[0018] 1. When metal dust enters the processing box in the present invention, the motor drives the connecting piece to rotate, thereby realizing the rotation of the first electromagnetic block and the second electromagnetic block. When the connecting piece rotates clockwise, the two contact switches installed on its surface will simultaneously contact the contact ball. When contacting, the first electromagnetic block is energized and the second electromagnetic block is de-energized. When the first electromagnetic block is energized, the metal dust can be adsorbed to prevent the metal dust from filling the inside of the processing box. When rotating 90 degrees, the intermittent gear meshes with the driving gear, causing the driving gear to rotate 90 degrees, and then driving the valve core plate to rotate 90 degrees through the second rotating shaft to close the hollow pipe. At this time, the first electromagnetic block and the second electromagnetic block continue to rotate until they rotate to 180 degrees, and the two contact switches contact the contact ball again, realizing the power-off of the first electromagnetic block and the power-on of the second electromagnetic block. At this time, the first electromagnetic block that rotates to the lower part can discharge the adsorbed metal dust through the material discharging port into the collection barrel for collection, preventing the dust from being directly adsorbed by the blower and causing damage to the blower, and improving the protection effect of the blower.

[0019] 2. While the connecting piece drives the first electromagnetic block and the second electromagnetic block to rotate in the present invention, the second rotating rod rotates simultaneously, thereby driving the extrusion blades to rotate. Through the rotation of the extrusion blades, the filter plate can be reciprocally knocked. With the cooperation of the spring, the metal dust adhering to the filter plate due to the failure of the electromagnetic block to adsorb in time can be lifted, and thus can be adsorbed by the electromagnetic block again, keeping the filter plate unobstructed. The filter plate can further improve the protection effect on the fan.

[0020] 3. In the present invention, through the rotational cooperation of the intermittent gear and the driving gear, and driving the valve core plate to rotate, the hollow tube is opened, so as to cooperate with the intermittently energized first electromagnetic block and second electromagnetic block to adsorb the metal dust. The hollow tube with an intermittent switch can compensate for the magnetic force error existing when the first electromagnetic block and the second electromagnetic block rotate, preventing the metal dust from falling into the treatment box during the magnetic force intermittent difference, thereby increasing the concentration of metal dust inside the treatment box and affecting the collection effect.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-6 , the embodiments provided by the present invention:

[0031] An occupational disease prevention and control device for metal dust includes a plurality of support frames 1. The inner walls of the plurality of support frames 1 are fixedly connected to the same collection bucket 2. The upper surface of the collection bucket 2 is fixedly connected to a mounting plate 3. The upper surface of the mounting plate 3 is fixedly connected to a processing box 4. A dust collection assembly and an auxiliary collection assembly are respectively arranged on the inner wall of the processing box 4.

[0032] The dust collection assembly includes a connecting piece 16 rotatably connected to the inner wall of the processing box 4. A first electromagnetic block 15 and a second electromagnetic block 17 are respectively fixedly installed on both sides of the connecting piece 16. Contact switches 35 are installed at both ends of the connecting piece 16. The two contact switches 35 are electrically connected between the first electromagnetic block 15 and the second electromagnetic block 17. The inner bottom wall of the processing box 4 is fixedly connected to a support block 28. Vertical plates 36 are fixedly installed on the upper surface of the support block 28 and on one inner wall of the processing box 4. Contact balls 37 are fixedly connected to the opposite surfaces of the two vertical plates 36. The upper surface of the processing box 4 is respectively fixedly connected to a fixing frame 5 and a fixing plate 18. The inner wall of the fixing frame 5 is fixedly connected to a hollow tube 6. The bottom end of the hollow tube 6 is fixedly communicated with the inner wall of the processing box 4. One side of the fixing plate 18 is rotatably connected to an intermittent gear 20 and a driving gear 22 through a first rotating shaft 19 and a second rotating shaft 21 respectively. One end of the second rotating shaft 21 penetrates through the surface of the hollow tube 6 and is fixedly connected to a valve core plate 23. A spiral blade 24 is fixedly connected to the inner wall of the hollow tube 6 through a limiting frame.

[0033] Based on the above structure, the adsorption surfaces of electromagnetic block 15 and electromagnetic block 2 17 are provided with depressions, which can increase the time that metal dust stays on the surface of electromagnetic block 15 and electromagnetic block 2 17 and improve the adsorption effect. The resistance switch 35 is a prior art, and its main feature is that it can change its state when subjected to a specific resistance force or pressure, thereby connecting or disconnecting the circuit. Through the set spiral blades 24, when a negative pressure environment is presented inside the processing box 4, the dust can pass through the trajectory of the spiral blades 24 and maintain the downward spiral process, which can avoid the dust from being dispersed when entering the processing box 4. The intermittent gear 20 rotates synchronously with the connecting piece 16.

[0034] like Figure 3 and 4 As shown, one side of the processing box 4 and one side of the fixed plate 18 are both rotatably connected to a pulley 13 through a rotating shaft 19, and the same belt 14 is overlapped on the surfaces of the two pulleys 13. The belt 14 is connected through the two pulleys 13 for transmission. A motor 12 is fixedly installed on one side of the processing box 4, and the output end of the motor 12 is coaxially installed with one end of the rotating shaft 19. The rotation of the rotating shaft 19 can be realized by the drive of the motor 12, which in turn drives the rotation of the pulley 13, thereby realizing the transmission of the belt 14, and making the connecting member 16 and the intermittent gear 20 rotate synchronously.

[0035] like Figure 3 and 5 As shown, the auxiliary collection assembly includes a plurality of springs 26 fixedly connected to the inner wall of one side of the processing box 4. Four springs 26 are provided to realize the vibration of the filter plate 27. One end of the plurality of springs 26 away from the inner wall of the processing box 4 is fixedly connected to the same filter plate 27. The surface of the filter plate 27 slides with the inner wall of the processing box 4. The filter plate 27 can block the metal dust inside the processing box 4 from the fan 25.

[0036] The inner wall of the processing box 4 is rotatably connected to a rotating rod 32, and the surface of the rotating rod 32 is fixedly connected to an extrusion blade 38 through a rotating drum. The surfaces of the rotating rod 32 and the rotating shaft 19 are both fixedly connected to a pulley 2 33. The extrusion blade 38 rotates reciprocatingly to extrude the filter plate 27, and the vibration of the filter plate 27 can be achieved by cooperating with the action of the spring 26.

[0037] The surfaces of the two pulleys 33 are overlapped with the same belt 34 , and the belt 34 is transmission-connected to the pulley 33 fixedly connected to the surface of the rotating rod 32 and the pulley 33 fixedly connected to the rotating shaft 19 .

[0038] like Figure 6As shown, a chute 29 is provided on one side of the support block 28. Two reset springs 30 are fixedly connected to the inner wall of the chute 29. One end of the two reset springs 30 away from the inner wall of the chute 29 is fixedly connected to the same trapezoidal scraper 31. The surface of the trapezoidal scraper 31 is slidably connected to the inner wall of the chute 29. By providing the reset springs 30 and the trapezoidal scraper 31, it is possible to scrape and discharge the electromagnetic block after power-off, improve the discharging effect, and at the same time, achieve self-adaptive fitting with the surface of the electromagnetic block.

[0039] As Figure 1 and 2 shown, a material discharging port 9 is provided on the upper surface of the mounting plate 3. A blower 25 is fixedly installed on the upper surface of the mounting plate 3. The output end of the blower 25 is fixedly communicated with one side of the processing box 4.

[0040] A water adding pipe 10 is fixedly communicated with the surface of the collection bucket 2. A slag discharging pipe 11 is fixedly communicated with the bottom end of the collection bucket 2. A control valve is fixedly installed on the surface of the slag discharging pipe 11. By filling water into the collection bucket 2, it is possible to prevent the collected dust from being lifted inside the collection bucket 2 and causing the dust to flow back from the material discharging port 9.

[0041] Two lower air pipes 7 and an upper air pipe 8 are respectively fixedly communicated with the surface of the hollow pipe 6. A plurality of suction heads are fixedly communicated with the surfaces of the two lower air pipes 7 and the upper air pipe 8. By using the lower air pipes 7 and the upper air pipe 8 with different lengths, the adsorption area can be increased.

[0042] The two lower air pipes 7 and the upper air pipe 8 are symmetrically distributed on the surface of the hollow pipe 6.

[0043] Working principle: When in use, first place the device body at the processing location of metal products. Fill the inside of the collection bucket 2 with water through the water filling port. Then start the fan 25 and the motor 12. The fan 25 can create a negative pressure environment inside the processing box 4, so that the hollow tube 6, the lower air duct 7, and the upper air duct 8 fixedly connected to the processing box 4 generate negative pressure to suck the external air containing metal dust into the processing box 4 for collection. When the metal dust enters the processing box 4, the motor 12 drives the connecting piece 16 to rotate, thus realizing the rotation of the first electromagnetic block 15 and the second electromagnetic block 17. When the connecting piece 16 rotates clockwise, the two contact switches 35 installed on its surface will simultaneously contact the contact ball 37. When contacting, the first electromagnetic block 15 is powered on and the second electromagnetic block 17 is powered off. When the first electromagnetic block 15 is powered on, it can adsorb the metal dust to prevent the processing box 4 from being filled with metal dust. When rotating 90 degrees, the intermittent gear 20 meshes with the driving gear 22, causing the driving gear 22 to rotate 90 degrees. Then, through the second rotating shaft 21, the valve core plate 23 is driven to rotate 90 degrees to close the hollow tube 6. At this time, the first electromagnetic block 15 and the second electromagnetic block 17 continue to rotate until they rotate to 180 degrees, and the two contact switches 35 contact the contact ball 37 again, realizing the power-off of the first electromagnetic block 15 and the power-on of the second electromagnetic block 17. At this time, the first electromagnetic block 15 that has rotated to the lower part can discharge the adsorbed metal dust through the discharge port 9 into the collection bucket 2 for collection. When discharging through the discharge port 9, the self-adaptive scraping of the surfaces of the first electromagnetic block 15 and the second electromagnetic block 17 can be realized through the arranged reset spring 30 and the trapezoidal scraping plate 31, improving the discharging effect and preventing the metal dust from being adsorbed by the fan 25 and causing damage to the fan 25. When rotating to 180 degrees, the intermittent gear 20 meshes with the driving gear 22 again and drives the valve core plate 23 to rotate to open the hollow tube 6, so as to cooperate with the powered-on second electromagnetic block 17 to adsorb the metal dust. The hollow tube 6 with an intermittent switch can compensate for the magnetic force error existing during the rotation of the first electromagnetic block 15 and the second electromagnetic block 17, preventing the metal dust from falling onto the contact switch 35 on the connecting piece 16 and causing damage to the contact switch 35;

[0044] While the connecting piece 16 drives the first electromagnetic block 15 and the second electromagnetic block 17 to rotate, the second rotating rod 32 rotates simultaneously, and then drives the extrusion blade 38 to rotate. Through the rotation of the extrusion blade 38, the filter plate 27 can be reciprocally knocked. The filter plate 27, in cooperation with the spring 26, can lift the metal dust adhering to the filter plate 27 due to the failure of the electromagnetic block to adsorb in time, so that it can be adsorbed by the electromagnetic block again, keeping the filter plate 27 unobstructed. The filter plate 27 can further improve the protection effect on the fan 25.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
