[0017] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

A central rotating shaft 7 coaxially arranged with the mixing chamber is rotatably assembled on the upper bearing seat 8 and the lower bearing seat 3, and a mixing chamber 14 with an annular structure is fixed on the central rotating shaft 7.

[0020] Specifically, the mixing chamber 14 includes an inner cylinder 10, an outer cylinder 11, and a mixing chamber cylinder bottom plate 13 disposed at the bottom of the inner cylinder and the outer cylinder of the mixing chamber. The mixing chamber 14 is located on the upper side of the discharge trough. The inner cylinder, the outer cylinder and the discharge trough are coaxially arranged, and the central rotating shaft 7 is connected to the inner cylinder 10 of the mixing chamber through a connecting frame 9.

[0021] A mixing chamber outlet 19 is arranged on the bottom plate of the mixing chamber cylinder, and an outlet valve 20 is arranged at the mixing chamber outlet. Through the rotation of the mixing chamber, the mixing chamber outlet can stay on the upper side of the corresponding outlet inlet.

[0022] In this embodiment, the height of the lower bearing seat is lower than the top height of the discharge chute cylinder, and the bottom of the mixing cavity is lower than the top height of the discharge chute cylinder.

[0023] A guide support 17 is provided on the upper side of the mixing chamber discharge port in the mixing chamber. The guide support is a plate-like structure. The one-way support is welded and fixed between the inner cylinder 10 of the mixing chamber and the outer cylinder 11 of the mixing chamber. A vertical guide rod 16 is installed on the guide support for guiding movement in the up-down direction. The discharge port valve 20 is fixedly provided at the lower end of the vertical guide rod 16. A valve reset spring 18 for applying a downward force to the discharge port valve is provided between the guide support and the discharge port valve. A guide hole extending in the up-down direction is provided in the central rotating shaft. The guide hole is a square hole. A control rod 2 is installed in the guide hole for guiding movement in the up-down direction. The control rod is a square shaft structure. There is a stop-rotation fit relationship between the control rod and the central rotating shaft, that is, the control rod cannot rotate relative to the central rotating shaft. A hand wheel 1 for torque input is provided at the upper end of the control rod.

[0024] A control rod return spring 6 is provided between the control rod and the central rotating shaft for applying an upward force to the central rotating shaft. The control rod is connected to the upper end of the vertical guide rod by a connecting rod mechanism 15. When the control rod moves downward, the connecting rod mechanism 15 moves upward with the discharge port valve 20 through the vertical guide rod 16 to open the discharge port of the mixing chamber.

[0025] A vertical long hole 5 is provided on the central rotating shaft, and the connecting rod mechanism 15 includes a transmission lever 28, which is a crank arm structure with a concave upward direction.

[0026] The liquid mixing and distributing device further comprises a plurality of feed pipes 31 which are located on the upper side of the mixing chamber and are spaced apart along the circumferential direction. The discharge direction of the feed pipes is arranged along the tangential direction of the mixing chamber.

[0027] When the present invention is in use, the outlet valve is in a closed state, and the four materials enter the mixing chamber tangentially along the mixing chamber through the corresponding feed pipes. Under the impact of the materials, the mixing chamber automatically rotates to achieve uniform mixing of the materials. Since the rotation speed of the mixing chamber and the rotation speed of the liquid material in the mixing chamber are inconsistent, the setting of the vertical guide rod is conducive to more uniform mixing. When the feed pipe stops feeding, the operator can also rotate the central shaft through the hand wheel, and then rotate the mixing chamber to achieve uniform stirring of the materials. After the materials are evenly mixed, the operator rotates the mixing chamber by means of the hand wheel to rotate the mixing chamber discharge port to the upper side of the corresponding discharge chamber. The operator presses the hand wheel, the control rod moves downward relative to the central shaft, the right end of the transmission lever tilts upward, the first connecting rod and the second connecting rod move upward with the vertical guide rod, the discharge port valve moves upward to open the mixing chamber discharge port, and the material falls into the corresponding discharge chamber through the mixing chamber discharge port, and then is pumped out to the corresponding reaction tank through the discharge chamber discharge port at the bottom of the discharge chamber. After completion, it is only necessary to release the pressure on the hand wheel, and the discharge port valve automatically closes the mixing chamber discharge port under the action of the reset spring; when it is necessary to pump materials into other reaction tanks, the mixing chamber is manually rotated to rotate the mixing chamber discharge port to the upper side of the corresponding mixing chamber, and then the hand wheel is pressed.
