1. the device that the heater for improving down-hole ambient temperature is a kind of change down-hole ambient temperature of designed, designed processing.It should Device is mainly made of cabinet, heating tube, aqueous slkali, changes thermal energy by electric energy dress.Cabinet uses 40 × 40mm hollow square steel Welding growth 3m, width 2.5m, high 2m frame, frame surrounding are blocked tightly using colored steel, form cabinet.One side opening of cabinet is used for Booster air inlet is connected, other side lower openings are as air inlet.Working environment at coal mines temperature is improved for winter, is improved The operating environment of worker shortens the time that worker overhauls pneumatic tools, improves working efficiency.

Technical field

The invention patent is a kind of device that underground coal mine improves environment temperature, which overcomes previous heater Disadvantage.Traditional heater generallys use by installing hot-blast stove near well head and burns coal formula hot-blast stove, cause one to environment The utilization efficiency of fixed destruction, heat transmitting is lower, and to close to well head.Material and at high cost, and warm wind effect is poor. And be used for a long time and be easy to cause security risk, it influences to keep the safety in production.Subsurface environment can be greatly improved in the use of the heater Temperature improves operating environment, improves production efficiency.

Background technique

The Northwest's teletostage temperature is lower, especially influences on a phase slope construction.One phase slope construction working face in the pit is logical Wind mode is local ventilation, i.e., installation booster in ground passes through air duct to air supply of working face.Teletostage underground coal mine temperature compared with It is low, environment on coalface sharp temperature drop is caused bringing ground cold air into underground by air duct, to production equipment and personnel Extreme influence is caused, therefore it is very necessary for carrying out heating to working face.

Previous well head heat preservation mainly takes well head to close measure, while hot-blast stove or warm is installed within the scope of closing derrick Gas.This kind of method needs partially enclosed well head range, and because slope mouth range is bigger, closed material cost is very high.And Wellhead temperature promotion effect is unobvious, and downhole temperature is more difficult to reach ideal effect.Well head setting heater there is also Some potential safety problems, therefore this kind of warm wind method has been rarely employed in recent years.

In view of the above problems, being badly in need of designing the warm wind that a kind of safety is good, economic input is smaller, using effect is relatively good Device.Subsurface environment effect can be improved using heater cooperation booster, when use can by adjusting heating tube quantity, Reach temperature control effect.

The content of invention

Colored steel, is fixed on frame by the frame that growth 3m, width 2.5m, high 2m are welded using square steel using electric hand drill, will Cabinet is closed good.One side opening of cabinet is for connecting booster air inlet, and other side lower openings are as air inlet.In cabinet Fixed several heating tubes heat air.Warm wind is sucked when local ventilation machine operation, warm wind is sent to working face in the pit.

Detailed description of the invention

Fig. 1 as shown in Figure 1 improves the heater structure chart of down-hole ambient temperature

1, square steel 2, colored steel 3, heating tube 4, booster 5, air inlet 6, fan supporter in figure

For the device using self-control array heating tube, tubing is 10mm steel pipe.Built-in aqueous slkali is wide using work for heating 380V power supply is as heating source, so that electric energy is converted into thermal energy, maximum operating temperature reaches 500-550 DEG C.It is controlled by control switch The start-stop of heating tube, when use, open electrothermal tube, pass through working face temperature variations and adjust electrothermal tube and open quantity.To prevent Negative pressure is excessive in heating air box, opens wide 5 () () mm in downside, length 600mm air inlet, and air inlet size can be adjusted suitably.

The utility model has the advantages that the device is used in certain coal mine gun diging face, the working environment of underground is improved, underground is improved Working face temperature, reduces the maintenance pneumatic tools time, and working efficiency is greatly improved.Each heating tube power is 3KW, heater are that 12 groups of heating tube power consumptions are 36 degree/hour, and the daily electricity charge are 600 yuan/day.Maintenance personnel shortens maintenance The time of pneumatic tools a quarter improves normal cyclic rate, removes cost and processing maintenance cost, work face ring can be improved Operating efficiency is improved in border.Effect comparison is shown in Table 1 before and after heater use.

Table 1

Advantage:

1) device is voluntarily processed, raw material sources are convenient, cost is relatively low.

2) device is easily installed and safeguards, can be recycled.

3) for the device with electrothermal tube and blower, temperature rise effect is good.

4) device is stable, reliable, no security risk.

Specific embodiment

In certain mine main slant construction period, booster, the simultaneous processing heater and wind are installed at well head 20m Machine connects, and fixes a certain number of heating tubes in heater.Heating tube is opened during fan operation, blower generates heating tube Warm wind be aspirated through air duct and be sent to working face, improve environment on coalface temperature.

For the heater in certain coal mine main incline shaft gun diging face application process, temperature rise effect is obvious, operating aspect, at This is low, safety coefficient is high, practical, has good promotional value.
