Description

Technical Field

[0001] The utility model relates to the technical field of chemical reaction containers, in particular to a chemical reaction kettle. Background Art

[0002] In a broad sense, a reactor is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, cooling and low-speed mixing functions required by the process are achieved. Reactors are widely used in the chemical industry, and are generally made of carbon-manganese steel, stainless steel, zirconium, nickel-based alloys and other composite materials.

[0003] In the production process of the chemical industry, chemical reactors play a very important role. A single-axis stirring shaft is usually set in the reactor, and mixing and stirring are carried out by the stirring paddle of the stirring shaft. Single-axis reactors have low stirring efficiency for materials and cannot stir the materials in all directions, resulting in insufficient and uniform stirring and mixing, which in turn makes it impossible for the materials to react in a uniformly mixed state. In this process, how to ensure that the materials are evenly heated and cooled is currently in need of exploration, because this will directly affect the reaction efficiency. In addition, existing chemical reactors are equipped with a discharge pipe for discharging materials after the mixing reaction. When materials are added, the materials will fall into the discharge pipe when the stirring and mixing are not sufficiently uniform. This will not only cause the discharge pipe to accumulate, but also some of the reactants after discharge will not meet the required standards. Therefore, it is necessary to improve it. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a chemical reactor, which has the characteristics of full and uniform stirring and mixing, ensuring uniform heating and cooling of materials, improving reaction efficiency and preventing materials that are not fully stirred and mixed from falling into the discharge pipe.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a chemical reaction kettle, comprising a kettle body, a kettle cover and a bracket, wherein the kettle cover is mounted on the kettle body, the bracket is arranged at the bottom of the kettle body, a feed pipe is arranged on the kettle cover, a gear box is arranged on the top of the kettle cover, an explosion-proof motor is arranged on the top of the gear box, the explosion-proof motor drives a driving shaft, an intermediate stirring shaft is connected to the driving shaft, a driving gear is arranged on the intermediate stirring shaft, a driven gear is meshed with driven gears on both sides of the driving gear, and the driving gear and the driven gear are located in the gear box. The driven gear is integrally provided with a side stirring shaft, the intermediate stirring shaft and the side stirring shaft are provided with propellers, the kettle body is provided with an inner cavity, a spiral coil is provided in the inner cavity, a cooling medium inlet pipe and a cooling medium outlet pipe are provided on the spiral coil, a heat medium inlet pipe and a heat medium outlet pipe are provided on the outside of the kettle body, a discharge pipe is provided at the bottom of the kettle body, a channel, a threaded seat and a side outlet pipe are provided on the discharge pipe, a screw is threadedly mounted on the threaded seat, a blocking disk is provided at the top of the screw, the blocking disk moves in the channel, and a rotary handle is provided at the bottom of the screw.

[0008] As a preferred embodiment of the present invention, a guide slope is provided inside the kettle body, and one end of the guide slope is connected to the channel port.

[0009] As a preferred embodiment of the present invention, the kettle cover is provided with an air pressure measuring and regulating mechanism, which includes a pressure measuring tube, a pressure limiting valve and a pressure gauge, and the pressure limiting valve and the pressure gauge are arranged on the pressure measuring tube located outside the kettle cover.

[0014] By adopting the above technical solution, the advantages of the present invention compared with the prior art are:

[0015] The utility model has a simple and reasonable structure. First, the material is added through the feed pipe, and the explosion-proof motor drives the driving shaft to rotate, so that the middle stirring shaft and the driving gear rotate synchronously. Since the driving gear on the middle stirring shaft is meshed and installed with the driven gear on the side stirring shaft, when the driving shaft rotates clockwise, the middle stirring shaft drives the driven gear to rotate in the opposite counterclockwise direction through the driving gear transmission. The propellers are arranged on the middle stirring shaft and the side stirring shaft, and the propellers are densely distributed in the kettle body. The propellers on the side stirring shaft and the propeller on the middle stirring shaft stir and mix in opposite directions, so that the materials can be stirred in all directions and stirred and mixed fully and evenly.

When heating, , add heat medium through the heat medium inlet pipe, inject it into the inner cavity, and can be discharged through the heat medium outlet pipe. The heat medium can transfer heat to the inside of the kettle, and the heat exchange effect and efficiency are better. When cooling, add cold medium through the cooling medium inlet pipe and inject it into the spiral coil. The spiral coil is close to the kettle body for cooling and is discharged through the cooling medium. This structure can achieve separate control of hot and cold, and can heat or cool the kettle body in all directions to ensure that the material is evenly heated and cooled, thereby ensuring the reaction efficiency and reaction effect; by rotating the operating handle, the screw moves upward, and then the blocking disk blocks the port of the channel to prevent the material that is not fully and evenly mixed from falling into the discharge pipe, preventing the discharge pipe from accumulating, thereby ensuring the discharge of the reactants that are fully and evenly mixed.
