Description

Technical Field

[0001] The utility model relates to the technical field of tin tetrachloride reaction devices, in particular to a reaction device with the function of uniformly heating tin tetrachloride. Background Art

[0002] Anhydrous tin tetrachloride is a colorless, easy-flowing liquid, and the gas molecule is a regular tetrahedral configuration. The bond length is Sn-Cl228pm. The melting point is -33℃, and the boiling point is 114.1℃. The density is 2.226g / cm3. It is miscible with carbon tetrachloride, ethanol, and benzene, and is easily soluble in water, gasoline, carbon disulfide, turpentine, and most other organic solvents. Slowly add water to generate SnO2 colloid and hexachlorostannic acid. When it encounters humid air, it hydrolyzes to generate stannic acid and hydrogen chloride, produces white smoke, and is corrosive. It forms pentahydrate tin tetrachloride with a calculated amount of water. It is used as a mordant and a chlorination catalyst in organic synthesis, and is used for tin plating, etc.

[0003] An existing tin tetrachloride reaction tank includes a reaction tank, and the reaction tank is also provided with an air inlet for conveying chlorine, a feed port for adding tin blocks, and an air delivery port for conveying tin tetrachloride in the reaction tank. During operation, the tin blocks are placed in the feed port, chlorine is conveyed into the reaction tank through the air inlet, and the reaction tank body is heated by a handheld flame spray gun. The chlorine in the reaction tank begins to react with the tin blocks in the feed port to produce tin tetrachloride. Since the reaction process of tin tetrachloride is exothermic, the flame spray gun can be removed at this time. The gaseous tin tetrachloride produced after the reaction is output from the air delivery port, and after the tin blocks have reacted, the tin blocks can be added through the feed port.

[0004] Based on the above, the existing tin tetrachloride reaction tank requires the operator to heat the reaction tank with a handheld flamethrower, which is inconvenient to operate, causes uneven heating, and has low efficiency.

[0005] To this end, a reaction device with uniform heating of tin tetrachloride is proposed, which has the advantage of uniform heating and thus solves the problems in the above-mentioned background technology. Utility Model Content

The installation position of the motor controller is selected according to the actual use requirements, which is convenient for the operator to operate and control. Among them, since the flame coverage range of the flame spray gun is a circular structure, the swing angle of the left flame spray gun 4 and the right flame spray gun 5 should be less than 180 degrees, and the length of the arc clearance port 13 is adapted to the swing angle of the left flame spray gun 4 and the right flame spray gun 5;

[0025] In one embodiment, a fire-gathering portion 3 is integrally cast at the bottom of the reaction tank 1, and the fire-gathering portion 3 is composed of a plurality of surrounding heat-conducting plates 17, and a plurality of heat-conducting arcs 18 are integrally formed on both sides of each heat-conducting plate 17.

[0030] Working principle:

[0031] When in use, firstly, the raw materials (chlorine gas and tin block) required for preparing tin tetrachloride are introduced into the reaction tank 1, and then the reaction tank 1 is extended into the heating shell 2, so that the support ring 7 and the support block 8 are abutted. At this time, by opening the valves 14 of the left flame spray gun 4 and the right flame spray gun 5, and igniting, and then starting the servo motor 11 to rotate forward and reverse, the mounting seat 9 fixed at the output end of the servo motor 11 drives the left flame spray gun 4 and the right flame spray gun 5 to swing at a fixed angle, and the two arc-shaped openings 13 arranged on the outer wall of the heating shell 2 are for the left flame spray gun 4 and the right flame spray gun 5 to swing at a fixed angle. The swing of the right flame spray gun 5 makes way for the left flame spray gun 4 and the right flame spray gun 5 to be adjustable in heating position, thereby realizing uniform heating of the reaction tank 1. Meanwhile, since the fire gathering part 3 is arranged at the bottom of the reaction tank 1, the heat is absorbed by a plurality of heat conducting plates 17 of the fire gathering part 3 and is mutually conducted by a plurality of heat conducting arcs 18, thereby making the bottom of the reaction tank 1 heated more uniformly, so as to further improve the heating effect. When the chlorine gas and the tin block react in the exothermic stage, the valves 14 of the left flame spray gun 4 and the right flame spray gun 5 are closed to stop heating the reaction tank 1.
