Description

Technical Field

[0001] This utility model relates to the field of methyl pyruvate production technology, and more specifically, to a production and synthesis apparatus for methyl pyruvate. Background Technology

[0002] Methyl pyruvate is an important organic synthesis intermediate, mainly used in pharmaceuticals, pesticides, and chemical research. In the synthesis of methyl pyruvate, raw materials are added to a reaction vessel and heated to allow them to react inside. The resulting product is then obtained through distillation or other separation techniques. After the reaction is complete, the product is discharged from the vessel, but some material adheres to the inner wall, resulting in significant residue that affects further processing and hinders normal operation. This necessitates cleaning the vessel's inner wall, increasing labor costs. Therefore, we propose a methyl pyruvate synthesis apparatus. Summary of the Invention

[0003] The purpose of this invention is to provide a production and synthesis apparatus for methyl pyruvate, in order to solve the problem mentioned in the background art where residual material inside the reactor affects the further processing of subsequent materials.

[0004] To address the aforementioned problems, the present invention aims to provide a production and synthesis apparatus for methyl pyruvate, comprising a vessel body, a top cover fixedly connected to the top of the vessel body by bolts, and a mixing mechanism inside the vessel body. The mixing mechanism includes a stirring component, a lifting component, and a driving component. The stirring component is located inside the vessel body, the lifting component is located on the upper side of the top cover, and the driving component connects the stirring component and the lifting component together. The lifting component moves the stirring component upward to separate it from the inner wall of the vessel body, and the driving component rotates the stirring component to stir and mix the raw materials inside the vessel body. The lifting component moves the stirring component downward to make it fit against the inner wall of the vessel body, and the driving component rotates the stirring component in the opposite direction to scrape off the material adhering to the inner wall of the vessel body.

[0005] As a further improvement to this technical solution, the stirring assembly includes a stirring shaft rotatably connected to the top cover, the stirring shaft sliding up and down on the top cover, and a plurality of stirring rods symmetrically fixedly connected to the stirring shaft along the axial direction of the stirring shaft, with an inclined plate fixedly connected to the end of the stirring rod away from the stirring shaft.

[0006] As a further improvement to this technical solution, two centrally symmetrical arc-shaped plates are fixedly connected to the lower end of the stirring shaft. The arc-shaped plates are inclined. When the stirring shaft rotates, it drives the arc-shaped plates to rotate and stir the raw materials. The rotating arc-shaped plates drive the raw materials at the bottom of the vessel to move upward.

[0007] As a further improvement to this technical solution, the lifting assembly includes two electric telescopic rods symmetrically and fixedly connected to the upper side of the top cover. The piston rod of the electric telescopic rod is fixedly connected to a mounting frame. During the extension and retraction process, the piston rod of the electric telescopic rod drives the mounting frame to move upward or downward.

[0008] As a further improvement to this technical solution, the drive assembly includes a drive motor fixedly connected between two mounting brackets. The mounting brackets drive the drive motor to move during the movement process. The output shaft of the drive motor is coaxially and fixedly connected to the upper end of the stirring shaft through a coupling. The rotating output shaft of the drive motor drives the stirring shaft to rotate.

[0009] As a further improvement to this technical solution, two limiting rods are fixedly connected to the upper end of the top cover. A limiting groove is opened on the side of the telescopic mounting bracket away from the drive motor. The limiting rods slide in contact with the inner wall of the limiting groove. Under the restriction of the limiting rods, the mounting bracket moves along the axial direction of the limiting rods.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The methyl pyruvate production synthesis device uses a mixing mechanism to stir and mix the raw materials inside the reactor, causing them to react and produce the desired material, which is then discharged. During the material discharge process inside the reactor, the lifting component drives the stirring component to move downwards, making the stirring component fit tightly against the inner wall of the reactor. At this time, the drive component drives the stirring component to rotate. During the rotation, the stirring component scrapes off the material adhering to the inner wall of the reactor, allowing the material to flow downwards along the inner wall of the reactor and be discharged through the discharge pipe, thereby reducing the residue of material inside the reactor and facilitating subsequent cleaning and use of the reactor by the staff.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0014] Please see Figure 1 - Figure 4 As shown, the purpose of this embodiment is to provide a production and synthesis apparatus for methyl pyruvate, including a vessel body 1. The diameter of the upper side of the inner wall of the vessel body 1 is larger than the diameter of the lower side, so that the inner wall of the vessel body 1 is inclined inward from top to bottom. A water storage cavity is opened in the side wall of the vessel body 1. A water inlet pipe is fixedly connected to the side wall of the vessel body 1 near the top. A water outlet pipe and a material outlet pipe are fixedly connected to the bottom of the vessel body 1. The water inlet pipe and the water outlet pipe are connected to the water storage cavity. Hot water is injected into the interior of the water storage cavity through the water inlet pipe, so that the hot water in the water storage cavity heats the raw materials inside the vessel body 1, thereby improving the reaction efficiency between the raw materials. The material outlet pipe is connected to the interior of the vessel body 1, and the material inside the vessel body 1 is discharged through the material outlet pipe, which facilitates the discharge of the material. In subsequent processing, a valve is fixedly connected inside the discharge pipe, which controls the opening and closing of the discharge pipe. A top cover 11 is fixedly connected to the top of the vessel body 1 by bolts, which seals the top of the vessel body 1. A feed pipe is fixedly connected to the top of the top cover 11. During use, a solenoid valve can be installed on the feed pipe. The solenoid valve is connected to the external raw material conveying equipment through a pipeline. The raw material enters the feed pipe through the pipeline and the solenoid valve. The solenoid valve controls the opening and closing to control the movement of the raw material. When the solenoid valve is open, the raw material enters the interior of the vessel body 1 through the feed pipe. An end cap is fixedly connected to the upper end of the feed pipe, which seals the feed pipe to prevent the raw material from splashing out of the interior of the vessel body 1, thus reducing the waste of raw material. The vessel body 1 is equipped with a mixing mechanism 2, which includes a stirring component, a lifting component, and a driving component. The stirring component is located inside the vessel body 1, and the lifting component is located on the top cover 11. The driving component connects the stirring component and the lifting component together. The shape of the edge of the stirring component matches the shape of the inner wall of the vessel body 1. When it is necessary to stir the raw materials in the vessel body 1, the lifting component drives the stirring component to move upward. At this time, the diameter of the stirring component is smaller than the diameter at the same plane of the vessel body 1, so that there is a gap between the stirring component and the inner wall of the vessel body 1. The driving component drives the stirring component to rotate so that it stirs and mixes the raw materials inside the vessel body 1. After the raw materials in the vessel body 1 react, the material is discharged from the inside of the vessel body 1. During this process, the lifting component drives the stirring component to move downward so that it fits against the inner wall of the vessel body 1. The driving component drives the stirring component to rotate in the opposite direction so that it scrapes off the material attached to the inner wall of the vessel body 1, so that the material moves downward along the inner wall of the vessel body 1, making it easier for the material to be discharged from the inside of the vessel body 1 and reducing the residue of the material inside the vessel body 1.

[0015] refer to Figure 2 - Figure 5 The stirring assembly includes a stirring shaft 21 rotatably connected to the top cover 11. The stirring shaft 21 slides up and down on the top cover 11. Several stirring rods 211 are symmetrically fixedly connected to the stirring shaft 21 along its axis. An inclined plate 212 is fixedly connected to the end of the stirring rod 211 away from the stirring shaft 21. Two centrally symmetrical arc plates 213 are fixedly connected to the lower end of the stirring shaft 21. The arc plates 213 are inclined. When the stirring shaft 21 drives the arc plates 213 to rotate and stir the raw materials, the rotating arc plates 213 drive the raw materials at the bottom of the vessel body 1 to move upward. During the raw material mixing process, a gap is left between the inclined plate 212 and the arc plate 213 and the inner wall of the vessel 1. When the stirring shaft 21 rotates, it drives the stirring rod 211, the inclined plate 212 and the arc plate 213 to rotate and mix the raw materials. At the same time, the rotating inclined plate 212 and the arc plate 213 drive the raw materials to move from bottom to top, expanding the mixing range of the stirring components on the raw materials inside the vessel 1 and improving the mixing effect of the stirring components on the raw materials. When the raw materials are discharged after the reaction is completed, the inclined plate 212 and the arc plate 213 are in contact with the inner wall of the vessel 1. When the stirring shaft 21 rotates in the opposite direction, it moves the stirring rod 211, the inclined plate 212 and the arc plate 213 to rotate. The reverse rotating inclined plate 212 and the arc plate 213 scrape off the material attached to the inner wall of the vessel 1, so that the material moves down along the inner wall of the vessel 1 and is discharged, reducing the residue of material inside the vessel 1 and facilitating the subsequent use and cleaning of the vessel 1.

[0016] refer to Figure 2 - Figure 5The lifting assembly includes two electric telescopic rods 22 symmetrically fixedly connected to the upper side of the top cover 11. The piston rods of the electric telescopic rods 22 are fixedly connected to the mounting brackets 221. During the extension and retraction process, the piston rods of the electric telescopic rods 22 drive the mounting brackets 221 to move upward or downward. The drive assembly is located between the two mounting brackets 221. The moving mounting brackets 221 drive the stirring assembly to move through the drive assembly. When it is necessary to stir the raw materials inside the vessel 1, the piston rod of the electric telescopic rod 22 retracts and drives the stirring assembly to move upward through the mounting brackets 221, so that the stirring assembly separates from the inner wall of the vessel 1, avoiding damage caused by long-term friction between the stirring assembly and the inner wall of the vessel 1 during rotation. When it is necessary to discharge the material inside the vessel 1, the piston rod of the electric telescopic rod 22 extends and drives the stirring assembly to move downward, so that the stirring assembly fits against the inner wall of the vessel 1. During the rotation process, the stirring assembly scrapes off and discharges the material attached to the inner wall of the vessel 1.

[0017] refer to Figure 2 - Figure 4 The drive assembly includes a drive motor 23 fixedly connected between two mounting brackets 221. The drive motor 23 is a motor whose output shaft can rotate in both directions. The mounting brackets 221 drive the drive motor 23 to move during the movement. The output shaft of the drive motor 23 is coaxially and fixedly connected to the upper end of the stirring shaft 21 through a coupling. The rotating output shaft of the drive motor 23 drives the stirring shaft 21 to rotate. Two limiting rods are fixedly connected to the upper end of the top cover 11. A limiting groove is opened on the side of the telescopic mounting bracket 221 away from the drive motor 23. The limiting rod slides in contact with the inner wall of the limiting groove. Under the restriction of the limiting rod, the position of the mounting bracket 221 and the drive motor 23 is restricted, which increases the stability of the drive motor 23 during use. At the same time, the movement path of the mounting bracket 221 is restricted, so that the moving mounting bracket 221 moves along the axial direction of the limiting rod.

[0018] When using this device: In the production process of methyl pyruvate, the end cap is opened and the raw material is poured into the interior of the reactor body 1 through the feed pipe. Then, the staff seals the feed pipe through the end cap. At this time, there is a gap between the inclined plate 212 and the arc plate 213 and the inner wall of the reactor body 1. The output shaft of the drive motor 23 rotates and drives the stirring shaft 21 to rotate, which in turn drives the stirring rod 211, the inclined plate 212 and the arc plate 213 to rotate and stir and mix the raw material. After the raw materials inside the vessel 1 have reacted, the material inside the vessel 1 is discharged through the discharge pipe. During this process, the piston rod of the electric telescopic rod 22 extends and drives the stirring shaft 21 to move downward. The moving stirring shaft 21 drives the inclined plate 212 and the arc plate 213 to move so that they fit against the inner wall of the vessel 1. At this time, the output shaft of the drive motor 23 rotates in the opposite direction and drives the stirring shaft 21 to rotate. The rotating stirring shaft 21 drives the inclined plate 212 and the arc plate 213 to rotate so that they scrape off the material attached to the inner wall of the vessel 1 and discharge it through the discharge pipe, thereby reducing the residue of material inside the vessel 1.
