Description

Technical Field

[0001] The present invention relates to the technical field of cleaning devices, and in particular to a cleaning device and a cleaning method for silicon dioxide scaling equipment. Background Art

[0002] Fluorosilicic acid is produced as a by-product during the production of wet phosphoric acid. Fluorosilicic acid is used as a raw material to produce anhydrous hydrogen fluoride. This process technology is already very mature and meets the relevant requirements of industrial policies. It is an encouraged process project for comprehensive resource utilization. In the prior art, most of the equipment in the above process is prone to scaling, and the scaling component is mainly sticky silica. When the reaction container is used for a long time, the scaling becomes thicker and thicker, which can easily lead to blockage of the container equipment and failure of the flow, and then cause failure of the container equipment and facilities and then cause system shutdown. In view of this situation, low-concentration hydrofluoric acid can be used for circulating cleaning, which can achieve good cleaning effect, reduce workload and improve equipment operation effect. However, in the above-mentioned cleaning operation steps, aqueous acid with a concentration of about 25% is pumped into the container equipment to be cleaned for immersion or circulation cleaning. The immersion cleaning method is not only time-consuming, but also easy to be not cleaned thoroughly, thereby reducing the cleaning quality. The circulation cleaning method requires repeatedly pumping the aqueous acid in and out, which increases the operation steps and reduces the cleaning efficiency.

The drive shaft 10 rotates stably under the limit of the stable seat 34, so that the drive shaft 10 drives the stirring blade 36 and the crushing blade 12 fixedly sleeved at the bottom thereof to rotate. Under the stirring action of the stirring blade 36, as the rotation speed of the stirring blade 36 increases, the aqueous acid solution gradually forms a vortex, and the outer side of the vortex gradually increases, so that the aqueous acid solution enters the higher part of the inner wall of the reaction container 3 The double-axis motor 35 is started to be soaked and softened, so that the water acid can be fully mixed with the scale, which is convenient for subsequent cleaning. Then, the double-axis motor 35 is started to rotate forward and reverse indirectly, so that the double-axis motor 35 drives the screw 8 fixedly connected at one end to rotate, and the other end drives one of the gears 31 to rotate, so that the gear 31 drives the gear ring 30 to rotate in the fixed frame 26.

Under the action of the large spring 21, the two plate brushes 4 are reset by pulling the pressure plate 15. While the plate brush 4 is cleaning, the gear 31 drives the screw 8 to rotate synchronously, thereby The connecting sleeve 7 thereon is driven to reciprocate along the axial direction of the screw rod 8, and the connecting action of the connecting plate 22 indirectly drives the brush 4 to reciprocate up and down on the inner wall of the reaction vessel 3, thereby realizing all-round cleaning of the inner wall. While the connecting plate 22 drives the pressure plate 15 to move, the pressure plate 15 slides between the ball 19 movably installed on one side thereof and the pressure rod 11, thereby reducing the friction resistance, making the sliding between the pressure rod 11 and the pressure plate 15 smoother, and the scale scraped off by the brush 4 falls to the bottom of the reaction vessel 3, and is crushed by the crushing blade 12, so that the scaling residue reacts better with the water acid, accelerates the reaction, thereby improving the cleaning efficiency, and also facilitates the subsequent discharge of waste liquid.

Then, the fixing frame (26) is fixed to the top of the reaction container (3) by slidingly connecting the end of the support rod (27) with the slot (14) provided on the upper surface of the reaction container (3); S3, then, the driving motor (29) and the double-shaft motor (35) are started, the driving motor (29) drives the driving shaft (10) to rotate, the driving shaft (10) drives the stirring blade (36) and the crushing blade disc (12) to rotate, and at the same time, under the drive of the double-shaft motor (35), the pressing rod (11) cooperates with the pressing sliding mechanism (5) to make the brush (4) slide up and down on the inner wall of the reaction container (3) and scrape, so as to remove the scale residue, and in addition, the adjustment mechanism (6) is used to adjust the position of the brush (4), so as to clean the residue on the inner wall of the reaction container (3) in all directions, and the residue under cleaning completely reacts with the water acid under the cooperation of the stirring blade (36) and the crushing blade disc (12); S4. Finally, after cleaning is completed, the pickling water is pumped into the waterless system or directly recycled into the production system by opening the solenoid valve at the bottom of the reaction vessel (3).
