Description

Horizontal floating ball liquid level switch control device

Technical Field

The utility model relates to the technical field of sewage treatment, in particular to a horizontal floating ball liquid level switch control device.

Background

In water supply and drainage operation, a float switch is commonly used as a device for controlling the start and stop of a water pump so as to control the liquid level of a water tank or a water pool. The float switch can change the closing of the contact inside the float according to the height of the water level, so as to achieve the purpose of controlling the start and stop of the water pump. When the water quality is clear water, the control device has no problem. However, when the water is sewage, the sensitivity of the traditional float switch is reduced because the water contains a large amount of impurities, garbage and some floaters, and even the traditional float switch is wound or pressed by the garbage and the floaters in the water, so that the traditional float switch cannot float normally, and the switch fails. The water pump controlled by the floating ball can not be started and stopped normally, so that the water discharge accident occurs.

In addition, the sewage treatment apparatus of a building is usually installed under the ground (the basement bottom layer of the building), the installation space is usually narrow, and the equipment is limited by the installation site space to be large. Therefore, on the premise of ensuring the sewage treatment capacity of the equipment, other auxiliary equipment needs to occupy smaller space as much as possible.
