Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and particularly to a sludge loading rack for a sludge plant. Background Art

[0002] At present, in the end link of sludge treatment in a sewage treatment plant, after the sludge is collected, it needs to be bagged and transported to a designated area (such as a draining area). Currently, the manual cooperation mode is generally adopted: after the sludge dewatering equipment dehydrates the sludge, in the sludge buffer hopper, one operator manually opens the sludge bag and maintains the position of the bag mouth, and another operator shovels the sludge in the sludge buffer hopper into the bag. After being filled, it is manually carried or transferred by a simple trolley. In some sludge transfer trolleys in certain scenarios, the bracket is provided with an edge blocking structure, and the sludge bag is located in the center. However, during the bagging process, an additional person is still required to continuously straighten the bag body to prevent it from tipping over. Moreover, its structure is mostly rigidly welded and fixed, unable to adapt to different specifications of bag mouths, and lacking a height adjustment function.

[0003] In the prior art, such devices have significant defects: manual bag opening and shoveling require two people to cooperate, with high labor intensity and low efficiency; the simple bracket or trolley cannot automatically adjust the support height according to the sludge filling amount, and the bag mouth is prone to shift due to the filling impact, resulting in leakage. The height adjustment depends on manual step-by-step operation, and the filling process needs to be interrupted repeatedly to adjust the bag mouth height, seriously affecting the continuity of the operation; the size of the carrying platform is fixed, it is difficult to adapt to different specifications of bag mouths, and it is easy to cause unstable fixation due to too large a gap between the bag body and the platform; the overall structure lacks a folding or modular design, and the components need to be disassembled during storage, occupying a large space and having a low deployment efficiency; in addition, there is no dynamic feedback mechanism during the filling process, and the support height cannot be automatically adjusted according to the sludge filling amount. The operator needs to monitor the state of the bag body throughout the process to prevent deviation or leakage. The sludge bagging link has a high labor cost, low operation efficiency, and a risk of leakage and pollution, restricting the coherence and safety of the overall sludge treatment process.

Detailed Description of the Preferred Embodiment

[0029] Example 1: As shown in Figure 1-11 , a sludge loading rack for a sludge plant includes a carrier rack. A plurality of moving wheels 5 are provided at the lower end of the carrier rack. The carrier rack includes a plurality of foldable carrier plates 3. An upright frame 1 and a plurality of support rod assemblies are provided on the carrier rack. A plurality of cord belts 16 are provided between the upright frame 1 and each support rod assembly in the height direction. The upright frame 1, the support rod assemblies, and the cord belts 16 form a sludge bag placement position.

[0030] An armrest 4 is provided at the upper end of the upright frame 1 for convenient gripping.

[0031] One support rod assembly is provided on each side of the upright frame 1. The upright frame 1 and the two support rod assemblies are arranged in a V shape. After connecting the upper cord belt 16, the inner side of the V-shaped layout is the sludge bag placement position. The outer side of the sludge bag can lean against the upright frame 1, the two support rods, and the cord belt 16 to prevent tipping over.

[0032] In a preferred solution, the support rod assembly includes a sleeve rod 7. A lifting rod 8 is provided inside the sleeve rod 7. A support rod 12 is provided at the upper end of the lifting rod 8. The support rod 12 is used to support the mouth of the sludge bag.

[0033] After the sludge bag is manually opened, the bottom end is placed on the carrier rack, and the mouth of the bag can be turned up and rolled on the support rod 12 to be opened.

[0034] In a preferred solution, a support rod clamping sleeve 13 with an opening on one side is further provided. The support rod clamping sleeve 13 is buckled outside the support rod 12. A hinge member 14 is provided at the upper end of the lifting rod 8. One end of the support rod clamping sleeve 13 is hinged to the upper end of the lifting rod 8 through the hinge member 14.

[0035] After the mouth of the sludge bag is turned up and rolled on the support rod 12, the support rod clamping sleeve 13 can be turned to buckle outside the support rod 12 to clamp the mouth of the bag.

[0036] In a preferred solution, a notch groove is provided on one side of the lifting rod 8. The first end of the cord belt 16 passes through the sleeve rod 7 and is inserted into the sleeve rod 7. A connecting seat 17 is provided for the first end of the cord belt 16 in the notch groove. An abutting buckle 19 is provided on the side of the connecting seat 17 close to the lifting rod 8. A second spring 18 is provided on one side of the connecting seat 17 to abut against the inner wall of the sleeve rod 7. A first spring 9 is provided at the bottom end of the lifting rod 8 protruding out of the sleeve rod 7.

[0037] There is only one abutting hole 28.

[0038] Initially, the lifting rod 8 is in the lowest position and the mouth of the sludge bag is relatively low. When the staff shovels sludge into the sludge bag, the shovel does not need to be lifted very high, which can save physical strength. At this time, the abutting hole 28 is in the lowest position and the first spring 9 is in a compressed state. When the sludge in the sludge bag gradually increases, the sludge bag expands and squeezes the lower rope belt 16. This rope belt 16 pulls the lowermost connecting seat 17, causing the abutting buckle 19 to disengage from the abutting hole 28. Under the thrust of the first spring 9, the mouth of the sludge bag rises as the lifting rod 8 rises, and the abutting hole 28 rises accordingly until it is locked by the abutting buckle 19 at the upper layer height. When the sludge continues to be filled, the upper part of the sludge bag expands and squeezes the rope belt 16 at this height, and the abutting buckle 19 at this height is pulled out of the abutting hole 28, and the lifting rod 8 rises again. This cycle continues until the lifting rod 8 raises the mouth of the sludge bag to the apex.

[0039] In a preferred embodiment, a plurality of rotatable rotating shafts 15 are provided inside the vertical frame 1. The second ends of the respective rope belts 16 pass through the vertical frame 1 and are wound around the respective rotating shafts 15. Driven gears 22 are provided at the upper ends of the respective rotating shafts 15. A housing 20 is provided at the upper end of the vertical frame 1. A through hole is provided in the center of the housing 20. A rotatable rotating handle 24 is provided at the through hole. A third spring 23 is provided at the lower end of the rotating handle 24. The respective driven gears 22 are respectively engaged with the third spring 23.

[0040] Rotating the rotating handle 24 drives the respective rotating shafts 15 to rotate, and the rope belts 16 can be wound around the rotating shafts 15. A cavity is provided at this position of the vertical frame 1 to accommodate the wound rope belts 16.

[0041] In a preferred embodiment, a cap 27 is provided at the lower end of the rotating handle 24. A toothed portion 26 is provided at the orifice of the through hole on the inner side of the housing 20. A third spring 23 is also provided inside the housing 20. One end of the third spring 23 abuts against the cap 27 so that the cap 27 abuts against the toothed portion 26.

[0042] When the toothed portion 26 and the cap 27 are disengaged, the rotating handle 24 is stuck and cannot be rotated. It is necessary to manually press the rotating handle 24 while disengaging the cap 27 from the toothed portion 26 and rotate the rotating handle 24 to wind up the rope belt 16.

[0043] In a preferred embodiment, the carrier plate 3 is of a semi-circular structure. The carrier frame includes two carrier plates 3 that can be spliced into a complete circular structure. The two carrier plates 3 are hinged to each other, and the carrier plate 3 close to the vertical frame 1 is hinged to the lower end of the vertical frame 1.

[0044] A guide seat 34 is provided at the lower end of the vertical frame 1. A slidable guide rod 35 is provided inside the guide seat 34. A U-shaped clamp 31 is provided at the end of the guide rod 35. A counterbore 32 is provided at the end of the guide seat 34. A fourth spring 33 is provided inside the counterbore 32. The fourth spring 33 abuts against the end of the U-shaped clamp 31. When the carrier plate 3 is flattened, the U-shaped clamp 31 clamps the carrier plate 3 to prevent the carrier plate 3 from flipping. When the carrier plate 3 needs to be folded, first pull the U-shaped clamp 31 to withdraw it from the carrier plate 3.

[0045] In a preferred embodiment, a plurality of positioning holes 6 are provided on each carrier plate 3. The lower end of the sleeve rod 7 is sleeved with the positioning hole 6.

[0046] According to the size of the sludge bag, a suitable positioning hole 6 can be selected to install the sleeve rod 7, and the size of the placement position of the sludge bag can be adjusted arbitrarily.

[0047] When folding, the support rod assembly can be removed as a whole and snapped into the buckle rings 2 on both sides.

[0048] In a preferred embodiment, a movable joint 29 is provided at the lower end of the sleeve rod 7. The movable joint 29 is rotatably sleeved with the sleeve rod 7, and the lower end of the movable joint 29 is threadedly connected to the positioning hole 6.

[0049] When the movable joint 29 is screwed into the positioning hole 6, the outlet of the cord 16 on the sleeve rod 7 can always face the vertical frame 1, avoiding the cord 16 being wound around the sleeve rod 7 due to the rotation of the sleeve rod 7.

[0050] In a preferred embodiment, a plurality of annular grooves are provided on the outer wall of the lower end of the sleeve rod 7. A plurality of setscrew pins 30 connected by threads are provided on the side wall of the upper end of the movable joint 29. One end of the setscrew pin 30 is inserted into the annular groove. The setscrew pin 30 is only inserted into the annular groove and is not tightened, ensuring that the movable joint 29 can rotate relative to the sleeve rod 7 without moving around.

[0051] Embodiment 2: A sludge loading rack for a sludge plant, comprising: a vertical frame 1, a plurality of buckle rings 2, and two carrier plates 3; an installation cavity is formed inside the vertical frame 1, and two push handrails 4 are installed on the upper part. A plurality of buckle rings 2 are respectively installed on both sides of the vertical frame 1. Two carrier plates 3 are rotatably arranged on one side of the bottom end of the vertical frame 1 through hinge seats. The carrier plates 3 are arranged in a semicircular shape and are connected by hinges. A plurality of moving wheels 5 are provided at the bottom ends of the vertical frame 1 and the two carrier plates 3. A number of positioning holes 6 are provided on the two carrier plates 3.

[0052] Support component, the support component includes: two sleeve rods 7, two lifting rods 8 and a first spring 9; the bottom ends of the two sleeve rods 7 are installed with protrusions, and the sleeve rods 7 are inserted into the corresponding positioning holes 6 through the protrusions, thereby completing the positioning of the sleeve rods 7. By inserting into different positioning holes 6, bags of different sizes can be fixed, thereby completing the loading and transportation of sludge. The lifting rods 8 are arranged in the sleeve rods 7 so as to be movable in the vertical direction. The bottom end of the first spring 9 is fixedly installed at the bottom end inside the sleeve rod 7, and the top end is fixedly connected to the bottom end of the lifting rod 8.

[0053] A plurality of guide rails 10 are arranged inside the sleeve rod 7, and a plurality of docking chutes 11 matching the guide rails 10 are arranged on the lifting rod 8. The guide rails 10 and the docking chutes 11 are used to limit the lifting rod 8 during vertical movement and ensure the stable movement of the lifting rod 8.

[0054] Fixing component, the fixing component includes: a support rod 12 and a support rod collar 13. The two support rods 12 are respectively fixedly installed at the top ends of the two lifting rods 8. Hinged parts 14 are installed on the two support rod collars 13 and are rotatably arranged on the two support rods 12 through the hinged parts 14. Anti-slip patterns that match each other are provided on the surfaces of the support rod 12 and the support rod collar 13, and the two are buckled with each other by means of a buckle to fix the bag mouth of the sludge bag.

[0055] A rotating shaft 15 and a rope 16 are arranged inside the placement cavity. Among them, the two rotating shafts 15 are respectively rotatably arranged inside the placement cavity and are parallel to the vertical frame 1. The top end of the rotating shaft 15 extends to the top end of the vertical frame 1, and one ends of a plurality of ropes 16 are respectively wound around the two rotating shafts 15, and the other ends extend into the sleeve rod 7; A connecting seat 17 is fixedly arranged at one end of the rope 16. The connecting seat 17 is fixed inside the sleeve rod 7 through a plurality of second springs 18, and a contact buckle 19 is correspondingly installed at the other end of the connecting seat 17; The top end of the vertical vertical rod is installed with a housing 20. Inside the housing 20, there are a driving gear 21, a driven gear 22, a third spring 23 and a rotating handle 24. The two driven gears 22 are respectively fixedly installed at the top ends of the two rotating shafts 15. The driven gears 22 are rotatably arranged in the middle part inside the housing 20 and mesh with the two driven gears 22. A connecting block 25 is fixedly installed on the driving gear 21. The connecting block 25 is set to be polygonal. The third spring 23 is arranged on the driving gear 21. The rotating handle 24 is set to be in the shape of a capital I and is fixedly connected to the third spring 23. The rotating handle 24 is inserted into the connecting block 25. A plurality of teeth 26 are arranged inside the housing 20. The plurality of teeth 26 mesh with the rotating handle 24. A rotatable gear disk 27 is also installed on the rotating handle 24; When it is necessary to bag the sludge, the staff first turn the carrier plate 3 so that it is perpendicular to the vertical frame 1. Then, remove the sleeve rod 7 on the loop and insert the sleeve rod 7 through the bottom protrusion into the corresponding positioning hole 6 according to the opening size of the bag. During the movement of the sleeve rod 7, press down the rotating handle 24. At this time, the rotating handle 24 disengages from the tooth 26, and at the same time, pull the sleeve rod 7. The rope belt 16 will extend as the rotating shaft 15 rotates. Finally, the sleeve rod 7 is inserted into the appropriate positioning hole 6. Then, turn the rod holder sleeve 13 on the support rod 12 and place the opening part of the bag outside the outer wall of the support rod 12. Finally, turn the rod holder sleeve 13 to engage with the fixing part, which realizes the support and fixation of the bag opening. The anti-slip pattern is used to increase the friction between the support rod 12 and the rod holder sleeve 13, making the fixation of the bag opening more firm; press the rotating handle 24 to release the tooth disc 27, and by pulling the sleeve rod 7, the rotating handle 24 can be rotated smoothly.

[0056] During the use process, when the sludge does not fill the height of the rope belt 16 at the lowest end, the rope belt 16 at this position is not stressed, and the abutting buckle 19 is stably inserted into the abutting hole 28 of the lifting rod 8 to realize the positioning of the lifting rod 8. When the sludge fills to the height of this rope belt 16, by filling the sludge into the bag, the bag expands, and then the rope belt 16 is stressed and moves. The connecting seat 17 drives the second spring 18 to contract, causing the abutting buckle 19 to disengage from the abutting hole 28. At this time, the first spring 9 extends and pushes the lifting rod 8 upward, so that the lifting rod 8 rises a certain distance. During the rising process of the lifting rod 8, the rope belt 16 and the abutting buckle 19 above the bottom rope belt 16 are squeezed, and the second spring 18 contracts. When the abutting hole 28 on the lifting rod 8 corresponds to the abutting buckle 19 on the connecting seat 17, the abutting buckle 19 is inserted into the abutting hole 28. When the sludge fills to the position of this rope belt 16, due to the expansion of the bag, the rope belt 16 is stressed and pulls the connecting seat 17 to move outward from the sleeve rod 7. At this time, the abutting hole 28 and the abutting buckle 19 disengage, and the lifting rod 8 continues to rise, causing the abutting hole 28 to be correspondingly stuck with the upper abutting buckle 19. When bagging the sludge, there is no need for manual operation, and the bag automatically rises upward with the filling height. After filling, move the bag full of sludge through the moving wheel 5 at the bottom end of the carrier plate 3. After moving to the designated position, turn the rod holder sleeve 13 to disengage from the support rod 12, so that the bag opening is completely exposed. Finally, remove the bag full of sludge.

[0057] The linkage effect of the rope belt and the second spring can, on the one hand, realize the automatic lifting and lowering of the lifting rod according to the filling height, and on the other hand, support and limit the bag.

[0058] After the use of the device is completed, the protrusion at the bottom end of the sleeve rod 7 is disengaged from the positioning hole 6, and the sleeve rod 7 is stored in the ring buckle, and the two supporting plates 3 are folded by the hinge, so that the supporting plate 3 and the stand 1 are finally in a state of being parallel to each other, and the rotating handle 24 is pressed and rotated, and the rotation of the rotating shaft 15 is achieved through the linkage of the driving gear 21 and the driven gear 22, so that the rope 16 is wound. The device is small in size and easy to store and carry. At the same time, it can adapt to bags of different sizes to meet the filling requirements of different materials. At the same time, it can be automatically lifted upward according to the height of the filling material, without the need for manual operation by the staff, saving time and effort and reducing work intensity.

[0059] There are some problems with traditional auxiliary tooling: High dependence on manual labor: Height adjustment requires frequent manual operation, resulting in interruptions in the filling process and low efficiency; Insufficient adaptability: The size of the supporting platform is fixed and cannot adapt to bags of different specifications. The bag may slip or become unstable due to excessive gaps. Poor portability: The non-foldable rigid structure requires the disassembly of components for storage, which takes up a lot of space and is time-consuming to repeatedly deploy; Lack of dynamic feedback: There is a lack of automatic response mechanism to the expansion state of the bag during the filling process, and manual real-time monitoring of height changes is required, which can easily lead to leakage risks due to support lag.

[0060] This device has the following advantages: Adaptive height adjustment is achieved through the linkage of rope, abutment buckle and the second spring. When the sludge is filled to the set height, the bag expands, triggering the rope to be stressed, causing the abutment buckle to detach from the abutment hole of the lifting rod. The first spring pushes the lifting rod to automatically rise, realizing dynamic adjustment of the bag opening with the filling height.

[0061] Multi-level trigger control, multiple ropes and belts are set in layers, and lifting and lowering are triggered step by step to ensure the height adaptation at different filling stages. No manual intervention is required throughout the process, which significantly reduces the operation intensity.

[0062] Adjustable support assembly, the sleeve rod is flexibly matched with the positioning hole on the support plate through the bottom protrusion, and can be inserted into different hole positions to adapt to various bag opening sizes. The buckle structure of the support rod and the support rod sleeve can achieve quick fixing and loosening.

[0063] The anti-slip patterns on the surface of the support rod and the support rod sleeve enhance the friction, and the hinged hinges are combined to achieve double locking of the bag opening to ensure the stability of bags made of different materials.

[0064] The foldable support plate, the double semicircular support plate connected by hinges can be folded to be parallel to the stand, and the sleeve rod can be stored in the buckle, which greatly compresses the size of the device.

[0065] The rotating shaft is linked with the gear set. Press the rotating handle to drive the driving gear to drive the driven gear to rotate, wind up the rope belt, and improve the storage efficiency.

[0066] The I-shaped rotating handle and the cap, the rotating handle, the third spring and the engaging structure of the teeth can be freely rotated after pressing to adjust the length of the rope belt.

[0067] The moving wheels are integrally arranged. Moving wheels are provided at the bottom of the vertical frame and the carrier plate. After being filled, it can be directly pushed and transported, realizing the integration of loading and transportation.

[0068] Through mechanical linkage and modular design, it has the characteristics of adaptive adjustment, multi-size compatibility, and rapid storage. It uses the physical feedback of springs, rope belts, and gear sets to replace manual monitoring, solving the pain points such as the need for two people to cooperate in the sludge loading process, difficult height adjustment, unstable bag mouth fixation, and large equipment footprint, achieving a double breakthrough in efficiency and portability.

The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
