For convenience of description, in this embodiment, two water outlets are defined as a first water outlet 212 and a second water outlet 213, similarly, two stirring tanks are defined as a first stirring tank 31 and a second stirring tank 32, the first stirring tank 31 is connected to the first water outlet 212, the second stirring tank 32 is connected to the second water outlet 213, a valve on the first stirring tank 31 is denoted as a first valve 51, and a valve on the second stirring tank 32 is denoted as a second valve 52.
The draft tube 21 is further provided with a switch member, the switch member includes a first position and a second position, in the first position, the switch member closes only one of the two water outlets, for example, closes the first water outlet 212, and at this time, the second water outlet 213 is opened;
in the second position, the switch only closes the other of the two water outlets, namely the second water outlet 213, and at the same time, the first water outlet 212 is opened; the switch member is operative to alternate between a first position and a second position, the switch member being shown in a second position in the schematic view of fig. 2.
When the switch is switched to the first position, the second water outlet 213 is opened, the first water outlet 212 is closed, the mixed liquid in the draft tube 21 is only discharged into the second stirring tank 32 through the second water outlet 213, when the amount of sewage in the second stirring tank 32 reaches a predetermined amount, the second stirring tank 32 starts to stir (mainly by the stirring rod), after stirring for a certain time, the switch is switched to the second position (at this time, the first stirring tank 31 starts to feed water), the second stirring tank 32 stops stirring, the second valve 52 is opened, the mixed liquid of sewage in the second stirring tank 32 is discharged into the treatment tank 1, when the amount of sewage in the second stirring tank 32 is not much, the second valve 52 is closed, and at this time, one flow of the second stirring tank 32 is completed to wait for the next flow to start;
in the above process, when the switch is switched to the second position, the first water outlet 212 is opened, the second water outlet 213 is closed, the mixed liquid in the draft tube 21 is discharged into the first stirring tank 31 through the first water outlet 212, the process of the first stirring tank 31 is started, that is, when the amount of wastewater in the first agitation tank 31 reaches a predetermined amount, the first agitation tank 31 starts agitation, and after the agitation for a certain period of time, the switch member is switched to the first position again (at this time, the sewage in the draft tube 21 is discharged into the second stirring tank 32 again to repeat the above steps for the second flow), and the first stirring tank 31 stops stirring, and the first valve 51 is opened to discharge the sewage in the first agitation tank 31 into the treatment tank 1, when the sewage in the first agitation tank 31 is almost discharged, the first valve 51 is closed, and the first agitation tank 31 completes one process to start the next process.
The operation is circularly and alternately carried out, so that the two stirring tanks can be alternately stirred for use, the two stirring tanks can independently operate, and the two stirring tanks cannot generate interference; therefore, the mode that the two stirring tanks are used alternately is adopted in the scheme, so that liquid can be normally fed without stopping the machine, namely, sewage and disinfectant can be continuously discharged into the guide flow pipe 21 in the whole process; suppose only set up a agitator tank, at this moment, when the agitator tank is full of liquid, need stop to discharge into sewage and antiseptic solution in the guide tube 21, only can carry out next operation flow after the antiseptic solution in the agitator tank has discharged, so be equivalent to whole process and need constantly shut down and operate, the agitator tank is full once, stops once, so greatly reduced efficiency undoubtedly.
It should be noted that the present embodiment can be performed by using two stirring tanks to alternatively operate, which mainly depends on the structures of the flow guide tube 21, the dosing tube 22 and the flow channel; because the disinfectant is added to the continuously flowing sewage continuously, the proportion of the sewage to the disinfectant in the mixed liquid formed in the diversion pipe 21 is approximately similar in the whole process, in other words, as long as the discharge speed and the dosing speed of the sewage to the diversion pipe 21 are controlled, the proportion of the sewage to the disinfectant in unit time in the diversion pipe 21 is approximately the same, the proportion of the sewage to the disinfectant in the mixed liquid finally discharged into the two stirring tanks is approximately similar, and thus the mixed liquid finally introduced into the treatment tank 1 can be mixed more uniformly.
If there is no pre-mixing structure such as the flow guide tube 21, the chemical feeding tube 22, and the flow channel, even if there are two stirring tanks, because there is no uniform mixing in the front, the ratio of the disinfectant can be greatly different, in other words, the ratio of the disinfectant in the mixed liquid in one stirring tank is larger, and the ratio of the disinfectant in the other stirring tank is smaller, when the two stirring tanks are discharged into the treatment tank 1, the disinfectant is not uniform in the whole mixed liquid in the treatment tank 1, and it is still necessary to continue to stir in the treatment tank 1, so that the disinfectant is uniformly dispersed.
The specific structure of the switch piece is as follows: as shown in fig. 2, the switch member includes a plunger 261 movably inserted into the fluid guide tube 21 and a motor 262 for driving the plunger 261 to rotate, the motor 262 is disposed on the lower sealing plate 25, the plunger 261 is in a cylindrical structure and is matched with the interior of the fluid guide tube 21, wherein a notch 2611 is formed on a side wall of one side of the plunger 261, in the first position and the second position, an outer peripheral wall of the plunger 261 shields one of the water outlets, and the other water outlet is communicated with the interior of the fluid guide tube 21 through the notch 2611.
Thus, in the first position, the notch 2611 faces the second water outlet 213, and at this time, the second water outlet 213 is communicated with the inside of the draft tube 21 through the notch 2611, that is, opened, and the mixed liquid formed in the draft tube 21 flows to the second water outlet 213 through the notch 2611; meanwhile, the outer peripheral wall of the plunger 261 abuts against the first water outlet 212 to form a sealing effect on the first water outlet 212, namely, to seal the first water outlet 212; when the plunger 261 is driven by the motor 262 to rotate 180 ° to the second position, the cut-out 2611 rotates with the plunger 261 to face the first water outlet 212, at this time, the first water outlet 212 is communicated with the interior of the draft tube 21 through the cut-out 2611, and the second water outlet 213 is closed by the outer peripheral wall of the plunger 261.
The use method of the device comprises the following steps:
s1, controlling the switch to move to switch the switch to the first position, wherein the second water outlet 213 is opened and the first water outlet 212 is closed; and the valves on both agitator tanks are closed, i.e., the first valve 51 on the first agitator tank 31 and the second valve 52 on the second agitator tank 32 are closed simultaneously.
S2, pumping sewage into the guide pipe 21 through the water inlet 211 by using a water pump, pumping disinfectant into the dosing pipe 22 by using a dosing pump, enabling the sewage to flow in the flow channel, spraying the disinfectant into the flow channel through the dosing pipe 22 by using the pesticide spraying piece, mixing the disinfectant and the sewage in the flow channel to form a mixed solution, and then guiding the mixed solution into the stirring tank corresponding to the water outlet through the unsealed water outlet, namely enabling the mixed solution to flow into the second stirring tank 32 through the second water outlet 213.
S3, when the liquid level in the stirring tank reaches a preset height, controlling the switch to the second position and starting the stirring tank to stir, stopping stirring after stirring for a period of time, and opening a valve of a drain pipe of the stirring tank to lead sewage in the stirring tank into the treatment pool 1; when the sewage in the stirring tank descends to a certain height, the valve on the stirring tank is closed, and the method comprises the following specific steps:
when the liquid level in the second stirring tank 32 reaches a predetermined height, the position of the switch is switched to a second position, the first water outlet 212 is opened, the second water outlet 213 is closed, the mixed liquid in the draft tube 21 is discharged into the first stirring tank 31 through the first water outlet 212, and the liquid feeding of the first stirring tank 31 is started at the moment, and the liquid feeding of the second stirring tank 32 is stopped.
When the switch member is switched, the second stirring tank 32 is started, and at the moment, the second stirring tank 32 starts to stir, so that the mixed liquid in the second stirring tank is stirred and mixed again, and the mixing effect is further improved; after stirring for a period of time, the second stirring tank 32 stops stirring, and the second valve 52 is opened, at this time, the sewage in the second stirring tank 32 is gradually discharged into the treatment tank 1, so as to empty the second stirring tank 32, when the sewage in the second stirring tank 32 is lowered to a certain height or is discharged, the second valve 52 is closed, at this time, the discharge pipe of the second stirring pipe is cut off, so that the second stirring tank 32 is used for the next process.
In step S3, when the switch is switched to the second position, the mixed liquid in the flow guide tube 21 is introduced into another mixing tank through another water outlet, that is, the mixed liquid is discharged into the first mixing tank 31 through the first water outlet 212, the above process is repeated, when the liquid level in the first mixing tank 31 reaches a predetermined height, the switch is controlled to be switched to the first position again and the first mixing tank 31 is started to start mixing, after a period of mixing, the first mixing tank 31 is closed to stop mixing, and the first valve 51 of the first mixing tank 31 is opened to introduce the sewage in the first mixing tank 31 into the treatment tank 1; when the sewage in the first stirring tank 31 falls to a certain height, the valve on the first stirring tank 31 is closed, so that the first stirring tank 31 is used for the next process.
The above steps are repeated in a circulating way, so that the liquid can be alternately fed into the two stirring tanks in a circulating way for stirring.
