Description

Technical Field

[0001] This utility model relates to a sewage treatment device with influent flow monitoring, belonging to the field of sewage treatment technology. Background Technology

[0002] With the rapid advancement of industrialization and urbanization, the demand for water resources is increasing daily, making water quality assurance and energy consumption control particularly important. As a key piece of equipment in water treatment systems, the performance of influent booster pumps directly affects the overall system's operational efficiency and stability. Currently, influent booster pumps on the market have many shortcomings in operation, such as high energy consumption, low efficiency, and high maintenance costs. Therefore, conducting research on influent booster optimization can not only improve water resource utilization efficiency but also reduce operating costs, which is of great significance for promoting sustainable development.

[0003] Wastewater lift pumps and flow meters are crucial equipment in wastewater treatment systems, and their proper operation is essential to ensuring the continuity and efficiency of the wastewater treatment process. A malfunctioning wastewater lift pump not only reduces the operational efficiency of wastewater treatment but also affects the measurement accuracy of the flow meter; failure to replace a faulty lift pump will result in invalid flow detection by the flow meter, shortening its lifespan.

Detailed Implementation

[0016] 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.

[0017] Please see Figures 1-5This utility model provides a technical solution, which is a sewage treatment device with influent flow monitoring, including a sewage lift pump 20 and a sewage pipe 30 installed at the influent of the sewage treatment tank 10. The sewage lift pump 20 includes a pump body 21 and a second base 23, and the sewage pipe 30 includes a main pipe 31, a drainage pipe 32 and an influent pipe 36. Wherein: the bottom of the pump body 21 is detachably mounted on the second base 23, the water inlet pipe 36 is detachably connected to the water inlet end of the pump body 21, and the main pipe 31 is detachably connected to the drain end of the pump body 21. Since the sewage lift pump 20 is prone to damage and malfunction during use, this embodiment makes it easier to disassemble and assemble the sewage lift pump 20 by detachably connecting the pump body 21 to the second base 23, the water inlet pipe 36, and the main pipe 31, thus facilitating the replacement of the sewage lift pump 20. It should be noted that in this embodiment, the detachable connection between the pump body 21 and the second base 23 can be achieved using bolts and nuts, and the detachable connection between the pump body 21 and the water inlet pipe 36 and the main pipe 31 can be achieved using flanges.

[0018] In this embodiment, the drainage pipe 32 is fixedly installed on the main pipe 31. One end of the drainage pipe 32 is connected to the main pipe 31, and the other end of the drainage pipe 32 is bent, with the bent end extending into the sewage treatment tank 10 so that the sewage after passing through the sewage lift pump 20 enters the sewage treatment tank 10 at a certain flow rate. Furthermore, in this embodiment, a flow meter 33 is installed on the drainage pipe 32. The flow meter 33 is used to display the sewage flow rate and velocity inside the drainage pipe 32 in real time, thereby monitoring the influent flow rate to the sewage treatment tank 10.

[0019] In the embodiments of this application, such as Figures 2-5As shown, it also includes a piston mechanism 40, which includes a sleeve 34 fixedly installed outside the main pipe 31, a piston disposed inside the main pipe 31, and a piston rod 41 fixedly connected to the piston. The piston is slidably installed inside the main pipe 31. One end of the piston rod 41 is fixedly connected to the piston, and the other end of the piston rod 41 extends into the sleeve 34. The end of the piston rod 41 extending into the sleeve 34 is connected to the sleeve 34 through a return spring 42. The piston rod 41 is slidably connected to the main pipe 31. When the sewage lift pump 20 is in normal working condition, the sewage entering the main pipe 31 applies pressure to the piston, causing the piston to squeeze the return spring 42 through the piston rod 41. When the sewage lift pump 20 is in an abnormal state, the amount of sewage entering the main pipe 31 decreases sharply. At this time, the piston and piston rod 41 move towards the drain end of the pump body 21 from the left and right sides of the return spring 42. The connection between the main pipe 31 and the drain pipe 32 is blocked by the piston. At this time, sewage cannot enter the interior of the drain pipe 32, thereby reducing the frequency of use of the flow meter 33 and extending the service life of the flow meter 33.

[0020] Furthermore, in this embodiment of the application, in order to facilitate the disassembly of the pump body 21, the sewage lift pump 20 is also provided with a first base 22, a first support frame 24 and a second support frame 26 on its periphery. The second base 23 is fixedly connected to the first base 22, the first support frame 24 and the second support frame 26 are connected to the first base 22, and the first support frame 24 is connected to the water inlet pipe 36. The second base 23 is connected to the sleeve 34.

[0021] Furthermore, in this embodiment, a connecting frame 25 is also included. The first support frame 24, the connecting frame 25, and the second support frame 26 are all hollow structures. Specifically: a sliding sleeve 44 and a rack 45 are slidably installed inside the second support frame 26, the sliding sleeve 44 and the rack 45 are fixedly connected, and the sliding sleeve 44 is fixedly connected to the piston rod 41; a rotating gear 46 is also rotatably installed inside the second support frame 26, the rotating gear 46 meshing with the rack 45; a first rotating shaft 38, a first bevel gear 381, and a second bevel gear 382 are rotatably installed inside the first support frame 24; a butterfly valve 37 is rotatably installed inside the water inlet pipe 36, the butterfly valve 37 is fixedly connected to the first rotating shaft 38, the first rotating shaft 38 is fixedly connected to the first bevel gear 381, and the first bevel gear 381 meshes with the second bevel gear 382; a synchronous belt 383 is provided inside the connecting frame 25, and the second bevel gear 382 is connected to the rotating gear 46 via the synchronous belt 383.

[0022] Understandably, when the pump body 21 of the sewage lift pump 20 is damaged, the piston rod 41 controls the butterfly valve 37 to rotate through the transmission mechanism set inside the first support frame 24, the connecting frame 25 and the second support frame 26, so that the butterfly valve 37 closes the inlet pipe 36, preventing sewage from continuously entering the interior of the pump body 21, and providing a guarantee for the disassembly and replacement of the pump body 21.

[0023] like Figures 2-3 As shown in this embodiment, a power supply 35 is provided outside the sleeve 34, and a resilient button 43 is provided inside the sleeve 34. The resilient button 43 is electrically connected to the power supply 35, and the power supply 35 is electrically connected to the flow meter 33 through a wire 39. When the pump body 21 is in a normal state, the piston rod 41 applies pressure to the resilient button 43, causing the resilient button 43 to close. After the resilient button 43 closes, the power supply 35 supplies power to the flow meter 33, which starts and monitors the flow rate of the incoming sewage. When the pump body 21 is in an abnormal state, the piston rod 41 moves away from the resilient button 43, the resilient button 43 disconnects from the power supply 35, and the flow meter 33 shuts down after losing power, thereby reducing the frequency of use of the flow meter 33.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
