Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, and more specifically to a sludge dewatering machine. Background Technology

[0002] A sludge dewatering machine is a continuously operating sludge treatment device. Sludge dewatering machines are classified into: belt sludge dewatering machines, plate and frame sludge dewatering machines, stack sludge dewatering machines, and centrifugal sludge dewatering machines. Sludge dewatering machines are characterized by low sludge moisture content, stable operation, low energy consumption, relatively simple control and management, and convenient maintenance. Sludge treatment can be divided into two processes: sludge dewatering and sludge drying. Therefore, to meet the adaptability requirements of various types of sludge for dewatering machines, commonly used models of sludge dewatering machines include: centrifugal, belt filter, spiral ring, and plate and frame.

[0003] Chinese patent document CN221319749U discloses a screw press sludge dewatering machine, including a base and a stirring mechanism; the base has a stirring box on its upper right side, a buffer box on the right end of the stirring box, and the right end of the stirring box and the left end of the buffer box are connected by a connecting port. An installation plate is installed on the upper side inside the buffer box. A protective frame is installed on the upper left side of the base. Fixing plates are installed between the front and rear walls of the protective frame. An installation pipe is installed inside the protective frame. The fixing plates are fixedly connected to the installation pipe through an installation groove on the right end. A screw rod is rotatably connected inside the installation pipe via a bearing. A sludge discharge port is provided on the left side of the outer arc surface of the installation pipe. A water inlet on the upper side of the outer arc surface of the installation pipe is connected to an overflow port on the left end of the stirring box via a connecting pipe. Water outlets are provided on the lower side of the outer arc surface of the installation pipe. The stirring mechanism is located at the lower end of the installation plate; [Further details omitted] The system includes a control switch assembly located at the front end of the mixing tank. The input of the control switch assembly is electrically connected to an external power source, enabling control of the internal electrical components. The mixing mechanism includes a vertical rod, an adjusting plate, an output rod, and mixing blades. The vertical rod is rotatably connected to the center of the top wall of the mounting plate via bearings. An adjusting plate is located on the lower side of the outer arc surface of the vertical rod. The lower end of the adjusting plate is rotatably connected to an output rod via bearings. Evenly distributed mixing blades are located on the lower side of the outer arc surface of the output rod. The system also includes a motor located at the center of the upper part of the mounting plate. The lower end of the motor's output shaft is fixedly connected to the upper end of the vertical rod, and the input of the motor is electrically connected to the output of the control switch assembly. Finally, the system includes a geared motor located at the left end of the mounting tube. The right end of the geared motor's output shaft is fixedly connected to the left end of the screw rod, and the input of the geared motor is electrically connected to the output of the control switch assembly.

[0004] Before use, the screw press sludge dewatering machine is moved to the designated working location using external traction equipment. Then, the base is installed and connected to the corresponding workstation to support and fix the base and the equipment above. During operation, sludge and flocculant are poured into the buffer tank together. Then, the sludge and flocculant enter the mixing tank through the connection port. Afterward, the motor starts running via the control switch group. The motor's output shaft drives the upright to rotate, and the upright, through the adjusting plate, drives the output rod to rotate. This, in turn, drives the mixing blades to rotate, mixing the sludge and flocculant. During the rotation of the output rod, the drive gear revolves around the central gear, thus... The output rod rotates while also driving the mixing fan blades to rotate, further increasing the contact area between the sludge and flocculant. The mixed sludge enters the installation pipe through the connecting pipe. At this time, the geared motor starts running through the control switch group. The output shaft of the geared motor drives the screw rod to rotate, and the screw rod drives the sludge to move to the left. During the movement, the sludge is squeezed by the screw, thus separating the sludge and water. The separated water flows out through the drain outlet and finally collects inside the collection box. Then, the drain valve is opened, and the separated water is discharged through the drain pipe. The sludge is finally discharged through the sludge discharge outlet, thus achieving the dewatering of the sludge.

[0005] In the above technology, during the sludge dewatering process, when the sludge is conveyed in the installation pipe by a screw rod, the sludge conveyed to the area near the discharge port is relatively dry after dewatering, which makes it easy for the sludge to clump together in the installation pipe, causing blockage and resulting in low subsequent sludge treatment efficiency. Summary of the Invention

[0006] This invention provides a sludge dewatering machine, which aims to solve the technical problem in the prior art where, during the sludge dewatering process, when sludge is transported through a screw rod in the installation pipe, the sludge transported to the area near the discharge port is relatively dry after dewatering, making it easy for the sludge to clump together in the installation pipe and causing blockage, resulting in low subsequent sludge treatment efficiency.

[0007] This invention discloses a sludge dewatering machine, comprising a frame, a conveying pipe mounted on the frame, and a conveying auger disposed within the conveying pipe. A feed hopper and a discharge hopper are respectively disposed at both ends of the conveying pipe along the length of the frame. A mudguard is disposed at the discharge hopper of the conveying auger, and the mudguard rotates synchronously with the conveying auger. A discharge channel for sludge discharge is provided between the mudguard and the frame. A crushing device is disposed on the mudguard, comprising a crushing rod for crushing lumpy sludge and an adjusting component for driving the crushing rod. One end of the crushing rod is rotatably engaged with the mudguard. When the conveying auger drives the mudguard to rotate, it drives the crushing rod to rotate. During the rotation of the crushing rod, the adjusting component drives the crushing rod to rotate, thereby crushing the lumpy sludge passing through the discharge channel.

[0008] Beneficial effects: With the crushing device, sludge enters the conveying pipe from the feed hopper and is conveyed by the conveying auger. Wastewater during the dewatering process is discharged through the drain hole at the bottom of the conveying pipe. The sludge is continued to be conveyed by the conveying auger and, after dewatering, reaches the discharge channel between the mud baffle and the frame, where it falls out. When there is lumpy sludge, the crushing rod is driven by the adjusting component to strike and crush the lumpy sludge into smaller pieces. These smaller pieces are then discharged and eventually enter the discharge hopper. The crushing rod is continuously driven by the adjusting component to achieve continuous crushing of the sludge, preventing sludge blockage at the discharge channel and thus improving the efficiency of subsequent sludge treatment.

[0009] Preferably, the adjustment assembly includes a mounting bracket disposed on the mudguard, a torsion spring disposed within the mounting bracket, and a protrusion disposed on the frame for driving one end of the crushing rod away from the mudguard to crush the blocky sludge. One end of the torsion spring is connected to the mounting bracket, and the other end is connected to the crushing rod, and is used to drive the crushing rod to reset.

[0010] Beneficial effects: By setting up the protrusion and torsion spring, when the crushing rod rotates to the protrusion, the protrusion can squeeze the crushing rod, causing the crushing rod to rotate and compressing the torsion spring. When the crushing rod passes the protrusion, the torsion spring can release the elastic restoring force, thereby driving the crushing rod to reset and rotate. During the rotation of the crushing rod, the blocky sludge at the discharge channel is crushed, achieving efficient crushing of blocky sludge.

[0011] Preferably, the protrusion is provided with an arc-shaped surface, which is inclined away from the feed hopper along the rotation direction of the mudguard.

[0012] Beneficial effect: By setting the arc surface, when the crushing rod rotates to the protrusion, the crushing rod can rotate along the arc surface, making the rotation of the crushing rod more efficient.

[0013] Preferably, the side of the crushing rod closest to the protrusion is rotatably fitted with a rotating wheel adapted to the arc-shaped surface.

[0014] Beneficial effects: By setting up the rotating wheel, the rotating rod can drive the rotating wheel to rotate when it rotates. The rotating wheel rotates along the protrusion, making the movement of the rotating rod at the protrusion more efficient.

[0015] Preferably, the mudguard is slidably fitted to the conveying auger along the central axis of the conveying pipe, and the crushing rod is provided with a flushing device. The flushing device includes a high-pressure nozzle for flushing the sludge on the conveying auger near the discharge hopper, a water supply mechanism for supplying water to the high-pressure nozzle, and a rotating assembly for driving the high-pressure nozzle to rotate. The high-pressure nozzle is mounted on the crushing rod.

[0016] Beneficial effects: By setting up the flushing device, when it is necessary to clean the sludge near the discharge hopper of the conveying auger, the rotating component drives the high-pressure nozzle to rotate, so that the high-pressure nozzle is set towards the conveying auger. Then, water is supplied to the high-pressure nozzle through the water supply mechanism, and the flushing water is sprayed out through the high-pressure nozzle to clean the sludge near the discharge hopper of the conveying auger. This can prevent the sludge from clogging the conveying auger near the discharge hopper and further improve the efficiency of subsequent sludge treatment.

[0017] Preferably, the water supply mechanism includes a water supply pipe for supplying water to the high-pressure nozzle and a water supply assembly for supplying water to the water supply pipe, one end of the water supply pipe being connected to the high-pressure nozzle.

[0018] Beneficial effects: Water is supplied to the water supply pipe through the water supply component, and the water supply pipe delivers the flushing water to the high-pressure nozzle, which sprays it out for use, thereby cleaning the sludge near the discharge hopper of the conveying auger.

[0019] Preferably, the water supply assembly includes a water storage cavity disposed within the mudguard and a water supply component for supplying water to the water storage cavity, and one end of the water supply pipe is connected to the water storage cavity.

[0020] Beneficial effects: Activating the water supply unit can deliver flushing water to the water storage chamber, and then through the water storage chamber to the water supply pipe, thus supplying water to the high-pressure nozzles.

[0021] Preferably, the rotating assembly includes a fixed rack mounted on the frame and a rotating gear disposed on the crushing rod, the rotating gear meshing with the fixed rack.

[0022] Beneficial effects: By setting up a fixed rack and a rotating gear, when the crushing rod drives the rotating gear to move, the rotating gear can rotate due to the meshing of the rotating gear and the fixed rack, which in turn drives the crushing rod to rotate, thus realizing the rotation adjustment of the crushing rod.

[0023] Preferably, the frame is provided with a moving device, which includes a sliding sleeve for driving the mudguard to slide and a sliding assembly for driving the sliding sleeve to slide, wherein the sliding sleeve is rotatably engaged with the mudguard.

[0024] Beneficial effects: By setting up the moving device, when the sliding component is working, it can drive the sliding sleeve to move, and then drive the mudguard to move, so as to adjust the position of the mudguard and facilitate the washing of the part of the conveying auger near the discharge hopper.

[0025] Preferably, the sliding assembly includes a sliding frame connected to the sliding sleeve and a driver for driving the sliding frame to slide, the driver being mounted on the frame.

[0026] Beneficial effects: Starting the drive unit can drive the sliding frame to slide, which in turn drives the sliding sleeve to slide. The sliding sleeve drives the mudguard to slide, thereby adjusting the position of the mudguard and making operation more convenient.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. In this invention, by setting up a crushing device, the sewage in the sewage dewatering process is discharged through the drain hole at the bottom of the conveying pipe. The sludge is continued to be conveyed by the conveying auger and, after dewatering, reaches the discharge channel between the mud baffle and the frame. The sludge falls from the discharge channel. When there is lumpy sludge, the crushing rod is driven to move by the adjusting component. The crushing rod can strike the lumpy sludge, thereby breaking the lumpy sludge into smaller sludge. Then the smaller sludge can be discharged, avoiding the phenomenon of sludge clogging at the discharge channel, thereby improving the subsequent sludge treatment efficiency.

[0029] 2. In this invention, by setting up the protrusion and the torsion spring, when the crushing rod rotates to the protrusion, the protrusion can squeeze the crushing rod, causing the crushing rod to rotate and compressing the torsion spring. When the crushing rod passes the protrusion, the torsion spring can release the elastic restoring force, thereby driving the crushing rod to reset and rotate. During the rotation of the crushing rod, the blocky sludge at the discharge channel is crushed, achieving efficient crushing of blocky sludge.

[0030] 3. In this invention, by setting the arc-shaped surface, when the crushing rod rotates to the protrusion, the crushing rod can rotate along the arc-shaped surface, making the rotation of the crushing rod more efficient.

[0031] 4. In this invention, by setting up a flushing device, the high-pressure nozzle is rotated by a rotating component, so that the high-pressure nozzle is positioned towards the conveying auger. Then, water is supplied to the high-pressure nozzle by a water supply mechanism. The flushing water is sprayed out through the high-pressure nozzle to clean the sludge near the discharge hopper of the conveying auger. This can prevent the sludge from clogging the conveying auger near the discharge hopper and further improve the efficiency of subsequent sludge treatment.

[0032] 5. In this invention, by setting up a moving device, when the sliding component is working, it can drive the sliding sleeve to move, thereby driving the mudguard to move, realizing the adjustment of the position of the mudguard, which facilitates the washing of the position of the conveying auger near the discharge hopper.

[0043] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0044] Reference Figures 1-8 The present invention discloses a sludge dewatering machine, comprising a frame 1, a conveying pipe 2 disposed on the frame 1, and a conveying auger 3 disposed within the conveying pipe 2. A feed hopper 11 and a discharge hopper 12 are respectively disposed at both ends of the conveying pipe 2 along the length of the frame 1. The conveying pipe 2 is disposed along the length of the frame 1, and two conveying pipes are spaced apart along the width of the frame 1. A drain hole for wastewater discharge is provided at the bottom of the conveying pipe 2. The conveying auger 3 is rotatably fitted within the conveying pipe 2, and the end of the conveying shaft of the conveying auger 3 near the discharge hopper 12 is configured as a conical structure. A mounting box 9 is fixedly disposed on the frame 1 near the discharge hopper 12. The mounting box 9 is a hollow structure, and a hole for sludge discharge is provided at the bottom of the mounting box 9. A housing 10 is fixedly disposed on the frame 1 at the mounting box 9, and the housing 10 is located within the mounting box 9. A hole for sludge discharge is provided at the bottom of the housing 10. A drive assembly 8 is mounted on the mounting box 9, and the drive assembly 8 is used to drive the conveying auger 3 to rotate. When sludge needs to be dewatered, the sludge is first added to the feed hopper 11. The sludge enters the end of the conveying pipe 2 near the feed hopper 11 from the feed hopper 11. At the same time, the drive assembly 8 is started, which drives the conveying auger 3 to rotate. The conveying auger 3 conveys the sludge. During the process of conveying the sludge to the discharge hopper 12 in the conveying pipe 2, it is gradually squeezed by the conveying shaft of the conveying auger 3. The water in the sludge is gradually squeezed out and discharged from the drain hole at the bottom of the conveying pipe 2. Finally, it enters the frame 1 for further processing. The sludge continues to be conveyed with the conveying auger 3 and enters the housing 10. It is discharged through the hole at the bottom of the housing 10 and finally enters the discharge hopper 12 for further processing, thus completing the sludge dewatering operation.

[0045] Among them, reference Figure 1 , Figure 2 and Figure 3The drive assembly 8 directly uses an electric motor to drive the conveying shaft of the conveying auger 3 through a reduction gearbox. A mudguard 4 is installed at the discharge hopper 12 of the conveying auger 3. The mudguard 4 is disc-shaped and is fitted onto the conveying auger 3. The mudguard 4 rotates synchronously with the conveying auger 3, and slides along the length of the frame 1 to engage with the conveying auger 3. Figure 5 The mudguard 4 is spaced apart from the frame 1, and a discharge channel for sludge discharge is provided between the mudguard 4 and the frame 1. When the drive assembly 8 is started, the drive assembly 8 can drive the conveying auger 3 to rotate. The conveying auger 3 drives the mudguard 4 to rotate. The conveying auger 3 conveys the sludge. When the conveying auger 3 conveys the sludge to the point where it is close to the discharge hopper 12, the sludge can enter the discharge channel and fall through the discharge channel to the bottom of the housing 10, and finally be discharged through the hole at the bottom of the housing 10 and enter the discharge hopper 12.

[0046] Reference Figure 3 , Figure 4 and Figure 5 The mudguard 4 is equipped with a crushing device 5, which is used to crush the lumpy sludge passing through the discharge channel. There are three sets of crushing devices 5 on the side of the mudguard 4. The crushing device 5 includes a crushing rod 51 for crushing the lumpy sludge and an adjusting component 52 for driving the crushing rod 51 to move. One end of the crushing rod 51 is rotatably engaged with the mudguard 4, and the crushing rod 51 is arranged along the radial direction of the mudguard 4. When the conveying auger 3 drives the mudguard 4 to rotate, it drives the crushing rod 51 to rotate. During the rotation of the crushing rod 51, the adjusting component 52 drives the crushing rod 51 to rotate, thereby crushing the lumpy sludge passing through the discharge channel.

[0047] Reference Figure 3 , Figure 4 and Figure 8The adjusting assembly 52 includes a mounting bracket 521 fixedly mounted on the mudguard 4, a torsion spring 522 disposed within the mounting bracket 521, and a protrusion 523 disposed on the frame 1 for driving the crushing rod 51 away from the mudguard 4 to crush the lumpy sludge. The mounting bracket 521 is a hollow cylindrical structure. A rotating shaft is fixedly mounted on the crushing rod 51 and rotatably fitted within the mounting bracket 521. The central axis of the rotating shaft is parallel to the axis of rotation of the crushing rod 51. One end of the torsion spring 522 is fixedly connected to the mounting bracket 521, and the other end is fixedly connected to the rotating shaft on the crushing rod 51. The protrusion 523 is used to drive the crushing rod 51 to reset. It is located near the bottom of the housing 10 of the frame 1. Multiple protrusions 523 are spaced along the central axis of the mudguard 4 on the frame 1. The protrusion 523 is provided with an arc-shaped surface 524. The arc-shaped surface 524 is inclined away from the feed hopper 11 along the rotation direction of the mudguard 4. The crushing rod 51 is rotatably fitted with a rotating wheel 511 that matches the arc-shaped surface 524 on the side near the protrusion 523. The crushing rod 51 provides rotational support for the rotating wheel 511. The rotation axis of the rotating wheel 511 is perpendicular to the rotation axis of the crushing rod 51.

[0048] Reference Figure 3 , Figure 4 and Figure 8 When the conveying auger 3 rotates, it drives the mudguard 4 to rotate synchronously. The rotation of the mudguard 4 drives the crushing device 5 to rotate. When the mudguard 4 drives the crushing rod 51 to rotate to the protrusion 523, the crushing rod 51 drives the rotating wheel 511 to rotate along the arc surface 524 of the protrusion 523. At this time, the protrusion 523 pushes the crushing rod 51 to rotate away from the discharge channel and compresses the torsion spring 522. As the rotating wheel 511 gradually rotates along the protrusion 523, the crushing rod 51 gradually rotates away from the discharge channel. When the rotating wheel 511 moves away from the protrusion... After the block 523 rotates out, the torsion spring 522 releases its elastic restoring force, causing the shaft of the crushing rod 51 to rotate. This, in turn, causes the crushing rod 51 to rotate closer to the discharge channel, breaking down the lumpy sludge at the discharge channel. The lumpy sludge is then broken into smaller pieces and discharged through the hole at the bottom of the housing 10. As the crushing rod 51 passes through multiple protrusions 523 in sequence, it rotates multiple times, enabling continuous crushing of the lumpy sludge and preventing sludge blockage at the discharge channel, thereby improving the efficiency of subsequent sludge treatment.

[0049] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7A flushing device 6 is provided on the crushing rod 51. The flushing device 6 is used to flush the area of ​​the conveying auger 3 near the discharge hopper 12. The flushing device 6 includes a high-pressure nozzle 61 for flushing the sludge on the conveying auger 3 near the discharge hopper 12, a water supply mechanism for supplying water to the high-pressure nozzle 61, and a rotating assembly 62 for driving the high-pressure nozzle 61 to rotate. The high-pressure nozzle 61 is provided on the crushing rod 51. The water supply mechanism includes a water supply pipe 63 for supplying water to the high-pressure nozzle 61 and a water supply assembly for supplying water to the water supply pipe 63. The water supply pipe 63 can be made of elastic material. One end of the water supply pipe 63 is connected to the high-pressure nozzle 61, and the water supply assembly includes a water storage cavity set in the mudguard 4 and a water supply component for supplying water to the water storage cavity. The water supply component can be a water pump. One end of the water supply pipe 63 is connected to the water storage cavity. When the high-pressure nozzle 61 needs to work, the water supply component is activated to deliver the flushing water to the water storage cavity. The flushing water enters the high-pressure nozzle 61 through the water supply pipe 63 and is used after being sprayed out by the high-pressure nozzle 61.

[0050] Among them, reference Figure 3 , Figure 4 , Figure 6 and Figure 7 The rotating assembly 62 includes a fixed rack 621 mounted on the frame 1 and a rotating gear 622 disposed on the crushing rod 51. The fixed rack 621 is fixedly connected to the housing 10 and is arranged along the axial direction of the conveying auger 3. The crushing rod 51 is provided with a rod fixedly connected to the rotating gear 622, and the rotating gear 622 meshes with the fixed rack 621. When the mudguard 4 slides closer to the housing 10, the mudguard 4 can drive the rotating gear 622 to move. At the same time, due to the meshing of the rotating gear 622 and the fixed rack 621, the rotating gear 622 rotates, and the rotating gear 622 drives the crushing rod 51. The crushing rod 51 rotates, and the end of the crushing rod 51 away from the mudguard 4 rotates away from the housing 10. When the mudguard 4 slides, the discharge channel between the mudguard 4 and the frame 1 becomes larger. At the same time, the crushing rod 51 drives the high-pressure nozzle 61 to rotate towards the position of the conveying auger 3 near the discharge hopper 12. After the crushing rod 51 drives the high-pressure nozzle 61 to rotate, the water supply is activated to deliver the flushing water to the water storage chamber. The flushing water enters the high-pressure nozzle 61 through the water supply pipe 63. After being sprayed out by the high-pressure nozzle 61, it flushes the position of the conveying auger 3 near the discharge hopper 12. The sludge generated by the flushing passes through the discharge channel and is discharged from the hole at the bottom of the housing 10.

[0051] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7The frame 1 is equipped with a moving device 7, which includes a sliding sleeve 71 for driving the mudguard 4 to slide and a sliding assembly 72 for driving the sliding sleeve 71 to slide. The sliding sleeve 71 is rotatably engaged with the mudguard 4 and is slidably engaged with the conveying auger 3 along the length of the frame 1. When the sliding assembly 72 drives the sliding sleeve 71 to slide, it can drive the mudguard 4 to slide, thereby driving the crushing rod 51 to slide.

[0052] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7 The sliding assembly 72 includes a sliding frame 721 fixedly connected to the sliding sleeve 71 and a driver 722 for driving the sliding frame 721 to slide. The driver 722 is directly a hydraulic cylinder, and the cylinder body of the driver 722 is fixedly installed on the housing 10 of the frame 1. The output end of the driver 722 is fixedly connected to the sliding frame 721. When the driver 722 is started, the output shaft of the driver 722 drives the sliding frame 721 to slide. The sliding frame 721 drives the sliding sleeve 71 to slide. When the sliding sleeve 71 slides, it can drive the mudguard 4 to slide and adjust. When the mudguard 4 slides closer to the housing 10, the mudguard 4 can drive the rotating gear 6 to rotate. 22 moves, and due to the meshing of the rotating gear 622 and the fixed rack 621, the rotating gear 622 rotates, which drives the crushing rod 51 to rotate. The end of the crushing rod 51 away from the mudguard 4 rotates in a direction away from the housing 10. When the mudguard 4 slides away from the housing 10, the mudguard 4 can drive the rotating gear 622 to move. At the same time, due to the meshing of the rotating gear 622 and the fixed rack 621, the rotating gear 622 rotates, which drives the crushing rod 51 to rotate. The end of the crushing rod 51 away from the mudguard 4 rotates in a direction closer to the housing 10, thus resetting.

[0053] The implementation principle of the sludge dewatering machine of the present invention is as follows: When sludge needs to be dewatered, the sludge is first added to the feed hopper 11. The sludge enters the end of the conveying pipe 2 near the feed hopper 11 from the feed hopper 11. At the same time, the drive assembly 8 is started to drive the conveying auger 3 to rotate. The conveying auger 3 conveys the sludge. During the process of conveying the sludge to the discharge hopper 12 in the conveying pipe 2, it is gradually squeezed by the conveying shaft of the conveying auger 3. The water in the sludge is gradually squeezed out and discharged from the drain hole at the bottom of the conveying pipe 2. Finally, it enters the frame 1 for subsequent processing. The sludge continues to be conveyed with the conveying auger 3 and enters the shell 10.

[0054] When the conveying auger 3 rotates, it drives the mudguard 4 to rotate synchronously. The rotation of the mudguard 4 drives the crushing device 5 to rotate. When the mudguard 4 drives the crushing rod 51 to rotate to the protrusion 523, the crushing rod 51 drives the rotating wheel 511 to rotate along the arc surface 524 of the protrusion 523. At this time, the protrusion 523 pushes the crushing rod 51 to rotate away from the discharge channel and compresses the torsion spring 522. As the rotating wheel 511 gradually rotates along the protrusion 523, the crushing rod 51 gradually rotates away from the discharge channel. When the rotating wheel 511 rotates from the protrusion 523... After discharge, the torsion spring 522 releases its elastic restoring force, causing the shaft of the crushing rod 51 to rotate, which in turn causes the crushing rod 51 to rotate closer to the discharge channel, and crushes the blocky sludge from the discharge channel. The blocky sludge becomes smaller sludge and is discharged from the hole at the bottom of the housing 10. As the crushing rod 51 passes through multiple protrusions 523 in sequence, the crushing rod 51 rotates multiple times, which can continuously crush the blocky sludge. The smaller sludge enters the discharge hopper 12 after passing through the hole at the bottom of the housing 10 for further processing, completing the sludge dewatering operation.

[0055] When it is necessary to clean the sludge in the space formed by the conveying auger 3 near the discharge hopper 12 and the conveying pipe 2, the driver 722 is started first. The output shaft of the driver 722 drives the sliding frame 721 to slide. The sliding frame 721 drives the sliding sleeve 71 to slide. When the sliding sleeve 71 slides, it can drive the mudguard 4 to slide and adjust. When the mudguard 4 slides closer to the housing 10, the mudguard 4 can drive the rotating gear 622 to move. At the same time, due to the meshing of the rotating gear 622 and the fixed rack 621, the rotating gear 622 rotates. The rotating gear 622 drives the crushing rod 51 to rotate, and the end of the crushing rod 51 away from the mudguard 4 rotates away from the housing 10.

[0056] Simultaneously, as the mudguard 4 slides, the discharge channel between the mudguard 4 and the frame 1 widens. At the same time, the crushing rod 51 drives the high-pressure nozzle 61 to rotate towards the position of the conveying auger 3 near the discharge hopper 12. After the crushing rod 51 drives the high-pressure nozzle 61 towards the position of the conveying auger 3 near the discharge hopper 12, the water supply component is activated, and the water supply component delivers flushing water to the water storage chamber. The flushing water enters the high-pressure nozzle 61 through the water supply pipe 63, and after being sprayed out by the high-pressure nozzle 61, it flushes the position of the conveying auger 3 near the discharge hopper 12. The sludge generated by flushing is discharged from the hole at the bottom of the shell 10 after passing through the discharge channel.

[0057] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
