[0002] With the development of society and technology, equipment in various fields has been greatly improved. Various equipment will be used in the production and manufacturing process of chemical raw materials. Some of the raw materials are mainly produced by organic synthesis. After the organic synthesis product is produced, it is often mixed with other impurities. At this time, it is necessary to use a purification device to purify the raw materials of organic synthesis and remove various impurities inside, which greatly improves work efficiency and product quality.
[0003] After searching, the publication number CN209392783U, application date 2018.12.30 discloses a multi-stage purification device for chemical synthesis, including a base, a condensation sleeve, a collecting bottle and an external pipe, the left and right sides of the top of the base are fixedly installed with side wall panels, the top of the side wall panels is fixedly connected to a top plate, and the bottom of the top plate is fixedly connected to a filter box located between the two side wall panels. The multi-stage purification device for chemical synthesis can use a distillation bottle to distill and separate the extracted raw materials with extraction reagents and the extraction reagents into two collecting bottles for separate packaging, thereby achieving the effect of purifying the raw materials.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1
[0032] See also Figures 1 to 4 The utility model is a purification device for organic synthesis, comprising a filter box 1 and a side frame 101 fixedly arranged at the center of the outer wall of one side thereof, the bottom center of the filter box 1 is connected to the top side of an extraction box 104 through a delivery pipe 103, a shell 105 is arranged on the lower side of the extraction box 104, a distillation box 106 is installed at the bottom end of the inner part of the shell 105, a heating pipe 107 is sleeved on the outer side of the outer wall of the distillation box 106, an adjustment component 2 is arranged inside the filter box 1 and the side frame 101; the adjustment component 2 comprises a right side plate 201 and a motor 203 installed at the top of the outer wall thereof, the output shaft of the motor 203 passes through the bearing on the outer wall of the right side plate 201 and is connected to the upper threaded rod 2031 through a coupling;
[0033] Specifically, a feed pipe 102 is arranged above the outer wall of the other side of the filter box 1, a liquid pumping mechanism 1041 is arranged on one side of the outer wall of the extraction box 104, and the other end of the liquid pumping mechanism 1041 is arranged on one side of the top of the distillation box 106, and the bottom side of the extraction box 104 is connected to the other side of the top of the distillation box 106 through the delivery pipe 103, a distillation pipe 1061 is arranged above the outer wall of one side of the distillation box 106, and a tail pipe 1062 is arranged at the bottom center of the distillation box 106, and the other end of the upper threaded rod 2031 passes through the threaded holes on the center position of the outer wall of one side of the active gear plate 2032 and the end surface of one side of the upper slider 204 and the inner wall of the left side plate 202 in sequence. A driven gear disc 2033 is arranged directly below the driving gear disc 2032, a lower threaded rod 2034 is installed at the center of the inner wall of the driven gear disc 2033, one end of the lower threaded rod 2034 passes through the center of one side end surface of the driven gear disc 2033 and is connected to the bearing on the inner wall of the right side plate 201, the other end of the lower threaded rod 2034 passes through the threaded hole at the center of one side end surface of the lower slider 205 and is connected to the bearing on the inner wall of the left side plate 202, the inner side walls of the upper slider 204 and the lower slider 205 are respectively installed with an upper mounting frame 206 and a lower mounting frame 207, and filters 208 are placed inside the upper mounting frame 206 and the lower mounting frame 207.
[0034] Furthermore, the housing 105 can keep the heat generated by the heating tube 107 warm and insulate it, thereby reducing heat loss. The pumping mechanism 1041 is a prior art, so it will not be described in detail here. The operation of the motor 203 drives the upper threaded rod 2031 and the active toothed disc 2032 on its outer wall to rotate. The gear on the outer wall of the active toothed disc 2032 is meshed and connected with the gear on the outer wall of the driven toothed disc 2033, thereby playing a transmission role. When the active toothed disc 2032 and the driven toothed disc 2033 rotate, the rotation directions are opposite, thereby driving the lower threaded rod 2034 to rotate, wherein the external threads on the outer walls of the upper threaded rod 2031 and the lower threaded rod 2034 are respectively meshed and connected with the internal threads in the walls of the threaded holes on the end faces of the upper slider 204 and the lower slider 205. Therefore, when the upper threaded rod 2031 and the lower threaded rod 2034 rotate, the upper slider 204 and the lower slider 205 will be driven to move toward each other, thereby driving the upper mounting frame 206 and the lower mounting frame 207 to move.
[0035] The operation process of this embodiment is as follows: raw materials are added into the filter box 1 through the feed pipe 102, and the solid impurities inside are filtered out, and then the raw materials are fed into the extraction box 104 through the delivery pipe 103. After extraction, the required solution is fed into the distillation box 106 through the delivery pipe 103 or the liquid extraction mechanism 1041 according to the stratification situation, and then the heating pipe 107 is started, and the solution inside the distillation box 106 is distilled. Finally, the raw materials and the solvent are purified through the distillation pipe 1061 and the tail pipe 1062. After the filter screen 208 inside the upper mounting frame 206 has been used for a period of time, the motor 203 is started at this time, and the output shaft of the motor 203 rotates to drive the upper threaded rod 2031 to rotate through the coupling, and the rotation of the upper threaded rod 2031 will drive the active toothed disc 2032 on its outer wall to rotate. Since the gear on the outer wall of the active toothed disc 2032 and the outer wall of the driven toothed disc 2033 are The gears on the upper and lower slide blocks 204 and 205 are meshed and connected, so when the active toothed disc 2032 rotates, it will drive the driven toothed disc 2033 to rotate, and the two rotate in opposite directions. The rotation of the driven toothed disc 2033 will drive the lower threaded rod 2034 on its inner wall to rotate. At the same time, the external threads on the outer walls of the upper threaded rod 2031 and the lower threaded rod 2034 are respectively meshed and connected with the threaded holes on the end faces of the upper slider 204 and the lower slider 205. Therefore, when the upper threaded rod 2031 and the lower threaded rod 2034 rotate, the upper slider 204 and the lower slider 205 are driven to move in opposite directions, thereby adjusting the relative position of the upper mounting frame 206 and the lower mounting frame 207, so that the lower mounting frame 207 is placed inside the filter box 1, and the filter screen 208 inside the lower mounting frame 207 is used to continuously filter the raw materials. At the same time, the filter screen 208 in the upper mounting frame 206 can be taken out for cleaning and replacement without affecting the filtering efficiency, and the working efficiency is high. Specific embodiment 2
[0037] See also Figure 2 , 5 On the basis of the first specific embodiment, what is different from the first embodiment is that: a recovery component 3 is provided, the recovery component 3 includes a displacement box 301 and a fan 302 installed on one side of the upper surface thereof, a displacement pipe 304 is arranged inside the displacement box 301, and the air outlet end of the fan 302 is connected to the top of the displacement pipe 304 through a pipe joint, which solves the problem that the existing heating plate is exposed to the environment, and the residual heat inside the distillation bottle after purification is completed will cause heat waste and lead to low energy utilization.
[0038] Specifically, the air inlet end of the fan 302 is connected to the connecting pipe 3021 through a pipe joint, the other end of the connecting pipe 3021 is connected to the exhaust pipe 303 through a pipe joint, and the other end of the exhaust pipe 303 passes through the outer wall of the outer shell 105 and is arranged on the outer wall of the distillation box 106.
[0039] Furthermore, the pipe joint plays the role of connecting the pipelines. The fan 302 operates to extract the residual heat in the distillation box 106 through the exhaust pipe 303, and then uses the displacement pipe 304 to make the internal air heat displace with the cold water in the displacement box 301 to reduce heat loss.
[0040] The operation process of this embodiment is as follows: after the purification of the raw materials is completed, a part of the heat will remain inside the distillation box 106. At this time, the fan 302 is started, and the fan 302 operates to extract the residual heat in the distillation box 106 through the exhaust pipe 303, and then enters the displacement pipe 304 through the connecting pipe 3021, and heat is exchanged with the cold water inside the displacement box 301 through the displacement pipe 304, so that the residual heat can be recovered and utilized, thereby reducing heat waste and improving energy utilization.
