Freezing-preventing heat pump type hot air heating device

Abstract

The invention discloses a freezing-preventing heat pump type hot air heating device which comprises a hot air heating device, an air dryer (5) and a heat pump (6), wherein the hot air heating device comprises an air blower (1), a shell (2), a fin tube (3) and a hot air outlet (4); the inlet and the outlet of the heat pump (6) are correspondingly connected with the inlet and the outlet of the fin tube (3), and the air dryer is connected with a hot air outlet. The heat pump is used for mining energy stored in an environment medium, the temperature is increased through a heat transfer working medium circulating system for utilization, and the power consumed by the whole heat pump device is only one part of output power, thus a large quantity high-grade energy can be saved, waste emission is reduced, and the environment is protected. A moving mechanism arranged in the freezing-preventing heat pump type hot air heating device can be used for conveniently and rapidly conveying the freezing-preventing heat pump type hot air heating device to a place needing the freezing-preventing heat pump type hot air heating device. The freezing-preventing heat pump type hot air heating device is not limited by a heat source pipeline and a site condition, and can provide hot air at any time and place.

Description

technical field [0001] The invention belongs to the technical field of hot air heating devices, and mainly relates to an anti-freezing heat pump type hot air heating device. It is widely used in mine wellhead anti-freezing, emergency rescue and disaster relief, such as eliminating ice on roads, transmission towers, transmission lines, etc., sending warm air in underground emergencies, heating without heating facilities, etc. Background technique [0002] At present, in mine production, in order to prevent the shaft from freezing in winter, it is necessary to supply warm air to the underground to ensure that the ambient temperature at the wellhead is always kept above 2°C to prevent accidents such as freezing or falling ice that hinder safe production. Due to some wellheads being far away from the heat source or limited by other factors, heat source pipelines cannot be provided, and traditional hot air blowers cannot be installed, resulting in inability to produce in winter; ...

AI Technical Summary

Problems solved by technology

Due to some wellheads being far away from the heat source or limited by other factors, heat source pipelines cannot be provided, and traditional hot air blowers cannot be installed, resulting in inability to produce in winter; although some wellheads are equipped with hot air blowers, when there is a problem with the heat source-boiler or pipe network system, It is impossible to send warm air to the underground, so the production can only be stopped; or when there is a sudden underground accident and it is necessary to send warm air to a certain place, the installation time of the traditional hot air system is too long to meet the time requirements;

[0003] In addition, in the severe winter season, transmission towers, transmission lines and other equipment are often frozen due to failure to clear them in time, resulting in accidents such as transmission towers toppling, transmission lines breaking, etc.

Restricted by the laying of heat source pipelines, there are problems such as heating difficulties in some places that require heating
