Description

A microsphere washing device

technical field

The invention relates to a microsphere washing device.

Background technique

Traditional microsphere washing and separation device technologies mainly rely on the use of screens with specific pore sizes to separate liquid media from microspheres. When the liquid passes through the screen, the microspheres are trapped, thus achieving separation.

However, we have found in actual operation that the impurities that fall off the microspheres in the sieve drum will block the sieve holes after agglomeration and cannot pass through the sieve holes, which makes the water outlet efficiency in the sieve drum less than the water inlet efficiency , so that the liquid level in the sieve cylinder increases, and it needs to be shut down for emergency maintenance.

However, the current cleaning method for the built-in screen drum on the market is to fix a cleaning scraper on the rotating shaft, and the scraper cleans the inner wall of the screen drum along with the movement of the rotating shaft.

Although the above-mentioned technical scheme can complete the dredging of the screen drum, there are the following disadvantages:

The scraper is always in contact with the inner wall of the screen cylinder, resulting in a large rotation resistance of the shaft.

The scraper is always in contact with the inner wall of the screen cylinder, resulting in rapid wear or deformation of the scraper, and the contact surface between the scraper and the screen cylinder is also worn, resulting in the above-mentioned scraper being unable to touch the screen without artificially adjusting the gap. inner wall of the barrel.
