Description

Technical Field

[0001] This utility model relates to the field of wastewater purification technology, and in particular to a multi-stage filtration industrial wastewater purification device. Background Technology

[0002] Wastewater purification is a process that uses physical, chemical, and biological technologies to treat wastewater generated in domestic, industrial, and agricultural sectors. It removes suspended impurities, organic pollutants, heavy metal ions, pathogens, and other harmful components from the water, ensuring that the water quality meets discharge standards or reuse requirements. Its core objectives are twofold: firstly, to reduce the pollution of soil, rivers, and groundwater caused by wastewater discharge, protecting water resources and ecological balance; and secondly, to achieve water resource recycling and alleviate water shortage pressures.

[0003] Industrial wastewater purification requires preliminary filtration of large particulate impurities on the inner wall before subsequent fine filtration. Existing large-particle filters require regular cleaning after prolonged use, which can lead to filtration interruptions, affecting subsequent purification and reducing wastewater purification efficiency.

[0004] Therefore, a multi-stage filtration industrial wastewater purification device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-stage filtration industrial wastewater purification device, which aims to improve the existing technology where large particle filter screens require regular cleaning after long-term use, resulting in filtration interruption, affecting subsequent purification, and reducing the efficiency of wastewater purification.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A multi-stage filtration industrial wastewater purification device includes: a filter tank, an inclined box fixedly installed inside the filter tank, a motor fixedly installed on one side of the inclined box, a first rotating rod fixedly connected to the output end of the motor, the other end of the first rotating rod being movably connected to the surface of the inner wall of the inclined box via a bearing seat, a second rotating rod movably connected inside the inclined box, filter screens being provided on the surfaces of the first and second rotating rods, and a cleaning mechanism being provided on the outside of the inclined box for cleaning the filter screens.

[0007] Through the above technical solutions, the filter tank provides a stable bearing and treatment space for industrial wastewater purification, ensuring the integrity of the overall structure of the device; the tilting structure of the tilting box can guide the wastewater to flow along a preset path, prolonging the residence time of the wastewater in the filtration area and improving filtration efficiency; the motor drives the first rotating rod to rotate, which, together with the second rotating rod, drives the filter screen to operate, realizing the dynamic interception of suspended impurities in the wastewater and preventing impurities from accumulating locally; the cleaning mechanism can clean the filter screen in a timely manner, maintaining the permeability of the filter screen and ensuring the continuous and stable operation of the device.

[0008] As a further description of the above technical solution: the cleaning mechanism includes two fixed plates, which are fixedly installed at higher positions on both sides of the tilting box. A rotating roller is movably connected to the inner side of one of the fixed plates through a bearing seat. The other end of the rotating roller passes through the other fixed plate and is movably connected to the fixed plate through a stabilizing bearing.

[0009] Through the above technical solution, two fixed plates are fixed at a higher position on the inclined box, providing a stable support for the rotating roller and ensuring the positional stability of the rotating roller during operation; the rotating roller is movably connected to the fixed plate through the bearing seat, which can reduce the frictional resistance during rotation, making the rotating roller run more smoothly and reducing power loss; the stabilizing bearing further enhances the connection stability of the rotating roller, preventing the rotating roller from shaking or deviating when running at high speed, and ensuring the orderly progress of cleaning operations.

[0010] As a further description of the above technical solution: the surface of the rotating roller is fixedly connected with a brush, and the number of the brushes is several and they are evenly distributed in a ring.

[0011] Through the above technical solution, the brushes fixed on the surface of the rotating roller can directly contact the surface of the filter screen and remove impurities attached to the filter screen through physical friction; several brushes are evenly distributed in a ring, which can cover the entire circumference of the rotating roller, and thoroughly clean the filter screen when the rotating roller is running, avoiding cleaning dead corners caused by uneven distribution of brushes, and ensuring that the permeability of the filter screen is consistent throughout.

[0012] As a further description of the above technical solution: a worm gear is fixedly connected to the surface of the rotating roller, a worm is meshed with the surface of the worm gear, and a motor is fixedly installed at one end of the worm.

[0013] Through the above technical solution, the worm gear and worm on the surface of the rotating roller mesh with each other, which can stably transmit the power output by the motor to the rotating roller. The structural characteristics of the worm drive have a self-locking function, which can prevent the rotating roller from rotating in the opposite direction due to external force, ensuring the stable operation of the cleaning operation. The motor provides a continuous and controllable power source for the worm, and the rotation speed can be adjusted according to the amount of impurities attached to the filter screen to adapt to different cleaning needs.

[0014] As a further description of the above technical solution: a first support plate and a second support plate are fixedly installed on the surface of one of the fixed plates.

[0015] Through the above technical solution, the first support plate and the second support plate on the surface of the fixed plate can provide independent support points for the power components and transmission components to be installed later, so that the installation position of each component is more accurate.

[0016] As a further description of the above technical solution: the motor is fixedly connected to the first support plate, and the end of the worm gear away from the motor is movably connected to the second support plate through a bearing seat.

[0017] Through the above technical solution, the motor is fixedly connected to the first support plate, which can keep the motor's installation position stable, avoid displacement or vibration during operation, and ensure the stability of power output; the end of the worm away from the motor is movably connected to the second support plate through a bearing seat, which can limit the support of the end of the worm, keep the worm in a horizontal state when rotating, ensure the meshing accuracy of the worm and worm wheel, and improve transmission efficiency.

[0018] As a further description of the above technical solution: a protective cover is provided on the outer side of the worm and worm wheel, and the protective cover is fixedly connected to the fixing plate.

[0019] Through the above technical solution, the protective cover covers the outside of the worm and worm wheel, which can effectively block impurities and water vapor in the wastewater from entering the transmission structure, prevent impurities from adhering to the meshing surface of the worm wheel and worm, and prevent meshing jamming or component corrosion. The protective cover is fixedly connected to the fixed plate to form a closed protective space, which can also prevent operators from accidentally contacting the operating transmission components and improve the operating safety of the device.

[0020] This utility model has the following beneficial effects: This invention utilizes a synergistic design of a filtration structure and a self-cleaning structure to achieve efficient filtration of industrial wastewater while promptly removing impurities from the filter screen surface. This effectively prevents filter screen clogging, eliminates the need for frequent shutdowns for manual cleaning, ensures the continuity and stability of the device's operation, and reduces equipment maintenance costs and operational difficulty.

[0025] Reference Figure 1-5 The cleaning mechanism 7 includes two fixed plates 71, which are fixedly installed at higher positions on both sides of the inclined box 2. A rotating roller 72 is movably connected to the inner side of one of the fixed plates 71 through a bearing seat. The other end of the rotating roller 72 passes through the other fixed plate 71 and is movably connected to the fixed plate 71 through a stabilizing bearing. A brush 73 is fixedly connected to the surface of the rotating roller 72. The number of brushes 73 is several and they are evenly distributed in a ring.

[0026] Reference Figure 1-5 A worm gear 74 is fixedly connected to the surface of the rotating roller 72. A worm 75 meshes with the surface of the worm gear 74. A motor 76 is fixedly installed at one end of the worm 75. A first support plate 77 and a second support plate 78 are fixedly installed on the surface of one of the fixed plates 71.

A protective cover is provided on the outside of the worm 75 and the worm gear 74. The protective cover is fixedly connected to the fixed plate 71.

[0027] Working principle: The filter tank 1 serves as the core treatment carrier. Its internal inclined box 2 guides the industrial wastewater along an inclined path, extending the wastewater's residence time within the device. Subsequently, the motor 3 starts and drives the first rotating rod 4 to rotate. Under the combined action of the first rotating rod 4 and the second rotating rod 5, the filter screens 6 on their surfaces move accordingly, dynamically intercepting and filtering suspended impurities in the flowing wastewater. To prevent impurities from adhering and clogging the filter screen 6, the motor 76, connected to the fixed plate 71, provides power, driving the worm gear 75 to rotate. Through the meshing transmission between the worm gear 75 and the worm wheel 74 on the surface of the rotating roller 72, the rotating roller 72 rotates between the two fixed plates. Supported by the fixed plate 71, the filter operates stably. The evenly distributed brushes 73 on the rotating roller 72 rotate synchronously and contact the surface of the filter screen 6, achieving a comprehensive cleaning of the filter screen 6. The first support plate 77 and the second support plate 78 provide stable support for the motor 76 and the worm gear 75, respectively, to ensure transmission accuracy. The protective cover protects the transmission structure of the worm wheel 74 and the worm gear 75. Among them, the stabilizing bearing, bearing seat and other components further improve the operational stability of each rotating component, ensuring that the entire filtration and cleaning process is connected in an orderly manner, avoiding the interruption of subsequent sewage treatment due to the interruption of the cleaning of the filter screen 6, and improving the efficiency of sewage treatment.
