DETAILED DESCRIPTION

[0029] The preferred embodiments of the present application will be described in detail below with reference to the drawings.

[0030] Example 1

[0031] Please refer to the accompanying Figure 1 to the accompanying Figure 4The embodiment shown provides a stirring device for flammable and explosive materials, which comprises a stirring container, an uncovering mechanism 2 and a feeding and discharging mechanism. The stirring container is provided with a container body 10 for containing flammable and explosive materials, a stirring assembly arranged in the container body 10 and a cover 11 capable of sealing the opening of the container body 10. The uncovering mechanism 2 is arranged at a preset station and is capable of flexibly opening the cover 11 of the stirring container carried to the preset station. The feeding and discharging mechanism is provided with a bracket 30 arranged above the preset station, a pipeline assembly arranged on the bracket 30 and a driving mechanism capable of driving the bracket 30 and the pipeline assembly to reciprocate up and down relative to the opening of the container body 10. The pipeline assembly comprises a liquid inlet pipe 31 connected to a liquid supply source (such as a device capable of supplying RO water), a gas inlet pipe 32 connected to a gas supply source (such as a device capable of supplying compressed air) and a discharging pipe 33 connected to a next-stage reaction kettle. Control valves for controlling flow and / or pressure are respectively arranged on the liquid inlet pipe 31 and the gas inlet pipe 32.It is understood that the working principle of the stirring device in the embodiment is as follows: S1: the stirring container (processed by the previous stage) containing flammable and explosive materials is carried to the processing platform 5 at the preset work station, then the position sensor arranged on the processing platform 5 transmits the position information of the stirring container sensed by the position sensor to the controller, and after the controller determines that the position information of the stirring container is correct, the controller controls the cover opening mechanism 2 to start to flexibly open the cover 11 of the stirring container; S2: after the sensor A arranged on the gantry 4 senses that the cover 11 is opened, the controller controls the driving mechanism to start to drive the bracket 30 and the pipeline assembly to move downward together until the discharge pipe 33 is inserted into the container body 10; at this time, the outlets of the liquid inlet pipe 31 and the gas inlet pipe 32 are suspended in the opening of the container body 10 but do not contact the flammable and explosive materials; S3: when the sensor B installed on the bracket 30 senses that there is material in the container body 10, the controller controls the liquid inlet pipe 31 to inject liquid (such as RO water) into the container body 10 and controls the gas inlet pipe 32 to inject gas (such as compressed air) into the container body 10; it is explained that the injection amount of the liquid inlet pipe 31 and the injection amount of the gas inlet pipe 32 are determined according to the processing requirements, and the application does not have a limiting requirement; moreover, during the above-mentioned injection of liquid and gas, ① the controller controls the stirring assembly in the stirring container to start to stir and mix the material and the liquid; ② the controller controls the control valve to adjust the injection amount of the liquid inlet pipe 31 and the injection amount of the gas inlet pipe 32 in real time, so that the liquid inlet pipe 31 and the gas inlet pipe 32 inject liquid and gas according to the set amount; S4: after stirring and mixing for a set time, the negative pressure device in the next stage reaction kettle starts and sucks away the mixture in the container body 10 through the discharge pipe 33 (that is, the discharge pipe 33 is communicated with the negative pressure device in the next stage reaction kettle). It is explained that according to the processing requirements, the embodiment can also adopt the working mode of “stirring while sucking”. S5: after the sensor B installed on the bracket 30 senses that the material in the container body 10 is sucked clean, the gas inlet pipe 32 stops injecting gas, but the liquid inlet pipe 31 continues to inject liquid to clean the devices (such as the stirring assembly, the local discharge pipe 33, etc.) in the container body 10, and the cleaned solution is also sucked into the next stage reaction kettle; after the cleaning is completed, the driving mechanism drives the bracket 30 and the pipeline assembly to rise and reset together, the cover opening mechanism 2 cancels the force on the cover 11 to make the cover 11 flexibly close the opening of the container body 10, and the stirring container is carried away from the preset work station.

[0032] As can be seen from the above, ① the stirring device provided in this embodiment can realize processing operations such as "automatic feeding of the stirring container", "automatic and flexible opening of the lid", "automatic liquid and gas injection", "automatic stirring", and "automatic material / slurry discharge". It not only has a very high degree of automation, but also allows operators to monitor the working status of the stirring device in real time without on-site operation, thereby greatly improving processing efficiency and safety. It is well-suited for slurry preparation of flammable and explosive materials. ② In this embodiment, control valves for controlling flow and / or pressure parameters are installed on the liquid inlet pipe and the gas inlet pipe, respectively, enabling the mixing of various proportions of material and liquid, greatly expanding the applicability of the stirring device. ③ The stirring device in this embodiment has excellent connectivity with the upstream and downstream workstations, facilitating the automated continuous production and processing of flammable and explosive materials.

[0033] The following provides a detailed description of the specific structure of the stirring device for flammable and explosive materials described in this embodiment.

[0034] First, regarding the stirring container.

[0035] In the stirring container described in this embodiment, there are no restrictions on the specific structure of the container body 10. It can be a cylindrical structure with an opening on the top or a square cylindrical structure with an opening on the top, depending on the product design requirements.

[0036] The stirring assembly can be designed as follows: the stirring assembly is equipped with a stirring paddle, which is built into the container body 10, and the stirring paddle is rotatably connected to the vertical wall of the container body 10 through a bearing and bearing seat combination. Furthermore, ① to better adapt to flammable and explosive materials, the stirring paddle is made of a material that does not easily generate sparks, such as stainless steel or copper alloy; moreover, the surface of the stirring paddle needs to be smooth and burr-free, and it also needs to undergo anti-static treatment to better ensure safety during the stirring process. ② To enable the stirring paddle to be driven, one shaft end of the stirring paddle can also be designed to extend out of the container body 10 in a sealed manner.

[0037] Based on the above configuration of the stirring assembly and the overall working conditions of the stirring device, this embodiment also includes a first explosion-proof motor. The first explosion-proof motor is fixedly installed on the outer wall of the container body 10 and can drive the stirring paddle to rotate. Furthermore, to better suit flammable and explosive materials, the rotational speed of the first explosion-proof motor should not be too high to avoid generating excessive heat.

[0038] Regarding the cover 11 and its installation method, this embodiment is preferably designed as follows: Please refer to the appendix. Figure 1 Appendix Figure 3 and attached Figure 4As shown, the lid 11 includes two lid halves 110. The opposite sides of the two lid halves 110 are respectively mounted to the opposite sides of the opening on the container body 10 via a rotating structure 12 with elastic restoring force. The opposite sides of the two lid halves 110 are provided with overlapping portions 111 that can be interlocked. It can be understood that, through the rotating structure 12, both lid halves 110 have an elastic restoring function, thereby enabling them to be opened and closed flexibly; through the overlapping portions 111, the two lid halves 110 can be easily opened and closed while providing a good sealing effect on the opening on the container body 10.

[0039] Furthermore, the specific implementation structure of the rotating structure 12 is as follows: Please refer to the appendix. Figure 3 As shown, the rotating structure 12 includes a connecting part 120 and a driven part 121. One side of the connecting part 120 is fixedly connected to one side of the corresponding lid half 110, and the other side of the connecting part 120 is rotatably mounted on the side of the opening on the container body 10 via a pin and a torsion spring. One side of the driven part 121 is fixedly connected to the connecting part 120, and the driven part 121 is also rotatably connected to the outer wall of the container body 10 via a rotating shaft (understandably, the driven part 121 forms a seesaw structure). Furthermore, when the lid 11 closes the opening on the container body 10 (i.e., the attached...),... Figure 1 and attached Figure 3 (As shown in the diagram), the acted part 121 is inclined so that it can contact and cooperate with the opening mechanism 2.

[0040] Understandably, based on the above-described structural configuration of the rotating structure 12, when the opening mechanism 2 applies force to the rotating structure 12, specifically when the opening mechanism 2 applies a resisting force to the acted part 121, it can cause the connecting part 120 to rotate away from the opening on the container body 10, and the two connecting parts 120 rotate in opposite directions (to...). Figure 1 Using the indicated orientation as a reference, one of the connecting parts 120 flips to the upper right and the other flips to the upper left, thereby causing both lid halves 110 to flip away from the opening on the container body 10, and the flipping directions of the two lid halves 110 are opposite, thus opening the opening on the container body 10; when the opening mechanism 2 removes the force applied to the rotating structure 12, specifically when the opening mechanism 2 removes the force applied to the acted part 121, both lid halves 110 can elastically reset under the action of the rotating structure 12, so that the overlapping parts 111 on the two lid halves 110 overlap together, thereby closing the opening on the container body 10.

[0041] Further, based on the above structural configuration of the rotating structure 12, the present embodiment is further provided with a first lug group composed of a pair of first lugs 13 and a second lug group composed of a pair of second lugs 14 on the opposite sides of the outer wall of the container body 10, please continue to refer to the accompanying drawings Figure 3 As shown, the first lug group can be used for the rotating installation of the other side of the connecting part 120, and the second lug group is located below the first lug group and can be used for the rotating installation of the acted part 121.

[0042] Next, regarding the cover opening mechanism 2.

[0043] Based on the number of configurations of the rotating structure 12, in the present embodiment, the cover opening mechanism 2 is configured in two groups and corresponds to two rotating structures 12 one by one.

[0044] Based on the structural configuration of the rotating structure 12, in the present embodiment, the preferred implementation structure of the cover opening mechanism 2 is: please continue to refer to the accompanying drawings Figure 3 As shown, each group of the cover opening mechanism 2 is provided with a cylinder 20 and an action rod 21 fixedly connected with the piston rod of the cylinder 20, and the cylinder 20 can drive the one end of the action rod 21 to press against or separate from the acted part 121; that is, when the one end of the action rod 21 presses against the acted part 121, it can drive the acted part 121 and the connecting part 120 to overturn together; and when the one end of the action rod 21 separates from the acted part 121, the acted part 121 and the connecting part 120 are elastically reset together.

[0045] Further, the cylinder 20 preferably adopts a pen-shaped cylinder. A roller 22 is installed on the one end of the action rod 21 to reduce friction and better facilitate the action rod 21 to travel on the acted part 121 and press against the acted part 121.

[0046] In addition, a dust cover 23 is provided on the piston rod cover of the cylinder 20 to improve the safety of the cylinder 20 during operation.

[0047] Next, regarding the feeding and discharging mechanism.

[0048] In the feeding and discharging mechanism of the present embodiment, regarding the driving mechanism, the preferred implementation structure is: please continue to refer to the accompanying drawings Figure 2 As shown, the driving mechanism includes a second explosion-proof motor 34 and a lead screw module 35 connected with the power output end of the second explosion-proof motor 34, and the power output part (such as a nut) of the lead screw module 35 can move up and down and is fixedly connected with the support 30.

[0049] As to the pipeline assembly, the liquid inlet pipe 31, the gas inlet pipe 32 and the material outlet pipe 33 can be fixed to the support 30 by a cable tie.

[0050] As to the control valve, at least a throttle valve 36 and a speed regulating valve 37 can be adopted. Of course, in practical application, the above-mentioned valves are not limited.

[0051] Then, as to other structures.

[0052] The embodiment further provides a gantry 4 at the preset station, which adopts a conventional gantry structure, such as including a beam 40 and two columns 41. Based on the provision of the gantry 4, the driving mechanism is mounted on the beam 40, two groups of the cover opening mechanisms 2 are symmetrically mounted on the two columns 41, and the machining platform 5 is located below the beam 40 and between the two columns 41. Figure 1 As shown.

[0053] In addition, the embodiment further provides a carrying device, which can carry the stirring container to the machining platform 5 at the preset station. As to the specific implementation structure of the carrying device, an explosion-proof conveyor or an explosion-proof forklift can be preferably adopted.

[0054] Note: The "first", "second" and the like in the component name prefix (such as the first lug, the second lug, etc.) and the "A", "B" and the like in the component name suffix (such as sensor A, sensor B, etc.) in this specification are only for easy description and are not intended to limit the scope of the utility model patent.
