In addition, in the invention, a plurality of support rods 10 are arranged between the two clamping plates 6, and two ends of each support rod 10 are respectively connected with the two clamping plates 6 to play a role of auxiliary support; a plurality of lifting lugs 23 are arranged on the outer surface of the seal head 3, and a ring groove 5 for mounting the clamping plate 6 is formed between the bottom end of the seal head 3 and the top end of the barrel 9 in a matching manner; the motor 1 drives the sewage suction pipe 19 to rotate through the speed reducer 2; the bottom end of the water inlet cone 16 is connected with a water inlet pipe 13, a water outlet 14 is arranged on the water inlet pipe 13, and redundant sewage is discharged when the filter is stopped through the water outlet 14; a plurality of supporting legs 15 are arranged on the water inlet cone 16 and the water inlet pipe 13 in a matching way to support the filter.
The above is the common structure of the existing automatic backwashing filter, after sewage flows in through the water inlet cone 16, the sewage passes through the filter cylinder water through hole 24 on the lower clamping plate 6 and flows into the filter cylinder 18, and passes through the filter cylinder water through hole 24 on the upper clamping plate 6 and flows into the end enclosure 3, at this time, sewage is continuously added into the filter cylinder 18, the sewage passes through the side wall of the filter cylinder 18 and then flows out through the water outlet 20, namely, the sewage is filtered into clean water and flows out from the water outlet 20, and the sewage is filtered on the inner wall of the filter cylinder 18. Along with the continuous progress of filtration process, the filth on straining a 18 inner walls of section of thick bamboo can increase gradually, and the pressure in barrel 9 also increases gradually, detects the pressure in barrel 9 and rises to a definite value when differential pressure transmitter 8, opens blow off pipe 17 and makes motor 1 start. Because the pressure inside the cylinder 9 is higher, under the action of the pressure, the water in the cylinder 9 sequentially flows into the suction nozzles 21 and the sewage suction pipe 19 and is finally sent out through the sewage discharge pipe 17, the suction nozzles 21 are driven by the motor 1 to rotate along with the sewage suction pipe 19, the suction nozzles 21 continuously rotate on the inner wall of the filter cylinder 18, so that the dirt on the inner wall of the filter cylinder 18 is simultaneously sucked away while the suction nozzles 21 suck water, and the effect of automatically backwashing the filter cylinder 18 is achieved. Along with the back washing, the pressure in the cylinder 9 is gradually reduced, when the pressure difference transmitter 8 detects that the pressure in the cylinder 9 is reduced to a certain value, the blow-off pipe 17 is closed and the motor 1 is stopped, the back washing process is finished, and the automatic back washing filter can automatically continue to filter.
Since the above-mentioned conventional automatic backwashing filter must suck the filth on the inner wall of the filter cartridge 18 by means of the rotation of the suction nozzle 21 along with the filth suction pipe 19, the screen area is therefore limited by the size of the filter cartridge 18, resulting in a smaller filter area relative to the overall filter volume, the sewage treatment capacity is insufficient, therefore, a plurality of filter elements 7 are clamped between the two clamping plates 6 in a matching way, the plurality of filter elements 7 are all positioned at the outer side of the filter cylinder 18, and are arranged in two circles which are evenly arranged around the axis of the filter cylinder 18 at intervals, two circles of filter element water through holes 25 which are correspondingly connected with the end part of the filter element 7 are respectively arranged on the two clamping plates 6, when filtering is performed, the sewage flows into not only the filter cartridge 18 but also the plurality of filter elements 7 through the filter element water through holes 25, and under the condition that the whole volume of the cylinder 9 is not changed, the total area of the filter screen capable of filtering is increased, and the overall sewage treatment capacity of the filter is improved.
In order to enable the two circles of filter elements 7 to be capable of performing backwashing, the two hollow rotating arms 4 are additionally arranged in the barrel 9, the hollow rotating arms 4 are of hollow strip structures, the top end of the sewage suction pipe 19 is connected with the motor 1 through one hollow rotating arm 4, the bottom end of the sewage suction pipe 19 is communicated with the sewage discharge pipe 17 through the other hollow rotating arm 4, one side of the hollow rotating arm 4, which faces the clamping plate 6, is connected with two transition pipes 11, the transition pipes 11 and the hollow rotating arms 4 are integrally formed, and the two transition pipes 11 respectively correspond to the respective circles of filter element water passing holes 25.
When the motor 1 is started for backwashing, the hollow rotating arm 4 rotates along with the sewage suction pipe 19, so that the transition pipe 11 can sequentially pass through the end parts of the filter element water through holes 25 of the same circle when rotating along with the hollow rotating arm 4, namely, the four transition pipes 11 on the two hollow rotating arms 4 respectively correspondingly rotate on the end parts of the filter element water through holes 25 of the four circles on the two clamping plates 6, because the inner cavity of the hollow rotating arm 4 is communicated with the sewage suction pipe 19, the pressure in the hollow rotating arm 4 and the transition pipe 11 is also smaller than the pressure in the filter element 7 when backwashing is carried out, the sewage in the filter element 7 flows into the hollow rotating arm 4 under the pressure action, namely, in the rotating process of the hollow rotating arm 4, the transition pipe 11 sequentially aligns with the filter element water through holes 25 of the same circle when rotating, the sewage in the filter element 7 of the same circle sequentially flows into the hollow rotating arm 4 from the filter element water through holes 25, in addition, in the flowing process of sewage, the sewage in the filter element 7 can be taken away, so that the sewage filtered in the same circle of filter elements 7 is sequentially sucked out to the inner cavity of the hollow rotary arm 4 and is sent out through the sewage suction pipe 19 and the sewage discharge pipe 17, the automatic backwashing effect on the filter elements 7 is achieved, the defect that the backwashing process needs to depend on the suction nozzle 21 for direct adsorption is avoided, the defect that only one filter cylinder 18 can be arranged in the automatic backwashing filter is also avoided, and the effects that a plurality of filter elements 7 are additionally arranged in the automatic backwashing filter and the filtering area is increased are achieved. In order to ensure the effect that the transition pipe 11 and the filter element water through hole 25 are aligned with each other and absorb dirt, an elastic sleeve 12 is sleeved on the outer wall of the transition pipe 11, and the end part of the transition pipe 11 is tightly attached to the end surface of the clamping plate 6 through the elastic sleeve 12; in addition, a spring 22 is also arranged between the sewage suction pipe 19 and the suction nozzle 21, the suction nozzle 21 is tightly attached to the inner wall of the filter cylinder 18 through the spring 22, the suction effect on the sewage in the back washing process can be improved through the measures, the back washing process is accelerated, and the water treatment amount and the treatment effect are increased.
