The working principle of the invention is as follows:
Firstly, sewage is discharged into a filtering space 3 in a treatment box 1 through a water inlet pipe, a first motor 73 and an electromagnet 75 are started, the permanent magnet is driven to synchronously rotate in the process of driving a rotating rod 74 to rotate by the first motor 73 through the strong attraction of the electromagnet 75 and the permanent magnet, a protective shell 76 is driven to synchronously rotate, a connecting rod 77 is driven to synchronously rotate, a collecting frame 71 is driven to rotate by the connecting rod 77, impurities on a filter plate 2 are cleaned through the collecting frame 71, the impurities enter the collecting frame 71, and the impurities cannot float out in the collecting frame 71 due to the reaction force of polluted water due to the continuous rotation of the collecting frame 71;
As impurities are collected, the filtering holes 79 are blocked by the impurities in the collecting frame 71, so that the resistance of the collecting frame 71 is increased, the rotating speed of the rotating rod 74 is faster than that of the collecting frame 71, the rotating rod 74 drives the protecting shell 76 and the shifting plate 711 to slowly rotate to the rear side (the rear side in the rotating direction) of the collecting frame 71 due to the rotating speed difference of the rotating rod 74 and the collecting frame 71, the shifting plate 711 is further contacted with the baffle 725, the baffle 725 is enabled to overturn towards the opening of the collecting frame 71, and the pressure sensor is arranged in the baffle 725, so that after the baffle 725 is contacted with the collecting frame 71, the pressure sensor transmits an electric signal to the PLC, and then the PLC controls the electromagnetic sheet to electrify the electromagnetic sheet, controls the first electric telescopic rod 723 to push the blocking block 724 to extend outwards, and the baffle 725 adsorbs the baffle 725, so that the baffle 725 blocks the inlet of the collecting frame 71, after the collecting frame 71 rotates, the pressure sensor in the blocking block 724 sends an electric signal to the PLC, and then the PLC controls the jet pump 721 to start, the external sewage is pumped by the hydraulic pump, and then the sewage is discharged from the rear side to the water pump, and the impurity is pushed forward by the reverse force of the hydraulic pump 721 when the water pump is pushed forward by the action of the water jet pump according to the third law of the interaction force of the water jet pump, and the impurity is discharged forward;
After the hydraulic jet pump 721 is started for a certain period of time (the period of time is the period of time when the hydraulic jet pump 721 is about to push out impurities after being tested in advance, and the purpose is to prevent the sewage from being discharged from the discharge hole 726 in advance, although the sewage is discharged along with a little, but the sewage is negligible) the second electric telescopic rod 728 is started to drive the plugging block 729 to move upwards through the second electric telescopic rod 728, so that the discharge hole 726 leaks out, the impurities are discharged onto the extrusion plate 83 in the first liquid storage tank 81 through the discharge hole 726, the extrusion plate 83 is extruded downwards through the gravity of the impurities, and the flocculating agent is extruded into the temporary storage shell 85 for later use;
the opening and closing time of the first electromagnetic valve and the second electromagnetic valve are tested in advance, so that sewage in the flocculation space 5 and the disinfection space 6 can be treated, wherein the opening time of the first electromagnetic valve is always later than that of the second electromagnetic valve, the reason is that the treated sewage in the disinfection space 6 needs to be discharged through the water suction pump 14, then the sewage in the flocculation space 5 can be treated in the disinfection space 6, then the sewage in the pre-storage space 4 can be discharged into the flocculation space 5, the sewage cannot enter the filtering space 3, the sewage in the pre-storage space 4 can be continuously discharged after being discharged into the flocculation space 5, the time interval in the above is tested in advance, the upper limit value of the sewage can be treated is taken, and the water inlet pipe is controlled by the PLC, the water inlet pipe is closed after being opened for a certain time, and the opening time is consistent each time, so that the sewage amount treated each time is consistent can be ensured.
Since the sewage filtered in the filtering space 3 is stored in the pre-storing space 4, the sewage in the pre-storing space 4 is all filled in the flocculating space 5, and the more the impurities generated by filtering, the more the finer impurities remain in the sewage with edges, because when a large amount of impurities exist in the sewage, the impurity content of various sizes in the sewage is higher, the larger impurities are trapped by the filtering plate 2, but for the finer impurities, more parts still possibly can enter the pre-storing space 4 through the pores of the filtering plate 2, so that the more the impurities generated by filtering, the greater the moving distance of the extruding and squeezing plate 83, and the more the flocculating agent enters the temporary storage shell 85.
The first electromagnetic valve is controlled by the PLC to be opened, so that sewage in the pre-storing space 4 enters the flocculation space 5, the metering electromagnetic valve is opened, the flocculation agent enters the flocculation space 5, meanwhile, the second motor 89 is controlled by the PLC to be started, the stirring rod 810 and the stirring plate 811 are driven to rotate by the second motor 89, the sewage is fully contacted with the flocculation agent, the effective components in the flocculation agent can be quickly and uniformly dispersed into the sewage, and fully contacted with impurities in the sewage and react, so that the time required by flocculation reaction is greatly shortened, and impurity particles are mutually aggregated to form larger flocculation (the prior art);
the amount of flocculation entering the flocculation space 5 is calculated through the PLC controller, the foaming amount required to be discharged into the flocculation space 5 is calculated through the calculated amount of flocculation, the reason is that the more impurities are generated by filtration, the higher the impurity content of various sizes in sewage is, the more tiny impurities enter the pre-storage space 4 after preliminary filtration are, the pollution degree of the sewage is higher, the water quality is poorer, more flocculation agent is required for treatment so as to achieve better flocculation effect, the impurities are coagulated into larger flocculation, the flocculation process is the basis of the subsequent foaming process (the flocculation process is the basis of the subsequent foaming process, mainly because the flocculation agent can lead tiny impurity particles in the sewage to be aggregated into larger flocculation, the particle size is increased, the surface property of the impurity particles is changed, the amount of the flocculation agent is more easily combined with bubbles), the state and the amount of the flocculation agent after the flocculation agent can influence the foaming effect, the requirement of the flocculation agent can be further based on the impurity content is further inferred, the requirement of the flocculation agent is required to be controlled in the pre-foaming structure after the foaming agent is completely conveyed to the water pump (the foaming process is controlled in the pre-foaming space after the water pump is completely tested by the PLC).
The foaming agent is mixed with the flocculated sewage through the stirring rod 810 and the stirring plate 811, the foaming agent can be fully contacted with the water and dispersed in the water through stirring, the surface tension of the water is reduced, air is more easily formed into bubbles in the water, after the bubbles are generated, the bubbles can interact with flocculated impurities in the flocculated sewage, due to factors such as the surface tension, the flocculated impurities can be attached to the surface of the bubbles or are wrapped by the bubbles to form an air-solid combination, the density of the bubbles is smaller than that of the water, the attached flocculated impurities can float to the surface of the sewage together, then the fourth electric telescopic rod 94 is controlled by the PLC controller to extend upwards, the infrared transmitter 95 is driven to move upwards in the process of transmitting infrared rays, the conducting sheet 96 is driven to move on the resistive plate 97, the current passing through the sliding rheostat is changed, the infrared rays pass through the sewage and then irradiate on the infrared receiver 93, when the infrared intensity received by the infrared receiver 93 changes, the infrared receiver is in the foam part, the foam is reflected and the infrared receiver, the infrared receiver is in the air-solid combination, the density is smaller, the current is recorded, the current is continuously calculated to be transmitted to the top end of the infrared receiver module when the current is changed, and the current is continuously recorded to be larger and the current is continuously transmitted to the top end of the infrared transmitter 95 according to the current which is continuously moved to the current.
After the recording is completed, the gas-liquid mixed pumping pump 815 and the third electric telescopic rod 816 are controlled by the PLC controller to be started, the pumping plate 814 is driven to rotate by the rotation of the stirring rod 810, air in the pumping plate 814 is pumped out by the gas-liquid mixed pumping pump 815, then bubbles are pumped out in a rotating mode, meanwhile, the third electric telescopic rod 816 pushes the pumping plate 814 downwards to slowly move downwards, the downwards moving distance of the pumping plate 814 is calculated according to the detected current at the liquid level position, and after the detected current reaches the liquid level position, the gas-liquid mixed pumping pump 815 is turned off, and the third electric telescopic rod 816 is reset.
The sewage generally contains a large amount of organic pollutants, microbial metabolites, residual surfactants and the like, and many of these substances have surface activity, can reduce the surface tension of water, enable air to be easily dispersed in water to form bubbles, and further generate more bubbles, so that the more impurities in the sewage are, the more bubbles are, the stronger infrared rays are needed for disinfection, the record is made of the bubble thickness of the sewage treated at this time, and when the sewage treated at this time enters the disinfection space 6, the power of the ultraviolet lamp ring 910 is controlled by the PLC controller, and the thicker and more bubbles are needed, so that the ultraviolet irradiation intensity is larger.
The above-described sewage treatment process can be roughly classified into three stages:
The first stage treatment, in which sewage is discharged into the filtering space 3 in the treatment box 1 through the water inlet pipe, the first motor 73 and the electromagnet 75 are started to drive the collecting frame 71 to rotate, and impurities on the filter plate 2 are cleaned and collected. When the impurity blocks the filtering holes to increase the resistance of the collecting frame 71, the rotation speed difference triggers a series of actions, the hydraulic jet pump 721 pushes out the impurity, the impurity is discharged into the first liquid storage tank 81 through the discharging hole 726, and the flocculating agent is extruded into the temporary storage shell 85.
Secondary treatment, namely storing the filtered sewage in the pre-storing space 4 and discharging the sewage into the flocculation space 5 in sequence. The PLC controller controls and opens the first electromagnetic valve and the metering electromagnetic valve to enable sewage to be mixed with flocculating agent, the second motor 89 drives stirring to accelerate flocculation reaction, then the amount of foaming agent is calculated according to the amount of flocculating agent, the foaming agent is conveyed by the infusion structure, and the thickness of bubbles is detected through infrared rays after stirring and mixing.
Three stages of treatment, the PLC controls the power of the ultraviolet lamp ring 910 according to the thickness of the bubbles. The gas-liquid mixing pump 815 and the third electric telescopic rod 816 are matched, the air bubbles are rotationally pumped out, and the ultraviolet disinfection is carried out on the sewage entering the disinfection space 6, so that the treatment is completed.
