Annular drum-type evaporation barrel for realizing uniform shunting of gas-liquid two-phase refrigerants

Abstract

The invention relates to the technical field of evaporator evaporation barrels, in particular to an annular drum-type evaporation barrel for realizing uniform shunting of gas-liquid two-phase refrigerants. The annular drum-type evaporation barrel comprises an outer barrel, an inner barrel is arranged in the outer barrel, a liquid blocking assembly is welded outside the inner barrel, a liquid inlet assembly is mounted on the position, close to the top, of the outer wall of the side face of the inner barrel through bolts, and the liquid inlet assembly comprises a liquid inlet pipe. Through holes distributed in an annular structure at equal intervals are formed in the position, close to the bottom, of the inner wall of the side face of the liquid inlet pipe, a liquid inlet is formed in the outer wall of one side of the liquid inlet pipe, a connecting pipe is integrally formed in the liquid inlet, the top end of the connecting pipe is in threaded connection with a connecting sleeve, and a filter screen is inserted into the connecting sleeve. The device has the beneficial effects that a refrigerant can uniformly flow on the outer wall of the side surface of the inner barrel through the liquid inlet pipe, and the refrigerant can be shunted by a shunting block when flowing out of the liquid inlet pipe, so that the refrigerant is uniformly distributed on the outer wall of the inner barrel; and meanwhile, liquid baffles are arranged layer by layer in a staggered manner, so that the refrigerant uniformly flows on the outer wall of the side surface of the inner barrel.

Description

technical field [0001] The invention relates to the technical field of evaporator barrels, in particular to an annular drum-type evaporation barrel that realizes uniform flow distribution of gas-liquid two-phase refrigerants. Background technique [0002] The ice machine is a kind of refrigeration mechanical equipment that generates ice after water is cooled by the refrigerant of the refrigeration system through the evaporator. The refrigeration system is used to use water as a carrier to produce ice after passing through a certain device in the electrified state. The ice machine is widely used. Applied to our country's industry and commerce, etc., the ice machines currently on the market use evaporation barrels as evaporation devices to obtain ice. [0003] Chinese Patent No. CN210014590U provides a spiral pipeline type evaporating barrel for flake ice machines, including a drive motor, a reducer and an outer cylinder, the drive motor and the reducer are fixed on the outer ...
