Abstract

The utility model relates to a continuous batched solid material feeding device, which is characterized by comprising a feeding hopper, a feeding pipe, a threaded connecting rod, an elastic sleeve, a spring ring and a seal shaft, wherein a feed port, a gas outlet and a connecting rod hole are formed in the upper end of the feeding hopper, and a gas inlet is formed in the side wall of the feeding hopper; one end of the feeding pipe is communicated with the lower end of the feeding hopper, and the other end thereof is communicated with the upper end port of the elastic sleeve; the spring ring is wound on the lower end port of the elastic sleeve in a sleeving manner; the threaded connecting rod extends into the feeding hopper via the connecting rod hole and is inserted into the feeding pipe; and the seal shaft is mounted between the threaded connecting rod and the connecting rod hole. The device has the advantages that the feeding rate can be controlled, the solid raw material can be fed at a constant speed, and air and steam can be prevented from entering the solid raw material during feeding.

Description

A kind of continuous batch solid feeding device

Technical field

The utility model relates to a kind of solid feeding device, especially is applied in the process that feeds intake between the high solid of reactivity and the liquid, can control the continuous batch solid feeding device of the reaction speed of entire reaction simultaneously.

Background technology

In the reaction between some solids and liquid, if the control fluid drips is added in the solid go at present, can directly use dropping funel to operate, not only can feed in raw material continuously, also can control charging rate; But sometimes to control solid and join dereaction in the liquid lentamente, if reaction is to open wide system, then can join in the reaction system in batch with little spoon or spoon, but this can only be applicable to needn't secluding air reaction, manual operations simultaneously also can't be controlled reinforced speed effectively.

For namely controlling charging rate, guarantee the reinforced operation of solid under the secluding air condition again, generally adopt dual mode: operate in inert atmosphere glove box or bag glove (1).This operation requires very high to equipment, process is also very loaded down with trivial details; (2) adopt the device of Schlenk technology to operate, this is the feeding technique of solid chemical compound during a kind of more convenient anaerobic anhydrous response commonly used is operated; Control the interpolation solid reactant by the height and position that rotates reinforced bottle, thereby reach the purpose of control charging rate; But some liquid reactants in reaction bulb or solvent the time can produce certain steam in heating, and steam rising meeting contact with the solid powdery reactant that is adding, cause and form further transfer of block influence, even react on the surface etc.

Summary of the invention

At above-mentioned shortcoming, the purpose of this utility model is to provide a kind of continuous batch solid feeding device, its can be implemented under the situation of secluding air with the solid small lot join in the liquid and react, can prevent effectively that also solid reactant from contacting with reaction solution steam, simultaneously can also control reinforced speed, make reinforced at the uniform velocity and easy to control.

Technology contents of the present utility model is that a kind of continuous batch solid feeding device is characterized in that it comprises charging hopper, charge pipe, threaded connecting rod, spring-backed quill, turn and seal shaft; Be provided with a charge door, gas vent and tie rod holes in the charging hopper upper end, be provided with a gas feed at the charging hopper sidewall; Charge pipe one end is communicated with the lower end of charging hopper, and the charge pipe other end is communicated with the spring-backed quill upper port, the rich lower port that is enclosed within spring-backed quill of turn; Threaded connecting rod stretches in the charging hopper by tie rod holes and is inserted in the charge pipe, between threaded connecting rod and the tie rod holes seal shaft is housed.

The advantage that the utility model compared with prior art has is, the utility model can be controlled threaded connecting rod rotating speed indirectly by the variable resistor of controlling manual rocking handle or outside, control the reinforced speed of solid thus, owing to can prevent that in the rich lower port that is enclosed within spring-backed quill of turn air and steam from entering into solid material and going, whole feeding device simple structure is easy to operate simple.

Specific embodiment

As shown in Figure 1, a kind of continuous batch solid feeding device is characterized in that it comprises charging hopper 1, charge pipe 2, threaded connecting rod 3, spring-backed quill 4, turn 5 and seal shaft 6; Be provided with a charge door 1.1, gas vent 1.2 and tie rod holes 1.3 in the reinforced 1 bucket upper end of leaking, be provided with a gas feed 1.4 at charging hopper 1 sidewall; Charge pipe 2 one ends are communicated with the lower end of charging hopper 1, and charge pipe 2 other ends are communicated with spring-backed quill 4 upper port, and turn 5 is around the lower port that is enclosed within spring-backed quill 4; Threaded connecting rod 3 stretches in the charging hopper 1 by tie rod holes 1.3 and is inserted in the charge pipe 2, between threaded connecting rod 3 and the tie rod holes 1.3 seal shaft 6 is housed.

Operation principle of the present utility model is that by in the charge door 1.1 input funnels 1, inert gas is imported by gas feed 1.4, and flows out from gas vent 1.2 with solid material in elder generation; When reinforced, just move by wind 7 or by motor rotating band threaded rod 3, by threaded connecting rod 3 solid material is leaked 1 by in the charge pipe 2 extruding input flexibility sleeve pipes 4 from reinforced, solid material struts after the lower port of cover by the spring-backed quill 4 of turn 5 and exports, threaded connecting rod 3 just stops operating when stopping to feed in raw material, this moment is under the effect of turn 5, the lower port envelope of spring-backed quill 4 is tight, prevent that thus air and steam from entering into solid material and going.
