Description
Technical field
The present invention relates to be used in a kind of cooling system, more particularly to a kind of Concrete Filled mine worked-out section work progress
The heat of hydration, the cooling system of the large-scale obturation internal temperature of reduction are discharged, belongs to the heat of hydration in concrete filling construction operation and dissipates
Thermal.
Background technology
During consolidated fill is carried out to mine large scale goaf using concrete, because obturation volume is big, water
Divide content and temperature height, filling space occlusion, the environment of this wet vexed high temperature is unfavorable for cement aquation；Cementing is acted on
Weakened or delayed, cause strength of filling mass to reduce, or even be still granular media or mud lake shape for a long time.Not only cause cement a large amount of
Waste, add filling expense, and exploitation safety cannot be ensured., must in order to which the normal condensation for accelerating filling slurry is hardened
The heat produced in cement hydration process must in time be discharged in time, so as to improve cement utilization rate, promote strength of filling mass fast
Speed increases.
The heat of hydration generally is reduced by the way of addition low hydration heat cementing agent at present, which method is although convenient, but
Higher is required to binder materials, and cost is also high, pre-stage test amount is big.Such as the change of tailings property, its bonding capacity also can be complete
It is complete to change, strength of filling mass can be had a negative impact, there is potential safety hazard.In addition, low hydration heat binder materials specific aim compared with
By force, without general applicability；Tailings of different nature is both needed to carry out a large amount of lengthy and tedious experiments.Therefore a kind of peace of development is needed badly
Entirely, conveniently, efficiently, low cost, the good heat of hydration heat abstractor of heat elimination and cooling effect.
The content of the invention
For drawbacks described above present in prior art, the present invention is intended to provide a kind of simple in construction, easy for installation, radiating
The mine Large god area obturation heat of hydration cooling system of good cooling effect.
To achieve these goals, the present invention uses following technical scheme：It includes blower fan and radiating subassembly；The radiating
Component is made up of the multi-layer heat dissipation pipe group successively arranged from bottom to top, and each layer radiating tube group is by some in sustained height position
The U-shaped radiating tube put is constituted；The two ends of each U-shaped radiating tube are fixed on the bending section of above goaf, each U-shaped radiating tube by respectively
It is fixed on the traction wire saws of above goaf and is obliquely suspended in goaf, each U-shaped radiating pipe port is inserted respectively simultaneously
Many drainpipes for extending to the U-shaped radiating tube bending section are connected by multichannel distributive pipe joint with water pump, insert each U-shaped respectively
The blast pipe of another port of radiating tube is connected by multichannel gas-distributing pipe joint with blower fan.
Control valve is connected between water pump and multichannel distributive pipe joint, between blower fan and multichannel gas-distributing pipe joint；It is each U-shaped scattered
The bending section of heat pipe is hung with weight.
Compared with the prior art, the present invention is by adopting the above-described technical solution, therefore using air blower or air-introduced machine
Promote the air flow in each U-shaped radiating tube and realize the heat exchange with mortar, so as to quickly reduce mortar internal temperature.Work as U
Type radiating tube because temperature is reduced produce condensation and catchment when, opening water pump can be excluded.The present invention have it is simple in construction, make
Efficiency high, good cooling effect, low cost and other advantages are excluded with the convenient, heat of hydration.
Brief description of the drawings
Fig. 1 is the structural representation of present invention installation at the construction field (site)；
Fig. 2 is the top view in Fig. 1.
In figure：Lower wall passage 1, U-shaped radiating tube 2, goaf 3, drainpipe 4, upper disk passage 5, multichannel gas-distributing pipe joint 6,
Water pump 7, blower fan 8, weight 9, pull rope 10, anchor pole 11, multichannel distributive pipe joint 12, control valve 13, blast pipe 14.
Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in Fig. 1~2：Radiating subassembly is made up of some radiating tube groups being successively distributed from bottom to top, and each layer dissipates
Heat pipe heat is made up of some U-shaped radiating tubes 2 in sustained height position.Pull rope 10 is held within by anchor pole 11 respectively
In the lower wall passage 1 and upper disk passage 5 of the top of goaf 3；The two-port of each U-shaped radiating tube 2 is by leading in upper disk passage 5
Messenger 10 is fixed, and the bending section of each U-shaped radiating tube 2 is drawn by the pull rope 10 in lower wall passage 1 and is obliquely suspended to
In goaf 3.Each port of U-shaped radiating tube 2 is inserted respectively and extends to many (drainings of drainpipe 4 of the U-shaped radiating tube bending section
The external diameter of pipe is less than the internal diameter of U-shaped radiating tube) connected by multichannel distributive pipe joint 12 with water pump 7, each U-shaped radiating is inserted respectively
The blast pipe 14 of another port of pipe 2 is connected by multichannel gas-distributing pipe joint 6 with blower fan 8.
In order to easy to use, between water pump 7 and multichannel distributive pipe joint 12, between blower fan 8 and multichannel gas-distributing pipe joint 6
It is connected to control valve 13.
In filling casting process, in order to avoid U-shaped radiating tube 2 is floated by mortar and cause the minimum of the U-shaped radiating tube
Point position changes, and is hung with the bending section of each U-shaped radiating tube 2 by fragment of brick or other construction wastes by tying up or packing
The weight 9 being made.
Operation principle：Using concrete to mine Large god area carry out filling construction when, first by concrete casting in
The bottom in goaf 3；When reaching certain depth, respectively with pull rope 10 by anchor pole 11 by the two ends of many single u-shaped radiating tubes 2
Ground is fixed in disk passage 5, the bending section of each U-shaped radiating tube 2 is drawn by the pull rope 10 for being separately fixed at the top of goaf 3
And be obliquely suspended in goaf 3,
Ensure that the bending section of U-shaped radiating tube 2 tilts sagging and forms hyperbolic configuration naturally (referring to Fig. 1)；Then again
Each U-shaped radiating tube 2 is covered with mortar.When concrete covers up to certain thickness, then as stated above by many other U
Type radiating tube 2 is suspended in goaf 3；So operate repeatedly, until goaf 3 is filled up.It is then turned on blower fan 8 and leads to
Cross blast pipe 14 to exclude the hot-air in each U-shaped radiating tube 2, you can realize each section mortar internal cooling in goaf；When U-shaped
When radiating tube 2 because being catchmented cooling reduction generation condensation causes that radiating can not be vented, switching control valve 13, unlatching water pump 7
The condensed water in corresponding radiating blind pipe 2 is excluded by drainpipe 4.So operate repeatedly, you can quick reduction goaf is filled
The temperature in internal portion is filled out, so that the rapid consolidation and sclerosis of obturation.
