Abstract
The utility model discloses a safe alarming coal feeding device. The utility model is characterized in that a chain wheel 1 of a drum-type coal feeder is fixed on a slide disc 4 of a ball safety clutch, and a drum rotating shaft 19 is fixed on a fixed disc 5 of the clutch. Therefore, the utility model solves the problem of shaft breaking caused by drum blocking in the working process of the coal feeding device.
Description
The utility model relates to a kind ofly provides the just commentaries on classics chain-grate boiler coal feeder of coal to just changeing chain-grate boiler, particularly relates to the coal feeder that this kind has safety, alarm and protection measure.
Chinese patent CN21250734 Chinese patent discloses a kind of grate firing boiler coal feeder, coal breakage bucket wherein, feeding-coal bucket and branch coal bunker are combined as a whole, divide in the coal bunker sieve is set, the coal that feeder from feeding-coal bucket drops in the branch coal bunker makes coal cinder separate with coal dust through this sieve, and make it drop on clockwise the mistake on the pot chain according to certain requirement according to the difference of coal weight size, form gas permeability coal seam preferably, solving is just changeing that the ubiquitous coal adaptability of chain-grate boiler is poor, efficiency of combustion is low, problems such as undercapacity.
This coal feeder adopts the drum-type feeder generally speaking, and the sprocket wheel on the roller shaft drives cylinder and rotates under motor-driven, thereby makes coal thereon loose.But because the gap between cylinder and the feeding-coal bucket is less, and immobilizes, occur exceeding standard in coal coal cinder or foreign matter enter feeding-coal bucket, or the coal in the feeding-coal bucket accumulates excessively, and cylinder can be stuck and can not rotate, and causes the fracture of roller shaft.
Goal of the invention of the present utility model is to provide a kind of can overcome the defective that prior art exists, and when the generation cylinder is stuck, can avoid taking place just commentaries on classics chain-grate boiler safety, the warning coal feeder of rotating shaft fracture.
Goal of the invention of the present utility model is achieved in that on the prior art basis, a kind of ball overload-release clutch of design between sprocket wheel and roller shaft.The concrete structure of this clutch is: sprocket wheel in the end face of slider disc, is shaped on the ball pod of some, the radius r of ball pod by the slider disc that is bolted to of gland on the circumference that with R is radius
1Less than the spherical radius r of ball, make pod on the slider disc smaller part ball of can only packing into; On the end face of the coaxial fixed disk that is oppositely arranged of slider disc, same is to be shaped on ball with the slider disc equal number on the circumference of radius to hold and need the radius r of this pod with r
2Greater than the spherical radius r of ball, the hole depth h of pod is less than ball bulb diameter 2r, greater than spherical radius r
0, the pod hole on the fixed disk is sealed by baffle ring, and baffle ring is by being with the bolt of helical spring, being fixed on the fixed disk, and fixed disk connects as one by axle coupling and roller shaft.6～12 pods preferably are set on fixed disk and the slider disc.
Because the utility model has adopted the clutch of this structure, during operate as normal,
Because the thrust of spring is between slider disc and the fixed disk roller, the moment of torsion that sprocket wheel transmits passes through ball, fixed disk, thereby passes to the rotating shaft of cylinder; When cylinder is stuck, when moment of torsion surpasses allowable value, the axial thrust load compression that spring is exaggerated, fixed disk is moved right, and roller is entered in the pod of fixed disk fully, this moment, sprocket wheel drove slider disc, fixed disk stops operating, and has avoided the generation of roller shaft phenomenon of rupture.Recover normal when load, can transmit moment of torsion again again.In addition, a siren can be set on this device, its key switch can be connected with the baffle ring contact, and when cylinder was stuck, the baffle ring lateral displacement can trigger alarm equipment alarm.
Below with reference to accompanying drawing the utility model is done and to be described in further detail.
Fig. 1 is safety, warning coal feeder structural representation;
Fig. 2 is the structural representation of ball overload-release clutch.
Referring to Fig. 1, Fig. 2.The coal breakage bucket (16) of coal feeder, feeding-coal bucket (12) and branch coal bunker (13) are integrated, wherein divide an individual layer composite screen (14) is set in the coal bunker (13), it acutangulates with positive converter row's (15) trend, its rear end is fixedly mounted on the back rest (18), drum-type feeder (17) in the feeding-coal bucket (12) is under the motor transmission, driving roller shaft (19) by sprocket wheel (1) rotates, sprocket wheel wherein (1) is to be fixed on the slider disc (4) by gland (2) and bolt (3), in the end face of slider disc, on the circumference that with R is radius, be shaped on 6 ball pods (20), the radius r of ball pod
1Less than the spherical radius r of ball (7), make pod on the slider disc smaller part ball of can only packing into; On the coaxial end face that is oppositely arranged fixed disk (5) of slider disc, same is that the circumference of radius is shaped on the ball pod (21) with the slider disc equal number, the radius r of this pod with r
2Spherical radius r greater than ball, its hole depth is less than ball spherical diameter 2r, greater than spherical radius r, pod hole (21) on the fixed disk, seal by baffle ring (6), and be fixed on the fixed disk (5) by the bolt (7) that is with helical spring (8), have spring base (9) on the bolt (7), fixed disk (5) connects as one by general shaft coupling and roller shaft (1), the on ﹠ off switch (22) of button alarm (23) is arranged on baffle ring (6) one sides, and be connected with its contact, when baffle ring (6) produces lateral displacement, can send out alarm equipment alarm.
