Description

Technical Field

[0001] This utility model relates to a method for cooling spiral ribbons, and more specifically to the stirring and cooling of powders, and to a double-layer spiral ribbon powder cooling mechanism. Background Technology

[0002] In industrial production, the cooling of powder materials is a crucial step in ensuring product quality, safety, and process efficiency. Powders typically refer to granular or powdery substances. Their physical properties, such as flowability, heat capacity, and large surface area, make them prone to problems such as uneven temperature distribution, agglomeration, oxidation, or thermal decomposition during cooling. Cooling technology is widely used in chemical, food, pharmaceutical, and metallurgical industries to prevent oxidation, decomposition, and agglomeration by reducing powder temperature, while simultaneously meeting the stringent temperature requirements of subsequent processing.

[0003] Double-layer spiral ribbon is a common powder handling device. Its core principle is to drive the powder to circulate in the cooling chamber through the rotation of the spiral blades, thereby achieving full contact with the cooling medium (such as air, water or liquid nitrogen).

[0004] Traditional cooling technologies often rely on simple heat dissipation structures or external cooling media, which are insufficient to meet the rapid and uniform cooling requirements of highly heat-sensitive powders. Furthermore, powder materials are prone to agglomeration during heat dissipation. Therefore, developing an efficient and stable powder cooling mechanism is of great significance. Utility Model Content

[0005] One objective of this invention is to provide a new technical solution for a double-layer spiral ribbon powder cooling mechanism.

[0006] According to a first aspect of the present invention, a double-layer spiral ribbon powder cooling mechanism is provided, comprising an outer shell, a first shaft and a second shaft movably disposed on both sides of the inner side of the outer shell, a connecting plate fixedly disposed on the inner side of both the first shaft and the second shaft, two stirring belts fixedly disposed between the two connecting plates, and an elliptical ring fixedly disposed between the two stirring belts, wherein four elliptical rings are provided, and two sets of elliptical rings are fixedly disposed together, and two interconnected elliptical rings are respectively fixed between the two ends of the two stirring belts;

[0007] An embedded rod is movably installed inside the second shaft. A heat exchange plate is provided on one side of the embedded rod, and the other end of the heat exchange plate is movably connected inside the first shaft. The heat exchange plate is located between the two stirring bands. A coiled heat exchange tube is embedded inside the heat exchange plate. The two ends of the heat exchange tube are respectively connected to a cold water pipe and a hot water pipe. The cold water pipe and the hot water pipe are embedded inside the embedded rod.

[0008] Furthermore, a first bevel gear is keyed to the outside of the outer casing of the first shaft, and a second bevel gear is meshed with the first bevel gear.

[0009] Furthermore, a gear box is provided at one end of the outer casing, and a reinforcing plate is welded to the bottom of the gear box. The first bevel gear and the second bevel gear are movably located inside the gear box.

[0010] Furthermore, a servo motor is mounted on the upper end of the gearbox, the output end of the servo motor is connected to an output shaft, the second bevel gear is keyed to the output shaft, and the bottom end of the output shaft is movably connected to the bottom of the gearbox.

[0011] Furthermore, a bearing cap is fixedly installed at the other end of the outer casing, one end of the second shaft passes through the outer casing and is movably connected to the bearing cap, and the embedded rod passes through the bearing cap and the second shaft.

[0012] Furthermore, a top cover is fixedly installed on the upper end of the outer shell by fixing bolts, a feed pipe is connected in the middle of the top cover, and opening and closing covers are movably connected to both sides of the top cover.

[0013] Furthermore, a discharge pipe is connected to the bottom center of the outer casing, and an opening and closing valve plate is movably installed inside the discharge pipe.

[0014] Furthermore, a mounting plate is welded to one side of the discharge pipe, and a servo electric cylinder is fixedly mounted on the mounting plate.

[0015] Furthermore, a connecting rod is fixedly provided at the end of the telescopic rod of the servo electric cylinder, and one end of the connecting rod is fixedly connected to the end of the opening and closing valve plate.

[0016] Furthermore, support legs are welded to both ends of the bottom of the outer casing, and the height of the support legs is greater than the height of the discharge pipe.

[0017] According to one embodiment of this disclosure, the cooling mechanism connects the stirring belt through connecting plates at both ends, and adopts a double-layer stirring belt, with an elliptical ring between the double-layer stirring belt. The double-layer stirring belt and the elliptical ring are used to mix and stir the powder material, preventing the powder material from agglomerating due to uneven heat dissipation during the heat dissipation process, and maintaining the uniformity of heat dissipation of the powder material.

[0018] A heat exchange plate is provided between the double-layer stirring belt and the elliptical ring. The heat exchange plate dissipates heat from the powder material. That is, the stirring belt and the elliptical ring mix and stir the powder material, and can turn the powder material over so that the powder material can come into contact with the heat exchange plate, which facilitates heat exchange treatment of the powder material.

[0019] Furthermore, heat exchange tubes are embedded inside the heat exchange plate. Cooling water is transported through cold water pipes and hot water pipes at the ends of the heat exchange tubes. That is, cooling water is input into the heat exchange tubes through the cold water pipes, and then exchanges heat with the powder material through the heat exchange plate. The cooling water that has absorbed heat is discharged from the hot water pipes, which can realize the circulating heat exchange process and achieve heat exchange with the powder material.

[0053] The specific operational procedures for this application are as follows:

[0054] In use, the device is connected to an external circulating water cooling system via cold water pipe 10 and hot water pipe 11, facilitating the circulation of cooling water into the heat exchange tube 9. The powder material is then fed into the outer casing 1 through the feed pipe 20. The servo motor 14 is then activated, driving the first shaft 2 to rotate via the output shaft 15, the second bevel gear 16, and the first bevel gear 13. The first shaft 2, through the stirring belt 5, drives the second shaft 4 at the other end to rotate, thereby enabling the double-layered stirring belt 5 to agitate the powder material inside the outer casing 1. The mixing belt 5 has multiple elliptical rings 6 between it and the double-layered mixing belt 5. When the mixing belt 5 rotates, it carries the powder material, allowing the powder material to come into contact with the heat exchange plate 7, which facilitates heat exchange treatment of the powder material. The embedded rod 8 passes through the bearing cap 12 and the second shaft 4 and does not rotate with the mixing belt 5. This allows the heat exchange plate 7 to be set perpendicular to the outer shell 1, preventing the powder material from turning over or causing mixing blockage. It also facilitates contact between the powder material and the heat exchange plate 7, achieving cooling and mixing of the powder material. During cooling, the powder material will not clump together.
