Description
Technical field
The utility model relates to a kind of flow control device, particularly relates to a kind of flow control device controlled for feeding of roll squeezer.
Background technology
Roll squeezer is as a kind of milling equipment, and the advantage because of its efficient energy-saving is widely used in the grinding system of cement slurry grog, is applied to again in mineral powder grinding system in recent years gradually.But because its roll surface easily damages, maintenance cost is higher, limit the popularization of roll squeezer in ore grinding field.The one of the main reasons that roll surface damages easily causes when being traditional turnover plate type feed arrangement adjust flux size stock column to collapse material.The movement locus of the bottom end points of flow control board when adjust flux size is as Fig. 1 curve C, and when flow control board aperture is minimum, roll surface fallen by the material that collapses distance from turnover panel lower end is greater than 500mm; When flow control board aperture is 50%, this distance is also greater than 210mm.This expects to cause larger impact to roll surface by causing collapsing, thus causes roll surface fatigue rupture.
How to solve the problems of the technologies described above and become these those skilled in the art difficult problem urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is exactly the problem for above-mentioned prior art, provides a kind of, flow control device of extending roll surface service life little to roll surface impulsive force, can effectively solve the problems of the technologies described above.
The purpose of this utility model is realized by following technical proposals:
A kind of flow control device, comprise support, flow control board, the first side link, the second side link, rotating shaft and driving mechanism, described rotating shaft is rack-mount by bearing, driving mechanism drives rotating shaft to rotate, one end of first side link is connected in rotating shaft, the other end and flow control board top hinged, second side link one end and support hinged, the other end and flow control board middle and lower part hinged.
Further, also comprise drive link, described drive link one end is connected in rotating shaft, and the output of the other end and driving mechanism is hinged, and forms the angle of 30 ° ~ 60 ° between this drive link and the first side link.
Further, described driving mechanism is electric pushrod, and handspike bearing fixed by support, jointed shaft bearing on handspike bearing, and the external screw thread screw mandrel of electric pushrod is arranged on bearing block by bearing, internal thread screw mandrel and drive link hinged, electric pushrod is driven by motor.
Further, described motor is provided with the aperture transmitter controlling machine operation.
Further, described flow control board surface is provided with wearing layer.
Owing to have employed said structure, the movement locus of flow control board its underpart end points when doing plane motion is optimized, and the distance change that roll surface fallen by the material fallen from flow control board bottom is comparatively mild, not easily causes the material that collapses.And this apart from time maximum also less than 120mm, avoid the impact that blanking is larger to roll surface.
Compared with prior art, the beneficial effects of the utility model are: in roll squeezer, adopt this flow control device can greatly reduce stock column to collapse material phenomenon, reduce material to the impact of roll surface, thus extend the service life of roll surface.

Fig. 1 is the structural representation of traditional turnover plate type feed arrangement;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation of the utility model for roll squeezer;
Fig. 4 is the perspective view of the utility model using state.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
As shown in Figures 2 to 4, a kind of flow control device, comprise support 1, flow control board 2, first side link 3, second side link 4, rotating shaft 5, drive link 6 and driving mechanism, described rotating shaft 5 is arranged on support 1 by bearing 7, one end of first side link 3 is connected in rotating shaft 5, the other end and flow control board 2 top hinged, second side link 4 one end and support 1 hinged, the other end and flow control board 2 middle and lower part hinged.Described drive link 6 one end is connected in rotating shaft 5, and the output of the other end and driving mechanism is hinged, and forms the angle of 30 ° ~ 60 ° between this drive link 6 and first side link 3.Drive the first side link 3 to move by driving mechanism by drive link 6 and rotating shaft 5, and then drive flow control board 2 to do plane motion.Described first side link 3 and the second side link 4 are provided with 2, the centre position of drive link 6 between 2 the first side links 3.
Described driving mechanism is electric pushrod, support 1 is fixed handspike bearing 8, jointed shaft bearing 9 on handspike bearing 8, bearing block 9 is made to do elevating movement, the external screw thread screw mandrel 10 of electric pushrod is arranged on bearing block 9 by double-direction thrust ball bearing, internal thread screw mandrel 11 end and drive link 6 hinged, electric pushrod is driven by motor 12, motor 12 is fixed on bearing block 9, described motor 12 is provided with the aperture transmitter 13 controlling motor 12 and work.
In use, this flow control device coordinates with the feed pipe 14 of roll squeezer, thus controls discharge quantity.Aperture transmitter 13 controls motor 12 according to the flow control board aperture of setting and works, motor 12 drives the external screw thread screw mandrel 10 of electric pushrod to rotate, and then drive internal thread screw mandrel 11 to do plane motion by worm drive, internal thread screw mandrel 11 drives rotating shaft 5 to rotate by drive link 6, drive flow control board 2 to do plane motion further by the first side link 3, thus realize the adjustment to inlet amount.
The external screw thread screw mandrel 10 of electric pushrod and internal thread screw mandrel 11 are worm drive, and the lead angle of worm drive is less than the equivalent friction angle of screw pair, therefore can realize the self-locking of screw pair, thus when motor 12 quits work, flow control board 2 reliably can keep the aperture set.
Owing to have employed said structure, flow control board 2 movement locus B of its underpart terminal A when doing plane motion is optimized, the movement locus B of flow control board 2 bottom terminal A and the roll surface of roller 15 remain the distance of 5 ~ 120mm, and the change of this distance is mild, make the material fallen from flow control board 2 bottom fall the distance change of roll surface comparatively gently, not easily cause the material that collapses.And this is also no more than 120mm apart from time maximum, avoid the impact that blanking is larger to roll surface.In addition, flow control board 2 surface arranges wearing layer and can greatly extend its service life.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
