Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to an integrated air flotation sedimentation machine for wastewater treatment. Background Technology

[0002] An integrated air flotation and sedimentation system is a device that effectively combines air flotation and sedimentation, two wastewater treatment processes. By injecting microbubbles into the wastewater, suspended solids that are difficult to settle naturally (such as grease, colloidal substances, and fine solid particles) adhere to the bubbles and float to the surface. The scum is then removed by a scraper. These microbubbles are typically generated using a dissolved air release system. First, air is dissolved in water under high pressure to form dissolved air water. When this dissolved air water enters the atmospheric pressure air flotation zone, excess air is released as microbubbles.

[0003] Existing wastewater treatment equipment removes internal impurities through air flotation and sedimentation. However, the impurities generated during air flotation float on the surface of the wastewater. Current devices require scrapers to remove these floating objects, which is inefficient. Furthermore, due to limitations in the scraper's structure and trajectory, it is difficult to completely remove all floating matter from the surface of the air flotation tank. Therefore, we propose an integrated air flotation and sedimentation machine for wastewater treatment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an integrated air flotation sedimentation machine for sewage treatment, so as to solve the technical problems of the current air flotation scraper having a limited running trajectory, making it difficult to scrape off the floating matter and resulting in low cleaning quality.

[0005] To solve the above technical problems, this utility model provides the following technical solution: an integrated air flotation sedimentation machine for sewage treatment, comprising an internal frame, a central plate, and blades. The internal frame is installed inside an assembly frame, and the assembly frame is installed at the upper opening of the housing. Assembly openings are provided on both inclined surfaces of the internal frame. Adjustment plates are slidably installed on both ends of the internal frame. A central plate is fixed in the middle of the internal frame, and a material storage box is provided on the upper surface of the central plate. Bottom cylinders are fixed at both ends of the lower surface of the central plate, and a lifting cylinder is slidably installed on the lower end of the bottom cylinder. An internal pipe is installed through the lifting cylinder, and the lower end of the internal pipe is fixed on the blades.

[0006] In use, this invention is powered by an external power source. The flotation pipe is inserted into the wastewater tank through the assembly port. Dissolved air water is injected into the wastewater through the pipe, forming tiny floating bubbles. These bubbles adhere to suspended matter, forming floating impurities. Based on the liquid level, the motor on the central plate is activated, driving the screw to rotate. The screw thread drives the adjusting plate, which, in conjunction with the limit rod, achieves relative displacement between the two adjusting plates. When the two adjusting plates approach each other, the lower linkage arm drives the lifting cylinder to descend within the bottom cylinder. Floating impurities are then sucked up through the material inlet at the lower end of the internal pipe and discharged into the storage box through the discharge pipe. This structural design allows the impurity removal mechanism of this device to be easily adjusted according to the wastewater level, effectively removing impurities from the wastewater surface. It is highly adaptable, with lotus leaf-shaped blades and a surface layer on the upper part of the blades... A pressure sensor is installed at the connection between the recessed opening, the built-in pipe, and the lifting cylinder. When the blades are in contact with the sewage surface, the pressure sensor detects a signal due to buoyancy. The height is adjusted so that the blades are positioned below the sewage surface. At this point, suspended impurities on the sewage surface correspond to the recessed opening of the blades, and the liquid level is below the inlet. The negative pressure pump is then activated to create negative pressure in the storage box. This negative pressure forces the suspended impurities on the sewage surface through the blades and into the storage box via the inlet, built-in pipe, and discharge pipe. The above structural design allows the blades to generate an upward thrust in conjunction with the buoyancy of the sewage. The pressure sensor at the connection point facilitates accurate detection of the inlet submerged below the sewage surface, making it convenient to remove suspended impurities. Furthermore, this device uses a suction method for impurity removal, eliminating cleaning dead zones and ensuring high-quality cleaning.

[0007] Preferably, adjustment openings are provided at both ends of both sides of the built-in frame, and the outer end of the adjustment plate is slidably installed in the corresponding adjustment opening.

[0008] Preferably, the two ends of the central plate are respectively provided with a screw and a limiting rod, and the two ends of the screw are threaded through the rear ends of the two adjusting plates, and the limiting rods are through the front ends of the adjusting plates.

[0009] Preferably, a negative pressure pump body is installed on one side of the central plate, and the port of the negative pressure pump body is connected to the upper inside of the storage box. A sealing gasket is provided at the connection between the storage box and the box cover with the upper opening.

[0010] Preferably, the blade is designed in the shape of a lotus leaf, and the upper side of the blade is provided with a recess. The lower end of the internal tube is provided with a material inlet, and the material inlet is located inside the recess.

[0011] Preferably, the upper end of the built-in tube is provided with a discharge pipe, and the upper end of the discharge pipe passes through and connects to the upper side of the inside of the storage box, and the lower end of the discharge pipe is connected to the inside of the built-in tube through a flexible hose.

[0012] Preferably, side openings are provided on both sides of the bottom cylinder, and a linkage arm is installed on the lower end face of the adjusting plate via a hinge, and the lower end of the linkage arm passes through the side opening and is rotatably connected to the side of the lifting cylinder via a hinge.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the design of an adjustment plate and external power supply, allows the air flotation pipeline to be inserted into the sewage tank through the assembly port. Dissolved air water is injected into the sewage through the pipeline, forming floating microbubbles. These bubbles adhere to suspended matter, forming floating impurities. Based on the liquid level, the motor on the central plate is activated, driving the screw to rotate. The screw thread drives the adjustment plate in conjunction with the limit rod, achieving relative displacement between the two adjustment plates. When the two adjustment plates approach each other, the lower linkage arm drives the lifting cylinder to descend within the bottom cylinder. The floating impurities are sucked up through the material inlet at the lower end of the built-in pipe and discharged into the storage box through the discharge pipe. Through the above structural design, the impurity removal mechanism of this device can be easily adjusted according to the sewage level, effectively removing impurities from the sewage surface, and has strong adaptability.

[0015] 2. This utility model also features a blade design shaped like a lotus leaf, with a recessed opening on the upper surface. A pressure sensor is located at the connection between the internal tube and the lifting cylinder. When the blade is in contact with the wastewater surface, buoyancy causes the pressure sensor to detect a signal. By adjusting the height, the structure allows the blade to be positioned below the wastewater surface. At this point, suspended impurities on the wastewater surface correspond to the recessed opening of the blade, and the liquid level is below the inlet. The negative pressure pump is then activated to create negative pressure in the storage box. Through this negative pressure, suspended impurities on the wastewater surface are screened by the blade and then guided into the storage box for storage through the inlet, internal tube, and discharge pipe. The above structural design allows the blade to generate an upward thrust in conjunction with the buoyancy of the wastewater. The pressure sensor at the connection facilitates accurate detection of the inlet submerged below the wastewater surface, making it convenient to remove suspended impurities. Furthermore, this device uses a suction method for impurity removal, eliminating cleaning dead zones and ensuring high-quality cleaning. Attached Figure Description

Adjusting ports 302 are provided on both ends of the internal frame 3. The outer ends of the adjusting plates 5 are slidably installed in the corresponding adjusting ports 302. A screw 602 and a limiting rod 603 are respectively provided at both ends of the central plate 6. The two ends of the screw 602 are threaded through the rear ends of the two adjusting plates 5, and the limiting rod 603 is through the front end of the adjusting plate 5. A negative pressure pump body 601 is installed on one side of the central plate 6, and the pipe of the negative pressure pump body 601 is connected to the material storage box 4. Inside the upper part of the device, a sealing gasket is provided at the connection between the storage box 4 and the box cover with the upper opening. It is powered by an external power source. The air flotation pipeline is inserted into the sewage in the tank 1 through the assembly port 301. Dissolved air water is injected into the sewage through the pipeline to form floating microbubbles. The bubbles adhere to the suspended matter to form floating impurities. According to the liquid level, the motor on the central plate 6 is activated to drive the screw 602 to rotate. The screw 602 drives the adjusting plate 5 in conjunction with the limiting rod 603 to realize the relative displacement of the two adjusting plates 5. When the two adjusting plates 5 approach each other, the lifting cylinder 704 is driven to descend in the bottom cylinder 7 through the linkage arm 501 on the lower side. The floating impurities are sucked up through the material inlet 705 at the lower end of the built-in pipe 706 and introduced into the storage box 4 through the discharge pipe 702 for storage. Through the above structural design, the impurity removal mechanism of this device can be easily adjusted according to the height of the sewage liquid level, which can effectively remove impurities on the surface of sewage and has strong adaptability.

[0024] like Figures 2 to 6As shown, this utility model relates to an integrated air flotation sedimentation machine for sewage treatment, comprising an internal frame 3, a central plate 6, and blades 701. Both ends of the lower surface of the central plate 6 are fixed with a bottom cylinder 7, and a lifting cylinder 704 is slidably installed at the lower end of the bottom cylinder 7. An internal tube 706 is installed through the lifting cylinder 704, and the lower end of the internal tube 706 is fixed to the blades 701. The blades 701 are designed in the shape of lotus leaves, and a recess is provided on the upper side of the blades 701. A pick-up point is provided at the lower end of the internal tube 706. The material inlet 705 is located within the recessed opening. A discharge pipe 702 is located at the upper end of the internal tube 706, with its upper end penetrating and connecting to the upper interior of the storage box 4. The lower end of the discharge pipe 702 is connected to the interior of the internal tube 706 via a flexible hose. Side openings 703 are provided on both sides of the bottom cylinder 7. A linkage arm 501 is hinged to the lower end of the adjusting plate 5, and its lower end passes through the side opening 703 and is rotatably connected to the side of the lifting cylinder 704 via a hinge. The blade... The blade 701 is designed in the shape of a lotus leaf, and the upper surface of the blade 701 has a recess. A pressure sensor is installed at the connection between the built-in tube 706 and the lifting cylinder 704. When the blade 701 is in contact with the sewage surface, the pressure sensor detects a signal through buoyancy. By adjusting the height, the structure allows the blade 701 to be placed below the sewage surface. At this time, the suspended impurities on the sewage surface correspond to the recess of the blade 701, and the liquid level is above the feeding port 705. Then, the negative pressure pump body 601 is activated to generate negative pressure in the storage box 4. Through the negative pressure, the suspended impurities on the sewage surface are screened by the blade 701 and then introduced into the storage box 4 for storage through the feeding port 705, the built-in tube 706, and the discharge pipe 702. Through the above structural design, the blade 701, together with the buoyancy of the sewage, generates an upward thrust. The pressure sensor at the connection makes it easy to detect that the feeding part is accurately submerged below the sewage surface, which is convenient for the collection of suspended impurities. In addition, this device uses a suction method for impurity discharge, with no dead corners in cleaning, ensuring the quality of cleaning.

[0025] Working Principle: This embodiment provides an integrated air flotation sedimentation machine for wastewater treatment. During use, an external power supply is used. The air flotation pipeline is inserted into the wastewater in the tank 1 through the assembly port 301. Dissolved air water is injected into the wastewater through the pipeline, forming tiny floating bubbles. These bubbles adhere to suspended solids, forming floating impurities. Based on the liquid level, the motor on the central plate 6 drives the screw 602 to rotate. The screw 602 threadedly drives the adjusting plate 5 in conjunction with the limiting rod 603, achieving relative displacement between the two adjusting plates 5. When the two adjusting plates 5 approach each other, the lower linkage arm 501 drives the lifting cylinder 704 to descend within the bottom cylinder 7. Floating impurities are then sucked up through the material inlet 705 at the lower end of the internal pipe 706 and discharged through the discharge pipe 70. 2. The material is introduced into the storage box 4 for storage. The blade 701 is designed in the shape of a lotus leaf, and the upper surface of the blade 701 has a concave opening. A pressure sensor is provided at the connection between the built-in tube 706 and the lifting cylinder 704. When the blade 701 is in contact with the sewage surface, the pressure sensor detects the signal through buoyancy. The height is adjusted so that the structure places the blade 701 into the lower layer of the sewage surface. At this time, the suspended impurities on the sewage surface correspond to the concave opening of the blade 701, and the liquid level is above the feeding port 705. At this time, the negative pressure pump body 601 is started to generate negative pressure in the storage box 4. Through the negative pressure, the suspended impurities on the sewage surface are screened by the blade 701 and introduced into the storage box 4 for storage from the feeding port 705, the built-in tube 706 and the discharge pipe 702.
