Description

Directional removing equipment for pollutants in border-crossing short river reach

Technical Field

The invention belongs to the technical field of water treatment, and particularly discloses directional removing equipment for pollutants in a cross-border short river reach.

Background

Water is the source of life, the key point of production and the basis of ecology, a basin taking water as the core is the foundation of survival, civilized cradle and development of the human society, and the water provides active convenience for the development of cities and human life.

In rainy season, the rainwater can wash the grease and solid floater on the earth's surface into the river of the short river channel, which can lead to more impurities and sundries floating on the water surface, on one hand, the river can be blocked, on the other hand, after the floater in the river of the short river channel sinks into the river along with the river water, the floater can pollute the river, thus causing serious pollution to the water resource.

Disclosure of Invention

The invention aims to provide directional removing equipment for pollutants in a short river reach of a cross border, and the directional removing equipment is used for solving the problem that water resources are seriously polluted when floaters in a river of the short river reach a large river.

In order to achieve the purpose, the basic scheme of the invention is as follows: equipment is got rid of to border-crossing short river reach pollutant orientation, which comprises a frame and a driving mechanism, a serial communication port, be equipped with the absorption portion in the frame, crushing portion and the conveying portion that is used for conveying impurity, the crushing portion of actuating mechanism drive is smashed and is conveyed with conveying portion, crushing portion is including setting up the pair roller in the frame, the pair roller is including last roller and lower roll, the lower roll is located the coaxial disc in the outer position of frame, be connected with branch on the eccentric position of disc, the frame lower part is equipped with the cylinder, the piston rod and the connecting rod of cylinder are articulated, the sub-unit connection of cylinder has the outlet duct that is used for jet-propelled, be equipped with outside one-way conduction's first check valve in the outlet duct, be equipped with the air supplement pipe on the cylinder, be equipped with the second check valve to one-way conduction in the cylinder in the air supplement pipe.

The working principle of the basic scheme is as follows: before pollutants are treated by the strengthening equipment, the rack is fixed above the river surface of a short river reach, the lower parts of the adsorption part and the conveying part are immersed under the water surface, the driving mechanism is started, and the crushing part and the transmission part are driven by the driving mechanism to work; in the water flowing process, the adsorption part adsorbs the grease floating on the water surface; the impurities floating on the water surface are crushed by the crushing part and then transferred out of the machine frame by the conveying part. In the process of the rotation of the roller pair, the lower roller rotates to drive the supporting rod to swing, when the supporting rod swings downwards, the supporting rod pushes the piston to move downwards, the piston moves downwards to push the gas at the lower part of the cylinder barrel to be discharged through the gas outlet pipe and form bubbles underwater, and the bubbles can drive suspended impurities in water to the water surface in the process of moving to the water surface.

The beneficial effect of this basic scheme lies in:

(1) the equipment can adsorb grease impurities on the water surface by using the adsorption part, effectively reduces the grease impurities floating in the short river reach water flow, reduces pollutants in the water and improves the water quality;

(2) the equipment can crush the blocky impurities floating on the water surface, and transfer the crushed impurities out of the river reach through the conveying part, so that the blockage of the river in the short river reach can be prevented;

(3) this equipment is handling and is floating the impurity in-process, can drive the surface of water with the impurity of aquatic suspension through aeration under water, and the adsorption part of being convenient for fully adsorbs and detach the impurity of aquatic.

Further, the conveying part is including rotating the commentaries on classics roller of connection in the frame, and the surface of commentaries on classics roller is equipped with the adsorbed layer of adsorbed grease class impurity, and the commentaries on classics roller both sides all are equipped with the impeller, are connected with the violently pipe parallel with last roller on the outlet duct, violently manage the one side that is located the below of commentaries on classics roller. The contact area between the transverse pipe and water is increased by using the transverse pipe, more air bubbles can be formed when the transverse pipe aerates into the water, and more suspended matters can be brought to the water surface through the air bubbles; when the bubble emits the surface of water in-process, thereby the bubble can push away the impeller and rotate and drive and change the roller and rotate, rotate the roller and can promote impurity on the surface of water to water pressure, floated impurity receives the buoyancy of water after increase with the extrusion force of changeing the roller, help the adsorbed layer like this to adsorb impurity.

Further, the conveying part comprises a fixing plate, two rotating wheels, two rotating shafts, two rotating discs, two connecting rods and a conveying plate, the fixing plate is obliquely arranged on the rack, through holes for the conveying plate to pass in and out are formed in the fixing plate, one end of each connecting rod is hinged to the rotating shaft, the other end of each connecting rod is hinged to the conveying plate, and a belt is connected between the two rotating wheels. When the supporting rod rotates along with the disc, the disc drives the supporting rod to swing, the supporting rod swinging energy drives the conveying plate to swing, the conveying plate swinging energy intermittently conveys sundries, meanwhile, the attached water on the sundries can be reduced, and the sundries can be conveniently subjected to subsequent treatment.

Furthermore, a scraper blade used for cleaning the rotary roller is arranged on the rack, a bent part is arranged at the lower end of the scraper blade, and the bent part is attached to the rotary roller. Can scrape away the impurity that changes the roller surface through the kink, the kink can also be collected impurity, is convenient for to impurity centralized processing.

Furthermore, the scraper extends to the outside of the frame, and the part of the scraper, which is positioned outside the frame, is connected with a collecting box. Through setting up the collecting box, can concentrate the impurity that the scraper blade was got rid of from changeing the roller and collect, be convenient for carry out subsequent processing to the impurity of collecting.

Furthermore, a mounting seat is arranged on the position, between the adsorption part and the crushing part, of the rack, a row of idler wheels are arranged on the mounting seat along the length direction of the upper roller, and an inclined guide plate is arranged on the lower portion of the mounting seat. When the river contains sundries in the length direction along the water flow direction, the sundries can deflect when being pushed onto the roller, and the deflected sundries are transverse and beneficial to crushing.
