Abstract
Description
Technical Field
[0001] This utility model relates to the field of barbecue technology, specifically a cooling device for a powder physicalization furnace. Background Technology
[0002] The rapid development of the electronic information industry has driven the continuous expansion of the integrated circuit market. As a filler material for epoxy molding compounds used in integrated circuit packaging, silicon micropowder has also shown broad development prospects. However, the quality requirements for silicon micropowder are becoming increasingly stringent. In addition to requiring ultrafine particles, high purity, and low radioactive element content, spherical particle shape is also a particular requirement. The high-temperature melting method of silica uses angular silicon micropowder as raw material. Natural gas or liquefied petroleum gas is mixed and burned with pure oxygen in a spheroidizing furnace using a burner to generate a high temperature of over 2000°C, which completely melts the angular quartz particles. The molten quartz particles are spheroidized under the action of surface tension, and then rapidly cooled to obtain spherical silicon micropowder products.
[0003] Currently, the rapid cooling of molten quartz particles generally involves directly introducing cold air through an air inlet pipe to quickly cool the molten quartz particles and shape them rapidly. However, this direct airflow method results in uneven cooling within the furnace, leading to poor cooling performance. Furthermore, the high air velocity at the outlet of this air supply method can easily blow products towards the furnace wall, causing deformation of the silicon micropowder and reducing the yield rate. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a cooling device for a powder physicochemical furnace to address the shortcomings of the prior art, thereby solving at least one of the above-mentioned technical problems.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A cooling device for a powder physicochemical furnace includes a furnace body with openings at the top and bottom. A flange is provided at the upper opening of the furnace body, and a discharge port is provided at the bottom opening of the furnace body. An annular air collecting chamber is provided on the side of the furnace body. Several air holes are provided inside the furnace body. A spiral cooling coil is provided in the air collecting chamber. A liquid inlet pipe is provided at the upper part of the air collecting chamber and is connected to the upper end of the cooling coil. A liquid outlet pipe is provided at the lower part of the air collecting chamber and is connected to the lower end of the cooling coil. Several sets of cooling air duct assemblies are evenly arranged in the air collecting chamber. Each cooling air duct assembly includes an air collecting pipe. The air collecting pipe is vertically arranged and has an air duct connector at its bottom. Several air inlet pipes are connected to the side of the air collecting pipe. The end of the air inlet pipe is located inside the air collecting chamber. An air outlet is provided at the end of the air inlet pipe and is horizontally 90 degrees to the air collecting pipe.
[0006] Specifically, the discharge port has a converging funnel-shaped structure.
[0007] Specifically, each of the air vents is set up in a corresponding air collection chamber.

The furnace body with its uniform air vents and the curved air outlet prevents direct airflow into the furnace, avoiding blowing silicon powder onto the furnace walls.

[0026] Example 1: See Figures 1 to 3 This is a schematic diagram of the structure of this utility model, including a furnace body 1. The furnace body 1 has openings at the top and bottom. A flange 2 is installed at the top opening of the furnace body 1 for connection to a spheroidizing furnace. The spheroidizing furnace completely melts the angular quartz particles. The molten quartz particles are spheroidized under the action of surface tension and fall into the furnace body 1 for cooling. A discharge port 3 is installed at the bottom opening of the furnace body 1 for discharging materials. An annular air collecting chamber 4 is installed on the side of the furnace body 1. Several air holes 5 are installed inside the furnace body 1. Cold air first enters the air collecting chamber 4 for buffering and then enters the interior of the furnace body 1 evenly through the air holes 5. A spiral cooling coil 6 is installed inside the air collecting chamber 4. A liquid inlet pipe 7 is installed at the upper part of the air collecting chamber 4 and is connected to the upper end of the cooling coil 6. An outlet is installed at the lower part of the air collecting chamber 4. The liquid pipe 8 and the outlet pipe 8 are connected to the lower end of the cooling coil 6. The cooling coil 6 is connected to an external coolant device. The coolant device pumps coolant into the cooling coil 6. The coolant flows in the cooling coil 6 to cool the cold air in the air collecting chamber 4 a second time. The air collecting chamber 4 is evenly provided with several sets of cooling air duct assemblies. The cooling air duct assembly includes an air collecting pipe 11. The air collecting pipe 11 is set vertically. The bottom of the air collecting pipe 11 is provided with an air duct connector 12. The air duct connector 12 is connected to the cold air blower through a pipe. Several air inlet pipes 9 are connected to the side of the air collecting pipe 11. The end of the air inlet pipe 9 is set inside the air collecting chamber 4. The end of the air inlet pipe 9 is provided with an air outlet 10. The air outlet 10 is set at a horizontal 90-degree angle to the air collecting pipe 11 to avoid the cold air blowing directly into the air hole 5, which would cause uneven airflow in the air hole 5.
[0027] Specifically, the discharge port 3 has a converging funnel-shaped structure, which facilitates the discharge of materials.
[0028] Specifically, several air holes 5 are provided corresponding to the air collection chamber 4, and the air in the air collection chamber 4 enters the interior of the furnace body 1 through the air holes 5.
[0029] Specifically, the air holes 5 are distributed in a grid pattern, with the interval between adjacent air holes 5 being less than 10 centimeters, so that the cold air inside the furnace body 1 is uniform. The air holes 5 are dense and the air is discharged evenly, which can reduce the probability of material contacting the side wall of the furnace body 1.
[0030] Specifically, both the inlet pipe 7 and the outlet pipe 8 are equipped with liquid pipe joints at their ends, which are connected to the coolant device through pipes.
[0031] Specifically, the cooling coil 6 is a rigid tube, and a support frame is installed inside the air collection chamber 4. The support frame is connected to the cooling coil 6 and supports the cooling coil 6.
[0032] Specifically, several air outlets 10 are arranged in the same direction, that is, several air outlets 10 are arranged clockwise or counterclockwise, so that the air in the air collection chamber 4 forms a spiral shape, avoiding cold air blowing directly into the air hole 5.
[0033] The working principle of this utility model:
[0034] Flange 2 is connected to the spheroidizing furnace. The coolant device is started, and the coolant is pumped into the cooling coil 6. The coolant circulates in the cooling coil 6 and the coolant device. The cold air blower is connected to the air duct connector 12. The cold air blower is started to supply air into the air collecting chamber 4. The cold air in the air collecting chamber 4 is blown evenly into the interior of the furnace body 1 through the air holes 5. The spheroidizing furnace completely melts the angular quartz particles. The molten quartz particles are spheroidized under the action of surface tension and fall into the furnace body 1 for cooling. The cold air enters the furnace body 1 to cool the molten quartz particles, so that the quartz particles are formed. The formed material is discharged through the discharge port 3.
[0035] This invention features a furnace body 1 with uniform air holes 5, which allows for more uniform cold air intake and improves cooling efficiency. The furnace body 1 with uniform air holes 5 and the bent air outlet 10 prevent direct airflow into the furnace body 1, thus avoiding blowing silicon powder onto the furnace wall. Simultaneously, the uniform air holes 5 prevent silicon powder from contacting the furnace wall, improving yield. Furthermore, the device incorporates a cooling coil 6 for secondary cooling of the cold air, further reducing its temperature and enhancing cooling effectiveness.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
[0037] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
