Description

Technical Field

[0001] This utility model relates to the field of liquid transfer technology, specifically a liquid transfer and replenishment device. Background Technology

[0002] Currently, air separation units mainly use cryogenic distillation to obtain oxygen and high-purity nitrogen. During the initial design phase, air separation unit cooling losses and liquid production are fully considered. However, as the air separation unit ages, the temperature difference in the plate heat exchanger increases, leading to increased cooling losses, especially during hot summer months. This cooling loss can even cause some units to cease continuous operation. The only way to ensure continuous operation is to reduce cooling losses by lowering the load. This application proposes a liquid transfer device to replenish cooling capacity, sending cryogenic liquid to the distillation column to replenish cooling capacity and ensure high-load operation of the unit.

[0003] A search revealed an existing patent (publication number: CN205973545U) that discloses an automatic universal can-tilting device for chemical applications, comprising a base, a crossbar, a can-tilting rack support, and a pulley support. The base is equipped with wheel supports, universal wheels, and a rotatable hydraulic rod. The wheel supports are located at the bottom edge of the base and welded to it. The rotatable hydraulic rod is located in the center of the base. The rotatable hydraulic rod can be used for raising and turning, facilitating different heights and directions required for can-tilting by workers. A counterweight can be used to balance the pressure effect of can-tilting on the other side of the crossbar. A battery allows the device to operate in locations without a fixed power source. A hinge connects the can-tilting rack support and the can-tilting rack, allowing the rack to rotate and tilt at the required angle. A steel cable can be used to raise and lower the can-tilting rack, controlling its operation and stopping. This utility model of an automatic universal can-tilting device for chemical applications is functionally practical and structurally simple, solving the safety problem of manual pouring of hazardous liquids during industrial can-tilting processes.

[0004] It solves the problem of eliminating the need for manual pouring, but it has a drawback: it lacks a clamping mechanism, which could cause the tank to fall during pouring. Utility Model Content

[0012] Beneficial effects

[0013] This invention provides a liquid transfer and replenishment device. Compared with the prior art, it has the following advantages:

[0014] 1. This liquid tank-sinking replenishment device, by setting up a tank-sinking mechanism, starts the lifting motor, which drives the lifting wheel to rotate and loosen the hoisting rope, so that the tank-sinking mechanism descends and places the liquid storage tank inside the tank-sinking mechanism. Then, the lifting motor is started in reverse, so that the liquid storage tank rises. Then, the rotating motor is started, the front pull rope is wound up and the right pull rope is loosened, so that the liquid storage tank tilts and allows the liquid inside to flow out, replenishing the cooling capacity of the distillation column and ensuring the high-load operation of the unit.

[0015] 2. This liquid refilling device, by setting up a clamping mechanism, activates the hydraulic rod, which retracts, causing the cross plate to rise. The cross plate, along with the vertical rod and the ring, rises, causing the fixing rope to pull the rotating ring. The rotating ring rotates and squeezes the clamping block, which moves to clamp the liquid storage tank. This prevents the liquid storage tank from falling out of the refilling mechanism when it is tilted. Attached Figure Description

A hanging rope 15 is wound and fixed to the outer wall of the lifting wheel 17. The other end of the hanging rope 15 passes through the support rod 19 and is fixedly connected to the top of the cross 12. Two limiting rods 2 are slidably connected inside the cross 12.

[0025] During operation, the lifting motor 18 is started, which rotates the lifting wheel 17 to loosen the hoisting rope 15, causing the tilting mechanism 6 to descend and place the liquid storage tank inside. The lifting motor 18 is then started in reverse, causing the liquid storage tank to rise. Next, the rotating motor 14 is started, causing the front pull rope 10 to wind up and the right pull rope 10 to loosen, thus tilting the liquid storage tank and allowing the liquid inside to flow out, providing cooling to the distillation column and ensuring high-load operation of the unit.
