The working principle of the bottom-sinking prevention mechanism is that the elastic bottom diaphragm plate 10 has elasticity, and in the stirring process, along with liquid flow impact, the elastic bottom diaphragm plate can bounce, so that fuel particles deposited at the bottom are bounced, but the mode can only adapt to the state that the liquid flow fluctuation impact is obvious under the condition of changing the stirring speed. After the stirring speed reaches a certain value, the liquid flow in the dissolution chamber 2 has a relatively gentle impact, and the elastic vibration due to its own elasticity is weak. In order to solve the problem, the invention continuously fills high-pressure gas into the high-pressure vibration cavity through the air pump 12, when the high-pressure gas reaches a certain pressure, the high-pressure gas flushes the one-way pressure release valve 11 and enters the dissolving chamber 2 to form pulse aeration, thereby further promoting the stirring.
Simultaneously, compare with the direct mode of throwing into gas towards in the solution, elastic bottom diaphragm plate 10 all can produce an holistic elasticity down by a wide margin after the pressure release each time, and this kind of elasticity is elastic bottom diaphragm plate 10 holistic elasticity, so it can make whole the deposit face that is located the bottom all form the elasticity, makes the dyestuff granule suspension of deposit in the bottom. The treatment effect on the deposited dye is excellent by matching with the impact of the high-pressure aeration bubbles, so the air outlet direction of the communicating pipe of the invention is preferably towards the elastic bottom membrane plate 10, that is, the connecting pipe is preferably a bent pipe with an outlet towards the elastic bottom membrane plate 10. Certainly, because elasticity end diaphragm plate 10 need be flicked, but in order to avoid elasticity end diaphragm plate 10 to interfere with the stirring subassembly at the in-process of flicking, the top of elasticity end diaphragm plate 10 is provided with a plurality of protection billet 13 along the length direction interval of elasticity end diaphragm plate 10, protection billet 13 extends along the width direction of elasticity end diaphragm plate 10, and with dissolving chamber 2 rigid coupling. By the limitation of the protective steel bar 13, the elastic bottom diaphragm plate 10 can be prevented from being upwards transitorily bounced when the pressure of the high-pressure vibration cavity is overlarge, and the protective effect on the elastic bottom diaphragm plate is achieved.
