Description
Technical field
The present invention relates to a kind of cement equipment, especially a kind of grate-cooler shedding mechanism specifically a kind ofly is discharged into load-transfer device with cooled grog from grate and carries out broken two plate constant pressure type wind-locking discharge valves for follow-up disintegrating apparatus.
Background technology
as everyone knows, need to be discharged into load-transfer device from grate after cement clinker is cooling and carry out fragmentation for follow-up equipment, owing to can taking away a large amount of heats in discharge process, be unfavorable for the energy recycling, and cause a large amount of energy dissipations, therefore, people wish namely may reduce when discharge valve is opened the chance of grate and outside air exchange, therefore, method commonly used is to carry out the secondary discharging at present, namely first grog is discharged in barrel, then close discharge valve, the lower valve plate of opening again the barrel bottom after closing Deng discharge valve falls on the load-transfer device of bottom grog, open simultaneously in order to prevent two valve plates, people have designed various together with mechanism, but the common complex structure that exists of these mechanisms, control difficulty large, the problem of poor reliability.
Summary of the invention
The objective of the invention is for the ubiquitous complex structure of double valve plates discharge valve that uses in grate-cooler grog discharge process, the problem of poor reliability designs two plate constant pressure type wind-locking discharge valves a kind of simple in structure, safe and reliable.
Technical scheme of the present invention is:
a kind of pair of plate constant pressure type wind-locking discharge valve, comprise valve plate 1 and lower valve plate 8, it is characterized in that described upper valve plate 1 hinge is contained on an end of upper valve rod 2, the other end of upper valve rod 2 and upper axle 9 are fixedly linked, described lower valve plate 8 hinges are contained on an end of lower valve rod 10, the other end of lower valve rod 10 and lower shaft 11 are fixedly linked, be fixedly connected with upper pendulum bar 4 on upper axle 9, be fixedly connected with draft link 6 on lower shaft 11, be connected by interlock spring 3 between upper pendulum bar 6 and draft link 6, between upper axle 9 and lower shaft 11, axle drive shaft 12 is installed, crank 5 is installed on axle drive shaft 12, crank 5 is driven upper pendulum bar 4 or draft link 6 under the drive of axle drive shaft 12, thereby alternately close lower valve plate 8 and upper valve plate 1 when alternately opening valve plate 1 and lower valve plate 8.
Described axle drive shaft 12 directly is connected with the output shaft of drive motor or drop-gear box.
Described upper valve rod 2 and lower valve rod 10 are arranged in discharge valve housing 7, the peaceful draft link 6 of described upper pendulum bar 4 all is positioned at outside described discharge valve housing 7, described interlock spring 3, axle drive shaft 12 and crank 5 all are positioned at outside described discharge valve housing 7, and the two supports of described upper axle 9 and lower shaft 11 is on discharge valve housing 7.
Beneficial effect of the present invention:
The present invention is simple in structure, all adopts piston crank mechanism to control, and have together with and interlock function, all actuators all are positioned at the valve body outside except the upper lower valve rod that must be connected with valve plate, operation, easy to maintenance.
The present invention adopts interlinked mechanism, can not produce misoperation, can guarantee to open when upper lower valve plate is different, has an energy-saving effect obvious, the advantage that loss of pressure is little.
Description of drawings
Fig. 1 is that upper valve plate of the present invention is opened, the structural representation when lower valve plate is closed.
Fig. 2 is that upper valve plate of the present invention is closed, the structural representation when lower valve plate is opened.
Fig. 3 is that upper valve plate of the present invention is opened, the discharging view when lower valve plate is closed.
Fig. 4 is that upper valve plate of the present invention is closed, the discharging view when lower valve plate is opened.
The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Fig. 1-4.
a kind of pair of plate constant pressure type wind-locking discharge valve, comprise valve plate 1, lower valve plate 8 and housing 7, there is corresponding adapter plate at housing 7 upper-lower position places angle mount respectively, have on adapter plate with described on the through hole that matches of valve plate 1 and lower valve 8, the size of through hole should be less than the size of upper valve plate 1 and lower valve plate 8, to prevent that upper valve plate and lower valve plate from passing through hole, as Fig. 3, shown in 4, upper valve plate 1 hinge is contained on an end of upper valve rod 2, the other end of upper valve rod 2 and upper axle 9 are fixedly linked, upper axle 9 passes housing 7, the two ends of upper axle 9 are bearing in respectively in the bearing that is arranged on housing 7, one end of upper axle 9 stretches out housing 7 end outer and upper pendulum bar 4 and is fixedly linked, described lower valve plate 8 hinges are contained on an end of lower valve rod 10, the other end of lower valve rod 10 and lower shaft 11 are fixedly linked, the lower shaft 11 also empty housing 7 of crossing is installed, the two ends of lower shaft 11 are bearing in respectively in the bearing that is arranged on housing 7, one end of lower shaft 11 stretches out outside housing 7 and is fixedly connected with draft link 6, be connected by interlock spring 3 between upper pendulum bar 6 and draft link 6 end outside housing 7, outside housing 7, between upper axle 9 and lower shaft 11, axle drive shaft 12 is installed, crank 5(is installed on axle drive shaft 12 also to be positioned at outside housing 7), axle drive shaft 12 can directly be connected with drive motor, also can drive by drop-gear box, crank 5 is driven upper pendulum bar 4 or draft link 6 under the drive of axle drive shaft 12, thereby alternately close lower valve plate 8 and upper valve plate 1 when alternately opening valve plate 1 and lower valve plate 8.when driving cranks 5, axle drive shaft 12 turns to when contacting with upper pendulum bar 4, upper pendulum bar 4 rotates counterclockwise, thereby in drive, axle rotates counterclockwise, upper axle drives upper valve rod and rotates counterclockwise, upper valve plate is left behind from the through hole on adapter plate, fall for material, under the pulling of interlock spring 3, draft link 6 is subject to forcing the effect of its power that rotates clockwise, lower valve plate is adjacent on lower fixedly swash plate firmly as figure Fig. 1, shown in 3, when crank 5 is rotated further when offseting with draft link 6, lower valve plate 8 is opened, upper valve plate 1 is in closed condition, as Fig. 2, shown in 4.Therefore, only need the rotating speed of control axle drive shaft can realize alternately accurately opening of valve plate 1 and lower valve plate 8.
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
