Description

TECHNICAL FIELD The present invention relates to a drying device for beads which are solid particles used in a paint dispersing device to help the dispersion of a pigment in a solvent.

2. Description of the Related Art Conventionally, a simple container has been used as this type of bead drying device.

Problems to be Solved by the Invention In such a conventional simple container, since a large amount of beads taken out from the paint dispersing device and still wet with a solvent such as toluene is dried in the sun, it takes at least about one day. Took a long time. In addition, the solvent evaporates and diffuses, causing a fire and a danger to human health.

The present invention solves such a problem, and provides an efficient and complete bead drying apparatus.

Means for Solving the Problem In order to solve this problem, the bead drying device of the present invention is
The container is divided into upper and lower parts by a net, air is sucked out from the space under the net by a suction cylinder, a bead outlet is provided on the side surface of the container just above the net, and a solvent outlet is provided at the bottom of the container. Is provided.

Action With this configuration, air is sucked into the suction cylinder through the gaps between the wet beads injected into the upper part of the net of the container, under the net, and is then forcibly dried by the air flow. It Further, the evaporated solvent does not diffuse or leak to the vicinity due to the air flow as described above. Further, the dried beads can be easily taken out through the take-out port, and the solvent that has been dropped and accumulated on the bottom of the container can be taken out through the take-out port.

Embodiment FIG. 1 is a sectional view showing a bead dryer according to an embodiment of the present invention. In the figure, the container 1 has a bottom 2 and a side surface 3, and the container 1 is divided into upper and lower parts by a net 4 having a number 20 of stainless steel. Reference numeral 5 is an intake cylinder, and an opening 6 is provided in the bottom of the intake cylinder 5. The entire intake cylinder 5 penetrates the mesh 4 and is fixed to the center of the container 1. An outlet 7 is provided on the side surface 3 of the container 1 immediately above the net 4, and an outlet 8 is provided on the bottom 2 thereof, each of which is closed by a screw lid. Casters 10 are attached to the lower ends of the legs 9 to facilitate movement of the entire apparatus. 11 is a bead.

In the paint dispersion device, solid particles such as soda glass particles, that is, beads, are gradually worn away and reduced by operation of the device or broken into small pieces. Therefore, it is necessary to periodically take out the beads from the device, screen the beads, select only those having a certain size or more, and further weigh the amount to make up for the deficiency. To do this, the beads that are wet with solvent must be dried so that they can easily pass through the screen and be weighed.

Then, the wet beads 11 taken out from the paint dispersing device
Is put into the container 1 from above, and the air is sucked by connecting the upper end of the suction cylinder 5 to a blower while keeping the outlet 7 and the outlet 8 sealed. Then, as shown by the arrow, the air passes through the gaps between the wet beads 11 and escapes under the net 4 while evaporating the solvent. Further, it enters the suction cylinder 5 through the opening 6 and is guided to the outside or a solvent recovery device.

This downward flow of air also assists the dripping of the solvent that wets the beads 11 by gravity, so that the solvent quickly accumulates at the bottom of the container 1. Therefore, the extraction port 8 is opened as appropriate, and the accumulated solvent is extracted and collected.

Since the entire apparatus is configured to absorb air, there is no risk that the evaporated solvent will diffuse or leak out of the apparatus. Therefore, there is no risk of ignition or the health of workers near the equipment.

When the drying is completed, the spherical beads are generally used, and thus the beads have good fluidity when dried, and therefore the beads can be transferred to a container such as a bucket very easily by opening the outlet 7. There is no need to lift the container or spill the beads during transfer, as in the case of using a conventional simple container.

Using this device, the time required for drying the beads can be shortened to about 2 to 3 hours.

Effects of the Invention As described above, according to the present invention, it is possible to safely dry beads wet with a solvent in a short time.
