Description

Technical Field

[0001] The present invention relates to the field of grain depots, and particularly to a wall purification system and prevention and control method for grain depots or food warehouses. Background Art

[0002] After the grain is taken out of the warehouse, we must properly treat the walls of the grain depot. Otherwise, dust and insects may be left behind, which will bring unnecessary trouble to the subsequent grain storage work.

[0003] The cleaning work of the grain depot walls is a very important link to ensure the safety of grain storage and maintain environmental hygiene. The following lists several common methods for cleaning the grain depot walls. You can choose the most suitable cleaning plan according to the actual situation: Applicable scenarios: Suitable for daily maintenance or when the dust accumulation on the wall is relatively light. Specific method: A soft brush or a vacuum cleaner can be used to remove the dust and debris on the wall. During the operation, it should be noted that hard tools should be avoided to prevent damage to the wall.

[0004] Applicable scenarios: When it is necessary to prevent pest infestation or bacterial growth. Specific measures: After disinfection treatment, thorough ventilation is required to ensure that the quality of the grain will not be affected.

[0005] To extend the service life of the grain depot walls and reduce the cleaning difficulty, it is recommended to regularly check the wall conditions, promptly clean the stains, and apply anti-mildew and waterproof coatings. The purpose of doing this is to ensure the long-term stability and cleanliness of the walls.

[0006] This cleaning measure is particularly applicable to the scenarios after the grains such as wheat and corn that are prone to generating dust are taken out of the warehouse.

[0007] When performing the cleaning operation of the grain depot walls, the following specifications should be followed: ① The cleaning path should follow the three-dimensional cleaning sequence of "top → bottom → corners"; ② The dust residue per square meter must be less than 0.3 grams, meeting the national standard GB / T29890-2023; ③ Special attention should be paid to the pollution zone within 30 centimeters around the ventilation openings and key treatment should be carried out.

[0008] Currently, the cleaning of the walls of grain depots is all done manually, which requires climbing heights and is prone to missing some areas. The cleaning is labor-intensive and material-consuming, and the effect is not good.

[0009] Moreover, if fixed machinery is set up, it is easy to affect the later warehouse capacity. Because the grain is mobile, it is necessary to avoid the parts in the corners of the wall as much as possible. It is best to set it above the grain surface.
