TECHNICAL FIELD
[0001] The present application belongs to the technical field of cleaning, and relates to a slurry stirring and cleaning device. BACKGROUND
[0002] In industrial production, a stirring tank is a common device and is widely used in mixing and stirring operations of slurry. The stirring tank rotates at high speed through internal stirring blades to fully mix various materials to meet specific production process requirements. After continuously producing a certain amount of slurry, the stirring tank needs to be cleaned, for example, using a N-mode cleaning mode to ensure that the quality of the subsequent production slurry is not contaminated and the normal operation of the equipment is ensured.
[0003] However, in the actual use of the stirring tank, when cleaning is performed and the stirring tank is inclined, due to the certain viscosity and adhesion of the slurry, a large amount of attached slurry is left on the inner wall of the stirring tank and the surface of the stirring blades. These attached slurry tightly adheres to the tank wall and the blades, bringing great difficulty to the cleaning work. The traditional cleaning method often cannot completely remove these stubborn attached slurry, not only consuming a large amount of manpower, material resources and time, but also affecting the quality of the next batch of slurry due to incomplete cleaning, leading to unstable product quality, and even possibly affecting the service life and stirring performance of the stirring tank due to the accumulation of residual slurry.
[0004] In view of the problem of difficult cleaning of the stirring tank, there are currently the following solutions. For example, a high-pressure water jet cleaning device uses the strong impact force of high-pressure water jet to clean the stirring tank. This method can to some extent flush away part of the attached slurry, and has the advantage of greater cleaning force and better cleaning effect for some relatively loose slurry; but the disadvantage is that it has poor cleaning effect for some dead angle positions and extremely high viscosity slurry, and the high-pressure water jet may cause some wear to the inner wall of the stirring tank and the stirring blades. There is also a method of using a specific chemical cleaning agent to react with the attached slurry to cause it to decompose and separate. This method has the advantage of better decomposition effect for some stubborn stains and can improve the completeness of cleaning; but the chemical cleaning agent may cause corrosion to the material of the stirring tank, and subsequent environmental protection treatment of the cleaning waste liquid is required, increasing production cost and environmental protection pressure. Considering various factors in actual production, such as protection of the equipment, stability of the cleaning effect, cost control and environmental protection requirements, a new type of slurry stirring and cleaning device needs to be developed, which can effectively remove the attached slurry on the inner wall of the stirring tank and the stirring blades, avoid damage to the equipment, and meet the requirements of environmental protection and cost control.
