Embodiment 1

[0033] like Figure 1-6 As shown, a pipeline filter device with self-cleaning function includes an outer wall 1 and a filter screen 2. The outer wall 1 is in the shape of a circular tube, and the two ends can be connected to structures such as pipes and faucets. The two ends of the outer wall 1 can also have other shapes. The net 2 is arranged on the middle front end inside the outer wall 1, and the left side of the filter screen 2 is provided with an annular concave platform 11 formed on the outer wall 1, and a water outlet 19 is provided on the right side, and the annular concave platform 11 is rotatably provided with The ball valve 3 is provided with a valve hole 31 at the center of the ball valve 3 for through-flow, and a ball valve hand wheel 4 is fixedly connected above the ball valve 3 .

[0034] In order to further improve the performance of the present invention, a recoil inlet pipe 32 is provided on the ball valve 3 and perpendicular to the axis of the valve hole 31,...

Embodiment 2

[0045] Compared with Embodiment 1, this embodiment is characterized in that a boss 61 is provided outside the sewage outlet 12, and a cap 6 is provided outside the boss 61, and the cap 6 is connected to the boss 61 through threads.

[0046] The use process and working principle:

[0047] First, connect corresponding structures on the outer walls 1 at both ends of the present invention, such as water pipes, faucets and other structures.

[0048] During normal use, firstly plug the sewage outlet 12 with the piston 5 or the cap 6, then install the filter, and then press the reset shaft 41 to rotate the hand wheel 4 of the ball valve. After a certain angle of rotation, it can be released and reset Press the shaft 41 to continue to rotate the ball valve handwheel 4. When the rotation does not stop, the staple 44 has been inserted into the valve opening groove 441 under the action of the first return spring 42. At this time, the ball valve 3 is in the open state, that is, the valve ...

Abstract

The invention discloses a pipeline filtering device with a self-cleaning function. An outer wall and a filter screen are included, the outer wall is in a circular tube shape, and the filter screen isarranged at the middle front end in the outer wall; an annular concave table formed on the outer wall is arranged on the left side of the filter screen; a water outlet is formed in the right side of the annular concave table, a ball valve is rotatably arranged in the annular concave table, a valve hole is formed in the center of the ball valve, a sewage draining exit is formed under the outer wallbetween the filter screen and the ball valve, a conical surface with a certain size is formed in the inner side of the sewage draining exit, and a ball valve hand wheel is fixedly connected to the upper portion of the ball valve; compared with the prior art, the pipeline filtering device has the following advantages that the filter screen can be self-cleaned; when the filter screen needs to be cleaned, the ball valve is closed firstly, backwash is conducted by pressing the arranged backwash button at the moment, and troublesome operation of manual cleaning of the filter screen is avoided; a sewage draining outlet is formed for draining sewage; the filter screen is easily replaced, the service life is prolonged, and the environment is improved; the stable and adjustable ball valve is provided.

Description

technical field [0001] The invention relates to the technical field of pipeline filtering, in particular to a pipeline filtering device with self-cleaning function. Background technique [0002] Pipeline filtration is widely used in municipal, household, industrial and many other industries, and is mainly used to filter impurities in pipelines to prevent troubles for subsequent use or blockage of equipment. Especially in mountainous and rural areas, most of the drinking water is from nearby mountain springs. In the absence of standardized treatment, there will inevitably be some large impurities in the water; in addition, long-term intermittent use of water pipes is also unavoidable. The algal plants that produce moss occasionally bring out some large impurities during use, so the water needs to be filtered. [0003] At present, there are some filters installed at the water outlet of the faucet, but all of them need to be disassembled and cleaned manually. When cleaning, th...
