Circulation drying device, and fire hose drying system and method

Abstract

The invention provides a circulation drying device, and a fire hose drying system and method, and relates to the field of drying equipment. The circulation drying device comprises a pipeline used forconnecting with a drying oven, and evaporators, a condenser and a fan are arranged in the pipeline from the first end to the second end in sequence; the interior and the exterior of the pipeline are each provided with at least one evaporator, and the condenser is cooperated with a compressor, expansion valves and all the evaporators to form a heat pump system; the evaporators in and outside the pipeline are connected with the condenser through different expansion valves, and are not operated at the same time; the pipeline is cooperated with the heat pump system to form a circulating air supplystructure, and the evaporators in and outside the pipeline are arranged for obtaining heat from the outside of the pipeline during starting; and the effect of quick start to a stable circulating state is achieved, and the energy consumption is reduced.

Description

technical field [0001] The disclosure relates to the field of drying equipment, in particular to a circulating drying device, a fire hose drying system and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] The fire hose is an important equipment and tool. After the fire hose is used, there will be a lot of water and stains on the surface. If the fire hose cannot be cleaned and dried in time, the humid environment will cause the mold and rot of the hose, reducing water consumption. The pressure bearing capacity of the belt shortens the service life of the hose. [0004] The inventor found that although there are many drying equipments at present, the fire hoses after use are dried or air-dried by heating up or increasing the airflow velocity to achieve the purpose of quickly drying the fire hoses; but the current drying equipment ...

Problems solved by technology

[0003] The fire hose is an important equipment and tool. After the fire hose is used, there will be a lot of water and stains on the surface. If the fire hose cannot be cleaned and dried in time, the humid environment will cause the mold and rot of the hose, reducing water consumption. The pressure bearing capacity of the belt shortens the service life of the hose

[0004] The inventors found that although there are many drying equipments at present, the used fire hoses are dried or air-dried by heating up or increasing the air flow rate to achieve the purpose of quickly drying the fire hoses; but the current drying equipment Most of them are open structures, and the hot air flow cannot be fully utilized, resulting in waste of resources; for some circulating air drying equipment formed by heat pumps and pipelines, although circulating air is used to achieve drying, the environment inside the pipeline limits the suction of the heat pump during initial operation. The heat and heat release capacity lead to a long start-up time for the overall equipment to achieve stable cycle drying, and high energy consumption; in addition, there is currently no special cleaning and drying equipment for fire hoses, which is difficult to meet the comprehensive cleaning and drying of fire hoses processing needs
