Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sludge treatment equipment, and in particular to a sludge storage tank for sludge treatment. Background Technology
[0002] Large amounts of sludge are generated during wastewater treatment, industrial production, and urban pipeline maintenance. Before the sludge is dewatered or subsequently utilized for resource recovery, it usually needs to be temporarily stored and regulated using sludge storage tanks.
[0003] Sludge is a solid-liquid mixture with unstable physical properties. During static storage, the solid particles in the sludge are prone to settling due to gravity, accumulating at the bottom of the tank and gradually hardening. This settling not only reduces the effective volume of the tank, but more seriously, it can block the discharge port at the bottom, making it difficult to discharge the sludge and seriously affecting the continuity of subsequent processing procedures.
[0004] To address the issue of sludge settling, existing technologies often incorporate agitation devices inside storage tanks to keep the sludge in a fluid state through mechanical agitation. However, the transmission mechanisms of these agitation devices, such as gearboxes, bearings, or rotating shaft seals, often require components to pass through the tank or be close to the sludge in order to drive the agitator inside the tank.
[0005] Sludge typically has high moisture content, strong corrosiveness, and may contain abrasive particles. This causes the transmission components of the mixing device to be exposed to harsh working conditions for a long time, making them prone to corrosion, wear, and sealing failure. This leads to frequent failures of the mixing device, which not only greatly reduces the operational reliability of the equipment and significantly shortens its service life, but also results in high maintenance costs and difficult on-site repairs.
[0006] Therefore, this utility model proposes a sludge storage tank for sludge treatment to overcome the shortcomings of the prior art. Utility Model Content
[0007] In view of the problems in the prior art, such as the sludge in sludge storage tanks used for sludge treatment easily settling and hardening at the bottom of the tank, causing blockage of the discharge port, and the transmission components of the stirring mechanism being easily corroded by sludge, resulting in low reliability, this utility model aims to provide a sludge storage tank for sludge treatment with an improved structure that can effectively solve the above problems.
[0008] This utility model provides a sludge storage tank for sludge treatment, comprising: a main body, and a motor fixedly installed on the top of the main body; as well as a large gear, a first small gear, a second small gear, a third small gear, a rotating plate, a stirring paddle, a partition plate, and a connecting plate.
[0009] The large gear is fixedly connected to the output shaft of the motor; the first small gear is meshed with the large gear; the second small gear is coaxially fixedly connected to the first small gear; the third small gear is meshed with the second small gear; the rotating plate is coaxially fixedly connected to the third small gear; and the stirring paddle is fixedly connected to the bottom of the rotating plate and extends into the main body.
[0010] Furthermore, the partition is fixedly connected to the inner wall of the main body, and the partition separates the second and third pinions from the stirring paddle; the connecting plate is fixed above the partition and is used to rotatably support the first, second, and third pinions.
[0011] Preferably, a fixing ring is fixedly connected to the outer wall of the main body, and multiple support legs are fixedly connected to the outer wall of the fixing ring. Anti-slip plates are fixedly connected to the bottom of the support legs. This structural combination provides stable physical support for the main body and increases the contact area with the ground through the anti-slip plates.
[0012] Preferably, a trapezoidal groove is fixedly connected to the bottom of the main body. The trapezoidal groove has a conical structure that is larger at the top and smaller at the bottom, which is used to guide the sludge to gather towards the center under the action of gravity. A connecting pipe is connected to the bottom of the trapezoidal groove, and the connecting pipe serves as a pipe for discharging sludge.
[0013] Preferably, a sealing plate is fixedly connected to the top opening of the main body. The sealing plate covers the gap between the large gear and the opening of the main body. The sealing plate is used to seal the gap between the motor output shaft and the top of the tank, effectively preventing sludge odor from leaking out or external debris from entering the tank.
[0014] Preferably, the storage tank further includes a support plate extending from the inner wall of the main body and fixedly supporting the partition from bottom to top, thereby enhancing the structural rigidity and load-bearing capacity of the partition and ensuring stability under sludge pressure.
[0015] Preferably, the first pinion and the second pinion are coaxially fixedly connected by a rotating rod. The connecting plate has a first rotating through hole for rotatably mounting the rotating rod to achieve coaxial power transmission between the first pinion and the second pinion.
[0016] Preferably, the partition plate has a second rotating through hole. The rotating shaft of the pinion three passes through the connecting plate and the second rotating through hole in sequence, and is fixedly connected to the rotating plate downward. This structure realizes the accurate transmission of power from the upper transmission cavity to the rotating plate in the lower sludge receiving cavity.
[0017] Preferably, the large gear, small gear one, connecting plate, small gear two, small gear three, and stirring paddle are all made of corrosion-resistant materials or have undergone anti-corrosion treatment to resist the chemical corrosion of sludge and ensure that the stirring transmission mechanism has a long service life.
[0018] This utility model has the following beneficial effects: 1. This utility model, by setting up a multi-stage gear transmission mechanism consisting of a motor-driven large gear, small gear one, small gear two, and small gear three, drives the rotating plate and stirring paddle to rotate, continuously agitating the sludge inside the main body. This solves the problem in the prior art where sludge easily settles and clumps during storage, thus clogging the bottom discharge port, and achieves the effect of preventing sludge settling and ensuring smooth discharge.
[0019] 2. This utility model separates the upper gear transmission mechanism from the lower sludge containing cavity by setting a partition, and fixes and supports the transmission mechanism and the partition by connecting plate and support plate. This solves the problem of corrosion and wear of the stirring transmission components in the prior art due to direct contact with sludge, and achieves the effect of protecting the transmission mechanism and improving the reliability and service life of the device.
[0020] 3. This utility model, by designing the bottom of the main body as a truncated trough structure that is larger at the top and smaller at the bottom, and connecting it with the bottom connecting pipe, uses gravity to guide the sludge to gather towards the center, which solves the problem of material accumulation dead corners and incomplete discharge in the existing technology of flat-bottomed tanks, and achieves the effect of improving discharge efficiency and reducing residue.

The stirring paddle 14 is completely located inside the sludge receiving cavity; As a preferred embodiment, please refer to Figure 1 To improve the overall stability of the device, a fixing ring 2 is fixedly connected to the outer wall of the main body 1. Multiple support legs 3 are fixedly connected to the outer wall of the fixing ring 2. Anti-slip plates 4 are fixedly connected to the bottom of the support legs 3. The anti-slip plates 4 are used to increase the contact area with the ground and maintain the stability of the device.
[0027] As a preferred embodiment, please refer to Figure 1 and Figure 3 In order to facilitate the discharge of sludge and prevent material accumulation, a trapezoidal trough 5 is fixedly connected to the bottom of the main body 1. The trapezoidal trough 5 is shaped with a larger top and a smaller bottom to facilitate the collection of sludge under the action of gravity.

[0028] As a preferred embodiment, please refer to Figure 1 and Figure 3 In order to prevent sludge odor from leaking out and debris from entering the interior of the main body 1, a sealing plate 17 is fixedly connected to the top opening of the main body 1.

[0030] As a preferred embodiment, please refer to Figure 3 and Figure 4 In order to achieve coaxial transmission between pinion 9 and pinion 11, pinion 9 and pinion 11 are coaxially fixedly connected by a rotating rod, and the connecting plate 10 is provided with a first rotating through hole for rotating the rotating rod.
[0031] As a preferred embodiment, please refer to Figure 3 In order to transmit power from the transmission chamber to the sludge containing chamber, the partition 16 is provided with a second rotating through hole.

[0033] Specifically, Working principle: When motor 7 starts, the output shaft of motor 7 drives the fixedly connected large gear 8 to rotate. The large gear 8 meshes with the small gear 9, thereby driving the small gear 9 to rotate. Since pinion 9 and pinion 11 are coaxially fixedly connected by a rotating rod, the rotation of pinion 9 synchronously drives pinion 11 to rotate. Pinion 11 meshes and drives pinion 3 to rotate. This transmission process is completed in the transmission cavity above partition 16. During this process, connecting plate 10 is fixed above partition 16 and used to rotate and support the rotating shafts of pinion 9, pinion 11 and pinion 3 12, ensuring smooth transmission. The rotating shaft of the pinion 12 passes through the partition 16 and is fixedly connected to the rotating plate 13 downwards. The rotation of the pinion 12 then drives the rotating plate 13 and the stirring paddle 14 fixedly connected to the bottom of the rotating plate 13 to rotate synchronously. The stirring paddle 14 stirs the sludge in the sludge receiving cavity below the partition 16. The continuous stirring of the agitator 14 effectively prevents the sludge inside the main body 1 from settling and caking, ensuring that the sludge maintains its fluidity. Under the action of gravity, the sludge collects along the stepped groove 5 and is smoothly discharged through the connecting pipe 6, solving the problem of discharge port blockage caused by sludge settling. At the same time, the partition 16 completely isolates the transmission mechanism from the sludge, preventing the gear set from being corroded, while the support plate 15 provides stable structural support for the partition 16.
