The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
A kind of embodiment of the bed of material control device in the centrifuge of the present invention comprises pedestal 1, rotates the striker plate be arranged on the pedestal 1 and near switch 12.Striker plate is made up of with the backgauge sheet 3 that is arranged on rotating shaft 2 lower ends the rotating shaft 2 that rotation is arranged on the pedestal 1.Fixedly there is transmission arm 4 described rotating shaft 2 upper ends, and the middle part of transmission arm 4 can promote transmission arm 4 when being hinged with push rod 5 and push rod 5 rotations and rotate.Be hinged with cylinder 6 on the pedestal 1, normally simplified the and pedestal 1 of cylinder 6 is hinged.One end of push rod 5 and the piston rod 7 of cylinder 6 are hinged, are arranged on the transmission arm 4 and with push rod 5 near switch 3 to cooperate.In order to prevent that centrifuge is in work, cause backgauge sheet 3 location inaccuracy because of the rotation of rotary drum, described rotating shaft 2 is provided with torsion spring, the thickness of feed layer place that torsion spring is being set 3 controls of backgauge sheet, if backgauge sheet 3 causes it to depart from desired location (normally the position of backgauge sheet 3 sets value greater than the bed of material) because of the rotation of rotary drum, backgauge sheet 3 can reset under the effect of torsion spring, if backgauge sheet 3 is mobile in the other direction, then the control to the bed of material does not influence.In addition, in order to ensure near switch be by electricly provide signal to dead electricity, improve the sensitivity near switch, and the backgauge sheet can reset, flexibly connect by bolt 8 and nut 9 between described transmission arm 4 and the push rod 5, and the position between transmission arm 4 and push rod 5 is arranged with spring (figure slightly) on the bolt 8.Certainly in order to ensure near switch be by electricly provide signal to dead electricity, improve the sensitivity near switch, and the backgauge sheet can reset, can also be to flexibly connect by bolt 8 and nut 9 between described transmission arm 4 and the push rod 5, and be positioned on the bolt 8 on the position in transmission arm 4 outsides or push rod 5 outsides and be arranged with spring 10---Fig. 1, Fig. 2, shown in Figure 3.For attractive in appearance and push rod 5 stability when promoting transmission arm 4, on the described transmission arm 4 groove is set, push rod 5 is positioned at this groove and stretches out with the piston rod 7 of cylinder 6 hinged from an end of groove.For the ease of regulating the distance between backgauge sheet 3 and the drum inner wall, be evenly equipped with the mounting hole 11 of four circular arcs on the described pedestal 1 around its center, described bed of material control device is fixed on rotary drum inside by the combination of the mounting hole 11 on the pedestal 1 and bolt.
Another embodiment of the invention is: comprise pedestal, rotate the striker plate be arranged on the pedestal and near switch, describedly be arranged on the pedestal near switch, also be hinged with cylinder on the pedestal, transmission arm is fixedly arranged on the striker plate, one end of transmission arm and the piston rod of cylinder are hinged, be positioned at transmission arm below and match with transmission arm near switch, be positioned at both hinged places on transmission arm or the cylinder and be provided with mounting hole.This embodiment is fairly simple, and is roughly the same with first kind of embodiment, its difference be near switch the position difference is set, do not describe in detail at this, the course of work is also very simple.
Be the operation principle of the present invention that is positioned at sheathed spring 10 on the position in push rod 5 outsides on the bolt 8 below: as Fig. 1, Fig. 2, shown in Figure 3, the present invention is fixed in the rotary drum of centrifuge, feed system begins charging in the rotary drum, rotary drum is in rotary state simultaneously, one end of backgauge sheet 3 is near drum inner wall, according to the requirement of the bed of material, make the distance of regulating between backgauge sheet 3 one ends and the drum inner wall meet bed of material setting value.When the thickness of the bed of material reaches requirement, one termination of backgauge sheet 3 contacts the bed of material, thickening and rotation along with the bed of material, the bed of material can be given 3 one power of backgauge sheet, makes backgauge sheet 3 along with rotating shaft 2 is rotated at 2 centers around the shaft, and rotating shaft 2 drives transmission arm 4 and rotates, the increase that will produce a distance between transmission arm 4 and the push rod 5, this moment can be electric to dead electricity generation signal from getting near switch 12, and signal is passed to feed system, stops centrifuge being fed in raw material; Cylinder 6 also obtains a signal simultaneously, makes cylinder 6 work, and namely the piston rod of cylinder 6 shrinks, pulling push rod 5, push rod 5 promote transmission arms 4 and rotate, thus with backgauge sheet 3 away from the bed of material, in this process, transmission arm 4 and push rod 5 reset under the effect of bolt 8, nut 9 and spring 10.Reinforced again to the bed of material if desired, the piston rod 7 that can drive cylinder 6 so stretches out, thereby makes that backgauge sheet 3 is in running order.
Advantage of the present invention is: 1, spring life is long, and spring is always at deformation state during common bed of material control device reset mode, and the spring among the present invention is short time set.2, working stability, the common bed of material control device arm of force are relatively lacked (active force is little), and the arm of force of the present invention is long, also have the quadric chain action, working stability, no misoperation.3, be active in one's movements, near the revolution distance of switch mounting distance than common bed of material control device; Near switch be from electricly provide signal to dead electricity, and common bed of material control device be from dead electricity to the electric signal that provides, comparatively speaking, it is relatively sensitiveer that the former provides signal.
