Description

Technical Field

[0001] The utility model relates to the technical field of porous ammonium nitrate storage equipment, in particular to an anti-caking silo. Background Art

[0002] At present, the most widely used mixed explosives truck in China is the on-site mixed ammonium nitrate oil explosives truck. The main raw material of this truck is porous granular ammonium nitrate. During use, the porous granular ammonium nitrate is often not used up in time or due to hot and humid weather, long transportation distance and other reasons, causing the ammonium nitrate on the top of the silo to become compacted as a whole, resulting in the porous granular ammonium nitrate being unable to fall into the production system.

[0003] At present, the commonly used method to solve the above problem is to manually crush the hardened ammonium nitrate. This method is time-consuming and labor-intensive. There is a certain safety risk when the operator stands on the roof of the vehicle to operate. The porous granular ammonium nitrate will be crushed to a certain extent after a strong impact, affecting the mixing effect of the explosives.

[0004] Another way is to install a pneumatic hammer on the outside of the porous granular nitric acid silo of the on-site mixing explosives truck, and knock on the silo at certain time intervals. This method is difficult to truly break up the already compacted porous granular ammonium nitrate. When the porous granular nitric acid is not compacted, the vibration of the pneumatic hammer will cause the internal materials to become more compact and more prone to agglomeration.

[0005] Therefore, a device with a simpler structure and the ability to be automated is needed to prevent the porous granular ammonium nitrate from agglomerating inside a mixed explosive vehicle, and an anti-caking silo is designed for this purpose. Utility Model Content

[0006] The utility model aims to solve one of the technical problems in the related art at least to a certain extent. To this end, one purpose of the utility model is to provide an anti-caking silo, which has the function of preventing agglomeration and loosening the compacted porous granular ammonium nitrate.

[0007] The anti-caking silo proposed by the utility model includes a silo body and a controller. The silo body consists of an upper silo and a lower silo. A plurality of upper stirring devices are fixedly installed in parallel between the side walls of the upper silo, and a plurality of lower stirring devices are fixedly installed in parallel between the side walls of the lower silo. An internal silo monitoring system is arranged inside the upper silo.

[0008] The upper stirring device comprises a first driving device and a first supporting device symmetrically fixed to the upper side wall of the silo, and a first stirring paddle is fixed between the first driving device and the first supporting device;

[0009] The lower stirring device comprises a second driving device and a second supporting device symmetrically fixed to the lower side wall of the silo, and a second stirring paddle is fixed between the second driving device and the second supporting device.

[0010] Preferably, a feed inlet is provided at the top of the upper part of the silo, and a discharge outlet is provided at the bottom of the lower part of the silo.

[0011] Preferably, the in-bin monitoring system includes explosion-proof cameras fixed at the four corners of the upper inner wall of the silo.

[0012] Preferably, a decoder, a power supply and a monitor are provided inside the explosion-proof camera.

[0013] Preferably, an operation indicator light, a start button, and a stop button are fixed on the surface of the controller.

[0014] The beneficial effects of the utility model are as follows: by arranging a plurality of upper stirring devices and a plurality of lower stirring devices inside the silo, when the porous granular nitric acid is loaded into the silo, the upper stirring devices and the lower stirring devices are turned on so as to evenly distribute the material and break up the small pieces of the porous granular nitric acid; during transportation and production, it can be decided whether to turn on the above-mentioned devices according to weather conditions and the like; when the above-mentioned devices are turned on when the porous granular ammonium nitrate has not yet agglomerated, a certain stirring effect can be formed inside the silo to make the material produce a certain relative movement and prevent it from agglomerating; when the porous granular ammonium nitrate is compacted, the above-mentioned devices are turned on so as to make the compacted porous granular nitric acid become relatively loose, so that it can fall to the conveying device or the discharge port at the bottom of the silo, thereby preventing agglomeration and loosening the compacted porous granular ammonium nitrate.
