Floating suction arm
The floating suction device , also known as the floating - bucket oil - selection arm, is an oil - discharge device that can float up and down with the liquid level in the oil tank. One end of it is connected to the short oil - discharge pipe at the bottom of the oil tank, and the other end is suspended under the liquid level by buoyancy elements such as floating buckets or floating balls. At present, for traditional oil storage tanks that send stored liquid and take liquid from the bottom of the storage tank, there are certain drawbacks for oil depots that have high requirements for the quality of stored liquid, frequent transfer operations, and require short liquid sedimentation operations.
The floating suction device is installed in vertical and horizontal liquid storage tanks. The buoyancy generated by the floating bucket makes the swivel joint move, which can ensure that the liquid - suction port of the liquid - discharge device floats up and down with the liquid level in the tank, and keeps sucking the clean liquid at the high - level part in the tank. The water and impurities deposited in the liquid layer at the bottom of the tank will not be carried out of the tank, thus ensuring the quality of the released liquid.
I. The floating - bucket oil - selection arm adopts a floating control method:
For oil tanks equipped with internal floating roofs, the front end of the device is fixed on the internal floating roof or uses its own floating box. A floating - pipe skid plate is set up on the internal floating roof to generate an adsorption and floating effect.
For oil tanks without internal floating roofs, the front end of the device is specially designed with a square or circular floating box. The entire floating device rises and falls with the liquid in the tank, and the pipe opening at the front end of the device is about 200mm below the liquid level. When oil is being issued (or discharged), it can ensure that the oil released (or pumped) is the clean oil located in the upper layer of the liquid in the tank. This device is specially designed with an anti - vortex inlet, which will not generate a vortex on the liquid surface.
II. Precautions for the floating - bucket oil - selection arm:
The floating liquid - discharge device should be installed after the tank is tested with water.
Keep the axis of the swivel joint horizontal.
Make good electrostatic bonding.
Adjust the height of each support leg to make the support leg effectively contact the bottom of the tank, and make the floating pipe basically in a horizontal state or with a slight upward angle.
When the floating liquid - discharge device is used for the first time or put back into use after the tank is cleaned, if the stored liquid cannot be discharged normally, there is air in the floating pipe. You can close the outlet valve of the tank and let the floating liquid - discharge device stand still in the liquid for 10 - 20 hours, and the floating pipe can be automatically filled with liquid. Or you can fill the floating liquid - discharge device with liquid from the liquid - discharge pipe of the tank to expel the air in the pipe.
Therefore, the floating suction device is an efficient and reliable oil - discharge device for oil storage tanks. It automatically adjusts its position with the rise and fall of the liquid level, realizing the priority release of clean fuel in the upper layer, improving the quality of oil products and reducing operating costs.
