Description

The device of floatation reflux water filtering
Technical field
The present invention relates to filter device fields, and in particular to the device of floatation reflux water filtering.
Background technique
Air floatation machine mainly includes air dissolving system and pond body, and pond body includes reaction zone, contact mixed zone, Disengagement zone and filtering Area, sewage initially enter reaction zone, carry out flocculation reaction;Then by water distributor enter contact mixed zone, and herein with it is molten Gas system provides dissolved air water mixing, and microbubble is enabled effectively to be adhered to floc particle surface, forms gross density and is less than water Particle;Enter Disengagement zone using partition, and carry out FLOTATION SEPARATION herein, tentatively completion separation of solid and liquid process;Most pass through afterwards Cross filtering area filtration treatment.Wherein, air dissolving system includes dissolving and reflux water pump, and reflux water pump will be filtered by return line The water outlet in area, which is delivered in dissolving, is processed, and since the water outlet of filtering area also contains impurity, can block reflux water pump, therefore Filter is installed to the further filtration treatment of water outlet on return line.And filter mostly uses Y-filter, Y-filter peace On return line outside loaded on pond body, main includes supervisor, branch pipe and filter cylinder, and one end of supervisor is sewage upstream end, the other end For water purification outlet end, branch pipe is connected to supervisor in an inclined manner, is inserted in branch pipe, is fixed with filter cylinder, the end sections of filter cylinder It stretches to the connection position of supervisor and branch pipe and passes through, need equipment downtime to let out to avoid sewage from branch pipe when cleaning filter cylinder Leakage, and then influence daf efficiency.
Summary of the invention
The present invention provides the devices of floatation reflux water filtering, can solve the filter on existing floatation reflux pipeline The technical issues of cleaning need to shut down equipment, influence daf efficiency.
Its technical solution be it is such, the device of floatation reflux water filtering, pneumatically supported pond body is connected with and return line The outlet pipe of connection, the reflux Water filtration structure include the first filter cylinder, and the side wall of first filter cylinder offers filter opening, special Sign is: the reflux Water filtration structure further includes pilot unit, fixed plate and traction unit, and the outlet pipe extends to described Vertical support tube body is bent to form after pond body upwards, the support tube body is connected with fixed plate, the upper end of first filter cylinder Opening is connected with cover board, lower ending opening is supported in the fixed plate and is connected to the support tube body, first filter cylinder It connects traction unit and is oriented to pilot unit and cooperated, the pilot unit is vertically extending, and first filter cylinder can be The pond body is pulled out along the pilot unit under the action of traction unit, first filter cylinder can be settled along the pilot unit It is connected on to the fixed plate and with the support tube body.
Further, the reflux Water filtration structure further includes the second filter cylinder, and first filter cylinder is sheathed on described second Outside filter cylinder, the upper end opening of second filter cylinder is connected with cover board, lower ending opening is supported in the fixed plate and with it is described Tube body connection is supported, the traction unit stretches out the pond body after running through second filter cylinder.
Further, second filter cylinder is fixedly connected with the fixed plate, and the side wall of first filter cylinder offers Filter opening, the pilot unit are guide rod, and the lower end of the guide rod is fixedly connected with second filter cylinder, upper end is through described It is upwardly extended after first filter cylinder, the traction unit is drawstring, and the drawstring stretches out the pond body after running through second filter cylinder.
Further, the cover board of first filter cylinder and second filter cylinder offers filter opening.
Further, second filter cylinder is removably secured with the fixed plate connect.
When first filter cylinder of the invention needs to clean, the first filter cylinder is pulled out along pilot unit under the action of traction unit Then the first filter cylinder after cleaning or after replacement is settled down to fixation along pilot unit to carry out Rapid Cleaning or replacement by pond body Be connected on plate and with support tube body, the first filter cylinder clean or replacement process in it is anhydrous will not leak, airfloat equipment is without stopping Machine, it is ensured that daf efficiency;Meanwhile second filter cylinder setting, can the first filter cylinder clean or replacement process still ensure that Effect filtering.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
As shown in Figure 1, the device of floatation reflux water filtering, pneumatically supported pond body 7 is connected with going out of being connected to return line Water pipe 1, reflux Water filtration structure include the first filter cylinder 4, pilot unit 6, fixed plate 2 and traction unit 5, the side of the first filter cylinder 4 Wall offers filter opening, and outlet pipe 1 extends to after pond body and is bent to form vertical support tube body 1b upwards, and support tube body is connected with solid Fixed board 2, the upper end opening of the first filter cylinder 4 is connected with cover board, lower ending opening is supported in fixed plate 2 and connects with support tube body 1b Logical, the first filter cylinder 4, which connects traction unit 5 and is oriented to pilot unit 6, to be cooperated, and pilot unit 6 is vertically extending, the first filter cylinder 4 can pull out pond body along pilot unit 6 under the action of traction unit 5, and the first filter cylinder 4 can be settled down to solid along pilot unit 6 It is connected on fixed board 2 and with support tube body.
The Water filtration structure that flows back further includes the second filter cylinder 3, and the first filter cylinder 4 is sheathed on outside the second filter cylinder 3, the second filter cylinder 3 Upper end opening is connected with cover board, lower ending opening is supported in fixed plate 2 and be connected to support tube body, and traction unit 5 runs through the Pond body is stretched out after two filter cylinders 3.The setting of second filter cylinder can clean in the first filter cylinder or replacement process still ensures that effectively mistake Filter.
