Description

Technical Field

[0001] The utility model relates to the technical field of explosive wastewater treatment, in particular to a multi-stage emulsion explosive wastewater treatment device. Background Art

[0002] Emulsion explosives refer to a type of water-in-oil gel-type water-resistant industrial explosives prepared by emulsification technology. It uses fine droplets of oxidant aqueous solution as the dispersed phase, suspended and dispersed bubbles or hollow, glass microspheres or other porous materials like oil as the continuous medium, forming a special emulsion system of water-in-oil type. In the emulsification process, charging process and packaging process and cleaning process of the preparation of emulsion explosives, a lot of wastewater will be generated, and the wastewater includes: oxidant aqueous solution components (ammonium nitrate, sodium nitrate, etc.) forming the dispersed phase, and oil phase components forming the continuous medium, mainly motor oil, vaseline, paraffin and compound wax, etc.

[0003] The patent with application number 202220997850.3 discloses a wastewater treatment device for emulsion explosive production, including a tank body, a controller and a refrigeration component. The tank body is provided with a support plate and a filter plate from top to bottom in sequence. The support plate and the filter plate divide the interior of the tank body into a wastewater chamber, a filter chamber and a water storage chamber from top to bottom in sequence. An annular refrigeration plate is embedded on the inner wall of the wastewater chamber. The refrigeration component is used to cool the annular refrigeration plate. A connecting pipe connecting the bottom of the wastewater chamber and the top of the filter chamber is provided in the tank body. A connecting valve is provided on the connecting pipe. Spherical activated carbon is provided in the filter chamber. A plurality of filter holes are vertically opened on the filter plate. A drain pipe is provided on one side of the water storage chamber.

[0004] The above technical solution utilizes a refrigeration plate to cool the wastewater, and filters the condensed oil film after cooling. Firstly, the use of refrigeration equipment consumes a large amount of electrical energy. Secondly, the activity of the mixing reaction between the wastewater and the treatment agent is reduced during cooling, resulting in low efficiency in the treatment of non-oil components in the wastewater. In addition, most traditional wastewater treatment devices use manual addition of wastewater treatment agents, and the odor generated by the treatment agent during the mixing process poses a risk of causing harm to the human body.

[0012] Furthermore, a positioning block in contact with the spring is slidably inserted in the telescopic groove, and one end of the positioning block extending out of the telescopic groove abuts against the side wall of the stirring blade.

[0013] The beneficial effects of the utility model are:

[0014] (1) The utility model provides an oil-absorbing filter cotton and a filter plate in the main body of the treatment device. The emulsion explosive wastewater is filtered by the oil-absorbing filter cotton and enters the mixing chamber. After contacting the water-soluble film in the mixing chamber, the treatment agent in the delivery box is discharged into the mixing chamber. After the motor is started, the wastewater treatment agent and the wastewater inlet water are mixed by the stirring blade. After mixing, the wastewater is pumped into the discharge chamber by the water pump, and is filtered by the filter plate in the discharge chamber and then discharged from the treatment device.

The inner wall of the through groove squeezes the positioning block to shrink into the telescopic groove until the delivery box is installed and the spring in the telescopic groove pushes the positioning block to protrude at both ends of the stirring blade, so that the delivery box is clamped and fixed on the stirring blade. After use, the positioning block is squeezed to shrink into the telescopic groove to disassemble the delivery box. After disassembly, the treatment agent and the water-soluble film are added, and the fastening frame is inserted into the fastening groove to fix the water-soluble film. This facilitates the fixed installation of the delivery box for the treatment agent before mixing, and the delivery box can be reused by replacing the water-soluble film.
