Description

Technical Field

[0001] The utility model belongs to the technical field of explosive production, and in particular relates to a raw material storage device used for explosive production. Background Art

[0002] Explosives refer to substances that can burn violently in a very short period of time. They are substances that explode under the influence of certain external energy and their own energy. When explosives explode, they can release a large amount of heat energy and produce high-temperature and high-pressure gas, which can destroy, throw, and compress surrounding materials. Explosives have been increasingly widely used in mining, building blasting and demolition and other fields because of their low cost, labor saving, and the ability to work under special circumstances. The storage of explosive raw materials is very important, and the storage device needs to be lightning-proof, fire-proof and waterproof. However, in actual use, when the explosive raw material storage device discharges raw materials, the storage space is open to the outside, resulting in flow exchange between air and the air in the storage space. Water vapor in the external air enters the storage space with the air, which can easily cause the explosive raw materials in the storage space to come into contact with water vapor and become damp. The safety of the explosive raw materials after being damp is affected, making it difficult to put the damp raw materials into use, resulting in a waste of raw materials. Utility Model Content

The guide drum 3 is designed to rotate, and the guide drum 3 supports and drives a plurality of guide plates 31 to rotate. The guide drum 3 and the guide plates 31 divide the circular groove 21 into a plurality of spaces. When the storage tank body 1 is discharging, the explosive raw materials fall from the storage tank body 1 into the circular groove 21, and the raw materials are stuck between the guide drum 3 and the two guide plates 31. The guide drum 3 drives the plurality of guide plates 31 to rotate, and the guide plates 31 drive the raw materials to rotate downward, so that the explosive raw materials can be rotated to the discharge pipe 11 position for discharge, and the passage between the circular groove 21 and the storage tank body 1 is always restricted by a plurality of The two guide plates 31 are alternately blocked, so that the internal space of the storage tank body 1 is in a relatively stable state. The transfer unloading box 2 supports the vacuum fan 22, and the vacuum fan 22 extracts the air in the space of the inner groove 32. When the guide plate 31 has completed discharging the material, the blocking plate 4 is controlled to move away from the connecting hole 34, so that the blocking plate 4 no longer blocks the connecting hole 34, and the vacuum fan 22 can extract the air in the space between the two guide plates 31 through the inner groove 32 and the connecting hole 34, so that the water vapor in the space between the two guide plates 31 can be extracted, and when the two guide plates 31 are rotated to the upper side and aligned with the storage tank body 1, the internal water vapor can be extracted and reduced, so that the external air will not flow exchange and enter with the air in the storage tank body 1, thereby reducing the occurrence of the explosive raw materials in the storage tank body 1 being exposed to moisture and reducing the damage and waste of raw materials.

[0019] A plurality of blocking plates 4 are fixedly connected to one end of the guide drum 3 with a U-shaped plate 41, and the U-shaped plate 41 is slidably connected to the inner wall of the corresponding connecting hole 34. The inner wall of the circular groove 21 is fixedly connected to an extrusion convex roller 23 for extruding and pushing the plurality of U-shaped plates 41.

The guide rod 42 is slidably connected to the inner walls of the corresponding fixing rod 33. A spring 331 is fixedly connected between the fixing rod 33 and the corresponding U-shaped plate 41, and the fixing rod 33 pushes the U-shaped plate 41 through the spring 331; the connecting hole 34 uses the fixing rod 33 to support the spring 331, and the fixing rod 33 pushes the U-shaped plate 41 through the spring 331, so that when the extrusion effect of the extrusion convex roller 23 on the U-shaped plate 41 gradually disappears, the U-shaped plate 41 can drive the blocking plate 4 to continue to block the connecting hole 34.

[0021] The U-shaped plate 41 is fixedly connected to an arc rod 43 at one end, and the U-shaped plate 41 contacts the extrusion convex roller 23 through the corresponding arc rod 43.

When the guide plate 31 completes the discharge of the material, the guide drum 3 drives the U-shaped plate 41 and the blocking plate 4 to rotate to the angle of the protruding side of the extrusion convex roller 23, and then the extrusion convex roller 23 is pressed. The embossing roller 23 squeezes the U-shaped plate 41 through the arc rod 43, and the U-shaped plate 41 drives the sealing plate 4 to slide away from the material guide drum 3. At this time, the passage of the connecting hole 34 is opened, and the vacuum fan 22 is controlled to extract. The vacuum fan 22 extracts the water vapor between the two material guide plates 31 through the fixed tube 231, the air inlet 232, the inner groove 32 and the connecting hole 34. When the two material guide plates 31 are rotated to the upper side and aligned with the storage tank body 1, the internal water vapor can be extracted and reduced, so that the external air will not flow exchange and enter with the air in the storage tank body 1, thereby reducing the occurrence of the explosive raw materials in the storage tank body 1 being in contact with water vapor and getting damp, and reducing the problem of damage and waste of raw materials.
