Description

Multi-angle air knife device for cold storage and quick-freezing tunnel Technical Field The utility model relates to the technical field of refrigeration houses, in particular to a multi-angle air knife device for a refrigeration house and a quick-freezing tunnel. Background At present, the heat insulation method of the cold storage gate in China mainly comprises the steps of constructing a buffer room and an air curtain machine for heat insulation, and the heat insulation method of the entrance and exit positions of the quick-freezing tunnel mainly comprises the step of installing a small-size PVC curtain for heat insulation. In the heat insulation method, two heat insulation doors are needed to be interlocked in a buffer room to solve the problems of large occupied area, high investment and the like, an air curtain machine is used, the problems of poor heat insulation effect, cold leakage and the like are also solved by the air knife device, and the air curtain machine has small investment and small occupied space because the equipment needs to continuously run at the inlet and outlet positions of a quick-freezing tunnel and conventional heat insulation equipment cannot be used due to the narrow space, so that the cold leakage and frosting exist in the use process of the equipment, the production efficiency of the equipment is reduced and the energy consumption is increased. The multi-angle air knife device for the refrigeration house and the quick-freezing tunnel comprises an air supply pipe and an air return pipe, a circulating pipe is connected between the air supply pipe and the air return pipe, a circulating fan is arranged on the circulating pipe, a multi-angle air supply opening is arranged on the air supply pipe, the air return pipe is provided with the air return opening, the air return opening can be well isolated through circulating air, the multi-angle air supply opening can be selected from a shutter type air supply opening or a universal nozzle, the structure is simple, the multi-angle air knife device for the refrigeration house and the quick-freezing tunnel is convenient to select, but under the condition that the humidity of external air is large, if the temperature of the circulating air is lower, the circulating fan is in contact with the external air, water drops are easy to condense, and then the phenomenon of white fog is caused. Disclosure of utility model The utility model aims to overcome the defects in the prior art and provides a multi-angle air knife device for a cold storage and a quick-freezing tunnel, which can avoid the phenomenon of white fog. The multi-angle air knife device for the cold storage and the quick-freezing tunnel comprises an air supply pipe and an air return pipe, wherein a circulating pipe is connected between the air supply pipe and the air return pipe, a circulating fan is arranged on the circulating pipe, a multi-angle air supply opening is arranged on the air supply pipe, an air return opening is arranged on the air return pipe, and the multi-angle air knife device further comprises a white fog removing device, and the white fog removing device comprises a heating component arranged on the air supply pipe or the circulating pipe or the air return pipe. Further, the heating component comprises a heating coil arranged on the return air pipe. Further, the heating assembly comprises a vertical heating pipe arranged in the return air pipe, a fixing hole matched with the vertical heating pipe is formed in the side wall of the return air pipe, and the vertical heating pipe can be inserted into the return air pipe from the return air inlet. Further, the number of the vertical heating pipes is multiple, and the vertical heating pipes are distributed at the middle position of the return air pipe.
