Description

Technical Field

[0001] This utility model relates to the field of ceramic crucible technology, and in particular to a ceramic crucible surface treatment device. Background Technology

[0002] Ceramic crucibles are a type of ceramic crucible, including silicon carbide graphite crucibles. Silicon carbide graphite crucibles are deep-bottomed, bowl-shaped ceramic containers with characteristics such as high bulk density, high temperature resistance, fast heat transfer, resistance to acid and alkali corrosion, high high-temperature strength, and high oxidation resistance. Ceramic crucibles require sandblasting treatment on their surface during production.

[0003] For example, patent publication number CN202420748833.5 discloses a ceramic crucible surface treatment device, including a hollow platform and a bottom cylinder. The beneficial effects are as follows: This utility model uses a hollow platform and an external silicone ring. When treating the outer surface of the ceramic crucible, the ceramic crucible can be inverted and placed on the top surface of the external silicone ring. The top opening of the ceramic crucible is inserted into the groove. Then, the air pump is started to extract the air from inside the hollow platform, which in turn extracts the air from inside the ceramic crucible through the air extraction hole, creating a negative pressure inside the ceramic crucible. This causes the top opening of the ceramic crucible to press tightly against the bottom surface of the groove, thus fixing the ceramic crucible. When treating the outer surface of the ceramic crucible, the bottom surface of the ceramic crucible can be placed on the top surface of the internal silicone pad. Similarly, the negative pressure can fix the ceramic crucible to the top surface of the internal silicone pad. This device can quickly fix the ceramic crucible by starting the air pump. The structure is very simple, the working efficiency is high, and it greatly facilitates the treatment of the inner and outer surfaces of the ceramic crucible by the workers.

[0004] However, while the above-mentioned device can adsorb and position the ceramic crucible during use, thereby improving the stability of its surface sandblasting treatment, in practical applications, it is not convenient to adjust the angle of the ceramic crucible. This makes it impossible to accurately control the uniformity and consistency of the sandblasting on the surface of the ceramic crucible during manual sandblasting, thus reducing the treatment quality of the ceramic crucible surface. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, the surface treatment device for ceramic crucibles is not convenient for adjusting the angle of the ceramic crucible, which in turn affects the uniformity and consistency of the surface sandblasting. Therefore, this invention proposes a surface treatment device for ceramic crucibles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ceramic crucible surface treatment device includes a base and a mounting base rotatably connected to the base. The base has a friction wheel that mates with the mounting base, and the friction wheel has a driving component. When the driving component operates, the mounting base rotates along the axis of the base. A vacuum pump is fixedly installed within the mounting base. The mounting base has a cavity communicating with the air inlet of the vacuum pump, and a through hole communicating with the cavity is also provided on the mounting base.

[0008] In order to drive the mounting base to adjust the angle of the ceramic crucible, preferably, the driving component includes a motor fixedly mounted on the base, and the output end of the motor is fixedly connected to the friction wheel.

[0009] To improve the stability of the mounting base rotation, preferably, a friction pad is fixedly sleeved on the mounting base, and the surface of the friction pad abuts against the surface of the friction wheel.

[0010] To increase friction and improve the rotational quality of the mounting base, the friction pad is further described as annular in shape and made of rubber.

[0011] To limit the position of the mounting base, preferably, the base has an annular groove, and a limiting ring that is fixedly connected to the mounting base is rotatably connected in the annular groove.

[0012] In order to limit the position of the ceramic crucible and improve its adsorption positioning stability, preferably, a limiting ring is fixedly installed on the mounting base, and the limiting ring has a groove.

[0013] To further protect the ceramic crucible, the limiting ring is made of rubber.

[0014] To facilitate the disassembly and cleaning of the ceramic crucible by staff, preferably, the mounting base is provided with an exhaust channel that communicates with the cavity, and the end of the exhaust channel away from the cavity is connected to a valve that is fixedly connected to the mounting base.

[0015] To facilitate heat dissipation of the air pump, preferably, the mounting base is provided with an air outlet groove, and the air outlet groove is located on one side of the motor.

[0016] To improve the adsorption and fixation efficiency of the ceramic crucible, preferably, the number of through holes is several, and they are arranged in a ring array along the axis of the mounting base.

[0017] Compared with the prior art, the present invention provides a ceramic crucible surface treatment device, which has the following beneficial effects:

[0018] 1. The ceramic crucible surface treatment device, through the exhaust channel and valve, after the ceramic crucible is sandblasted, opens the valve to allow external gas to enter the cavity. After the cavity returns to normal pressure, the negative pressure adsorption between the ceramic crucible and the mounting base is released, and the ceramic crucible can be easily removed.

[0019] 2. This ceramic crucible surface treatment device, through the setting of the driving component, when the motor drives the friction wheel to rotate, because the friction pad is in close contact with the friction wheel, the rotation of the friction wheel drives the mounting base to rotate through friction, thereby realizing the adjustment of the angle of the ceramic crucible. By dynamically adjusting the angle of the crucible, the uniformity and consistency of sandblasting can be significantly improved, ensuring the stability and reliability of the surface treatment quality of the ceramic crucible.

[0020] 3. The ceramic crucible surface treatment device, through the cooperation of the limiting ring and the groove, can limit the position of the ceramic crucible, thereby improving the stability of the ceramic crucible adsorption and fixation.

[0021] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model uses a vacuum pump to evacuate the internal cavity of the mounting base, creating a stable negative pressure environment between the ceramic crucible and the mounting base. This negative pressure adsorption mechanism enables the ceramic crucible to be quickly and reliably fixed. At the same time, the mounting base is rotated at a uniform speed by a drive component, which allows for precise control of the sandblasting angle of the ceramic crucible, thereby significantly improving the uniformity and processing quality of the sandblasting treatment on the surface of the ceramic crucible.

[0029] Example:

[0030] Reference Figures 1-4 A ceramic crucible surface treatment device includes a base 1 and a mounting base 2 rotatably connected to the base 1. The base 1 has an annular groove, and a limiting ring fixedly connected to the mounting base 2 is rotatably connected within the annular groove for limiting the position of the mounting base 2. The base 1 has a friction wheel 3 that cooperates with the mounting base 2. A friction pad 8 is fixedly sleeved on the mounting base 2. The surface of the friction pad 8 abuts against the surface of the friction wheel 3. When the friction wheel 3 rotates, the friction between the friction wheel 3 and the friction pad 8 drives the mounting base 2 to rotate. The friction pad 8 is annular in shape and made of rubber to improve the friction between the friction wheel 3 and the friction pad 8. The friction between the friction wheel 3 and the base 1 is driven by a drive component. When the drive component is working, the mounting base 2 rotates along the axis of the base 1 to adjust the angle of the ceramic crucible at a constant speed. The mounting base 2 is fixedly installed in the mounting base 2. The mounting base 2 is provided with a cavity 6 that is connected to the air inlet of the pump 5. The mounting base 2 is also provided with a through hole 7 that is connected to the cavity 6. The pump 5 draws air into the cavity 6 to make it negative pressure. The adsorption force of the negative pressure can fix the ceramic crucible on the top of the mounting base 2. There are several through holes 7, which are arranged in a ring along the axis of the mounting base 2 to improve the fixing efficiency of the ceramic crucible.

[0031] Specifically, the vacuum pump 5 is used to evacuate the cavity 6 inside the mounting base 2, so that a stable negative pressure environment is formed between the ceramic crucible and the mounting base 2. This negative pressure adsorption mechanism can achieve rapid and reliable fixation of the ceramic crucible. At the same time, the driving component drives the mounting base 2 to rotate at a uniform speed, which can achieve precise control of the sandblasting angle of the ceramic crucible, thereby significantly improving the uniformity and processing quality of the sandblasting treatment on the surface of the ceramic crucible.

[0032] The driving component includes a motor 4 fixedly mounted on the base 1, and the output end of the motor 4 is fixedly connected to the friction wheel 3.

[0033] Specifically, through the setting of the driving component, when the motor 4 drives the friction wheel 3 to rotate, since the friction pad 8 is in close contact with the friction wheel 3, the rotation of the friction wheel 3 drives the mounting base 2 to rotate through friction, thereby realizing the angle adjustment of the ceramic crucible. By dynamically adjusting the angle of the crucible, the uniformity and consistency of sandblasting can be significantly improved, ensuring the stability and reliability of the surface treatment quality of the ceramic crucible.

[0034] A limiting ring is fixedly installed on the mounting base 2, and a groove is provided on the limiting ring. The groove is designed to hold the ceramic crucible. The limiting ring is made of rubber to protect the ceramic crucible and prevent damage to the port of the ceramic crucible from friction.

[0035] Specifically, the combination of the limiting ring and the groove can limit the position of the ceramic crucible, thereby improving the stability of the ceramic crucible's adsorption and fixation.

[0036] The mounting base 2 is provided with an exhaust channel 9 that communicates with the cavity 6. The end of the exhaust channel 9 away from the cavity 6 is connected to a valve 10 that is fixedly connected to the mounting base 2. The valve 10 is threadedly connected to the mounting base 2 and communicates with the inner cavity of the exhaust channel 9.

[0037] Specifically, after the ceramic crucible is sandblasted, the valve 10 is opened to allow external gas to enter the cavity 6 through the exhaust channel 9 and the valve 10. After the cavity 6 returns to normal pressure, the negative pressure adsorption between the ceramic crucible and the mounting base 2 is released, and the ceramic crucible can be easily removed.

[0038] The mounting base 2 has twelve air outlet slots, which are located on one side of the motor 4.

[0039] Specifically, the air outlet groove facilitates heat dissipation for the air pump 5 inside the mounting base 2, thereby improving its service life.

[0040] Working principle: When positioning the ceramic crucible, the crucible is first inverted and placed in the groove of the limiting ring. Then, the vacuum pump 5 is started by the external control switch. The vacuum pump 5 performs a vacuum operation on the cavity 6, so that a stable negative pressure environment is formed between the ceramic crucible and the mounting base 2. This negative pressure adsorption mechanism can realize the rapid and reliable fixation of the crucible, ensuring that it remains stable in the subsequent processing.

[0041] During the sandblasting process, the motor 4 is started by an external control switch. The motor 4 drives the friction wheel 3 to rotate. Since the friction pad 8 is in close contact with the friction wheel 3, the rotation of the friction wheel 3 drives the mounting base 2 to rotate through friction, thereby realizing the angle adjustment of the ceramic crucible. By dynamically adjusting the angle of the crucible, the uniformity and consistency of sandblasting can be significantly improved, ensuring the stability and reliability of the surface treatment quality of the ceramic crucible.

[0042] After sandblasting is completed, first turn off motor 4, then manually open valve 10. External gas enters cavity 6 through valve 10, restoring the internal pressure to normal. At this time, the negative pressure adsorption between the ceramic crucible and the mounting base 2 is released, and the crucible can be easily removed, completing the disassembly process.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
