Embodiment 1

[0032] Such as figure 1 As shown, a transmission and drying device for granulating silicon particles from waste silicon mud, including a belt conveyor 1, a buffer plate 2, a material tray 3, a conveyor belt 4, a loading crane 5, a discharging crane 6, and a material rack 7 , Ground guide rail 8, hydraulic tractor 9, drying room 10, overturning type blanking device 11. Wherein the belt conveyor 1 is installed obliquely upward, and the buffer plate 2 is installed obliquely downward between the belt conveyor 1 and the conveyor belt 3 . Feeding pit groove 12 is set between conveyer belt 3 and ground guide rail 8, and feeding row crane 5 is just installed on the top of feeding pit groove 12. The hydraulic tractor 9 is installed on the ground guide rail 8, and the ground guide rail 8 extends through the drying room 10 to the discharge pit 13. The top of the unloading pit 13 is installed with an unloading line crane 6, and the overturning type unloading device 11 is installed behin...

Embodiment 2

[0040] like image 3 As shown, the transfer and drying methods of granulated and formed silicon particles from waste silicon mud mainly include the steps of loading into trays, racking, drying, unloading, and bagging, as follows:

[0041] Step 1: Enter the disk

[0042] The granulated silicon particles (3-5 cm in diameter) are conveyed in batches to a height of 1.1-1.2 m above the ground through a belt conveyor, and then slide down through the buffer plate to the empty material tray placed on the conveyor for receiving silicon particles middle.

[0043] Step 2: Put it on the shelves

[0044] Manually assist the silicon particles in the material tray to be stacked in double layers (the stacking density is 0.7~0.8 g / cm 3 . ), the stacked material trays are conveyed by stainless steel roller conveyors. The end of the conveyor is the feeding pit. The height of the material rack in the feeding pit is adjusted by the lifting of the feeding crane, and the material tray with a to...

Abstract

The invention discloses a waste silicon sludge granulation forming silicon particle conveying and drying method and device, and belongs to the technical field of solid forming material transfer and drying. According to the method and device, silicon particles obtained after waste silicon sludge granulation forming are transported in batches through a mechanical conveying device to a drying room which is internally provided with a high-temperature heat source, a fan and a dehumidifying port, then static drying is performed, and dried formed materials are prepared. A technological process of themethod can comprise tray loading, support loading, drying and unloading. According to material characteristics of forming waste silicon sludge and physical requirements of the silicon particles during and after drying, key factors affecting silicon particle drying are combined, while the drying efficiency is improved and the energy consumption and labor cost are reduced, efficient conveying and drying of the waste silicon sludge after granulation are achieved, and therefore, the waste silicon sludge granulation forming silicon particle conveying and drying method and device are of crucial significance in the field of conveying and drying of solid materials.

Description

technical field [0001] The invention relates to the technical field of conveying and drying solid materials, in particular to the transfer and drying of silicon particles formed by granulation of diamond wire cutting waste silicon mud. Background technique [0002] The drying technology of solid materials is widely used in many industrial productions. The traditional drying method is the most convenient and economical method of drying materials, but it requires a wide space and the drying speed is slow and time-consuming, the work efficiency is low, and it is also affected by various factors such as weather, so it is difficult to apply in the industrial field. In the solar photovoltaic industry, silicon wafer cutting (single crystal silicon, polycrystalline silicon) will produce a large amount of cutting silicon powder. Silica mud. Due to the high value of silica fume (the market price is 80,000 to 100,000 yuan / ton) and the fine particles (average particle size is less tha...
