Technical Field

[0001] The utility model relates to the technical field of condensing devices, in particular to a condensing device for preparing sodium chloride. Background Art

[0002] Sodium chloride is a common inorganic salt, also known as table salt. It is colorless crystal in solid state, has high solubility, and can be completely dissolved in water. Sodium chloride is often used as a seasoning in food processing and is also one of the electrolytes necessary for human physiology. In addition, sodium chloride is also widely used in industrial production, pharmaceutical preparation, scientific research experiments and other fields. Sodium chloride can be prepared by a variety of methods, one of which is to use a condensing device. When the existing condensing device cools the sodium chloride, the cooling efficiency is not high, resulting in the product in the sodium chloride preparation process cannot be completely condensed, thereby affecting the purity and yield of the product; therefore, we propose a condensing device for sodium chloride preparation to solve the above-mentioned problems. Utility Model Content

[0003] In order to overcome the problem that the product in the sodium chloride preparation process cannot be completely condensed due to low cooling efficiency when the existing condensing device cools the sodium chloride, thereby affecting the purity and yield of the product.

[0004] The technical scheme of the utility model is: a condensing device for preparing sodium chloride, comprising a placing component, an introduction component, an outlet component, a filtering component and a receiving component; an introduction component for introducing hydrogen chloride gas is installed at the upper end of the placing component, an outlet component for outlet sodium chloride solution generated by the reaction of hydrogen chloride gas and sodium oxide solution is installed at one side of the placing component, a receiving component for receiving precipitated sodium chloride crystals is arranged below the outlet component, and a filtering component for solid-liquid separation of sodium chloride crystals is installed at the inner upper end of the receiving component.

[0005] Preferably, first put the coolant into the placement tube, then fix the outlet tube to the round-bottom beaker through the connecting hole, then pick up the vertical plate, position and connect it with the clamping groove through the clamping block, place the funnel-shaped filter plate on the receiving cup, then pick up the sealing round cover, pour the sodium oxide solution into the round-bottom beaker, and then close the sealing round cover and the round-bottom beaker. During this process, the rubber sealing gasket increases the sealing performance to prevent air from entering and affecting the chemical reaction. Finally, the air pipe of the hydrogen chloride gas is positioned and connected to the introduction tube through the connecting ring sleeve, so as to facilitate the transportation of hydrogen chloride gas into the round-bottom beaker through the introduction tube. During this process, the sealing ring prevents air leakage, and the hydrogen chloride gas in the round-bottom beaker reacts with the sodium oxide solution to form gas that enters the outlet tube. Then, through the action of the coolant, the temperature of the gas is reduced and gradually changes from gas to liquid. Then, through the action of the temperature controller, the temperature is reduced to below the solubility of sodium chloride, so that the sodium chloride begins to precipitate in the form of crystals.

[0006] Preferably, the placement component includes a round-bottom beaker, a sealed round cover and a rubber sealing gasket. The sealed round cover is installed on the upper end of the round-bottom beaker, and a rubber sealing gasket for increasing the sealing performance is installed in the middle of the lower end of the sealed round cover. The round-bottom beaker is provided with a connecting hole for installing the export component. By picking up the sealed round cover, the sodium oxide solution is poured into the round-bottom beaker, and then the sealed round cover and the round-bottom beaker are closed. The rubber sealing gasket increases the sealing performance to prevent air from entering and affecting the chemical reaction.

[0007] Preferably, the introduction component includes a connecting ring sleeve, an introduction tube and a sealing ring. A sealing ring is provided at the connection between one end of the introduction tube and the sealing round cover. A connecting ring sleeve is installed at the end of the introduction tube away from the sealing ring. The gas pipe of the hydrogen chloride gas is positioned and connected to the introduction tube through the connecting ring sleeve, so that the hydrogen chloride gas is conveniently transported into the round-bottom beaker through the introduction tube. In this process, the sealing ring prevents gas leakage and improves the sealing performance.

[0008] Preferably, the export assembly includes an export tube, a placement tube, a connecting frame and a temperature controller. The export tube is fixedly connected to the round-bottom beaker through a connecting hole. The interior of the export tube is provided with a placement tube for placing a coolant. The coolant is placed in the placement tube, and then the export tube is fixedly connected to the round-bottom beaker through the connecting hole. Then, the hydrogen chloride gas in the round-bottom beaker reacts with the sodium oxide solution to form a gas that enters the export tube.

[0009] Preferably, a plurality of connecting frames are installed around the two ends of the placement tube, and the connecting frames drive the placement tube to be fixedly connected with the outlet tube. A temperature controller for controlling the temperature to increase the yield of sodium chloride is installed on the outside of the outlet tube. Through the action of the coolant, the temperature of the gas is reduced and gradually changes from gaseous to liquid. Finally, through the action of the temperature controller, the temperature is reduced to below the solubility of sodium chloride, and the sodium chloride begins to precipitate in the form of crystals.

[0010] Preferably, the filter assembly includes a funnel-shaped filter plate, a clamping block and a vertical plate. The funnel-shaped filter plate is evenly provided with a plurality of filter holes for solid-liquid separation of sodium chloride crystals. The outer side of the funnel-shaped filter plate is symmetrically installed with a clamping block. The upper end of the clamping block is installed with a vertical plate for lifting the funnel-shaped filter plate. The vertical plate is first picked up, and then the clamping block is positioned and connected with the clamping groove, and the funnel-shaped filter plate is placed on the receiving cup. When sodium chloride begins to precipitate in the form of crystals and falls onto the funnel-shaped filter plate, solid-liquid separation is performed through the filter holes, and the liquid flows into the receiving cup, and the solid remains on the funnel-shaped filter plate. After all is completed, the clamping block is lifted by the vertical plate to remove the sodium chloride crystals on the funnel-shaped filter plate.

[0011] Preferably, the receiving component includes a receiving cup, a liquid outlet pipe and a sealing cover. The inner wall of the receiving cup is symmetrically provided with connecting grooves for positioning the connecting block. The liquid outlet pipe is installed at the lower end of the outside of the receiving cup. The sealing cover is provided on the outside of the end of the liquid outlet pipe away from the receiving cup. When the liquid flows into the receiving cup, the sealing cover is loosened to pour out the liquid in the receiving cup through the liquid outlet pipe for storage.

[0012] Beneficial effects of the utility model:

[0013] 1. According to the previous condensation device, when cooling sodium chloride, the cooling efficiency is not high, resulting in the inability to completely condense the product in the sodium chloride preparation process, thereby affecting the purity and yield of the product.

In this process, the rubber seal The gasket increases the sealing to prevent air from entering and affecting the chemical reaction. Finally, the gas pipe of the hydrogen chloride gas is positioned and connected to the introduction pipe through the connecting ring sleeve, so as to facilitate the transportation of the hydrogen chloride gas into the round-bottom beaker through the introduction pipe. In this process, the sealing ring prevents air leakage. The hydrogen chloride gas in the round-bottom beaker reacts with the sodium oxide solution to form a gas that enters the outlet pipe. Then, through the action of the coolant, the temperature of the gas is reduced and gradually changes from gas to liquid. Then, through the action of the temperature controller, the temperature is reduced to below the solubility of sodium chloride, and thus the sodium chloride begins to precipitate in the form of crystals.

[0014] 2. When sodium chloride begins to precipitate in the form of crystals and falls onto the funnel-shaped filter plate, solid-liquid separation is performed through the filter holes, the liquid flows into the receiving cup, and the solid remains on the funnel-shaped filter plate. After everything is completed, lift the clamping block through the vertical plate to take out the sodium chloride crystals on the funnel-shaped filter plate, then loosen the sealing cover and pour out the liquid in the receiving cup through the liquid outlet pipe for storage.

[0023] See also Figure 4-5In this embodiment, the filter assembly 4 includes a funnel-shaped filter plate 401, a clamping block 403 and a vertical plate 404. The funnel-shaped filter plate 401 is evenly provided with a plurality of filter holes 402 for solid-liquid separation of sodium chloride crystals.

[0024] When working, first put the coolant into the placement tube 302, then fix the outlet tube 301 with the round bottom beaker 101 through the connection hole 102, then pick up the vertical plate 404, and position and connect it with the clamping groove 502 through the clamping block 403, place the funnel-shaped filter plate 401 on the receiving cup 501, then pick up the sealing round cover 103, pour the sodium oxide solution into the round bottom beaker 101, and then close the sealing round cover 103 and the round bottom beaker 101.

Finally The gas pipe of hydrogen chloride gas is positioned and connected with the introduction pipe 202 through the connecting ring sleeve 201, so that the hydrogen chloride gas is conveniently transported into the round-bottom beaker 101 through the introduction pipe 202. In this process, the sealing ring 203 prevents gas leakage.
