Abstract
The utility model discloses an antifreezing protective industry and mining hot wind heating device which comprises a draught fan (1), a shell body (2), an air heater (3), a hot air outlet (4), a heating medium feeding pipeline (5) and a refrigerant discharging pipeline (6). An electrically operated valve (7) is connected to the refrigerant discharging pipeline (6). Due to the fact that the electrically operated valve is additionally installed on the refrigerant discharging pipeline, refrigerant can be discharged successfully under the accidental situation due to electric control design matched with the electrically operated valve, the refrigerant is prevented from being frozen in the air heater, and the air heater is protected.
Description
Technical field
The utility model belongs to industrial and mineral hot air heating apparatus technical field, particularly be a kind of anti-frost protection type industrial and mineral hot air heating apparatus.
Background technology
At present, each industrial and mining enterprises at home, northern coal mining enterprise particularly, for preventing that winter, well head froze or bob ice, various hot air heating apparatus are set usually, by the heat exchange heating to cold wind, carry warm braw to well head, guarantee that well head environment border temperature remains at more than 2 ℃, prevent that icing or bob ice etc. from hindering the generation of industrial accident.
Often there is following problem in the hot air heating apparatus that adopts in running at present: because hot air heating apparatus mainly is the heats cold air, the heating agent that adds hot air is two kinds of steam or high temperature water, through heat medium temperature meeting step-down after the heat exchange, become condensed water behind the steam heat-exchanging, become water at low temperature after the high temperature water heat exchange, under the normal condition, condensed water or water at low temperature can be along with pipeline discharges or recycling, but if meet emergency case, heating agent can not flow in heater, and the heating agent of retaining within it just can not normally be discharged, along with the reduction of temperature, can in heater, freeze, heater is caused damage.
Summary of the invention
In order to solve above technical deficiency, the purpose of this utility model is to propose a kind of anti-frost protection type industrial and mineral hot air heating apparatus.Can under the unexpected situation refrigerant in the air heater in time be discharged occurring, prevent freezingly, play the effect of protection heater.
The utility model realizes that the technical measures that above-mentioned purpose is taked are: a kind of anti-frost protection type industrial and mineral hot air heating apparatus is on the existing main architecture basics that is entered the hot air heating apparatus that pipeline and refrigerant discharge line form by housing, blower fan, air heater, hot-blast outlet, heating agent, installs electrically operated valve additional at the refrigerant discharge line.
Electrically operated valve described in the utility model by screwed connection on the refrigerant discharge line.
The utility model is by installing an electrically operated valve additional at the refrigerant discharge line; by supporting with it automatically controlled design, can under the unexpected situation of appearance, refrigerant be discharged smoothly; prevent that refrigerant from freezing, and plays a protective role to air heater thereby reach in air heater.
Description of drawings
Fig. 1 is the hot air heating apparatus structural representation.
Fig. 2 is the utility model schematic diagram.
Among the figure: 1, blower fan, 2, housing, 3, air heater, 4, hot-blast outlet, 5, heating agent enters pipeline, 6, the refrigerant discharge line, 7, electrically operated valve.
The specific embodiment
By reference to the accompanying drawings, it is as follows to provide embodiment of the present utility model.
As Fig. 1 in conjunction with shown in Figure 2: the described anti-frost protection type of present embodiment industrial and mineral hot air heating apparatus comprises that blower fan 1, housing 2, air heater 3, hot-blast outlet 4, heating agent enter pipeline 5, and refrigerant discharge line 6; blower fan 1 is positioned at the entrance point of housing 2; air heater 3 is arranged on housing 2; hot-blast outlet 4 is positioned at the port of export of housing 2; heating agent enters pipeline 5 and is connected with the import and export end of air heater 3 respectively with refrigerant discharge line 6, is connected with electrically operated valve 7 by the screw thread mode on refrigerant discharge line 6.What electrically operated valve 7 adopted is known products, normally coupled together by electric operator and valve, it can be divided into two parts up and down, the first half is YE, the latter half is valve, be to utilize electric energy to connect electric operator as power to drive valve, realize switch, the adjusting action of valve.Thereby play switch or adjusting purpose to pipeline medium.
During use, outdoor heating agent (steam or high temperature water) enters pipeline 5 by heating agent and enters air heater 3, outdoor cold wind enters housing 2 by blower fan 1, with the heating agent generation interchange of heat of flowing in the air heater 3, heated air enters the well head air channel by hot-blast outlet 4, and the refrigerant after heat exchange is discharged by refrigerant discharge line 6.Under the normal condition, the electrically operated valve 7 that is arranged on the refrigerant discharge line 6 is in closed condition, design temperature in its control system, as, (temperature 〉=0 of general refrigerant ℃ goes wrong when being down to 0 ℃ of proof system to be designed to 0 ℃.And this temperature can be regulated according to site specific).When emergency case occurring, namely when the temperature in the air heater 3 was down to the temperature (0 ℃) of control system setting, electrically operated valve can be opened automatically, the heater inner cold water is forced to discharge, prevent that refrigerant from freezing in heater, heater is freezing, and influence is used.
Claims (2)
1. anti-frost protection type industrial and mineral hot air heating apparatus; comprise that blower fan (1), housing (2), air heater (3), hot-blast outlet (4), heating agent enter pipeline (5) and refrigerant discharge line (6), is characterized in that: be connected with electrically operated valve (7) at described refrigerant discharge line (6).
2. anti-frost protection type industrial and mineral hot air heating apparatus according to claim 1, it is characterized in that: described electrically operated valve (7) is connected on the refrigerant discharge line (6) by the screw thread mode.
