The specific embodiment
For technical characterictic of the present invention, object and effect being had more clearly, understand, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As shown in Fig. 1-Fig. 6, the valve system of bulk material of the present invention comprises body skin 1, flashboard 14, driver train, rotating shaft and rocking arm 11.Body skin 1 is provided with discharging opening, and driver train drives flashboard 14 to rotate by rotating shaft, realizes the switching of discharging opening by the rotation of flashboard 14.Rocking arm 11 is fixedly connected with flashboard 14, fixing by screw 15 in the present embodiment.The two ends of rocking arm 11 are provided with 12, two sleeves 12 of sleeve and are enclosed within respectively two rotating shaft outsides, and rotating shaft can be with moving sleeve 12 to rotate, and sleeve 12 can be connected and fixed by modes such as key 17 are connected with rotating shaft.When driver train drives rotating shaft to rotate, rotating shaft band moving sleeve 12 rotates, thereby drives rocking arm 11 and flashboard 14 to rotate, and realizes the switching of discharging opening.The outside of sleeve 12 is provided with clearance for expansion, needs that can accommodate thermal expansion, clearance for expansion wants to guarantee that sleeve 12 is axially and radially can free expansion, when rotating shaft is arranged on bearing seat 20, between sleeve 12 and bearing seat 20, there is clearance for expansion, when sleeve 12 expands because being heated, can not interfere with driver train, transmission can not be subject to temperatures involved.While damaging because contact with high temperature bulk material for a long time when flashboard 14 or rocking arm 11, flashboard 14 can be taken off very easily or rocking arm 11 is changed.The valve system of bulk material of the present invention can Yin Gaowen and produce transmission failure, and simple in structure, conveniently takes off rocking arm 11 parts such as grade to change, and installation and repairing is convenient.Be understandable that, the valve system of bulk material of the present invention is not only applicable to high-temperature material, is equally applicable to normal temperature material yet.
Further, valve system also comprises baffle plate 16, and baffle plate 16 is fixed in rotating shaft, and baffle plate 16 can be arranged on a side of the axial close flashboard 14 of sleeve 12.Baffle plate 16, for preventing sleeve 12 axial offsets, avoids flashboard 14 to depart from discharging opening.
Further, driver train comprises two oil cylinders 4 and two piston crank mechanisms.Oil cylinder 4 is fixed on cylinder pedestal 5, and cylinder pedestal 5 is fixed on body skin 1 by high temperature bolt 23, and bearing seat 20 is also fixed on body skin 1.Piston crank mechanism is connected with oil cylinder 4, and rotating shaft comprises that two the first rotating shafts 18 and two the second rotating shaft 19, the first rotating shafts 18 are connected with piston crank mechanism with the second rotating shaft 19, the direction of rotation of the first rotating shaft 18 and the second rotating shaft 19.Flashboard 14 is provided with two, and the both sides of a flashboard 14 are connected with two the first rotating shafts 18 by rocking arm 11, and the both sides of another flashboard 14 are connected with two the second rotating shafts 19 by rocking arm 11.The middle part of rocking arm 11 is flat bar, and sleeve 12 is arranged on two ends, and flashboard 14 is fixed on the middle part of rocking arm 11.During oil cylinder 4 action, by piston crank mechanism, drive two pairs of the first rotating shafts 18 and the second rotating shaft 19 to rotate according to different directions, therefore the rotation direction of two flashboards 14 is not identical yet, thereby realizes the switching of discharging opening.By two oil cylinders 4, drive, be not prone to unbalance loading and stuck situation, transmission is more steady.It is synchronous that two oil cylinders 4 are realized rigidity by piston crank mechanism, rocking arm 11 and flashboard 14, and not needing increases extra synchronizer gear, thereby the stressed of single oil cylinder 4 diminished, and more can adapt to the situation of the discontinuity that at high temperature uncertain distortion brings.
Piston crank mechanism comprises the first crank 8, the second crank 9 and connecting rod 10, and connecting rod 10 is connected with the second crank 9 with the first crank 8 respectively by two bearing pins 7, and the piston rod 13 of oil cylinder 4 is connected with the first crank 8 by bearing pin 7.The first crank 8 is fixedly connected with the first rotating shaft 18, and the second crank 9 is fixedly connected with the second rotating shaft 19, in the present embodiment, by key 17, connects.When oil cylinder 4 drives the first crank 8 to rotate, due to the effect of connecting rod 10, the second crank 9 is rotated around contrary direction, therefore the rotation direction of the first rotating shaft 18 and the second rotating shaft 19 is also different, thereby has realized the switching of flashboard 14.
Further, the top of body skin 1 is rectangular cylinder structure, and bottom is divided into cone structure, and top and the bottom are welded into an integral body by rebound.The top of body skin 1 and bottom are respectively equipped with upper flange 26 and upper flange 27, are respectively used to connect the miscellaneous equipment of upper and lower.Inside face at body skin 1 arranges insulating 28, can play heat insulation effect.
Further, valve system of the present invention also comprises inner housing 2, and inner housing 2 is for receiving and guiding bulk material.The top of inner housing 2 is provided with flange 25, and the flange 25 on inner housing 2 is placed on the seam of upper flange 26 of body skin 1, has suitable gap between flange 25 and seam, is convenient to the installation of inner housing 2, is also in order to adapt to the needs of het expansion under high temperature simultaneously.Adopt inner housing 2 and body skin 1 double-decker, good heat-insulation effect, and dismounting is easily, and easy to maintenance.
Further, in inner housing 2 inside, liner plate 3 can also be set, liner plate 3 has wear-resisting, resistant to elevated temperatures performance.Liner plate 3 can be fixed on inner housing 2 by high temperature bolt 23 and hook 24, and 23 of high temperature bolts connect positioning action, and when high temperature bolt 23 lost efficacy, hook 24 can guarantee that liner plate 3 can not come off.Liner plate 3 is set and can protects inner housing 2, reduce the impact of material to inner housing 2.
Further, inner housing 2 is provided with suspension ring 22, and body skin 1 is provided with hanger 21.By suspension ring 22, inner housing 2 can be hung out together with liner plate 3, by hanger 21, body skin 1 can be hung out.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not departing from the scope situation that aim of the present invention and claim protect, also can make a lot of forms, within these all belong to protection of the present invention.
