Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
A kind of embodiment of the bed of material control device in centrifuge of the present invention, comprises pedestal 1, rotates the striker plate and proximity switch 12 that are arranged on pedestal 1.Striker plate forms with the backgauge sheet 3 being arranged on rotating shaft 2 lower end by rotating the rotating shaft 2 be arranged on pedestal 1.Described rotating shaft 2 upper end is fixed with transmission arm 4, the middle part of transmission arm 4 be hinged with push rod 5 and push rod 5 rotates time can promote transmission arm 4 and rotate.Pedestal 1 is hinged with cylinder 6, 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 hinged, proximity switch 3 to be arranged on transmission arm 4 and to coordinate with push rod 5.In order to prevent centrifuge when work, backgauge sheet 3 is caused to locate inaccuracy because of the rotation of rotary drum, described rotating shaft 2 is provided with torsion spring, backgauge sheet 3 is controlled the thickness of feed layer place in setting by torsion spring, if backgauge sheet 3 causes it to depart from desired location (normally the position of backgauge sheet 3 is greater than bed of material setting value) 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, does not then affect the control of the bed of material.In addition, in order to ensure proximity switch be by electricly provide signal to dead electricity, improve the sensitivity of proximity switch, and backgauge sheet can reset, be flexibly connected by bolt 8 and nut 9 between described transmission arm 4 and push rod 5, and position on bolt 8 between transmission arm 4 and push rod 5 be arranged with spring (figure slightly).Certain is by electricly providing signal to dead electricity in order to ensure proximity switch, improve the sensitivity of proximity switch, and backgauge sheet can reset, can also be flexibly connected by bolt 8 and nut 9 between described transmission arm 4 and push rod 5, and bolt 8 be positioned on the position outside transmission arm 4 or outside push rod 5 and be arranged with spring 10---shown in Fig. 1, Fig. 2, Fig. 3.In order to the attractive in appearance and stability of push rod 5 when promoting transmission arm 4, described transmission arm 4 arranges groove, and push rod 5 is positioned at this groove and stretches out with the piston rod 7 of cylinder 6 from one end of groove hinged.For the ease of regulating the distance between backgauge sheet 3 and drum inner wall, described pedestal 1 is evenly equipped with the mounting hole 11 of four circular arcs around its center, described bed of material control device is fixed on rotary drum inside by the combination of the mounting hole 11 on pedestal 1 and bolt.
Another embodiment of the invention is: comprise pedestal, rotate the striker plate and proximity switch that are arranged on pedestal, described proximity switch is arranged on pedestal, pedestal is also hinged with cylinder, striker plate is fixed with transmission arm, one end of transmission arm and the piston rod of cylinder hinged, proximity switch to be positioned at below transmission arm and to match with transmission arm, transmission arm or cylinder is positioned at both hinged places and is provided with mounting hole.This embodiment is fairly simple, roughly the same with the first embodiment, and its difference is that the setting position of proximity switch is different, and do not describe in detail at this, the course of work is also very simple.
Here is the operation principle of the present invention bolt 8 being positioned at sheathed spring 10 on the position outside push rod 5: as shown in Figure 1, Figure 2, Figure 3 shows, the present invention is fixed in the rotary drum of centrifuge, feed system starts charging in 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 to regulate the distance between backgauge sheet 3 one end and drum inner wall to meet bed of material setting value.When the thickness of the bed of material reaches requirement, the end thereof contacts of backgauge sheet 3 is to the bed of material, along with thickening and the rotation of the bed of material, the bed of material can give backgauge sheet 3 one power, and make backgauge sheet 3 along with rotating shaft 22 center rotatings around the shaft, rotating shaft 2 drives transmission arm 4 to rotate, the increase of a distance will be produced between transmission arm 4 and push rod 5, now proximity switch 12 can be electric to dead electricity generation signal from obtaining, and by signal transmission to feed system, stop feeding in raw material to centrifuge; Cylinder 6 also obtains a signal simultaneously, and cylinder 6 is worked, and namely the piston rod of cylinder 6 shrinks, pull push rod 5, push rod 5 promotes transmission arm 4 and rotates, thus by backgauge sheet 3 away from the bed of material, in the process, transmission arm 4 and push rod 5 reset under the effect of bolt 8, nut 9 and spring 10.If need again to feed in raw material to the bed of material, the piston rod 7 of cylinder 6 so can be driven to stretch out, thus make backgauge sheet 3 in running order.
Advantage of the present invention is: 1, spring life is long, and during common bed of material control device reset mode, spring is always at deformation state, and the spring in the present invention is short time set.2, working stability, the common bed of material control device arm of force relatively short (active force is little), and the arm of force of the present invention is long, also has quadric chain action, working stability, error-free motion.3, be active in one's movements, proximity switch mounting distance is than the revolution distance of common bed of material control device; Proximity switch is from electricly providing signal to dead electricity, and common bed of material control device is from dead electricity to obtaining the electric signal that provides, and comparatively speaking, it is sensitiveer that the former provides signal.
