Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to an intelligent sewage shallow-layer flotation treatment device. Background Art

[0002] The shallow flotation device is a high-efficiency water purification equipment that uses small bubbles or tiny bubbles to make impurities in the medium float to the surface. It is mainly composed of a pool body, a dissolved air system, a water distribution component and a scum removal component.

[0003] The most direct problem of the existing shallow flotation device is that when the scum removal component removes scum, the scum adheres to the scum removal bucket. After a long time, the resistance increases, affecting the discharge effect of the scum. The current conventional methods are mainly: using water flushing: For example, the existing patent CN118108290B discloses a shallow flotation machine for industrial wastewater treatment and a treatment method thereof, in which a flushing component is provided to prevent the scum from adhering to the inner wall of the scraper bucket to ensure the stable discharge of the scum. However, in actual use, it is not considered that the water falling after flushing may break the originally stable water flow state and microbubble distribution in the flotation tank. During the flotation process, the microbubbles need to be evenly distributed and combined with the suspension. The falling of flushing water may cause the microbubbles to aggregate or disperse unevenly. The concentration of microbubbles in some areas may be too high or too low, which will affect the attachment and floating speed of suspended matter and reduce the flotation efficiency. The falling of flushing water may have an impact on the scum layer, making the scum layer unstable. Some scum may be re-mixed into the water, increasing the difficulty of flotation separation. It may also lead to incomplete scraping and affect the overall treatment effect of the flotation tank. Another way is to shut down the machine regularly for manual cleaning, which is troublesome and greatly reduces the sewage treatment efficiency. For this reason, we propose an intelligent shallow flotation treatment device for sewage. Summary of the invention

[0005] Two scum collecting assemblies, the two scum collecting assemblies are arranged on both sides of the water distribution assembly, and the scum collecting assemblies include a scum discharge pipe and a scum removal bucket connected to each other, and the scum is collected by rotating the scum discharge pipe and the scum removal bucket;

[0006] A synchronous drive assembly, which is used to drive the two slag discharge pipes to rotate in opposite directions to synchronously collect slag and reduce unilateral water flow interference;

[0007] The gravity slag removal component is arranged on the slag removal bucket, and the gravity slag removal component includes a magnetic suction tube and a guide connection piece. The magnetic suction tube is hollow inside, and the magnetic suction tube can be adsorbed on the inner end of the slag removal bucket by magnetic attraction. The magnetic suction tube can move along the inner wall of the slag removal bucket under the action of gravity through the guide connection piece to scrape off the adhered slag.

[0008] In some embodiments, the outer wall of the magnetic suction tube is provided with a plurality of water inlet holes connected to the interior in a circular array along the length direction, a scraping edge is provided at the end of the water inlet hole, and a filter screen is provided inside the water inlet hole to prevent scum from entering.

[0009] In some embodiments, a plurality of magnetic blocks are embedded in the inner wall of the slag removal bucket near the end along the length direction, and the magnetic attraction force of the magnetic blocks on the magnetic suction tube is smaller than the gravity of the magnetic suction tube.

[0010] In some embodiments, the guide connection member includes a guide groove opened on the side wall of the slag removal bucket, a guide block is slidably connected in the guide groove, a connecting rod is connected between the outer wall of the guide block and the end of the magnetic suction tube, and the magnetic suction tube is rotatably connected to the connecting rod.

[0011] In some embodiments, the synchronous drive assembly includes a first drive part and a second drive part, the first drive part is used to drive one slag discharge pipe to rotate, and the second drive part operates synchronously with the first drive part and is used to drive another slag discharge pipe to rotate in the opposite direction.

[0012] In some embodiments, the first driving part includes a motor installed on a water distribution frame, and the motor and an end of one of the slag discharge pipes are both installed with a first pulley, and the two first pulleys are connected by a belt.

[0013] In some embodiments, the second driving part includes a second pulley and a third pulley rotatably mounted on the walking frame, the second pulley and the end of the slag discharge pipe are also connected by a belt, a gear is installed at the end of the second pulley and the third pulley, and the two gears are meshed, and a fourth pulley is installed at the other end of the slag discharge pipe, and the third pulley and the fourth pulley are connected by a belt transmission.

[0014] In some embodiments, a slag dropping channel is provided at the inner end of the connection between the slag removal bucket and the slag discharge pipe, a guide pipe is provided at the slag discharge end of the slag discharge pipe, and the slag discharge pipe is rotatably connected to the guide pipe.

[0015] In some embodiments, an inner wall of the slag removal bucket is provided with an arc-shaped shallow groove near the end and along the length direction, and the magnetic block is located in the arc-shaped shallow groove. When the magnetic suction tube is in the arc-shaped shallow groove, the magnetic suction tube protrudes outward from the inner wall of the slag removal bucket.

[0016] In some embodiments, a plurality of rolling balls are disposed at the inner bottom of the guide groove along the guide direction, and an end of the guide block contacts the balls.

[0017] The present invention has at least the following beneficial effects:

[0018] 1. Improve the scum collection efficiency: Two scum collection components with opposite rotation can collect scum from both sides of the water distributor component at the same time. Compared with a single collection structure, it can cover a larger pool surface area and collect the scum generated during the flotation process in time to prevent excessive accumulation of scum on the water surface, which affects the flotation effect and water quality. The opposite rotation directions enable the collection structures to cooperate with each other during movement to encircle the scum around the water distributor component, reduce the situation where scum accumulates in certain areas and cannot be collected in time, and keep the surface of the flotation pool clean.

[0019] 2. Reduce water flow interference: The two scum collection components rotate in opposite directions, and the water flows generated by their movement offset each other partially. Compared with the water flow disturbance caused by the unidirectional rotation of a single collection structure, the overall interference to the water flow in the flotation tank is smaller, which is conducive to the stable combination and floating of flocculants and bubbles in the water, improving the effect of flotation separation and making the solid-liquid separation more thorough.

[0020] 3. Optimize water flow pattern: The two scum collection components rotating in opposite directions can form a specific water flow pattern on both sides of the water distribution mechanism, which helps to guide the scum in the water flow to move toward the collection structure, while allowing the clean water to flow downward better, achieving effective separation of scum and clean water, and improving the water purification effect. The opposite forces can form a special water flow traction mode, so that the scum on the water surface is quickly gathered to the area between the two scum collection structures. Compared with the force in a single direction, this method can more effectively concentrate the scum scattered on both sides of the water distribution mechanism, which is convenient for subsequent collection and cleaning, and improves the efficiency and integrity of scum collection.

[0021] 4. Balanced mechanical stress: When the two slag collection components with opposite rotations are in operation, the torque and force generated are balanced with each other, which can reduce the mechanical stress of the water distribution mechanism and the entire flotation equipment, reduce the wear and deformation of the equipment caused by uneven force, extend the service life of the equipment, and ensure the stability of equipment operation.

[0022] 5. Simplified structure: The synchronous drive assembly can realize the synchronous drive of the two slag discharge pipes, making them rotate in opposite directions. This design not only effectively reduces the number of driving components and significantly improves the degree of synchronization, but also greatly saves maintenance workload and reduces manufacturing costs.

[0023] 6. Automatic slag removal, high efficiency and time saving: The traveling frame rotates around a fixed center of the circle, and the synchronous drive assembly synchronously drives the slag discharge pipe and the slag removal bucket to rotate in the opposite direction. The magnetic suction tube automatically completes the collection and scraping of floating slag based on the interaction of gravity, magnetism and friction, without excessive manual intervention, saving labor costs. This automatic cycle working mode can quickly scrape the floating slag on the slag removal bucket in each cycle, which improves the slag removal efficiency, saves the time for sewage treatment, and improves the working efficiency of the entire flotation equipment.

[0024] 7. Gravity further removes slag: When the slag bucket collects slag, a small amount of water enters the magnetic suction tube, flows out during the movement of the magnetic suction tube, and flushes the inner wall of the slag bucket, further enhancing the effect of removing adhered slag, helping to keep the inner wall of the slag bucket clean, maintain the equipment in good working condition, and reduce the workload of manual cleaning.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figure 1-Figure 11As shown, the present invention provides a technical solution: an intelligent sewage shallow flotation treatment device, comprising a shallow flotation machine body 1, a traveling frame 2 is installed on the shallow flotation machine body 1, a water distribution component 3 is arranged on the traveling frame 2, the traveling frame 2 rotates with the center of the shallow flotation machine body 1 as the center of a circle to achieve continuous water distribution, air dissolution and slag removal, the water inlet end of the water distribution component 3 is connected to the raw water inlet pipe through a rotating connector, the bottom end of the raw water inlet pipe passes through the bottom end of the shallow flotation machine body 1, an electromagnetic valve is installed on the raw water inlet pipe, a turbidity sensor and a PH sensor are also installed in the shallow flotation machine body 1 for real-time monitoring of water quality, and also includes Controller (PLC) to achieve automatic operation and monitoring. In addition, the intelligent sewage shallow flotation treatment device also includes a scum collecting component 4 and a synchronous driving component 5. The scum collecting component 4 is provided with two, and the two scum collecting components 4 are relatively arranged on both sides of the water distribution component 3 to synchronously collect scum from both sides. The scum collecting component 4 includes a connected scum discharge pipe 41 and a scum removal bucket 42. The scum is collected by rotating the scum discharge pipe 41 and the scum removal bucket 42. The synchronous driving component 5 is used to drive the two scum discharge pipes 41 to rotate in opposite directions to synchronously collect scum and to reduce unilateral water flow interference. The two scum collecting components that rotate in opposite directions 4 can collect scum from both sides of the water distribution component 3 at the same time, which can cover a larger pool surface area than a single collection structure, and can collect scum generated during the flotation process in time, preventing scum from accumulating too much on the water surface and affecting the flotation effect and water quality. Secondly, the opposite rotation directions enable the collection structures to cooperate with each other during movement, forming a siege for the scum around the water distribution component 3, reducing the situation where scum gathers in certain areas and cannot be collected in time, and keeping the surface of the flotation pool clean. In addition, the two opposite forces restrain each other, forming a relatively stable water flow boundary on the surface of the flotation pool, reducing the scum from the side or the side of the collection structure due to water flow fluctuations. The possibility of escaping around ensures that more scum can be successfully collected, thereby improving the effect of scum removal. A scum dropping channel 411 is provided at the inner end of the connection between the scum bucket 42 and the scum discharge pipe 41, and a guide pipe 43 is provided at the scum discharge end of the scum discharge pipe 41, and the scum discharge pipe 41 is rotatably connected to the guide pipe 43. The scum bucket 42 collects the scum as the scum discharge pipe 41 rotates, and as it rotates upward, under the action of gravity, the scum enters the scum discharge pipe 41 through the scum dropping channel 411, wherein the end of the scum discharge pipe 41 close to the guide pipe 43 is lower, and the scum in the scum discharge pipe 41 can move along the scum discharge pipe 41 to the guide pipe 43 and then enter the scum collection area and be discharged.

[0042] Among them, see Figure 4-Figure 6 As shown, the synchronous drive assembly 5 includes a first drive part 51 and a second drive part 52. The first drive part 51 is used to drive one slag discharge pipe 41 to rotate, and the second drive part 52 operates synchronously with the first drive part 51 and is used to drive the other slag discharge pipe 41 to rotate in the opposite direction.

[0043] See also Figure 5 As shown, the first driving part 51 includes a motor 511 installed on the water distribution frame, and the motor 511 is preferably a servo motor. The motor 511 and the end of one of the slag discharge pipes 41 are both installed with a first pulley 512, and the two first pulleys 512 are connected by a belt. The motor 511 is started, and the first pulley 512 at the output end of the motor 511 is rotated, and then the first pulley 512 is used to drive the slag discharge pipe 41 connected to the first pulley 512 to rotate to collect the slag.

[0044] See also Figure 4-Figure 5 As shown, the second driving part 52 includes a second pulley 521 and a third pulley 523 rotatably mounted on the walking frame 2, and the second pulley 521 and the end of the slag discharge pipe 41 are also connected by a belt. A gear 522 is installed at the end of the second pulley 521 and the third pulley 523, and the two gears 522 are meshed with each other. A fourth pulley 524 is installed at the end of the other slag discharge pipe 41, and the third pulley 523 and the fourth pulley 524 are connected by belt transmission. Under the drive of the motor 511, its output shaft drives the first pulley 512 to rotate, and the power is transmitted to the second pulley 521 through the belt transmission mechanism. The second pulley 521 meshes with another gear 522 through the gear 522 coaxially mounted therewith, so as to realize power steering, thereby driving the third pulley 523 to rotate in the opposite direction, so as to realize the opposite rotation of the other slag discharge pipe 41 to collect slag.

[0045] See also Figure 1-Figure 2 As shown, the intelligent sewage shallow flotation treatment device also includes a gravity slag removal component 6, which is arranged on the slag removal bucket 42, and the gravity slag removal component 6 includes a magnetic suction tube 61 and a guide connection 62, the interior of the magnetic suction tube 61 is hollow, and the magnetic suction tube 61 can be adsorbed at the inner end of the slag removal bucket 42 by magnetic attraction, and the magnetic suction tube 61 can move against the inner wall of the slag removal bucket 42 under the action of gravity through the guide connection 62 to scrape off the slag adhered to the inner wall of the slag removal bucket 42.

[0046] See also Figure 8-Figure 9 As shown, a plurality of magnetic blocks 63 are embedded along the length direction near the end of the inner wall of the slag bucket 42, and the magnetic attraction force of the magnetic blocks 63 on the magnetic suction tube 61 is less than the gravity of the magnetic suction tube 61. An arc-shaped shallow groove is opened on the inner wall of the slag bucket 42 near the end and along the length direction, and the magnetic blocks 63 are in the arc-shaped shallow groove. The magnetic blocks 63 are arc-shaped structures adapted to the magnetic suction tube 61. When the magnetic suction tube 61 is in the arc-shaped shallow groove, the magnetic suction tube 61 protrudes out of the inner wall of the slag bucket 42, so as to play a certain blocking role after the slag is initially scooped onto the slag bucket 42, thereby reducing the occurrence of the slag sliding out along the end of the slag bucket 42.

[0047] See also Fig.11As shown, the outer wall of the magnetic suction tube 61 is provided with a plurality of water inlet holes 611 connected to the interior in a circular array along the length direction, a scraping edge 612 is provided at the end of the water inlet hole 611, and a filter screen 613 is provided inside the water inlet hole 611 to block the entry of scum. When the scum is scooped up by the scum bucket 42, the upper water can enter the magnetic suction tube 61 through the scum bucket 42, and when the magnetic suction tube 61 subsequently moves along the inner wall of the scum bucket 42 under the action of gravity, the water inside the magnetic suction tube 61 can also flow out under the action of gravity to flush the inner wall of the scum bucket 42.

[0048] See also Figure 7-Figure 11 As shown, the guide connection member 62 includes a guide groove 623 opened on the side wall of the slag removal bucket 42, a guide block 621 is slidably connected in the guide groove 623, a connecting rod 622 is connected between the outer wall of the guide block 621 and the end of the magnetic suction tube 61, and the magnetic suction tube 61 is rotatably connected to the connecting rod 622.

[0049] Through the above, in specific use, the sewage to be treated is introduced into the flotation equipment. As the walking frame 2 rotates around the fixed center of the circle, the synchronous drive component 5 takes effect, and synchronously drives the two slag discharge pipes 41 and the slag removal bucket 42 to rotate in the opposite direction, so as to collect the floating slag. When the slag removal bucket 42 is at the bottom position, the magnetic suction tube 61 is adsorbed on the inner wall of the slag removal bucket 42 near the end by the magnetic block 63. As the magnetic suction tube 61 rotates upward, once the downward gravity of the magnetic suction tube 61 itself is greater than the sum of the suction force of the magnetic block 63 and the friction force (that is, the resistance The magnetic suction tube 61 will be separated from the magnetic block 63. In the process of continuing to rotate upward, the magnetic suction tube 61 moves along the guide groove 623 by relying on the guide block 621, so that it always sticks to the inner wall of the slag bucket 42. In this process, the scraper edge 612 will scrape the scum adhering to the inner wall of the slag bucket 42 to the slag channel 411. When the slag bucket 42 originally at the lower end rotates through the highest point, under the action of gravity, the magnetic suction tube 61 that has moved close to the slag channel 411 will move in the opposite direction against the inner wall of the slag bucket 42. Before the slag bucket 42 rotates to collect scum next time, the magnetic suction tube 61 can be re-adsorbed on the magnetic block 63. Through this continuous cycle of working mode, the scraping of scum on the slag bucket 42 can be automatically completed in each cycle, which is convenient and saves time.

[0050] In addition, each time the slag removal bucket 42 picks up slag, a small amount of water will enter the magnetic suction tube 61. When the magnetic suction tube 61 subsequently moves along the inner wall of the slag removal bucket 42, the water inside the magnetic suction tube 61 flows out under the action of gravity, thereby flushing the inner wall of the slag removal bucket 42, further enhancing the effect of removing adhered slag.

[0051] Embodiment 2: This embodiment is an extension of Embodiment 1: a plurality of rolling balls are provided at the inner bottom of the guide groove 623 along the guiding direction, and the end of the guide block 621 contacts the balls. These balls are evenly spaced, and their presence greatly optimizes the smoothness of the guiding. The balls are made of a special high-strength, wear-resistant material, can withstand greater pressure and have a long service life. The end of the guide block 621 contacts the balls precisely. When the guide block 621 performs a guiding movement in the guide groove 623, rolling friction is formed between the end and the balls. Compared with traditional sliding friction, the friction force is greatly reduced, making the guiding process easier and more efficient, while also reducing the wear between components, effectively improving the stability and reliability of the entire guiding system.
