Technical Field

[0001] The utility model relates to the technical field of sintering furnaces, in particular to a ventilator for a sintering furnace. Background Art

[0002] A sintering furnace refers to a special equipment that allows powder compacts to obtain the desired physical, mechanical properties and microstructure through sintering. The current sintering furnace is mainly used to dry the slurry on the silicon wafer, remove the organic components in the slurry, and complete the sintering of the aluminum back field and gate lines.

[0003] At present, a sintering furnace needs ventilation during the combustion process to ensure that there is sufficient oxygen in the furnace, so as to keep the gas in the sintering furnace stable. However, since the temperature in the sintering furnace is relatively high during operation, the use of a ventilator for gas replenishment is likely to cause heat recoil in the airflow, which not only causes a waste of heat energy, but also the heat will cause the temperature of the ventilator to rise, which is likely to cause high temperature and affect the service life of the ventilator. For this reason, a ventilator for a sintering furnace is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when using a ventilator to supplement gas, heat recoil in the airflow is easily caused, and the heat causes the temperature of the ventilator to rise, which easily causes high temperature and affects the service life of the ventilator. The utility model provides a ventilator for a sintering furnace.

[0023] like Figure 1-4 As shown, a ventilator for a sintering furnace includes a fan body 1. An auxiliary cooling mechanism is arranged on the side wall of the fan body 1. The auxiliary cooling mechanism includes an annular cooling box 4. The annular cooling box 4 is fixedly mounted on the outer wall of the fan body 1, and a liquid exchange pipe 5 is symmetrically mounted on the side wall of the annular cooling box 4. Cooling water can be injected into the annular cooling box 4 through the arranged liquid exchange pipe 5, thereby improving the cooling effect of the fan body 1 and avoiding a rapid increase in temperature of the fan body 1 during ventilation.

[0024] An air outlet pipe 3 is fixedly installed on one side of the fan body 1, and an air box 6 is arranged at one end of the air outlet pipe 3. A connecting mechanism is arranged on one side of the air box 6, and the connecting mechanism includes a connecting pipe 7. One end of the connecting pipe 7 is fixedly installed on the air box 6, and the other end of the connecting pipe 7 is fixedly installed on the air supply box 8. The air box 6 and the air supply box 8 are connected through the connecting pipe 7. A ventilation electric control valve 9 is arranged on the side wall of the connecting pipe 7. The ventilation electric control valve 9 can further cut off the connection between the air supply source and the fan body 1 and the air in the sintering furnace, thereby achieving a good heat isolation effect.

[0025] An air supply box 8 is provided at one end of the connecting pipe 7, an air intake pipe 2 is fixedly installed on the other side of the fan body 1, and an air supply box 10 is provided at one end of the air intake pipe 2. A reverse heat control mechanism 13 is provided in the air supply box 10 and the air supply box 8. The reverse heat control mechanism 13 includes a sealing ring 1301, a support frame 1303 is fixedly installed on one side of the sealing ring 1301, and a spring telescopic column 1302 is fixedly installed on the support frame 1303, and a reverse partition plate 1304 is fixedly installed on one end of the spring telescopic column 1302. When maintaining the gas balance in the sintering furnace, the generated gas pressure will push open the reverse partition plate 1304 on the sealing ring 1301, so that the gas enters the sintering furnace for gas balance, and then the reverse partition plate 1304 set by the heat-resistant material will block the sealing ring 1301 again under the drive of the spring telescopic column 1302, thereby blocking the recoil of the hot air flow, which can effectively reduce the heat loss in the sintering furnace.

[0026] The reverse partition plate 1304 in the air supply box 8 is set to a heat-resistant material, which can further improve the heat insulation effect, and a filter screen is set between the reverse partition plate 1304 and the blocking ring 1301, so that the dust and impurities in the recoil gas can be effectively blocked by the filter screen, thereby preventing them from recoil into the air supply box 8. The reverse partition plate 1304 in the air supply box 10 is provided with a sealing gasket, and the sealing gasket is set between the reverse partition plate 1304 and the blocking ring 1301. The sealing gasket can further increase the sealing effect between the two. A connecting pipe 11 is fixedly installed at one end of the air supply box 10, and a gas supply electric control valve 12 is set on the connecting pipe 11.

[0027] In summary: when supplying gas to the sintering furnace, first open the gas supply electric control valve 12 on the connecting pipe 11, and then start the fan body 1 to generate negative pressure in the gas supply box 10, so that the gas supply source will allow the gas to enter the gas supply box 10 under the action of negative pressure, and then open the ventilation electric control valve 9 on the connecting pipe 7, so that the gas will pass through the fan body 1 and enter the gas storage box 6 for storage, thereby maintaining the air pressure balance in the gas supply box 10 and the gas storage box 6, and then when the air pressure continues to increase, the generated gas pressure will push open the gas supply box 10. The reverse partition plate 1304 on the sealing ring 1301 in the box 8 allows the gas to enter the sintering furnace for gas balance, and then the reverse partition plate 1304 set with the heat-resistant material will block the sealing ring 1301 again under the drive of the spring telescopic column 1302, thereby blocking the recoil of the hot air flow, and then driven by the fan body 1, the reverse partition plate 1304 will intermittently open to replenish gas, and then the exhaust gas in the sintering furnace will be discharged through the original gas exhaust structure, thus maintaining the gas balance in the sintering furnace.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
