Description

Technical Field

[0001] The utility model relates to the technical field of crystallization devices, in particular to a sodium acetate preparation crystallization device. Background Art

[0002] Sodium acetate is a colorless and transparent crystal with a wide range of uses. It can be used as an esterifying agent for organic synthesis, as well as photographic drugs, medicines, printing and dyeing mordants, buffers, chemical reagents, meat preservation, pigments, tanning and many other aspects. Anhydrous sodium acetate is divided into industrial grade, food grade, medicinal grade and reagent grade. Its production method is to prepare sodium acetate solution by the reaction of soda ash and acetic acid. The sodium acetate solution is crystallized and evaporated to obtain sodium acetate crystals. When the existing sodium acetate is prepared, the water in the sodium acetate is evaporated by evaporation. After the evaporation is completed, the sodium acetate is generally left to stand and cooled and crystallized by air cooling or water cooling. In this process, the cooling and crystallization of sodium acetate is slow, resulting in low crystallization efficiency. Therefore, we propose a sodium acetate preparation crystallization device to solve the above-mentioned problems. Utility Model Content

[0003] In order to overcome the problem that the water in the existing sodium acetate is evaporated by evaporation during the preparation, the sodium acetate is generally left to stand after the evaporation is completed, and the sodium acetate is cooled and crystallized by air cooling or water cooling. In this process, the cooling and crystallization of the sodium acetate is slow, resulting in a low crystallization efficiency.

[0004] The technical scheme of the utility model is: a sodium acetate crystal preparation device, comprising a load-bearing component, a lifting component, a placing component, a stirring component and a filtering component; a placing component for placing sodium acetate and water for preparing crystals is installed on the upper end of the load-bearing component, a lifting component for driving the stirring component to move up and down and fixedly connected to the load-bearing component at the lower end is installed on one side of the placing component, a stirring component for stirring and mixing sodium acetate and water is installed at one end of the lifting component, and a filtering component that can slide and is used for crystal precipitation for solid-liquid separation is provided at the inner bottom of the placing component.

[0005] Preferably, during the stirring and mixing process, the sodium acetate solution inside the crystallization tank body is heated by driving the heater to reach a supersaturated state, and during the heating process, the sodium acetate solution also needs to be continuously stirred to avoid the situation where the local concentration is too high or too low. When the heating is completed, the L-shaped telescopic sleeve drives the stirring rod to move upward to move out of the crystallization tank body. Then, when the sodium acetate solution reaches a supersaturated state, the heater is turned off, and clean water is poured into the guide pipe through the water inlet pipe and enters the water storage pipe. Through the action of the cooler, the clean water temperature is reduced, and the sodium acetate solution is cooled. As the temperature decreases, the solubility of sodium acetate gradually decreases, and the solute in the supersaturated solution begins to precipitate to form sodium acetate crystals. In this process, the thermometer goes deep into the crystallization tank body to perform real-time temperature detection, and then the temperature inside the crystallization tank body is adjusted in time through the control of the display panel to avoid affecting the efficiency of sodium acetate crystallization.

[0006] Preferably, the load-bearing component includes a load-bearing platform and a heater. A circular groove for installing the component is provided on the top of the load-bearing platform, and a rectangular groove for installing the heater is provided at the bottom of the load-bearing platform where the circular groove is provided. The heater is positioned and connected to the load-bearing platform through the rectangular groove, and the crystallization tank body is positioned and connected to the load-bearing platform through the circular groove. When sodium acetate and water are mixed to prepare a sodium acetate solution, the sodium acetate solution inside the crystallization tank body is heated by driving the heater to reach a supersaturated state.

The telescopic column is provided inside the L-shaped telescopic sleeve, the cylinder is installed on the upper end of the L-shaped telescopic sleeve, and an installation hole for installing a stirring assembly is provided at the end of the L-shaped telescopic sleeve away from the telescopic column.

[0008] Preferably, the placement assembly includes a crystallization tank body, a thermometer, a display panel, a water storage pipe, a guide pipe, a water inlet pipe and a sealing ring cover, a thermometer for penetrating into the interior of the crystallization tank body for temperature detection is installed on one side of the exterior of the crystallization tank body, a display panel fixedly connected to the crystallization tank body is installed on one side of the thermometer, and multiple groups of chutes for sliding of the filter assembly are arranged around the interior of the crystallization tank body, a certain amount of sodium acetate and water are poured into the crystallization tank body, when the heating is completed, when the sodium acetate solution reaches a supersaturated state, the heater is turned off, and clean water is poured into the guide pipe through the water inlet pipe and enters the water storage pipe, through the action of the cooler, the clean water temperature is reduced, and the sodium acetate solution is cooled, and as the temperature decreases, the solubility of sodium acetate gradually decreases, and the solute in the supersaturated solution begins to precipitate to form sodium acetate crystals.

[0009] Preferably, a sealing ring cover is installed at the upper end of the crystallization tank body, a plurality of water storage pipes are arranged around the interior of the crystallization tank body, a cooler is installed at the bottom of the water storage pipe, a guide pipe is installed at the upper end of the water storage pipe, a circular hole is opened on the sealing ring cover, and the water inlet pipe passes through the circular hole and is fixedly connected with the guide pipe. During this process, the thermometer penetrates into the interior of the crystallization tank body for real-time temperature detection, and then the temperature inside the crystallization tank body is adjusted in time through the control of the display panel to avoid affecting the efficiency of sodium acetate crystallization.

[0010] Preferably, the stirring assembly includes a motor, a rotating column and a stirring rod. The motor is installed on the upper end of the rotating column. Multiple groups of stirring rods are installed linearly around the outside of the rotating column. The rotating column is fixedly connected to the L-shaped telescopic sleeve through the mounting hole. The rotating column is driven by the motor to drive the stirring rod to stir and mix the sodium acetate and water inside the crystallization tank to prepare a sodium acetate solution. During the heating process, the sodium acetate solution needs to be continuously stirred to avoid local concentrations that are too high or too low.

[0011] Preferably, the filter assembly includes a filter plate, a filter membrane and an arc-shaped slider. The filter membrane is installed at the lower end of the filter plate. A plurality of groups of arc-shaped sliders are installed around the outside of the filter plate. The arc-shaped slider drives the filter plate and the filter membrane to slide along the slide groove and connect with the crystallization tank body. A driver is installed inside the arc-shaped slider.

[0012] Beneficial effects of the utility model:

[0013] 1. According to the existing sodium acetate in the past, when preparing, the water in the sodium acetate is evaporated by evaporation. After the evaporation is completed, the sodium acetate is generally left to stand and cooled and crystallized by air cooling or water cooling. In this process, the cooling and crystallization of the sodium acetate is slow, resulting in low crystallization efficiency. The difference is that during the stirring and mixing process, the sodium acetate solution in the crystallization tank is heated by the heater to reach a supersaturated state. During the heating process, the sodium acetate solution also needs to be continuously stirred to avoid the situation where the local concentration is too high or too low. When the heating is completed, The L-shaped telescopic sleeve drives the stirring rod to move upward to move out of the crystallization tank. Then, when the sodium acetate solution reaches a supersaturated state, the heater is turned off, and clean water is poured into the diversion pipe through the water inlet pipe and into the water storage pipe. Through the action of the cooler, the clean water temperature is reduced, and the sodium acetate solution is cooled. As the temperature decreases, the solubility of sodium acetate gradually decreases, and the solute in the supersaturated solution begins to precipitate to form sodium acetate crystals. In this process, the thermometer goes deep into the crystallization tank to perform real-time temperature detection, and then the temperature inside the crystallization tank is adjusted in time through the control of the display panel to avoid affecting the efficiency of sodium acetate crystallization.

[0014] 2. After the crystals are precipitated, the driver drives the filter plate and the filter membrane to move upward along the slide to a suitable height. The filter plate then performs preliminary solid-liquid separation on the precipitated crystals, while the filter membrane can further separate the liquid from smaller crystalline solids to avoid omissions. After the filtration is completed, the crystals on the filter plate and the filter membrane can be removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figure 3-5In the present embodiment, the placement component 3 includes a crystallization tank body 301, a thermometer 302, a display panel 303, a water storage pipe 304, a guide pipe 305, a water inlet pipe 306 and a sealing ring cover 307. A thermometer 302 that penetrates into the crystallization tank body 301 for temperature detection is installed on one side of the outer side of the crystallization tank body 301, and a display panel 303 fixedly connected to the crystallization tank body 301 is installed on one side of the thermometer 302.

Multiple groups of stirring rods 403 are linearly installed around the outside of the rotating column 402. The rotating column 402 passes through the mounting hole 204 and is fixedly connected with the L-shaped telescopic sleeve 202. The filtering component 5 includes a filter plate 501, a filter membrane 502 and an arc-shaped slider 503. The filter membrane 502 is installed at the lower end of the filter plate 501.

A driver (the driver model is AQMD6030BLS-E3) is installed inside the arc-shaped slider 503.

[0024] During operation, the crystallization tank body 301 is positioned and connected with the load-bearing platform 101 through the circular groove 102, and then a certain amount of sodium acetate and water are poured into the crystallization tank body 301. After the sodium acetate and water are all poured into the crystallization tank body 301, the L-shaped telescopic sleeve 202 drives the stirring rod 403 along the telescopic column 201 to move downward to the deep crystallization tank body 301 through the drive of the cylinder 203, and then the rotating column 402 drives the stirring rod 403 to stir and mix the sodium acetate and water inside the crystallization tank body 301 through the drive of the motor 401 to prepare a sodium acetate solution. During the stirring and mixing process, the sodium acetate solution inside the crystallization tank body 301 is heated through the drive of the heater 104 to make it reach a supersaturated state. In the heating process, the sodium acetate solution also needs to be continuously stirred to avoid the situation where the local concentration is too high or too low.

[0025] After heating is completed, the L-shaped telescopic sleeve 202 drives the stirring rod 403 to move upward to move out of the crystallization tank body 301. Then, when the sodium acetate solution reaches a supersaturated state, the heater 104 is turned off, and clean water is poured into the guide pipe 305 through the water inlet pipe 306 and enters the water storage pipe 304. Through the action of the cooler, the clean water temperature is reduced, and the sodium acetate solution is cooled. As the temperature decreases, the solubility of sodium acetate gradually decreases, and the solute in the supersaturated solution begins to precipitate to form sodium acetate crystals. In this process, the thermometer 302 goes deep into the crystallization tank body 301 to perform real-time temperature detection, and then the temperature inside the crystallization tank body 301 is adjusted in time through the control of the display panel 303 to avoid affecting the efficiency of sodium acetate crystallization.

[0026] After the crystals are precipitated, the driver drives the filter plate 501 and the filter membrane 502 to move upward along the slide groove 309 to a suitable height. Then the filter plate 501 performs preliminary solid-liquid separation on the precipitated crystals, and the filter membrane 502 can further separate the liquid from smaller crystalline solids to avoid omission. After the filtration is completed, the crystals on the filter plate 501 and the filter membrane 502 can be taken out.

[0027] Through the above steps, during the stirring and mixing process, the sodium acetate solution inside the crystallization tank body 301 is heated by the drive of the heater 104 to make it reach a supersaturated state. During the heating process, the sodium acetate solution also needs to be continuously stirred to avoid the situation where the local concentration is too high or too low. After the heating is completed, the L-shaped telescopic sleeve 202 drives the stirring rod 403 to move upward to move out of the crystallization tank body 301. Then, when the sodium acetate solution reaches a supersaturated state, the heater 104 is turned off, and clean water is poured into the guide pipe 305 through the water inlet pipe 306 and enters the water storage pipe 304. Through the action of the cooler, the clean water temperature is reduced, and the sodium acetate solution is cooled. As the temperature decreases, the solubility of sodium acetate gradually decreases, and the solute in the supersaturated solution begins to precipitate to form sodium acetate crystals. In this process, the thermometer 302 goes deep into the crystallization tank body 301 to perform real-time temperature detection, and then through the control of the display panel 303, the temperature inside the crystallization tank body 301 is adjusted in time to avoid affecting the efficiency of sodium acetate crystallization.
