Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an intelligent anti-winding sleeve valve. Background Technology

[0002] Sedimentation tanks are an important component of activated sludge systems, typically installed before / after aeration tanks and before advanced treatment or discharge. They are used to separate sludge from water and to concentrate the sludge in the mixed liquor. Currently, sleeve valves are commonly used to control the discharge of sludge from the tank; this equipment is a critical component of the sedimentation tank. Improperly installed sleeve valves can lead to ineffective sludge-water separation and even result in substandard effluent quality.

[0003] like Figure 6 As shown, the existing sleeve valves all use a flat-mouth design for their mud outlets and lack a flushing device. The maximum lifting height only considers water discharge and is located more than 1 meter below the operating platform. Therefore, the following problems exist:

[0004] ① During sludge discharge, the fibrous waste in the sludge comes into contact with the water outlet surface of the cylinder, generating great frictional resistance. This can easily cause the waste to get tangled around the edge of the outlet, resulting in blockage of the sleeve valve, poor sludge discharge, and a large accumulation of sludge in the pool. This leads to the sludge decomposing and dissolving in the water, seriously affecting the quality of the effluent.

[0005] ② To ensure the normal operation of the treatment system, plant personnel need to frequently inspect and clean the sludge outlet. During operation, personnel need to hold a flashlight in one hand and a long-handled clamp in the other, and then insert their body into the pool to work remotely with the help of tools. This is not only difficult to operate, but also increases the danger of daily operation and creates a great safety hazard. Summary of the Invention

[0006] To address the problems of existing technologies, the present invention aims to design an intelligent anti-winding sleeve valve, which, while achieving the function of separating mud and water in the sedimentation tank, can also reduce and disperse the entanglement of fibrous waste at the mud outlet, ensuring unobstructed sludge discharge and facilitating cleaning.

[0007] To achieve the above objectives, this invention provides an intelligent anti-winding sleeve valve, comprising a fixed sleeve, an inner sleeve, a sealing box, a closing device, and a screw. The fixed sleeve is a hollow tube structure with a sludge inlet at the bottom connected to a sedimentation tank. The inner sleeve has a sludge outlet at the top. The closing device and screw drive the inner sleeve to lift. The valve also includes an anti-winding ring, a winding object identification device, and an air-jetting device. The bottom of the anti-winding ring is connected to the sludge outlet, and the top is folded outward to form an Archimedean spiral surface. The winding object identification device includes a network camera. The system includes a head, server, and operator station computer. The network camera is installed above the sludge outlet and captures high-definition images of the outlet at a set frequency. The server digitizes the uploaded images and transmits them to the operator station computer. A visual recognition model determines the degree of debris entanglement at the outlet and activates an air jetting device to disperse the debris. An elevated foundation is installed above the outlet, and the opening and closing device and screw are installed on the foundation. The screw is extended to match the height of the foundation, allowing the outlet to be raised above the top of the pool.

[0008] Furthermore, the Archimedean spiral surface of the anti-entanglement annulus includes a first surface and a second surface that are folded outwards. The first surface is a quarter circle with a radius that matches the diameter of the annulus, and the second surface is a half circle with a radius that is 0.618 times the radius of the first surface.

[0009] Furthermore, the visual recognition model performs the following steps: first, image enhancement processing is performed; then, the physical boundaries of the fibrous waste are accurately separated; and finally, the degree of entanglement at the mud outlet is determined by extracting feature values.

[0010] Furthermore, the degree of entanglement includes three levels: normal, obvious, and severe. The normal level indicates that there is no obvious entanglement of waste at the sludge outlet, and observation should continue. The obvious level indicates that fibrous waste has just begun to entangle, and the impact is relatively small. The air jet device can be automatically activated to blow away the entangled waste at the sludge outlet. The severe level indicates that the entanglement of waste is very serious and has affected the normal sludge discharge of the sleeve valve, requiring manual cleaning. When the degree of entanglement reaches the obvious or severe level, the computer at the operation station will issue an alarm.

[0011] Furthermore, the operating computer includes a database for storing image materials and historical operation information. The visual recognition model performs self-learning and algorithm iteration based on the database to improve the accuracy of entanglement recognition.

[0012] Furthermore, the air-flushing device includes an air compressor, a main compressed air pipe, and several branch compressed air pipes. One end of the main compressed air pipe is connected to the air compressor, and the other end is connected to the branch compressed air pipes. The branch compressed air pipes are installed on the bottom inner wall of the sleeve valve, with their openings facing the mud outlet.

[0013] Furthermore, the compressed air branch pipes are evenly distributed around the bottom inner wall of the sleeve valve, and openings are provided at corresponding positions on the inner wall.

[0014] Furthermore, the air volume and air pressure of the air compressor can be automatically or manually adjusted according to the degree of winding, and the ventilation frequency and interval can be adjusted.

[0015] Furthermore, the elevated foundation is installed above the mud outlet, the opening and closing device and the screw are installed on the elevated foundation, and the extended height of the screw matches the height of the elevated foundation.

[0016] Furthermore, the raised foundation is made of corrosion-resistant metal and has a square frame structure with cleaning holes on all four sides.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. This invention is based on the design of an Archimedes spiral to prevent tangling of circular rings, which reduces the resistance of sludge discharge at the outlet and significantly reduces the probability of fibrous waste tangling by utilizing the smooth curved surface of the spiral, thus effectively alleviating the problem of waste tangling.

[0019] 2. This invention uses image recognition and machine learning to automatically determine the degree of mud entanglement at the mud outlet, and simultaneously pushes alarm information and activates the solution.

[0020] 3. This invention relies on the interaction between gas and liquid phases to generate shear force and disturbance force, which quickly disperses tangled fibrous objects, assisting in the sludge removal and cleaning process and ensuring smooth sludge removal.

[0021] 4. This invention raises the sludge outlet to above the top of the pool by raising the foundation, which facilitates the removal of garbage and greatly reduces the difficulty and risk of the removal work.

[0022] 5. The modules of this invention can be installed individually or all modules can be included. In practical applications, the appropriate modules can be selected based on the content of the entangled material in the influent.

[0023] 6. This invention can greatly reduce the number of cleaning operations, reduce the labor intensity of workers, and ensure personal safety.

[0024] 7. The present invention has a reasonable overall structure and strong practicality, and can be widely used in the sludge discharge process of sleeve valve in the field of sewage treatment. Attached Figure Description

They are merely relational terms determined for the convenience of describing the structural relationship of the various components or elements of this invention, and do not specifically refer to any component or element in this invention, and should not be construed as limiting this invention.

[0038] In this invention, terms such as "fixed connection," "connected," and "linked" should be interpreted broadly, indicating a fixed connection, an integral connection, or a detachable connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can determine the specific meaning of these terms in this invention based on the specific circumstances, and they should not be construed as limitations on the invention.

[0039] This invention discloses an intelligent anti-winding sleeve valve, the innovation of which lies in setting an anti-winding ring of Archimedes spiral, image recognition function of entangled objects, and matching air flushing and garbage lifting device to assist the sludge discharge process and ensure smooth sludge discharge.

[0040] Figure 1 The diagram shown is a schematic representation of the overall structure of the sleeve valve of the present invention. Figure 1 As shown, the intelligent anti-winding sleeve valve of the present invention includes a fixed sleeve 105, an inner sleeve 103, a sealing box 104, an opening and closing device 101, and a screw 102. The fixed sleeve 105 is a hollow tube structure with a sludge inlet at the bottom connected to the sedimentation tank. The inner sleeve 103 has a sludge outlet at the top. The opening and closing device 101 and the screw 102 control the raising and lowering of the anti-winding ring 201 and the inner sleeve 103: when the top of the anti-winding ring 201 is lower than the liquid surface, sludge discharge begins; when the top of the anti-winding ring 201 is higher than the liquid surface, sludge discharge stops, thereby realizing the sludge discharge function.

[0041] The anti-tangling ring 201, designed based on the Archimedes spiral, can greatly reduce the resistance during the sludge discharge process and reduce the amount of waste tangling at the sludge outlet. The network camera 301, server 302, and operator station computer 303 collect images of the sludge outlet in real time and automatically determine the degree of waste tangling at the sludge outlet. When a small amount of waste is tangled at the sludge outlet, the air-puffing modules 501, 502, and 503 can intermittently inflate the air to blow away the waste along the outlet. When there is too much tangled waste, the anti-tangling ring 201 and inner sleeve 103 can be lifted above the ground by the waste lifting device, avoiding the risk of personnel entering the pool for operation.

[0042] like Figure 2As shown, the anti-winding annular body 201 adopts a three-dimensional annular structure with a diameter adapted to the size of the sludge outlet. It is made of corrosion-resistant metal and has a smooth surface. The Archimedean spiral surface of the anti-winding annular body includes an outwardly folded first surface and a second surface. The first surface is a quarter circle with a radius adapted to the diameter of the annular body, ranging from 50 to 150 mm; the second surface is a half circle with a radius 0.618 times that of the first surface, ensuring a reasonable overall structure. During sludge discharge, the planar design of the existing sleeve valve outlet causes significant frictional resistance, easily leading to debris entanglement on the edge. This invention, based on the Archimedean spiral and the golden ratio, replaces the planar outlet with an annular anti-winding annular body. The contact surface with the sludge becomes a smooth curved surface, which can greatly reduce frictional resistance, prevent debris entanglement and sleeve blockage, and ensure continuous and smooth sludge discharge.

[0043] A network camera 301 is installed above the sludge outlet, collecting and uploading high-definition images of the outlet at a set frequency. The server 302 digitizes the uploaded images and uploads them to the operator station computer 303, which uses a visual recognition model to automatically determine the degree of debris entanglement at the outlet. The database continuously accumulates image information and algorithms to enhance image recognition accuracy. The visual recognition model performs the following steps: first, image enhancement processing; then, precise separation of the physical boundaries of the fibrous debris; and finally, determination of the degree of entanglement at the outlet by extracting feature values. The entanglement degree determined by the model includes three levels: normal, obvious, and severe. The normal level indicates that there is currently no obvious debris entanglement at the outlet, and observation continues. The obvious level indicates that fibrous debris has just begun to entangle, with a small impact, and the air jet device can be automatically activated to disperse the debris entanglement at the outlet. The severe level indicates that the debris entanglement is very serious, affecting the normal sludge discharge from the sleeve valve, and manual cleaning is necessary. When the entanglement degree reaches the obvious or severe level, the operator station computer issues an alarm. Traditional sleeve valves cannot automatically detect blockages caused by sludge entanglement, requiring workers to insert themselves into the tank during inspection, posing a safety hazard. This invention uses visual recognition to automatically identify and trigger an alarm for sludge entanglement blockages in sleeve valves.

[0044] like Figure 3As shown, the opening and closing device 101 is installed on the raised foundation 401, increasing the adjustment range of the inner sleeve 103. Together with the screw 102, it lifts the garbage entangled in the sludge outlet to above the top of the pool (elevation H0). The raised foundation 401 is made of corrosion-resistant metal, and four cleaning holes 402 are evenly distributed on its side, along with corrosion-resistant push-pull plates. Previously, when cleaning the garbage from the sludge outlet, workers were limited by the pool structure and equipment type, requiring them to lower themselves into the pool, making the operation extremely inconvenient and dangerous. This invention allows workers to complete the cleaning work from the ground. During cleaning, workers first use the opening and closing device 101 and screw 102 to lift the inner sleeve 103 to above the top of the pool (H0). Then, depending on the entanglement situation, they open the corrosion-resistant push-pull plates of the corresponding cleaning holes 402, using tools or their hands to peel the entangled garbage off the anti-entanglement ring 201 (i.e., the sludge outlet), and finally remove it from the pool. After cleaning is completed, lower the inner sleeve 103 and the anti-winding ring 201 to the corresponding elevation, and close the corrosion-resistant push-pull plate to complete the operation.

[0045] Preferably, the raised foundation 401 adopts a square design with a side length between 1000mm and 3000mm. The height must meet the requirements for garbage lifting, between 1.0 and 2.0m; the four cleaning holes adopt a rectangular design, with the top of the holes flush with the top plate of the foundation, the length between 800mm and 1500mm, the height not less than 1000mm, and are equipped with corrosion-resistant push-pull plates.

[0046] like Figure 4 , 6 As shown, the air-cushioning device includes an air compressor 501, a main compressed air pipe 502, and compressed air branch pipes 503. The air compressor 501 operates intermittently depending on the equipment blockage, with an intermittent frequency selectable from 5 to 30 minutes / hour, sufficient to meet the air-cushioning requirements. One end of the main air pipe 502 is connected to the air compressor 501, and the other end is connected to several air branch pipes 502.

[0047] Preferably, several compressed air branch pipes 502 are evenly distributed and fixed circumferentially on the inner wall of the bottom of the sleeve valve, with the pipe openings facing upwards. Corresponding openings 504 are located on the cylinder body to ensure a reasonable and unobstructed airflow path. Compressed air pipes 502 and 503 are both made of corrosion-resistant metal, with diameters of DN25 and DN50 respectively. Existing sleeve valves rely solely on water pressure for sludge discharge. When debris becomes entangled at the outlet, the sludge discharge resistance is high, easily leading to blockages. This invention utilizes the interaction of gas and liquid phases to generate shear and disturbance forces, rapidly dispersing the clumps of debris while simultaneously providing upward airflow. Intermittent compressed air flushes debris hanging on the edges down, assisting in the sludge discharge and cleaning process and reducing the labor intensity of workers.

[0048] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and additions without departing from the method of the present invention, and these improvements and additions should also be considered within the scope of protection of the present invention.
