The both ends of tuber pipe 26 are along the direction slope setting gradually that is close to waste residue collecting pit 3 and are made tuber pipe 26 be the arc, and the wind that makes tuber pipe 26 blow out blows the foam to the middle part of waste residue collecting pit 3, makes the foam can fall in waste residue collecting pit 3, avoids the foam to be blown the outside of waste residue collecting pit 3 and causes pollution and clearance difficulty.
The edges of two sides of each scraper 25 are welded with rectangular scraping edges 251, the two scraping edges 251 are gradually inclined along the direction away from each other, and when the scraper 25 is positioned below the transmission chain 24, the scraping edges 251 extend towards the direction close to the waste residue collecting tank 3. The setting of scraping limit 251 has increased the area of contact of scraper blade 25 with the suspended solid, makes the single volume of scraping the suspended solid more, has improved scraper blade 25 and to the effect of scraping of suspended solid, and the slope setting of scraping limit 251 can play limiting displacement to foam and suspended solid, prevents that foam and suspended solid from flowing out and lead to scraping the effect relatively poor from the edge of scraper blade 25, has further improved the effect of scraping.
A buffer board 28 is installed to the one end that air supporting cell body 1 is close to waste residue collecting pit 3, and screw fixed connection is passed through in air supporting cell body 1 to the one end of buffer board 28, and the other end of buffer board 28 sets up and butt in the edge of waste residue collecting pit 3 along the direction slope gradually that is close to waste residue collecting pit 3. The buffer plate 28 can prevent suspended solids and foams from falling to the ground from the joint of the air flotation tank body 1 and the waste residue collecting tank 3, and pollution is avoided. The slope setting of buffer board 28 can guide suspended solid and the foam that drops on buffer board 28, and guide suspended solid and foam flow prevent that suspended solid and foam from accumulating on buffer board 28 in the waste residue collecting pit 3.
The edge of buffer board 28 both sides respectively vertical welding have a baffle 281, and baffle 281 can be spacing to the suspended solid and the foam that drop on buffer board 28, prevents that suspended solid and the foam that drop on buffer board 28 from flowing subaerially and causing the pollution from the edge of buffer board 28.
One side of the air flotation tank body 1 is provided with a defoaming storage tank 4, a defoaming agent is arranged in the defoaming storage tank 4, the bottom of the defoaming storage tank 4 is communicated with a material pumping pump 41, and the material pumping pump 41 is communicated with a material conveying pipe 42. The top of the mounting frame 2 far away from one end of the waste residue collecting tank 3 is fixedly provided with a circular fixing ring 29 through screws, and one end of the material conveying pipe 42 far away from the material pumping pump 41 penetrates through the fixing ring 29 and extends to the inner side of the air flotation tank body 1. The defoaming agent can play the canceling effect to the foam in the air supporting cell body 1, and when the foam in the air supporting cell body 1 was more, eliminate the foam in the defoaming storage tank 4 through opening the material pump 41 and pump the defoaming agent in into the air supporting cell body 1 through the conveying pipeline 42, avoid the foam too much and spill over the air supporting cell body 1, prevent that ground from receiving the pollution. The fixing ring 29 can fix the material conveying pipe 42, so that the material conveying pipe 42 is firmly fixed on the mounting frame 2, and the condition that the material conveying pipe 42 is shaken by pressure generated when the material conveying pipe 42 sprays the defoaming agent to cause the defoaming agent to be sprayed to the outer side of the air flotation tank body 1 is avoided, and waste is avoided.
The atomizing nozzle 421 is installed at the pipe orifice of the delivery pipe 42, and the atomizing nozzle 421 can make the defoaming agent sprayed from the delivery pipe 42 be in a mist shape, so that the contact area between the defoaming agent and the foam is increased, the defoaming agent and the foam are fully reacted, the foam eliminating effect is improved, the consumption of the defoaming agent can be saved, and the cost is saved.
The implementation principle of the embodiment is as follows: through setting up tuber pipe 26, when the scraper blade 25 moved the one end that air supporting cell body 1 is close to waste residue collecting pit 3, the wind that blows out in the wind gap 261 can blow off the foam on the scraper blade 25, makes scraper blade 25 strike off the front scraper blade 25 surface next time and does not have the foam, makes scraping off of scraper blade 25 next time can strike off more suspended solid, has improved scraping off effect of scraper blade 25. The arrangement of the grating 262 can make the air blown out from the air pipe 26 uniformly distributed, so that the blowing-off effect of the foam is improved, and the scraping effect of the scraper 25 on the suspended matters is further improved. Through setting up defoaming storage tank 4, when the foam in the air supporting cell body 1 is more, eliminate the foam in pumping the air supporting cell body 1 with the defoaming agent, avoid the foam too much and spill over air supporting cell body 1, prevent that ground from receiving the pollution.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
