This process not only requires multiple manual additions of ground powder, making the operation too cumbersome, but also the substances in the phenol are toxic. If they come into contact with the skin, they will cause certain damage to the body of the tester. Utility Model Content

[0005] As a further improvement of the present technical solution, a cleaning assembly for cleaning the grinding roller is arranged inside the shell and above the grinding roller. The cleaning assembly includes a horizontal plate fixed to the top of the shell and passing through the fixed plate. A scraper for cleaning the surface of the grinding roller is installed at the bottom end of the horizontal plate.

[0006] As a further improvement of the technical solution, an elastic component is arranged between the scraper and the cross plate to enable the scraper to fit tightly against the surface of the grinding roller.

Since the dephenolizing agent is generally an alkaline substance, a phenanthroline reagent is generally used to detect the dephenolizing content in crude phenol, but both crude phenol and phenanthroline are solids, and the two substances need to be ground into powder first, and then manually added to the test tube, mixed with water to form a reagent, and finally one of the reagents is poured into the other reagent to complete the detection of the dephenolizing agent. This process not only The grinding powder needs to be added manually many times, which makes the operation too complicated, and the substances in phenol are toxic to a certain extent. If they come into contact with the skin, they will cause certain damage to the body of the inspector. Due to the setting of the fixed plate, the interior of the shell 3 is divided into a first grinding chamber and a second grinding chamber, and the two chemical substances to be detected can be ground and crushed at the same time, which improves the grinding efficiency to a certain extent. Before work, the two chemical substances, crude phenol and phenanthroline, are respectively put into the first grinding chamber and the second grinding chamber, and then the servo motor 6 is turned on to drive the rotating shaft 4 to rotate. At this time, the rotating shaft 4 drives the grinding rollers 5 located in the first grinding chamber and the second grinding chamber to rotate, and grinds and crushes the chemical substances to be detected. During the grinding process, the finer ground powder will enter the conical block from the filter screen 7 16, because the conical block 16 is provided with a cavity inside and the inner surface has a certain inclination angle, the two powders can be collected at one time, and then the valve 17 is opened to control the demand, and the crude phenol powder and the phenanthroline powder are respectively put into the transparent reagent tube 8. Because the content of the dephenolizing agent in the crude phenol is detected, the phenanthroline powder is put into the long transparent reagent tube 8, and the crude phenol powder is put into the short transparent reagent tube 8. After that, water is injected from the water injection channel 9 into a pair of transparent reagent tubes 8 to mix evenly with the internal powder, and then the water stop valve 18 is opened to make the crude phenol reagent solution flow into the phenanthroline reagent solution from the connecting pipe 10. The content of the dephenolizing agent in the crude phenol is determined by the color comparison method, using the dephenolizing agent and phenanthroline to react chemically to present different colors.

[0022] See also Figure 2 , Figure 3 As shown, a cleaning assembly for cleaning the grinding roller 5 is arranged inside the housing 3 and above the grinding roller 5. The cleaning assembly includes a horizontal plate 11 fixedly connected to the top of the housing 3 and penetrating the fixed plate. A scraper 12 for cleaning the surface of the grinding roller 5 is installed at the bottom of the horizontal plate 11. An elastic assembly for the scraper 12 to fit tightly against the surface of the grinding roller 5 is arranged between the scraper 12 and the horizontal plate 11. The elastic assembly includes a plurality of sleeves 13 fixedly connected to the bottom end of the horizontal plate 11. A reset spring 14 is fixedly connected to the bottom end of the sleeve 13. A slide column 15 is fixedly connected to the bottom end of the reset spring 14, and the slide column 15 slides on the inner wall of the sleeve 13. The scraper 12 is fixedly connected to the bottom ends of multiple slide columns 15. When the servo motor drives the grinding roller 5 to rotate and grind, powder will adhere to the surface of the grinding roller 5. Through the cooperation between the scraper 12, the slide column 15, the reset spring 14 and the sleeve 13, the slide column 15 can have a tendency to move downward under the action of the reset spring 14, so that the scraper 12 can always be in contact with the grinding roller 5, which makes it easy to clean the grinding roller 5.

[0023] Working principle: Before work, the two chemical substances, crude phenol and phenanthroline, are put into the first grinding chamber and the second grinding chamber respectively, and then the servo motor 6 is turned on to drive the rotating shaft 4 to rotate. At this time, the rotating shaft 4 drives the grinding rollers 5 located in the first grinding chamber and the second grinding chamber to rotate, and grinds and crushes the chemical substances to be detected. During the grinding process, the finer ground powder will enter the interior of the conical block 16 from the filter screen 7. Because the interior of the conical block 16 is provided with a cavity and the internal surface has a certain inclination angle, the two powders can be collected at one time, and then the valve 17 is opened to control the demand, and the crude phenol powder and phenanthroline powder are respectively put into the transparent reagent tube 8. Because it is a test of the dephenolizing agent content in the crude phenol, the phenanthroline powder is put into the long transparent reagent tube 8, the crude phenol powder is put into a short transparent reagent tube 8, and then water is injected from the water injection channel 9 into a pair of transparent reagent tubes 8 to mix evenly with the internal powder, and then the water stop valve 18 is opened to allow the crude phenol reagent solution to flow from the connecting pipe 10 into the phenanthroline reagent solution, and the content of the dephenolizing agent in the crude phenol is determined by the color comparison method by utilizing the chemical reaction between the dephenolizing agent and phenanthroline to present different colors. When the servo motor drives the grinding roller 5 to rotate and grind, powder will adhere to the surface of the grinding roller 5. Through the cooperation between the scraper 12, the slide column 15, the return spring 14 and the sleeve 13, the slide column 15 can produce a downward movement tendency under the action of the return spring 14, so that the scraper 12 can always be in contact with the grinding roller 5, so as to facilitate the cleaning of the grinding roller 5.
