Recycling device for zinc smelting discharge port of electric heating rotary kiln

Abstract

The recovery device comprises a recovery tank, an adjusting mechanism is fixedly installed at the top of the recovery tank, heat insulation shells are arranged on the outer walls of the two sides of the recovery tank correspondingly, heating pumps are arranged in the heat insulation shells, and two first circulating pipes are fixedly installed on the outer wall of the same side of the recovery tank; the two first circulating pipes are in one-to-one correspondence with the two heating pumps, liquid pumping ports of the heating pumps are communicated with the first circulating pipes, liquid outlets of the heating pumps are provided with second circulating pipes, and one side of the recovery tank is fixedly provided with a fixed side chamber. Through cooperative arrangement of a first rotating pipe, a first stirring pipe, a second rotating pipe and a second stirring pipe, zinc liquid in the recycling tank can be continuously stirred, the situation that the zinc liquid precipitates in the recycling tank is prevented, through cooperative arrangement of a first circulating pipe, a heating pump, a second circulating pipe, a connecting pipe and a flow dividing pipe, the zinc liquid can be recycled, and the recycling efficiency is improved. And continuous cyclic heating treatment can be carried out on the zinc liquid in the recovery tank, and the heating state of the zinc liquid in the recovery tank is kept.

Description

technical field [0001] The invention relates to the technical field of an electric heating rotary kiln, in particular to a recovery device for a zinc smelting outlet of an electric heating rotary kiln. Background technique [0002] Electrothermal rotary kiln zinc smelting is a relatively common zinc smelting technology nowadays. After the zinc smelting is completed, the zinc liquid needs to be recovered through a recovery device. The existing recovery devices are such as figure 1 As shown, the recovery pipe needs to be aligned with the discharge port of the electrothermal rotary kiln for zinc smelting. However, the recovery pipe cannot be adjusted, and it cannot meet the needs of zinc liquid recovery for different electrothermal rotary kiln zinc smelting discharge ports. When the zinc liquid is recovered from the zinc discharge port, the connection between the recovery pipe and the discharge port is not stable. When the discharge of zinc liquid is large, it is easy to leak d...

Problems solved by technology

[0003] The purpose of the present invention is to provide a recovery device for the discharge port of the electrothermal rotary kiln for zinc smelting, and to solve the following technical problems: (1) The recovery pipe of the recovery device for electrothermal rotary kiln zinc smelting in the prior art is not easy to adjust, and cannot meet the needs of different electric heating systems. The technical problem of recovering zinc liquid from the zinc smelting outlet of the rotary kiln; (2) Solve the problem that the recovery pipe and the connection position of the outlet are not connected properly when the recycling device in the prior art recovers the zinc liquid from the zinc smelting outlet of the electric heating rotary kiln Stable, and the technical problem of liquid leakage due to sloshing is easy to occur when the liquid zinc discharge is large; (3) Solve the problem that the recovery device in the prior art cannot guarantee the overall state of the zinc liquid after collecting the zinc liquid, resulting in a rapid drop in the temperature of the zinc liquid and precipitation technical issues
