Device and process for preparing barium sulfate by fluidized roasting barite

Abstract

The invention relates to the technical field of barium sulfate roasting preparation, and in particular, relates to a device and process for preparing barium sulfate through fluidized roasting barite. The device comprises a roasting furnace; a supporting frame is arranged at the bottom of the roasting furnace, two sets of supporting plates are arranged at the top of the supporting frame, and a smoke exhaust mechanism is arranged at one end of the roasting furnace; and the top of the roasting furnace is provided with a drying mechanism. The device has the beneficial effects that by arranging the drying mechanism, due to the fact that a hollow pipe is inserted into the roasting furnace, high-temperature heat in the roasting furnace can enter a box body through the hollow pipe, and at the moment, the temperature of a heat conduction cover at the top of the box body suddenly rises; and due to the fact that a heat conduction layer at the bottom of a teakettle makes large-area contact with the heat conduction cover, water in the teakettle can be heated and have the temperature rising, then a drainage head is turned on to enable high-temperature hot water in the teakettle to enter the drying cylinder through a through pipe, wet objects are placed in a containing groove, and the high-temperature hot water in the drying cylinder can dry the wet objects, and the multifunctionality of the roasting furnace is improved favourably.

Description

technical field [0001] The invention relates to the technical field of barium sulfate roasting preparation, in particular to a device and a process for preparing barium sulfate by fluidized roasting barite. Background technique [0002] Barium sulfate is a high-density gastrointestinal contrast agent used as a drug. It can be made into suspensions in different proportions and used alone, but it is usually used together with low-density gas to achieve the purpose of double contrast. It is often used for gastrointestinal contrast. According to domestic users According to reports, barium sulfate with uneven thickness is better than fine and uniform barium sulfate, and it should be used with caution in intestinal fistula formation and certain intestinal diseases that are prone to perforation, such as appendicitis, diverticulum, ulcerative enteritis, and parasitic infections. [0003] It is technically feasible to use fluidization technology for barite reduction roasting. The par...

Problems solved by technology

[0004] When barite is roasted in the roaster, smoke will be generated, and the smoke will be accompanied by impurity particles. The current roaster lacks a mechanism to filter the smoke and then discharge it, and the existing roaster can only be roasted and cannot perform other work. , poor functionality
