Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to a polyethylene glycol dimethyl ether solvent production device. Background Technology

[0002] A reaction vessel is a piece of equipment used for chemical reactions, widely applied in industries such as chemical, pharmaceutical, food, and materials. It is primarily used to complete chemical reactions under specific temperature, pressure, and stirring conditions. Polyethylene glycol dimethyl ether (PEG) is an important organic solvent with good chemical and thermal stability, widely used in gas purification, pharmaceuticals, cosmetics, and industrial fields. In the production process of PEG, the reaction vessel is one of the key pieces of equipment. Production typically employs a one-step process, where polyethylene glycol, sodium hydroxide, and an organic reaction medium are added to the reaction vessel in a specific molar ratio, followed by the introduction of halomethane or dimethyl sulfate, and the reaction is carried out at a temperature of 30–90°C.

[0003] Currently, after use, the reactors used for producing polyethylene glycol dimethyl ether solvent require internal cleaning. However, internal water rinsing is insufficient to remove the raw materials from the stirring blades, often necessitating opening the reactor for cleaning. The reactor lid is typically secured with bolts, making opening it cumbersome. Inadequate cleaning of the reactor can affect subsequent polyethylene glycol dimethyl ether solvent production. Therefore, a polyethylene glycol dimethyl ether solvent production device is proposed to address these issues. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a polyethylene glycol dimethyl ether solvent production device in response to the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a polyethylene glycol dimethyl ether solvent production device, including a kettle body, a kettle cover provided on the kettle body, and a stirring mechanism provided on the kettle body;

[0006] The stirring mechanism includes a fixed ring frame and a base plate. A support plate is fixedly connected to the fixed ring frame. A first hydraulic cylinder is hinged to the support plate via a pin. The other end of the first hydraulic cylinder is hinged to the vessel lid. A second hydraulic cylinder is fixedly connected to the base plate. A lifting plate is fixedly connected to the telescopic end of the second hydraulic cylinder. A motor is fixedly connected to the lifting plate. A rotating shaft is fixedly connected to the output end of the motor. A hinge seat is fixedly connected to the vessel lid.

[0007] Preferably, a connecting seat is fixedly connected to the vessel body, the hinge seat is hinged to the connecting seat by a pin, and the fixing ring is fixedly connected to the outer wall of the vessel body. The connection seat and the hinge seat facilitate the opening and closing of the vessel lid.

[0008] Preferably, a stirring blade is fixedly connected to the rotating shaft, a feed inlet is provided on the lid, and a discharge outlet is provided at the bottom of the vessel. The rotation of the rotating shaft allows the stirring blade to stir the raw materials.

[0009] Preferably, there are two second hydraulic cylinders, which are fixedly connected to the left and right ends of the upper surface of the base plate, respectively. The position and height of the motor can be adjusted by activating the second hydraulic cylinders.

[0010] Preferably, an electric heating coil is fixedly connected to the outer wall of the vessel body, and an insulation sleeve is fixedly connected to the outer wall of the vessel body. The vessel body can be heated by the electric heating coil.

[0011] Preferably, the bottom of the vessel lid is provided with a scraping mechanism, which includes a fixed seat fixedly connected to the bottom of the vessel lid. A fixed ring is fixedly connected inside the fixed seat, and a rubber scraper is fixedly connected to the inner wall of the fixed ring. The rotating shaft passes through the interior of the rubber scraper. The material scraping mechanism can scrape off the raw material on the rotating shaft.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This polyethylene glycol dimethyl ether solvent production device uses a motor to drive a rotating shaft, which in turn stirs the raw materials with agitator blades. Activating a second hydraulic cylinder adjusts the height of the motor, thereby adjusting the height of the stirring blades inside the reactor body and improving the stirring efficiency. When the reactor is empty and cleaning is required, activating the second hydraulic cylinder raises the stirring blades to their highest position. Then, activating the first hydraulic cylinder pushes the reactor cover to rotate around the connecting seat, opening the reactor and facilitating cleaning by personnel, thus improving cleaning efficiency.

[0014] 2. In this polyethylene glycol dimethyl ether solvent production device, as the rotating shaft rises, a rubber scraper removes the raw material on the rotating shaft, preventing the shaft from carrying the raw material out of the reactor body, thus further improving the practicality of the production device.

[0027] An electric heating coil 5 is fixedly connected to the outer wall of the vessel body 1, and an insulation sleeve 6 is fixedly connected to the outer wall of the vessel body 1. The vessel body 1 can be heated by the electric heating coil 5.

[0028] Working principle: The motor 208 drives the rotating shaft 209 to rotate, causing the stirring blades 210 to stir the raw materials. The second hydraulic cylinder 206 can be activated to adjust the position and height of the motor 208, thereby adjusting the position and height of the stirring blades 210 inside the reactor body 1, thus improving the stirring efficiency of the raw materials. When the reactor body 1 is discharged and cleaning is required, the second hydraulic cylinder 206 is activated to raise the stirring blades 210 to the highest position. Then, the first hydraulic cylinder 203 is activated to push the reactor cover 4 to flip around the connecting seat 211, opening the reactor and facilitating cleaning by the staff, thus improving cleaning efficiency.
