Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a micro-nano bubble high-efficiency flotation machine. Background Art

[0002] Micro-nano bubble high-efficiency flotation machine is a device that uses micro-nano bubble technology to treat wastewater. It has the functions of solid-liquid separation and oil removal and is widely used in water treatment, aquaculture and other fields. Micro-nano bubble high-efficiency flotation machine combines advanced micro-nano technology with coagulation technology to effectively remove suspended matter and grease in water by generating tiny bubbles with diameters at the micron and nanometer level.

[0003] The flotation machine consists of a flotation tank, a dissolved air system, a pressurization system, a scraping system and other main equipment. The scraping system includes one or more scrapers, which are installed around the periphery of the flotation tank and can move slowly along the tank wall. The design of the scraper matches the shape of the tank wall to ensure that the scum can be effectively scraped off. The drive mechanism is usually an electric motor, which can be continuous or intermittent.

[0004] During the sewage treatment process, the scraper constantly pushes the scum to move, and a large amount of impurities are easily attached to the surface. The contamination of the scraper not only reduces the cleaning effect, but may also cause unstable operation of the equipment and even require frequent shutdown for cleaning and maintenance, affecting the sewage treatment efficiency. In addition, due to the large size of the flotation tank, manual cleaning is also inconvenient. Summary of the invention

[0005] The purpose of the present invention is to provide a micro-nano bubble high-efficiency flotation machine to solve the following technical problems: a large amount of impurities are easily attached to the scraper surface, which not only reduces the cleaning effect, but also may cause unstable operation of the equipment and even require frequent shutdown for cleaning and maintenance.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A micro-nano bubble high-efficiency flotation machine, comprising an air flotation tank and two mounting plates respectively fixed on both sides of the air flotation tank, a conveyor belt is installed between the two mounting plates, a plurality of rotatable scrapers are evenly installed on the surface of the conveyor belt, a scraper plate is fixed between the two mounting plates, the scraper plate has a right triangle cross section, and a scraper opening is provided on the scraper plate, a receiving plate with an L-shaped cross section is fixed on one side of the scraper plate, and a cleaning mechanism is also provided between the two mounting plates for cleaning impurities on the receiving plate;

[0008] The scraper is symmetrically installed with mounting blocks on one side close to the conveyor belt, a connecting shaft is arranged between the two mounting blocks, and connecting blocks are rotatably installed at the ends of the two connecting shafts away from each other, and the connecting blocks are fixed on the surface of the conveyor belt, and a torsion spring is connected between the connecting block and the mounting block on the same side.

[0009] As a further solution of the present invention: a feed opening is provided on the top of the two mounting plates, the cleaning mechanism includes two U-shaped plates respectively fixed on the two mounting plates, and the positions of the U-shaped plates correspond to the feed openings, mounting rods are fixed on the side walls of the two U-shaped plates that are away from each other, a reciprocating screw is rotatably installed between the two mounting rods, a moving block is threadedly connected to the reciprocating screw, and a pushing plate is fixed to the bottom of the moving block.

[0010] As a further solution of the present invention: a first pulley is installed at one end of the reciprocating screw, a second pulley is installed at one end of the conveyor belt driving shaft passing through the mounting plate, and a belt is connected between the first pulley and the second pulley.

[0011] As a further solution of the present invention: a collecting box is arranged on the side walls of the two mounting plates which are away from each other, and the collecting box is located below the discharge port.

[0012] As a further solution of the present invention: a fixed block is symmetrically arranged at the bottom of the U-shaped plate, a first guide rod is fixed on the fixed block, a sliding sleeve is slidably connected to the first guide rod, an iron scraper is fixed between the two sliding sleeves, two second guide rods are fixed on the side wall of the U-shaped plate, magnets are movably arranged on the two second guide rods, and push blocks are fixed on both sides of the movable block.

[0013] As a further solution of the present invention: a first spring is sleeved on the first guide rod, a second spring is sleeved on the second guide rod, and the second spring is located between the U-shaped plate and the magnet.

[0014] Beneficial effects of the present invention:

[0015] (1) The present invention arranges a rotatable scraper on the surface of the conveyor belt. The side of the scraper that pushes the scum to move is more likely to be attached with impurities. When the conveyor belt drives the scraper to run continuously or intermittently, the scraper will pass through the scraper plate. Since the scraper plate is fixed and tilted, the scraper plate can scrape off the impurities attached to the scraper plate without stopping the machine for cleaning, thereby ensuring the sewage treatment efficiency.

[0016] (2) The present invention provides a feed port and a cleaning mechanism. As the amount of impurities on the receiving plate increases, the cleaning mechanism can be used to clean the impurities on the receiving plate, thereby preventing excessive impurities from falling onto the conveyor belt and ensuring the scraping effect of the impurities.

[0017] (3) The present invention provides a first guide rod, an iron scraper, a second guide rod, a magnet, a push block and other structures. When the push plate is cleaning the material on the receiving plate, impurities will also adhere to the surface. The iron scraper can automatically clean the impurities attached to the push plate. The operator only needs to maintain the iron scraper regularly without stopping the machine, which will not affect the sewage treatment efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

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.

One end of each of the conveyor belts 3 is rotatably mounted with a connecting block 7, and the connecting block 7 is fixed to the surface of the conveyor belt 3, and a torsion spring 10 is connected between the connecting block 7 and the mounting block 9 on the same side; the conveyor belt 3 is used to drive the scraper 4 to move continuously or intermittently, and the scraper 4 pushes the scum, and the continuously moving scraper 4 will pass through the scraper plate 5 in sequence. When the scraper 4 contacts the scraper plate 5, since the scraper 4 can rotate and the scraper plate 5 is fixed, the scraper 4 is forced to rotate with the connecting shaft 8 as the center, and at the same time, the torsion spring 10 is twisted by force, and the scraper plate 5 scrapes off the impurities on the surface of the scraper 4, and the impurities gradually move to the receiving plate 6 through the scraping port. When the scraper 4 is separated from the scraper plate 5 and the receiving plate 6, it is automatically reset under the action of the torsion spring 10.

[0029] See also Figure 4-5, the tops of the two mounting plates 2 are provided with a feed opening 16, the cleaning mechanism includes two U-shaped plates 11 respectively fixed on the two mounting plates 2, and the position of the U-shaped plates 11 corresponds to the feed opening 16, and the side walls of the two U-shaped plates 11 are fixed with mounting rods 12 away from each other, and a reciprocating screw 13 is rotatably installed between the two mounting rods 12, and a moving block 14 is threadedly connected to the reciprocating screw 13, and a push plate 15 is fixed to the bottom of the moving block 14; a first pulley is installed at one end of the reciprocating screw 13, and a second pulley is installed at one end of the driving shaft of the conveyor belt 3 through the mounting plate 2, and a belt is connected between the first pulley and the second pulley; the two mounting plates 2 are away from each other The side walls are provided with collecting boxes 17, and the collecting boxes 17 are located below the discharge port 16; in order to prevent excessive accumulation of impurities on the receiving plate 6, the reciprocating screw 13 will rotate when the conveyor belt 3 is started. When the reciprocating screw 13 rotates, it drives the moving block 14 and the pushing plate 15 to move, and pushes the impurities collected on the receiving plate 6. When the pushing plate 15 moves to one end of the reciprocating screw 13, the impurities are pushed into the collecting box 17 through the discharge port 16, and then the pushing plate 15 continues to move toward the other end of the reciprocating screw 13 for uninterrupted cleaning. It is worth mentioning that the length of the reciprocating screw 13 is greater than the distance between the two mounting plates 2, which makes it more convenient to push the impurities off.

[0030] See also Figure 4 and Figure 6 A fixed block 19 is symmetrically arranged at the bottom of the U-shaped plate 11, a first guide rod 20 is fixed on the fixed block 19, a sleeve 21 is slidably connected to the first guide rod 20, an iron scraper 22 is fixed between the two sleeves 21, two second guide rods 23 are fixed on the side wall of the U-shaped plate 11, a magnet 24 is movably arranged on the two second guide rods 23, a push block 18 is fixed on both sides of the moving block 14, a first spring 25 is sleeved on the first guide rod 20, a second spring 26 is sleeved on the second guide rod 23, and the second spring 26 is located between the U-shaped plate 11 and the magnet 24; in order to avoid pushing the material There are many impurities attached to the plate 15. When the push plate 15 moves to one end of the reciprocating screw 13, the push block 18 on the moving block 14 will push the magnet 24 to move, so that the magnet 24 is separated from the iron scraper 22, and the iron scraper 22 falls freely. At this time, the push plate 15 just moves to the end of the reciprocating screw 13, and the iron scraper 22 cleans one side of the push plate 15 when it falls. Similarly, when the push plate 15 moves to the other end of the reciprocating screw 13, the other side of the push plate 15 can be cleaned. The operator only needs to perform regular maintenance on the iron scraper 22 without stopping the machine, thereby ensuring the sewage treatment efficiency.

[0031] The working principle of the present invention is as follows: the conveyor belt 3 is used to drive the scraper 4 to move continuously or intermittently, and the scraper 4 pushes the scum. The continuously moving scraper 4 will pass through the scraper plate 5 in sequence. When the scraper 4 contacts the scraper plate 5, since the scraper 4 can rotate and the scraper plate 5 is fixed, the scraper 4 is forced to rotate with the connecting shaft 8 as the center of the circle, and the torsion spring 10 is twisted by force, and the scraper plate 5 scrapes the impurities on the surface of the scraper 4. The impurities gradually move to the receiving plate 6 through the scraping port. When the scraper 4 is separated from the scraper plate 5 and the receiving plate 6, it can automatically reset under the action of the torsion spring 10 and continue the subsequent work.

[0032] In order to prevent excessive accumulation of impurities on the receiving plate 6, the conveyor belt 3 will cause the reciprocating screw 13 to rotate when it is started. When the reciprocating screw 13 rotates, it drives the moving block 14 and the push plate 15 to move, and pushes the impurities collected on the receiving plate 6. When the push plate 15 moves to one end of the reciprocating screw 13, the impurities are pushed into the collection box 17 through the discharge port 16, and then the push plate 15 continues to move to the other end of the reciprocating screw 13 for uninterrupted cleaning.

[0033] When the push block 18 gradually moves away from the magnet 24, the magnet 24 automatically resets under the action of the second spring 26, and the iron scraper 22 contacts the first spring 25 and keeps jumping when it falls. When the magnet 24 resets, it continues to adsorb the iron scraper 22, which is convenient for the next work.

[0034] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
