Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically a wastewater treatment sludge removal machine. Background Technology

[0002] Sludge treatment is a crucial step in wastewater treatment processes, and its volume reduction effect directly impacts subsequent transportation and disposal costs. Wastewater treatment sludge dewatering machines, also known as sludge dewatering machines, are the core equipment for achieving sludge volume reduction. Their main function is to mechanically dewater highly fluid sludge with a moisture content typically between 90% and 99%, forming solid or semi-solid sludge cakes with a moisture content reduced to 60%-85%. This process can significantly reduce sludge volume by 70%-90%, substantially lowering the overall costs of storage, transportation, and final disposal. Therefore, it has wide applications in municipal wastewater and industrial wastewater treatment.

[0003] Currently, most mainstream sludge dewatering equipment uses mechanical extrusion for dewatering. This unidirectional extrusion dewatering method has inherent operational cycle limitations: after one feeding cycle is completed, the entire extrusion stroke must be finished and the water fully discharged before the next sludge feeding can proceed. This intermittent working mode results in a low effective processing capacity per unit time when treating wastewater with low concentration and low sludge content, and the overall dewatering efficiency cannot be fully realized. Especially when the influent sludge concentration fluctuates or is at a low level, the proportion of idle or waiting time increases, which not only leads to a relative increase in energy consumption but also restricts the overall processing capacity and operating economy of the treatment system. Therefore, it is necessary to improve the structure and working mode of existing dewatering machines to enhance their adaptability to operating conditions and processing efficiency. Summary of the Invention

[0004] This invention provides a wastewater treatment sludge removal machine, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A wastewater treatment sludge descaling machine includes a base, a semi-cylindrical receiving tank is provided above the base, a plurality of arc-shaped partition plates are evenly arranged in the semi-cylindrical receiving tank along its axial direction, and a water intake mechanism and an attitude adjustment mechanism are also included.

[0007] An attitude adjustment mechanism, mounted on the base, is used to adjust the height of the semi-cylindrical receiving groove and its tilt angle relative to the horizontal plane.

[0008] The water intake mechanism is located inside a semi-cylindrical receiving tank. It includes a drive shaft that is coaxially arranged with the semi-cylindrical receiving tank and can rotate in a specific direction. A central guide pipe is coaxially sleeved outside the drive shaft. A water collection tank is arranged circumferentially outside the central guide pipe. Semi-elliptical water collectors that are connected to the water collection tank are evenly distributed on the side of the water collection tank away from the central guide pipe. Several water inlet holes are opened on one side arc surface of the semi-elliptical water collector.

[0009] When the central guide pipe rotates directionally with the drive shaft, the side of the semi-elliptical water collector with the water inlet hole first contacts the liquid surface of the semi-cylindrical receiving tank and passes through the gap between two adjacent arc-shaped partition plates.

[0010] As a preferred embodiment of the present invention, the water collection tank has a second chamber inside, and the central guide pipe has a first chamber that communicates with the second chamber. When there are two or more water collection tanks, each water collection tank is symmetrically distributed around the central guide pipe. The central guide pipe has a first chamber that corresponds to each water collection tank and is independent of each other. The end of the central guide pipe is provided with a drainage component for discharging liquid from the first chamber.

[0011] As a preferred embodiment of the present invention, the semi-elliptical water collector has a hollow structure, its inner cavity is connected to the second chamber, and the distance from the top of the semi-elliptical water collector to the center line of the drive shaft is less than the inner wall radius of the semi-cylindrical receiving groove.

[0012] As a preferred embodiment of the present invention, the water intake mechanism further includes a vertical support fixedly disposed on one side of the base, a U-shaped support frame at the top of the vertical support frame, one end of the U-shaped support frame being rotatably connected to the drive shaft, and a rotary drive device for driving the drive shaft to rotate is provided on the U-shaped support frame, and the other end of the U-shaped support frame being rotatably connected to the central guide pipe.

[0013] As a preferred embodiment of the present invention, the drainage assembly includes a drainage connector fixedly installed on the side of the U-shaped support frame. A rotary joint is provided at one end of the drainage connector near the central guide pipe. The rotary joint is connected to the first chamber in the central guide pipe through a water outlet pipe to achieve fluid conduction. A drainage hose is connected at the other end of the drainage connector away from the central guide pipe.

[0014] As a preferred embodiment of the present invention, the arc-shaped partition plate and the semi-cylindrical receiving groove are detachably connected, and multiple arc-shaped partition plates are fixedly installed on the same fixed frame, and a semi-circular groove is provided at the end of the semi-cylindrical receiving groove.

[0015] As a preferred embodiment of the present invention, the attitude adjustment mechanism includes hinged supports respectively disposed at the four corners of the base, each hinged support being hinged to a lifting actuator, the output end of the lifting actuator being hinged to a push rod, and the end of the push rod being connected to the corresponding corner position of the end of the semi-cylindrical receiving groove.

[0016] As a preferred embodiment of the present invention, two support rollers are arranged parallel to each other along the axial direction of the semi-cylindrical receiving groove in the middle of the base, and the two ends of each support roller are rotatably connected to the end of the base through bearing seats.

[0017] The present invention has the following advantages:

[0018] 1. Significantly improved processing efficiency: Traditional squeeze-type dewatering machines operate intermittently, resulting in waiting periods. This invention utilizes a semi-elliptical water collector that rotates continuously within the tank, enabling simultaneous water intake, filtration, and drainage. This allows the equipment to continuously process low-concentration wastewater, significantly increasing the processing capacity per unit time and effectively overcoming the low efficiency problem of traditional equipment under low sludge loads.

[0019] 2. Enhanced dewatering effect: The equipment combines gravity sedimentation and dynamic mechanical extrusion as dual dewatering mechanisms. The arc-shaped partition plate not only promotes rapid settling and stable distribution of sludge, but also restricts the sludge flow space, allowing the rotating semi-elliptical water collector to effectively compress the deposited sludge, further reducing the moisture content of the sludge cake and increasing the overall dewatering depth.

[0020] 3. Simple operation and maintenance: The coordinated design of the attitude adjustment mechanism and the detachable partition plate greatly simplifies the sludge cleaning process. Through simple lifting and tilting operations, combined with overall placement and removal, the semi-elliptical water collector can be quickly cleaned and sludge dumped, significantly reducing equipment downtime and manual labor intensity.

[0021] 4. The structure is reliable and highly adaptable. The cooperation between the support roller and the multi-degree-of-freedom attitude adjustment mechanism reduces the dependence on the control precision of the lifting actuators, allowing the use of conventional power components, enhancing system reliability and reducing costs. The equipment can flexibly adjust the inclination angle and height of the semi-elliptical water collector to adapt to different feeding conditions and site requirements, improving overall working condition adaptability.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] In one embodiment, see Figure 1 ,Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 A wastewater treatment sludge descaling machine includes a base 1, preferably made of welded metal profiles, with an overall rectangular structure, allowing it to be placed directly and stably on the ground. A semi-cylindrical receiving tank 2 is provided above the base 1. This semi-cylindrical receiving tank 2 has a thin-walled structure and extends horizontally along its axis. Multiple arc-shaped partition plates 5 are arranged sequentially along the axial direction inside the semi-cylindrical receiving tank 2. The outer arc surface of each arc-shaped partition plate 5 is tightly fitted to the inner wall of the semi-cylindrical receiving tank 2 and is evenly distributed along the tank's axis. The invention also includes a water intake mechanism 4 and a posture adjustment mechanism 3.

[0035] The attitude adjustment mechanism 3 is mounted on the base 1. It can push the semi-cylindrical receiving tank 2 to move up and down, and can also rotate it back and forth around the horizontal axis to adjust the pitch angle of the receiving tank. The water intake mechanism 4 is located directly above the base 1. When the semi-cylindrical receiving tank 2 rises to the working position, the water intake mechanism 4 can enter the tank. The water intake mechanism 4 includes a drive shaft 15 coaxially arranged with the semi-cylindrical receiving tank 2. The drive shaft 15 can rotate in a specific direction. A central guide pipe 16 is coaxially mounted on the left end of the drive shaft 15. The central guide pipe 16 extends to the left to the outside of the semi-cylindrical receiving tank 2. A water collection tank 17 is provided outside the central guide pipe 16. Both are arranged horizontally and are internally interconnected. A semi-elliptical water collector 18 is provided on the side of the water collection tank 17 away from the central guide pipe 16. The semi-elliptical water collector 18 is perpendicularly connected to the side of the water collection tank 17, and its arc-shaped surface is arranged in the front-back direction. Several water inlet holes 19 are opened on one side of the arc surface of the semi-elliptical water collector 18, and the water inlet holes 19 are connected to the internal cavity of the water collector. In order to facilitate the alignment and installation of the central guide pipe 16 and the drive shaft 15, semi-circular grooves 6 can be opened at both ends of the semi-cylindrical receiving groove 2 to ensure that the axis of the drive shaft 15 and the central guide pipe 16 coincides with the axis of the semi-cylindrical receiving groove 2.

[0036] When the central guide pipe 16 rotates directionally with the drive shaft 15, the semi-elliptical water collector 18 enters the sewage in the semi-cylindrical receiving tank 2 from top to bottom, with the side equipped with the inlet hole 19 contacting the liquid surface first. This allows water in the sewage to enter the interior of the semi-elliptical water collector 18 through the inlet hole 19 and eventually collect in the collection tank 17, thus achieving preliminary separation of sewage and sludge. When the semi-elliptical water collector 18 rotates to the bottom of the semi-cylindrical receiving tank 2, it can pass through the gap between two adjacent arc-shaped partition plates 5. At this time, the sludge deposited at the bottom of the tank is confined between the adjacent partition plates. The continuously rotating semi-elliptical water collector 18 exerts a squeezing effect on the sludge as it passes through the gap, further enhancing the dewatering effect. In addition, the arc-shaped partition plates 5 also play a role in stabilizing the flow and promoting rapid sludge deposition.

[0037] In one instance of this embodiment, please refer to Figure 1 , Figure 7 , Figure 8 and Figure 9 The water collection tank 17 has a second chamber 26 inside, which has a rectangular cross-section. A first chamber 25 communicating with the second chamber 26 is located inside the central guide pipe 16. When there are two or more water collection tanks 17, they are symmetrically distributed around the central guide pipe 16. For example, when two water collection tanks 17 are provided, they are located on the upper and lower sides of the central guide pipe 16, respectively. The central guide pipe 16 has two independent first chambers 25, one above the other, which communicate with the second chambers 26 of the upper and lower water collection tanks 17, but are not interconnected. A drainage assembly 24 is provided at the left end of the central guide pipe 16 to drain the water collected in the first chambers 25.

[0038] The semi-elliptical water collector 18 has a hollow structure, and its bottom communicates with the water collection tank 17, meaning that the inner cavity of the semi-elliptical water collector 18 is connected to the second chamber 26. Wastewater enters the semi-elliptical water collector 18 through the inlet hole 19 and then flows into the water collection tank 17. The distance from the top of the semi-elliptical water collector 18 to the center line of the drive shaft 15 is less than the inner diameter of the semi-cylindrical receiving tank 2, ensuring that it does not interfere with the tank wall during rotation; when it rotates to the bottom and passes through the gap of the arc-shaped partition plate 5, it can squeeze the sludge accumulated in the gap, thereby further improving the dewatering efficiency.

[0039] In one instance of this embodiment, please refer to Figure 2 , Figure 4 and Figure 7 The water intake mechanism 4 also includes a vertical support 13 fixed to the middle of the rear side of the base 1. A U-shaped support frame 14 with an opening facing downwards is mounted on the top of the vertical support 13, spanning above the semi-cylindrical receiving tank 2. The right end of the U-shaped support frame 14 is rotatably connected to the right end of the drive shaft 15. The left side of the drive shaft 15 is covered by a central guide pipe 16, the left end of which is rotatably connected to the left end of the U-shaped support frame 14, thus ensuring that the drive shaft 15 and the central guide pipe 16 remain horizontally stable during rotation. A rotary drive device 27 is provided at the right end of the U-shaped support frame 14. The rotary drive device 27 drives the drive shaft 15 to rotate via belt transmission, thereby causing the central guide pipe 16 and the semi-elliptical water collector 18 to rotate synchronously and directionally.

[0040] In one instance of this embodiment, please refer to Figure 7 , Figure 8 and Figure 9The drainage assembly 24 is installed at the left end of the U-shaped support frame 14. A suspension rod is fixed to the left end of the U-shaped support frame 14, and the suspension rod is connected to the drainage connector 22. A rotary joint 21 is fitted to the right end of the drainage connector 22, and the rotary joint 21 can rotate relative to the drainage connector 22. Several water outlet pipes 20 are connected to the right side of the rotary joint 21, and each water outlet pipe 20 corresponds to and is connected to a corresponding first chamber 25 in the central guide pipe 16. During the rotation of the central guide pipe 16, the water in the first chamber 25 can enter the drainage connector 22 through the water outlet pipes 20 and the rotary joint 21. The left end of the drainage connector 22 is connected to a drainage hose 23, which is connected to the subsequent water treatment equipment, so that the sewage after sludge removal can be continuously transported to the subsequent treatment stage.

[0041] In one instance of this embodiment, please refer to Figure 3 and Figure 6 The arc-shaped partition plate 5 is detachably connected to the semi-cylindrical receiving groove 2. Multiple arc-shaped partition plates 5 are fixed to an integral fixing frame 12, which is welded from an arc-shaped metal plate and a long strip of metal plate. Its shape matches the contour of the inner wall of the semi-cylindrical receiving groove 2. The fixing frame 12 has outward-extending baffles at both ends to prevent interference positioning with the sides of the semi-cylindrical receiving groove 2 during installation, thus preventing the fixing frame 12 and the partition plates from shaking within the groove. During cleaning, the fixing frame 12 and the arc-shaped partition plates 5 can be removed as a whole, restoring the inner wall of the semi-cylindrical receiving groove 2 to a smooth arc surface for easy rinsing and cleaning.

[0042] In one instance of this embodiment, please refer to Figure 3 , Figure 4 and Figure 5 The attitude adjustment mechanism 3 includes hinged supports 7 located at the four corners of the upper surface of the base 1. Each hinged support 7 is hinged to the lower end of a lifting actuator 8, which can be a cylinder, a hydraulic cylinder, or an electric push rod 9. The extended end of the lifting actuator 8 is hinged to the push rod 9, and the end of the push rod 9 is hinged to the corresponding corner portions at both ends of the semi-cylindrical receiving groove 2. By controlling the extension and retraction of each lifting actuator 8, the attitude adjustment of the semi-cylindrical receiving groove 2 can be achieved: if the four corner actuators extend synchronously, the semi-cylindrical receiving groove 2 rises as a whole; if only the two rear actuators extend, the semi-cylindrical receiving groove 2 flips forward, achieving pitch angle adjustment.

[0043] To reduce the precision requirements for the extension and retraction control of the lifting actuators 8, bearing seats 10 are provided at the center of both ends of the base 1. The bearing seats 10 rotatably support horizontally arranged support rollers 11. A support roller 11 is also provided at the front and rear of the base 1. When the four corner lifting actuators 8 are fully retracted, the semi-cylindrical receiving grooves 2 fall onto the support rollers 11. If only the rear lifting actuator 8 extends, the bottom of the semi-cylindrical receiving groove 2 can roll forward along the support rollers 11, achieving a flip. This structure allows the use of ordinary pneumatic or hydraulic cylinders; the action can be completed by controlling the output pressure, reducing equipment manufacturing costs and control complexity.

[0044] In this embodiment, the base 1 is placed stably on the ground, and a sewage discharge port is set above the semi-cylindrical receiving tank 2 to allow sewage to be directly injected into the tank. A drain hose 23 is connected to subsequent treatment equipment, and a fixing frame 12 equipped with an arc-shaped partition plate 5 is placed into the semi-cylindrical receiving tank 2. Four lifting actuators 8 are activated to raise the semi-cylindrical receiving tank 2 to the working position, and the drive shaft 15 and the central guide pipe 16 enter the tank. The rotary drive device 27 is activated to drive the drive shaft 15 and the central guide pipe 16 to rotate in a specific direction. The sewage discharge port is opened, and sewage is slowly injected into the semi-cylindrical receiving tank 2 at a level lower than the bottom edge of the semi-cylindrical tank 6.

[0045] Sludge removal step: The drive shaft 15 drives the central guide pipe 16 to rotate (for example, clockwise when viewed from the left), and the semi-elliptical water collector 18 enters the sewage from top to bottom and from the front. The water inlet 19 on its side comes into contact with the sewage, and the water enters the interior of the semi-elliptical water collector 18 through the hole, realizing the initial separation of sludge and water.

[0046] Drainage Procedure: As the semi-elliptical water collector 18 rotates from bottom to top, the water accumulated inside flows into the collection tank 17. Since there is no inlet hole 19 on the other side of the semi-elliptical water collector 18, the water will not leak out in reverse. As the drive shaft 15 continues to rotate, a small amount of water may flow back from the inlet hole 19, but most of it remains in the collection tank 17. When the collection tank 17 rotates to the top, its internal liquid level is higher than the outlet of the drain hose 23. The water in the tank flows through the first chamber 25 of the central guide pipe 16, the outlet pipe 20, the rotary joint 21, and the drain joint 22, and is discharged from the system through the drain hose 23.

[0047] Cleaning Steps: As sludge accumulates at the bottom of the tank, the top of the semi-elliptical water collector 18 contacts the sludge and applies pressure, further enhancing dewatering. Increased sludge leads to increased rotational resistance of the drive shaft 15, resulting in increased power. When the power reaches a set threshold, cleaning is required. At this point, the wastewater discharge port is closed, the rotation drive device 27 is stopped, and the lifting actuator 8 is retracted, causing the semi-cylindrical receiving tank 2 to descend onto the support roller 11. The fixing frame 12 and the arc-shaped partition plate 5 are removed, and then the rear lifting actuator 8 is extended, causing the semi-cylindrical receiving tank 2 to tilt forward. Residual wastewater in the tank is discharged first, followed by the squeezed sludge sliding down from the tank under gravity, completing self-cleaning. A small amount of attached material does not affect subsequent sludge removal, so repeated cleaning is unnecessary. The above steps are then repeated to raise the semi-cylindrical receiving tank 2 again, allowing the dewatering operation to continue.

[0048] This invention provides a wastewater treatment sludge dewatering machine. By installing a rotating semi-elliptical water collector 18 with an inlet hole 19 within a semi-cylindrical receiving tank 2, continuous separation of wastewater and sludge is achieved, while also providing sludge extrusion and dewatering functions. It can operate continuously when treating wastewater with low sludge content, requiring only cleaning of the semi-cylindrical receiving tank 2 after extended working cycles. Compared to traditional intermittent extrusion dewatering equipment, this invention significantly extends the sludge dewatering operation time and greatly reduces sludge discharge and maintenance time, thereby improving overall wastewater treatment efficiency.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
