Description

TECHNICAL FIELD

[0001] The present scheme belongs to the field of industrial salt processing, and particularly relates to an industrial salt magnesium ion removal device. BACKGROUND

[0002] Industrial salt is a basic raw material for the chemical industry, and its main components include sodium chloride and sodium nitrite. Industrial salt plays an important role in the chemical industry, and many basic chemical products such as hydrochloric acid, caustic soda, soda ash, ammonium chloride and chlorine are produced using industrial salt as raw material. In addition, industrial salt can also be used in printing and dyeing, leather making and textile industries as a dyeing aid.

[0003] According to the search, in the utility model patent with the authorization announcement number CN217051663U, a crude salt water magnesium removal device is disclosed, which comprises a chemical aid setting agent device, a salt bucket, a crude salt water flow tank, a front curved channel, a blending liquid concentration tank, a rear curved channel, a parallel flow tank and a first clarification barrel connected in sequence through pipelines; the front curved channel is provided with a lime milk pipeline interface; the chemical aid setting agent device comprises a setting agent tank, a setting agent pump and a setting agent high tank connected in sequence, the setting agent tank is provided with a setting agent adding port and a refined salt water adding port and is provided with stirring, the setting agent high tank outlet pipeline is divided into two routes, one route is connected to the blending liquid concentration tank, and the other route is divided into two routes and connected to the setting agent solution adding ports of the parallel flow tank. The use of the device can improve the magnesium removal effect of crude salt water, reduce the internal scarring of the equipment, stabilize the production conditions of heavy sodium carbonate, reduce production consumption and improve product quality.

[0004] However, in the existing technology, when industrial salt is processed, magnesium ions need to be removed, that is, industrial salt is mixed into an aqueous solution and mixed with lime milk, so that magnesium ions react with lime milk to precipitate. These reactions are all carried out in a sedimentation tank, which also causes new materials to be mixed with old materials during the reaction process. In order to ensure complete reaction, a longer time is needed to wait for the complete precipitation of magnesium ions in industrial salt, which greatly delays the processing progress. In addition, due to the different specific gravities of various substances in the industrial salt aqueous solution, stratification and other situations are inevitable, which also makes it difficult for simple stirring to sufficiently accelerate the reaction process of magnesium ions and lime milk. Utility model content

[0005] The purpose of the present scheme is to provide an industrial salt magnesium ion removal device to solve the problems of long magnesium ion precipitation separation time and inability to take materials in time in the existing technology, and to solve the problem of slow magnesium ion and lime milk reaction rate.

[0006] In order to achieve the above object, the present scheme provides an industrial salt magnesium ion removal device, comprising a mixing tank, the bottom of the mixing tank is provided with supporting legs, a plurality of mixing tanks are provided adjacently side by side, the top of the mixing tank is provided with a feeding port, the bottom of the mixing tank is provided with a discharge pipe, a conveying pump is arranged between two adjacent mixing tanks, one end of the conveying pump is connected with the discharge pipe of one of the mixing tanks through a liquid inlet pipe, and the other end of the conveying pump is connected with the feeding port of the other mixing tank through a liquid outlet pipe, a stirring mechanism is arranged at the upper end of the interior of each mixing tank, and a filtering mechanism is arranged at the bottom of the mixing tank.

[0007] The principle of the present scheme is that when in use, the aqueous solution of industrial salt and lime milk are poured from the feeding port above the outermost mixing tank, and then the stirring mechanism operates to stir and mix the industrial salt and lime milk to allow them to fully contact and react, the magnesium ions in the industrial salt will produce precipitates on the filtering mechanism after reacting with the lime milk, and the conveying pump will extract the unreacted industrial salt and the completely reacted industrial salt into the next mixing tank for further reaction until the magnesium ions in the industrial salt are completely removed and discharged from the discharge pipe of the mixing tank on the other side.

[0008] The technical effect of the present scheme is that through the arrangement of multiple mixing tanks, multiple-stage reaction operation is performed on the industrial salt, which not only ensures the completeness of the removal of magnesium ions in the industrial salt, but also allows the industrial salt from which the magnesium ions have been completely removed to be taken out in time during the reaction process of removing the magnesium ions, and only the unreacted industrial salt remains in the mixing tank for continuous reaction, thereby improving the removal efficiency of magnesium ions.

[0009] Further, a feeding pipe is arranged on the top of each mixing tank. Through the feeding pipe, lime milk can be supplemented into each mixing tank.

Through the rotation of the stirring blades, the lime milk and industrial salt in the mixing tank are stirred, thereby accelerating the reaction rate of the lime milk and industrial salt.

[0011] Further, a spiral blade is arranged on the bottom of the stirring shaft. Through the spiral blade, the material at the bottom of the mixing tank is lifted upwards while being stirred with the lime milk and industrial salt, thereby providing vertical conveying operation of the material in the mixing tank to allow the materials at different heights to fully contact, thereby improving the reaction rate between the materials.

[0012] Further, the filtering mechanism comprises a mounting seat, which is mounted on the outer wall of the mixing tank, and a cavity is formed on the outer side of the mounting seat, the cavity penetrating into the mixing tank, a plug plate is arranged in the cavity, the end outer wall of the plug plate corresponding to the inner wall of the mixing tank, an installation groove corresponding to the inner cavity of the mixing tank is formed on the plug plate, a filter screen is mounted in the installation groove, a sealing plate is mounted on the end of the plug plate away from the filter screen, the sealing plate is detachably mounted on the mounting seat, and a handle is mounted on the sealing plate. The precipitate after the magnesium ions are precipitated is blocked by the filter screen, so that the industrial salt with removed magnesium ions or the industrial salt without removed magnesium ions can pass through the filter screen and enter the next mixing tank or be directly discharged; meanwhile, the detachable mounting of the sealing plate facilitates the taking out of the filter screen from the mixing tank and facilitates the cleaning and replacement of the filter screen.

[0013] Further, a supporting seat is mounted on the inner wall of the mixing tank and arranged on the bottom of the plug plate. The supporting seat supports the plug plate in the mixing tank.
