[0008] In view of the defects in the prior art, the utility model solves the problem that in the preparation and synthesis process of sodium chlorite in the traditional technology, various materials inside are restricted by the influence of the internal mixing component and are easy to flow in a fixed direction, and various materials cannot be quickly and fully stirred and mixed; and raw materials need to be continuously added during the process, which makes it easy for the internal irritating gas to leak out when adding materials, causing harm to the human body or the environment.

[0009] In order to solve the above problems, the utility model provides the following technical solutions:

[0010] A sodium chlorite synthesis reactor comprises a kettle body, wherein a separation cylinder is coaxially fixedly connected to the kettle body, an inner flow channel is formed through the inner cavity of the separation cylinder, an outer flow channel is formed between the outer wall of the separation cylinder and the inner wall of the kettle body, and the upper and lower ends of the inner flow channel and the outer flow channel are both connected to the inner cavity of the kettle body.

[0011] A main spiral conveying blade is provided for rotation in the inner flow channel, and a secondary spiral conveying blade is provided for rotation in the outer flow channel. The main spiral conveying blade and the secondary spiral conveying blade are arranged to rotate synchronously, and the thread rotation direction of the main spiral conveying blade is opposite to the thread rotation direction of the secondary spiral conveying blade.

[0013] As an optimized solution, a feed barrel is fixedly connected to the top of the kettle body, and two flap valves are arranged in parallel from top to bottom in the feed barrel.

[0014] As an optimized solution, rectangular guide holes are horizontally opened on the bottom mixed flow blade.

[0015] As an optimized solution, the upper and lower edges of the rectangular guide hole are inclined.

[0016] As an optimized solution, the inner bottom surface of the kettle body is concavely arranged, and the lower end of the bottom mixed flow blade matches the inner bottom surface of the kettle body.

[0017] As an optimized solution, a discharge valve connected to the inner cavity of the kettle body is fixedly connected to the bottom of the kettle body, and the discharge valve is located at the center of the bottom of the kettle body.

[0018] As an optimized solution, a main shaft is vertically rotated in the kettle body, and two bottom mixed flow blades are oppositely arranged, and the inner ends are fixedly connected to the opposite side walls of the main shaft near the lower end.

[0019] As an optimized solution, the inner edge of the main spiral conveying blade is fixedly connected to the main shaft, and the outer edge of the main spiral conveying blade is in frictional contact with the inner wall of the partition cylinder.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] The main shaft is driven to rotate by the driving machine, thereby driving the main blade of the spiral conveying and the auxiliary blade of the spiral conveying to rotate. Since the thread rotation direction of the main blade of the spiral conveying is opposite to the thread rotation direction of the auxiliary blade of the spiral conveying, the flow direction of the materials in the inner flow channel and the outer flow channel is reversed, thereby improving the mixing uniformity of the internal materials. The main shaft is controlled by the driving machine to rotate forward and reverse, thereby realizing the conversion of the flow direction of the materials in the inner flow channel and the outer flow channel, thereby improving the mixing uniformity of various materials. The lower end of the main shaft is connected to the bottom mixing blade to realize stirring and mixing of the materials flowing to the bottom. By setting a rectangular guide hole and slanting the upper and lower edges, secondary guide mixing of the materials is realized, thereby greatly improving the mixing uniformity of various materials.

[0024] By arranging two flap valves in parallel from top to bottom on the feed barrel, when adding materials or additives into the kettle body, the two flap valves are opened alternately, which can prevent the internal toxic gas or irritating gas from leaking out and prevent harm to the human body or the environment.
