Description

Technical Field

[0001] The utility model relates to the field of ethylene glycol storage equipment, in particular to an ethylene glycol storage tank residue processing device. Background Art

[0002] In corporate production, ethylene glycol, as an important chemical raw material, generally requires a special storage tank. The bottom of the existing storage tank is generally horizontal, without considering that after each use, liquid and residue will remain at the bottom of the tank and cannot be drained. After long-term use, it will affect the quality of the liquid stored in the tank. Although the patent with patent number ZL201220358043.3 has made a solution to the residue, in actual application, water cannot guarantee that the residue on the filter net can be completely washed away, and the residue with a slightly larger diameter cannot fall off the filter net and be cleaned up. Utility Model Content

[0003] In view of the above, the utility model provides an ethylene glycol storage tank residue processing device to solve the problems existing in the above-mentioned prior art.

One end of the rotating shaft passes through the inner wall of the discharge pipe, is connected to the inner wall in a sealed and rotating manner, and is fixed in the middle position of the filter screen.

[0006] The cleaning component includes a flushing pipe, a drain pipe, a first solenoid valve and a second solenoid valve that can close the upper and lower sides of the filter to form a sealed space, and a third solenoid valve and a fourth solenoid valve to avoid affecting daily storage and use. The first solenoid valve and the second solenoid valve are arranged in the discharge pipe and are located on the upper and lower sides of the filter. The flushing pipe is tilted on the discharge pipe, the third solenoid valve is arranged in the flushing pipe, and the flushing end of the flushing pipe corresponds to the mesh surface of the filter. The drain pipe is tilted on the discharge pipe, and the fourth solenoid valve is arranged in the drain pipe and is located at the connection between the drain pipe and the discharge pipe.

[0007] Preferably, the height at which the flushing pipe is connected to the discharge pipe is less than the setting height of the first solenoid valve.

[0008] Preferably, the height at which the drain pipe is connected to the discharge pipe is greater than the setting height of the second solenoid valve.

[0009] Preferably, a high-pressure water pipe can be connected to the water inlet of the flushing pipe.

[0010] Preferably, the second solenoid valve is arranged obliquely in the discharge pipe, and the inclination angle is the same as the inclination angle of the drain pipe.

[0011] The beneficial effects of the utility model are:
