Abstract

The utility model provides the upper end that a special solid powder material charging means, charging ladle's end opening pass through rubber tube and metal inlet tube links to each other, the middle part slope intercommunication of metal inlet tube lower extreme and vertical unloading pipe, the lower extreme of unloading pipe with observe the bucket and link to each other, have a puddler in the unloading pipe, did unloading pipe upper portion have 10 during the puddler stretched into and observes the bucket 15cm's flexible coupling section is connected with the nitrogen gas input tube on the observation bucket, observes the bucket and communicates through ball valve, ring flange and reation kettle. When feeding in raw material, filling lithium aluminium hydride with charging ladle earlier, then linking to each other charging ladle end opening and rubber tube upper end, the lithium aluminium hydride powder passes through rubber tube, metal inlet tube, unloading pipe, observation bucket, ball valve, ring flange entering reation kettle, in the time of the unloading, imports nitrogen gas from observe the bucket, rocks the puddler and can make the unloading more smooth and easy, and the flexible coupling section is convenient for rock the puddler, and whole unloader becomes closed state, does not have the lithium aluminium hydride departure. The utility model discloses improve the operational environment of unloading greatly, stopped to fire the accident.

Description

A kind of special solid powder material feeder

Technical field

This utility model is related to chemical industry, pharmaceutical equipment, i.e. a kind of special solid powder material feeder.

Background technology

Lithium Aluminium Hydride is a kind of pressed powder, proportion very little, during charging, easily flies upward in atmosphere, in south Under conditions of Fang Gaowen, humidity, easily cause hydrogen to fire, cause the accident.Workman is adding tetrahydrochysene aluminum in reactor at present During lithium, fastened in reactor plastic bag suitable for reading by one, manually topple over Lithium Aluminium Hydride in plastic bag, more unavoidably four Hydrogen aluminum lithium powder flies upward out from plastic bag is suitable for reading, and on the one hand the body of pollution workman and medicated clothing, are on the other hand also easy to draw Play hydrogen to fire, cause the accident.

Content of the invention

For unsafe shortcoming when overcoming current Lithium Aluminium Hydride charging, the utility model proposes a kind of special solid powder The new design of last material feeder.

This special solid powder material feeder, the charging ladle including top is it is characterised in that the lower mouth of charging ladle leads to The upper end crossing rubber tube with metal introducing pipe is connected, and metal introduces pipe lower end and tilts to connect with the middle part of vertical tremie pipe, under The lower end of expects pipe is connected with observing bucket, has a puddler in tremie pipe, and puddler stretches in observation bucket, and 10- is arranged at tremie pipe top The section that is flexible coupling of 15cm, observes and is connected with nitrogen input pipe on bucket, observes bucket and is connected with reactor by ball valve, ring flange.

Observe bucket and include upper and lower two little flanges, be a transparent plastic barrel in the middle of two little flanges, little flange and thoroughly Bright plastic barrel is connected by screw rod.The situation of blanking can clearly be observed by transparent plastic barrel.

During charging, first charging ladle is filled Lithium Aluminium Hydride, then mouth under charging ladle is connected with rubber tube upper end, tetrahydrochysene aluminum Lithium powder passes through rubber tube, metal introduces pipe, tremie pipe, observation bucket, ball valve, ring flange enter reactor, while blanking, from Observe in bucket and input nitrogen, rocking puddler can make blanking more smooth, and the section that is flexible coupling is easy to rock puddler, whole blanking dress It is set to closed state, do not have Lithium Aluminium Hydride and fly out.

This utility model substantially improves the working environment of blanking, has prevented blast accident.

Brief description

Fig. 1 is structural representation of the present utility model

In figure: 1, charging ladle, 2, rubber tube, 3, metal introduce pipe, 4, tremie pipe, 5, observe bucket, 6, puddler, 7, soft company Connect section, 8, nitrogen input pipe, 9, ball valve, 10, ring flange, 11, reactor, 12, little flange, 13, transparent plastic barrel, 14, spiral shell Bar.

Specific embodiment

Below in conjunction with the accompanying drawings this utility model is described in detail as follows:

In FIG, this special solid powder material feeder, including the charging ladle 1 on top, the lower mouth of charging ladle 1 leads to The upper end crossing rubber tube 2 with metal introducing pipe 3 is connected, and metal introduces pipe 3 lower end and the middle part of vertical tremie pipe 4 tilts even Logical, the lower end of tremie pipe 4 is connected with observing bucket 5, has a puddler 6 in tremie pipe 4, and puddler 6 stretches in observation bucket 5, blanking The section 7 that is flexible coupling of 10cm is arranged at pipe 4 top, observes and is connected with nitrogen input pipe 8 on bucket 5, observes bucket 5 and passes through ball valve 9, ring flange 10 Connect with reactor 11.

Observe bucket 5 and include upper and lower two little flanges 12, be a transparent plastic barrel 13 in the middle of two little flanges 12, little method Orchid 12 and transparent plastic barrel 13 are connected by screw rod 14.The feelings of blanking can clearly be observed by transparent plastic barrel 13 Condition.
