Description

Technical Field

[0001] This utility model relates to the field of aeration equipment technology, specifically an aeration device for preventing siltation and blockage in subsurface flow wetlands. Background Technology

[0002] Constructed wetlands, as an ecological wastewater treatment technology, have been widely used in domestic wastewater reuse, advanced effluent treatment, and river and lake pollution control due to their advantages such as low investment, low operating costs, good treatment effect, and simple maintenance and management. Based on the water flow pattern, constructed wetlands can be divided into surface flow wetlands and subsurface flow wetlands. Compared with surface flow wetlands, subsurface flow wetlands are less affected by climate and seasonal factors and can effectively prevent the breeding of mosquitoes and flies and the generation of odors. Disadvantages include susceptibility to clogging and insufficient oxygen supply.

[0003] Chinese patent document CN203568902U discloses a subsurface flow wetland aeration anti-clogging system, including a wetland material tank, wetland packing material filled in the wetland material tank, and a perforated pipe network set at the bottom of the wetland packing material. The wetland material tank also has a drainage false bottom. The beneficial effects of this subsurface flow wetland aeration anti-clogging system are as follows: By setting a drainage false bottom at the bottom of the wetland material tank, this system can reduce backwashing resistance, save energy, and lower costs when the wetland packing material is backwashed. The upward-moving microbubbles formed during backwashing impact the packing particles, causing deposits on the particles to fall off and pass through the drainage false bottom into the bottom of the wetland material tank for discharge, effectively preventing clogging of the wetland packing material and improving its effective porosity. Furthermore, this system has a simple structure, low cost, and is easy to maintain and manage.

[0004] The existing technologies mentioned above cannot rapidly pressurize and deliver oxygen to the subsurface flow wetland water source, resulting in low oxygen delivery efficiency. Furthermore, they cannot quickly disassemble and clean the oxygen delivery pipes, which can easily cause blockages inside the pipes. Therefore, it is necessary to develop an aeration device for preventing blockages in subsurface flow wetlands. Utility Model Content

[0005] The purpose of this invention is to provide an aeration device for preventing siltation in subsurface flow wetlands, thereby solving the problems mentioned in the background art, such as the inability of existing technologies to quickly pressurize and deliver oxygen to the water source of subsurface flow wetlands, low oxygen delivery efficiency, and the inability to quickly disassemble and clean the oxygen delivery pipes, which easily leads to siltation inside the pipes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aeration device for preventing siltation and blockage in subsurface flow wetlands, comprising an aeration operation vehicle, an aeration operation box mounted on top of the aeration operation vehicle, a threaded connector mounted on the front surface of the aeration operation box, an oxygen supply pipe sealed to the threaded connector via a universal flexible hose, an oxygen generator pump and an air supply fan respectively installed inside the aeration operation box, and a booster fan mounted on the rear surface of the aeration operation box, the booster fan and the air supply fan being used to increase the airflow pressure to deliver the oxygen generated by the oxygen generator pump into the wetland water source.

[0007] Preferably, a drive motor is installed on the outside of the aeration operation box, and the output end of the drive motor is connected to a transmission cylinder through a rotating shaft.

[0008] Preferably, one end of the transmission cylinder is connected to a drive wheel via a rotating shaft, and a driven wheel is connected to the surface of the drive wheel via a belt.

[0009] Preferably, the center of the driven wheel is connected to the air supply fan via a rotating main shaft.

[0010] Preferably, a motor operating box is installed on the outer side of the aeration operation box, and a motor assembly is installed inside the motor operating box. The output end of the motor assembly is connected to the booster fan via a rotating shaft.

[0011] Preferably, the threaded connector and the universal hose are detachable, and one end of the universal hose is tightly screwed and fixed to the threaded connector via a threaded joint.

[0012] Preferably, the bottom of the aeration vehicle is equipped with a drive track, and the drive track has a movable wheel installed inside.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a pressurized blower system that boosts airflow within the aeration chamber, allowing oxygen generated by the oxygen generator pump to be quickly and safely delivered to the water source within the subsurface flow wetland. This facilitates oxygenation of the wetland water source by exposing it to air, accelerating the transfer of oxygen from the air into the liquid. The oxygen delivery pipe is designed to be detachable, making it easy to clean its interior regularly and preventing blockages when inserted into the subsurface flow wetland.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1-4 An embodiment of this utility model provides an aeration device for preventing siltation and clogging of subsurface flow wetlands, comprising an aeration operation vehicle 8, an aeration operation box 3 mounted on top of the aeration operation vehicle 8, a threaded connector 4 mounted on the front surface of the aeration operation box 3, an oxygen supply pipe 7 sealed to the threaded connector 4 via a universal hose 6, an oxygen generator pump 14 and an air supply fan 15 mounted inside the aeration operation box 3, and a booster fan 10 mounted on the rear surface of the aeration operation box 3. The booster fan 10 and the air supply fan 15 are used to increase the airflow pressure to deliver the oxygen generated by the oxygen generator pump 14 into the wetland water source.

[0022] Furthermore, a drive motor 2 is installed on the outside of the aeration operation box 3. The output end of the drive motor 2 is connected to the transmission cylinder 5 through a rotating shaft. The drive motor 2 is turned on to drive and control the rotation of the transmission cylinder 5.

[0023] Furthermore, one end of the transmission cylinder 5 is connected to a drive wheel 11 via a rotating shaft. The surface of the drive wheel 11 is connected to a driven wheel 13 via a belt 12. The center of the surface of the driven wheel 13 is connected to the air supply fan 15 via a rotating main shaft 16. The rotation of the transmission cylinder 5 drives the drive wheel 11 to rotate synchronously. Under the action of the belt 12, the driven wheel 13 is driven to rotate, which can further drive the air supply fan 15 to run at high speed. This facilitates the rapid and safe delivery of oxygen generated by the oxygen generator pump 14 to the water source inside the subsurface flow wetland, promoting contact between the wetland water source and the air for oxygenation and accelerating the transfer of oxygen from the air to the liquid.

[0024] Furthermore, a motor operating box 1 is installed on the outer side of the aeration operation box 3. A motor assembly is installed inside the motor operating box 1. The output end of the motor assembly is connected to the booster fan 10 through a rotating shaft. By turning on the motor assembly, the booster fan 10 can be quickly driven and controlled to operate, which can be used to increase the gas flow speed inside the aeration operation box 3.

[0025] Furthermore, the threaded connector 4 and the universal hose 6 are detachable. One end of the universal hose 6 is tightly screwed to the threaded connector 4 through a threaded joint, which has the advantages of convenient and quick installation and disassembly. By adopting a detachable design for the oxygen pipeline 7, it is easy to clean its interior regularly and prevent it from being inserted into the subsurface wetland and causing siltation.

[0026] Furthermore, the bottom of the aeration vehicle 8 is equipped with a drive track 9, and the drive track 9 has movable wheels installed inside, which facilitates flexible movement on the surface of the subsurface flow wetland and improves the mobility of the aeration vehicle 8.

[0027] Working principle: During use, an aeration box 3 is installed on top of the aeration vehicle 8. Inside the aeration box 3, an oxygen generator pump 14 and an air delivery fan 15 are installed. A booster fan 10 is installed on the rear surface of the aeration box 3. By turning on the oxygen generator pump 14, a large amount of oxygen is generated inside the aeration box 3. The motor assembly is then turned on to quickly drive the booster fan 10, increasing the gas flow rate inside the aeration box 3. Subsequently, the drive motor 2 is turned on to drive the transmission cylinder 5 to rotate. The rotation of the transmission cylinder 5 drives the drive wheel 11 to rotate synchronously. Under the action of the belt 12... The driven wheel 13 is rotated, which in turn drives the air supply fan 15 to run at high speed, so as to quickly and safely blow the oxygen generated by the oxygen generator pump 14 into the water source inside the subsurface flow wetland, so as to promote the contact between the wetland water source and the air to oxygenate, and accelerate the transfer of oxygen in the air into the liquid. The front surface of the aeration operation box 3 is equipped with a threaded pipe 4. The threaded pipe 4 is sealed to the oxygen supply pipe 7 through the universal hose 6. One end of the universal hose 6 is tightly screwed to the threaded pipe 4 through the threaded joint. The oxygen supply pipe 7 adopts a detachable design, which facilitates the regular cleaning of its interior and prevents it from being inserted into the subsurface flow wetland and causing siltation.
