In the following detailed description, many specific details are set forth in order to provide a thorough understanding of the embodiments of the utility model. However, one or more embodiments can be implemented by those skilled in the art without these specific details.

[0028] As shown in the figure, a dyeing system comprises a reagent unit 1, a plurality of liquid adding units 2, a plurality of waste liquid discharging units 3, a waste liquid pool 4 and a plurality of pipelines, the liquid adding units 2 and the waste liquid discharging units 3 correspond one by one; Figure 1 The reagent unit 1 comprises a plurality of reagent bottles 101 respectively containing different functional reagents;

[0029]

[0030] ​The liquid adding unit 2 comprises a rotary valve 201 having a plurality of inlet ends and an outlet end, a rotary valve 202, a buffer tank 203, a second valve body 204, a staining tank 205, a plunger pump 206 and a third valve body 207; the reagent bottles 101 correspond to the inlet ends of the rotary valve 201 one by one, the reagent bottles 101 and the inlet ends of the rotary valve 201 are communicated through pipelines, the outlet end of the rotary valve 201 is communicated with the inlet end of the rotary valve 202 through a pipeline; the buffer tank 203 is communicated with the outlet end of the rotary valve 202, the inlet end of the second valve body 204 and the plunger pump 206 through pipelines; the outlet end of the second valve body 204 is communicated with the staining tank 205; the third valve body 207 is connected on the pipeline between the buffer tank 203 and the plunger pump 206, and the third valve body 207 is further connected with air outside;

[0031] The waste liquid unit 3 comprises a first waste liquid filter 301, a waste liquid pipeline valve 302 and a waste liquid diaphragm pump 303, and the first waste liquid filter 301, the waste liquid pipeline valve 302 and the waste liquid diaphragm pump 303 are sequentially arranged between the staining tank 205 and the waste liquid tank 4, and the staining tank 205, the first waste liquid filter 301, the waste liquid pipeline valve 302, the waste liquid diaphragm pump 303 and the waste liquid tank 4 are sequentially communicated through pipelines.

[0032] The reagent unit 1 is composed of a plurality of reagent bottles 101, each of which contains a reagent with specific functions, such as buffer solution, hematoxylin, differentiation solution, purification solution, EA / OG staining agent and cleaning solution. These reagents are connected with each inlet end of the rotary valve 201, and the designated reagent pipeline is selected by switching different inlet ends of the rotary valve 201.

[0033] When a certain reagent is needed, the rotary valve 201 is switched to the inlet end connected with the reagent bottle 101. At this time, the rotary valve 202 is opened, the plunger pump 206 is started and a certain amount of reagent is extracted from the selected reagent bottle 101. The reagent enters the buffer tank 203 through the rotary valve 201 and the rotary valve 202. After the extraction of the reagent is completed, the rotary valve 202 is closed to prevent the reagent from flowing back. Then, the second valve body 204 is opened, and the plunger pump 206 injects the reagent in the buffer tank 203 into the staining tank 205 at a certain pressure and flow rate. After the reagent delivery is completed, the second valve body 204 is closed to avoid backflow, and then the third valve body 207 is opened to connect external air. At this time, the plunger pump 206 is reset to release the pressure in the buffer tank 203 to the outside and restore its initial state, ready for the next reagent delivery.

[0034] When it is necessary to empty the waste liquid in the dyeing tank 205, first open the waste liquid pipeline valve 302 and the waste liquid diaphragm pump 303 to make them communicate with the dyeing tank 205, then start the first waste liquid filter 301, which extracts the waste liquid from the dyeing tank 205 by the suction of the waste liquid diaphragm pump 303 and simultaneously performs preliminary filtration on the waste liquid to remove larger particles or precipitates to prevent subsequent waste liquid pipeline blockage or waste liquid tank 4 pollution.

[0035] After the waste liquid is filtered, it is transported to the waste liquid tank 4 through the pipeline. When the waste liquid in the dyeing tank 205 is completely emptied, immediately close the waste liquid pipeline valve 302 and the waste liquid diaphragm pump 303 to cut off the flow channel of the waste liquid.

[0036] As a preferred, an anti-overflow pipeline 5 is arranged between the plurality of liquid adding units 2, and the inlet end of the anti-overflow pipeline 5 communicates with the side of the dyeing tank 205 of the liquid adding unit 2, the outlet end of the anti-overflow pipeline 5 communicates with the waste liquid tank 4, and the anti-overflow pipeline 5 is further provided with a second waste liquid filter 6.

[0037] The inlet end of the anti-overflow pipeline 5 communicates with the side of the dyeing tank 205 of the liquid adding unit 2 and is located at the safe upper limit position of the liquid level of the dyeing tank 205. When the liquid level of the dyeing tank 205 is too high due to abnormal operation or other reasons, the excess liquid will automatically flow out through the anti-overflow pipeline 5, and the outlet end of the anti-overflow pipeline 5 directly communicates with the waste liquid tank 4, so that the overflow liquid can automatically enter the waste liquid tank 4, realizing unified collection and treatment of the waste liquid, wherein the second waste liquid filter 6 in the anti-overflow pipeline 5 filters the overflow liquid to remove large particles or impurities therein to prevent these impurities from entering the waste liquid tank 4.

[0038] As a preferred, a pressure sensor 7 is arranged on the pipeline between the buffer tank 203 and the plunger pump 206.

[0039] The pressure sensor 7 can monitor the pressure change in the pipeline in real time, so that the operator can timely find abnormal conditions.

[0040] As a preferred, the number of reagent bottles 101 is at least six.

[0041] As a preferred, the number of liquid adding units 2 and waste discharge units 3 is at least two.

[0042] As a preferred, the waste liquid diaphragm pump 303 communicates with the bottom of the dyeing tank 205.

[0043] The waste liquid diaphragm pump 303 communicates with the bottom of the dyeing tank 205, so that the dyeing tank 205 can minimize the waste liquid residue when discharging the reagent.

[0044] As a preferred, the buffer tank 203 is provided with a heating module and a temperature sensor.

[0045] The heating module can regulate and control the temperature of the reagent in the buffer tank 203, and the temperature sensor is used to monitor the temperature of the reagent in the buffer tank 203 in real time.

[0046] Preferably, the outer wall of the buffer tank 203 is provided with a heat preservation layer.

[0047] The heat preservation layer can effectively reduce the heat loss of the buffer tank 203 to the outside, and maintain the stability of the temperature in the buffer tank 203.

[0048] The operation steps of the dyeing system are as follows:

[0049] When the slide preparation starts, a certain amount of cleaning liquid is first injected into the dyeing tank 205 to ensure that the dyeing tank 205 is clean and ready for subsequent operation. After the slide preparation is completed, the slide is placed in the dyeing tank 205 and soaked in the cleaning liquid for preliminary cleaning. When the number of slides reaches the set requirement, such as 10 or other specified number, according to the specific setting process and dyeing time, the addition, action and discharge of the reagent are sequentially completed.

[0050] In the steps of adding, acting and discharging the reagent, the rotary valve 201 is switched to the corresponding reagent bottle 101 inlet end, and the plunger pump 206 is started to extract a certain amount of reagent from the selected reagent bottle 101, which is delivered to the dyeing tank 205 through the buffer tank 203. In the dyeing tank 205, the reagent acts on the slide, and the chemical reaction is completed according to the set dyeing time. Subsequently, the system automatically discharges the reagent or waste liquid in the dyeing tank 205, and delivers the waste liquid to the waste liquid tank 4 through the first waste liquid filter 301, the waste liquid pipeline valve 302 and the waste liquid diaphragm pump 303, while filtering the particulate matter to prevent clogging.

[0051] The principles and implementation modes of the present application are described by applying specific examples in this paper, and the above examples are only used to help understand the method and its core idea. It should be pointed out that for ordinary skilled persons in the technical field, without departing from the principles of the present application, the present application can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the claims of the present application.
