Description

Technical Field

[0001] This utility model relates to the field of emulsion explosive processing technology, specifically to an emulsion explosive cooling device. Background Technology

[0002] Emulsion explosives generally refer to a class of water-in-oil emulsion industrial explosives prepared using emulsification technology. This involves uniformly dispersing microdroplets of an aqueous solution of oxidizing agents into a continuous oil-phase medium containing porous materials such as dispersed air bubbles or hollow glass microspheres, forming a water-in-oil emulsion. Emulsion explosives are a type of water-containing explosive. After being filled and molded, emulsion explosives require cooling and hardening, thus necessitating the use of cooling equipment.

[0003] Currently, the existing technology for cooling emulsion explosives generally uses cooling pools or circulating sprays. However, in this cooling method, after the water in the cooling pool or the water in the circulating spray exchange heat with the emulsion explosive, the water temperature gradually rises, resulting in poor subsequent cooling effect on the emulsion explosive. Therefore, it is essential to design an emulsion explosive cooling device to solve this problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cooling device for emulsion explosives, which solves the problem that existing devices for cooling emulsion explosives are generally cooling pools or circulating sprays, and the water temperature gradually rises after heat exchange with the emulsion explosives.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an emulsion explosive cooling device, including a cooling box, a pair of first vertical plates are fixedly connected to the outer walls of both sides of the cooling box, a conveyor roller is rotatably connected between adjacent first vertical plates, the left and right conveyor rollers are rotatably connected by a conveyor belt, and the outer wall of the conveyor belt is clearance-fitted with the inner wall of the opening of the cooling box, and a cooling mechanism and a connecting mechanism are respectively installed at the top and inside of the cooling box;

[0006] The cooling mechanism includes a water pump fixedly connected to the top of the cooling box, and the inlet and outlet of the water pump are respectively connected to a first pipe and a second pipe. The outer walls of the first pipe and the second pipe away from the water pump are both fixedly connected to the interior of the cooling box. A spray assembly is installed below the second pipe. A heat dissipation aluminum fin is provided in the middle of the first pipe, and the heat dissipation aluminum fin is connected to the cooling box by bolts. A cooling fan is connected to the front end face of the heat dissipation aluminum fin by bolts.

[0007] Preferably, the spray assembly includes a third pipe connected to the second pipe, and the two ends of the third pipe are fixedly connected to second vertical plates. The outer wall of the second vertical plate is fixedly connected to the inner wall of the cooling box, and the bottom end of the third pipe is connected to a plurality of spray heads.

The output shaft of the first motor is connected to the stirring rod via a coupling.

[0009] Preferably, a second motor is fixedly connected to the side wall of the cooling box.

[0012] Beneficial effects

[0013] This utility model provides a cooling device for emulsion explosives, which has the following beneficial effects:

[0014] The filled and cooled emulsion explosives can be placed on a conveyor belt. Then, the second motor is started, driving the first pulley to rotate. This, in turn, drives the second pulley via a belt. The second pulley, in conjunction with the conveyor rollers, moves the conveyor belt to transport the emulsion explosives. Simultaneously, a water pump and cooling fan are activated. The water pump draws water from the bottom of the cooling tank through the first pipe, then discharges it through the second pipe into the third pipe, and finally sprays it out through spray nozzles to cool the passing emulsion explosives. The serpentine cavity flow channels inside the heat sink fins allow the water in the first pipe to conduct heat outwards as it passes through, providing initial cooling. Then, the first motor is started again, driving a stirring rod to rotate. This agitates the water in the cooling tank, providing secondary cooling and ensuring effective cooling of the emulsion explosives. Attached Figure Description

[0024] In this embodiment, the spray assembly includes a third pipe 8 that is connected to the second pipe 7, and the two ends of the third pipe 8 are fixedly connected to a second vertical plate 9. The outer wall of the second vertical plate 9 is fixedly connected to the inner wall of the cooling box 1, and the bottom end of the third pipe 8 is connected to a plurality of spray heads 10.

[0025] In this embodiment, the connecting mechanism includes a stirring rod 13 that is rotatably connected to the inside of the cooling box 1 via a bearing. A pair of horizontal plates 14 are fixedly connected to the lower side wall of the cooling box 1. A third vertical plate 15 is fixedly connected between the pair of horizontal plates 14.

[0031] It is worth noting that all standard parts used in this utility model can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings.

The models of electrical structure equipment involved can be selected according to the user's needs, as long as they meet the requirements of this application.

[0032] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0033] Example: When this device is needed, the external power supply and control circuits of each electrical component can be connected. Then, the filled and cooled emulsion explosive is placed on conveyor belt 4. The second motor 17 is then started, causing it to drive the first pulley 18 to rotate. The first pulley 18, through belt 20, drives the second pulley 19 to rotate.

Simultaneously, the water pump 5 and cooling fan 12 are started. The water pump 5 draws water from the bottom of the cooling tank 1 through the first pipe 6, and then through the second... Pipe 7 drains into the third pipe 8, and finally sprays out through the spray head 10 to spray and cool the emulsion explosive passing below. At the same time, because there is a serpentine cavity flow channel inside the heat dissipation aluminum fin 11, when the water in the first pipe 6 passes through the heat dissipation aluminum fin 11, the heat in the water can be conducted outward with the help of the cooling fan 12, thus initially cooling the water. Then, the first motor 16 is started, which drives the stirring rod 13 to rotate. In this way, the stirring rod 13 can stir the water in the cooling tank 1, thus cooling the water a second time, thereby ensuring the cooling effect on the emulsion explosive in the later stage.
