A hose suction nozzle of a filter includes a hose and a nipple; the hose is a bendable flexible plastic pipe; the joint is a pneumatic joint; the hose is inserted into the joint; the fitting is used to secure the hose in position during use. The utility model relates to a filter's hose suction nozzle can press close to the filter screen, produces the friction with great filter residue on the filter screen for great filter residue diminishes and is siphoned away by the suction nozzle, can effectively siphoning away the filtration thing that attaches on the filter screen more, the effectual dirty effect of having improved the suction. The utility model has the characteristics of simple structure, easily installation or change.

Description

Hose suction nozzle of filter

Technical Field

The utility model relates to a self-cleaning net formula field of filtering, more specifically say, relate to a hose suction nozzle of water conservancy drive filter.

Background

At present, a back washing mechanism is generally used for cleaning a filter screen in the field of water conservancy driving filters. When a control system sends a cleaning and sewage discharging signal, a sewage discharging valve is opened, the system releases pressure and discharges water, a suction force is generated at a suction nozzle to suck impurities into a sewage discharging shaft to discharge, sewage generates axial thrust through a water conservancy motor, the sewage discharging shaft rotates and moves radially at the same time, and the suction nozzle rotates and displaces on the inner surface of a filter screen to clean the impurities in the filter screen.

A large part of suction nozzles of suction filters used at present are directly molded by injection molding grinding tools and can be used after being assembled, but the gap between the suction nozzle and a filter screen cannot be accurately controlled. The distance between the suction nozzle and the filter screen is too large, so that the suction force reaching the filter screen is small, and the filter screen is not beneficial to cleaning; if the distance between the suction nozzle and the filter screen is too small, the suction nozzle may rub against larger filter residues on the filter screen and be stuck.

Disclosure of Invention

An object of the utility model is to provide a hose suction nozzle of filter, the solution adsorbs the suction nozzle of filter residue in the filter screen cleaning process because the too far suction of distance filter screen is not enough and because the too near card of distance filter screen is at these two problems on the net, improves the cleaning efficiency of filter screen.

The purpose of the utility model can be realized through the following technical scheme:

a hose nozzle of a filter comprises a hose and a joint; the hose is a bendable flexible plastic pipe; the joint is a pneumatic joint; the hose is inserted into the joint; the fitting is used to secure the hose in position during use.

The utility model has the advantages as follows:

firstly, after the hose suction nozzle of the filter is used, the suction nozzle is closer to the net surface for adsorbing filter residues, and the suction of the filter residues is more ideal; secondly, due to the flexible characteristic of the hose, under the condition that large filter residues exist, the hose cannot be clamped after being directly rubbed with the large filter residues, and the large filter residues are sucked away after being ground for multiple times of rubbing, so that the effect of cleaning the filter screen is achieved. Thirdly, the utility model has the advantages of simple integral structure and easy installation or replacement.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

A hose nipple for a filter as shown in fig. 1 or 2, comprising a hose 1 and a nipple 2; the hose 1 is a flexible plastic tube; the joint 2 is a pneumatic joint; the hose 1 is inserted into the joint 2; the fitting 2 is used to fix the position of the hose 1 in use.

Preferably, the hose 1 is proximate to the sieve 4;

preferably, the hose 1 is fixed on the rotating shaft 3 through the joint 2;

preferably, the shaft 3 is a hollow cylinder which can rotate, and filter residue sucked in through the hose 1 can be discharged outwards through the shaft 3.

By comprehensive and integral application, the hose suction nozzle of the filter shown in fig. 1 or 2 is simple and easy to install, use or replace, the material of the hose 1 is convenient to obtain, and the application cost is reduced.

The utility model discloses a concrete example is applied to explain the principle and the implementation mode of the utility model, and the explanation of the above example is only used to help understand the method and the core idea of the utility model; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the concrete implementation and the application scope. In summary, the content of the present specification should not be construed as a limitation of the present invention.

Claims (1)
