Technical Field

[0001] The utility model relates to the technical field of industrial fluid control, including the technical field of gravity overflow, sedimentation separation and energy-saving and environmentally friendly liquid level interface control devices, and in particular to a discharging device with adjustable liquid material interface height. Background Art

[0002] In today's industrial production process, liquid level control is a crucial but also complex and challenging link. The traditional liquid level control method generally uses a density meter or level meter in combination with a regulating valve or solenoid valve. This control method controls the discharge amount by adjusting the valve position or switching the valve, thereby further regulating the level in the container. Although this method can achieve interface control to a certain extent, there are the following problems: First, due to the limitations of the measurement principle and the equipment itself, the instrument of the traditional interface control method inevitably has certain errors, which directly affects the accuracy and stability of the control; second, the response speed of the control valve is slow and there is an obvious lag phenomenon. When the interface changes, the control valve cannot be adjusted in time, affecting the control effect; third, the physical and chemical properties of the material may interfere with the instrument and affect the accuracy of the measurement; fourth, the traditional interface control method requires regular calibration and maintenance to ensure the normal operation of the instrument and the control valve, which not only increases the complexity of the operation, but also increases the cost; fifth, the traditional interface control method needs to be connected to the instrument line and the gas source, which not only increases the wiring cost, but also may lead to waste of resources, especially the traditional design of the inverted U-shaped tube, the interface height cannot be adjusted after installation, and the interface fluctuates greatly when the load is adjusted, making it difficult to achieve stable control of the liquid level interface. Summary of the invention

[0005] According to the liquid pressure formula P = ρgh, using the principle that both sides of the liquid pressure are equal, P = ρ2g(L2-m) + ρ1gm = L1ρ1g, that is, ρ2(L2-m) + mρ1 = L1ρ1; where P is the liquid pressure, ρ is the specific gravity, g is the acceleration of gravity, h is the liquid height, L2 is the liquid level height of the upstream container 7, m is the interface height of the upstream container 7, L1 is the operating height of the inverted U-shaped tube, ρ1 is the heavy phase density, and ρ2 is the light phase density. Except for m, all other data in this equation are known.

[0018] According to the liquid pressure formula P = ρgh, using the principle that both sides of the liquid pressure are equal, P = ρ2g(L2-m) + ρ1gm = L1ρ1g, that is, ρ2(L2-m) + mρ1 = L1ρ1; where P is the liquid pressure, ρ is the specific gravity, g is the acceleration of gravity, h is the liquid height, L2 is the liquid level height of the upstream container 7, m is the interface height of the upstream container 7, L1 is the operating height of the inverted U-shaped tube, ρ1 is the heavy phase density, and ρ2 is the light phase density.

[0019] During normal operation, the liquid level height L2 of the upstream container 7 is kept unchanged, the heavy phase density is ρ1, the light phase density is ρ2, the boundary height of the upstream container 7 is m, and the inverted U-shaped tube operating height is L1; according to P=ρ2g(L2-m)+ρ1gm=L1ρ1g, it can be obtained that ρ2(L2-m)+mρ1=L1ρ1; except for m, all other data in this equation are known. Since the height of L1 can be adjusted by rotating the inverted U-shaped tube around the center lines of the two rotating joints, that is, L1 is adjustable, m can be controlled, that is, the device realizes the control of the boundary position of the upstream container.
