Method for Preventing Wax Blockage in Pipeline of Fully Enclosed Automatic Dehydrator and Its Anti-Clogging Wax Heating Control System

Abstract

The present invention relates to a biological tissue dewatering machine, and belongs to the technical field of pathologic analysis detection equipment. The method for preventing a full-closed automatic dewatering machine pipeline from clogging is characterized by comprising: 1) preparing an anti-clogging paraffin heating control system; 2) firstly heating a paraffin cylinder heater, a paraffin inlet pipe heater, a paraffin discharge pipe heater and a work cylinder heater to a temperature of 65-75 DEG C, and maintain a constant temperature state; 3) after completing the paraffin exit program running, outflowing the paraffin and the small particles incapable of exiting under the normal pressure effect out of a paraffin discharge pipe, a paraffin inlet pipe and a control valve; 4) after completing all paraffin treatment program work, running a delaying residue paraffin exit program before a reagent is loaded if the next step is loading the reagent, and then continuously performing other works; and 5) during the biological tissue dewatering machine running process, if an external power failure situation occurs, supply power for the whole machine through an internal power failure protection system. With the method and the system, the paraffin clogging resistance can be achieved, the smooth pipeline can be maintained, and the normal running of the sample treatment program can be ensured.

Description

technical field [0001] The invention relates to an automatic biological tissue dehydrator, which belongs to the technical field of pathological analysis and inspection equipment, and is mainly used for automatic dehydration, transparency, and wax dipping of biological tissues, in particular to a fully enclosed vacuum-pumped automatic biological tissue dehydrator The anti-blocking wax method and the anti-blocking wax heating control system thereof. Background technique [0002] The existing fully enclosed automatic dehydration machine for vacuuming biological tissues includes a frame, a control valve, an air pump, a gas pipe, a pipeline distribution valve, a working cylinder, a wax cylinder, etc., and the working cylinder and the wax cylinder are fixed on the frame respectively. The working cylinder cover is hinged, and the wax cylinder cover is hinged on the wax cylinder. The bottom of the wax cylinder is connected with the control valve by the wax inlet pipe, and the bottom...

Problems solved by technology

Since the paraffin solidifies below 60°C, the residual paraffin in the pipeline after each use is easy to block the wax pipe, control valve and wax discharge pipe. Especially in the case of a sudden power failure, the paraffin will quickly solidify in the pipeline, making it difficult to work next time. conduct
