Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment machinery technology, and in particular to a wastewater treatment device. Background Technology

[0002] Wastewater treatment equipment refers to a series of machines and facilities used to treat wastewater generated from domestic, commercial, or industrial activities. These devices remove pollutants from wastewater through physical, chemical, and biological methods, ensuring that the discharged water meets environmental standards and reducing environmental impact. Common wastewater treatment equipment includes screens, grit chambers, sedimentation tanks, bioreactors, filters, and disinfection devices. These devices work together to effectively purify water and achieve water resource recycling. With technological advancements, modern wastewater treatment equipment places greater emphasis on energy efficiency and intelligence to meet increasingly stringent environmental requirements.

[0003] Chinese utility model patent publication number CN 221777678 U discloses a wastewater treatment device that uses a power component to drive a rotating component, causing a fixed plate to move along a chain. The fixed plate and two arc-shaped plates scrape away the floating sludge layer on the water surface in the separation zone, preventing scum from affecting the subsequent flocculant buoyancy process. However, during the scum removal process, the fixed plate is not permeable, so each time the fixed plate operates, some water is pushed into the sludge tank in a wave-like manner. Furthermore, the scum has a high water content, which hinders subsequent scum treatment. Therefore, improvements are necessary. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a sewage treatment device.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A wastewater treatment device includes a body, within which, from left to right, are arranged a reaction zone, a flotation zone, a separation zone, a sludge tank, and a clear water zone. A transition zone is provided between the separation zone and the sludge tank. The lower part of the separation zone is connected to the clear water zone via a pipe. Two parallel rotating shafts are rotatably mounted on the upper end of the separation zone. Sprockets are fixedly connected to both ends of the rotating shafts within the separation zone, and chains meshing with the sprockets on the same side are wound around them. One of the rotating shafts is driven by a servo motor. The device also includes multiple comb plates arranged at intervals along the chain, with the chains fixedly connected to the corresponding sides of the comb plates at their respective ends. A conveyor with a lower left end and a higher right end is provided in the transition zone. The right end of the conveyor is connected to the body via a bracket, and the left end extends into the liquid surface of the separation zone.

[0007] Preferably, the conveyor includes a drive roller rotatably connected to the support frame, a driven roller rotatably connected to the machine body, a conveyor belt wound around the drive roller and the driven roller, and a servo motor for driving the drive roller.

[0008] Preferably, the conveyor belt has multiple baffles spaced apart on its surface, and the baffles are arranged along the width direction of the conveyor belt.

[0009] Preferably, the conveyor belt is a perforated belt.

[0010] Preferably, a water guide plate is inclinedly arranged below the conveyor, and baffles are provided on the front and rear sides of the water guide plate. The left end of the water guide plate extends into the separation zone; the left end of the water guide plate is fixedly connected to the machine body, and the right end is fixedly connected to the support.

[0011] Preferably, the comb plate is made of rubber.

[0012] Preferably, the sludge tank is provided with an inclined guide plate, and the machine body is provided with a discharge port at the lower end of the guide plate.

[0013] The above technical solution has the following advantages:

[0014] This invention employs a comb-tooth plate to push scum, working in conjunction with a conveyor belt to lift and transport the scum. During the comb-tooth plate pushing process, wastewater is almost entirely prevented from overflowing into the sludge tank in a wave-like manner, thus reducing wastewater spillage. Furthermore, the inclined conveyor belt effectively filters out some of the wastewater from the scum, which not only helps reduce the water content of the scum but also significantly reduces the complexity and cost of subsequent scum treatment, improving the efficiency and environmental friendliness of the entire process.

Detailed Implementation

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] As shown in the attached figure, a wastewater treatment device includes a body 1. From left to right, the body 1 contains a reaction zone 2, a flotation zone 3, a separation zone 4, a sludge tank 5, and a clear water zone 6. A transition zone 7 is provided between the separation zone 4 and the sludge tank 5, providing space for the arrangement of a conveyor 14. The lower part of the separation zone 4 is connected to the clear water zone 6 via a pipe 8. Two parallel rotating shafts 9 are rotatably mounted on the upper end of the separation zone 4. Sprockets 10 are fixedly connected to both ends of each rotating shaft 9 within the separation zone 4, and chains 11 mesh with the sprockets on the same side. One rotating shaft 9 is connected to a servo motor 12. The device also includes multiple comb plates 13 spaced along the chains 11, with the chains 11 fixedly connected to the corresponding ends of each comb plate 13. A conveyor 14, with a lower left end and a higher right end, is provided in the transition zone 7. The right end of the conveyor 14 is connected to the body 1 via a bracket 15, and the left end extends into the liquid surface of the separation zone 4.

[0028] As a specific technical solution in this embodiment, the conveyor 14 includes a drive roller 16 rotatably connected to the support 15, a driven roller 17 rotatably connected to the machine body 1, a conveyor belt 18 winding around the drive roller 16 and the driven roller 17, and a servo motor 19 driving the drive roller 16. In this embodiment, the left end of the conveyor belt 18 is close to the side of the sprocket 10, and the comb plate 13 pushes the floating scum to the left end of the conveyor belt 18 and is conveyed to the right by the conveyor belt 18.

[0029] As a further improvement to this embodiment, a plurality of baffles 20 are spaced apart on the surface of the conveyor belt 18, and the baffles 20 are arranged along the width direction of the conveyor belt 18. The baffles 20 can improve the adhesion of scum and improve the reliability of scum conveying.

[0030] As a further improvement to this embodiment, the conveyor belt 18 is a perforated belt to further enhance its filtration capacity, allowing more wastewater to be separated from the scum. The conveyor belt 18 operates at a low speed to ensure effective wastewater separation.

[0031] As a further improvement to this embodiment, a water guide plate 21 is inclinedly arranged below the conveyor 14, and baffles 22 are provided on the front and rear sides of the water guide plate 21. The left end of the water guide plate 21 extends into the separation zone 4. The left end of the water guide plate 21 is fixedly connected to the machine body 1, and the right end is fixedly connected to the support 15. The water guide plate 21 can return the sewage separated by the conveyor belt 18 to the separation zone 4.

[0032] As a further improvement in this embodiment, the comb plate 13 is made of rubber. Both sides of the comb plate 13 can contact the side wall of the separation zone 4. At the same time, when the comb plate 13 moves to the left end of the conveyor belt 18, it can also contact the surface of the conveyor belt 18 to improve the pushing effect of the scum.

[0033] As a further improvement to this embodiment, an inclined guide plate 23 is provided inside the sludge tank 5, and a discharge port 24 is provided on the machine body 1 at the lower end of the guide plate 23. The scum conveyed by the conveyor belt 18 falls onto the guide plate 23 from its right end and is discharged from the lower end of the guide plate 23.

[0034] The comb-shaped toothed plate 13 of this invention reduces ripples on the liquid surface within the separation zone 4. When the comb-shaped plate 15 pushes the scum, the scum is pushed onto the conveyor belt 18 for lifting and transporting. During the scum pushing process by the comb-shaped plate 13, wastewater is almost completely prevented from overflowing into the sludge tank 5 in the form of waves, thus reducing wastewater spillage into the sludge tank 5. Furthermore, the inclined design of the conveyor belt 18 effectively filters out some of the wastewater from the scum, helping to reduce the water content of the scum.

[0035] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
