Description

Technical Field

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

[0002] Most industrial explosives are of the emulsion explosive type. Industrial explosives, also known as civilian explosives, are explosive mixtures composed mainly of oxidants and combustibles and formed according to the principle of oxygen balance. They are non-ideal explosives.

[0003] Industrial explosives are characterized by low cost, simple manufacturing and reliable application, and are therefore widely used in coal mining, metallurgy, petroleum geology, transportation, hydropower, forestry and construction, metal processing and controlled blasting. During the emulsification process of emulsion explosives, the explosion effect of the explosive components is easily reduced due to the high emulsification temperature of the liquid. Therefore, during the emulsification process, a rapid cooling device is used to assist in heat dissipation of the emulsion explosive matrix to avoid affecting the explosion effect of the explosive components and facilitate the subsequent rapid molding of the emulsion explosive matrix, thereby improving the processing efficiency of the emulsion explosives.

[0004] Chinese patent announcement number CN219792851U discloses a rapid cooling and molding device for emulsion explosive matrix, which relates to the technical field of emulsion explosive processing, including a main body component, a cooling box is arranged at the rear of the main body component, and a turning device is arranged at the middle of the front end of the main body component, and a medium circulation mechanism is arranged on the side of the turning device close to the cooling box, and the turning device includes a motor box, and a driving motor is arranged inside the motor box. The utility model has a reasonable structure. By starting the driving motor, the driving motor drives the first rotating block, the second rotating block and the special-shaped turning frame to rotate, so as to turn the emulsion explosive matrix and dissipate heat. Since the special-shaped turning frame occupies a large area as a whole, the contact surface with the emulsion explosive matrix is ​​large. At the same time, the hollow section frame is evenly distributed on the surface of the special-shaped turning frame, and the cooling and heat dissipation is relatively uniform. The cooperation between the hollow section frame and the special-shaped turning frame improves the cooling and heat dissipation efficiency of the emulsion explosive matrix and shortens the cooling time of the emulsion explosive matrix.

[0005] However, the above-mentioned patent dissipates heat by turning the material, and adopts a special-shaped turning rack with a large contact area with the emulsion explosive matrix, and then circulates the cooling medium through the hollow section rack arranged on the turning rack. However, arranging the turning rack in a hollow shape not only increases the difficulty of processing, but also reduces the rigidity of the turning rack, because the turning rack is subjected to alternating stimulation of cold and heat, which can easily cause damage to the turning rack. For this reason, the turning strength of the turning rack must be reduced, but this will inevitably affect the cooling efficiency. Utility Model Content

[0006] The utility model provides a device for rapidly cooling an emulsion explosive matrix, which can cool the emulsion explosive matrix without affecting the working strength of a material tipping rack, thereby rapidly and efficiently completing the cooling work of the emulsion explosive matrix.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] Embodiment 1:

[0048] like Figures 1 to 4 As shown, a device for rapidly cooling an emulsion explosive matrix provided in this embodiment comprises: a cooling tank 1 for storing the emulsion explosive matrix, the cooling tank 1 comprising: a feed port 101 arranged at the upper end of the cooling tank 1 for discharging materials, a discharge port 102 arranged at the bottom of the cooling tank 1 for discharging materials, and valves arranged in the feed port 101 and the discharge port 102 for controlling the flow of materials, and the cooling tank 1 is made of a metal material with good thermal conductivity so as to better dissipate heat.

[0049] In order to cool down the cooling tank 1 more quickly, a cooling device and an auxiliary heat dissipation mechanism are arranged on the cooling tank 1 to continuously cool down the cooling tank.

[0050] Among them, the cooling device includes a storage box 2 arranged on one side of the cooling tank 1 for containing coolant, and a cooling pipe connected to the storage box 2 for cooling the cooling tank 1. The material of the cooling pipe is a metal material with good thermal conductivity. A circulating water pump 3 is arranged in the storage box 2 for inputting the coolant into the cooling pipe for cooling circulation. The cooling medium in the storage box 2 is circulated through the cooling pipe by the circulating water pump 3, thereby cooling the internal temperature of the cooling tank 1.

[0051] The cooling pipe includes an outer cooling pipe 4 spirally arranged on the outer surface of the cooling tank 1 and an inner cooling pipe 401 penetrating the cooling tank 1 and communicating with the outer cooling pipe 4. The outer cooling pipe 4 cools the shell of the cooling tank 1, and the inner cooling pipe 401 cools the interior of the cooling tank 1 and transports the cooling medium in the outer cooling pipe 4 to the storage box 2 to complete the circulation of the cooling medium. The smaller the pitch of the outer cooling pipe 4, the larger the contact area between the outer cooling pipe 4 and the outer shell of the cooling tank 1, and the better the cooling effect.

[0052] The auxiliary heat dissipation mechanism is arranged on the cooling device to cool it, and the auxiliary heat dissipation mechanism includes a heat dissipation fan 5 arranged on one side of the storage box 2 , and the storage box 2 is cooled by the heat dissipation fan 5 .

The spiral conveying roller 1 7 and the spiral conveying roller 2 8 are arranged on both sides of the stirring shaft 6. The longer the length of the paddle 601 is, the better the stirring effect is. At the same time, it should be noted that the spiral conveying roller 1 7 and the spiral conveying roller 2 8 should not be touched.

[0058] The conveying directions of the spiral conveying roller 1 7 and the spiral conveying roller 2 8 are opposite, so as to control the flow of materials in the cooling tank 1 and accelerate the heat dissipation of the materials.

The arrangement of the transition wheel 13 enables the driving wheel 10 to drive the driven wheel 2 12 to rotate. Through the arrangement of the transition wheel 13, the driving rotation direction can be changed, so that the rotation directions of the driven wheel 11 and the driven wheel 2 12 are opposite, and then the rotation directions of the spiral conveying roller 17 and the spiral conveying roller 28 are opposite, so that the synchronous and eccentric rotation effect is achieved when in use, thereby controlling the spiral conveying roller 17 and the spiral conveying roller 28 to accelerate the flow of materials and fully dissipate the heat of the materials.

[0063] Working principle: When in use, the valve of the feed port 101 is opened, the emulsion explosive matrix is ​​put in from the feed port 101, and then the double-headed motor 9 is started, which synchronously drives the cooling fan 5 and the stirring shaft 6 to rotate, the stirring shaft 6 drives the paddle 601 to rotate, the double-headed motor 9 drives the driving wheel 10 to rotate, the driving wheel 10 drives the driven wheel 11 and the transition wheel 13 to rotate, and the transition wheel 13 drives the driven wheel 12 to rotate, thereby synchronously starting the stirring mechanism, the turning mechanism and the auxiliary heat dissipation mechanism to work, and at the same time starting the circulating water pump 3, the water pump 3 transports the cooling medium in the storage box 2 to the external cooling pipe 4 and then transports it back to the storage box 2 through the internal cooling pipe 401, forming a cycle.
