Technical Field

[0001] This utility model relates to the field of metal smelting waste slag recycling technology, specifically a dust prevention device for metal smelting waste slag recycling. Background Technology

[0002] Nickel-iron alloy slag is a waste slag generated during the smelting of stainless steel. The nickel-iron alloy extracted from nickel-iron slag (which does not contain active metals such as potassium and sodium) can ensure that the environment is not polluted, and the useful metal components can be selected. The traditional nickel-iron alloy recycling processes are rod milling, sorting and dehydration.

[0003] However, existing metal smelting waste recycling equipment has certain defects in actual use. In the process of recycling metal smelting waste, most of them are first crushed and then transported before recycling. A large number of fine debris are generated during crushing and transport. Although dust prevention devices are provided, most of the transport devices are still open, and a small amount of impurities will drift into the workshop during the transport process. Utility Model Content

[0004] The purpose of this utility model is to provide a dust control device for recycling metal smelting waste slag, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust control device for recycling metal smelting waste slag, comprising a crushing box, a screw conveyor, and a recycling device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model provides an embodiment of a dustproof device for recycling metal smelting waste slag, comprising a crushing box 1 for preliminary crushing of the metal smelting waste slag. The top of the crushing box 1 is equipped with a feed inlet 4 for convenient feeding (which can be connected to a conveying device for convenient conveying of the waste slag, not shown in the figure). The metal smelting waste slag can also be conveyed by other means. After feeding, the feed inlet 4 is sealed by a cover plate (not shown in the figure) to prevent dust from escaping from the feed inlet 4 during the crushing process. The crushing box 1 is equipped with a crushing device 5 (which can consist of components such as a motor, a rotating shaft, crushing fins, and gears). Other crushing equipment can also be used, which are relatively mature technologies and will not be elaborated here. Auxiliary fins 17 are installed at equal intervals inside the crushing box 1 to match the crushing fins of the crushing device 5 and improve the crushing effect. The bottom of the crushing box 1 is equipped with a screw conveyor 2 (which can be an auger screw conveyor, a relatively mature technology and will not be elaborated here) through the discharge hopper 6. The screw conveyor 2 is equipped with a recycling device 3 (which can be a rod mill, sorting and dewatering equipment to facilitate the recycling of metal smelting waste slag, or other equipment, which can be selected and set according to the actual situation, and is a relatively mature technology and will not be elaborated here).

[0023] Please see Figures 1-5A filter box 7 is installed at the bottom of the screw conveyor 2 near the discharge hopper 6 via a collection pipe 9. This design ensures dust prevention during the recycling process, preventing dust from escaping to the outside. It also facilitates internal rinsing and collection of attached debris, enabling subsequent unified recycling operations. The filter box 7 has symmetrically welded mounting plates 22 for mounting components. The mounting plates 22 have slots inside, into which mounting plates 21 slide. A filter screen 20 is installed between the two mounting plates 21 to filter the rinse water. The filter separates water from debris for easy subsequent recycling. A slot is provided on the side wall of the filter box 7, into which a pull plate 19 is movably inserted (a sealing gasket can be placed between the pull plate 19 and the slot to ensure a tight seal during assembly; the pull plate 19 has a groove at its front center for easy removal). The pull plate 19 is welded to the retaining plate 21, allowing the filter screen 20 to be easily pulled out for cleaning and collection of filtered debris. A drain pipe 10 is located at the bottom of one side of the filter box 7 for easy drainage of filtered water. For convenient adjustment and collection... Both the manifold 9 and the drain pipe 10 are equipped with electrically controlled valves 18. To facilitate rinsing of the inside of the crushing box 1 and the screw conveyor 2, the screw conveyor 2 is provided with connecting pipes 12 of the rinsing assembly at equal intervals. Spray nozzles 13 are installed at equal intervals below the connecting pipes 12. The spray nozzles 13 penetrate the screw conveyor 2 and extend into the interior, facilitating dust suppression during conveying and subsequent rinsing operations. One end of the connecting pipes 12 is connected to a water inlet pipe 11 (connected to an external water pipe), and the feed inlet 4 is equipped with the rinsing assembly. The annular pipe 15 has nozzles 16 at equal intervals and inclined below it. One end of the annular pipe 15 is connected to the water inlet pipe 14 (connected to an external water pipe), which facilitates rinsing of the feed inlet 4 and the inside of the crushing box 1, thereby facilitating dust reduction during crushing and subsequent rinsing operations. To facilitate internal drying, the crushing box 1 and the screw conveyor 2 are also equipped with a blower (which can be composed of a blower and a drying pipe, facilitating internal drying after rinsing, or other equipment; this is a relatively mature technology and will not be described in detail here).

[0024] Working Principle: In use, the metal smelting waste to be crushed is added to the crushing box 1 through the feed inlet 4. The crushing device 5, in conjunction with the auxiliary fins 17, performs the crushing operation. Water is sprayed through the water inlet pipe 14 and the nozzle 16 under the annular pipe 15 to suppress dust during the crushing process. The crushed waste then enters the screw conveyor 2 through the discharge hopper 6, where it is transported. It then passes through the connecting hopper 8 into the recycling device 3 for further recycling. During the conveying process, water is passed through the water inlet pipe 11 and the connecting pipe 12, and sprayed through the nozzle 13 to suppress dust inside the screw conveyor 2, preventing dust accumulation due to fine particles. To prevent dust generation and ensure safety, after use, water is continuously introduced through inlet pipe 11 and inlet pipe 24, and sprayed through nozzles 13 and 26 to rinse the inside of feed inlet 4, crushing box 1, and screw conveyor 2, washing away the debris. At the same time, the electric control valve 18 on collection pipe 9 is opened, and the debris flows into filter box 7 along with the water. The debris is filtered and collected through filter screen 20, and the filtered water is discharged through drain pipe 10 for subsequent processing (it can also be used for subsequent dust suppression spraying). After rinsing, by pulling pull plate 19, the clamping plate 21 is pulled out from the mounting plate 22, and the filter screen 20 can be removed to clean up the filtered debris, collect and recycle it in a unified manner to avoid waste.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
