Description

Technical Field

[0001] This utility model relates to the field of filter material regeneration technology, specifically to a filter element cleaning device. Background Technology

[0002] In the post-processing stages of polysilicon production, dust removal equipment is an essential and crucial device. Its internal dust filter is specifically designed to intercept the fine silicon powder generated during production. On the one hand, it prevents silicon powder from drifting and contaminating the finished product, reducing product purity; on the other hand, it prevents operators from inhaling dust and harming their health, while also eliminating the safety hazards of silicon powder accumulation such as spontaneous combustion and explosion.

[0003] The silicon powder produced during polycrystalline silicon production has special characteristics: the particle size is only 0.1~10 micrometers, and the powder is extremely sticky. Once it adheres to the filter element, it is easy to clump together and completely block the filter pores inside the filter element.

[0004] Currently, there is no integrated cleaning equipment on the market specifically adapted to polycrystalline silicon viscous silicon powder. Filter element cleaning and drying are separate independent equipment, which can only be operated manually. The process is scattered, with high labor costs and low efficiency. Blowing, washing and drying are divided into three independent equipment. Filter elements have to be manually moved and disassembled. The whole cleaning process takes a long time. When cleaning large batches of filter elements, the production capacity cannot keep up with the production needs of the workshop.

[0005] There are blind spots in the cleaning process, the filter element is not cleaned evenly, the existing blow nozzle can only be fixed in direction and can only rinse one side of the filter element. The inner side of the filter element cylinder and the upper and lower end faces cannot be cleaned completely. The cleaning degree of the same filter element is inconsistent. To ensure the cleaning effect, the filter element must be adjusted repeatedly, which further leads to the time-consuming and labor-intensive cleaning operation. Utility Model Content

[0006] The purpose of this invention is to develop a filter element cleaning device that eliminates the need for manual handling between the cleaning and drying processes, and uses drive wheels to rotate the filter element during the cleaning and drying process to avoid dead corners in the cleaning and drying process.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-4 As shown, this utility model discloses a filter element cleaning device, including a body 1. The body 1 has a rectangular parallelepiped shape, and from one end to the other along its length, it is provided with a material platform 101, a first cleaning chamber 102, a second cleaning chamber 103, and a drying chamber 104. The body 1 is also provided with a clamping assembly 2 for clamping and moving the filter element. The clamping assembly 2 drives the filter element to move, realizing the loading and unloading of the filter element on the material platform 101, the cleaning in the first cleaning chamber 102 and the second cleaning chamber 103, and the drying in the drying chamber 104.

[0028] The material platform 101 is provided with an arc-shaped groove 105. The central angle corresponding to the cross-sectional shape of the groove 105 does not exceed 180 degrees. That is, the cross-sectional shape of the groove 105 is a minor arc or a semicircle, so that the filter element can be smoothly placed into the groove 105.

[0029] The filter element includes a body and end caps at both ends. The outer wall of the body is wavy, and the outer diameter of the end caps is larger than that of the body. The clamping assembly 2 clamps the body portion of the filter element. The groove 105 extends laterally through the material table 101. The length of the groove 105 is less than the length of the filter element body, so that after the filter element is placed in the groove 105, part of the filter element body is placed inside the groove 105, while the end caps at both ends and the other part of the filter element body are outside the groove 105, so that the clamping assembly 2 can clamp the body portion of the filter element from both sides of the groove 105.

[0030] The first cleaning chamber 102 performs ultrasonic cleaning on the filter element. The first cleaning chamber 102 is rectangular in shape. Multiple ultrasonic transducers 106 arranged in a uniform matrix are located at the bottom of the first cleaning chamber 102. An ultrasonic generator, electrically connected to the ultrasonic transducers 106, is located outside the first cleaning chamber 102. A first drain pipe is located at the bottom of the first cleaning chamber 102, discharging wastewater into a wastewater tank. An inlet pipe and an overflow pipe are located at the top of the first cleaning chamber 102.

[0031] Currently, the cleaning of silicon powder filter elements generally adopts a single high-pressure air purging method. Relying solely on the high-pressure airflow to impact the surface dust of the filter element, high-pressure purging can only blow away loose dust on the surface of the filter element. Silicon powder stuck deep in the filter pores cannot be completely cleaned. After repeated use, the filter element becomes increasingly clogged, the ventilation and filtration efficiency drops significantly, and the filter element can only be replaced frequently, resulting in high consumable procurement costs.

[0032] This application replaces high-pressure air purging with ultrasonic cleaning in the first cleaning chamber 102. The ultrasonic frequency is controlled at 33-40kHz. By utilizing the vibration of ultrasonic waves, stubborn dust and impurities inside the filter element are loosened, and silica powder and impurities inside the filter element are removed. Compared with the high-pressure air purging cleaning method, the cleaning effect and filter element descaling rate can be improved.

[0033] The second cleaning chamber 103 sprays water to rinse the filter element. The second cleaning chamber 103 is rectangular in shape, and its inner wall, that is, its bottom and four side walls, are covered with multiple nozzles 107 arranged in a matrix. The water spray pressure of the nozzles 107 is controlled at 0.3-0.6 MPa. A second drain pipe is provided at the bottom of the second cleaning chamber 103, which discharges the wastewater to a wastewater tank.

[0034] Currently, ordinary water cannot dissolve stubborn silica powder, especially sticky silica powder and silica powder mixed with metal chloride impurities. Even with water rinsing, only a small amount of surface dust can be washed away, and the internal clumps of dust inside the filter pores remain uncleaned. Ordinary water can also easily corrode the two mainstream filter materials: sintered metal and PTFE membrane filters. In this application, the liquid used for spray rinsing is a mixture of deionized water and a cleaning agent. The cleaning agent uses a neutral composite formula adapted to polycrystalline silicon dust, and its components include an oxidant, an additive, and deionized water. The oxidant has a mass fraction of 3%-5%, the additive (neutral chelating agents such as sodium citrate, sodium gluconate, and EDTA-disodium) has a mass fraction of 8%-10%, and the remainder is deionized water. Through spray cleaning, the scale transformation and descaling are carried out simultaneously, effectively dissolving stubborn impurities such as silica powder and metal chlorides, and avoiding corrosion of the filter material (sintered metal filter or PTFE membrane filter).

[0035] The drying chamber 104 dries the filter element after two cleanings. The drying chamber 104 is rectangular in shape, and its two opposite side walls are respectively equipped with an air inlet structure and an air outlet structure. The air inlet structure blows hot drying air into the filter element inside the drying chamber 104, and the air outlet structure exhausts and removes moisture.

[0036] The air inlet structure includes an air guide box 108 located on the side wall of the drying chamber 104. The air guide box 108 is connected to the drying chamber 104. Multiple electric heating tubes 109 are installed inside the air guide box 108. Multiple air inlet pipes 110 are connected to the top of the air guide box 108. The airflow delivered by the external fan enters the air guide box 108 through the air inlet pipes 110. The electric heating tubes 109 heat the airflow, causing the hot air to be blown into the drying chamber 104. The air outlet structure includes multiple slots 111 located on the side wall of the drying chamber 104 opposite the air guide box 108. The multiple slots 111 are elongated and horizontally opened, and the multiple slots 111 are arranged vertically and at equal intervals.

[0037] The clamping assembly 2 includes a guide rail 201 located above the machine body 1. The guide rail 201 is arranged along the length of the machine body 1. A support structure is provided on the machine body 1 or on its side, and the guide rail 201 is mounted on the support structure. Specifically, the support structure includes four columns, and a rectangular frame is provided on each of the four columns. The guide rail 201 is mounted on the frame.

[0038] A slide block 202 is slidably mounted on the guide rail 201. A traveling wheel that cooperates with the guide rail 201 is rotatably mounted on the slide block 202. The traveling wheel rotates and rolls on the guide rail 201, causing the slide block 202 to slide along the guide rail 201. A first motor (not shown in the figure) is correspondingly mounted on the slide block 202 and is connected to the traveling wheel via a transmission.

[0039] The slide 202 has a vertically arranged lifting drive 203 at its bottom, and a horizontally arranged support 204 at its bottom. The slide 202 moves on the guide rail 201, causing the support 204 to move laterally, and the lifting drive 203 drives the support 204 to move longitudinally.

[0040] The support 204 has a vertically arranged support arm 205 at each end, and a hanging member 206 for supporting the filter element is provided at the bottom end of the support arm 205. The hanging members 206 at the bottom end of the two support arms 205 are respectively hung on the filter element body inside the end caps of the filter element. The support 204 is provided with a horizontally arranged bidirectional drive member 207. The bidirectional drive member 207 has two retractable and coaxially sliding ends, and the two support arms 205 are respectively connected to the two ends of the bidirectional drive member 207.

[0041] The lifting drive component 203 can be a cylinder or an electric push rod, which drives the support 204 to rise and fall vertically. The bidirectional drive component 207 can be a double-rod cylinder, whose two piston rods can extend and retract synchronously in opposite directions to adjust the distance between the two arms 205 so that the distance between the two hooks 206 matches the length of the filter element. The bidirectional drive component 207 can also be an electric push rod respectively set at both ends of the support 204, with the two electric push rods controlling the position of the two arms 205 respectively. Since the slide 202 needs to slide along the guide rail 201, in order to make the clamping assembly 2 structure compact, the lifting drive component 203 and the bidirectional drive component 207 are preferably electric push rods.

[0042] The hook-shaped connector 206 has a flared top opening that gradually tapers downwards, allowing it to hold filter cartridges of different outer diameters. The inner wall of the connector 206 in contact with the filter cartridge is lined with a layer of polytetrafluoroethylene (PTFE). One arm 205 also features a drive mechanism that rotates the filter cartridge. When the clamping assembly 2 moves the filter cartridge for cleaning and drying, the drive mechanism causes the filter cartridge to rotate on the two connectors 206, improving the cleaning and drying effect.

[0043] The drive mechanism includes a drive groove 210 on the upper support arm 205 of the hanger 206. A crank 209 is hinged near the bottom of the drive groove 210. The crank 209 is a bent rod. A drive wheel 208 is rotatably connected to the free end of the crank 209, i.e., the end of the crank 209 away from the drive groove 210. A second motor 211, which is drively connected to the drive wheel 208, is located at the free end of the crank 209. The outer circumferential wall of the drive wheel 208 is wavy and has multiple protrusions evenly arranged in the circumferential direction. The wavy outer wall of the drive wheel 208 cooperates with the outer wall of the filter element body. When the drive wheel 208 rotates, the protrusions on its outer wall push the wavy outer wall of the filter element body, thereby driving the filter element to rotate. The outer wall of the drive wheel 208 is provided with a protective layer, which is made of plastic or rubber, such as nylon, rubber, or polyurethane.

[0044] A third motor 213 is mounted on the support arm 205 outside the drive slot 210. The third motor 213 is fixed to the support arm 205 by a support rod or other structure. A drive rod 212 is connected to the output shaft of the third motor 213. The drive rod 212 is L-shaped and includes a first rod part and a second rod part that are perpendicularly connected to each other. One end of the first rod part is connected to the output shaft of the third motor 213, and the other end of the first rod part is connected to the second rod part. The first rod part is perpendicular to the rotation axis of the crank 209, and the second rod part is parallel to the rotation axis of the crank 209. The drive groove 210 has a sliding groove 214 on its side wall to accommodate the passage and sliding of the second rod. The sliding groove 214 is an arc with the connection between the first rod and the output shaft of the third motor 213 as the center. The third motor 213 drives the drive rod 212 to swing. The first rod of the drive rod 212 swings, and the second rod slides in the sliding groove 214. The second rod slides below the curved rod 209 in the drive groove 210. The third motor 213 drives the drive rod 212 to swing, thereby realizing the reset and release of the curved rod 209.

[0045] When the clamping assembly 2 clamps the filter element, the third motor 213 operates, driving the drive rod 212 to swing, causing the second part of the drive rod 212 to slide upward along the slide groove 214. The second part pushes the crank rod 209 upward until the crank rod 209 and the drive wheel 208 at its end disengage from the hanger 206. When the clamping assembly 2 drives the filter element to rotate, the third motor 213 operates, driving the drive rod 212 to swing, causing the second part of the drive rod 212 to slide downward along the slide groove 214. During the downward movement of the second part, the crank rod 209 and the drive wheel 208 at its end, as well as the second motor 211, swing downward under their own weight. The second part slides down to the bottom of the slide groove 214. During this process, the drive wheel 208 contacts the outer wall of the filter element body, and the crank rod 209 stops sliding down. At this time, the drive wheel 208 contacts the outer wall of the filter element body under its own weight, and the second motor 211 drives the drive wheel 208 to rotate. The drive wheel 208 drives the filter element to rotate on the hanger 206. When the filter element is stopped, the third motor 213 drives the second rod of the drive rod 212 to slide upward, pushing the crank rod 209 upward to disengage it.

[0046] The third motor 213 and its corresponding wiring are waterproofed. Furthermore, the drive wheel 208 can also be a round rubber roller, suitable for smaller filter elements. For larger filter elements with a certain weight, the drive wheel 208 has a wavy outer wall, which facilitates rotation. In this embodiment, only one support arm 205 has a drive wheel 208, sufficient for driving filter elements of standard size. If the filter element is larger, both support arms 205 can be equipped with cranks 209 and drive wheels 208, and the two drive wheels 208 must rotate synchronously.

[0047] The filter element to be cleaned is placed in the groove 105 of the material platform 101. The clamping assembly 2, through a series of movements, positions the two hooks 206 at the lower sides of the filter element. Then, the hooks 206 rise, allowing the sides of the filter element to enter the hooks 206. The clamping assembly 2 drives the supported filter element sequentially into the first cleaning chamber 102 and the second cleaning chamber 103 for cleaning. Within the first and second cleaning chambers 102 and 103, the third motor 213 releases the crank 209, causing the drive wheel 208 to adhere to the filter element. The drive wheel 208 then rotates, driving the filter element to rotate, improving the cleaning effect. Especially in the second cleaning chamber 103, the filter element's rotation provides a wider cleaning angle to the nozzles 107, eliminating cleaning dead zones. Cleaning dead zones refer to areas where, for example, the top of the filter element is difficult to spray, or unavoidable blank spray areas exist due to the spacing of the nozzles 107. During the cleaning and rinsing of the filter element in the first cleaning chamber 102 and the second cleaning chamber 103, the clamping assembly 2 also slowly moves the filter element from one end to the other, which improves the cleaning effect. Especially in the first cleaning chamber 102, the filter element moves slowly from one end to the other, and the impurities removed by ultrasonic cleaning have virtually no chance of re-adhering to the filter element. After cleaning, the clamping assembly 2 carries the filter element into the drying chamber 104. In the drying chamber 104, the hot air output from the air guide box 108 dries the filter element. During this process, the filter element is driven to rotate, so that air can be impacted at all parts of its circumference, improving the drying effect. After cleaning and drying, the clamping assembly 2 puts the filter element back into the groove 105 of the material table 101.

[0048] This invention integrates ultrasonic cleaning, spray cleaning, and drying operations. The clamping assembly 2 automatically transports the filter element between three working areas for cleaning and drying, eliminating manual handling and significantly improving efficiency. Ultrasonic cleaning replaces high-pressure blowing, utilizing ultrasonic vibrations to loosen stubborn dust and impurities inside the filter element, enhancing cleaning effectiveness. Spray cleaning uses a cleaning agent to simultaneously transform and remove scale, effectively dissolving stubborn impurities such as silica powder and metal chlorides, further improving cleaning efficiency and effectiveness. Efficiency is improved by using hot air to quickly dry the filter element after cleaning. At the same time, during the cleaning and drying process, the drive wheel 208 on the clamping assembly 2 can drive the filter element to rotate, eliminating dead corners in the cleaning and drying process and further improving the cleaning and drying effect and efficiency. The hook-shaped bracket 206 and the adjustable spacing of the support arm 205, along with the swing trajectory of the drive wheel 208 passing through the inner area of ​​the bracket 206, can accommodate filter elements of different lengths and outer diameters, improving the versatility of the equipment.

[0049] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
