Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a sludge storage tank for sludge treatment. Background Technology

[0002] In municipal sewage treatment plants and industrial wastewater treatment workshops, sludge storage tanks can be used for the temporary storage and transfer of sludge. Sludge with high water content generated during sewage treatment is initially dewatered and then sent to the storage tank through pipelines or transportation equipment. In the sludge treatment process of industries such as chemical and food processing, the storage tanks can also be used in conjunction with chemical dosing to pre-treat the sludge, improve the efficiency of subsequent dewatering or reduce the content of heavy metals and other harmful substances, and help achieve the reduction, stabilization and harmless treatment of sludge.

[0003] In existing technologies, some sludge storage tanks are key equipment used to temporarily store sludge transported from sewage treatment plant pipelines or external sources, which is then transported to drying towers and other facilities for further processing. Their internal structure is relatively complex, making it easy for sludge to get trapped inside, which is difficult to clean thoroughly, and it is also prone to bacterial growth and odor, thus affecting the subsequent treatment effect.

[0004] However, during actual use, clogging problems are prone to occur during material feeding. When faced with sludge of different moisture content and viscosity, the sludge with poor flowability accumulates at the bottom of the tank or in the discharge pipe. Moreover, there is a lack of efficient anti-sticking measures, and the sludge easily adheres to the tank wall to form a hanging material, further reducing the flow cross section, aggravating the clogging, affecting the continuity and efficiency of sludge treatment, and increasing cleaning costs and equipment downtime risks. In response to the above problems, a sludge storage tank for sludge treatment is proposed. Utility Model Content

[0026] like Figures 1 to 4As shown, one embodiment of this utility model provides a sludge storage tank for sludge treatment, including a base plate 1, a storage tank body 2 fixedly mounted on the base plate 1, and an anti-clogging mechanism inside the storage tank body 2. The anti-clogging mechanism includes a motor 7 and a rotating shaft 10. The motor 7 is fixedly mounted on the top of the storage tank by bolts, and the rotating shaft 10 is rotatably mounted inside the storage tank body 2 by bearings. The top end of the rotating shaft 10 protrudes outside the storage tank body 2 and is connected to the output end of the motor 7 for transmission. In this embodiment, for ease of installation, a rotating rod 8 is fixedly connected to the output end of the motor 7, and a gear 9 is fixedly mounted on the rotating rod 8. A gear 11 that meshes with the gear 9 is fixedly mounted on the top end of the rotating shaft 10. When the motor 7 rotates, it drives the rotating shaft 10 to rotate. A stirring blade 12 and a support cylinder 22 are fixedly mounted on the surface of the rotating shaft 10. A scraper 23 for cleaning the inner wall of the storage tank body 2 is provided on the support cylinder 22. In this embodiment, the support cylinder 22 has an inner cavity and is vertically fixedly mounted on the rotating shaft 10.

[0027] The storage tank body 2 has a feed pipe 15 at the top and a discharge pipe 16 at the bottom. Both the feed pipe 15 and the discharge pipe 16 are equipped with valves. A clearing rod 13 extending into the discharge pipe 16 is fixed at the bottom of the rotating shaft 10. The surface of the clearing rod 13 is equipped with spiral blades 14. In this embodiment, the rotation of the rotating shaft 10 drives the clearing rod 13 and the spiral blades 14 to rotate synchronously. The spiral blades 14 assist in clearing the discharge pipe, allowing the sludge to be discharged smoothly.

[0028] A cavity 27 is provided axially inside the rotating shaft 10. The interior of the support cylinder 22 communicates with the cavity 27. A rotating rod 178 is fixedly installed inside the cavity 27. The rotating rod 178 is coaxially arranged with the rotating shaft 10. The top of the rotating rod 178 does not contact the top wall of the cavity 27, and the bottom does not contact the bottom wall of the cavity 27. The middle part of the rotating rod 178 is fixedly connected to the rotating shaft 10 through a mounting ring 26. A follower assembly is provided between the rotating rod 178 and the scraper 23. The follower assembly is slidably installed inside the support cylinder 22. One end of the follower assembly is connected to the rotating rod 178, and the other end is connected to the scraper 23.

[0029] The follower assembly includes a fixed ring 18, a first rod 19, a second rod 20, and a slider 25. Two fixed rings 18 are fixedly fitted onto the top and bottom ends of a rotating rod 178, respectively. Neither the top nor bottom end of the rotating rod 178 protrudes beyond the fixed rings 18. The slider 25 is slidably mounted inside a support cylinder 22 and located at the end of the support cylinder 22 furthest from the rotating shaft 10. A partition 24 is fixedly installed inside the support cylinder 22. A connecting rod 5 is fixedly installed on the outer side of the slider 25, penetrating the end face of the support cylinder 22. A third rod 21 is fixedly installed on the inner side of the slider 25. The other end of the connecting rod 5 is fixedly connected to a scraper 23. The other end of the third rod 21 penetrates the partition 24 and is fixedly connected to one end of the first rod 19. The other end of the first rod 19 is hinged to one end of the second rod 20, and the other end of the second rod 20 is hinged to the edge of the fixed ring 18. In this embodiment, the second rod 20 of the lower follower assembly is hinged to the bottom edge of the corresponding fixed ring 18, and the second rod 20 of the upper follower assembly is hinged to the top edge of the corresponding fixed ring 18. The hinge axes of the first rod 19 and the second rod 20, and the hinge axis of the second rod 20 and the fixed ring 18 are both parallel to the vertical direction. In this embodiment, the axes of the first rod 19 and the third rod 21 are both parallel to the axis of the support cylinder 22. With this structural design, the rotation of the fixed ring 18 can drive the scraper 23 to move radially back and forth along the rotating shaft 10. By axially spacing two fixed rings 18 on the rotating shaft 10 and correspondingly arranging two sets of follower components, the scraper 23 can be driven to move more stably. In this embodiment, when the rotating shaft 10 rotates, the rotating rod 178 and the fixed ring 18 rotate synchronously. The rotation of the fixed ring 18 causes the second rod 20 connected to it to swing. The end of the second rod 20 that is hinged to the fixed ring 18 rotates around the rotating rod 178. The end of the second rod 20 that is hinged to the first rod 19 moves radially along the rotating rod 178 while rotating horizontally. Under the action of the second rod 20, the first rod 19, the third rod 21, and the slider 25 make linear reciprocating motion along the axial direction of the support cylinder 22. That is, the scraper 23 makes reciprocating linear motion in the horizontal direction. The scraper 23 periodically and intermittently contacts the inner wall of the storage tank body 2. Compared to traditional designs where the scraper 23 is always in close contact with the tank wall, causing rapid wear of both the scraper 23 and the tank wall due to prolonged rotation, this structural design significantly reduces friction time and extends tool life through periodic intermittent contact. Furthermore, the instantaneous impact force generated by intermittent contact can more effectively peel off stubborn adhering material. When the scraper 23 detaches from the tank wall, rotational resistance decreases, the load on the motor 7 decreases, and energy consumption decreases. At the same time, when the scraper 23 detaches from the tank wall, the centrifugal force tends to throw off the slurry adhering to the scraper 23, giving the scraper 23 a certain self-cleaning ability.

[0030] The storage tank is equipped with a feed screen cylinder 28, and the rotating shaft 10 is fixedly installed on the feed screen cylinder 28. In this embodiment, the stirring blade 12 and the feed screen cylinder 28 are located between the upper and lower support cylinders 22. The stirring blade 12 is located inside the feed screen cylinder 28, and the feed pipe 15 is aligned with the feed screen cylinder 28. When the motor 7 drives the rotating shaft 10 to rotate, the feed screen cylinder 28 and the stirring blade 12 rotate synchronously with the rotating shaft 10. The feed screen cylinder 28 filters impurities, reducing the possibility of blockage when the sludge is discharged.

[0031] A filter box 6 is provided on one side of the storage tank body 2 on the bottom plate 1. An exhaust pipe 4 is installed between the storage tank body 2 and the filter box 6 to facilitate the exhaust of gas from the storage tank body 2. The filter box 6 is equipped with multiple layers of filter screens to purify the exhaust gas and prevent environmental pollution.

[0032] The storage tank body 2 is equipped with an observation window 3, which allows operators to check the storage volume and processing status of the sludge in the tank at any time.

[0033] Working principle:

[0034] The motor 7 drives the rotating shaft 10 to rotate, which in turn drives the stirring blades 12, the feed screen cylinder 28, the support cylinder 22, and the rotating rod 178 to rotate synchronously. The stirring blades 12 and the support cylinder 22 both stir the sludge in the tank, preventing pipe blockage caused by sludge sticking and clumping. The rotation of the rotating rod 178 causes the slider 25 to reciprocate linearly along the radial direction of the rotating shaft 10 through the first rod 19, the second rod 20, and the third rod 21. That is, the scraper 23 periodically scrapes off the material adhering to the inner wall of the storage tank. After the sludge is filtered for impurities by the feed screen cylinder 28, it reaches the bottom of the storage tank body 2. When discharging, the valve in the discharge pipe 16 opens, and the unblocking rod 13 and the spiral blades 14 rotate synchronously with the rotating shaft 10, allowing the filtered sludge to be discharged smoothly. Harmful gases generated in the storage tank are discharged through the exhaust pipe 4 and then purified by the filter box 6 before being discharged.
