Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, and particularly relates to a wet automatic magnetic separator. Background Art

[0002] A magnetic separator is a screening device used to remove iron powder from powdery granular materials. Magnetic separators are widely used in resource recovery, wet magnetic separation of various minerals, and also for iron removal operations of materials such as coal, non-metallic minerals, and building materials. It is one of the most widely used and highly versatile machine types in the industry; a magnetic separator can greatly improve production efficiency, reduce floor space, and lower labor costs.

[0003] After the magnetic separator completes the screening of magnetic substances in the raw materials, the magnetic substances selected by magnetic separation adhere to the inner wall of the magnetic separation cylinder of the magnetic separator and are not easy to remove, thus affecting the magnetic separation effect of the magnetic separator. Therefore, it is necessary to flush the inner wall with water; for the currently commonly used magnetic separator, the magnetic separation cylinder is connected to a tap water pipe and directly flushed with tap water. This method is relatively dependent on the local tap water pressure. If the flushing is carried out during the peak period of urban residents' water use, it is very likely that due to the low tap water pressure, the flushing water pressure will be low, resulting in an unsatisfactory flushing effect. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a wet automatic magnetic separator that can thoroughly flush the magnetic substances adhering to the inside of the magnetic separation cylinder, keep its magnetic separation effect good, has a large flushing water pressure, and the flushing effect is not affected by the tap water pressure.

The magnetic separator is provided with a magnetic separation cylinder, and the magnetic separation cylinder is provided with a feed inlet, a discharge outlet, and an iron discharge port. A flushing device for diluting materials is provided on the side of the magnetic separation cylinder. The flushing device includes a water tank, and the water tank is provided with a water inlet and a water outlet. The water inlet is connected to a water supply device, and the water outlet is connected to the inside of the magnetic separation cylinder through a water outlet pipe. A pressurizing device is provided on the water outlet pipe.

[0006] Preferably, the feed inlet is arranged below the magnetic separation cylinder, and the discharge outlet is arranged above the magnetic separation cylinder.

[0007] Preferably, a feed electromagnetic valve is provided at the feed inlet, a discharge electromagnetic valve is provided at the discharge outlet, and an iron discharge electromagnetic valve is provided at the iron discharge port. The electromagnetic valves are connected to a control system.

[0012] Preferably, long strip-shaped spray openings are spaced at the center of the blade, and a number of circular spray openings are arranged around the periphery of the long strip-shaped spray openings.

[0013] In summary, the utility model has the following beneficial effects:

[0014] 1. The utility model adds a flushing device to the magnetic separator. The flushing device includes a water tank and a booster pump. The flushing device removes the magnetic substances after magnetic separation, so that when flushing, the water volume is larger and the water pressure is stronger, without relying on the water volume and water pressure of tap water, making the flushing efficiency higher, the flushing more comprehensive, clean and thorough. Its structure is simple and easy to use, which can improve work efficiency, is applicable to various models of magnetic separators, and does not require changing the original structure of the magnetic separator.

[0015] 2. At the end of the water outlet pipe, there is a spray booster head. The spray booster head adopts a combination of long strip-shaped spray openings and circular spray openings.
