Description

Technical Field

[0001] The utility model belongs to the technical field of explosive production, and in particular relates to a cooling device for finished emulsion explosive products. Background Art

[0002] Emulsion explosives have high density, high detonation velocity, high intensity, good water resistance, small critical diameter, good detonation sensitivity, and detonator sensitivity in the case of small diameter. The general density can be controlled to 1.05-1.25g / cm3, and the detonation velocity is 3500-5000m / s. At the same time, it has the advantages of production safety and less pollution, so the market demand and supply are relatively large. In the field of emulsion explosive production, high-temperature finished explosives are generally cooled first and then transported to the packaging workshop for packaging through a conveyor belt. There are two existing cooling methods: immersion cooling and steel belt cooling. The immersion cooling method is mainly used. However, the current immersion cooling process is to sink a section of the conveyor belt into a water tank. The result of this treatment is that if the finished emulsion explosive is to be fully cooled, either the length of the conveyor belt and the water tank needs to be lengthened, which increases the production cost and site area; or the conveying speed is reduced as much as possible, which reduces the production efficiency; both will have a negative impact on production. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a cooling device for finished emulsion explosives, which overcomes the defects in the prior art, occupies a small space and has high cooling efficiency.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A cooling device for finished emulsion explosives comprises a strip cooling water pool, in which a plurality of cooling conveyor belts are arranged in a staggered and reciprocating manner both horizontally and vertically, and the cooling conveyor belts comprise a water inlet conveyor belt, an underwater conveyor belt and a water outlet conveyor belt; the water inlet conveyor belt and the underwater conveyor belt are both provided with a longitudinal inclination from high to low along the material conveying direction, and the water outlet conveyor belt is provided with a longitudinal inclination from low to high along the material conveying direction; a plurality of anti-slip plates are evenly arranged on the water outlet conveyor belt (to prevent the finished stick explosives from sliding downward); the underwater conveyor belt comprises a first conveyor belt to a third conveyor belt or a first conveyor belt to a fifth conveyor belt.

[0006] Preferably, each conveyor belt of the cooling conveyor belt is provided with a driving device.

[0007] Preferably, baffles are provided on both sides of each conveyor belt of the cooling conveyor belt to prevent the finished explosives from sliding from both sides into the cooling water pool.

[0008] Preferably, the transversely staggered angle between the conveyor belts of the cooling conveyor belt is set to 13°.

[0009] Preferably, the longitudinal inclination angle of the water conveyor belt and the underwater conveyor belt is 6°.

[0010] Preferably, the longitudinal inclination angle of the water outlet conveyor belt is 30°.

[0011] Preferably, the starting end of each conveyor belt in the underwater conveyor belt and the starting end of the water conveyor belt are both provided with a material receiving funnel (to prevent the finished explosives from sliding into the cooling water pool).

[0012] Preferably, the cooling water pool is 26 meters long, 7.7 meters wide and 1.2 meters deep.

[0013] Preferably, the underwater conveyor belt is 24 meters long and 0.82 meters wide.

[0014] Preferably, the height of the anti-skid plate is 0.15 meters, and the spacing between adjacent anti-skid plates is 1.6 meters.

[0015] Due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0016] The utility model arranges the cooling conveyor belts to reciprocate in a staggered manner in the cooling water pool, thereby fully extending the running distance and cooling time of the finished explosive in the cooling water, and ensuring the cooling effect in a relatively small cooling space.

[0017] In conclusion, the utility model overcomes the defects in the prior art, occupies a small space and has high cooling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Embodiment 1

[0023] like Figure 1 and Figure 2As shown, the utility model is a cooling device for finished emulsion explosives, including a long strip cooling water pool 1, in which a plurality of cooling conveyor belts (not marked) are arranged in a staggered and reciprocating manner in a transverse and longitudinal direction, the cooling conveyor belts include a water inlet conveyor belt 2, an underwater conveyor belt 3 and a water outlet conveyor belt 4, the water inlet conveyor belt 2 and the underwater conveyor belt 3 are both provided with a longitudinal inclination from high to low along the material conveying direction, the water outlet conveyor belt 4 is provided with a longitudinal inclination from low to high along the material conveying direction, and a plurality of anti-slip plates 5 are evenly arranged on the water outlet conveyor belt 4; the underwater conveyor belt 3 includes a first conveyor belt, a second conveyor belt and a third conveyor belt; the starting end of each conveyor belt in the underwater conveyor belt 3 and the starting end of the water outlet conveyor belt 4 are provided with a material receiving funnel 6.

[0024] When the utility model is actually working: the cooling conveyor belt, driven by the driving device, slowly conveys the high-temperature explosive product (rod-shaped) obtained in the previous process to the cooling water in the cooling water pool 1 through the water inlet conveyor belt 2, and then slides down to the first conveyor belt, the second conveyor belt and the third conveyor belt of the underwater conveyor belt 3 which are staggered and reciprocatingly arranged for conveyance. Because the conveyance is always in the cooling water, the high-temperature explosive is fully cooled. When the explosive is fully cooled, it is conveyed to the water outlet conveyor belt 4 by the third conveyor belt, and the water outlet conveyor belt 4 conveys the finished explosive out of the cooling water pool 1 to enter the subsequent packaging and storage process.

[0025] It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
