Abstract
The utility model discloses a storage silo exhaust device, which is arranged at the lower position of the bottom in a storage silo; the method is characterized in that: the air guide sleeve is of a conical structure, the large-diameter end of the air guide sleeve is positioned at the bottom of the storage bin, and the center line of the air guide sleeve is superposed with the center line of the storage bin; the upper end part of the air guide sleeve is connected with an exhaust pipe, and the exhaust pipe extends upwards to the outside of the storage bin in an inclined mode; the exhaust pipe is fixedly arranged in the storage bin through a support frame, and the end part of the outer edge of the support frame is fixedly connected with the inner wall of the storage bin. By adopting the technical scheme, the material discharging process in the storage bin can be stabilized, the fluctuation of the discharging amount is reduced, the moisture stability rate of the sintering material is improved, and the quality of the sintering ore is improved.
Description
Technical Field
The utility model belongs to the technical field of smelt, especially, relate to a storage silo exhaust apparatus.
Background
In the sintering production process, a storage bin for materials such as quicklime, dedusting ash and the like is closed, and the materials are loaded into the storage bin through pneumatic conveying. The materials in the storage bin move from top to bottom and finally fall onto the belt through the discharge hole to participate in sintering production along with other sintering materials. In the actual production process, when the gas that gets into in the storage silo along with pneumatic conveying fails to pass through the exhaust apparatus on feed bin upper portion and all discharges, partial gas can move down and the downstream along with the material, when gas motion to storage silo lower part and feed opening position, under the pressure effect of material around, the convergence gathers and forms high-pressure gas, because storage silo inside and outside pressure differential are great, this just leads to the material can rush out the feed opening in the twinkling of an eye and carry a large amount of material at the unloading in-process, cause the unloading volume grow in the twinkling of an eye, gaseous blowout back, the storage silo lower part is unsettled in the twinkling of an eye, the atress structural change, the unsettled material of bottom moves down fast under upper portion material pressure, again exert an influence to the unloading volume, the fluctuation of material unloading not only can cause the change of sintering material moisture, also produce adverse effect to sintering.
SUMMERY OF THE UTILITY MODEL
Problem to prior art existence, the utility model provides a stabilize material unloading process in storage silo reduces the fluctuation of unloading volume, improves sintering material moisture stable rate, improves the storage silo exhaust apparatus of sintering deposit quality.
The utility model is realized in such a way that the exhaust device of the storage bin is arranged at the lower position of the bottom in the storage bin; the method is characterized in that: the air guide sleeve is of a conical structure, the large-diameter end of the air guide sleeve is positioned at the bottom of the storage bin, and the center line of the air guide sleeve is superposed with the center line of the storage bin; the upper end part of the air guide sleeve is connected with an exhaust pipe, and the exhaust pipe extends upwards to the outside of the storage bin in an inclined mode; the exhaust pipe is fixedly arranged in the storage bin through a support frame, and the end part of the outer edge of the support frame is fixedly connected with the inner wall of the storage bin.
In the above technical solution, preferably, a filter screen is arranged at a connection position of the air guide sleeve and the exhaust pipe.
In the above technical solution, preferably, the mesh number of the filter screen connected to the air guide sleeve and the exhaust pipe is 30-200 meshes.
In the above technical solution, preferably, a filter screen is disposed at an outer end of the exhaust pipe.
In the above technical solution, preferably, the mesh number of the filter screen at the outer end of the exhaust pipe is 200-800 meshes.
The utility model has the advantages of technological effect: compared with the prior art, the utility model, stabilize material unloading process in the storage storehouse, reduce unloading volume fluctuation, improve sintering material moisture stable rate, improve the sinter quality.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, an exhaust device for a storage bin is installed at a position below the bottom of the storage bin; the air guide sleeve is of a conical structure, the large-diameter end of the air guide sleeve is positioned at the bottom of the storage bin 2, and the center line of the air guide sleeve is superposed with the center line of the storage bin; the upper end part of the air guide sleeve is connected with an exhaust pipe 3, and the exhaust pipe extends upwards to the outside of the storage bin in an inclined mode; in the storage bin, the exhaust pipe is fixedly installed through a support frame 4, and the end part of the outer edge of the support frame is fixedly connected with the inner wall of the storage bin.
In the above technical scheme, preferably, a filter screen 5 is arranged at the joint of the air guide sleeve and the exhaust pipe, and the filter screen can filter partial materials carried in the gas and return the materials to the stock bin.
In the above technical solution, preferably, a filter screen is arranged at a connection position of the air guide sleeve and the exhaust pipe.
In the above technical solution, preferably, the mesh number of the filter screen connected to the air guide sleeve and the exhaust pipe is 30-200 meshes.
In the above technical solution, preferably, the filter screen 6 is installed at the outer end of the exhaust pipe, and the mesh number of the filter screen installed at the outer end of the exhaust pipe is 200-800 meshes, so as to prevent dust from leaking and exhaust air at the same time.
When the material of storage silo lower part is removing when exhaust apparatus gas kuppe position during production, the gaseous kuppe that gets into of inclusion in the material, and the material that carries in the gas passes through filter screen and the sealed fall back of gas vent to the feed bin in, and gas is through exhaust pipe and gas vent discharge outside the storehouse. Compared with the prior art, the utility model, stabilize material unloading process in the storage storehouse, reduce unloading volume fluctuation, improve sintering material moisture stable rate, improve the sinter quality.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
