Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-4 The cooling structure shown is for a vitrification furnace for hollow glass microspheres, applied to the furnace body 1, and includes:

[0022] The cooling mechanism includes a water-cooling component 2 located in the middle of the vitrification furnace body 1 and an air-cooling component 3 located on the top of the vitrification furnace body 1. The water-cooling component 2 and the air-cooling component 3 are used to reduce the temperature inside the vitrification furnace body 1.

[0023] Fixed sleeve 4 is fitted on the top of the vitrification furnace body 1 and is used to restrict the movement of the cooling mechanism.

[0024] Specifically, the water-cooling component 2 includes a water-cooling pipe 201 sleeved on the outer wall of the vitrification furnace body 1. One end of the water-cooling pipe 201 is provided with a water outlet pipe 202, and the other end of the water-cooling pipe 201 is provided with a water inlet pipe 203. One end of the water inlet pipe 203 is provided with a water pump 204, and the input end of the water pump 204 is provided with a water supply pipe 205.

[0025] It should be noted that the water pump 204 is an existing centrifugal pump, and its input water pipe 205 is used to connect to the water storage tank. The water cooling pipe 201 is arranged in a loop around the middle of the vitrification furnace body 1. The two ends of the water inlet pipe 203 are connected to the water pump 204 and the water cooling pipe 201 respectively through connecting flanges. One end of the water outlet pipe 202 is connected to the water cooling pipe 201 through a connecting flange, and the other end is connected to the water storage tank. In use, the water pump 204 inputs water from the water storage tank into the water cooling pipe 201, and the water cooling pipe 201 cools the vitrification furnace body 1.

[0026] Specifically, the air-cooling component 3 includes an air supply connector 303 located on the back of the vitrification furnace body 1. One end of the air supply connector 303 is provided with an air supply pipe 302, and one end of the air supply pipe 302 is provided with a fan 301. The top of the vitrification furnace body 1 is provided with an exhaust pipe 304, which is used for exhausting air.

[0027] It should be noted that the fan 301 is the existing centrifugal fan 301, which is a device that uses rotating blades to convert mechanical energy into gas kinetic energy and pressure energy. Its core principle is based on Bernoulli's equation and impeller dynamics. When the motor or engine drives the impeller to rotate, the gas between the blades is accelerated and thrown out by centrifugal force or axial force, forming a low-pressure zone to draw in new gas, thereby realizing continuous gas delivery. The centrifugal fan 301 pressurizes the gas through radial centrifugal force, while the axial fan 301 pushes the gas along the axial direction. Both increase the gas pressure or flow rate through kinetic energy conversion. In use, the gas is input into the interior of the vitrification furnace body 1 through the fan 301 and the gas delivery pipe 302. The gas reduces the temperature inside the vitrification furnace body 1, and finally the gas is discharged through the gas outlet pipe 304 at the top of the vitrification furnace body 1.

[0028] Specifically, the inner wall of the middle part of the fixed sleeve 4 is provided with an installation cavity 401, and the water cooling pipe 201 is inserted and connected inside the installation cavity 401. The inner wall of one side of the installation cavity 401 is provided with a first through hole 402, and the water cooling pipe 201 is inserted and connected inside the first through hole 402. The back of the fixed sleeve 4 is provided with a second through hole 403, and the gas supply connector 303 is inserted and connected inside the second through hole 403.

[0029] It should be noted that the fixed sleeve 4 is fixedly sleeved on the outer wall of the vitrification furnace body 1, and the horizontal cross section of the installation cavity 401 is set as an annular shape. The fixed sleeve 4 restricts the position of the water cooling pipe 201 to prevent the water cooling pipe 201 from shaking randomly.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
