Description

Technical Field

[0001] This utility model relates to the field of sludge collection technology, specifically to an automatic airlift sludge collection device. Background Technology

[0002] Sludge collection is an important part of the wastewater treatment process. Its purpose is to effectively separate sludge from the treated wastewater for further treatment or disposal. Sludge collection is not only a necessary step to ensure the normal operation of the wastewater treatment system, but also a key link to reduce environmental pollution and improve resource utilization efficiency. Common sludge collection methods include mechanical collection, air stripping collection, and flotation collection. Each method has its specific applicable scenarios and advantages and disadvantages. Air stripping collection devices use the buoyancy of air bubbles and the action of airflow to lift sludge from the water to the surface, and then use airflow to concentrate the sludge into the collection device.

[0003] When collecting sludge from large water tanks, conventional air-lift collection devices struggle to effectively collect sludge from all locations at the bottom of the tank, leaving some areas with significant sludge residue. This results in poor wastewater treatment and increases the workload of subsequent wastewater treatment processes. Furthermore, conventional air-lift collection devices often introduce sludge along with a large amount of water, leading to high sludge moisture content. Subsequent dewatering of the sludge requires considerable time and resources, reducing the efficiency of sludge treatment and causing resource waste. To address these issues, an automatic air-lift sludge collection device is proposed. Utility Model Content

[0004] To address the aforementioned technical problems, an automatic sludge airlift collection device is provided. This device solves the problem that current airlift collection devices struggle to effectively collect sludge from all locations at the bottom of large water tanks, resulting in some areas retaining excessive sludge, leading to poor wastewater treatment and increased workload for subsequent wastewater treatment. Furthermore, conventional airlift collection devices often introduce sludge along with a significant amount of water, resulting in high sludge moisture content. This necessitates more time and resources for subsequent dewatering, reducing sludge treatment efficiency and causing resource waste.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic sludge airlift collection device, comprising a water tank, wherein first sliding grooves are provided through the upper ends of both the front and rear sides of the water tank, and sliding plates are slidably connected inside the two sets of first sliding grooves; a first push rod is fixedly installed on the upper right side of the water tank, and the output end of the first push rod passes through the right side plate of the water tank and is fixedly connected to the right side of the sliding plate; a second sliding groove is provided through the upper side of the sliding plate, and an I-shaped slider is slidably connected inside the second sliding groove; connecting plates are fixedly connected to both the front and rear ends of the sliding plate through the interior of the first sliding grooves; and a [missing information - likely a device or component] is fixedly installed on the front side of the connecting plate. The second push rod has its output end passing through the front side of the connecting plate and the front side of the slide plate and being fixedly connected to the front side of the I-shaped slider. An air lifting pipe is rotatably connected to the upper center of the I-shaped slider. A telescopic pipe is fixedly connected to the upper left side of the air lifting pipe. A collection tank is fixedly connected to the lower left side of the water tank. Collection pipes are fixedly connected to the left ends of the front and rear sides inside the collection tank. A connecting pipe is rotatably connected to the upper side of the collection pipe. A partition plate is fixedly connected to the middle of the lower side inside the collection tank. A filter inclined plate is fixedly connected to the upper left side of the partition plate. The inside of the collection tank and the right side of the partition plate form a sludge collection trough.

[0006] Preferably, a sealing head is fixedly connected to the upper side of the air lifting pipe.

[0007] Preferably, the lower end of the air lifting pipe passes through the upper side of the I-shaped slider and is fixedly connected to a mud suction funnel.

First chutes 2 are provided through the upper ends of both the front and rear sides of the water tank 1. Slide plates 3 are slidably connected inside the two sets of first chutes 2. A first push rod 4 is fixedly installed on the upper right side of the water tank 1. The output end of the first push rod 4 passes through the right side plate of the water tank 1 and is fixedly connected to the right side of the slide plate 3, effectively changing the lateral position of the slide plate 3. A second chutes 5 are provided through the upper side of the slide plate 3. An I-shaped slider 6 is slidably connected inside the second chutes 5. Connecting plates 7 are fixedly connected through the front and rear ends of the slide plate 3, passing through the interior of the first chutes 2. A second push rod 8 is fixedly installed on the front side of the front connecting plate 7. The output end of the second push rod 8 passes through the front side of the connecting plate 7 and the front side of the slide plate 3 and is fixedly connected to the front side of the I-shaped slider 6, effectively changing the vertical position of the I-shaped slider 6, allowing the sludge suction nozzle 11 to move to any position inside the water tank 1.

[0020] An air-lift pipe 9 is rotatably connected to the upper center of the I-shaped slider 6. A sealing head 10 is fixedly connected to the upper side of the air-lift pipe 9. The lower end of the air-lift pipe 9 passes through the upper side of the I-shaped slider 6 and is fixedly connected to a sludge suction nozzle 11. An air inlet pipe 12 is fixedly connected to the lower rear end of the air-lift pipe 9. A telescopic pipe 13 is fixedly connected to the upper left side of the air-lift pipe 9. A collection tank 14 is fixedly connected to the lower left side of the water tank 1. Collection pipes 15 are fixedly connected to the left ends of the front and rear sides inside the collection tank 14. A connecting pipe 16 is rotatably connected to the upper side of the collection pipe 15. The left side of the 13 passes through the right side of the connecting pipe 16 and communicates with the inside of the connecting pipe 16. Several drain nozzles 17 are fixedly connected to the lower side of the collecting pipe 15. A partition plate 18 is fixedly connected to the middle of the lower side of the inside of the collecting tank 14. A filter inclined plate 19 is fixedly connected to the upper left side of the partition plate 18 to effectively filter the water in the sludge.

A drain pipe 21 is fixedly connected to the lower left side of the collecting tank 14 to effectively discharge the filtered water.

[0021] Working principle: The first push rod 4 can effectively change the lateral position of the slide plate 3 and the suction nozzle 11, and the second push rod 8 can effectively change the vertical position of the I-shaped slider 6 and the suction nozzle 11. By issuing corresponding commands to the first push rod 4 and the second push rod 8, the operator can effectively move the suction nozzle 11 to any position inside the water tank 1. During the movement, the air inlet pipe 12 delivers gas to the bottom of the air lift pipe 9 and forms bubbles. Under the action of the airflow, the sludge at the bottom of the water tank 1 is carried by the bubbles and moved to the air lift pipe. Above pipe 9, it enters the interior of connecting pipe 16 through telescopic pipe 13. Telescopic pipe 13 can extend and retract and has a certain rigidity to ensure that it can remain horizontal when air lifting pipe 9 moves. After sludge and water enter the connecting pipe 16, gas is discharged from the top of the connecting pipe 16. Sludge and water are discharged from each drain nozzle 17 through collection pipe 15 and fall above filter inclined plate 19. Under the action of gravity, sludge will fall into the sludge collection tank 20 along the surface of filter inclined plate 19. Water passes through filter inclined plate 19 and is discharged through drain pipe 21.
