Description

Technical Field

[0001] This utility model relates to the field of reaction vessels, and more particularly to a reaction vessel for chemical production. Background Technology

[0002] In a broad sense, a reaction vessel is a container that carries out physical or chemical reactions. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries as pressure vessels to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. Examples include reactors, reaction vessels, decomposition vessels, and polymerization kettles. The materials generally include carbon manganese steel, stainless steel, zirconium, nickel-based alloys, and other composite materials.

[0003] Currently, the technology and processes of chemical production reactors have reached a relatively mature stage. However, when adding water to mix with the chemical materials in the reactor, it is difficult to control the flow rate of water into the reactor. At the same time, when discharging the material after mixing, due to the viscosity of the liquid material, some material will adhere to the inner wall of the tank during the discharge process, resulting in material waste and reducing production efficiency. Therefore, a chemical production reactor is proposed to solve the above problems. Utility Model Content

[0028] 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.

[0029] Reference Figure 1 , Figure 2 This utility model provides an embodiment of a chemical production reactor, including a support base 1 and a tank body 2. The inner wall of the support base 1 is fixedly connected to the outer wall of the tank body 2 to ensure the stability of the entire device. The tank body 2 is equipped with an agitation mechanism 11 for stirring the reactants. A replenishment tank 3 is fixedly connected to the top left side of the tank body 2 for easy replenishment of the liquid required for the reaction. An inlet pipe 18 for initial feeding or subsequent material addition is fixedly connected to the top of the tank body 2. The top of the inlet pipe 18 is connected to an external water supply pipe through a flange. An outlet pipe 19 is fixedly connected to the right side of the tank body 2 for easy discharge of reaction products or residual materials. The right side of the outlet pipe 19 is connected to an external pipe through a flange, and the opening and closing of the outlet pipe 19 is controlled by an internal valve. A replenishment mechanism 10 is provided on the outside of the replenishment tank 3.

[0030] Reference Figure 1 , Figure 3 The liquid replenishment mechanism 10 includes a connecting pipe 101 and a stepper motor 103. The connecting pipe 101 is fixedly connected to the top of the liquid replenishment tank 3. A one-way valve 102 for preventing liquid backflow is provided in the middle of the connecting pipe 101. The stepper motor 103 is fixedly connected to the top of the support base 1. A turntable 104 with a circular cross-section is fixedly connected to the front of the output shaft of the stepper motor 103. A connecting rod 105 is hinged to the front of the turntable 104.

[0031] Reference Figure 1 , Figure 3 The connecting rod 105 is hinged to the non-center of the turntable 104. The end of the connecting rod 105 away from the turntable 104 is hinged to a slide rod 106. The slide rod 106 is slidably connected to the inner wall of the replenishment tank 3. The sliding direction of the slide rod 106 is the axial direction of the replenishment tank 3. The end of the slide rod 106 away from the connecting rod 105 is fixedly connected to a pressure plate 107. The pressure plate 107 is slidably connected to the inner wall of the replenishment tank 3. A one-way valve 108 is provided on the surface of the pressure plate 107. By setting the one-way valve 108, the liquid can only enter the tank 2 from the replenishment tank 3 and cannot flow in the reverse direction. The periodic action of the stepper motor 103 realizes the automated liquid replenishment process.

[0032] Reference Figure 1 , Figure 2 The stirring mechanism 11 includes a drive motor 111, which is fixedly connected to the top of the tank 2. The output shaft of the drive motor 111 is fixedly connected to a rotating shaft 112. The stirring mechanism 11 also includes stirring blades 113. The drive motor 111 drives the stirring blades 113 to rotate through the rotating shaft 112. The stirring blades 113 are fixedly connected to the circumferential surface of the rotating shaft 112. The surface of the stirring blades 113 is provided with blades in a curved state. Under the action of the drive motor 111, the stirring is carried out at high speed, which improves the uniformity and efficiency of the reaction.

[0033] Reference Figure 1 , Figure 2 The stirring mechanism 11 also includes a connecting plate 114, which is fixedly connected to the circumferential surface of the rotating shaft 112. A scraper 115 is fixedly connected to one end of the connecting plate 114 away from the rotating shaft 112. The side of the scraper 115 away from the connecting plate 114 contacts the inner wall of the tank 2. The scraper 115 can scrape off the material adhering to the inner wall of the tank 2 while the stirring blades 113 stir the reactants in the tank 2, thereby reducing the amount of material adhering to the inner wall of the tank 2 when the material is discharged and reducing material waste.

[0034] Working principle: In use, the connecting pipe 101 is connected to the external water supply pipe through a flange, and then the required reaction materials are added to the tank 2 through the liquid inlet pipe 18. The drive motor 111 is started to drive the rotating shaft 112 and the stirring blades 113 on it to rotate, which fully stirs the materials in the tank 2. At the same time, the scraper 115 at the end of the connecting plate 114 rotates close to the inner wall of the tank 2, effectively removing the attached materials and ensuring the efficient reaction.

[0035] When liquid needs to be replenished, stepper motor 103 starts working, and turntable 104 on its output shaft rotates accordingly. This, in turn, pushes slide bar 106 to slide axially inside replenishment tank 3 via connecting rod 105, causing pressure plate 107 to compress the liquid inside replenishment tank 3. Due to the presence of one-way valve 108, the liquid can only flow into tank 2 through connecting pipe 101 in a preset direction, while one-way valve 102 ensures that the liquid will not flow back into replenishment tank 3. By controlling the number of rotations of stepper motor 103, quantitative automatic replenishment of liquid is achieved, improving the operational convenience and production efficiency of the reactor. After the material inside tank 2 has reacted completely, the product or remaining material can be easily discharged through liquid outlet pipe 19. The rotation of scraper 115 driven by stepper motor 103 can scrape off the material adhering to the inner wall of tank 2, reducing the amount of material adhering to the inner wall of tank 2 during discharge and reducing material waste.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
