Description

Technical Field

[0001] This invention relates to the field of sludge dewatering equipment technology, and in particular to a belt-type thickening and dewatering integrated machine for wastewater treatment and reuse. Background Technology

[0002] With increasingly stringent environmental protection requirements, the number and scale of sewage treatment plants have continued to grow, and sludge production has also increased dramatically. Sludge dewatering is a key link in the reduction and resource utilization of sewage treatment, and its treatment efficiency is directly related to the operating cost and environmental benefits of the entire sewage treatment system. Belt thickeners and dewatering machines are widely used in sludge dewatering treatment of municipal sewage and industrial wastewater due to their advantages such as large processing capacity, continuous and stable operation, and relatively low energy consumption.

[0003] Existing belt filter thickeners and dewatering machines still have many shortcomings in practical use. First, after the filter belt completes the pressure filtration and dewatering process, a large amount of adhesive sludge remains on its surface and in the fiber gaps. Conventional fixed spray cleaning systems require a large number of nozzles and a continuous high flow rate of water to achieve a basic rinsing effect, resulting in high water consumption and energy consumption. Furthermore, the fixed nozzle angle easily creates rinsing dead zones, leading to incomplete filter belt regeneration. After long-term operation, the filter belt's permeability decreases, directly affecting dewatering efficiency and cake solids content. Second, because the filter belt is always laid flat in the cleaning section, the effective rinsing width is equal to the full width of the filter belt, further exacerbating the problem of insufficient rinsing intensity per unit area. Even increasing the water supply pressure cannot fundamentally improve the cleaning effect. Furthermore, sludge from different sources varies greatly in viscosity. Existing sludge scraping devices are usually fixed structures, and the contact pressure between the scraper and the filter belt and the scraping position cannot be flexibly adjusted according to the characteristics of the sludge. When treating highly viscous sludge, the scraping effect is poor, and the residual sludge easily clogs the filter belt pores, making filter belt regeneration difficult and accelerating the aging and replacement frequency of the filter belt. To address this, we propose a belt thickening and dewatering integrated machine for wastewater treatment and reuse. Summary of the Invention

[0004] To address the problems of existing belt thickeners and dewatering machines, such as high water consumption during filter belt cleaning, dead zones during rinsing, incomplete cleaning and regeneration, and the inability of the scraping device to flexibly adjust according to sludge viscosity and adapt to different sludge treatment needs, this invention adopts the following technical solution: A belt-type thickener and dewatering integrated machine for wastewater treatment and reuse includes a mounting frame. A first filter belt is provided in the middle of the inner side of the mounting frame. A second filter belt is provided in the upper inner side of the mounting frame to provide compression operation for sludge in conjunction with the first filter belt. A first roller and a second roller are rotatably provided inside the first filter belt to provide drive path guidance for the first and second filter belts. A tail scraper is provided at the end of the first filter belt to provide front-end sludge feeding for the first filter belt. A cleaning frame is provided at the bottom inner side of the first filter belt. A shaping roller is provided on both sides of the middle section of the cleaning frame to provide shrinkage and bending guidance for the first filter belt during the cleaning stage. A belt winding and unwinding mechanism is provided on the top surface of the cleaning frame at the middle position of the first filter belt. A multi-angle rinsing unit is provided inside the cleaning frame.

[0005] Preferably, the inner surface of the first filter belt is provided with guide limiting strips at both ends, and the belt take-up and take-down mechanism includes inward stabilizing rods connected to the cleaning frame at both ends.

[0006] Preferably, both ends of the inward stabilizing rod are provided with a first sliding groove to provide guidance and limiting for the guide limiting strip, and the lower part of the inward stabilizing rod is provided with a shaping rod group whose bottom surface contacts the inner surface of the first filter belt.

[0007] Preferably, both ends of the shaping rod assembly are provided with outwardly expanding stabilizing rods that are fixedly connected to the top surface of the cleaning frame, and both ends of the outwardly expanding stabilizing rods are provided with second sliding grooves that provide guidance and limitation for the guide limiting strip.

[0008] Preferably, both ends of the outwardly expanding stabilizing rod are provided with guide strips to provide contraction limiting guidance for the guide limiting strip, and the other end of the guide strip is fixedly connected to the shaping rod assembly.

[0009] Preferably, the bottom surface of the guide strip is provided with a guide groove for mounting the guide limiting strip, and both ends of the first roller body are provided with embedded grooves for the guide limiting strip to pass through.

[0010] Preferably, a sludge guide box is fixedly installed at the bottom of the cleaning frame, and a discharge pipe is connected to the middle of the bottom surface of the sludge guide box.

[0011] Preferably, the multi-angle rinsing unit includes an angle adjustment shaft rotatably disposed inside the cleaning frame, and the angle adjustment shaft is provided with a cleaning nozzle for rinsing the surface of the first filter belt.

[0012] Preferably, the middle section of both sides of the cleaning frame is provided with an adjustment component, and the adjustment component is provided with a guide scraping mechanism located in the middle section of the lower outer surface of the first filter belt.

[0013] Preferably, the guiding scraping mechanism includes an outer scraper that is fitted with the adjusting component. The top surface of the outer scraper has a hollow cavity. An inner scraper is movably fitted inside the hollow cavity. The bottom surface of the inner scraper is provided with a main spring that is fixedly connected to it. The bottom end of the main spring is fixedly connected to the bottom surface of the hollow cavity.

[0014] Preferably, the adjusting component includes a reciprocating lead screw rotatably connected to the cleaning frame, and the outer side of the cleaning frame is provided with a drive motor whose output shaft is connected to the reciprocating lead screw. The outer scraper is threadedly fitted with the reciprocating lead screw.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves efficient dewatering through the compression and cooperation of the first and second filter belts. The belt retraction mechanism enables the first filter belt to controllably shrink and expand its projected area during the cleaning stage. The multi-angle rinsing unit improves rinsing efficiency, and the adjustable guide scraping mechanism adapts to the scraping needs of different types of viscous sludge. This invention achieves water-saving, efficient, and dead-angle-free filter belt cleaning and regeneration, significantly improving the overall operating efficiency and applicability of the equipment.

[0016] 2. By setting guide limiting strips at both ends of the inner surface of the first filter belt, and cooperating with the belt retraction and release mechanism composed of an inner stabilizing rod, a shaping rod group, an outer stabilizing rod and guide strips, the first filter belt can achieve stable wave-shaped bending and contraction along a predetermined path after entering the cleaning stage. This effectively reduces the projected area of ​​the filter belt in the cleaning frame, thereby significantly reducing the number of cleaning nozzles and working flow while ensuring the rinsing coverage rate. This significantly reduces the water consumption and energy consumption for cleaning, achieving the goal of water conservation and environmental protection.

[0017] 3. By setting up a multi-angle rinsing unit in the cleaning frame, the water outlet direction of the cleaning nozzle forms an adjustable angle with the surface of the first filter belt. The rinsing water flow impacts the surface of the filter belt at an inclined angle, which can more effectively remove residual sludge attached to the gaps between the filter belt fibers, avoid rinsing dead corners, significantly improve the cleanliness and efficiency of a single rinse, and extend the service life of the filter belt.

[0018] 4. By configuring the reciprocating screw, drive motor, and guide scraping mechanism, the inner scraper maintains gentle contact with the bottom surface of the first filter belt under the elastic force of the main spring. This effectively removes residual adhesive sludge after rinsing while avoiding damage to the filter belt surface caused by rigid contact. Furthermore, the position of the guide scraping mechanism between the middle and front sections of the cleaning frame can be flexibly adjusted via the drive motor and reciprocating screw. Low-viscosity sludge can be scraped quickly, while high-viscosity sludge can have its wetting and softening time in the rinsing area extended before scraping. This truly achieves the adaptation of the optimal scraping strategy according to different sludge characteristics, greatly expanding the applicability and treatment effect of the equipment.

[0019] In summary, this invention overcomes the shortcomings of existing technologies, achieves water-saving and efficient cleaning and regeneration without dead angles, and can be adapted to different types of viscous sludge, significantly improving dewatering efficiency and applicability, and has high social value and application prospects.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0024] Example 1: Refer to Figures 1 to 13 A belt-type thickener and dewatering integrated machine for wastewater treatment and reuse includes a mounting frame 100. A first filter belt 1 is provided in the middle of the inner side of the mounting frame 100. A second filter belt 2 is provided in the upper inner side of the mounting frame 100 to provide compression operation for sludge in conjunction with the first filter belt 1. A first roller 101 and a second roller 201 are rotatably provided inside the first filter belt 1 to provide drive path guidance for the first filter belt 1 and the second filter belt 2. A tail scraper 1001 is provided at the end of the first filter belt 1 to provide front-end sludge feeding for the first filter belt 1. A cleaning frame 6 is provided at the bottom inner side of the first filter belt 1. A shaping roller 3 is provided on both sides of the middle section of the cleaning frame 6 to provide shrinkage and bending guidance for the first filter belt 1 during the cleaning stage. A belt winding and unwinding mechanism 4 is provided on the top surface of the cleaning frame 6, located in the middle of the first filter belt 1. A box for loading filtered water is provided inside the overall closed loop of the first filter belt 1, which is a conventional setting and is not shown in the figure. A cleaning component for cleaning the surface of the second filter belt 2 is provided inside the overall closed loop of the first filter belt 1, which is a conventional setting and is not shown in the figure.

[0025] Specifically, refer to Figures 5 to 7The inner surface of the first filter belt 1 is provided with guide limiting strips 102 at both ends. The belt take-up and release mechanism 4 includes inward stabilizing rods 401 connected to the cleaning frame 6 at both ends. By setting the guide limiting strips 102, when the first filter belt 1 and the second filter belt 2 move synchronously through the first roller 101 and the second roller 201, the first filter belt 1 will not shrink its surface to an unfolded state. In conjunction with the belt take-up and release mechanism 4, the surface of the first filter belt 1 is wavy and bent during the cleaning stage, which facilitates the reduction of the projected area of ​​the first filter belt 1 during the cleaning stage, thereby reducing the number of nozzles used. This allows the integrated machine to achieve the same rinsing coverage as a conventional integrated machine with fewer nozzles and lower flow rate.

[0026] Specifically, refer to Figures 11 to 13 Both ends of the inner stabilizing rod 401 are provided with first sliding grooves 4011 to provide guidance and limit for the guide limit strip 102. The lower part of the inner stabilizing rod 401 is provided with a shaping rod group 402 whose bottom surface contacts the inner surface of the first filter belt 1. By setting the shaping rod group 402, the projected area of ​​the first filter belt 1 can be contracted, maintained and expanded during the cleaning stage, so that the projected area of ​​the first filter belt 1 can be completed during the cleaning stage, thereby reducing the rinsing projected area of ​​the bottom surface of the first filter belt 1 during the cleaning stage. The shaping rod group 402 provides shape limitation for the first filter belt 1 to contract and expand its projected area, and works with the shaping roller 3 to ensure the smoothness of the bending shape of the first filter belt 1 when it contracts, which facilitates the subsequent cleaning of its surface without dead angles.

[0027] Specifically, refer to Figures 9 to 12 Both ends of the shaping rod assembly 402 are provided with outwardly expanding stabilizing rods 403 that are fixedly connected to the top surface of the cleaning frame 6. Both ends of the outwardly expanding stabilizing rods 403 are provided with second sliding grooves 4031 that provide guidance and limitation for the guide limiting strip 102. Through the setting of the outwardly expanding stabilizing rods 403 and the second sliding grooves 4031, in conjunction with the setting of the guide limiting strip 102, a guiding function is provided for the first filter belt 1 when it initially enters the cleaning stage and exits the cleaning stage.

[0028] Specifically, refer to Figure 11 and Figure 12 Both ends of the outward expansion stabilizing rod 403 are provided with guide strips 404 to provide shrinkage limiting guidance for the guide limiting strips 102. The other end of the guide strips 404 is fixedly connected to the shaping rod group 402. By setting the guide strips 404, when the first filter belt 1 passes through the outward expansion stabilizing rod 403 to reach the inward contraction stabilizing rod 401 and from the inward contraction stabilizing rod 401 to the outward expansion stabilizing rod 403, the guide limiting strips 102 at both ends of the first filter belt 1 can provide guiding and limiting operation, so that the first filter belt 1 can provide stable shrinkage and unfolding path limiting and guiding function in the above two stages, avoiding excessive twisting or incomplete shrinkage of the first filter belt 1 during shrinkage, and incomplete unfolding or over-expansion during unfolding.

[0029] Specifically, refer to Figure 5 and Figure 12 The bottom surface of the guide bar 404 is provided with a guide groove 4041 for mounting the guide limiting bar 102. Both ends of the first roller body 101 are provided with embedded grooves 1011 for the guide limiting bar 102 to pass through. By setting the embedded grooves 1011, when the first roller body 101 drives the first filter belt 1 to rotate, the surface of the first roller body 101 is prevented from directly contacting the guide limiting bar 102, providing a passage area for the guide limiting bar 102, so that the first filter belt 1 can perform a perfect squeezing and filtration cooperation with the second filter belt 2.

[0030] Example 2: Refer to Figures 1 to 13 The difference between this embodiment and embodiment 1 is that a sludge guide box 5 is fixedly installed at the bottom of the cleaning frame 6. A discharge pipe 51 is connected to the middle of the bottom surface of the sludge guide box 5. Through the setting of the sludge guide box 5, the sewage and a small amount of sludge that fall off when cleaning the first filter belt 1 will fall into the interior of the sludge guide box 5. Then, through the discharge pipe 51, it is connected to the external pipeline to collect the sewage and sludge in a centralized manner.

[0031] Specifically, refer to Figure 6 and Figure 7 The multi-angle rinsing unit includes an angle adjustment shaft 61 rotatably disposed inside the cleaning frame 6. The angle adjustment shaft 61 is provided with a cleaning nozzle 611 for rinsing the surface of the first filter belt 1. By setting the angle adjustment shaft 61 and cooperating with the cleaning nozzle 611, the rinsing angle between the water outlet end of the cleaning nozzle 611 and the surface of the first filter belt 1 can be adapted and adjusted so that there is an angle between the two, making it easier to rinse the attached substances on the surface of the first filter belt 1 and make the attached substances fall off.

[0032] Specifically, refer to Figure 6 and Figure 7 The cleaning frame 6 has adjustment components 7 on both sides of the middle section. The adjustment components 7 are equipped with a guide scraping mechanism 71 located in the middle section of the lower outer surface of the first filter belt 1. The guide scraping mechanism 71 can firstly work with the shaping rod group 402 to stabilize the shape of the first filter belt 1 in the middle section of the cleaning stage, keeping the bottom surface of the first filter belt 1 smooth, so that the cleaning nozzle 611 can perform a thorough rinsing operation on the bottom surface of the first filter belt 1. Secondly, the guide scraping mechanism 71 can scrape off the remaining small amount of sludge on the bottom surface of the first filter belt 1, thereby improving the rinsing efficiency.

[0033] Specifically, refer to Figure 8 and Figure 9The guide scraping mechanism 71 includes an outer scraper 7101 fitted with the adjustment assembly 7. A hollow cavity 7102 is provided on the top surface of the outer scraper 7101. An inner scraper 7103 is movably fitted inside the hollow cavity 7102. A main spring 7104 is fixedly connected to the bottom surface of the inner scraper 7103. The bottom end of the main spring 7104 is fixedly connected to the bottom surface of the hollow cavity 7102. By setting the guide scraping mechanism 71, it is possible to avoid the top of the inner scraper 7103 from causing a hard collision with the bottom surface of the first filter belt 1 and damaging the surface of the first filter belt 1.

[0034] Specifically, refer to Figure 9 and Figure 10 The adjusting assembly 7 includes a reciprocating screw 701 rotatably connected to the cleaning frame 6. A drive motor 702 with an output shaft connected to the reciprocating screw 701 is provided on the outer side of the cleaning frame 6. An outer scraper 7101 is threadedly fitted to the reciprocating screw 701. Through the arrangement of the reciprocating screw 701 and the drive motor 702, the guiding scraping mechanism 71 can move between the middle and front sections between the two shaping rollers 3. When the guiding scraping mechanism 71 is in such a position... Figure 9 As shown in the previous section, the guide scraping mechanism 71 is adapted to scraping sludge with weak adhesion. When the guide scraping mechanism 71 is in such a position... Figure 6 and Figure 7 In the middle section shown, the spray head increases the rinsing time on the bottom surface of the first filter belt 1, thereby increasing the wetting and softening time of the sludge. This makes it easier for the hollow chamber 7102 to scrape off the more viscous sludge, allowing the guide scraping mechanism 71 to adjust its scraping position according to the viscosity of different sludge, adapting to different usage requirements.

[0035] Other undescribed structures are described in Example 1.

[0036] Working principle: In this invention, sludge falls onto the top surface of the first filter belt 1 and spreads evenly on its upper surface. The first filter belt 1 and the second filter belt 2 move synchronously under the driving guidance of the first roller 101 and the second roller 201, respectively, forming an upper and lower clamping of the sludge. Through the S-shaped pressure filtration operation, as the first roller 101 and the second roller 201 guide the path, the gap between the two filter belts gradually decreases, so that the sludge sandwiched in it is subjected to gradually increasing squeezing and shearing forces, thereby quickly removing most of the free water from the sludge and completing the preliminary pressure filtration process of concentration and dewatering.

[0037] After dewatering by pressure filtration, the sludge is in the form of a mud cake. It eventually moves to the end with the first filter belt 1, where it is scraped off the surface of the filter belt by the tail scraper 1001 and discharged from the equipment, completing the dewatering and discharge of the sludge. After unloading, the first filter belt 1 continues to move downwards and enters the cleaning and regeneration stage.

[0038] Upon entering the cleaning stage, the first filter belt 1 first enters the area of ​​the belt take-up and undo mechanism 4. Subsequently, it passes through the shaping rollers 3 on both sides of the middle section of the cleaning frame 6 and begins to shrink and bend under the guidance of the shaping rollers 3. Specifically, the guide limiting strips 102 at both ends of the inner surface of the first filter belt 1 pass sequentially through the second sliding groove 4031 on the outward expansion stabilizing rod 403, the guide groove 4041 on the bottom surface of the guide strip 404, and then enter the first sliding groove 4011 on the inward contraction stabilizing rod 401. During this process, the bottom surface of the shaping rod group 402 remains in contact with the inner surface of the first filter belt 1. With the limiting guidance of the guide strip 404, the first filter belt 1 presents a stable wavy bending state during the cleaning stage, achieving a reduction in the projected area. This design significantly reduces the effective rinsing width of the first filter belt 1 within the cleaning frame 6, thereby significantly reducing the number of cleaning nozzles 611 and the working flow rate while ensuring rinsing coverage.

[0039] At the same time, the multi-angle rinsing unit inside the cleaning frame 6 starts working. The angle adjustment shaft 61 can drive the cleaning nozzle 611 to rotate according to the actual working conditions, adjusting the angle between its water outlet direction and the surface of the first filter belt 1, so that the rinsing water flow impacts the surface of the filter belt at an inclined angle, which is more conducive to removing residual sludge attached to the gaps between the filter belt fibers. Since the projected area of ​​the first filter belt 1 has shrunk, the rinsing range of the cleaning nozzle 611 is concentrated, the rinsing intensity per unit area is increased, and the cleaning effect is enhanced.

[0040] During the rinsing process, the guide scraping mechanism 71 located in the middle section of the lower outer surface of the first filter belt 1 simultaneously participates in the cleaning operation. The outer scraper 7101 of the guide scraping mechanism 71 is mounted on the reciprocating screw 701. The drive motor 702 drives the outer scraper 7101 to move between the middle section and the front section between the two shaping rollers 3 through the reciprocating screw 701. When the first filter belt 1 is moving, the guide scraping mechanism 71 remains stationary. The inner scraper 7103 is movably mounted in the hollow cavity 7102 on the top surface of the outer scraper 7101. Under the elastic force of the main spring 7104, the inner scraper 7103 always maintains a gentle contact with the bottom surface of the first filter belt 1, which can effectively scrape off the adhering sludge remaining after rinsing, while avoiding damage to the surface of the filter belt due to rigid contact. The position of the guide scraping mechanism 71 can be adjusted by driving motor 702 and reciprocating screw 701, and the scraping position can be flexibly adjusted according to the characteristics of sludge. When the sludge being processed has low viscosity, the guide scraping mechanism 71 is in the front position to achieve rapid scraping. When the sludge being processed has high viscosity, it is moved to the middle position to extend the time for the sludge to be wetted and softened by the cleaning nozzle 611 in the rinsing area, so that the sludge is fully wetted and softened before being scraped, thereby improving the scraping effect and adapting to different working conditions.

[0041] Wastewater and a small amount of residual sludge generated during rinsing and scraping fall into the lower sludge guide box 5, and are connected to the external collection pipeline through the discharge pipe 51 in the middle of the bottom surface of the sludge guide box 5, so as to achieve centralized discharge and treatment and effectively avoid secondary pollution.

[0042] After being cleaned and scraped, the first filter belt 1 continues to move forward. Under the guidance of the belt winding and unwinding mechanism 4, it gradually unfolds from a contracted and bent state, and is restored to flatness by the guidance of the outward expansion stabilizing rod 403 and the shaping roller 3. Then it re-enters the filter pressing working area and enters the next dewatering cycle.

[0043] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
