Description

Technical Field

[0001] This utility model relates to the field of material processing, and in particular to a device for cleaning and coating the surface of silicon oxide waste. Background Technology

[0002] In the field of silica waste recycling, cleaning the surface coating is a key step in achieving resource reuse. Silica waste comes from a wide range of sources and has complex surface coating compositions. How to efficiently remove the coating while retaining a pure silica substrate is the core issue for improving the recycling value of waste. The design of related processing equipment must take into account both pretreatment effects and subsequent cleaning efficiency.

[0003] In existing technologies, the treatment of coatings on the surface of silicon oxide waste typically employs a combination of graded crushing and chemical cleaning. First, the waste is broken down into suitable sizes using crushing equipment. Then, a conveying device transfers the crushed waste to a cleaning container, where specific chemical reagents react with the coating to remove it. Simultaneously, simple screening methods are used to separate some visible impurities. The overall process can meet basic coating removal requirements and achieves a certain degree of initial recycling of silicon oxide waste.

[0004] However, in existing technologies, crushing and impurity separation are mostly independent processes. During the transportation of crushed waste, some coatings remain encapsulated due to the irregular particle shape, and magnetic coating impurities are easily carried into subsequent processes along with the material, making it difficult to remove them simultaneously during the pretreatment stage. This results in a limited contact area between the coating and the cleaning medium during subsequent cleaning. At the same time, the mixing of magnetic impurities affects the purity of the final silica waste. It is necessary to integrate crushing and magnetic adsorption functions to improve the continuity and purification effect of the pretreatment process. Therefore, a silica waste surface coating cleaning device is proposed to solve the above problems. Utility Model Content

[0040] Working principle: During coating stripping, silicon oxide waste is first fed into the crushing box 2 through the feed hopper 3. The motor 8 drives the transmission shaft 5 to rotate. Because the two sets of transmission shafts 5 are driven by meshing gears 7, the staggered crushing wheels 6 rotate relative to each other, shearing, squeezing and crushing the waste. After crushing, the waste falls onto the belt 12 through the lower funnel 4. The motor 10 drives the rotating shaft 11 to rotate, so that the belt 12 transports the waste. The magnetic strips 13 arranged at equal intervals on the side wall of the belt 12 adsorb magnetic coating impurities in the waste. When the belt 12 rotates to the slot in the mounting frame 1, the non-magnetic silicon oxide waste falls into the slot, while the impurities on the surface of the magnetic strips 13 are brushed off by the brush 15 at the top of the inclined rod 14 and slide down the inclined rod 14 to the drawer 16 below for collection. The material is then extracted by the extraction pipe 17 in the slot of the mounting frame 1. The vacuum pump 18 generates negative pressure, which pumps the silicon oxide waste in the tank to the top of the reaction tank 20 through the conveying pipe 19, completing the automated feeding. After the material is transported to the reaction tank 20, the water pump 30 is started to draw the cleaning liquid in the reaction liquid tank 31 through the water pumping pipe 29 and transport it to the reaction tank 20 to mix with the silicon oxide waste. The motor 3 23 is started to drive the rotating shaft 24 to rotate, so that the connecting column 26 drives the scraper 27 to rotate against the inner wall of the reaction tank 20 to prevent the waste from adhering. At the same time, multiple sets of stirring blades 28 stir the waste and the cleaning liquid. The heater 21 heats the material in the reaction tank 20 evenly through the spiral heating ring 25, which accelerates the chemical reaction between the coating and the cleaning liquid and realizes the coating peeling. After the reaction is completed, it can flow out through the discharge pipe 22 for subsequent rinsing, screening and drying.
