Abstract
The utility model relates to a dust flying prevention device which comprises a cover plate arranged at an opening above a middle hopper; a clearance exists between the cover plate and a blanking pipe, and an annular sealing piece is arranged between the cover plate and the side surface of the middle hopper. The dust flying prevention device effectively prevents the phenomenon of dust flying when powder material is added into the middle hopper from a storage barrel, thus effectively improving the working environment, and simultaneously avoiding the potential quality risk of products caused by the variation of components of the powder material due to dust flying.
Description
Technical field
The utility model relates to a kind of device that prevents dust from flying, is to prevent that powder is from the dust from flying of storage vat when middle hopper adds powder.
Background technology
Powder metallurgy is the technology of studying and making various metal powder materials and make metalwork with the compound of metal powder material or metal powder material and non-metal powder by shaping and sintering.The production process of powder metallurgical product is: mixing → shaping → sintering → subsequent treatment, on forming process, adding frit materials to middle hopper is a requisite action.Because the material that uses is a powder, in the process that falls, if not in addition actv. protection, be certain to produce the dust from flying phenomenon, influence Products Quality and abominable on-the-spot working environment, so prevent dust from flying, this is the target that a powder metallurgical product manufacturer is pursued to optimize working environment, also is stubborn problem the most.General way is to add a cover a stainless steel cover on middle hopper now, but also has certain interval between this method stainless steel cover and the middle hopper, and dust still flies out from both gap locations easily.
The utility model content
The utility model is at above-mentioned defective, and purpose is to provide a kind of powder that prevents effectively to produce the anti-dust from flying device of dust from flying from storage vat when middle hopper adds powder.
The technical solution of the utility model is: the utility model comprises the cover plate that is arranged on middle hopper top opening part, has the gap between cover plate and the tremie pipe, establishes lip ring between cover plate and the middle hopper side.
Further, the foam seal cover of ring set on tremie pipe established in the cover plate top.
Further, establish the glass cement sealing between cover plate and the middle hopper side.
The utility model has the advantages that: the 1) interface of stainless steel cover on middle hopper and middle hopper glass cement ring seal, with glass cement leak free purpose one is to prevent that dust from flying upward out from middle hopper, the 2nd, and the glass cement sealing can realize the non-destructive separation; 2) storage vat seals with foam encasement to the tremie pipe of middle hopper and the interface of middle hopper, purpose is to utilize the gap of foam allow in the air admission middle hopper, in order to avoid the middle hopper cavity volume forms vacuum, guarantee that the powder of middle hopper is wandered in the feeding boots smoothly.
According to above-mentioned explanation, the utility model actv. has prevented the phenomenon of the dust from flying when powder is added in middle hopper from storage vat, thereby improved working environment effectively, avoided flying upward of dust to cause the variation of powder composition simultaneously and cause the potential quality risk of product quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is storage vat, the 2nd among the figure, tremie pipe, the 3rd, foam seal cover, the 4th, cover plate, the 5th, close glass cement, the 6th, middle hopper.
The specific embodiment
The utility model comprises the cover plate 4 that is arranged on middle hopper 6 top opening parts, has the gap between cover plate 4 and the tremie pipe 2, establishes lip ring between cover plate 4 and middle hopper 6 sides, and lip ring of the present utility model is preferentially selected glass cement 5 for use.
Further, the utility model is being established the foam seal cover 3 of ring set on tremie pipe 2 above the cover plate 4.
Working process of the present utility model is that powder enters middle hopper 6 from storage vat 1 blanking through tremie pipe 2, realizes feeding.
Claims (3)
1. anti-dust from flying device comprises the cover plate that is arranged on middle hopper top opening part, has the gap between cover plate and the tremie pipe, it is characterized in that, establishes lip ring between cover plate and the middle hopper side.
2. anti-dust from flying device according to claim 1 is characterized in that, the foam seal cover of ring set on tremie pipe established in the cover plate top.
