Mixing tank for fracturing sand mixing equipment

The invention discloses a mixing tank for fracturing sand mixing equipment. The mixing tank comprises a main tank body with an opening formed in the top, wherein a liquid inlet pipe is arranged at thetop of the main tank body and communicated with the main tank body, a V-shaped flow channel is formed in the bottom of the main tank body, a liquid outlet pipe is communicated with the bottom of theV-shaped flow channel, an upper support is horizontally and fixedly connected to the top of the main tank body, one side of the main tank body is communicated with a sand collecting hopper, an annularflow channel is formed in the main tank body, the main tank body is integrally of a single-layer structure, and base liquid flows in from one or more liquid inlet pipes on the side face of the top ofthe main tank body, enters the closed annular flow channel after being divided by a partition plate, and then flows out of the flow guide hole of the lower sealing plate to enter the tank body to befully mixed with sand conveye
