Clarifying oil tank is the most commonly used crude oil sedimentation separation equipment. After being used for oil extraction by pressing, the cake residue in the pressed crude oil can be separated and removed in time. The clear oil tank produced by Huatai Grain and Oil Machinery Co., Ltd. has a good effect on the settlement of coarse cake slag in crude oil. It can mechanized slag removal and slag return. Its structure is simple, easy to install, use and maintain; Reliable; high production efficiency, low energy consumption and other characteristics and advantages.

The main working principle of the clear oil tank is gravity sedimentation separation, which uses the difference in relative density between the suspended impurities and the oil, and makes the suspended impurities settle down from the oil and separate from the oil in the natural static state. The oil tank is a cuboid, and the motor drives the transmission device in the box to make the scraper conveyor rotate. There is a set of special grid plates on the oil tank. The crude oil containing residue is sent into the clear oil tank by the oil scraper, and after standing and settling, the crude oil flows from the overflow pipe into the clean oil pool through several partitions, and then is pumped into the oil filter unit to further separate the fine oil contained in it. scum. The scraper conveyor moves continuously at a very low speed. The scraper on the conveyor scrapes up the oil residue that sinks to the bottom of the box. When passing through the sieve plate above, the oil contained in the oil residue leaks into the box through the sieve holes. , while the cake residue moves to the other end of the box with the scraper, falls into a scraper conveyor across the oil tank, and is sent to the oil press for re-pressing.

Installation and commissioning of clear oil tank

Installation method

The clear oil tank is directly placed on the concrete, and the small sprocket of the reducer and the large sprocket of the clear oil tank are fixed in a straight line before adjustment and test run.

Debugging method

1. Clean up debris, check whether all parts are in good condition, check whether the cycloidal pinwheel reducer, and whether the pipe joints are in good condition.

2. Check the lubrication system, inject lubricating grease to ensure that the lubricating oil is sufficient, check the oil level in the cycloid reducer, and add No. 20 mechanical oil if it is insufficient.

3. Turn the motor wheel by hand to drive the scraper chain to run. Adjust the speed of the scraper chain tensioning mechanism to make the chain moderately tight. The scraper chain is on the light wheel. The height is in the middle of the chain length, and it is advisable to lift it by hand at a height of 50-80mm.

4. Check the wiring of the motor to make sure that its direction of rotation is the specified direction.

5. Adjust the position of the cycloid reducer to ensure the safe operation of the chain.

6. Start the test run, check the surrounding baffles, wiring boards, etc., and do not hinder the operation of the chain scraper.

7. Run without load, check whether the operation is balanced, whether the chain mesh is normal, whether there is any abnormal sound, if there is any abnormality, stop and check.
