The balanced feeding device of a kind of weightlessness
Technical field
The utility model relates to a kind of feeding device, is specifically related to the balanced feeding device of a kind of weightlessness.
Background technology
Weightlessness balance is the key link in raw material mixing system, and it directly has influence on the index such as product quality, efficiency, energy consumption of production.It has adopted the characteristics of discontinuous feed continous way blowing, and for other metering, dosing device, Weightlessness balance is more and more paid close attention in recent years; Because it has possessed the high different advantages of efficiency of stability, accuracy and the dynamic balance of static scale, in metering and batching link, progressively substitute traditional equipment such as belt conveyer scale.For this reason, Chinese patent CN201310059141.6 discloses a kind of electrodynamic type Weightlessness balance, include frame, frame is provided with feeding mechanism from top to bottom successively, metering discharge mechanism and discharging mechanism, feeding mechanism includes feeding cylinder, the feeding cylinder upper end is provided with the flange form charging aperture, be provided with the reciprocating swing type arc batching door coordinated with the bottom discharge mouth in feeding cylinder, the metering discharge mechanism includes weighing hopper, weighing hopper is suspended in the feeding cylinder below by the driver suspension rod, be provided with the reciprocating swing type arc emptying door coordinated with the bottom discharge mouth in weighing hopper, the rotation that discharging mechanism includes discharge bucket arc batching door and arc emptying door is driven by motor respectively, and the upper end of arc batching door and arc emptying door is respectively equipped with switch gate and detects piece, the sensor that the rotating of motor detects piece amplitude of oscillation position by switch gate is controlled.Be provided with the technology of multiple spot detection, sampling, software and hardware filtering on the movement locus of the present invention to bin gate; Weighing hopper has adopted the structure of three sensors, good stability simultaneously.Shortcoming is, structure is too complicated, manufacture and production cost higher.
The utility model content
The purpose of this utility model is to provide a kind of balanced feeding device of weightlessness of new construction, and it is not only simple in structure, and can realize that accurate-metering is reinforced, reduces cost of labor.
For realizing this purpose, the technical solution of the utility model is: the balanced feeding device of a kind of weightlessness, comprise aggregate bin, weighing hopper, described weighing hopper is located at aggregate bin below, and described aggregate bin bottom is provided with a valve, between described aggregate bin and weighing hopper, by a pipeline, communicates, described weighing hopper below is equipped with a LOAD CELLS, described LOAD CELLS, valve are connected with feed regulator respectively, and described feed regulator is according to the numerical value of LOAD CELLS, the switch of by-pass valve control.
As preferably, the charging aperture size of the discharging opening of described aggregate bin and weighing hopper is basic identical, and the discharging opening of described aggregate bin is provided with the arc discharge door, and the charging aperture of described weighing hopper is provided with the arc feeding gate.
As preferably, the rotation of described arc discharge door and arc feeding gate is driven by motor respectively, and described motor is connected with feed regulator.
With respect to prior art, the utility model is by being connected LOAD CELLS, valve respectively with feed regulator, described feed regulator is according to the numerical value of LOAD CELLS, the switch of by-pass valve control, can reach the purpose of dosing like this, improve accuracy and the control accuracy of batch weighing, meet the accurate dosing requirement in producing.Simultaneously simple in structure, easy to implement and popularization.
