Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a multi-stage filtration device that prevents pipe blockage and facilitates sludge removal. Background Technology
[0002] In sewage treatment plants, water supply plants, industrial factories, and daily life, various production and domestic pipe blockages are common problems. The main causes of pipe blockage include sediments and foreign objects affecting the pipe's water flow capacity. Sediments such as scale, grease, and debris gradually accumulate, causing the pipes to narrow; foreign objects such as hair, paper scraps, food residue, and fabric may accidentally enter the pipes; and improper design of indoor drainage pipes and sanitary ware pipes in some older buildings can also obstruct water flow and lead to blockages.
[0003] Blockages in the pipes of water treatment plants and industrial factories can affect the normal operation of the equipment and even cause backflow of waste liquid, resulting in environmental pollution incidents. Similarly, blockages in household drainage pipes and sanitary ware pipes can cause sewage to overflow from bathroom drains and toilets, preventing proper sewage discharge and causing foul odors, severely impacting residents' daily lives. Although water treatment plants and industrial factories may have bar screens for cleaning waste, small-diameter filter pipes, waste liquid pipes, and sludge-water separation pipes can still become clogged due to the long-term accumulation of small foreign objects.
[0004] In daily life, floor drains and other waste-skimming devices are commonly found in homes. However, floor drains, being external, have drawbacks such as being unclean, unhygienic, and prone to backflow of odors. Furthermore, floor drains can become clogged over time. Overall, traditional pipe filtration and waste-skimming methods suffer from drawbacks such as frequent cleaning, odor emission, filter clogging, inconvenient cleaning, incomplete waste separation, and eventual clogging even after long-term use. Utility Model Content
[0005] The purpose of this invention is to address the problems existing in the prior art by providing a multi-stage filtration device that prevents pipe blockage and facilitates slag removal. This device can be directly installed on the pipe according to different pipe diameters and different usage scenarios. It adopts a multi-stage filtration method to isolate and retain blockages of different types and sizes, while taking into account the advantages of easy slag removal, good sealing, and good odor isolation, and can effectively prevent pipe blockage.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] A multi-stage filtration device for preventing pipe blockage and facilitating sludge removal includes three detachably connected filter units. The three filter units are connected at their ends and threadedly connected to an inlet telescopic straight pipe. The end of the inlet telescopic straight pipe has a connecting groove. A corrugated telescopic pipe is connected to the middle of the inlet telescopic straight pipe. The filter units are partially connected to a back plate and a side plate. The side plate has a hinge, allowing the back plate to rotate around the hinge. Each filter unit includes a rotating filter tube and a filter mesh. Along the direction away from the inlet telescopic straight pipe, the mesh size of the three filter meshes decreases sequentially. The three filter units are connected at their tails and threadedly connected to an outlet straight pipe.
[0008] Furthermore, the three filter units are sequentially snapped together or threaded together.
[0009] Furthermore, all three filter units are equipped with handles.
[0010] Furthermore, a leak-proof sealing rubber ring is provided between the three filter units.
[0011] Furthermore, the filter mesh is made of stainless steel.

[0020] The following detailed description illustrates the specific implementation method:
[0021] like Figure 1 and Figure 2 As shown, a multi-stage filtration device for preventing pipe blockage and facilitating sludge removal includes three detachably connected filter units 4. After the three filter units 4 are connected, an inlet telescopic straight pipe 1 is threadedly connected to their ends. The inlet telescopic straight pipe 1 has a connecting groove 2 at its end. A corrugated telescopic pipe 3 is connected to the middle of the inlet telescopic straight pipe 1. The filter units 4 are partially connected to a back plate 5 and a side plate 6. A hinge 7 is provided on the side plate 6, allowing the back plate 5 to rotate around the hinge 7. Each filter unit 4 includes a rotating filter tube 8 and a filter mesh 9. The mesh size of the three filter meshes 9 decreases sequentially along the direction away from the inlet telescopic straight pipe 1. After the three filter units 4 are connected, an outlet straight pipe 10 is threadedly connected to their tail ends.
[0022] After the device in the above embodiment is installed, it can be used by turning on water. The water flows through three filtration units in sequence: primary, secondary, and tertiary. Impurities of different particle sizes are intercepted by meshes with coarse, medium, and fine pore sizes, respectively. When the amount of debris nearly fills the filtration unit, the filtration unit can be rotated out for cleaning. After cleaning, the filtration unit can be rotated back to its original position to continue functioning.
[0023] Meanwhile, the device is equipped with threaded connection ports at the inlet and outlet, which can be matched with detachable threaded sleeves of different diameters. This allows for free combination of devices of various sizes and pipes of various diameters, providing strong flexibility to ensure adaptability to slag interception and cleaning operations under various scenarios and media.
[0024] In some embodiments, based on the above embodiments, in order to facilitate flexible cleaning of the three different filter units, the three filter units 4 are sequentially snapped or threaded together. In this way, when the filter unit at the front end needs to be cleaned, it is only necessary to rotate the rotating filter tube 8 of the filter unit at the front end and take it out to clean the garbage and impurities intercepted by the filter mesh 9. The cleaning is more flexible and the cleaning efficiency is higher.
[0025] In some embodiments, based on the above embodiments, to facilitate the removal and installation of the filter units, each of the three filter units 4 is provided with a handle 11. When the amount of debris intercepted is nearly full, the filter unit can be rotated out using the handle 11 for cleaning. After cleaning, the filter unit can be rotated back to its original position to continue functioning.
[0026] In some embodiments, in order to ensure a more airtight connection between the three filter units during use and prevent leakage, a leak-proof sealing rubber ring 12 is provided between the three filter units in this embodiment.
[0027] In some embodiments, in order to improve the service life of the filter mesh 9 and prevent the filter mesh 9 from rusting and affecting the filtration effect, the filter mesh in this embodiment is made of stainless steel.
[0028] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
