Description

Technical Field

[0001] This utility model relates to the technical field of sewage and sludge treatment devices, and in particular to an automatic correction device for sewage and sludge dewatering filter cloth. Background Technology

[0002] Wastewater contains many impurities such as sludge, so sludge and wastewater need to be separated in wastewater treatment. Belt filter presses are generally used for sludge dewatering in large-flow, low-viscosity wastewater. Through a continuous physical pressing process, the solid and liquid in the wastewater are separated, and the sludge cake falls into a designated area for collection for subsequent treatment.

[0003] In a belt filter press, wastewater is squeezed by the rolling of a dewatering filter cloth. The water in the wastewater is filtered out through the dewatering filter cloth, while the sludge remains on the dewatering filter cloth and is transferred to the drive area. In actual use, wear of the rollers and uneven distribution of sludge can cause the dewatering filter cloth to shift, which may lead to the dewatering filter cloth separating from the drive shaft, a decrease in dewatering effect, and accelerated wear of the dewatering filter cloth.

[0004] Therefore, how to provide an automatic correction device for sewage sludge dewatering filter cloth is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] refer to Figures 1-5 In this embodiment, the device includes a drive shaft 1, a transmission shaft 2, a filter cloth body 3, and a side fixing plate 4. One end of the side fixing plate 4 is fixedly connected to a mounting frame 5. The transmission shaft 2 is rotatably connected inside the mounting frame 5. The mounting frame 5 is mainly for mounting the transmission shaft 2. The drive shaft 1 is rotatably connected to the surface of the side fixing plate 4 at a position away from the mounting frame 5. Both ends of the filter cloth body 3 are movably sleeved on the surfaces of the drive shaft 1 and the transmission shaft 2. A power motor connected to the drive shaft 1 is also provided on one side of the side fixing plate 4. This power motor mainly drives the drive shaft 1 to rotate and is a prior art component, which will not be described in detail here. There are two sets of side fixing plates 4 and two sets of mounting frames 5, which are symmetrically arranged on the transmission shaft 2. Therefore, there are also two sets of corresponding components on the mounting frame 5.

[0025] The mounting frame 5 is equipped with a movable component 6 located inside the drive shaft 2. The movable component 6 includes a movable block 12, a guide rod 13, a disc spring 14, and a positioning spring 15. The movable block 12 is movably connected inside the movable chamber 10. The guide rod 13 is fixedly connected to the side of the movable block 12 away from the movable correction component 9. The disc spring 14 is movably sleeved on the surface of the drive shaft 2 inside the movable chamber 10, with one end of the disc spring 14 movably connected to the surface of the movable block 12 and the other end of the disc spring 14 movably connected to the inner wall of the movable chamber 10. The other end of the guide rod 13 extends to the outside of the mounting frame 5. The spring is movably sleeved on the surface of the guide rod 13 inside the movable chamber 10. Both ends of the spring are movably connected to the side of the movable block 12 away from the correction component 9 and the inner wall of the movable chamber 10 away from the correction component 9, respectively. The movable block 12 is rotatably sleeved on the end face of the drive shaft 2 via a bearing.

[0026] In specific implementation, the movable block 12 moves inside the movable chamber 10. It should be noted that the movable block 12 moves back and forth along the movable chamber 10. Each movable block 12 corresponds to two disc springs 14, with the two disc springs 14 respectively located on both sides of the movable block 12. Figure 4 As shown, the movable block 12 is fitted onto the end face of the transmission shaft 2 for stability. When the movable block 12 moves, the guide rod 13 also moves. The positioning spring 15 on the guide rod 13 applies pressure to the movable block 12, causing the movable block 12 to press tightly against the correction assembly 9.

[0027] refer to Figures 1-5 In this embodiment, a deviation transmission component 7 is provided on the side of the mounting frame 5 near the filter cloth body 3. One end of the deviation transmission component 7 is close to the outer side of the filter cloth body 3. The deviation transmission component 7 includes a deviation wheel 16, a deviation shaft 17, a lever 18, a switch 19, and a movable pressing component 20. The deviation shaft 17 is rotatably connected to the side of the mounting frame 5. The deviation wheel 16 is fixedly connected to the end face of the deviation shaft 17. The lever 18 is fixedly connected to the side of the deviation wheel 16 near the mounting frame 5 and close to the outermost position. The switch 19 is located on the top of the mounting frame 5 and is connected to the drive assembly 8 through a wire. The movable pressing component 20 is located on the top of the mounting frame 5 and is movably sleeved on the outside of the switch 19. The movable pressing component 20, the switch 19, and the lever 18 are in the same plane.

[0028] The movable pressing component 20 includes an outer fixed base 21, a movable cover 22, and a pressing spring component 23. The outer fixed base 21 is fixedly connected to the top of the mounting frame 5 at the position corresponding to the switch 19. The movable cover 22 is movably connected inside the outer fixed base 21, with the top end of the movable cover 22 extending above the outer fixed base 21. The pressing spring component 23 is movably disposed inside the outer fixed base 21 and movably sleeved on the outside of the switch 19. The two ends of the pressing spring component 23 are movably connected to the lower surface of the movable cover 22 and the bottom of the inner wall of the outer fixed base 21, respectively.

[0029] In specific implementation, when the filter cloth body 3 deviates from its designated path, it will come into contact with the deviation wheel 16. The friction of the filter cloth body 3 will drive the deviation wheel 16 to rotate, causing the deviation wheel 16 to rotate through the deviation shaft 17. The rotation of the deviation wheel 16 will drive the lever 18 to rotate. After the lever 18 rotates to the movable pressing member 20, the rotational force of the lever 18 will press the movable cover 22, causing the movable cover 22 to move downward and squeeze the pressing spring member 23. After the pressing spring member 23 is pressed, it will retract. At this time, the movable cover 22 will press on the switch 19 to open the switch 19. After the switch 19 is opened, the drive assembly 8 will be powered on and work.

[0030] refer to Figures 1-5 In this embodiment, a positioning ring 24 is provided on the top of the mounting frame 5 corresponding to the position of the switch 19. The positioning ring 24 is movably sleeved on the side of the switch 19, and the pressing spring 23 is movably sleeved on the outside of the positioning ring 24.

[0031] It should be noted that the positioning ring 24 is set at this position mainly to limit the position of the pressing spring 23, so as to prevent the pressing spring 23 from sliding on the movable cover 22 and the outer fixed seat 21 when pressed, thus affecting the control of the switch 19.

[0032] refer to Figures 1-5 In this embodiment, a drive assembly 8 is provided on the outer side of the mounting frame 5. The deviation transmission component 7 is connected to the drive assembly 8 through a wire. The drive assembly 8 includes a drive motor 25 and a first conical drive gear 26. The drive motor 25 is fixedly installed on the outer side of the mounting frame 5. The output shaft of the drive motor 25 extends into the interior of the adjustment chamber 11. The first conical drive gear 26 is located inside the adjustment chamber 11 and is fixedly connected to the output shaft of the drive motor 25.

[0033] In practice, opening switch 19 will power on drive assembly 8. It should be noted that drive motor 25 is powered by an external power source, such as a municipal power supply system or other power sources. The electrical energy will be transferred to drive motor 25 after passing through switch 19. After switch 19 is opened, drive motor 25 starts working. The start of drive motor 25 will drive the first bevel drive gear 26 to rotate. The rotation of the first bevel drive gear 26 will drive the correction assembly 9 to perform correction work.

[0034] refer to Figures 1-5 In this embodiment, a correction component 9 driven by the drive component 8 is provided inside the mounting frame 5 at the position corresponding to the drive component 8. One end of the correction component 9 extends to the surface of the movable component 6. The correction component 9 includes a fixing ring 27, a square through groove 28, an adjusting screw 29, a square rod 30, a bevel gear 31, and an internal thread knob 32. The fixing ring 27 is fixedly connected to the inner wall of the adjusting chamber 11. The square through groove 28 is opened on the inner side wall of the adjusting chamber 11 to connect the adjusting chamber 11 and the movable chamber 10. The square rod 30 is movably connected inside the square through groove 28. One end of the square rod 30 extends into the interior of the movable chamber 10 and abuts against the side of the movable block 12. The other end of the direction rod extends into the interior of the adjusting chamber 11 and is fixedly connected to the end face of the adjusting screw 29. The internal thread knob 32 is rotatably connected to the inner wall of the fixing ring 27 through a bearing. The bevel gear 31 is fixedly sleeved on the side of the internal thread knob 32. The bevel gear 31 meshes with the first bevel drive gear 26.

[0035] In practice, the rotation of the first conical drive gear 26 drives the rotation of the conical gear 31, which in turn drives the rotation of the internal thread knob 32. The rotation of the internal thread knob 32 then moves the adjusting screw 29. The movement of the adjusting screw 29 moves the square rod 30 within the square through groove 28. The movement of the square rod 30 then moves the movable block 12 within the movable chamber 10. The movement of the movable block 12 changes the orientation of the drive shaft 2. By changing the orientation of the drive shaft 2, the misaligned filter cloth body 3 is corrected. Once the orientation of the drive shaft 2 is adjusted to correct the misalignment of the filter cloth body 3, it separates from the misalignment wheel 16. After separation, the movable block 16 is pushed upward by the elastic force of the pressing spring 23. Cover 22 is moved away from switch 19, so that switch 19 is closed without being pressed, thereby cutting off power to drive motor 25. Drive shaft 2 maintains the adjusted posture and works. It should be noted that the two sets of correction components 9 are symmetrically arranged at both ends of drive shaft 2. Whichever side of filter cloth body 3 deviates will contact the deviation wheel 16 on that side and drive it to rotate. To reiterate, when lever 18 is pressed by movable cover 22, it is prevented from rotating. At this time, deviation wheel 16 also does not rotate, so filter cloth body 3 is positioned by friction between deviation wheel 16 and lever 18. This achieves the effect of continuous pressing. Only after filter cloth body 3 is corrected will it separate from deviation wheel 16.

[0036] refer to Figures 1-5 In this embodiment, the installation frame 5 is provided with an active chamber 10 and an adjustment chamber 11, the active component 6 is provided inside the active chamber 10, and the correction component 9 is provided inside the adjustment chamber 11.

[0037] This allows the activity component 6 and the correction component 9 to be set in two different areas, achieving the purpose of separate settings.

[0038] The method of using this utility model is as follows:

[0039] During operation, when the filter cloth body 3 deviates from its designated position, it will contact the deviation wheel 16 and rotate it through friction. The deviation wheel 16 rotates through the deviation shaft 17, which will drive the lever 18 to rotate to the position of the movable pressing part 20 and press the movable cover 22. Then, the movable cover 22 is pressed down to press the switch 19, which opens the switch 19. At this time, the drive component 8 is powered on and will drive the movable component 6 to move inside the movable chamber 10 through the correction component 9. The movement of the movable component 6 will drive the drive shaft 2 to move to adjust the posture of the movable shaft. After the posture of the movable shaft is adjusted, it will perform a correction operation on the filter cloth body 3. After the filter cloth body 3 is corrected, it will separate from the deviation wheel 16. When the deviation wheel 16 is separated, the lever 18 will be pushed upward by the pushing force of the pressing spring part 23. In this way, the movable cover 22 will separate from the switch 19. After the switch 19 is turned off, the drive component 8 stops working. In this way, the positions of the movable component 6 and the correction component 9 are adjusted to the posture of the drive shaft 2, ensuring the effectiveness of the correction.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
