As shown in fig. 2, a stirring ball 23 is fixedly connected with the bottom of the stirring blade 4 through a pull rope; at the during operation, at stirring paddle 4 pivoted in-process, stirring paddle 4 can drive stirring ball 23 and rotate together, and stirring paddle 4's centrifugal force can drive stirring ball 23 simultaneously and expand to the outside to can make stirring paddle 4 when waste water and medicament stirring mix, stirring paddle 4 and waste water's area of contact is bigger, thereby can make stirring paddle 4 better to waste water and medicament's stirring effect.
Example two
As shown in fig. 8, in comparative example one, another embodiment of the present invention is: a plurality of contact grooves 24 are formed in the side wall of the stirring ball 23; when the stirring ball 23 contacts with the wastewater in operation, the contact groove 24 can increase the contact area of the stirring ball 23 and the wastewater, so that the stirring force is larger when the stirring ball 23 stirs the wastewater, and the stirring effect is better.
During operation, when needs handle waste water, can be with the inside of waste water first leading-in draft tube 6 through water filling port 101, and then the accessible adds medicine subassembly and adds the treatment medicament to the inside of waste water, and then can start first driving motor 2, make first driving motor 2 drive first drive shaft 3 rotate, and then can make first drive shaft 3 drive stirring paddle 4 rotate, and then drive waste water rotation through stirring paddle 4, make waste water and the more even of medicament mixture, can promote waste water downwards simultaneously, simultaneously because stirring paddle 4 rotates in the inside of draft tube 6, because the inside volume of draft tube 6 is less, consequently the stirring can carry out furthest's mixture with less power, thereby can make the energy consumption of stirring less, and then waste water accessible sediment subassembly's inside, carry out sedimentation treatment through the solid waste material of sediment subassembly in to waste water.
After the waste water is mixed with the medicament in the stirring cavity, the waste water enters the sedimentation cavity, the partition plate 13 is used for blocking the water, partial force in the waste water can be eliminated, the waste water is continuously added into the sedimentation cavity, the waste water can enter the arc-shaped bucket through the partition plate 13, the solid waste in the waste water can be enabled to fall down, the waste water can overflow into the water guide channel 12, the waste water can flow into the water outlet 10 through the water guide channel 12 and flow out of the treatment machine body 1 through the water outlet 10, particles which cannot be quickly settled can fall onto the surface of the inclined plate 901 in the process of settling the solid waste in the waste water, then are accumulated on the surface of the inclined plate 901, after the particles are accumulated greatly, the particles can fall onto the bottom position of the sedimentation cavity, after the waste water flows out, the second driving motor 7 can be started, the second driving motor 7 can drive the scraper 9 to rotate through the second driving shaft 8, the adhered solid waste on the arc-shaped bucket can be scraped through the rotation of the scraper 9, and then the electromagnetic valve at the sludge outlet 11 can be started, and the sludge outlet 11 can be opened, so that the solid waste can flow out of the treatment machine body 1 through the sludge outlet 11.
When water rotates along with the stirring blade 4, the water flow impacts on the side wall of the guide plate 14 to generate vibration in the water flow, so that the vibration is transmitted to the water flow, the mixing effect of the wastewater and the medicament can be improved, the guide plate 14 can guide the water flow, tangential flow in the water flow is reduced, and unnecessary energy consumption can be reduced.
At first drive shaft 3 pivoted in-process, can drive rotation board 15 together and rotate, and then after the liquid outlet hole of rotation board 15 removes the position department of liquid outlet, the inside medicament accessible liquid outlet that stores of medicine storage chamber 16 flows, and then flow into the inside of annular dosing pipe 5, and flow out through annular dosing pipe 5, through the rotation of rotation board 15, and then make the structural design that the medicament flows out, can make the outflow and the outflow time of medicament more even, simultaneously through handling the restriction of organism 1 to rotation board 15, can make first drive shaft 3 in the circumstances of the slope of appearing less of pivoted in-process, thereby can make the rotation of first drive shaft 3 more stable.
After the first driving motor 2 stops working, the spring can push the push rod 18, and then the push rod 18 pushes the first driving shaft 3 through the reset groove 19, so that the first driving shaft 3 stays at the position where the liquid outlet and the liquid outlet are misplaced, and the situation that the medicament continuously flows out after the equipment stops working can be effectively avoided.
When the push rod 18 pushes the reset groove 19, and then the first driving shaft 3 is reset, the sliding friction between the push rod 18 and the reset groove 19 can be changed into rolling friction by the rotation of the rolling wheel 20, so that the friction force between the push rod 18 and the reset groove 19 is smaller, the abrasion between the push rod 18 and the reset groove 19 is smaller, meanwhile, when the rolling wheel 20 drives the push protruding block 21 to rotate together, the push rod 18 can be pushed by the push of the push protruding block 21 in the rotating process of the rolling wheel 20, and then the rolling wheel 20 can be impacted on the side wall of the reset groove 19 by the push of the spring, so that vibration is generated in the reset groove 19, and after the vibration is conducted into waste water by the reset groove 19, the vibration can promote the mixing of the waste water and the medicament, so that the mixing effect is better.
When waste water enters the stirring cavity through the water filling port 101, the diversion trench 22 formed in the top of the annular dosing tube 5 can conduct diversion on water flow in the top of the annular dosing tube 5, so that residual waste water in the top of the annular dosing tube 5 is less.
When stirring paddle 4 stirs waste water and medicament, stirring paddle 4 can drive waste water downstream, and stirring paddle 4 that a plurality of arrangements set up can effectually avoid stirring dynamics inadequately in the rivers that are farther with stirring paddle 4, leads to stirring effect not good condition to appear.
In the process of rotating the stirring blade 4, the stirring blade 4 can drive the stirring ball 23 to rotate together, and meanwhile, the centrifugal force of the stirring blade 4 can drive the stirring ball 23 to spread outwards, so that the contact area between the stirring blade 4 and the wastewater is larger when the stirring blade 4 is used for stirring and mixing the wastewater and the medicament, and the stirring effect of the stirring blade 4 on the wastewater and the medicament is better.
