Description

Technical Field

[0001] This utility model relates to the field of tobacco processing equipment, specifically to a wastewater recycling treatment device suitable for tobacco leaf processing, particularly suitable for cleaning the water storage device of the dust removal and odor treatment system during the tobacco leaf processing production process. Background Technology

[0002] In the tobacco processing industry, many steps generate moisture and dust, such as loosening and rehydration, thin-plate drying, and airflow drying. These processes produce water vapor, tobacco dust, and tobacco odor. Therefore, pneumatic conveying systems are installed to send the exhaust gases into dust removal and odor treatment systems. The odor treatment system typically includes a spray system, whose main function is to wash away small particles and water-soluble molecules from the exhaust gases. The treated water then enters a water storage system, where it undergoes basic treatment before being used in the spray system for dust suppression. This method conserves a significant amount of water resources.

[0003] However, even after basic treatment, the purified water, continuously flowing into the storage tank for extended periods, still retains sediment, grease, and other impurities, affecting the operation of the spray system. Furthermore, the storage tank's large capacity and limited inlet size make it inconvenient for cleaning devices like brushes to access it. Manual cleaning would result in low efficiency. Using a self-cleaning circulating storage tank is expensive. Additionally, the self-cleaning circulating storage tank keeps the cleaning devices immersed in a liquid environment for extended periods, making them prone to oil and other contaminants that are difficult to remove and can easily cause corrosion and damage to the cleaning devices.

The circulating water storage bucket comprises a cleaning assembly detachably connected with the circulating water storage bucket 110, and the cleaning assembly comprises a purification bucket cover 120, a rotating motor 130, a rotating main shaft 140, an assembly tray 150, a rotating rod 160 and a cleaning fan blade 170.

[0056] The controller controls the rotation motor 130 and the steam generating device 181 to start and open the cleaning work.

[0057] The cleaning mode is automatically selected according to the dirt type:

[0058] When the powder deposition is more (cleaned once every quarter): the medium-speed rotation cleaning in the bristle layer is started, when the tobacco tar deposition is more (cleaned once every year): the steam nozzle is activated to cooperate with the brushing, and after the cleaning is completed, the sewage is discharged from the sewage outlet.
