Due to the opening of the rectangular opening 30, the user can directly view the inner side of the installation groove 14 through the transparent glass 31 without opening the protective door 28. Therefore, it is beneficial for the user to observe the operation status of the equipment inside the installation groove 14 at all times, and thus the safety of the equipment inside the installation groove 14 is improved for the second time.

Due to the existence of the legs 22, the bottom end of the base 2 can be effectively supported. The rubber pad 24 is made of rubber and has good anti-slip ability and rubber shock absorption ability. At the same time, it can also distribute the stress area at the bottom end of the legs 22, and thus can effectively improve the stability of the placement of the base 2.

The control module 26 can uniformly control the electrical equipment on the device. It will be more convenient and fast to control the operation of the entire device through the control module 26, and at the same time, a good automatic operation effect can be achieved.

[0028] Principle of use and advantages: When the machine tool is used up and it is necessary to process the electrolytic slag generated during processing on the operating table 3, the handle 5 can be used to facilitate grasping the scraper 4, and then the scraper 4 is slid along the chute 6. The scraper 4 can scrape the electrolytic slag on the operating table 3 forward uniformly, so that the electrolytic slag can be piled up. The piled-up electrolytic slag is directly pushed into the material passing port 7, and the electrolytic slag can fall into the collection box 9 at the inner bottom end of the collection tank 8 through the material passing port 7. The collection box 9 can collect these electrolytic slags uniformly, and it is also convenient for the user to take out the collection box 9 later to process the electrolytic slags uniformly. When it is necessary to clean the electrode, through the mutual cooperation of the cleaning liquid inlet solenoid valve 16 and the electrode cleaning liquid pump 18, the cleaning liquid enters the flow channel 10. As the cleaning liquid is injected, the conductivity electrode is soaked in the cleaning liquid for a period of time to achieve a good cleaning effect. After the cleaning is completed, by opening the cleaning liquid return solenoid valve 17, the cleaning liquid in the flow channel 10 can be discharged. After the cleaning with the cleaning liquid is completed, using the same principle, through the mutual cooperation of the distilled water inlet solenoid valve 19 and the distilled water pump 21, the distilled water enters the flow channel 10. The conductivity electrode can achieve the effect of secondary rinsing under the soaking of the distilled water for a certain time, and thus a good self-cleaning effect of the electrode can be achieved. Due to the existence of the protective door 28, the inner side of the installation groove 14 can be effectively protected, and thus the safety protection of the equipment inside the installation groove 14 can be improved. Due to the opening of the rectangular opening 30, the user can directly view the inner side of the installation groove 14 through the transparent glass 31 without opening the protective door 28. Therefore, it is convenient for the user to observe the operating condition of the equipment inside the installation groove 14 at all times, and thus the safety of the equipment inside the installation groove 14 is improved secondly. Due to the existence of the bolt 13, the screwing in of the bolt 13 can effectively fix the position of the flow channel 10, and thus the displacement of the flow channel 10 can be avoided. When it is necessary to disassemble the flow channel 10, just screw out the bolt 13 from the screw hole 12, and thus it is also convenient for the user to maintain the flow channel 10 later. Due to the existence of the support legs 22, the bottom end of the base 2 can be effectively supported. The rubber pad 24 is made of rubber, has good anti-slip ability and rubber shock absorption ability, and can also share the stress area at the bottom end of the support legs 22, and thus the stability of the placement of the base 2 can be effectively improved.
