Water treatment equipment

Abstract

The invention provides a water treatment device, comprising column filter unit groups and a control device for controlling the water flow distribution. Wherein, each column filter unit group comprises two column filter units; said control device comprise the front control valve and a back control valve, while the control valve comprises a valve casing and a valve core; the valve core is arranged inside the valve casing; the valve casing of each control valve has two opposite water inlet-outlet holes connected to the upper and lower channels of column filter; the casing of upper valve has a main water inlet while the lower valve has a main water outlet; the lower bottom cover of upper valve has a soil exhaust hole while the lower bottom cover of lower valve has a reverse washing hole; a water chamber connected to the main water inlet is mounted inside the upper valve casing of upper valve core; and the a water chamber connected to the main water outlet is mounted inside the upper valve casing of lower valve core. The inventive water treatment device can be operated in the conditions of feeding water, reverse washing and positive washing, while it can feed water when in reverse or positive washing to improve the water feeding efficiency. And since the invention has the added positive washing process, the water feeding quality is improved.

Description

technical field

[0001] The invention relates to a water treatment device. Background technique

[0002] Existing column-type water treatment equipment, such as mechanical filters, deaerators, etc., have working states such as water production and backwashing during the working process, and the conversion between the states is completed by the control valve. Patent No. 00215874.4 is a utility model patent. The water treatment equipment described in its published specification has working states such as water production and backwashing in a working cycle, but water production and backwashing cannot be performed at the same time. In the working state of backwashing, water cannot be produced, and in the working state of water production, backwashing cannot be performed, which greatly reduces the efficiency of water production, and there is no positive washing process, so even after backwashing, the quality of produced water is not very good High, the water quality is relatively...
