An auxiliary filtration device

Abstract

This utility model relates to the field of building drainage technology, specifically an auxiliary filtration device, including a main pipe and a first and second connecting pipe fixedly connected to both sides of the main pipe. The upper flange of the main pipe is connected to a flange cover, and the upper end of the flange cover is fixed with a handle. The purpose of this utility model is to provide a device that, when used, is connected to a water pipe after assembly. The first connecting pipe is the inlet end, and the second connecting pipe is the outlet end. When the water to be filtered enters the device through the first connecting pipe, the straight rod simultaneously drives the second filter element to rotate. The second filter element first filters the water flow, and then the water flow flows through the first filter element for secondary filtration. This design improves the filtration efficiency through two layers of filter elements, and the rotation of the second filter element driven by the water flow increases the contact area between the water flow and the filter element. This not only reduces the wear of the first filter element caused by water flow impact and increases the service life of the device, but also improves the filtration effect to a certain extent.

Description

Technical Field

[0001] This utility model relates to the field of building drainage technology, specifically to an auxiliary filtration device. Background Technology

[0002] Wastewater treatment refers to 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, and is increasingly entering the daily lives of ordinary people. However, most existing drainage filtration devices are single-layer filters with poor filtration effects. Moreover, under the impact of high-pressure water flow, the filter element is severely worn by the metal impurities in the water flow, resulting in a shortened service life of the filter element. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary filtration device, comprising a main pipe and a first connecting pipe and a second connecting pipe symmetrically arranged on both sides of the main pipe. A flange cover is connected to the upper flange of the main pipe, a handle is fixed to the upper end of the flange cover, a connector is fixed to the lower end of the flange cover, a first filter element is fixed to the lower end of the connector, a fixing member is provided at the center of the flange cover, a rotating shaft is rotatably connected to the lower end of the fixing member, a second filter element is provided at the lower end of the rotating shaft, a first limiting block is fixed to the inner side of the first filter element, a threaded rod is rotatably connected to one end of the first limiting block, a sliding block is slidably connected to the outer side of the threaded rod, a scraper is fixed to the outer side of the sliding block, a limiting rod is fixed to one side of the first limiting block, a second limiting block is provided to one end of the limiting rod, a straight rod is fixedly connected to one end of the threaded rod, and multiple sets of fan blades are provided to the outer side of the straight rod.

[0010] Preferably, the second filter element has a notch in the middle, and the opening is directly opposite the center of the first connecting pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. When using this device, connect the assembled device to the water pipe. The first connector is the water inlet, and the second connector is the water outlet. When the water to be filtered enters the device through the first connector, the straight rod simultaneously drives the second filter element to rotate. The second filter element will first filter the water flow, and then the water flow will flow through the first filter element for secondary filtration. This design improves the filtration efficiency through two layers of filter elements, and the rotation of the second filter element driven by the water flow increases the contact area between the water flow and the filter element. This not only reduces the wear of the first filter element caused by water flow impact and increases the service life of the device, but also improves the filtration effect to a certain extent.

[0012] 2. When the water flow drives the fan blades to rotate, the fan blades drive the straight rod to rotate, and the straight rod drives the threaded rod to rotate synchronously. The rotation of the threaded rod drives the sliding block to slide on the threaded rod under the restriction of the second limiting block and the first limiting block. The sliding block drives the scraper to slide synchronously to scrape off the attached impurities on the inner wall of the second filter element. This design not only reduces the cleaning difficulty for the cleaning personnel when cleaning the filter element, but also reduces the number of cleanings, saving manpower and material resources to a certain extent.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0016] Please see Figures 1 to 5 This utility model provides an auxiliary filtration device, including a main pipe 1 and a first connecting pipe 2 and a second connecting pipe 3 symmetrically arranged on both sides of the main pipe 1. A flange cover 4 is connected to the upper flange of the main pipe 1. A handle 5 is fixed to the upper end of the flange cover 4. A connector 7 is fixed to the lower end of the flange cover 4. A first filter element 6 is fixed to the lower end of the connector 7. A fixing member 8 is provided at the center of the flange cover 4. A rotating shaft 9 is rotatably connected to the lower end of the fixing member 8. A second filter element 10 is provided at the lower end of the rotating shaft 9. A first limiting block 14 is fixed to the inner side of the first filter element 6. A threaded rod 13 is rotatably connected to one end of the first limiting block 14. A sliding block 17 is slidably connected to the outer side of the threaded rod 13. A scraper 15 is fixed to the outer side of the sliding block 17. A limiting rod 18 is fixed to one side of the first limiting block 14. A second limiting block 16 is provided at one end of the limiting rod 18. A straight rod 11 is fixedly connected to one end of the threaded rod 13. Multiple sets of fan blades 12 are provided on the outer side of the straight rod 11.

[0017] When using this device, connect the assembled device to the water pipe. The first connector 2 is the water inlet, and the second connector 3 is the water outlet. When the water to be filtered enters the device through the first connector 2, the water flow into the second filter element 10 causes the fan blade 12 to rotate. The rotation of the fan blade 12 causes the straight rod 11 to rotate, and the straight rod 11 simultaneously drives the second filter element 10 to rotate. The second filter element 10 will first filter the water flow, and then the water flow will flow through the first filter element 6 for secondary filtration. This design improves the filtration efficiency through two layers of filter elements, and the rotation of the second filter element 10 caused by the water flow increases the contact area between the water flow and the filter element. This not only reduces the wear of the first filter element 6 caused by the water flow impact and increases the service life of the device, but also improves the filtration effect to a certain extent.

[0018] When the water flow drives the fan blade 12 to rotate, the fan blade 12 drives the straight rod 11 to rotate, and the straight rod 11 drives the threaded rod 13 to rotate synchronously. The rotation of the threaded rod 13 drives the sliding block 17 to slide on the threaded rod 13 under the restriction of the second limiting block 16 and the first limiting block 14. The sliding block 17 drives the scraper 15 to slide synchronously to scrape off the attached impurities on the inner wall of the second filter element 10. This design not only reduces the cleaning difficulty for the cleaning personnel when cleaning the filter element, but also reduces the number of cleanings, saving manpower and material resources to a certain extent.

[0019] In an optional embodiment, an O-ring 19 is provided at one end of the main pipe 1, and flange rings are provided for both the first connecting pipe 2 and the second connecting pipe 3.

[0020] It should be noted that the O-ring 19 and flange ring ensure the sealing of the device.

[0021] In an optional embodiment, one end of the straight rod 11 is fixedly connected to the second filter element 10, and the other end of the straight rod 11 is fixedly connected to the threaded rod 13.

[0022] It should be noted that when the fan blade 12 rotates, it ensures the synchronous rotation of the straight rod 11, the threaded rod 13, and the second filter element 10.

[0023] In an optional embodiment, the outer diameter of the scraper 15 is slightly smaller than the inner diameter of the second filter element 10, and the scraper 15 is made of silicone.

[0024] It should be noted that the scraper 15 can slide up and down inside the second filter element 10 to scrape off the attached impurities.

[0025] In an optional embodiment, the lower end of the second filter element 10 is open, and the pore size of the filter pores on the second filter element 10 is slightly larger than that on the first filter element 6.

[0026] It should be noted that the second filter element 10 performs the first filtration, and the first filter element 6 performs the second filtration. The second filter element 10 discharges impurities through the opening at the bottom.

[0027] In an optional embodiment, a bearing is provided on the inner side of the second limiting block 16, and a hole is provided on the sliding block 17, the hole having the same diameter as the limiting rod 18.

[0028] It should be noted that the bearing inside the second limiting block 16 can ensure that the straight rod 11 rotates normally, and the hole provided on the sliding block 17 can prevent the sliding block 17 from rotating together with the threaded rod 13 under the restriction of the limiting rod 18.

[0029] In an optional embodiment, the second filter element 10 has a notch in the middle, and the opening is directly opposite the center of the first connector 2.

[0030] It should be noted that the opening directly opposite the center of the first connecting pipe 2 allows water to flow directly through the fan blade 12, providing sufficient power for the fan blade 12 to rotate.

[0031] Working principle: When using this device, connect the assembled device to the water pipe. The first connector 2 is the water inlet and the second connector 3 is the water outlet. When the water to be filtered enters the device through the first connector 2, the water flow into the second filter element 10 causes the fan blade 12 to rotate. The rotation of the fan blade 12 causes the straight rod 11 to rotate, and the straight rod 11 simultaneously causes the second filter element 10 to rotate. The second filter element 10 will first filter the water flow, and then the water flow will flow through the first filter element 6 for secondary filtration.

[0032] When the water flow drives the fan blade 12 to rotate, the fan blade 12 drives the straight rod 11 to rotate, and the straight rod 11 drives the threaded rod 13 to rotate synchronously. The rotation of the threaded rod 13 drives the sliding block 17 to slide on the threaded rod 13 under the restriction of the second limiting block 16 and the first limiting block 14. The sliding block 17 drives the scraper 15 to slide synchronously to scrape off the attached impurities on the inner wall of the second filter element 10.

[0033] 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.
