Description

Technical Field

[0001] This utility model relates to the field of silicon material cleaning and purification technology, and in particular to a cleaning device that can quickly load and unload silicon material. Background Technology

[0002] Silicon material manufacturers use a cleaning device in the fine washing stage of the purification process. Because the cleaning fluid used is highly corrosive, the device must be corrosion-resistant, well-sealed, and able to withstand low pressure. However, loading and unloading of materials is an essential step, requiring the cleaning device to have openings and covers to fulfill this function. Most companies, in developing this device, to reduce leakage and contamination while ensuring cleaning purity and impurity removal, only install a small manhole. This manhole is used not only for observation before and after operation but also for loading and unloading materials. Typically, a 1-ton cleaning unit requires manually handling 50 barrels of silicon material (20 kg / barrel) to complete the loading, resulting in high labor intensity and low efficiency. Furthermore, unloading through the manhole after cleaning is also time-consuming and labor-intensive. Moreover, due to the small opening, this type of device can only be treated with a general anti-corrosion coating, which has limited thickness. If any part of the anti-corrosion coating peels off, repair is difficult. Therefore, the current equipment has shortcomings and hidden dangers such as high manual labor intensity, low efficiency, short service life of anti-corrosion layer and difficulty in repair, which urgently need to be solved. Utility Model Content

[0003] The technical problem this utility model aims to solve is to overcome the shortcomings of existing technologies by proposing a cleaning device that can quickly load and unload silicon material, thereby solving the problems of high manual labor intensity, low efficiency, short service life of anti-corrosion layer and difficulty in repair in current equipment.

[0004] To solve the above technical problems, the technical solution of this utility model is as follows:

[0005] A cleaning device for rapid loading and unloading of silicon material includes a frame, a lifting assembly at the top of the frame, a rotary power assembly in the middle of the frame, a bearing assembly, and a vessel body. The vessel body has an upper cover and a lower cover respectively. The lifting assembly is connected to the upper cover via a lifting rod, controlling the upper cover's up-and-down movement to open and close the vessel body. The rotary power assembly passes through the bearing assembly to control the vessel body to rotate at a fixed angle. The top of the upper cover has a vent, a liquid inlet assembly 1, a liquid inlet assembly 2, a temperature detection port, and a pressure detection port. The bottom of the lower cover has an air inlet assembly and a liquid drain assembly. Fluororubber gaskets 1, 2, and 3 are respectively installed between the manhole cover and the upper cover, the upper cover and the vessel body, and the lower cover and the vessel body to ensure the vessel body is sealed and leak-free.

[0006] Furthermore, the lifting assembly consists of a servo motor and a reducer connected to four sets of lifting mechanisms via a coupling and a transmission shaft. The lifting assembly is connected to the upper cover via four lifting rods, controlling the upper cover to open and close smoothly and quickly. Six pull-button assemblies are evenly arranged around the circumference of the vessel body and the upper cover. A fluororubber gasket is placed between the vessel body and the upper cover. These double connection and sealing measures ensure reliable connection and no leakage.

[0007] Furthermore, the top cover is equipped with liquid inlet component 1 and liquid inlet component 2, which can realize the injection and proportion adjustment of different cleaning liquids. The vent interface is connected to the workshop waste recycling system to avoid the pollution of the environment by the exhaust gas generated by the chemical reaction. Temperature detection port and pressure detection port are respectively equipped with corresponding sensors to monitor the internal temperature and pressure of the vessel in real time. A manhole cover is provided at the front of the top cover for easy observation of the operation before and after cleaning. A fluororubber gasket is provided between the manhole cover and the top cover, and the connection is reliable and leak-free through 8 locking components set around the perimeter.

[0008] Furthermore, the rotary power component is connected to the rotating shaft on the vessel body and drives the vessel body to rotate at a fixed angle through the bearing assembly. After the cleaning operation is completed and the top cover is opened to a fixed height, the vessel body is driven to rotate 120° to facilitate the rapid unloading of silicon material. After unloading and cleaning, the vessel body is reversed to 80° so that the next batch of silicon material to be cleaned can be loaded quickly. After loading, the vessel body is rotated back to 0° and the top cover is closed under the transmission of the lifting component, thus completing a complete silicon material loading and unloading operation process.

[0009] Furthermore, the inside of the vessel body is provided with an anti-corrosion layer, which can prevent the cleaning liquid and silicon material from corroding and scratching the vessel body. The bottom of the vessel body is provided with a perforated plate and filter cloth, which serve to support the silicon material and filter it. A fluororubber gasket is provided between the vessel body and the lower cover, and a sealed connection is achieved by a group of bolts evenly arranged around the circumference.

[0010] Furthermore, an air intake component is provided at the bottom of the lower cover. During the cleaning process, compressed air enters the interior through the air intake component and forms a certain air pressure between the filter cloth to promote the internal cleaning liquid to surge, thereby driving the silicon material to roll and improve the cleaning effect. The drain component at the bottom is used to pump out the waste liquid after cleaning.

[0011] Furthermore, the control cabinet is located on the bottom right side of the frame and is the human-machine operation control part for the sensor monitoring and lifting components and the rotation power components.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This utility model discloses a silicon material cleaning device with rapid loading and unloading capabilities. A large opening with the same diameter as the vessel body is provided at the top of the vessel, with an area five times larger than the original. This opening divides the container into two parts. The top cover can be quickly opened and closed using a lifting component on the frame, while the vessel body can be rotated at a fixed angle using a rotary power mechanism, thus enabling rapid loading and unloading. Furthermore, the corrosion-resistant part of the vessel body is changed from a sprayed anti-corrosion layer to an inner lining anti-corrosion layer, with a thickness three times that of the original, significantly extending its service life. Moreover, if the anti-corrosion layer is partially damaged or worn, it can be quickly repaired through the large opening, reducing maintenance costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] Figures 1 to 5 As shown, a cleaning device for quickly loading and unloading silicon material includes a frame 2, a lifting assembly 1 at the top of the frame 2, a rotary power assembly 10 in the middle of the frame 2, a bearing assembly 11, and a vessel body 7. The vessel body 7 has an upper cover 3 and a lower cover 8 respectively at its upper and lower parts. The lifting assembly 1 is connected to the upper cover 3 via a lifting rod 106, controlling the upper cover 3 to move up and down to open and close the vessel body 7. The rotary power assembly 10 passes through the bearing assembly 11 to control the vessel body 7 to rotate at a fixed angle. The top of the upper cover 3 is provided with a vent 301, a liquid inlet 1 assembly 302, a liquid inlet 2 assembly 303, a temperature detection port 304, and a pressure detection port 305. The bottom of the lower cover 8 is provided with an air inlet assembly 802 and a liquid drain assembly 803. Fluororubber gaskets 401, 306, and 801 are respectively installed between the manhole cover 4 and the upper cover 3, between the upper cover 3 and the vessel body 7, and between the lower cover 8 and the vessel body 7 to ensure the vessel body 7 is sealed and leak-free.

[0023] The lifting assembly 1 is composed of a servo motor 101, a reducer 102, and four sets of lifting mechanisms 104 connected by a coupling 103 and a drive shaft 105. The lifting assembly 1 is connected to the upper cover 3 by four lifting rods 106, which control the upper cover 3 to open and close smoothly and quickly. Six pull buckle assemblies 6 are evenly arranged around the circumference of the vessel body 7 and the upper cover 3. A fluororubber gasket 306 is placed between the vessel body 7 and the upper cover 3. The double connection and sealing measures ensure reliable connection and no leakage.

[0024] The top cover 3 is equipped with liquid inlet component 1 302 and liquid inlet component 2 303, which can realize the injection and proportion adjustment of different cleaning liquids. The vent interface 301 is connected to the workshop waste recycling system to avoid the pollution of the environment by the waste gas generated by the chemical reaction. Temperature detection port 304 and pressure detection port 305 are respectively equipped with corresponding sensors to monitor the internal temperature and pressure of the vessel body 7 in real time. A manhole cover 4 is provided at the front of the top cover 3 to facilitate the observation of the operation before and after cleaning. A fluororubber gasket 401 is provided between the manhole cover 4 and the top cover 3. The connection is reliable and leak-free through 8 locking components 5 set around the perimeter.

[0025] The rotary power assembly 10 is connected to the rotating shaft 704 on the vessel body 7 and drives the vessel body 7 to rotate at a fixed angle through the bearing assembly 11. After the cleaning operation is completed, the top cover 3 is opened to a fixed height and the vessel body 7 is driven to rotate 120°, which can facilitate the quick unloading of silicon material. After unloading and cleaning, the top cover 3 is reversed to 80°, and the next batch of silicon material to be cleaned can be loaded quickly. After loading, the top cover 3 is rotated back to 0° and closed under the transmission of the lifting assembly 1. A complete silicon material loading and unloading operation process is completed.

[0026] The vessel body 7 is equipped with an anti-corrosion layer 701, which can prevent the cleaning liquid and silicon material from corroding and scratching the vessel body 7. The bottom of the vessel body 7 is equipped with a perforated plate 703 and a filter cloth 702, which serve to support the silicon material and filter it. A fluororubber gasket 801 is installed between the vessel body 7 and the lower cover, and a sealed connection is achieved by a group of bolts evenly arranged around the circumference.

[0027] The bottom of the lower cover 8 is equipped with an air intake component 802. During the cleaning process, compressed air enters the interior through the air intake component 802 and forms a certain air pressure between it and the filter cloth 702 to promote the internal cleaning fluid to surge, thereby driving the silicon material to roll and improve the cleaning effect. The drain component 803 at the bottom is used to pump out the waste liquid after the cleaning is completed.

[0028] The control cabinet 9 is located on the bottom right side of the frame 2 and is the human-machine operation control part of the sensor monitoring and lifting assembly 1 and the rotation power assembly 10.

[0029] In the specific implementation of this utility model:

[0030] At the start of cleaning, manually open the six evenly spaced latch components 6 around the opening of the vessel body 7. Then, operate the lifting component 1 on the upper part of the frame 2 from the control cabinet 9 to raise the top cover 3 to a fixed position. Next, control the rotation power component 10 to drive the vessel body 7 to rotate to 80° for loading. After loading is complete, the vessel body 7 reverses back to 0°, and the lifting component 1 lowers the top cover 3 to the closed position. Then, manually close the six latch components 6. Start the bottom air intake component 802 to inject compressed air to a certain pressure and maintain the pressure for 10 minutes without leakage. Open the top vent 301 to exhaust air until the pressure is close to atmospheric pressure. After injecting an appropriate amount of cleaning fluid into the inlet liquid 1 component 302 and the inlet liquid 2 component 303, the cleaning operation is carried out. At the same time, the air inlet component 802 is opened again to maintain a certain pressure at the bottom, which promotes the flow of cleaning fluid and causes the silicon material to roll. After a certain period of cleaning, the cleaning operation is completed. The drain component 803 is opened to drain the cleaning fluid. After the cleaning fluid is drained, the 6 locking components 6 are manually opened, and the top cover 3 is raised to the fixed position. Then, the rotation power component 10 is controlled to drive the vessel body 7 to rotate 120° to unload the silicon material. After the silicon material is unloaded and the vessel body 7 is cleaned, it is rotated back 80° to carry out the second round of silicon material loading operation. This cycle is repeated.

[0031] The purpose of this invention is to increase the opening area to facilitate rapid loading and unloading of silicon material through hoisting and other methods, reduce the intensity of work, and improve cleaning efficiency. At the same time, the large opening area allows the process of the internal anti-corrosion layer of the reactor body to be changed to an inner lining process, increasing the thickness of the anti-corrosion layer and extending its service life. In addition, the large opening area provides convenience for the later maintenance of the anti-corrosion layer, greatly reducing maintenance costs.

[0032] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
