The utility model provides a steam heating bin pretreatment device suitable for semi-solid hazardous waste, which comprises a steam generator, a steam output pipe, a steam chamber, an SMP mixing bin and a steam loop pipe, one end of the steam output pipe is connected with the steam generator, the other end of the steam output pipe is connected with the steam chamber, the steam chamber is positioned between the inner wall of the SMP mixing bin and a stirring shaft of the SMP mixing bin, and the steam loop pipe is connected with the steam chamber. The steam output pipe is arranged in the steam chamber and is arranged on the inner wall of the SMP mixing bin, one end of the steam loop pipe is connected with the steam chamber, the other end of the steam loop pipe is connected with the steam generator, the steam output pipe electric control valve is arranged on the steam output pipe, and the loop pipe electric control valve is arranged on the steam loop pipe. According to the device, through combination of steam heating and mechanical stirring, the problem that the semi-solid hazardous waste cannot be stirred and mixed uniformly due to high-temperature melting or low-temperature solidification in the pretreatment stage can be effectively solved, so that efficient pretreatment of the semi-solid hazardous waste with high temperature sensitivity is achieved, and the fluidity and uniformity of the semi-solid hazardous waste are improved.

This utility model discloses a positive pressure smelting industrial electric furnace, relating to the field of smelting equipment technology. The utility model includes a furnace body and a furnace cover. A flue gas treatment component is provided on one side of the top of the furnace cover, and a feeding component is provided on the other side of the top of the furnace cover. The flue gas treatment component includes a combustion cylinder located on one side above the furnace cover. An overflow pipe is fixedly connected to the bottom of the combustion cylinder, and the bottom end of the overflow pipe extends to the upper inner side of the furnace body. This utility model introduces carbon monoxide from the furnace body into the combustion cylinder for combustion through the overflow pipe on the combustion cylinder. The heat generated by the combustion is used to heat the water in the sleeve through heat exchange fins, solving the problem of difficulty in recovering and reusing the waste heat generated by carbon monoxide combustion in existing systems. Simultaneously, the threaded rod in the mounting frame drives the collar and the feeding pipe to rise and fall, ensuring that the discharge end of the feeding pipe is always above the molten pool inside the furnace body, solving the problem of difficulty in preventing some powder from clogging the furnace flue during the feeding process.

The utility model relates to crushing and briquetting integrated processing equipment, which belongs to the technical field of automation equipment and comprises a briquetting component, a crushing component which is communicated with the briquetting component and fixedly connected with the briquetting component through bolts is arranged at the upper end of the briquetting component, and a discharge chute communicated with the briquetting component is arranged on one side edge of the lower portion of the briquetting component. The briquetting assembly comprises a briquetting machine box communicated with the smashing assembly, and a material receiving opening is formed between the briquetting machine box and the smashing assembly. The smashing assembly comprises a smashing box body, and a plurality of cutter head rollers which are connected with the smashing box body in an inserted mode in a bearing mode and operate in an extrusion mode are arranged in the smashing box body. The device has the characteristics of compact structure, high treatment capacity, energy conservation, consumption reduction and good operation stability. The problem of resource cyclic utilization is solved. The pollution emission is reduced; meanwhile, the resource value increment is realized.
