Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a novel glass-lined reactor with a built-in baffle. Background Art

[0002] Glass-lined reactor is a common equipment used in chemical laboratories. It is corrosion-resistant and high-temperature resistant. When the viscosity of the liquid in the reactor is not high and the speed of the agitator is high enough, a vortex flow or "cylindrical swirl zone" is easily generated in the reactor tank, which makes the liquid level in the center of the tank concave and the surrounding liquid is lifted above the average liquid level. The vortex flow is generated when centrifugal force acts on the rotating liquid. As the speed of the agitator increases further, the liquid level concave and contacts the impeller, bringing in a large amount of air, the power decreases, and the mixing efficiency decreases accordingly. For the mixing of materials in a multiphase system, due to the centrifugal force, not only can the materials in the multiphase system not be mixed, but the materials in the multiphase system are stratified or separated, so that the solid particles in the multiphase system are thrown to the wall of the reactor and then deposited on the bottom of the reactor along the wall. In addition, the violently swirling liquid combined with the vortex action will also cause abnormal liquid force, which will impact the stirring shaft and aggravate the stirring vibration, thereby affecting the service life of the agitator or even making it impossible to operate. In order to eliminate the "cylindrical swirl zone" and swirling phenomenon in the turbulent state, baffles or guide tubes are usually installed in the reactor.

[0003] In the reactor disclosed in the publication number CN205886851U, a temperature measuring device is provided at the top of the reactor body, the lower end of the temperature measuring device extends to the lower part of the reactor body, and the inner surface of the reactor body is provided with a glass lining layer that is resistant to low temperature and acid and alkali corrosion. The reactor is resistant to both low temperature and acid and alkali corrosion.

[0004] However, this reactor has the following disadvantages:

[0005] (1) When the staff uses the reactor to carry out the reaction, the stirrer speed may be too fast, and the centrifugal force may reduce the mixing of the materials. The reactor is not convenient for controlling the stirrer speed, which reduces the applicability of the reactor;

[0006] (2) When the staff uses the reactor to carry out reactions, since different reactions have different reaction speeds at different temperatures, the reactor is not convenient for adjusting the heating temperature to control the reaction speed, which reduces the degree of reaction adequacy.

[0013] Through the above technical solution and the setting of the temperature controller, the purpose of controlling the heating temperature of the heating wire is achieved.

[0014] As a further improvement of the above solution, an input pipe is connected through one side of the shell, an output pipe is connected through one side of the surface of the shell close to the input pipe, and an A valve is fixedly connected to one end of the output pipe.

[0015] Through the above technical solution, by setting the input pipe and the output pipe, the staff can add heat transfer oil into the cavity between the shell and the kettle body.

[0016] As a further improvement of the above solution, the bottom of the kettle body is connected with a conical cylinder, the bottom of the conical cylinder is connected with a B valve, and the bottom of the B valve is connected with a guide pipe.

[0017] Through the above technical solution, by setting the B valve and the guide pipe, the purpose of facilitating the discharge of the reaction products is achieved.
