Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a wastewater treatment device for enhanced biological denitrification. Background Technology

[0002] Against the backdrop of water resource protection and water pollution control, nitrogen pollution has become one of the key issues restricting the improvement of water quality. If nitrogen-containing wastewater is discharged directly without effective treatment, it will lead to eutrophication of receiving water bodies, causing a series of ecological problems such as the proliferation of algae, depletion of dissolved oxygen, and death of aquatic organisms. It may also threaten drinking water safety through groundwater infiltration.

[0003] Before biological denitrification of wastewater, pre-filtration of the wastewater is required. However, existing filtration equipment generates residue that needs to be collected by staff during pre-filtration, as the residue cannot be removed automatically. This affects the wastewater filtration efficiency, increases the wastewater treatment time, and also increases costs. Therefore, a wastewater treatment device for enhanced biological denitrification is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment device for enhanced biological denitrification, in order to solve the problems mentioned in the background art.

The first filter collection plate and the second filter collection plate are rotatably connected to the outside of the rotating shaft, and the first filter collection plate and the second filter collection plate are symmetrically arranged. The first filter collection plate and the second filter collection plate are arranged in a V-shape, and at the same time, the first filter collection plate and the second filter collection plate are rotated downward to arrange in an inverted V-shape.

[0006] As a further improvement to this technical solution, each of the driving components includes a first square driving rod, a second square driving rod, a first connecting rod, and a second connecting rod. The first square driving rod and the second square driving rod are rotatably connected to a rotating shaft. The first connecting rod and the second connecting rod are respectively fixedly connected to one side of the first square driving rod and the second square driving rod at a position away from the rotating shaft. The first connecting rod and the second connecting rod are respectively slidably connected in two corresponding arc-shaped sliding grooves. The other end of the first connecting rod and the second connecting rod are respectively fixedly connected to one side of the first filter collection plate and the second filter collection plate.

[0007] As a further improvement to this technical solution, a first extrusion hole and a second extrusion hole are respectively provided at the middle position of one side of the first square drive rod and the second square drive rod, and the first extrusion hole and the second extrusion hole are arranged symmetrically.

[0008] As a further improvement to this technical solution, each drive assembly also includes a mounting plate base plate, which is fixedly connected to one side of the filter housing. An electric telescopic cylinder is fixedly installed on the top side of the mounting plate base plate. An umbrella-shaped extrusion strip is fixedly connected to the piston rod end of the electric telescopic cylinder. Extrusion rods are fixedly connected to one side of the umbrella-shaped extrusion strip near both ends.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In wastewater treatment equipment used for enhanced biological denitrification, existing filtration devices cannot automatically remove filtered residue. Two drive components rotate the first and second filter collection plates on the outside of a rotating shaft. When the first and second filter collection plates are arranged in a V-shape, they collect residue from the wastewater. When they are arranged in an inverted V-shape, the residue between the first and second filter collection plates is discharged through the two filter hoppers. This solves the problem of residue collection for workers, improves filtration efficiency, and reduces waste. Attached Figure Description

[0016] Please see Figures 1-4 As shown, this embodiment provides a wastewater treatment device for enhanced biological denitrification, including a filter housing 100. The filter housing 100 has arc-shaped sliding grooves 200 on both sides, and the two arc-shaped sliding grooves 200 are symmetrically arranged. The filter housing 100 is provided with a filter collection assembly 300 and a drive assembly 400 on both sides. The filter collection assembly 300 includes a rotating shaft 301, a first filter collection plate 302 and a second filter collection plate 303. The rotating shaft 301 is fixedly connected to the inner walls of both sides of the filter housing 100, and the two ends of the rotating shaft 301 pass through the two inner walls of the filter housing 100 respectively. The first filter collection plate 302 and the second filter collection plate 303 are rotatably connected to the outside of the rotating shaft 301, and the first filter collection plate 302 and the second filter collection plate 303 are symmetrically arranged. The first filter collection plate 302 and the second filter collection plate 303 are arranged in a V-shape, and at the same time, the first filter collection plate 302 and the second filter collection plate 303 are rotated downward to arrange in an inverted V-shape.

[0017] In practical applications, the filter housing 100 forms the skeleton of the wastewater treatment equipment. The arc-shaped sliding grooves 200 on both sides of the filter housing 100 guide the first filter collection plate 302 and the second filter collection plate 303 in the filter collection assembly 300. The rotating shaft 301 ensures the rotation of the first filter collection plate 302 and the second filter collection plate 303. Under the action of the first filter collection plate 302 and the second filter collection plate 303, the residue in the wastewater can be filtered, and the residue can be collected and guided out.

[0018] Please see Figures 1-4 As shown, each drive assembly 400 includes a first square drive rod 401, a second square drive rod 402, a first connecting rod 403, and a second connecting rod 404. The first square drive rod 401 and the second square drive rod 402 are rotatably connected to the rotation shaft 301. The first connecting rod 403 and the second connecting rod 404 are respectively fixedly connected to the first square drive rod 401 and the second square drive rod 402 at positions away from the rotation shaft 301. The first connecting rod 403 and the second connecting rod 404 are respectively slidably connected in two corresponding arc-shaped sliding grooves 200. The other ends of the first connecting rod 403 and the second connecting rod 404 are respectively fixedly connected to the first filter collection plate 302 and the second filter collection plate 303 on one side. The first square drive rod 401 and the second square drive rod 402 are respectively provided with a first extrusion hole 405 and a second extrusion hole 406 at the middle position of one side, and the first extrusion hole 405 and the second extrusion hole 406 are symmetrically arranged. Each drive assembly 400 also includes a mounting plate base plate 407, which is fixedly connected to one side of the filter housing 100. An electric telescopic cylinder 408 is fixedly installed on the top side of the mounting plate base plate 407. An umbrella-shaped extrusion strip 409 is fixedly connected to the piston rod end of the electric telescopic cylinder 408. An extrusion rod 411 is fixedly connected to one side of the umbrella-shaped extrusion strip 409 near both ends. The two extrusion rods 411 slide in the first extrusion hole 405 and the second extrusion hole 406 respectively.

[0019] In practical applications, when in the filtration or residue collection state, two electric telescopic cylinders 408 work together to push two umbrella-shaped extrusion bars 409 vertically upward. The umbrella-shaped extrusion bars 409 extrude the first square drive rod 401 and the second square drive rod 402 through the first extrusion hole 405 and the second extrusion hole 406 of the two extrusion rods 411, causing the first square drive rod 401 and the second square drive rod 402 to rotate outside the rotating shaft 301. At the same time, the first square drive rod 401 and the second square drive rod 402 drive the first filter collection plate 302 and the second filter collection plate 303 to rotate outside the rotating shaft 301, so that the second filter collection plate 303 is V-shaped on the rotating shaft 301. In this way, wastewater can be filtered or residue can be collected.

[0020] When the residue is being discharged, two electric telescopic cylinders 408 work together to push two umbrella-shaped extrusion bars 409 vertically downward. The umbrella-shaped extrusion bars 409 extrude the first square drive rod 401 and the second square drive rod 402 through the first extrusion hole 405 and the second extrusion hole 406 of the two extrusion rods 411, respectively. This causes the first square drive rod 401 and the second square drive rod 402 to rotate outside the rotating shaft 301. At the same time, the first square drive rod 401 and the second square drive rod 402 drive the first filter collection plate 302 and the second filter collection plate 303 to rotate outside the rotating shaft 301. This causes the second filter collection plate 303 to form an inverted V shape on the rotating shaft 301. The residue will slide out along the surface of the first filter collection plate 302 and the second filter collection plate 303, thereby achieving the effect of slag discharge.

[0021] Please see Figures 1-2 As shown, filter hoppers 500 are fixedly installed on both sides of the filter housing 100, and the two filter hoppers 500 are arranged symmetrically. Mounting plates 600 are fixedly connected to both sides of the filter housing 100 near the top side, and each mounting plate 600 has a mounting hole 700 in the middle of the top side.

[0022] In practical applications, the two filter hoppers 500 can guide the residue to facilitate its discharge, and the mounting holes 700 on the mounting plates 600 on both sides of the filter housing 100 facilitate the installation of the wastewater treatment equipment.
