[0002] Edge material is the edge waste of monocrystalline silicon round rods cut off. These waste materials are good materials in photovoltaic single crystal production, with high silicon purity, suitable for use with crystal pulling. The edge material recycling needs to be cleaned first to remove the dust and stains on it. After cleaning, the monocrystalline silicon waste is more suitable for subsequent processing technology and can ensure the quality of subsequent products.

[0003] Traditionally, the edge materials are cleaned by soaking. The edge materials are placed in a material frame and immersed in a cleaning tank. The cleaning agent is stored in the cleaning tank and is put into the cleaning tank in batches for soaking. This cleaning method has the following problems: 1. The soaking cleaning method takes a long time, and the cleaning efficiency is low. 2. The soaking cleaning method is not clean enough, and a large amount of dust and dirt are deposited in the soaking tank, which is prone to secondary pollution. 3. This cleaning method can only be processed in batches, and cannot form a continuous production operation, which affects the production rhythm. Utility Model Content

DETAILED DESCRIPTION

[0022] like Figure 1 , 2 As shown in Figures 3 and 6, a conveying device for cleaning edge leather material is mainly composed of a plurality of cleaning conveying units 1. Each cleaning conveying unit 1 performs a cleaning operation. The cleaning conveying units 1 are repeatedly cleaned to ensure the cleaning effect. The cleaning conveying units 1 are connected side by side. The cleaning conveying units 1 at both ends are provided with a feed inlet and a discharge outlet respectively. The edge leather material 5 is cleaned once each time it passes through a cleaning conveying unit 1. The edge leather material 5 is conveyed between the cleaning conveying units 1 by a conveying chain 3, which is driven by a motor. A conveying roller assembly 2 is movably provided on the inner side of the conveying chain 3. A material shifting rod 4 is fixed at intervals on the conveying chain 3. The material shifting rod 4 shifts the edge leather material 5 along the conveying roller assembly 2 to move along the surface of the conveying roller assembly 2.

[0023] like Figure 1-6 As shown, the cleaning and conveying unit 1 comprises: an outer sealing box 1.1, an upper spray pipe 1.2, a lower spray pipe 1.3, an upper roller brush 1.4, an upper roller drive motor 1.5, a lower roller brush 1.6, a lower roller drive motor 1.7, and a back plate 1.8; a back plate 1.8 is fixed on the inner side of the outer sealing box 1.1; at least one upper roller brush 1.4 is movably provided on the back plate 1.8; the upper roller brush is located above the conveying roller member; a lower roller brush 1.6 is movably provided in the gap between the conveying roller members; an upper spray pipe 1.2 is provided above the upper roller brush 1.4; a lower spray pipe 1.3 is provided below the lower roller brush 1.6, and an upper roller drive motor 1.5 and a lower roller drive motor 1.7 are fixed to the back of the back plate 1.8; the driving ends of the upper roller drive motor 1.5 and the lower roller drive motor 1.7 respectively drive the upper roller brush 1.4 and the lower roller brush 1.6 to rotate. Since the surface of the edge material 5 is arc-shaped, the bristle surface of the upper roller brush 1.4 is provided with a groove that fits the arc of the surface of the edge material 5, so as to ensure that the upper roller brush 1.4 fits the upper surface of the edge material 5 during the cleaning process. The upper spray pipe 1.2 and the lower spray pipe 1.3 of each cleaning and conveying unit 1 are connected in series and connected to the water supply main pipe 7; more than one nozzle is arranged on the upper spray pipe 1.2 and the lower spray pipe 1.3. The upper spray pipe 1.2 sprays downward, and the lower spray pipe 1.3 sprays upward. A water tank 6 for receiving the cleaning liquid is provided at the bottom of the outer sealing box 1.1; the water tank 6 is connected to the drain pipe. The cleaned water source flows into the processing equipment from the drain pipe, and the cleaning agent after filtering and treatment can be reused. If the fixing method is not separately introduced in the above, it is welded or threaded fastened using the general technical means of technical personnel in the industry.

[0024] Here’s how it works:

[0025] The edge material 5 enters along the feed port of the cleaning conveying unit 1, and moves through the conveying roller assembly 2. The movement relies on the material moving rod 4 to follow the conveying chain 3 to drive the edge material 5 forward. In the process of moving, the surface of the edge material 5 is physically rubbed by the upper roller brush 1.4, and the bottom surface of the edge material 5 is rubbed by the lower roller brush 1.6. Spraying is performed while rubbing. A cleaning process is performed each time it passes through a cleaning conveying unit 1.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
