Water storage container

Abstract

The invention provides a water storage container which can avoid vortexes and can use a discharge pump to discharge water suitably. The water storage container (11) stores water provided form a water supply source and use the discharge pump (14) to discharge water to a water processing system. The water storage container (11) includes a container main body (41) for storing water provided from a water supply source according to a specified amount from a lower limit water level (L1) to an upper limit water level (L2), and using the discharge pump to discharge water out through a discharge opening (46) of a bottom plate (43); and a vortex prevention plate (47) for forming a size covering the discharge opening at a height under the lower limit water level and not contacting with the bottom plate of the container main body, and above the discharge opening so as to prevent vortexes while water stored in the container main body is discharged out of the discharge opening.

Description

technical field [0001] The present invention relates to a water storage container which stores water sent out by a delivery pump. Background technique [0002] Generally, processing devices such as grinding devices and cutting devices are connected to water treatment systems that supply processing water, cooling water for spindles, and the like (for example, refer to Patent Document 1). In the water treatment system, the water stored in the water storage tank is sent out by the delivery pump, and supplied as process water or cooling water to each part of the processing device. The amount of water stored in such a water storage container is managed, and the water level in the water storage container is usually kept at a predetermined water level or higher required for pumping out by a delivery pump. And, when the water level of the water storage tank falls below a predetermined water level, the supply of processing water or cooling water from the water storage tank to the pr...

AI Technical Summary

Problems solved by technology

However, when the water level in the water storage container is near the lower limit water level, a vortex will be generated due to the water flow toward the delivery port at the bottom of the water storage container, and air bubbles drawn from the water surface due to the vortex will be mixed into the delivery pump and In the flow path

There is a problem that the delivery pump is idling due to the mixing of air bubbles, so that the water cannot be delivered or sufficient delivery pressure cannot be obtained.
