Description

Technical Field

[0001] This utility model belongs to the technical field of slag removal equipment, specifically relating to an automatic slag removal device for a pulper. Background Technology

[0002] As a key piece of equipment in the waste paper recycling process, the pulper's core function is to break down waste paper raw materials into pulp. Currently, the pulping methods used in the paper industry suffer from low efficiency and low automation. Some paper companies still rely on manual labor with simple tools for pulping. This method is not only labor-intensive and creates a harsh working environment, but also poses significant safety hazards. Furthermore, the low efficiency of pulping cannot match the continuous production rhythm of the pulper. Some companies use semi-mechanized equipment such as rope winches, which can remove some long strips of impurities, but they are helpless when dealing with heavy, lumpy pulp. Moreover, the rope needs to be manually cut and cleaned after it gets tangled with impurities, making continuous pulping impossible. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing an automatic slag removal device for a pulper.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automatic slag removal device for a pulper, comprising a grab bucket support mounted on a base, a slag well assembly located below the base, a grab bucket body assembly connected to the grab bucket support, an electric hoist assembly connected to the grab bucket support at the upper end of the grab bucket body assembly, an electric hoist assembly that enables the grab bucket body assembly to move up and down along the direction of the slag well assembly, and an electric hoist assembly that enables the grab bucket body assembly to move along the length of the support at the upper end, a grab bucket hydraulic station connected to the grab bucket body assembly on one side of the electric hoist assembly, and a control assembly at one end of the grab bucket support.

[0005] In the aforementioned automatic slag removal device for a pulper, the grab bucket assembly includes a grab bucket drive frame. The upper end of the grab bucket drive frame has a lifting connection part, and the lower end has a grab bucket connection part. Several grab buckets are movably arranged circumferentially outside the grab bucket connection part. A grab bucket drive assembly is provided between the lifting connection part and the grab buckets, enabling the grab buckets to retract inwards or expand outwards. Integrating the grab buckets and their drive mechanism into a single, compact component facilitates installation, maintenance, and replacement. The clear distinction between the lifting connection part and the grab bucket connection part ensures that the lifting and grabbing functions do not interfere with each other, improving structural stability and reliability. Furthermore, the ability of the grab buckets to retract towards the center allows for better grabbing and holding of irregularly shaped slag, resulting in high grabbing efficiency and reduced spillage.

[0006] In the aforementioned automatic slag removal device for a pulper, the grab bucket drive assembly includes a grab bucket drive rod disposed between the grab bucket and the lifting connection. One end of the grab bucket drive rod is connected to the lifting connection, and the other end is connected to the end of the grab bucket near the grab bucket connection. The grab bucket drive rod is also connected to the grab bucket hydraulic station. Using a hydraulic system as a power source provides enormous clamping force, suitable for gripping heavy, dense slag blocks. Simultaneously, the linkage mechanism formed by the grab bucket drive rod converts the vertical movement of the lifting connection into the opening and closing movement of the grab bucket. This mechanical structure is simple, robust, and not easily damaged, ensuring a secure grip.

[0007] In the aforementioned automatic slag removal device for a pulper, the electric hoist assembly includes a drive housing. A rope drum is located inside the drive housing. Lifting ropes, connected to a lifting connection, are wound around the outer sides of both ends of the rope drum. A drive motor connected to the rope drum is located at one end of the drive housing, and a reducer connected to the rope drum is located at the other end. Integrating the drive motor, reducer, and rope drum within the drive housing results in a compact structure, good protection, and low operating noise. Furthermore, the lifting ropes wound around both ends of the rope drum work together to lift the grab bucket, ensuring stability and balanced force distribution during the lifting process, preventing tilting or swaying caused by single-point force. The drive motor, in conjunction with the reducer, provides stable and sufficient lifting torque, ensuring the safe lifting of a fully loaded grab bucket.

[0008] In the aforementioned automatic slag removal device for a pulper, the grab bucket support has a horizontally arranged guide rail, and several vertically arranged support columns are provided on the lower side of the guide rail, with the lower ends of the support columns fixed to the base. The support columns and the horizontal guide rail constitute a robust gantry structure, providing stable support and precise guidance for the entire moving and lifting system. Simultaneously, the horizontal guide rail ensures that the drive housing can move precisely in a straight line and accurately position itself above each slag well.

[0009] In the aforementioned automatic slag removal device for a pulper, the grab bucket hydraulic station has a hydraulic housing, which is located at the end of the drive housing near the reducer, and the hydraulic housing is connected to the drive housing via a connecting rod. Suspending the hydraulic housing to one side of the drive housing via the connecting rod fully utilizes lateral space, avoids occupying too much space at the top, and its position allows for a certain balance with the drive motor, optimizing the weight distribution of the entire moving component.

[0010] In the aforementioned automatic slag removal device for a pulper, the transverse drive assembly includes a drive roller mounted on the upper side of the drive housing near the drive motor and connected to a horizontal guide rail. An auxiliary drive roller, also connected to the horizontal guide rail, is located on the upper side of the drive housing near the reducer. Hydraulic auxiliary rollers, connected to the horizontal guide rail, are located on both sides of the upper end of the hydraulic housing. This multi-point support scheme, employing drive rollers, auxiliary drive rollers, and hydraulic auxiliary rollers, ensures extremely smooth movement of the heavy drive housing and hydraulic housing on the horizontal guide rail, eliminating the risk of jamming, shaking, or derailment. Simultaneously, the drive rollers provide the primary power, while the other rollers primarily serve a supporting and guiding function, ensuring reliable system operation.

[0011] In the aforementioned automatic slag removal device for a pulper, the control component includes a DCS housing located on the lower side of a support column at one end of the grab bucket bracket. The DCS housing is equipped with a control switch and a touch screen, and the drive motor, grab bucket hydraulic station, and drive rollers are all connected to the DCS housing.

[0012] In the aforementioned automatic slag removal device for a pulper, the slag well group comprises a sedimentation well, a washing well, and a discharge well arranged axially along one end of the grab bucket support near the control component to the other end.

[0013] In the aforementioned automatic slag removal device for a pulper, the inner diameters of the sedimentation well, washing well, and slag discharge well are all equal and 1800mm. The uniform inner diameter of the three wells means that the same grab bucket can operate continuously at all workstations without replacement or adjustment, greatly reducing waiting time between processes and achieving seamless connection from sedimentation and washing to slag discharge, significantly improving overall processing efficiency.

[0014] Compared with existing technologies, the advantages of this utility model are as follows.

[0015] 1. The grab bucket of this device can move along the horizontal guide rail through the lateral drive component and be lifted by the electric hoist to achieve seamless connection of the entire process of grabbing, cleaning and discharging slag. At the same time, the three actions are coordinated and connected, and accurately positioned to each slag well, eliminating human error and instability.

[0016] 2. The transverse drive assembly of this device adopts a scheme of one active drive roller and multiple auxiliary support rollers, which distributes the weight on multiple support points, ensuring that the heavy combination of electric hoist assembly and grab bucket hydraulic station can move smoothly and steadily, effectively preventing the risks of jamming, impact and derailment.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-3 As shown, an automatic slag removal device for a pulper includes a grab bucket support 11 mounted on a base 1. A slag well assembly 12 is located below the base 1. A grab bucket body assembly 2 is connected to the grab bucket support 11. An electric hoist assembly 3 is provided at the upper end of the grab bucket body assembly 2, which enables the grab bucket body assembly 2 to move up and down along the direction of the slag well assembly 12 and is connected to the grab bucket support 11. A transverse drive assembly 4 is provided at the upper end of the electric hoist assembly 3, which enables the grab bucket body assembly 2 to move along the length of the support. A grab bucket hydraulic station 5 is connected to one side of the electric hoist assembly 3 and is connected to the grab bucket body assembly 2. A control assembly 6 is provided at one end of the grab bucket support 11.

[0023] Combination Figure 2 and Figure 3 As shown, the grab bucket assembly 2 includes a grab bucket drive frame 21. The upper end of the grab bucket drive frame 21 has a lifting connection part 22, and the lower end has a grab bucket connection part 23. Several grab buckets 24 are movably arranged around the grab bucket connection part 23. A grab bucket drive assembly 25 is provided between the lifting connection part 22 and the grab buckets 24, allowing the grab buckets 24 to retract inwards or expand outwards. Integrating the grab buckets 24 and their drive mechanism into a single, compact assembly facilitates installation, maintenance, and replacement. The clear distinction between the lifting connection part 22 and the grab bucket connection part 23 ensures that the lifting and grabbing functions do not interfere with each other, improving structural stability and reliability. Furthermore, the grab buckets 24 can retract towards the center, better grabbing and holding irregularly shaped slag, resulting in high grabbing efficiency and reduced spillage.

[0024] The grab bucket drive assembly 25 includes a grab bucket drive rod 26 disposed between the grab bucket 24 and the lifting connection part 22. One end of the grab bucket drive rod 26 is connected to the lifting connection part 22, and the other end is connected to the end of the grab bucket 24 near the grab bucket connection part 23. The grab bucket drive rod 26 is also connected to the grab bucket hydraulic station 5. Using a hydraulic system as the power source, it can provide enormous clamping force, suitable for grabbing heavy, dense slag blocks. Simultaneously, the linkage mechanism formed by the grab bucket drive rod 26 converts the vertical movement of the lifting connection part 22 into the opening and closing movement of the grab bucket 24. This mechanical structure is simple, robust, and not easily damaged, ensuring a secure grip.

[0025] Specifically, the electric hoist assembly 3 includes a drive housing 31, with a rope drum 32 inside the drive housing 31. Lifting ropes 33, connected to the lifting connection part 22, are wound around the outer sides of both ends of the rope drum 32. A drive motor 34 connected to the rope drum 32 is located at one end of the drive housing 31, and a reducer 35 connected to the rope drum 32 is located at the other end. Integrating the drive motor 34, reducer 35, and rope drum 32 within the drive housing 31 results in a compact structure, good protection, and low operating noise. The lifting ropes 33 wound around both ends of the rope drum 32 work together to lift the grab bucket, ensuring stability and balanced force distribution during lifting, preventing tilting or swaying caused by single-point force. Furthermore, the drive motor 34, in conjunction with the reducer 35, provides stable and sufficient lifting torque, ensuring the safe lifting of a fully loaded grab bucket 24.

[0026] like Figure 1 As shown, the grab bucket support 11 has a horizontally arranged horizontal guide rail 13, and several vertically arranged support columns 14 are provided on the lower side of the horizontal guide rail 13, with the lower end of the support columns 14 fixed to the base 1. The support columns 14 and the horizontal guide rail 13 constitute a robust gantry structure, providing stable support and precise guidance for the entire moving and lifting system. At the same time, the horizontal guide rail 13 ensures that the drive housing 31 can move precisely in a straight line and be accurately positioned above each slag well.

[0027] like Figure 2 As shown, the grab hydraulic station 5 has a hydraulic housing 51, which is located at the end of the drive housing 31 near the reducer 35, and is connected to the drive housing 31 by a connecting rod 52. Suspending the hydraulic housing 51 on one side of the drive housing 31 via the connecting rod 52 makes full use of the lateral space, avoids occupying too much space at the top, and its position can achieve a certain balance with the drive motor 34, optimizing the weight distribution of the entire moving component.

[0028] The lateral drive assembly 4 includes a drive roller 41 located on the upper side of the drive housing 31 near the drive motor 34 and connected to the horizontal guide rail 13; a drive auxiliary roller 42 located on the upper side of the drive housing 31 near the reducer 35 and connected to the horizontal guide rail 13; and hydraulic auxiliary rollers 43 located on both sides of the upper end of the hydraulic housing 51 and connected to the horizontal guide rail 13. This multi-point support scheme, employing the drive roller 41, drive auxiliary roller 42, and hydraulic auxiliary roller 43, ensures extremely smooth movement of the heavy drive housing 31 and hydraulic housing 51 on the horizontal guide rail 13, eliminating the risk of jamming, shaking, or derailment. Simultaneously, the drive roller 41 provides the main force, while the other rollers primarily serve a supporting and guiding function, ensuring reliable system operation.

[0029] like Figure 1 As shown, the control component 6 includes a DCS housing located on the underside of the support column 14 at one end of the grab bucket bracket 11. The DCS housing is equipped with a control switch and a touch screen, and the drive motor 34, the grab bucket hydraulic station 5, and the drive roller 41 are all connected to the DCS housing.

[0030] The slag well group 12 includes a sedimentation well 15, a washing well 16, and a slag discharge well 17 arranged axially along the grab bucket support 11 from one end near the control component 6 to the other end.

[0031] Specifically, the inner diameters of the sedimentation well 15, the washing well 16, and the slag discharge well 17 are all equal and 1800mm. The uniform inner diameter of the three wells means that the same grab bucket 24 can operate continuously at all workstations without replacement or adjustment, greatly reducing the waiting time between processes and achieving seamless connection from sedimentation and washing to slag discharge, thus significantly improving the overall processing efficiency.

[0032] The principle of this embodiment is as follows: Control component 6 controls the drive roller 41 of the horizontal drive component 4. The drive roller 41 rotates, driving the entire electric hoist component 3, the grab bucket hydraulic station 5, and the grab bucket body component 2 suspended below it to move along the horizontal guide rail 13 until it stops accurately above the slag well 15. The drive motor 34 of the electric hoist component 3 starts, reducing the speed and increasing the torque through the reducer 35, driving the rope drum 32 to rotate and releasing the lifting rope 33. The grab bucket body component 2 descends vertically under the action of gravity, penetrating into the slag in the slag well 15. After the grab bucket 24 inserts into the slag, the grab bucket hydraulic station 5 operates, providing hydraulic power to the grab bucket drive rod 26. The drive rod 26 moves, pushing several grab buckets 24 to retract inward around the grab bucket connection part 23, firmly grabbing the slag in the center of the grab bucket 24. After the grabbing action is completed, the drive motor 34 of the electric hoist component 3 reverses, retracting the lifting rope 33 through the drum, and fully loading the slag. The grab bucket assembly 2 of the slag is vertically lifted from the settling well 15. After being lifted to a predetermined height, the lateral drive assembly 4 is activated again, moving horizontally with the fully loaded grab bucket 24 away from the settling well 15 and heading to the washing well 16. The grab bucket 24 stops after moving directly above the washing well 16, and then the electric hoist assembly 3 descends again, immersing the grab bucket 24 into the washing well 16. After washing, the grab bucket 24 is lifted again, but it may not be fully lifted to the highest point. Instead, it pauses briefly above the well opening to allow the slag in the grab bucket 24 to drain, reducing the amount of water carried away. After draining, the lateral drive assembly 4 is activated for the last time, transporting the grab bucket 24 directly above the slag discharge well 17. After reaching the slag discharge well 17, the grab bucket hydraulic station 5 reverses its operation, pulling the grab bucket 24 outward through the grab bucket drive rod 26. The grabbed and washed slag falls into the slag discharge well 17 under gravity, completing the final unloading.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0034] Although this document frequently uses terms such as base 1, grab bucket support 11, slag well assembly 12, horizontal guide rail 13, support column 14, sedimentation well 15, washing well 16, slag discharge well 17, grab bucket body assembly 2, grab bucket drive frame 21, lifting connection part 22, grab bucket connection part 23, grab bucket 24, grab bucket drive assembly 25, grab bucket drive rod 26, electric hoist assembly 3, drive housing 31, rope drum 32, lifting rope 33, drive motor 34, reducer 35, lateral drive assembly 4, drive roller 41, drive auxiliary roller 42, hydraulic auxiliary roller 43, grab bucket hydraulic station 5, hydraulic housing 51, connecting rod 52, and control assembly 6, the possibility of using other terms is not excluded.
