Specifically, a cone is fixed at the upper end of the cone cylinder, and the cone, the cone cylinder and the outlet end of the feeding pipe are concentrically arranged.

Specifically, a baffle plate with the lower end inclined towards the center direction of the cylinder body is fixed in the cylinder body above the air inlet pipe, and the outlet end of the air inlet pipe is located in a space between the baffle plate and the side wall of the cylinder body.

Specifically, the upper end of the sleeve is connected with the lower end of the conical cylinder through a telescopic sleeve, and a telescopic rod of the telescopic cylinder penetrates through the telescopic sleeve.

Specifically, the outer edge of the cylinder body is provided with a heat insulation layer.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses, simple structure, convenient operation can carry out recycle to the heat in the lead slag to heat recovery utilization rate is high, and the dress is unloaded conveniently, has practiced thrift the energy consumption greatly, has reduced workman's intensity of labour, has improved the security in work efficiency and the working process.

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

As shown in figure 1, the device for recovering the waste heat from the secondary lead smelting comprises a barrel body 1, wherein a heat-insulating layer is arranged at the outer edge of the barrel body 1, a sleeve 3 is fixed at the middle position in the lower end of the barrel body 1, a telescopic cylinder 4 is fixed in the sleeve 3, a telescopic rod of the telescopic cylinder 4 penetrates through the upper end of the sleeve 3 and then extends to the outside of the sleeve, a cone hopper 6 is fixed in the barrel body 1 above the sleeve 3, a cone barrel 7 concentric with the cone hopper 6 is arranged in the cone hopper 6, the outer edge of the cone barrel 7 is contacted with the inner edge of the lower end opening of the cone hopper 6, a plurality of through holes 13 with outlet ends facing the cone hopper 6 are formed in the side wall of the cone barrel 7, the telescopic rod of the telescopic cylinder 4 extends into the cone barrel 7 and is fixedly connected with the cone barrel, the upper end of the sleeve 3 is connected with the lower end of the cone barrel 7 through a telescopic sleeve 5, the telescopic rod of, the cone 8 sets up with the exit end of a awl section of thick bamboo 7 and inlet pipe 10 is concentric, and 1 lower extreme of barrel is fixed with rather than the discharging pipe 2 of inside intercommunication, is fixed with rather than the intake pipe 12 of inside intercommunication on the barrel 1 of awl fill 6 below, 1 internal fixation of barrel of intake pipe 12 top has the baffle 9 that the lower extreme inclines to barrel 1 central direction, and the exit end of intake pipe 12 is located the space between baffle 9 and the barrel 1 lateral wall.

The utility model discloses during the use, the lead slag of high temperature enters into in the barrel 1 through inlet pipe 10, the high temperature lead slag that falls into in the barrel 1 from inlet pipe 10 is under the guide effect of cone 8, be cyclic annular and lay in the space between awl section of thick bamboo 7 and awl fill 6, the lower extreme export that awl section of thick bamboo 7 fought 6 was fought to the awl this moment carries out the shutoff, high temperature lead slag can not fall down barrel 1 lower part, drum into the air in to barrel 1 through intake pipe 12, the air blows to high temperature lead slag through-hole 13 in the awl section of thick bamboo 7 after entering into, high temperature lead slag takes place the heat transfer with the air that blows to it, the air temperature that blows to high temperature lead slag risees and enough discharges through outlet duct 11, and carry out the exhaust-heat boiler recovery, produce steam heat supply, generate.
