Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically to a device for rapid removal of suspended solids in wastewater treatment. Background Technology

[0002] Wastewater treatment refers to the process of treating wastewater (domestic sewage, industrial wastewater, etc.) through physical, chemical, or biological methods to meet certain water quality standards so that it can be safely discharged into the natural environment or used for irrigation, industrial water use, etc. The purpose of wastewater treatment is to reduce harmful substances in wastewater and protect the environment and human health.

[0003] In existing wastewater treatment, it is often necessary to treat the suspended solids in the wastewater. The common treatment method is to add coagulants to the water to contact the suspended solids, form tiny flocs, and then let them settle in a tank. In this case, the wastewater is stirred by stirring blades. Conventional stirring blades are installed in fixed positions, which results in insufficient contact between the coagulant and the suspended solids in other areas of the tank, affecting the removal of suspended solids.

However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0015] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Appendix Figure 6 The present invention will be further described below.

[0016] A rapid suspended solids removal device for wastewater treatment includes: a sedimentation tank 1, with an inlet 5 on one side and a outlet 6 on the other side; a movable column 10 inside the sedimentation tank 1, with a stirring component on the top surface of the movable column 10; a driving component on one side of the movable column 10, with two reciprocating components on the driving component; the driving component can drive the two reciprocating components to rotate synchronously and alternately drive the stirring component to move in a reciprocating linear motion; a guide component on one side of the movable column 10, allowing the stirring component to move linearly along the guide component; the driving component includes: a fixed frame 9, located on one side of the movable column 10; a first fixing bar 2 and two second fixing bars 3 are fixedly connected inside the sedimentation tank 1; the fixed frame 9 is fixedly connected to the two second fixing bars 3; a first drive motor 11 is fixedly connected to one side of the fixed frame 9; the driving end of the first drive motor 11 passes through the fixed frame 9 and is fixedly connected to a first gear 16; the first gear 16 is connected to the reciprocating components.

[0017] Specifically, the reciprocating component includes: two second gears 15, both of which are rotatably connected to one side of the fixed frame 9. One end of the second gear 15 is fixedly connected to a fixed rod 14, and a sector gear 13 is fixedly connected to the outer wall of the fixed rod 14.

[0018] In this embodiment, the first drive motor 11 is provided. The drive shaft of the first drive motor 11 rotates, which drives the first gear 16 to rotate clockwise. The first gear 16 drives the two second gears 15 to rotate counterclockwise, which in turn drives the sector gears 13 to rotate through the fixed rod 14, so that the two sector gears 13 rotate synchronously.

[0019] Specifically, the drive component also includes two racks 12, which are fixed to the top and bottom surfaces of the moving column 10 respectively, and the racks 12 are meshed with the sector gear 13.

[0020] In this embodiment, when the two sector gears 13 alternately drive the rack 12, the rack 12 will drive the moving column 10 to reciprocate linearly between the first fixed bar 2 and the second fixed bar 3.

[0021] Specifically, the stirring component includes two second drive motors 20, both of which are fixedly connected to the top surface of the moving column 10. The driving end of the second drive motor 20 passes through the moving column 10 and is fixedly connected to a stirring blade 19.

[0022] In this embodiment, the second drive motor 20 is provided. The drive shaft of the second drive motor 20 rotates, which drives the stirring plate 19 to rotate and stir the sewage. During stirring, coagulant is added to the sewage. Through the stirring of the stirring plate 19, the coagulant can come into contact with the suspended solids and form tiny flocs, which facilitates the removal of suspended solids.

[0023] Specifically, the guide component includes two guide grooves 17, both of which are opened on the side of the first fixing strip 2 and the second fixing strip 3 that are close to each other. A guide block 18 is slidably connected inside the guide groove 17, and the guide block 18 is fixedly connected to the moving column 10.

[0024] In this embodiment, the guide block 18 is provided so that when the moving column 10 moves linearly between the first fixed bar 2 and the second fixed bar 3, the moving column 10 can slide inside the guide groove 17 through the guide block 18, thereby playing a guiding role when the moving column 10 moves.

[0025] Specifically, an air pump 8 is fixedly connected to one side of the sedimentation tank 1, and a connecting pipe 7 is fixedly connected to the air outlet pipe of the air pump 8. Several round holes are opened on one side of the sedimentation tank 1, and a one-way air valve 4 is fixedly connected inside the round holes. The one-way air valve 4 is fixedly connected to the connecting pipe 7.

[0026] In this embodiment, an air pump 8 is installed to draw in outside air, which is then injected into the sedimentation tank 1 through a connecting pipe 7 and a one-way air valve 4. When the gas enters the sewage, it forms bubbles. Due to buoyancy, the bubbles move upward in the sewage. During the upward movement, the bubbles drive the surrounding water, generating eddies and stirring effects, which further improves the mixing effect of the coagulant and suspended solids, thereby achieving the effect of rapid removal of suspended solids.

[0027] The working principle and usage process of this utility model are as follows: During use, the operator connects the external inlet pipe to the water inlet 5 and the external outlet pipe to the drain outlet 6. Then, the valve of the external inlet pipe is opened, and the valve of the external outlet pipe is closed. Wastewater is injected into the sedimentation tank 1 through the external inlet pipe. After the wastewater is injected, the drive shaft of the second drive motor 20 rotates, driving the stirring plate 19 to rotate and stir the wastewater. During stirring, coagulant is added to the wastewater. At this time, the drive shaft of the first drive motor 11 rotates, driving the first gear 16 to rotate clockwise. The first gear 16 drives the two second gears 15 to rotate counterclockwise, which in turn drives the sector gear 13 to rotate through the fixed rod 14. The two sector gears 13 alternately drive the rack 12 to reciprocate. The drive rack 12 drives the moving column 10 to reciprocate linearly between the first fixed bar 2 and the second fixed bar 3. The movement of the moving column 10 drives the second drive motor 20 and the stirring plate 19 to reciprocate linearly, further increasing the stirring range and allowing the coagulant to fully contact the suspended solids, forming tiny flocs that settle faster. Then, the air pump 8 draws in outside air and injects it into the sedimentation tank 1 through the connecting pipe 7 and the one-way air valve 4. The gas entering the sewage forms bubbles. Due to buoyancy, the bubbles move upward in the sewage. During the upward movement, the bubbles drive the surrounding water, generating eddies and stirring effects, further improving the mixing effect of the coagulant and suspended solids, and achieving the effect of rapid removal of suspended solids.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
