Description

Technical Field

[0001] This utility model relates to the field of crucible equipment technology, specifically to an automatic feeding quartz ceramic crucible. Background Technology

[0002] Currently, quartz ceramic crucibles are used in high-temperature smelting and industrial production, particularly in metallurgy, chemical engineering, and electronics. Many traditional feeding methods still rely on manual operation or semi-automated equipment, which presents certain risks and shortcomings. In high-temperature environments, manual feeding is not only prone to errors but can also affect safety and production efficiency due to prolonged exposure of personnel to high temperatures. Furthermore, manual operation in high-temperature environments makes it impossible to precisely control the feeding amount and speed, thus hindering the stability and continuity of the production process. Utility Model Content

[0003] In view of the shortcomings of the prior art and to solve the problems mentioned in the background art, the technical problem to be solved by this utility model is to provide an automatic feeding quartz ceramic crucible that can accurately control the feeding amount and feeding speed.

[0004] The technical problem to be solved by this utility model is achieved through the following technical solution: an automatically feeding quartz ceramic crucible, including a crucible melter, with several rotatable crucible feeding assemblies above the melter. Each crucible feeding assembly includes a rotating frame, a rotating shaft at the bottom of the frame, and a drive mechanism at the lower part of the shaft to drive the frame to rotate horizontally. Several feeding crucibles are arranged circumferentially along the rotating shaft on the frame, each containing silicon material. The feeding crucibles rotate synchronously with the frame, and the frame drives each crucible to rotate to a position directly opposite the melter. A quick-connect fitting is provided between the crucible discharge port and the top discharge port of the melter, and a discharge valve is also provided at the discharge port. The drive mechanism drives the synchronous rotation of the frame and the crucibles, ensuring that each crucible is precisely positioned opposite the melter, ensuring the accuracy and stability of the feeding. This automated feeding system avoids manual operation of high-temperature equipment, improving the feeding efficiency and production safety of the production line. Each feeding crucible is equipped with a feeding valve and quick-connect fitting at the bottom, which precisely controls the feeding amount of each crucible, and the feeding valve ensures the stability and continuity of feeding.

[0005] As a further embodiment of this invention, the quick-connect component includes a first flange located at the feed inlet of the feeding crucible and a second flange located at the feed inlet of the crucible feeder. The first and second flanges are paired together. A double sealing ring is provided on the sealing surface of the second flange. Pre-tightening components are evenly distributed around the outer edge of the second flange along its central axis. Each pre-tightening component includes a support rod, with a pressure rod hinged to the free end of the support rod. A damping ring is provided in the hinge hole between the support rod and the pressure rod. A clamping groove is provided on the back of the first flange to mate with the end of the pressure rod. The double sealing rings provide a reliable seal, preventing material leakage during feeding and ensuring safety and stability during production. The damping ring increases the resistance at the hinge point, creating resistance between the support rod and the pressure rod during rotation. The pressure rod generates friction with the clamping groove, clamping the first and second flanges together, resulting in good sealing performance.

[0006] As a further embodiment of this invention, a feeding pipe is provided between the first flange and the feeding crucible's discharge port, and a feeding valve is installed on the feeding pipe. The feeding valve is an electric valve. The electric valve automatically starts and stops, quantitatively adding silicon material from the feeding crucible into the crucible material feeder, ensuring precise and efficient feeding.

[0007] As a further embodiment of this utility model, the driving mechanism is a rotary motor with the rotary motor shaft vertically upward. A device bracket is provided on one side of the rotary motor. The device bracket includes two vertically arranged support columns, and a mounting plate is provided between the support columns. The rotary motor body is fixed to the mounting plate by bolts. A reinforcing column is provided at the bottom of the rotary motor. A rotating shaft is provided on the rotary motor shaft, and the rotating shaft is fixedly set with the rotating frame.

[0008] As a further embodiment of this invention, the rotating frame includes several horizontal rotating arms arranged circumferentially along the rotation axis. A triangular bracket is provided between the horizontal rotating arms and the rotation axis, providing support and stability, and reinforcing the horizontal cantilever arms. A device mounting ring is provided at the free end of each horizontal rotating arm. A limiting reinforcing rib is provided on the outer wall of the feeding crucible, with the lower ring surface of the limiting reinforcing rib contacting and supporting the upper ring surface of the mounting ring. The feeding crucible is installed in the mounting ring. The limiting reinforcing ribs cooperate to stably support the feeding crucible.

[0009] As a further embodiment of this invention, a controller is also provided on the other side of the mounting plate. The controller is communicatively connected to the rotary motor and the feeding valve. The controller has a preset program that controls the rotation angle of the rotary motor, drives the rotating frame to rotate, and causes the first flange and the second flange to precisely engage. The controller also controls the opening and closing of the feeding valve. The controller achieves automatic control, eliminating the need for manual operation and enabling safe and efficient production.

[0010] As a further embodiment of this invention, a main furnace crucible is located below the crucible melter. A feed inlet is located at the top of the main furnace crucible, corresponding to the discharge port at the bottom of the crucible melter. A shut-off valve is provided between the main furnace crucible and the crucible melter. A reinforcing ring is provided on the outer wall of the main furnace crucible. A main furnace frame is located at the bottom of the main furnace crucible, with a mounting surface and mounting holes on the mounting surface. The main furnace crucible is installed in the mounting holes. Several support legs are located at the bottom of the mounting surface, and a reinforcing support column at the bottom of the rotary motor is mounted on the mounting surface. The coordination between the feed inlet and the discharge port of the crucible melter ensures accurate and smooth feeding. The reinforcing ring on the outer wall of the main furnace crucible strengthens the crucible and disperses stress.

[0011] As a further embodiment of this invention, a heating element is fitted externally to the crucible feeder. This heating element is a resistance heating device, and an insulation layer is wrapped around it. The heating element helps to precisely control the temperature inside the crucible, improving temperature stability and uniformity. The insulation layer effectively prevents heat loss, reduces heat radiation from the surrounding environment, avoids overheating damage to operators or surrounding equipment, and enhances the safety of the working environment.

Each crucible feeding assembly includes a rotating frame with a rotating shaft at its bottom. A drive mechanism is located below the rotating shaft to drive the rotating frame to rotate horizontally. Several feeding crucibles are arranged circumferentially along the rotating shaft on the rotating frame, each containing silicon material. The feeding crucibles rotate synchronously with the rotating frame, causing each feeding crucible to rotate to a position directly opposite the melter. A quick-connect fitting is provided between the feeding crucible outlet and the top feeding port of the melter, and a feeding valve is also provided at the feeding crucible outlet. The drive mechanism drives the synchronous rotation of the rotating frame and the feeding crucibles, ensuring that each feeding crucible is accurately positioned directly opposite the melter, ensuring the accuracy and stability of feeding. Through the automated feeding system, manual operation of high-temperature equipment is avoided, improving the feeding efficiency and production safety of the production line.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The serial numbers assigned to components in this document, such as "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application...

[0020] Unless otherwise specified, "connection" includes both direct and indirect connections. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature means that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature means that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0022] As shown in Figures 1-4, an automatically feeding quartz ceramic crucible includes a crucible melter 9. A heating element, a resistance heating device, is externally mounted on the melter and is further encased in a heat insulation layer. The resistance heating device generates heat when energized, and this heat is transferred through the melter wall into the crucible container. The heat insulation layer prevents heat loss to the outside and effectively reduces the impact of high temperatures on the production environment. The melter is supported by a central support platform, reducing the stress on the melter.

[0023] Above the crucible feeder are several rotatable crucible feeding assemblies 5. Each crucible feeding assembly includes a rotating frame with a rotating shaft 503 at the bottom. A drive mechanism 501 for driving the rotating frame to rotate horizontally is located at the bottom of the rotating shaft. Several feeding crucibles 6 are arranged around the rotating shaft on the rotating frame. Each feeding crucible is loaded with silicon material. Each feeding crucible has a feeding port at the top. When each feeding crucible rotates to a set position, the silicon material from the previous process automatically falls into the feeding crucible until the feeding crucible is full, at which point the feeding of the feeding crucible is stopped.

[0024] The feeding crucible rotates synchronously with the rotating frame. The rotating frame drives each feeding crucible to rotate until it is directly opposite the crucible melter. The rotating frame includes several horizontal rotating arms 504 arranged circumferentially along the rotation axis. A triangular bracket 502 is provided between the horizontal rotating arms and the rotation axis, and the triangular bracket supports the horizontal rotating arms. An equipment mounting ring 505 is provided at the free end of each horizontal rotating arm. A limiting reinforcing rib 601 is provided on the outer wall of the feeding crucible. The lower ring surface of the limiting reinforcing rib contacts and supports the upper ring surface of the mounting ring. The feeding crucible is installed in the mounting ring. During equipment installation, the feeding crucible is installed in the mounting ring, and the limiting reinforcing rib cooperates with the mounting ring for installation support.

[0025] A quick-connector 8 is provided between the feeding port of the feeding crucible and the feeding port at the top of the crucible melter. The quick-connector includes a first flange 801 located at the feeding port of the feeding crucible and a second flange 802 located at the feeding port of the crucible melter. The first flange and the second flange are paired. A double sealing ring 806 is provided on the sealing surface of the second flange. Pre-tightening elements are evenly distributed around the outer edge of the second flange along the central axis. The pre-tightening elements include a support rod 805. A pressure rod 803 is hinged to the free end of the support rod. A damping ring 804 is provided in the hinge hole between the support rod and the pressure rod. A clamping groove that mates with the end of the pressure rod is provided on the back of the first flange.

[0026] When the feeding crucible rotates to directly above the crucible material feeder, the first flange mates with the second flange. After the first and second flanges are aligned, the operator manually uses a long guide rod to rotate and push the pressure rod to the position where it mates with the clamping groove, thus clamping the first and second flanges together. A double sealing ring then seals the area, ensuring that the silicon material does not overflow during the feeding process.

[0027] A discharge valve 7 is also provided at the discharge port of the feeding crucible. A discharge pipe is provided between the first flange and the discharge port of the feeding crucible, and the discharge valve is installed on the discharge pipe. The discharge valve is an electric valve. The controller controls the opening and closing of the discharge valve.

[0028] After the first flange and the second flange are sealed and connected, the controller 4 controls the feeding valve to open, and the silicon material in the feeding crucible is added to the crucible material feeder. When the amount added reaches the standard, the feeding valve is closed and the feeding stops.

[0029] Once the silicon material feeding in one of the feeding crucibles is complete, the discharge valve is closed, and the pressure rod is manually rotated and pulled away from the clamping groove using a long guide rod. The first and second flanges are then in a free state.

[0030] The lower part of the rotating frame is equipped with a drive mechanism 501 for driving the rotating frame to rotate horizontally. The drive mechanism is a rotary motor with the rotary motor shaft set vertically upward. A device bracket 2 is provided on one side of the rotary motor. The device bracket includes two vertically set support columns 201. A mounting plate 202 is provided between the support columns. The rotary motor body is fixed to the mounting plate by bolts. A reinforcing column 3 is provided at the bottom of the rotary motor. A rotating shaft is provided on the rotary motor shaft and is fixedly set to the rotating frame.

[0031] In industrial production, different silicon materials need to be added to the crucible material feeder. A controller is also located on the other side of the mounting plate. Controller 4 is communicatively connected to the rotary motor and the feeding valve. The controller has a preset program that controls the rotation angle of the rotary motor, driving the rotating frame to rotate and precisely engage the first flange 801 and the second flange 802. The controller starts the rotary motor, driving the rotating frame to rotate and rotate the first feeding crucible directly above the crucible material feeder. The first and second flanges are then paired. After alignment, a long guide rod is manually used to rotate and push the pressure rod to the position that mates with the clamping groove, clamping the first and second flanges. A double sealing ring is then used for sealing, ensuring that the silicon material does not overflow during the feeding process.

[0032] A discharge valve 7 is also provided at the discharge port of the feeding crucible. A discharge pipe is provided between the first flange and the discharge port of the feeding crucible, and the discharge valve is installed on the discharge pipe. The discharge valve 7 is an electric valve. The controller controls the opening and closing of the discharge valve.

[0033] After the first flange and the second flange are sealed and connected, the controller controls the feeding valve to open, and the silicon material in the feeding crucible is added into the crucible material feeder 9. When the amount added reaches the standard, the feeding valve 7 is closed and the feeding stops.

[0034] Once the silicon material feeding in one of the feeding crucibles is complete, the discharge valve is closed, and the pressure rod is manually rotated and pulled away from the clamping groove using a long guide rod. The first and second flanges are then in a free state.

[0035] When the silicon material reaches the set amount in the crucible melter, the resistance heating device is energized to generate heat. The heat is transferred through the wall of the crucible melter to the inside of the crucible melter, where the temperature reaches 500℃-1500℃, causing the silicon material to melt and form a liquid state.

[0036] The crucible melter is located below the main furnace crucible 1. The top of the main furnace crucible is provided with a feeding inlet, which corresponds to the discharge port at the bottom of the crucible melter. A shut-off valve 10 is provided between the main furnace crucible and the crucible melter. When the shut-off valve is opened, the high-temperature molten silicon material formed in the crucible melter flows into the main furnace crucible for secondary melting.

[0037] The outer wall of the main furnace crucible is provided with a reinforcing ring, and the bottom of the main furnace crucible is provided with a main furnace frame 101. The main furnace frame is provided with a mounting surface, and the mounting surface is provided with mounting holes. The main furnace crucible is installed in the mounting holes. Several support legs are provided at the bottom of the mounting surface, and the reinforcing support column at the bottom of the rotary motor is provided on the mounting surface.

[0038] The silicon material that is molten a second time in the main furnace crucible is discharged through the outlet at the bottom of the main furnace crucible.

[0039] In this specification, the terms "connection," "installation," "fixing," and "setting" are interpreted broadly. For example, "connection" can mean a fixed connection or an indirect connection via intermediate components without affecting the relationship between components or the technical effect; it can also mean an integral connection or a partial connection. Those skilled in the art can understand the specific meaning of these terms in this utility model or utility model based on the specific circumstances. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
