[0044] Figure 4 Schematic diagram of a working bottle and a bottle cap provided according to an embodiment of the utility model. Figure 4 As shown, a bottle cap 13 is also provided at the bottle mouth of the working bottle 5. When the working bottle is working, the bottle cap 13 is removed, and when the working bottle 5 is used to store laboratory filter paper pulp, the bottle cap 13 is covered.

[0045] The working process of a laboratory filter paper pulp making device provided by the utility model is as follows:

[0046] ① Preparation: The power switch of the device is turned off, the stirring device 2 is in the raised state, the dust cover 11 is in the open position, and the valve 10 on the water inlet pipe 9 is closed and in the standby state. Open the bottle cap 13 of the working bottle 5, tear the prepared quantitative filter paper into pieces, and put them into the working bottle 5. Place the working bottle 5 on the heating plate 4.

[0047] ② Heating and soaking: Turn on the power supply, start the device, and the stirring device 2 descends to the inside of the working bottle 5. At this time, the dust cover 11 is closed, the valve 10 on the water inlet pipe 9 is opened, and the water spray pipe 3 sprays water into the working bottle 5 through the nozzle 14 in a spraying manner. The desalted water is added to the working bottle 5 from top to bottom. When the water level completely immerses the stirring piece 22, the heating plate 4 starts to heat (the temperature can be set by yourself). When the temperature reaches the set value, it is kept warm at a fixed time (the insulation time can be set by yourself). The heating and soaking process is completed when the insulation time ends (the filter paper is easier to break up and make filter paper pulp after heating and soaking). Note: If the desalted water evaporates during the heating process and the water level in the working bottle 5 is lower than the stirring piece 22, the desalted water will automatically start to spray water into the bottle to maintain a certain water level.

[0048] ③ Stirring to make filter paper pulp: After the insulation time is over, the stirring device 2 rotates (the time and speed can be set according to the specific situation). When all the filter paper pieces in the working bottle 5 are broken up into pulp, the dust cover 11 is opened, and the stirring device 2 slowly rises. At this time, the nozzle 14 sprays deionized water to wash the pulp on the stirring device 2. When the stirring device 2 rises to the top of the working bottle 5, the valve 10 on the water inlet pipeline 9 is closed, and the nozzle 14 stops spraying water.

[0049] ④Storing the filter paper pulp for future use: Turn off the power switch, remove the working bottle 5, cover the bottle cap 13, and store the filter paper pulp in the working bottle 5 for future use.

[0050] From the above description, it can be seen that the utility model provides a laboratory filter paper pulp production device, which has the functions of heating, soaking and stirring to break up the filter paper, and can automatically produce laboratory filter paper pulp. There is no need to manually produce the filter paper pulp, thus saving labor costs.

[0051] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
