Description

Technical Field

[0001] The invention belongs to the field of dangerous agent mixing for explosives, and in particular relates to a self-positioning and self-cleaning device for mixing explosives. Background Art

[0002] The preparation of existing pyrotechnics in China requires that the pyrotechnics be fully soaked in a special paint and then mixed evenly for subsequent pyrotechnic dipping operations. The key quality of the pyrotechnics mixing process is to mix the pyrotechnics evenly and finely without precipitation, agglomeration, or bubbles.

[0003] Because the explosives used in pyrotechnics are detonators or ignition powders, their high energy and high sensitivity make the safety risks of their preparation process extremely high. During the mixing process of pyrotechnics, there is dry agent in the mixing process, or there is friction between the mixing tooling and the mixing container, there is a great risk of explosion.

[0004] Based on this, most of the current domestic production operations are to mix the medicines manually behind the chest guard. During the mixing process, the medicines in the medicine cups are stirred continuously in multiple directions with mixing rods to prevent the medicines from agglomerating and uneven mixing. After the mixing is completed, the mixing tools are immediately cleaned with a cleaning solvent to prevent the medicines stuck on the mixing tools from changing from a wet state to a dry state, which poses a safety risk.

[0005] Therefore, it is necessary to design a self-cleaning device for mixing explosives, which can not only realize the automatic mixing of explosives, but also realize the self-cleaning of mixing tools. It can completely eliminate the risk of manual contact with dry explosives, improve the inherent safety of the production process, and ensure that the explosives are mixed evenly and finely to meet the process quality requirements. It can solve the problems of high safety risks, high labor intensity and low degree of automation in the preparation of explosives. Summary of the invention

It should be understood that the embodiments are only used to illustrate the technical effects of the present invention, rather than to limit the protection scope of the present invention.

[0025] The invention discloses a self-defined self-cleaning device for mixing explosive agents, comprising a workbench, an agent mixing mechanism, a self-aligning mechanism and a self-cleaning mechanism, wherein the agent mixing mechanism, the self-aligning mechanism and the self-cleaning mechanism are arranged on the left and right sides of the workbench.

[0026] like Figure 1As shown, the medicine mixing mechanism is used to mix the medicine in the medicine cup to reduce the risk of direct contact between humans and medicines. It includes a medicine dispensing cylinder 108, and a liquid level buffer 105 with adjustable height is set at one end of the left side of the medicine dispensing cylinder 108, which can not only achieve smooth movement of the medicine dispensing cylinder 108 in place, but also adjust the cylinder stroke by adjusting the height of the liquid level buffer 105; a C-shaped mounting frame 111 is set on the sliding end of the medicine dispensing cylinder 108, which is connected to the medicine dispensing cylinder 108 by bolts. Coaxial mounting holes are provided at both the upper and lower ends of the C-shaped mounting frame 111, and a pneumatic motor 109 is provided at the upper end thereof, and the working end of the pneumatic motor 109 is connected to one end of the dispensing connecting rod 107 through a coupling; a long strip mounting hole is provided on the bottom end of the dispensing connecting rod 107, and the mixing tooling 103 is inserted into the long strip mounting hole and fastened by a set screw; a bearing support 106 with a flange plate is provided on the upper surface of the lower end of the C-shaped mounting frame 111, and the dispensing connecting rod 107 passes through the inner hole of the bearing support 106; a guide sleeve 104 is provided on the lower surface of the lower end of the C-shaped mounting frame 111, and the C-shaped mounting frame 111 is fixedly connected to the upper surface of the guide sleeve 104 by bolts, and the internal structure of the guide sleeve 104 is a trumpet structure shape, and the closing end of the trumpet structure cooperates with the outer ring of the bearing support 106, and with the help of the bearing support 106, it is ensured that the guide sleeve 104 and the dispensing connecting rod 107 are coaxial.

[0027] like Figure 2 In the medicine mixing mechanism, three groups of pressing blocks 113 are evenly distributed on the edge of the guide sleeve 104, and the upper end of each group of pressing blocks 113 carries a buffer spring 112. In this way, after the medicine mixing is completed, the medicine dispensing cylinder 108 drives the mixing tool 103 to lift up, but with the elastic force of the spring, the pressing block 113 of the guide sleeve 104 continues to apply a pressing force to the medicine, preventing the medicine cup from being lifted up by the mixing tool 103 due to the viscosity of the medicine and falling off.

[0028] like Figure 1 As shown, the medicine mixing mechanism and the self-aligning mechanism are both arranged on the bracket 1, the self-aligning mechanism is arranged at the lower end of the medicine mixing mechanism, and the self-aligning mechanism includes a medicine cup lifting cylinder 101; the extended end of the medicine cup lifting cylinder 101 is provided with a medicine cup lifting support plate 102. The use of this upper and lower distribution layout can ensure that the medicine cup and the mixing tool 103 are precisely coaxial, avoiding the risk of explosion caused by the mixing tool 103 contacting the edge of the medicine cup during the mixing process.

[0029] like Figure 1As shown, the medicine mixing mechanism includes a mixing tool 103, on which a group of vertically distributed mixing blades are arranged, each blade is an inclined structure, which ensures that the medicine can be driven to flip up and down during the mixing process, and ensures that the medicine is mixed evenly.

The cleaning tank 205 can be quickly hung therein through the limit pin 203. During the working process, the cleaning solvent is filled in the cleaning tank 205 through the solvent replenishing device for cleaning the mixing tool 103.

[0031] The self-cleaning mechanism is provided with a solvent replenishing device at its upper end, which includes a spray gun 202 and a syringe 201. The syringe 201 is filled with a cleaning solvent. During operation, the cleaning tank 205 is filled with the cleaning solvent through the solvent replenishing device, which can not only be used to replenish the solvent in the cleaning tank 205, but also to flush the agent on the edge of the cleaning tank arm.

[0032] like Figure 1 As shown, the self-cleaning medicine mixing mechanism, before each medicine mixing, the mixing tool 103 is immersed in the cleaning tank 205.

At the same time, the self-cleaning mechanism quantitatively sprays a part of the cleaning solvent into the cleaning tank 205, which not only supplements the volatile solvent in the cleaning tank 205, but also can flush the medicine at the edge of the cleaning tank 205 arm. After the mixing is completed, all cylinders return to their original positions, and then the material receiving cylinder 206 drives the cleaning tank 205 to extend, and the dispensing cylinder 111 drives the mixing tool 103 to fall, and the mixing tool 103 is immersed in the cleaning tank 205. At the same time, the pneumatic motor 109 is forward and reversed to clean the mixing tool 103.
