Description

Technical Field

[0001] This utility model relates to the field of emulsion explosive production technology, and in particular to a steel strip cooling device for emulsion explosives. Background Technology

[0002] Emulsion explosives are water-in-oil emulsion explosives that utilize emulsifiers to uniformly disperse microdroplets of an oxidizing agent salt solution in a continuous oil-phase medium containing porous materials such as dispersed air bubbles or hollow glass microspheres. Since their invention, emulsion explosives have been rapidly and widely used in industrial production due to their extremely high explosive power and impact resistance.

[0003] During the production of emulsion explosives, in order to avoid the explosive matrix temperature from getting too high, the explosive matrix is ​​usually laid on a steel belt for conveying, and coolant is sprayed onto the underside of the steel belt to cool it down, thereby reducing the temperature of the explosive matrix. However, this cooling method requires a large amount of cooling water, and the cooling water will splash during spraying, causing the coolant to be unrecoverable and wasted. At the same time, the splashed coolant can also contaminate the matrix, thus affecting the quality of the explosive. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, one objective of this invention is to provide a cooling device for emulsion explosive steel strips, in which the coolant can be reused, achieving a greater degree of water conservation compared to traditional open spraying methods.

[0005] The emulsion explosive steel strip cooling device proposed in this utility model includes a support frame and a condenser. A steel strip is arranged inside the support frame. A first cooling pipe and a second cooling pipe are respectively arranged at the top and bottom of the steel strip. A delivery pump is fixed to one end of the condenser. An input pipe is fixed to the output end of the delivery pump. The two outlets of the input pipe are respectively fixed to one end of the first cooling pipe and the second cooling pipe. An output pipe is fixed to the other end of the condenser. The two outlets of the output pipe are respectively fixed to the other end of the first cooling pipe and the second cooling pipe. Several fans are arranged at equal distances between the first cooling pipe and the second cooling pipe.

[0006] Preferably, air outlet slots are provided at the middle of both the front and rear ends of the support frame, and the first cooling pipe and the second cooling pipe are located above and below the air outlet slots.

[0007] Preferably, a fixing plate is fixed in the middle of the interior of each of the two air outlet slots, and a connecting plate for fixing the fan is fixed between the two fixing plates.

[0008] Preferably, support legs are fixed at the four bottom corners of the support frame.

[0009] Preferably, a support plate for supporting the condenser and the delivery pump is fixed to the inner side of the support leg.

[0010] The beneficial effects of this utility model are:

[0011] 1. Through a closed loop consisting of a condenser, delivery pump, inlet pipe, outlet pipe, first cooling pipe, and second cooling pipe, the coolant can be reused, achieving a greater degree of water saving compared to traditional open spraying methods. Simultaneously, the coolant flows completely within the confined pipe system, avoiding waste and pollution caused by splashing during spraying.

[0012] 2. The fan blows the cold air generated by the first and second cooling pipes onto the surface of the steel strip. At this time, the low-temperature coolant in the first and second cooling pipes and the airflow from the fan form a dual cooling mode of "liquid cooling and air cooling synergy", which significantly improves the cooling efficiency of the steel strip.

[0019] Reference Figure 1-5A cooling device for emulsion explosive steel strip includes a support frame 1 and a condenser 5. A steel strip 2 is installed inside the support frame 1. A first cooling pipe 3 and a second cooling pipe 4 are respectively installed above and below the steel strip 2. A delivery pump 6 is fixed to one end of the condenser 5, and an input pipe 7 is fixed to the output end of the delivery pump 6. The two outlets of the input pipe 7 are respectively fixed to one end of the first cooling pipe 3 and the second cooling pipe 4. An output pipe 8 is fixed to the other end of the condenser 5, and the two outlets of the output pipe 8 are respectively fixed to the other end of the first cooling pipe 3 and the second cooling pipe 4. Several fans 9 are equally spaced between the first cooling pipe 3 and the second cooling pipe 4. The first cooling pipe 3 and the second cooling pipe 4 are arranged parallel to each other on the upper and lower sides of the steel strip 2 and connected to the condenser 5 through the input pipe 7 and the output pipe 8. The cooling pipes are filled with circulating coolant. The delivery pump 6 is connected to the outlet end of the condenser 5 and pumps the cooled coolant to the input pipe 7. The input pipe 7 splits into two branches, connecting to the first cooling pipe 3 and the second cooling pipe 4 respectively. After flowing through the steel belt 2, the coolant returns to the condenser 5 through the output pipe 8 to complete the circulation. Simultaneously, as the coolant flows within the pipe, it absorbs the heat transferred from the steel belt 2. Multiple axial flow fans 9 are installed at equal intervals between the upper and lower cooling pipes and fixed to the fixing plate 11 via connecting plates 12. When the fans 9 are running, they force airflow through the air outlet slot 10, accelerating heat dissipation from the surface of the steel belt 2.

[0020] Air outlet slots 10 are provided at the middle of both the front and rear ends of the support frame 1. The first cooling pipe 3 and the second cooling pipe 4 are located above and below the air outlet slots 10 to guide the cooling airflow to be evenly distributed.

[0021] Each of the two air outlet slots 10 has a fixing plate 11 fixed in the middle, and a connecting plate 12 for fixing the fan 9 is fixed between the two fixing plates 11.

[0022] Support legs 13 are fixed at the four bottom corners of the support frame 1.

[0023] The inner side of the support leg 13 is fixed with a support plate 14 for supporting the condenser 5 and the delivery pump 6. The support plate 14 prevents the components from shifting due to vibration during equipment operation.

[0024] In operation, the emulsion explosive matrix is ​​evenly spread on the surface of the steel strip 2 and transported. At this time, the transport pump 6 is activated, and coolant is output from the condenser 5, entering the first cooling pipe 3 and the second cooling pipe 4 via the input pipe 7. As the coolant flows within the pipes, it absorbs the heat transferred from the steel strip 2. With continuous transport, the coolant returns to the condenser 5 via the output pipe 8, where it is cooled. After cooling, it re-enters the circulation loop. Simultaneously, the fan 9 is activated, blowing the cold air generated by the first cooling pipe 3 and the second cooling pipe 4 onto the surface of the steel strip 2. The low-temperature coolant in the first and second cooling pipes and the airflow from the fan 9 create a dual cooling mode of "liquid cooling and air cooling synergy," significantly improving the cooling efficiency of the steel strip 2.
