Description

A kind of filter and filtering device thereof

technical field

The utility model relates to the technical field of filtering equipment, in particular to a filtering device. In addition, the utility model also relates to a filter comprising the above filter device.

Background technique

When the filter is in the filtering state, tap water enters the filter from the water inlet, passes through the filter screen and then flows out from the water outlet. Particulate impurities, such as silt, rust, red worms, etc., will be intercepted by the filter screen and adhere to the surface of the filter screen or deposit at the bottom of the transparent cylinder, so as to achieve the filtering effect. In the flushing state, the drain ball valve at the bottom of the filter is opened, and the tap water flows to wash the filter screen surface, and the dirt adhered to the filter screen surface and deposited in the transparent cylinder is discharged from the drain ball valve.

Please refer to FIG. 1 and FIG. 2 . FIG. 1 is a schematic diagram of the working principle of a typical filter state in the prior art; FIG. 2 is a schematic diagram of the working principle of the flushing state.

The pre-filter is the first coarse filtration device for the whole house water, which can filter the sediment, rust and large particles in the tap water. It is usually installed behind the water meter of the water inlet pipe to ensure that a large amount of precipitated impurities generated in the pipe network will not cause harm to the human body, and it also plays a positive role in protecting the concealed pipes, faucets, electrical appliances, etc. The pre-filter is the nemesis of secondary pollution and a reliable impurity filtering device. The general pre-filter structure is shown in the figure below, which consists of a large copper body 1, a filter screen 2, a transparent cylinder 3, a drainage ball valve 4, and a sewage outlet 5.

The current pre-filter installation requires the transparent cylinder 3 and the drain ball valve 4 to be vertically downward, because the inclination angle of the filter is too large, which will cause the air inside the transparent cylinder 3 to be unable to discharge when the filter is filtering, which will affect the filter Filtration effect: the dirt intercepted by the filter screen 2 is easy to deposit and adhere to other parts or parts of the transparent cylinder 3, and the dirt cannot be deposited on the bottom of the transparent cylinder 3, which may easily cause unclean washing. And, the flushing mode of general pre-filter only relies on water flow to flush the filter screen surface, for the dirt adhering to the filter screen 2, the effect is not good, it is difficult to rinse off.

To sum up, how to effectively solve the problem that the filter is not easy to rinse clean is an urgent problem for those skilled in the art.

In a specific embodiment, the filter device provided by the present invention is installed in the cylinder body 3 of the filter, and includes a central rod 5, a filter screen and a blowdown valve, and the blowdown valve can specifically be a blowdown ball valve. The central rod 5 is installed at the center of the cylinder body 3, and the central rod 5 can rotate 3360 degrees around the cylinder body, and the central rod 5 can rotate 360 degrees, which can realize the complete flushing of the filter screen. The filter screen is set outside the central rod 5 for filtering water. There are gaps between the filter screen and the central rod 5 and between the filter screen and the cylinder 3. The tap water enters the filter device in the cylinder 3 of the filter from the water inlet. Filter, become pure water through the filter screen, the pure water enters the cylinder 3, and the purified water is discharged from the water outlet after passing through the cylinder 3. There is a sewage suction port 51 on the side wall of the central rod 5, and there is a cavity inside the central rod 5. The cavity communicates with the sewage suction port 51. A sewage valve is installed at the bottom of the cavity. Turn the sewage discharge knob 2 to open the sewage valve. , the cavity inside the central rod 5 is directly connected to the sewage valve, and the sewage suction port 51 of the central rod 5 will have a large adsorption force under the action of water pressure, and the rotation of the central rod 5 can suck the dirt on the filter net into the sewage suction port 51, Then the dirt enters the cavity, the cavity is connected to the sewage valve, and the sewage valve can discharge the dirt from the sewage outlet.

In the filter device provided by the utility model, the cylinder body 3 and the blowdown valve do not need to be vertically downward, and the angle of inclination is not limited.
