The joint of the vacuum separation tank and the one-way valve is sealed. The check valve can be fixed to the tank wall of the vacuum separation tank by a screw head and then welded at the joint.
In the above scheme, the filtration system comprises a magnetic filter, a coarse filter and a fine filter, wherein the magnetic filter and the coarse filter are connected in series with the front end of the heater, and the fine filter is connected with the rear end of the oil outlet pump.
Furthermore, an oil outlet one-way valve is connected between the oil outlet pump and the fine filter. The oil outlet pump can effectively prevent the oil product from flowing to the oil outlet pump under the action of gravity when the position of the treatment oil tank is higher than the oil filtering equipment.
The heater is provided with a temperature measuring head, and the temperature measuring head is connected with the fuzzy controller through a cable.
An infrared defoaming device is arranged on the vacuum separation tank. And a liquid level observation window is arranged on the vacuum separation tank. The window of the observation window is provided with a plurality of lamps. The oil level in the vacuum separation tank is convenient to observe.
One of the above technical solutions has the following advantage that the one-way valve can only enter the tank body from the outside, but cannot flow from the inside to the outside of the tank body. Therefore, when the high-level oil tank is subjected to purification treatment, if sudden power failure or shutdown occurs, the oil leakage phenomenon of the equipment can not occur, and the reliability of the equipment is improved.
Another technical scheme among the above-mentioned technical scheme has following advantage, and the effectual oil that has ensured the vacuum separation jar the inside can not run to the equipment outside through the solenoid valve, has avoided the pollution that the oil leak caused, has also avoided the waste that the oil leak caused.
