Description

Technical Field

[0001] This utility model relates to the field of waste latex explosive recycling technology, and in particular to a recycling device for waste latex explosive. Background Technology

[0002] Emulsion explosives are widely used industrial explosives and their continuous production has been achieved. However, due to improper raw materials, processes, transportation, or storage conditions, emulsion explosives may demulsify, forming waste emulsion explosives. The components of these substandard products can be recycled and reused. Physical methods typically involve heating the waste emulsion explosives to demulsify and separate the oil and water phases. In the recycling process of waste emulsion explosives, stirring is a crucial step that accelerates dissolution or dispersion and increases the reaction rate.

[0003] Chinese Patent (Application No.: CN201810208899.4) discloses a recycling device for waste emulsion explosives, comprising a frame, a mixing tank, mixing components, and a motor; the mixing tank is rotatably and horizontally mounted on the frame, the frame is provided with a fixed gear plate, the fixed gear plate is coaxially and rotatably connected to the mixing tank, and the side wall of the mixing tank is provided with a material compartment door; two or more mixing components are evenly distributed circumferentially in the inner cavity of the mixing tank, the mixing components are parallel to the axis of the mixing tank, one end of the mixing component passes through the mixing tank to the outside, and one end of the mixing component is connected to the fixed gear plate through a transmission gear; the motor is mounted on the frame, and the motor is connected to the mixing tank through a transmission component.

[0004] While the aforementioned patents can improve the mixing and homogenization effect of the matrix and sensitizer, and increase the recycling rate of emulsion explosive waste, the entire structure lacks a pressure monitoring and automatic pressure relief system. Specifically, it is impossible to monitor pressure changes inside the cylinder in real time during operation, nor can it automatically relieve pressure when it is too high. Once the pressure inside the cylinder becomes too high, it may lead to equipment rupture, leakage, or even explosion, seriously threatening the lives of operators and the integrity of the equipment. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the technical problem of this utility model is to provide a device that facilitates the recycling of waste latex explosives.

[0006] The technical solution of this utility model is as follows: a recycling device for waste latex explosives, comprising a base frame, a controller, a cylinder, a discharge valve, a top plate, a feeding frame, a stirring assembly, heating pipes, connecting pipes, a pressure gauge, an exhaust pipe, and a pressure relief assembly. The cylinder is connected to the top of the base frame, and a discharge valve is installed at the bottom of the cylinder.

The second motor is installed in the middle of the top of the top plate, the output shaft of the second motor passes through the top plate, and the stirring frame located inside the cylinder is connected to its output shaft. The second motor is electrically connected to the controller.

[0008] Furthermore, the pressure relief assembly includes a piston, a spring, a third motor, and a rotating block. The piston is slidably connected to the upper end of the connecting pipe. The top of the piston is a cover structure, and the lower end is a plug body. The plug body is in close contact with the inside of the connecting pipe and blocks the connection between the connecting pipe and the vent pipe. A spring is connected between the piston and the inside of the connecting pipe. The third motor is installed at the top of the top plate, located behind the connecting pipe. An elliptical rotating block is connected to the output shaft of the third motor. The rotating block is in contact with the cover on the top of the piston. The third motor is electrically connected to the controller.

[0009] Furthermore, it also includes scrapers, with scrapers symmetrically connected to the lower end of the mixing rack on both sides, and the scrapers are in close contact with the inner wall of the cylinder.

[0010] Furthermore, it also includes a first motor and a flip cover. The flip cover is rotatably connected to the top of the feeding frame. The first motor is installed on the top left side of the feeding frame. The output shaft of the first motor is connected to the flip cover. The first motor is electrically connected to the controller.

[0011] Furthermore, it also includes an air pump and a protective net. An air pump is installed on the right side of the top of the top plate. Both ends of the air pump are connected to pipes. The left pipe goes into the top plate and is connected to a protective net. The right pipe can be connected to an inert gas container. The air pump is electrically connected to the controller.

[0012] Beneficial effects: 1. Installing a pressure gauge on the connecting pipe will automatically activate the pressure relief system when the pressure inside the cylinder exceeds the safe range, ensuring that the internal pressure of the equipment is always within the safe range, further improving the safety of operation;

[0013] 2. An inert gas (such as nitrogen) is injected into the cylinder by an air pump to remove oxygen and reduce the risk of combustibles coming into contact with oxygen, thereby effectively preventing explosions and fires.

[0014] 3. The second motor drives the stirring rack and scraper to rotate, ensuring that the waste explosives are evenly mixed and heated in the cylinder. The scraper design can prevent the material from sticking to the inner wall, ensuring that the material is fully mixed, improving the destruction efficiency of the emulsion structure and the effect of oil-water separation.

[0020] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] Example: A device for recycling waste latex explosives, such as... Figure 1 , Figure 2 and Figure 4As shown, the assembly includes a base frame 1, a controller 101, a cylinder 2, a discharge valve 3, a top plate 4, a feeding frame 5, a stirring assembly, heating tubes 8, connecting pipes 14, a pressure gauge 15, an air outlet pipe 18, and a pressure relief assembly. The cylinder 2 is connected to the top of the base frame 1, the discharge valve 3 is installed at the bottom of the cylinder 2, the top plate 4 is connected to the top of the cylinder 2, and the feeding frame 5 is connected and communicated to the rear side of the top of the top plate 4. Multiple heating tubes for heating materials and improving reaction efficiency are installed along the circumference of the inner compartment of the cylinder 2. 8. The heating tube 8 is separated from the internal chamber of the cylinder 2. The top plate 4 is equipped with a stirring assembly. A connecting pipe 14 is connected through the top left side of the top plate 4. A pressure gauge 15 is installed on the front side of the connecting pipe 14. An exhaust pipe 18 is connected to the left side of the connecting pipe 14. The exhaust pipe 18 can be connected to an external gas purification device. A controller 101 is installed on the top front side of the top plate 4 by bolts. The heating tube 8 and the pressure gauge 15 are both electrically connected to the controller 101. A pressure relief assembly is provided on the connecting pipe 14.

[0022] like Figure 1 and Figure 2 As shown, to ensure uniform mixing of materials, the stirring assembly in this technical solution includes a second motor 9, a stirring frame 10, and a scraper 11. The second motor 9 is bolted to the middle of the top of the top plate 4. The output shaft of the second motor 9 passes through the top plate 4, and the stirring frame 10 located inside the cylinder 2 is connected to its output shaft. The second motor 9 is electrically connected to the controller 101. The scrapers 11 are symmetrically connected to the lower end of the stirring frame 10. The scrapers 11 are close to the inner wall of the cylinder 2 and can scrape off the materials adhering to the inner wall. The scrapers 11 and the stirring frame 10 rotate together to uniformly mix the materials inside the cylinder 2, thereby improving reaction efficiency and product quality.

[0023] like Figure 4 As shown, to achieve automatic pressure relief inside the cylinder 2, the pressure relief assembly in this technical solution includes a piston 16, a spring 17, a third motor 19, and a rotating block 20. The piston 16 is slidably connected to the upper end of the connecting pipe 14. The top of the piston 16 is a cover structure, and the lower end is a plug. The plug is in close contact with the inside of the connecting pipe 14 and blocks the connection between the connecting pipe 14 and the outlet pipe 18. A spring 17 is connected between the piston 16 and the inside of the connecting pipe 14. The third motor 19 is installed on the top of the top plate 4 at the rear side of the connecting pipe 14. An elliptical rotating block 20 is connected to the output shaft of the third motor 19. The rotating block 20 is in contact with the cover on the top of the piston 16. The third motor 19 is electrically connected to the controller 101. By controlling the rotation of the rotating block 20 through the third motor 19, the piston 16 is lifted, so that the gas inside the cylinder 2 can be discharged through the outlet pipe 18, thus achieving automatic pressure relief.

[0024] like Figure 1 and Figure 2As shown, it also includes a first motor 6 and a flip cover 7. The top of the feeding frame 5 is rotatably connected to the flip cover 7. The first motor 6 is installed on the top left side of the feeding frame 5 by bolts. The output shaft of the first motor 6 is connected to the flip cover 7 to ensure that the flip cover 7 tightly closes the feeding frame 5. The first motor 6 is electrically connected to the controller 101.

[0025] like Figures 1-3 As shown, it also includes an air pump 12 and a protective net 13. The air pump 12 is installed on the right side of the top of the top plate 4 by bolts. The left and right ends of the air pump 12 are connected to pipes of different lengths and shapes. The left pipe passes into the top plate 4 and is connected to the protective net 13. The right pipe can be connected to an inert gas container. The air pump 12 is electrically connected to the controller 101. The inert gas is filled into the cylinder 2 by the air pump 12, which can effectively prevent explosions and fires.

[0026] When recycling waste latex explosives, the controller 101 is first activated to start the first motor 6, which drives the flip cover 7 to rotate and open, allowing the waste explosives to be fed into the cylinder 2 through the feeding frame 5. After completion, the first motor 6 is controlled to rotate in reverse, driving the flip cover 7 to rotate in reverse and close with the feeding frame 5. Then, the heating tube 8 is activated to preheat the cylinder 2. The temperature of the cylinder 2 is gradually increased to the required value. The controller 101 is then activated to start the second motor 9. The output shaft of the second motor 9 rotates, driving the stirring frame 10 and the scraper 11 to rotate. The stirring frame 10 stirs and mixes the waste explosives while continuing to heat, ensuring that the materials are heated and mixed evenly. The scraper 11 scrapes off the materials adhering to the inner wall, continuing to stir and heat until the emulsion structure is destroyed and the oil and water phases begin to separate. Stirring ensures that the reactants are evenly distributed throughout the reaction system, increasing the reaction rate.

[0027] During the mixing process, the air pump 12 can be started. The right pipe of the air pump 12 is connected to the inert gas tank. The air pump 12 can inject inert gas into the cylinder 2 through the left pipe. The protective net 13 can filter the gas and prevent the material in the cylinder 2 from entering the pipe. Since inert gas does not support combustion, filling with inert gas (such as nitrogen) can remove the oxygen in the cylinder 2, reduce the risk of combustibles coming into contact with oxygen, and thus prevent explosions and fires.

[0028] Connecting pipe 14 is connected to cylinder 2. Pressure gauge 15 can monitor the pressure of the gas inside cylinder 2 in real time. When the pressure exceeds the safe range, the internal sensor sends a signal to controller 101. Controller 101 receives the signal and starts the third motor 19. The output shaft of the third motor 19 rotates, driving the rotating block 20 to rotate. The protrusion of the rotating block 20 pushes the piston 16 upward, compressing the spring 17. The piston 16 moves upward and no longer blocks the connection between the outlet pipe 18 and connecting pipe 14. The gas inside cylinder 2 is then discharged through connecting pipe 14 and outlet pipe 18, and then enters the gas purification device connected to outlet pipe 18. After purification, the gas is discharged, thus completing the pressure relief. After pressure relief is completed, the output shaft of the third motor 19 reverses, driving the rotating block 20 to reverse and disengage from the piston 16. The spring 17 rebounds and resets, driving the piston 16 downward to block the connection between connecting pipe 14 and outlet pipe 18.

[0029] After the oil and water are completely separated, shut down the relevant equipment and then open the discharge valve 3 to collect the separated oil and water phases for further processing or reuse.

[0030] Although this disclosure has been shown and described with reference to specific exemplary embodiments thereof, those skilled in the art will understand that various changes in form and detail may be made to this disclosure without departing from the spirit and scope of the disclosure as defined by the appended claims and their equivalents. Therefore, the scope of this disclosure should not be limited to the above embodiments, but should be defined not only by the appended claims, but also by their equivalents.
