Abstract

The utility model discloses a flour feed bin prevent device of putting up a bridge, including the rectangle housing of locating feed bin toper outer wall, the opening of rectangle housing covers has the canvas, canvas and rectangle housing constitution air cavity, be equipped with the trachea on the conch wall of rectangle housing, the toper lateral wall of feed bin is equipped with the rectangular hole, the canvas corresponds the cooperation with the rectangular hole, let in the compressed gas in to the rectangle housing through the trachea, the compressed gas makes the canvas vibration, and the canvas of the vibration flour in to the feed bin extrudees, avoids the phenomenon of putting up a bridge, carry out the face contact owing to the canvas is direct with flour, pressure is little, and the canvas has blockked also that the compressed gas gets into the feed bin, and assurance flour can not receive and strikeing strongly, and under even extrusion, the phenomenon can not appear putting up a bridge in the flour in the feed bin, and the unloading is even.

Description

A kind of anti-bridging device of flour feed bin

Technical field

This utility model relates to Flour production apparatus field, the anti-bridging device of a kind of flour feed bin.

Background technology

During Flour production, use elevator that the flour prepared is sent into feed bin, packed by the packer being located at bin bottom again, the usual top of feed bin is the funnel-form that tubbiness, bottom are tapered, owing to the proportion of flour is the lightest, and the reason of its intermolecular distance, the flour being positioned at funnel-form bottom can be layered, there is cavity between layers, the most vertically some places have flour, and some places do not have flour, in industry, this phenomenon are called " bridging ", bridging can cause flour blanking uneven, affects the control of postorder packaging；Common practice is to be passed through compressed air at feed bin sidewall at present, utilizes compressed air to impact flour consumingly, breaks up at bridging, but this mode can cause flour moment avalanche, and blanking is the most out of hand.

Utility model content

The purpose of this utility model is to provide the anti-bridging device of a kind of flour feed bin, this device can be effectively prevented from the bridging phenomenon in feed bin, and ensure uniform blanking.

This utility model solves its technical problem and be the technical scheme is that

The anti-bridging device of a kind of flour feed bin, including being located at the rectangle case of feed bin conical outer wall, the opening of rectangle case is covered with canvas, and canvas constitutes air cavity with rectangle case, and the shell wall of described rectangle case is provided with trachea；The tapered sidewalls of described feed bin is provided with rectangular opening, described canvas and rectangular opening corresponding matching.

The beneficial effects of the utility model are, are passed through compressed gas by trachea in rectangle case, and compressed gas makes canvas vibrate, and the flour in feed bin is extruded by the canvas of vibration, it is to avoid bridging phenomenon；Contacting owing to canvas directly carries out face with flour, pressure is little, and canvas also blocks compressed gas and enters feed bin, it is ensured that flour will not be impacted consumingly, and under uniform extruding, the flour in feed bin does not haves bridging phenomenon, and uniform blanking.

Accompanying drawing explanation

With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings:

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the enlarged diagram in A portion in Fig. 1；

Fig. 3 is the exploded perspective view of Fig. 2；

Detailed description of the invention

Shown in Fig. 1～Fig. 4, this utility model provides the anti-bridging device of a kind of flour feed bin, and including being located at the rectangle case 2 of feed bin 1 conical outer wall, the opening of rectangle case 2 is covered with canvas 3, canvas 3 and rectangle case 2 constitute air cavity 5, and the shell wall of described rectangle case 2 is provided with trachea 4；The tapered sidewalls of described feed bin 1 is provided with rectangular opening 1a, described canvas 3 and rectangular opening 1a corresponding matching.Described anti-bridging device can be uniformly distributed multiple along the conical outer wall of feed bin 1, and quantity is unrestricted.

Being passed through compressed gas in rectangle case 2 by trachea 4, compressed gas makes canvas 3 vibrate after entering air cavity 5, and the flour in feed bin 1, when motion in feed bin 1, is extruded, it is to avoid bridging phenomenon by the canvas 3 of vibration；Contacting owing to canvas 3 directly carries out face with flour, pressure is little, and canvas 3 also blocks compressed gas and enters feed bin 1, it is ensured that flour will not be impacted consumingly, and under uniform extruding, the flour in feed bin 1 does not haves bridging phenomenon, and uniform blanking.

The above, be only preferred embodiment of the present utility model, and this utility model is not made any pro forma restriction；Any those of ordinary skill in the art, without departing under technical solutions of the utility model ambit, technical solutions of the utility model are made many possible variations and modification by the method and the technology contents that all may utilize the disclosure above, or are revised as the Equivalent embodiments of equivalent variations.Therefore, every content without departing from technical solutions of the utility model, to any simple modification made for any of the above embodiments, equivalent, equivalence change and modify according to technical spirit of the present utility model, all still fall within the range of technical solutions of the utility model protection.
