Problems solved by technology

[0005] Since the conventional deliquoring and solidifying device sends compressed air into the pressurized container to deliquify and solidify the sludge while compressing it, the sludge is consolidated while strongly adhering to the inner peripheral surface of the pressurized container, Sometimes the sludge cannot be taken out from the pressurized container even if the lid is opened
When this phenomenon occurs, the device has to be stopped and the sludge is taken out manually, which requires unnecessary troublesome work and time

Abstract

The invention provides a sludge dehydration and solidification device, which can reliably take out solidified sludge from a processing container. The deliquification and solidification device (10) of sludge comprises: a processing container (12), which is introduced into the liquid containing sludge, and has a discharge port (12d) at the lower end; a cover body (21), which closes the discharge port (12d), It also has a filter element (23) that allows the liquid introduced into the processing container (12) to pass through and accumulate sludge; an opening and closing drive unit (22) that moves the cover (21) to open and close the discharge port (12d); liquid removal And solidification mechanism (16), the sludge on the filter element (23) is deliquored and solidified; ) to extrude.

Description

technical field [0001] The present invention relates to a dehydration and solidification device for removing sludge such as machining chips from a liquid such as a cooling medium supplied to a machine tool, and deliquidizing and solidifying the sludge. Background technique [0002] Generally, in machine tools such as a honing machine and a grinding machine, a workpiece (workpiece) placed in a machining section is processed while being supplied with a cooling medium such as a polishing fluid or a cutting fluid. Furthermore, machining chips of the workpiece generated during machining are collected together with the cooling medium. The recovered used cooling medium is filtered by a filter device to remove processing debris and reused. [0003] The following Patent Document 1 discloses a device for dehydrating and solidifying sludge of processing chips removed by a filter device. The liquid removal and solidification device includes a pressurized container with an open bottom,...
