Description

Technical Field

[0001] The present application relates to the field of wastewater treatment, and in particular to a wastewater backflow prevention component and a wastewater treatment sedimentation tank. Background Art

[0002] A sedimentation tank is a structure that uses sedimentation to remove suspended matter in water. It is a water purification equipment that uses the natural sedimentation or coagulation sedimentation of water to remove suspended matter in water. The sedimentation effect is determined by the flow rate of water in the sedimentation tank and the residence time of water in the tank.

[0003] During the use of the wastewater sedimentation tank, sewage flows in the sedimentation tank, so that suspended matter will settle downward. However, the sewage in the existing sedimentation tank flows from the water inlet to the water outlet, making the sewage flow in a straight line as a whole. As a result, there is a situation where the sewage flows through the sedimentation tank for a short time, so it is necessary to increase the overall length of the sedimentation tank. For this reason, we propose a wastewater backflow prevention component and a wastewater treatment sedimentation tank. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0023] See also Figure 1-5 The present application provides a wastewater treatment sedimentation tank, including a tank body 10, the bottom of the tank body 10 is connected to a sewage discharge mechanism 20, and a detachable top plate 30 is installed on the top of the tank body 10, a first crossbeam 40 and a second crossbeam 80 are installed on the inner wall of the tank body 10, and a plurality of wavy plates 50 arranged at equal intervals are detachably connected to the first crossbeam 40 and the second crossbeam 80. Specifically, the top plate 30 is installed on the top of the tank body 10 through the existing screw hole. Specifically, a threaded hole is opened on the top of the tank body 10, and a threaded hole is opened on the top plate 30. The hole corresponds to the mounting hole, and then the screw is passed through the mounting hole and connected to the threaded hole to realize the installation of the top plate 30. The sewage enters the pool body 10, and the water level gradually rises. A drain pipe 60 is connected to the side wall of one end of the pool body 10. The water level rises to the drain pipe 60 and is discharged from the drain pipe 60. The other end of the side wall of the pool body 10 is connected to a water inlet component 70. The sewage flows into the pool body 10 through the water inlet component 70, so that the sewage flows at the top of the pool body 10 and flows through several corrugated plates 50 at the same time, so that the suspended matter is settled to the bottom of the pool body 10.

[0024] See Figure 3 The water inlet assembly 70 includes a U-shaped plate 710 fixedly mounted on the inner wall of the pool body 10. A water inlet pipe 720 is connected to the side wall of one end of the U-shaped plate 710, and a plurality of water outlets 730 are opened on the side wall of the other end. The water inlet pipe 720 is set through the side wall of the pool body 10. When set, the sewage flows into the U-shaped plate 710 through the water inlet pipe 720, and then is discharged into the pool body 10 from the plurality of water outlets 730 to achieve the purpose of diversion, so that the sewage flows through the plurality of wave-shaped plates 50.

[0025] See Figure 3 and 5The first crossbeam 40 is arranged close to the drain pipe 60, and a limiting block 410 is fixedly installed on the top thereof. One end of several corrugated plates 50 rests on the limiting block 410. The second crossbeam 80 is arranged close to the U-shaped plate 710, and a plurality of U-shaped limiting plates 810 are fixedly installed on the top thereof. One end of several corrugated plates 50 is respectively inserted into several U-shaped limiting plates 810. In the specific setting, the limiting block 410 realizes the limitation of the corrugated plates 50. Several corrugated plates 50 will be affected by the impact of the water flow, so that one end of the corrugated plates 50 rests on the limiting block 410. At the same time, the U-shaped limiting plate 810 realizes the clamping of the corrugated plates 50, so that the corrugated plates 50 are set vertically. Furthermore, the corrugated plates 50 are stainless steel plates.

[0026] See Figure 3 and 4 The sewage discharge mechanism 20 includes a plurality of funnels 210, and the plurality of funnels 210 are connected to the bottom of the pool body 10, and the bottoms of the plurality of funnels 210 are connected to a sewage pipe 220, the side wall of the sewage pipe 220 is opened, and a motor 230 is installed on the side wall of the other end, and a screw push rod 240 connected to the drive shaft of the motor 230 is provided in the sewage pipe 220, and a nut 250 is threadedly provided on the opening of the plurality of sewage pipes 220. It is clear that the suspended matter settles into the funnel 210 at the bottom, and when cleaning the bottom sediment, the sewage can be stopped from being transported into the pool body 10, and the motor 230 can be started to drive the screw push rod 240 to rotate, so that the screw push rod 240 can push the sediment to move and then discharge it from the sewage pipe 220. Furthermore, an external thread is opened on the sewage pipe 220, and the external thread is adapted to the nut 250 to seal the opening at one end of the sewage pipe 220.

[0027] A wastewater backflow prevention component, comprising

[0028] The above-mentioned wastewater treatment sedimentation tank can further be provided with a valve on the water inlet pipe 720. After the valve is closed, the sewage in the tank body 10 can be prevented from flowing back.

[0029] When the wastewater backflow prevention component and the wastewater treatment sedimentation tank are in operation: the sewage is transported to the water inlet pipe 720 through the existing sewage conveying device, and then transported to the U-shaped plate 710 through the water inlet pipe 720, so that several water outlets 730 are discharged into the tank body 10, thereby gradually raising the water body in the tank body 10, so that the water level rises to the drain pipe 60, and then the sewage is discharged from the drain pipe 60 to the next process. At this time, the sewage enters the tank body 10 through the water outlet 730, and a sewage sedimentation area is formed on the top of the tank body 10, so that the suspended matter is settled in the funnel 210 at the bottom of the tank body 10, and the sewage flows in several wave-shaped plates 50, which can increase the time for the sewage to flow through the tank body 10 and improve the sedimentation effect.

[0030] Furthermore, when cleaning the sediment at the bottom of the pool body 10 , the motor 230 can be used to drive the screw push rod 240 to rotate, so as to discharge the sediment in the funnel 210 .

[0031] It should be noted that the specific model and specifications of the motor 230 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0032] The power supply and principle of the motor 230 are clear to those skilled in the art and will not be described in detail here.

Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
