Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a blower pipe component and a wastewater treatment system. Background Technology

[0002] In the aeration system of biological treatment tanks in wastewater treatment, blowers typically need to provide a constant airflow to meet the oxygen requirements of microorganisms. However, during actual operation, due to fluctuations in water quality, changes in load, or process adjustments, the system often experiences a momentary decrease in airflow demand, resulting in some airflow becoming "surplus airflow" (i.e., airflow exceeding actual demand). Currently, existing technologies lack effective mechanisms for utilizing surplus airflow, leading to increased overall system power consumption, which is inconsistent with the current energy-saving and consumption-reducing development trend in the wastewater treatment industry. Furthermore, the industry's common practice of directly venting excess air into the atmosphere through pressure relief valves to handle surplus airflow also results in significant energy waste. Utility Model Content

[0026] like Figures 1-4 As shown, a blower duct component in one embodiment of the present invention includes a connecting device and an exhaust duct 4. The connecting device includes a flow component 1, a mounting bracket 2, and an extension duct 3. The flow component 1 is fixed on the mounting bracket 2. An air inlet and an air outlet are respectively provided at both ends of the flow component 1. The air inlet is detachably connected to the extension duct 3. The exhaust duct 4 is connected to the outside of the extension duct 3. A first exhaust fan is provided inside the exhaust duct 4. The first exhaust fan includes an exhaust fan 5 and a drive component 6 for controlling the rotation of the exhaust fan 5. A heat dissipation cavity 611 is formed inside the drive component 6. A heat dissipation fin 612 is provided on one side of the inner wall of the heat dissipation cavity 611.

[0027] The aforementioned blower duct components, with the mounting bracket 2, can support the connecting device and prevent the duct from deforming and being damaged by external forces (such as gravity, temperature changes, etc.); with the flow assembly 1, the air inlet and outlet on the flow assembly 1 facilitate the flow of excess air between the biological tank and the sedimentation tank, thereby treating the surplus air volume and avoiding energy waste; with the first exhaust fan, the air volume is quickly drawn into the flow assembly 1 by forcing air flow through the negative pressure principle; with the heat dissipation fins 612, the heat generated by the drive component 6 can be dissipated, which helps to increase the service life of the drive component 6.

[0028] like Figure 1 and Figure 2 As shown, in one embodiment, the circulation component 1 includes a second exhaust fan, a first connecting pipe 11 and a second connecting pipe 12. The bottom of the second exhaust fan is fixed on the mounting bracket 2. The first connecting pipe 11 and the second connecting pipe 12 are detachably connected to the two ends of the second exhaust fan, respectively. The air inlet is provided on the first connecting pipe 11 and the air outlet is provided on the second connecting pipe 12.

[0029] like Figure 1 and Figure 2As shown, in one embodiment, an air inlet valve 111 is provided on the air inlet and sleeved on one end of the extension pipe 3. An air outlet valve 121 is sleeved on the air outlet and has a first control handle 122. By providing the air inlet valve 111 and the air outlet valve 121, the air flow through the pipe can be adjusted by changing the opening degree of the valves, thereby meeting the ventilation requirements of the surplus air volume.

[0030] like Figure 2 As shown, in one embodiment, a side interface 33 is provided on the outer wall of the extension pipe 3, and the exhaust pipe 4 is connected to the side interface 33. The air intake direction can be flexibly adjusted as needed to adapt to the configuration of different sewage treatment systems.

[0031] like Figure 2 As shown, in one embodiment, a connecting valve 31 is fitted on the other end of the extension pipe 3 away from the air inlet valve 111, and a second control handle 32 is provided on the connecting valve 31.

[0032] like Figure 3 and Figure 4 As shown, in one embodiment, the drive unit 6 includes a housing 61, a rotating shaft 62, and an inner fan blade 63. The exhaust fan 5 is sleeved on one end of the rotating shaft 62. A heat dissipation cavity 611 is formed inside the housing 61. A tail cover 64 is provided on the housing 61. The rotating shaft 62 passes through the heat dissipation cavity 611 and extends into the tail cover 64. The inner fan blade 63 is located inside the tail cover 64 and sleeved on the other end of the rotating shaft 62. A filter screen 641 is provided on one side of the inner wall of the tail cover 64. When the drive unit 6 is working, the rotating shaft 62 will cause the inner fan blades 63 to rotate during the rotation process. The inner fan blades 63 can draw in the external cold air and enter the interior of the drive unit 6 through the air inlet 642 on the tail cover 64. The filter screen 641 can block the dust in the airflow. The heat dissipation fins 612 on the heat dissipation cavity 611 can dissipate the heat generated by the drive unit 6 during operation. The cold air drawn into the interior of the drive unit 6 by the inner fan blades 63 can effectively cool the heat dissipation fins 612, making the heat dissipation effect of the drive unit 6 better.

[0033] like Figure 4 As shown, in one embodiment, heat dissipation holes 613 are provided at the bottom and top of the inner wall of the heat dissipation cavity 611; and an air inlet 642 is provided on one side of the inner wall of the tail cover 64.

[0034] In one embodiment, one end of the exhaust duct 4 is snapped onto the side interface 33 by a sealing ring, and the other end of the exhaust duct 4 is threaded with an adjusting pipe 7. A sealing ring is coaxially arranged on the inner wall of the sealing ring, and the two ends of the sealing ring are used to abut against the side interface 33 and the exhaust duct 4, respectively. This reduces the deformation of the sealing ring during installation, reduces damage caused by compression, and makes installation easier. Since both ends abut against the sealing ring, the sealing ring can seal the connection between the side interface 33 and the exhaust duct 4.

[0035] like Figure 5 As shown, in one embodiment, the regulating pipe 7 includes a fixing head 71, an regulating hose 72, and a connecting head 73. The fixing head 71 is threaded onto the exhaust pipe 4 and is sleeved on one end of the regulating pipe 7. The other end of the regulating pipe 7 is detachably connected to the connecting head 73. Thus, the regulating hose 72 is adjustable, allowing for length and orientation adjustments as needed, making it suitable for various complex environments and application scenarios. The connecting head 73 facilitates the installation and fixing of the regulating hose 72, making it easy to connect to surplus airflow outlets at different locations.

[0036] Preferably, the adjusting hose 72 is a plastic hose. It is wear-resistant and corrosion-resistant, and is inexpensive and easy to maintain.

[0037] A wastewater treatment system includes a blower duct component, a biological treatment tank, and a grit chamber. A first air inlet duct is provided on the outer side of one end of the biological treatment tank, and a blower is fixedly connected to the first air inlet duct and connected to the output end of the blower. An air outlet duct is provided on the outer side of the other end of the biological treatment tank, and a second air inlet duct is provided on the grit chamber. The blower duct component is connected between the air outlet duct and the second air inlet duct.

[0038] The aforementioned wastewater treatment system can transfer the surplus air volume of the biological aeration system to the grit removal system through the blower duct component. After the modification, the original blower of the grit removal system is decommissioned. While ensuring the smooth operation of the grit removal system, the system can efficiently utilize the surplus air volume of the biological aeration system, achieve energy-saving operation, and reduce operating costs.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
