Description

Technical Field

[0001] The invention relates to the technical field of hydrochloric acid preparation, in particular to a hydrochloric acid preparation device. Background Art

[0002] The scientific name of hydrochloric acid is hydrochloric acid, which is an aqueous solution of hydrogen chloride and a monoprotic acid. Hydrochloric acid is a strong acid with extremely strong volatility. Therefore, when a container containing concentrated hydrochloric acid is opened, acid mist can be seen on the top. It is small droplets of hydrochloric acid produced by the volatilization of hydrogen chloride and the combination of water vapor in the air. Hydrochloric acid is a common chemical. Under normal circumstances, the mass fraction of hydrogen chloride in concentrated hydrochloric acid is about 38%. At the same time, the main component of gastric acid is also hydrochloric acid. Some drugs will add hydrochloric acid to them to make the drugs into hydrochloride, which is called salt formation in the pharmaceutical field. That is, two molecules in ionic state are combined together by ionic bonds, which can greatly change the physical and chemical properties of the drug.

[0003] At present, in the preparation of hydrochloric acid, the batching hopper is glued to the upper part of the batching pipe, which is convenient for placing the required ingredients in the batching hopper for mixing and proportioning according to the needs when in use. The rotating handle bolt is installed on the upper part of the batching frame, which is convenient for using the rotating handle to drive the batching frame to rotate when in use, thereby facilitating the mixing of the proportioned materials;

[0004] However, in the actual preparation process, it is still necessary to manually rotate the ingredient rack using a rotary handle to stir the proportioned materials, and in the process of adding ingredients, it is necessary to stop stirring the ingredients.

When the discharge hole 33 on the sixth gear 32 rotates down to the bottom end of the batching hopper 5, the batching hopper 5 can be opened, and then the batching hopper 5 is automatically and intermittently opened to add the proportioning material into the mixing box 2 to prepare hydrochloric acid. After the preparation of hydrochloric acid is completed, the pull sheet 54 can be used to pull one end of the positioning rod 55 out of the positioning hole 57 in the middle, and the handle 50 can be used to rotate the turntable 43 ninety degrees in the clockwise direction so that the discharge pipe 40 , the discharge trough 44 and the discharge port 42 are interconnected, the prepared hydrochloric acid is discharged, and the prepared hydrochloric acid is filtered by the filter plate 46. After the discharge is completed, one end of the positioning rod 55 is pulled out from the upper positioning hole 57, and the turntable 43 is continuously rotated by the handle 50 to lower one end of the positioning rod 55 and insert it into the lower positioning hole 57, and then the handle 48 can be used at the discharge port 42 to rotate one end of the screw rod 47 out of the threaded groove of the fixed frame 45, and the filter plate 46 is pulled out for cleaning or replacement, so that the preparation of hydrochloric acid can be achieved.
