Description

A distributor for mineral selection

Technical field:

The invention relates to a distributor, in particular to a distributor for mineral selection, which is particularly suitable for a dry mining process.

Background technique:

In the existing beneficiation industry, there are wet beneficiation process and dry beneficiation process. In the wet beneficiation process, the material exists in the form of pulp and is sent to the next process through the chute or pipeline, so there is no cloth in the wet beneficiation process. No need for a distributor.

In the dry beneficiation process, the current general dry beneficiation process pre-selects the bulk material after coarse crushing or medium crushing. Therefore, the material is mainly fed to the beneficiation equipment through the conveyor belt, that is, the conveyor belt is used as the beneficiation equipment. Cloth and unloading device; for continuous powder multi-stage reverse sorting equipment for fine powder or micro-powder dry material, before the material flows from one process to the next, the material needs to be measured first to achieve quantitative dosing. Most of the distributors are weighed by the belt weigher and then cut by the unloading device. However, in the process of cutting, even though we have already weighed, the materials will still accumulate in the unloading device, and the dosing cannot be accurately achieved. When the amount of feed is too large, it will affect the treatment effect of the next process. When the feed amount is small, the processing amount of the next process will be low, and when the fabric of the next process is uneven, the thickness of the material in the next process is inconsistent. At the same time, it will still affect the processing effect of the next process.

Summary of the invention:

It is an object of the present invention to provide a distributor for mineral selection.

In order to achieve the above object, the present invention is achieved as follows:

A hopper for mineral selection includes a fixing member and a movable member, and a material passage is formed between the fixing member and the movable member, and a metering space is disposed on the material passage. The space or area between the fixed part and the movable part forms a flow passage, and when the movable part is active, the animal material flows, and the material is metered in the cloth passing process in the flow process.

Preferably, the metering space is a relatively closed space formed by a partition, a fixing member and a movable member provided on the movable member. The relatively closed space refers to a material that can allow the movable member to freely move while being enclosed in the space without leaking the material, and realizes the accurate metering function of the cloth device while the cloth is in the cloth; the cloth device also has a lock air Its role is to prevent the air from flowing in the material passage, avoiding the flying of materials and polluting the air.

Further, in order to optimize the structure of the distributor, the fixing member is a casing, the movable member is a rotating wheel, the rotating wheel is disposed in the casing, and the partition plate is disposed on an outer surface of the rotating wheel.

In order to further achieve the natural flow of the material, the feed end of the material passage is disposed at the top of the casing, and the object The discharge end of the material passage is disposed at the bottom of the housing. Such an arrangement enables the material to flow from the feed end into the housing from the feed end by its own gravity, and organically combines the rotation of the runner with gravity to measure in the cloth.

To further optimize the structure of the relatively confined space, the inner surface of the housing is concentric with the outer surface of the runner. The structure of the closed space is made simple and easy to implement.

In order to further enable the housing to be easily processed, the inner surface of the lower portion of the housing is vertically disposed.

In order to further enable a uniform cloth, the inner surface of the lower portion of the housing is disposed between the vertical arrangement and the concentric arrangement of the outer surface of the wheel. Such an arrangement enables the material to be slowly relieved when it is transferred to the lower portion of the housing, so that the material can be uniformly removed to achieve a uniform cloth.

On the other hand, in order to optimize the structure of the distributor, the fixing member is a flat plate, and the movable member is a belt conveyor disposed in parallel with the flat plate, and the partition plate is disposed on an outer surface of the belt conveyor.

In order to further realize the natural flow of the material, the flat plate and the belt conveyor are vertically disposed, the feeding end of the material passage is disposed at an upper portion of the flat plate, and the discharge end of the material passage is disposed at a lower portion of the flat plate.

In order to further achieve a quantitative cloth, the partition is evenly disposed on the runner. Such an arrangement makes the size of the relatively closed space uniform, and the amount of material enclosed therein is also uniform, achieving the effect of quantifying the cloth.

In order to further save material costs, the runner is a hollow runner.

In order to further adjust the amount of the feed amount, the runner is connected to the motor via a coupling, and a speed reducer is disposed between the motor and the coupling. The motor and the speed reducer are capable of controlling the speed at which the wheel rotates, thereby achieving control of the amount of material fed by the distributor.

Beneficial effects:

By adopting the distributor of the invention, the distributor and the metering device are combined, the material can be metered at the same time as the cloth, and the uniform arrangement of the separator can reach the quantitative cloth of the material, and the amount of the feeding can be controlled by the control. The moving parts are moved to adjust the speed. In addition, the uniform material of the material can be realized. Since the uniform cloth and the quantitative feeding are realized, the thickness of the material in the next process can be made uniform, which makes the next process better. The processing effect, and the relatively closed space can prevent the flow of air in the logistics channel, avoiding air pollution.
