Problems solved by technology

[0011] 1. The drying, crushing and grading of the existing precipitated barium sulfate are all realized by a single device and then combined to form a production line. If this is done, the investment will be large, the functions of the equipment will be repeated, and the area will be large.
[0012] 2. High energy consumption and large power consumption; the industry standard produces 1 ton of BaSO 4 Energy consumption is 0.8 tons of standard coal
[0013] 3. The quality of the product is poor; due to the combination of a single device, it is difficult to achieve a complete seal between the devices, and it is easy to be polluted by foreign impurities, which affects the quality of the product
[0014] 4. High production cost
[0015] 5. The labor intensity is high, and manual transfer is required between each process, which also causes the product to be polluted

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] As can be seen from the accompanying drawings, the present invention is the drying, pulverizing, grading process and equipment of precipitated barium sulfate, which is to synthesize the drying, pulverizing, and grading processes of precipitated barium sulfate filter cake in a fully enclosed container to concentrate and complete the pulverization , low-temperature drying, and grading processes, and the pulverized precipitated barium sulfate powder is driven by the circulating air flow, and after low-temperature drying and grading, it becomes the required high-quality precipitated barium sulfate product. The specific process is: use the water vapor saturation under different temperature, pressure and humidity conditions, use the waste heat of tail exhaust gas (below 200 ℃) to carry out the low-temperature drying process of fully enclosed circulating air flow, and t...

Abstract

A pulverizing, low-temp airflow drying and classifying process for preparing the precipitated barium sulfate features that said three technological steps and their units are integrated vertically in a sealed container.

Description

technical field [0001] The present invention relates to a kind of production equipment of precipitated barium sulfate, mainly refers to a kind of for producing precipitated barium sulfate process, is used for directly processing semi-finished product precipitated barium sulfate cake (solid content 70%) into the qualified finished product of different granularity ( Dry powder) integrated special equipment. Background technique [0002] Precipitated barium sulfate is an important basic inorganic salt product in the chemical industry. There are two important processes in various production methods, namely drying and crushing. The precipitated barium sulfate slurry obtained by different processes must undergo solid-liquid separation. The obtained filter cake, that is, the semi-finished product of precipitated barium sulfate, can become a powdery product with a water content of less than 0.3% and a fineness of 325 mesh to 3000 mesh only after drying, crushing and grading. At pre...
