Description

Technical Field

[0001] The present application relates to the technical field of metal waste cleaning, and in particular to an eddy current cleaning machine for metal waste. Background Art

[0002] Scrap metal cleaning plays a vital role in metal recycling and reuse. Its primary purpose is to remove impurities, grease, dust, and other contaminants from the scrap's surface, laying a solid foundation for subsequent processing, separation, or reuse. Scrap metal cleaning removes surface impurities such as oxides, salts, and grease. Cleaning makes it easier to identify and separate the active components within the scrap metal, thereby improving recycling efficiency. Scrap metal cleaning can also reduce the emission of hazardous substances and mitigate the risk of environmental pollution.

[0003] Currently, the methods for cleaning metal scrap include ultrasonic cleaning, chemical cleaning, and mechanical cleaning. Chemical cleaning, through the contact of cleaning agents with metal scrap, can dissolve or react with impurities on the surface of the metal scrap, and can quickly and thoroughly achieve a cleaning effect. It is widely used in the cleaning of metal scrap. At present, in the process of cleaning metal scrap by chemical cleaning, the metal scrap is placed in a cleaning cylinder, and cleaning water and chemical reagents are added in proportion, and the chemical reagents and cleaning water are mixed and then react with the impurities on the surface of the metal scrap. Due to the different types of impurities, such as the different thicknesses of the surface oxide layer on the surface of the metal scrap, the self-reaction time of the chemical reagents and the impurities, oxide layer, etc. is inconsistent, resulting in a long cleaning time. There is also the problem of incomplete cleaning, which makes the quality after cleaning uneven and difficult to guarantee, affecting the subsequent recycling quality of the metal scrap. Summary of the Invention

[0004] In response to the above-mentioned problems, the present application aims to provide a vortex cleaning machine for metal scrap, which, under the combined action of chemistry and mechanics, enables the cleaning water containing chemical reagents to rotate together with the metal scrap, and under the action of external force, enhances the contact between the cleaning water and the metal scrap, thereby achieving complete cleaning of the metal scrap and improving the consistency of cleaning.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a vortex cleaning machine for metal scrap, comprising a cleaning cylinder, a discharge port is provided on one side of the bottom thereof, and is characterized in that a driving impeller is provided at the bottom of the cleaning cylinder, a driving structure for forming a vortex effect is provided on the outer wall of the cleaning cylinder, a collecting bag is detachably provided at the discharge port, and a collecting trough for receiving the collecting bag is provided.

[0006] Preferably, the driving structure is a driving plate provided on a certain arc length section of the side wall of the cleaning cylinder.

[0007] Preferably, the inner bottom surface of the cleaning cylinder is configured as a curved surface structure inclined from the driving impeller toward the side wall.

[0008] Preferably, the cambered surface structure is configured as a slope structure facing in the opposite direction of rotation of the driving impeller.

[0009] The beneficial effect of the present application is that the cleaning machine drives the rotation of the impeller, and under the combined action of chemical and mechanical forces, the cleaning water fused with chemical reagents and the metal waste rotate together, and under the action of external force, the cleaning water and the metal waste are in enhanced contact, thereby accelerating the cleaning efficiency of impurities on the surface of the metal waste. At the same time, under the action of the mechanical external force, the cleaning water fused with chemical reagents can fully contact with the impurities on the surface of the metal waste, thereby achieving complete cleaning of the metal waste and improving the consistency of cleaning.

[0016] In order to enable ordinary technicians in this field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0017] Refer to the attached Figures 1 to 5The vortex cleaning machine for metal scrap shown in the figure includes a cleaning drum 1, a discharge port 11 being provided on one side of the bottom thereof, and a driving impeller 2 being provided at the bottom of the cleaning drum 1, which is driven to rotate by a driving motor. During cleaning, after metal scrap, cleaning water, and chemical reagents are added to the cleaning drum 1 in proportion, the driving impeller 2 is driven to rotate. Under the combined action of chemical and mechanical forces, the cleaning water containing the chemical reagents and the metal scraps rotate together. Under the action of external force, the cleaning water and the metal scraps are in enhanced contact, thereby accelerating the cleaning efficiency of impurities on the surface of the metal scraps. At the same time, under the action of the mechanical external force, the cleaning water containing the chemical reagents can fully contact the impurities on the surface of the metal scraps, thereby achieving complete cleaning of the metal scraps and improving the consistency of cleaning.

[0018] In order to further improve the driving effect during the cleaning process of metal waste, the present application sets the outer wall of the cleaning cylinder 1 as a driving structure that forms a vortex effect. Under the driving action of the driving impeller 2, the driving structure causes the mixture of the rotating waste and the cleaning water to form a vortex state, thereby achieving sufficient mixing of the metal waste and the cleaning water, thereby further strengthening the contact effect between the cleaning water (reagent) and the metal waste, and improving the cleaning effect of the metal waste.

[0019] like Figure 1 As shown, a collection bag (not shown) and a collection tank 3 for receiving the collection bag are detachably provided at the discharge port 11. After the cleaning is completed, the mixture of the metal scrap and the cleaning water is discharged into the cleaning bag through the discharge port 11. The metal scrap and the cleaning water are filtered through the cleaning bag, and the cleaning water is filtered into the collection tank 3. The metal scrap in the bag is then dried and can be reshaped into usable metal raw materials.

[0020] Specifically, such as Figure 2 As shown, the driving structure is a driving plate 12 provided on a certain arc length section of the side wall of the cleaning cylinder 1. The mixture of metal scrap and cleaning water is driven to rotate by driving the impeller 2 ( Figure 2 As shown by the arrow a in the middle, when the mixture contacts the driving plate 12, the driving plate 12 and the center radius of the cleaning cylinder 1 are reduced, thereby exerting a reverse impact on the mixture (extrusion, such as Figure 2 As shown by arrow b), the mixing effect of metal scrap and cleaning water is increased, and the cleaning effect is thereby enhanced. When the rotation speed reaches a certain value, the center of the cleaning cylinder 1 can further form a vortex hollow, such as Figure 3 The state shown in FIG. 1 makes the mixture squeezed again toward the inner wall of the cleaning cylinder 1 ( Figure 3 The mixed contact and cleaning effects are further enhanced.

[0021] In order to further increase the mixed contact effect of metal scrap and cleaning water, Figure 4 As shown, the inner bottom surface of the cleaning cylinder 1 is configured as an arc surface structure inclined from the driving impeller 2 toward the side wall ( Figure 4 As shown in c). Due to the gravity of the mixture of metal scrap and cleaning water, the mixture is moved under the action of the curved surface structure. Figure 4 As shown by the middle arrow, the impeller 2 is driven to squeeze the mixture toward the side wall of the cleaning tube 1, so that the mixture is squeezed again toward the inner wall of the cleaning tube 1, and the mixing contact and cleaning effect are further increased.

[0022] Since the metal raw material and the cleaning water rotate synchronously in the process of being driven by the driving impeller 2, the metal raw material and the cleaning water rotate synchronously, and under the action of the eddy current achieved by the driving plate 12, there is a speed difference between the metal raw material and the cleaning water, thereby achieving full mixing. In order to further improve the mixing effect of the metal raw material and the cleaning water, as shown in FIG. Figure 5 As shown, the arc surface structure is set as a slope structure facing the opposite direction of the driving impeller. The driving impeller 2 drives the mixture to Figure 5 The cleaning drum 1 rotates in the direction of the middle arc arrow, and the inner bottom surface of the cleaning drum 1 is a slope structure, which realizes the resistance in the uphill direction of the rotation of the mixture, so that the rotation speed difference between the metal raw material and the cleaning water is further increased, thereby further improving the mixing effect of the two and ultimately improving the cleaning effect and cleaning efficiency of the metal raw material.

[0023] The principle of the present application is: during cleaning, metal scrap, cleaning water and chemical reagents are added to the cleaning drum 1 in proportion, and the impeller 2 is driven to rotate. Under the combined action of chemical and mechanical forces, the cleaning water fused with chemical reagents and the metal scrap rotate together. When the mixture contacts the driving plate 12, it has a reverse impact on the mixture, thereby increasing the mixing effect of the metal scrap and the cleaning water. The arc surface structure and the slope structure further improve the mixing effect of the metal raw material and the cleaning water, thereby improving the cleaning consistency and cleaning efficiency.

[0024] The above shows and describes the basic principles, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will also have various changes and improvements, which fall within the scope of this application.
