Description
Technical field
The utility model relates to mine cooling field, particularly relates to coal-face high-efficiency cooling device.
Background technology
Along with improving constantly of mining mechanization degree, mining rate constantly increases, and particularly the pit mining degree of depth constantly increases, and mine high-temperature heat evil problem is more and more serious.When mankind's mining engineering extends to deep, due to the rising of primitive rock temperature, will inevitably bring mine heat evil in various degree, mine thermal environment problem has become the key factor that restriction deep mineral resources are effectively exploited.Meanwhile, the high temperature continued will cause great harm to health and ability to work, and labor productivity is declined greatly, and accident rate increases, and constitutes major hidden danger to the life and health of operating personnel, the safety in production of mine.Underground thermal pollution becomes the another disaster after top board, gas, fire, water, the large disaster of dust five.
Mine cooling technology is the Main Means solving underground thermal pollution at present, and achieves good cooling-down effect on the whole.But, refrigeration of underground mine cooling system apparatus expensive, consume energy huge, key issue to be in cold course of conveying that cold damage is large, and loss of refrigeration capacity not only increases refrigeration duty, and getting working face cooling-down effect is reduced greatly, the localized heat evil problems such as getting working face can not get good solution always.
Existing coal-face cooling method mainly at the air intake lane arrangement air-cooling device of work plane, or arranges that in work plane small size air cooler is lowered the temperature.In work plane, step-by-step arrangement small size air cooler, work plane total length obtains uniform Temperature Distribution, and its thinking is carry out entirety cooling to work plane equally.The thinking of overall cooling is more suitable for personnel and distributes concentrated, uniform space.But coal-face is apart from long and narrow, space is large, in addition few the and skewness of faceman's quantity, and therefore overall cooling certainly will cause a large amount of wastes of cold.
Therefore, a kind of coal-face high-efficiency cooling device need be explored, from the angle reducing work plane chilling requirement, fundamentally reduce work plane refrigeration duty, to improve the cooling-down effect of coal-face.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide coal-face high-efficiency cooling device, is intended to solve the problem that the cold damage of work plane is large, cooling-down effect is undesirable.
The technical solution of the utility model is as follows: a kind of coal-face high-efficiency cooling device, comprise air intake lane air cooler, chilled water water inlet pipe, chilled water return pipe, tracking type small size air cooler, described tracking type small size air cooler and air intake lane air cooler are connected in series by chilled water water inlet pipe and chilled water return pipe.
Further, described tracking type small size air cooler has multiple, is evenly placed between coal face hydraulic support two post, and described tracking type small size air cooler comprises pyroscan, controller, electric drive axle, Motorized Operated Damper, and connects successively.
Coal-face high-efficiency cooling device of the present utility model has following beneficial effect:
1. workman's signal that tracking type small size air cooler detects according to pyroscan constantly follows the trail of workman, follows workman and rotates, make air port subtend workman always, make the hot comfort that workman reaches satisfied;
2. this device is lowered the temperature for space, workman place, discharges the invalid cooling space that area is larger, has both ensured the hot comfort of workman, and saved again large energy, realizes concentrated, the efficiency utilization of cold;
3. the air cooler providing background distinguished and admirable is arranged in this air intake lane, device busy face, makes work plane intake airflow temperature be reduced to certain value, effectively alleviates the problem that in work plane, the temperature difference is large;
4. in this device, tracking type small size air cooler is arranged between coal face hydraulic support two post, saves work plane space to greatest extent.

Detailed description of the invention
The utility model provides coal-face high-efficiency cooling device, for making the purpose of this utility model, technical scheme and effect clearly, clearly, further describes below to the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The coal-face high-efficiency cooling device of the present embodiment, comprise air intake lane air cooler (1), chilled water water inlet pipe (2), chilled water return pipe (3), tracking type small size air cooler (4), described tracking type small size air cooler (4) and air intake lane air cooler (1) are connected in series by chilled water water inlet pipe (2) and chilled water return pipe (3).
Tracking type small size air cooler (4) that the utility model is designed, tracing object is the workman (10) of mobile working, and its air port is followed workman (10) and moved and constantly rotate.Each small size air cooler controls certain space scope, and the control range of two the small size air coolers closed on is interconnected, and workman (10) often leaves a small size air cooler and enters into next small size air cooler control range simultaneously.
Described tracking type small size air cooler (4) is arranged between coal face hydraulic support (5) two post, and global design as shown in Figure 1.Its whole course of work is as follows: air intake lane air cooler (1) cools coal-face intake airflow, for work plane provides background distinguished and admirable, connected by chilled water water inlet pipe (2) and chilled water return pipe (3) between air intake lane air cooler (1) with multiple tracking type small size air cooler (4), when workman (10) arrives in tracking type small size air cooler (4) control range, pyroscan (6) senses workman's signal and signal is communicated to controller (7), controller (7) sends start signal, Motorized Operated Damper (9) is opened, tracking type small size air cooler (4) carries out cooling cooling to there being workman (10) position, now electric drive axle (8) starts, workman (10) is constantly followed the trail of according to workman's signal that pyroscan (6) detects, follow workman (10) to rotate, make air port subtend workman (10) always, when workman (10) leaves this region, pyroscan (6) senses the signal that workman (10) leaves and signal is communicated to controller (4), controller (4) sends shutdown signal, Motorized Operated Damper (9) and electric drive axle (8) are closed, now workman (10) and then moves in next tracking type small size air cooler (4) control range, and same process circulates successively.
Tracking type small size air cooler (4) eliminates the larger invalid cooling space of area, both ensure that the hot comfort of workman, and has in turn saved large energy, and reduced cooling scope, reduce refrigeration duty, achieves concentrated, the efficiency utilization of cold.
Certainly; more than illustrate and be only preferred embodiment of the present utility model; the utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the instruction of this manual; made all equivalently to substitute, obvious variant, within the essential scope all dropping on this manual, protection of the present utility model ought to be subject to.
