Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, specifically a small to medium-sized temperature-controlled reaction vessel for chemical applications. 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. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. Examples include reactors, reaction vessels, decomposition vessels, and polymerization kettles. Materials generally include carbon manganese steel, stainless steel, zirconium, nickel-based alloys (Hastelloy, Monel, Inconel), and other composite materials. Existing reaction vessels typically only install heating pipes in the jacket of the vessel body to heat the materials inside. This can easily lead to the materials in the center of the reaction vessel not being heated, resulting in a large temperature difference between the inside and outside, and poor temperature control. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a temperature-controlled medium and small-sized chemical reactor, which effectively solves the problem that existing reactors usually only install heating pipes in the jacket of the reactor body to heat the materials inside, which easily leads to the materials in the center of the reactor being difficult to heat and the temperature control effect being poor.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a temperature-controlled medium-sized chemical reactor, comprising a reactor body, with support legs fixedly installed on both sides of the lower part of the reactor body, and pads fixedly installed at the bottom of each support leg; a mounting bracket fixedly installed on the rear part of the reactor body surface; third bushings fixedly installed on both sides of the top of the reactor body; stirring tubes rotatably installed inside each of the two third bushings; both stirring tubes extending into the interior of the reactor body and having several mixing tubes fixedly installed on their surfaces; a rotating tube located in the lower part of the interior of the reactor body; four tilting plates fixedly installed on the surface of the rotating tube; the four tilting plates are made of copper with good thermal conductivity; heating tubes fixedly installed on the two stirring tubes, several mixing tubes, rotating tubes, and the inner lining of the reactor body; a stirring and heating assembly located between the rear and top of the reactor body; and a control panel fixedly installed on the surface of the reactor body, the control panel being electrically connected to several heating tubes.

[0005] Preferably, the stirring and heating assembly includes a motor and a second sprocket. The motor is fixedly mounted on one side of the mounting frame, and a first sprocket is fixedly mounted on the output end of the motor. The second sprocket is located on the upper side of the rear of the reactor body. A chain meshes between the first sprocket and the second sprocket. A second shaft is fixedly mounted on one side of the second sprocket. Two second bushings are rotatably mounted on the surface of the second shaft. A fixing rod is fixedly mounted on the lower part of each of the two second bushings. The bottom of each fixing rod is fixedly connected to the top of the reactor body.

[0006] Preferably, a first bevel gear is fixedly installed at one end of the second shaft, a second bevel gear is meshed with the surface of the first bevel gear, a connecting rod is fixedly installed in the middle of the second bevel gear, worm gears are fixedly installed at both ends of the connecting rod, worm wheels are meshed with the surfaces of the two worm gears, a bearing is rotatably installed at the end of the worm gear away from the connecting rod, a positioning plate is fixedly installed at the ends of the two bearings away from each other, the bottom of the two positioning plates is fixedly connected to the top of the reactor body, and the bottom of the two worm wheels is fixedly connected to the top of the two stirring tubes respectively.

[0007] Preferably, a first shaft is fixedly installed on one side of the first sprocket, one end of the first shaft extends into the interior of the reactor body and is fixedly connected to the rotating tube, and a first bushing is rotatably installed on the surface of the first shaft, and the first bushing is fixedly installed in the lower part of the rear of the reactor body.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator starts the motor through the control panel to drive the first sprocket to rotate. When the first sprocket rotates, it drives the first shaft to rotate along the inside of the first bushing. When the first shaft rotates, it drives the four flipping plates to rotate through the rotating tube to prevent the material from sinking to the bottom. At the same time as the first sprocket rotates, it drives the second sprocket to rotate through the chain. When the second sprocket rotates, it drives the second shaft to rotate along the inside of the two second bushings.

[0009] When the second shaft rotates, it drives the second bevel gear to rotate via the first bevel gear. A connecting rod is fixedly installed in the middle of the second bevel gear. When the connecting rod rotates, it drives two worm gears to rotate along two shaft seats. When the two worm gears rotate, they drive two stirring tubes to rotate via worm wheels. When the two stirring tubes rotate, they drive several mixing tubes to stir the material inside the reactor body. While stirring and turning the material, the heat from the heating tubes in the rotating tubes is conducted to the four tumbling plates and dissipated. The two stirring tubes, several mixing tubes, and the heating tubes in the inner lining of the reactor body simultaneously heat the inside and outside of the material, thereby improving the heating effect. The heat of the heating tubes can be adjusted via the control panel. This allows the reactor to heat the material inside and outside simultaneously, thereby improving the heating uniformity, reducing the temperature difference between the inside and outside, and thus enhancing the temperature control effect.
