Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment, in particular to cooling equipment for an air compressor used in liquid oxygen production. Background Art

[0002] Liquid nitrogen refers to the liquid obtained by melting inert, colorless, odorless, non-corrosive, and non-flammable nitrogen gas at extremely low temperatures. Liquid nitrogen is an inert, colorless, odorless, low-viscosity, non-corrosive, non-flammable, transparent liquid at extremely low temperatures. When it vaporizes, it absorbs a large amount of heat and causes frostbite on contact. If the human body comes into contact with liquid nitrogen without protective measures, the skin may suffer severe frostbite. If the nitrogen gas produced by vaporization at normal pressure is excessive, it may cause the oxygen partial pressure in the air to drop, causing hypoxia and suffocation.

[0003] After searching, Chinese patent announcement number: CN209655864U discloses an air compressor aftercooler for liquid oxygen and liquid nitrogen production, which can prevent scale from affecting the air cooling effect; it includes a cooling chamber, two groups of cooling pipes, a fixed plate and a partition plate, a cooling cavity is provided in the cooling chamber, the top and bottom of the fixed plate are respectively fixed to the right top and right bottom of the cooling chamber, the upper and lower parts of the fixed plate are respectively provided with four groups of fixed ports, the left and right ends of the partition plate are respectively connected to the right middle part of the fixed plate and the right middle part of the cooling chamber, one end of the two groups of cooling pipes are respectively connected to the two groups of fixed ports located above, the left sides of the two groups of cooling pipes respectively bypass the left top and left bottom of the cooling chamber, the other ends of the two cooling pipes are respectively connected to the two groups of fixed ports located below, and the top right side of the cooling chamber is connected with an air inlet; it also includes a clean water tank, a filter screen, an absorption box and two groups of reverse osmosis membranes.

[0037] Working principle: When in use, first inject the hot fluid into the tank body 1, then inject the cooling water into the filter box 4 through the water inlet 5, and then filter the impurities in the cooling water through the filter cartridge 7. The filtered cooling water then flows into the cooling box 2 through the connecting pipe. The cooling box 2 then isolates the cooling water through the partition 3, so that the cooling water cools the hot fluid inside the tank body 1 through the cooling pipe. The used cooling water then flows into the water tank 18 through the connecting pipe. When it is necessary to clean the filter cartridge 7, start the reduction motor 13 to drive the turntable 14 to rotate, and the turntable 14 is driven by the slide bar. 15 pushes the square sleeve 16 to drive the transmission sleeve 10 to rotate back and forth, and the transmission sleeve 10 then drives the scraper 11 to rotate to scrape impurities on the surface of the filter cartridge 7. At the same time, the water pump 19 is started. The water pump 19 injects the cooling water inside the water tank 18 into the interior of the transmission sleeve 10 through the water inlet pipe 20, the three-way valve 21 and the folded hose 17, so that the transmission sleeve 10 sprays the cooling water through the flushing head 12 to flush the interior of the filter cartridge 7, further removing impurities from the mesh of the filter cartridge 7. At the same time, the drain valve pipe 6 is opened to discharge the clean impurities through the guide plate 8, thereby achieving the advantage of easy cleaning.
