Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to an anti-clogging sludge dewatering machine for wastewater treatment. Background Technology

[0002] Wastewater often contains a large amount of water-containing sludge, with a water content as high as about 99%. Direct treatment is difficult and costly. Dewatering can reduce the water content of sludge, significantly reducing its volume, making it easier to transport and treat, and reducing treatment costs. Secondly, dewatered sludge is easier to stabilize, such as through incineration, landfill, or resource utilization, reducing the potential environmental risks of harmful substances in the sludge, lowering pathogen concentrations, reducing odors and leachate production, and preventing secondary pollution.

[0003] A search revealed that Chinese Patent Publication No. CN221544420U discloses a sludge dewatering machine for sewage treatment. When mud or foreign objects in the mud block part of the mesh holes on the filter screen, the motor can be started. The motor drives the threaded rod to rotate, and the rotation of the threaded rod drives the connecting plate to move until it moves above the blocked mesh hole. Then, the electric telescopic rod is started, and the electric telescopic rod drives the fixed plate and the guide column on the fixed plate to move downward until the guide column passes through the blocked filter hole and clears the filter hole. This device can effectively clean the blocked filter screen in a timely manner and avoid the filter screen blockage affecting normal use.

[0004] In the above technical solution, the filter holes are cleaned by controlling the guide column with an electric push rod. However, the process can only be started after the blockage occurs, resulting in a passive and delayed response. It can only clear the blockage one hole at a time. When dealing with large-area blockage, it is time-consuming and energy-intensive. Therefore, a sludge dewatering machine for sewage treatment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anti-clogging sludge dewatering machine for sewage treatment, which aims to improve the problem that the existing anti-clogging sludge dewatering machines for sewage treatment cannot actively prevent clogging by adjusting the filter holes, thus reducing the anti-clogging effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sludge dewatering machine for sewage treatment, comprising a machine body, a discharge pipe rotatably connected to the inner wall of the machine body, a fixed plate fixedly connected to the top of the discharge pipe, a filter cylinder one fixedly connected to the top of the fixed plate, a filter cylinder two provided on the outer wall of the filter cylinder one, filter holes opened on the outer wall of the filter cylinder two, a mounting frame fixedly connected to the bottom of the machine body, a motor fixedly connected to the surface of the mounting frame, a rotating shaft fixedly connected to the output end of the motor, a transmission belt driven by a transmission wheel on the rotating shaft, a guide groove opened on the outer wall of the discharge pipe, a guide block slidably connected to the inner wall of the guide groove, a fixed pipe fixedly connected to the outer wall of the guide block, a valve fixedly connected to the bottom end of the fixed pipe, a bracket fixedly connected to the outer wall of the fixed pipe, an adjustment and positioning component provided on the outer wall of the fixed plate, and a guide component provided on the surface of the fixed plate.

[0007] As a further description of the above technical solution:

[0008] The second filter cylinder is fitted onto the outer wall of the first filter cylinder, and the transmission belt is also connected to the discharge pipe via a transmission wheel.

[0009] As a further description of the above technical solution:

[0010] The adjustment and positioning assembly includes a gear ring, a support shaft rotatably connected to the top of the fixed disk, a gear fixedly connected to the outer wall of the support shaft, a knob fixedly connected to the top of the support shaft, a slide rod slidably connected to the inner wall of the support shaft, a spring fixedly connected to the outer wall of the support shaft, and a positioning block threadedly connected to the inner wall of the slide rod via a screw.

[0011] As a further description of the above technical solution:

[0012] The inner surface of the toothed ring is fixedly connected to the outer wall of the filter cylinder II, and the gear meshes with the toothed ring.

[0013] As a further description of the above technical solution:

[0014] The positioning block is arc-shaped, and its outer wall fits against the inner wall of the filter cylinder.

[0015] As a further description of the above technical solution:

[0016] The guide assembly includes an annular groove, and a slider is slidably connected to the inner wall of the annular groove.

[0017] As a further description of the above technical solution:

[0018] The annular groove is formed on the top of the fixed plate, and the top of the slider is fixedly connected to the bottom of the second filter cylinder.

[0019] As a further description of the above technical solution:

[0020] A support ring is fixedly connected to the inner wall of the machine body, and a spherical groove is provided at the bottom of the knob, with a rolling ball provided on the inner wall of the spherical groove.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the alignment of the filter holes is adjusted by the staggered rotation of the inner and outer double filter cylinders, which significantly improves the adjustment range and flexibility of the filtration accuracy and effectively prevents filter hole clogging. The unique adjustment and positioning component can realize convenient adjustment and stable locking of the filter cylinder angle to ensure stable filtration effect. Combined with the structural design of the rotating discharge pipe and the stationary fixed pipe, internal motion interference is avoided while continuously and efficiently dewatering, ensuring smooth and reliable operation of the equipment, and ultimately achieving a more efficient sludge dewatering effect and stronger anti-clogging performance.

[0023] 2. In this utility model, the support ring on the inner wall of the machine body cooperates with the rolling ball at the bottom of the knob. Through the irregular rotation of the rolling ball in the spherical groove, the knob is supported by the support ring when the filter cylinder rotates. The rolling ball also greatly reduces the friction between the knob and the support ring, reducing the knob's rotation resistance and wear, improving the smoothness of knob operation, ensuring the stable operation of the adjustment and positioning components, making the alignment and adjustment of the filter cylinder's filter holes easier, and enhancing the equipment's operational reliability and service life.

The transmission belt 18 is also connected to the discharge pipe 2 through a transmission wheel. A guide groove 19 is opened on the outer wall of the discharge pipe 2. A guide block 20 is slidably connected to the inner wall of the guide groove 19. Three sets of guide blocks 20 are provided and are equidistantly distributed around the center point of the fixed pipe 21. When the discharge pipe 2 rotates, the guide blocks 20 will slide inside the guide groove 19. A fixed pipe 21 is fixedly connected to the outer wall of the guide block 20. A valve 22 is fixedly connected to the bottom end of the fixed pipe 21. A bracket 23 is fixedly connected to the outer wall of the fixed pipe 21. The bracket 23 consists of a ring and three horizontal plates. The three horizontal plates are connected to the support legs of the machine body 1. When the discharge pipe 2 rotates, the fixed pipe 21 is in a stationary state.

[0035] Reference Figure 4 , Figure 6 , Figure 7The outer wall of the fixed disk 3 is provided with an adjustment and positioning assembly, which includes a gear ring 9, a gear 10, a support shaft 11, a knob 12, a slide rod 13, and a spring 14. The inner surface of the gear ring 9 is fixedly connected to the outer wall of the second filter cylinder 7. The top of the fixed disk 3 is rotatably connected to the support shaft 11. The outer wall of the support shaft 11 is fixedly connected to the gear 10, which meshes with the gear ring 9. The top of the support shaft 11 is fixedly connected to the knob 12, which controls the rotation of the support shaft 11. The inner wall of the support shaft 11 is slidably connected to the slide rod 13, which is composed of a set of elliptical rods, a set of discs, and a set of round rods. The elliptical rods can be inserted into the first filter cylinder 4 and the second filter cylinder 7 through the filter holes 8, and the diameter of the elliptical rods is smaller than the diameter of the intersecting filter holes 8 on the first filter cylinder 4 and the second filter cylinder 7. For example, when the filter holes 8 on the first filter cylinder 4 and the second filter cylinder 7 are intersecting, the elliptical rods... The filter body can be smoothly inserted into the filter hole 8. A spring 14 is fixedly connected to the outer wall of the support shaft 11. A positioning block 27 is threadedly connected to the inner wall of the slide rod 13 through a screw. The positioning block 27 is arc-shaped. The outer wall of the positioning block 27 fits against the inner wall of the filter cylinder 1 4. By screwing the positioning block 27 into the threaded hole of the slide rod 13, and with the elastic force of the spring 14, the positioning block 27 can fit tightly against the inner wall of the filter cylinder 1 4. After the alignment of the filter holes 8 of the filter cylinder 1 4 and the filter cylinder 2 7 is adjusted, it can provide positioning for the two. A guide component is provided on the surface of the fixed plate 3. The guide component includes an annular groove 5 and a slider 6. The annular groove 5 is opened on the top of the fixed plate 3. The slider 6 is slidably connected to the inner wall of the annular groove 5. The top of the slider 6 is fixedly connected to the bottom of the filter cylinder 2 7. When the filter cylinder 2 7 rotates, the slider 6 slides in the annular groove 5. There are three sets of sliders 6, which provide a certain support force for the filter cylinder 2 7.

[0036] Reference Figure 5 A support ring 24 is fixedly connected to the inner wall of the body 1. A spherical groove 25 is provided at the bottom of the knob 12. A rolling ball 26 is provided on the inner wall of the spherical groove 25. The spherical groove 25 is fitted onto the rolling ball 26. The rolling ball 26 can rotate irregularly inside the spherical groove 25. Several sets of spherical grooves 25 and rolling balls 26 are provided, and several sets of spherical grooves 25 and rolling balls 26 are arranged in pairs at the bottom of the knob 12. The outer surface of the rolling ball 26 can fit against the top of the support ring 24. When the filter cylinder 1 4 and the filter cylinder 2 7 rotate, the support ring 24 can provide support force to the knob 12, and the rotation of the rolling ball 26 reduces the friction between the knob 12 and the support ring 24.

[0037] Working principle: The operator rotates knob 12, which drives the support shaft 11 and the gear 10 on it to rotate. The gear 10 meshes with the gear ring 9 fixed on the outer wall of filter cylinder 2 7, thereby driving filter cylinder 2 7 to rotate relative to the fixed disk 3 and filter cylinder 1 4. When filter cylinder 2 7 rotates, the slider 6 at its bottom slides in the annular groove 5 at the top of the fixed disk 3, providing rotational support. When knob 12 is rotated to the point where the elliptical rod at the bottom of slide rod 13 can be smoothly inserted into the intersecting filter holes 8 of filter cylinder 1 4 and filter cylinder 2 7, the filter holes 8 of the two sets of filter cylinders are aligned. At this time, the arc-shaped positioning block 27 screwed into slide rod 13 is tightly attached to the filter cylinder under the elastic force of spring 14. The inner wall of filter cylinder 4 locks the relative positions of the two filter cylinders. An external conveying device puts sewage containing sludge into filter cylinder 4. The motor 16 is started, and its output shaft drives the discharge pipe 2 to rotate through the transmission wheel and transmission belt 18. The fixed plate 3, filter cylinder 4, and filter cylinder 7, which are fixedly connected to the top of the discharge pipe 2, rotate synchronously at high speed. Under the action of strong centrifugal force, the sewage is thrown out through the aligned filter holes 8, passes through the inner cavity of the machine body 1, and is finally discharged through the drain pipe on the side wall of the machine body 1, completing the dewatering. The sludge is trapped inside filter cylinder 4 and filter cylinder 7. The dewatered sludge is discharged through the discharge pipe 2, completing the entire sludge dewatering process.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
