Description

Technical Field

[0001] The utility model relates to the technical field of horizontal flow dissolved air floatation machines, in particular to a horizontal flow dissolved air floatation machine which is convenient for processing suspended matter. Background Art

[0002] Horizontal dissolved air flotation is a device commonly used in the field of water treatment, especially suitable for removing suspended matter, grease and other impurities in water. It uses the release of dissolved gas in water to float suspended particles in the water, thereby achieving solid-liquid separation.

[0003] The horizontal dissolved air flotation machine introduces sewage into the equipment, uses a mixed flocculant to be added to the water pool, and then uses the decompression release of high-pressure dissolved air water to generate tiny bubbles. These bubbles attach to the suspended particles in the water, causing them to float to the water surface and form a scum layer. Subsequently, the scum is collected and removed by a scraper, and the clean water is discharged from the bottom of the equipment.

[0004] The currently used horizontal dissolved air flotation machine is not convenient for collecting and discharging the floating scum during use. When the scum cannot be collected and discharged in a timely and effective manner, the scum will continue to accumulate on the water surface, resulting in a decrease in the processing capacity of the flotation area, affecting the solid-liquid separation effect of the water body, and ultimately affecting the removal effect of suspended matter, resulting in poor water quality.

[0030] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-2 The present invention provides an embodiment of a horizontal flow dissolved air floatation machine for processing suspended matter, comprising:

[0032] The flotation pool 1 serves as the main flotation unit, and a fixed shell 4 is fixedly connected to the front and rear sides of the left end of the flotation pool 1. The outer wall of the left end of the flotation pool 1 is connected to a dissolved air tank 3 through a gas transmission group, so as to infuse the gas in the dissolved air tank 3 into the flotation pool 1. The output end of the dissolved air tank 3 is fixedly connected to a delivery pipe 23, and the other end of the delivery pipe 23 is fixedly connected to the front end of the flotation pool 1 and passes through it.

[0033] Specifically, when the dissolved air tank 3 is opened, the high-pressure air inside is transported to the flotation tank 1 through the delivery pipe 23. This process allows the water in the flotation tank 1 to fully contact with the dissolved gas, thereby generating a large number of dense tiny bubbles in the water.

[0034] Reference Figure 3-Figure 5 , as a connecting shell 2 for scraping and removing slag, the outer wall of the right end of the front connecting shell 2 is fixedly connected to the second motor 6, and the driving end of the second motor 6 is connected to the connecting ring 9 through the moving group, so as to drive the connecting ring 9 to move linearly with the driving force of the second motor 6. The outer wall of the rear end of the connecting ring 9 is rotatably connected to the scraping rod 10, and the rear end of the scraping rod 10 is connected to the sliding rod 14 through the rotating group, so as to convert the linear movement of the scraping rod 10 into circular rotation. The reciprocating screw rod 7 is fixedly connected to the driving end of the second motor 6, and the outer wall of the reciprocating screw rod 7 is provided with a slider 8 The outer wall of the slider 8 is fixedly connected to the inner wall of the connecting ring 9. The rear end of the scraper rod 10 is fixedly connected to the mobile gear 11 and passes through it. The rear end of the scraper rod 10 is rotatably connected to the adapter block 13. The inner wall of the adapter block 13 is slidably connected to the outer wall of the slide rod 14. The outer wall of the mobile gear 11 is meshed with a gear plate 12. The bottom end of the gear plate 12 is fixedly connected to the bottom end of the inner wall of the rear end connecting shell 2. The opposite end of the connecting shell 2 is respectively fixedly connected to the front and rear outer walls of the top of the flotation tank 1. The front and rear ends of the slide rod 14 are respectively fixedly connected to the left and right ends of the inner wall of the rear end connecting shell 2.

[0035] Specifically, when the second motor 6 is started, it drives the reciprocating screw 7 to rotate. Through the rotation of the reciprocating screw 7, the slider 8 is pushed while being sleeved on its outer portion, so that the slider 8 drives the connecting ring 9 to reciprocate. The reciprocating motion of the connecting ring 9 further drives the movement of the foam scraping rod 10. During this process, the foam scraping rod 10 rotates along the gear plate 12 at its bottom and moves stably along the guide of the slide rod 14 through the adapter block 13. This design ensures that the foam scraping rod 10 can maintain stability during rotation and effectively move back and forth, thereby scraping off the foam on the surface of the water in the flotation tank 1.

[0036] Reference Figure 6 and Figure 7 , as a fixed shell 4 for stirring, the outer wall of the top of the fixed shell 4 is fixedly connected to the first motor 5, and the driving end of the first motor 5 is respectively connected to the worm 18 and the chute tube 16 through a gear set, so as to drive the worm 18 and the chute tube 16 to rotate by the driving force of the first motor 5, and the outer wall of the worm 18 is meshed with a worm wheel 19. The left and right ends of the worm wheel 19 are connected to an adapter ring 22 through a reciprocating group, so as to move the adapter ring 22 by the rotating force of the worm wheel 19. The transmission gear 15 is fixedly connected to the driving end of the first motor 5, the worm 18 and the top of the chute tube 16 are all fixedly connected. The transmission gear 15 is meshedly connected, and the left and right ends of the worm wheel 19 are fixedly connected to the eccentric wheel 20, and the opposite end of the eccentric wheel 20 is rotatably connected to the connecting rod 21. The inner wall of the chute tube 16 is slidably connected to the stirring rod 17, and the inner wall of the adapter ring 22 is rotatably connected to the outer wall of the top end of the stirring rod 17, and the bottom end of the worm 18 is rotatably connected to the bottom end of the inner wall of the fixed shell 4.

[0037] Specifically: when the flocculant is stirred, the first motor 5 is started, driving the transmission gear 15 to rotate. The rotation of the transmission gear 15 causes the chute tube 16 and the worm 18 to rotate at the same time. The rotation of the chute tube 16 drives the stirring rod 17 to stir, thereby performing preliminary mixing and homogenization on the flocculant. At the same time, the rotation of the worm 18 drives the worm gear 19 to rotate, and the worm gear 19 further drives the rotation of the eccentric wheel 20. The eccentric wheel 20 drives the movement of the adapter ring 22 through the connecting rod 21, so that the adapter ring 22 drives the stirring rod 17 to move up and down during its rotation. This design enables the stirring rod 17 to move up and down when stirring the flocculant, thereby stirring the flocculant more evenly and comprehensively. Through the up and down movement, the stirring rod 17 can effectively mix the upper and lower layers of the flocculant evenly, ensuring that the entire flocculant reaches a consistent concentration and effect during the stirring process.

[0038] Working principle: When the dissolved air tank 3 is opened, the air inside it is transmitted to the flotation pool 1 through the delivery pipe 23, so that dense bubbles are generated in the aqueous solution in the water pool in the flotation pool 1. When the second motor 6 is started, the second motor 6 drives the reciprocating screw 7 to rotate, so that the reciprocating screw 7 passes through the slider 8 set on its outer sleeve, and the slider 8 drives the connecting ring 9 to move back and forth. When the connecting ring 9 drives the scraping rod 10 to move, the moving gear 11 at the scraping rod 10 moves along the gear plate 12, the moving gear 11 rotates along the gear plate 12, and the adapter block 13 moves along the slide bar 14 to maintain the stability of the scraping rod 10 when it rotates, so that the scraping rod 10 can scrape the foam. When foam is generated, the scraping rod 10 is moved back and forth to scrape off the foam in the water pool in the flotation tank 1, thereby facilitating the device to discharge floating suspended matter. When the flocculant is stirred, the first motor 5 drives the transmission gear 15 to rotate, so that the chute tube 16 and the worm 18 are rotated. When the chute tube 16 rotates, it drives the stirring rod 17 to rotate to stir the flocculant. When the worm 18 rotates, it drives the worm wheel 19 to rotate, so that the worm wheel 19 drives the eccentric wheel 20, so that the connecting rod 21 drives the adapter ring 22 to move, and the adapter ring 22 drives the stirring rod 17 to move while rotating, thereby facilitating the device to move the flocculant up and down and stir the upper and lower layers of flocculant evenly.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
