[0032] See also Figure 1-8 The present invention provides a metal dust filtering and collecting device, comprising a metal dust filtering and collecting chamber 1, the top of the metal dust filtering and collecting chamber 1 is penetrated and fixedly connected with an air inlet port 2, and the outer wall cover of the air inlet port 2 is provided with a first connecting frame 3 and a second connecting frame 4, the bottom ends of the first connecting frame 3 and the second connecting frame 4 are both provided with a connecting chamber 15 for clamping a connecting column 17, and the inner top of the connecting chamber 15 is inlaid with a first magnetic sheet 16, the bottom end of the first magnetic sheet 16 is magnetically attracted to the top of the second magnetic sheet 18 fixedly connected to the top of the connecting column 17, and the connecting column 17 is fixedly connected to the top of the metal dust filtering and collecting chamber 1 with a symmetrical center of the top of the air inlet port 2, the inner side walls of the first connecting frame 3 and the second connecting frame 4 are both fixedly connected with a silicone sealing pad 9 arranged with a silicone material structure, and the outer side wall of the silicone sealing pad 9 is tightly fitted with and in conflict with the outer side wall of the air inlet port 2.

[0033] By setting up the first connecting frame 3 and the second connecting frame 4, during the process of collecting metal dust by the device, the first connecting frame 3 and the second connecting frame 4 are covered on the outer wall of the air inlet port 2, so that the air inlet port 2 can be flexibly connected with the bellows 7 and the air inlet 8, and the bellows 7 and the air inlet 8 can be quickly separated during use, thereby achieving the purpose of quick-release cleaning of the bellows 7, the air inlet 8 and the air inlet port 2. The first connecting frame 3 and the second connecting frame 4 are covered on the outer wall of the air inlet port 2. The specific fixing method is that the first connecting frame 3 and the second connecting frame 4 are mutually clamped, and the connecting cavity 15 opened at the bottom end of the first connecting frame 3 and the second connecting frame 4 is clamped on the top outer wall of the connecting column 17, and at the same time, the first magnetic suction plate 16 and the second magnetic suction plate 18 are magnetically attracted to each other, thereby completing the quick-release fixing of the first connecting frame 3 and the second connecting frame 4.

[0034] The first connecting frame 3 and the second connecting frame 4 are both provided with a limiting cavity 5 with a semicircular ring structure in the corresponding interior, and the diameter between the two corresponding limiting cavities 5 and the inner wall height are adapted to the outer wall diameter and height of the limiting block 6, the limiting block 6 is clamped inside the limiting cavity 5, and the top end of the limiting block 6 is connected to the bottom end of the bellows 7, the top end of the bellows 7 is fixedly connected to the air inlet 8, and the top end of the air inlet 8 is fixedly connected to the metal protective net.

[0035] By setting the limiting cavity 5, after the first connecting frame 3 and the second connecting frame 4 are mutually engaged, the limiting block 6 is engaged with the inside of the limiting cavity 5, so that the first connecting frame 3 and the second connecting frame 4 are connected and fixed with the bellows 7 and the air inlet 8, and correspond to the air inlet port 2 at the same time to transmit the inhaled gas. At the same time, during the operation of the device, through the characteristics of the bellows 7, the bellows 7 can be bent according to the use requirements, and then the angle of the air inlet 8 can be changed, so that the air inlet 8 can be flexibly adapted to the working area where metal dust is easily generated, thereby improving the metal dust suction effect of the device during use.

[0036] A plug-in block 12 and a plug-in cavity 10 are fixedly connected to one side of the vertical outer wall of the first connecting frame 3 and the second connecting frame 4 respectively. The plug-in block 12 and the plug-in cavity 10 provided on the vertical outer wall of the first connecting frame 3 and the second connecting frame 4 are both corresponding structures. The inner top of the plug-in cavity 10 is evenly spaced and fixedly connected with a first limiting protrusion 11. The top of the plug-in block 12 is provided with a groove, and the inside of the groove is fixedly connected with a flexible sheet 13. The top of the flexible sheet 13 is evenly spaced and fixedly connected with a second limiting protrusion 14. The first limiting protrusion 11 and the second limiting protrusion 14 are both semi-cylindrical structures.

[0037] During the process of mutual snap-fitting assembly of the first connecting frame 3 and the second connecting frame 4, the vertical surfaces of the first connecting frame 3 and the second connecting frame 4 correspond to each other, so that the plug-in blocks 12 and the plug-in cavity 10 provided on the vertical surfaces of the first connecting frame 3 and the second connecting frame 4 also correspond to each other, so that the plug-in blocks 12 are all plugged into the interior of the plug-in cavity 10, and the first limiting protrusion 11 and the second limiting protrusion 14 are mutually in conflict, thereby completing the limiting of the plug-in block 12 and completing the mutual snap-fitting assembly of the first connecting frame 3 and the second connecting frame 4. In this way, when cleaning or maintaining the device, it is convenient to separate the first connecting frame 3 and the second connecting frame 4, and the quick-release design is adopted to improve the practicality and convenience of the device.

[0038] Both ends of the bellows 7 are set with hard material structures, and the middle section of the bellows 7 is set with a flexible material structure. The outer wall of the bottom end of the bellows 7 is fixedly connected with the first gear 19, and the outer wall of the first gear 19 is meshed with the outer wall of the second gear 20. The bottom end of the second gear 20 is transmission-connected to the top of the third gear 21 through a transmission rod, and the outer wall of the third gear 21 is meshed with the outer wall of the fourth gear 22. The top of the fourth gear 22 is fixedly connected to the output end of the first motor 23, and the third gear 21 and the fourth gear 22 are both rotatably connected to the top of the metal dust filter collection chamber 1.

[0039] By setting the first motor 23, during the metal dust collection operation, the first motor 23 rotates at a uniform speed, thereby driving the fourth gear 22 fixedly connected to the output end to rotate at a uniform speed, thereby driving the meshing third gear 21 to rotate at a uniform speed, and because the top of the third gear 21 is fixedly connected to the second gear 20 through a transmission rod, the second gear 20 is linked to rotate synchronously, and because the outer wall of the second gear 20 is meshed with the outer wall of the first gear 19, the first gear 19 is finally driven to rotate at a uniform speed, and the bellows 7 and the air inlet 8 are both rotated at a uniform speed, so that the surrounding air can be inhaled with the device as the center point, thus expanding the operating range of the device during the metal dust collection operation, and can effectively improve the metal dust collection effect, and at the same time, through the fourth gear 22 and the third gear 21, and the second gear 20 and the first gear 19, through the force transmission between the gears, and then through the first motor 23 set with a small motor structure, the operation of driving the bellows 7 and the air inlet 8 to rotate at a uniform speed can be completed, which effectively reduces the volume and weight of the device.

[0040] The front end of the metal dust filter and collection chamber 1 is hinged with a sealing cover plate 24 through a hinge, and the interior of the sealing cover plate 24 is fixedly connected with tempered transparent glass, the lower part of the interior of the metal dust filter and collection chamber 1 is fixedly connected with a centrifugal fan 25, and the centrifugal fan 25 is composed of at least fan blades and a motor, the bottom end of the metal dust filter and collection chamber 1 is fixedly connected with a dustproof air intake net for gas circulation, and the bottom end of the metal dust filter and collection chamber 1 is symmetrically fixedly connected with a fixing frame, and the bottom end of the fixing frame is symmetrically fixedly connected with a universal wheel.

[0041] By means of the universal wheels, the device can be freely moved, and after reaching the working area, the device can be limited and fixed by locking the universal wheels. The centrifugal fan 25 is operated to generate centrifugal force, and the metal dust is filtered and collected in cooperation with the bellows 7 and the air inlet 8. At the same time, since the sealing cover plate 24 is fixedly connected with tempered transparent glass, the working conditions inside the metal dust filtering and collecting chamber 1 can be observed more intuitively.

[0042] An operating frame 26 is fixedly connected to the interior of the metal dust filtering and collecting chamber 1, and the inner walls on both sides of the operating frame 26 are symmetrically fixedly connected to the connecting chamber 27, and the inner top of the upper connecting chamber 27 and the inner bottom of the lower connecting chamber 27 are fixedly connected to the return spring 28, and one end of the return spring 28 is fixedly connected to one end of an extension block 29 movably connected to the interior of one end of the connecting chamber 27, and the end of the extension block 29 away from the return spring 28 is fixedly connected to one end of the connecting frame 30, and the inner walls on both sides of the connecting frame 30 are provided with a clamping groove 31, and the inside of the clamping groove 31 is clamped with a clamping block 32, and the clamping block 32 is symmetrically fixedly connected to the outer walls on both sides of the mounting frame 33, and the inner side wall of the clamping groove 31 and the outer side wall of the clamping block 32 are both "convex" structure settings, and the upper connecting frame 30 is fixedly connected to the interior of a metal screen 34, and the lower connecting frame 30 is fixedly connected to the interior of a dust bag 35.

[0043] By setting the metal screen 34 and the dust bag 35, the inhaled gas moves from top to bottom under the centrifugal force generated by the centrifugal fan 25, so that the metal screen 34 and the dust bag 35 are graded and filtered, and are collected inside the metal screen 34 and the dust bag 35 respectively, which is more convenient for subsequent screening and can effectively improve the recycling of metal dust. At the same time, the mounting frame 33 is clamped to the inside of the connecting frame 30 by the clamping block 32, so that the clamping fixing method is adopted, which is easier for subsequent maintenance and cleaning.

[0044] The inner walls on both sides of the working frame 26 are provided with rotating cavities for the rotating wheel 37 to move, and one side of the rotating wheel 37 is fixedly connected to one side of the cam block 36, and a linkage rod 38 is fixedly connected between the cam blocks 36, one side of one cam block 36 is fixedly connected to the output end of the second motor 39, and the second motor 39 is fixedly connected to the outer wall of the metal dust filtering and collecting chamber 1, and the output end of the second motor 39 passes through the outer wall of the metal dust filtering and collecting chamber 1 and the side wall of the working frame 26, and extends to the inside of the rotating cavity, and is fixedly connected to the corresponding side wall of the rotating wheel 37.

[0045] By setting up the second motor 39, during the process of the device filtering and collecting metal dust, the second motor 39 outputs the operation at a uniform speed, thereby driving the rotating wheel 37 to rotate at a uniform speed, and the two cam blocks 36 are fixed by the linkage rod 38, so that the two cam blocks 36 can both rotate. In this way, during the rotation of the two cam blocks 36, they will respectively contact the upper connected frame 30 and the lower connected frame 30, so that they move upward and downward respectively, and after the contact with the cam blocks 36 is released, they are reset by the reset spring 28, thereby realizing cyclic vibration operation, which helps to separate impurities attached to the metal screen 34 and the dust bag 35, so that the metal screen 34 can effectively avoid the problem of reduced filtration due to blockage, and improve the storage effect of the dust bag 35.

[0046] The specific use process of this embodiment is as follows:

[0047] First, before filtering and collecting metal dust, a preparation process is performed, specifically, the device can be freely moved by setting a universal wheel, and after reaching the working area, the device is limited and fixed by locking the universal wheel, and the bellows 7 is bent according to the use requirements, thereby changing the angle of the air inlet 8, so that the air inlet 8 can be flexibly adapted to the working area where metal dust is easily generated;

[0048] Secondly, the centrifugal fan 25 operates to generate centrifugal force, and cooperates with the bellows 7 and the air inlet 8 to perform metal dust filtering and collection operations. When the metal dust is generated in a wide range, the first motor 23 rotates at a uniform speed, thereby driving the fourth gear 22 fixedly connected to the output end to rotate at a uniform speed, thereby driving the meshing third gear 21 to rotate at a uniform speed, and because the top of the third gear 21 is fixedly connected to the second gear 20 through a transmission rod, the second gear 20 is linked to rotate synchronously, and because the outer wall of the second gear 20 is meshed with the outer wall of the first gear 19, the first gear 19 is finally driven to rotate at a uniform speed, and the bellows 7 and the air inlet 8 are rotated at a uniform speed, so that the surrounding air can be inhaled with the device as the center point;

[0049] Afterwards, the inhaled gas moves downward due to the centrifugal force generated by the centrifugal fan 25, and thus passes through the metal screen 34 and the dust bag 35 to complete graded filtration, and is collected inside the metal screen 34 and the dust bag 35 respectively;

[0050] Finally, the mounting frame 33 is clamped to the inside of the connecting frame 30 through the clamping block 32. This clamping fixing method is easier to maintain and clean later. The first connecting frame 3 and the second connecting frame 4 are covered on the outer wall of the air inlet port 2. The specific method is that the first connecting frame 3 and the second connecting frame 4 are clamped to each other, and the connecting cavity 15 opened at the bottom of the first connecting frame 3 and the second connecting frame 4 is clamped to the top outer wall of the connecting column 17, and the first magnetic suction piece 16 and the second magnetic suction piece 18 are magnetically attracted to each other. In this way, the quick-release fixing of the first connecting frame 3 and the second connecting frame 4 is completed. At the same time, the first connecting frame 3 and the second connecting frame 4 are clamped to each other. During the mutual snap-fit ​​assembly process, the vertical surfaces of the first connecting frame 3 and the second connecting frame 4 correspond to each other, so that the plug-in blocks 12 and the plug-in cavity 10 provided on the vertical surfaces of the first connecting frame 3 and the second connecting frame 4 also correspond to each other, so that the plug-in blocks 12 are all plugged into the interior of the plug-in cavity 10, and the first limiting protrusion 11 and the second limiting protrusion 14 are mutually abutted, thereby completing the limiting of the plug-in block 12, and also completing the mutual snap-fit ​​assembly of the first connecting frame 3 and the second connecting frame 4. In this way, when cleaning or maintaining the device, it is convenient to separate the first connecting frame 3 and the second connecting frame 4, and such a metal dust filtering and collecting device is ready for use;
