[0002] The online weighing and equalizing powder feeding tank is a system device used in industrial production for precise control of powder material conveying, mainly applied in industries such as chemical, food, pharmaceutical, and building materials. The online weighing and equalizing powder feeding tank mainly consists of a tank body, weighing system, powder feeding mechanism, pneumatic conveying system, and control system, ensuring accurate metering and stable powder delivery. During weighing, multiple load cells are installed at the bottom of the tank or on the supporting structure, allowing for online weighing. However, the load cells bear the pressure of the tank body and the material, and disassembly requires tools to rotate bolts, which is time-consuming and labor-intensive, presenting certain drawbacks. Therefore, we propose an online weighing and equalizing powder feeding tank. Utility Model Content

A discharge pipe is fixedly installed at the bottom of the tank body, and a discharge valve is fixedly installed on the discharge pipe. The fixed base is fixedly installed on the outside of the tank body. The weighing sensor abuts against the bottom of the fixed base. The support column is fixedly connected to the weighing sensor, and a limit rod is provided at the top of the support column. The overload protection component includes a nut threadedly connected to the limit rod, a rotating plate rotatably connected to the top of the nut, a spring fixedly installed at the top of the rotating plate, and a ring fixedly installed at the top of the spring. The quick-release component includes a rotating rod rotatably connected to the support column and a stop block fixedly installed on the rotating rod.

[0005] Preferably, the top of the tank is fixedly provided with a feed pipe and an exhaust pipe, and a feed valve and an exhaust valve are fixedly provided on the feed pipe and the exhaust pipe, respectively.

[0006] Preferably, it also includes an air inlet pipe, which is fixedly installed on the tank body and the discharge pipe, and an air inlet valve is fixedly installed on the air inlet pipe.

[0007] Preferably, the fixing base has two limiting holes, both of which are round holes.

[0008] Preferably, the top of the support column is provided with a mounting slot for installing a weighing sensor.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: The nut of the overload protection component can be rotated upward, thereby driving the rotating plate, spring and ring to move until the ring supports the fixed seat. The overload protection component can then support the raised tank. The fastening knob of the quick-release component can be loosened, thereby rotating the stop block until it no longer obstructs the load cell. At this point, the load cell can be directly removed. This process does not require tools, which is convenient for maintenance and replacement, saving time and effort. At the same time, the spring has a certain elastic potential energy, which allows the ring to buffer the tank, effectively preventing the tank from damaging the load cell due to overload.
