Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment, and in particular to an aeration blower for a sewage nitrification tank. Background Technology

[0002] In wastewater treatment processes, the nitrification tank is the core component of biological nitrogen removal, and its operational efficiency directly affects the removal efficiency of pollutants such as ammonia nitrogen in wastewater. As a key supporting facility for the nitrification tank, the aeration blower continuously supplies air into the tank, providing sufficient oxygen for nitrifying bacteria and other microorganisms to maintain their metabolic activity and ensure efficient nitrification. Therefore, the stable operation of the aeration blower is an important prerequisite for ensuring that the wastewater treatment system meets discharge standards. Currently, the aeration blower equipment commonly used in sewage nitrification tanks generates a lot of heat in its core components such as motors and impellers during operation due to mechanical friction and energy conversion. If the heat cannot be dissipated in time, the internal temperature of the equipment will continue to rise, which will not only reduce the working efficiency of the blower, but may also cause problems such as motor overload, insulation aging, and accelerated bearing wear. In severe cases, it may even cause the equipment to shut down, affecting the normal operation of the nitrification tank and increasing the cost of sewage treatment. To address the heat dissipation issue, existing aeration blowers generally employ a louvered structure for natural ventilation. However, most louvers in existing equipment are fixed in design, and the tilt angle of the blades and the size of the ventilation channel openings cannot be adjusted. When the blower operates under low load, less heat is generated internally, and the fixed openings may allow excessive cold air to enter, especially in low ambient temperatures, potentially affecting internal components due to sudden temperature changes. Conversely, when the blower operates under high load or in high ambient temperatures, the internal temperature rises rapidly, and the fixed opening size cannot meet the heat dissipation requirements, making it difficult for heat to escape quickly and resulting in a high-temperature environment inside the equipment. Prolonged operation under these conditions accelerates the aging of internal components such as motors and wiring, shortens the equipment's lifespan, increases the failure rate and maintenance frequency, and adversely affects the stable operation of wastewater treatment plants.

[0003] Therefore, it is necessary to provide a new aeration blower device for wastewater nitrification tanks to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an aeration blower device for a sewage nitrification tank.

[0005] The wastewater nitrification tank aeration blower equipment provided by this utility model includes: equipment body, louvers, adjustment components and filter elements. The blower body is installed inside the equipment body and the air outlet pipe is installed on the top. Louvers for heat dissipation are installed at equal intervals on both sides of the equipment body. An adjustment component is installed between the louvers and the equipment body. The adjustment component drives the louvers to rotate to adjust their opening angle for heat dissipation. A filter element for filtering impurities is installed on the side wall of the equipment body.

[0006] Preferably, the adjustment assembly includes: an electric push rod, a crossbar, and a rack. The electric push rod is fixedly connected to the side wall of the equipment body. The output end of the electric push rod is fixedly connected to the crossbar. Both ends of the crossbar are fixedly connected to racks. The inside of each louver is fixedly connected to a connecting rod. The end of the connecting rod near the rack extends out of the equipment body and is fixedly connected to a gear, and each gear meshes with the corresponding rack.

[0007] Preferably, a temperature sensor is fixedly connected to the inner wall of the device body.

[0008] Preferably, the input end of the fan body is fixedly connected to the side wall of the equipment body through an air inlet pipe, and a mounting bracket is fixedly connected to the side wall of the equipment body near the air inlet pipe, and the filter element is installed inside the mounting bracket.

[0011] Compared with related technologies, the aeration blower equipment for wastewater nitrification tanks provided by this utility model has the following beneficial effects: By adjusting the design of components and temperature sensors, dynamic regulation of the internal temperature of the equipment can be achieved. This dynamic regulation method can accurately control the heat dissipation according to the actual heat generation of the equipment, avoiding the problem of insufficient or excessive heat dissipation of fixed openings under different operating conditions. This extends the service life of internal components such as motors and circuits, reduces the failure rate and maintenance frequency, and the heat dissipation process does not require manual intervention, avoiding the manpower consumption of manually adjusting the heat dissipation structure, further reducing the operation and maintenance investment of the sewage treatment plant.

[0012] The design of the top block and top rod enables quick removal of the filter element. Operators only need to press the top rod to release the top block from the filter element. After replacing the filter element, releasing the top rod will automatically fix it. The whole process does not require professional tools and can be completed by one person in a short time, which greatly shortens the downtime for filter element replacement and avoids the impact of aeration interruption on the nitrification tank reaction due to maintenance.

[0014] 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 for explaining the present utility model and are not intended to limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] Please see Figures 1 to 5 An aeration blower device for a wastewater nitrification tank is disclosed. The wastewater nitrification tank aeration blower device includes: a device body 1, louvers 4, an adjustment component, and a filter element 5. The device body 1 has a blower body 2 installed inside and an air outlet pipe 3 installed on the top. Louvers 4 for heat dissipation are installed at equal intervals on both sides of the device body 1. An adjustment component is installed between the louvers 4 and the device body 1. The adjustment component drives the louvers 4 to rotate to adjust their opening angle for heat dissipation. A filter element 5 for filtering impurities is installed on the side wall of the device body 1.

[0017] The adjustment assembly includes an electric push rod 6, a crossbar 7, and a rack 8. The electric push rod 6 is fixedly connected to the side wall of the equipment body 1. The output end of the electric push rod 6 is fixedly connected to the crossbar 7. Both ends of the crossbar 7 are fixedly connected to the rack 8. The inside of each louver 4 is fixedly connected to a connecting rod 9. The end of the connecting rod 9 near the rack 8 extends out of the outside of the equipment body 1 and is fixedly connected to a gear 10. The gear 10 meshes with the corresponding rack 8.

[0018] A temperature sensor 11 is fixedly connected to the inner wall of the device body 1.

[0019] The input end of the fan body 2 is fixedly connected to the side wall of the equipment body 1 through the air inlet pipe. A mounting bracket 12 is fixedly connected to the side wall of the equipment body 1 near the air inlet pipe. The filter element 5 is installed inside the mounting bracket 12.

[0020] A top block 13 is slidably connected inside the side wall of the equipment body 1. One end of the top block 13 protrudes from the equipment body 1 and is designed with a chamfer. The other end is fixedly connected to a spring 14. The other end of the spring 14 is fixedly connected to the side wall of the equipment body 1. An inclined groove 15 is opened inside the top block 13.

[0021] The side wall of the equipment body 1 has an installation hole. A push rod 16 is slidably connected inside the installation hole. One end of the push rod 16 is spherical and corresponds to the inclined groove 15. The outer wall of the other end is fitted with a spring 17. One end of the spring 17 is fixedly connected to the inner wall of the installation hole, and the other end is fixedly connected to the outer wall of the push rod 16.

[0022] It should be noted that when the internal temperature of the equipment body 1 exceeds the preset threshold, the electric push rod 6 is activated, and its output end drives the crossbar 7 to move downward. The racks 8 fixed at both ends of the crossbar 7 move downward synchronously with the crossbar 7. Since the racks 8 and the gears 10 at the end of the connecting rod 9 inside the louver 4 mesh with each other, the downward movement of the racks 8 will drive the gears 10 to rotate. The gears 10 and the connecting rod 9 are fixedly connected, so the connecting rod 9 rotates synchronously with the gears 10. The connecting rod 9 passes through and is fixed inside the louver 4, ultimately driving the louver 4 to rotate around the axis of the connecting rod 9, thereby increasing the gap between adjacent louvers 4, that is, expanding the opening of the heat dissipation channel on both sides of the equipment body 1. At this time, the convection speed between the hot air inside the equipment and the cold air outside accelerates, and the hot air is quickly discharged through the expanded gap of the louver 4, achieving a rapid reduction in internal temperature. When the internal temperature of the equipment body 1 drops to within the preset safety threshold range, the output end of the electric push rod 6 retracts inward, pulling the crossbar 7 and the racks 8 at both ends to move upward in the vertical direction; the upward movement of the racks 8 drives the meshing gears 10 to rotate in the opposite direction, which drives the louvers 4 to rotate synchronously through the connecting rod 9, so that the gap between adjacent louvers 4 gradually decreases and the opening of the heat dissipation channel decreases; this process can prevent too much cold air from entering the equipment, especially when the ambient temperature is low, and can prevent internal components from condensing and degrading their insulation performance due to sudden temperature changes, thus maintaining the internal temperature of the equipment within a suitable range.

[0023] The working principle of the aeration blower equipment for the wastewater nitrification tank provided by this utility model is as follows: After the equipment is started, the blower body 2, as the core power component, begins to operate. Its input end draws air from outside the equipment body 1 through the air inlet pipe. The air first passes through the filter element 5 inside the mounting bracket 12 on the side wall of the equipment body 1. The filter element 5 intercepts and filters dust, fine debris, water vapor, and other impurities in the air, preventing these impurities from entering the blower body 2 with the airflow. The purified air enters the blower body 2 and is pressurized by the high-speed rotation of the blower impeller. Finally, it is transported to the wastewater nitrification tank through the air outlet pipe 3 at the top of the equipment body 1, providing sufficient oxygen for the nitrifying bacteria in the tank, meeting the metabolic needs of the nitrification reaction during biological denitrification, and ensuring the stable progress of the wastewater treatment process. During the operation of the blower body 2, its internal core components such as the motor and impeller continuously generate heat due to mechanical friction and energy conversion. This heat accumulates inside the equipment body 1 and needs to be dissipated in a timely manner through the heat dissipation system to maintain normal equipment operation. The specific adjustment process is as follows: Temperature sensor 11 fixed to the inner wall of the equipment body 1... It is in continuous working condition, collecting temperature data inside the equipment in real time and transmitting the data to the equipment control system to form dynamic monitoring of the internal temperature; When the control system determines that the temperature detected by the temperature sensor 11 exceeds the preset threshold, it immediately sends a start command to the electric push rod 6 in the adjustment assembly. After receiving the command, the output end of the electric push rod 6 extends outward, driving the crossbar 7, which is fixedly connected to it, to move downward in the vertical direction. The racks 8 fixed at both ends of the crossbar 7 move downward synchronously with the crossbar 7. Since the racks 8 and the gears 10 at the end of the connecting rod 9 inside the louver 4 mesh with each other, the downward movement of the racks 8 will drive the gears 10 to rotate. The gears 10 and the connecting rod 9 are fixedly connected, so the connecting rod 9 rotates synchronously with the gears 10. The connecting rod 9 passes through and is fixed inside the louver 4, ultimately driving the louver 4 to rotate around the axis of the connecting rod 9, increasing the gap between adjacent louver 4, that is, expanding the heat dissipation channel openings on both sides of the equipment body 1. At this time, the convection speed between the hot air inside the equipment and the cold air outside accelerates, and the hot air is quickly discharged through the expanded gap of the louver 4, achieving a rapid reduction in internal temperature. When the temperature sensor 11 detects that the internal temperature of the equipment has dropped to within the preset safety threshold range, the control system sends a retraction command to the electric push rod 6; the output end of the electric push rod 6 retracts inward, pulling the crossbar 7 and the racks 8 at both ends to move upward in the vertical direction; the upward movement of the racks 8 drives the meshing gears 10 to rotate in the opposite direction, which drives the louvers 4 to rotate synchronously through the connecting rod 9, so that the gap between adjacent louvers 4 gradually decreases and the opening of the heat dissipation channel decreases; this process can prevent too much cold air from entering the equipment, especially when the ambient temperature is low, and can prevent internal components from condensing and degrading insulation performance due to sudden temperature changes, and maintain the internal temperature of the equipment within a suitable range; As the equipment operates for longer periods, a large amount of intercepted impurities will accumulate on the surface of filter element 5, gradually reducing its filtration efficiency. Regular replacement is necessary. The replacement process is achieved through the linkage of top block 13, top rod 16, and two sets of springs. The steps are as follows: The operator first positions the top rod 16 on the side wall of the equipment body 1 corresponding to the filter element 5 and presses it into the equipment body 1. The top rod 16 slides within the mounting hole, compressing and storing elastic potential energy in the spring 17 fitted on its outer wall. Because the end of the top rod 16 near top block 13 is spherical and corresponds to the inclined groove 15 inside top block 13, when the top rod 16 moves inward, the spherical end exerts a horizontal squeezing force on the inclined inner wall of the groove 15. This squeezing force pushes top block 13 against spring 14. The elastic force causes the top block 13 to slide into the device body 1 until the chamfered end of the top block 13 extending out of the device body 1 is completely retracted into the device body 1; at this time, the limiting effect of the top block 13 on the filter element 5 inside the mounting bracket 12 is completely released, and the filter element 5 can be freely removed. The operator pulls the old filter element 5 outward horizontally from the mounting bracket 12, then takes the new filter element 5, aligns it with the internal channel of the mounting bracket 12, and pushes it into the equipment body 1 along the channel until the end of the filter element 5 contacts the inner wall of the mounting bracket 12, confirming that the filter element 5 is completely installed in the designated position. The operator releases the pressed push rod 16, and the compressed spring 17 releases its elastic potential energy, pushing the push rod 16 to move in the opposite direction along the mounting hole to the outside of the equipment body 1. The spherical end of the push rod 16 gradually disengages from the inner wall of the inclined groove 15 of the top block 13, relieving the squeezing force on the top block 13. At this time, the compressed spring 14 simultaneously releases its elastic potential energy, pushing the top block 13 to slide to the outside of the equipment body 1 until the chamfered end of the top block 13 extends out of the side wall of the equipment body 1 and fits tightly against the side wall of the new filter element 5, thus limiting and fixing the filter element 5, completing the replacement operation of the entire filter element 5.
