Description

Fine powder feeding bin for negative pressure system

Technical Field

The utility model relates to a feed bin technical field especially relates to negative pressure system feeds storehouse with fine powder.

Background

In negative pressure system, need guarantee the air intake, therefore, the feed bin can not seal, but also need guarantee that the feed bin unloading can not mix other debris or large granule material, in addition, this feed bin structure adopts the mode of ton package direct feed to feed in raw material, does not have other pay-off and sieving mechanism before the feed bin feed, consequently, need improve on the comparatively simple feed bin basis of current structure to reach the purpose of guaranteeing that air inlet, material do not have the foreign matter and can directly throw the material.

SUMMERY OF THE UTILITY MODEL

To the above situation, for overcoming prior art's defect, the utility model provides a negative pressure system is with fine powder feed bin solves current feed bin simple structure, can not directly place ton bag and prevent the problem that debris got into under guaranteeing the open-ended prerequisite.

Its technical scheme is, negative pressure system is with fine powder feed bin, including the storehouse body, the storehouse body is uncovered storehouse, internal screen cloth and ton package cross arm of setting in storehouse, the screen cloth top sets up and pushes away the powder frame, it is fretwork frame construction and passes through the pneumatic cylinder drive to push away the powder frame, because this equipment is used in negative pressure system, consequently, need open type design for the device prerequisite, as the fine powder feed bin, then can not use vibration type equipment as the instrument of supplementary unloading, otherwise can cause a large amount of materials to scatter, seriously influence workshop environment and operating personnel are healthy, utilize open type design to place ton package bag in the feed bin top, can save the process of material conveying, practice thrift the cost, the pneumatic cylinder drive pushes away the powder frame round trip movement, prevents that the material from piling up, avoids the raise dust, can push away the large granule material that binds together again.

Furthermore, the bin body inner wall is provided with a mounting frame and is movably mounted with a ton bag cross arm through the mounting frame, the mounting frame is a U-shaped frame with an upward opening, the position of the ton bag cross arm in the bin body can be adjusted according to the size of a ton bag, and when the material residue is less, the material slides out of the ton bag cross arm and falls on the airing net to influence the work of a powder pushing frame and the normal blanking.

Furthermore, a dust collector is arranged at the bin body, so that the production environment sanitation is ensured.

Furthermore, push away crisscross horizontal guide rail and the vertical guide rail that sets up in powder frame below for powder frame can be around the screen cloth side to side motion, and even unloading changes hard friction into sliding friction, reduces equipment wear.

Furthermore, the screen is divided into a plurality of modules to be fixed in the storage bin, so that the screen is convenient to overhaul and maintain.

Furthermore, the screen cloth includes edge screen cloth and central screen cloth, the edge screen cloth has the net frame structure of dead slot for the middle part, in the central screen cloth embedding edge screen cloth and both junctions set up the butt joint groove and can dismantle fixedly through the bolt, the blanking volume is big in the middle of the screen cloth, the reducible screen cloth use cost of this kind of design.

The technical effect of the utility model is that, during negative pressure system farine material adds is applied to this device, the air inlet demand in the negative pressure production has been guaranteed in the open type design, has avoided the material to scatter in the storehouse body of open type design again through pushing away the supplementary unloading of powder frame, prevents simultaneously that debris from getting into, guarantees the precision and the purity of material, provides earlier stage basis for follow-up ration pay-off.
