Technical Field

[0001] The utility model relates to the technical field of waste metal processing, in particular to a high-temperature calcining furnace for waste metal processing. Background Art

[0002] Scrap metal refers to metal fragments and scraps discarded by the metallurgical industry and metal processing industry, as well as metal objects scrapped during equipment renewal. It also includes metal packaging containers and scrapped vehicles recycled from urban garbage. Scrap metal is also a resource. Countries around the world have specialized units engaged in the recycling and utilization of scrap metal businesses. The recycled scrap metal is mainly used for smelting and converted into recycled metal, and some is used to produce machinery and equipment or parts, tools and civilian appliances.

[0003] At present, most scrap metals are usually heated in high-temperature calcining furnaces and then processed for repeated use. However, some scrap metals have impurities attached to their surfaces after being stored for a long time. Therefore, the impurities cannot be separated during heating, resulting in quality problems when the calcined metal is used. At the same time, some high-temperature calcining furnaces have low heating efficiency for scrap metals when using coal for heating, so this needs to be solved. Utility Model Content

[0022] The technical effect of adopting the above further solution is: by opening the second filter hole on the surface of the load-bearing plate, it is convenient to form an air duct and increase the combustion temperature of the coking coal.

[0023] Compared with the prior art, the advantages and positive effects of the utility model are:

[0024] 1. In the utility model, the user rotates the bidirectional screw on the inner wall of the heating box to drive the clamping and fixing rod on the outer surface of the bidirectional screw to move relative to each other, so as to position the scrap metal.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0034] Embodiment 1, as Figure 1-4 As shown, the utility model provides a high-temperature calcining furnace for processing scrap metals, including: a heating box 2, a protective cover 202, fixed on the outer surface of one side of the heating box 2; also including: a limit groove 201, opened on the inner wall of the heating box 2 near the protective cover 202; a bidirectional screw rod 204, threadedly embedded in the inner wall of the heating box 2, and the outer surfaces of the bidirectional screw rods 204 at opposite positions are threadedly embedded with clamping fixing rods 205; a cylinder 206, fixedly installed on the inner wall of one side of the heating box 2, and a forging block 207 is fixedly installed on the output end surface of the cylinder 206.

[0035] In this embodiment, a limiting groove 201 is provided on the inner wall of the heating box 2. When the user places the scrap metal on the surface of the load-bearing plate 105, the user rotates the bidirectional screw rod 204 on the inner wall of the heating box 2 to drive the clamping and fixing rod 205 on the outer surface of the bidirectional screw rod 204 to move relative to each other, thereby positioning the scrap metal. At the same time, the outer surface of one end of the clamping and fixing rod 205 is slidably embedded in the inner wall of the limiting groove 201, and the clamping and fixing rod 205 is limited when moving to prevent position deviation and thus failure to position the scrap metal. When the user connects the power supply of the cylinder 206 on the inner wall of the heating box 2, the cylinder 206 is started to work, driving the forging block 207 on the output end surface to move, thereby continuously forging the scrap metal while heating, thereby reducing impurities in the scrap metal and improving the quality of the processed scrap metal.

[0036] In embodiment 2, the outer surfaces of one ends of the two clamping fixing rods 205 are movably embedded in the inner wall of the limiting groove 201, a fan 203 is movably installed on the inner wall of the protective cover 202, a support barrel 1 is fixedly installed on the outer surface of the side of the heating box 2 away from the forging block 207, and an air suction hole 101 is provided on the outer surface of the support barrel 1 away from the heating box 2, a coal discharge port 102 is provided on the outer surface of one side of the support barrel 1, a coal loading plate 103 is fixedly installed on the inner wall of the support barrel 1 near the coal discharge port 102, and a plurality of filter holes 104 are provided on the surface of the coal loading plate 103, and a load-bearing plate 105 is fixedly installed on the inner wall of the support barrel 1 near one end of the heating box 2, and a plurality of filter holes 2 106 are provided on the outer surface of the load-bearing plate 105.

[0037] In this embodiment, before processing, coking coal is put in through the coal discharge port 102 and placed on the surface of the coal loading plate 103. The protective cover 202 is fixed by the heating box 2, and the fan 203 on the inner wall of the protective cover 202 is installed. When the power supply of the fan 203 is connected to start the fan 203, the fan 203 is operated to perform exhaust work. An air suction hole 101 is opened at the bottom of the support barrel 1, thereby forming an air duct in cooperation with the filter hole 104 and the filter hole 2 106, so that the coking coal heats up quickly and has a high temperature, which is convenient for processing the metal. At the same time, the smoke generated during calcination is discharged to improve the processing efficiency.

[0038] Working principle: A limiting groove 201 is provided on the inner wall of the heating box 2. When the user places the scrap metal on the surface of the load-bearing plate 105, the user rotates the bidirectional screw rod 204 on the inner wall of the heating box 2 to drive the clamping and fixing rod 205 on the outer surface of the bidirectional screw rod 204 to move relative to each other, thereby positioning the scrap metal. At the same time, the outer surface of one end of the clamping and fixing rod 205 is slidably embedded in the inner wall of the limiting groove 201 to limit the clamping and fixing rod 205 when it moves to prevent the position from being offset and thus making it impossible to position the scrap metal. When the user connects the power supply of the cylinder 206 on the inner wall of the heating box 2, the cylinder 206 is started to work, driving the forging block 207 on the output end surface to move, thereby positioning the scrap metal when it is heated. Continuous forging is performed to reduce impurities in scrap metal and improve the quality of scrap metal after processing. At the same time, the heating box 2 is supported by the support barrel 1. Before processing, coke is put in through the coal outlet 102 and placed on the surface of the coal loading plate 103. The protective cover 202 is fixed by the heating box 2, and the protective cover 202 is installed on the inner wall of the fan 203. When the fan 203 power supply is connected to start the fan 203, the fan 203 is operated to extract air. An air suction hole 101 is provided at the bottom of the support barrel 1, thereby forming an air duct with the filter hole 104 and the filter hole 2 106, so that the coke heats up quickly and the temperature is high, which is convenient for processing the metal. At the same time, the smoke generated during calcination is discharged to improve the processing efficiency.
