[0013] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0014] See as Figure 1 —— Figure 2 As shown, this specific embodiment adopts the following technical solution: it includes a weighing hopper 1, a support 2, a frame 3, a first cover plate 4, a weighing sensor 5, a liquid transition hopper 6, a second cover plate 7, a weighing hopper inlet pipe 8, a pneumatic ball valve 9, a weighing hopper outlet pipe 10, a transition hopper inlet pipe 11, a mounting base 12, and a transition hopper outlet pipe 13; the weighing hopper 1 is fixed on the frame 3, and the first cover plate 4 is fixed on the frame 3 above the weighing hopper 1, and the weighing hopper 1 and the first cover plate 4 are separately arranged. A weighing hopper inlet pipe 8 is fixed on a cover plate 4. A bracket 2 is welded to the side wall of the weighing hopper 1. The bracket 2 is fixed to the weighing sensor 5. The weighing sensor 5 is fixed to the frame 3 through the mounting base 12. The bracket 2 is located at the center of gravity of the weighing hopper 1, which can ensure the stability of the hopper. A pneumatic ball valve 9 is installed at the upper end of the weighing hopper outlet pipe 10 at the bottom of the weighing hopper 1. When a certain weight is reached, the weighing sensor 5 gives a signal, and the weighing hopper inlet pipe 8 stops the liquid from entering. The pneumatic ball valve 9 is used to release the liquid in the weighing hopper 1.

[0015] A liquid transfer hopper 6 is provided below the weighing hopper 1. A second cover plate 7 is fixed on the liquid transfer hopper 6 and placed on the frame 3. The second cover plate 7 is provided with a transfer hopper inlet pipe 11 and a hook 14. The transfer hopper inlet pipe 11 is separated from the weighing hopper outlet pipe 10, and their center lines are on the same straight line. The bottom of the liquid transfer hopper 6 is connected to the transfer hopper outlet pipe 13. The transfer hopper inlet pipe 11 does not contact the weighing hopper outlet pipe 10 to ensure the weighing accuracy of the weighing hopper 1. The liquid transfer hopper 6 is used to temporarily store liquid. The liquid transfer hopper 6 can be removed by the hook 14 to facilitate the liquid transfer out or flow directly to the next process.

[0016] The inner diameter of the transition hopper inlet pipe 11 is larger than the inner diameter of the weighing hopper outlet pipe 10, so that all the liquid flowing out of the weighing hopper outlet pipe 10 can enter the transition hopper inlet pipe 11.

[0017] The working principle of this invention is as follows: Liquid enters the weighing hopper 1 through the inlet pipe 8 on the first cover plate 4, is weighed by the load cell 5, and when the set weight is reached, the load cell 5 sends a signal, stopping the liquid inlet at the inlet pipe 8, opening the pneumatic ball valve 9, and allowing the liquid to flow out into the liquid transfer hopper 6, either transferring it out or flowing to the next process.

[0018] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
