Compressed air drying device
First Claim
1. A compressed air drying device comprising:
- a support base including an inlet of compressed air from a compressor, an outlet of the compressed air, and a discharge port of oil and water, the discharge port including a drain valve device;
a drying container, which is filled with a desiccant and is installed in the support base;
a case that covers the drying container and is coupled to the support base; and
an oil separating member accommodated between the drying container and the case,wherein the drying container includes an upper filter and a lower filter, and wherein the desiccant is filled between the upper filter and the lower filter,wherein the compressed air drying device is configured to;
in a loading operation, cause the desiccant to dry the compressed air introduced through the inlet and discharge the dried compressed air through the outlet, and,in an unloading operation, cause the compressed air to pass through the lower filter, the desiccant, and the upper filter in the drying container and the oil separating member to discharge oil and water collected by the lower filter, the desiccant, the upper filter, and the oil separating member from the discharge port,wherein at least one of the lower filter and the upper filter is a glass fiber filter,wherein the oil separating member is configured to capture oil particles having a first range of particle diameters, andwherein the upper filter and the lower filter are configured to capture oil particles having a second range of particle diameters.

Abstract
A compressed air drying device includes a support base including an inlet of compressed air from a compressor, an outlet of the compressed air, and a discharge port of oil and water. The discharge port includes a drain valve device and a drying container. The container is filled with desiccant and is installed in the support base. In a loading operation, the compressed air drying device causes the desiccant to dry the compressed air introduced through the inlet and discharges the dried compressed air through the outlet. In an unloading operation, the compressed air drying device causes the compressed air to pass through the container to discharge oil and water from the discharge port. A glass fiber filter is provided at one or more of a position upstream of the desiccant and a position downstream of the desiccant in a flow of the compressed air during the loading operation.
