[0007] By adopting the above technical solution, the insert box is pulled out, and then the finished casting is placed in the insert box. After that, it is inserted back into the finished product chamber, and then the billet is put into the billet chamber. Then the residual heat produced by the casting in the insert box enters the billet chamber through the hot air vent and acts on the billet in the billet chamber. The high-temperature finished casting is isolated and the residual heat is volatilized, which realizes the recovery and utilization of residual heat and reduces safety hazards.

[0030] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a device for preheating scrap steel using the residual heat of castings.

[0031] Example 1:

[0032] Combination Figure 1-4 As shown, the present invention provides a device for preheating scrap steel using the waste heat of castings, including a waste heat mechanism 100, a speed-up mechanism 200 and a separation mechanism 300. The waste heat mechanism 100 includes a finished product chamber 110, a hot air vent 120 opened at the top of the finished product chamber 110, and a blank chamber 130 connected and communicating with the finished product chamber 110.

[0033] Speed-up mechanism 200, the speed-up mechanism 200 includes a box 210 connected and communicating with the finished product chamber 110, and a fan 220 connected and communicating with the box 210;

[0034] The separating mechanism 300 includes a U-shaped plate 310 installed inside the blank chamber 130 and a filter plate 320 connected to the U-shaped plate 310.

[0035] Furthermore, the U-shaped plate 310 is placed horizontally, and the hot air vent 120 is located outside the U-shaped plate 310. With this layout design, the U-shaped plate 310 can divide the blank in the blank chamber 130 into upper and lower layers, making it easier for the blank to receive residual heat.

[0036] Furthermore, a baffle 500 is installed on the top of the U-shaped plate 310. The baffle 500 is inclined and can prevent the blank from falling into the finished product chamber 110 from the hot air vent 120.

[0037] Furthermore, a cover plate 600 is movably installed on one side wall of the blank chamber 130. The cover plate 600 facilitates the operation of putting blanks into and taking out blanks from the blank chamber 130.

[0038] Example 2:

[0039] Combination Figure 1-2As shown, based on Embodiment 1, a slot is provided on one side of the blank chamber 130, and the box body 210 is located inside the slot. The slot provides installation space for the box body 210.

[0040] Furthermore, the box body 210 is made of metal material, and its top is connected to the top of the slot cavity. The box body 210 made of metal material can firmly support the blank chamber 130, and at the same time it also increases the connection between the finished product chamber 110 and the blank chamber 130.

[0041] Example 3:

[0042] Combination Figure 1 As shown, in the above embodiment, a box 400 is inserted into one side of the finished product chamber 110. The bottom of the box 400 fits against the bottom of the inner cavity of the finished product chamber 110. The box 400 can prevent the castings in the finished product chamber 110 from being scattered and facilitate the operator to take out the finished castings in a unified manner.

[0043] The working principle and usage process of this utility model are as follows: When this device is put into actual use, pull out the insertion box 400, fill the insertion box 400 with finished castings, then insert it back into the finished product chamber 110, then open the baffle 500, and fill the top and bottom of the U-shaped plate 310 with billets. Then, the residual heat from the castings produced in the insertion box 400 enters the billet chamber 130 through the hot air inlet 120, and then acts on the billets in the billet chamber 130. During this process, the fan 220 is started, and the air generated by the fan 220 flows into the finished product chamber 110, accelerating the flow of the residual heat in the finished product chamber 110 into the billet chamber 130. Then, the hot air flows between the billets separated by the U-shaped plate 310 and the filter plate 320. The billets are wrapped by the hot air, which improves the drying efficiency of the billets. The high-temperature finished castings are isolated and the residual heat is volatilized, which realizes the recovery and utilization of residual heat and reduces safety hazards.
