Description

Technical Field

[0001] The utility model relates to the technical field of sewage aeration treatment, in particular to an automatic condensate pumping and draining device for an aeration system. Background Art

[0002] In the operation of traditional sewage treatment plants, the aeration system is an important component of the biological treatment unit, and its energy consumption accounts for the largest proportion, accounting for about 50% to 80% of the energy consumption of the entire sewage treatment plant. Traditional aeration methods are mainly divided into mechanical aeration and blast aeration. Mechanical aeration mainly stirs the water surface through blades or impellers to allow oxygen in the air to continuously enter the water and oxygenate the water body. Blast aeration mainly uses a blower to transport air to the aerator and transport oxygen to the water body in the form of bubbles. With the development of technology, mechanical aeration has been gradually replaced by blast aeration due to its low aeration efficiency.

[0003] Common underwater aeration equipment includes tubular aerators and disc aerators. Due to the change in temperature difference inside the microporous aerator during day and night, water will condense inside the air duct. Excessive water will cause poor exhaust of the aerator. If the condensed water is not discharged in time, it will easily cause uneven aeration on the one hand, and increase the pressure inside the pipe on the other hand, causing the rubber film to stretch and deform.

[0004] The general way of condensate discharge from aerators is straight pipe outflow, and the condensate is discharged by manually opening the condensate pipe valve regularly. For example, CN217273489U-A large-scale sewage treatment plant aeration system condensate automatic disposal device. This method has the following problems: first, it relies on manual control and is very arbitrary; second, the number is large and the workload is huge, and the efficiency is low; third, considering the safety of the operation, the condensate pipe is generally opened during the day, and it cannot be discharged in time, and the control is not accurate and timely. Utility Model Content

[0005] In view of this, it is necessary to provide an automatic condensate pumping device for an aeration system to solve the technical problem of relying on manual discharge of condensate in the aeration system in the prior art.

[0006] The utility model provides an automatic pumping device for condensed water of an aeration system, which comprises: a water collector, a pumping pipe, a water pump and a collision switch. The drainage pipe of the aeration system is connected to the water collector to discharge condensed water into the water collector. The lower end of the pumping pipe is arranged in the water collector, and the upper end thereof is arranged outside the water collector. The water pump is arranged on the pumping pipe to pump out the condensed water in the water collector. The collision switch is arranged directly below the water collector and is electrically connected to the water pump to control the start or stop of the water pump. The water collector will slide downward under the action of the gravity of the condensed water and contact the collision switch to close the collision switch.

[0007] Furthermore, it also includes a water collecting shell, the upper end of the water collecting shell is closed and the lower end is open, the upper end of the water collector is open, the lower end of the water collecting shell is inserted into the water collector, and the water collector can slide in the vertical direction relative to the water collecting shell.

[0008] Furthermore, it also includes a reset device, which is connected to the water collecting shell and the water collector. The reset device is elastic and can apply an upward pulling force to the water collector to drive the water collector to separate from the collision switch.

[0009] Furthermore, the drain pipe is arranged obliquely, and the lower end of the drain pipe is connected to the water collecting shell.

[0010] Furthermore, the water pumping pipe is arranged to penetrate the upper end of the water collecting shell.

[0011] Furthermore, the drainage pipe includes a fixed pipe and a movable pipe. The fixed pipe passes through the water collecting shell and is fixedly connected to the water collecting shell. The upper end of the movable pipe is inserted into the lower end of the fixed pipe and is movably connected to the fixed pipe. The lower end of the movable pipe extends to the bottom of the water collector.

[0012] Furthermore, a counterweight block is provided at the lower end of the movable tube.

[0013] Furthermore, a plurality of water inlets are provided on the side wall at the lower end of the movable tube.

[0014] Furthermore, the lower end of the movable tube is fixedly connected to the bottom of the water collector.

[0015] Furthermore, the upper end of the movable tube and the lower end of the fixed tube are respectively provided with limit stops, and the two limit stops can abut against each other to prevent the fixed tube and the movable tube from separating.

[0016] Compared with the prior art, the automatic condensate extraction device for the aeration system provided by the utility model uses a water collector to collect condensate. As the amount of condensate in the water collector increases, under the action of gravity, the water collector slides downward and contacts the collision switch, so that the collision switch closes and the water pump starts working to extract the condensate in the water collector, thereby realizing automatic discharge of the condensate. The uncertainty of manual control is avoided, the labor intensity of workers is reduced, and the discharge of condensate is more timely and efficient.

[0022] See also Figure 1 and Figure 2 The utility model provides an automatic pumping device for condensed water in an aeration system. The automatic pumping device for condensed water in an aeration system can be used in sewage treatment or other operations requiring aeration, and is used to automatically discharge condensed water in an aeration system instead of manually.

[0023] The automatic pumping and draining device for condensed water of the aeration system includes a water collector 1, a water pumping pipe 2, a water pump 3 and a collision switch 4. The drainage pipe 9 of the aeration system is connected to the water collector 1 to discharge condensed water into the water collector 1. The lower end of the water pumping pipe 2 is arranged in the water collector 1, and the upper end thereof is arranged outside the water collector 1. The water pump 3 is arranged on the water pumping pipe 2 to extract the condensed water in the water collector 1. The collision switch 4 is arranged directly below the water collector 1 and is electrically connected to the water pump 3 to control the start or stop of the water pump 3. Under the action of the gravity of the condensed water, the water collector 1 will slide downward and contact the collision switch 4 to close the collision switch 4, and start the water pump 3 to pump water. A relay can be set on the circuit of the water pump 3 and the collision switch 4.

As the amount of condensate in the water collector increases, under the action of gravity, the water collector slides downward and contacts the collision switch, so that the collision switch closes and the water pump starts working to extract the condensate in the water collector, thereby realizing automatic discharge of the condensate.
