Description

Technical Field

[0001] The utility model relates to the technical field of evaporation crystallization, and particularly relates to a swirling evaporation crystallization device for concentrated mother liquor. Background Technique

[0002] In chemical experiments, mother liquor usually refers to the remaining solution during processes such as solid-liquid separation or precipitate preparation. These solutions contain a relatively high concentration of residual reactants and may need to be treated to avoid environmental pollution or for valuable reuse. Evaporation refers to the phase change process in which a substance transforms from a liquid state to a gaseous state, and crystallization refers to the formation of crystals from a liquid or gaseous state. In chemistry, evaporation refers to the process of heating a solution to make a certain substance in the solution reach its boiling point and volatilize, and crystallization refers to the process in which the solute in the solution reaches supersaturation and precipitates crystals. In chemistry, evaporation and crystallization often occur together because the purpose of evaporation is generally to let the solvent in the solution volatilize, so that a certain solute in the solution reaches supersaturation and thus crystallizes.

[0003] Chinese Patent Publication No. CN220370469U discloses a mother liquor evaporation crystallization device, which relates to the technical field of crystallization devices and includes a crystallization barrel. A support column is fixedly connected to the outer wall of the bottom of the crystallization barrel. An exhaust port and a discharge port are respectively arranged on the crystallization barrel. A heating plate is installed on the crystallization barrel. A filter box is installed on the outer wall of the top of the crystallization barrel. The filter box is communicated with the crystallization barrel, and a water injection port is opened on the filter box. By setting a filter plate in the utility model, impurities in the mother liquor can be filtered to prevent them from affecting the purity of evaporation crystallization, and the working efficiency of evaporation crystallization is also reduced. A scraping mechanism is set to scrape the impurities on the filter plate to prevent them from adhering to the filter plate all the time and affecting the filtering effect. By setting a stirring mechanism, not only can the evaporation crystallization efficiency of the mother liquor be improved, but also the crystals adhering to the inner wall of the crystallization barrel can be scraped to avoid the crystals adhering to the inner wall of the crystallization barrel and affecting the discharge of the crystals.

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] As Figure 1 、 4As shown in the figure, a swirling evaporation and crystallization device for concentrated mother liquor includes a base 1. On the right side of the top of the base 1, two brackets 2 are fixedly connected, and a device housing 3 is fixedly connected between the two brackets 2. On the left side of the device housing 3, a feed hopper 4 is fixedly connected, and a feed valve 10 is provided at the top of the feed hopper 4. By opening the feed valve 10, the mother liquor can be poured into the device housing 3 through the feed hopper 4. In the middle of the bottom side of the device housing 3, a discharge hopper 11 is fixedly installed, and a discharge valve 8 is fixedly connected to the bottom end of the discharge hopper 11. By opening the discharge valve 8, the crystallized mother liquor can be discharged. At the top of the left bracket 2 among the two brackets 2, a heater 6 is fixedly installed. The heater 6 is composed of a control system and a heating element in the prior art. The heating element is installed on the outer surface of the device housing 3. The heating element is controlled by the control system to generate heat. The heat is transferred to the object to be heated, raising its temperature. By starting the heater 6, the inside of the device housing 3 can be heated. Inside the device housing 3, there is a crystallization assembly 5. The crystallization assembly 5 can make the hot air evenly contact the mother liquor, making the mother liquor reach a saturated state and concentrating it. On the top of the base 1, a purification assembly 9 is provided. The purification assembly 9 can purify the harmful gases generated during the crystallization process to prevent the direct discharge of harmful gases and cause environmental pollution. On one side of the purification assembly 9, an auxiliary assembly 7 is fixedly connected, which can assist the discharged purified gas.

[0027] As Figure 2 , 3 shown, the purification assembly 9 includes a box body 91, a dehumidification net 93, an adsorption net 95 and a high-efficiency filter net 92. The box body 91 is located at the right end of the top side of the base 1. On the inner walls of the top and bottom of the front end of the box body 91, a sealing plate 97 is rotatably connected. Between the left end of the sealing plate 97 and the front end of the box body 91, a handle lock structure of the model MS308-2A commonly used in the prior art is jointly installed. Between the top end of the box body 91 and the device housing 3, a connecting pipe 96 is fixedly installed. Through the connecting pipe 96, the harmful gases in the device housing 3 can be transmitted into the box body 91 and purified. Inside the box body 91, a plurality of clamping blocks 94 are fixedly connected. The dehumidification net 93, the adsorption net 95 and the high-efficiency filter net 92 are respectively slidably connected between the plurality of clamping blocks 94.

[0028] The dehumidification net 93 can adopt a filter net containing compressed quicklime blocks in the prior art. Since the quicklime blocks have strong moisture absorption performance, they are suitable for this scheme. However, the quicklime blocks are only one implementation method of this scheme. For the prior art, any material with similar performance to the quicklime blocks that can be reused can be adopted;

[0029] The adsorption net 95 is an activated carbon adsorption net, which can adsorb a large number of particulate matters in the air. The high-efficiency filter net 92 is used to remove particulate matters, odors, formaldehyde in the harmful gases and perform ultraviolet sterilization and disinfection.

[0030] As can be seen from the above, since the dehumidification net 93, the adsorption net 95 and the high-efficiency filter net 92 are slidably connected to the block 94, when the dehumidification net 93, the adsorption net 95 and the high-efficiency filter net 92 need to be replaced, the corresponding net can be pulled out and replaced.

[0031] like Figure 3 , 5 As shown in , 6, the auxiliary component 7 includes a fan blade 71, and an exhaust pipe 72 is fixedly connected to the right side of the box body 91. The exhaust pipe 72 can discharge the purified air in the box body 91. A fixed plate 74 is fixedly installed in the exhaust pipe 72, and a rotating column 78 is rotatably connected to the middle end of the right side of the fixed plate 74. The right end of the rotating column 78 is fixedly connected to the fan blade 71, and a pulley 73 is fixedly installed on the rotating column 78.

[0032] Furthermore, a motor 79 is fixedly connected to the left end of the top of the device housing 3 , and a rotating column 75 is fixedly installed on the output shaft of the motor 79 . A support frame is installed at the middle end of the top of the device housing 3 .

[0033] Furthermore, the right end of the rotating column 75 passes through the support frame and is fixedly connected to a second pulley 76. The rotating column 75 is rotatably connected to the support frame, and the first pulley 73 and the second pulley 76 are transmission-connected with the same belt 77.

[0034] As can be seen from the above, when the motor 79 is started, the output shaft of the motor 79 drives the rotating column 75 to rotate, and drives the second pulley 76 to rotate, and further drives the pulley 1 73 to rotate through the belt 77, so that the rotating column 78 drives the fan blade 1 71 to rotate, which can assist the purified air to be dissipated through the exhaust pipe 72, preventing the direct discharge of air containing harmful gases and causing unnecessary pollution.

[0035] like Figure 4 , 6 As shown, the crystallization assembly 5 includes a second fan blade 54 , and the second fan blade 54 is rotatably connected to the inner wall of the middle end of the top side of the device housing 3 , and a barrier net 55 is fixedly installed on the inner wall of the middle end of the top side of the device housing 3 .

[0036] Furthermore, a bevel gear 1 51 is fixedly connected to the rotating column 75, and the bevel gear 1 51 is meshingly connected to the bevel gear 2 52, and the bottom end of the bevel gear 2 52 is fixedly connected to a rotating rod 53, which passes through the top end of the device housing 3 and is fixedly connected to the fan blade 2 54, and the rotating rod 53 is rotatably connected to the device housing 3.

[0037] As can be seen from the above, the rotating column 75 drives the bevel gear 1 51 to rotate, and further drives the meshing bevel gear 2 52 to rotate, so that the rotating rod 53 drives the fan blade 2 54 to rotate, so that the hot air generated by the heater 6 can be evenly blown to the surface of the mother liquid to concentrate it.

[0038] As Figure 4 shown, the barrier net 55 is U-shaped, and the second fan blade 54 is located inside the barrier net 55.

[0039] As can be seen from the above, the second fan blade 54 is located inside the barrier net 55, and the barrier net 55 can protect the fan blade to prevent the mother liquor from adhering to the surface of the second fan blade 54 and affecting the crystallization efficiency.

[0040] After heating the mother liquor to a certain degree, it can be left standing and waiting for natural cooling. At the same time, the crystallization assembly 5 can be used to assist the concentrated mother liquor in cooling, and thus crystallization can be formed. While cooling, the purification assembly 9 is driven to purify the harmful gases generated during the crystallization process. After crystallization is completed, the discharge valve 8 is opened to discharge the mother liquor that has completed crystallization.

[0041] The working principle of the present utility model is as follows: During use, first, the feed valve 10 is opened, and feeding is carried out through the feed hopper 4. After the mother liquor is poured in, the heater 6 is started to heat and concentrate the mother liquor. Then, through the crystallization assembly 5, the efficiency of concentrating the mother liquor can be assisted. At the same time, the harmful gases generated during the heating process enter the box body 91 through the connecting pipe 96 and are purified by the purification assembly 9. The purified gas is discharged from the exhaust pipe 72, and through the auxiliary assembly 7, the discharge of the gas can be assisted to prevent directly discharging the harmful gas into the air and polluting the air. After heating to a certain degree and the concentration is completed, it can be left standing and waiting for natural cooling. At the same time, the crystallization assembly 5 can be used to assist the concentrated mother liquor in cooling, and thus crystallization can be formed. While cooling, the purification assembly 9 is driven to purify the harmful gases generated during the crystallization process. After crystallization is completed, the discharge valve 8 is opened to discharge the mother liquor that has completed crystallization.

[0042] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments.
