Embodiment 1
As Fig. 1, the structure of stirred tank provided by the invention, the top of kettle 1 is provided with motor 2, the below of motor 2 is connected on turbine 4 by first connecting rod 3, the top of turbine 4 is suction inlets, and below is outlet, and the below of turbine 4 is also connected with second connecting rod 5, second connecting rod 5 is hollow structure, and the outlet of turbine 4 is connected with second connecting rod 5.The below of second connecting rod 5 is provided with stirrer paddle 6, and the inside of stirrer paddle 6 is also hollow cavity 7, and second connecting rod 5 is also connected with hollow cavity 7, material is thus formed turbine 4 and is connected with hollow cavity 7.In addition, stirrer paddle 6 is provided with opening 8, opening 8 is communicated with hollow cavity 7.
When routine uses stirred tank, if the temperature of feed liquid declines or after discharge opeing, the waste oil of cooling can adhere on paddle, result in these dirts to be not easy to remove, particularly after long-time use, the waste oil layer formed above it is comparatively sticky thick, removes difficulty very big.
At stirred tank of the present invention in use, motor 2 can drive stirrer paddle 6 to rotate by first connecting rod 3, second connecting rod 5, due to second connecting rod 5 being connected with turbine 4, so turbine 4 also can rotate simultaneously, and it can by after the air pressurized in stirred tank, the hollow cavity 7 of press-in blade 6, discharge from opening 8 again, so just can be avoided the oil reservoir forming monoblock on stirrer paddle 6, those skilled in the art know when Residual oil is that it is more easily eliminated in when dividing block.
In one embodiment, as shown in Figure 2, opening 8 is multiple in the quantity of stirrer paddle 6, and is evenly distributed, and the effect of the minimizing waste oil caking that opening 8 so just can be made to realize is average, better effects if during removing.
In another embodiment, as shown in Figures 1 to 3, opening 8 is also provided with shell fragment 9, shell fragment 9 can be that side is connected with opening 8, and the other end is free end.So when the internal high pressure air of hollow cavity 7 is gone out, free end can be made to upspring, air-flow is nuzzled up along the surface of blade, and the removal effect for surface area oil is better.
In another embodiment, as Fig. 3, opening 8 is circular, opening 8 is embedded with shell fragment 9, shell fragment 9 is cut the opening of " ten " font, and when gases at high pressure are gone out, it can make, in four shapes of upspringing in the middle of shell fragment 9, to produce the effect that superficial air tangentially washes away.
At a better embodiment, be as shown in Figure 4, opening 8 is circular, the periphery of shell fragment 9 is provided with four sections of spaced incision sections 10, cut section 10 not to be connected with opening 8, the remainder on the periphery of shell fragment 9 is connected with opening 8, and the radian of the incision section 10 of every section is greater than 45 °.When adopting this structure, can ensure that the flow direction of the pressure-air that shell fragment 9 is discharged is the peripheral direction towards opening 8, and be the surface being tangential to blade, it is better for the removal effect of the long-pending oil of opening 8 periphery.
In another embodiment, dividing plate 13 is also provided with on the top of kettle 1, dividing plate 13 is provided with discharging opening 15, the top of discharging opening 15 is provided with reagent pot 12, the below of dividing plate 15 is provided with rotating disk 14, and rotating disk 14 and dividing plate 15 fit, and rotating disk 14 is fixed on first connecting rod 3, rotating disk 14 is also provided with perforate 16, can be connected with discharging opening 15 when the below of perforate 16 along with discharging opening 15.
For oily waste water carry out dosing resolution process time, by being need to add medicament in waste water, and for some reaction speeds degradation reaction faster, need the amount of the medicament added also can be more, and the speed stirred also needs to accelerate.Under normal circumstances, after improving mixing speed, often very important person improves the speed adding medicament again, and this operational means is comparatively loaded down with trivial details.In order to improve automaticity, need to design a kind of mode that can change medicament according to mixing speed and automatically add speed.As shown in Figure 1 like this, when stirring unlatching, rotating disk 14 can be driven by first connecting rod 3 and rotate, and be placed with reagent in reagent pot 12 above dividing plate 13, perforate 16 on rotating disk 14 goes to after below discharging opening 15, achieve the connection of three of reagent pot 12, discharging opening 15, perforate 16, reagent will fall from reagent pot 12; When mixing speed is faster, the rotary speed of rotating disk 14 will be faster, and the frequency that the three of so reagent pot 12, discharging opening 15, perforate 16 is communicated with will be more, and chemical feeding quantity will be more, achieve the directly proportional automation mechanized operation of chemical feeding quantity and speed of agitator.
In another one embodiment, as Fig. 1, be also provided with funnel 11 in the below of rotating disk 14, one end of funnel 11 is in the below of discharging opening 15, and the other end of funnel 11 is in the import of turbine 4.In the process of operation, reagent can't directly fall from discharging opening 15, but can enter in turbine 4, mixes with pressure-air, then discharges by the opening 8 of blade, makes the reaction of reagent and waste liquid more even.
