Abstract
Spent surface finishing compound is filtered and cooled or heated for reuse in a machine finishing process. The spent finishing compound is filtered through a pleated polyester or polypropylene wound filter cartridge to remove particles of a predetermined size ranging from about 0.5 to 100 microns. The surface finishing compound circulates through an in-line, constant flow intercooler having a chamber for receiving and maintaining the finishing compound in a spiral circulation. The surface finishing compound circulates about cooling tubes positioned within the chamber. Heat is exchanged between the circulating water within the cooling tubes and the surface finishing compound.
Claims9
A method for recycling spent finishing compounds used in surface machine finishing processes, comprising the steps of:
- a. collecting the spent finishing compound used in a surface machine finishing process;
- b. filtering the spent finishing compound to remove particles of a predetermined size ranging from about 0.1 to 100 microns;
- c. transferring the spent finishing compound through an in-line, constant flow intercooler having a chamber for receiving and maintaining the finishing compound in a spiral circulation and having cooling tubes;
- d. circulating fluid having a preset temperature from a temperature control unit to the cooling tubes of the intercooler about which the finishing compound circulates to change the temperature of the finishing compound to a predetermined level;
- and
- e. returning the finishing compound to the surface machine finishing process.
The method according to claim wherein the spent finishing compound is filtered to remove particles of a predetermined size ranging from about 20 to 50 microns.
