Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank technology, specifically to an integrated device for inclined plate phosphorus removal sedimentation tank. Background Technology

[0002] In the context of rapid industrial development, many enterprises generate a large amount of industrial wastewater during production, including wastewater containing high concentrations of phosphorus. With the increasing awareness of environmental protection and the increasingly stringent environmental regulations, higher requirements have been put forward for phosphorus discharge standards in industrial wastewater. In order to ensure that the wastewater of enterprises meets the standards, a high-efficiency integrated phosphorus removal device is used to remove phosphorus from the wastewater treatment plant to ensure that the wastewater is discharged in compliance with the standards.

[0003] Traditional concrete phosphorus removal sedimentation tanks have drawbacks such as large footprint and high investment costs. Therefore, the industry is gradually exploring integrated inclined plate phosphorus removal sedimentation tank devices to save space and reduce costs through structural integration. At the same time, relying on the characteristic of increasing the sedimentation area by inclined plates, the phosphorus removal efficiency is improved, meeting the needs of enterprises for efficient and economical phosphorus removal equipment. After adding chemicals in the coagulation zone, phosphorus-containing wastewater will form phosphorus sludge particles. During the settling process on the surface of the inclined plate, these particles are prone to accumulating on the inclined plate due to particle adhesion or fluctuations in water flow velocity, forming sludge that leads to poor water flow.

[0004] Therefore, we propose an integrated inclined plate phosphorus removal sedimentation tank device to solve the above problems. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figure 1-3 As shown in the figure, an integrated device for inclined plate phosphorus removal sedimentation tank according to one embodiment of the present invention includes a phosphorus removal sedimentation tank body 1, wherein a connected sedimentation bottom chamber 14 is provided at the bottom of the cavity of the phosphorus removal sedimentation tank body 1, and a phosphorus removal agent coagulation zone 2 is provided on one side of the cavity of the phosphorus removal sedimentation tank body 1, and a phosphorus removal agent coagulation zone 2 and the phosphorus removal sedimentation tank body 1 are connected by a phosphorus removal sedimentation tank inlet pipe 6, so that the water in the phosphorus removal agent coagulation zone 2 can enter the cavity of the phosphorus removal sedimentation tank body 1 along the phosphorus removal sedimentation tank inlet pipe 6. A sludge discharge pipe 7 is provided at the bottom of the sedimentation bottom chamber 14, and the other end of the sludge discharge pipe 7 is connected to a sludge zone 8.

[0028] The top of the entire phosphorus removal sedimentation tank body 1 is covered by a top cover 15, and the top cover 15 is installed in a detachable manner and connected to the phosphorus removal sedimentation tank body 1 by side bolts. A large operating cover 16 is set at the center of the top of the top of the top cover 15, which facilitates maintenance work inside the phosphorus removal sedimentation tank body 1. The opening of the operating cover 16 can cover the phosphorus removal agent coagulation zone 2 and the cavity of the phosphorus removal sedimentation tank body 1.

[0029] Two sets of spaced-apart guide vanes 11 are installed on the surface of the top cover 15, located at the phosphorus removal agent coagulation zone 2. The top of each guide vane 11 extends upward through the top cover 15, forming a funnel structure. The bottom of each guide vane 11 extends into the bottom layer of the phosphorus removal agent coagulation zone 2, creating a cross-shaped discharge pipe at the bottom. This allows the raw materials fed into the guide vane 11 to enter the phosphorus removal agent coagulation zone 2 more evenly. Therefore, after passing through the integrated equipment, wastewater enters the phosphorus removal agent coagulation zone 2 through an interface on one side of the zone, and is then guided by the guide vane... Plate 11 can flush the phosphorus removal agent into the phosphorus removal agent coagulation zone 2 and mix it thoroughly with the wastewater. A guide tube 5 is connected to one end of the phosphorus removal sedimentation tank inlet pipe 6 that extends into the main body 1 of the phosphorus removal sedimentation tank. The guide tube 5 and the phosphorus removal sedimentation tank inlet pipe 6 are distributed in a T-shape. At the same time, multiple sets of sludge discharge bottom ports 10 are distributed at intervals at the bottom of the guide tube 5, so that the liquid flows down along the bottom of the sludge discharge bottom ports 10. It is worth noting that the internal channel of the guide tube 5 is inverted V-shaped. That is, after the water enters the center of the guide tube 5, it can move to both sides more quickly through the inclined channels on both sides, improving the smoothness of movement.

[0030] Below the guide tube 5, there is a guide plate 3 connected to the inner wall of the main body 1 of the phosphorus removal sedimentation tank. The top of the guide plate 3 is a slope, which allows the water flow to move down along the top slope of the guide plate 3. In this process, the contact area of ​​the wastewater with sedimentation space can be increased, and the sedimentation and separation of the phosphorus mud particles formed after the addition of chemicals can be accelerated. Then, the phosphorus mud particles slide down to the sedimentation bottom chamber 14 and are discharged from the sludge discharge pipe 7.

[0031] An overflow weir 4 is provided near the top of the main body 1 of the phosphorus removal sedimentation tank, and an outlet pipe 9 extending into the inside of the overflow weir 4 is installed on the top of the main body 1 of the phosphorus removal sedimentation tank. The treated water overflows into the overflow weir 4 and is discharged from the outlet pipe 9.

[0032] To clean the sludge accumulated on the top of the guide plate 3, this design includes a set of cleaning scrapers 13 covering a large lateral area of ​​the guide plate 3. The bottom of the cleaning scrapers 13 has a detachable rubber strip 17 that contacts the top of the guide plate 3. Sludge scraping is achieved by moving the detachable rubber strip 17 along the top of the guide plate 3. The top of the cleaning scrapers 13 is fixed with an upwardly protruding operating rod 18. In actual operation, the cleaning scrapers 13 can be moved by operating the operating rod 18 at the operating cover 16, thereby achieving the scraping action. To improve the stability of the cleaning scraper 13's movement, a guide rail groove 12 is provided on the inner wall of the main body 1 of the phosphorus removal sedimentation tank. One end of the cleaning scraper 13 is fixed with an insert rod that can extend into the guide rail groove 12 and slide along the guide rail groove 12. In actual operation, since the length of the cleaning scraper 13 is less than that of the guide inclined plate 3, the cleaning scraper 13 has a certain amount of room to maneuver. The end of the cleaning scraper 13 with the insert rod is inserted into the guide rail groove 12, and then the operating rod 18 is used to push the cleaning scraper 13 to move.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
