Technical Field
[0001] This utility model relates to the field of photovoltaic technology, and more specifically to a heat field component—a crucible holder. Background Technology
[0002] The Czochralski method is a commonly used method for growing single crystals. Its working principle is to heat and melt the raw materials that make up the crystal in a crucible, and then pull the melt with a seed crystal on the surface of the melt. Under controlled conditions, the atoms or molecules of the seed crystal and the melt are continuously rearranged at the interface. As the temperature drops, the crystal gradually solidifies and grows into a single crystal. The purpose of this invention is to increase the stroke of the support rod and increase the amount of material fed. Utility Model Content
[0003] The purpose of this invention is to provide a crucible holder for releasing the travel of the support rod, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A crucible holder for releasing the stroke of a support rod includes a single crystal furnace mechanism. The single crystal furnace mechanism includes a single crystal furnace body, a top cover, a main body shell, and a working cavity. The single crystal furnace mechanism includes a single crystal furnace body, and the single crystal furnace body includes a top cover. The main body shell is fixedly disposed at the bottom end of the top cover, and the working cavity is fixedly disposed inside the main body shell.
[0006] A heat dissipation mechanism is fixedly installed on one side of the main body shell. The heat dissipation mechanism includes a water outlet pipe, a water outlet pump, a heat dissipation module, a water inlet pipe, and a water inlet pump. The heat dissipation mechanism includes a water outlet pipe, and the water outlet pipe includes a water outlet pump. A heat dissipation module is fixedly installed on one side of the water outlet pipe, and a water inlet pipe is fixedly installed at the bottom of one side of the heat dissipation module. The water inlet pipe includes a water inlet pump.
[0007] Preferably, a support rod is fixedly installed inside the working chamber, and a crucible tray is fixedly installed at the bottom end of the support rod. The advantage is that, after ensuring a safe distance between the crucible tray and the bolt cover, the tray can extend into the space between the bottom heater to increase the support rod travel space by 48mm. Through this 48mm space, the feeding amount can be increased by 20-30 kg, and this increase of 20-30 kg can increase the daily output by 2-3 kg, effectively improving the production.
[0008] Preferably, an electrode is fixedly installed inside the working chamber, and a heater is fixedly installed at the top of the electrode. The advantage is that by connecting the electrode to the heater, the temperature inside the working chamber can be continuously increased, which can effectively improve the temperature inside the working chamber during the production of monocrystalline silicon and effectively improve the practicality of the device.
[0009] Preferably, the heater and the electrode are fixed together by electrode fixing bolts, which has the advantage of ensuring the stability of the connection between the electrode and the heater.
[0010] Preferably, the inner wall of the working chamber is fixedly provided with a heat insulation layer. The advantage is that the heat insulation layer can effectively ensure the stability of the internal temperature of the working chamber and can effectively improve the efficiency when producing monocrystalline silicon.
[0011] Preferably, the top cover includes a baffle plate, which has the advantage of effectively blocking the heat flow inside the working chamber.
[0012] Preferably, a water-cooling cavity is fixedly installed inside the main body shell and connected to a heat dissipation module through an outlet pipe and an inlet pipe. The heat dissipation module includes a heat dissipation water pipe, a heat dissipation fan is fixedly installed at the top of the heat dissipation water pipe, and a coolant storage tank is fixed at the bottom of the heat dissipation water pipe. The advantage is that, in the past, single crystal furnaces often could not dissipate heat in time after use, resulting in excessive heat accumulation inside the single crystal furnace. Long-term use may reduce the service life of the single crystal furnace. Therefore, the heat dissipation mechanism can effectively cool down the single crystal furnace after use and increase the service life of the single crystal furnace.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This type of crucible holder with a release rod stroke is used by first opening the top cover to add material into the working chamber. During the material addition process, the rod retracts downward to increase the amount of material added. After the material addition is completed, the top cover is closed, and then the heater is connected through the electrode to continuously heat the inside of the working chamber. When the predetermined temperature is reached, the crucible holder can be pulled out. After the work is completed, coolant is drawn from the coolant storage tank through the water inlet pipe and water inlet pump and transported to the water-cooled chamber. After passing through the water-cooled chamber, the coolant is drawn out through the water outlet pipe and water outlet pump. When passing through the heat dissipation water pipe, the heat dissipation fan dissipates the coolant inside the heat dissipation water pipe, and then flows back into the coolant storage tank, where it is drawn back into the water inlet pipe and water inlet pump for circulation and heat dissipation. The advantage is that, in the previous single crystal furnace, The current type of crucible holder with a release rod stroke often fails to dissipate heat in time after use, leading to excessive heat accumulation inside the single crystal furnace. This can reduce the furnace's lifespan over time and result in insufficient material feeding, sometimes failing to meet the predetermined output. Therefore, a crucible holder with a release rod stroke is proposed. Firstly, after ensuring a safe distance between the crucible holder and the bolt cover, the tray can extend 48mm into the space between the bottom heaters, increasing the rod stroke space. This 48mm space allows for an increase in material feeding of 20-30 kg, which in turn increases daily output by 2-3 kg, effectively improving production. Furthermore, the circulating heat dissipation mechanism effectively extends the lifespan of the single crystal furnace. Attached Figure Description

[0025] In this embodiment, preferably, a support rod 9 is fixedly installed inside the working chamber 4, and a crucible tray 10 is fixedly installed at the bottom end of the support rod 9. After ensuring a safe distance between the crucible tray and the bolt cover, the tray can extend into the space between the bottom heater 12 to increase the travel space of the support rod 9 by 48mm. Through this 48mm space, the amount of material fed can be increased by 20-30 kg, and this increase of 20-30 kg can increase the daily output by 2-3 kg, effectively improving the production.
[0026] In this embodiment, preferably, an electrode 11 is fixedly disposed inside the working chamber 4, and a heater 12 is fixedly disposed at the top of the electrode 11. By connecting the electrode 11 to the heater 12, the working chamber 4 can be continuously heated, which can effectively improve the temperature inside the working chamber 4 during the production of monocrystalline silicon and effectively improve the practicality of the device.
[0027] In this embodiment, preferably, the heater 12 and the electrode 11 are fixed together by the electrode fixing bolt 13, which ensures the stability of the connection between the electrode 11 and the heater 12.
[0028] In this embodiment, preferably, a heat insulation layer 14 is fixedly provided on the inner wall of the working chamber 4. The heat insulation layer 14 can effectively ensure the stability of the internal temperature of the working chamber 4 and can effectively improve the efficiency when producing monocrystalline silicon.
[0029] In this embodiment, preferably, the top cover 2 includes a guide plate 15, which can effectively block the heat flow inside the working chamber 4.
[0030] In this embodiment, preferably, a water-cooling cavity 16 is fixedly installed inside the main body shell 3 and connected to a heat dissipation module 6 through a water outlet pipe 5 and a water inlet pipe 7. The heat dissipation module 6 includes a heat dissipation water pipe 17, a heat dissipation fan 18 is fixedly installed at the top of the heat dissipation water pipe 17, and a coolant storage tank 19 is fixed at the bottom of the heat dissipation water pipe 17. In the past, after use, single crystal furnaces often could not dissipate heat in time, resulting in excessive heat accumulation inside the single crystal furnace. Long-term use may reduce the service life of the single crystal furnace. Therefore, the heat dissipation mechanism can effectively cool down the single crystal furnace after use and increase the service life of the single crystal furnace.
[0031] In this embodiment, the crucible holder with a release rod stroke is used by first opening the top cover 2 to add material into the working chamber 4. During the material addition process, the rod 9 retracts downward to increase the amount of material added. After the material addition is completed, the top cover 2 is closed, and then the heater 12 is connected through the electrode 11 to continuously heat the inside of the working chamber 4.

After the work is completed, coolant is drawn from the coolant storage tank 19 through the water inlet pipe 7 and the water inlet pump 8 and transported to the water-cooled chamber 16. After passing through the water-cooled chamber 16, the coolant is drawn out through the water outlet pipe 5 and the water outlet pump 51. When passing through the heat dissipation water pipe 17, the cooling fan 18 cools the inside of the heat dissipation water pipe 17. The coolant is used for heat dissipation and then flows into the coolant storage tank 19. It is then drawn into the water inlet pipe 7 and the water inlet pump 8 for circulating heat dissipation. The advantage is that in the past, after use, heat dissipation was often not carried out in time, which led to excessive heat accumulation inside the single crystal furnace. Long-term use may reduce the service life of the single crystal furnace. In addition, the amount of material fed during the feeding process was small, and sometimes the predetermined output could not be achieved. Therefore, a crucible tray with a release rod stroke was proposed. First, after ensuring a safe distance between the crucible tray and the bolt cover, the tray can be inserted into the bottom heater 12 to increase the rod stroke space by 48mm. Through this 48mm space, the feeding amount can be increased by 20-30 kg, and this increase of 20-30 kg can increase the daily output by 2-3 kg, effectively improving the output. Moreover, the circulating heat dissipation through the heat dissipation mechanism can effectively improve the service life of the single crystal furnace.
