Figure 2-3 As shown, an exhaust pipe 15 is installed inside the first sedimentation tank 10. The shape of the exhaust pipe 15 is as follows: Figure 3 As shown, one end of the exhaust pipe 15 is connected to the first sedimentation tank 10, and the other end is connected to the outside air. Therefore, the light gas generated during the sedimentation of sewage in the first sedimentation tank 10 can be discharged through the exhaust pipe 15 to prevent excessive internal pressure.

[0042] Working principle: External water enters through the inlet pipe 11 and is then discharged from the lower end of the inlet pipe 11 into the first sedimentation tank 10. The first baffle 12 is close to the left side of the inlet pipe 11. Particles in the water sink, while floating objects float to the top. Thus, the particles and floating objects are separated in the area to the left of the first baffle 12.

[0043] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
