Description

Technical Field

[0001] The utility model relates to the technical field of emulsion explosives, in particular to an emulsion explosive sensitization device. Background Technique

[0002] Emulsification is a process in which a liquid is uniformly dispersed in another immiscible liquid in the form of extremely tiny droplets. Commonly, the oil phase is dispersed into the water phase. Oil and water form two layers in a container. If an appropriate surfactant, i.e., an emulsifier, is added and strongly stirred, the oil is dispersed into tiny droplets and dissolved in water to form an emulsion. During the production process of emulsion explosives, after the oil phase and water phase materials are heated to a certain temperature respectively, they are stirred and mixed in a certain proportion to produce emulsification. After the colloidal matrix formed by emulsification is mixed with a foaming agent or a solid sensitizer for sensitization, emulsion explosives are formed. Sensitization is divided into physical sensitization and chemical sensitization. Physical sensitization refers to adding bubbles carried by porous substances to adjust the density of emulsion explosives and improve their initiation sensitivity; chemical sensitization is to use the gas generated by chemical reactions to be uniformly dispersed in the explosive in the form of tiny bubbles to achieve a foaming effect.

[0003] After retrieval, a disclosed emulsion explosive sensitization device with the publication number CN213895658U, in which an installation cavity and a mixing cavity are provided in the tank body, and the mixing cavity is located below the installation cavity; the feed inlet of the feed pipe is arranged on the upper end face of the tank body, and the feed inlet of the feed pipe is respectively communicated with the latex matrix feed inlet and the sensitizer liquid inlet. The discharge port of the feed pipe is arranged on the upper end face of the cavity of the mixing cavity; the middle part of the feed pipe is arranged obliquely downward and a spiral blade mechanism coaxial with the feed pipe is further arranged inside the middle part of the feed pipe; a stirring mechanism is arranged in the mixing cavity, and the stirring mechanism includes a motor and stirring blades. The spiral directions of the spiral ribbon stirring blades and the threaded stirring blades are opposite, forming an up-and-down convection circulation stirring, which can accelerate the stirring efficiency.

[0004] However, the above-mentioned scheme does not have an emulsion explosive cooling and anti-static structure. Since the initiation sensitivity of emulsion explosives is relatively high, during the sensitization process of emulsion explosives, the continuous operation of the stirring structure may generate heat and static electricity due to friction, resulting in potential safety hazards of explosion during the sensitization process of emulsion explosives.

[0005] Therefore, an emulsion explosive sensitization device is proposed, which has the advantages of emulsion cooling, anti-static and high safety, so as to solve the problems in the above-mentioned background technique. Content of the Utility Model

[0007] To achieve the above object, the utility model adopts the following technical solutions: An emulsion explosive sensitization device includes a tank body.

The left side of the top surface of the tank body is communicated with a feed pipe, and a motor is fixedly connected to the right side of the upper part of the tank body. A transmission belt is wound and connected between the output end of the motor and the top end of the stirring shaft. Heat conduction plates are embedded and installed on both the left and right sides of the tank body, and water tanks are covered on the separated surfaces of the two heat conduction plates. A number of extension columns are evenly arranged on the facing surfaces of the two heat conduction plates. A heat exchange pipe is installed inside the water tank, and both ends of the heat exchange pipe extend to the outside of the water tank and are connected to an external cooling fan. A water seal ring is arranged on the top surface of the tank body corresponding to the stirring shaft, an aqueous solution is filled in the water seal ring, and a grounding wire is inserted through the side surface of the water seal ring.

[0010] As a further description of the above technical solution: The heat conduction plate is integrally in a circular arc structure, and a number of the extension columns are arranged on the concave surface of the heat conduction plate.

Furthermore, the heat conducting plate and several convex columns on its surface conduct the heat generated during the emulsified explosive sensitization stirring stage into the aqueous solution in the water tank, so that the heat generated during the emulsified explosive stirring stage can be discharged and cooled in a timely manner. At this time, by arranging a water seal ring at the connection between the stirring shaft and the tank body, when static electricity is generated by the rotation and friction of the stirring shaft, the grounding wire arranged inside the water seal ring can timely conduct the static electricity in the tank body into the ground. Combining with the motor driving the transmission belt to be connected with the stirring shaft for transmission, the anti-static of the tank body is realized. Compared with the prior art, cooling and anti-static can be carried out during the emulsified explosive sensitization stirring stage, thereby avoiding potential safety hazards caused by continuous temperature rise and static electricity accumulation of the emulsified explosive in the tank body.

The cooling structure of the present device can also cope with other forms of heating and cooling of the tank body 1. For example, in the case where the tank body 1 is heated by sunlight during transportation. The control method of the motor 3 in the present utility model is to control by manually starting and closing the switch. The wiring diagram of the power element and the power supply are common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control method and wiring layout of the present utility model will not be explained in detail. In order to increase the heat exchange efficiency of the heat exchange tube 10, the heat exchange tube 10 is arranged in a serpentine structure;

[0023] In one embodiment, a shunt hopper 17 is arranged below the feed pipe 2, and the shunt hopper 17 is obliquely welded to the inner wall surface of the tank body 1. Several V-shaped stoppers 18 are equidistantly arranged on the inner side surface of the port at the right end of the shunt hopper 17. Through the arrangement of the shunt hopper 17 and several V-shaped stoppers 18, when the sensitizing agent is injected into the tank body 1, the inclined shunt hopper 17 guides the sensitizing agent to several V-shaped stoppers 18, and the sensitizing agent is shunted by several V-shaped stoppers 18, increasing the dispersion degree of the sensitizing agent and being beneficial to rapid fusion.

[0024] In one embodiment, a first temperature sensor 15 is arranged on the inner wall surface of the tank body 1, and a second temperature sensor 16 is arranged on the inner wall surface of the water tank 9. Both the first temperature sensor 15 and the second temperature sensor 16 are electrically connected to an external display panel.

[0025] In one embodiment, the heat conduction plate 11 is integrally in a circular arc structure, and several extension columns 12 are arranged on the concave surface of the heat conduction plate 11. Through the arrangement of several extension columns 12, the contact area between the heat conduction plate 11 and the emulsion explosive in the tank body 1 is increased, achieving the purpose of rapid cooling.

[0026] In one embodiment, a plurality of stirring frames 7 are arranged around the axis line of the stirring shaft 5, and a plurality of through holes are provided on the inner sides of the stirring frames 7.

[0028] Working principle:

[0029] When in use, first inject the sensitizing agent into the tank body 1 through the feed pipe 2, and then start the motor 3, so that the output end of the motor 3 drives the stirring shaft 5 to rotate through the transmission belt 4, so that the plurality of stirring frames 7 and stirring columns 8 with through holes on the stirring shaft 5 stir the emulsion explosive until the emulsion explosive and the sensitizing agent are fully mixed. When cooling and anti-static, first inject water into the water seal ring 6 to make the liquid level closely attached to the water level pointer 13. Through the water level pointer 13, it can be observed whether the installation area of the stirring shaft 5 of the tank body 1 leaks air. By connecting the heat exchange pipe 10 built in the water tank 9 with an external cold air blower, the cold air continuously passes through the heat exchange pipe 10 and transfers the cold quantity to the aqueous solution in the water tank 9. Furthermore, the heat conduction plate 11 and a plurality of convex columns on its surface conduct the heat generated in the emulsion explosive sensitizing and stirring stage into the aqueous solution in the water tank 9, so that the heat generated in the emulsion explosive stirring stage can be discharged and cooled in time. At this time, by setting the water seal ring 6 at the connection between the stirring shaft 5 and the tank body 1, when static electricity is generated by the rotation and friction of the stirring shaft 5, the ground wire 14 arranged on the inner side of the water seal ring 6 can timely conduct the static electricity in the tank body 1 to the ground, realizing the anti-static of the tank body 1.
