Abstract

The utility model discloses an automatically elutriation magnetic separator, the basic structure of which includes: an internal cylinder body and an outer cylinder body form a wash-dressing cylinder; the internal cylinder body is connected with a tailings overflow groove the top of which is obliquely arranged; a cylindrical feeder is arranged above the overflowing groove; a circular inflow circle surrounding the wash-dressing cylinder is arranged on the bottom of the wash-dressing cylinder; the internal side of an inflow circle is opened and is connected with an internal cylindrical body; an inlet tube is arranged along the tangent line of the internal cavity of the inlet circle, and the top outlet of the cylindrical body in wash-dressing cylinder is designed to downside truncated cone structure with the gradually increasing cross section. The equipment adopts circular seam type water supply method, thus ensuring the stable water inflow and reducing the fluctuation caused by the hydraulic pressure so as to ensure that the work status of the equipments are kept stable; the level of the overflow area increases to one to two times of the original level, thus enhancing the stability of the level, being beneficial for the layering of the minerals, preventing the fine particle level mineral powder from being over flown and expanding the particle level range of separating mineral powder.

Description

The full-automatic magnetic separator of eluriating

Technical field

The utility model relates to a kind of full-automatic elutriation magnetic separator, and particularly a kind of weak magnetic iron ore magnetic, gravitational separation equipment belong to the mining machinery technical field.

Background technology

The common magnetic plant of present domestic magnetic concentration is drum magnetic separator, sloughing-off tank, magnetic accumulating machine, and magnetic separation post etc., and drum magnetic separator, sloughing-off tank are difficult to obtain high-grade concentrate aborning; The effect aspect selected is obvious in the ore deposit for the magnetic separation post, be applicable to common grade breeze, and to the selected DeGrain of more fine-graded breeze, and when disturbance takes place in hydraulic pressure or ore deposit amount, the spillwag chute instability, former duty is destroyed easily.

Summary of the invention

The utility model technical issues that need to address provide a kind of new automatic elutriation magnetic separator, and existing magnetic separation rod structure is improved, and improve separating effect, enlarge the scope of application.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:

New automatic elutriation magnetic separator, basic structure comprises: in, outer cylinder body is formed the washing tube, inner barrel is communicated with the mine tailing overflow launder that the top is obliquely installed, the overflow launder top is provided with cylindrical dispenser, the dispenser side is communicated with feed pipe, the dispenser bottom is provided with material blanking tube along washing tube axis, in, magnet exciting coil is set between the outer cylinder body, the magnetic separation tube bottom is provided with the concentrate outlet that is communicated with inner barrel, the washing tube bottom is provided with the circular water inlet ring around the washing tube, water inlet ring inside, be communicated with inner barrel, along water inlet ring inner chamber tangential direction water inlet pipe be set, washing tube inner barrel top exit is designed to the inverted round table structure that the cross section increases gradually.

The further improvement of the utility model concrete structure is: washing tube inner barrel top exit area is 1-3 a times of inner barrel sectional area.

The further improvement of the utility model concrete structure is: washing tube middle part to the ring position of intaking, is provided with a cylindrical balance columns coaxial with material blanking tube from the material blanking tube lower end.

The further improvement of the utility model concrete structure is: balance columns diameter and material blanking tube equal diameters.

The further improvement of the utility model concrete structure is: the feed pipe import of dispenser is provided with along dispenser inner chamber tangential direction.

Because the technological progress of having adopted technique scheme, the utility model to obtain is:

This equipment washing tube bottom is provided with the water inlet ring around the washing tube, water inlet ring inside, connection inner barrel, along water inlet ring inner chamber tangential direction water inlet pipe is set, owing to adopt the circular seam type way of supplying water, guarantee that water inlet steadily, reduced the fluctuation that hydraulic pressure produces, made the duty of equipment keep stable; Washing tube inner barrel top exit is designed to the inverted round table structure that the cross section increases gradually, it is original 1-3 times that equipment top overflow area horizontal plane increases, and has improved the stability of liquid level, is beneficial to the layering of mineral, prevent that the fine fraction breeze from being gone out by overflow, thereby enlarge the grade scope of sorting breeze.

Washing tube middle part to the ring position of intaking, is provided with a cylindrical balance columns coaxial with material blanking tube from the material blanking tube lower end, steady ascending current not only, and the while also ties up the blind area that magnetic field acts on, and makes magnetic field more even to the magneticaction power of breeze.

The feed pipe import of dispenser is provided with along dispenser inner chamber tangential direction, makes ore pulp decline direction of rotation opposite with the ascent direction of water, is convenient to being uniformly dispersed of ore pulp, improves the efficiency of separation.
