A kind of pulsating water current generating system
Technical field
The utility model relates to the auxiliary generation device of a kind of pulsation, relates to a kind of pulsating water current generating system that makes current produce pulsation specifically.This generating means can be used for cooperating sorting mineral equipment to realize efficient, the high accuracy sorting of mineral.
Background technology
Begin to utilize animal skin to eluriate the principle that mineral have just begun to utilize the pulsation sorting from people.Occurred first before more than 400 years and utilize jigging machine that pulsation comes sorting mined material till now, the sorting of pulsation jigging accounts for critical role in the ore dressing industry always, and its grading principle is exactly to utilize layering that fluctuating flow realizes mineral and separate.
The producing method of fluctuating flow is varied.The fluctuating flow producing method mainly contains at present: utilize reciprocating motion of the pistons to produce fluctuating flow; Utilize eccentric ratio to drive barrier film and produce fluctuating flow; Make current produce pulsation by compressed air; Utilize machinery or hydraulic-driven sieve plate to move reciprocatingly and realize pulsation sorting etc.Though many new pulse generating devices are also arranged, these devices all are to pass through to change connecting rod on above several modes basis, and parameters such as transmission speed, frequency realize.Though these pulse generating devices are fairly perfect, there is the device structure complexity mostly, relatively heavier, underaction is if defective such as cost prohibitive when using on than skinny device.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of screening installation of can assisting to realize efficient, high accuracy sorting, and can improve the pulsating water current generating system of the concentrate rate of recovery at existing weak point in the prior art.
The purpose of this utility model can realize by following technique measures:
Pulsating water current generating system of the present utility model comprises a frequency conversion voltage adjusting water pump that is used to provide the water source, and be successively set on flowmeter, ball valve, the magnetic valve on the supply channel that is connected with the frequency conversion voltage adjusting pump outlet and be installed in the nozzle at supply channel delivery port place; The control signal input of described magnetic valve inserts the signal output part of frequency generator by controller.
Controller described in the utility model is an electromagnetic relay; Described frequency generator is made up of the time relay of two parallel connections.Certainly realize the fluctuating flow except utilizing time/electromagnetic relay at the utility model, also can adopt other known suitable device to realize fluctuating flow according to this principle.
The model of the frequency conversion voltage adjusting water pump described in the utility model is the BOZ clarified water pump; The model of described magnetic valve is LQ10-1; The model of described electromagnetic relay is JTX-2C; The model of the described time relay is JS14P.
Operation principle of the present utility model is as follows:
The utility model is by the time interval regulating frequency of the time relay of adjusting component frequency generator, frequency generator is controlled the unlatching of magnetic valve with the frequency signal of output by the electromagnetic relay of the controller of formation, thereby realizes producing the fluctuating flow purpose.
The flowmeter, the ball valve that are arranged on the supply channel described in the utility model are mainly used in the size of controlling confluent.
The beneficial effects of the utility model are as follows:
The utility model not only has simple in structure compared to existing technology, and devices such as mini-plant are easy to combination, and is convenient, flexible, the low and advantage that is easy to realize of cost; Main is conveniently to regulate stroke and jig frequency, in time adapts to changeable operating mode, can assist screening installation to realize efficient, high accuracy sorting, and can improve the concentrate rate of recovery.
