Description
Technical field
The present invention relates to a kind of rotary self-cleaning filter of calibration that farm irrigation system is filtered.
Background technology
The current self-cleaning filter that is used for the land for growing field crops irrigation system generally all is to utilize the clear water of a part of strainer filtering to come another part filter screen is carried out backwash; Do not accomplish the disposable super backflush of whole filter screen is washed, the unavoidable like this part filter screen that makes can not obtain sufficient backwash, causes some impurity to rest on the filter screen place; Long-term accumulated; Can cause certain damage to filter screen, reduce the service life of filter screen, increase the cost of system's operation.The disclosed a kind of differential full-automatic drain filter of Chinese patent CN2737448Y, it is by a columniform housing and set up on it water inlet, delivery port and sewage draining exit to constitute simultaneously, is provided with screen pack in the described housing; Said water inlet and delivery port are respectively equipped with intake pressure and measure mouth and discharge pressure mensuration mouth, are linked by pressure controller between the two; Said sewage draining exit place and housing front end are respectively arranged with blowdown actuator and backwash actuator, and this blowdown actuator is connected with differential pressure controller respectively with the backwash actuator.Its weak point is that the filter screen between water inlet and the pressure-control valve is in the state of filter medium always; That is to say flinging of filter wash with two kinds of situation of backwash under, filter screen all is in the state of filtration here, if things go on like this impurity of some fibre type is relatively easy to adhere on the filter screen; Filter screen is here stopped up; Reduced the mistake water yield of this filter screen, thereby reduced clear water amount, reduced the backwash efficient of filter the backwash of rearmounted filter screen.In order to address the above problem, the present invention has been proposed.
Summary of the invention
The invention provides the rotary self-cleaning filter of a kind of calibration; Purpose is to solve fully backwash of part filter screen in the present self-cleaning filter; And be in the filtration state that flings for a long time; Thereby cause this part filter screen to be in the obstruction of impurity for a long time, reduce filter screen service life, increase the problem of operating cost.
The rotary self-cleaning filter of a kind of calibration comprises filter housings, and housing is provided with outer gland, water inlet, filter core, delivery port, sewage draining exit and controller; Housing is formed by two sections, is provided with stationary barrier in the housing, is provided with rotatable locking disk and gland above the stationary barrier successively; Gland and stationary barrier are for removably connecting, and stationary barrier inboard and housing bottom are provided with the matrix cushion rubber, and tubular center framework upper and lower side with holes stretches in the groove of matrix cushion rubber; Filter core is positioned at the center framework inboard and is closely contact; Filter core upper end is that flute profile is connected with a joggle with locking disk, and controller passes outer gland, the gland drive filter core that links to each other with locking disk and rotates, and is provided with the circular arc baffle plate between center framework outer wall and the inner walls; The two ends of circular arc baffle plate are provided with rubber septum; Rubber septum contacts with the center framework outer wall, and circular arc baffle plate upper and lower side is inserted in the matrix cushion rubber, and the rubber septum upper and lower side contacts with the matrix cushion rubber; Form the backwash cavity between circular arc baffle plate, rubber septum and the center framework, sewage draining exit extends internally and communicates with the backwash cavity.
The rotary self-cleaning filter of above-mentioned calibration, its circular arc baffle plate arc length account for the 1/4-1/3 of the total circle of center framework.Be convenient to calibration.
The rotary self-cleaning filter of above-mentioned calibration, the rubber septum of its circular arc baffle plate both sides becomes tangent layout with the center framework outer wall.Center framework resistance when rotated is littler, and what rubber septum and center framework pasted during backwash is tightr.
The rotary self-cleaning filter of above-mentioned calibration, its delivery port extends inwardly to concordant with the matrix cushion rubber, is convenient to the placement of matrix cushion rubber and fixing of position.
The rotary self-cleaning filter of above-mentioned calibration is provided with the ring-type partition between its filter core bottom and the matrix cushion rubber, and partition lower end bossing stretches in the matrix cushion rubber, the resistance in the time of can reducing the center framework rotation through increasing the ring-type partition.
The rotary self-cleaning filter of above-mentioned calibration, its housing two ends, outer gland are bolt with housing, gland with stationary barrier and are connected, for convenience detach and maintenance.
The present invention has set up curved baffle and rubber septum outside filter core, and then has formed the backwash chamber, through controller rotation filter core, successively filter core is carried out super backflush and washes.When filter core constantly filtered sewage, some impurity were stopped on the filter core, through the regular hour; Cause the inside and outside pressure differential of filter screen, under action of pressure, rubber septum and center framework outer surface are adjacent to; Form back washing area, make that filter screen and sewage that this is regional are isolated, temporarily stopped filtration sewage; Other part filter screen of rotary sieve keeps the sewage water filtration state, crosses the clear water that filters and will carry out backwash to this part filter screen conversely, opens the valve on the blow-off pipe; Addle after the filtration is discharged by blow-off pipe; Thereby accomplish the backwash of this regional filter screen, the driven rotary filter screen rotates to next back washing area under controller action, makes whole filtering net obtain backwash completely successively.Thereby solve fully backwash of part filter screen in the present self-cleaning filter, and be in the filtration state that flings for a long time, cause this part filter screen to be in the obstruction of impurity for a long time, reduce filter screen service life, increase the problem of operating cost.Secondly, housing of the present invention is that two sections compositions are convenient to dismounting and maintenance.The present invention can be widely used in the filtration of the preceding filtration of various pumps, industrial water supply, chemical industry system water and well water, river.
The present invention is simple in structure, and its advantage is following:
1, in filter housings, be provided with circular arc baffle plate and rubber septum, thoroughly accomplish backwash whole filtering net through controller driven rotary filter screen, need be by other filter element.
2, be in continuous state at filter process and backwash process always, need do not close any import and export.
3, this invention is easy and simple to handle, and filter efficiency is high, has effectively increased the service life of filter screen, reduces operating cost.
