Description

Technical Field

[0001] This utility model relates to the field of emulsion explosives technology, and in particular to an emulsion explosives mixing and stirring device. Background Technology

[0002] When producing emulsion explosives, especially in large batches, traditional emulsion explosive mixing equipment has limited capacity and may require multiple mixing operations to complete the production of that batch. Each mixing operation may introduce errors in raw material ratios or operational procedures, resulting in differences in the properties of the emulsion explosives produced in the same batch. These differences may pose a danger during blasting operations, which needs to be addressed. Therefore, an emulsion explosive mixing and stirring device was designed. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to provide a mixing and stirring device for emulsion explosives, which can centrally mix and stir emulsion explosives that have already been produced, ensuring uniform explosive properties and guaranteeing that emulsion explosives produced in the same batch have the same explosive properties.

[0004] The emulsion explosive mixing and stirring device proposed according to this utility model includes a frame and a support frame. A moving mechanism is provided on the surface of the frame, and a stirring mechanism is provided at the bottom of the moving mechanism. A mixing box is fixed inside the support frame, and a mixing chamber and a heat preservation chamber are provided inside the mixing box.

[0005] The stirring mechanism includes a mounting plate, on the upper surface of which two drive motors are fixed. The output end of the second drive motor passes through the mounting plate and extends to the bottom of the mounting plate. A stirring rod is fixed to the output end of the second drive motor.

[0006] The top of the stirring rod is fixed with a flange that is fixed to the output end of the second drive motor, the bottom of the stirring rod is fixed with a scraper blade and a guide blade, and the surface of the stirring rod is fixed with a bearing and a stirring blade.

[0007] Preferably, the moving mechanism includes a first drive motor fixed to the side wall of the frame and a lead screw movably installed inside the frame. One end of the lead screw is fixed to the output end of the drive motor. A lead screw nut is movably installed on the surface of the lead screw. A connecting plate is fixed to the lower surface of the lead screw nut. A housing is fixed to the lower surface of the connecting plate. Telescopic cylinders are symmetrically fixed to the side walls of the housing.

[0008] Preferably, the moving end of the telescopic cylinder is fixed to the upper surface of the mounting plate and symmetrically arranged on both sides of the second drive motor.

[0009] Preferably, reinforcing rings are symmetrically fixed to the lower surface of the mounting plate, and the reinforcing rings are fitted onto the outside of the bearing.

[0010] Preferably, a gate is movably installed at one end of the mixing box, and a guide plate is fixed on the side wall of the mixing box below the gate.

[0011] Preferably, the bottom of the mixing box is fixed with a flow guide joint that is symmetrically installed at the position of the insulation cavity.

[0012] The beneficial effects of this utility model are: the emulsion explosives that have already been produced can be mixed and stirred again to ensure uniform properties and that the properties of emulsion explosives produced in the same batch are the same. After the blasting design, when taking emulsion explosives from the same batch, the properties of the same batch are the same, so that they can be taken in a safe and quantitative manner, thus achieving high-precision and safe blasting operations.

[0018] Reference Figure 1-4 An emulsion explosive mixing and stirring device includes a frame 1 and a support frame 2. A moving mechanism 3 is provided on the surface of the frame 1, and a stirring mechanism 4 is provided at the bottom of the moving mechanism 3. A mixing box 5 is fixed inside the support frame 2, and a mixing chamber 51 and a heat preservation chamber 52 are provided inside the mixing box 5.

[0019] The stirring mechanism 4 includes a mounting plate 41. Two drive motors are fixed on the upper surface of the mounting plate 41. The output end of the second drive motor 42 passes through the mounting plate 41 and extends to the bottom of the mounting plate 41. A stirring rod 43 is fixed to the output end of the second drive motor 42.

[0020] The top of the stirring rod 43 is fixed with a flange 431 that is fixed to the output end of the second drive motor 42. The bottom of the stirring rod 43 is fixed with a scraper blade 432 and a guide blade 433. The surface of the stirring rod 43 is fixed with a bearing 434 and a stirring blade 435. In this embodiment, a total of two scraper blades 432 and four guide blades 433 are provided. The six blades are arranged in a circular array with an included angle of 60 degrees between the blades. The scraper blades 432 are axially symmetrically arranged. Each guide blade 433 is inclined and forms a 30-degree angle with the plane. It is used to guide the emulsion explosive to flow upward. The emulsion explosive flowing upward is broken up by the stirring blades 435 and remixed. During stirring, the scraper blades 432 scrape and separate the emulsion explosive adhering to the inner wall or bottom of the mixing chamber 51. The guide blades 433 guide the flow of the separated emulsion explosive. Finally, the stirring blades 435 break up and remix the emulsion explosive.

[0021] The moving mechanism 3 includes a first drive motor 31 fixed to the side wall of the frame 1 and a lead screw 32 movably installed inside the frame 1. One end of the lead screw 32 is fixed to the output end of the drive motor. A lead screw nut 33 is movably installed on the surface of the lead screw 32. A connecting plate 34 is fixed to the lower surface of the lead screw nut 33. A housing 35 is fixed to the lower surface of the connecting plate 34. Telescopic cylinders 36 are symmetrically fixed to the side wall of the housing 35. The first drive motor 31 drives the lead screw 32 to rotate. The rotation of the lead screw 32 drives the lead screw nut 33 to move horizontally, thereby driving the housing 35 to move horizontally. Since the bottom of the telescopic cylinder 36 is fixed to the mounting plate 41 of the stirring mechanism 4, and the telescopic cylinder 36 is fixed to the housing 35, the stirring mechanism 4 moves synchronously when the housing 35 moves horizontally. Activating the telescopic cylinder 36 can drive the stirring mechanism 4 to move up and down as a whole.

[0022] The moving end of the telescopic cylinder 36 is fixed to the upper surface of the mounting plate 41 and symmetrically arranged on both sides of the second drive motor 42.

[0023] A reinforcing ring 6 is symmetrically fixed on the lower surface of the mounting plate 41. The reinforcing ring 6 is fitted on the outside of the bearing 434. The installation of the reinforcing ring 6 improves the structural reduction and prevents the stirring rod 43 from breaking when it rotates at high speed.

[0024] A gate 53 is movably installed at one end of the mixing box 5, and a guide plate 54 is fixed on the side wall of the mixing box 5 below the gate 53.

[0025] A flow guide joint 55 is fixed at the bottom of the mixing box 5 and symmetrically installed at the position of the insulation cavity 52. ​​The flow guide joint 55 can be connected to a pipe to circulate hot water in the insulation cavity 52 to achieve the insulation function.

[0026] In addition to the above structure, it also includes a terminal controller, which is signal-connected to the moving mechanism 3 and the stirring mechanism 4.

[0027] When using this device, firstly, all the finished emulsion explosives are put into the mixing chamber 51 of the mixing box 5. Then, the moving mechanism 3 is started, which drives the stirring mechanism 4 to move horizontally and vertically. The spatial position of the stirring rod 43 is adjusted, and the second drive motor 42 is started to drive the stirring rod 43 to rotate at high speed, mixing and stirring the emulsion explosives in the mixing chamber 51 to achieve uniform explosive properties. After the centralized mixing is completed, a sample is taken and retained, and an ignition experiment is conducted. The experimental data is recorded, and the experimental data of the sample is recorded in the data of the batch of emulsion explosives produced, which is convenient for calculating the amount of explosives in subsequent blasting design and for carrying out high-precision and safe blasting operations.
