[0033] The storage container 1 has a cavity for containing the solid-containing solution, a feeding port 2 at the top and a discharging port 3 at the bottom, and a turbulence inner cylinder 4 is arranged in the storage container 1, the turbulence inner cylinder 4 is in the shape of a conical platform with the top being wider and the bottom being narrower, the top of the turbulence inner cylinder 4 is fixedly connected with the top of the storage container 1, and the bottom is suspended, and a plurality of turbulence holes 5 are uniformly distributed on the cylinder wall of the turbulence inner cylinder 4, the turbulence holes 5 are circular or elliptical, and the hole diameter gradually decreases from the top to the bottom of the turbulence inner cylinder 4, so as to adapt to the flow characteristics of the solid-containing solution at different positions and enhance the turbulence effect.

[0034] The ultrasonic vibration assembly comprises a plurality of ultrasonic vibrators 6 which are uniformly distributed and fixedly installed on the outer side wall of the storage container 1 and located at the corresponding regions of the turbulence inner cylinder, and the frequency range of the ultrasonic vibrators 6 is 20 kHz-100 kHz.

[0035] The bottom stirring assembly is located at the bottom of the storage container 1 close to the discharging port 3, and comprises a stirring motor 11, a stirring shaft 12 and a stirring paddle 13, the stirring motor 11 is fixedly installed at the bottom of the outer side of the storage container 1, the stirring shaft 12 penetrates through the storage container 1 and extends into the interior, and the stirring paddle 13 is fixed on the stirring shaft 12, and the shape of the stirring paddle 13 is a spiral blade.

[0036] The transfer pump 7 has an inlet connected with the discharging port 3 at the bottom of the storage container 1 through a pipeline and an outlet connected with a transfer pipeline 8.

[0037] The dynamic mixer 9 is installed on the transfer pipeline 8, a plurality of staggered mixing elements 10 are rotationally arranged in the dynamic mixer 9, the mixing elements 10 are made of stainless steel and are in the shape of a spiral, and the spiral directions of adjacent mixing elements 10 are opposite.

[0038] The working principle of the device for realizing anti-deposition transfer of the solid-containing solution in AKD production is as follows: the device comprehensively uses turbulence, ultrasonic vibration, stirring and dynamic mixing principles to realize anti-deposition transfer of the solid-containing solution in AKD production.

[0039] The working process of the device for realizing anti-deposition transfer of the solid-containing solution in AKD production is as follows:

[0040] 1. Solution storage and initial anti-settling: the solid-containing solution enters the storage container 1 through the feed inlet 2. The turbulence inner cylinder 4 in the storage container 1 starts to work. Since it is in the shape of a truncated cone with the upper part wide and the lower part narrow, and the cylinder wall is uniformly distributed with turbulence holes 5 with the hole diameter gradually decreasing from the top to the bottom. When the solution flows in the container, it will change the flow rate and direction to different degrees through the turbulence holes 5, forming complex turbulence, thereby effectively preventing the deposition of solid particles at the bottom of the storage container 1 and the wall of the turbulence inner cylinder 4. At the same time, the ultrasonic vibrator 6 installed on the outer side wall of the storage container 1 continuously emits ultrasonic vibration in the frequency range of 20 kHz-100 kHz. This high-frequency vibration is transmitted to the solid-containing solution in the storage container 1, making the solid particles always active and difficult to aggregate and deposit, further enhancing the anti-settling effect.

[0041] 2. Material transfer preparation: when material transfer is required, the bottom stirring assembly is started. The stirring motor 11 is fixedly installed at the bottom of the outer side of the storage container 1 and drives the stirring shaft 12 to rotate after being powered on. The spiral blade-shaped stirring paddle 13 fixed on the stirring shaft 12 rotates, stirring the solid-containing solution near the discharge outlet 3 at the bottom of the storage container 1. The rotation of the stirring paddle 13 generates strong stirring force, making the solid particles that may have deposited near the discharge outlet 3 re-suspended in the solution, ensuring uniform discharge and preparing for smooth material transfer.

[0042] 3. Material transfer process: the material transfer pump 7 is started. The inlet of the material transfer pump 7 is connected to the discharge outlet 3 at the bottom of the storage container 1 through a pipeline, and the pretreated solid-containing solution in the storage container 1 is pumped out through the outlet and pumped to the material transfer pipeline 8. When the solid-containing solution flows in the material transfer pipeline 8, it enters the dynamic mixer 9 installed on the pipeline. A plurality of stainless steel mixing elements 10 are arranged in the dynamic mixer 9, which are staggered and have opposite spiral directions. As the solution flows through the dynamic mixer 9, the mixing elements 10 continuously divide, shear and remix the solution. Since the adjacent mixing elements 10 have opposite spiral directions, the solution will be repeatedly twisted and rubbed when passing through, thereby ensuring that the solid-containing solution remains in a highly uniform state throughout the material transfer process, effectively preventing the deposition of solid particles in the material transfer pipeline 8 and ensuring that the solid-containing solution is smoothly and stably delivered to the target location.

[0043] The above describes the present application and its embodiments, which are not limiting. The embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired by this, without departing from the creative spirit of the present application, similar structural modes and embodiments can be designed without creative design, which should belong to the protection scope of the present application.
