Cleaning device for inner tubes of solar vacuum tubes

Abstract

The invention relates to a cleaning device for inner tubes of solar vacuum tubes. The cleaning device comprises a cleaning tank, a partition plate is arranged in the cleaning tank and partitions the cleaning tank into a cleaning cavity and a drying cavity, a cleaning drum is transversely arranged in the middle of the cleaning cavity, two ends of the cleaning drum penetrates out of the left side wall of the cleaning cavity and the partition plate respectively, a wiping through hole is longitudinally formed in the center of a drying block which is arranged in the middle of the drying cavity, and the right side wall of the drying cavity is provided with an inner pipe outlet. At least one water nozzle is arranged at the edge of the upper opening of the cleaning tank and aligned to the cleaning drum, and the bottom of the cleaning tank is provided with at least one drainage outlet. The cleaning device for the inner tubes of the solar vacuum tubes is simple in structure and high in cleanliness, water can be saved while complete moisture of flexible cleaning strips is guaranteed by adopting the nozzles for spraying; owing to drying blocks, a drying function can be realized during cleaning.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to a solar vacuum tube inner tube cleaner. Background technique [0002] The solar vacuum tube is the core component of the solar water heater, and its production quality will directly affect the overall effect of the solar water heater. During the production process of the solar vacuum tube, the inner tube needs to be cleaned and then coated, and the cleanliness of the cleaning directly affects the coating effect. , in the prior art, clear water or ionized water is often used to rinse the inner tube of the solar vacuum tube, or wipe it with a cotton cloth soaked in water. After wiping, the inner tube needs to be dried before the coating operation can be performed. It is difficult to guarantee the degree of cleanliness and dryness of the method. Scrubbing with cotton cloth will often stick the cotton cloth to the inner pipe wall, or the water marks left during the drying...
