Technical Field
[0001] This utility model relates to the field of emulsion explosive cooling and molding technology, and in particular to a rapid cooling and molding device for emulsion explosives. Background Technology
[0002] Emulsion explosives are a type of explosive material widely used in mining, civil engineering, and other fields. They are mainly composed of an oil phase (such as diesel fuel), an aqueous phase (containing ammonium nitrate solution), and an emulsifier, forming a stable emulsion through a specific process. To ensure the quality and performance of emulsion explosives, rapid cooling and molding techniques are often employed during their production.
[0003] Traditional cooling forming methods typically require significant manual labor, such as manually moving the material frames in and out of the cooling equipment. This method demands a large workforce, leading to worker fatigue from prolonged repetitive tasks and increasing labor costs. Furthermore, manual operation is prone to errors, such as inaccurate frame positioning and inconsistent cooling times, all of which affect the quality and consistency of the final product. In addition, some traditional equipment, due to design limitations, has a complex structure that occupies considerable space during transport and cooling, limiting production efficiency and flexibility. Utility Model Content

The cooling box is installed in the middle of the lower front side of the mounting plate. Semiconductor coolers are symmetrically installed on the front side of the cooling box. Two DC fans are installed on a long rod extending from the top of the cooling box, and the DC fans are aligned with the cooling box. The moving assembly is installed on the mounting plate. A material frame for storing explosive emulsion is installed on the moving assembly. Baffles are slidably sealed to both sides of the material frame. A placement plate is symmetrically connected to the front side of the mounting plate. The material frame is placed on the placement plate on the right side. The placement plate has slots on both sides corresponding to the positions of the baffles. The baffles can be lowered and opened to pass through the slots.
[0006] As a preferred embodiment of this utility model, the moving component includes a pulley assembly, a motor, a guide rail, an assembly plate, guide rods, a spring, a guide rod, and a pulley. A guide rail is provided on the lower front side wall of the assembly plate. A pulley assembly is mounted on the upper front side of the assembly plate. A motor is mounted on the upper left corner of the rear side of the assembly plate, and the motor's output shaft is connected to the pulley assembly. A guide rail is connected to the top of the assembly plate, and the assembly plate is slidably connected to the guide rail. The assembly plate is connected to the belt in the pulley assembly via a sawtooth structure. Guide rods are symmetrically slidably connected to the assembly plate. A spring is connected between each guide rod and the assembly plate. A guide rod is connected between the bottoms of the two guide rods. A material frame is connected to the guide rods. A pulley is rotatably connected to the lower end of the guide rod, and the pulley slides along the guide rail.
[0007] As a preferred technical solution of this utility model, the guide rail is V-shaped, with horizontal straight rails extending on both sides, and the V-shaped part is aligned with the position of the cooling box.

Detailed Implementation
[0020] The embodiments of this utility model will be described below with reference to the accompanying drawings.
[0021] Example: A rapid cooling and molding device for emulsion explosives, such as... Figures 1-4As shown, the device includes a cooling tank 1, a semiconductor cooler 2, a DC fan 3, a mounting plate 4, a material frame 11, a baffle 12, a placement plate 14, and a moving assembly. The cooling tank 1, used for storing coolant, is mounted in the middle of the lower front side of the mounting plate 4. Semiconductor coolers 2, used for continuously cooling the internal coolant, are symmetrically mounted on the left and right sides of the front side of the cooling tank 1. Two DC fans 3 are screwed onto a long rod extending from the top of the cooling tank 1, and the DC fans 3 are aligned with the cooling tank 1 to cool the explosive emulsion using airflow. The moving assembly is mounted on the mounting plate 4, and the material frame 11 for storing the explosive emulsion is mounted on the moving assembly. The moving component drives the material frame 11 to move, so as to solidify and cool the emulsion inside. The material frame 11 is slidably sealed with baffles 12 on both sides for easy unloading. The mounting plate 4 is symmetrically connected to the left and right sides of the front side with placement plates 14. The material frame 11 is placed on the placement plate 14 on the right side for support. The placement plate 14 has slots on both sides corresponding to the positions of the baffles 12. The baffles 12 can be opened by moving down to pass through the slots. The inner surfaces of the baffles 12 and the material frame 11 are coated with a layer of polytetrafluoroethylene coating. The polytetrafluoroethylene coating has excellent anti-stick properties and can effectively prevent the emulsion explosive from adhering to the surface.
[0022] like Figures 1-4 As shown, the moving assembly includes a pulley assembly 5, a motor 6, a guide rail 7, a mounting plate 8, a guide rod 9, a spring 91, a guide rod 10, and a pulley 101. A guide rail 41 is provided on the lower front side wall of the mounting plate 4. The guide rail 41 is V-shaped, with horizontal straight rails extending on both sides. The V-shaped portion is aligned with the cooling box 1. The pulley assembly 5 is mounted on the upper front side of the mounting plate 4. The motor 6 is mounted on the upper left rear corner of the mounting plate 4 via screws. The output shaft of the motor 6 is connected to the pulley assembly 5. The top of the mounting plate 4 is connected to... A guide rail 7 is connected, and an assembly plate 8 is slidably connected to the guide rail 7. The assembly plate 8 is connected to the belt in the pulley group 5 through a sawtooth structure. Guide rods 9 are symmetrically slidably connected to the assembly plate 8. Springs 91 are connected between the guide rods 9 and the assembly plate 8. A guide rod 10 is connected between the bottom of the two guide rods 9. The material frame 11 is connected to the guide rod 10. A pulley 101 is rotatably connected to the lower end of the guide rod 10. The pulley 101 slides along the guide rail 41 and can control the rise and fall of the guide rod 10 and the material frame 11.
[0023] When using this device, first add coolant to the cooling tank 1, then pour the prepared emulsion into the material frame 11. Next, start the motor 6, which drives the pulley assembly 5. The pulley assembly 5 causes the assembly plate 8 to move linearly at a uniform speed along the guide rail 7. The pulley assembly 5 moves the assembly plate 8 to the left, which in turn moves the guide rod 9, guide rod 10, pulley 101, and material frame 11 to the left. The pulley 101 slides along the guide rail 41. When it reaches the V-shaped part of the guide rail 41, it moves downward with the guide rail 41, thereby causing the guide rod 10, material frame 11, and guide rod 9 to descend. The spring 91 is compressed, causing the material frame 11 to enter the cooling tank 1. At this time, the motor 6 automatically stops, and the coolant in the cooling tank 1 begins to solidify and cool the emulsion in the material frame 11. At the same time, the semiconductor cooler 2 continuously cools the coolant, and the DC fan 3, which is turned on, accelerates the solidification process of the emulsion through air cooling.
[0024] After the preset cooling time is reached, motor 6 automatically restarts, driving assembly plate 8 to continue moving. Pulley 101 rises along V-shaped guide rail 41, spring 91 gradually returns to its original state, pushing guide rod 10, guide rod 9, material frame 11, and pulley 101 upwards, and continuing to move to the left until the end point. At this time, material frame 11 is supported by the left placement plate 14, and pulley group 5 stops running. The corresponding baffle 12 can be opened to remove the solidified material. Then, emulsion is added again, and the material frame 11 is brought back to the right side by pulley group 5, repeating the above cooling process. Placement plates 14 are respectively set on the left and right sides of mounting plate 4 to support material frame 11. When material frame 11 moves to the leftmost side, it is supported by the left placement plate 14; when it moves to the rightmost side, it is supported by the right placement plate 14. This allows for continuous cooling and molding of emulsion explosives, reducing the need for manual intervention.
[0025] like Figure 1 and Figure 5 As shown, it also includes a handle 121, a second spring 13, and a limiting block 15. The top of the baffle 12 is welded with a handle 121. The baffle 12 and the material frame 11 are connected with a second spring 13. The outer side of the top of the placement plate 14 is rotatably connected with a limiting block 15. The limiting block 15 contacts and cooperates with the baffle 12 to hold the baffle 12 in place.
[0026] When unloading the formed material, push the handle 121 to move the baffle 12 downwards and open it. The second spring 13 is compressed, and then the limit block 15 can be rotated to adjust its position. The limit block 15 holds the top of the baffle 12 open, preventing the second spring 13 from resetting and facilitating the unloading of material from the material frame 11. The limit blocks 15 on the two side placement plates 14 are in different positions. When the material frame 11 is on the left placement plate 14, the left baffle 12 opens; when it is on the right, the right baffle 12 opens. When closing the baffle 12, the limit block 15 resets, the second spring 13 rebounds and resets, causing the baffle 12 and handle 121 to move upwards, thus automatically closing the baffle 12.
[0027] like Figures 2-3 As shown, it also includes a guide frame 16, a movable block 17, a screw 18, and a tensioning wheel 19. The guide frame 16 is connected to the right side of the rear wall of the mounting plate 4 by screws. The movable block 17 is slidably connected to the guide frame 16. The movable block 17 passes through the front side of the mounting plate 4 and is rotatably connected to the tensioning wheel 19. The belt in the pulley assembly 5 passes around the tensioning wheel 19. The screw 18 is threadedly connected to the guide frame 16. The left end of the screw 18 is rotatably connected to the movable block 17. By rotating the screw 18, the position of the guide frame 16 can be adjusted to adjust the left and right position of the tensioning wheel 19, so that the tensioning wheel 19 loosens or tightens the belt in the pulley assembly 5, ensuring the stability of the pulley assembly 5 during operation.

Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
