Description

Technical Field

[0001] This utility model relates to a drainage treatment device, specifically a drainage treatment device for municipal engineering, and belongs to the field of municipal engineering drainage treatment technology. Background Technology

[0002] Municipal engineering drainage treatment refers to the collection, transportation, treatment and discharge of sewage and rainwater generated in cities through a series of engineering facilities and technical means, in order to ensure the hygiene, safety and sustainable development of the urban environment. This process is an important part of municipal engineering, and its core objectives include protecting the environment, preventing pollution, protecting residents' health and maintaining the normal operation of the city.

[0003] Chinese Patent Publication CN220090614U discloses a municipal drainage treatment device. Through a collection box and an observation window, workers can observe the amount of garbage accumulation to determine whether it is causing blockage of the drainage device. This allows workers to promptly remove and empty the garbage from the collection box, thus ensuring the normal operation of the drainage treatment device.

[0004] The aforementioned patented technology requires staff to observe the amount of accumulated waste through an observation window, which significantly increases their workload. Furthermore, when staff cannot immediately observe the waste accumulation, it can exacerbate blockages. Additionally, pulling out the collection box to clear blockages temporarily disables the treatment device, thus affecting efficiency. Therefore, this paper proposes a drainage treatment device for municipal engineering. Utility Model Content

[0005] This utility model proposes a drainage treatment device for municipal engineering to solve the problem that manual observation and cleaning of blockages in the prior art can easily increase blockages and affect treatment efficiency.

[0006] This utility model is achieved through the following technical solution: a drainage treatment device for municipal engineering, including a treatment tank, wherein a replacement mechanism is provided inside the treatment tank;

[0007] The replacement mechanism includes a fixed frame, the outer surface of which is slidably connected to the inner wall of the treatment box. A first multi-stage electric push rod is fixedly connected to the back of the fixed frame, and the back of the first multi-stage electric push rod is fixedly connected to the front of the treatment box. Water guide pipes are fixedly connected to the upper and lower surfaces of the treatment box, and a flow meter is fixedly connected to the outer surface of each water guide pipe. A controller is fixedly connected to the front of the treatment box, and an alarm is fixedly connected to the upper surface of the treatment box. Two filter plates and two filter screens are fixedly connected to the inner wall of the fixed frame.

[0008] The processing box is equipped with a blocking component inside.

[0009] The blocking assembly includes a baffle, the outer surface of which is slidably connected to the inner wall of the processing box, and a second multi-stage electric push rod is fixedly connected to the back of the baffle, the back of which is fixedly connected to the front of the processing box.

[0010] The bottom surface of the processing box is fixedly connected to four positioning frames, and each positioning frame has a positioning hole on its upper surface.

[0011] The two water pipes are fixedly connected to flanges at their far ends, and each flange has six bolts threaded onto its inner wall.

[0012] The inner wall of the baffle and the inner wall of the fixed frame are slidably connected with positioning posts, and the back of each positioning post is fixedly connected to the front of the processing box.

[0013] The upper and lower surfaces of the baffle are fixedly connected with a first sealing gasket, and the upper and lower surfaces of the fixed frame are fixedly connected with a second sealing gasket. The outer surfaces of the first and second sealing gaskets are in contact with the inner wall of the processing box.

[0014] This utility model provides a drainage treatment device for municipal engineering, which has the following beneficial effects:

[0015] 1. The drainage treatment device used in this municipal engineering project monitors the changes in inlet and outlet water flow in real time through a flow meter on the water pipe and transmits the data to the controller. When the difference between the inlet and outlet water flow reaches a set threshold due to blockage by garbage, the controller will automatically trigger an alarm to issue a warning. This eliminates the need for staff to be on duty at all times, greatly reducing the frequency and intensity of manual inspections. At the same time, it will also control the activation of the first multi-stage electric push rod, which can drive the fixed frame to automatically move the filter plates and screens in the treatment box out of the treatment box, while simultaneously moving the filter plates and screens on the other side into the treatment box, thus effectively replacing them. This also avoids the problem of not being able to continue the treatment work when the staff pulls out the filtration equipment for cleaning.

[0016] 2. The drainage treatment device used in this municipal engineering project has a baffle that can separate the treatment tank. When the filter plate on one side becomes clogged, the controller will first activate the second multi-stage electric push rod to push the baffle to close, temporarily blocking the water flow through the filtration area inside the treatment tank, so that the water to be treated can be temporarily stored in the upper part of the treatment tank. Once the baffle is replaced, it can be reset and the treatment work can continue. Because the replacement process is short, it can greatly reduce the impact on the efficiency of the treatment work.

[0023] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0024] Please see Figures 1-4 This utility model provides a drainage treatment device for municipal engineering, including a treatment box 1, and a replacement mechanism 2 is provided inside the treatment box 1.

[0025] The replacement mechanism 2 includes a fixed frame 201, the outer surface of which is slidably connected to the inner wall of the treatment box 1. A first multi-stage electric push rod 202 is fixedly connected to the back of the fixed frame 201. The back of the first multi-stage electric push rod 202 is fixedly connected to the front of the treatment box 1. Water guide pipes 203 are fixedly connected to the upper and lower surfaces of the treatment box 1. Four positioning frames 4 are fixedly connected to the bottom surface of the treatment box 1. Each positioning frame 4 has a positioning hole 5 on its upper surface. The positioning frame 4 can significantly improve the stability and anti-overturning ability of the entire drainage treatment device. The design of the positioning frame 4 not only provides support, but the positioning hole 5 on its upper surface makes it easy to use screws or other fasteners to firmly fix the treatment box 1 to the foundation or a preset installation platform, ensuring the stability of the device during long-term operation.

[0026] Please refer to this carefully. Figure 1 and Figure 2Each water pipe 203 has a flow meter 204 fixedly connected to its outer surface. A controller 205 is fixedly connected to the front of the treatment box 1, and an alarm 206 is fixedly connected to the upper surface of the treatment box 1. Two filter plates 207 and two filter screens 208 are fixedly connected to the inner wall of the fixed frame 201. Flanges 6 are fixedly connected to the ends of the two water pipes 203 that are far apart from each other. Six bolts 7 are threadedly connected to the inner wall of each flange 6. The flanges 6 are fixedly connected to the ends of the water pipes 203, and six bolts 7 are provided for threaded connection. This greatly enhances the convenience and sealing of connecting the water pipes 203 to other pipes or equipment. The flanges 6 provide a standard connection interface, which allows the drainage treatment device to be easily connected to the existing municipal drainage network or other treatment units. The tightening of the six bolts 7 ensures the tightness of the connection and effectively prevents water leakage at the connection, thus ensuring the airtightness and operating efficiency of the entire drainage system.

[0027] Please refer to this carefully. Figure 2 and Figure 3 The treatment box 1 is equipped with a blocking assembly 3, which includes a baffle 301. The outer surface of the baffle 301 is slidably connected to the inner wall of the treatment box 1. A second multi-stage electric push rod 302 is fixedly connected to the back of the baffle 301. The back of the second multi-stage electric push rod 302 is fixedly connected to the front of the treatment box 1. By setting the baffle 301, it can work in conjunction with the fixed frame 201. When it is necessary to replace the filter plate 207 and the filter screen 208, the baffle 301 can slide along the inner wall of the treatment box 1 under the drive of the second multi-stage electric push rod 302, thereby forming a temporary isolation area. This facilitates the movement of the fixed frame 201 and the replacement of the filter media, avoids water leakage, and improves maintenance efficiency and safety. The multi-stage structure of the second multi-stage electric push rod 302 provides greater stroke and thrust.

[0028] Please refer to this carefully. Figure 2 The inner wall of the baffle 301 and the inner wall of the fixed frame 201 are slidably connected with positioning posts 8. The back of each positioning post 8 is fixedly connected to the front of the processing box 1. The positioning posts 8 form a fixed guide rail inside the processing box 1. The baffle 301 and the fixed frame 201 slide along the positioning posts 8, ensuring their straightness and stability during movement and avoiding deviation or shaking.

[0029] Please refer to this carefully. Figure 3The upper and lower surfaces of the baffle 301 are fixedly connected with a first sealing gasket 9, and the upper and lower surfaces of the fixing frame 201 are fixedly connected with a second sealing gasket 10. The outer surfaces of the first sealing gasket 9 and the second sealing gasket 10 are in contact with the inner wall of the treatment tank 1. The first sealing gasket 9 will stick tightly to the inner wall of the treatment tank 1 to block the water flow. Similarly, when the fixing frame 201 moves or is stationary, the second sealing gasket 10 can also form a seal with the inner wall of the treatment tank 1 it contacts. This sealing design prevents untreated sewage inside the treatment tank 1 from leaking from the gap between the baffle 301 or the fixing frame 201 and the tank wall, ensuring the closedness of the treatment process and avoiding environmental pollution.

[0030] When using this utility model: First, the operator connects the first multi-stage electric push rod 202, flow meter 204, controller 205, alarm 206, and second multi-stage electric push rod 302 to the power supply, and connects the first multi-stage electric push rod 202, flow meter 204, alarm 206, and second multi-stage electric push rod 302 to the controller 205 for easy control. Then, the operator connects the upper water guide pipe 203 to the municipal drainage network pipeline through the flange 6, and the lower water guide pipe 203 to the outlet pipe.

[0031] Then, the controller 205 and flow meter 204 are turned on. Water then enters the upper guide pipe 203 through the municipal drainage network. The water flows into the treatment tank 1 through the guide pipe 203. At this time, the filter plate 207 and filter screen 208 begin to perform their filtering function, intercepting impurities in the sewage and purifying the water flow. The filter plate 207 blocks large garbage in the water. At the same time, the flow meter 204 monitors the water flow in real time and feeds the data back to the controller 205. When the water flow is abnormal, such as when the difference between the inlet and outlet water flow is large due to garbage blockage and reaches the set threshold, the controller 205 will react quickly and trigger the alarm 206 to sound an alarm, reminding the staff to deal with it in time.

[0032] When a blockage occurs, the controller 205 first activates the second multi-stage electric push rod 302. The second multi-stage electric push rod 302 pushes the baffle 301 to slide along the positioning post 8, forming a temporary isolation area inside the treatment tank 1, allowing the water to be treated to be temporarily stored in the upper part of the treatment tank 1. The controller 205 then activates the first multi-stage electric push rod 202. The first multi-stage electric push rod 202 pushes the fixing frame 201, carrying the filter plate 207 and filter screen 208 inside the treatment tank 1, to slide out of the treatment tank 1 along the positioning post 8. At the same time, it also brings the filter plate 207 and filter screen 208 on the other side into the treatment tank 1, thus effectively replacing them. After the replacement is completed, the baffle 301 is reset, and the drainage treatment device continues to operate normally, continuously and effectively treating municipal sewage to ensure that the drainage meets relevant standards.
