Embodiment 1

[0027] pre-filters such as Figure 1-Figure 5 As shown, it includes a cylinder body 1, a filter element assembly 2 is arranged in the cylinder body 1, and a hollow rod 3 passing through the filter element assembly 2 is also arranged in the cylinder body 1, the bottom of the hollow rod 3 communicates with the interior of the cylinder body 1, and the top passes through The cylinder body 1 is also connected with an electric ball valve 4 , and the electric ball valve 4 is provided with a sewage outlet 41 . The inner diameter of the hollow rod is 1 cm.

[0028] In this embodiment, a control panel cover 8 is installed above the valve head seat 5 , wherein the electric ball valve 4 is fixed in the control panel cover 8 and the sewage outlet 41 extends out of the control panel cover 8 . The control panel cover 8 is provided with a control panel, and the control panel is provided with buttons for controlling the time setting module and the flushing module. By pressing the correspondin...

Embodiment 2

[0040] Same as embodiment 1, the difference is that in this embodiment, the pre-filter is flushed manually, and the forward flushing and backwashing of the pre-filter are controlled by manually controlling the electric ball valve 4 and the lifting mechanism 7, so that the pre-filter is closed In the case of the automatic flushing function, the manual flushing function is still valid, which effectively improves the operational flexibility. Meanwhile, the inner diameter of the hollow rod in this embodiment is 10 cm.

Abstract

The invention relates to the field of purification equipment, and discloses a pre-filter, which includes a cylinder body (1), a filter element assembly (2) is arranged in the cylinder body (1), and a through-filter element is also arranged in the cylinder body (1). The hollow rod (3) of the assembly (2), the bottom of the hollow rod (3) communicates with the inside of the cylinder (1), the top of the hollow rod (3) passes through the cylinder (1) and is connected to the electric ball valve (4), the electric ball valve (4) A sewage outlet (41) is provided. The invention achieves better forward flushing and backwashing effects by rationally designing the pre-filter, and realizes its flushing function through fully automatic control, and has the advantages of high efficiency, low cost, and strong adaptability.

Description

technical field [0001] The invention relates to the field of purification equipment, in particular to a pre-filter. Background technique [0002] At present, due to the old and long urban water supply pipelines, the production pipelines are corroded, the corrosion of pipelines, sediment and other impurities will not only cause brown water and control failures of water equipment, such as faucet dripping, heat exchanger pipeline blockage, rupture, and impurities will be in the pipeline. On the one hand, it provides a hotbed for the growth of bacteria, and on the other hand, it will form electrochemical substances, which can cause corrosion or perforation of metal pipes in just a few months. The tap water pre-filter is the first coarse filtration equipment for the whole house water, which can filter the sediment, rust and large particles in the tap water. It is a reliable impurity filtering device, which restores tap water to the standard before leaving the factory, protects d...
