Description

Technical Field

[0001] This utility model relates to the technical field of airlift sand suction bridge sand discharge pipe, specifically a self-cleaning device for airlift sand suction bridge sand discharge pipe. Background Technology

[0002] Waterworks and sewage treatment plants both have grit chambers, many of which are horizontal flow grit chambers or aerated grit chambers. Regardless of the type of grit chamber, it is necessary to remove the fine sand and small debris deposited in the water from the chamber. Currently used equipment includes sand suction bridges with sand suction pumps for sand removal or sand discharge pipes for direct sand removal.

[0003] Existing air-lift sand-draining bridges and sand-discharging pipelines leave a certain amount of silt or slurry adhering to the inside of the pipes when discharging slurry or sediment. Cleaning requires manual flushing with a high-pressure water gun, which is labor-intensive and inconvenient. Adding a backflushing pipe below the main pipe requires even greater pressure to flush the water to the top of the pipe due to its length, which is energy-intensive. Furthermore, the overall length of the sand-draining pipe is fixed, making it difficult to adjust flexibly according to different sand-draining conditions and locations.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed a self-cleaning device for the air-lift sand suction bridge sand discharge pipeline. Utility Model Content

[0005] The purpose of this invention is to provide a self-cleaning device for air-lift sand suction bridge sand discharge pipelines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning device for a sand-lifting and sand-absorbing bridge pipeline, comprising a main pipe, a secondary pipe slidably inserted into the interior of the main pipe, a sealing ring fixedly installed on the upper side of the outer surface of the secondary pipe, a scraper fixedly connected to the upper surface of the sealing ring, an electrically controlled rail fixedly installed on the right side of the outer surface of the main pipe, an electrically controlled slider slidably installed on the surface of the electrically controlled rail, a connecting rod fixedly installed at the lower end of the electrically controlled slider, and a ring plate fixedly connected to the bottom end of the connecting rod.

[0007] Preferably, the sealing ring slides tightly against the inner surface of the main pipe, and the scraper also slides tightly against the inner surface of the main pipe, and the ring plate is fixedly connected to the lower side of the outer surface of the secondary pipe.

[0008] Preferably, a booster pump is fixedly installed on the left side of the upper surface of the ring plate, and a water supply hose is connected to the left side of the booster pump.

[0009] Preferably, a backflushing nozzle ring is embedded in the lower inner wall of the secondary pipe, and the backflushing nozzle ring is connected to the booster pump via a pipe passing through the secondary pipe.

[0010] Preferably, the backflush nozzle ring consists of a hollow ring and high-pressure nozzles evenly distributed on the inner side of the ring body, and the spraying range of the backflush nozzle ring can cover the entire secondary pipe and the upper part of the secondary pipe.

[0011] Preferably, a flange is fixedly installed on the upper side of the outer surface of the main pipe, and the flange is used to connect the main pipe to other pipes.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of an electrically controlled track, an electrically controlled slider, a ring plate, a connecting rod, a sealing ring, and a scraper, allows the electrically controlled slider to slide up and down on the surface of the electrically controlled track. This, in turn, pulls the secondary pipe inside the main pipe to extend or retract via the connecting rod and the ring plate, thus allowing for length adjustment according to actual usage requirements. The sealing ring prevents mortar from leaking through the joint between the secondary pipe and the main pipe. Therefore, the mortar only adheres to the inside of the secondary pipe and the part above the secondary pipe inside the main pipe. After discharge, the upward movement of the electrically controlled slider can also drive the secondary pipe to rise, allowing the scraper to slide against the inside of the main pipe, effectively removing the mortar adhering to the inner surface of the main pipe and retracting the pipe, facilitating the overall transportation of the equipment. 2. This utility model, through the configuration of a booster pump, a water supply hose, and a backwash nozzle ring, allows the booster pump to draw water from the water supply hose and spray it out through the backwash nozzle ring. This enables high-pressure flushing of the interior of the secondary pipe, and some of the high-pressure flushing water also sprays onto the upper part of the secondary pipe, i.e., the interior of the main pipe. Although the water pressure at the top is reduced, the water flow can still soften the mortar adhering to the inner surface of the main pipe, thus allowing the scraper to more effectively scrape off the mortar residue inside the main pipe. As the secondary pipe rises, the water flow can thoroughly and completely spray and cover the interior of the main pipe. This method only requires a certain pressure output to clean the entire pipe, and does not require the booster pump to output excessive pressure, thereby reducing power output and saving energy. The scraped mortar can also be immediately discharged downward with the water flow, preventing the accumulation of residual mortar. Attached Figure Description

[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] like Figures 1-3 As shown, the self-cleaning device for the sand discharge pipeline of the air-lift sand suction bridge includes a main pipe 1. A secondary pipe 2 is slidably inserted into the inside of the main pipe 1. A sealing ring 7 is fixedly installed on the upper side of the outer surface of the secondary pipe 2. A scraper 8 is fixedly connected to the upper surface of the sealing ring 7. An electrically controlled rail 3 is fixedly installed on the right side of the outer surface of the main pipe 1. An electrically controlled slider 4 is slidably installed on the surface of the electrically controlled rail 3. A connecting rod 6 is fixedly installed at the lower end of the electrically controlled slider 4. A ring plate 5 is fixedly connected to the bottom end of the connecting rod 6. The sealing ring 7 slides tightly against the inner surface of the main pipe 1, and the scraper 8 also slides tightly against the inner surface of the main pipe 1. The ring plate 5 is fixedly connected to the lower side of the outer surface of the secondary pipe 2.

[0017] By adopting the above technical solution, the electric slider 4 can slide up and down on the surface of the electric track 3, thereby pulling the secondary pipe 2 to extend or retract inside the main pipe 1 through the connecting rod 6 and the ring plate 5, so that the length of the pipeline can be adjusted according to the actual needs of use; The sealing ring 7 can prevent mortar from leaking through the joint between the secondary pipe 2 and the main pipe 1. Therefore, no matter how much the secondary pipe 2 shrinks or extends, the mortar will only stick to the inside of the secondary pipe 2 and the part of the secondary pipe 2 above the main pipe 1. After discharge, the upward movement of the electric control slider 4 can drive the secondary pipe 2 to rise, so that the scraper 8 slides against the inside of the main pipe 1, thereby effectively removing the mortar adhering to the inner surface of the main pipe 1 and shrinking the pipe to facilitate the overall transportation of the equipment.

[0018] Furthermore, a booster pump 9 is fixedly installed on the left side of the upper surface of the ring plate 5, and a water supply hose 10 is connected to the left side of the surface of the booster pump 9.

[0019] By adopting the above technical solution, the booster pump 9 can draw water from the water supply hose 10. The flexibility of the water supply hose 10 allows the secondary pipe 2 to be adjusted arbitrarily without affecting the water supply hose 10 to the water source.

[0020] Furthermore, a backflush nozzle ring 11 is embedded in the lower inner wall of the secondary pipe 2, and the backflush nozzle ring 11 is connected to the booster pump 9 via a pipe passing through the secondary pipe 2. The backflush nozzle ring 11 consists of a hollow ring and high-pressure nozzles evenly distributed on the inner side of the ring body. The spraying range of the backflush nozzle ring 11 can cover the entire secondary pipe 2 and the upper part of the secondary pipe 2.

[0021] By adopting the above technical solution, the booster pump 9 uses the water supply hose 10 to draw water from the source and sprays it out through the backwash nozzle ring 11, which can perform high-pressure flushing on the inside of the secondary pipe 2 to ensure the cleanliness of the inside of the secondary pipe 2. Some of the high-pressure flushing water will also spray onto the upper part of the secondary pipe 2, that is, the inside of the main pipe 1. Although the water pressure at the top will be reduced, the water flow can still soften the mortar adhering to the inner surface of the main pipe 1, so that the scraper 8 can more effectively scrape off the mortar residue inside the main pipe 1. After scraping, it can also be discharged downward with the water flow to avoid the accumulation of residual mortar. Furthermore, as the secondary pipe 2 rises, the water flow can thoroughly and completely spray and cover the interior of the main pipe 1.

[0022] Working Principle: When using this air-lift sand-suction bridge sand discharge pipeline self-cleaning device, firstly, the main pipe 1 is connected to the entire working pipeline via flange 12. Then, the electric control slider 4 can slide up and down on the surface of the electric control track 3, thereby pulling the secondary pipe 2 inside the main pipe 1 through the connecting rod 6 and ring plate 5 to extend or retract. This allows for adjustment according to the actual length requirements, adjusting the sand discharge pipe to a suitable discharge length before sand discharge can begin. During the sand discharge process, the sealing ring 7 prevents mortar from leaking through the joint between the secondary pipe 2 and the main pipe 1. Therefore, the mortar only adheres to the inside of the secondary pipe 2 and the part of the secondary pipe 2 above the main pipe 1. After discharge, the pressure pump 9 uses the water supply hose 10 to draw water, which is then passed through the backflushing nozzle. The water jet from ring 11 sprays out, providing high-pressure flushing to the inside of the secondary pipe 2. Some of the high-pressure flushing water also sprays onto the upper part of the secondary pipe 2, i.e., the inside of the main pipe 1. Although the water pressure at the top is reduced, the water flow can still soften the mortar adhering to the inner surface of the main pipe 1. At the same time, the upward movement of the electrically controlled slider 4 drives the secondary pipe 2 to rise, and the scraper 8 slides against the inside of the main pipe 1, thereby effectively removing the mortar adhering to the inner surface of the main pipe 1. As the secondary pipe 2 rises, the water flow can thoroughly and completely spray and cover the inside of the main pipe 1, thoroughly self-cleaning the entire sand discharge pipe. After cleaning, the secondary pipe 2 and the main pipe 1 are also retracted, facilitating the transportation of the entire equipment. This is the working principle of the self-cleaning device for the air-lift sand suction bridge sand discharge pipeline.
