Specific embodiment

In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain The utility model, is not used to limit the utility model.

Fig. 2~5 are referred to, wherein Fig. 2 is the overall structure diagram of the fore filter that the utility model is provided；Fig. 3 It is on the basis of Fig. 2, according to the cross section structure diagram of A-A hatchings；Fig. 4 is part B amplification in cross section structure diagram Figure；Fig. 5 is the firm banking structural representation that the utility model is provided.

The utility model example provides a kind of fore filter.The fore filter includes fore filter body 1, The fore filter body is in T-shape structure, and the T-shape transverse part is the copper lid 11 with medium entrance and media outlet, Vertical part is the cylinder 12 with sewage draining exit 121；It is arranged at the draining valve module 13 at the sewage draining exit 121, is arranged on the cylinder Filter screen skeleton 122 in body 12 and the first filter screen 123 being arranged on the filter screen skeleton 122 and net scrape 124, the first filter screen 123 are sandwiched in filter screen skeleton 122 and net is scraped between 124；The draining valve module 13 is ball valve, is set on the valve rod 131 of the ball valve There is drain knob 132；

Also include firm banking 2；

The firm banking 2 is set in the outer wall of draining valve module 13；The firm banking 2 is offered for by row It is fixed with the first through hole 211 of dirty pipe 14, the first through hole 211 curved for changing the water pipe of the pipeline rout of the blowdown 14 First 212；The firm banking 2 can be relatively rotated with the drain knob 132.

Preferably, the discharge and collection of the utility model fore filter sewage, the firm banking for convenience " L " type is designed to, in the outside wall surface of the fixed cover of vertical part 21 loaded on the draining valve module 13 of " L " type described in it, works as rotation When net scrapes 124, the drain knob 132 of draining valve module 13 is rotated, and firm banking 2 is maintained static；The transverse part 22 of " L " type The second through hole 221 is offered, second through hole 221 is used to realize the water pipe elbow 212 with the company of the blow-off pipe 14,15 Connect, so as to realize that vertical blow-off pipe 14 and horizontal blow-off pipe 15 turn to sewage effluent.

Preferably, the water pipe elbow 212 is 90 ° of elbows or 45 ° of elbows, by 90 ° or 45 ° of elbows, no Only realize the steering of sewage, but also be fore filter compact conformation, save fore filter take space.

Preferably, the transverse part 22 of described " L " type is provided with the mill line for improving frictional force, is provided with the position of mill line described On the surface that transverse part 22 is contacted with ground.

It is further preferred that transverse part 22 is a plate-like structure, by platy structure, ground is improved in face of fore filter Support strength.

Fore filter in the utility model above-described embodiment, fixation is increased in the sewage draining exit of fore filter body Base, can relatively rotate between firm banking and draining knob, realize blow-off pipe when rotation net scrapes blowdown and do not rotate and side Just the function of sewage is collected；While product function is increased, more convenient user uses.

Use process description of the present utility model is as follows：
