Description

Technical Field

[0001] The utility model relates to the field of water surface pollutant treatment, in particular to a water surface sewage discharge device. Background Art

[0002] In the garbage leachate treatment equipment, the regulating tank is a place where the activated sludge is fully exposed to microorganisms and provided with oxygen. Generally, a small amount of foam will be generated during the aeration process. These foams are fragile and non-sticky. When the organic components in the leachate change, the load will increase, the temperature will decrease, the pH value will decrease, and the dissolved oxygen level will decrease, which will easily breed filamentous bacteria. When the filamentous bacteria are dominant, a large amount of foam will appear and it will not be fragile, which will prevent normal aeration and oxygenation, reduce the dissolved oxygen of the mixed liquid, and affect the stable operation of the treatment equipment. In severe cases, it will cause the entire leachate system to be paralyzed. In the prior art, when a large number of bubbles are generated in the regulating tank, the amount of defoaming agent input will be increased or the system load will be reduced to reduce the amount of bubbles. No matter which method is used, the treatment efficiency of the leachate is affected and the cost investment is increased. Therefore, it is necessary to propose a water surface sewage discharge device for timely treatment of foam or other waste in the regulating tank. Utility Model Content

[0003] In view of the above problems, the main purpose of the utility model is to provide a water surface sewage discharge device, which can promptly collect and treat foam or other solid waste in the regulating tank. Compared with the water surface sewage discharge device in the prior art, the sewage discharge device has higher sewage discharge efficiency and can realize automatic garbage treatment.

[0004] In order to achieve the above-mentioned purpose, the water surface sewage discharge device of the utility model includes an outer water tank, a sewage tank and a positioning device. The sewage tank is arranged in the outer water tank. It also includes a submersible pump and a mud press. The submersible pump is located at the bottom of the outer water tank. A throttle plate is provided at the upper end of the outer water tank. A plurality of water distribution holes are evenly arranged on the throttle plate.

[0033] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] like Figure 1 FIG. 1 is a partial structural diagram of a water surface sewage discharge device of the utility model. The water surface sewage discharge device of the utility model is provided with an outer water tank 10, a sewage tank 20 and a submersible pump 30. Figure 1 As shown, the structure of the outer water tank 10 and the sewage tank 20 is a rectangular parallelepiped structure, and the sewage tank 20 is sleeved in the outer water tank 10. When the surface sewage discharge device is in a static state, the height of the sewage tank 20 is greater than the height of the outer water tank 10, and the submersible pump 30 is located at the bottom of the outer water tank 10. The working principle of the structure is to place the outer water tank 10 with the sewage tank 20 in a regulating tank or other reaction tank. In this embodiment, the submersible pump is selected with a flow rate of 4-6m³ / h, a head of 8-10m, and a voltage of 22v. After starting the submersible pump 30, due to the water pressure difference between the inside and outside of the outer water tank 10, the sewage tank 20 will quickly drop to a height flush with or lower than the outer water tank 10, and the water pressure causes the foam or other sewage around the outer water tank 10 to quickly flow into the sewage tank 20, and under the repeated starting of the submersible pump 30, the sewage around can be collected in the sewage tank 20 as soon as possible.

[0035] See also Figure 1 and Figure 2As shown, a throttle plate 101 is provided at the upper end of the outer water tank 10 of the utility model. In this embodiment, the throttle plate 101 at the upper end of the outer water tank 10 forms a U-shaped structure 103, and the sewage tank 20 is located in the hollow part in the middle of the U-shaped structure 103. The water distribution holes 102 are evenly distributed around the throttle plate 101 of the U-shaped structure 103. The throttle plate 101 is provided with a plurality of water distribution holes 102. This design can make the outer water tank 10 often in an unsaturated state and increase the water flow rate at the same time. Specifically, the sum of the flow rates of the diameters of all the water distribution holes 102 is slightly lower than the flow rate of the submersible pump 30, thereby increasing the flow rate of water around the outer water tank 10, thereby enhancing the foam and sewage collection efficiency.

[0036] In addition, a sewage pipe (not marked in the figure) is also provided at the bottom of the sewage tank 20 of the sewage discharge device in the utility model. Specifically, the sewage discharge device is also provided with a mud press. A connecting hole is provided at the bottom of the outer water tank 10. The outer end of the sewage pipe passes through the connecting hole and is connected to the mud press. The connecting hole is sealed on all sides. A pneumatic pump is provided on the sewage pipe. When the foam or other pollutants collected in the sewage tank 20 are full, or while the sewage in the sewage tank 20 is collected, the pneumatic pump can be turned on at any time to discharge the sewage in the sewage tank 20 through the sewage pipe and into the mud press, so that the sewage tank 20 can be cleaned in time without manually taking out the sewage tank 20 for cleaning. This structure saves labor costs and cleans in time, thereby improving the overall sewage discharge efficiency of the device.

[0037] In other embodiments, the sewage discharge device of the utility model is further provided with a positioning device, such as Figure 3 As shown, it is a usage status diagram of the sewage discharge device of this embodiment. In this embodiment, the positioning device is provided with a positioning frame 401, a support frame 402, a threaded screw 403, a screw sleeve 404 and a hand wheel 405. The positioning frame 401 is fixed on a plane by an expansion screw 406. Specifically, it is fixed on the plane of the regulating tank 50. The support frame 402 is connected to the positioning frame 401. The support frame 402 is provided with an adjustment hole 407. The screw sleeve 404 is located in the adjustment hole 407. The upper end of the threaded screw 403 is axially connected to the hand wheel 405, and the lower end passes through the screw sleeve 404 and is fixedly connected to the outer water tank 10. The threaded screw 403 can pass through the sewage tank 20 and then be fixedly connected to the outer water tank 10, or it can be directly fixedly connected from the outside of the outer water tank 10.

[0038] The outer water tank 10 of the sewage discharge device of the utility model is a rectangular structure in order to be more suitable for fitting with the inner wall of the regulating tank 50. In addition, the positioning device can adjust the height of the outer water tank 10 at any time to adapt to different liquid level height requirements, and the adjustment method is flexible. The specific operating principle is that since the bottom of the threaded screw 403 is connected to the outer water tank 10, the height of the outer water tank 10 can be adjusted by the worker turning the hand wheel 405 to adapt to different water flow heights. In other embodiments, the hand wheel 405 may not be set, and the threaded screw 403 may be set as an automatic turning rod. The worker can start the switch of the automatic turning rod to adjust the liquid level of the outer water tank 10 at any time.

[0039] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
