Technical field
The utility model relates to the pay-off in a kind of chemical course of processing, particularly relates to a kind of delivery speed fast, improves the special screw feeding system of high-purity phosphorus oxychloride of transport efficiency.
Background technology
Feed appliance refers to the machine for carrying material, and being common in the conveying to materials such as pellet, powder, sheet material, band material, is all indispensable transmission equipment of light industry or heavy industry.Along with the progress of society, improving constantly of China's Mechanization Level, industrial capacity constantly promotes, and feed appliance also achieves good development.
Traditional conveyor screw is when the material carrying some aqueous ingredientss larger, if barrel connection is poorly sealed, unnecessary moisture can along barrel connection seepage, and moisture also can corrode conveyer parts simultaneously, affects the service life of conveyer.Traditional POCl3 is when operating, and closed-loop operation, notes ventilating.Operate mechanization as far as possible, automation.Operating personal has to pass through special training, strictly observes operating instruction.Suggestion operations personnel wear self-absorbing filtering type gas defence mask (full facepiece mask), wear rubber acid and alkali-resistance clothes, wear rubber acid and alkali-resistance gloves, avoid producing smog.Smog and steam is prevented to be discharged in workplace air.
Due to the special physicochemical property of POCl3, to note avoiding contacting with deoxidation compound, active metal powder, alcohols when production.Especially will note avoiding contacting with water, be equipped with and leak emergency handling equipment, the container of turned letter may remain pest.In existing technology, POCl3 is before Operational preparation, usually put in material storage tube, time to be produced, can directly carry, such as a kind of high-purity phosphorus oxychloride accumulating feeding box disclosed in Chinese patent CN 202080601 U, it is characterized in that: staving aligned on top has the feedback outlet of band material returning valve, the nitrogen inlet of the discharging opening with bleeder valve and band nitrogen valve, although solve in this patent is that operation is loaded down with trivial details at present, apparatus structure is complicated, device cost taken by themselves is high, maintenance cost high (needing special maintenance personnel), and thoroughly can not stop the problem of metallic impurity to the pollution of material, but it is not high for the degree of automation of material conveying itself, therefore the needs in existing production can not still be met.
Utility model content
The technical problems to be solved in the utility model is to provide the special screw feeding system of a kind of high-purity phosphorus oxychloride, can improve transport efficiency, eliminates liquid impurity, ensures the purity of POCl3.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the special screw feeding system of a kind of high-purity phosphorus oxychloride, comprise helical screw feeder, be arranged on the hopper on helical screw feeder, inlet point is provided with above hopper, its innovative point is: described hopper comprises hopper top and hopper body, and inlet point is arranged at hopper top;
Described hopper top and hopper body are the turbination structure that top diameter is less than base diameter;
Also comprise the liquid device being arranged at helical screw feeder inside, liquid device wherein one end connects the engine installation of helical screw feeder outside, and the other end is fixedly installed in helical screw feeder; Described liquid device comprises rotating shaft and is arranged on helicallobe, clutch shaft bearing and the second bearing in rotating shaft, turns the tip of the axis and stretches out respectively outside the hopper top of helical screw feeder.
Further, the back blades that described helical screw feeder comprises main shaft, is arranged at the primary blades on main shaft and is connected with primary blades; Back blades tilts to mass transport direction.
Further, between back blades and primary blades in the angle of 60 ~ 120 °.
The beneficial effects of the utility model:
(1) the special screw feeding system of high-purity phosphorus oxychloride of the present utility model, the helical screw feeder of setting, and the liquid device of helical screw feeder inside, by the motion of liquid device, can eliminate liquid impurity, ensure the purity of POCl3.
(2) the special screw feeding system of high-purity phosphorus oxychloride of the present utility model, hopper is the large structure in little bottom, top, liquid gravitate is not easily bonded at bucket wall, even if liquid is bonded on bucket wall, spiral air flow is formed by the helicallobe in liquid device, drive liquid falls, and indirectly decreases the corrosion condition of POCl3 to equipment inner wall, can improve Liquid transfer efficiency.
(3) the special screw feeding system of high-purity phosphorus oxychloride of the present utility model, angle in 60 ~ 120 ° between back blades and primary blades is set, while effectively can carrying out convey materials, avoid the contact with helical screw feeder itself, reduce equipment damage.
