The device to collapse.
Background technology
In recent years, many collieries of Yulin, Shanxi and Inner Mongol carry out large scale mining, surrounding environment are caused sternly
The destruction of weight, mining subsidence cause that the main soil in mining area caves in, road caves in, Building Deformation etc..It is existing solution subsidence or
The effective ways to cave in are underground filling method and overlying strata separation layer carrying space filling method, more using coal ore and sandy soil as filling material
Material, while, it is necessary to filled and be compacted with loading machine.To so need to be gathered with loading machine, convey more sandy soil, can cause compared with
Big input.Moreover, such burying method, which can only administer surface, the region collapsed occurs, can not then locate for the cavity of inside
Reason.If things go on like this, it will form potential safety hazard, be unfavorable for the safety in production life in mining area.
The content of the invention
The device that earth's surface caves in, the apparatus structure are filled up using flue gas and quick lime it is an object of the invention to provide a kind of
It is reasonable in design, it is simple and easy, it can effectively solve the problem that sandy soil in the prior art and gangue landfill method can not go deep into sky inside earth's surface
The problem of gap.
The present invention is to be achieved through the following technical solutions：
The device that earth's surface caves in is filled up using flue gas and quick lime the invention discloses a kind of, including air admission unit and enters slurry
Unit；The air admission unit, including fume pipe and blower fan, fume pipe can extend into hole to be filled up；It is described to enter to starch unit,
The container starched including mud tube and for taking up quick lime, mud tube can extend into hole to be filled up；Fume pipe and mud
The direction that pipe stretches into hole to be filled up is different；The exhaust being connected with earth's surface external environment is also set up on hole to be filled up
Pipe, is additionally provided with overflow pipe on blast pipe.
The first stop valve, thermometer and first flowmeter are provided with the pipeline of fume pipe.
Pump and the second stop valve are provided with the pipeline of mud tube.
Second flowmeter is provided with blast pipe.
Agitator is additionally provided with container.
Fume pipe exports with chimney of electric plant or kiln outlet is connected.
Compared with prior art, the present invention has technique effect beneficial below：
It is disclosed by the invention to fill up the device that earth's surface caves in using flue gas and quick lime, including air admission unit and to enter slurry single
Member, air admission unit include fume pipe and blower fan, and flue gas is pumped to by blower fan in the hole under earth's surface.Entering to starch unit includes mud
The container of quick lime slurry is managed and takes up, quick lime slurry can be also sent into the hole under earth's surface by mud tube, when being passed through in hole
Flue gas and quick lime slurry contact when, because the two is respectively provided with mobility, hole can be loaded, and the two can also send out
Biochemical reaction, so as to complete the landfill to hole under earth's surface.The device is ingenious in design, easy to use, energy-conserving and environment-protective, Neng Gouyou
Effect solves the problems, such as that existing sandy soil and gangue landfill method can not go deep into earth's surface internal voids.
Further, flowmeter is respectively provided with fume pipe and blast pipe, quick lime slurry and flue gas can be monitored
Carry out state is reacted, when the difference in flow of two flowmeters is close to zero, shows that reaction terminates.
Further, agitator is also set up in the container for taking up quick lime slurry, quick lime can be starched and be sufficiently stirred
It is even.
Further, fume pipe can be connected with from chimney of electric plant outlet or kiln outlet, can make full use of the energy,
Energy-conserving and environment-protective.

Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings：
Referring to Fig. 1, in the lower section of earth's surface 6, there is soil horizon 9 and hole 8.It is disclosed by the invention to utilize flue gas and raw stone
Ash fills up the device that earth's surface is caved in, including air admission unit and enters to starch unit；The air admission unit, including by fume pipe 2 and blower fan
1, fume pipe 2 can extend into hole 8 to be filled up；It is described to enter to starch unit, including mud tube 10 and for take up quick lime slurry
Container 14, mud tube 10 can extend into hole 8 to be filled up；Also set up on hole 8 to be filled up and earth's surface external environment
The blast pipe 7 being connected.
The first stop valve 3, thermometer 4 and first flowmeter 5 are provided with the pipeline of fume pipe 2.In the pipe of mud tube 10
Road is provided with the stop valve 11 of pump 12 and second.Overflow pipe 16 and second flowmeter 17 are provided with blast pipe 7.
