Description

Technical Field

[0001] The utility model relates to the technical field of cooling furnaces, and more specifically to a cooling furnace slag discharge spiral mechanism. Background Art

[0002] Heat treatment refers to a metal hot processing technology that changes the surface or internal structure of metal materials in the solid state by means of heating, heat preservation and cooling to obtain the required properties. Among them, the cooling process mostly uses a conveyor belt to transport the metal material to a cooling furnace for cooling.

[0003] The utility model patent with patent publication number CN210035544U discloses a garbage incinerator assembly, specifically a slag discharge mechanism for a garbage incinerator. It is characterized in that it includes a rectangular cooling box, a water inlet is provided at the lower part of one end face of the cooling box, and a water outlet is provided at the upper part of the other end face. There is a conveying pipe along the cooling box. The top feed pipe of the side wall of one end of the conveying pipe near the water inlet, the upper end of the feed pipe passes through the top of the cooling box and extends outward, and the bottom discharge pipe of the side wall of one end of the conveying pipe near the water outlet, the lower end of the discharge pipe passes through the bottom of the cooling box and extends outward. There is a rotating shaft arranged along the longitudinal direction of the conveying pipe, and the two ends of the rotating shaft are respectively connected to the two ends of the cooling box in a rotating state, one end of the rotating shaft passes through the end wall of the cooling box and extends outward, and the extended end of the rotating shaft is connected to the output shaft of a motor. The rotating shaft located in the conveying pipe has spiral propulsion blades arranged continuously from one end to the other end. The slag discharge mechanism can save energy.

[0004] However, when this structure is actually used, firstly, the spiral propulsion blade adopts a one-way conveying method. When the discharge port is blocked, the waste slag is easily pushed into a dead corner at one end, which is not easy to clean. At the same time, although the water cooling method is used to cool the temperature, a large amount of water is consumed, which increases the slag discharge cost. Therefore, a cooling furnace slag discharge spiral mechanism is proposed. Utility Model Content

The waste slag enters the slag discharge bin from the slag inlet pipe 7. Under the operation of the motor 901, the first spiral conveying blade 903 and the second spiral conveying blade 904 convey the waste slag to the top of the slag discharge port 8, thereby avoiding the generation of waste slag residue at both ends inside the slag discharge box 1, and improving the efficiency and thoroughness of slag discharge. At the same time, during the rotation of the rotating rod 902, the fan blade 10 can be rotated to generate wind to enter the air delivery bin 12 from the air inlet 11, and then pass through the filter plate 13 to blow on the waste slag in transit to cool the waste slag. At the same time, after the slag discharge is completed, the dust attached to the first spiral conveying blade 903 and the second spiral conveying blade 904 can be cleaned.

[0027] As attached Figure 4 As shown, the slag discharge assembly 9 includes a motor 901 , and the motor 901 is installed on one side of the first side plate 4 .

[0028] The rotating rod 902 is inserted into the slag discharge bin, and one end of the rotating rod 902 is connected to the transmission end of the motor 901.

[0029] The first spiral conveying blade 903 is installed on the rotating rod 902.
