Description

Technical Field

[0001] The invention belongs to the technical field of metal recycling and reuse, and in particular relates to a recycled metal combustion chamber with high-speed air cooling and a wind cooling mechanism. Background Art

[0002] Recyclable scrap metal is also called secondary metal. The recycling of recycled metal needs to be heated and transported in the combustion chamber. The heating process inevitably requires cooling. The commonly used cooling method is water cooling. Specifically, a number of water troughs are set in the water-cooled plate. The size of each water trough is certain, and the water flow is limited. In addition, since the temperature of the recycled metal in the conveying trough is very high, the temperature of the part close to the water cooling is relatively low, and the temperature of the part far from the water cooling is very high, which makes the temperature difference between the upper and lower layers of the recycled metal in the conveying trough too large. In addition, the cooling water bends back and forth in the water trough to cool down and exchanges heat with the outer wall of the conveying trough. During the heat exchange process, if the flow rate is too small, the water will be heated to produce steam, which will gather on the top, affecting the cooling effect. It will also cause the pressure in the water trough to increase, posing a production safety hazard. Summary of the invention

[0003] In view of the deficiencies described in the above-mentioned prior art, the present invention provides a recycled metal combustion chamber and an air cooling mechanism with high-speed air cooling, which adopts high-speed air flow, and the cold air directly impacts the outer wall of the conveying trough, quickly taking away the heat and reducing the temperature difference of the recycled metal in the conveying trough.

[0004] The technical solution adopted by the present invention is:

The vibrating conveyor trough is installed on the vibrating conveyor frame and vibrates with the vibrating conveyor frame. A static air cooling mechanism is provided on the side wall of the vibrating conveyor trough and / or a dynamic air cooling mechanism is provided on the vibrating conveyor frame below the vibrating conveyor trough.

[0006] As a preferred solution of the present invention, in order to achieve more comprehensive cooling, static air cooling mechanisms are provided on both sides of the vibrating conveying trough.

Of course, other structures can also be used to form a sealing structure, and the static air cooling box still does not participate in the vibration.

[0009] As a preferred embodiment of the present invention, a flow guiding member is provided at the connection between the static air inlet chamber and the static heat exchange chamber, so that the cooling air can better blow onto various parts of the side wall of the vibrating conveying trough, improving the heat exchange efficiency.

[0010] As a preferred embodiment of the present invention, the flow guiding member is a flow guiding plate, and flow guiding holes are arranged on the flow guiding plate. Moreover, the flow guiding holes are in a trapezoidal structure, with the end towards the vibrating conveying trough being larger.

And the moving air cooling box includes a moving air inlet chamber, a moving air outlet chamber and a moving heat exchange chamber; the moving air inlet chamber and the moving air outlet chamber communicate with the moving heat exchange chamber respectively; and at least one moving air inlet is provided in the moving air inlet chamber, and at least one moving air outlet is provided in the moving air outlet chamber; the moving heat exchange chamber corresponds to the bottom wall of the vibrating conveying trough. The moving air cooling box vibrates together with the vibrating conveying frame to cool the bottom wall of the vibrating conveying trough.

[0013] As a preferred embodiment of the present invention, in order to retain the original equipment to the greatest extent and reduce modifications, the moving heat exchange chamber is composed of the bottom wall of the vibrating conveying trough, the inner wall of the vibrating conveying frame and the outer wall of the moving air inlet chamber.

[0014] As a preferred embodiment of the present invention, also in order to reduce the modification of the original equipment, the moving air inlet is located under the maintenance passage of the vibrating conveying frame and the moving air inlet communicates with the moving air inlet chamber through a pipe passing through the maintenance passage; the moving air outlet is located under the maintenance passage of the vibrating conveying frame and the moving air outlet communicates with the moving heat exchange chamber through a pipe passing through the maintenance passage and the moving air inlet chamber.

[0015] The present invention also provides an air cooling and temperature reduction mechanism, including a static air cooling box and a static temperature reduction bracket. The static temperature reduction bracket is installed outside the vibrating conveying trough, and the static air cooling box is installed on the static temperature reduction bracket.

[0016] The present invention also provides another structure of air-cooling cooling mechanism, including a dynamic air cooling box, which is placed on a vibrating conveying frame below the vibrating conveying trough, and the dynamic air cooling box includes a dynamic air inlet chamber, a dynamic air outlet chamber and a dynamic heat exchange chamber; the dynamic air inlet chamber and the dynamic air outlet chamber are respectively communicated with the dynamic heat exchange chamber; and the dynamic air inlet chamber is provided with at least one dynamic air inlet port, and the dynamic air outlet chamber is provided with at least one dynamic air outlet port; the dynamic heat exchange chamber corresponds to the bottom wall of the vibrating conveying trough; and the dynamic heat exchange chamber is composed of the bottom wall of the vibrating conveying trough, the inner wall of the vibrating conveying frame and the outer wall of the dynamic air inlet chamber.

[0017] The present invention makes as few changes as possible to the original structure of the combustion chamber. It only needs to install a static air cooling cooling mechanism on the side wall of the vibrating conveying trough. The static air cooling cooling mechanism does not participate in the vibration. A dynamic air cooling cooling mechanism is installed on the vibrating conveying frame on the bottom wall of the vibrating conveying trough. The dynamic air cooling cooling mechanism participates in the vibration. Both the static air cooling mechanism and the dynamic air cooling mechanism use high-speed air cooling to directly cool the vibrating conveying trough. The cold air directly impacts the outer wall of the conveying trough, quickly takes away the heat, and reduces the temperature difference of the recycled metal in the conveying trough.
