Description

Technical Field

[0001] This utility model relates to the technical field of cooling water circulation systems, specifically a cooling water circulation system for emulsion explosive production. Background Technology

[0002] Emulsion explosives are water-in-oil emulsion explosives that use emulsifiers to uniformly disperse droplets of an oxidizing agent salt solution in a continuous oil-phase medium containing porous materials such as dispersed air bubbles or hollow glass microspheres. In the production process of emulsion explosives, water is required in many places, such as in the preparation of the aqueous phase and the cooling of the explosive cartridge. Moreover, the water remaining after the preparation of the aqueous phase and the cooling of the explosive cartridge is eventually discarded, so the water cost is not negligible and increases the production cost.

[0003] For example, the emulsion explosive production cooling water circulation device disclosed in the authorization announcement number CN218089399U includes a water storage tank, a cooling box, an explosive roll cooling device, and an aqueous phase preparation tank. The water storage tank and the cooling box are connected by two pipelines: an inlet pipe and a return pipe. The top of the water storage tank is provided with a third water inlet, which is connected to a water injection pipe. The explosive roll cooling device is connected to the inlet pipe via a first circulation pipe, and the aqueous phase preparation tank is connected to the inlet pipe via a second circulation pipe, and the explosive roll cooling device is connected to the inlet pipe via a second circulation pipe. Although it enables the treated water temporarily stored in the water tank to be used for aqueous phase preparation and emulsion explosive cartridge cooling, and the water in the cooling tank to be filtered and cooled and then recycled, it realizes the secondary cooling and recycling of the water remaining after aqueous phase preparation and explosive cartridge cooling, thereby reducing the water cost of enterprise production and reducing the overall production cost. However, this does not solve the problem that existing cooling water circulation systems of this type are generally not conducive to convenient filtration and recycling of cold water, which affects the company's water costs, and are not convenient for flocculation and sedimentation of cooling water, nor for convenient disassembly and cleaning of filters, which affects the convenience of cleaning the cooling water circulation system and the purification effect of the cooling water circulation system.

A fourth hose 10 is installed on the end of the second filter 4 away from the third hose 9. The second filter 4 is connected to the water storage tank 1 through the fourth hose 10. When using the emulsion explosive production cooling water circulation system, the cooling water produced during emulsion explosive production is transported to the interior of the water storage tank 1. The water inside the water storage tank 1 is pumped through the first hose 5 into the interior of the hollow column 6, and then discharged into the interior of the cooling tank 2 through the hollow column 6 and the nozzle 11. The pipes of the external liquid nitrogen cooling equipment are connected to the cooling pipe 23, and cold water is circulated inside the cooling pipe 23 to cool the water inside the cooling tank 2.

When cleaning the surface of the filter plate frame 17 is required, the cooling water supply is stopped, and two sets of electric push rods 18 are activated. Supported by the filter plate frame 17, the electric push rods 18 drive the scraper 19 via the transmission rod 32, causing the scraper 19 to scrape large particles from the surface of the filter plate frame 17 to one side and discharge them through the drain port on its surface. The flocculant is then transported through the delivery pipe 7 and nozzle 11. The flocculant is brought into the cooling tank 2, where it reacts with the cooling water to purify it. The servo motor 12 is turned on, and with the support of the cooling tank 2, the servo motor 12 drives the rotating shaft 13 to rotate. With the sliding support of the roller 21 and the annular ring 15, the rotating shaft 13 drives the stirring blade 14 and the circular plate 33 to rotate. The circular plate 33 drives the stirring strip 34 to rotate, and the stirring strip 34 drives the annular ring 15 to rotate. This allows the stirring blade 14 and the stirring strip 34 to fully stir and react the cooling water and flocculant inside the cooling tank 2, realizing convenient flocculation and sedimentation of the cooling water in the cooling water circulation system and improving the purification effect of the cooling water circulation system. The top of the first filter 3 and the second filter 4 are movably mounted with top covers 25.

Finally, it is discharged back into the water storage tank 1 via the fourth hose 10 for reuse. Cooling water flows through the hollow column 6 and nozzle 11 onto the surface of the filter plate frame 17, where it filters out large particles.
