Description

Technical Field

[0001] The utility model relates to the technical field of emulsion explosive production, in particular to an emulsifier adding device for emulsion explosive production. Background Art

[0002] Emulsion explosives generally refer to a type of industrial explosive prepared by emulsification technology, in which droplets of aqueous solution of oxidant salts are uniformly dispersed in an oil phase continuous medium containing porous materials such as dispersed bubbles or hollow glass microspheres, forming an oil-in-water type latex-like aqueous explosive. Emulsion explosives are a type of aqueous explosive. Emulsion explosives have high density, high detonation velocity, high intensity, good water resistance, small critical diameter, good initiation sensitivity, and detonator sensitivity in the case of small diameter. They usually do not use pyrotechnics as sensitizers, are safe to produce, and cause less pollution.

[0003] During the production process of existing emulsion explosives, emulsifiers need to be added to them. When the emulsifier is added to the raw materials for producing emulsion explosives, it is usually only added on top. During subsequent stirring, the raw materials below cannot be evenly mixed with it. At the same time, when adding the emulsifier, it is usually added all at once, which also makes it difficult to fully mix the subsequent emulsifier and the raw materials. Utility Model Content

[0010] Preferably, a limit plate is rotatably mounted on the rotating rod, and the limit plate is mounted on one side of the emulsifier tank.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) By setting up the fixed pipe, the discharge pipe and the motor, the motor and the solenoid valve are started, and the emulsifier in the emulsifier tank flows into the discharge pipe along the fixed pipe, and flows to each discharge branch pipe through the discharge pipe, and flows from the discharge branch pipe to each position of the raw material in the mixing tank. At the same time, the motor rotates to drive the discharge pipe and the discharge branch pipe to rotate, so that the raw material and the emulsifier can be fully mixed while the emulsifier is sent to each position in the mixing tank, thereby avoiding the problem of uneven mixing caused by the emulsifier being only added above the raw material;

[0016] (2) By setting the circular hole, rotating rod and driven wheel and other structures, when the motor rotates to drive the discharge main pipe and the discharge branch pipe to rotate for stirring, the rotating rod is driven to rotate, and the rotation of the rotating rod drives the connecting rod and the turntable to rotate.

[0031] like Figure 3 and Figure 4 As shown, based on Example 1 and Example 2, in order to prevent the emulsifier from being added into the mixing tank all at once, an intermittent mechanism is provided in the emulsifier tank 3.

[0032] The intermittent mechanism includes a connecting rod 8, which is rotatably mounted on the emulsifier tank 3. A turntable 81 is mounted on the bottom of the connecting rod 8, which is rotatably mounted on the bottom inner wall of the emulsifier tank 3. A round hole 82 is formed on the turntable 81, which is matched with the discharge hole 16.

When the circular hole 82 rotates to coincide with the discharge hole 16, the emulsifier in the emulsifier box 3 will flow into the mixing tank 1 through the fixed pipe 5 and the discharge main pipe 6 for uniform stirring. When the circular hole 82 rotates to not coincide with the discharge hole 16, the discharge hole 16 will be blocked, so that the emulsifier stops flowing out, thereby preventing the emulsifier from being added to the mixing tank 1 all at once, and adding in batches can leave enough time so that the emulsifier and the raw materials can be further fully mixed.
