Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device with a filtration structure. Background Technology

[0002] Wastewater treatment refers to the key environmental protection process of physically, chemically, or biologically purifying pollutants in wastewater generated from industrial production, domestic discharge, or commercial activities to meet discharge standards or reuse requirements. Filtration, as the core of physical treatment, is mainly used to remove suspended particles, silt, fibers, oil, and other insoluble impurities from the water. It directly affects the clarity of the effluent and plays a decisive role in the stable operation of subsequent biological treatment units (such as activated sludge processes and membrane bioreactors). If the front-end filtration is insufficient, a large amount of impurities will enter the subsequent system, leading to clogging of the filter media, scaling of aeration heads, increased membrane fouling, and even equipment damage, significantly increasing operation and maintenance costs and energy consumption.

[0003] Existing wastewater treatment equipment uses a single filter screen or fixed filter plate for coarse filtration, which can only intercept larger particles and has little effect on removing fine suspended solids, colloids, or fibrous impurities. This directly leads to a decrease in the overall efficiency of the wastewater treatment system, an increase in the complexity of operation and management, and makes it difficult to meet the specific requirements of modern environmental protection projects for efficient pretreatment, continuous and stable operation, and intelligent operation and maintenance. Therefore, in view of the problems of simple filtration structure and insufficient interception efficiency in existing technologies, we urgently need a wastewater treatment device with a filtration structure. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment device with a filtration structure, which solves the problem that existing wastewater treatment equipment uses a single filter screen or fixed filter plate for coarse filtration, which can only intercept larger particles and has little effect on removing fine suspended solids, colloids or fibrous impurities, directly leading to a reduction in the overall efficiency of the wastewater treatment system.

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

[0006] A wastewater treatment device with a filtration structure includes a wastewater treatment tank. A filter plate is slidably connected to the lower inner side of the wastewater treatment tank, and a top cover is detachably connected to the top of the wastewater treatment tank. A drive motor is fixedly connected to one side of the top of the top cover by bolts. A bearing plate is provided on the top of the filter plate, and a rotating rod is fixedly connected to the top of the bearing plate. The top end of the rotating rod passes through the top cover and is connected to the output shaft of the drive motor via a bearing sleeve. Several adsorption rods are fixedly connected to the top of the bearing plate, and all the adsorption rods are arranged in a circular array along the bearing plate. Aeration pipes are provided on both sides of the bottom of the filter plate, and one side of each of the two aeration pipes is fixedly connected to the inner wall of the wastewater treatment tank. An air pump is fixedly connected to one side of the outer wall of the wastewater treatment tank by bolts, and one end of each of the two aeration pipes is connected to the outlet of the air pump. Water inlet frames are connected to both sides of the top of the top cover.

[0007] Preferably, sliders are fixedly connected to both sides of the filter plate, and both sliders are slidably connected to the inner wall of the wastewater treatment tank through a sliding groove.

[0008] Preferably, an inspection door is hinged to the upper side of the wastewater treatment tank, and a bottom valve is installed on the lower side of the wastewater treatment tank.

[0009] Preferably, each of the four corners at the top of the wastewater treatment tank is fixedly connected to an installation frame, and each of the four installation frames has an insert plate on its inner side and an insert rod on one side of each of the four installation frames, with one end of the insert rod passing through one side of the installation frame and the insert plate in sequence.

[0010] Preferably, a connecting pipe is provided on one side of the wastewater treatment tank, and both ends of the connecting pipe penetrate the side wall of the wastewater treatment tank. The two ends of the connecting pipe are respectively connected to one end of two aeration pipes, and one end of the connecting pipe is connected to the outlet of the air pump.

[0011] Preferably, connecting plates are fixedly connected to both sides of the top of the filter plate, and handles are provided on both sides of the top of the filter plate, with the two ends of the two handles fixedly connected to the top of the two connecting plates respectively.

[0012] This utility model has at least the following beneficial effects:

[0013] In this invention, the adsorption rod rotates continuously under the drive of a motor, significantly increasing the contact frequency and contact area with pollutants. This dramatically improves the capture efficiency of fine suspended solids, colloids, and oily substances that are difficult to remove with traditional filters. The air bubbles released by the aeration pipe not only agitate the water flow to prevent sedimentation but also lift light pollutants to the adsorption area through flotation. The filter plate, as the final barrier, effectively intercepts large particulate impurities, protecting subsequent treatment units. The combination of rotary adsorption and aeration avoids the problem of rapid clogging of a single filter layer, extending the operating cycle. Both the top cover and the filter plate adopt a detachable or sliding connection design, allowing the adsorption components and filter plates to be quickly removed for cleaning or replacement, greatly reducing maintenance difficulty and labor costs. This achieves gradient purification from coarse filtration to fine adsorption, effectively solving the problem that existing wastewater treatment equipment uses a single filter or fixed filter plate for coarse filtration, which can only intercept larger particles and has little effect on removing fine suspended solids, colloids, or fibrous impurities, directly leading to a reduction in the overall efficiency of the wastewater treatment system.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figures 1-6 A wastewater treatment device with a filtration structure includes a wastewater treatment tank 1. A filter plate 11 is slidably connected to the lower inner side of the wastewater treatment tank 1, and a top cover 2 is detachably connected to the top of the wastewater treatment tank 1. A drive motor 9 is fixedly connected to one side of the top of the top cover 2 by bolts. A bearing filter plate 12 is provided on the top of the filter plate 11, and a rotating rod 10 is fixedly connected to the top of the bearing filter plate 12. The top end of the rotating rod 10 passes through the top cover 2 through a bearing sleeve and is connected to the output shaft of the drive motor 9. Several adsorption rods 13 are fixedly connected to the top of the bearing filter plate 12, and all the adsorption rods 13 are arranged in a ring array along the bearing filter plate 12. Aeration pipes 16 are provided on both sides of the bottom of the filter plate 11, and one side of each of the two aeration pipes 16 is fixedly connected to the inner wall of the wastewater treatment tank 1. An air pump 17 is fixedly connected to one side of the outer wall of the wastewater treatment tank 1 by bolts, and one end of each of the two aeration pipes 16 is connected to the outlet of the air pump 17. Water inlet frames 8 are connected to both sides of the top of the top cover 2.

[0024] First, the wastewater to be treated is injected into the wastewater treatment tank 1 through the inlet frames 8 connected to both sides of the top of the top cover 2. Then, two key functional units are activated simultaneously: On the one hand, the air pump 17, which is bolted to one side of the outer wall of the wastewater treatment tank 1, is turned on. Its output gas is transported through pipelines to the aeration pipes 16 fixed to both sides of the bottom of the wastewater treatment tank 1. The gas is evenly released from the aeration pipes 16 to form a large number of microbubbles, which causes strong disturbance and turbulence in the wastewater in the tank. This not only promotes the removal of suspended solids from the settling state, but also increases the probability of contact between impurities and subsequent adsorption media. On the other hand, the drive motor 9, which is bolted to one side of the top of the top cover 2, is started. Its output shaft passes through the top cover 2 through a bearing sleeve and is connected to the top of the rotating rod 10. This drives the rotating rod 10 and the bearing filter plate 12 fixed to it to rotate at a constant speed. The several adsorption rods 13 distributed in a ring array on the top of the bearing filter plate 12 rotate synchronously, continuously agitating the water flow and efficiently capturing fine suspended particles, colloids, and oil in the water by utilizing their own surface properties during the rotation. Lipid and fibrous pollutants; simultaneously, wastewater seeps downwards under gravity, and the water flow after rotational adsorption continues to pass through the filter plate 11, which is slidably connected to the lower inner side of the wastewater treatment tank 1. The filter plate 11 intercepts larger particulate impurities, achieving physical interception; throughout the operation, the rising airflow generated by aeration and the rotational motion of the adsorption rod 13 form a synergistic effect. Bubbles attach to hydrophobic impurities, causing them to float and be captured by the adsorption rod 13, while the sinking particles are effectively intercepted by the filter plate 11, thus constructing a composite purification mechanism of dynamic adsorption, static filtration, and flotation assistance; when maintenance is required after a period of operation, the machine can be stopped and the wastewater drained first, and then the top cover 2 can be removed from the top of the wastewater treatment tank 1, and the entire assembly of drive motor 9, rotating rod 10, bearing filter plate 12, and adsorption rod 13 can be taken out together for cleaning or replacement of adsorption materials; then the slidably connected filter plate 11 can be pulled out from the wastewater treatment tank 1 for rinsing or replacement; the entire maintenance process does not require special tools, is easy to operate, and significantly shortens downtime.

[0025] Furthermore, sliders 18 are fixedly connected to both sides of the filter plate 11, and both sliders 18 are slidably connected to the inner wall of the wastewater treatment tank 1 through the slide groove 19. During maintenance, the filter plate 11 is vertically pulled out or pushed in along the slide groove 19. This achieves the effect of ensuring that the filter plate 11 is installed and disassembled smoothly and accurately, avoiding jamming or tilting, and improving replacement efficiency.

[0026] Furthermore, an inspection door 6 is connected to the upper side of the wastewater treatment tank 1 via a hinge, and a bottom valve 7 is installed on the lower side of the wastewater treatment tank 1. During daily operation, the bottom valve 7 is used to drain the treated wastewater in the wastewater treatment tank 1. During maintenance, the inspection door 6 can be opened to observe the internal structure or perform partial cleaning, providing an additional maintenance channel, facilitating emergency handling or auxiliary cleaning, reducing the frequency of complete disassembly, and improving operational flexibility.

[0027] Furthermore, each of the four corners of the upper part of the wastewater treatment tank 1 is fixedly connected to an installation frame 3, and each of the four installation frames 3 has an insert plate 4 on its inner side, and each of the four installation frames 3 has an insert rod 5 on one side. One end of the insert rod 5 passes through one side of the installation frame 3 and the insert plate 4 in sequence. When installing the top cover 2, insert the insert plate 4 into the installation frame 3, and then insert the insert rod 5 to lock it. When disassembling, the top cover 2 can be removed by pulling out the insert rod 5, which realizes the effect of quick installation and removal of the top cover 2, reliable sealing, no need for bolts and tools, and ensures the centering accuracy of the rotating parts.

[0028] Furthermore, a connecting pipe 20 is provided on one side of the wastewater treatment tank 1, and both ends of the connecting pipe 20 penetrate the side wall of the wastewater treatment tank 1. Both ends of the connecting pipe 20 are connected to one end of the two aeration pipes 16 respectively, and one end of the connecting pipe 20 is connected to the outlet of the air pump 17.

[0029] Furthermore, connecting plates 14 are fixedly connected to both sides of the top of the filter plate 11, and handles 15 are provided on both sides of the top of the filter plate 11. The two ends of the two handles 15 are fixedly connected to the top of the two connecting plates 14 respectively. The operator can easily pull the filter plate 11 by holding the handles 15, providing a labor-saving, non-slip, and easy-to-apply operating structure, which significantly improves the ease of disassembly and assembly and the safety of maintenance of the filter plate 11.

[0030] In summary:

[0031] First, the wastewater to be treated is injected into the wastewater treatment tank 1 through the inlet frames 8 connected to both sides of the top of the top cover 2. Then, the air pump 17, which is bolted to one side of the outer wall of the wastewater treatment tank 1, is started. The output gas is evenly distributed to the aeration pipes 16 fixed on both sides of the bottom through the connecting pipe 20. The gas is released from the aeration pipes 16 to form a large number of microbubbles, which fully agitates and churns the wastewater in the tank, promotes the removal of suspended solids from the settling state and enhances the contact with the adsorption medium. At the same time, the drive motor 9, which is bolted to one side of the top of the top cover 2, is started. Its output shaft passes through the top cover 2 through the bearing sleeve and is connected to the top of the rotating rod 10, which drives the bearing plate 12 and several adsorption rods 13 arranged in a ring array. The system rotates at a constant speed, continuously agitating the water flow and efficiently capturing fine suspended particles, colloids, oils, and fibrous pollutants during the dynamic process. Wastewater permeates downwards under gravity, and the adsorption-treated water flows through the filter plate 11 located at the lower inner side of the wastewater treatment tank 1. The filter plate 11 traps larger particles, achieving physical interception. During this process, the rising airflow generated by aeration and the rotating adsorption rod 13 create a synergistic effect; hydrophobic impurities attach to bubbles and float to the surface, where they are captured by the adsorption rod 13, while heavy particles sink and are intercepted by the filter plate 11, constructing a composite purification mechanism of dynamic adsorption, static filtration, and flotation assistance. When maintenance is required after a period of operation, first open the lower part of the wastewater treatment tank 1... The side-mounted bottom valve 7 drains the residual wastewater. Then, pull out the four insert rods 5 on the four mounting frames 3, and disassemble the top cover 2 along with the drive motor 9, rotating rod 10, bearing filter plate 12, and adsorption rod 13. Next, grasp the handles 15 fixed to the top of the filter plate 11 on both sides by the connecting plate 14, and vertically pull out the filter plate 11 along the slide groove 19 for cleaning or replacement. If only partial inspection or cleaning is required, the maintenance door 6 connected by hinges can be opened without completely disassembling the top cover 2. After maintenance, push the filter plate 11 back to its original position, reinstall the top cover 2 and insert the insert rods 5 to lock it, close the maintenance door 6 and bottom valve 7, and it can be put back into operation. The entire process is simple to operate, requires no special tools, and significantly shortens the time required. During downtime, the adsorption rod 13 continuously updates its surface contact area while rotating, significantly improving its ability to capture fine pollutants that are difficult to remove with traditional filters; the aeration pipe 16 achieves balanced air supply from both sides through the connecting pipe 20, ensuring uniform flotation effect; the filter plate 11, together with the slider 18 and the slide groove 19, achieves precise guidance, avoiding installation misalignment, and the handle 15 provides labor-saving operation; the top cover 2 is quickly locked to the insert plate 4 through the insert rod 5, ensuring that the rotating parts are aligned and reliably sealed; the maintenance door 6 and the bottom valve 7 provide flexible drainage and partial maintenance channels, reducing the frequency of full disassembly; the whole machine organically combines flotation, dynamic adsorption and static filtration, effectively solving the problem of poor effect of single filtration methods in existing technologies.
