Description

Technical Field

[0001] This application relates to the field of inclined chute technology, and more specifically, to a material conveying inclined chute. Background Technology

[0002] In a side-blown furnace for molten pool smelting, raw materials undergo a series of chemical reactions to form a melt containing metallic elements and compounds. These melts typically contain high-value metals, but may also contain impurities and harmful substances. To further improve the purity of the metals and recover valuable metals, the melt needs to be transported to the next side-blown furnace for further processing.

[0003] Because of the high temperature of the molten material, the working environment temperature will rise, posing a safety hazard of burns to workers. It will also cause heat loss. In addition, the existing inclined chutes are mostly fixed with a large number of bolts during assembly, which increases the difficulty of disassembly and assembly and makes it inconvenient to clean the inside of the inclined chutes regularly. Utility Model Content

[0004] The purpose of this application is to provide a material conveying chute that cools the molten material during the conveying process, recovers and utilizes waste heat, reduces heat loss, and facilitates regular cleaning of the chute's interior.

[0005] This application provides a material conveying chute, which adopts the following technical solution:

[0006] A material conveying chute includes a chute body and a cover. Support blocks are respectively provided on the outer walls of both ends of the chute body. A heat exchange tube is provided at the upper end of the support block and abuts against the outer wall of the chute body. A first groove is provided at the upper end of the chute body. A first protrusion is provided at the lower end of the cover. The first protrusion cooperates with the first groove. An exhaust pipe is provided at the upper end of the cover. Baffles are respectively provided at both ends of the cover. A closed space is formed between the baffles, the chute body and the support blocks. The heat exchange tube is located in the closed space and its end protrudes through the baffle.

[0007] Preferably, the support block is provided with a plurality of second grooves, and the stop block is provided with a plurality of second protrusions, the second protrusions being disposed within the second grooves.

[0013] Preferably, the outer wall of the inclined groove body is provided with a groove, and the heat exchange tube is disposed in the groove.

[0014] Preferably, the material conveying chute further includes a flexible heat insulation layer, which is wound around the outside of the chute body and the cover.

[0015] Compared with the prior art, the beneficial effects of this application are as follows:

[0016] This application involves setting heat exchange tubes on the outside of the inclined chute body. During the process of the molten material flowing inside the inclined chute body, heat exchange occurs between the molten material and the heat exchange medium inside the heat exchange tubes. This reduces the temperature of the molten material while simultaneously recovering and utilizing the waste heat of the molten material, thereby reducing heat loss.

[0017] By installing an exhaust pipe, the flue gas inside the inclined chute is extracted by an external fan, making it easier to centrally treat the flue gas.

[0018] By setting a first protrusion and a first groove, when the cover is installed on the inclined groove body, the first protrusion enters the first groove, and the cover and the inclined groove body are fixed together by the first protrusion and the first groove, thereby reducing the use of bolts, improving the efficiency of disassembly and assembly of the cover, and facilitating the regular cleaning of the inside of the inclined groove body.

[0034] Example

[0035] like Figure 1-6 As shown in the embodiment of this application, the material conveying chute includes a chute body 1 and a cover 2. Support blocks 3 are respectively provided on the outer walls of both ends of the chute body 1. A heat exchange pipe 4 is provided on the upper end of the support block 3. The heat exchange pipe 4 abuts against the outer wall of the chute body 1. A first groove 5 is provided on the upper end of the chute body 1. A first protrusion 6 is provided on the lower end of the cover 2. The first protrusion 6 works in conjunction with the first groove 5. An exhaust pipe 7 is provided on the upper end of the cover 2. In specific implementation, there are two exhaust pipes 7. One exhaust pipe 7 is located at the inlet end of the melt and the other exhaust pipe 7 is located at the outlet pipe of the melt. The two exhaust pipes 7 are connected to the main pipe 18. Baffles 8 are respectively provided on both ends of the cover 2. A closed space 9 is formed between the baffles 8, the chute body 1 and the support block 3. The heat exchange pipe 4 is located in the closed space 9 and the end of the heat exchange pipe 4 passes through the baffles 8.

[0036] In use, the high-temperature molten material inside the side-blown furnace of the molten pool is discharged into the interior of the inclined trough body 1, and the heat exchange medium is introduced into the interior of the heat exchange tube 4. Under its own gravity, the molten material flows downward along the inclined trough body 1. During the process of the molten material flowing inside the inclined trough body 1, heat exchange occurs between the molten material and the heat exchange medium inside the heat exchange tube 4, thereby reducing the temperature of the molten material and realizing the recovery and utilization of the waste heat of the molten material, reducing the loss of heat energy.

[0037] The external fan extracts the flue gas from inside the inclined chute body 1, making it easier to treat the flue gas in a concentrated manner.

[0038] When installing the heat exchange tube 4, the heat exchange tube 4 is placed on the support block 3, and then the cover 2 is installed on the inclined groove body 1. At this time, the first protrusion 6 enters the first groove 5, and a closed space 9 is formed between the baffle 8, the inclined groove body 1 and the support block 3. The heat exchange tube 4 is located in the closed space 9 and is fixed between the baffle 8, the inclined groove body 1 and the support block 3, thereby reducing the use of bolts and improving work efficiency. Since the use of bolts is reduced, the disassembly and assembly efficiency of the cover 2 can be improved, which makes it easier to clean the inside of the inclined groove body 1 regularly.

[0039] In this embodiment, the support block 3 is provided with a plurality of second grooves 10, and the stop block 8 is provided with a plurality of second protrusions 11. The second protrusions 11 are disposed in the second grooves 10. The arrangement of the second grooves 10 and the second protrusions 11 can improve the stability of the connection between the support block 3 and the stop block 8, while reducing the use of bolts and improving work efficiency.

[0040] In this embodiment, a support frame 12 is provided on the outer wall of the cover 2, and a cylinder 13 is provided on the support frame 12. A baffle 14 is provided on the inner side of the cover 2, and a connecting rod 15 is provided on the baffle 14. The upper end of the connecting rod 15 extends through the cover 2 and the support frame 12, and a moving plate 16 is provided on the upper end of the connecting rod 15. The cylinder 13 drives the moving plate 16 to move closer to or away from the cover 2.

[0041] During use, when the side-blowing furnace cannot accommodate more molten material, the cylinder 13 drives the moving plate 16 to move closer to the cover 2. The moving plate 16 drives the connecting rod 15 to move, and the connecting rod 15 pushes the baffle 14 into the interior of the inclined chute body 1. The baffle 14 blocks the molten material and controls the side-blowing furnace to stop discharging the molten material.

[0042] In this embodiment, there are two connecting rods 15, and the cylinder 13 is located between the two connecting rods 15. The two connecting rods 15 are used to improve the smoothness of the operation of the moving plate 16.

[0043] In this embodiment, the upper end of the cover 2 is an arched structure.

[0044] In this embodiment, the heat exchange tube 4 has a serpentine structure. The serpentine structure of the heat exchange tube 4 can increase the contact area with the inclined groove body 1 and improve the heat exchange effect.

[0045] In this embodiment, multiple heat exchange tubes 4 are provided. Multiple heat exchange tubes 4 can realize segmented heat exchange of the melt, improve the cooling effect of the melt, and when one heat exchange tube 4 is damaged and needs to be replaced, the other heat exchange tubes 4 can still be used normally, ensuring the normal operation of heat exchange.

[0046] In this embodiment, a groove 17 is provided on the outer wall of the inclined groove body 1, and the heat exchange tube 4 is disposed in the groove 17. The groove 17 can increase the contact area between the heat exchange tube 4 and the inclined groove body 1, thereby improving the heat exchange effect.

[0047] In this embodiment, in order to reduce heat loss, a flexible heat insulation layer (not shown in the figure) is wrapped around the outside of the inclined chute body 1 and the cover 2. The flexible heat insulation layer is fixed by a component that is easy to disassemble, such as a rope, so as to avoid the use of bolts. The flexible heat insulation layer can further improve the stability of the connection between the cover 2 and the inclined chute body 1.

[0048] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
