[0002] In the automotive and machinery manufacturing industries, differential housings are critical transmission components, and their casting process is crucial to the quality and performance of the final product. Cast differential housings are typically produced using a casting process, where waste recovery and reuse is a crucial step in the production process. This waste includes defective differential housing parts.

[0003] When recycling and melting defective parts of the differential housing, a preheating structure is often not set up. Instead, the defective parts are directly put into the melting box, and the cold material directly enters the melting equipment, which often increases the temperature fluctuation and unevenness in the melting equipment, affects the quality of melting, and also increases the energy consumption in the melting box; at the same time, when the differential housing is melted, a large amount of high-temperature gas will be generated, and as the gas is discharged, a large amount of energy will often be wasted. Utility Model Content

[0004] The technical problem to be solved by the present invention is that when defective parts of a differential housing are melted and recovered, no preheating structure is provided, and the high-temperature gas discharged from the melting process easily causes a waste of energy.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] according to Figure 1-5 As shown: The utility model provides a waste recovery and melting equipment for differential case casting: it includes a melting box 1, on which an end cover 2 is provided; two mutually assembled support plates 15 are slidingly provided in the melting box 1, the space above the support plate 15 is a preheating layer 14, and the space below the support plate 15 is a melting layer 16; the melting layer 16 is connected to the preheating layer 14 through a connecting pipe 18 outside the melting box 1; a shell 12 is placed on the support plate 15; a hot air blower 4 is provided on the end cover 2, and a heating structure connected to the hot air blower 4 is provided below the end cover 2; the heating structure is inserted downward into the shell 12; an installation box 5 is fixedly provided on the outer wall of the melting box 1, and a sliding structure fixedly connected to the support plate 15 is slidingly provided in the installation box 5; a temperature monitoring device is provided on the inner wall of the preheating layer 14, and a controller 3 connected to the circuit of the temperature monitoring device is provided on the end cover 2, and the controller 3 is connected to the circuit of the hot air blower 4.

[0022] By arranging a preheating layer 14 in the melting box 1, the waste shell 12 to be melted can be preheated, thereby reducing temperature fluctuations and energy waste during the melting process and improving the melting quality. At the same time, the high-temperature hot air in the melting layer 16 can be introduced into the preheating layer 14 to heat the preheating layer 14, thereby avoiding the waste of energy caused by the direct discharge of high-temperature hot air during the melting process.

[0023] like Figure 3 As shown, the heating structure includes an air inlet pipe 10 and a heating hole 11. The air inlet pipe 10 is connected to the output end of the hot air blower 4. The air inlet pipe 10 is inserted into the housing 12, and the heating hole 11 is provided on the side wall of the air inlet pipe 10. The heating structure enables the hot air blown by the hot air blower 4 to heat the interior of the housing 12, thereby achieving an auxiliary heating effect. The temperature monitoring device includes a temperature sensor 13 disposed on the inner wall of the preheating layer 14. The temperature sensor 13 is connected to the controller 3 circuit and can monitor the temperature of the preheating layer 14 in real time and adjust the hot air blower 4 accordingly based on the monitoring results.

[0024] like Figure 5As shown, the sliding structure includes a sliding block 21 and a guide rod 23. The sliding block 21 is slidably arranged in the installation box 5. A guide groove 22 is opened on one side of the installation box 5 and communicates with the melting box 1. One end of the guide rod 23 is fixedly connected to the sliding block 21, and the other end passes through the guide groove 22 and is fixedly connected to the support plate 15. A motor 19 is set on one side of the installation box 5. The output shaft of the motor 19 is fixedly connected to a bidirectional screw 20 that is rotatably arranged in the installation box 5. There are two sliding blocks 21, and the two sliding blocks 21 are respectively threadedly connected to the corresponding positions of the bidirectional screw 20. The setting of the guide groove 22 and the guide rod 23 can limit the rotation of the sliding block 21, thereby converting the rotation of the bidirectional screw 20 into movement of the sliding block 21, and transmitting it to the support plate 15 through the guide rod 23.

[0025] A card slot 8 is provided on the melting box 1 , and a card block 9 is fixedly connected to the lower end of the end cover 2 and is inserted into the card slot 8 , thereby increasing the sealing performance between the end cover 2 and the melting box 1 .

[0026] The outer wall of the melting box 1 is provided with a sealing plate 17 fixedly connected to the support plate 15, and the outer wall of the melting box 1 is provided with an exhaust pipe 6 connected to the preheating layer 14, which can facilitate the discharge of the gas in the preheating layer 14. The bottom of the melting box 1 is provided with an outflow pipe 7 connected to the melting layer 16, which facilitates the discharge of the melted material in the melting layer 16.

[0027] Principle of the utility model

[0028] In such Figure 3 In the illustrated state, the housing 12 is placed on two support plates 15, then the end cap 2 is installed, with the block 9 engaged in the slot 8. Simultaneously, the air inlet pipe 10 is inserted into the housing 12. When the melting tank 1 is operating normally, the high-temperature hot air generated by the melting layer 16 when melting the waste material can enter the preheating layer 14 through the connecting pipe 18, thereby heating the housing 12 in the preheating layer 14 and avoiding the waste of energy caused by the direct discharge of the high-temperature hot air. Simultaneously, the hot air blower 4 can be activated, using the air inlet pipe 10 and the heating hole 11 to deliver hot air into the interior of the housing 12, heating both the inside and the outside of the housing 12, thereby achieving an auxiliary heating effect. Simultaneously, the temperature sensor 13 can monitor the temperature of the preheating layer 14 and transmit the monitoring results to the controller 3. The controller 3 controls the hot air blower 4 to adjust its operating state, thereby ensuring that the preheating layer 14 remains within the appropriate temperature range. The gas in the preheating layer 14 can be discharged through the exhaust pipe 6 and released after being treated and purified.

[0029] After the shell 12 is preheated, the motor 19 is started, so that the two sliding blocks 21 drive the support plates 15 to move away from each other. Figure 5As shown, support plate 15 no longer supports shell 12, and shell 12 falls directly into molten layer 16. The preheated scrap shell 12 enters molten layer 16 at a more uniform temperature, thereby reducing temperature fluctuations and unevenness during the melting process. This not only helps improve product quality but also reduces energy waste caused by temperature fluctuations.

[0030] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
