Abstract

The utility model discloses a lift type heavy hammer coal removing device for a pulverized coal boiler powder pulverizing system. The lift type heavy hammer coal removing device comprises a vibration coal feeder frame, and is characterized in that two slewing ring bearings are fixedly connected onto the vibration coal feeder; a rotating shaft is arranged between the two slewing ring bearings; one end of the rotating shaft is provided with a handle; and the handle is arranged outside the two slewing ring bearings; a hand roller and a self-locking device are respectively fixedly connected onto the rotating shaft, and respectively arranged between the two slewing ring bearings; the hand roller is connected with one end of a wire cable; and the other end of the wire cable is connected with a coal removal heavy hammer. The lift type heavy hammer coal removing device is arranged on the vibration coal feeder frame at 7m place of the powder pulverizing system, so that the raw coal blockage appeared at 0m place can be handled at the 7m place. Therefore, the safety hazard that a worker handles the coal blockage at the 0m place can be avoided, labor intensity and operation time of workers can be reduced, and the device breakdown rate can be reduced too.

Description

The lift weight coal remover that is used for the pulverized-coal fired boiler pulverized coal preparation system
Technical field
The utility model belongs to the pulverized-coal fired boiler equipment technical field, especially relates to a kind of lift weight coal remover that is used for the pulverized-coal fired boiler pulverized coal preparation system.
Background technology
Coal pulverizer is with coal crusher and wears into the machinery of coal dust that it is the important auxiliary equipment of coal-powder boiler.Enter into the process of coal pulverizer ball milling cylindrical shell at the actual production raw coal, often because of ature of coal descends, water content increases with viscosity, causes coal breakage point place to pile up a large amount of raw coal, and the raw coal of accumulation forms lump easily and causes equipment to stop up, influence production.Especially for ∮ 2900 * 4700 coal pulverizers, raw coal needs by 13m place coal bunker, and the vibration feeder is fallen 0m place 45 feeder through the 7m place, flows into the ball milling cylindrical shell again.Stop up in case the raw coal lump takes place, the post personnel can only clear up chute blockage with simple tool through the crescent moon door of 0m place feeder, and not only labour intensity is big, suppresses the injury to staff's health that causes because of coal spontaneous combustion in addition simultaneously.
Summary of the invention
The purpose of the utility model provides a kind of in the coal pulverizer coal supply system, stops up in case at the 0m place raw coal takes place, and can stop up the device for coal that removes of processing at the 7m place, and the security risk of having avoided the workman to manage chute blockage everywhere at 0m reduces equipment downtime.
The purpose of the utility model realizes through following technical proposals:
A kind of lift weight coal remover that is used for the pulverized-coal fired boiler pulverized coal preparation system of the utility model; Involving vibrations feeder frame; It is characterized in that on described vibration feeder frame, being fixedly connected with two pivoting support bearings; Between described two pivoting support bearings, be provided with gyroaxis, an end of this gyroaxis is provided with handle, and this handle is located at outside described two pivoting support bearings; On described gyroaxis, be fixedly connected with hand drum and self-locking device respectively; And this hand drum and self-locking device are located at respectively between described two pivoting support bearings, and described hand drum is connected with an end of steel cable, and this steel cable other end is connected with except that the coal weight;
Described self-locking device is by the ratchet that is fixed on the said gyroaxis; The ratchet that is meshed of ratchet therewith; Be located at the pawl wrench on this ratchet, with the ratchet support that said ratchet is hinged, an end is formed with the returning spring that said ratchet is connected; Described ratchet support is fixedly connected on the described vibration feeder frame, and the other end of described returning spring is fixedly connected on the described vibration feeder frame;
The described tup that removes the coal weight is the oblate type of wide tail, and cutting edge is 30 °-45 °.
The advantage of the utility model:
Owing in the coal pulverizer coal supply system, on the vibration feeder frame at 7m place the utility model has been installed; The raw coal that the 0m place is taken place stops up; Just can stop up processing at the 7m place; The security risk of having avoided the workman to manage chute blockage everywhere at 0m reduces post labour intensity and activity duration, reduces the equipment downtime rate.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that the A of the utility model Fig. 1 is to view.
The specific embodiment
Further specify the specific embodiment of the utility model below in conjunction with accompanying drawing.
Like Fig. 1, shown in 2; A kind of lift weight coal remover that is used for the pulverized-coal fired boiler pulverized coal preparation system; Involving vibrations feeder frame 1 is characterized in that on described vibration feeder frame 1, being fixedly connected with two pivoting support bearings 11, between described two pivoting support bearings 11, is provided with gyroaxis 10; One end of this gyroaxis 10 is provided with handle 12; And this handle 12 is located at outside described two pivoting support bearings 11, on described gyroaxis 10, is fixedly connected with hand drum 9 and self-locking device respectively, and this hand drum 9 and self-locking device are located at respectively between described two pivoting support bearings 11; Described hand drum 9 is connected with an end of steel cable 7, and these steel cable 7 other ends are connected with except that coal weight 8.On the 7m place of coal pulverizer coal supply system vibration feeder frame 1, be provided with the utility model, when coal supply system normally moves, will rise to suitable height and self-locking except that coal weight 8 through hand reel 9.When 45 feeder generation raw coal in 0m place stops up, in the time of must removing, can shake and be arranged on the hand drum 9 that has self-locking device on the 7m place vibration feeder frame 1; To rise to the height of desired location except that coal weight 8 through steel cable 7; Pull pawl wrench 4, self-locking device opened, remove coal weight 8 under the effect of acceleration of gravity through having the tension weight churning of cutting edge; Chute blockage is pulverized, got into the ball milling cylindrical shell along the 45 feeder.
Described self-locking device is by the ratchet 6 that is fixed on the said gyroaxis 10; The ratchet 5 that is meshed of ratchet 6 therewith; Be located at the pawl wrench 4 on this ratchet 5,3 compositions of returning spring that ratchet support 2, one ends that are hinged with said ratchet 5 are connected with said ratchet 5; Described ratchet support 2 is fixedly connected on the described vibration feeder frame 1, and the other end of described returning spring 3 is fixedly connected on the described vibration feeder frame 1.The setting of self-locking device makes hand reel 9 be lifted at any position and can both arbitrarily stop also self-locking, when needing to discharge fast except that coal weight 8; Pawl wrench 4 is pulled open; Pawl wrench 4 and ratchet 5 are broken away from, unclamp pawl wrench 4, then pawl wrench 4 sets back under the effect of returning spring 3.
The described tup that removes the coal weight is the oblate type of wide tail, and cutting edge is 30 °-45 °.0m place 45 feeder coal breakage point is equipped with abrasionproof arc liner plate; It simultaneously also is the position that sticking easily coal forms coal piling; To be processed into except that the cutting edge of coal weight 8 with 45 arc myopia and equate; When removing coal weight 8 impact chute blockage, existing towards pounding and the chipping resultant effect being arranged, be the best approach of handling 45 feeder chute blockage.
The utility model makes in the coal pulverizer coal supply system, and the raw coal that the 0m place takes place stops up, and just can handle at the 7m place, has avoided the workman in the security risk that 0m manages chute blockage everywhere, has reduced labor strength and activity duration, has reduced the equipment downtime rate.
