Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an air flotation wastewater treatment machine. Background Technology

[0002] With the rapid development of industrialization and urbanization, large amounts of industrial wastewater and domestic sewage containing various pollutants are discharged into the natural environment, causing serious pollution to water resources. Water shortage and pollution problems have increasingly become a global concern. Therefore, effective wastewater treatment technologies are needed to protect water resources and achieve sustainable use of water resources.

[0003] The wastewater to be treated is discharged into the storage tank, a certain amount of chemicals are added and stirred. After stirring, air bubbles are released from the bottom of the wastewater upwards, and smaller debris will float to the top of the water surface. The floating debris can then be removed using a scraper.

[0004] Existing air flotation wastewater treatment machines rely on the flow rate of the wastewater itself to scrape off floating debris, which is relatively slow and lacks the function of increasing the flow rate of floating debris. Therefore, an air flotation wastewater treatment machine is proposed. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This utility model provides an air flotation wastewater treatment machine. It has the following beneficial effects:

[0018] 1. Through the action of the scraping mechanism, air bubbles push the debris to the water surface. When the shaft rotates, it drives two transmission sprockets to rotate simultaneously, which in turn drives the symmetrically distributed transmission chain. This drives multiple fixed blocks evenly distributed on the outer side of the transmission chain to move, thereby moving the rubber scraper. When the rubber scraper moves vertically, it moves the debris floating on the water surface from the far end of the debris storage tank to the storage tank. Under the action of the rubber scraper, the suspended matter is pushed into the storage tank, which can scrape away the floating matter on the surface of the sewage and has the function of removing floating matter from the surface of sewage.

[0019] 2. Through the action of the exhaust mechanism, the height of the slide rod in the T-shaped groove is adjusted according to the highest water level in the sewage storage tank. The slide rod is locked by the locking blocks at different heights, restricting its movement. The exhaust is discharged into the exhaust duct through the air tank. Under the action of the exhaust duct, the floating objects on the water surface are blown towards the rubber scraper, which can accelerate the movement of floating objects and thus speed up the treatment of floating objects.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides an air flotation wastewater treatment machine, including a water storage tank 1, a scraping mechanism 2 on the top of the water storage tank 1, and an exhaust mechanism 3 on the other side of the top of the water storage tank 1.

[0031] The scraping mechanism 2 is symmetrically installed on the fixed plate 201 on the top of the water storage tank 1. A rotating shaft 203 is provided on one side of the two fixed plates 201. A transmission sprocket 204 is symmetrically installed on the outer surface of the rotating shaft 203. A transmission chain 205 is connected to the outer surface of the transmission sprocket 204.

[0032] Specifically, the fixing plates 201 are symmetrically installed on the top of the water storage tank 1 in two sets. When the rotating shaft 203 is driven to rotate, it drives the two transmission sprockets 204 on its outer surface to rotate simultaneously. Each set of fixing plates 201 is provided with a rotating shaft 203, so it can drive the symmetrically distributed transmission chains 205 to perform transmission.

[0033] Multiple fixing blocks 206 are evenly distributed on the outer surface of the transmission chain 205. A support rod 208 is fixedly installed on one side of two fixing blocks 206 facing each other. Limiting strips 209 are symmetrically arranged on one side of the support rod 208.

[0034] Specifically, when the transmission chain 205 is driven, it can drive multiple fixed blocks 206 on its outer side to rotate. When the two transmission chains 205 rotate simultaneously, they can drive the symmetrical fixed blocks 206 to move at the same speed, thus driving the support rod 208 to move. The support rod 208 drives the limiting strip 209 on one side to move. When the two transmission chains 205 are driven simultaneously, the support rod 208 can be kept to move in the vertical direction.

[0035] A rubber scraper 210 is installed on one side of the two limit bars 209 by several bolts. A storage tank 207 is installed on the inner surface of the water tank 1. A motor 202 is fixedly installed on one side of the rotating shaft 203.

[0036] Specifically, when the support rod 208 moves, it drives the rubber scraper 210, which is fixed by bolts, to move. The rubber scraper 210 scrapes the debris floating on the water surface into the debris storage tank 207 for collection. The debris can then be discharged through the drain outlet on the upper side of the water storage tank 1.

[0037] Multiple rubber scrapers 210 are located on top of the waste storage tank 207, and the waste storage tank 207 is adapted to the multiple rubber scrapers 210.

[0038] Furthermore, the operation of the fixed plate 201 is controlled. The fixed plate 201 drives the rotating shaft 203 to rotate, the rotating shaft 203 drives the two transmission sprockets 204 to rotate, each transmission sprocket 204 drives the corresponding transmission chain 205 to drive, the transmission chain 205 drives the multiple fixed blocks 206 on the outside to drive, the fixed blocks 206 drive the support rod 208 to move, the support rod 208 drives the rubber scraper 210 fixed on the opposite side of the two limit bars 209 to move, the rubber scraper 210 pushes the debris floating on the water surface toward the debris storage tank 207, pushes the debris into the debris storage tank 207, and finally the debris is discharged from the pipe above one side of the water storage tank 1.

[0039] Example 2

[0040] Reference Figure 4 , Figure 5 and Figure 6 This is the second embodiment of the present invention, which is based on the previous embodiment and includes a ventilation mechanism 3 that can accelerate the flow rate of floating materials.

[0041] The ventilation mechanism 3 is symmetrically installed on the columns 301 at the top of the water storage tank 1. A sliding rod 302 is movably installed on one side of the two columns 301, and an air outlet 306 is fixedly installed at the bottom of the sliding rod 302.

[0042] Specifically, the air outlet 306 is connected to the air tank on one side of the water storage tank 1 through a pipe. According to the depth of the sewage in the water storage tank 1, the upper and lower positions of the slide bar 302 in the two columns 301 are adjusted. The air in the air tank is blown towards the floating objects on the surface of the sewage through the air outlet 306, which speeds up the flow of the floating objects toward the rubber scraper 210 and improves the treatment efficiency of the floating objects in the sewage.

[0043] A T-shaped groove 303 is provided on one side of the column 301, and springs 304 are evenly distributed inside the column 301. A locking block 305 is provided on one side of the spring 304.

[0044] Specifically, after the slide bar 302 is adjusted to the correct position, the locking block 305 is pushed into the slide bar 302 under the action of the spring 304. After the locking blocks 305 on both sides of the slide bar 302 are engaged in the slide bar 302, the movement of the slide bar 302 is restricted. Depending on the different height positions of the slide bar 302, the locking blocks 305 at different heights are engaged in the slide bar 302.

[0045] The slide bar 302 is slidably connected in the T-shaped groove 303, the locking block 305 is adapted to the slide bar 302, and the air outlet 306 is located on the opposite side of the two columns 301.

[0046] Furthermore, after adjusting the position of the slide bar 302 according to the highest water level in the sewage storage tank 1, the locking block 305 is pushed into the slide bar 302 under the action of the spring 304. After the locking blocks 305 on both sides of the slide bar 302 are locked into the slide bar 302, the movement of the slide bar 302 is restricted. According to the different height positions of the slide bar 302, the locking blocks 305 at different heights are locked into the slide bar 302. The air is vented to the air outlet 306 through the air tank, and the floating objects on the water surface are blown towards the rubber scraper 210, thereby improving the movement of the floating objects.

[0047] Working principle: The water storage tank 1 is equipped with a stirring structure, an exhaust structure, and a sludge removal structure, all of which are existing structures and identical to those disclosed. Wastewater is discharged into the stirring structure, where chemicals are added for stirring. The wastewater flows into the exhaust structure, and through the exhaust port inserted at the bottom of the wastewater, bubbles rise from the bottom to the surface, pushing smaller debris to the surface. At this time, the slide rod 302 is adjusted according to the position of the wastewater surface. After adjustment, under the action of the spring 304, the locking block 305 is pushed into the slide rod 302. After the locking blocks 305 on both sides of the slide rod 302 are engaged, the movement of the slide rod 302 is restricted. Depending on the different height positions of the slide rod 302, the locking blocks 305 at different heights are engaged in the slide rod 302. Exhaust is then vented through the air tank to the air outlet 306, pushing the floating debris on the water surface towards the air outlet 306. The rubber scraper 210 blows, keeping the air outlet 306 in a blowing state. When the floating objects are blown to the bottom of the scraping mechanism 2, the fixed plate 201 is controlled to operate. The fixed plate 201 drives the rotating shaft 203 to rotate, and the rotating shaft 203 drives the two transmission sprockets 204 to rotate. Each transmission sprocket 204 drives the corresponding transmission chain 205 to drive, and the transmission chain 205 drives the multiple fixed blocks 206 on the outside to drive. The fixed blocks 206 drive the support rod 208 to move, and the support rod 208 drives the rubber scraper 210 fixed on the opposite side of the two limit bars 209 to move. The rubber scraper 210 pushes the debris floating on the water surface toward the debris storage tank 207, pushing the debris into the debris storage tank 207. Finally, the debris is discharged from the pipe above one side of the water storage tank 1, and the clean water is discharged from the pipe below one side of the water storage tank 1.
