[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figure 1 , which is the first embodiment of the present invention, provides a filtering system for can cutting, which includes a collecting hood 100, which is arranged above the cutting robot head; a vacuum pump 200, which is detachably connected to the collecting hood 100 through a suction pipe; a filtering system 300, which is detachably connected to the vacuum pump 200 through a feeding pipe; and a collecting box 400, which is used to collect solid particles and waste trapped in the filtering system 300.

[0030] Furthermore, the collecting cover 100 is made of metal material, and the surface of the collecting cover 100 is anti-corrosive treated by electroplating.

[0031] The collecting hood 100 is located above the cutting head of the cutting robot and is close to the cutting head. It not only does not affect the normal operation of the robot, but can also freely adjust its position following the movement of the robot to maintain a stable collection effect. The collecting hood 100 can expand the coverage of the cutting area and prevent the cutting debris and the generated aerosol from spreading from the edge to the surrounding environment, causing pollution to the surrounding environment and endangering the safety of the operator.

[0032] The collecting cover 100 is made of metal material and is subjected to electroplating anti-corrosion treatment. In addition, it can also be subjected to anti-corrosion treatment by spray painting or other methods to ensure the corrosion resistance of the device when used in a nuclear environment.

[0033] Specifically, the suction pipe is made of corrosion-resistant material, and the inner walls of the suction pipe and the feed pipe are both smooth.

[0034] Furthermore, the suction pipe is configured to be bendable.

[0035] The suction pipe is made of corrosion-resistant material, which can effectively avoid corrosion when working in the radioactive area for a long time, save materials and increase service life. The feed pipe is also made of corrosion-resistant material. The inner walls of the suction pipe and the feed pipe are smooth, which can reduce the aerosol adhesion to the pipe wall. It can not only reduce the cleaning time of the staff on the pipe wall, but also ensure that the pipe wall will not suffer from corrosion caused by long-term aerosol adhesion. Similarly, it also avoids the possibility of staff being contaminated by aerosols during cleaning, ensuring the safety of the staff.

[0036] The suction pipe is bendable, that is, the corrosion-resistant material used to make the suction pipe is a soft material, which avoids the situation where the device is inconvenient to move when the cutting robot head is cutting, thereby ensuring the normal operation of the robot.

[0037] Specifically, an aerosol concentration monitor is installed in the suction pipeline.

[0038] The aerosol concentration monitor can monitor the aerosol concentration in the suction pipe in real time. When the concentration exceeds a preset threshold, an alarm is triggered and the operator adjusts the suction flow of the vacuum pump 200. The aerosol concentration monitor can also be connected to the vacuum pump 200 through a controller. When the aerosol concentration monitor detects that the aerosol concentration exceeds the preset threshold, the suction force of the vacuum pump 200 is adjusted accordingly through the controller. This real-time monitoring function effectively improves the safety of the device, can respond to emergencies that occur during the cutting process in a timely manner, and ensure the safety of the working environment.

[0039] When in use, install the collecting hood 100 near the cutting head, and ensure that the collecting hood 100 can move with the cutting head. After installation, connect the suction pipe and the vacuum pump 200. The vacuum pump 200 is installed on the box containing the filtration system 300. When working, turn on the vacuum pump 200, and the vacuum pump 200 generates negative pressure to absorb the aerosols and fixed particles generated by cutting, and enter the filtration system 300 through the suction pipe and the feed pipe. After layer by layer filtration of the filtration system 300, clean air is discharged to ensure the safety of the working environment.

[0040] Example 2

[0041] Reference Figure 1, which is the second embodiment of the present invention, and is different from the first embodiment in that: it also includes a filtration system 300 including an installation box 306, a primary filter 301, a HEPA filter 302 and an activated carbon filter 303, and the primary filter 301, the HEPA filter 302 and the activated carbon filter 303 are all slid in the installation box 306.

[0042] Furthermore, the outer ring of the installation box 306 is fixedly connected to the fixing plate 304 , and a support frame 305 is provided below the fixing plate 304 . The support frame 305 and the fixing plate 304 are fixed by threads.

[0043] Furthermore, the contact portions of the primary filter 301 , the HEPA filter 302 and the activated carbon filter 303 with the installation grooves in the installation box 306 are all provided with sealing strips.

[0044] The primary filter 301 is used to capture larger particles, which refer to particles with a diameter greater than 5 μm. The HEPA filter 302 is used to capture smaller aerosol particles, which refer to particles with a diameter less than 5 μm. The activated carbon filter 303 is used to filter harmful gases and odors adsorbed in the aerosol to ensure that the air discharged from the filtration system 300 is safe.

[0045] The primary filter 301, the HEPA filter 302 and the activated carbon filter 303 are all slidably matched with the installation grooves in the installation box 306, so that they can be independently taken out from the side of the installation box, and because the installation grooves in the installation box 306 and the contact parts with the primary filter 301, the HEPA filter 302 and the activated carbon filter 303 are all provided with sealing strips, the sealing of the connection is ensured after the primary filter 301, the HEPA filter 302 and the activated carbon filter 303 are installed in the installation box 306, so as to prevent the gas with peculiar smell or poison from overflowing the installation box 306.

[0046] The cooperation between the support frame 305 and the fixing plate 304 can ensure the stability of the filtering system 300 and ensure that the aerosol can be filtered stably. The setting of the installation groove makes it easy for the operator to take out the primary filter 301, the HEPA filter 302 and the activated carbon filter 303 independently, which is convenient for the subsequent cleaning and replacement of the primary filter 301, the HEPA filter 302 and the activated carbon filter 303, and the operation is relatively convenient.

[0047] The arrangement of the primary filter 301, the HEPA filter 302 and the activated carbon filter 303 can efficiently filter aerosol particles of different particle sizes, especially tiny particles containing radioactive substances, to prevent them from leaking into the environment again during the collection process. By using the HEPA filter 302 and the activated carbon filter 303, the device can not only capture particles, but also absorb harmful gases and odors, greatly reducing the risk of secondary pollution.

[0048] Preferably, the installation slot in the installation box 306 presents a certain angle with the installation box 306, and the angles presented by the two installation slots are different. For example, from the top to the bottom of the installation box, the first installation slot is measured from the opening of the installation box 306 to the direction of the opening, and the installation slot gradually moves away from the upper opening of the installation box 306, while the second installation slot is the opposite. From the opening of the installation box 306 to the direction of the opening, the installation slot gradually approaches the upper opening of the installation box 306. The first installation slot and the second installation slot are arranged in a horizontal figure eight. When the wind direction in the vacuum pump 200 drives the cutting particles to pass through the primary filter 301 and the HEPA filter 302, since the primary filter 301 and the HEPA filter 302 follow the inclined setting of the installation slot, more stable filtration can be achieved, and the primary filter 301 and the HEPA filter 302 can be prevented from being blocked, thereby ensuring the normal operation of the device.

[0049] Furthermore, the contact portion between the mounting groove and the primary filter 301 and the HEPA filter 302 is sealed with an elastic sealing strip. When the negative pressure generated by the vacuum pump 200 drives the particles to fall onto the primary filter 301 and the HEPA filter 302, it can cause the primary filter 301 and the HEPA filter 302 to vibrate slightly. Combined with the inclined setting of the primary filter 301 and the HEPA filter 302, a better filtering effect can be achieved.

[0050] Preferably, the surface of the primary filter 301 and the HEPA filter 302 may also be wavy, and the height distance between the highest point and the lowest point of the wave should not be too large, and the length distance between the highest point and the lowest point is relatively long. When the negative pressure drives the particles to fall onto the surface of the primary filter 301 and the HEPA filter 302, since the primary filter 301 and the HEPA filter 302 are inclined, the particles move on the primary filter 301 and the HEPA filter 302 due to the influence of the negative pressure and their own gravity. The wavy shape can not only collect the particles, but also will not affect the capture of the particles. It can also make the filtration more complete and is not easy to cause clogging of the primary filter 301 and the HEPA filter 302.

[0051] During use, when the gas containing particles sucked in by the vacuum pump 200 enters the filtration system 300, it first passes through the primary filter 301 to capture particles larger than 5 μm, and the gas continues to flow in the installation box 306 with smaller particles. When passing through the HEPA filter 302, it can capture particles smaller than 5 μm. Then the toxic gas will enter the activated carbon filter 303, and the toxic substances and odors in the gas will be removed by the activated carbon filter 303. Then the filtered safe air is discharged from the bottom of the installation box 306.

[0052] Example 3

[0053] Reference Figure 1 , which is the third embodiment of the present invention, is based on the first two embodiments, and provides a filtering method for can cutting, the steps comprising

[0054] S1: Install the collection cover 100 above the cutting robot head, ensure that the collection cover 100 covers the cutting area, and connect the collection cover 100 to the vacuum pump 200 through a suction pipe;

[0055] S2: Start the vacuum pump 200 to suck the particles generated by cutting through the suction pipe and transport them to the filtering system 300 through the conveying pipe;

[0056] S3: The filter system 300 filters the input particles and filters and discharges the inhaled air;

[0057] S4: Turn off the vacuum pump 200, remove the collection cover 100 and the suction pipe, and clean the filter system 300.

[0058] Specifically, before starting the vacuum pump 200 to absorb the cut particles, the airflow path is tested to ensure that the cut particles effectively enter the collection cover 100 .

[0059] During use, testing the airflow path sucked by the vacuum pump 200 in advance can effectively prevent incomplete absorption of aerosol particles during formal use, thereby preventing environmental pollution.
