[0002] Barium chloride is an inorganic compound with the chemical formula BaCI2. It is a white crystalline solid with high solubility in water. It is widely used in the preparation of barium salts, metallic barium and other compounds. The process for industrial preparation of barium chloride is as follows: barite ore (containing BaCO3) is roasted at high temperature using charcoal, and then hydrochloric acid (HCI) solution is added to dissolve it. After the reaction is completed, the produced barium chloride solution is filtered to remove the unreacted solid residue, and finally the barium chloride solution is evaporated and dried to obtain the final barium chloride product.

A plurality of fixed columns 2 are fixedly connected to the bottom end of the filter bin 5. The fixed columns 2 and the bottom outer wall of the vacuum pump 10 are fixedly connected to the base 1.

[0034] Specifically, after the filtration is completed, the annular sealing block 14 is pulled up by the action of the hydraulic rod 16. At this time, the filter bin 5 is connected with the slag storage bin 3, the motor 8 is started, and the rotating shaft 19 drives the arc-shaped scraper 18 on the filter plate 13 to rotate, effectively scraping the barite ore residue remaining on the filter plate 13 into the slag storage bin 3. The whole process is closed, which effectively avoids the long-term exposure of the staff to the working environment containing barium chloride, improves safety and avoids the cumbersome residue treatment process.

[0035] The sealing assembly includes an annular sealing block 14, which is slidably connected to the inside of the side wall of the filter chamber 5. A hydraulic rod 16 is installed on the top outer wall of the annular sealing block 14.
