[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] Figure 1 It is a structural schematic diagram of a preferred embodiment of the present invention; Figure 2 A schematic diagram of an embodiment of a shaking screen. DETAILED DESCRIPTION

[0013] The present invention is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present invention will become clearer and more specific. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0014] like Figure 1 As shown, on the one hand, this embodiment discloses an antimony smelting slag waste heat recovery device, including a quenching chamber 1 and a fan 6, wherein an antimony smelting slag feeding hopper 2 is arranged on the top of the quenching chamber, and a shaking mesh plate 3 is obliquely arranged near the top of the quenching chamber, one side of the shaking mesh plate is hinged to the side wall of the quenching chamber, and the bottom of the shaking mesh plate is connected to the side wall support of the quenching chamber through an obliquely arranged spring 7, and a material discharge gap is formed between the free end of the shaking mesh plate and the corresponding side wall of the quenching chamber; the side wall of the quenching chamber is provided with an air nozzle 4 and a warm air output duct 11, and the air nozzle is located on the lower side of the shaking mesh plate, and the air nozzle is connected to the fan through the air inlet duct 5.

[0015] On the other hand, the present embodiment discloses a method for recovering the waste heat of antimony smelting slag by using the above-mentioned antimony smelting slag waste heat recovery device. The fan is turned on to blow cold air into the wind quenching chamber through the air nozzle. At the same time, the antimony smelting slag enters the wind quenching chamber through the antimony smelting slag feeding hopper and falls on the shaking mesh plate. The elastic shaking of the shaking mesh plate causes the antimony smelting slag to be shaken and dispersed. Combined with the wind quenching effect of the cold air, the antimony smelting slag is blown away and solidified. The solidified slag falls to the bottom of the wind quenching chamber through the feeding gap, and the warm air that has recovered the waste heat of the antimony smelting slag is output through the warm air output pipe.

[0016] As a further improvement of the above technical solution, a cooling cylinder 10 is further included. The air quenching chamber is connected to the cooling cylinder through a chute 8. A valve 9 is provided on the chute. The chute is connected to the bottom of the air quenching chamber. When the valve is opened, the solidified slag flows into the cooling cylinder through the chute for further cooling.

[0017] As a further improvement to the above technical solution, Figure 2 As shown, the shaking screen includes an outer plate body 31 and an inner plate body 32 which are slidably sleeved. In this way, the overall length of the shaking screen can be adjusted by sliding, thereby adjusting the size of the feeding gap, and then adjusting the feeding rate, so as to better utilize the airflow to absorb the waste heat of the antimony smelting slag.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
