Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a low-damage drum screening device for ceramic filter sheets and sponges. Background Technology

[0002] Ceramic filter sheets are a type of filter medium made from ceramic materials. They are widely used in the purification of liquids and gases. Due to their unique physicochemical properties, such as high heat resistance, excellent chemical stability, good mechanical strength, and adjustable pore structure, ceramic filter sheets have been widely used in many industries.

[0003] The "sponge replication method" is a common process for manufacturing porous ceramic filter sheets. The principle is to use a sponge as a template structure, coat its three-dimensional skeleton with ceramic slurry, and after drying and high-temperature sintering, remove the sponge skeleton to finally form a lightweight, high-strength porous ceramic material with interconnected pores. The slag shedding rate in the finished ceramic filter sheet is a direct parameter that affects the value of the ceramic filter sheet and the customer experience. In the current ceramic filter sheet production process, after the sponge is cut, it needs to be screened to remove the slag from the sponge block before it is put into production.

[0004] Utility model patent CN216800518U discloses a drum screener, including a support frame and a drum frame. A motor is mounted on the support frame. The drum frame includes a first circular plate and a second circular plate arranged coaxially. The first circular plate is drivenly connected to the output shaft of the motor. The first circular plate and the second circular plate are connected by multiple connecting plates. The multiple connecting plates are evenly distributed along the circumference of the first circular plate and perpendicular to the first circular plate. A screen plate is detachably connected between two adjacent connecting plates. The screen plate has multiple screen holes. When it is necessary to clean the screen holes, only the screen plate needs to be removed for cleaning, without disassembling the entire drum frame, making operation convenient.

[0005] In the above technical solution, the screen plate is set to be detachable in order to facilitate cleaning of the screen holes. However, when the screen plate and the connecting plate overlap, there is a certain gap at the connection. During screening, the ceramic filter sponge is easily caught on the edge of the screen plate. Furthermore, the machine needs to be stopped when disassembling and assembling the screen plate, which affects the processing efficiency. Utility Model Content

[0033] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.

[0034] like Figure 1-7 As shown, the present invention provides a low-damage drum screening device for ceramic filter sponges, comprising a frame 1, a roller support 2, a drum screen 3, a protective mechanism 4, a drive motor 5, and a purging mechanism 6.

[0035] Among them, frame 1 is a frame structure used for overall support.

[0036] The roller support 2 is fixedly mounted on the frame 1 and consists of rollers and a support. The rollers are rotatably mounted on the support and are used to support the drum screen 3. In order to ensure the stability of the drum screen 3 when rotating, the roller support 2 is provided at two points at each end of the frame 1 to support the two ends of the drum screen 3. In order to reduce the transmission of vibration to the drum screen 3, the rollers on the roller support 2 are rubber-coated rollers, which have a strong buffering and vibration reduction effect.

[0037] The drum screen 3 is used to screen the slag on the ceramic filter sponge after production, reducing the slag loss rate and improving the yield rate. The drum screen 3 includes a drum frame 31 and a screen 32. The drum frame 31 is used to support and fix the screen 32, improving the overall structural strength of the screen 32. The drum frame 31 includes support rods 311, end plates 312 and support rings 313. The support rods 311 are set inside the screen 32 and are spaced apart from the screen 32. The gap between the support rods 311 and the screen 32 is used to accommodate the ceramic filter sponge. The end plates 312 are fixedly set at both ends of the support rods 311, and the edges of both ends of the screen 32 are fixedly connected to the end plates 312. The end plates 312 seal both ends of the screen 32 to prevent material leakage and ensure overall sealing.

[0038] To improve overall durability and prevent the screen mesh 32 from being squeezed during the rotation of the drum screen 3, a support ring 313 is fixedly installed on the end plate 312, and the support ring 313 abuts against the roller support 2. In order to prevent the drum screen 3 from shifting laterally, the diameter of the support ring 313 is smaller than the diameter of the end plate 312. When the drum screen 3 shifts laterally, the end plate 312 will be blocked by the rollers on the roller support 2, thereby limiting the drum screen 3, reducing friction and improving the stability of the drum screen 3 during rotation.

[0039] The protective mechanism 4 is used to block the material inlet 301 on the screen 32. The protective mechanism 4 includes a limiting frame 41 and a cover 42. The limiting frame 41 is a rectangular frame and is fixedly installed inside the screen 32. The screen 32 has a material inlet 301, and the limiting frame 41 is located at the edge of the material inlet 301. The limiting frame 41 covers the edge of the material inlet 301 to prevent the edge of the material inlet 301 from catching the ceramic filter sponge. One end of the cover 42 is rotatably installed on the limiting frame 41, and after the cover 42 is closed, its edge abuts against the limiting frame 41. The limiting frame 41 limits the cover 42 to prevent it from being inserted into the screen 32 and to prevent the edge of the cover 42 from catching the ceramic filter sponge. It also covers the gap between the cover 42 and the material inlet 301.

[0040] To secure the cover screen 42, the protective mechanism 4 also includes a stop plate 43, a screw 44, and a fixing nut 45. The stop plate 43 is fixedly installed at the other end of the cover screen 42, and after the cover screen 42 is closed, the stop plate 43 abuts against the screen 32, which limits the position of the cover screen 42 and improves the structural strength at the edge of the cover screen 42 at this end, preventing deformation at the edge of the cover screen 42 during repeated use and affecting the normal fixation of the cover screen 42. The screw 44 is fixedly installed on the limiting frame 41, and the screw 44 passes through and extends out of the cover screen 42. The stop plate 43 has an insertion hole, and after the cover screen 42 is closed, the screw 44 passes through the stop plate 43 through the insertion hole. The fixing nut 45 is installed on the screw 44 through a threaded engagement, and the fixing nut 45 clamps the stop plate 43, which limits and fixes the cover screen 42, preventing the cover screen 42 from opening during the operation of the drum screen 3.

[0041] The drive motor 5 is used to drive the drum screen 3 to rotate, thereby screening the ceramic filter sponge. The drive motor 5 is fixedly mounted on the frame 1, and the output end of the drive motor 5 is connected to a roller on one of the roller supports 2 on the frame 1. The drive motor 5 drives the drum screen 3 to rotate through the roller, avoiding a direct hard connection between the drive motor 5 and the drum screen 3, and reducing the transmission of vibration to the drum screen 3.

[0042] The purging mechanism 6 is used to purge the screen 32 in reverse to prevent the slag falling from the ceramic filter sponge from clogging the screen 32. The purging mechanism 6 includes a bracket 61, a support arm 62, and an air knife 63. The two ends of the bracket 61 are fixedly mounted on the frame 1 to provide support. One end of the support arm 62 is rotatably mounted on the bracket 61, and the air knife 63 is fixedly mounted on the other end of the support arm 62. The rotation of the support arm 62 can adjust the orientation of the air outlet of the air knife 63, so that it can be aimed at the bottom of the screen 32 for purging. The screen 32 is cleaned by the reverse purging of the air knife 63 to prevent the slag from clogging the screen holes on the screen 32. The cleaning process does not require stopping the machine and does not affect the overall processing efficiency.

[0043] To fix the orientation of the air outlet of the air knife 63 and align it with the screen 32, the blowing mechanism 6 also includes a retaining ring 64, which is rotatably mounted on the bracket 61. A slot 601 is provided on the support arm 62, and the slot 601 is inclined, with the retaining ring 64 engaging with the slot 601. Figure 6 As shown, after the buckle 64 engages with the slot 601, it limits the support arm 62, tightens the support arm 62 to prevent it from rotating upward, thereby preventing the air knife 63 from falling during the purging process.

[0044] To prevent debris from falling into the air outlet of the air knife 63, the end of the support arm 62 furthest from the bracket 61 is inclined, reducing the distance between the air knife 63 and the screen 32, improving the purging effect, and simultaneously shifting the center of gravity towards the end closer to the air knife 63. Figure 7As shown, when the support arm 62 loses the restraint of the buckle 64, the air knife 63 falls under the action of gravity, causing the support arm 62 to rotate upward. After rotation, the air outlet of the air knife 63 faces the downward angle of the screen 32, preventing the slag that falls during non-blowing time from entering the air outlet of the air knife 63.

[0045] To ensure the stability of the air knife 63 when it is fixed, two support arms 62 are provided on the bracket 61, and the two support arms 62 are symmetrically arranged in the vertical section about the width direction of the bracket 61. The purging mechanism 6 also includes a crossbeam 65, the two ends of which are fixedly connected to the two support arms 62 on the same bracket 61. The two support arms 62 at both ends of the air knife 63 are connected into one unit by the crossbeam 65, which improves the overall firmness and stability, and is also easy to hold and convenient for manual operation.

[0046] To further improve purging efficiency, such as Figure 1 and Figure 2 As shown, there are two blowing mechanisms 6 on the frame 1, and the two blowing mechanisms 6 are symmetrically arranged in the vertical section about the length of the drum screen 3. The air knife 63 is arranged parallel to the axis of the drum screen 3, which can blow the bottom of both ends of the drum screen 3 at the same time, thus improving the cleaning efficiency.

[0047] The method of using the low-damage drum screening device for ceramic filter sponges according to this utility model is as follows:

[0048] During loading, first remove the fixing nut 45, then open the cover 42, and put the ceramic filter sponge into the drum screen 3 through the feed port 301. After loading, cover the cover 42 and fix it with the fixing nut 45. Start the device, and the drive motor 5 drives the drum screen 3 to rotate through the rollers on the roller support 2 to screen the slag on the ceramic filter sponge, achieving high-precision slag separation while ensuring the integrity of the sponge structure. When the screen 32 is blocked and needs to be cleaned, press down the crossbeam 65 to make the support arm 62 rotate downward, and then rotate the buckle 64 to make the buckle 64 engage with the slot 601, which limits the support arm 62. At this time, the air outlet of the air knife 63 on the support arm 62 is aligned with the screen 32. Use the air knife 63 to blow the screen 32 in reverse to clean the slag blocking the screen 32. After cleaning, reset the air knife 63.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
