[0029] Left casters 12 are provided on the slag collection box 1, a wheel bracket 6 and a push handle 53 are provided on the waste heat transfer pipe 5, right casters 61 are provided on the wheel bracket 6. The crushing group 11, the smelting furnace 3, the heating base 4, the heating gas chamber 41, and the ventilation pipe 42 are all prior arts. Some existing structures are not drawn and labeled, so there is no need to elaborate.
[0030] The waste heat pump 52 is a hot gas suction pump, which is a prior art. The waste heat transfer pipe 5 as a whole is a common heat-insulating pipe to avoid heat dissipation.
[0031] The quick-connect seat 45 and the quick connector 51 are sealed and sleeved, and the inner cavities of the vent pipe 42 and the waste heat pipe 43 are both connected to the heating air cavity 41. The quick-connect seat 45 and the quick connector 51 are a group, that is, a commonly used quick connector group for pipelines, which is the existing technology and can realize the sealed quick connection and unplugging separation of the two.
[0032] The waste heat pipe 5 is a U-shaped structure as a whole. The lower left end of the waste heat pipe 5 is connected to the inner cavity of the connecting pipe 2. When the waste heat extraction pump 52 is pumping air, the high-temperature waste heat of the slag itself is extracted and transported to the heating air cavity 41.
[0033] An air supply valve 23 is provided on the air supply pipe 22. The inner cavity of the air supply pipe 22 is connected with the inner cavity of the connecting pipe 2. When the waste heat extraction pump 52 is pumping air, external air can enter the air supply pipe 22 to achieve the air supply effect and avoid the waste heat transmission pipe 5 from being suffocated.
[0034] The sealing ring 21 is arranged at the top end of the connecting pipe 2 and is in extrusion contact with the lower end surface of the slag discharge pipe 7. The sealing ring 21 is made of vulcanized rubber, has high elastic sealing performance, is resistant to high temperature and wear, and is durable.
[0035] The outer diameter of the top section of the sealing ring 21 is not less than the outer diameter of the top section of the connecting pipe 2 and the slag discharge pipe 7, ensuring the overall extrusion sealing of the connecting pipe 2 and the slag discharge pipe 7 to avoid air leakage and slag leakage.
[0036] The pushing handle 53 is provided at the right end of the waste heat conveying pipe 5 , so that the operator can hold it and pull or push the slag collecting box 1 as a whole.
[0037] The wheel bracket 6 and the right caster 61 form a group, which are two symmetrically arranged groups in total. The left caster 12 is two symmetrically arranged, which improves the overall movement stability of the slag collecting box 1.
[0038] The right caster 61 is a universal movable wheel, and the left caster 12 is a universal brake wheel.
[0039] The connecting pipe 2 is provided with a positioning rod 24, and the slag discharge pipe 7 is provided with a limit block 71. The limit block 71 is provided with a positioning port 72 and is plugged into the positioning rod 24. When the slag collecting box 1 is moved freely to the right as a whole, it is necessary to ensure that the positioning rod 24 is aligned with the positioning port 72 and plugged into it, so as to ensure the vertical positioning effect of the sealing ring 21, the connecting pipe 2 and the slag discharge pipe 7 in the later stage.
[0040] Working mode: When the smelting furnace 3 discharges slag, open the preset valve on the slag discharge pipe 7, and at the same time open the air supply valve 23 and the connecting pipe valve 44, and start the waste heat extraction pump 52. The discharged high-temperature slag enters the connecting pipe 2 through the slag discharge pipe 7. At this time, the waste heat extraction pump 52 can extract the high-temperature waste heat of the slag itself. During the process of extracting waste heat, the outside air will enter through the air supply pipe 22 and form a high-temperature air flow with the high-temperature waste heat. The high-temperature air flow enters the heating air cavity 41 through the waste heat transmission pipe 5 and the waste heat connecting pipe 43. At the same time, the ventilation pipe 42 is externally connected to a high-temperature gas pipe with a high-temperature gas pump, which is combined with the recovered high-temperature waste heat to ensure the high-temperature smelting effect in the heating air cavity 41, and can perform high-temperature heating and smelting on the metal in the smelting furnace 3, greatly improving the recovery and utilization rate of waste heat energy during the process of collecting high-temperature slag.
[0041] In addition, the collected slag will be crushed into granular slag by the crushing group 11. When the slag collection box 1 is full, the relevant equipment and valves can be stopped. Then, quickly unplug the quick connector 51 from the quick connection seat 45 to separate it. Then loosen the brake of the left caster 12, and then hold the push handle 53 and pull it to the right, which can drive the whole slag collection box 1 to be conveniently and flexibly pulled to the right through the left caster 12 and the right caster 61. Then move the whole slag collection box 1 to the position of the slag discharge pipeline and stop. Finally, open the valve preset on the discharge pipe 13 to discharge the granular slag, realizing the flexible movement of the whole slag collection box 1 to the required position, and thus improving the convenient and flexible mobility of the whole slag collection box 1.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
