Title:
COOLING WATER FILTERING AND CIRCULATING DEVICE FOR ROAD SURFACE CUTTING MACHINE
Document Type and Number:
Japanese Patent JP3447695
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the number of machines or parts by imparting a plurality of functions to one pump to achieve miniaturization and to realize efficient filtering and circulation.
SOLUTION: A cooling water filtering and circulating device A has a pump 1, a filtering treatment part 3 for filtering sludge-containing turbid water, which is sent under pressure, under pressure to separate the same into sludge and water, a filtering treatment tank 2 housing the filtering treatment part 3 to form a stagnation part of separated water, a container 8 housing separated sludge and a fresh water tank 7 housing separated water. Either one of a turbid water pressure sending route communicating with the freely hermetically closed and opened filtering treatment part 3 and a sludge discharge route 15 communicating with the container 8 housing the sludge S is selectively connected to the pressure feed side of the pump 1 and either one of a turbid water suction route 12 and the sludge suction route 13 communicating with the filtering treatment part 3 is selectively connected to the suction side of the pump 1 and a cooling water supply pipe 9 communicating with a road surface cutting machine 5 is connected to a fresh water tank 4.
