Description

Technical Field

[0001] This application relates to the field of sludge treatment technology, specifically a sludge treatment pond. Background Art

[0002] Sludge treatment tanks are a key component of wastewater treatment systems, specifically designed to treat coagulated sediments in wastewater. They effectively separate solid particles and biological sludge from wastewater, thereby reducing sludge volume, lowering disposal costs, and mitigating environmental pollution risks.

[0003] A search revealed, for example, a patent with publication number CN217511237U, which specifically discloses a sludge settling tank for sludge treatment. This settling tank separates sludge and wastewater through static settling and discharges the wastewater through a drain pipe below.

[0004] In the sludge treatment process, most drainage pipes are located on the side of the bottom of the tank, which makes them easy to be blocked by sludge. Furthermore, when discharging sewage, it can only be discharged from the bottom. This method still causes the sewage to flow through the sludge before entering the drainage pipe, which makes it easy for sludge to be carried away during the discharge process. This affects the efficiency of separating sewage and sludge, and thus affects the effect of the treatment tank on sludge sedimentation and separation. Therefore, it is necessary to provide a sludge treatment tank to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a sludge treatment tank that avoids the sewage flowing through sludge during sewage discharge, prevents sludge from being carried along during the discharge process, and improves the efficiency of sewage-sludge separation.

[0007] The technical solution adopted by this application to solve its technical problem is: a sludge treatment tank, comprising:

[0008] Support frame;

[0009] A treatment box, which is disposed inside the support frame, is used for sedimentation and separation of sludge;

[0010] A drainage mechanism is provided at the upper end of the treatment box. The drainage mechanism has a fixed pipe frame installed on the support frame. One end of the fixed pipe frame is located above the treatment box. A sewage pipe is provided inside the fixed pipe frame. One end of the sewage pipe is located at the upper end of the treatment box.

[0011] A plastic valve is installed at one end of the sewage pipe located above the treatment tank, and the plastic valve has a water inlet.

[0012] Furthermore, a telescopic pipe is fixedly installed at one end of the sewage pipe near the top of the treatment box, and the water inlet is connected to the telescopic pipe.

[0013] Furthermore, a control mechanism is provided on one side of the sewage pipe. The control mechanism has a fixed plate fixedly installed on the fixed pipe frame. A winding wheel is fixedly installed at the lower end of the fixed plate. The winding wheel is located on one side of the telescopic pipe. A drive motor is fixedly installed on one side of the winding wheel.

[0014] Furthermore, a floating rope is wound on the winding reel, and a float plate is fixedly installed at the other end of the floating rope. The float plate is fixedly connected to the plastic valve.

[0015] Furthermore, a bottom trough is fixedly installed at the lower end of the processing box, and a drain valve is connected to one side of the bottom trough via a pipe. The bottom trough is configured as an inclined channel, and the drain valve is located at the lowest end of the bottom trough.

[0016] Furthermore, a protective shell is fixedly installed on the outside of the support frame, and the protective shell is higher than the height of the processing box.

[0017] The beneficial effects of this application are as follows: The sludge treatment tank provided by this application is equipped with a drainage mechanism. When treating sludge, the drive motor is started to unwind the floating rope until the float plate floats on the surface of the sewage. Then, the water pump is started to suck the sewage into the inlet and discharge it through the sewage pipe. Finally, the sewage valve is opened to discharge the sludge. This avoids the sewage flowing through the sludge when discharging sewage, prevents sludge from being carried away during the discharge process, improves the efficiency of sewage-sludge separation, and ensures the effect of sludge sedimentation and separation in the treatment tank.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] like Figures 1-2 As shown, this application provides a sludge treatment tank, including a support frame 1. The support frame 1 has a treatment tank 2 for treating sludge inside. The treatment tank 2 is used for sedimentation and separation of sludge. A bottom trough 21 is fixedly installed at the lower end of the treatment tank 2 to facilitate the accumulation of sludge at the bottom. At the same time, a drain valve 22 is connected to a pipe on one side of the bottom trough 21. In this application, the bottom trough 21 is set as an inclined channel. The drain valve 22 is located at the lowest end of the bottom trough 21, so it is convenient to discharge the sludge accumulated in the bottom trough 21 to the outside.

[0031] Furthermore, a protective shell 11 is fixedly installed on the outside of the support frame 1. The protective shell 11 is higher than the height of the processing box 2, so the processing box 2 is protected by the protective shell 11.

[0032] like Figures 2-3As shown, in order to discharge the wastewater separated by sedimentation, a drainage mechanism 3 is provided at the upper end of the treatment tank 2. The drainage mechanism 3 has a fixed pipe frame 31 fixedly installed on the support frame 1. One end of the fixed pipe frame 31 is located above the treatment tank 2, and a sewage pipe 32 is provided inside the fixed pipe frame 31. One end of the sewage pipe 32 is located at the upper end of the treatment tank 2, and the other end is connected to a water pipe (not shown). A water pump is connected to the water pipe, and the sewage in the sewage pipe 32 is pumped out and discharged to the required location by the water pump.

[0033] Meanwhile, a telescopic pipe 33 is fixedly installed at one end of the sewage pipe 32 near the top of the treatment box 2, and a plastic valve 34 is fixedly installed at the other end of the telescopic pipe 33. The plastic valve 34 has a water inlet 35, which is connected to the telescopic pipe 33. Therefore, the plastic valve 34 is placed in the sewage, and then the water pump is started to draw the sewage into the sewage pipe 32 and discharge it.

[0034] To prevent the sludge from being extracted, a control mechanism 4 is provided on one side of the sewage pipe 32. The control mechanism 4 has a fixed plate 41 fixedly installed on the fixed pipe frame 31. A winding wheel 42 is installed on the lower bearing of the fixed plate 41. The winding wheel 42 is located on one side of the telescopic pipe 33. A drive motor 45 is fixedly installed on one side of the winding wheel 42. The drive motor 45 is used to drive the winding wheel 42 to rotate. A floating rope 43 is wound on the winding wheel 42. A float plate 44 is fixedly installed at the other end of the floating rope 43. The float plate 44 is fixedly connected to the plastic valve 34.

[0035] In this application, when the float plate 44 floats on the surface of the sewage, the weight of the plastic valve 34 will not pull the float plate 44 into the water, so it will not affect the water intake of the inlet 35.

[0036] In summary: When treating sludge, after pouring the sludge into the treatment tank 2, wait for a period of time for the sludge to settle and separate. After the sludge has settled and separated, start the drive motor 45 to make the winding wheel 42 rotate and unwind the floating rope 43. At this time, the plastic valve 34 and the float plate 44 will pull the floating rope 43 downward with gravity.

[0037] At the same time, the telescopic tube 33 will be stretched until the float plate 44 reaches the surface of the sewage. At this time, due to the effect of buoyancy, the float plate 44 will float on the surface of the sewage, the plastic valve 34 will be in the water, and the sewage separated by sedimentation is clearer above, so it is slowly drawn down from the upper surface of the separated sewage through the float plate 44.

[0038] Then continue to unwind the floating rope 43 until it reaches its longest position. The unwound floating rope 43 will float on the water surface and will not sink to the bottom. At this time, start the water pump to suck the sewage into the telescopic pipe 33 through the inlet 35 and discharge it out through the sewage pipe 32. During this process, the staff observes from the side. When the turbidity of the discharged water increases, stop the drainage and let the sludge continue to settle and separate in the treatment tank 2. After separation, repeat the above operation until the water level is discharged to near the surface of the sludge.

[0039] It should be noted that, in order to avoid pumping out the sludge at the same time during drainage, drainage should be stopped when the drainage reaches close to the surface of the sludge. At this time, the remaining sewage above the sludge is also highly turbid and has little impact on the viscosity of the sludge, so it does not need to be pumped out and can be discharged along with the sludge later.

[0040] After discharge, start the drive motor 45 to rotate the winding wheel 42 to retract the plastic valve 34 and the float 44 for easy reuse next time. Finally, open the drain valve 22 to discharge the sludge, thus avoiding the sewage flowing through the sludge during discharge, preventing sludge from being carried along during discharge, improving the efficiency of sewage-sludge separation, and ensuring the treatment tank's effect on sludge sedimentation and separation.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
