Description

Technical Field

[0001] This utility model relates to the technical field of unloading equipment for wet magnetic separators, specifically to an unloading water tank for a wet magnetic separator. Background Technology

[0002] A wet magnetic separator is a mineral processing equipment. Its working principle is that when the slurry enters the separation tank, the magnetic materials in the slurry can be separated by the rotation of the drum and the magnetic field of the magnetic system. After the magnetic materials leave the magnetic field area, they are usually flushed into the concentrate collection tank by the unloading water, while the non-magnetic and weakly magnetic materials flow into the tailings collection tank.

[0003] The unloading water tank is an important structure to ensure that magnetic materials are smoothly removed from the drum and discharged into the concentrate collection tank. This structure is usually made by drilling several small holes at certain intervals on the main water pipe or by installing unloading water nozzles at certain intervals on the main water pipe. The water outlets in the above structures are usually less than 8mm. Since the unloading water is mostly mineral processing circulating water, the water quality is difficult to guarantee, which makes the water outlets easy to clog. At the same time, the water pressure, coverage shape, and water volume in the water outlet area and the intersection area between adjacent water outlets cannot be kept uniform, which easily leads to uneven unloading and ore carrying on the drum. It can even cause mineral processing tailings, which seriously affects the operating efficiency of wet magnetic separators and the profits of manufacturers.

[0004] Therefore, developing and designing a wet magnetic separator unloading water tank that provides uniform and consistent water output, ensures efficient ore unloading, is not prone to clogging, and improves operational efficiency is an urgent problem to be solved at this stage. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a wet magnetic separator unloading water tank. Utilizing the internal thread structure of the water distribution pipe, water can be sprayed out in a spiral shape. Under the action of the baffles inside the tank, the water flow surges and rises evenly and overflows from the water outlet tongue plate, resulting in more uniform water discharge, which is beneficial for unloading ore and improves the unloading effect. It is also less prone to clogging, ensuring the working efficiency of the wet magnetic separator and avoiding the problem of ore being carried along the drum. The structure is simple and the design is reasonable.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a wet magnetic separator unloading water tank, comprising:

[0008] The tank extends along a first direction and includes a front plate and a rear plate. Both the front and rear plates are parallel to and vertically arranged along the first direction. The upper edge of the front plate is lower than the upper edge of the rear plate. A water outlet tongue plate extending outside the tank is provided at the upper edge of the front plate. The water outlet tongue plate is inclined downward in a direction away from the rear plate. A plurality of partitions distributed along the first direction are provided inside the tank. The upper edge of the partitions is lower than the highest point of the water outlet tongue plate.

[0009] A water inlet pipe is located directly above the tank and extends along the first direction; the water inlet pipe is provided with several branch pipes, the lower ends of which extend into the tank and are located between two adjacent partitions; the branch pipes have internal threads.

[0010] A scraper is disposed on the tank body and located above the water outlet tongue plate.

[0011] As a preferred technical solution, the tank body further includes a bottom plate and two end plates. The front plate and the rear plate are both disposed on the bottom plate and located between the two end plates. The front plate, the rear plate, the bottom plate, and the two end plates are welded together to form the tank body.

[0012] As a preferred technical solution, there is a gap between the lower edge of the partition and the bottom plate;

[0013] And / or, the partition is provided with openings.

[0014] As a preferred technical solution, a roller is provided on one side of the trough, and the scraper is in clearance fit with the cylindrical surface of the roller on the side edge away from the trough.

[0015] As a preferred technical solution, the tank is provided with a fixed plate fixedly connected thereto, the scraper is placed on the fixed plate, and a pressure plate is provided above the scraper, the pressure plate pressing the scraper tightly on the fixed plate.

[0016] As a preferred technical solution, the scraper is inclined and tilted downwards in a direction away from the rear plate of the trough.

[0017] As a preferred technical solution, the angle between the water outlet tongue plate and the front plate of the tank is set to 45-80°.

[0018] As a preferred technical solution, the tank is horizontally positioned;

[0019] And / or, both ends of the tank along its length are provided with supports, and the water inlet pipe is fixed to the supports by U-bolts.

[0020] As a preferred technical solution, one end of the water inlet pipe is provided with a plug.

[0021] As a preferred technical solution, the inner diameter of the water distribution pipe is greater than 10mm.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. This utility model utilizes the internal thread structure of the water distribution pipe to allow water to be sprayed into the tank in a spiral shape. Under the action of the baffle in the tank, the water flow in the tank surges and rises evenly and overflows from the water outlet tongue plate, making the water discharge more uniform and facilitating ore unloading. This improves the ore unloading effect and makes it less prone to clogging, ensuring the working efficiency of the wet magnetic separator and avoiding the problem of ore being carried along the drum. The structure is simple and the design is reasonable.

[0024] 2. The present invention has a scraper plate above the water outlet tongue plate. The scraper plate can scrape off the residual minerals on the wet magnetic separator drum, which plays an auxiliary role in unloading the ore and further solves the problem of ore carrying on the drum or incomplete unloading.
