Description

Technical Field

[0001] This utility model relates to the field of mixing tank cleaning technology, and in particular to a mixing and cleaning structure for a sand mixing truck mixing tank. Background Technology

[0002] As a core piece of equipment in fracturing operations for oil and gas extraction, the mixing tank of the sand mixing truck needs to quickly mix fracturing fluid, proppant, and various chemical additives into a homogeneous fracturing fluid and discharge it to the fracturing truck. The homogeneous fracturing fluid with all gases removed can effectively reduce the impact and erosion on the centrifugal pump, improve the stability of the discharge pressure and the life of the centrifugal pump, which is of great significance for increasing production. However, existing mixing tank agitators mostly use single turbine and propeller blades. Although fixed baffles are added to the tank wall or agitator shaft sleeve to reduce the influence of vortices, the size of both is limited by the need to avoid interference and collision between the rotating blades and the baffles, resulting in insufficient turbulence and affecting the mixing effect. At the same time, traditional fracturing sand mixing devices often drive the agitator shaft through a motor on the upper part of the mixing tank, and sand and powder are also introduced through the upper conveying device, resulting in a complex upper structure, high precision requirements for the agitator drive equipment, and easy failure after long-term use, reducing operational efficiency.

[0003] Traditional cleaning methods struggle to comprehensively cover all areas inside the mixing tank, leaving obvious blind spots. This results in residual sand and chemical additives, making the cleaning process cumbersome, time-consuming, and water-intensive, significantly extending the interval between operations, reducing the overall efficiency of the sand mixing truck, and hindering cost control. Furthermore, the problem of incomplete cleaning remains unresolved in current technologies. While existing technologies utilize sensors to monitor the tank's contamination level in real time and automatically determine if cleaning is adequate, avoiding ineffective or incomplete cleaning, and can automatically adjust cleaning time, water flow intensity, and spray angle based on tank conditions, reducing manual operation, improving cleaning efficiency, and shortening intervals, they still suffer from incomplete cleaning. Residual impurities continue to adhere to the tank walls, mixing blades, and discharge pumps, forming stubborn scale over time, exacerbating wear and corrosion, shortening component lifespan, and increasing the frequency and cost of equipment maintenance and replacement.
