Description

Technical Field

[0001] The utility model relates to the technical field of fresh air equipment, in particular to a fresh air filtering mechanism for a grain depot fan. Background Art

[0002] The function of the grain warehouse fan is to provide ventilation and cooling for grain storage. Grain will generate heat and moisture during storage. If it is not removed in time, it will cause the grain to deteriorate, mold, and even cause a fire. The grain warehouse fan circulates air to remove moisture and heat from the grain to maintain the quality and safety of the grain. At the same time, the grain warehouse fan can also keep the grain storage environment at a suitable temperature and humidity to prevent the growth of pests and mold.

[0003] There may be some common problems in the use of grain depot fan filter plate, such as filter blockage. Due to the large amount of dust, impurities and other particles in the grain depot environment, the filter plate of the filter plate may be blocked by particles after long-term use, affecting the ventilation effect of the fan. The solution can be to clean or replace the filter regularly. If the filter plate is not regularly maintained and cleaned, dust and impurities may accumulate on the filter plate, increasing resistance and affecting the ventilation effect. In the existing technology, the filter screen of the grain depot fan is mostly disassembled and cleaned manually when the fan is stopped. The main disadvantages of manually disassembling and cleaning the fan filter plate include the following aspects:

[0004] 1. High time and labor costs. Manual cleaning of the filter plate requires special personnel to operate, and it consumes time and manpower. The cleaning process may delay the progress of other work and require additional human resources. At the same time, the effect of manual cleaning of the filter plate is limited by the operator's technical level and cleaning tools, and the cleaning effect is limited. 2. Inconvenient and unhygienic. The fan filter plate is usually located at a relatively high position and requires a ladder or other auxiliary tools to be removed. Therefore, a fresh air filter mechanism for a grain depot fan is proposed to solve the above problems. Utility Model Content
