Description

Full-open type rake formula stirring vacuum drier

Technical field:

The utility model relates to the drying machinery technical field, and exactly, it is a kind of full-open type rake formula stirring vacuum drier.

Background technology:

Drying machine is one of pharmaceutical industry equipment commonly used, is mainly used in the drying of solid, liquid attitude mixed material and the recovery of solvent thereof, under the vacuum state, can reduce baking temperature.Existing rake formula stirring vacuum drier pass the axis at dryness storehouse two ends by decelerator, the totally enclosed dryness storehouse in two ends, one substantially and be installed in the rake teeth on the axis and be installed on the rake teeth the hammering bar construction.Find in the use that the drying machine of this structure mainly exists following deficiency:

1, because except that charging aperture, drain hole and trap mouth and other pipe joint, the dryness storehouse complete closed, when dryness storehouse in the use need clean or sterilize, can only enter from the charging aperture at dryness storehouse top, not only labour intensity is big, cleaning quality is poor, and required scavenging period is long, operating efficiency is low; The material that the end-on burst accident is set in the warehouse then can't be brought down stocks substantially.

2, in the dry materials process, the hammering rod between rake teeth will be set in material fragmentation together, and the strong friction, the metal fragment that produce between metal material during owing to hammering come off, and very easily cause heavy metal severe overweight in the material that is dried; More can not be used for dry inflammable and explosive material.

3, the bearing block at warehouse two ends adopts packing seal more, and encapsulant produces and grinds chip in the course of work, easily material is polluted.

Summary of the invention:

The utility model is the technological improvement to existing rake formula stirring vacuum drier, and its purpose just provides a kind of easy cleaning sterilization, free of contamination full-open type rake formula stirring vacuum drier.

The purpose of this utility model is to realize like this.Full-open type rake formula stirring vacuum drier comprises warehouse, door, semiaxis, main bearing seat, rake teeth and rolls beam, charging aperture (12) be arranged on warehouse (10) above, rake teeth (14) is installed on the semiaxis (15), it is characterized in that: an end of warehouse (10) is equipped with door (16), drain hole (20) is installed in the bottom of door (16), main bearing seat (21) is installed in the other end of warehouse (10), and countershaft bearing (3) is supported on the tail end of semiaxis (15), and semiaxis (15) is driven by motor (1); The side of warehouse (10) is provided with axle sleeve (24), and door (16) utilizes crossbeam (17) and bearing pin (25) pin to be contained on the axle sleeve (24), and the tight mechanism of fine jade (19) is housed on the door (16), and screwing mechanism (19) is screwed on the warehouse crossbeam (18); Be equipped with on the rake teeth (14) and roll beam (11); Flexible sealing (8) and rigid seal (7) are housed in the main bearing seat (21), and bearing (6) is installed in the outside of seal section; Semiaxis (15) is connected on the drive sprocket (23) of reductor (2) output by driven sprocket (4) and chain.Trap (13) can be installed in warehouse (10) above, the skin of warehouse (10) can covering and heat insulating layer (9).

Compared with prior art, the utility model adopts the full-open type structure that door is set at an end of warehouse, door is opened flexible, after opening door, the material of thing and agitating device come out fully in the storehouse, be convenient in the storehouse to clean, sterilization, can remove the material that solidifies in the storehouse, in case of necessity can also 100% ground recovery bin in precious solid, liquid attitude material; The equipment of also being convenient to is more simultaneously installed and maintenance.After a side setting of rake teeth rolls beam, can produce material and impact and roll effect, cooperates with rake teeth, roll, the effect of fragmentation is stronger, and thoroughly solved because of metal dust comes off, cause the problem of the material heavy metals exceeding standard that is dried.Semiaxis and hermetically-sealed construction gentle, combination just have not only reduced seal point, and favorable sealing property, nothing grind chip and produce, thereby avoided grinding debris contamination material.
