The present invention relates to a glass bead molding apparatus designed to reuse the heat generated during the molding of glass beads (GLASS BEADS) to the mixed air, and to convert it to heat for heating.

Conventional glass bead molding apparatus is a glass bead raw material (powder) is injected into the supply cylinder with the bottom of the cone-shaped through the raw material supply pipe, when the bottom of the cylinder hit by a vibrating motor, a plurality of input pipes provided on both outer peripheral surfaces of the supply cylinder Through the glass bead raw material is formed into a spherical glass ball in the combustion chamber in the vertical furnace to be discharged out through the outlet hole at the bottom of the vertical furnace, the glass bead (glass grain) raised by the convection of heat continues to float As a result of stagnation or inflow into the suction pipe side installed at the upper part of the vertical molding furnace, a failure occurs, and the discharged heat is simply discharged through the suction pipe instead of circulating the elevated heat, thereby causing a waste of heat.

The present invention was devised to solve this problem, and in the vertical molding furnace in which the rotating plate and the motor are installed so that the glass bead raw material flowing from the supply pipe can be dispersed and dropped from the supply cylinder to each input pipe, the center of the vertical molding furnace The suction tube and the waste heat extraction tube are connected to the upper part, but the drawer hopper is installed on one side of the suction tube so that it can flow out to correspond to the conveyor belt, and a plurality of heat circulation tubes are installed on the outer peripheral surface of the vertical molding furnace so that the heat of the combustion chamber The heat supply pipe is connected to the upper one side and connected to the mixed gas supply pipe in which air and gas at the lower side are mixed and conveyed, thereby improving the thermal efficiency of the combustion chamber and transferring the waste heat generated during the glass bead to a separate heat exchanger. It is invented so that it can be used as heating or drying heat by supply.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The supply pipe 2a communicates with the upper part of the raw material supply cylinder 2, and a plurality of input pipes 2b are installed in communication with the bottom circumferential surface and penetrates the upper part of the vertical molding furnace 1, and the distal end of the input pipe 2b has a combustion chamber ( In the glass bead forming apparatus in which the rotary plate 13 is adhered to the center of the bottom of the supply cylinder 2, and the motor 14 is installed at the bottom thereof, the suction pipe 3 is positioned on the center of the vertical forming furnace 1. ) Is installed, the withdrawal hopper (4) (4 ') is fixed to one side of the suction pipe (3) so that the lower end close to the conveyor belt 15, the suction pipe (3) above the withdrawal hopper (4) (4') The waste heat take-out pipe 5 communicated with) is connected to the heat exchanger 10, so that the suction fan 9 is provided at the center of the waste heat take-out pipe 5.

A plurality of heat circulation tubes 6 are mounted on the outer circumferential surface of the body of the vertical molding furnace 1, and a heat supply pipe 7 is installed on the outer circumferential surface of the upper side to communicate with the furnace, and the mixed gas supply pipe 8 at the bottom of the combustion chamber A is provided. Is connected to. A blow fan 11 is installed at the lower end of the heat supply pipe 7, and an outlet hole 1 ′ is formed at the lower end of the vertical molding furnace 1, and a support 12 is disposed at the bottom of the outlet hole 1 ′. Installed configuration.

Unexplained code 16 is installed so that the waste heat extraction pipe, heat supply pipe, heat circulation pipe is installed in communication with the wire mesh to prevent the glass bead inflow, 17 is the air blower, 18 is the gas supply pipe, 19 is the mixer, 20 is Glass beads (21) are the raw materials of glass beads.

According to the present invention constituted as described above, in order to mold the glass beads, the glass bead raw material 21 is introduced into the supply cylinder 2 through the raw material supply pipe 2a by a separate raw material supply conveyor (not shown). When the glass bead raw material 21 is introduced into the rotating plate 13 and the rotating plate 13 having a slope is rotated by the rotation of the motor 14, the glass bead raw material 21 is supplied to the supply cylinder 2. ) It is freely dropped in the hot gas stream on the combustion chamber (A) in the vertical forming furnace (1) through a plurality of input pipe (2b) sprayed on the floor and connected to the outer peripheral surface. When the glass bead raw material 21 falls through the inlet pipe 2b, it is agglomerated and prevents it from pouring out at once, and the inlet pipe 2b is made so that the raw material dispersion falls. It is bent into a mold.

At this time, the formation of the molten air flow zone of the combustion chamber is the gas LPG supplied from the gas supply pipe 18 and the air discharged from the blower 17 are mixed in the mixer 19 and the combustion chamber A through the mixed gas supply pipe 8. In the flame spraying, heat is a high heat energy of 1000 ℃ to 1300 ℃ band, so that the glass bead raw material 21 in the solid state freely dropped in the air flow in the combustion chamber (A) Melting Fusion that changes from a high temperature to a liquid state The glass beads 20 (glass grains) are formed through the process.

Since the molten glass beads 20 are attracted from the convection in the vertical forming furnace 1 and the suction 휀 9 of the waste heat drawing tube 5 in communication with the upper suction pipe 3 as shown in FIG. , The glass beads 20 are collected in the conveyor belt 15 by dropping the heavy weight in the vertical molding furnace 1 onto the support hole 12 through the bottom outlet hole 1 'of the molding furnace, The light ones are freely dropped into the take-out hoppers 4 and 4 'in the heavy order through the suction pipes 3, and are collected and transported to the conveyor belt 15 at the lower end.

At this time, the glass beads 20 may be selectively collected by corresponding to a separate container at the bottom of the outflow hole (1 ') and the extraction hopper (4) (4') from which the glass beads 20 are drawn out.

In addition, a plurality of thermal circulation pipes 6 penetrated in the side of the vertical forming furnace 1 to circulate the heat generated during the molding of the glass bead 20 is installed to penetrate the upper layer inside the vertical furnace in the upper part of the furnace Since the heat is supplied to the lower combustion chamber again, it promotes convection of heat in the vertical forming furnace, and by supplying the mixed gas supply pipe 8, the temperature of the air mixed gas is raised to generate flame in the combustion chamber A. It is possible to save the energy supplied to make it.

In addition, the present invention sucks heat into the suction fan (9) through the waste heat extraction pipe (5) installed to communicate with one side of the suction pipe (3) in order to efficiently use the heat generated during the molding of the glass bead (20) heat exchanger By supplying to (10), the water became heated and used as heating heat, or it became possible to use as drying heat of a drying chamber.
