TECHNICAL FIELD

[0001] The utility model relates to smelting equipment technical field, concretely relates to a mineral powder containing sewage settlement device. BACKGROUND

[0002] In nonferrous smelting process, sampling and testing are needed from raw materials, intermediate products, by-products and products, especially the sampling of raw materials is particularly critical, which relates to mineral powder settlement. In the sampling process, sampling devices such as sampling shovel and sampling drill are usually used, after sampling is completed, the sampling device needs to be cleaned, and a large amount of mineral powder containing sewage is generated. On the other hand, the tools such as sample preparation disc and sample preparation shovel used in sample preparation also stick with mineral powder, and a large amount of mineral powder containing sewage is also generated after being washed.

[0003] The mineral powder containing sewage generated in the sampling and sample preparation process is usually directly discharged to the water treatment system, and the following two important problems usually occur during the discharge process: (1) the mineral powder in the mineral powder containing sewage contains a large amount of valuable elements, which causes the loss of valuable elements when directly discharged; (2) the mineral powder in the sewage is easy to block the pipeline after a long time of settlement, causing the sewer to be blocked, which needs to be cleaned manually. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the above problems, the utility model provides a mineral powder containing sewage settlement device.

[0005] The technical scheme of the utility model is realized as follows: a mineral powder containing sewage settlement device, which comprises a scouring pool, a water inlet pipe is arranged at the upper end of the scouring pool, a scouring water outlet is arranged at the right side of the lower end of the scouring pool, a screen is arranged on the scouring water outlet, the scouring water outlet is connected with a primary sedimentation tank through a water pipe A, a primary sedimentation water outlet is arranged at the right side of the primary sedimentation tank, the primary sedimentation water outlet is connected with a secondary sedimentation tank through a water pipe B, a sewage outlet is arranged at the bottom end of the secondary sedimentation tank, and the bottom heights of the scouring pool, the primary sedimentation tank and the secondary sedimentation tank are arranged in a stepped manner from high to low.

[0006] Preferably, the distance between the lower end of the water pipe of the primary sedimentation tank and the bottom of the tank is 10-20 cm;

[0007] Preferably, the distance between the primary sedimentation water outlet and the bottom of the primary sedimentation tank is 20-40 cm;

[0008] Preferably, the distance between the lower end of the water pipe of the primary sedimentation tank and the bottom of the tank is 10-20 cm;

[0009] The utility model discloses beneficial effect is: the utility model increases the screen in the washing pool lower water outlet, can effectively filter out the big granule sundries, reduces the risk of blockage, utilizes the height difference of inlet and outlet water gap, and the mineral powder in sewage is effectively settled in the first, second settlement pond, and the mineral powder in sewage is effectively recovered by regular cleaning, avoids the loss of valuable element, and the mineral powder particle in the sewage that discharges simultaneously is greatly reduced, reduces the risk of sewer pipeline blockage.
