Embodiment

[0029] Refer to attached Figure 1 to Figure 3 As shown, a defrosting device and defrosting method for cold storage pipes provided by the present invention, specifically: include a flexible hose 1, a universal movable joint 2, a smooth pipe 4, a connecting mechanism 5, and a hammer head (using an acute angle Cone head 6, sharp-angle cone head can knock ice layer more powerfully) and rotary scraper frame 300, and rotary scraper frame 300 mainly comprises rotary scraper ring, and rotary scraper frame 300 has air jet hole 301, elastic member (this design of elastic member adopts spring 302, but not limited thereto), scraper 303. The scraper 303 is fixed on the spring 302, and the spring 302 is fixed on the body of the 300. Each scraper is connected to a spring. The spring and the scraper are evenly distributed along the concentric circle of the rotating scraper frame. The number is more than four, and the center of the concentric circle reaches each scraper. The end distances of...

Abstract

The invention provides a defrosting device and defrosting method for a coiled tube of a refrigerating cabinet. The defrosting device is characterized by comprising a flexible hose, the coiled tube anda rotary scraper frame; the flexible hose is used for connecting a compressed air source, the coiled tube comprises a smoothing coiled tube, the rotary scraper frame comprises a rotary scraper ring,an annular groove and one or more air injection holes are formed in the rotary scraper ring, the annular groove is formed in the outer peripheral end region of the rotary scraper ring, universal movable joints are installed at one ends of the air injection holes and the other ends communicated with the annular groove, the coiled tube is sleeved with the rotary scraper ring, and the rotary scraperring moves axially along the coiled tube; a cone head assembly is mounted on one side of the rotary scraper ring, and a scraper assembly is mounted on the other side of the rotary scraper ring. The defrosting device has the advantages that heating for the coiled tube is not needed in the defrosting, the defrosting of the coiled tube is carried out under the temperature of the refrigerating cabinet, the temperature of the refrigerating cabinet is not increased again, and there is no loss of refrigeration capacity of the refrigerating cabinet; by means of coordination work of breaking ice crustsand clearing away frost layers, the problem of an existing mechanical defrosting method can not remove the ice crusts is solved.

Description

technical field [0001] The invention relates to a cold storage pipe arrangement device, in particular to a defrosting device and a defrosting method for cold storage pipe arrangement. Background technique [0002] At present, most of the cooling equipment used in cold storage adopts cooling pipes, because there is air in the cold storage. When the temperature in the cold storage drops below zero degrees Celsius, the moisture in the air will condense into frost and adhere to the cooling pipes, increasing cooling. The resistance of the heat exchange between the cold in the exhaust pipe and the surrounding air will deteriorate the heat transfer effect, so it must be removed regularly. The defrosting methods for cooling pipes mainly include manual defrosting, water defrosting, electric defrosting and hot air defrosting, but the labor intensity of manual defrosting is too high. The energy consumption is very large, and hot air defrosting is the most energy-saving defrosting meth...
