Abstract
The utility model discloses a suction nozzle of a suction filter, which consists of a collecting pipe, a suction nozzle and a suction nozzle sheath, wherein the collecting pipe is connected with a sewage draining outlet, and collected impurities are intensively discharged during backwashing; the suction nozzle is cylindrical and is vertically fixed on the collecting pipe, and a section of small-sized cylindrical step is arranged at the suction nozzle at the front end of the suction nozzle; the suction nozzle sheath is sleeved on the suction nozzle and is attached to the inner wall of the filter screen. The utility model discloses a suction nozzle protective sheath has increased the clearance between suction nozzle and the filter screen, when the backwash blowdown, can inhale more impurity to the backwash effect has been guaranteed.
Description
Technical Field
The utility model relates to a self-cleaning net formula field of filtering, more specifically say, relate to a suction nozzle of water conservancy drive filter.
Background
At present in water conservancy drive filter field mostly adopt water conservancy piston to promote to suck a section of thick bamboo and carry out the double entry washing, send the washing blowdown signal when control system, the blowdown valve is opened, and blowdown chamber pressure releases suddenly, produces suction and inhales impurity in suction blow off axle discharge in suction nozzle department, and sewage passes through water conservancy motor and produces axial thrust, and the blow off axle is rotatory this moment, is radial motion simultaneously, and rotary displacement is made at the filter screen internal surface to the suction nozzle, clears up inside impurity.
The suction nozzle of the current suction type filter is similar in main structure form, and is different in material, namely a stainless steel processing piece and an injection molding piece made of plastic. For the suction nozzle in the stainless steel form, firstly, the manufacturing process is complex, blanking, punching, assembly welding, metal processing and the like are needed, in addition, the coaxiality of the suction shaft and the clearance between the suction nozzle and an inner net are not well ensured, and when the suction nozzle rotates in a backwashing way, the clearance is too small, so that a filter screen is easily abraded; the clearance is too large, and the dirt suction capability is poor. To the suction nozzle of plastics material, the grinding apparatus direct forming of moulding plastics just can use after assembling, but the clearance control of suction nozzle and filter screen can't reach accurately, when the backwash rotates, or the backwash effect is not good, will cause the wearing and tearing of suction nozzle certainly.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides an inhale formula filter suction nozzle, simple structure, convenient to use, the backwash is effectual.
The utility model discloses a concrete technical scheme does: a suction nozzle of a suction filter consists of a collecting pipe, the suction nozzle and a suction nozzle sheath, wherein the collecting pipe is connected with a sewage draining outlet, and collected impurities are intensively discharged during backwashing; the suction nozzle is cylindrical and is vertically fixed on the collecting pipe, and a section of small-sized cylindrical step is arranged at the suction nozzle at the front end of the suction nozzle; the suction nozzle sheath is sleeved on the suction nozzle and is attached to the inner wall of the filter screen.
Furthermore, the suction nozzle sheath is made of soft rubber, the wall thicknesses of two ends of the suction nozzle sheath are different, the inner diameter of the thick end of the suction nozzle sheath is smaller than the outer diameter of the cylindrical step at the position of the suction nozzle, and the thin end of the suction nozzle sheath is attached to the inner wall of the filter screen.
Compared with the prior art, the utility model has the advantages that:
1) the suction nozzle of the suction type filter has simple structure, easy manufacture and convenient use;
2) the suction nozzle sheath is added in the utility model, the sheath is made of rubber, the filter screen cannot be abraded, the manufacturing requirement of the roundness of the filter screen is reduced, the sheath is used as a brush during backwashing, and the backwashing effect is good;
3) the utility model provides a suction nozzle sheath and suction nozzle are detachable, are convenient for change.
Drawings
FIG. 1 is a schematic view of a suction shaft assembly of the suction filter of the present invention;
FIG. 2 is a schematic view of a nozzle sheath of the suction filter of the present invention;
in the figure: 1-collecting pipe, 2-suction nozzle, 3-suction nozzle jacket and 4-filter screen.
Detailed Description
The invention is further described with reference to the drawings and examples.
As shown in figure 1, the suction type filter suction nozzle consists of a collecting pipe 1, a suction nozzle 2 and a suction nozzle sheath 3. The collecting pipe 1 is connected with a sewage draining outlet, and collected impurities are intensively drained during backwashing; the suction nozzle 2 is cylindrical and is vertically fixed on the collecting pipe 1, and a section of small-sized cylindrical step is arranged at the suction nozzle at the front end; the suction nozzle sheath 3 is sleeved on the suction nozzle to protect the suction nozzle from abrasion, and the suction nozzle sheath 3 is attached to the inner wall of the filter screen 4.
As shown in fig. 2, the nozzle protector 3 is made of a soft rubber material to prevent the filter screen from being scraped. Meanwhile, in order to enable the suction nozzle sheath 3 to be firmer, the wall thicknesses of two ends of the suction nozzle sheath 3 are different, the inner diameter of the thick end is smaller than the outer diameter of a cylinder at the position of the suction nozzle, the thick end can be sleeved on the suction nozzle 2 more firmly, the thin end is good in flexibility and is attached to the inner wall of the filter screen 4, and the suction nozzle sheath 3 is enabled to fill the gap between the suction nozzle and the filter screen 4.
When the backwashing is rotated, the suction nozzle jacket 3 can not influence the rotation of the collecting pipe 1, and can also play a certain brush role, so that the backwashing effect is better. When the backwashing effect is not obvious, the filter is disassembled, the suction shaft assembly is taken out, and the new suction nozzle sheath 3 is directly replaced to continue to be used, so that the cost is saved, and the device is convenient and fast.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
