Description

Technical Field

[0001] This application relates to the field of iron removal technology for slurry, and more specifically, to an iron removal device for silica slurry. Background Technology

[0002] Silica slurry is a mixture with certain fluidity and stability formed by dispersing silica particles in a liquid medium. During preparation, silica powder, liquid medium, and an appropriate amount of grinding balls are placed in a ball mill for ball milling. During the milling process, the impact and friction of the grinding balls break down the silica particles and uniformly disperse them in the liquid medium. In the production of silica slurry, equipment wear can lead to iron entering the slurry. In fields such as the electronics industry where high electrical performance of materials is required, iron impurities can severely affect the electrical properties of the silica slurry. Therefore, it is necessary to remove iron from the prepared silica slurry.

[0003] In existing technologies, silica slurry iron removal devices typically first use a filter screen to remove large iron particles from the slurry, and then use a strong magnet to adsorb small iron particles. However, because the filter screen and strong magnet need to be installed inside the pipeline, it is difficult to clean the iron impurities adhering to them. As the iron removal process proceeds, iron impurities continuously accumulate on the filter screen and strong magnet in the silica slurry iron removal device. If not cleaned in time, the pores of the filter screen will become blocked, leading to increased resistance to slurry passage, or even preventing normal passage. When the surface of the strong magnet is covered with excessive iron impurities, its effective adsorption area decreases, and its adsorption capacity also declines, affecting the iron removal effect of the silica slurry. Therefore, it is necessary to propose a silica slurry iron removal device to solve the above problems. Summary of the Invention

[0004] The purpose of this application is to provide a silica slurry iron removal device, which can solve the technical problems of existing silica slurry iron removal devices where the filter screen and strong magnet are installed inside the pipeline, making cleaning inconvenient. As iron removal proceeds, iron impurities continuously accumulate on both, and if not cleaned in time, the filter screen will become clogged, hindering the passage of slurry, and the adsorption capacity of the strong magnet will also decrease, affecting the iron removal effect.

[0005] This application provides an iron removal device for silica slurry, including a pipe with a filter screen inside. An opening is located on one side of the pipe, and a receiving frame is located outside the opening. A cleaning component is located above the filter screen inside the pipe. A cylinder is located on the side of the pipe opposite to the receiving frame, and the cylinder drives the cleaning component to push the iron impurities intercepted by the filter screen towards the opening. An inclined guide plate is located below the filter screen inside the pipe. A transition frame is fixed to the lower end of the guide plate outside the pipe, and the transition frame communicates with the inside of the pipe. Two strong magnets are vertically inserted into the transition frame, positioned near the side of the transition frame away from the guide plate.

[0006] Furthermore, the cleaning assembly includes a cleaning rod and a scraper. The telescopic rod of the cylinder extends into the pipe and connects to one side of the cleaning rod. The scraper is fixed to the bottom of the cleaning rod and abuts against the filter screen.

[0007] Furthermore, both ends of the cleaning rod are provided with rollers, and the inner wall of the pipe is provided with guide grooves that are adapted to the rollers, and the rollers are tumblingly connected to the guide grooves.

[0008] Furthermore, the outer wall of the pipe is provided with a snap-fit ​​component, and the receiving frame is provided with a snap-fit ​​groove that is adapted to the snap-fit ​​component. The receiving frame is snapped onto the outer wall of the pipe through the cooperation of the snap-fit ​​groove and the snap-fit ​​component.

[0009] Furthermore, a guide plate is provided within the transition frame, and the guide plate is located below the material guide plate.

[0010] Furthermore, the filter screen is provided with a fixing frame around its perimeter, and the filter screen is inserted into the pipe through the fixing frame in a pull-out manner.

[0011] Furthermore, a first sealing ring is provided at the connection between the cylinder's telescopic rod and the pipe, and a second sealing ring is provided at the connection between the fixing frame and the pipe.

[0012] The beneficial effects of this utility model are:

[0013] This invention uses a cylinder-driven cleaning assembly to push iron impurities intercepted by the filter screen to the receiving frame outside the opening. This promptly cleans the iron impurities on the filter screen, solving the problem of difficulty in cleaning the filter screen when it is installed inside the pipeline. This improves cleaning efficiency, ensures the normal filtration effect of the filter screen, and avoids increased resistance to slurry passage due to blockage. After filtration, the slurry flows to the strong magnets in the transition frame under the action of the guide plate for further iron removal. Two strong magnets are vertically inserted in the transition frame, making it easy to remove the strong magnets from the transition frame for cleaning the adsorbed iron impurities. The two strong magnets are used alternately to achieve simultaneous cleaning and adsorption, ensuring an uninterrupted iron removal process. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Specific implementation examples:

[0026] like Figure 1 and Figure 2As shown, this application provides a silica slurry iron removal device, including a pipe 1, a filter screen 2 inside the pipe 1, an opening 3 on one side of the pipe 1, a receiving frame 4 outside the opening 3, a cleaning component 5 above the filter screen 2 inside the pipe 1, a cylinder 6 on the side of the pipe 1 opposite to the receiving frame 4, the cylinder 6 driving the cleaning component 5 to push the iron impurities intercepted by the filter screen 2 towards the opening 3, an inclined guide plate 7 below the filter screen 2 inside the pipe 1, a transition frame 8 fixed at the lower end of the guide plate 7 outside the pipe 1, the transition frame 8 communicating with the inside of the pipe 1, two strong magnets 9 vertically inserted inside the transition frame 8, the strong magnets 9 being located near the side of the transition frame 8 away from the guide plate 7, specifically, both strong magnets 9 are permanent magnet plates, the silica slurry flows from top to bottom, and is initially filtered by the filter screen 2 inside the pipe 1, intercepting large iron particles, when a certain amount of iron impurities accumulate on the filter screen 2, the cylinder 6 on one side of the pipe 1 drives the cleaning component 5. The cleaning component 5 pushes the iron impurities from the filter screen 2 to the opening 3 of the pipe 1, allowing them to fall into the receiving frame 4 outside the opening 3 for easy cleaning and collection. The slurry filtered by the filter screen 2 flows into the transition frame 8 along the inclined guide plate 7 below the filter screen 2 inside the pipe 1. In the transition frame 8, the vertically inserted strong magnet 9 adsorbs the remaining small iron particles in the slurry, thus completing the iron removal operation of the silica slurry. The cleaning component 5 is driven by the cylinder 6 to push the iron impurities intercepted by the filter screen 2 to the receiving frame 4 outside the opening 3, which can clean the iron impurities on the filter screen 2 in time, solving the problem that it was difficult to clean the filter screen 2 because it was installed inside the pipe 1. This improves the cleaning efficiency, ensures the normal filtration effect of the filter screen 2, and avoids the increase in slurry resistance due to blockage. The two strong magnets 9 are vertically inserted in the transition frame 8, which makes it easy to remove the strong magnets 9 from the transition frame 8 for cleaning the adsorbed iron impurities. The two strong magnets 9 are used alternately to achieve simultaneous cleaning and adsorption, ensuring that the iron removal process is uninterrupted.

[0027] like Figure 2 As shown, the cleaning assembly 5 includes a cleaning rod 51 and a scraper 52. The telescopic rod of the cylinder 6 extends into the pipe 1 and is connected to one side of the cleaning rod 51. The scraper 52 is fixed to the bottom of the cleaning rod 51 and abuts against the filter screen 2. When the telescopic rod of the cylinder 6 pushes the cleaning rod 51 to move, the cleaning rod 51 drives the scraper 52 to scrape off the iron impurities intercepted on the filter screen 2.

[0028] like Figure 2As shown, both ends of the cleaning rod 51 are equipped with rollers (not shown in the figure), and the inner wall of the pipe 1 is provided with guide grooves 10 that are adapted to the rollers. The rollers and guide grooves 10 are in rolling connection. The cooperation between the rollers and guide grooves 10 helps the cleaning rod 51 maintain stable movement during movement. The rollers and guide grooves 10 are in rolling connection. Compared with sliding friction, rolling friction has less friction. On the one hand, it reduces the wear of the cleaning rod 51 and the inner wall of the pipe 1, and extends the service life of the device. On the other hand, the smaller friction makes the force required for the cylinder 6 to push the cleaning rod 51 smaller, reducing energy consumption and improving the energy utilization efficiency of the equipment. It also helps to improve the working efficiency and stability of the cylinder 6.

[0029] like Figure 2 As shown, the outer wall of the pipe 1 is provided with a snap-fit ​​part 11, and the receiving frame 4 is provided with a snap-fit ​​groove 41 that is adapted to the snap-fit ​​part 11. The receiving frame 4 is snapped onto the outer wall of the pipe 1 through the cooperation of the snap-fit ​​groove 41 and the snap-fit ​​part 11. When the receiving frame 4 is filled with iron impurities, it is easy to remove the receiving frame 4 and process the iron impurities in the receiving frame 4.

[0030] like Figure 2 As shown, a guide plate 12 is provided inside the transition frame 8. The guide plate 12 is located below the guide plate 7. It can further guide the silica slurry that flows into the transition frame 8 after being guided by the guide plate 7. It can ensure that the slurry flows to the area where the strong magnet 9 is located in a predetermined direction and path, so that the slurry can contact the strong magnet 9 more fully, thereby improving the adsorption efficiency of the strong magnet 9 on small iron impurities in the slurry.

[0031] like Figure 1 and Figure 2 As shown, the filter screen 2 is equipped with a fixing bracket 13 around its perimeter. The filter screen 2 is installed in the pipe 1 by being pulled out through the fixing bracket 13, making the installation process simple and direct. The pull-out design makes it easy to remove the filter screen 2 from the pipe 1 for comprehensive and meticulous maintenance and cleaning. In addition to daily cleaning of iron impurities on the surface by the cleaning component 5, the filter screen 2 can be pulled out periodically for deep cleaning of all parts, especially the inside of the mesh, to ensure that the filtration effect is always good.

[0032] like Figure 2 As shown, a first sealing ring 14 is provided at the connection between the telescopic rod of cylinder 6 and pipe 1, and a second sealing ring (not shown in the figure) is provided at the connection between the fixed frame 13 and pipe 1. During the operation of the iron removal device, the slurry flows in pipe 1. Through the design of the first sealing ring 14 and the second sealing ring, it is ensured that the slurry will not leak to the outside of the device, thus avoiding slurry waste, pollution of the working environment, and ensuring the normal operation of the equipment.

[0033] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
