Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to an industrial wastewater treatment device based on the Internet of Things. Background Technology

[0002] In industrial wastewater sedimentation, flocculants are often sprayed as a sedimentation method. Since flocculants can cause fine particles in water to aggregate into larger particles, existing technologies often use stirring to disperse the flocculants in order to improve the sedimentation effect.

[0003] During the use of flocculants, excessive stirring can cause larger particles that have already agglomerated in the water to break down into smaller particles again, thus affecting the sedimentation effect.

[0004] Therefore, there is a need to propose an industrial wastewater treatment device based on the Internet of Things to solve the above problems. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an industrial wastewater treatment device based on the Internet of Things, which solves the problem in the prior art that excessive stirring will cause large particles that have already agglomerated in the water to break into smaller particles again, thus affecting the sedimentation effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an industrial wastewater treatment device based on the Internet of Things, including a flocculation tank. The flocculation tank has an inlet and an outlet on its side wall. A filter screen is fixedly installed inside the flocculation tank. The inlet is located below the filter screen, and the outlet is located above the filter screen. A guide cylinder is fixedly connected inside the flocculation tank. The filter screen is arranged around and fixedly connected to the guide cylinder. The guide cylinder is frustum-shaped, with its long diameter end above the filter screen and its short diameter end below the filter screen. A gap is provided between the bottom wall of the guide cylinder and the bottom wall of the flocculation tank. A conical spiral plate is rotatably installed inside the guide cylinder, with the spiral plate tilting in the same direction as the guide cylinder. The outer wall of the spiral plate is slidably connected to the inner wall of the guide cylinder. The spiral plate is rotatably connected to the bottom wall of the flocculation tank via a support shaft. A stirring shaft, coaxial with the support shaft, is rotatably connected to the support shaft. The stirring shaft is located above the filter screen, and multiple stirring rods are arranged circumferentially around the axis of the stirring shaft.

[0008] Furthermore, the stirring shaft is hollow inside, and multiple connecting pipes are fixedly connected to the outer wall of the stirring shaft around the axis of the stirring shaft. The connecting pipes are connected to the inside of the stirring shaft. The stirring rod is rotatably connected to the connecting pipes. A centrifugal ball is fixedly connected to the end of the stirring rod away from the stirring shaft. Multiple discharge ports connected to the connecting pipes are provided on the stirring rod.

[0009] Furthermore, a protective filter screen that can slide along the axial direction of the stirring shaft is slidably connected to the stirring shaft. The protective filter screen can cover the long diameter end of the guide tube. An installation ring is rotatably connected to the protective filter screen. A connecting rod is hinged to the middle of the stirring shaft. The end of the connecting rod away from the stirring rod is hinged to the installation ring.

[0010] Furthermore, multiple dispersing rods are arranged circumferentially around the support shaft, with the dispersing rods located between the bottom wall of the guide tube and the bottom wall of the flocculation tank.

[0011] Furthermore, the top of the support shaft is provided with a groove that mates with the stirring shaft, and the stirring shaft is rotatably connected within the groove.

[0012] Furthermore, solenoid valves are installed in both the inlet and outlet of the water.

[0013] Furthermore, a turbidity sensor for monitoring the water quality above the filter screen is fixedly installed inside the flocculation tank.

[0014] Furthermore, a differential pressure mud level gauge for monitoring the thickness of sediment accumulation is fixedly installed below the filter screen inside the flocculation tank.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. During the continuous sedimentation of wastewater in the flocculation tank, the stirring shaft is rotated to drive the stirring rod to stir the wastewater above the filter screen, thereby dispersing the flocculant and improving the sedimentation effect. During the stirring process, the spiral plate is driven to rotate, causing the wastewater above the filter screen to flow into the guide tube and down to the bottom of the filter screen. This avoids over-stirring and causing the larger particles that have already agglomerated in the water to break down into smaller particles again, while improving the sedimentation effect of the fine particles in the wastewater above the filter screen.

[0017] 2. By setting up centrifugal balls and turbidity sensors, the stirring range can be adjusted according to water quality;

[0018] 3. By setting a hollow stirring shaft and a discharge port on the stirring rod, the flocculant is sprayed following the stirring range of the stirring rod, which improves the uniformity of flocculant spraying; or an external air-filling structure is connected to play an aeration function, further improving the uniformity of flocculant dispersion.

Detailed Implementation

[0025] like Figures 1-3 As shown, this utility model provides an industrial wastewater treatment device based on the Internet of Things, including: a flocculation tank 1, with an inlet 101 and an outlet 102 provided on the side wall of the flocculation tank 1; a filter screen 2 fixedly installed inside the flocculation tank 1, with the inlet 101 located below the filter screen 2 and the outlet 102 located above the filter screen 2; a guide cylinder 3 fixedly connected inside the flocculation tank 1, with the filter screen 2 surrounding the guide cylinder 3 and fixedly connected to the guide cylinder 3; the guide cylinder 3 is frustoconical, with its long-diameter end extending above the filter screen 2 and its short-diameter end extending to the filter screen 2. Below, and with a gap between the bottom side of the guide tube 3 and the bottom wall of the flocculation tank 1, a conical spiral plate 4 is rotatably arranged inside the guide tube 3. The inclination direction of the spiral plate 4 is consistent with the inclination direction of the guide tube 3. The outer wall of the spiral plate 4 is slidably connected to the inner wall of the guide tube 3. The spiral plate 4 is rotatably connected to the bottom wall of the flocculation tank 1 through a support shaft 401. A stirring shaft 5 is rotatably connected to the support shaft 401 and is coaxially arranged with the support shaft 401. The stirring shaft 5 is located above the filter screen 2. Multiple stirring rods 501 are arranged circumferentially on the stirring shaft 5 with the axis of the stirring shaft 5 as the center.

[0026] In this scheme, industrial wastewater enters the flocculation tank 1 through the inlet 101. The filter screen 2 prevents sludge and sediment from passing through. Then, flocculant is sprayed into the flocculation tank 1 to agglomerate fine particles in the water into larger particles. During the flocculation process, rotating the stirring shaft 5 causes the stirring rod 501 to rotate, stirring the wastewater above the filter screen 2 and dispersing the flocculant to improve the sedimentation effect. During stirring, the support shaft 401 is driven to rotate, thereby rotating the spiral plate 4, causing the wastewater above the filter screen 2 to flow along the guide tube 3 to the area below the filter screen 2. In this process, the water... Larger particles formed in the flocculation tank flow below the filter screen 2. The filter screen 2 and the spiral plate 4 restrict the flow of larger particles above the filter screen 2 to avoid excessive stirring that would cause the larger particles already formed in the water to break down into smaller particles again. At the same time, the sedimentation effect of fine particles in the wastewater above the filter screen 2 is improved. One end of the support shaft 401 extends out of the bottom wall of the flocculation tank 1 and is fixedly connected to the drive motor 403, which is fixedly installed on the bottom wall of the flocculation tank 1. The drive motor 403 drives the support shaft 401 to rotate. The support shaft 401 and the stirring shaft 5 can rotate separately. The stirring shaft 5 is driven independently by the drive mechanism located above the flocculation tank 1.

[0027] The flocculation tank 1 is equipped with a turbidity sensor (not shown in the figure) installed above the filter screen 2 to monitor the water quality above the filter screen 2. The turbidity sensor monitors the water quality above the filter screen 2 in real time and transmits the water quality signal to the control system to control the rotation efficiency of the drive motor 403 driving the support shaft 401 and the rotation efficiency of the drive mechanism driving the stirring shaft 5.

[0028] Solenoid valves (not shown in the figure) are installed in both the inlet 101 and the outlet 102. The solenoid valves are connected to the control system. When the water quality signal detected by the turbidity sensor meets the preset standard, the control system controls the solenoid valves to open, so that water flows out from the outlet 102.

[0029] In one embodiment of this utility model, the stirring shaft 5 is hollow inside, and a plurality of connecting pipes 502 are fixedly connected circumferentially around the axis of the stirring shaft 5 on the outer wall of the stirring shaft 5. The connecting pipes 502 communicate with the inside of the stirring shaft 5. The stirring rod 501 is rotatably connected to the connecting pipes 502, and a centrifugal ball 503 is fixedly connected to the end of the stirring rod 501 away from the stirring shaft 5. A plurality of discharge ports 504 communicating with the connecting pipes 502 are provided on the stirring rod 501.

[0030] In this scheme, during the rotation of the stirring shaft 5 by the control system driving the drive mechanism, the stirring rod 501 rotates along with the rotation of the stirring shaft 5. Due to the different rotation speeds, the centrifugal force generated by the centrifugal ball 503 is also different, causing the stirring rod 501 to rotate to different heights around the connecting pipe 502, thereby achieving the effect of adjusting the stirring range through water quality signals. The flocculant can be injected into the stirring shaft 5 and discharged through the discharge port 504, so that the spraying of the flocculant follows the stirring range of the stirring rod 501, improving the uniformity of flocculant spraying. In another embodiment, a certain amount of flocculant can be added to the stirring shaft 5 in advance, and then the aeration mechanism can be connected to the stirring shaft 5. By filling the stirring shaft 5 with gas, the flocculant is driven to be discharged from the discharge port 504. After the flocculant is discharged, the excess gas is discharged from the discharge port 504 to achieve the aeration function, further improving the uniformity of flocculant dispersion.

[0031] In one embodiment of this utility model, a protective filter screen 505 that can slide along the axial direction of the stirring shaft 5 is slidably connected to the stirring shaft 5. The protective filter screen 505 can cover the long diameter end of the guide tube 3. The density of the protective filter screen 505 is the same as that of the filter screen 2. An installation ring 506 is rotatably connected to the protective filter screen 505. A connecting rod 507 is hinged to the middle of the stirring rod 501. The end of the connecting rod 507 away from the stirring rod 501 is hinged to the installation ring 506.

[0032] In this scheme, when the stirring shaft 5 is stationary, the protective filter screen 505 covers the long diameter end of the guide tube 3 to prevent large particles in the guide tube 3 from flowing into the filter screen 2. When the stirring shaft 5 is rotating, the stirring rod 501 flips upward under the centrifugal force of the centrifugal ball 503, thereby driving the mounting ring 506 and the protective filter screen 505 to move upward through the connecting rod 507 to open the long diameter end of the guide tube 3. During the stirring process, the spiral plate 4 is in a rotating state, and the large particles are brought into the area below the filter screen 2 through the spiral plate 4, which facilitates sedimentation and collection.

[0033] In one embodiment of the present invention, a plurality of dispersing rods 402 are arranged circumferentially around the support shaft 401, and the dispersing rods 402 are located between the bottom wall of the guide tube 3 and the bottom wall of the flocculation tank 1.

[0034] In this scheme, when the support shaft 401 rotates, it drives the dispersing rod 402 to rotate, so as to disperse the large particles located on the bottom wall side of the guide tube 3, so as to prevent the large particles from accumulating below the guide tube 3 and affecting the water output effect of the guide tube 3.

[0035] In one embodiment of the present invention, the top of the support shaft 401 is provided with a groove 404 that cooperates with the stirring shaft 5, and the stirring shaft 5 is rotatably connected in the groove 404.

[0036] In this design, by providing a groove 404 to support the stirring shaft 5, the stability of the support shaft 401 and the stirring shaft 5 during rotation is ensured.

[0037] In one embodiment of this utility model, a differential pressure mud level gauge (not shown in the figure) for monitoring the thickness of sediment accumulation is fixedly installed below the filter screen 2 inside the flocculation tank 1.

[0038] In this scheme, when the differential pressure mud level gauge detects that the thickness of the sediment accumulation exceeds the threshold, the solenoid valve in the inlet 101 is closed, and the sediment below the filter screen 2 is cleaned.

[0039] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
