Description
Technical field
The utility model relates to a kind of distillation still, specifically a kind of distillation still with backflow cleaning device of producing in pivaloyl chloride technique.
Background technology
Distillation is a kind of conventional method of separation, purifying liquefied mixture, also can measure the boiling point of liquefied compound, therefore has certain meaning to the pure liquefied compound of qualification.Still-process needs heating, consumes a large amount of heats, the stable heating of process need of distillation procedure, thermal starting is fast, good heat insulating, produces and needs through distilation in pivaloyl chloride technique, in existing purification process, gas rises in still, is filtered by filling container, again through condenser condenses, impurity in gas can be stayed in filling container after the filtration of filling container, after a period of time, due to the accumulation of impurity, have to clear up through row filling container, cause the stopping of producing.
Utility model content
The purpose of this utility model is to provide a kind of distillation still with backflow cleaning device of producing in pivaloyl chloride technique, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of distillation still with backflow cleaning device of producing in pivaloyl chloride technique, described distillation still body upper end is provided with charging aperture, described distillation still body lower end is provided with discharging opening, the inwall of described distillation still body is provided with zone of heating, heat(ing) coil is provided with in described zone of heating, described base is provided with motor, described motor is connected with reductor, the output shaft of described reductor connects the intrinsic shaft of distillation still, described shaft is provided with receiver and helical blade, described backflow cleaning device comprises filling container, first condenser, catch tray and the second condenser, described distillation still body upper end is provided with gas vent, described gas vent is communicated with filling container, described filling container upper end is connected with the first condenser is vertical, described first condenser is connected with the second condenser is vertical, described first condenser and the second condenser junction are provided with catch tray.
As further program of the utility model: mounting seat under described distillation still body.
As the utility model further scheme: described receiver is arranged on the top of helical blade.
As the utility model further scheme: described catch tray one end is provided with liquid outlet.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, by the inwall side at distillation still body, zone of heating is set, can make to be heated during heating material more even, improve the efficiency of heating surface, material is stirred by the agitating device arranged at distillation still body bottom portion, avoid material local temperature too high, heat more even, distilling effect is better, the receiver arranged makes the material dispersion putting into distillation still body even, prevent local concentration too high, improve product quality, the backflow cleaning device arranged carries out partial condensation by low power first condenser to the gas produced in distillation still body, thus make liquid material be back in distillation still body, and filler in filling container is cleaned, the service time of filler is extended greatly, from monthly must carry out clearing up once in the past, extend to three months and carry out cleaning once, liquid material simultaneously after backflow, after distilation, color and luster is fuller.
Accompanying drawing explanation
Fig. 1 is the structural representation of the distillation still with backflow cleaning device of producing in pivaloyl chloride technique.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of distillation still with backflow cleaning device of producing in pivaloyl chloride technique, comprise base 1, distillation still body 2 and backflow cleaning device, described distillation still body 2 upper end is provided with charging aperture 14, described distillation still body 2 lower end is provided with discharging opening 15, the inwall of described distillation still body 2 is provided with zone of heating 5, heat(ing) coil 6 is provided with in described zone of heating 5, described distillation still body 2 times mounting seat 1, described base 1 is provided with motor 17, described motor 17 is connected with reductor 16, the output shaft of described reductor 16 connects the shaft 4 in distillation still body 2, described shaft 4 is provided with receiver 7 and helical blade 3, described receiver 7 is arranged on the top of helical blade 3, described backflow cleaning device comprises filling container 9, first condenser 10, catch tray 11 and the second condenser 12, described distillation still body 2 upper end is provided with gas vent, described gas vent is communicated with filling container 9, described filling container 9 upper end is connected with the first condenser 10 is vertical, described first condenser 10 is connected with the second condenser 12 is vertical, described first condenser 10 and the second condenser 12 junction are provided with catch tray 11, described catch tray 11 one end is provided with liquid outlet 13.
The utility model structure is simple, by the inwall side at distillation still body 2, zone of heating 5 is set, can make to be heated during heating material more even, improve the efficiency of heating surface, material is stirred by the agitating device arranged bottom distillation still body 2, avoid material local temperature too high, heat more even, distilling effect is better, the receiver arranged makes the material dispersion putting into distillation still body 2 even, prevent local concentration too high, improve product quality, by low power first condenser 10, partial condensation is carried out to the gas produced in distillation still body 2, thus make liquid material be back in distillation still body 2, and filler in filling container 9 is cleaned, the service time of filler is extended greatly, from monthly must carry out clearing up once in the past, extend to three months and carry out cleaning once, liquid material simultaneously after backflow, after distilation, color and luster is fuller.
