Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sewage treatment, and particularly relates to an integrated sewage treatment equipment. BACKGROUND

[0002] The integrated sewage treatment equipment is often applied in municipal and industrial fields due to small land occupation and high integration, wherein the filtration link is a key step for removing suspended matters (such as silt, fiber and particulate impurities) in sewage, and directly affects the operation efficiency of a subsequent treatment unit and the service life of the equipment. At present, the filtration structure of a commercially available integrated sewage treatment equipment mainly adopts two types of technical solutions: one type is a fixed filter plate which directly intercepts impurities through static filter holes, and is simple in structure and low in cost, and is suitable for a stable flow scene; and the other type is a simple rotating filter device which rotates the filter plate as a whole around a single axis through a motor, and uses centrifugal force to assist in discharging the intercepted impurities, and to a certain extent, improves the filtration capacity under large flow.

[0003] However, the inventor finds that the above prior art still has significant defects in actual application: the fixed filter plate cannot dynamically adjust the motion trajectory of the filtration surface according to flow fluctuation because the filter holes are static, when the sewage flow increases or the suspended matter concentration increases, the local pressure of the filter holes will be uneven, which will accelerate the accumulation of impurities, resulting in rapid increase of filtration resistance, and even a "short circuit" phenomenon occurs, that is, part of the sewage directly flows out without effective filtration, and the simple rotating filter device enhances the centrifugal force through rotation, but the motion mode of the filter plate is single-axis revolution, and the flow field formed is concentrated at the edge of the filter plate, and "low-speed dead zones" are easily formed in the central region and near the filter holes, resulting in that part of the impurities are not effectively intercepted and pass through the filter holes, or are deposited on the back of the filter plate and are difficult to remove, and after long-term operation, the problems of decreased filtration efficiency and frequent filter hole blockage still occur, and therefore, there is an urgent need for an integrated sewage treatment to solve these problems. SUMMARY

[0009] As a further scheme of the utility model, the two ends of the guide part are respectively hinged to the positions one third of the top walls of the adjacent two rotating plates.

[0010] As a further scheme of the utility model, a plurality of second filter holes are arranged on the ring-shaped filter plate inside the first circular ring, a second filter hole is arranged at the position closest to the inner wall of the first circular ring on the ring-shaped filter plate, the remaining second filter holes are symmetrically distributed to both sides along the circumference of the ring-shaped filter plate with the second filter hole as the center, and the diameters of the second filter holes decrease in turn from the center to both sides.

[0015] The present application has the following beneficial effects: The design of the integrated sewage treatment device solves many problems encountered by the existing fixed filter plate and simple rotating filter device in treating sewage. Firstly, for the impurity accumulation, resistance increase and sewage "short circuit" phenomenon caused by the static filter hole of the fixed filter plate when the flow fluctuates, the device adopts a filtering unit with an eccentric ring-shaped guide part. The design of the blade assembly in the filtering unit enables each rotating plate to perform a combined motion of revolution and rotation. When the rotating block revolves around the central axis of the filtering part, the sliding block slides in the guide rail of the eccentric ring-shaped guide part, which drives the rotating plate to rotate around its own axis. This combined motion effectively breaks the static state near the filter hole, so that impurities are not easy to accumulate around the filter hole, thereby reducing the filtering resistance and avoiding the "short circuit" phenomenon of sewage. At the same time, the device solves the problem of "low-speed dead zone" formed in the center of the filter plate and near the filter hole due to the single revolution motion of the simple rotating filter device. Since the rotating plate can rotate while revolving, this double motion increases the flow rate on the surface of the filter plate, making it more difficult for impurities to deposit in the central area or near the filter hole. In this way, the filtering efficiency is significantly improved, and the problem of frequent blockage caused by impurities penetrating or depositing is reduced. The integrated sewage treatment device realizes the combined motion of revolution and rotation of the filter plate in the filtering process through the unique design of the blade assembly, effectively improves the filtering efficiency, reduces the filtering resistance, and reduces the blockage phenomenon, providing a more efficient and reliable technical solution for sewage treatment.

DETAILED DESCRIPTION

[0019] In order to further illustrate the technical means adopted by the present application and the effects achieved by the present application in realizing the predetermined object of the present application, the specific embodiments, structures, features and effects according to the present application are described in detail below in combination with the drawings and preferred embodiments.

[0020] Reference Figure 1 - Figure 5 The present embodiment provides an integrated sewage treatment device, which comprises a device main body 1 and a filter unit 2 arranged in the device main body 1. The filter unit 2 comprises a filter part 21 arranged in the device main body 1, an eccentric ring-shaped guide part 26 arranged on the filter part 21, a rotating part 23, a plurality of support parts 24 and a vane assembly 25 arranged on each of the support parts 24. The rotating part 23 is arranged at the center of the filter part 21, and the plurality of support parts 24 are circumferentially and uniformly arranged on the rotating part 23. The vane assembly 25 comprises a rotating plate 251 arranged perpendicularly on the support part 24 and a rocker 252. One end of the rocker 252 is rotatably penetrated through the end of the support part 24 and is fixedly connected with the rotating plate 251. The other end of the rocker 252 is hingedly connected with a sliding block 27. The sliding block 27 is embedded in the guide rail 221 of the eccentric ring-shaped guide part 26 and can slide along the guide rail 221. Adjacent two rotating plates 251 form a group. The two rotating plates 251 of each group are connected through the guide part 26. The rotating block is driven by a driving member to revolve around the central axis of the filter part 21. The sliding block 27 slides in the guide rail 221 and drives the rotating plate 251 to rotate around its own axis, so that the rotating plate 251 synchronously generates a combined motion of revolution and rotation. A rotating shaft 6 is arranged below the filter unit 2. The rotating shaft 6 is connected with the driving shaft of a waterproof motor 3 below and is connected with the rotating part 23. The waterproof motor 3 drives the rotating part 23 to rotate through the rotating shaft 6, as shown in FIG. 2. Figure 1 .

[0021] Need to be supplemented is that the slider 27 is embedded in the eccentric ring guide 221, when the rotating part 23 revolves, the slider 27 is forced to move radially by the geometric constraint of the guide 221, the linear displacement is converted into the rotation torque of the rotating plate 251 through the rocker 252, the curvature change of the eccentric guide 221 dynamically adjusts the rotation speed of the blade with the revolution position, forms a non-uniform turbulent flow on the surface of the filter plate, completely destroys the "low-speed dead zone", the rotating plate 251 is rigidly connected with the rotating part 23 to realize revolution through the support part 24, and is forced to rotate through the rocker 252 and the slider 27 mechanism, forming a planetary motion trajectory, the centrifugal force of revolution throws large particles to the edge of the device, reducing the load of the filter hole; The edge line speed difference of the blade during rotation forms a fluid shear layer, continuously peeling off the attached micro-particles of the filter hole, when the flow increases, the water flow impact force increases, the blade rotation speed increases, and the turbulent flow intensity automatically increases, avoiding the "short circuit" phenomenon, the two rotating plates 251 of each group are connected through the guide part 26, and the same group of blades is forced to maintain the same deflection angle, avoiding motion interference and ensuring the stability of the flow field; At the same time, it can also resist the vibration of the blade caused by the impact of sewage, prolonging the service life of the mechanism.

[0022] At present, the integrated sewage treatment equipment is widely used in municipal, industrial and other fields due to small occupation and high integration, and its filtering link is a key step for removing suspended solids (such as silt, fiber and particulate impurities), which directly affects the subsequent treatment efficiency and equipment life. The existing filtering structure mainly adopts two schemes: one is a fixed filter plate, which intercepts impurities through static filter holes, and is suitable for stable flow scenes, but cannot dynamically adjust the motion trajectory of the filter surface. When the flow increases or the concentration of suspended solids increases, the local pressure of the filter hole will be uneven, which will accelerate the accumulation of impurities, resulting in a sudden increase in filtering resistance or even "short circuit" (part of the sewage flows out without effective filtering). The second is a simple rotating filter device, which drives the filter plate to rotate as a whole around a single axis through a motor, and uses centrifugal force to assist in removing impurities. Although it improves the large-flow filtering capacity, the flow field formed by the single revolution is concentrated on the edge of the filter plate, and "low-speed dead zone" is easy to occur in the central region and near the filter hole, resulting in incomplete interception of impurities and difficult removal of deposits. Long-term operation will still have problems of decreased filtering efficiency and frequent filter hole blockage.

[0023] To solve the above problems, in the embodiment, the above problems are solved by the composite motion mechanism of the vane assembly 25: the driving member drives the rotating part 23 to drive the supporting part 24 to revolve around the center axis of the filtering part 21, and the slider 27 slides in the eccentric annular guide rail 221, and the rocker 252 forces the rotating plate 251 to rotate around its own axis, which makes the rotating plate 251 rotate synchronously during revolution, breaks the traditional single motion mode, generates local turbulence by rotation, disturbs the fluid near the filter hole center and the filter hole, prevents impurities from depositing in the “low-speed dead zone”, and the revolution centrifugal force throws the impurities to the edge, and the shear effect of rotation continuously peels off the impurities attached to the surface of the filter hole, avoids the accumulation caused by uneven local pressure, adapts to the flow fluctuation, and the three-dimensional flow field formed by the composite motion can automatically adjust the disturbance intensity according to the water flow speed, and the higher the flow speed, the faster the vane rotates, dynamically maintains the filtering efficiency, the eccentric annular guide rail 221 converts the revolution kinetic energy into rotation torque, realizes the cooperation of double motions under a single driving source, and fundamentally solves the problems of “dead zone” and “static jamming”.

[0024] In the traditional sewage treatment equipment, the rotating part 23 and the guide part 26 of the filtering unit 2 are often designed to have complex structure, high processing difficulty, unstable operation, high maintenance cost and other problems, which makes it difficult for the equipment to achieve efficient, stable and economic operation effect in actual application. To solve this problem, in an embodiment, the eccentric annular guide part 26 includes a first circular ring 222 and a second circular ring 223, the first circular ring 222 and the second circular ring 223 are arranged on the filtering part 21, the first circular ring 222 and the second circular ring 223 are concentrically arranged and the diameter of the first circular ring 222 is smaller than the diameter of the second circular ring 223, the outer wall of the first circular ring 222 and the inner wall of the second circular ring 223 directly form a guide rail 221 for sliding of the guide block, in order to solve the problem of complex structure and difficult installation of the guide part 26 in the traditional equipment, the eccentric annular guide part 26 is designed, which can simplify the structure and reduce the processing difficulty, the eccentric annular guide part 26 is arranged to enable the slider 27 to slide in the guide rail 221, thereby realizing the composite motion of revolution and rotation of the rotating plate 251, the eccentric annular guide part 26 is concentrically arranged by the first circular ring 222 and the second circular ring 223, and the closed guide rail 221 is formed by the gap between the inner and outer walls, which eliminates the installation step of the independent guide rail 221 and simplifies the processing process, in addition, the double circular rings are rigidly fixed on the filtering part 21, which avoids the eccentric error of the guide rail 221 caused by welding deformation and ensures the accuracy of the sliding track of the slider 27.

[0025] It is worth mentioning that in order to ensure that the existing fixed filter plate is not affected by the filtration effect and needs to be treated in a targeted manner for the actual filtration situation while solving the problem of impurity accumulation, resistance rise and sewage "short circuit" phenomenon caused by filter hole static when flow fluctuates, and the problem of impurity penetration or deposition caused by the formation of "low-speed dead zone" near the center of the filter plate and the filter hole due to single revolution of the simple rotating filter device, resulting in reduced filtration efficiency and frequent blockage, in an embodiment, the filter part 21 is a ring-shaped filter plate, a plurality of first filter holes 224 are arranged on the ring-shaped filter plate outside the second circular ring 223, a plurality of filter holes are arranged in an arc shape on the ring-shaped filter plate, and a first filter hole 224 is arranged at the position farthest from the outer wall of the second circular ring 223 on the ring-shaped filter plate. Take the first filter hole 224 as the center, and symmetrically distribute the remaining first filter holes 224 to both sides along the circumference of the ring-shaped filter plate, and the diameter of the first filter hole 224 decreases from the center to both sides in turn, a plurality of second filter holes 225 are arranged on the ring-shaped filter plate inside the first circular ring 222, and a second filter hole 225 is arranged at the position closest to the inner wall of the first circular ring 222 on the ring-shaped filter plate. Take the second filter hole 225 as the center, and symmetrically distribute the remaining second filter holes 225 to both sides along the circumference of the ring-shaped filter plate, and the diameter of the second filter hole 225 decreases from the center to both sides in turn, wherein the diameter of the first filter hole 224 is smaller than that of the second filter hole 225, as shown in Figure 3 , the outer ring outside the second circular ring 223 is provided with small-diameter first filter holes 224, and the inner ring inside the first circular ring 222 is provided with large-diameter second filter holes 225, and the hole diameter decreases from the center to both sides. When the equipment is running, the outer ring has large revolution radius, high linear velocity and strong centrifugal force, and large-particle impurities are thrown to the outer edge. The small-pore filter hole arranged here can efficiently intercept small particles enriched by centrifugal force, the inner ring is a low linear velocity area, and the fluid linear velocity in the central region is low, which is easy to form deposition. Large-pore filter holes are used to reduce flow resistance and prevent impurity accumulation and blockage, while allowing part of the small particles to pass through to the subsequent processing unit. In addition, the flow rate is lowest at the position farthest or closest to the circular ring wall, and the flow rate increases symmetrically to both sides. The filter holes with decreasing diameter are arranged to increase the flux in the low flow rate area to avoid blockage, and the pore size is reduced in the high flow rate area to improve the interception precision, dynamically balancing the filtration efficiency and anti-blocking property. The second circular ring 223 is tangent to the edge of the filter part 21, that is, the second circular ring 223 is an inscribed circle of the filter part 21, as shown in Figure 3 .

[0026] Since the impact force of the fluid on the plate surface changes when the rotating plate 251 is simultaneously subjected to a compound motion, the fluid dynamic pressure is unevenly distributed, and such uneven fluid dynamic pressure generates different forces at different parts of the rotating plate 251, resulting in unstable torque acting on the plate surface, thereby causing the rotating plate 251 to lose stability in the compound motion. In addition, the fluid interaction under different motion combinations is complex and is prone to interference, further increasing the risk of motion interference. To avoid this problem, in an embodiment, the two ends of the guide portion 26 are respectively hinged to the top wall of the adjacent two rotating plates 251 at one-third of the top wall, and the hinging of the two ends of the guide portion 26 to the top wall of the adjacent two rotating plates 251 at one-third of the top wall forms a lever fulcrum, which can effectively constrain the synchronous deflection of the rotating plates 251 in the same group. This design helps to offset the impact torque generated by the uneven fluid dynamic pressure, thereby maintaining the stability of the rotating plate 251 in the compound motion. Since the design adopts a hinged structure, when the rotating plate 251 needs to be maintained or replaced, it can be operated more conveniently, thereby reducing the maintenance cost and downtime.

[0027] To prevent flow field disorder when the rotating plate 251 is in motion and thereby improve the filtering efficiency, in an embodiment, the rotating plate 251 is a rectangular plate, the number of the rotating plates 251 is six, and the six rotating plates 251 are arranged in parallel. The number of the rotating plates 251 is set to six mainly based on the comprehensive optimization of fluid mechanics uniformity, motion coordination, and structural stability: first, the circumference of the annular filter plate is fixed, and the six rotating plates 251 are evenly distributed in the circumferential direction, with one plate arranged every 60°, which can uniformly distribute the impact force of the water flow on the surface of the filter plate, avoid the formation of turbulent dead zones caused by excessively high or low local flow rates, ensure the balanced distribution of fluid dynamic pressure in each area of the plate surface, and reduce the risk of instability of the rotating plate 251 caused by uneven dynamic pressure; second, the parallel and symmetrical arrangement of the six rotating plates 251 can effectively match the geometric constraints of the eccentric annular guide portion 26. The lever fulcrum structure formed by the hinging of the two ends of the guide portion 26 to the top wall of the adjacent rotating plates 251 at one-third of the top wall can synchronously constrain the deflection angle of the rotating plates 251 in the same group, ensure the high synchronization of the rotation and revolution of each plate in the compound motion, and avoid motion interference; third, the six-equal-part design of the rectangular plate optimizes the structural rigidity and strength while ensuring the filtering area: the reasonable spacing between the adjacent plates can reduce the resistance loss of the fluid flow and provide sufficient support for the rigid connection of the rotating plates 251, thereby reducing the risk of deformation during high-speed revolution and rotation; and fourth, the number of the six rotating plates 251 balances the filtering efficiency and driving energy consumption. Too few plates, such as four plates, can cause water flow impact concentration and increase the filtering blind area, and too many plates, such as eight plates, can increase the moment of inertia and manufacturing complexity. The design of six plates meets the requirements of dynamically adjusting the motion trajectory of the filtering surface, breaking the "low-speed dead zone", and taking into account the economy and reliability of the equipment operation.

[0028] Further, in order to avoid the problem of insufficient waterproof performance of the driving member, unstable operation caused by deviation of the driving shaft and the rotating part 23, in an embodiment, the driving member is a waterproof motor 3, the output shaft of the waterproof motor 3 penetrates through the bottom of the device main body 1 vertically and is coaxially connected with the rotating part 23, and the axis of the waterproof motor 3 coincides with the central axis of the filtering part 21. If a conventional device uses a general motor or a driving shaft offset design, the motor is easily damaged by water entering from the humid environment inside the device, or the rotating part 23 is stuck in revolution and the motion track of the blade assembly 25 is distorted due to the axis deviation, affecting the synchronicity of the combined motion. Here, by using the waterproof motor 3 and ensuring that the output shaft is completely coincident with the central axis of the rotating part 23 and the filtering part 21, the sealing performance of the driving system can be effectively improved, and the motor can be prevented from being damaged by water entering from the sewage. At the same time, the coaxial connection eliminates the transmission gap, ensures the stability of the revolution of the rotating part 23, and makes the revolution and rotation combined motion of the blade assembly 25 more accurate, avoiding fluctuations in filtering efficiency or abnormal wear of the structure caused by driving deviation, and prolonging the overall service life of the device.

[0029] Further, in order to solve the problem of large sliding friction loss and high motion resistance of the sliding block 27 and the guide rail 221, in an embodiment, the bottom of the sliding block 27 is provided with a rotatable roller, the roller is embedded in the guide rail 221 of the eccentric ring-shaped guide part 26, and the cross section of the roller rim is matched with the concave-convex section of the guide rail 221. In a conventional design, when the sliding block 27 directly slides in the guide rail 221, the sliding friction between metals or hard materials will generate a large resistance, not only increasing the driving energy consumption, but also accelerating the wear of the guide rail 221 and the sliding block 27, causing the sliding block 27 to be stuck in motion and the positioning accuracy to be reduced, affecting the coordination of the rotation of the rotating plate 251 and the revolution. By adding a rotatable roller, the sliding friction is converted into rolling friction, greatly reducing the motion resistance and making the sliding of the sliding block 27 in the guide rail 221 smoother. At the same time, the concave-convex matching design of the roller rim and the cross section of the guide rail 221 enhances the contact stability, avoids the deviation or jumping of the sliding block 27 in the guide rail 221, ensures the accurate control of the rotation angle of the rotating plate 251, and further improves the stability of the combined motion, reduces the frequency of replacement of parts caused by friction loss, and reduces the maintenance cost.

[0030] In order to avoid the sludge deposition of the device to be difficult to discharge, the filter hole cleaning is not complete, and for this, in an embodiment, the bottom of the device body 1 is provided with a conical sludge collecting hopper 4, the side wall of the conical sludge collecting hopper 4 is provided with an ultrasonic vibrator, the upper part of the filter part 21 is provided with a detachable flushing pipe 5, the nozzle of the flushing pipe 5 is arranged in a spiral shape, the bottom of the device body 1 is provided with a conical sludge collecting hopper 4, the side wall of the conical sludge collecting hopper 4 is provided with an ultrasonic vibrator, the upper part of the filter part 21 is provided with a detachable flushing pipe 5, the nozzle of the flushing pipe 5 is arranged in a spiral shape, during the operation of the sewage treatment device, the large particle impurities thrown to the outer edge are easy to accumulate at the bottom of the device to form a sludge layer, if not cleaned in time, the filter hole will be blocked or the rotating part 23 will be affected; at the same time, the micro-particles attached to the surface of the filter hole are difficult to be removed by conventional flushing, and long-term accumulation will cause the filter resistance to increase sharply or even "short circuit", the conical sludge collecting hopper 4 is arranged here, which can guide the sludge to the center by the inclined inner wall, and the sludge is loosened by the vibration of the ultrasonic vibrator on the side wall, so that the sludge is easily discharged; the detachable flushing pipe 5 above the filter part 21 can form a rotating water flow through the spiral nozzle, and the filter hole is subjected to omnidirectional high-pressure flushing, so that the attached micro-particles are effectively stripped; the detachable design also facilitates the maintenance or replacement of the flushing pipe 5, ensures the cleaning effect to be durable and stable, significantly improves the self-cleaning ability and anti-blocking performance of the device, and reduces the frequency of manual cleaning.

[0031] The working principle and working process of the present application: The rotating part 23 is driven by the waterproof motor 3 to drive the supporting part 24 to revolve around the central axis of the filter part 21, at the same time, the slider 27 is constrained by the eccentric ring guide 221 to produce radial displacement, the linear motion is converted into the self-rotation torque of the rotating plate 251 through the rocker 252, the composite motion makes the six rectangular rotating plates 251 simultaneously perform planetary revolution and rotation, the revolution centrifugal force throws the large particle impurities to the edge of the device, and the load of the filter hole is reduced; the rotation forms a dynamic shear layer on the surface of the filter plate, continuously stripping the attached micro-particles of the filter hole, the curvature change of the eccentric guide 221 automatically adjusts the rotation speed of the blade with the revolution position, generates non-uniform turbulent flow in the filtering area, completely destroys the "low-speed dead zone" in the central area and near the filter hole, when the sewage flow increases, the water flow impact force is enhanced to drive the blade rotation to accelerate, the turbulent flow intensity is simultaneously improved, the filtering efficiency is adaptively maintained, and the "short circuit" phenomenon caused by impurity accumulation is avoided; The sewage first enters the equipment main body 1, when flowing through the annular filter plate, the outer ring small aperture filter hole intercepts the small particles enriched in the high-speed centrifugal area, the inner ring large aperture filter hole reduces the flow resistance in the low linear speed area; the conical sludge collecting hopper 4 collects the sludge separated by the centrifugal force, the side wall ultrasonic vibrator periodically vibrates to prevent hardening; the filter unit 2 continuously runs, the detachable flushing pipe 5 sprays the rotating water flow through the spiral arrangement nozzle to perform the three-dimensional high-pressure back flushing on the filter hole; the finally purified water flows out of the equipment, and the deposited sludge is discharged through the sludge collecting hopper bottom. The closed loop system realizes the full-process automation of filtering, sludge discharge and self-cleaning through the synergistic effect of mechanical movement and fluid dynamics.
