Threaded holes are provided on the upper surfaces of both the water supply pipe and the return pipe. Arc-shaped pipes are fixedly installed on the outer surfaces of both the water supply pipe and the return pipe.

[0004] While the above scheme has many advantages, it also has disadvantages: since there are multiple arc-shaped pipes, and these multiple arc-shaped pipes are connected to the water supply pipe and the return pipe respectively by threaded connection, the operation is not only more troublesome, but also cannot achieve the effect of quick connection. Therefore, an improved design of a wastewater treatment energy recovery device is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment energy recovery device, comprising a wastewater tank, with L-shaped connecting frames on both sides of the top of the wastewater tank, and brackets on the top of the two L-shaped connecting frames. A water supply pipe is fixedly connected inside one bracket, and a return water pipe is fixedly connected inside the other bracket.

Multiple reinforcing rods are fixedly connected to one side of the L-shaped mounting bracket, and one end of each of the multiple reinforcing rods is fixedly connected to the L-shaped connecting frame. The multiple reinforcing rods provide support for the two L-shaped connecting frames and can improve the stability of the L-shaped connecting frame.

[0008] Preferably, the top of the L-shaped connecting frame has multiple arc-shaped grooves longitudinally arranged, and a limiting groove is formed inside the arc-shaped groove. A limiting block is fixedly connected to the outside of the arc-shaped pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This application utilizes two rotating rods, each equipped with a second bevel gear, to rotate. The four second bevel gears mesh with four first bevel gears, which in turn drive four threaded rods to rotate.

Each of the two L-shaped connecting frames 3 has a bracket 4 on its top. A water supply pipe 5 is fixedly connected inside one bracket 4, and a return water pipe 6 is fixedly connected inside the other bracket 4. Multiple connecting pipes 7 are fixedly connected to the outside of the water supply pipe 5 and the return water pipe 6. An arc-shaped pipe 8 is fitted on the outer side of one end of the connecting pipe 7. Multiple arc-shaped grooves 301 are longitudinally opened on the top of the L-shaped connecting frame 3. A limiting groove 302 is formed inside the arc-shaped groove 301. A limiting block 80 is fixedly connected to the outer side of the arc-shaped pipe 8. The arc-shaped pipe 8 is set inside the arc-shaped groove 301, and the limiting block 80 is set inside the limiting groove 302. A valve 70 is installed on the outer side of the connecting pipe 7. A sealing gasket is installed on the outer side of one end of the connecting pipe 7. The sealing gasket is in contact with one end of the arc-shaped pipe 8. A recovery pipe 9 is installed at the bottom end of the arc-shaped pipe 8. Multiple recovery pipes 9 are grouped in pairs. A bend 10 is installed between the multiple groups of recovery pipes 9. Multiple heat exchange plates 11 are installed on the outer side of the recovery pipe 9 and the bend 10.

[0024] Two L-shaped connecting frames 3 are each provided with a rotating rod 16 on the outside. Support blocks 17 are rotatably connected to both ends of the rotating rod 16. Both support blocks 17 are fixedly connected to the L-shaped connecting frame 3. One of the rotating rods 16 is provided with an operating structure on the outside. A transmission component is provided between the two rotating rods 16. Two second bevel gears 15 are fixedly connected to the outside of the rotating rod 16. A first bevel gear 13 is meshed with the outside of the two second bevel gears 15. A threaded rod 14 is fixedly connected to one side of the first bevel gear 13. A convex block 12 is threadedly connected to the outside of the threaded rod 14. The convex block 12 is fixedly connected to the bottom of the bracket 4. Two convex grooves 300 are opened at the bottom inside the L-shaped connecting frame 3. The threaded rod 14 passes through the outside of the L-shaped connecting frame 3 and extends into the inside of the convex groove 300. The threaded rod 14 is rotatably connected to the L-shaped connecting frame 3. The convex block 12 is set in the inside of the convex groove 300 and is slidably connected to the L-shaped connecting frame 3.

[0025] The operating structure includes a worm gear 19, which is fixedly connected to the outside of one of the rotating rods 16. A worm 20 is meshed with the outside of the worm gear 19. An L-shaped block is rotatably connected to the outside of the worm 20. The L-shaped block is fixedly connected to the outside of the L-shaped connecting frame 3. A throttle is installed at one end of the worm 20.

[0026] The transmission component includes two sprockets 18, which are fixedly connected to one end of two rotating rods 16 respectively, and the two sprockets 18 are connected by a chain drive.

[0027] Specifically, since multiple recycling pipes 9 are grouped in pairs, if multiple groups of recycling pipes 9 are used, the arc-shaped pipes 8 on the multiple groups of recycling pipes 9 are placed in the corresponding arc-shaped grooves 301 respectively, and the limiting blocks 80 on the arc-shaped pipes 8 are inserted into the corresponding limiting grooves 302, so that the bends 10 on the multiple groups of recycling pipes 9 can be supported and limited, so that the bends 10 on the multiple groups of recycling pipes 9 are placed inside the wastewater pool 1.

[0028] Afterwards, the operator turns the throttle, and the worm gear 20 meshes with the worm wheel 19. The worm wheel 19 drives one of the sprockets 18 to rotate through one of the rotating rods 16. One of the sprockets 18 is connected to the other sprocket 18 by a chain drive, thereby enabling the two rotating rods 16 to rotate. The two second bevel gears 15 set on the two rotating rods 16 also rotate. The four second bevel gears 15 mesh with the four first bevel gears 13, which in turn drive the four threaded rods 14 to rotate. Since the threads of two of the threaded rods 14 are opposite to those of the other two threaded rods 14, the four threaded rods 14 are threadedly connected to the four convex blocks 12, thereby enabling the two brackets 4 to move the water supply pipes 5 and the return pipes 6 in opposite directions. The connecting pipe 7 is inserted into the arc-shaped pipe 8. The connection between the connecting pipe 7 and the arc-shaped pipe 8 is sealed by a sealing gasket. Therefore, multiple arc-shaped pipes 8 can be quickly connected to the water supply pipes 5 and the return pipes 6 respectively.

[0029] In addition, if there is no arc-shaped pipe 8 connected to other connecting pipes 7, the connecting pipe 7 can be closed by using valve 70.
