[0002] With the acceleration of urbanization and the surge in sewage treatment volume, the output of sludge, a byproduct of sewage treatment, is increasing year by year. Sludge has a high water content, and if it is not effectively dewatered, it is prone to bacterial growth and the release of harmful substances, posing a potential pollution to the soil, water bodies, and other ecological environments. Therefore, sludge dewatering has become a core step in sludge reduction and harmless treatment. Sludge dewatering requires related dewatering devices. Currently, most equipment on the market can only achieve the basic goal of "reducing moisture content" after sludge dewatering. The output state is generally loose flocculent, granular, or semi-fluid, and it does not have the ability to form stable shapes, which brings many practical problems to subsequent transportation and transfer.

[0016] The sludge dewatering device for sludge treatment of this utility model will be described in more detail below with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of this utility model. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this utility model.

[0017] Furthermore, based on the teachings of this specification, those skilled in the art can form new technical solutions through cross-combination of different implementation methods without creating technical contradictions. Such variations should all be considered to fall within the protection scope of this patent.

[0018] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0019] like Figure 1 As shown in the figure, this utility model embodiment proposes a sludge dewatering device for sludge treatment, including a screw dewatering mechanism 1, a buffer chamber 2, and an extrusion shaping mechanism 3; Specifically, the buffer chamber 2 is installed on the discharge port of the screw dewatering mechanism 1, and a control valve 20 is installed at the bottom of the buffer chamber 2; the extrusion shaping mechanism 3 includes a shaping frame 30, a rotating seat 31, a base 32, and a pressure plate 33; the shaping frame 30 is located below the control valve 20, and there are two shaping frames 30, which are symmetrically installed on the rotating seat 31; the pressure plate 33 is located on one side of the buffer chamber 2, and the pressure plate 33 is installed on the base 32 by a lifting cylinder 34 that controls its lifting and lowering, and the distance between the center of the pressure plate 33 and the center of the control valve 20 is the same as the distance between the centers of the two shaping frames 30; the center of the rotating seat 31 is rotatably installed on the base 32 by a rotating shaft 35, and the rotating shaft 35 is connected to a switching motor 36.

[0020] In this embodiment, the screw dewatering mechanism 1 is a high-efficiency device that achieves solid-liquid separation through mechanical extrusion. The core principle is to use the rotation of the screw shaft to propel the material forward, while simultaneously forming a pressure gradient through the variable diameter screw pitch, filter gap structure and back pressure device, forcing water to be discharged from the material.

[0021] When dewatering sludge, the screw dewatering mechanism 1 is started first and the sludge is continuously fed into the screw dewatering mechanism 1. Under the action of the screw dewatering mechanism 1, the dewatered sludge is discharged from the screw dewatering mechanism 1, thus realizing the dewatering of sludge.

[0022] After dewatering, the sludge is first buffered in the buffer chamber 2. Then, the control valve 20 is opened, and the sludge buffered in the buffer chamber 2 is discharged into the shaping frame 30 directly below it. After the shaping frame 30 contains a certain amount of sludge, the control valve 20 is closed. Then, the switching motor 36 is started to switch another shaping frame 30 to the position directly below the control valve 20. The shaping frame 30 containing sludge moves to the position directly below the pressure plate 33. Then, the control valve 20 is opened again, and the lifting cylinder 34 is simultaneously activated to extend and retract, completing the shaping of the dewatered sludge.

[0023] In the above implementation process, during the switching of the shaping frame 30 station, the control valve 20 is in the closed state. The material output of the screw dewatering mechanism 1 can be buffered through the buffer chamber 2, which means that the dewatering operation does not need to be paused during the shaping process, thus ensuring the continuity of the entire process.

[0024] In summary, the sludge dewatering device for sludge treatment provided in this embodiment can realize the dewatering and shaping of sludge, which facilitates the subsequent transportation of sludge. Moreover, the dewatering operation does not need to be interrupted during the sludge shaping process, ensuring the continuity of the overall process and having better work efficiency.

[0025] In a preferred embodiment, the sidewall of the shaping frame 30 is provided with a plurality of drainage holes 300.

[0026] With the drainage hole 300, a small amount of water in the sludge can be discharged from the shaping frame 30 through the drainage hole 300 during the pressing and shaping process of the pressure plate 33. This achieves secondary dewatering of the sludge and improves the dewatering effect of the sludge.

[0027] In the above embodiments, in conjunction with reference to Figure 2 The bottom surface of the shaping frame 30 is provided with a plurality of positioning holes 301, and the rotating seat 31 has positioning posts 310 that match the positioning holes 301.

[0028] The positioning hole 301 and positioning post 310 enable the disassembly, positioning and installation of the shaping frame 30 and the rotating seat 31. This facilitates the replacement of different shaping frame types 30 according to actual conditions, and also facilitates the individual maintenance of the shaping frame 30 and the removal of mud cake from the shaping frame 30.

[0029] Furthermore, the end of the positioning post 310 and the end face of the positioning hole 301 are respectively provided with attractive magnets (not shown in the figure). By setting the magnets, the ease of disassembly of the shaping frame 30 is ensured, while the stability of the shaping frame 30 is ensured during installation.

[0030] In the above embodiments, optionally, the switching motor 36 is a geared motor. A geared motor is a drive device that integrates a motor and a reduction mechanism. Its core function is to reduce the output speed of the motor and amplify the torque through the reduction mechanism to meet the needs of mechanical equipment for low-speed, high-torque power.

[0031] In the above embodiment, the buffer chamber 2 is detachably installed on the discharge port of the screw dewatering mechanism 1 using a flange 21.

[0032] The flange 21, in conjunction with the bolts, allows the buffer chamber 2 to be stably installed on the screw dehydration mechanism 1, while ensuring the removability of the buffer chamber 2 to facilitate maintenance and cleaning of the interior of the buffer chamber 2.

[0033] In an optional embodiment, the lifting cylinder 34 is mounted on the base 32 via a support frame (not shown in the figure), and a plurality of telescopic rods 37 are connected between the support frame and the pressure plate 33, with the plurality of telescopic rods 37 spaced apart from the lifting cylinder 34.

[0034] Specifically, refer to Figure 3 The telescopic rod 37 includes an outer cylinder 370 and an inner rod 371; the outer cylinder 370 and the inner rod 371 are respectively connected to the support frame and the pressure plate 33, and the inner rod 371 is slidably installed in the outer cylinder 370.

[0035] The stability of the pressure plate 33 is improved by setting the telescopic rod 37, thereby ensuring a good shaping effect.

[0036] In summary, compared with the prior art, this utility model has at least the following advantages: The sludge dewatering device for sludge treatment provided by this utility model can realize the shaping operation after sludge dewatering, which facilitates subsequent transportation. Moreover, the dewatering operation does not need to be interrupted during the sludge shaping process, ensuring the continuity of the overall process and having better work efficiency. Furthermore, the side wall of the shaping frame in the extrusion shaping mechanism is provided with drainage holes, which enables secondary dewatering of sludge to a certain extent during the shaping process, thereby improving the dewatering effect of sludge.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
