Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0055] For the sludge treatment and loading system of this invention, please refer to [link / reference]. Figure 1 and Figure 2As shown, the system includes a dewatering mechanism 1, a conveying mechanism 2, and a sludge unloading mechanism 3. These three mechanisms are interconnected in operation, with the conveying mechanism 2 connecting the dewatering mechanism 1 and the sludge unloading mechanism 3. During sludge treatment, storage, and loading operations, the dewatering mechanism 1 dewaters the sludge, and the conveying mechanism 2 transfers the dewatered sludge from the dewatering mechanism 1 to the sludge unloading mechanism 3. The sludge unloading mechanism 3 then unloads the sludge onto a truck 5, which finally transports the sludge.

[0056] In a preferred embodiment, the dewatering mechanism 1 includes a dewatering frame 12 and a dewatering machine 11 mounted on the dewatering frame 12. Optionally, the dewatering machine 11 may specifically include a filter press, such as one that can dewater sludge by pressing.

[0057] Please see below. Figure 3a and Figure 3b As shown, the dewatering frame 12 is an open frame structure. The bottom of the dewatering frame 12 is fixedly mounted on the foundation surface 4, and the dewatering frame 12 has a suspended dewatering machine mounting platform. Furthermore, a feed inlet 121 inclined to one side is provided at the bottom of the dewatering machine mounting platform. When sludge falls onto the feed inlet 121, it will automatically slide to the outlet for discharge under gravity. Optionally, the dewatering machine 11 is fixedly mounted on the dewatering frame 12 with bolts. Please refer to [link to relevant documentation]. Figure 4a and Figure 4b As shown, the dewatering machine 11 is specifically installed on the dewatering machine mounting platform of the dewatering machine frame 12, and the outlet of the dewatering machine 11 is connected to the discharge port 121, so that the sludge after dewatering by the dewatering machine 11 can be directly discharged into the discharge port 121.

[0058] In addition, a canopy 15 is provided on the top of the dewatering machine frame 12 to shield and protect the dewatering machine 11 installed on the dewatering machine mounting platform of the dewatering machine frame 12, so as to prevent the dewatering machine 11 from being exposed to the sun or wind and rain when performing sludge treatment operations in the outdoor environment, thus ensuring the service life and safety of the dewatering machine 12.

[0059] The conveying mechanism 2 includes a conveying track, a sludge storage trolley 23, and a conveying drive component 24. The conveying track connects the dewatering mechanism 1 and the sludge unloading mechanism 3. One end of the conveying track connects to the dewatering mechanism 1, specifically below the discharge port 121 of the dewatering frame 12, and the other end connects to the sludge unloading mechanism 3. The sludge storage trolley 23 is mounted on the conveying track and is driven by the conveying drive component 24 to slide back and forth between the dewatering mechanism 1 and the sludge unloading mechanism 3.

[0060] When sludge treatment, storage and loading operations are carried out, the conveying drive 24 drives the sludge storage trolley 23 to move below the discharge port 121. The sludge dewatered by the dewatering machine 11 falls directly from the discharge port 121 and onto the sludge storage trolley 23. Then, the conveying drive 24 drives the sludge storage trolley 23 in the opposite direction to slide and transfer it to the sludge unloading mechanism 3 for unloading and loading.

[0061] In a preferred embodiment, in the sludge treatment loading system of the present invention, the sludge unloading mechanism 3 is a tilting sludge unloading mechanism. When the sludge storage trolley 23 carrying sludge slides onto the sludge unloading mechanism 3, the tilting sludge unloading mechanism 3 can drive the sludge storage trolley 23 to tilt, causing the sludge on the trolley 23 to pour out, thus achieving complete sludge unloading.

[0062] Please see again. Figure 1 and Figure 2 As shown, the tilting sludge unloading mechanism 3 includes a tilting frame 31. Specifically, the tilting frame 31 is a gantry structure, with its bottom movably mounted on the foundation surface 4, and its top driven by a tilting hydraulic cylinder 32 to rotate around a movably mounted fulcrum, thereby tilting the frame 31. When the sludge storage trolley 23 is transferred to the unloading mechanism 3, it is specifically transferred to one end of the top of the tilting frame 31, and the sludge storage trolley 23 can dump sludge as the tilting frame 31 tilts. Optionally, after the gantry frame of the tilting frame 31 tilts and rises to its position, the bottom can accommodate a sludge transport truck 5 to drive through, allowing the truck 5 to directly enter and load sludge.

[0063] Furthermore, the conveying track includes a first track 21 and a second track 22. The first track 21 is located near and connected to the dewatering mechanism 1, specifically extending into the bottom of the dewatering frame 12 and reaching the corresponding discharge port 121. The second track 22 is located on the tilting frame 31, and is connected to the tilting frame 31 when it is not tilted. Thus, after the sludge storage trolley 23 is loaded with sludge from the dewatering mechanism 1, it can be driven by the conveying drive component 24 to slide from the first track 21 to the second track 22, thereby transferring it to the sludge unloading mechanism 3.

[0064] Specifically, the first track 21 and the second track 22, after being connected, form a straight track that is completely aligned from left to right. Optionally, the conveying drive component 24 is specifically a linear hydraulic cylinder, whose output is linear telescopic transmission, and is specifically located below the dehydrator frame 12. Please refer to [further details omitted]. Figure 5 As shown, a movable joint 26 is provided on the output end of the conveying drive component 24, and a movable clamp 25 is provided on the sludge storage trolley 23, specifically on the side near the dewatering mechanism 1. The movable clamp 25 can be radially engaged into the movable joint 26, and the movable clamp 25 and the movable joint 26 are relatively fixed in the axial direction after being engaged.

[0065] Thus, when the sludge storage trolley 23 descends into position with the tilting frame 31, the movable locking member 25 engages with the movable joint 26, and the output end of the conveying drive member 24 can extend or retract to drive the sludge storage trolley 23 to slide on the first track 21 and the second track 22, thereby dragging the sludge storage trolley 23 to slide to the corresponding discharge port 121 or pushing the sludge storage trolley 23 to slide onto the tilting frame 31; while when the sludge storage trolley 23 rises with the tilting frame 31, the movable locking member 25 and the movable joint 26 automatically disengage, so that the tilting and unloading of the sludge storage trolley 23 is not affected.

[0066] In the preferred embodiment, please refer again. Figure 1 and Figure 2 As shown, a locking strip 35 is provided on the tilting frame 31, and a locking groove 29 is provided on the mud storage trolley 23. When the mud storage trolley 23 is transferred to the tilting frame 31, the locking strip 35 can slide into and engage with the locking groove 29 to prevent the mud storage trolley 23 from detaching from the tilting frame 31 when the tilting frame 31 is tilted.

[0067] Specifically, the locking strip 35 is a long strip with the same orientation as the second track 22 and located on the outside of the second track 22. The locking groove 29 is a groove adapted to the locking strip 35, and the locking groove 29 is distributed on the front and rear sides of the mud storage trolley 23, with the locking strip 35 correspondingly distributed on the front and rear sides of the mud storage trolley 23. Thus, when the mud storage trolley 23 is transferred to the tilting frame 31, the locking strip 35 and the locking groove 29 engage, preventing the mud storage trolley 23 from detaching upward relative to the tilting frame 31. When the mud storage trolley 23 is tilted with the tilting frame 31, the engaging locking groove 29 and locking strip 35 on the front and rear sides keep the mud storage trolley 23 stable on the tilting frame 31 and prevent it from detaching.

[0068] In another preferred embodiment, a check valve assembly 36 is provided on the side of the tilting frame 31 closest to the first track 21. When the mud storage trolley 23 is transferred to the first track 21 and positioned on the tilting frame 31, as the tilting frame 31 enters the tilting process, the check valve assembly 36 can limit and prevent the mud storage trolley 23 from detaching from the tilting frame 31.

[0069] For details, please see Figure 6As shown, the check valve assembly 36 includes a gas spring 361 and a check valve plate 362. The middle portion of the check valve plate 362 is movably connected to the tilting frame 31. In its natural extended state, the gas spring 361 is connected at one end to the tilting frame 31 and at the other end to one end of the check valve plate 362. When the gas spring 361 is extended, both ends of the check valve plate 362 can rotate to protrude beyond the plane of the tilting frame 31, and the end of the check valve plate 362 furthest from the gas spring 361 prevents backflow onto the mud storage trolley 23.

[0070] During sludge treatment operations, in the sludge loading and transfer transport state, the tilting frame 31 is placed flat on the foundation base 4 and in contact with the surface of the foundation base 4. The end of the check plate 362 connected to the gas spring 361 abuts against the foundation base 4 and drives the gas spring 361 to retract. The other end of the check plate 362 retracts into the plane where the tilting frame 31 is located. The sludge storage trolley 23 can slide back and forth between the first track 21 and the second track 22 without restriction. When entering the tilting and unloading state, the tilting frame 31 enters the tilting process. The end of the check plate 362 connected to the gas spring 361 returns to the free state. At this time, the gas spring 361 extends normally and drives both ends of the check plate 362 to rotate and protrude into the plane where the tilting frame 31 is located. The end away from the gas spring 361 restricts the movement of the sludge storage trolley 23 out of the second track 22, thereby achieving the anti-return effect on the sludge storage trolley 23 on the second track 22.

[0071] For further details, please refer to [link / reference]. Figure 6 As shown, a limiting plate 363 and a limiting post 364 are also provided on the tilting frame 31. The check plate 362 is limited on the tilting frame 31 by the limiting plate 363 and its travel is limited by the limiting post 364.

[0072] Please see Figure 7 As shown, a front door 231 is provided on the sludge storage trolley 23. The front door 231 can be opened under its own gravity, so that the sludge can be automatically dumped when the tilting frame 31 is tilted.

[0073] Specifically, the front door 231 is a bucket-type gravity-operated self-opening door. The mud storage trolley 23 has a front door adapted to the front door 231. The lower end of the door is movably connected to both sides of the front door of the mud storage trolley 23, while the upper end of the door can move freely without restriction. Thus, when the mud storage trolley 23 is tilted, the upper end of the front door 231, without restriction, can rotate around its lower movable fulcrum under its own gravity, thereby achieving automatic opening.

[0074] In a preferred embodiment, please refer to Figure 7 and Figure 8 As shown, the mud storage trolley 23 is equipped with a front door lock assembly 27. The front door lock assembly 27 includes a first locking rod 271, a lock cylinder 272, and a second locking rod 273. The first locking rod 271 is rotatably mounted on the body of the mud storage trolley 23. The lock cylinder 272 is welded to the first locking rod 271, and the second locking rod 273 is fixed to the front door 231. Furthermore, the lock cylinder 272 has a latch, which can lock the second locking rod 273 when it is engaged in the latch. When the first locking rod 271 rotates, it can unlock the second locking rod 273 engaged in the latch.

[0075] When the front door 231 is closed, the second locking rod 273 first lifts the lock cylinder 272, causing the lock cylinder 272 and the first locking rod 271 to rotate synchronously. After the second locking rod 273 enters the latch of the lock cylinder 272, the lock cylinder 272, under its own weight, drives the first locking rod 271 to rotate synchronously, locking the second locking rod 273, thereby locking the front door 231. When the front door 231 is opened, lifting and rotating the first locking rod 271 causes the lock cylinder 272 to rotate synchronously, disengaging the latch of the lock cylinder 272 from the second locking rod 273, allowing the second locking rod 273 to move freely, thus unlocking the front door 231.

[0076] Furthermore, the sludge unloading mechanism 3 is also equipped with a linkage door opening assembly 33 and a pulley door closing assembly 34. The linkage door opening assembly 33 is tractively connected to the first locking rod 271 and can drive the first locking rod 271 to rotate, thereby unlocking the front door lock assembly 27. The pulley door closing assembly 34 is fixedly installed on the foundation surface 4 and corresponds to the front door 231 in the open state. During the tilting frame 31 tilting and descending, the pulley door closing assembly 34 can push the front door 231 upward relative to it, causing the front door 231 to close towards the front door of the sludge storage trolley 23, and finally locking the front door lock assembly 27.

[0077] The linkage door opening assembly 33 includes a linkage drive component and a transmission link. The linkage drive component can be a hydraulic cylinder, and the transmission link is a linear three-bar linkage. The middle section of the link is movably mounted on the tilting frame 31, and the two ends are movably connected to two link sections respectively. Under the drive of the linkage drive component, the link close to the first locking rod 271 can rotate the first locking rod 271, thereby unlocking the front door lock assembly 27. The pulley door closing assembly 34 includes a curved frame. The upper part of the curved frame is bent forward, and the lower part is vertical. Multiple pulleys are provided on the curved frame. The multiple pulleys are arranged from top to bottom along the curved structure of the curved frame. When the mud storage trolley 23 tilts and descends with the tilting frame 31, the front door 231 can slowly rotate backward and upward with the structural trend of the curved frame and under the rolling contact of the pulleys, thereby closing the front door 231.

[0078] Please see again. Figure 7 As shown, a top door 232 is provided on the sludge storage trolley 23. The top door 232 is provided on the sludge storage trolley 23 and can be opened and closed in a direction that is close to or away from the dewatering mechanism 1. When the sludge storage trolley 23 enters the dewatering mechanism 1 for sludge loading, the top door 232 can be opened to allow material to be discharged from the top for loading. After loading is completed, during the transfer to the sludge unloading mechanism 3 for sludge unloading, the top door 232 can be closed to achieve closed transfer and transportation.

[0079] Furthermore, a sealing strip 28 is provided on the front door 231 to form a seal with the body of the sludge storage trolley 23, and a sealing strip 28 is provided on the body of the sludge storage trolley 23 to form a seal with the top door 232. Thus, during the transfer and transportation of sludge, after the front door 231 and top door 232 are closed, the sludge storage trolley 23 can perform a closed-loop transfer and transportation with good sealing performance, preventing the odor emitted by the sludge from dispersing into the air and effectively ensuring the air quality of the working environment.

[0080] In a preferred embodiment, please refer to Figure 7 As shown, a handle 233 is provided at the top of the top door 232; and see also Figure 1 As shown, the dewatering frame 12 of the dewatering mechanism 1 has a top rod 13 protruding towards the sludge unloading mechanism 3 on the side near the sludge unloading mechanism 3, and the top rod 13 has a retaining sleeve 14. During the process of the sludge storage trolley 23 sliding into the dewatering mechanism 1 from right to left, the top rod 13 can extend into the handle 233 of the top door 232, and the retaining sleeve 14 engages with the handle 233 to open the top door 232.

[0081] Additionally, a top door positioning component 37 is provided on the side of the tilting frame 31 away from the first track 21, which can position the top door 232. When the sludge storage trolley 23 is transferred from left to right to the sludge unloading mechanism 3, the top door positioning component 37 can position and tighten the top door 232, and cause the top door 232 to close automatically.

[0082] Thus, the automatic opening and closing of the top door 232 is achieved through mechanical structure design. The design is ingenious and the structure is simple, enabling stable and efficient automated operation.

[0083] In another preferred embodiment, a positioning buffer 38 is provided on the side of the tilting frame 31 away from the first track 21. When the sludge storage trolley 23 is transferred onto the tilting frame 31, the positioning buffer 38 can position and buffer the sludge storage trolley 23, preventing it from rushing out of the second track 22. Furthermore, based on the positioning buffer 38, during the tilting process of the sludge storage trolley 23 with the tilting frame 31, the right side of the sludge storage trolley 23 can be limited and fixed, working together with the anti-return component 36 to prevent the sludge storage trolley 23 from sliding off the tilting frame 31 during the tilting and unloading process.

[0084] In a preferred embodiment, a weight detection sensor is provided on the tilting frame 31. When the mud storage trolley 23 is transferred to the second track 22, the weight detection sensor can automatically measure the weight of the mud storage trolley 23 to calculate its remaining capacity. When the weight detection sensor detects that the remaining capacity of the mud storage trolley 23 is insufficient, it can issue an alarm sound and display a text message on the operation screen.

[0085] In an optional embodiment, the dewatering mechanism 1, the conveying mechanism 2, and the sludge unloading mechanism 3 are controlled independently; or, the dewatering mechanism 1, the conveying mechanism 2, and the sludge unloading mechanism 3 can be connected by a PLC controller, and the PLC system can achieve linkage control.

[0086] Optionally, a position sensor is installed on the first track 21 to detect and sense the position of the mud storage trolley 23 as it moves onto the first track 21 (specifically at the position corresponding to the discharge port 121), thereby achieving precise mud loading. The position sensor can also feed back the detection system to the dewatering machine 11. The dewatering machine 11 starts working upon receiving the position signal; otherwise, it does not work.

[0087] Example 1

[0088] When using the sludge treatment loading system of the present invention for sludge treatment, the operation process includes standby state, sludge loading state and sludge unloading state, and the processing steps are as follows.

[0089] (1) When the system is in standby mode, the tilting frame 31 of the sludge unloading mechanism 3 is in the origin position and is parallel to the foundation surface 4. The output end of the conveying drive component 24 extends out and the sludge storage trolley 23 is located on the second track 22. The front door 231 and the top door 232 of the sludge storage trolley 23 are closed, and the sludge odor and sludge moisture in the sludge storage trolley 23 are completely sealed to ensure the air quality of the workshop working environment.

[0090] (2) The system enters the sludge loading state; the output end of the conveying drive component 24 retracts, and the sludge storage trolley 23 is pulled to the left. The top door 232 of the sludge storage trolley 23 is automatically opened during the leftward movement through the action of the top rod 13 and the clamp 14. After the sludge storage trolley 23 is moved to the position, the dewatering machine 11 of the dewatering mechanism 1 starts to work. The sludge produced by the dewatering machine 11 is discharged through the discharge port 121 and loaded onto the sludge storage trolley 23.

[0091] (3) After the mud is loaded, the output end of the conveying drive unit 24 extends and pushes the mud storage trolley 23 to the second track 22. The mud storage trolley 23 is stably stopped on the tilting frame 31 by the positioning buffer 38, and the top door 232 is completely closed by the top door positioning component 37.

[0092] (4) At this time, please refer to Figure 9a and Figure 9b As shown, the truck 5 enters the designated mud loading area on the foundation surface 4 and begins unloading mud, and the system enters the unloading state; the output end of the tilting hydraulic cylinder 32 extends, the tilting frame 31 drives the mud storage trolley 23 to tilt together, the slot 29 and the clip 35 are interlocked to ensure that the mud storage trolley 23 will not detach from the tilting frame 31, at the same time the movable clip 25 on the mud storage trolley 23 disengages from the movable joint 26 on the conveying drive component 24, and the gas spring 361 of the check component 36 extends and drives the check plate 362 to rotate to prevent the mud storage trolley 23 from turning back;

[0093] After the tilting frame 31 is tilted into place (e.g., the angle between the tilting frame 31 and the foundation surface 4 is 60°), the connecting rod door opening assembly 33 unlocks the front door lock assembly 27 of the mud storage trolley 23, so that the front door 231 is opened; the sludge in the mud storage trolley 23 is poured into the cargo box of the truck 5 under the action of gravity, completing the unloading and loading of sludge.

[0094] (5) After the mud unloading and loading are completed, the output end of the tilting hydraulic cylinder 32 retracts, causing the tilting frame 31 to tilt back to its initial state and fit against the foundation surface 4. At this time, the end of the check plate 362 of the check component 36 connected to the gas spring 361 rotates under the action of ground pressure, causing the gas spring 361 to automatically retract and close. Meanwhile, the front door 231 of the mud storage trolley 23 closes automatically through the pulley door closing component 34, and the movable clamp 25 on the mud storage trolley 23 re-engages with the movable joint 26 on the output end of the conveying drive component 24, and the system enters the standby state again.
