Background technique

River sand iron selection has brought a lot of profits to enterprises. At the same time, with the continuous growth of the economy, the technology of river sand iron selection equipment is also constantly improving. At the same time, river sand iron selection equipment will bring more enterprises profits. At present, the iron mining industry is developing rapidly. People have found that many river sands and beaches in dry rivers are rich in iron. The powder loss is low, the selected iron powder is pure, and it is not prone to failure, low energy consumption, and no other equipment is needed.

The river sand iron separation equipment is mainly to screen the river sand to screen out the iron-containing substances in the river sand. Due to the rising steel price, the separation of iron powder in the river sand has a very good effect on the economic development of our country.

The application number is 201520642733.5, which discloses a river sand iron powder extraction device, including a motor, a conveyor belt, and a magnet. A drying furnace is installed on the end face of the motor; a connecting rod is arranged on the upper end face of the drying furnace; the connecting rod There is a cooling device outside; the cooling device is inlaid with a plug; the plug is connected to the support through a wire; the lower end of the support is provided with a base.

Due to the unavoidable existence of some large pieces of sand or stones in the river sand, there will be hidden dangers of damage to the magnetic separation equipment, which will affect its service life and separation efficiency.

Contents of the invention

The purpose of this utility model is to overcome the hidden danger of damage to the magnetic separation equipment caused by the presence of some large sand or stones in the separation process of river sand and iron powder in the prior art, thereby affecting its service life and separation efficiency To solve the problem, a river sand and iron powder separation equipment is provided to reduce equipment wear, save costs and increase production capacity.

The utility model provides a separation device for river sand and iron powder, which is composed of a frame, a feeding trough, a vibrating screen and a downstream trough magnetic separator. The feeding trough, the vibrating sieve and the downstream trough magnetic separator are installed on the frame. The outlet of the feeding trough faces the vibrating sieve, and the downstream trough magnetic separator is installed directly below the vibrating sieve.

The utility model provides a separation device for river sand and iron powder. As a preferred mode, the downstream groove magnetic separator includes a drum, a magnet installed outside the drum and a water tank installed below the drum. The drum is rolled and welded by 5-6mm stainless steel plate, and the end cover is made of aluminum or aluminum alloy and fixed with stainless steel bolts. The motor drives the roller through the reducer. The magnets are mostly open magnets, which are NdFeB or electromagnetic materials.

The utility model provides a river sand and iron powder separation equipment. As a preferred mode, the vibrating screen includes at least one layer of screen mesh. Screens with different meshes can complete the separation of sand and gravel with different particle sizes, and can prevent the sand and gravel with too large particle size from contacting the downstream slot magnetic separator.

The utility model provides a separation device for river sand and iron powder. As an optimal mode, a group of water spray pipes are arranged on the feeding trough. The water spray pipe sprays water while loading materials, which can reduce the dust pollution during feeding, and at the same time, under the impact of water flow, it can drive the materials to quickly enter the next process, improve the productivity of the equipment, and can also simply process the materials , to facilitate the follow-up process, reduce equipment wear, save costs and increase production capacity.

During the use of the utility model, river sand, iron powder ore slurry flows into the feed tank, and large-grained sand and gravel are screened out through equipment such as vibration pulse devices and screens, and the rest of the ore particles are in a loose state and enter the magnetic flow tank along with the water flow. Choose machine. Under the action of the magnetic field, magnetic agglomerates are produced, and the magnetic agglomerates move to the magnetic poles in the pulp under the action of magnetic force, and are adsorbed on the surface of the drum. Since the polarities of the magnetic poles are arranged alternately along the direction of drum rotation, and they are fixed during work, the magnetic cluster generates magnetic stirring when the drum rotates, and the non-magnetic substances loaded in the magnetic cluster are separated from it, and finally stay in the The magnetic group on the surface of the drum is the concentrate. When the concentrate turns to the weak magnetic field area at the edge of the magnetic system, it is washed down by the ore unloading flushing water and enters the concentrate tank, while the non-magnetic materials flow into the water tank under the action of the water flow without being affected by the magnetic force.

Since the utility model arranges the vibrating screen above the magnetic separator in the downstream tank, it can make river sand and iron powder ore slurry flow into the magnetic separator in the downstream tank to screen out sand and stones with larger particle sizes in advance to prevent the particle size from being too large. The gravel is in contact with the downstream tank magnetic separator, which improves the service life and separation efficiency of the equipment.

detailed description

Example 1

As shown in Figure 1, the utility model provides a kind of river sand, iron powder separation device, is made up of frame 1, feed trough 2, vibrating screen 3 and downflow tank magnetic separator 4, feed trough 2, vibrating screen 3 And the downstream trough magnetic separator 4 is installed on the frame 1, the discharge port of the feed trough 2 is facing the vibrating screen 3, a set of water spray pipes is arranged on the feed trough 2, and the downstream trough magnetic separator 4 is installed on the vibrating screen 3. Just below the sieve 3; the downstream slot magnetic separator 4 includes a drum, a magnet installed on the outside of the drum and a water tank installed below the drum.

The utility model comprises the following steps during use:

Step 1: Loading. Mechanical feeding is adopted, and the sand to be processed is directly loaded into the feeding tank 2 with a loader, and the water spray pipe sprays water while loading the material, driving the material to quickly enter the next process;

Step 2: Sifting. Vibrating sieve 3 separates the river sand and stones in the river sand that enters the equipment through the feeding process, so that the required river sand material can enter the next process, and the unnecessary part of the river sand screened out can be recycled for another deal with;

Step 2: Magnetic separation. According to the different magnetic susceptibility coefficients of minerals, magnetic substances and non-magnetic substances are separated by magnetic force and mechanical transmission of the magnetic system. The river sand and iron powder ore slurry enter the downstream slot magnetic separator 4 with the water flow. Under the action of the magnetic field, magnetic agglomerates are produced, and the magnetic agglomerates move to the magnetic poles in the pulp under the action of magnetic force, and are adsorbed on the surface of the drum. Since the polarities of the magnetic poles are alternately arranged along the direction of drum rotation, and they are fixed during work, the magnetic group generates magnetic stirring when the drum rotates, and the non-magnetic substances loaded in the magnetic group are separated from it, and finally stay in the magnetic group. The magnetic group on the surface of the drum is the concentrate. When the concentrate turns to the weak magnetic field area at the edge of the magnetic system, it is washed down by the ore unloading flushing water and enters the concentrate tank, while the non-magnetic materials flow into the water tank under the action of the water flow without being affected by the magnetic force.

Step 4: Row the tail sand. Use a loader or use a conveyor belt to transport to a distant place.

The above description is only illustrative, rather than restrictive, for the utility model, and those skilled in the art understand that any modification, change or equivalent can be made without departing from the spirit and scope defined in the claims , all will fall within the protection scope of the present utility model.
