Description

Technical Field

[0001] This utility model belongs to the field of chemical production equipment technology, and relates to a reaction device for producing formaldehyde-removing activated manganese. Background Technology

[0002] Current production methods for formaldehyde-removing activated manganese mostly employ batch reactors, which suffer from problems such as poor temperature control accuracy, low production efficiency, and large footprint. Traditional equipment struggles to achieve continuous operation of multi-raw material stepwise reactions, and the coordinated control of reaction flow rate and temperature is ineffective. Furthermore, as manganese has a highly variable valence, the material ratio and reaction temperature have a significant impact on the valence state of the final product. If precise control is not achieved, the quality of the final product cannot be guaranteed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a reaction device for producing formaldehyde-removing active manganese.

[0004] The reaction apparatus for producing formaldehyde-removing activated manganese according to this utility model includes at least two reaction vessels and a mixing reaction tank. The mixing reaction tank is equipped with a mixing feed pipe corresponding to each of the reaction vessels. The reaction vessels are connected to the mixing reaction tank through the mixing feed pipe. A stirring paddle is rotatably connected inside the mixing reaction tank. A stirring motor adapted to the stirring paddle is provided at the top of the mixing reaction tank. A discharge pipe is provided at the bottom of the mixing reaction tank. Both the mixing reaction tank and the discharge pipe are covered with a temperature control jacket. A temperature sensor is provided inside the mixing reaction tank. The temperature sensor is connected to a temperature controller. The temperature controller is connected to the temperature control jacket.

[0005] Working process or working principle:

[0006] During use, according to the production process requirements, appropriate amounts of reactants and water are added to each reactor according to the formula, and the mixture is thoroughly stirred and dissolved. Then, the reactants are fed into the mixing reaction tank through the mixing feed pipe. At the same time, the stirring motor is started to drive the stirring paddle to rotate and stir, so that the mixture is fully mixed and reacted. Then, the appropriate reaction temperature is adjusted by the temperature control jacket. After the reaction is completed, the mixture is discharged through the discharge pipe. During the operation of the mixing reaction tank, other reactors can simultaneously carry out the reaction preparation process. After the mixing reaction tank is completed, the reaction can be repeated immediately, improving work efficiency.

[0007] The discharge pipe is equipped with a discharge valve.

[0008] The discharge pipe is also equipped with a jacketed pipe located below the discharge valve. A temperature sensor is installed inside the discharge pipe. According to different discharge temperature requirements, the medium inside the jacketed pipe is used to achieve heating and cooling, thereby achieving precise control of the discharge temperature.

[0009] The mixing feed pipe is inclined so that the inlet of the mixing feed pipe located in the mixing reaction vessel is aligned with the stirring paddle, which is beneficial to the mixing reaction of materials in each reaction vessel and improves the mixing reaction efficiency.

[0010] The discharge port of the reactor is equipped with a flow control valve, which can control the on / off state and flow rate of each reactor according to the production process and the order of mixing.

[0011] Both the temperature control jacket and the jacket tube are equipped with inlet and outlet pipes, allowing the medium of different temperatures to be introduced into the temperature control jacket and the jacket tube according to the production requirements of different products, thereby achieving the heating or cooling of the discharged material.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention can be connected to multiple separate reactors, ensuring continuous production and improving production efficiency. The discharge temperature is controlled by a temperature control jacket and jacket tube, which is more efficient than the temperature control of a single reactor and can better meet the requirements of precise temperature control. Compared with intermittent devices, this equipment occupies less space. It automatically adjusts the flow rate for more precise control. Attached Figure Description
