Description

Technical Field

[0001] This utility model relates to the field of wastewater sedimentation technology, and more specifically, to an inclined plate sedimentation device with self-cleaning function. Background Technology

[0002] High-concentration suspended solids wastewater refers to water bodies with a significantly higher content of suspended solid particles than ordinary wastewater. Sources of high-concentration suspended solids wastewater include tailings from mining operations, dust removal wastewater from steel plants, and food processing wastewater. Inclined plate sedimentation tanks are specialized equipment that accelerates the settling and separation of suspended solids by adding a large number of inclined plates to the traditional horizontal flow sedimentation tank.

[0003] When using the inclined plates in existing inclined plate sedimentation tanks, particulate matter easily accumulates on the surface of the plates, which reduces the sedimentation and separation efficiency and thus affects the quality of the effluent. Therefore, it is necessary to manually clean the inclined plates periodically, which affects continuous operation. In addition, traditional backwashing requires an additional water source, which is not only energy-intensive but also has unstable results. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning inclined plate sedimentation device, comprising a sedimentation tank and a support frame, wherein the top of the support frame is fixedly connected to the sedimentation tank, an inlet pipe is fixedly connected to one side of the sedimentation tank, an outlet pipe is provided at the top of the inlet pipe and is fixedly installed on the other side of the sedimentation tank, two fixed blocks and multiple inclined plates are fixedly connected inside the sedimentation tank, and a cleaning assembly is provided between the multiple inclined plates, the cleaning assembly comprising two side frames, multiple second stepper motors, multiple second lead screws, multiple moving plates, multiple flexible scrapers and multiple second slide bars, the opposite sides of the two side frames are fixedly connected to the sedimentation tank, the multiple second stepper motors are fixedly installed inside one of the side frames, and the output shaft ends of the multiple second stepper motors are respectively fixedly connected to the multiple second lead screws, the multiple moving plates are respectively threadedly connected to the multiple second lead screws, and the bottom ends of the multiple moving plates are respectively fixedly connected to the multiple flexible scrapers.

[0006] Furthermore, the top ends of the plurality of second slide rods are fixedly connected to another side frame, and the bottom ends of the plurality of second slide rods respectively penetrate the plurality of movable plates.

[0007] As can be seen, in the above technical solution, the second slide bar restricts the rotation of the moving plate.

[0008] Furthermore, a threaded piston is threadedly connected at the center of the bottom end of the sedimentation tank.

[0009] As can be seen, in the above technical solution, rotating the threaded piston and moving it away from the sedimentation tank can discharge the particulate matter inside the sedimentation tank.

[0010] Furthermore, a water outlet weir is provided on one side of the water outlet pipe. The water outlet weir is fixedly installed inside the sedimentation tank. An adjustment assembly is provided on the water outlet weir. The adjustment assembly includes a baffle, two side plates, a first lead screw, a first stepper motor, a first slide rod, and a shim.

[0011] Furthermore, the bottom end of the baffle extends into the interior of the outlet weir, and the two side plates are respectively movably sleeved on the first lead screw and the first slide rod, and the opposite sides of the two side plates are fixedly connected to the baffle. The top end of the first lead screw is fixedly connected to the end of the output shaft of the first stepper motor, the top end of the first slide rod is fixedly connected to the sedimentation tank, and the first stepper motor is fixedly installed on the top of the sedimentation tank.

The operation is simple and does not require stopping the machine or manually using a high-pressure water gun for cleaning. At the same time, the cleaning effect of particles is good.

[0017] 2. This utility model uses a first stepper motor to drive the first lead screw to rotate. The first lead screw can drive the two side plates and the baffle to move downward.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Refer to the instruction manual appendix Figure 1-3This embodiment of an inclined plate sedimentation device with self-cleaning function includes a sedimentation tank 1 and a support frame 4. The top of the support frame 4 is fixedly connected to the sedimentation tank 1. A water inlet pipe 6 is fixedly connected to one side of the sedimentation tank 1. A water outlet pipe 5 is provided at the top of the water inlet pipe 6 and is fixedly installed on the other side of the sedimentation tank 1. Two fixing blocks 8 and multiple inclined plates 11 are fixedly connected inside the sedimentation tank 1. A cleaning component 9 is arranged between the multiple inclined plates 11. The cleaning component 9 includes two side frames 901, multiple second stepper motors 902, and multiple second... The system includes a lead screw 903, multiple movable plates 904, multiple flexible scrapers 905, and multiple second slide bars 906. The opposite sides of the two side frames 901 are fixedly connected to the sedimentation tank 1. Multiple second stepper motors 902 are fixedly installed inside one of the side frames 901, and the output shaft ends of the multiple second stepper motors 902 are respectively fixedly connected to the multiple second lead screws 903. The multiple movable plates 904 are respectively threaded to the multiple second lead screws 903, and the bottom ends of the multiple movable plates 904 are respectively fixedly connected to the multiple flexible scrapers 905.

[0027] Furthermore, the top ends of multiple second slide rods 906 are fixedly connected to another side frame 901, and the bottom ends of multiple second slide rods 906 respectively pass through multiple movable plates 904. A threaded piston 7 is threadedly connected at the center of the bottom end of the sedimentation tank 1.

[0028] Furthermore, a weir 10 is provided on one side of the outlet pipe 5. The weir 10 is fixedly installed inside the sedimentation tank 1. An adjustment assembly 3 is provided on the weir 10. The adjustment assembly 3 includes a baffle 301, two side plates 302, a first lead screw 303, a first stepper motor 304, a first slide rod 305, and a gasket 306. The bottom end of the baffle 301 extends into the interior of the weir 10. The two side plates 302 are respectively movably sleeved on the first lead screw 303 and the first slide rod 305, and the opposite sides of the two side plates 302 are fixedly connected to the baffle 301. The top end of the first lead screw 303 is fixedly connected to the end of the output shaft of the first stepper motor 304. The top end of the first slide rod 305 is fixedly connected to the sedimentation tank 1. The first stepper motor 304 is fixedly installed on the top of the sedimentation tank 1. The gasket 306 is fixedly sleeved on the outside of the baffle 301, and the outside of the gasket 306 is in contact with the weir 10.

[0029] Furthermore, a transparent plate 2 is fixedly embedded in the front side of the sedimentation tank 1, wherein the transparent plate 2 serves to facilitate observation of the position of the baffle 301.

[0030] When the water level in the sedimentation tank 1 rises to the height of the outlet weir 10, the clear water will flow over the weir and finally be discharged through the outlet pipe 5. The first stepper motor 304 is started, and the first stepper motor 304 drives the first lead screw 303 to rotate. Since one side plate 302 is threadedly connected to the first lead screw 303, and the other side plate 302 cooperates with the first slide rod 305 to restrict the rotation of the baffle 301, the first lead screw 303 can drive the two side plates 302 and the baffle 301 to move downward. Similarly, the first stepper motor 304 can reverse to drive the baffle 301 to move upward. The position of the baffle 301 can be adjusted according to the needs, which can directly change the effective height of the clear water zone. At the same time, the gasket 306 can improve the sealing between the baffle 301 and the outlet weir 10. The structure is simple and easy to use. The position of the baffle 301 can be observed through the transparent plate 2.

[0031] The usage method of this embodiment is as follows:

[0032] In use, the sedimentation tank 1 is supported by the support frame 4. Wastewater enters the sedimentation tank 1 through the inlet pipe 6. Multiple inclined plates 11 increase the settling area and improve separation efficiency. Finally, the clean water is discharged through the outlet pipe 5, forming a complete water channel. The second stepper motor 902 is started, which drives the second lead screw 903 to rotate. Since the moving plate 904 is threadedly connected to the second lead screw 903, and the second slide rod 906 restricts the rotation of the moving plate 904, the second lead screw 903 can drive the moving plate 904 to move downward, thereby driving the flexible scraper 905 to move downward. The flexible scraper 905 scrapes away the particles accumulated on the inclined plates 11. It is worth noting that the flexible scraper 905 is made of silicone and nylon composite material with a serrated edge design. When it moves on the surface of the inclined plate 11, it generates micro-vibration, which enhances the peeling effect. Similarly, the second stepper motor 902 can reverse to drive the flexible scraper 905 to move upward, and clean the other inclined plates 11 in the same way. The operation is simple and does not require manual cleaning with a high-pressure water gun without stopping the machine. At the same time, it has a good effect on cleaning particles. The cleaned particles fall to the bottom of the sedimentation tank 1. By rotating the threaded piston 7 and moving it away from the sedimentation tank 1, the particles in the sedimentation tank 1 can be discharged. It is worth noting that the second lead screw 903 is a high-strength lead screw, which can prevent particles from damaging the second lead screw 903.
