Description

solvent storage tank

technical field

The invention relates to the technical field of solvent separation, in particular to a solvent storage tank.

Background technique

Due to the low frequency of use of household dry cleaning machines, in order to reduce the cost of use, the dry cleaning solvent needs to be recycled after washing. During the regeneration and recovery process of dry cleaning solvent, due to the small size and slow separation speed of the oil-water separator of the existing household dry cleaning machine, the oil-water separator is not easy to be directly connected with the washing drum, and the dry cleaning solvent is first stored in the dry cleaning solvent after being discharged from the outer drum of the dry cleaning machine. In the buffer tank, the dry cleaning solvent buffer tank is connected with the oil-water separator through the pipeline, and the draining speed of the dry cleaning solvent buffer tank is adjusted to control the liquid inlet speed of the oil-water separation, so that the solvent separated from the oil-water separator is stored through the pipeline into the solvent storage tank. It can be seen that, during the oil-water separation of the existing dry cleaning solvent, the operation control is complex, the separation speed is slow, the separation effect is relatively poor, and the whole separation system has a large volume.

In the solution solvent storage tank, during use, the dry-cleaning solvent flows into the primary separation chamber 10 through the pipeline, and under the action of gravity, the separation of oil and water (that is, the dry-cleaning solvent and water) is realized. After the primary separation chamber 10 is full, the separated liquid with a small specific gravity can overflow into the secondary separation chamber 9, and the liquid with a large specific gravity remaining in the liquid with a small specific gravity continues to be separated in the secondary separation chamber 9 , and flow back into the primary separation chamber 10. It can be seen that the structure of the solvent storage tank of this scheme is simple and compact, the separation operation is easy to control, two-stage separation is possible, the separation speed is fast and the effect is good.

In actual use, the solvent tank 1 can be a square box structure or a cubic box structure with an open top, and of course can also be a box structure of other structural forms, such as a cylindrical box. Partition plate 2 is set in solvent case 1, and partition plate 2 divides the cavity in the solvent case into primary separation chamber 10 and secondary separation chamber 9, and the upper and lower parts of primary separation chamber 10 and secondary separation chamber 9 are In this way, a two-stage separation structure is formed in the solvent tank, and the separation effect can be improved and the separation time can be reduced through two-stage separation. A separation chamber 5 is communicated with the bottom of the primary separation chamber 10 , and the separated liquid with a larger specific gravity gathers in the separation chamber 5 . After the solvent separation in the solvent box 1 is completed, open the first liquid discharge port 6 arranged at the bottom of the separation chamber 5 to discharge the solution with a larger specific gravity. After the discharge of the liquid with a larger specific gravity is completed. When washing is required, the second liquid outlet 7 arranged at the bottom of the secondary separation chamber 9 is opened, and the dry cleaning solvent can be sent into the washing tub of the washing machine for washing. It can be seen that the whole separation operation is easy to control.
