Meanwhile, the filter screen is adopted to replace the filter paper, the filter hoppers are detachably connected, after the filter liquid is filtered, the filter hoppers can be detached, impurities in the filter hoppers are cleaned, the filter hoppers can be continuously used next time, and waste of the filter paper is avoided.

Description

Filtering device

Technical Field

The utility model belongs to the filtration equipment field, in particular to filter equipment.

Background

Filtration is an operation method commonly used in medicine, and refers to an operation that under the action of a driving force or other external forces, liquid (or gas) in a suspension (or exothermic gas containing solid particles) permeates through a medium, and the solid particles and other substances are intercepted by the filter medium, so that the solid and other substances are separated from the liquid (or gas).

Currently, the filtering operation is mainly performed by using filter paper, and in the process of performing the HE dyeing operation, the hematoxylin dyeing solution is frequently reused, so that impurities with different particle sizes are mixed in the hematoxylin dyeing solution, and the impurities need to be filtered before use. At present, the hematoxylin staining solution is filtered by adopting a mode of adding filter paper into a single funnel, and because impurities with different particle sizes are contained in the hematoxylin staining solution, the filter paper is easy to block due to single-layer filtration, the filter paper needs to be replaced for many times, and then the low filtration efficiency and the waste of the filter paper are caused.

SUMMERY OF THE UTILITY MODEL

In the process of filtering the filtrate by the filter hopper, because impurities can inevitably block part of the liquid from moving downwards, a motor is arranged, a cam is driven to rotate by the motor and abuts against a connecting rod, and when the longer end of the cam abuts against the connecting rod, the longer end of the cam pushes the connecting rod to move towards one side of a spring and drives the filter hopper to rotate forwards; when the shorter side of the cam is opposite to the connecting rod, the spring restores to the initial length to push the connecting rod to move to one side of the cam and drive the filter hopper to rotate reversely; and then realized filtering the fill and constantly switched between just reversing, at the filtering the fill and carry out pivoted in-process for impurity takes place the vibration, is favorable to moving down of liquid.

Furthermore, the cam is a gear rotating in the vertical direction, two connecting holes are formed in the gear, and one connecting hole is coaxial with the gear; the connecting rod is vertically provided with a tooth, and the connecting rod is meshed with the gear through the tooth. The cam is the gear, and is equipped with two connecting holes, accomplishes the filtration when the filtrate, when needing to fight and clear up filtering, will with the coaxial connecting hole of gear and the output shaft of motor, rotate the in-process at the motor and drive the connecting rod and rise, and then drive the filter fill and rise, take off the filter fill that needs clear up can, it is more convenient to use.

Further, a sliding plate used for shielding the rodent is connected to the connecting rod in a sliding mode. Through setting up the slide, when needs gear drive connecting rod when the horizontal direction removes, shelter from the rodent through the slide, reduce the friction between gear and the rodent, use safelyr.

Furthermore, the liquid outlet end of the filter barrel is funnel-shaped. The liquid outlet end of the filter barrel is arranged to be funnel-shaped, so that the filtrate is convenient to collect.
