A rotary iron removal device for silica production

Abstract

This utility model relates to the field of silica production technology and discloses a rotary iron removal device for silica production, including a base plate, a support platform fixedly installed on the top of the base plate, a groove in the support platform, and a placement frame fixedly installed on the top of the support platform. This rotary iron removal device for silica production, through the inclusion of a control component, allows the output shaft of a motor to drive a rotating rod and a cylinder to rotate. Simultaneously, a connecting plate fixed to the surface of the cylinder rotates synchronously. When a fixed rod fixed to the surface of the support platform abuts against the tangent of a sliding rod, the sliding rod is forced to move a support block laterally along the surface of a horizontal rod. As the support block moves, a horizontal bar fixed to the bottom of the support block drives a scraper ring to slide along the surface of a strong magnetic rod, scraping away iron impurities remaining on the surface of the strong magnetic rod. This achieves rapid removal of iron impurities without stopping the machine, avoiding adhesion that could affect subsequent iron removal efficiency.

Description

Technical Field

[0001] This utility model relates to the field of silica production technology, specifically a rotary iron removal device for silica production. Background Technology

[0002] Silica, named for its similar uses to carbon black and its white color, can be categorized into precipitated silica and fumed silica based on its production method. These two types differ significantly in their production methods, properties, and applications. Fumed silica primarily uses silicon tetrachloride and air to produce silica, resulting in fine particles with a median particle size below 5 micrometers. Precipitated silica, on the other hand, is produced by adding sulfuric acid to sodium silicate, causing silica to precipitate. The median particle size is approximately 7-12 micrometers. In the precipitated silica production process, an acid-base reaction generates a silica slurry. This slurry is then filtered, washed to obtain a filter cake, and further processed by a pulper to produce a fine slurry. The typical process yields a fine slurry with a concentration of 20%, which is then spray-dried to obtain the final silica product. This series of processes introduces rust, particularly in the final spray-drying system, which can negatively impact downstream products.

[0003] Existing precipitated silica iron removal devices typically use strong magnetic rods to remove iron from the precipitated silica material. However, when a large amount of iron impurities remain on the strong magnetic rods, the operator needs to stop the equipment and manually remove the iron impurities from the strong magnetic rods, which is a complicated process. To address this issue, we propose a rotary iron removal device for precipitated silica production. Utility Model Content

[0004] The purpose of this invention is to provide a rotary iron removal device for the production of silica, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary iron removal device for silica production, comprising a base plate, a support platform fixedly installed on the top of the base plate, a groove formed in the support platform, a placement frame fixedly installed on the top of the support platform, and a fixing frame fixedly installed on the top of the base plate. A control component is provided within the support platform and the fixing frame, the control component comprising:

[0006] A scraper ring, wherein a crossbar is fixedly installed on the side of the scraper ring, and a support block is fixedly installed on the top of the crossbar;

[0007] The rotating component is used to remove iron from the silica material in the placement frame, thereby achieving rapid removal of iron impurities without stopping the machine and avoiding adhesion that affects the subsequent iron removal effect.

[0008] Preferably, the rotating component includes a flat rod that passes through the support block and is slidably connected to the support block. The flat rod is fixedly installed on the inner wall of the connecting plate, and the flat rod ensures the stability of the support block during movement.

[0009] Preferably, the inner wall of the connecting plate is fixedly connected to one end of the spring, and the other end of the spring is fixedly installed on the side of the support block. When the support block is no longer under force, it will spring up under the action of the spring.

[0010] Preferably, a sliding rod is fixedly installed on the top of the support block. The front end of the sliding rod has a triangular cross-section. When the cross-section of the sliding rod is pressed against something, it can drive the support block to slide.

[0011] Preferably, the connecting plate is fixedly installed on the arc surface of the cylinder, and a strong magnetic rod is fixedly installed on the arc surface of the cylinder. The arc surface of the strong magnetic rod is in contact with the inner wall of the scraper ring. When the cylinder rotates, the strong magnetic rod fixed on the cylinder surface and the connecting plate can rotate synchronously.

[0012] Preferably, a rotating rod is fixedly installed on the top of the cylinder, the rotating rod passes through the fixing frame and is rotatably connected to the fixing frame, a motor is fixedly installed on the top of the fixing frame, and the output shaft of the motor is fixedly connected to the rotating rod. When the output shaft of the motor is subjected to force, it can drive the rotating rod and the cylinder to perform circular motion.

[0013] Preferably, a fixing rod is fixedly installed on the side of the support platform. The fixing rod on the side of the support platform can cause the slide rod to move when it comes into contact with the tangential surface of the slide rod.

[0014] Compared with the prior art, this utility model provides a rotary iron removal device for the production of silica, which has the following advantages:

[0015] 1. This rotary iron removal device for silica production, equipped with a control component, allows the motor output shaft to drive the rotating rod and cylinder to rotate. Simultaneously, the connecting plate fixed to the cylinder surface rotates. When the fixed rod on the support platform surface abuts against the tangent of the sliding rod, the sliding rod is forced to move the support block laterally along the surface of the horizontal rod. As the support block moves, the horizontal bar fixed at the bottom of the support block drives the scraper ring to slide along the surface of the strong magnetic rod, scraping away iron impurities remaining on the surface of the strong magnetic rod. This achieves rapid removal of iron impurities without stopping the machine, preventing adhesion and ensuring effective iron removal.

[0016] 2. This rotary iron removal device for silica production has a rotating component. When the output shaft of the motor drives the rotating rod to rotate within the fixed frame, the cylinder fixed on the surface of the rotating rod can drive the strong magnetic rod to rotate synchronously. During the rotation, the strong magnetic rod can adsorb iron impurities in the placement frame, achieving the purpose of removing iron impurities in all directions. Attached Figure Description

Detailed Implementation

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a rotary iron removal device for silica production, including a base plate 1, a support platform 2 fixedly installed on the top of the base plate 1, a groove 3 formed in the support platform 2, a placement frame 4 fixedly installed on the top of the support platform 2, and a fixing frame 5 fixedly installed on the top of the base plate 1. A control component 6 is provided within the support platform 2 and the fixing frame 5. The control component 6 includes: a scraper ring 61, a crossbar 62, a support block 63, and a rotating component 64. When the fixing rod 649 fixed to the side of the support platform 2 abuts... When the slide bar 644 reaches the cut surface, the slide bar 644 can slide along the top of the connecting plate 642 under force. The support block 63 fixed at the bottom of the slide bar 644 can move laterally along the surface of the flat bar 641. When the support block 63 moves, the cross bar 62 fixed at the bottom of the support block 63 can drive the scraper ring 61 to slide along the surface of the strong magnetic rod 646, scraping off the iron impurities that remain on the surface of the strong magnetic rod 646, thereby achieving rapid removal of iron impurities without stopping the machine and avoiding adhesion that affects the subsequent iron removal effect.

[0023] The rotating component 64 includes a flat rod 641, which passes through and slidably connects to the support block 63. The flat rod 641 is fixedly installed on the inner wall of the connecting plate 642, ensuring the stability of the support block 63 during movement. One end of a spring 643 is fixedly connected to the inner wall of the connecting plate 642, and the other end of the spring 643 is fixedly installed on the side of the support block 63. When the support block 63 is no longer under force, it will spring up under the action of the spring 643. A sliding rod 644 is fixedly installed on the top of the support block 63. The front end of the sliding rod 644 has a triangular cross-section. When the cross-section of the sliding rod 644 is abutted, it can drive the support block 63 to slide. A connecting plate 642 is fixedly installed on the arc surface of a cylinder 645. A strong magnetic rod 646 is fixedly installed on the arc surface of the cylinder 645. The arc surface of the strong magnetic rod 646 is in contact with the inner wall of the scraper ring 61. When the cylinder 645 rotates, the strong magnetic rod 646 fixed on the surface of the cylinder 645 and the connecting plate 642 can rotate synchronously. A rotating rod 647 is fixedly installed on the top of the cylinder 645. The rotating rod 647 passes through the fixing frame 5 and is rotatably connected to the fixing frame 5. A motor 648 is fixedly installed on the top of the fixing frame 5. The output shaft of the motor 648 is fixedly connected to the rotating rod 647. When the output shaft of the motor 648 is subjected to force, it can drive the rotating rod 647 and the cylinder 645 to perform circular motion. A fixing rod 649 is fixedly installed on the side of the support platform 2. The setting of the fixing rod 649 on the side of the support platform 2 can cause the sliding rod 644 to move when it comes into contact with the tangential surface of the sliding rod 644.

[0024] In this invention, during use, the silica material is poured into two sets of placement frames 4 and spread out. Then, the motor 648 at the top of the fixing frame 5 is started. The output shaft of the motor 648 drives the rotating rod 647 to rotate. When the rotating rod 647 rotates, the cylinder 645 fixed at the bottom of the rotating rod 647 can drive the connecting plate 642 to rotate synchronously, as well as the strong magnetic rod 646 to rotate synchronously. During the rotation, the strong magnetic rod 646 can adsorb iron impurities in the placement frame 4, achieving the purpose of removing iron impurities in all directions. During the rotation of the connecting plate 642, when the fixing rod 649 fixed on the side of the support platform 2 abuts against the sliding rod 6... When the 44 section is cut, the slide bar 644 can slide along the top of the connecting plate 642 under force. The support block 63 fixed at the bottom of the slide bar 644 can move laterally along the surface of the flat bar 641. When the support block 63 moves, the cross bar 62 fixed at the bottom of the support block 63 can drive the scraper ring 61 to slide along the surface of the strong magnetic rod 646, scraping off the iron impurities that remain on the surface of the strong magnetic rod 646. This achieves rapid removal of iron impurities without stopping the machine, avoiding adhesion that affects the subsequent iron removal effect. The scraped iron impurities fall into the groove 3 in the support platform 2 for centralized collection, so that the operator can carry out subsequent processing.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
