Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
embodiment 1
As Figure 1-3, a kind of central cooler containment type of the present invention mechanical sealing system comprises: be arranged on circular cooler trolley and triangular beam 10 and seal ground way 30 below breast board 11, be arranged on the floating slideway 40 of air outlet upper edge, air channel 20.Ground way 30 comprises internal fixtion slideway 30 ' and extenal fixation slideway 30 " that are separately positioned on central cooler inner ring and outer shroud; Described floating slideway comprises interior floating slideway 40 ' and outer floating slideway 40 " that are separately positioned on central cooler inner ring and outer shroud.Floating slideway 40 both sides are provided with the stopping means 50 for limiting the left and right displacement change in the horizontal direction of described floating friction plate, and stopping means 50 is for being arranged on the side plate of floating slideway both sides.In addition, stopping means 50 can also for being arranged on the block or column etc. of floating slideway both sides.Ground way 30 is made up of several ground way plates.
The slideway 40 that floats comprises by some floating friction plates 41, containment type sealing plate 45 and for the friction plate 41 that floats described in jack-up, and makes the spring 48 of floating friction plate 41 and described ground way 30 close sliding contact.Ground way and described floating friction plate are corresponding up and down to be arranged, floating friction plate 41 under the effect of spring 48 with ground way 30 close sliding contact.
Containment type sealing plate 45 upper end is fastened on the side of the side, air channel of floating friction plate 41, and lower end is close to the medial surface of duct outlet, for sealing up floating slideway 40, prevents the cold wind in air channel from overflowing from floating slideway.Containment type sealing plate 45 is sheet metal, and its lower end is not fixed, under the pressure effect of cold wind, sealing plate lower end tightly with the medial surface close contact of duct outlet.Containment type sealing plate is made up of some blocks of sheet metals, and adjacent sheet metal is laid staggeredly, and alternating share width is 10 to 50 millimeters, and then guarantees the sealing between floating friction plate and air channel.
In air channel blast effect under, inside the lower end of containment type sealing plate 45 and duct outlet, close contact realizes sliding friction and seals.The cold air be blown into by air blast almost can the cooling of sintering deposit all on chassis, improves the cooling effect of central cooler.And avoid and to cause owing to leaking out a large amount of dust to be blown to contamination phenomenon in air.
Spring 48 is helical spring, work pressured state.In addition, spring can also be flat spring or rubber spring etc.
The float two ends of friction plate 41 are all provided with guiding surface (not shown), so avoid floating described in described chassis rotary course friction plate and ground way stuck; The float two ends of friction plate are provided with the boss and groove structure that are mutually sealed and matched, adjacent two pieces of floating friction plates by boss together with groove compact siro spinning technology.
The slideway 40 that floats also comprises the adjusting device 49 for the amount of force of regulating spring 48, and adjusting device 49 can oscilaltion be arranged on the mounting base on duct outlet upper edge, and spring 48 is fixed in adjusting device 49.Adjusting device 49 is provided with adjusting screw(rod) for lower end, mounting base is provided with the screwed hole matched with adjusting screw(rod), by rotating adjusting screw(rod) thus the height of elevation and subsidence regulating device 49, and then regulate the pressure size of floating between slideway and ground way, and then when ensureing sealing effectiveness, reduce frictional force.
Central cooler containment type mechanical sealing system also comprises and supports chassis when wheel topples to side for falling at chassis and send support and the warning system 60 of warning; Support and warning system 60 are arranged on below duct outlet upper edge, described sealing breast board and the outside of floating slideway.Support and warning system 60 comprise several for supporting the carrying roller 61 of chassis and the pressure sensor 65 for reporting to the police; Pressure sensor 65 is arranged on the side of carrying roller 61; Chassis falls wheel when toppling to side, and ground way falls and carrying roller and pressure sensor contacts, and when pressure sensor institute measuring pressure exceedes setting value, then pressure sensor gives the alarm.
When central cooler works, ground way follows chassis and triangular beam moves in a circle in orbit, due to floating friction plate under the pressure of the spring with ground way close contact, rely on sliding friction each other to realize sealing.Under the prerequisite ensureing floating friction plate, ground way sealing effectiveness, the frictional force both as far as possible reducing and service wear, the present invention is provided with the adjusting device of the amount of force for regulating spring 48; The height of spring is changed by rotating adjustment screw rod, thus realize the change of spring force, reach the pressure controlled between ground way and floating friction plate, realize frictional force adjustable, ensure that the sealing effectiveness after Long-Time Service and reduce the resistance of central cooler operation.
embodiment 2
The present embodiment is substantially the same manner as Example 1, and difference is:
As shown in Figure 4, containment type sealing plate 45 ' is flexible thin, and the medial surface of its lower end and air channel 20 air outlet is fixedly installed, and when floating slideway 40 fluctuates, in the middle of containment type sealing plate 45 ', plastic deformation occurs.
embodiment 3
The present embodiment is substantially the same manner as Example 2, and as illustrated in Figures 5 and 6, difference is:
1) support and warning system 60 are that several are for supporting riser or column 61 ' and limit switch 65 ' for reporting to the police of chassis.When de-wheel occurs chassis, the fixed glides of ground way falls, and column or riser 61 ' support chassis, avoids chassis that more serious overturning occurs and damages ground way and floating slideway even completely.The ground way simultaneously fallen touches limit switch 65 ', and support and warning system then give the alarm, or directly stops remaining in operation of circular cooler trolley, thus proterctive equipment is not damaged in time.
2)
float the floating friction plate 41 of slideway 40 by leverage 80 jack-up, leverage 80 comprise weight 81, by the weight transfer of weight to floating friction plate by the connecting rod 85 of floating friction plate jack-up; Connecting rod 85 in the present embodiment is two, is applied to all the time on floating friction plate by the gravity of weight 81 by lever principle, and make floating friction plate all the time close contact fixed glides.Adjusting device is weight, then can adjust the frictional force between described floating slideway and ground way by the weight increasing and decreasing weight 81.
In addition, weight 81 can also replace with extension spring, by connecting rod 85, the pulling force of extension spring is converted to the pressure being applied to floating friction plate, then can realize the frictional force size between ground way and floating slideway by the tensile elongation of adjustment extension spring.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various improvement or change.Within the spirit and principles in the present invention all, any amendment made, equivalent to substitute, improvement etc., all should be included within protection scope of the present invention.
