Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, specifically to a mid-course booster device for wastewater treatment. Background Technology

[0002] Booster pumps, also known as intermediate booster pumps, are a common type of water pump used in wastewater treatment. Their main function is to increase the water flow rate and pressure to meet specific flow and pressure requirements, playing a crucial role in rural wastewater treatment.

[0003] During the process of pressurizing sewage, existing booster pumps often encounter problems. Because sewage contains a lot of impurities and booster pumps lack anti-clogging designs, a large amount of impurities can easily clog the booster pump during long-term pressurization. This blockage can lead to increased pressure loss inside the booster pump, affecting its performance. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose a mid-course pressurization device for sewage treatment to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a mid-course booster device for sewage treatment, including a booster pump. A filter pipe is detachably installed at the input end of the booster pump. An external pipe is detachably installed at the end of the filter pipe away from the booster pump. A connecting pipe is fixedly connected to the filter pipe. A winding wheel is rotatably connected to the bottom of the inner wall of the filter pipe. A filter screen is wound around the outer surface of the winding wheel. A guide wheel is provided at the top of the inner wall of the filter pipe. A load-bearing block is provided at the end of the filter screen away from the winding wheel. A pressure-bearing mechanism and an alarm triggering mechanism are respectively provided on the connecting pipe.

[0006] Preferably, a rubber plug is provided on the outer surface of the load-bearing block, and the outer surface of the rubber plug is slidably connected to the inner wall of the connecting pipe.

[0007] Preferably, the pressure-bearing mechanism includes a displacement rod fixedly connected to the bottom of the load-bearing block. A spring is movably sleeved on the outer surface of the displacement rod, and an I-shaped guide is provided at the bottom of the displacement rod. The pressure-bearing mechanism can work in conjunction with the alarm triggering mechanism to provide a warning effect (reminding the outside world of the accumulation of impurities on the filter screen inside the connecting pipe).

[0008] Preferably, the alarm triggering mechanism includes a fixing strip fixedly connected to the outer surface of the connecting pipe, a bar shaft fixedly passing through the bottom end of the fixing strip, and a swing arm rotatably connected to the outer surface of the bar shaft. The alarm triggering mechanism can trigger an alarm light to sound an alarm, thereby reminding technicians that the filter screen needs to be cleaned.

[0009] Preferably, a contact shaft is fixedly connected to the bottom end of the swing arm, and a trigger ball is provided at the top end of the swing arm.

[0010] Preferably, an alarm light is provided on the outer surface of the connecting pipe, and a switch is provided on the alarm light.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This wastewater treatment uses a mid-course pressurization device. The filter screen can filter the wastewater passing through. During the process, as more impurities adhere to the filter screen, the load-bearing block will pull one end of the filter screen down. In conjunction with the guide wheel and the winding wheel, the filter screen that is not heavily clogged (i.e., the "new" filter screen part) is tilted and placed on the part of the filter screen that filters wastewater, thereby increasing the filtration efficiency.

[0013] 2. The wastewater treatment system uses a mid-course booster device and an automatic cleaning reminder mechanism for the filter screen. When the accumulated impurities on the filter screen reach a certain weight, the alarm is automatically triggered through the linkage of components such as the load-bearing block, spring, displacement rod, I-shaped guide table, swing arm, trigger ball, and alarm light, reminding technicians to clean the filter screen in time. This design reduces the frequency of manual inspection and reduces equipment failures and downtime caused by blockage. Attached Figure Description

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Please see Figure 1-3A wastewater treatment intermediate booster device includes a booster pump 1. A filter pipe 2 is detachably installed at the input end of the booster pump 1. Both ends of the filter pipe 2 are fixedly connected to the booster pump 1 and an external pipe 3 via flanges and bolts, respectively. Therefore, the filter pipe 2 is detachable. An external pipe 3 is detachably installed at the end of the filter pipe 2 away from the booster pump 1. A connecting pipe 4 is fixedly connected to the filter pipe 2. A winding wheel 5 is rotatably connected to the bottom of the inner wall of the filter pipe 2. A filter screen 6 is wound around the outer surface of the winding wheel 5. A guide wheel 7 is provided at the top of the inner wall of the filter pipe 2. A load-bearing block 8 is provided at the end of the filter screen 6 away from the winding wheel 5. In the initial state, the top of the load-bearing block 8 is flush with the bottom of the filter pipe 2. A pressure-bearing mechanism and an alarm triggering mechanism are respectively provided on the connecting pipe 4.

[0020] Through the above technical solution, during the process of transporting sewage through rural sewage pipelines, the booster pump 1 can pressurize the sewage midway. Before entering the booster pump 1, the sewage will be filtered by the filter screen 6. During this process, as the impurities on the filter screen 6 gradually increase to a certain extent, the alarm light 18 will be triggered by the pressure-bearing mechanism and the alarm triggering mechanism to issue an alarm, thereby reminding the outside world that the filter screen 6 needs to be cleaned.

[0021] Specifically, a rubber plug 9 is provided on the outer surface of the load-bearing block 8, and the outer surface of the rubber plug 9 is slidably connected to the inner wall of the connecting pipe 4.

[0022] With the above technical solution, as the load-bearing block 8 and the rubber stopper 9 slide downwards, water will not seep into the connecting pipe 4 located below the load-bearing block 8.

[0023] Specifically, the pressure-bearing mechanism includes a displacement rod 10 fixedly connected to the bottom of the load-bearing block 8, a spring 11 movably sleeved on the outer surface of the displacement rod 10, and an I-shaped guide platform 12 provided at the bottom of the displacement rod 10.

[0024] Through the above technical solution, as the shift rod 10 moves downward with the load block 8, the spring 11 will be compressed and deformed. The I-shaped design of the I-shaped guide table 12 is for more convenient prying of the contact shaft 16.

[0025] Specifically, the alarm triggering mechanism includes a fixing strip 13 fixedly connected to the outer surface of the connecting pipe 4, a strip shaft 14 fixedly passing through the bottom end of the fixing strip 13, and a swing arm 15 rotatably connected to the outer surface of the strip shaft 14.

[0026] Through the above technical solution, as the swing arm 15 rotates along the bar axis 14, the trigger balls 17 at its upper and lower ends and the contact shaft 16 will deflect synchronously, and the entire fixed bar 13 and related components such as the swing arm 15 are symmetrically distributed on the outer periphery of the connecting pipe 4.

[0027] Specifically, a contact shaft 16 is fixedly connected to the bottom end of the swing arm 15, and a trigger ball 17 is provided at the top end of the swing arm 15.

[0028] Through the above technical solution, the contact shaft 16 at the bottom of the swing arm 15 will gradually move away from the connecting pipe 4, while the trigger ball 17 at the top of the swing arm 15 will gradually move closer to the alarm light 18 on the outer surface of the connecting pipe 4.

[0029] Specifically, an alarm light 18 is provided on the outer surface of the connecting pipe 4, and a switch 19 is provided on the alarm light 18.

[0030] With the above technical solution, when the trigger ball 17 contacts the switch 19 on the alarm light 18 during the deflection process, the alarm light 18 will be activated, and at this time the alarm light 18 will produce a bright and piercing alarm sound.

[0031] Working principle: During the sewage transportation process in rural sewage pipelines, the booster pump 1 can pressurize the sewage midway. Before entering the booster pump 1, the sewage enters the filter pipe 2 through the external pipe 3 and is filtered by the filter screen 6 inside the filter pipe 2. During this process, the filter screen 6 filters impurities in the sewage. As more and more impurities accumulate on the filter screen 6 (it should be noted that the impurities attached to the filter screen 6 mainly accumulate on the side of the triangular filter screen 6 connected to the load-bearing block 8), the load-bearing block 8 will bear increasing gravity, which will cause the load-bearing block 8 to pull the filter screen 6 down along the inside of the connecting pipe 4. During this process, the filter screen 6 will pass the outer surface of the guide wheel 7, and the filter screen 6 wrapped on the surface of the take-up wheel 5 will gradually unfold, allowing the unblocked part of the filter screen 6 to be tilted inside the filter pipe 2. This serves to continue and optimize the filtration effect. As impurities on the filter screen 6 accumulate to a certain weight, the downward movement of the load-bearing block 8 compresses the spring 11. The downward movement of the shift rod 10 causes the I-shaped guide table 12 to move downward simultaneously. During the downward movement, the I-shaped guide table 12 moves the contact shaft 16, causing the swing arm 15 to rotate along the bar shaft 14. This continues until the trigger ball 17 triggers the switch 19 as it approaches the connecting pipe 4, thus turning on the alarm light 18. The alarm light 18 produces a bright light and a piercing alarm sound, alerting external technicians that too many impurities have accumulated on the filter screen 6 inside the filter tube 2, requiring cleaning. At this point, technicians only need to disconnect the flange connecting the filter tube 2 to the booster pump 1 at the end and the external pipe 3 to disassemble the filter tube 2 for systematic cleaning.

[0032] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
