Water discharge system for a filter

Abstract

The invention discloses a water discharge system for a filter. The water discharge system comprises a settling cup, wherein a water discharge control module and a water discharge electromagnetic valveare arranged at the bottom of the settling cup, and the water discharge control module is adjacent to the water discharge electromagnetic valve; the water discharge control module comprises a high water level probe and low water level probes for monitoring the water level in the settling cup, the high water level probe is arranged higher than the low water level probe, and the high water level probe is arranged at preset starting water discharge level and the low water level probes are arranged at preset ending water discharge level; and the high water level probe and the low water level probes are connected with an electric control device; a water discharge pipe for discharging water is arranged at the bottom of the water discharge electromagnetic valve, and the electric control device is connected with the water discharge electromagnetic valve. During operation of the filter, the filter can automatically discharge water when water in the settling cup reaches the preset water discharge level, water discharge is automatically stopped when the water level drops to the preset stop water level, so that the negative impact caused by untimely water discharge is prevented.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to the water discharge technology. Background technique [0002] The bottom of the filter is connected with a sedimentation cup, and the sedimentation cup is connected with a drain valve. When the filter is in use, the filter keeps separating water, and the separated water is concentrated in the sedimentation cup. When the water in the sedimentation cup exceeds the predetermined water level, it is necessary to open the drain valve to discharge the water. [0003] The existing filter does not have the function of automatically draining water, and it is necessary to manually observe the water level and manually open the drain valve to drain water; this cannot avoid the phenomenon of untimely draining of water, which will bring troubles to the normal work of devices using filters (such as motor vehicles or ships). to negative impact.
