Description

Technical Field

[0001] This utility model belongs to the field of water treatment technology and relates to a river-type ecological filter bed. Background Technology

[0002] Ecological filter beds are an effective wastewater treatment method, mainly used to treat domestic sewage, industrial wastewater, etc. They remove heavy metals by adsorbing them or reacting with them to form precipitates.

[0003] Existing river-type ecological filter beds mostly have static contact with sewage. For example, patent CN217972897U discloses a river-type ecological filter bed heavy metal treatment device. The contact area between the ecological filter bed and sewage is greatly affected by the water level, making it difficult to fully utilize the filter media and resulting in poor treatment efficiency. This necessitates frequent replacements and increases maintenance costs. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a river-type ecological filter bed where the filter bed body and the wastewater are in dynamic contact, increasing the contact area between the filter bed body and the wastewater and improving the utilization rate of the filter media.

[0005] The technical solution adopted by this utility model is a river-type ecological filter bed, including a filter bed body. The filter bed body is installed in a cylindrical assembly box. The two ends of the assembly box are rotatably connected to the assembly frame through a rotating shaft. The top of the assembly frame is connected to a lifting structure, which is installed on the channel.

[0006] The lifting structure includes a bracket, which is fixedly connected to the channel. A screw is threaded onto the bracket, and a smooth rod is slidably inserted through the bracket. An assembly frame is connected to the lower end of the screw via a bearing, and the lower end of the smooth rod is fixedly connected to the assembly frame. The screw and the smooth rod are parallel.

[0007] The channel is U-shaped, and an intercepting net is fixedly connected inside the channel. A hydrodynamic structure is provided on the rotating shaft of the assembly box.

[0008] Furthermore, a pair of sealing components are provided within the channel, and the assembly box is movably connected to the pair of sealing components.

[0009] Furthermore, the sealing assembly includes a support plate, which is fixedly connected within the channel. A sealing plate is fixedly connected to one side of the support plate, and multiple springs are provided between the sealing plate and the support plate. The sealing plate is rotatably and sealingly connected to the end of the assembly box.

[0010] Furthermore, both the sealing plate and the support plate are provided with flow grooves of the same diameter as the filter bed body, and the top of both the sealing plate and the support plate is provided with through grooves for the assembly frame to pass through vertically.

[0011] Furthermore, the assembly box is provided with a filling cavity, and the filter bed body is connected to the filling cavity by bolts. Both sides of the assembly box are provided with through holes, which are connected to the filling cavity.

[0012] Furthermore, the hydrodynamic structure includes a gear transmission mechanism, which is located at the shaft end of the assembly box. The gear transmission mechanism is equipped with a transmission rod, and a blade is fixedly connected to the transmission rod.

[0013] Furthermore, a sealing box is fixedly connected to one side of the assembly frame. The sealing box is located outside the gear transmission mechanism. The rotating shaft on the assembly box is rotatably connected to the sealing box, and the transmission rod is rotatably connected to the sealing box.

[0014] Furthermore, a connecting rod is fixedly connected to one side of the assembly frame, and a pressure booster shroud is fixedly connected to one end of the connecting rod. The pressure booster shroud is arranged in an isosceles trapezoidal structure. The blade is arranged at one end of the pressure booster shroud. A support block is fixedly connected inside the pressure booster shroud. The transmission rod passes through the pressure booster shroud and is rotatably connected to the support block through a bearing.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model uses a filter bed body to filter and adsorb heavy metals in river sewage. The filter bed body can rotate within the channel, and the contact between the filter bed body and the sewage is dynamic, increasing the contact area between the filter bed body and the sewage, reducing the limitation of sewage level on the utilization rate of the filter bed body, improving the utilization rate of the filter bed body, and reducing maintenance costs. A lifting structure drives the assembly frame to adjust its height, thereby allowing the filter bed body to leave the water surface, facilitating maintenance and disassembly.

[0017] 2. By setting a sealing component, the sealing plate and the support plate are both provided with flow grooves with the same diameter as the filter bed body. The sewage flowing in the channel passes through the flow grooves and enters the filter bed body through the sealing component, making the sewage more concentrated when passing through the filter bed body.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a river-type ecological filter bed, such as Figure 1-2 As shown, the system includes a U-shaped channel 1, with an intercepting net 2 fixedly connected to its inner side. The U-shaped structure of channel 1 reduces dead zones during heavy metal treatment of wastewater. Gates can be installed on channel 1 to control the passage of wastewater. Figure 1 In the diagram, the arrow indicates the direction of sewage flow in channel 1, and the interception net 2 can intercept domestic waste in channel 1.

[0027] A lifting structure 3 is installed on channel 1. The lifting structure 3 includes a bracket 31, which is fixedly connected to the upper end of channel 1. The bracket 31 is threadedly connected to the upper end of a vertically arranged screw 32. A smooth rod 33 slides through the bracket 31 and is parallel to the screw 32. The lower end of the screw 32 is rotatably connected to an assembly frame 4 via a bearing. The lower end of the smooth rod 33 is fixedly connected to the assembly frame 4. A handwheel is provided at the end of the screw 32 away from the assembly frame 4. By rotating the handwheel, the screw 32 is driven to rotate. Under the guidance of the smooth rod 33, the screw 32 moves up and down relative to the bracket 31, thereby adjusting the height of the assembly frame 4.

[0028] In some embodiments, such as Figure 4 As shown, the assembly frame 4 is U-shaped, and a cylindrical assembly box 5 is installed inside the U-shaped opening of the assembly frame 4. The two ends of the assembly box 5 are rotatably connected to the assembly frame 4 via horizontally set pivots. A filter bed body 6 is installed inside the assembly box 5. The filter bed body 6 includes a porous resin layer and an activated carbon filter layer. The filter bed body 6 is cylindrical in shape and utilizes the properties of porous resin and activated carbon to adsorb heavy metals in the water, thus purifying the water quality. The assembly frame 4 is height-adjustable, allowing for simultaneous height changes of the filter bed body 6, thus facilitating changes in its position.

[0029] In some embodiments, the assembly box 5 is provided with a filling cavity, and the filter bed body 6 is bolted to the filling cavity. Through holes 51 are provided on both sides of the assembly box 5, and the through holes 51 communicate with the filling cavity, allowing wastewater to enter the filter bed body 6 through the through holes 51. When the filter bed body 6 needs to be replaced, the lifting structure 3 raises the assembly frame 4 to a certain height, lifting the filter bed body 6 off the water surface, facilitating maintenance and disassembly of the bolted filter bed body 6.

[0030] In some embodiments, such as Figure 2-3 As shown, a pair of sealing components 7 are installed in the channel 1, located at both ends of the assembly box 5. The assembly box 5 is movably connected to the pair of sealing components 7. Each sealing component 7 includes a support plate 71, which is fixedly connected in the channel 1. A sealing plate 72 is fixedly connected to the side of the support plate 71 near the assembly box 5. Multiple springs are provided between the sealing plate 72 and the support plate 71. The sealing plate 72 has an annular groove on the side near the assembly box 5, which is adapted to the end of the assembly box 5 to achieve a rotational sealing connection. Both the sealing plate 72 and the support plate 71 are provided with flow grooves of the same diameter as the filter bed body 6, and the top of both the sealing plate 72 and the support plate 71 is provided with through slots for the vertical passage of the assembly frame 4. The sewage flowing in the channel 1 passes through the flow grooves and the sealing components 7 into the filter bed body 6, making the sewage more concentrated when passing through the filter bed body 6. The through slots can prevent movement interference between the assembly frame 4 and the sealing components 7 when the assembly box 5 is raised and lowered.

[0031] The sealing plate 72 is made of a material with sealing properties and low coefficient of friction (such as polytetrafluoroethylene). When the assembly box 5 descends, it pushes the two sealing plates 72 closer to the support plate 71, and the spring between the sealing plate 72 and the support plate 71 is compressed. When the assembly box 5 descends to the preset position, the sealing plate 72 is rotated and sealed to the assembly box 5 under the action of the spring. When the assembly box 5 rises, it pushes the two sealing plates 72 closer to the support plate 71, and the assembly box 5 can smoothly leave the sealing plates 72 on both sides.

[0032] In some embodiments, such as Figure 5 As shown, a hydrodynamic structure 8 is provided on the rotating shaft of the assembly box 5. The hydrodynamic structure 8 includes a gear transmission mechanism 81, which is provided on the rotating shaft of the assembly box 5. A transmission rod 82 is provided on the gear transmission mechanism 81, and a blade 83 is fixedly connected to the upper end of the transmission rod 82.

[0033] In use, the sewage flowing in channel 1 drives the paddle 83, which rotates and transmits force through the transmission rod 82. This force is transmitted to the rotating shaft of the assembly box 5 by the gear transmission mechanism 81, which in turn drives the filter bed body 6 inside to rotate, so that the filter bed body 6 can come into more full contact with the sewage. When the sewage level in channel 1 is relatively lower (provided that the paddle 83 is driven by the sewage), the filter bed body 6 can also be fully utilized.

[0034] The gear transmission mechanism 81 consists of a pair of meshing cylindrical gears. One cylindrical gear is fixed on the rotating shaft of the assembly box 5, and the other gear is fixed on the transmission rod 82. In other embodiments, the gear transmission mechanism 81 can also be replaced by a belt transmission mechanism.

[0035] A sealing box 9 is fixedly connected to one side of the assembly frame 4. The rotating shaft on the assembly box 5 is rotatably connected to the sealing box 9. The transmission rod 82 is rotatably connected to the sealing box 9. The setting of the sealing box 9 can increase the waterproofness of the gear transmission mechanism 81 position, which can improve the transmission reliability. The rotatable sealing method can be achieved by using a sealed bearing.

[0036] In some embodiments, a connecting rod 10 is fixedly connected to one side of the assembly frame 4, and a pressure booster shroud 11 is fixedly connected to one end of the connecting rod 10. The pressure booster shroud 11 has an isosceles trapezoidal cross-section, and the impeller 83 is disposed at the end of the pressure booster shroud 11 with the smaller cross-section. A support block 12 is fixedly connected inside the pressure booster shroud 11, and a transmission rod 82 passes through the pressure booster shroud 11 and is rotatably connected to the support block 12 through a bearing. When sewage flows through the pressure booster shroud 11, the flow velocity of the sewage can be increased, thereby increasing the rotational speed of the impeller 83 and ensuring the effectiveness of the rotational power output.

[0037] The various embodiments in this specification are described in a related manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
