Abstract
Description
Technical Field
[0001] This invention relates to the field of water supply facilities technology, specifically to a filtration and sewage discharge device for water supply networks. Background Technology
[0002] As the core artery of the urban water supply system, the water supply network bears the important mission of closely connecting natural water sources with water treatment plants. During the process of drawing water from the source, the network system constructs the first line of defense through multi-stage filtration devices. These facilities act like precise "water sieves," effectively intercepting larger impurities such as dead leaves, plastic fragments, and other debris mixed in the water, preventing them from entering the pipes and causing siltation.
[0003] A search of patent number "CN222238979U" reveals a "Filtering and Sewage Discharge Device for Water Supply Networks," which includes a filter box. The filter box has an inlet port on its top left edge that is fixedly connected to an inlet pipe, and an outlet port on its bottom left edge that is fixedly connected to an outlet pipe. A rotating plate is movably installed on the inner wall of the filter box. The top of the rotating plate is connected to the filter box via a rotating baffle structure. Two symmetrically arranged insertion channels are provided on the rotating plate, each containing a filter screen with an I-shaped vertical cross-section. Through the rotating baffle structure, starting the motor causes the rotating cylinder to rotate the rotating plate, the two small baffles, and the large baffle 180 degrees, thereby swapping the positions of the two filter screens. This allows the filter screen on the right side to be replaced when the left side needs replacement.
[0004] Although the above-mentioned device makes it easy to replace the filter screen, impurities and debris can still clog the filter screen during use, and the entire water supply network can easily become blocked if the filter screen is not replaced in time. Summary of the Invention

The interior of the air inlet and the air outlet are respectively hinged with a first one-way door and a second one-way door. A sliding sleeve is provided through the bottom of the housing. A movable column is slidably connected to the inner wall of the sliding sleeve. A piston is bolted to the top of the movable column and is slidably connected to the inner wall of the housing. A roller is bolted to the bottom of the movable column. An elliptical wheel is also fixed to the surface of the transmission rod. Several compression springs are fixed to the upper part of the housing, and the bottom ends of the compression springs are in contact with the piston. One end of the air outlet is connected to a delivery pipe, and the other end of the delivery pipe is connected to an air nozzle.
[0011] Preferably, the first one-way door can open towards the inside of the enclosure, and the second one-way door can open away from the inside of the enclosure.
[0012] Preferably, the number of compression springs is four, and they are located at the four upper corners inside the housing.
[0013] Preferably, the surface of the transverse channel is further bolted with several fixing sleeves, and the fixing sleeves are fitted onto the surface of the conveying pipeline.
[0014] Preferably, a support platform is bolted to one side of the bracket, and a collection cylinder is provided on the top of the support platform.
[0015] Preferably, the surface of the side plate is also rotatably connected with several auxiliary rollers.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0020] 1. This invention uses a drive motor to rotate the transmission rod and rotating column, causing the rotating frame to move the filter screen in a circular motion. The filter screen filters water. At the same time, the transmission rod drives the active rod and active roller to rotate, causing the transmission belt to move the scraper on the surface, pushing impurities and debris on the filter screen to the outside of the device, thus achieving the effect of removing impurities and debris. No manual cleaning of the filter screen is required, avoiding clogging and making it more convenient to use.
[0021] 2. The transmission rod drives the elliptical wheel to rotate, and in conjunction with the use of the compression spring, the movable column and piston reciprocate up and down. This, in conjunction with the first and second one-way doors, generates compressed gas that is transported into the conveying pipeline. Finally, the gas is discharged through the air outlet to clean the scraper and the transmission belt. Attached Figure Description

Detailed Implementation
[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] Please see Figures 1-9As shown, a filtration and sewage discharge device for a water supply network includes a barrel 1 and a support 2. The support 2 is bolted to the bottom of the barrel 1 to support the barrel 1. An inlet pipe 3 is connected to the top of the barrel 1 for water to enter, and an outlet pipe 4 is connected to the bottom of the barrel 1 to discharge the filtered water inside the barrel 1. A water pump 5 is connected to the other end of the outlet pipe 4. When the water pump 5 is connected to a water supply pipeline and turned on, the water passing through the outlet pipe 4 can be transported. An inner cylinder 7 is fixed inside the barrel 1. The inner cylinder 7 is fixed to the inner wall of the barrel 1 by a connecting rod. A rotating column 8 is rotatably connected inside the inner cylinder 7. The top of the rotating column 8 extends through to the top of the inner cylinder 7 and is bolted to a rotating frame 9. A filter screen 10 is bolted to the surface of the rotating frame 9. The rotating column 8 is rotatably connected to the inner cylinder 7 at the penetration point. A drive motor 12 is also bolted to one side of the barrel 1. A transmission rod 11 is installed through one side of the surface of the barrel 1. A transmission rod 11 passes through the barrel body 1 and the inner cylinder 7 respectively. The transmission rod 11 is rotatably connected to the passage of the barrel body 1 and the inner cylinder 7. One end of the transmission rod 11 is fixed to the output shaft of the drive motor 12. The other end of the transmission rod 11 is connected to the rotating column 8 through a bevel gear. A through groove 6 is opened on one side of the barrel body 1. Side plates 13 are bolted to both sides of the inner wall of the through groove 6. A drive roller 15 and a driven roller 18 are rotatably connected to the surface of the side plates 13 respectively. A transmission belt 16 is provided on the surface of the drive roller 15 and the driven roller 18. A scraper 17 is fixed on the surface of the transmission belt 16. Both the transmission belt 16 and the scraper 17 are made of rubber. Several auxiliary rollers 19 are also rotatably connected to the surface of the side plates 13 for supporting the transmission belt 16. A transverse channel 21 is also bolted to one side of the barrel body 1. An air blowing mechanism 20 is also provided on the outside of the barrel body 1. A drive rod 14 is also bolted to one side of the drive roller 15. The drive rod 14 and the transmission rod 11 are connected by a belt drive.
[0034] During operation, water flows through inlet pipe 3 and falls onto the surface of filter screen 10. Simultaneously, drive motor 12 is activated, and its output shaft drives transmission rod 11 to rotate. Transmission rod 11 drives rotating column 8 to rotate via bevel gear. Rotating column 8 drives rotating frame 9 to rotate counterclockwise, thereby causing filter screen 10 to move in a circular motion. Filter screen 10 intercepts impurities in the water, allowing water to pass through filter screen 10 and flow through the bottom of barrel 1 to the inside of outlet pipe 4. Then, water pump 5 is activated to discharge the filtered water into the subsequent pipeline. At the same time, impurities follow filter screen 10 to move below scraper 17. Transmission rod 11 drives drive rod 14 to rotate via belt. Drive rod 14 drives drive roller 15 to rotate clockwise, thereby moving scraper 17 and pushing impurities on the surface of filter screen 10 toward the transverse channel 21.
[0035] A support platform 22 is bolted to one side of the bracket 2. A collection cylinder 23 is provided on the top of the support platform 22. The scraper 17 pushes the impurities to fall from the surface of the transverse channel 21 and into the collection cylinder 23. The support platform 22 is used to support the collection cylinder 23. The inner diameter of the collection cylinder 23 is larger than the width of the transverse channel 21 to prevent the cleaned impurities from falling into the outside of the collection cylinder 23.
[0036] The air blowing mechanism 20 includes a housing 201, an air inlet 202, and an air outlet 203. The housing 201 is bolted to the surface of the barrel 1. The air inlet 202 and the air outlet 203 are respectively connected to both sides of the housing 201. A first one-way door 204 and a second one-way door 205 are respectively hinged inside the air inlet 202 and the air outlet 203. The first one-way door 204 can only be opened towards the inside of the housing 201, and the second one-way door 205 can only be opened away from the inside of the housing 201. A sliding sleeve 208 is provided through the bottom of the housing 201. A movable column 209 is slidably connected to the inner wall of the sliding sleeve 208. A piston 207 is bolted to the top of the movable column 209, and the piston 207 is slidably connected to the inner wall of the housing 201. A roller 2 is bolted to the bottom of the movable column 209. 10. An elliptical wheel 211 is fixed to the surface of the transmission rod 11. Several compression springs 206 are fixed to the upper part of the housing 201, and the bottom end of the compression springs 206 is in contact with the piston 207. There are four compression springs 206, which are located at the four corners of the upper part of the housing 201. Under the action of the compression springs 206, the piston 207 and the movable column 209 are given a downward reaction force, so that the roller 210 is in contact with the surface of the elliptical wheel 211. One end of the air outlet 203 is connected to the conveying pipe 212, and the other end of the conveying pipe 212 is connected to the air nozzle 213. Several fixing sleeves 24 are also bolted to the surface of the transverse channel 21, and the fixing sleeves 24 are fitted on the surface of the conveying pipe 212 for auxiliary support and fixation of the conveying pipe 212.
[0037] During the rotation of the transmission rod 11, it drives the elliptical wheel 211 on its surface to rotate as well. Simultaneously, the long and short radius ends of the elliptical wheel 211 alternately contact the roller 210, causing the movable column 209 and piston 207 to reciprocate up and down. As the piston 207 descends, the volume of the space above the inside of the housing 201 increases, and the pressure decreases. External air pushes open the first one-way door 204 and enters the inside of the housing 201 through the air inlet 202. At this time, the second one-way door 205 cannot open into the inside of the housing 201. During the upward movement of the piston 207, the inside of the housing 201... The space above decreases, the internal air pressure increases, and the air enters the outlet 203, opening the second one-way door 205 and entering the interior of the conveying pipe 212. The first one-way door 204 cannot be opened to the outside of the box 201, and the air will not be discharged through the inlet 202. This process is repeated to achieve gas delivery. The compressed gas is discharged through the outlet 213 after passing through the conveying pipe 212 and blown onto the surface of the transmission belt 16 and scraper 17 to prevent impurities from adhering to the surface of the transmission belt 16 and scraper 17. It should be noted that the pressure of water entering through the inlet pipe 3 should not be too high to prevent water from splashing out from the through groove 6.
[0038] 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 thereof 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.
