In this embodiment, the tank 1 is arranged horizontally, and two ends of the tank are open. In this embodiment, the end caps 11 at the two ends are in a detachable sealing connection with the tank body 1 in a flange connection manner, so that a closed space is formed inside the tank body 1, and cleaning and maintenance can be performed on the inside of the tank body 1 by detaching the end caps 11 at the two ends. In addition, the end cover 11 is not limited to the above-mentioned installation method, the end cover 11 at one end can be fixedly connected with the tank body 1 by welding or an integral forming method, and the end cover 11 at the other end can be detachably connected with the tank body 1 by a flange connection method. The end caps 11 at the two ends are respectively provided with a conveying pipeline 12 communicated with the tank body 1. The central axis direction of the conveying pipe 12 coincides with the central axis direction of the tank 1.
