The specific embodiment
Describe specific embodiment of the utility model in detail below in conjunction with accompanying drawing.Should be noted that the embodiments described herein only is used to illustrate, be not limited to the utility model.
As Fig. 2-shown in Figure 13, adjustable strainer head of the present utility model comprises built-in fitting 21, filter bar 23, upward filtration cap 22, filters cap 24 and securing member 25 down.
Built-in fitting 21 is embedded in the filter plate of BAF in advance.Built-in fitting 21 has central through hole, is provided with internal thread 212 on the top of central through hole wall, and the bottom is provided with internal thread 211.
The top of filter bar 23 is provided with installs groove 234, and the bottom is provided with draw-in groove 235.The bottom of filter bar 23 sidewalls is provided with the strip air distribution hole 232 that communicates with its internal cavity, at interval two circular air admission holes 233 is set on filter bar 23 sidewalls above the air distribution hole 232, and strip air distribution hole 232 is used for distribution, also can regulate the hydraulic pressure in the filter bar 23.Two air admission holes 233 and air distribution hole 232 can be arranged on the center line.
Securing member 25 is provided with the internal thread 251 that matches with the external screw thread 231 of filtering bar 23, securing member 25 with the filter bar 23 by being threaded togather of matching, the effect of securing member 25 is: strengthened the bonding strength between filter bar 23 and the built-in fitting 21, reduced the probability that filter bar 23 is washed out or damages.Certainly, in the utility model, also can use existing other fastening structures to realize being fastenedly connected between filter bar 23 and the built-in fitting 21.
Upward filtration cap 22 is truncated cone, evenly is furnished with some the filter seams 221 that are used for water outlet on its conical walls.The mask at the vertex of a cone circle place of truncated cone upward filtration cap 22 has the depressed part 222 that concaves, the existence of this depressed part 222 makes that the water that comes out through upward filtration cap 22 is more even, avoid the slough, help improving the effluent treatment and filtering effect, strengthened simultaneously the bearing capacity of upward filtration cap 22 greatly, the life cycle that has prolonged strainer head.
The conical walls of truncated cone upward filtration cap 22 stretches out along axis direction wherein and forms connecting portion 223, and this connecting portion 223 is provided with the external screw thread 224 that matches with internal thread 211 on the built-in fitting 21.Upward filtration cap 22 is connected on the built-in fitting 21 by threaded engagement.
Under filter cap 24 and be truncated cone, on its conical walls, evenly be furnished with some filter seams 241.The truncated cone mask at the vertex of a cone circle place of filter cap 24 down has the depressed part 242 that concaves, the existence of this depressed part 242 can make the water in the filter tank enter more equably in the filter bar 23 from all directions, main is to prevent that the suspension in the sewage from stopping up filter cap 24 down, helps improving the effluent treatment and filtering effect; Strengthened simultaneously the bearing capacity of time filter cap 24 greatly, the life cycle that has prolonged strainer head.
Under filter in the cap 24 and be provided with boss, this boss is used for cooperating with the draw-in groove 235 of filter bar 23 bottoms, is installed in and filters on the bar 23 thereby will filter cap 24 down, this syndeton is same as the prior art, repeats no more.
In actual engineering, the built-in fitting 21 in the adjustable strainer head of the utility model is together integrated poured with filter plate.When adjustable strainer head is installed, manually above filter plate, operate, filter bar 23 is entered by the top of built-in fitting 21, utilize special spanner to cooperate two installation grooves 234 on filter bar 23 tops to turn filter bar 23, by being threaded filter bar 23 and built-in fitting 21 are coupled together, can regulate be threaded with built-in fitting 21 partly length of filter bar 23 as required, to guarantee that each the following filter cap 24 that is installed in each filter bar 23 bottoms is maintained at the same horizontal plane, this work can be operated before filtrate is installed, therefore operate fairly simplely, save trouble; Upward filtration cap 22 is installed to the upper end of filter bar 23 by threaded engagement; Enter the water and air distributing chamber then and by threaded engagement securing member 25 is installed on the filter bar 23, and tightly be resisted against the bottom of built-in fitting 21, securing member 25 can be quincunx, and is convenient manual fastening, also can utilize special spanner fastening, and operation is very easy; At last, will filter the bottom that cap 24 is installed to filter bar 23 down by draw-in groove and boss cooperation.Can carry out water and air distributing according to arts demand and evenly debug, before filtrate is installed, both can the filter media room above filter plate install or debug adjustable strainer head, also can install or regulate filter in the water and air distributing chamber below filter plate.When filtrate installed finish after, water and air distributing chamber that can be below filter plate is installed and is regulated filter bar 23, also can debug by the length of regulating connecting thread.In the running of filter tank,,, very convenient as long as the emptying filter tank can enter the water and air distributing chamber and change or regulate if the filter bar damages or distribution when inhomogeneous.
The adjustable strainer head course of work of the present utility model is: sewage by under filter cap 24 enter the filter bar 23, suspension in the sewage is isolated in down outside the filter cap 24 at this moment, can not enter in the filter bar 23, sewage is flowed out by upward filtration cap 22 through filter bar 23, enters filter media room and carries out purified treatment.In sewage flow process from bottom to top, carry out distribution by two air admission holes 233, when air admission hole 233 stops up or his time spent is arranged, also can carry out distribution by strip air distribution hole 232.
Adjustable strainer head of the present utility model had both kept the advantage of traditional adjustable strainer head, and was even etc. as distribute water and air, can change or regulate filter under the filtrate situation needn't digging out again, very convenient, quick, greatly improved the operating efficiency in filter tank.
Though described the utility model with reference to several exemplary embodiments, should be appreciated that used term is explanation and exemplary and nonrestrictive term.The spirit or the essence that do not break away from utility model because the utility model can specifically be implemented in a variety of forms, so be to be understood that, the foregoing description is not limited to any aforesaid details, and should be in the spirit and scope that claim limited of enclosing explain widely, therefore fall into whole variations in claim or its equivalent scope and remodeling and all should be the claim of enclosing and contain.
