Technical Field

[0001] This utility model relates to the field of sludge dewatering technology, and more specifically to a sludge dewatering device. Background Technology

[0002] Sludge is a product of wastewater treatment. It is an extremely complex heterogeneous body composed of organic fragments, bacterial cells, inorganic particles, colloids, etc. In order to facilitate subsequent sludge treatment, sludge dewatering is required.

[0003] Currently, most sludge dewatering operations rely on hydraulic pressure to squeeze the sludge, forcing the water in the sludge through a filter screen to complete the dewatering process. However, using hydraulic pressure alone results in low dewatering efficiency and makes it difficult to meet the need for rapid dewatering.

[0004] In view of this, the present invention proposes a rapid dewatering sludge dewatering device to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sludge dewatering device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a sludge dewatering device, including a base, an installation frame welded to the upper surface of the base, a dewatering cylinder provided on the inner side of the installation frame, a collection cylinder rotatably connected to the bottom surface of the dewatering cylinder, a water collection cavity reserved between the dewatering cylinder and the collection cylinder, and a dewatering hole opened on the surface of the dewatering cylinder corresponding to the water collection cavity, a drain pipe embedded at the bottom of the collection cylinder, a squeezing component provided on the top of the installation frame corresponding to the dewatering cylinder, and a water-throwing component provided between the installation frame and the dewatering cylinder;

[0007] The extrusion assembly includes a first hydraulic rod embedded in the top of the mounting frame, and a lower pressure plate is fixedly installed at the telescopic end of the first hydraulic rod. The lower pressure plate is adapted to the upper opening of the dewatering cylinder.

[0008] The water-spinning assembly includes two shafts symmetrically arranged on both sides of the mounting frame. An mounting ring is fixedly installed at the close end of the two shafts. The dewatering cylinder is rotatably connected to the inner wall of the mounting ring, and a reduction motor is fixedly installed on the surface of the mounting ring. A gear disk is fixedly installed on the output shaft surface of the reduction motor, and a gear ring is fixedly installed on the outer wall of the dewatering cylinder. The gear disk and the gear ring mesh with each other.

[0010] As a further description of the above technical solution: an elastic sealing ring is fixedly installed on the side of the bottom end of the lower pressure plate, and the elastic sealing ring is adapted to the upper opening of the dehydration cylinder; by setting the elastic sealing ring, the tightness between the lower pressure plate and the dehydration cylinder can be improved, and the pressing effect can be improved.

[0011] As a further description of the above technical solution: the shaft and the mounting frame are rotatably connected, and the surface of the mounting frame is provided with a tilting discharge component corresponding to the shaft and the dewatering cylinder.

[0012] As a further description of the above technical solution: the tilting discharge assembly includes a tilting box fixedly installed on the right side of the mounting frame, a shaft rotatably connected to the tilting box, a second hydraulic rod embedded in the top of the tilting box, a straight rack fixedly installed at the telescopic end of the second hydraulic rod, and a gear plate fixedly installed on the surface of the shaft, with the straight rack and gear plate meshing with each other; by setting the tilting discharge assembly, after dewatering, the second hydraulic rod telescopically drives the straight rack to move, and based on the meshing of the straight rack and gear plate, the shaft can be deflected, so that the opening of the dewatering cylinder faces downward, thereby enabling the sludge after dewatering to be discharged quickly, achieving the purpose of improving the sludge dewatering processing efficiency.

[0013] As a further description of the above technical solution: a stirring rod is inserted into the surface of the lower pressure plate, and a tension spring is sleeved on the top of the stirring rod. The top of the tension spring is fixed to the top of the stirring rod, and the bottom of the stirring rod is fixed to the upper surface of the lower pressure plate. During dewatering, the stirring rod is used to agitate the sludge, which can promote the seepage of sewage from the inside of the sludge, thereby further improving the efficiency of sludge dewatering. Since the stirring rod is inserted into the surface of the lower pressure plate, the tension spring is used to flexibly limit the stirring rod, which can prevent rigid collision between the bottom of the stirring rod and the dewatering cylinder during the pressing of the lower pressure plate, thereby achieving the purpose of protecting the device.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. Compared with the prior art, this sludge dewatering device adds water-containing sludge into the dewatering cylinder. The first hydraulic rod extends and drives the lower pressure plate to squeeze the sludge. Wastewater passes through the dewatering hole into the water collection chamber and is then discharged to the outside through the drain pipe, thus achieving the purpose of sludge dewatering. At the same time, the gear disk is driven to rotate by the reduction motor. Based on the meshing of the gear disk and the gear ring, the dewatering cylinder can be driven to rotate inside the mounting ring, thereby driving the sludge to rotate. Under the action of centrifugal force, the wastewater can be promoted to flow out from the dewatering hole, thereby improving the dewatering efficiency.

[0018] 2. Compared with existing technologies, this sludge dewatering device improves the stability of the lower pressure plate's lifting and lowering by setting a first limiting slide bar, and achieves anti-torsion protection for the telescopic end of the first hydraulic rod; by setting an elastic sealing ring, it improves the tightness between the lower pressure plate and the dewatering cylinder, enhancing the pressing effect; by setting a tilting discharge component, after dewatering, the second hydraulic rod telescopically drives the rack to move, and based on the meshing of the rack and the gear plate, it can drive the shaft to deflect, causing the upper opening of the dewatering cylinder to face downwards, thereby enabling the rapid discharge of the dewatered sludge and improving the efficiency of sludge dewatering.

[0019] 3. Compared with existing technologies, this sludge dewatering device, by setting up a stirring rod, inserts the stirring rod into the sludge when the sludge is squeezed by the lower pressure plate. The dewatering cylinder is in a rotating state, and the stirring rod and the sludge are in a state of relative motion. The stirring rod agitates the sludge, which can promote the seepage of sewage from the inside of the sludge, thereby further improving the efficiency of sludge dewatering. On the other hand, since the stirring rod is inserted into the surface of the lower pressure plate, the stirring rod is flexibly limited by a tension spring, which can avoid rigid collision between the bottom of the stirring rod and the dewatering cylinder during the pressing of the lower pressure plate, thereby achieving the purpose of protecting the device.

[0020] 4. Compared with the prior art, this sludge dewatering device can improve the stability of the dewatering cylinder by controlling the extension of the third hydraulic rod to drive the positioning seat to clamp with the edge of the collection cylinder when preparing to carry out the dewatering action; by setting the second limit slide bar, the stability of the positioning seat movement can be improved, and the torsion protection effect of the extension end of the third hydraulic rod can be achieved.

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The sludge dewatering device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Reference Figures 1 to 4 This utility model provides a sludge dewatering device, including a base 1, a mounting frame 2 welded to the upper surface of the base 1, a control panel fixedly mounted on the surface of the mounting frame 2, and the control panel being electrically connected to an external power source through wires.

[0028] The inner side of the mounting frame 2 is provided with a dehydration cylinder 3. A collection cylinder 4 is rotatably connected to the bottom surface of the dehydration cylinder 3. A water collection cavity is reserved between the dehydration cylinder 3 and the collection cylinder 4. A dehydration hole 5 is opened on the surface of the dehydration cylinder 3 corresponding to the water collection cavity. A drain pipe 6 is embedded at the bottom of the collection cylinder 4. A squeezing component is provided on the top of the mounting frame 2 corresponding to the dehydration cylinder 3. A water-spraying component is provided between the mounting frame 2 and the dehydration cylinder 3.

[0029] The extrusion assembly includes a first hydraulic rod 7 embedded in the top of the mounting frame 2, and a lower pressure plate 8 is fixedly installed at the telescopic end of the first hydraulic rod 7. The lower pressure plate 8 is adapted to the upper opening of the dewatering cylinder 3.

[0030] It is worth noting that when using this sludge dewatering device, water-containing sludge is added into the dewatering cylinder 3. The first hydraulic rod 7 is extended by controlling the control panel. The extension of the first hydraulic rod 7 drives the lower pressure plate 8 to squeeze the sludge. The sewage passes through the dewatering hole 5 and enters the water collection chamber, and then is discharged to the outside through the drain pipe 6, thus achieving the purpose of sludge dewatering treatment.

[0031] A first limiting slide rod 14 is fixedly installed on the upper surface of the lower pressure plate 8, and the first limiting slide rod 14 is slidably connected to the surface of the mounting bracket 2.

[0032] By setting the first limit slide bar 14, the stability of the lower pressure plate 8 in lifting and lowering can be improved, and the purpose of anti-torsion protection can be achieved for the telescopic end of the first hydraulic rod 7.

[0033] An elastic sealing ring 15 is fixedly installed on the side of the bottom end of the lower pressure plate 8, and the elastic sealing ring 15 is adapted to the upper opening of the dewatering cylinder 3.

[0034] By setting the elastic sealing ring 15, the tightness between the lower pressure plate 8 and the dewatering cylinder 3 can be improved, thus enhancing the pressing effect.

[0035] The water-spinning assembly includes two shafts 9 symmetrically arranged on both sides of the mounting frame 2. A mounting ring 10 is fixedly installed at the close end of the two shafts 9. The dewatering cylinder 3 is rotatably connected to the inner wall of the mounting ring 10. A reduction motor 11 is fixedly installed on the surface of the mounting ring 10. A gear disk 12 is fixedly installed on the output shaft surface of the reduction motor 11. A gear ring 13 is fixedly installed on the outer wall of the dewatering cylinder 3. The gear disk 12 and the gear ring 13 mesh with each other.

[0036] It is worth noting that while the sludge is squeezed and dewatered by the lower pressure plate 8, the gear disk 12 is driven to rotate by starting the reduction motor 11. Based on the meshing of the gear disk 12 and the gear ring 13, the dewatering cylinder 3 can be driven to rotate inside the mounting ring 10, thereby driving the sludge to rotate. Under the action of centrifugal force, the sewage can be promoted to flow out from the dewatering hole 5, thereby achieving the purpose of improving the dewatering efficiency.

[0037] A stirring rod 20 is inserted into the surface of the lower pressure plate 8, and a tension spring 21 is sleeved on the top end of the stirring rod 20. The top end of the tension spring 21 is fixed to the top end of the stirring rod 20, and the bottom end of the stirring rod 20 is fixed to the upper surface of the lower pressure plate 8.

[0038] It is worth noting that, by setting up a stirring rod 20, when the sludge is squeezed by the lower pressure plate 8, the stirring rod 20 is inserted into the sludge, the dewatering cylinder 3 is in a rotating state, and the stirring rod 20 and the sludge are in a state of relative motion. By using the stirring rod 20 to stir the sludge, the sewage inside the sludge can be promoted to seep out, thereby further improving the efficiency of sludge dewatering.

[0039] On the other hand, since the stirring rod 20 is inserted into the surface of the lower pressure plate 8, the tension spring 21 is used to flexibly limit the stirring rod 20, which can prevent the bottom of the stirring rod 20 from rigidly colliding with the dewatering cylinder 3 during the pressing of the lower pressure plate 8, thereby achieving the purpose of protecting the device.

[0040] The side wall of the mounting bracket 2 is symmetrically fitted with a third hydraulic rod 22. The telescopic end of the third hydraulic rod 22 is fixedly installed with a positioning bracket 23. When the third hydraulic rod 22 extends, the positioning bracket 23 engages with the edge of the collecting cylinder 4.

[0041] It is worth noting that when preparing for the dehydration process, the stability of the dehydration cylinder 3 can be improved by controlling the extension of the third hydraulic rod 22 to clamp the positioning seat 23 to the edge of the collection cylinder 4.

[0042] A second limiting slide bar 24 is fixedly installed on the surface of the positioning bracket 23, and the second limiting slide bar 24 is slidably connected to the surface of the mounting bracket 2.

[0043] Furthermore, by setting a second limiting slide bar 24, the stability of the positioning bracket 23 movement can be improved, and the effect of anti-torsion protection can be achieved for the telescopic end of the third hydraulic rod 22.

[0044] The shaft 9 and the mounting frame 2 are rotatably connected, and the surface of the mounting frame 2 is provided with a tilting discharge component corresponding to the shaft 9 and the dewatering cylinder 3.

[0045] The tilting discharge assembly includes a tilting box 16 fixedly installed on the right side of the mounting frame 2, a shaft 9 rotatably connected to the tilting box 16, a second hydraulic rod 17 embedded in the top of the tilting box 16, a straight rack 18 fixedly installed at the telescopic end of the second hydraulic rod 17, and a gear plate 19 fixedly installed on the surface of the shaft 9, with the straight rack 18 and the gear plate 19 meshing with each other.

[0046] It is worth noting that by setting up a tilting discharge component, after dewatering, the second hydraulic rod 17 extends and retracts to drive the rack 18 to move. Based on the meshing of the rack 18 and the gear plate 19, the shaft 9 can be driven to deflect, so that the upper opening of the dewatering cylinder 3 faces downward, thereby enabling the sludge after dewatering to be quickly discharged from the dewatering cylinder 3, thus achieving the purpose of improving the efficiency of sludge dewatering processing.

[0047] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
