Description

Technical Field

[0001] This utility model relates to the field of dust collection and treatment technology, and more specifically, to a silicon dust collection and treatment device. Background Technology

[0002] Currently, silicon material processing is widely involved in modern industrial production, such as semiconductor manufacturing, photovoltaic industry, and glass production. These production processes generate large amounts of silicon-dust-containing gases. Currently, the common method for treating these silicon-dust-containing gases is to introduce them into collection boxes for treatment. However, existing collection boxes have revealed several problems in practical applications. Firstly, their internal structural design is relatively simple, lacking efficient dust collection and separation mechanisms. This results in uneven dust distribution within the collection box, with excessive dust accumulation in some areas and low collection efficiency in other areas, leading to poor overall collection performance.

[0003] On the other hand, when dust accumulates inside the collection box to a certain level and cleaning and maintenance are required, existing equipment often has to be shut down for cleaning. This not only interrupts the production process, reduces production efficiency, and increases production costs, but may also lead to the idleness of other equipment on the production line, further affecting the normal operation of the entire production system. Furthermore, frequent downtime for cleaning also impacts the equipment's lifespan, increasing maintenance costs and replacement frequency. Therefore, developing a device that overcomes these shortcomings, achieves efficient and continuous collection and processing of silicon dust, and is easy to clean and maintain is of significant practical importance. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a silicon dust collection and treatment device, which aims to improve the problem that existing equipment often has to be stopped before cleaning operations can be carried out when cleaning and maintenance are required.

[0006] In a preferred embodiment of this utility model, a rotating nozzle is installed at the top of the inner wall of the collection box, and a water inlet pipe is installed at the top of the rotating nozzle. The top of the water inlet pipe passes through the collection box and extends to the outside.

[0007] In a preferred embodiment of this utility model, an observation window is provided on one side of the collection box.

[0008] In a preferred embodiment of this utility model, the partition plate is provided with a plurality of circular holes, which are equidistantly arranged on the partition plate.

[0009] In a preferred embodiment of this utility model, the adjustment assembly includes a U-shaped frame, a first motor, and a second rotating shaft. One end of the first rotating shaft passes through one side of the collection box and is fixedly mounted with a first bevel gear. The U-shaped frame is fixedly mounted on the outside of the collection box. The second rotating shaft is rotatably mounted between the two sides of the inner wall of the U-shaped frame. Multiple second bevel gears are fixedly mounted on the second rotating shaft. The first bevel gear and the second bevel gear are meshed and connected. The first motor is fixedly mounted on one end of the second rotating shaft. The multiple first bevel gears and the multiple second bevel gears correspond one-to-one.

[0010] In a preferred embodiment of this utility model, a limiting plate is fixedly installed on the outer side of the first rotating shaft, and a horizontal plate that cooperates with the limiting plate is fixedly installed on the outer side of the collection box. The horizontal plate allows the limiting plate to rotate repeatedly within 180°.

[0011] In a preferred embodiment of this utility model, the driving assembly includes a threaded rod and a second motor. The threaded rod is rotatably mounted between the two sides of the inner wall of the collection box. The second motor is fixedly mounted at one end of the threaded rod. A vertical plate is fixedly mounted at the bottom end of the scraper. The vertical plate is threaded onto the threaded rod. T-shaped grooves matching the vertical plate and the scraper are provided on both sides of the inner wall of the collection box. When the multiple partitions rotate to form an isolation plate, the scraper slides in contact with the bottom end of the partition.

[0012] In a preferred embodiment of this utility model, a protective plate is fixedly installed between the two sides of the inner wall of the collection box. The protective plate is arc-shaped, and the vertical plate is slidably installed on the protective plate.

[0013] In a preferred embodiment of this utility model, the filter screen is slidably connected to the inner wall of the air outlet pipe, a pull rod is fixedly installed at the top of the filter screen, a horizontal plate is fixedly installed at the top of the pull rod, and a limiting groove matching the horizontal plate is provided at the top of the inner wall of the air outlet pipe.

[0014] The beneficial effects of this utility model are:

[0015] High-efficiency collection and separation: This invention utilizes a rotating nozzle within the collection box to spray the gas containing silica dust, causing the dust to quickly gather and adhere to the partition. Simultaneously, water droplets fall through the circular holes in the partition into the bottom of the collection box, achieving highly efficient separation of dust and gas. Furthermore, a filter screen installed inside the exhaust pipe further filters the discharged gas, ensuring it meets environmental standards and effectively reducing silica dust pollution.

[0016] Continuous operation and automatic cleaning: The equipment's adjustment and drive components work together. When there is a lot of dirt on the partition, the equipment can be started without stopping operation. Starting the first motor rotates the partition 180°, allowing the cleaned side to continue collecting dust, while the dirty side moves to a position for easier cleaning. Then, the second motor is started, moving the scraper to clean the partition. The cleaned dirt is discharged through the discharge pipe. This design enables continuous operation, greatly improving production efficiency and reducing production costs associated with downtime for cleaning.

[0017] Easy to observe and maintain: An observation window on one side of the collection box allows operators to easily monitor dust collection and equipment operation, enabling timely detection and appropriate action. Meanwhile, the filter screen slides along the inner wall of the exhaust pipe and is secured by a pull rod and crossbar, facilitating disassembly and cleaning, further enhancing the equipment's ease of maintenance.

[0018] Sturdy structure and long service life: The limiting plate installed on the outside of the first rotating shaft cooperates with the horizontal plate on the outside of the collection box to limit the rotation angle of the rotating shaft, ensuring the stability of the partition during rotation and avoiding damage to the equipment due to excessive rotation. The protective plate installed on the inner wall of the collection box has an arc-shaped design, on which the vertical plate slides. This not only protects the drive components but also reduces wear on the scraper during movement, extending the service life of the equipment. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Please see Figures 1-4 The present invention provides a technical solution: a silicon dust collection and treatment device, including a collection box 110, an air inlet pipe 111 and an air outlet pipe 112 respectively installed on both sides of the collection box 110, a filter screen plate 1121 installed inside the air outlet pipe 112, a plurality of first rotating shafts 113 rotatably installed between the two sides of the inner wall of the collection box 110, a partition plate 120 fixedly installed on the first rotating shaft 113, the plurality of partition plates 120 being parallel to each other and forming an isolation plate by rotation, an adjustment component installed at one end of the first rotating shaft 113, a scraper 130 cooperating with the partition plate 120 slidably installed on the inner wall of the collection box 110, a drive component installed on the scraper 130, and a discharge pipe 114 with a valve installed at the bottom of one side of the collection box 110.

[0029] In some specific implementations, a rotating nozzle 115 is installed at the top of the inner wall of the collection box 110. A water inlet pipe 116 is installed at the top of the rotating nozzle 115, extending through the collection box 110 and outwards. Water is introduced through the water inlet pipe 116, allowing the rotating nozzle 115 to spray water evenly inside the collection box 110. This ensures that after the silica dust-containing gas enters the collection box 110, the dust and water droplets come into full contact, accelerating dust settling and improving collection efficiency. Simultaneously, the moistened dust is less likely to become airborne, further preventing secondary pollution and enhancing the treatment effect on silica dust. Furthermore, the rotating nozzle 115 and water inlet pipe 116 also provide a certain degree of cleaning inside the collection box 110, reducing dust adhesion to the box walls and other locations, and maintaining the cleanliness of the inside of the collection box 110.

[0030] In some specific implementation schemes, an observation window 117 is provided on one side of the collection box 110. Operators can visually observe the collection status of silicon dust inside the collection box 110 at any time through the observation window 117, such as the degree of dust accumulation on the partition 120 and whether there are any abnormal accumulation phenomena. They can also observe the equipment's operating status, such as whether the rotation of the partition 120 and the movement of the scraper 130 are normal. This facilitates timely detection of problems and the implementation of corresponding measures, such as arranging cleaning in advance before excessive dust accumulation, ensuring stable equipment operation, and improving the timeliness and convenience of equipment maintenance. Through the observation window 117, the water spraying effect of the rotating nozzle 115 can also be observed during equipment operation, allowing for timely adjustment of parameters such as the water inlet volume.

[0031] In some specific implementations, the partition 120 is provided with multiple circular holes, which are equidistantly arranged on the partition 120. Water droplets can fall through the circular holes into the bottom of the collection box 110, forming a certain water layer at the bottom of the collection box 110. This helps to further adsorb and settle the dust falling from above, enhancing the collection effect of silicon dust. At the same time, the presence of the circular holes can also balance the air pressure on both sides of the partition 120, making the partition 120 rotate more smoothly and ensuring the stability of equipment operation. The circular holes can also make the airflow distribution within the collection box 110 more uniform, improving the uniformity of dust collection.

[0032] Please see Figure 3 The adjustment assembly includes a U-shaped frame 140, a first motor 141, and a second rotating shaft 142. One end of the first rotating shaft 113 passes through one side of the collection box 110 and is fixedly mounted with a first bevel gear. The U-shaped frame 140 is fixedly mounted on the outside of the collection box 110. The second rotating shaft 142 is rotatably mounted between the two sides of the inner wall of the U-shaped frame 140. Multiple second bevel gears are fixedly mounted on the second rotating shaft 142. The first bevel gear and the second bevel gear are meshed and connected. The first motor 141 is fixedly mounted on one end of the second rotating shaft 142. The multiple first bevel gears and the multiple second bevel gears correspond one-to-one.

[0033] In some specific implementations, a limiting plate 143 is fixedly installed on the outer side of the first rotating shaft 113, and a horizontal plate 144 that cooperates with the limiting plate 143 is fixedly installed on the outer side of the collection box 110. The horizontal plate 144 allows the limiting plate 143 to rotate repeatedly within 180°, thereby limiting the rotation angle of the first rotating shaft 113 and the partition 120. This prevents the partition 120 from rotating excessively, ensuring the safety and stability of the equipment operation and extending the service life of the equipment. Simultaneously, it provides precise control of the rotation angle.

[0034] Please see Figure 4 and Figure 5 The drive assembly includes a threaded rod 131 and a second motor 132. The threaded rod 131 is rotatably mounted between the two sides of the inner wall of the collection box 110. The second motor 132 is fixedly mounted at one end of the threaded rod 131. A vertical plate 134 is fixedly mounted at the bottom of the scraper 130. The vertical plate 134 is threaded onto the threaded rod 131. T-shaped grooves matching the vertical plate 134 and the scraper 130 are provided on both sides of the inner wall of the collection box 110. When multiple partitions 120 rotate to form a partition plate, the scraper 130 slides in contact with the bottom of the partition 120.

[0035] In some specific implementations, a protective plate 133 is fixedly installed between the two sides of the inner wall of the collection box 110. The protective plate 133 is arc-shaped, and the vertical plate 134 is slidably installed on the protective plate 133. The protective plate 133 provides a stable sliding track for the vertical plate 134, preventing the vertical plate 134 from shifting during movement and ensuring that the scraper 130 always maintains good contact with the partition 120, thereby improving the cleaning effect. The protective plate 133 also protects components such as the threaded rod 131, preventing impurities such as silica dust from entering, reducing component wear, and extending the service life of the equipment. The arc-shaped design of the protective plate 133 conforms to the movement trajectory of the scraper 130, which can better guide the movement of the vertical plate 134 and improve the smoothness of equipment operation.

[0036] Please see Figure 6 The filter screen 1121 is slidably connected to the inner wall of the exhaust pipe 112. A pull rod 1122 is fixedly installed at the top of the filter screen 1121, and a horizontal plate 1123 is fixedly installed at the top of the pull rod 1122. A limiting groove matching the horizontal plate 1123 is provided at the top of the inner wall of the exhaust pipe 112, facilitating the removal of the filter screen 1121 from the exhaust pipe 112. After the equipment has been running for a period of time, the filter screen 1121 can be removed for cleaning or replacement to ensure its filtration effect, prevent the gas discharge efficiency from being affected by filter clogging, and ensure the normal operation of the equipment and compliance of exhaust gas emissions. This design facilitates quick maintenance by operators, eliminating the need for complicated disassembly steps and saving maintenance time and costs.

[0037] Working principle: Gas containing silica dust enters the collection box 110 through the inlet pipe 111. At this time, the dust in the gas is collected on the partition plate 120 by the rotating nozzle 115. At the same time, water droplets enter the bottom of the collection box 110 through the round hole. The gas is then filtered by the filter screen plate 1121 and discharged from the outlet pipe 112. When there is a lot of dirt on the partition plate 120, the first motor 141 is started to drive the second rotating shaft 142 to rotate. The rotation of the second rotating shaft 142 drives the first rotating shaft 113 to rotate through the cooperation of the first bevel gear and the second bevel gear. The rotation of the first rotating shaft 113 drives the partition plate 120 to rotate 180°. Finally, the second motor 132 is started to drive the threaded rod 131 to rotate. The rotation of the threaded rod 131 drives the scraper 130 to move through the vertical plate 134 to clean the partition plate 120. Finally, the valve is opened to discharge the dirt from the discharge pipe 114.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
