[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figures 1-3 As shown, a fly ash bagging device includes a support 1. A feeding hopper 3 and a pressure equalization pipe 8 are mounted on the support 1 via a mounting bracket 2. The upper part of the feeding hopper 3 is connected to a feeding pipe 6, and the lower part of the feeding hopper 3 is connected to a discharging pipe 4. A knife gate valve 5 is provided at the connection between the feeding hopper 3 and the discharging pipe 4. The lower end of the pressure equalization pipe 8 extends into the discharging pipe 4, and the upper end of the pressure equalization pipe 8 is connected to a bag filter dust collector. A sealing mechanism 9 is provided on the support 1 at the position corresponding to the position of the discharging pipe 4.
[0022] This device also includes a mobile cart on which a ton bag 13 is placed. A sealing mechanism 9 is used to seal the opening of the ton bag 13 with the discharge pipe 4. Fly ash enters the discharge hopper 3 through the feed pipe 6. The mobile cart transports the ton bag 13 to below the discharge pipe 4. Under the action of the sealing mechanism 9, the opening of the ton bag 13 is tightly fitted to the outer periphery of the discharge pipe 4, while the rest of the opening of the ton bag 13 is also fitted to each other, achieving a sealed opening of the ton bag 13. The knife gate valve 5 is opened, allowing the fly ash in the discharge hopper 3 to enter the ton bag 13 through the discharge pipe 4. Because the opening of the ton bag 13 is sealed, fly ash is prevented from flying out of the bag opening, effectively preventing dust pollution.
[0023] The pressure equalization pipe 8 is located inside the discharge pipe 4, and one end of it enters the ton bag 13. This allows the ton bag 13 to maintain a slight negative pressure, which further helps to prevent dust.
[0024] A vibration motor 7 is installed on the outside of the hopper 3. When the vibration motor 7 is running, it generates vibration, which allows the fly ash on the side wall of the hopper 3 to be discharged more effectively.
[0025] The sealing mechanism 9 includes a clamping part 19, which includes a protrusion 20 corresponding to the outline of the discharge pipe 4. The protrusion 20 protrudes away from the discharge pipe 4. The part of the clamping part 19 other than the protrusion 20 is planar. A clamping strip 21 is installed on the side of the clamping part 19 near the discharge pipe 4. The clamping strip 21 is arranged along the side wall of the clamping part 19. The sealing mechanism 9 also includes a clamping block 22 and a pressure block 24 disposed opposite to the clamping part 19. The clamping block 22 corresponds to the discharge pipe 4. The position of the tube 4 is determined by the clamping block 22, which is positioned according to the contour of the discharge tube 4. Two pressure blocks 24 are provided, located on either side of the clamping block 22. The pressure blocks 24 are planar structures. A second clamping strip 23 is provided on the side of the clamping block 22 closest to the discharge tube 4, and a third clamping strip 25 is provided on the side of the pressure block 24 closest to the discharge tube 4. The first clamping strip 21, the second clamping strip 23, and the third clamping strip 25 are at the same height and are made of rubber. The device also includes a drive mechanism that can drive the clamping part 19, the clamping block 22, and the pressure block 24 to move. The drive mechanism includes a linear actuator 16, a mounting rod 15 on a bracket 1, and the linear actuator 16 fixedly mounted on the mounting rod 15. The linear actuator 16 drives a support block 17, and several connecting rods 18 connect the support block 17 and the clamping part 19. The drive mechanism also includes a second linear actuator 26 and a third linear actuator 27. The second linear actuator 26 drives a clamping block 22, and the third linear actuator 27 drives a pressure block 24. A second mounting rod 28 is provided on the bracket 1, and the second linear actuator 26 and the third linear actuator 27 are fixedly mounted on the second mounting rod 28. The linear actuators 16, 26, and 27 can be cylinders, hydraulic rods, or electric push rods.
[0026] After the support plate 10 moves the ton bag 13 to below the discharge hopper 3, it opens the bag opening of the ton bag 13, allowing it to pass through the gap between the discharge pipe 4 and the clamping strips 21, 23, and 24, thus covering the discharge pipe 4. The linear actuator 16 drives the support block 17 to move the clamping part 19 towards the discharge pipe 4, pressing one side of the ton bag 13 onto the discharge pipe 4 via the clamping strips 21, while simultaneously supporting the remaining part of the bag opening on that side. Then, the linear actuator 26 drives the clamping block 22 to move, causing the clamping block 22 to push the other side of the ton bag 13 onto the discharge pipe 4 via the clamping strips 23, thus ensuring that the bag opening of the ton bag 13 covers the outer periphery of the discharge pipe 4 without any gaps. Linear actuator 27 then drives the pressure block 24 to move toward the clamping part 19. The clamping bar 25 pushes the bag opening on one side of the ton bag 13 to the other side. Finally, the clamping bar 21 and clamping bar 25 work together to clamp the bag openings on both sides of the ton bag 13, making the bag openings on both sides fit together and seal. This achieves a seal between the bag opening of the ton bag 13 and the discharge pipe 4, as well as between the bag opening of the ton bag 13 itself, thereby effectively preventing dust.
[0027] The end of the pressure block 24 near the clamping block 22 can fit against the side of the clamping block 22, so that the clamping strip 3 25 and the clamping strip 23 can contact each other, thereby achieving effective clamping of the bag opening of the ton bag 13 without gaps.
[0028] A guide rod 30 is connected to the side of the support block 17 away from the clamping part 19. A guide sleeve 29 is installed on the mounting rod 15, and the guide rod 30 passes through the guide sleeve 29. The cooperation between the guide sleeve 29 and the guide rod 30 can guide the movement of the support block 17 and support the support block 17 to prevent it from tilting downwards due to its own weight.
[0029] Limiting strips 31 are provided on both sides of the guide rod 30, and grooves that cooperate with the limiting strips 31 are provided on the guide sleeve 29, which can further limit the deflection of the guide rod 30 during its movement.
[0030] The device also includes a guide rail 12, one end of which extends below the discharge hopper 3. The moving vehicle includes a support plate 10, and a moving wheel 11 is provided at the lower part of the support plate 10. The moving wheel 11 is rolled on the guide rail 12. The moving wheel 11 is equipped with a brake, which can stop after reaching below the discharge hopper 3, so that the moving vehicle is fixed in position during the fly ash bagging process. The guide rail 12 is used to guide the moving wheel 11 and guide the moving vehicle to below the discharge hopper 3.
[0031] A connecting buckle 33 is installed on the outer periphery of the ton bag 13. A fixing frame 14 is installed on the support plate 10 on both sides of the ton bag 13. A hook 32 is installed on the fixing frame 14, and the hook 32 can be inserted into the connecting buckle 33. By hooking the connecting buckle 33 with the hook 32, the ton bag 13 is opened, which can more effectively receive materials.
[0032] When the ton bag 13 is empty, the connecting buckle 33 can be easily moved and can be easily fitted onto the hook 32. When the ton bag 13 is full of fly ash, the expansion of the ton bag 13 makes it difficult for the connecting buckle 33 to move and not easily detach from the hook 32. It is necessary to allow the hook 32 to move so that it can be easily inserted into or detached from the connecting buckle 33. Figure 4 , Figure 5 As shown, a mounting block 39 is connected to the inner side of the fixing frame 14, and a hook 32 is slidably mounted on the mounting block 39. A spring 38 is provided between the hook 32 and the mounting block 39. The hook 32 includes two side frames 34, and end plates 35 are connected to the upper and lower ends of the two side frames 34. A sliding groove 36 is opened on the inner side of the side frame 34. Sliding blocks 37 are connected to both sides of the mounting block 39 and are disposed in the sliding groove 36. One end of the spring 38 is fixed to the upper end face of the mounting block 39, and the other end of the spring 38 is fixed to the lower end face of the upper end plate 35. Under the cooperation of the sliding groove 36 and the sliding block 37, the hook 32 can move vertically on the mounting block 39, while restricting the movement of the hook 32 in other directions. When the hook 32 needs to be inserted into the connecting buckle 33, press the hook 32 down, then pull the connecting buckle 33 to the position where the hook 32 is. Release the hook 32, and the hook 32 will move upward under the action of the spring 38, thus inserting into the connecting buckle 33 from bottom to top. When the connecting buckle 33 needs to be removed from the hook 32, press the hook 32 down, causing the hook 32 to descend, and the connecting buckle 33 can then disengage from the hook 32.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
