Embodiment Construction

[0011] figure 1 Among them, the nozzle 4 of the hematoxylin delivery pipe 1 is connected with the water delivery pipe 2 through a three-way pipe 3 . The hematoxylin liquid enters the water delivery pipe 2 through the nozzle 4 of the hematoxylin delivery pipe 1 and is discharged, and is transported to the designated place.

[0012] The hematoxylin delivery pipe 1 and the water delivery pipe 2 are connected with respective delivery pumps. The conveying pump is connected with the computer and accepts the program instructions of the computer.

[0013] A method for preventing hematoxylin from clogging pipelines is carried out according to the following steps;

[0014] A The delivery pump of the hematoxylin delivery pipe 1 connected to the water delivery pipe 2 stops working, and the delivery of liquid hematoxylin is stopped. The hematoxylin residual liquid in the water pipe 2 stops flowing, and remains statically in the hematoxylin delivery pipe 1 and the water delivery pipe 2;...

Abstract

The invention relates to methods for preventing hematoxylin from blocking pipes, particularly to a method for preventing the hematoxylin from blocking a pipe on biological slice production dyeing equipment. The method is characterized in that a pipe opening of a hematoxylin conveying pipe is closed and blocked by the residual liquid water in a water conveying pipe. According to the method for preventing the hematoxylin from blocking the pipe, the method is simple, the production cost is low, the operation is simple and easy, the problem that the pipe is blocked due to the hematoxylin oxide crystallization can be solved, the pipe dredging work during boot-up is reduced, the convenience is brought to the work of the operators, and the damage to the equipment can be avoided.

Description

technical field [0001] The invention relates to a method for preventing hematoxylin from clogging pipelines, in particular to a method for preventing hematoxylin from clogging pipelines on biological sheet dyeing equipment. Background technique [0002] Hematoxylin is a staining agent, which is commonly used in the process of staining various tissues and cells. Hematoxylin is easily oxidized and crystallized in air. In the prior art, after the hematoxylin is transported through the pipeline under the action of the delivery pump, the front end of the hematoxylin liquid at the outlet of the pipeline, after contacting with air, is rapidly oxidized and crystallized into blocks, causing pipeline blockage. For general equipment, after being shut down for two to three days, when it is turned on again, it is necessary to dredge the pipeline before proceeding. The clogging situation is particularly serious on the bio-slice dyeing equipment with small consumption and thinner deliver...
