Description

Technical Field

[0001] This utility model relates to the field of water-cooled screen technology, and more specifically, to an adjustable water-cooled screen mechanism. Background Technology

[0002] In the process of preparing single crystal silicon using the Czochralski method, the crystal rod needs to be cooled as it moves upward to fix and shape the crystal rod, thereby producing a single crystal silicon rod. The water-cooled screen, also known as the water-cooled heat shield, is an important component of the single crystal furnace. This device is located inside the single crystal furnace and is filled with circulating cooling water. The cooling water removes the latent heat of crystallization of the crystal rod, accelerates the crystal growth rate, increases equipment capacity, reduces energy consumption, and reduces production costs.

[0003] Existing water-cooled screens use a spiral flow channel, where coolant flows inside the spiral flow channel to exchange heat with the crystal rod located in the middle of the tank. However, the filling height of the spiral flow channel in existing water-cooled screens is fixed and cannot be adjusted according to the height of the crystal rod. When the crystal growth height increases, the coolant at the fixed height can only cover the lower part of the crystal, and the upper part lacks effective cooling, resulting in excessively high temperature at the top of the crystal, which affects the crystal growth quality. Therefore, an adjustable water-cooled screen mechanism is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable water-cooled screen mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable water-cooled screen mechanism, including a barrel body, a spiral plate fixedly connected to the middle of the barrel body wall, which forms a spiral flow channel in the middle cavity of the barrel body wall, prolonging the residence time of cooling water and improving heat exchange efficiency; multiple first heat-conducting strips fixedly connected to the inner wall of the barrel body; multiple second heat-conducting strips fixedly connected to the inner side of the middle of the barrel body wall; through the cooperation of the first and second heat-conducting strips with the inner wall of the barrel body, heat exchange efficiency can be improved while cooling efficiency is improved; a water inlet pipe fixedly connected to one side of the barrel body, through which coolant can be input into the bottom of the middle cavity of the barrel body wall; and a stabilizing riser fixedly connected to the other side of the barrel body.

[0006] A water outlet pipe is fixedly connected to the top of one side of the stabilizing riser, and a fixed-distance electric push rod is fixedly connected to the top of the stabilizing riser. The output end of the fixed-distance electric push rod extends into the interior of the stabilizing riser and is fixedly connected to a lifting block. A groove is formed on the top of the lifting block, and a through hole is formed on one side of the bottom of the inner cavity of the groove. Multiple water outlet holes are formed on the side of the inner cavity of the stabilizing riser. By aligning the water outlet holes with the through holes, the liquid in the cavity of the tank wall can be raised to the height of the through hole and then enter the groove through the corresponding water outlet hole and through hole, and then sequentially enter the interior of the water outlet pipe for discharge. Activating the fixed-distance electric push rod controls the movement of the lifting block, which can adjust the alignment of the through hole with water outlet holes of different heights. At this time, the height of the liquid in the cavity of the tank wall can be adjusted, thereby adjusting the heat exchange and cooling area size for convenient adjustment and use.

[0007] Preferably, the first heat-conducting strip and the second heat-conducting strip correspond one-to-one, the spiral plate passes through the middle of the second heat-conducting strip, and the bottom end of the water inlet pipe is connected to the bottom end of the cavity in the middle of the barrel wall. The heat exchange efficiency of the coolant in the cavity of the barrel wall can be improved through the first heat-conducting strip and the second heat-conducting strip, and the coolant can be conveniently injected into the bottom of the cavity of the barrel wall through the water inlet pipe.

[0008] Preferably, the water outlet and the spiral plate are offset from each other, the water outlet is located at the top of one side of the barrel, and the inner cavity of the stabilizing riser is connected to the wall cavity of the barrel through the water outlet. By discharging liquid through water outlets at different heights, the coolant height in the barrel wall cavity can be different.

[0009] Preferably, the wall of the lifting block is tightly fitted with the inner wall of the stabilizing riser, and a sealing gasket is provided on the outer surface wall of the lifting block. The height of the discharged liquid can be adjusted by lifting the lifting block, and the sealing effect is improved by the sealing gasket.

[0010] Preferably, the through hole corresponds to one of the water outlet holes, and the opening on one side of the groove corresponds to the position of the water outlet pipe. The liquid in the cavity of the barrel wall can be input into the top of the lifting block inside the stable riser through the water outlet hole and the through hole, so as to facilitate discharge.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model firstly uses a spiral plate to form a spiral flow channel in the middle cavity of the barrel wall, which prolongs the residence time of cooling water and improves heat exchange efficiency. By activating the fixed-distance electric push rod to control the movement of the lifting block, the through hole can be adjusted to correspond with the water outlet at different heights. At this time, the height of the liquid in the cavity of the barrel wall can be adjusted, thereby adjusting the size of the heat exchange and cooling area, which is convenient for adjustment and use.

[0013] 2. This utility model also improves the heat exchange and cooling efficiency by cooperating with the inner wall of the barrel through the first and second heat-conducting strips, and improves the sealing strength between the lifting block and the stabilizing riser by the sealing gasket set in the wall of the lifting block, thereby improving the adjustment effect.

[0021] 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.

[0022] As attached Figure 1-5An adjustable water-cooled screen mechanism is shown, including a barrel 1. A spiral plate 2 is fixedly connected to the middle of the wall of the barrel 1. The spiral plate 2 can form a spiral flow channel in the cavity in the middle of the wall of the barrel 1, prolonging the residence time of the cooling water and improving the heat exchange efficiency. Multiple first heat-conducting strips 3 are fixedly connected to the inner wall of the barrel 1. Multiple second heat-conducting strips 4 are fixedly connected to the inner side of the middle of the wall of the barrel 1. Through the cooperation of the first heat-conducting strips 3 and the second heat-conducting strips 4 with the inner wall of the barrel 1, the heat exchange efficiency can be improved while the cooling efficiency is improved. A water inlet pipe 5 is fixedly connected to one side of the barrel 1. Coolant can be input into the bottom of the cavity in the middle of the wall of the barrel 1 through the water inlet pipe 5. A stabilizing riser 6 is fixedly connected to the other side of the barrel 1.

[0023] A water outlet pipe 7 is fixedly connected to the top of one side of the stable riser 6. A fixed-distance electric push rod 9 is fixedly connected to the top of the stable riser 6. The output end of the fixed-distance electric push rod 9 extends into the interior of the stable riser 6 and is fixedly connected to a lifting block 10. A groove 11 is opened on the top of the lifting block 10. A through hole 12 is opened on one side of the bottom of the inner cavity of the groove 11. Multiple water outlet holes 8 are opened on the side of the inner cavity of the stable riser 6. By the correspondence between the water outlet holes 8 and the through holes 12, the liquid in the cavity of the tank 1 wall can be raised to the height of the through hole 12. Then, it enters the groove 11 through the corresponding water outlet holes 8 and the through holes 12, and then enters the interior of the water outlet pipe 7 for discharge. Activating the fixed-distance electric push rod 9 controls the movement of the lifting block 10, which can adjust the correspondence between the through hole 12 and the water outlet holes 8 at different heights. At this time, the height of the liquid in the cavity of the tank 1 wall can be adjusted, thereby adjusting the heat exchange and cooling area size for convenient adjustment and use.

[0024] As attached Figure 1-5 As shown, the first heat-conducting strip 3 and the second heat-conducting strip 4 correspond one-to-one. The spiral plate 2 passes through the middle of the second heat-conducting strip 4. The bottom end of the water inlet pipe 5 is connected to the bottom end of the cavity in the middle of the wall of the barrel 1. The water outlet 8 is offset from the spiral plate 2 and is located at the top of one side of the barrel 1. The inner cavity of the stabilizing riser 6 is connected to the cavity of the wall of the barrel 1 through the water outlet 8. The wall of the lifting block 10 is tightly fitted with the inner wall of the stabilizing riser 6. A sealing gasket is provided on the outer surface wall of the lifting block 10. The through hole 12 corresponds to one of the water outlets 8. One side of the groove 11 is open. Corresponding to the position of the outlet pipe 7, the first heat-conducting strip 3 and the second heat-conducting strip 4 can improve the heat exchange efficiency of the coolant in the cavity of the barrel 1 wall. The inlet pipe 5 facilitates the injection of coolant into the bottom of the cavity of the barrel 1 wall. The coolant height in the cavity of the barrel 1 wall can be different by discharging liquid through the outlet holes 8 at different heights. The height of the discharged liquid can be adjusted by raising and lowering the lifting block 10, and the sealing effect is improved by the sealing gasket. The liquid in the cavity of the barrel 1 wall can be fed into the top of the lifting block 10 inside the stable riser 6 through the outlet hole 8 and the through hole 12, which is convenient for discharge.

[0025] The working principle of this utility model is as follows: When in use, the water-cooled screen is installed in the single crystal silicon growth furnace. Cooling liquid is introduced into the bottom of the wall cavity of the barrel 1 through the water inlet pipe 5. The liquid moves upward in the wall cavity of the barrel 1 through the guide spiral of the spiral plate 2 until it enters the interior of the groove 11 through the water outlet 8 corresponding to the through hole 12, and then is discharged into the interior of the water outlet pipe 7 through the guide spiral of the stabilizing riser 6.

[0026] The coolant is cooled by heat exchange with the lifting crystal located in the middle of the barrel 1 through the first heat-conducting strip 3 and the second heat-conducting strip 4.

[0027] During use, the lifting block 10 can be moved inside the stable riser 6 by activating the fixed-distance electric push rod 9. The water outlet 8 of the through hole 12 can be adjusted to the corresponding height, so that the liquid height in the cavity of the tank 1 wall can be adjusted accordingly. Therefore, it is convenient to adapt to the cooling needs of different heights and improve the use effect.
