Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to an external protective device for CNC machine tools with flue gas treatment function. Background Technology

[0002] Currently, most CNC machine tools are enclosed processing equipment, with protective doors and covers installed on the outside of the machine tool to prevent waste chips from scattering outside during processing. However, during processes such as laser cutting and welding, a certain amount of fumes and exhaust gases are generated. When the protective devices are opened, the irritating gases can easily be inhaled and cause harm to the human body.

[0003] For example, Chinese utility model patent application number 202420293358.7 discloses an external protective device for CNC machine tools with flue gas treatment function. This external protective device for CNC machine tools with flue gas treatment function is equipped with a reaction chamber, a suction hood, a filter cartridge, and an air pump. The suction hood and air pump can quickly draw the flue gas inside the CNC machine tool into the reaction chamber. The liquid in the reaction chamber reacts with the harmful gas substances in the flue gas, thereby purifying the flue gas. At this time, the air in the space above the liquid will flow into the filter cartridge through the exhaust pipe due to air pressure. The filter cartridge is equipped with a filter element, which can perform secondary purification treatment on the gas entering the filter cartridge. After the treatment is completed, it is discharged. The purification effect is better. At the same time, the suction hood, reaction chamber, and fixing frame are all installed on the CNC machine tool with bolts, which is very convenient for installation and disassembly.

[0004] Although the device in the aforementioned patent can filter the absorbed flue gas by mixing and reacting the liquid with harmful substances in the flue gas, it lacks a mixing device in actual use, resulting in low mixing efficiency between the liquid and harmful substances in the flue gas. In addition, when the liquid needs to be replaced after use, the device needs to be stopped and can only be restarted for filtration after the liquid is replaced, which reduces the practicality of the device.

One end is fixedly connected to a threaded rod 11, and the top of the machine tool body 2 is fixedly connected to a fixing block 13. The fixing block 13 is threadedly connected to the threaded rod 11. The adjusting cylinder 8 is fixedly connected to the filter box 4 through two connecting pipes 12. The ends of the two connecting pipes 12 away from the adjusting cylinder 8 are fixedly extended into the filter box 4. The machine tool body 2 is equipped with a drive assembly and a flue gas absorption assembly. Through the arrangement of the base 1, machine tool body 2, filter box 4, partition 5, stirring plate 7, adjusting cylinder 8, piston 9, threaded rod 11 and transmission mechanism 23, the liquid can be stirred, improving the mixing reaction efficiency of the liquid and harmful substances in the flue gas. At the same time, during the use of the device, the liquid on both sides of the partition 5 can be used alternately, which is convenient and quick to discharge and replace the liquid after one side is used, and does not require stopping the operation of the machine tool body 2, thereby improving the practicality of the device.

[0020] A support frame 17 is fixedly connected to the top of the filter box 4. A transmission mechanism 18 is connected between the outer surfaces of the two connecting rods 6. The drive assembly includes a motor 19 fixedly installed at the bottom of the support frame 17. The output end of the motor 19 is fixedly connected to the top of one of the connecting rods 6. By starting the motor 19, with the cooperation of the transmission mechanism 18 and the transmission mechanism 23, the two connecting rods 6 and the corresponding stirring plate 7 can be driven to rotate, improving the mixing reaction efficiency of liquid and harmful substances. At the same time, the rotating shaft 21 and several fan blades 22 can be driven to rotate, extracting the flue gas inside the machine tool body 2. This not only improves energy utilization but also further enhances the practicality of the device.

[0021] The flue gas extraction assembly includes an annular box 20, which is mounted on the machine tool body 2. A rotating shaft 21 is rotatably connected inside the annular box 20. The top end of the rotating shaft 21 is rotatably sealed to the outside. Several fan blades 22 are fixedly connected to the outer surface of the rotating shaft 21. A transmission mechanism 23 is connected between the outer surface of the rotating shaft 21 and the outer surface of one of the connecting rods 6. The annular box 20 is fixedly connected to the adjusting cylinder 8 and the suction hood 3. Two fixing plates 24 are fixedly connected to the top of the machine tool body 2.

[0022] The working principle of this utility model is as follows: When in use, first open the two feed pipes 14 to add an appropriate amount of liquid into the filter box 4, and then close the feed pipes 14.

Under the transmission of the first transmission mechanism 18 and the second transmission mechanism 23, drive the other connecting rod 6 and the corresponding stirring plate 7 to rotate. The rotating shaft 21 and several fan blades 22 rotate synchronously. The rotating fan blades 22 draw the flue gas inside the machine tool body 2 through the suction hood 3 and transport it to the regulating cylinder 8. Under the interception of the piston 9, the flue gas is transported to the filter box 4 through one of the connecting pipes 12 and into the liquid on the same side of the partition 5. The stirred liquid adsorbs and filters the impurities in the flue gas and reacts and mixes the harmful substances. The filtered flue gas is discharged through the corresponding one-way exhaust pipe 15. When the liquid on one side of the partition 5 needs to be replaced during the use of the device, manually rotate the threaded rod 11 to move the push rod 10 towards the fixed block 13. The push rod 10 drives the piston 9 to move synchronously. After the movement, the other connecting pipe 12 is connected to the annular box 20 through the adjusting cylinder 8, so that the sucked flue gas is transported to the liquid on the other side of the partition 5 for reaction and filtration. At this time, the solenoid valve on the side of the liquid to be replaced can be energized to open it and discharge the liquid to be replaced. After discharge, the solenoid valve is de-energized, and the corresponding feed pipe 14 can be opened again to add an appropriate amount of liquid to the side of the partition 5 for subsequent use.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
