In the process that the storage bin 31 and the rotating bin 33 move down to the bottom of the treatment tank 1, the rotating bin 33 does not rotate, and a plurality of mixing bins 331 are in a state of being communicated with the outside through the water inlet pipe a41 or the water inlet pipe b42, and are also in a state of being separated from the outside by the mixing bins 331, sewage flows into the mixing bins 331 which are communicated with the outside, and the mixing bins 331 which are separated from the outside maintain a cavity state.
It should be further noted that, the mixing chamber 331 is in a sealed state after a certain period of time, and a certain distance exists between the water inlet channel 3311 and the mixing chamber 331, so that the top space of the mixing chamber 331 is not filled with water.
It should be noted that the water inlet pipe a41 and the water inlet pipe b42 are not simultaneously communicated with one mixing bin 331, and when the mixing bin 331 for subsequent water inlet rotates to be aligned with the discharging hole 311, the flocculant falling into the mixing bin 331 does not overflow sewage into the storage bin 31.
Further, as shown in fig. 2, the adding device 4 further includes a shroud 45 fixedly connected to the storage bin 31 and configured to be installed on the water inlet pipe a41 and the water inlet pipe b42, where the shroud 45 is closely attached to the rotating bin 33 and can seal the water inlet tank 3312.
The shroud 45 seals the water inlet port 3312, and the mixing chamber 331 is communicated with the outside only when the water inlet port 3312 is aligned with the water inlet pipe a41 and the water inlet pipe b 42.
Further, the water outlet 43 includes a plurality of water outlet holes a431 distributed along the radial array of the mixing chamber 331.
Further, as shown in fig. 11, the limiting assembly 44 includes a water baffle 441 slidably disposed along a radial direction of the mixing bin 331, water outlets b442 disposed along a longitudinal direction of the water baffle 441 and aligned with the water outlets a431, and a limiting block 443 extending along a rotation direction of the mixing bin 331 and abutting against the water baffle 441; the limiting block 443 is fixedly arranged, and the initial end of the limiting block along the rotation direction of the mixing bin 331 is correspondingly arranged with the water inlet pipe b 42.
It should be noted that, when the water inlet tank 3312 is communicated with the water inlet pipe b42, the water baffle 441 moves to abut against the limiting block 443, so as to drive the water baffle 441 to move, and the water outlet hole a431 and the water outlet hole b442 are aligned, and the bottom of the mixing bin 331 is opened.
It should be further noted that, as shown in fig. 6 and 11, with the upward movement of the storage bin 31 and the rotating bin 33, the opening of the water inlet pipe b42 is upward, so that the sewage can be driven to carry the sewage in the mixing bin 331, and the flocculant in the mixing bin 331 is completely discharged during the period when the water inlet tank 3312 is communicated with the water inlet pipe b 42.
It is important to note that, as the rotating bin 33 is continuously rotated and moved upwards, the flocculant is uniformly spread at the respective heights of the sewage in the treatment tank 1, and the bottom of the rotating bin 33 is still required to be moved upwards and rotated for a plurality of circles after leaving the sewage level, so that the sewage in the mixing bin 331 is completely discharged.
It is worth mentioning that the equipment needs to be cleaned and maintained at intervals because the equipment needs to be immersed in sewage when in use, so as to maintain the optimal powdering effect.
Further, as shown in fig. 4, the air outlet assembly 52 includes a plurality of groups of hollow tubes 521 disposed below the rotating bin 33 and fixed at the bottom of the pipeline 51, a plurality of groups of air holes a522 disposed on the hollow tubes 521 and horizontally disposed in the axial direction, a moving tube 523 slidably disposed in the hollow tubes 521, an air hole b524 disposed on the moving tube 523 and alignable with the air holes a522, and a plug 525 disposed at the bottom of the pipeline 51 and capable of abutting against the moving tube 523.
As shown in fig. 11 and 12, when the rotating bin 33 moves downward, the air hole a522 is aligned with the air hole b524, and the plug 525 is communicated with the moving pipe 523 and the pipe 51, so that gas can be continuously introduced into the sewage; when the rotating bin 33 moves down to the position where the plug 525 abuts against the bottom of the tank body 1, the plug 525 moves up to drive the moving pipe 523 to move, so that the air hole a522 and the air hole b524 are dislocated, and the air outlet assembly 52 cannot charge air into sewage.
As shown in fig. 11 and 12, the rotating bin 33 does not rotate when moving downward, the air outlet assembly 52 performs air floatation operation, the pipe 51 and the air outlet assembly 52 rotate, and the hollow pipe 521 dials sewage to make oil dirt and impurities attached to the bottom of the rotating bin 33 float up fully; the rotation bin 33 rotates and discharges when moving upwards, at this time, the pipe 51 and the air outlet assembly 52 do not rotate, and the water outlet hole a531 can effectively prevent blocking when passing through the hollow pipe 521.
Further, as shown in fig. 13 and 14, the cleaning assembly 53 includes a mounting frame 531 disposed around the shroud 45, a filter screen a532 disposed around the mounting frame 531 at intervals, a rotating frame 533 disposed under the mounting frame a531, a filter screen b534 disposed on the rotating frame 533 at intervals and alignable with the filter screen a532, a guide groove 535 formed on the rotating frame 533, and a wedge 536 fixedly mounted on the bottom of the treatment tank 1 and aligned with the guide groove 535.
When the power assembly 34 drives the storage bin 31 and the rotating bin 33 to move downwards, the filter screen a532 and the filter screen b534 are in a superposed state, the air channel 51 ventilates to the lower side of the rotating bin 33, when the rotating bin 33 and the storage bin 31 move to the bottom, the wedge 536 contacts with the guide groove 535, the rotating frame 533 rotates, the filter screen a532 and the filter screen b534 are dislocated, and then when the power assembly 34 carries the storage bin 31 and the rotating bin 33 to move upwards, the filter screen a532 and the filter screen b534 can scrape floating foam generated by air floatation.
