Embodiment Construction

[0018] Attached below figure 1 For further explanation:

[0019] In the figure, 1 is the furnace, 2 is the heat receiver, 3 is the collector, 4 is the crusher, 5 is the elevator, 6 is the silo, 7 is the uniform feeder, 8 is the refiner, and 9 is the slurry tank. 10 is a non-blocking mud pump, 11 is a hydrocyclone, 12 is a advection sedimentation tank, 13 is a washing mixing tank, 14 is a filtrate tank, 15 is a mud pump, 16 is an acid tank, 17 is a water tank, and 18 is a dewatering tank. In the mud bucket, 19 is a thickener, 20 is a belt conveyor, 21 is a dryer, 22 is a crusher, 23 is a blower, 24 is a cyclone separator, 25 is a bag collector, and 26 is a water heater.

[0020] The fuel provides a heat source for the furnace 1 and heats the heat receiver 2. The heat receiver 2 contains crushed raw ore or fine ore powder. When the temperature in the container rises to 267-870°C and is maintained at 500-870°C, the material undergoes a series of physical and chemical changes, and fin...

Abstract

The invention provides a method and device for extracting and processing refined arsenic disulfide powder with water for medical use, wherein the preparation mainly comprises four steps of purifying, fine grinding, pickling and drying.

Description

Technical field [0001] The invention relates to a production process and equipment for refining and processing water fly realgar powder. According to the requirements of the process and equipment combination, it is possible to produce water fly realgar powder with a realgar content of more than 99% and an arsenic trioxide content of less than 0.17%. The product can be directly used to produce various Chinese patent medicines containing realgar components. Background technique [0002] At present, there is no precedent for industrial production of realgar powder for medicinal water in my country. Most production units that use realgar powder for medicinal water buy high-grade raw ore from the market, which is crushed and water-blown. This production process It has been applied for more than a thousand years. There are also units that produce proprietary Chinese medicines that purchase higher-grade flotation concentrates from the market and use them directly in production. In this ...
