[0024] In the embodiment, as Figure 4As shown, the pool body 2 is integrally connected with the processing pool 10, and the inside of the pool body 2 and the processing pool 10 present a concave cavity, and the regions of the outer wall of the pool body 2 corresponding to the concave cavity are provided with water inlets and water outlets; first, the concave cavity structure presented between the pool body 2 and the processing pool 10 can provide the maximum area for the internal cooling medium to contact the internal emulsion explosive of the processing pool 10, and the concave cavity can allow the cooling medium to surround a larger range of the processing pool 10, so that heat can be more quickly and uniformly transferred from the emulsion explosive to the cooling medium, thereby improving the cooling efficiency and enabling heat exchange with the cooling medium, and the water inlets and water outlets are combined with external cooling equipment to realize the circulating flow of the cooling medium.
[0025] In this embodiment, as shown in Figure 4 The processing pool 10 is made of stainless steel, and the inner wall is coated with a protective layer, and the inner bottom wall of the processing pool 10 is in a slope structure, and the pool body 2, the left explosion-proof top cover 13 and the right explosion-proof top cover 14 are all made of carbon steel, and the outer walls of the pool body 2, the left explosion-proof top cover 13 and the right explosion-proof top cover 14 are all coated with explosion-proof rubber plates; the processing pool 10 is made of stainless steel, and the inner wall is coated with a protective layer, and the inner bottom wall of the processing pool 10 is in a slope structure, and the pool body 2, the left explosion-proof top cover 13 and the right explosion-proof top cover 14 are all made of carbon steel, and the outer walls of the pool body 2, the left explosion-proof top cover 13 and the right explosion-proof top cover 14 are all coated with explosion-proof rubber plates; the material of the processing pool 10 not only facilitates the rapid conduction of heat in the wall of the processing pool 10, accelerates the cooling process, but also effectively resists the erosion of the emulsion explosive to the inner wall, and the slope structure of the inner bottom wall also provides great convenience for the later cleaning, because the slope structure is beneficial to the collection and collection of sewage and impurities, and the carbon steel material of the pool body 2, the left explosion-proof top cover 13 and the right explosion-proof top cover 14 as the outermost structure provides a solid structural framework for the cooling of the processing pool 10, effectively bearing the internal pressure and possible external impact, collision and other mechanical forces, and the outer coated explosion-proof rubber plate has good elasticity and buffering performance, even in the event of an explosion, the rubber plate can absorb part of the explosion energy, reduce the damage of the explosion shock wave to the surrounding environment and personnel, and play a buffering and protection role.
[0026] In this embodiment, as shown in Figure 1 and Figure 4As shown, the bottom of the processing pool 10 is provided with a pressure sensor, and the inner wall of the processing pool 10 and the concave cavity of the pool body 2 are provided with temperature sensors, and a liquid level meter is installed in the concave cavity of the pool body 2; during the pouring of the explosive, the operator can know whether the preset filling amount is reached in time according to the pressure data, so as to accurately control the filling operation, and the liquid level meter can clearly display the liquid level height of the cooling medium in the concave cavity of the pool body 2, so as to accurately know the volume of the cooling medium, which is crucial for maintaining the normal operation of the cooling system, and the temperature sensor arranged on the inner wall of the processing pool 10 can monitor the temperature change of the emulsion explosive during the cooling process in real time, and the temperature sensor in the concave cavity of the pool body 2 is also important for monitoring the temperature of the cooling medium. By monitoring the temperature change of the cooling medium, the operator can quickly take measures to adjust, and through these data, the cooling rate and temperature distribution of the emulsion explosive can be deeply understood, so as to optimize the cooling process parameters.
[0027] In this embodiment, as shown in Figure 3 The first bevel gears 8 and the second bevel gears 9 are vertically distributed and meshed in pairs to form a group above the corresponding stirring pieces 7, and the second bevel gears 9 are coaxially connected, and the shaft heads of the stirring pieces 7 at the top penetrate the shaft centers of the first bevel gears 8 and are fixedly connected thereto, while the stirring pieces 7 constitute relative rotation between them, and the stirring pieces 7 are symmetrical about the midpoint line of the processing pool 10, and the stirring pieces 7 are composed of upper and lower groups of turbine type and anchor type paddles; the relative movement of the stirring pieces 7 in the processing pool 10 is realized by using two groups of first bevel gears 8 and second bevel gears 9, which helps to accelerate the heat transfer in the emulsion explosive, and the relative movement of the stirring pieces 7 can make the heat inside the explosive be brought to the surface more quickly, thereby improving the cooling efficiency. The turbine type paddle can quickly exchange the hot explosive at the upper part with the relatively cold explosive at the lower part, promoting uniform temperature drop of the whole, and the anchor type paddle can effectively scrape the bottom and inner wall of the processing pool 10, which is particularly important for emulsion explosives containing solid particles or components with large density, which can ensure that these components do not settle at the bottom, ensuring the uniformity and stability of the product components.
[0028] In this embodiment, as shown in Figure 5 and Figure 6As shown, the left explosion-proof top cover 13 and the right explosion-proof top cover 14 are provided with a cylindrical body with a threaded structure on the side adjacent to the reverse screw rod 11, and the left explosion-proof top cover 13 and the right explosion-proof top cover 14 are connected with the reverse screw rod 11 through the cylindrical body to form a screw transmission structure, and the left explosion-proof top cover 13 and the right explosion-proof top cover 14 are provided with a sliding groove for slidingly connecting the slide rail 12 on the other side, and the left explosion-proof top cover 13 and the right explosion-proof top cover 14 form an opening and closing structure on the top of the pool body 2. The rotation of the reverse screw rod 11 can make the left explosion-proof top cover 13 and the right explosion-proof top cover 14 close or separate under relative motion, so as to ensure the sealing property of internal cooling, prevent impurities such as dust and moisture in the external environment from entering the processing pool 10 during the cooling process, and avoid adversely affecting the quality of emulsion explosive.
[0029] In this embodiment, as shown in Figure 5 and Figure 6 , the left explosion-proof top cover 13 and the right explosion-proof top cover 14 are provided with an insertion structure on the side abutting against each other, and the left explosion-proof top cover 13 and the right explosion-proof top cover 14 are provided with a semicircular through hole penetrating through the abutting area, and the upper side of the semicircular through hole is connected with a sealing strip, and the sealing strip is wrapped on the outside of the shaft rod of the stirring member 7 on the corresponding side. When the stirring member 7 is lowered to the processing pool 10 through the assembly for lifting in the stand column 1, the left explosion-proof top cover 13 and the right explosion-proof top cover 14 are closed at the same time, and the semicircular notch forms a circular enclosure on the outside of the shaft rod of the stirring member 7, which effectively realizes the closing without affecting the stirring process, and can also ensure that the stirring member 7 maintains a vertical state during the working process. The structure of the sealing strip can effectively prevent the external air, dust and moisture from entering the inside of the processing pool 10, and the insertion structure can also make the left explosion-proof top cover 13 and the right explosion-proof top cover 14 more closely combined when closed, further increasing the sealing property of the cooling pool, and improving the safety.
