Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, specifically to a municipal water supply and drainage sewage treatment equipment that facilitates sewage purification. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering.

[0003] Currently, municipal water supply and drainage sewage treatment equipment on the market cannot effectively clean larger particles of debris in sewage. This causes debris to clog the filter inside the equipment, requiring periodic shutdowns for cleaning after the equipment has been running for a period of time, thus reducing the efficiency of the sewage treatment equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a municipal water supply and drainage sewage treatment device that facilitates sewage purification, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A municipal water supply and drainage sewage treatment device for easy sewage purification includes a filter pipe, an inlet pipe fixedly connected to the inlet end of the filter pipe, a sludge discharge pipe fixedly connected to the bottom surface of the filter pipe, and a drain pipe fixedly connected to the side surface of the filter pipe.

[0007] A barrier filter screen is fixedly connected to the inner wall of the filter tube, and a filter screen cleaning component for cleaning the barrier filter screen is provided on the inner wall of the filter tube.

[0008] The filter cleaning assembly includes a central drive rod, an installation sleeve fixedly sleeved on the outer wall of the central drive rod, an auxiliary support ring fixedly connected to one end of the installation sleeve, a rotating scraper fixedly connected to the outer wall of the auxiliary support ring, the rotating scraper and the auxiliary support ring being movably connected to the inner wall of the filter tube, and a drive motor fixedly connected to one end of the central drive rod.

[0009] A further improvement of this utility model is that: a positioning ring is fixedly connected to one end of the central transmission rod, and a buffer conical plate is movably sleeved on the outer wall of the end of the central transmission rod away from the drive motor.

[0010] A further improvement of this utility model is that a buffer spring is fixedly connected to one side of the buffer conical plate.

[0011] A further improvement of this utility model is that a rubber gasket is fixedly connected to the side of the positioning ring near the buffer conical plate.

[0012] A further improvement of this utility model is that a control valve is provided on the outer wall of the slag discharge pipe.

[0013] A further improvement of this utility model is that the drive motor is fixedly connected to the end of the filter tube away from the water inlet pipe via a motor mounting base.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a municipal water supply and drainage sewage treatment equipment that facilitates sewage purification. By driving the central transmission rod, the mounting sleeve and the rotating scraper to rotate through the drive motor, the filter screen can be scraped and cleaned to remove impurities on the screen holes, thus preventing the filter screen from becoming clogged and improving the efficiency of sewage treatment. Hard bristles can be installed on the rotating scraper to further improve the cleaning effect.

[0016] 2. This utility model provides a municipal water supply and drainage sewage treatment equipment that facilitates sewage purification. When sewage enters the filter pipe from the inlet pipe, it impacts the buffer cone plate. The buffer cone plate slides on the central transmission rod and compresses the buffer spring to buffer the impact, which can avoid excessive impact on the inner wall of the filter pipe during sewage transportation and improve the service life of the filter pipe.

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] Example 1

[0025] like Figure 1-4 As shown, this utility model provides a municipal water supply and drainage sewage treatment equipment that facilitates sewage purification, including a filter pipe 1, an inlet pipe 2 fixedly connected to the inlet end of the filter pipe 1, a slag discharge pipe 4 fixedly connected to the bottom surface of the filter pipe 1, and a drain pipe 3 fixedly connected to the side surface of the filter pipe 1.

[0026] A barrier filter screen 6 is fixedly connected to the inner wall of the filter pipe 1, and a filter screen cleaning assembly for cleaning the barrier filter screen 6 is provided on the inner wall of the filter pipe 1. The barrier filter screen 6 can be made of stainless steel with a mesh size of 30, which can effectively filter large particulate wastewater impurities.

[0027] The filter cleaning assembly 7 includes a central drive rod 12. A mounting sleeve 13 is fixedly sleeved onto the outer wall of the central drive rod 12. An auxiliary support ring 10 is fixedly connected to one end of the mounting sleeve 13. A rotating scraper 9 is fixedly connected to the outer wall of the auxiliary support ring 10. Both the rotating scraper 9 and the auxiliary support ring 10 are movably connected to the inner wall of the filter tube 1. A drive motor 8 is fixedly connected to one end of the central drive rod 12 via a coupling.

[0028] The rotating scraper 9 is made of wear-resistant rubber and is arc-shaped, which can better fit the inner wall of the filter tube 1 and block the filter screen 6.

[0029] Example 2

[0030] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a positioning ring 15 is fixedly connected to one end of the central transmission rod 12, and a buffer conical plate 11 is movably sleeved on the outer wall of the end of the central transmission rod 12 away from the drive motor 8. The buffer conical plate 11 is made of plastic and is cone-shaped, which can better disperse the impact force of sewage.

[0031] A buffer spring 14 is fixedly connected to one side of the buffer cone plate 11. The buffer spring 14 is connected to one side of the buffer cone plate 11 via a hook, and its two ends are fixed to the buffer cone plate 11 and the positioning ring 15 via hooks respectively. A rubber gasket is attached to the side of the positioning ring 15 near the buffer cone plate 11, which serves to buffer and seal.

[0032] A rubber gasket is fixedly connected to the side of the positioning ring 15 near the buffer cone plate 11, and a control valve 5 is provided on the outer wall of the slag discharge pipe 4.

[0033] The drive motor 8 is fixedly connected to the end of the filter tube 1 away from the water inlet pipe 2 via the motor mounting bracket 16. The motor mounting bracket 16 is made of cast iron and is designed to effectively dampen vibration and fix the motor, preventing it from shaking during operation.

[0034] The working principle of this municipal water supply and drainage sewage treatment equipment, which facilitates sewage purification, will be explained in detail below.

[0035] like Figure 1-4 As shown, during use, the wastewater to be treated is transported to the filter pipe 1 through the inlet pipe 2. The wastewater transported to the filter pipe 1 will be transported to the drain pipe 3 under water pressure. During the transportation process, large particles of wastewater impurities are filtered out by the barrier filter screen 6.

[0036] Large particulate wastewater impurities will settle in the sludge discharge pipe 4 after a certain period of time after filtration. When sludge discharge is required, the control valve 5 is opened to discharge the sludge.

[0037] After prolonged filtration, the drive motor 8 is started by an external power source. The drive motor 8 then drives the mounting sleeve 13 to rotate inside the filter tube 1 via the central transmission rod 12. During rotation, the mounting sleeve 13 scrapes the filter screen 6 on the inner wall of the filter tube 1 via the rotating scraper 9, cleaning the screen holes on the filter screen 6 and preventing clogging, thus improving the efficiency of wastewater treatment. Hard bristles can also be installed on the rotating scraper 9 to further enhance the cleaning effect.

[0038] When sewage is transported from the inlet pipe 2 to the filter pipe 1, the sewage will impact the buffer cone plate 11. After being impacted, the buffer cone plate 11 will slide on the central transmission rod 12 and compress the buffer spring 14 to buffer the impact, thereby preventing the sewage from causing excessive impact on the inner wall of the filter pipe 1 during transportation and improving the service life of the filter pipe 1.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The present invention has been described in detail above, but modifications or improvements can be made based on it, which will be apparent to those skilled in the art. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
