Description

Technical Field

[0001] This utility model relates to the field of sewage pump pipeline anti-clogging technology, specifically a sewage pump pipeline anti-clogging structure for sponge cities. Background Technology

[0002] In the construction and development of sponge cities, the sewage system, as a key component of urban infrastructure, undertakes the important task of collecting and discharging urban sewage and rainwater. However, in actual operation, sewage pump pipes often face the problem of blockage. Since urban sewage and rainwater inevitably contain various impurities, large particles and fibrous materials are particularly common. These large particles, such as stones and branches, and fibrous materials, such as hair and fabric fibers, are very easy to accumulate and entangle inside the sewage pump pipes after entering them, thus causing blockage. Once the pipes are blocked, it will not only seriously affect the normal operation of the sewage system, preventing sewage and rainwater from being discharged in time, but may also cause a series of serious problems such as urban flooding, causing great inconvenience to the normal operation of the city and the lives of residents.

[0003] While some anti-clogging technologies exist to address the problem of sewage pump pipe blockage, they all have limitations. For example, some anti-clogging devices only treat a single type of impurity, either dealing only with large particles or only having some effect on fibrous materials, failing to effectively treat both large particles and fibrous impurities simultaneously. This makes it difficult to meet the needs of the complex sewage environment in sponge cities, and the anti-clogging effect is unstable, easily leading to the failure of the anti-clogging function. Therefore, we propose an anti-clogging structure for sewage pump pipes in sponge cities to solve the above-mentioned problems. Utility Model Content

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] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 A sponge city sewage pump pipeline anti-clogging structure includes a large particle crushing mechanism and a fiber crushing mechanism. During installation, the housing 1 is first placed stably in a suitable position to ensure its secure installation. Then, the input pipe 5 and the output pipe 2 are installed. The input pipe 5 is installed on the side of the housing 1 near the inside where the crushing teeth 9 are installed, and the output pipe 2 is installed on the side of the housing 1 near the inside where the first tearing teeth 7 are installed. The input pipe 5 and the output pipe 2 are then securely connected to the external pipeline through a connecting flange. Subsequently, the gearbox 3 is installed and fixed to the top of the housing 1. The drive motor 4 is then installed on the top of the gearbox 3, and the output end of the drive motor 4 is accurately connected to the input end of the gearbox 3.

[0018] Next, the internal rotating components are installed. The bottom ends of the two first rotating shafts 11 are rotatably connected to the bottom inner wall of the housing 1, and the top ends are connected to two output ends of the gearbox 3. The first rotating roller 6 is installed on the first rotating shaft 11, and then multiple crushing teeth 9 are evenly installed on the outer ring of the first rotating roller 6, and the multiple crushing teeth 9 on the two first rotating rollers 6 are installed in a staggered manner.

[0019] Similarly, the bottom ends of the two second rotating shafts 12 are rotatably connected to the bottom inner wall of the housing 1, and the top ends are connected to the other two output ends of the gearbox 3. The second rotating roller 8 is installed on the outer ring of the second rotating shaft 12, and multiple first tearing teeth 7 are evenly installed on the outer ring of the second rotating roller 8, so that the multiple first tearing teeth 7 on the two second rotating rollers 8 are installed in a staggered manner. At the same time, multiple second tearing teeth 10 are installed on the side wall of the housing 1 near the second rotating roller 8.

[0020] After installation, start the drive motor 4. The drive motor 4 drives the gearbox 3 to rotate. The gearbox 3 drives the two first rotating shafts 11 and the two second rotating shafts 12 to rotate through the four output ends. The two first rotating shafts 11 drive the two first rotating rollers 6 to rotate in opposite directions. The misaligned crushing teeth 9 crush large particles of impurities entering from the input pipe 5. The two second rotating shafts 12 drive the two second rotating rollers 8 to rotate in the same direction. The misaligned first tearing teeth 7 and second tearing teeth 10 cooperate to tear and crush fibrous impurities. The crushed material is discharged from the output pipe 2.

[0021] Example 2: Please refer to Figure 1 , Figure 2 and Figure 3The casing 1 can be treated with anti-corrosion coating to adapt to possible humid and corrosive environments. When installing the input pipe 5 and output pipe 2, considering the complex layout of the pipelines within the pumping station, customized elbows and tees are used to ensure smooth connection between the input pipe 5 and output pipe 2 and other pipelines within the pumping station. When installing the input pipe 5 and output pipe 2, according to the site pipeline layout, they are connected to external pipelines via connecting flanges. When installing the gearbox 3 and drive motor 4, a connection is made between the gearbox 3 and the top of the casing 1. In addition, damping pads are added between the drive motor 4 and the top of the gearbox 3 to reduce vibration during operation. Heat dissipation fins are installed on one side wall of the gearbox 3 for heat dissipation. An oil inlet and outlet are provided on the gearbox 3 for easy adding and changing of gear oil. When installing the internal rotating parts, for the installation of the first rotating shaft 11 and the first rotating roller 6, an appropriate amount of grease is applied to the rotatable connection between the first rotating shaft 11 and the bottom inner wall of the housing 1, and to the connection with the output end of the gearbox 3, to ensure smooth rotation. When installing the crushing teeth 9, ... Use special tools to ensure that each crushing tooth 9 is firmly installed and evenly spaced. For the installation of the second rotating shaft 12, the second rotating roller 8, the first tearing tooth 7 and the second tearing tooth 10, apply grease to the connection of the second rotating shaft 12. When installing the first tearing tooth 7 and the second tearing tooth 10, carefully adjust their positions so that the first tearing teeth 7 on the two second rotating rollers 8 are installed in a staggered manner. After installation, the drive motor 4 can be started through the PLC controller. In the initial stage of operation, closely observe the operation of each component and check for any abnormal noise or vibration. If any is found, stop the machine in time for inspection and adjustment. During operation, large particles of impurities enter the housing 1 through the input pipe 5. The gearbox 3 can make the two first rotating rollers 6 rotate in opposite directions and make the two second rotating rollers 8 rotate in the same direction. Thus, they are crushed by the two first rotating rollers 6 that rotate in opposite directions and have the crushing teeth 9 installed in a staggered manner. Fibrous impurities are crushed by the two second rotating rollers 8 that rotate in the same direction and have the first tearing teeth 7 installed in a staggered manner, together with the second tearing teeth 10 installed on the inner wall of the housing 1. Finally, they are discharged from the output pipe 2.

[0022] Implementation effect: The large particle crushing mechanism includes two first rotating rollers 6 with first rotating shafts 11 installed. The crushing teeth 9 evenly distributed on the outer ring of the first rotating rollers 6 are installed in a staggered manner. The two first rotating rollers 6 rotate in opposite directions under the drive of the gearbox 3. When large particle impurities enter the housing 1 from the input pipe 5, the staggered and reverse-rotating crushing teeth 9 can fully and effectively crush the large particle impurities, avoid large particle impurities clogging the sewage pump pipe, and ensure the normal operation of the sewage pump.

[0023] Through the fiber crushing mechanism, two second rotating rollers 8 equipped with second rotating shafts 12 have first tearing teeth 7 evenly distributed on their outer rings, which are installed in a staggered manner and cooperate with the second tearing teeth 10 installed on the side wall of the housing 1. The two second rotating rollers 8 rotate in the same direction under the drive of the gearbox 3, which can powerfully tear and crush fibrous impurities, effectively handle fibrous impurities, improve the anti-clogging ability of the sewage pump pipeline, and prevent the sewage pump pipeline from being blocked.

[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.
