Description

Technical Field

[0001] This utility model relates to the field of filler ecological wetland technology, specifically a filler ecological wetland for water purification. Background Technology

[0002] Filler-based ecological wetlands are artificial ecosystems that simulate the functions of natural wetlands. They achieve water purification through the synergistic effects of fillers, plants, and microorganisms. The core of these wetlands is to utilize the physical filtration, chemical adsorption, and biodegradation capabilities of fillers, combined with plant absorption and microbial metabolism, to efficiently remove pollutants from the water.

[0003] However, traditional pretreatment relies solely on simple screens or short-retention-time grit chambers, which cannot effectively remove fine particulate matter and colloidal substances. As a result, after long-term use, the porosity of the packing layer gradually decreases, the hydraulic conductivity decreases, and physical blockage occurs, affecting the water purification effect of the packing ecological wetland. Therefore, we propose a packing ecological wetland for water purification. Utility Model Content

[0004] The purpose of this invention is to provide a filler ecological wetland for water purification, in order to solve the problem mentioned in the background art that traditional pretreatment relies only on simple screens or short-retention-time grit chambers, which cannot effectively remove fine particulate matter and colloidal substances. As a result, after long-term use, the porosity of the filler layer gradually decreases, the hydraulic conductivity decreases, and physical blockage occurs, thus affecting the water purification effect of the filler ecological wetland.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filler ecological wetland for water purification, comprising a box body, a support frame fixedly installed on the top of the box body, a filler layer disposed inside the support frame, a water inlet fixedly installed inside one side of the support frame, a water outlet fixedly installed inside the other side of the support frame, a backwashing assembly disposed inside the box body, and two vibration assemblies disposed inside the filler layer.

[0006] The backwashing assembly includes a water pump, which is fixedly installed inside the housing. A water pump is fixedly installed at one end of the water pump, and a water valve is fixedly installed at the other end of the water pump.

[0007] The water valve is fixedly installed on one side of the housing, the top of the water pump is fixedly installed with a spray pipe, and the outside of the spray pipe is fixedly installed with a nozzle.

[0008] The nozzle has a filter screen fixedly installed inside, the nozzle penetrates the bottom of the support frame, and the outside of the nozzle is in contact with the filler layer.

[0009] The vibration assembly includes a waterproof cover, which is fixedly installed on one side of the support frame. A motor is fixedly installed inside the waterproof cover, and a rotating rod is fixedly installed at one end of the motor's output shaft.

[0010] The vibrating rod is fixedly installed on the inner wall of the support frame. The vibrating rod penetrates the packing layer. A rotating rod is rotatably connected inside the vibrating rod, and an eccentric block is fixedly installed outside the rotating rod.

[0011] This utility model has at least the following beneficial effects:

[0012] The backwashing component uses a water pump to pressurize water into a high-pressure flow, which is then evenly flushed through the spray pipes and nozzles to wash the surface and gaps of the packing layer. This effectively removes accumulated pollutants, and the water flow carries the pollutants out of the outlet, restoring the permeability and adsorption capacity of the packing layer and preventing a decrease in purification efficiency due to increased resistance. In the vibration component, the motor drives the eccentric block to rotate, generating centrifugal force. This causes the vibrating rod to transmit vibration to the packing layer, loosening the gaps between the packing and breaking the adhesion structure between pollutants and the packing surface. Combined with the backwashing water flow, this can more thoroughly flush away pollutants and reduce residue. Attached Figure Description

[0018] 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.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: a filler ecological wetland for water purification, including a box 3, a support frame 1 fixedly installed on the top of the box 3, a filler layer 5 inside the support frame 1, a water inlet 4 fixedly installed on one side of the support frame 1, a water outlet 6 fixedly installed on the other side of the support frame 1, a backwashing component 7 inside the box 3, and two vibration components 2 inside the filler layer 5.

[0020] The backwash assembly 7 includes a water pump 71, which is fixedly installed inside the housing 3. A water suction pipe 72 is fixedly installed at one end of the water pump 71, and a water valve 73 is fixedly installed at the other end of the water suction pipe 72. The water valve 73 is fixedly installed on one side of the housing 3. A spray pipe 74 is fixedly installed on the top of the water pump 71, and a spray head 75 is fixedly installed on the outside of the spray pipe 74. A filter screen 76 is fixedly installed inside the spray head 75, and the spray head 75 penetrates the bottom of the support frame 1. The outside of 5 is in contact with the packing layer 5. When it is necessary to clean the packing layer 5, the water pump 71 in the box 3 is started, the water valve 73 is opened, and the water pumping pipe 72 draws water from the outside or the water storage in the box 3. After the water is pressurized by the water pump 71, it enters the spray pipe 74 and is sprayed upward into the inside of the packing layer 5 through the nozzle 75. The filter screen 76 in the nozzle 75 can filter impurities in the backwash water to prevent the nozzle 75 from being blocked. The spray water flow performs reverse flushing on the packing layer 5 and removes the pollutants adsorbed on the surface of the packing.

[0021] The vibration assembly 2 includes a waterproof cover 21, which is fixedly installed on one side of the support frame 1. A motor 22 is fixedly installed inside the waterproof cover 21. A rotating rod 24 is fixedly installed at one end of the output shaft of the motor 22. A vibrating rod 25 is fixedly installed on the inner wall of the support frame 1. The vibrating rod 25 penetrates the packing layer 5. The rotating rod 24 is rotatably connected inside the vibrating rod 25. An eccentric block 23 is fixedly installed outside the rotating rod 24. After the motor 22 of the vibration assembly 2 is started, it drives the rotating rod 24 to rotate. The eccentric block 23 on the rotating rod 24 rotates accordingly, generating centrifugal force to drive the vibrating rod 25 to vibrate at high frequency. The vibrating rod 25 penetrates the packing layer 5 and transmits the vibration to the inside of the packing, causing the packing particles to vibrate and loosen. Combined with the backwash water flow, it can more efficiently remove the blockage in the gaps of the packing, prevent the packing from caking, and maintain its water permeability and air permeability.

[0022] After a period of use, the packing layer 5 may accumulate a lot of contaminants on its surface, leading to increased water flow resistance and decreased purification efficiency. At this time, the backwashing assembly 7 needs to be activated to clean the packing layer 5. First, the water valve 73 is opened, and the water pump 71 inside the housing 3 starts working. The water pump 71 draws water from the outside through the suction pipe 72. After being pressurized by the water pump 71, the water flows into the top spray pipe 74. The spray pipe 74 is mesh-like or has multiple branches, which can evenly distribute the water flow to each nozzle 75. The nozzle 75 penetrates the bottom of the support frame 1, and its exterior contacts the packing layer 5. A filter screen 76 is installed inside the nozzle 75. The function of the filter screen 76 is to filter out larger impurities in the water, preventing these impurities from clogging the nozzle 75 and ensuring smooth water flow from the nozzle 75. The water flow filtered by the filter screen 76 is sprayed out from the nozzle 75, spraying onto the packing layer 5 at a certain pressure and angle, rinsing the surface of the packing and washing away the contaminants accumulated on the surface and in the gaps of the packing. The pollutants washed down are carried by the water flow through the filler layer 5 and finally discharged from the wetland system through the outlet 6, thereby cleaning the filler layer 5 and restoring its purification capacity.

[0023] After the motor 22 is powered on, the output shaft drives the rotating rod 24 to rotate. The eccentric block 23 on the rod, due to its center of gravity deviating from the center of rotation, generates centrifugal force, causing the rotating rod 24 to drive the vibrating rod 25 to vibrate. The vibrating rod 25 penetrates the packing layer 5 and is rotatably connected to the rotating rod 24, so the vibration of the vibrating rod 25 is transmitted to the entire packing layer 5. The packing material within the packing layer 5 vibrates slightly under the action of the vibrating rod 25. This vibration effectively loosens the gaps between the packing materials, making it easier for contaminants adhering to the surface and gaps of the packing material to be flushed away by the backwash water flow, thus improving the efficiency and effectiveness of backwashing. Furthermore, during normal purification, periodically activating the vibration assembly 2 can prevent the packing layer 5 from becoming caked or clogged due to long-term use, maintaining the good permeability and purification capacity of the packing layer 5.
