Description

Technical Field

[0001] This utility model relates to the field of wastewater technology, and in particular to a wastewater and sludge separation, treatment, and recycling device. Background Technology

[0002] Wastewater refers to wastewater discharged from domestic and industrial processes that has been polluted to some extent. Water that has lost its original function is simply called wastewater, mainly water used for domestic purposes. It contains a relatively high amount of organic matter and is relatively easy to treat. Sludge is the sediment discharged from wastewater treatment facilities. Sediment with organic matter as its main component is called sludge, which is prone to putrefaction and odor.

[0003] However, in existing technologies, during the filtration of sewage sludge, the filtered sludge and impurities accumulate on top of the filter element, which affects the filtration effect and reduces efficiency, thus hindering practical applications. To address these issues, we have developed a sewage sludge separation, treatment, and recycling device. Utility Model Content

[0004] This utility model discloses a sewage sludge separation, treatment, and recycling device, which aims to solve the technical problem that during the filtration process of sewage sludge, the filtered sludge and impurities accumulate on top of the filter element, thereby affecting the filtration effect and reducing efficiency, which is detrimental to practical applications.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A sewage sludge separation, treatment, and recycling device includes a separation tank and a cover plate. First connecting rods are fixedly connected at equal intervals along the inner wall of the cover plate. A fixing block is fixedly connected between multiple first connecting rods. A rotating shaft is rotatably connected to the bottom of each fixing block. Filter plates are rotatably connected at equal intervals along the outer side of the rotating shaft. Second connecting rods are fixedly connected between multiple filter plates. A base plate is rotatably connected to the outer side of the rotating shaft and to the bottom of each filter plate. Moving rods are fixedly connected to both sides of the rotating shaft and to the inside of each filter plate. Actuating teeth are fixedly connected to the bottom of each moving rod.

[0007] By rotating the shaft, the moving rod moves and drives the agitator to scrape and agitate the sewage and sludge on the surface of the filter plate. This prevents the accumulation of mud and debris during filtration from causing blockages. At the same time, the filtration efficiency of the multiple filter plates gradually increases from top to bottom, resulting in a cleaner filtration effect.

[0008] In a preferred embodiment, both sides of the separating tank are slidably connected with snap-fit ​​blocks, and one end of each snap-fit ​​block is fixedly connected with a sliding plate. Both sides of the separating tank, located on both sides of the snap-fit ​​blocks, are fixedly connected with sliding rods, which are slidably connected to the sliding plates. One side of each sliding rod is fixedly connected with a limit block, and a spring is fixedly connected between the limit block and the sliding plate, located on the outside of the sliding rod. One of the filter plates has two snap-fit ​​holes on its outer side, and each snap-fit ​​block is used in conjunction with the corresponding snap-fit ​​holes.

[0009] By means of the spring's elasticity, the sliding plate can be moved, which in turn moves the locking block. The locking block then engages with the locking hole, thus limiting its movement and preventing the filter plate from rotating with the shaft.

[0010] In a preferred embodiment, a servo motor is fixedly connected to the bottom of the separation tank. The output shaft of the servo motor extends into the interior of the separation tank and is fixedly connected to a square rod. A square groove is provided at the bottom of the rotating shaft, and the square rod is used in conjunction with the square groove.

[0011] By inserting a square rod into a square slot, the servo motor can drive the shaft to rotate.

[0012] In a preferred embodiment, a protective cover is fixedly connected to the bottom of the separator tank and outside the servo motor, and water outlet holes are equidistantly opened at the bottom of the separator tank and outside the protective cover.

[0013] The system is designed to allow filtered water to be discharged easily through the water outlet, while the protective cover protects the servo motor.

[0014] In a preferred embodiment, a support ring is fixedly connected to the outside of the separation tank, and support columns are fixedly connected at equal intervals to the bottom of the support ring. A water collection hood is fixedly connected between the multiple support columns and below the water outlet, and a discharge pipe is fixedly connected to the outside of the water collection hood.

[0015] By setting up a support column, the separation tank can be supported, while the water collection hood can collect the separated water and transport it to the next process through the discharge pipe.

[0016] In a preferred embodiment, a discharge hood is fixedly connected to the top of the cover plate and to the outside of the fixing block, and flanges are fixedly connected to both the cover plate and the outside of the separation tank.

[0017] The flange allows for easy connection of the cover plate to the separator tank.

[0018] The wastewater and sludge separation, treatment, and recycling device provided by this utility model has the following advantages:

[0019] Firstly, by rotating the shaft, the moving rod is moved during the rotation, which in turn moves the agitator to scrape and agitate the sewage and sludge on the surface of the filter plate. This prevents the accumulation of mud and debris during the filtration process from causing blockage. At the same time, the filtration degree of multiple filter plates gradually increases from top to bottom, thereby achieving a cleaner filtration effect.

[0020] Secondly, the spring's elasticity allows the sliding plate to move, which in turn moves the locking block. The locking block then engages with the locking hole, limiting its position and preventing the filter plate from rotating with the shaft. By inserting the square rod into the square slot, the servo motor drives the shaft to rotate. Supported by the support column, the separation tank is supported. Meanwhile, the water collection hood collects the separated water and transports it to the next process through the discharge pipe. The flange facilitates the connection between the cover plate and the separation tank. Attached Figure Description

[0027] The wastewater and sludge separation, treatment, and recycling device disclosed in this utility model is mainly used in scenarios where, during the filtration of wastewater and sludge, the filtered sludge and impurities accumulate on top of the filter element, thereby affecting the filtration effect and reducing efficiency, which is detrimental to practical applications.

[0028] Reference Figure 1 and Figure 2 A sewage sludge separation, treatment, and recycling device includes a separation tank 1 and a cover plate 2. First connecting rods 3 are fixedly connected at equal intervals to the inner wall of the cover plate 2. Fixed blocks 4 are fixedly connected between multiple first connecting rods 3. A rotating shaft 5 is rotatably connected to the bottom of the fixed blocks 4. Filter plates 7 are rotatably connected at equal intervals to the outer side of the rotating shaft 5.

Moving rods 9 are fixedly connected to both sides of the rotating shaft 5 and the inside of the filter plates 7. A moving tooth 10 is fixedly connected to the bottom of each moving rod 9.

[0029] In this embodiment, by rotating the rotating shaft 5, the rotating shaft 5 drives the moving rod 9 to move, which in turn drives the agitator 10 to scrape and stir the sewage and sludge on the surface of the filter plate 7. This prevents the accumulation of mud and debris during the filtration process from causing blockage. At the same time, the filtration degree of the multiple filter plates 7 gradually increases from top to bottom, thereby achieving a cleaner filtration effect.

[0030] Reference Figure 1 and Figure 4 In a preferred embodiment, locking blocks 11 are slidably connected to both sides of the separation tank 1, and a sliding plate 12 is fixedly connected to one end of each locking block 11. Sliding rods 13 are fixedly connected to both sides of the separation tank 1 and to both sides of the locking blocks 11. The sliding rods 13 are slidably connected to the sliding plates 12. A limiting block 14 is fixedly connected to one side of each sliding rod 13. A spring 15 is fixedly connected between the limiting block 14 and the sliding plate 12 and to the outside of the sliding rod 13. Two locking holes 16 are opened on the outside of one of the filter plates 7, and the locking blocks 11 are used in conjunction with the corresponding locking holes 16.

[0031] In this embodiment, the elasticity of the spring 15 enables the sliding plate 12 to move, which in turn enables the locking block 11 to move, thereby locking the locking block 11 into the locking hole 16 and limiting its position to prevent the filter plate 7 from rotating with the rotating shaft 5.

[0032] Reference Figure 1 and Figure 3 In a preferred embodiment, a servo motor 19 is fixedly connected to the bottom of the separation tank 1. The output shaft of the servo motor 19 extends into the interior of the separation tank 1 and is fixedly connected to a square rod 20. A square groove 21 is provided at the bottom of the rotating shaft 5. The square rod 20 and the square groove 21 are used in conjunction.

[0033] In this embodiment, by inserting the square rod 20 into the square slot 21, the servo motor 19 can drive the rotating shaft 5 to rotate.

[0034] Reference Figure 1 and Figure 2 In a preferred embodiment, a protective cover 18 is fixedly connected to the bottom of the separator tank 1 and outside the servo motor 19, and water outlet holes 17 are equidistantly provided at the bottom of the separator tank 1 and outside the protective cover 18.

[0035] In this embodiment, the filtered water can be discharged through the water outlet 17, while the protective cover 18 can protect the servo motor 19.

[0036] Reference Figure 1 and Figure 3 In a preferred embodiment, a support ring 22 is fixedly connected to the outside of the separation tank 1, and support columns 23 are fixedly connected at equal intervals to the bottom of the support ring 22. A water collection cover 24 is fixedly connected between the multiple support columns 23 and below the water outlet 17, and a discharge pipe 25 is fixedly connected to the outside of the water collection cover 24.

[0037] In this embodiment, the separation tank 1 can be supported by the support column 23, while the water collection hood 24 can collect the separated water and transport it to the next process through the discharge pipe 25.

[0038] Reference Figure 1 and Figure 4 In a preferred embodiment, a discharge hood 26 is fixedly connected to the top of the cover plate 2 and to the outside of the fixing block 4, and flanges 27 are fixedly connected to both the cover plate 2 and the outside of the separation tank 1.

[0039] In this embodiment, flange 27 facilitates the connection between cover plate 2 and separation tank 1.

[0040] Working principle: When in use, by rotating the rotating shaft 5, the rotating shaft 5 drives the moving rod 9 to move, which in turn drives the agitator 10 to scrape and stir the sewage and sludge on the surface of the filter plate 7. This prevents the accumulation of mud and sand and debris during the filtration process from causing blockage. At the same time, the filtration degree of multiple filter plates 7 gradually increases from top to bottom, thereby achieving a cleaner filtration effect.

[0041] The spring 15's elasticity allows the sliding plate 12 to move, which in turn moves the locking block 11. The locking block 11 then engages with the locking hole 16, thus limiting its position and preventing the filter plate 7 from rotating with the shaft 5. The square rod 20 is inserted into the square groove 21, which in turn drives the shaft 5 to rotate. The support column 23 supports the separation tank 1, while the water collection hood 24 collects the separated water and transports it to the next process through the discharge pipe 25. The flange 27 facilitates the connection between the cover plate 2 and the separation tank 1.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
