Description
Technical field
The utility model relates to the unloading valve that the ash discharge of a kind of industrial furnace dust collection device is used.
Background technology
At present, in dust collection device employed unloading valve mainly by valve body, be installed in star-wheel in the valve body, formed by reductor and electrical motor that coupler links with it at spindle nose one end of star-wheel.Because the unloading valve of this kind structure adopts the mode of the horizontal use of vertical type motor mostly, on same axis, produce many fulcrums supports and cause additional dynamic load, cause the early failure of mechanical part (as bearing, reductor, electrical motor) easily.Two portions of being association of activity and inertia in the shaft place of valve body star-wheel adopt common gland-type hermetically-sealed construction, and sealing effectiveness is relatively poor, very easily wear ash and grind bearing, reduce service life.In addition; because this equipment is mounted in working environment and the very abominable place of operating condition; in case star-wheel is difficult to be found by the people by the stuck back of foreign matter; if meet the malfunctioning situation of electric protection again; reductor and electrical motor will be burnt because of overload, also can cause whole production line to stop production when serious.
Summary of the invention
The purpose of this utility model is to provide a kind of leak tightness that can improve two portions of being association of activity and inertia in shaft place of system's transmission accuracy and star-wheel; and have an automatic deloading function decide the moment of torsion star-shaped ash unloading valve, to be implemented in the purpose that the malfunctioning situation of electric protection is issued to protection reductor and electrical motor.
Another purpose of the present utility model be to provide a kind of can be when overload auto alarm and parking decide the moment of torsion star-shaped ash unloading valve.
Another purpose of the present utility model be to provide a kind of when star-wheel is stuck, be convenient to take out foreign matter decide the moment of torsion star-shaped ash unloading valve.
The purpose of this utility model is to realize like this, should decide the moment of torsion star-shaped ash unloading valve mainly by valve body, be installed in the valve body star-wheel and and the joining reductor of spindle nose one end and the electrical motor of star-wheel formed, wherein reductor and electrical motor are horizontal type structure, be fixed in the position of star-wheel side, a drive sprocket is installed on its spindle nose, spindle nose one end at star-wheel is installed a driven sprocket that has power-transfer clutch, links by a closed chain and active and driven sprocket.
Power-transfer clutch of the present utility model is made up of driven sprocket, the holddown spring that cliding friction is bored, close outside slip dynamic friction is bored that is installed in the driven sprocket both sides and spring compressor and jam nut.
What the utility model adopted is horizontal reductor and electrical motor, by the linked transmission mode power is delivered on the spider gear shaft, overcome because conventional direct-connection type vertical electrical motor crouches and supported the problem of the static indeterminacy live load that produces with the same axially upward many fulcrums that bring, improved the service life of bearing and reductor electrical motor, problems such as reductor leakage of oil have been solved, improve the stress condition of main shaft, improved the transmission accuracy of system.In addition; because the driven sprocket on the spider gear shaft is fixed by power-transfer clutch; load capacity on its spider gear shaft and power-transfer clutch to compress degree relevant; after in case clutch resetting is good; the magnitude of load of crossing of electrical motor has just been fixed; when load during greater than the load of electrical motor, electrical motor will drive sprocket wheel idle running, even also can not burn reductor and electrical motor when electric protection is malfunctioning like this.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.As shown in Figure 1, 2, 3, of the present utility model decide the moment of torsion star-shaped ash unloading valve mainly by valve body 1, be installed in the star-wheel 2 in the valve body 1 and formed with the joining reductor of spindle nose one end and the electrical motor 3 of star-wheel.Reductor and electrical motor 3 are horizontal type structure, be fixed in the position of valve body 1 side, a drive sprocket 4 is installed on the reductor spindle nose, a driven sprocket 6 that has power-transfer clutch 5 is installed, link by a closed chain 7 and active and driven sprocket at spindle nose one end of star-wheel.As shown in Figure 4, the star-wheel two ends have cover 21 in the concave type, two end cap 8 inboards of valve body are provided with convex type sealing wheel hub 81, spider gear shaft 9 passes wheel hub and wheel hub is bumped in the spill of star-wheel and overlaps 21, in wheel hub, leave certain clearance with the junction of spider gear shaft, fair gland packing 10 is filled out in the inside, compresses by gland 11 at last, and bearing 12 is installed in the outside of end cap 8.When material penetrates slit between the convex-concave axle sleeve 21,81, the pressure of material reduces gradually, simultaneously be provided with spiral grooves on sealing wheel hub 81 surfaces of projection, further stoped penetrating of material, can realize the composite seal between spider gear shaft 9 and the end cap 8 like this, solve the problem of wearing ash herein effectively.
Shown in Fig. 4,5, the power-transfer clutch 5 in the utility model by driven sprocket 6, be installed in the driven sprocket both sides cliding friction awl 51, formed near the holddown spring 52 of outside slip dynamic friction awl and spring compressor 53 and jam nut.In addition, an overload cam dial 54 is installed between outside slip dynamic friction awl 51 and holddown spring 52, an overload actr 13 is installed in the outside of driven sprocket 6, a travel switch 14 that is triggered by overload actr 13 is installed on the chain wheel cover, and the trip switch 14 is interlocked mutually with the warning device of electrical motor and control cabin respectively.Spring column pin during installation in the overload actr 13 faces the depression of overload cam 54, guarantees that the interlock driving lever on the overload actr 13 does not contact with travel switch 14 when normal operation.Its principle of work is to decide the load-carrying capacity of driven sprocket 6 by the thrust of adjusting spring 52.Two cliding frictions awl 51 clamps driven sprocket 6 after strengthening spring pressure, driven sprocket 6 begins to drag spider gear shaft 9 rotations under the effect of chain 7 tractive forces, after meeting the stuck spider gear shaft of foreign matter in the valve body, driven sprocket 6 is thrown off with the sliding type cone of friction 51 of both sides or generation relative motion (promptly the friction awl does not change), force the overload actr 13 that is located on the driven sprocket 6 to leave the depression of overload cam dial 54 and rotate along its protruding outward flange, the machinery that transships simultaneously on the actr 13 is opened, touching travel switch 14 makes electrical motor 3 outage parkings and sends alerting signal in addition to control cabin, when star-wheel 2 is stuck, for the ease of taking out foreign matter, the utility model is provided with a hand hole door 15 in side of valve body, and is provided with O-ring seal on door.
