Description

Novel deslagging system

Technical Field

The utility model relates to a mine deslagging equipment technical field, concretely relates to novel deslagging system.

Background

Because of the shortage of water resources in mining units, most of water among production procedures of mineral dressing operation adopts underground water and overflow water of a thickener, and the water is recycled after precipitation. This water is widely used in belt sweepers to remove slag from the conveyor belt, ensuring proper operation. However, the water often contains a large amount of impurities such as floaters, slag impurities and the like, so that the water outlet of the sweeper is easy to be blocked, the conveyor belt cannot be thoroughly cleaned, and the service life of equipment is prolonged, and the production cost is increased.

In order to reduce sundries in mine water, the traditional treatment method is to filter the mine water by adopting a slag remover and then convey the filtered mine water to a sweeper, wherein a filter element device in the slag remover mainly uses stones, steel balls and the like as filler materials. However, the filter element is often blocked in the filtering process by using the slag remover, so that the pressure of the water outlet is greatly reduced, and the normal operation of the cleaner cannot be ensured. Therefore, after the slag remover is used for a period of time, the filter element is usually cleaned in a backwashing mode, but a large amount of impurities still remain in gaps of filter element filler due to limited space in the filter element, so that the filtering effect of the filter element is reduced, and the pressure of a water outlet is reduced. If the backwashing effect is improved by increasing the backwashing water pressure, the equipment cost is greatly increased; if a manual cleaning mode is adopted, the operation is complex, and the cleaning efficiency is low.

In order to solve the problem, the utility model with the application number of CN201520501308.4 discloses a floating ball slag remover, which belongs to the field of mine slag removing equipment and comprises a cylinder body, a primary slag removing filter element, a secondary slag removing filter element, a tertiary slag removing filter element and a backwashing device. The filter element is internally provided with a floating ball with the density lower than that of water, and the three filter elements are sequentially arranged in the cylinder body from bottom to top. The backwashing device mainly comprises backwashing water ports facing each filter element. When filtering water, the floating ball floats upwards, and the water is filtered by utilizing the gaps among the balls; in the backwashing process, the floating ball and sundries sink to the bottom of the filter element together, the backwashing space is large, and the floating ball can move under the backwashing acting force, so that the sundries in the filter element can be effectively removed, and the filter element has the advantages of simple structure, convenience in operation, good deslagging effect, high efficiency and capability of being cleaned automatically.

The novel slag removal and back flushing problems are solved from a technical thought, but the following defects still exist:

1. when in filtering, the floating ball can float upwards under the action of buoyancy and is filtered by the clearance of the floating ball, however, under the impact of water flow, the clearance of the floating ball is easy to be enlarged, so that the filtering effect is poor, and a large amount of sundries still pass through the clearance;

2. in the back flushing process, the floating balls sink to the bottom together with sundries, and as water flow passes through quickly in the flushing process, the floating balls cannot adjust gaps between the floating balls by means of buoyancy, so that impurities are restrained by the floating balls, and the deslagging effect is reduced.
