Technical Field
[0001] The utility model relates to the technical field of ethylene glycol reaction stirrers, in particular to an improved structure of an ethylene glycol reaction stirrer. Background Art
[0002] Ethylene glycol, also known as "glycol" and "ethylene glycol", abbreviated as EG, has a chemical formula of (CH2OH)2 and is the simplest diol. Ethylene glycol is a colorless, odorless, sweet-tasting liquid that is toxic to animals. The lethal dose for humans is about 1.6g / kg. Ethylene glycol is miscible with water and acetone, but has a lower solubility in ethers. It is used as a solvent, antifreeze, and a raw material for synthetic polyester. Ethylene glycol reaction agitators are used for stirring and mixing in the ethylene glycol production process. Their main function is to fully mix the ethylene glycol solution with other reactants through the stirring device to increase the reaction rate and effect. The design and selection of ethylene glycol reaction agitators need to consider many factors, including container size, medium characteristics, operating conditions, etc., to ensure that the stirring effect meets the process requirements. In actual applications, ethanol reaction agitators are widely used in chemical, pharmaceutical and other fields and are one of the important equipment in the ethylene glycol production process.
[0003] Existing ethylene glycol reaction agitators are generally designed with an internal stirring paddle, which is used to stir and mix the materials inside the container. However, the internal agitator may not be able to achieve all-round mixing of the materials, resulting in insufficient mixing of materials in certain areas, affecting product quality and reaction efficiency. In certain corners or edges inside the container, the materials may be difficult to be effectively stirred, forming dead corners, which not only reduces the effective reaction volume, but also may cause product inhomogeneity. Higher energy input may be required to maintain the required stirring effect. In addition, due to the complexity of the internal structure, cleaning and maintenance work become more difficult. In view of this, we propose an improved structure of ethylene glycol reaction agitator. Utility Model Content

[0020] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] Ethylene glycol, also known as "glycol" and "ethylene glycol", abbreviated as EG, has the chemical formula (CH2OH)2. It is the simplest diol. Ethylene glycol is a colorless, odorless, sweet liquid that is toxic to animals. The lethal dose for humans is about 1.6g / kg. Ethylene glycol is miscible with water and acetone, but has a lower solubility in ethers. It is used as a solvent, antifreeze, and a raw material for synthetic polyester. The ethylene glycol reaction agitator is used for stirring and mixing in the ethylene glycol production process. Its main function is to fully mix the ethylene glycol solution with other reactants through the stirring device to increase the reaction rate and effect. The design and selection of the ethylene glycol reaction agitator need to consider many factors, including container size, medium characteristics, operating conditions, etc., to ensure that the stirring effect meets the process requirements. In actual applications, ethanol reaction agitators are widely used in chemical, pharmaceutical and other fields, and are one of the important equipment in the ethylene glycol production process.
[0022] See also Figure 1-Figure 3As shown, this embodiment provides an improved structure of an ethylene glycol reaction agitator, including a reaction vessel 100 and a support base 200. Considering that the existing ethylene glycol reaction agitator is generally designed to have an internal stirring paddle, the stirring paddle is used to stir and mix the material inside the container, but the internal agitator may not be able to achieve all-round mixing of the material, resulting in insufficient mixing of the material in some areas, affecting the product quality and reaction efficiency. In some corners or edges inside the container, the material may be difficult to be effectively stirred, forming dead corners, which not only reduces the effective reaction volume, but also may cause the product to be uneven. A higher energy input may be required to maintain the required stirring effect. Moreover, due to the complexity of the internal structure, cleaning and maintenance work become more difficult. Therefore, the specific details are as follows: a drive assembly 300 is installed on the side wall of the support base 200, and the reaction vessel 100 and the support base 200 are rotatably connected, wherein:
[0023] The top of the reaction container 100 is threadedly engaged with a sealing plate 102 , and the lower surface of the sealing plate 102 is symmetrically engaged with a connecting rod 1023 , and the bottom end of the connecting rod 1023 is connected to a grid plate 1024 .
[0024] The improvement of this embodiment is that:
[0025] The driving assembly 300 is used to control the reaction vessel 100 to rotate 360 degrees. Through its continuous rotational motion, the dead corners that may exist in the reaction vessel 100 can be effectively eliminated, so that all materials can participate in the reaction, and the materials in the entire reaction vessel 100 can be mixed more evenly, ensuring that all materials can be fully stirred and reacted; a grid plate 1024 is installed inside the reaction vessel 100, which can realize real-time filtration and separation of products or by-products while the reaction is in progress, which not only improves production efficiency, but also can further avoid the occurrence of condensation during the reaction process.
[0026] Specifically, the outer wall of the reaction vessel 100 is provided with a mounting bracket 101, and the two opposite side walls of the mounting bracket 101 are fixedly connected with a rotating shaft 1010, and the two ends of the upper surface of the support base 200 are symmetrically connected with a fixing seat 201, wherein: the rotating shaft 1010 passes through the fixing seat 201 and rotates with it.
[0027] In order to prevent the sealing plate 102 from slightly separating from the reaction vessel 100 during the rotation of the reaction vessel 100, thereby causing leakage of reactants, a fixing plate 1020 is provided above the sealing plate 102. Locking members 1021 are provided between the ends of the surface of the fixing plate 1020 and the ends of the upper surface of the mounting bracket 101. The fixing plate 1020 and the mounting bracket 101 are bolted together by the locking members 1021.
[0028] By arranging a fixing plate 1020 above the sealing plate 102, the size of the fixing plate 1020 can completely cover and fix the sealing plate 102. The main function of the fixing plate 1020 is to provide a stable support surface to ensure that the sealing plate 102 will not be displaced during the rotation process; the fixing plate 1020 is connected to the mounting bracket 101 by bolts. This connection method is simple and reliable, and can provide sufficient strength and stability to ensure that the fixing plate 1020 will not be displaced during the rotation process. At the same time, it is convenient to open the sealing plate 102 later. This structure not only improves the safety and reliability of the reaction vessel 100, but also helps to extend the service life of the equipment and reduce maintenance costs.
[0029] In order to realize the automatic rotation of the reaction vessel 100, a rotating shaft 202 is rotatably connected to the side wall of the support base 200, and a driven wheel 1011 is provided at the end of one of the rotating shafts 1010. The driving component 300 includes a driving motor 301 and a driving wheel 302, and the driving wheel 302 is sleeved on the outer wall of the rotating shaft 202. The driving component 300 also includes a driving belt 303, and two groups of driving belts 303 are provided, wherein: they are respectively provided on the outer wall of the driven wheel 1011 and the outer wall of the rotating shaft 202, and on the outer wall of the output end of the driving motor 301 and the outer wall of the driving wheel 302; by starting the driving motor 301 to rotate the output shaft, the two groups of driving belts 303 are used to rotate the driving wheel 302 to drive the rotating shaft 202 to rotate, thereby driving the driven wheel 1011 to rotate, and then driving the rotating shaft 1010 to rotate, thereby driving the reaction vessel 100 to rotate 360 degrees, so that the internal materials are fully mixed.
[0030] In addition, a feed pipe 103 is installed at the top of the outer wall of the reaction container 100, and a discharge pipe 104 is installed at the bottom. Valves are installed on the outer walls of the feed pipe 103 and the discharge pipe 104.
[0031] By installing the feed pipe 103 and the discharge pipe 104 at the top and bottom of the container respectively, the user can conveniently add and discharge materials. At the same time, the external valve is also convenient for the operator to control. By controlling the inlet and outlet of materials by the valve, safety accidents such as leakage or explosion caused by improper operation during the reaction process can be avoided. Since the feed pipe 103, the discharge pipe 104 and the valve are all located outside the container, they are easier to inspect and maintain. Once a fault or damage is found, they can be replaced or repaired in time.
[0032] When the improved structure of the ethylene glycol reaction agitator of the present invention is used, the staff will feed ethylene glycol and other materials into the reaction vessel 100 through the feed pipe 103, and then start the drive motor 301 to rotate the output shaft. The two sets of drive belts 303 are used to rotate the driving wheel 302 to drive the rotating shaft 202 to rotate, thereby driving the driven wheel 1011 to rotate, and then driving the rotating shaft 1010 to rotate, thereby driving the reaction vessel 100 to rotate 360 degrees to fully mix the internal materials. Among them, the grid plate 1024 installed inside the reaction vessel 100 can achieve real-time filtering and separation of products or by-products while the reaction is in progress, which can further avoid the occurrence of coagulation during the reaction process. Finally, the reaction product is discharged through the discharge pipe 104. In addition, if you want to clean the inside of the reaction vessel 100, you only need to remove the bolts connecting the fixed plate 1020 and the mounting bracket 101, remove the fixed plate 1020, and then rotate the sealing plate 102 to remove it from the reaction vessel 100.
