Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment sludge pipeline dredging device. Background Technology

[0002] A large amount of sludge is generated during the biological treatment of sewage. The sludge needs to be transported and processed during the treatment process. During the long-term use of sludge transport pipelines, sludge deposition is inevitable. At this time, it is necessary to clean the pipelines to avoid affecting their stable use.

[0003] The traditional method of cleaning is manual disassembly. Because sludge pipes are generally long, the pipe joints are disassembled and then cleaned by flushing with water. This process is done section by section, which is time-consuming and labor-intensive, and causes inconvenience to actual production. Existing pipe cleaning devices, such as cleaning carts, often require power transmission, which is not convenient for use in cleaning sludge pipes, as the pipe diameter is generally small.

[0004] Therefore, this application proposes a sludge pipe dredging device, which cleans the pipe without disassembling it, making it convenient and efficient, effectively improving cleaning efficiency and bringing convenience to actual production. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the existing technology by providing a sewage treatment sludge pipeline dredging device, so as to facilitate the cleaning of sludge pipelines in sewage treatment plants.

[0007] Furthermore, a frame is provided around the outer periphery of the central tube. The frame includes multiple annular portions arranged along the axial direction of the central tube and connecting portions connecting the annular portions. The annular portions on both sides of the frame are fixedly connected to the central tube through connecting brackets.

[0008] Furthermore, the walking device is connected to the annular portions on both sides of the frame respectively; multiple walking devices are provided on each annular portion, each walking device includes a sleeve, a telescopic rod is limited in the sleeve, a spring is provided between the bottom of the sleeve and the end of the telescopic rod, and a roller is mounted on the front end of the telescopic rod, the roller cooperating with the inner wall of the pipe.

[0009] Furthermore, the central tube includes a first part and a second part, and the annular portions on both sides of the frame are connected to the first part and the second part respectively; the first part is connected to the first rotary joint, the second part is connected to the second rotary joint, a rotating drum is connected between the first rotary joint and the second rotary joint, and spray pipes are arranged around the rotating drum, with the water outlet direction of the spray pipes arranged tangentially.

[0010] Furthermore, a nozzle is installed at the end of the nozzle.

[0011] Furthermore, the water outlet pipe has a certain length, and the water sprayed from the tail of the pagoda-shaped rotating nozzle does not interfere with the central pipe.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model can dredge the inside of sludge pipes. The walking device can also be used for pipes of different diameters, and it can also make the walking device fit more tightly with the pipe wall, ensuring the stability of use.

[0014] 2. During use, this utility model relies solely on the recoil force of the water jet from the pagoda-shaped rotating nozzle as its power source, requiring no additional power, making it more convenient and easy to use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0023] Embodiments of this utility model:

[0024] like Figures 1-4 As shown, this utility model is used for cleaning sludge accumulated in sludge pipe 1 of a sewage treatment plant.

[0025] The unblocking device 2 of this utility model is provided with a central pipe 21 and a frame 23 is provided outside the central pipe 21. The frame 23 includes an annular portion 231 arranged along the axial direction of the central pipe 21 and a connecting portion 232 connecting each annular portion 231. The frame 23 is cage-shaped in whole. The annular portions 231 on both sides of the frame 23 are connected to the central pipe 21 through a connecting frame 22.

[0026] A walking device 24 is connected to the annular portion 231 on both sides of the frame 23. The walking device 24 includes a sleeve 241, which is fixedly connected to the annular portion 231. A telescopic rod 242 is inserted into the sleeve 241 for limiting. The limiting mechanism 243 includes an annular baffle at the front end of the sleeve 241 and an annular plate at the bottom periphery of the telescopic rod 242 that is larger than the diameter of the telescopic rod 242. A spring 244 is provided between the telescopic rod 242 and the bottom of the sleeve 241. A roller 245 is mounted at the front end of the telescopic rod 242.

[0027] The central tube 21 is divided into a first part 211 and a second part 212. The walking devices 24 on both sides are located on the first part 211 and the second part 212 respectively. The first part 211 is connected to the first rotary joint 25, and the second part 212 is connected to the second rotary joint 27. A rotating drum 26 is connected between the first part 211 and the second part 212. A spray pipe 261 is provided on the outer periphery of the rotating drum 26. A nozzle 262 is provided at the end of the spray pipe 261. The water outlet direction of the nozzle 262 is tangential to the rotating drum 26.

[0028] The water outlet pipe 2121 is provided with the front end of the second part 212. A pagoda rotating nozzle 28 is installed at the front end of the water outlet pipe 2121. The water outlet pipe 2121 has a certain length so that the water from the pagoda rotating nozzle 28 does not impact the central pipe 21.

[0029] The principle of this utility model is as follows:

[0030] When using this utility model, the unblocking device 2 is placed in the sludge pipe 1 that needs to be cleaned. In actual production, the diameter of the sludge pipe 1 is generally 200mm, but other specifications also exist. During the process, the elastic extension and retraction of the walking device 24 can adapt to sludge pipes 1 with different pipe diameter specifications, and at the same time, it makes the device more stable to use.

[0031] After placing the unblocking device 2 into the sludge pipe 1, connect the inlet 2111 to the high-pressure water pipe. Under the action of water pressure, the water flows to fill the central pipe 21, and part of it enters the pagoda rotating nozzle 28 through the outlet pipe 2121. The pagoda rotating nozzle 28 is commercially available and has the functions of breaking up obstacles, cleaning, and propulsion. Since it is a mature product, its structural principle will not be described in detail. However, it should be noted that during use, the water sprayed from the tail of the pagoda rotating nozzle 28 (the water sprayed from the tail acts as a propulsion device, the water sprayed from the front periphery acts as a cleaning device, and the drill bit at the front acts as an obstacle-breaking device) should be prevented from spraying directly onto the central pipe 21. In this case, the outlet pipe 2121 needs to have a certain length. If the angle between the water sprayed from the tail of the pagoda rotating nozzle 28 and the horizontal plane is 30° (the tail water diffuses and sprays out), and the radius of the central pipe 21 is a, then the length of the outlet pipe 2121 must be at least greater than 0.5.

[0032] Another part of the water flow is sprayed tangentially through the rotating drum 26 in the middle of the central pipe 21. After the front pagoda rotating nozzle 28 cleans the pipe wall once, the rear rotating drum 26 can perform a second cleaning of the pipe wall, making the cleaning effect better.

[0033] This invention requires no additional power source; the water jet from the pagoda-shaped rotating nozzle 28 provides the propulsion, making it more convenient and easy to use. The pagoda-shaped rotating nozzle 28, the rotary joint, and the nozzle itself are all existing, mature products, and all are commercially available. Specifically, the pagoda-shaped rotating nozzle 28 was purchased from Hebei Tiandao Technology Co., Ltd.; the rotary joint was purchased from Shandong Jiangsheng Machinery Technology Co., Ltd.; and the nozzle 262 is a fan-shaped nozzle 262, purchased from Shandong Yatemei Environmental Technology Co., Ltd.
