Glass beads are placed in the feeding barrel 3, and the materials in the feeding barrel 3 are pushed by an auger. The outer wall of the feeding barrel 3 is heated by the gas pipe 4. The feeding barrel 3 is rotated to transfer heat to the glass beads. At the same time, the hot air flow in the heating chamber 14 flows along the exhaust pipe 5, and the water in the annular heat absorption chamber 16 absorbs the heat of the exhaust pipe 5, thereby realizing heat energy recovery. The water inlet pipe 13 is connected to a water source, and the water in the annular heat absorption chamber 16 is discharged by the water outlet pipe 17 to realize heat energy recovery.

[0024] As a technical solution further provided by the utility model, a feed hopper 11 is fixedly installed on the furnace body 1, and the first end of the feeding tube 3 is connected to the feed hopper 11, a plurality of discharge ports 32 are provided on the inner wall of the feeding tube 3 near the second end, and a discharge port 12 is provided on the furnace body 1 which is intermittently connected to the discharge port 32.

[0025] Specifically, Figure 3 As shown, the material in the feeding barrel 3 is intermittently connected to the discharge port 12 along the discharge port 32 by using the auger to achieve the effect of discharging. The material is poured into the feed hopper 11, and then slides into the feeding barrel 3 through the feed hopper 11.

[0026] Furthermore, the auger includes a main shaft 21 rotatably mounted on the second end of the feed tube 3 and a spiral blade 22 fixedly mounted on the outer wall of the main shaft 21 , and the output end of the main motor 2 fixedly mounted in the furnace body 1 is fixedly mounted on the first end of the main shaft 21 .

[0027] Specifically, the main motor 2 is used to drive the main shaft 21 to rotate, so that the spiral blades 22 push the material in the barrel 3 to move to the discharge port 32 .

[0028] Furthermore, the second end of the feed barrel 3 is movably provided with a planetary gear consisting of a cylindrical gear 23, a sun gear 24 and a planetary gear 25. The planetary gear 25 is fixedly mounted on the outer wall of the main shaft 21, the cylindrical gear 23 is fixedly mounted on the outer wall of the feed barrel 3, and the sun gear 24 is respectively meshed with the cylindrical gear 23 and the planetary gear 25.

[0029] Specifically, when the main motor 2 drives the main shaft 21 to rotate, the planetary gear 25 on the main shaft 21 meshes with the sun gear 24, so that the sun gear 24 rotates and meshes with the cylindrical gear 23. At this time, the cylindrical gear 23 drives the feeding barrel 3 to rotate, and then the main motor 2 drives the feeding barrel 3 to rotate while driving the spiral blade 22 to push the material in the barrel 3.

[0030] Furthermore, a vacuum chamber 15 is provided in the furnace body 1 , and a temperature insulation pad 6 is fixedly installed in the furnace body 1 , and the temperature insulation pad 6 is located between the vacuum chamber 15 and the annular heat absorption chamber 16 .

[0031] Specifically, the vacuum chamber 15 is used to insulate the heating chamber 14 and the annular heat absorption chamber 16, thereby reducing the heat in the heating chamber 14 being absorbed by the water in the annular heat absorption chamber 16, so as to affect the heating of the feeding tube 3 in the heating chamber 14, and the insulation pad 6 is used to further insulate the heating chamber 14 and the annular heat absorption chamber 16, so as to achieve the effect of keeping the heating chamber 14 warm.

[0032] Furthermore, a plurality of combustion ports 41 facing the feed tube 3 are provided on the outer wall of the gas pipe 4 , and a gas supply pipe 7 is fixedly connected to the inner wall of one side of the heating chamber 14 .

[0033] Specifically, the feed barrel 3 is heated by utilizing the flame ejected from the burner 41, and then the gas blown in through the air supply pipe 7 is used to assist the combustion of the burner 41. At the same time, the air blown into the heating chamber 14 will push the hot air flow in the heating chamber 14 into the exhaust pipe 5.

[0034] Furthermore, a spiral plate 31 is fixedly mounted on the outer wall of the feeding cylinder 3 .

[0035] Specifically, the spiral plate 31 on the outer wall of the feeding barrel 3 is used to make the hot air flow in the heating chamber 14 flow along the spiral plate 31. As the feeding barrel 3 rotates, the heat below the feeding barrel 3 is transferred to the top of the feeding barrel 3, thereby enhancing the uniformity of heating of the feeding barrel 3.

[0036] Furthermore, the exhaust pipe 5 is a stainless steel pipe.

[0037] Working principle: The material is poured into the feed hopper 11, and then slides into the feed barrel 3 through the feed hopper 11. When the main motor 2 drives the main shaft 21 to rotate, the planetary gear 25 on the main shaft 21 meshes with the sun gear 24, so that the sun gear 24 rotates and meshes with the cylindrical gear 23. At this time, the cylindrical gear 23 drives the feed barrel 3 to rotate, and then the main motor 2 drives the feed barrel 3 to rotate while driving the spiral blade 22 to push the material in the barrel 3. The feed barrel 3 is heated by the flame ejected from the burner 41, and then the gas blown in by the air supply pipe 7 is used to assist the burner 41. At the same time, the air blown into the heating chamber 14 will push the hot air flow in the heating chamber 14 into the exhaust pipe 5. The water in the annular heat absorption chamber 16 absorbs the heat of the exhaust pipe 5, thereby realizing the recovery of heat energy. The water inlet pipe 13 is connected to the water source, and then the water in the annular heat absorption chamber 16 is discharged by the water outlet pipe 17 to realize the recovery of heat energy.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
