Put.
Background technology
Horizontal boiler waste heat section includes water cooling section region, superheat section region, convection section region, economizer region, air preheater
Region.Each area segments set dust inlet, collect Ash water to feed bin using embedded scraper transporter, then utilize pneumatic transporting
Grey pipeline delivers to transhipment ash silo.
Embedded scraper transporter be it is a kind of in the housing of the rectangular cross section of closing, it is continuous by means of moving flight chain
The transporting equipment of delivery of bulk material, it has said device features rational structure, operates steadily, and noise is low, embedded scraper transporter be by
The material conveying system equipment that metallurgy, mine, thermal power plant welcome.
Embedded scraper transporter is mainly by the trough of closed section, flight chain, the parts group such as drive device and tensioning apparatus
Into, device structure is simple, small volume, good seal performance, installation and maintenance are more convenient；Craft lectotype and arrangement are more flexible；
When conveying flying upward property, poisonous, high temperature, inflammable and explosive material, it can improve working conditions, reduce environmental pollution.
As the conveying equipment of conveying each waste heat section lime-ash of horizontal boiler, it has the characteristics of fed distance is long, adds
During design embedded scraper transporter for interval start conveying, interval time it is longer, and temperature of charge highest can more than 450 DEG C, although
The housing of water cooling section and superheat section closed section has cooling device, but cold and hot runs the length of chain when alternately changing
Change is very big, and common tension device can not compensate, and the driving wheel and driven pulley for causing chain and embedded scraper transporter go out
Now loosen or tension phenomenon, cause the stuck phenomenon of carrier chain chain, gently then chaser influence conveying, it is heavy then cause equipment destructiveness
Damage.
The content of the invention
The utility model provides a kind of embedded scraper transporter thermal compensation device, and the purpose is to solve embedded scraper transporter
Chain is because of the alternate run in hot and cold environment, and the length of chain changes greatly, so as to cause chain and bury scraper plate
The driving wheel and driven pulley of conveyer occur loosening or the problem of tension states.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is as follows：
A kind of embedded scraper transporter thermal compensation device, including thermal compensation device body and casing, the thermal compensation device sheet
2 slidable adjusting rods are interspersed with body, are each arranged with the first spring and bearing block on 2 adjusting rods, described
One end of one spring is withstood on thermal compensation device body, and the other end of first spring is consolidated by adjusting nut and fastening screw nut
It is scheduled on adjusting rod, the first spring original state is compressive state；The bearing block is fixed on adjusting rod, the bearing
The driven pulley of embedded scraper transporter is provided between seat.
Further, the casing is provided with slide rail, and the bottom surface of the bearing block is arranged on slide rail.
Further, in addition to balancing pole and second spring, the balancing pole are fixed between 2 adjusting rods, institute
The one end and balancing pole for stating second spring are fixed, and the other end is fixed with casing, and the original state of the second spring is compression shape
State.
From above-mentioned to description of the present utility model, compared to the prior art, the utility model has the advantage of：
1. when chain expanded by heating, because the original state of the first spring is in compressive state, so passing through first
The elastic force of spring promotes adjusting rod to be moved on thermal compensation device body, and then ensures the master of chain and embedded scraper transporter
Driving wheel and driven pulley cannot be loosened after；When chain is by cold events, fastening screw nut and adjusting nut are first adjusted, is made
First spring and adjusting rod are relaxed state, then move the position of adjusting rod, finally adjust fastening screw nut and adjusting nut again, make
First spring in compressive state and being fixed on adjusting rod, so as to ensure the driving wheel of chain and embedded scraper transporter and from
Driving wheel is not in tension phenomenon；The elastic force for such as crossing the first spring is insufficient to allow adjusting rod to move, can by adjusting nut come
Adjust the decrement of the first spring.
2. casing is provided with slide rail, the bottom surface of bearing block is arranged on slide rail, is using the advantages of program：One
Make the movement of bearing block more smooth, secondly playing a part of supporting bearing base, and then reduce adjusting rod in movement with vulcanizing
Repay caused frictional force between device body.
3. the setting of balancing pole and second spring can make 2 adjusting rod synchronizing movings, avoid the occurrence of an adjusting rod and move
Dynamic distance is big, and the situation that the distance of another adjusting rod movement is small；The original state of second spring is compressive state, when defeated
When sending chain expanded by heating, thrust can be provided to adjusting rod, be further ensured that adjusting rod can be on thermal compensation device body
It is mobile.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Structural representation when Fig. 2 is the utility model inorganic shell.
Embodiment
With reference to the accompanying drawings 1 and accompanying drawing 2 illustrate specific embodiment of the present utility model.
A kind of embedded scraper transporter thermal compensation device, including thermal compensation device body 1 and casing 2, thermal compensation device body 1
On be interspersed with 2 slidable 3,2 adjusting rods 3 of adjusting rod and be each arranged with the first spring 4 and bearing block 5, the first spring 4
One end withstand on thermal compensation device body 1, the other end of the first spring 4 is fixed on tune by adjusting nut 6 and fastening screw nut 7
