Description
Technical field
The present invention relates to be used in a kind of cooling system, more particularly to a kind of concrete filling 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 internal heat dissipating 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 some with different curvature and the radiating tube groups that are successively distributed from bottom to top, if each layer radiating tube group by
The dry radiating blind pipe in sustained height position and lower end closed is constituted；The upper end of each radiating blind pipe be fixed on above goaf,
The lower end of each radiating blind pipe is by being fixed on the traction wire saws of above goaf and being obliquely suspended in goaf, with multichannel point
Many delivery pipes of flow tube fittings insert from corresponding radiating blind pipe upper port and extend to the lower end of the radiating blind pipe；It is many
Road diversion pipe joint is connected with water pump, blower fan respectively.
Control valve is connected between water pump and multichannel diversion pipe joint, between blower fan and the multichannel diversion pipe joint；It is each to dissipate
The lower end of hot blind 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 radiating blind pipe and realize the heat exchange with mortar, so as to quickly reduce mortar internal temperature.When scattered
Hot blind pipe because temperature is reduced produce condensation and catchment when, opening water pump can be excluded.The present invention have it is simple in construction, use
The convenient, heat of hydration excludes efficiency high, good cooling effect, low cost and other advantages.
Brief description of the drawings
Fig. 1 is the structural representation of present system installation at the construction field (site)；
Fig. 2 is the top view in Fig. 1.
In figure：Lower wall passage 1, radiating blind pipe 2, goaf 3, delivery pipe 4, upper disk passage 5, multichannel diversion pipe joint 6, water
Pump 7, blower fan 8, weight 9, pull rope 10, anchor pole 11, control valve 12.
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 radiating blind pipes 2 in sustained height position and lower end closed.Pull rope 10 is fixed by anchor pole 11
In the lower wall passage 1 positioned at the top of goaf 3；The upper disk that the upper end of each radiating blind pipe 2 is held within the top of goaf 3 leads to
In road 5, respectively the lower end of radiating blind pipe 2 is drawn by pull rope 10 and is obliquely suspended in goaf 3.With multichannel diversion pipe joint
Many delivery pipes 4 of 6 connections insert from the corresponding radiating upper port of blind pipe 2 and extend to the lower end of the radiating blind pipe, multichannel point
Flow tube joint 6 is connected with water pump 7, blower fan 8 respectively.
In order to easy to use, between water pump 7 and multichannel diversion pipe joint 6, between blower fan 8 and the multichannel diversion pipe joint
It is connected to control valve 12.
In filling casting process, in order to avoid radiating blind pipe 2 is floated by mortar and cause the minimum point of the radiating blind pipe
Position changes, and is hung with and is made up of fragment of brick or other construction wastes by tying up or packing in the lower end of each radiating blind pipe 2
Weight 9.
Operation principle：When carrying out filling construction to mine large scale goaf using concrete, first by concrete casting
Bottom in goaf 3；When reaching certain depth, respectively with pull rope 10 by anchor pole 11 by many radiating blind pipe 2 two
End is accordingly fixed in lower wall passage 1, upper disk passage 5, it is ensured that the lower end of radiating blind pipe 2 tilts sagging and forms hyperbolic naturally
Linear structure；Then each radiating blind pipe 2 is covered with mortar again.When concrete covers up to certain thickness, then by above-mentioned side
Many other radiating blind pipes 2 are fixed in goaf 3 by method；So operate repeatedly, until goaf 3 is filled up.Then open
Open blower fan 8 and the hot-air in blind pipe 2 that each layer is radiated by delivery pipe 4 is excluded, you can realize in each section mortar in goaf
Portion cools；When radiate blind pipe 2 because cooling reduction is produced condensation is catchmented cause that radiating can not be vented when, switching control valve 12, open
The condensed water in corresponding radiating blind pipe 2 can be excluded by delivery pipe 4 by opening water pump 7.So operate repeatedly, you can fast prompt drop
Temperature inside low goaf filling body, so that the rapid consolidation and sclerosis of obturation.
