Description

Sludge pre-sedimentation device with intelligent monitoring and regulation functions Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sludge pre-sedimentation device with intelligent monitoring and regulation functions. Background Technology

[0002] Sludge pre-sedimentation is an important step in achieving solid-liquid separation. In wastewater treatment, sludge is a complex mixture composed of suspended solids, organic matter, microorganisms, etc. Through pre-sedimentation, the solid particles and water in the sludge can be initially separated, which facilitates subsequent treatment processes.

[0003] However, existing sludge settling equipment typically uses sludge pumps to clean the sludge during use. This method cannot clean the sludge in a timely manner, and the settling effect decreases when the equipment continues to be used. Furthermore, the flow of water can affect the sedimentation of the sludge. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to clean sludge in a timely manner, reduced settling effect during continued use, and the impact of water flow on sludge sedimentation. The invention proposes a sludge pre-sedimentation device with intelligent monitoring and adjustment functions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sludge pre-sedimentation device with intelligent monitoring and regulation functions includes a sedimentation tank, the bottom of which is conical, and an inlet pipe for water intake and a drain pipe for drainage connected to the outer wall of the sedimentation tank.

[0007] The bottom of the sedimentation tank is fixedly provided with a guide cylinder, and the top outer wall of the guide cylinder is rotatably fitted with a rotating ring. The bottom of the rotating ring is fixedly provided with four connecting frames arranged in a ring array around the guide cylinder. The two corresponding connecting frames are respectively connected to the inlet pipe and the outlet pipe. The outer wall of the guide cylinder has two second rectangular openings corresponding to the connecting strips. The bottom of the connecting strips is connected to multiple collection cylinders. The sedimentation tank is provided with two bottom plates, which are respectively connected to two sets of collection cylinders to seal the bottom of the collection cylinders.

[0008] A sealing plate is fixed inside the guide cylinder to seal the bottom end of the guide cylinder;

[0009] The outer wall of the guide cylinder is provided with a first rectangular opening for discharging sludge.

[0010] The adjustment mechanism is located inside the settling tank and uses the gravity of the sludge to adjust the position of the two sets of connecting frames.

[0011] In one possible design, the adjustment mechanism includes a support plate fixedly installed inside the settling tank, a motor fixedly installed on the top of the support plate, a spiral conveying roller rotatably installed through the top of the support plate and the sealing plate, the top end of the spiral conveying roller being fixedly connected to the output end of the motor, a connecting strip being fixedly sleeved on the outer wall of the spiral conveying roller, the connecting strip being fixedly installed on the top of the rotating ring, and a monitoring component for monitoring the weight of sludge being installed inside the settling tank.

[0012] In one possible design, the monitoring component includes two support bars, the two ends of which are fixedly connected to the guide cylinder and the adjacent side of the sedimentation tank, respectively. A pressure sensor is provided on the top of the support bar, and the base plate is fixedly installed on the output end of the pressure sensor. A controller is fixedly installed on the outer wall of the sedimentation tank, and the motor and the pressure sensor are both connected to the controller through wires.

[0013] In one possible design, at least two guide rods are slidably provided through the top of the support bar, and the top ends of the two guide rods are fixedly connected to the corresponding base plate.

[0014] In one possible design, an extension tube is slidably provided at the bottom end of the collecting cylinder, and the bottom end of the extension tube abuts against the bottom plate.

[0015] In one possible design, the bottom of the settling tank is fixed with multiple evenly distributed support legs.

[0016] Beneficial effects:

[0017] In this invention, the sludge pre-sedimentation device with intelligent monitoring and adjustment functions achieves efficient sludge settling and centralized collection through a unique settling tank design and collection cylinder layout. The conical design at the bottom of the settling tank helps sludge accumulate towards the center, while the collection cylinder further improves sludge collection efficiency.

[0018] In this utility model, the sludge pre-sedimentation device with intelligent monitoring and adjustment function can monitor the weight of sludge in real time through the monitoring component. When the sludge accumulates to a certain level, the controller automatically starts the adjustment mechanism to realize the automatic discharge of sludge. This function not only improves work efficiency, but also reduces manual intervention, reduces operation difficulty and cost, and can improve the sedimentation efficiency of sludge.

[0019] In this utility model, the sludge pre-sedimentation device with intelligent monitoring and adjustment functions achieves stable sludge conveying and discharge through the coordinated action of the connecting strip and the collection cylinder, driven by a motor to the spiral conveying roller and rotating ring. At the same time, the design of the guide rod and the extension pipe enhances the stability and reliability of the device, ensuring smooth long-term operation.

[0020] This invention achieves efficient sludge settling, intelligent monitoring, and automatic discharge regulation through its unique design. This device not only improves the efficiency and accuracy of sludge treatment but also reduces the difficulty and cost of manual operation. At the same time, it enables remote monitoring and management through an intelligent control system, enhancing the stability and reliability of the device. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Referring to Figures 1-4, the sludge pre-sedimentation device includes: a sedimentation tank 1, the bottom of which is designed to be conical to facilitate the collection and discharge of sludge. The outer wall of the sedimentation tank 1 is connected to an inlet pipe 2 for water intake and a drain pipe 3 for water discharge.

[0029] A guide cylinder 10 is fixedly installed through the bottom of the sedimentation tank 1. A rotating ring 15 is rotatably fitted on the outer wall of the top of the guide cylinder 10. Four connecting frames 6 are fixedly connected to the bottom of the rotating ring 15, and these four connecting frames 6 are arranged in a circular array around the guide cylinder 10. Among them, two connecting frames 6 correspond to the inlet pipe 2 and the outlet pipe 3, respectively, to facilitate subsequent water flow and sludge treatment operations.

[0030] Two second rectangular openings 17, corresponding to the connecting strip 16, are formed on the outer wall of the guide cylinder 10. Multiple collection cylinders 12 are connected to the bottom of the connecting strip 16; these collection cylinders 12 are used to collect the settled sludge. Inside the settling tank 1, two bottom plates 13 are installed, each corresponding to one of the two sets of collection cylinders 12, to seal the bottom of the collection cylinders 12 and prevent sludge leakage.

[0031] To seal the bottom of the guide cylinder 10, a sealing plate 18 is fixedly installed inside the guide cylinder 10. At the same time, a first rectangular opening 11 for discharging sludge is also opened on the outer wall of the guide cylinder 10.

[0032] To achieve intelligent monitoring and adjustment functions for the sludge pre-sedimentation device, an adjustment mechanism is installed. This mechanism includes a support plate 4 fixedly installed inside the sedimentation tank 1, with a motor 5 fixedly mounted on the top of the support plate 4. A spiral conveying roller 19 is rotatably mounted through the top of the support plate 4 and the sealing plate 18, with the top end of the spiral conveying roller 19 fixedly connected to the output end of the motor 5. A connecting strip 16 is fixedly sleeved on the outer wall of the spiral conveying roller 19, and this connecting strip 16 is also fixedly mounted on the top of the rotating ring 15. Thus, when the motor 5 starts, it can drive the spiral conveying roller 19 and the rotating ring 15 to rotate, thereby adjusting the position of the connecting frame 6 and the collection cylinder 12, and accelerating the discharge of sludge from the sedimentation tank 1.

[0033] To achieve intelligent monitoring of sludge weight, a monitoring component was installed. This component includes two support bars 14, whose ends are fixedly connected to the guide cylinder 10 and the adjacent side of the settling tank 1, respectively. A pressure sensor 20 is installed on the top of the support bars 14, and a base plate 13 is fixedly mounted on the output end of the pressure sensor 20. Thus, when sludge settles in the collection cylinder 12, its weight is transmitted to the pressure sensor 20 through the base plate 13, thereby achieving real-time monitoring of the sludge weight. A controller 9 is fixedly installed on the outer wall of the settling tank 1. The motor 5 and the pressure sensor 20 are both connected to the controller 9 via wires to achieve intelligent control.

[0034] This application can be used in the field of wastewater treatment, or in other fields applicable to this application.

[0035] Example 2

[0036] Referring to Figure 1-Figure, an improvement is made based on Embodiment 1: a sludge pre-sedimentation device with intelligent monitoring and adjustment functions is applied to the field of sewage treatment. In order to improve the stability of the base plate 13 during the lifting process, at least two guide rods 21 are slidably arranged through the top of the support bar 14. The top ends of the two guide rods 21 are fixedly connected to the corresponding base plate 13.

[0037] In addition, the bottom of the collection cylinder 12 has been improved by sliding an extension tube 22. The bottom end of the extension tube 22 abuts against the bottom plate 13, and a sealing ring is also provided at the bottom end of the extension tube 22. In this way, when the bottom plate 13 is raised or lowered, the extension tube 22 can be raised or lowered together, thereby ensuring that the bottom end of the collection cylinder 12 is always in close contact with the bottom plate 13 and preventing sludge leakage.

[0038] Finally, to enhance the stability of the entire device, multiple evenly distributed support legs 8 are fixedly installed at the bottom of the settling tank 1, which also increases the height of the bottom of the guide cylinder 10.

[0039] In this application, during use, sewage enters the two connecting frames 6 through the inlet pipe 2 and is discharged through the drain pipe 3. During the flow of sewage, the sludge in the water will settle downwards under its own gravity and settle into the collection cylinder 12. When there is a lot of sludge, the gravity will increase, which can drive the bottom plate 13 to move downwards. At the same time, the extension pipe 22 can move downwards under the action of gravity, ensuring that the extension pipe 22 and the bottom plate 13 are always sealed. When the pressure monitored by the pressure sensor 20 is greater than the set value, the controller 9 controls the motor 5 to start. The rotation of the motor 5 can drive the spiral conveying roller 19 to rotate. The rotation of the spiral conveying roller 19 can drive the rotating ring 15 to rotate through the connecting strip 16. The rotation of the rotating ring 15 can drive the four connecting strips 16 to rotate around the guide cylinder 10, so that they change positions. When the extension pipe 22 is away from the bottom plate 13, the sludge in the extension pipe 22 can automatically fall into the sedimentation tank 1 and be discharged into the guide cylinder 10 through the first rectangular opening 11. During the rotation of the spiral conveying roller 19, the downward flow of sludge can be accelerated.

[0040] However, as is well known to those skilled in the art, the working principles and wiring methods of motor 5 and controller 9 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0041] 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.
