Embodiment Construction

[0024] see figure 1 As shown, a Y-shaped water filter device in the prior art includes a water inlet pipe 1' at one end, a water inlet valve 2' for controlling the water inlet pipe 1', an outlet pipe 3' at the other end, a control The water outlet valve 4' of the water outlet pipe 3', the filter body 5', the cover plate 6' at the bottom of the filter body 5' and the filter element 7' inside the filter body 5'. Generally, the Y-shaped water filter device will be blocked after use. The usual method is to close the outlet valve 4' and the water inlet valve 2' of the Y-shaped water filter device, and close the cover plate 6' at the bottom of the Y-shaped water filter device. Open it, then remove the inner filter element 7' and wash it, then put the filter element 7' back into the filter body 5' after washing, and cover the cover plate 6', after completion, open the water inlet valve 2' and the water outlet valve 4'. However, this method of flushing the filter element is cumberso...

Abstract

The invention relates to a water filter apparatus, comprising a water inlet pipe disposed at one end of the water filter apparatus, a water inlet valve for controlling water inlet of the water inlet pipe, a water outlet pipe disposed at the other end of the water filter apparatus, a water outlet valve for controlling water outlet of the water outlet pipe, a filter body disposed between the water inlet pipe and the water outlet pipe, and a filter core disposed in the filter body. The water filter apparatus also comprises a back-washing apparatus which comprises a water draining pipe installed between the water inlet valve and the filter body and a water draining valve for controlling circulation of the water draining pipe. By installing a section of the by-pass water draining pipe and the water draining valve, the filter core in the water filter apparatus can be washed clean directly by using pressure in the pipe. Complex movements such as closing a series of valves, unloading a bottom cover plate, taking out the filter core, washing the filter core, installing the filter core and the like which are needed in an original method for washing the filter core are changed into a simple operation movement of opening and closing the valve, thereby saving labor and time.

Description

technical field [0001] The invention relates to a filter, in particular to a water filter device. Background technique [0002] The filter is a device to remove a small amount of solid particles in the liquid, which can protect the normal operation of the equipment. When the fluid enters the filter cartridge with a filter screen of a certain specification, the impurities are blocked, and the clean filtrate is discharged from the filter outlet. , when flushing is required, just take out the detachable filter cartridge and reinstall it after treatment, so the use and maintenance are extremely convenient. The main principle of the filter is to use the pore size of the filter medium to intercept substances larger than the pore size of the medium. Of course, some filter media also have special effects such as adsorption. [0003] The types of filters are divided into self-cleaning filters, fully automatic filters, and stainless steel brush filters according to their working prin...
