[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Figure 1The present invention shows a schematic structural diagram of a volume-adjustable metering device according to an embodiment, which includes: a tank body 1, a positioner 6, a movable core 5, and a flow-stabilizing baffle 7. The tank body 1 is provided with a liquid inlet 2, a liquid outlet 3, and an overflow port 4. The height of the liquid inlet 2 is higher than that of the overflow port 4, and the liquid outlet 3 is located at the bottom of the tank body 1. The positioner 6 is arranged above the tank body 1. The positioner 6 has a vertical through hole and a transverse fixed threaded hole, and a threaded fixing pin is provided in the fixed threaded hole. The movable core 5 includes a main body and a tail rod. The main body of the movable core 5 is located inside the tank body 1. The tail rod of the movable core 5 passes through the upper wall of the tank body 1 and through the through hole of the positioner 6. The tail rod of the movable core 5 can move up and down along the through hole. The threaded fixing pin of the positioner 6 is used to fix the tail rod of the movable core 5 at different height positions. The flow stabilizing baffle 7 is arranged inside the tank body 1 to reduce the fluctuation of the liquid level when the liquid is introduced through the liquid inlet 2.

[0020] The positioner 6 can be welded on the top of the tank body 1. The bottom of the tank body 1 can be designed as an arc-shaped head structure to facilitate draining the liquid in the tank body 1. The volume adjustable metering device can include multiple flow stabilization baffles 7 to improve the flow stabilization effect.

[0021] The tail rod of the positioner 6 may be provided with graduated markings to visually indicate to the operator the position of the main body of the movable core 5 within the tank body 1, thereby enabling quick and accurate adjustment of the effective volume of the metering device. A transparent observation window may also be provided on the side wall of the tank body 1 to allow the operator to observe the internal liquid level without opening the tank body, thereby facilitating operation and ensuring metering accuracy.

[0022] The tank body 1, the liquid inlet 2, the liquid outlet 3 and the overflow port 4 can be made of stainless steel and have a long service life.

[0023] The main body of the movable core 5 can be made of polytetrafluoroethylene material, which is hollow in the middle and has a specific gravity of 1.0, so that the movable core 5 is in a micro-suspended state in the solution.

[0024] In one embodiment, the exterior of the movable core 5 is coated with a corrosion-resistant coating to enhance its service life and stability in different chemical media.

[0025] To use this new adjustable metering device, a set volume of water is first measured and pumped into tank 1 through liquid inlet 2. The movable core 5 is then adjusted downward to raise the liquid level in tank 1 until it reaches overflow port 4, completing the calibration of tank 1. After the water is drained, a set volume of material is pumped in, and the excess material overflows through overflow port 4, completing the metering process. To change the volume of the metering tank, the above process is repeated, allowing the same metering tank to measure different volumes of material.
