Description

Technical Field

[0001] The utility model relates to the technical field of biological reagent magnetic beads, in particular to a biological reagent magnetic bead cleaning device. Background Art

[0002] Biomagnetic beads refer to superparamagnetic microspheres with small particle sizes, which generally have super strong paramagnetism. The main material inside the magnetic beads is ferrite, which is an iron-magnesium alloy with a gray-black color. It is generally used to suppress electromagnetic interference. At low frequencies, the magnetic beads mainly show inductive characteristics, and the loss during use is very small. At high frequencies, the magnetic beads mainly show reactance characteristics and change with frequency, so this type of magnetic beads has been well used in high-frequency attenuators in radio frequency circuits.

[0003] Magnetic beads need to be cleaned during the production process, but the magnetic bead cleaning equipment currently on the market cannot recycle water when cleaning the magnetic beads, which reduces resource utilization. At the same time, the existing cleaning device has a poor cleaning effect on magnetic beads. Therefore, we launched a biological reagent magnetic bead cleaning device. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By setting a first rotating motor and a second rotating motor, the second rotating motor drives a plurality of stirring blades on the mounting rod to rotate, and the first rotating motor drives the ball screw to rotate at the same time, so that the ball screw block repeatedly moves up and down, thereby driving the second rotating motor on the mounting plate to repeatedly move up and down, and then driving a plurality of stirring blades to repeatedly move up and down, thereby achieving stirring and cleaning of the biomagnetic beads in the cleaning box. This structure has good cleaning effect and high cleaning uniformity.

[0013] 2. By setting up a partition net, the water in the cleaning box is extracted through a water pump and an outlet pipe, so that the water enters the delivery pipe through the partition net and is then sprayed into the cleaning box through a nozzle for reuse. The partition net effectively isolates the garbage in the water and isolates the biomagnetic beads, thereby realizing the recycling of water and improving resource utilization.
