[0002] Anode carbon blocks refer to carbon blocks produced using petroleum coke and pitch coke as aggregates and coal tar pitch as a binder, used as anode materials in prebaked aluminum electrolytic cells. These carbon blocks have been roasted and have a stable geometric shape, hence the name prebaked anode carbon blocks. When processing and shaping anode carbon blocks, two evenly distributed grooves need to be opened, and the fine dust generated during the opening of the grooves can only be treated by dust removal.

[0003] Chinese Patent CN221496334U discloses a prebaked anode carbon block grooving dust collection device, comprising a workbench and a dust cover, the dust cover being installed on the top surface of the workbench; a dust collection box, fixedly installed on the top surface of the workbench; a fixed box, fixedly installed on the top surface of the dust collection box; a fixed plate, fixedly installed on the top surface of the fixed box; a drive mechanism, disposed on the fixed plate, used to generate negative pressure for dust suction; a dust collection mechanism, disposed on the dust cover, used to adsorb, transport, and collect dust; and a transmission mechanism connected to the drive mechanism. This prebaked anode carbon block grooving dust collection device can effectively recover dust within the area, solving the problem that dust in dead corners is difficult to collect due to airflow, ensuring dust collection effect and facilitating the grooving work of prebaked anode carbon blocks.

[0004] However, the above technical solution has the following shortcomings: when the device generates negative pressure by rotating the impeller, the impeller pushes the air outward toward one side of the rotating shaft, but one side of the rotating shaft is in a sealed state, which causes the dust conveying pipe to be unable to achieve negative pressure dust suction and cannot effectively absorb the dust generated during the forming of the anode carbon block. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a molding dust collection device that can efficiently absorb, transport, and collect the dust generated during the molding of anode carbon blocks, ensuring the practicality of the device.

[0006] The present invention provides a dust collection device, comprising a base and a suction mechanism. The base is provided with a dust cover and a collection box, and the collection box is provided with a mounting base. An air duct is provided inside the mounting base, and a first conveying pipe and a second conveying pipe are respectively connected to both ends of the air duct. The suction mechanism includes a fixed frame inside the air duct, a support cylinder on the fixed frame, a rotating shaft rotatably connected to the support cylinder, an impeller and a second gear coaxially mounted on the rotating shaft, a first motor mounted on the mounting base, a main shaft driven by the first motor, and a first gear coaxially mounted on the main shaft. The main shaft is rotatably connected to the mounting base, and the first and second gears are meshed. An isolation cover is provided outside the first and second gears, and both the rotating shaft and the main shaft are rotatably connected to the isolation cover.

[0007] Preferably, a limit ring is coaxially provided on the rotating shaft, and the limit ring is rotatably disposed inside the support cylinder.

[0010] Preferably, a fixing plate is provided at one end of the first conveying pipe and the second conveying pipe near the mounting base. The mounting base is provided with a mounting groove for the fixing plate to be embedded in. Multiple bolts are provided through the fixing plate, and the bolts are threadedly connected to the mounting base.

[0011] Preferably, a third conveying pipe is rotatably connected to the dust cover, a rotary joint is provided at the connection between the third conveying pipe and the second conveying pipe, a connecting frame is provided on the third conveying pipe, and multiple dust suction heads are provided on the connecting frame.

[0012] Preferably, the dust cover is provided with a drive assembly, which includes a second motor mounted on the dust cover, a third gear driven and connected to the second motor, and a fourth gear coaxially mounted on the third conveying pipe, wherein the third gear and the fourth gear are meshed together.

Detailed Implementation

[0022] Example 1

[0023] like Figures 1-4As shown in the figure, the dust collection device proposed in this embodiment includes a base 1 and a suction mechanism. A dust cover 2 and a collection box 3 are provided on the base 1. A mounting base 4 is provided on the collection box 3. An air duct is provided inside the mounting base 4. A first conveying pipe 17 and a second conveying pipe 18 are respectively connected to the two ends of the air duct. A fixing plate 19 is provided at one end of the first conveying pipe 17 and the second conveying pipe 18 near the mounting base 4. A mounting groove 21 is provided on the mounting base 4 for the fixing plate 19 to be embedded. A plurality of bolts 20 are provided through the fixing plate 19. The bolts 20 are threadedly connected to the mounting base 4. The first conveying pipe 17 and the second conveying pipe 18 are both used to convey dust. The collection box 3 is used to collect dust. The first conveying pipe 17 and the second conveying pipe 18 can be disassembled by the fixing plate 19 and the bolts 20 to facilitate the maintenance of the suction mechanism.

[0024] like Figure 2 As shown, the suction mechanism includes a fixed frame 5 installed inside the air duct, a support cylinder 6 installed on the fixed frame 5, a rotating shaft 7 rotatably connected to the support cylinder 6, an impeller 8 and a second gear 13 coaxially mounted on the rotating shaft 7, a first motor 10 installed on the mounting base 4, a main shaft 11 driven and connected to the first motor 10, and a first gear 12 coaxially mounted on the main shaft 11. The main shaft 11 is rotatably connected to the mounting base 4, and the first gear 12 and the second gear 13 are meshed. An isolation cover 14 is provided on the outside of the first gear 12 and the second gear 13. The rotating shaft 7 and the main shaft 11 are both rotatably connected to the isolation cover 14.

[0025] In this embodiment, when it is necessary to absorb and treat the dust generated during the processing of anode carbon blocks, the dust cover 2 is first placed around the processing area. Then, the first motor 10 is started to drive the main shaft 11 to rotate, so that the first gear 12 and the second gear 13 mesh and transmit power. Then, the second gear 13 drives the impeller 8 to rotate. The rotation of the impeller 8 in the air duct creates a pressure difference on both sides of the air duct, pushing the air into the collection box 3. This achieves the effect of accelerating the air flow by the wind generated by the difference between high pressure and low pressure. The isolation cover 14 can isolate the first gear 12 and the second gear 13, preventing dust from entering the meshing area of ​​the gears, which would lead to increased wear and reduced transmission efficiency. This has good practicality.

[0026] Example 2

[0027] like Figure 2As shown, in this embodiment of the dust collection device, compared with the first embodiment, a limiting ring 9 is coaxially arranged on the rotating shaft 7. The limiting ring 9 is rotatably arranged inside the support cylinder 6. The limiting ring 9 is used to limit the axial position of the rotating shaft 7 on the support cylinder 6 to ensure the stability of gear meshing. A stabilizing frame 16 is arranged on the fixed frame 5. The main shaft 11 and the stabilizing frame 16 are rotatably connected. The stabilizing frame 16 is used to improve the stability of the main shaft 11 when rotating. A sealing ring 15 is coaxially arranged on both the rotating shaft 7 and the main shaft 11. The sealing ring 15 is rotatably arranged inside the isolation cover 14. The sealing ring 15 is used to further improve the dust isolation effect of the isolation cover 14.

[0028] Example 3

[0029] like Figure 1 and Figure 4 As shown, in this embodiment of the dust collection device, compared with the first embodiment, a third conveying pipe 23 is rotatably connected to the dust cover 2. A rotary joint 24 is provided at the connection between the third conveying pipe 23 and the second conveying pipe 18. A connecting frame 25 is provided on the third conveying pipe 23. Multiple dust suction heads 26 are provided on the connecting frame 25. The rotary joint 24 is used to connect the third conveying pipe 23 and the second conveying pipe 18, while the third conveying pipe 23 can also rotate.

[0030] The dust cover 2 is equipped with a drive assembly, which includes a second motor 27 mounted on the dust cover 2, a third gear 28 driven by the second motor 27, and a fourth gear 29 coaxially mounted on the third conveying pipe 23. The third gear 28 and the fourth gear 29 are meshed together. The dust cover 2 is equipped with a top cover 22, and the drive assembly is located inside the top cover 22. Two retaining rings 30 are coaxially mounted on the third conveying pipe 23, which are distributed vertically. The two retaining rings 30 are respectively attached to the inner and outer surfaces of the dust cover 2 for mounting the third conveying pipe 23 on the dust cover 2.

[0031] In this embodiment, when a negative pressure channel is formed inside the conveying pipe assembly, the dust suction head 26 will suck up the dust generated during processing. After entering the connecting frame 25, the dust passes through the second conveying pipe 18, the air duct, the first conveying pipe 17 and the collection box 3 in sequence along the third conveying pipe 23. At the same time, the second motor 27 drives the third gear 28 to rotate, so that the third gear 28 and the fourth gear 29 mesh with the transmission mechanism. The fourth gear 29 drives the third conveying pipe 23 to rotate, and the third conveying pipe 23 drives the connecting frame 25 and the dust suction head 26 to rotate, so as to achieve all-round dust suction and ensure the efficiency and quality of dust collection.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto.
