Description
Technical Field
The utility model relates to a magnetic separation equipment technical field, in particular to found ring high gradient magnet separator liquid level control system.
Background
The vertical ring high gradient magnetic separator can be used for purifying ferromagnetic substances from ferromagnetic ore pulp and removing ferromagnetic substances from non-ferromagnetic ores. The ore pulp is injected into the magnetic separator through the raw ore pipe, after magnetic separation is carried out in a mineral separation cavity of the magnetic separator, the raw ore is divided into three ways of magnetic separation medium adsorption, middling and tailings to flow out of the magnetic separator, when the liquid level of the mineral separation cavity is stable, the flow of the raw ore is equal to the flow of the tailings, the flow of the middling and the flow of the medium adsorption, and the flow of the middling and the flow of the medium adsorption are far smaller than the flow of the tailings.
The pulp liquid level of the early vertical ring high gradient magnetic separator is manually controlled, under the condition of neglecting middling flow and medium adsorption flow, a related pulp liquid level system is shown in figure 4, raw ore liquid flows into an ore dressing cavity 1 through a raw ore valve 6 and a raw ore pipe 5, a medium rotating along with a vertical ring is in contact with the ore liquid in the ore dressing cavity 1 and adsorbs ferromagnetism, and tailings are discharged out of the magnetic separator through a tailing hopper 2 and a tailing valve 8. The pulsator 18 installed on the tailing bucket 2 applies mechanical pulsation with a certain frequency and stroke to the tailings flowing through the tailing bucket 2, delays the descending speed of the mineral liquid, and promotes the mineral liquid to fully contact with the medium. Adopt the highest liquid level of the restriction ore dressing chamber 1 of the clamp method, set up liquid level case 3 and offer liquid level observation room 19 and overflow room 20 at liquid level case 3, separate with the overflow board between two rooms, 19 liquid level reflection ore dressing chambers 1 of observation room, introduce liquid level case 3 with the mineral liquid through liquid level sampling pipe 4, produce the overflow when the liquid level is higher than on the overflow board along, the mineral liquid overflow goes to the overflow room and leads to the leading-in tailing groove discharge magnet separator of overflow pipe 21.
The liquid level can be adjusted by changing the openness of the raw ore valve and/or the tailing valve to control the flow of the raw ore or the tailing flow, the liquid level of the ore dressing cavity is adjusted by changing the openness of the tailing valve, the openness of the tailing valve is increased when the liquid level is adjusted to be low, and vice versa. Because the magnet separator is bulky, the liquid level case is far away from the tailing valve, needs two operators to cooperate liquid level control, and one operator observes liquid level and liquid level variation trend through the observation room, commands another operator control tailing valve aperture. Under the condition of fixing the opening degree of the raw ore valve and the tailing valve, the flow difference of the raw ore and the tailing can be changed continuously under the influence of various factors, the liquid level of the ore dressing cavity rises and falls along with the flow difference, the liquid level is too low, the liquid level is too high, the liquid level is too low, the separation medium cannot be completely immersed into the ore pulp, and the separation capacity of the magnetic separator is reduced; the liquid level of the ore pulp is too high, so that the ore pulp is easy to overflow and pollute a magnetic separator and a workshop, and the saturated ore pulp of the separation medium is discharged along with tailings without being fully magnetically separated, so that the recovery rate of the ore pulp is reduced.
Patent CN209501948U discloses a found ring high gradient magnet separator liquid level automated inspection adjusting device, adopts the liquid level detection instrument of installing on liquid level fill upper portion to detect the liquid level, sets up the tailing overflow passageway at tailing bottom of the case portion, and the overflow flow is adjusted by electric control valve. Because the controller respectively controls the electric control valve to work in the maximum opening degree state and the minimum opening degree state according to the overhigh liquid level state and the overlow liquid level state detected by the liquid level sensor, the liquid level is limited to fluctuate between overhigh liquid level and overlow liquid level; in addition, the liquid level detection element is in direct contact with the mineral liquid, and mineral particles and oxides thereof are adsorbed on the surface of the element, so that the performance and the service life of the liquid level detection element are influenced.
In a word, a liquid level control system adopted by the vertical ring high gradient magnetic separator can break through the problems that a strong magnetic field generated by an excitation coil magnetizes circuit components and affects the electronic motion deviation on the components and the circuit performance, mineral liquid in a mineral separation cavity is excited by a vertical ring rotating and pulsating mechanism to cause liquid level surging and standing wave, mineral pulp and auxiliary mineral separation medicaments corrode the contacted components, mineral pulp and oxides thereof are accumulated on the surface of the component contacted with the mineral pulp, solid particles in the mineral pulp erode the surface of the component contacted with the mineral pulp to cause abrasion, the electric control characteristic of a flow control execution part is delayed seriously, the mechanical inertia is large and the like, and can realize two functions of automatically stabilizing the liquid level of the magnetic separator and conveniently giving.
