Description

Technical Field

[0001] This utility model belongs to the technical field of water-reducing agent processing equipment, and in particular relates to a reaction vessel for water-reducing agent production. Background Technology

[0002] Water-reducing agents are concrete admixtures that reduce the amount of water used in mixing while maintaining a relatively constant slump. Most are anionic surfactants, including lignin sulfonates, naphthalene sulfonates, and formaldehyde polymers. When added to concrete mixes, they disperse cement particles, improve workability, reduce water consumption per unit area, improve the fluidity of the concrete mix, or reduce the amount of cement used per unit area. Water-reducing agents are available in liquid and powder forms.

[0003] Water-reducing agents come in two forms: aqueous solutions and powders. Aqueous solutions typically have a solids content of 20%, 40% (also known as mother liquor), or 60%, while powders generally have a solids content of 98%. The production of water-reducing agents requires a reaction vessel to stir and mix various raw materials. A reaction vessel is a device used for chemical reactions, commonly found in laboratories and industrial production. It can conduct chemical reactions under high pressure, high temperature, inert atmosphere, or harmful gas conditions, and is commonly used for synthesizing organic compounds, preparing pharmaceuticals, and producing chemical products.

[0004] There are several shortcomings in using existing water-reducing agent reactors for preparation: First, a sealing cap is installed at the top of the reactor, but the cap has a certain weight, so it needs to be lifted down manually when removing it, which is cumbersome, time-consuming, and labor-intensive. Second, existing water-reducing agent reactors usually use a simple stirring rod to stir the raw materials, which not only has low processing efficiency, but also makes the raw materials easily adhere to the inner wall and bottom of the reactor shell, resulting in insufficient mixing. This not only affects the overall production quality but also the subsequent production progress. Therefore, it is urgent to design a reactor for water-reducing agent production to solve the above problems. Utility Model Content

[0005] This invention provides a reactor for producing water-reducing agents with a reasonable structural design to solve the technical problems existing in the prior art. This invention can enhance the mixing effect of raw materials near the inner wall of the reactor, improve the overall mixing efficiency and production quality, and utilize a lifting assembly to move the sealing cover up and down, eliminating the need for manual handling of the sealing cover and simplifying the operation process.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A reaction vessel for producing water-reducing agent includes a mounting bracket, a lower cylinder structure fixedly connected to the mounting bracket, a reaction sealing cover fastened to the opening of the lower cylinder structure, and several locking components provided between the lower cylinder structure and the reaction sealing cover; a stirring assembly three, a stirring assembly one, and a stirring assembly two are installed on the reaction sealing cover; a lifting assembly is also included on the mounting bracket for driving the reaction sealing cover to move up and down; a feed inlet, a liquid inlet, and a thermocouple are provided on the reaction sealing cover; the stirring assembly three includes a stirring motor three installed on the reaction sealing cover, and a [missing information - likely a component or component] is installed on the output shaft of the stirring motor three. A stirring shaft three, located at the center of the lower cylinder structure and arranged longitudinally, is equipped with a stirring frame structure. Several wall scrapers that contact the inner wall of the lower cylinder structure and several bottom scrapers that contact the bottom surface of the inner cavity are mounted on the stirring frame structure. Stirring assembly two and stirring assembly one are located on opposite sides of stirring shaft three. A guide rail mounting component is fixed to a mounting bracket. The lifting assembly includes a longitudinally arranged lifting guide rail fixed to the guide rail mounting component and a lifting drive component mounted on the mounting bracket. A movable connecting mechanism connected to the reaction sealing cover is mounted on the moving end of the lifting drive component. The movable connecting mechanism is slidably connected to the lifting guide rail via a slider.

[0007] The advantages and positive effects of this utility model are as follows: This utility model provides a reaction vessel for the production of water-reducing agents. The three-part stirring assembly can stir the materials near the inner wall and bottom of the reaction vessel and scrape the walls during the stirring process, preventing materials from adhering to the inner wall of the reaction vessel for extended periods and affecting subsequent cleaning operations. The first and second stirring assemblies further ensure thorough stirring of the materials in the reaction vessel, resulting in complete mixing of the raw materials and improving overall production quality and work efficiency. The lifting assembly allows the reaction sealing cover to be moved up and down using a lifting drive when cleaning and maintenance are required, eliminating the need for personnel to move the reaction sealing cover and simplifying the operation. The movable connection mechanism in the lifting assembly enables the movable connection between the reaction sealing cover and the lifting assembly, ensuring that after the reaction sealing cover is raised to the point where each stirring assembly is detached from the reaction vessel, the reaction sealing cover and its stirring assemblies can swing to the side of the open end of the reaction vessel, facilitating cleaning and maintenance of the stirring assemblies and the inner cavity of the reaction vessel. This invention can enhance the mixing effect of raw materials near the inner wall of the reactor, improve the overall mixing efficiency and production quality of the reactor, and use the lifting component to drive the sealing cover to move up and down, eliminating the need for manual handling of the sealing cover and simplifying the operation process.

[0028] Working principle: In actual operation, the stirring component 310 can stir the materials near the inner wall and bottom of the reactor and scrape the wall during the stirring process to prevent the materials from adhering to the inner wall of the reactor for a long time and affecting the subsequent cleaning operation. At the same time, the operating stirring components 14 and 25 can further stir the materials in the reactor, so that the raw materials are fully mixed, improving the overall production quality and work efficiency.

[0029] When it is necessary to open the reaction chamber 6 for cleaning or to repair and maintain the various stirring components, first unscrew the locking nuts on the hinge screws of each locking component and pull out the hinge screws to release the locking connection between the reaction sealing cover 3 and the reaction chamber 6. Then, start the lifting drive component 1-1 in the lifting assembly 1 to move the reaction sealing cover 3 upward. Since the rotating drum 1-2 is rotatably connected to the rotating column 1-3, the operator needs to hold the reaction sealing cover 3 during the movement to ensure its stable ascent and prevent shaking that could cause the stirring components to collide with the lower cylinder structure. Once the lower ends of stirring component 1 4, stirring component 2 5, and stirring component 3 10 have moved above the upper port of the reaction chamber 6... When the reaction sealing cover 3 is in use, it can be pushed to swing around the rotating column 1-3 to the side of the reaction liner 6, which facilitates the cleaning and maintenance of the inner cavity of the reaction liner 6 and the cleaning and maintenance of each stirring component. After the above cleaning and maintenance operations are completed, push the reaction sealing cover 3 to swing and move it to the top of the reaction liner 6. Then, start the lifting drive 1-1 again to move the reaction sealing cover 3 downward. Similarly, during the movement, the staff still needs to hold the reaction sealing cover 3 to keep it descending steadily until the reaction sealing cover 3 is connected and engaged with the reaction liner 6. Then, use several locking parts to lock the reaction sealing cover 3 and the reaction liner 6 to facilitate subsequent reaction operations.
