Spraying and powder making device

Abstract

Disclosed is a spraying and powder making device. The spraying and powder making device comprises a spraying tower, a first cyclone separator, a shell-and-tube heat exchanger, a high-pressure draught fan, a second cyclone separator and an air inlet pipe, wherein a first air outlet is formed in the upper end of the spraying tower; a first air inlet, a second air outlet and a first material return opening are formed in the first cyclone separator, and the first air inlet is connected with the first air outlet of the spraying tower; the upper end of the shell-and-tube heat exchanger is connected with the second air outlet of the first cyclone separator, and a discharge port is formed in the lower end of the shell-and-tube heat exchanger; an air absorbing opening and a blowing opening are formed in the high-pressure draught fan, and the air absorbing opening is in butt-joint connection with the discharge port of the shell-and-tube heat exchanger; a second air inlet and a second material return opening are formed in the second cyclone separator; a pipe opening at one end of the air inlet pipe stretches to the interior o a cavity in the lower portion of the spraying tower, the other end of the air inlet pipe is connected with the blowing opening of the high-pressure draught fan, and the second air inlet, the second material return opening and the first material return opening are respectively and fixedly connected with the surface of the pipe body of the air inlet pipe. The spraying and powder making device avoids product loss and pollution between environments, improves cooling efficiency and working efficiency and reduces manufacturing cost.

Description

technical field [0001] The invention relates to a spray powder making device. Background technique [0002] There are many types of spray powder making devices at present. The current spray powder making technology heats the material to make it in a fluid state. After the hot material is atomized by the atomization wheel, the material and the air flow are the same as the upward and downward flow of wind to cool the material. The heat is discharged from the air outlet to achieve the purpose of pulverization and cooling; but the cooling efficiency is low, and only fine powder can be produced; materials are often taken out by the wind at the air outlet, causing material damage and environmental pollution; dust in the air of the production environment Pollution to products, especially in dusty weather will aggravate the pollution of products. Contents of the invention [0003] The object of the present invention is to solve the shortcomings of the existing spray powder making...
