Description

Technical Field

[0001] This invention relates to the field of steel production technology, specifically to a method for manufacturing a high-strength pellet binder. Background Technology

[0002] Pellet binders are key chemical additives used to bind raw materials such as iron concentrate and steel slag powder into pellets. However, existing pellet binders may not meet the strength and durability requirements in certain applications.

[0003] Referring to a Chinese patent, "An Oxidized Pelletizer Made from Low-Rank Coal, Its Preparation Method and Application" (Publication No.: CN111254278A, Publication Date: 2020-06-09), this patent solves the problems of increased gangue content, decreased iron grade, increased energy consumption in steel production, and the inability to use bentonite binders for pelletizing some low-quality iron ore resources due to the addition of bentonite in the existing iron ore pelletizing process. However, existing pellet binders still have the following shortcomings in the manufacturing process:

[0004] (1) The binder mixture needs to be ground before aging. Since the fine powder and solid particles in the mixture have different particle sizes, during the feeding process, the larger particles are prone to settle to the bottom of the feed hopper. These particles are large in size and can easily block the feed inlet, resulting in slow feeding. Moreover, the large particles enter the grinding equipment first and the small particles enter the grinding equipment later. The grinding time required before and after is different, which makes it inconvenient to control the overall grinding time and makes it easy to make the grinding effect unsatisfactory.

[0005] (2) Fine powder in the mixture is easy to remain on the inner wall of the feed hopper, which not only wastes materials, but also makes it difficult to scrape off the dried powder, thus polluting the inside of the hopper.

[0006] To address this problem, we propose a method for manufacturing a high-strength pellet binder. Summary of the Invention

[0021] Beneficial effects

[0022] This invention provides a method for manufacturing a high-strength pellet binder. Compared with the prior art, it has the following advantages:

[0023] (1) The manufacturing method of this high-strength pellet binder, through the setting of an automated stirring and pushing mechanism, realizes the up-and-down full stirring of the mixture at different depths in the feed hopper, so that the fine powder and solid particles in the mixture can be uniformly mixed, avoiding the sedimentation of larger particles to the bottom of the feed hopper, causing blockage of the feed inlet. At the same time, after the mixture is uniformly mixed, particles of different sizes can be uniformly entered into the ball mill for grinding, which makes it easy to control the grinding time and effectively improves the grinding effect.

[0024] (2) The manufacturing method of this high-strength pellet binder, through the setting of the scraping component, cooperates with the automated mixing and pushing mechanism. During the up-and-down reciprocating work of the automated mixing and pushing mechanism, the scraper one, scraper two and brush on the scraping component can move up and down and scrape the fine powder remaining on the inner wall of the feed hopper. This not only avoids material waste, but also avoids contamination of the inside of the feed hopper. It is linked with the automated mixing and pushing mechanism and has a high degree of automation.

[0025] (3) The manufacturing method of this high-strength pellet binder is to use an automated feeding component to push the powder deposited on the bottom wall of the receiving box to one side by using a cylinder to drive the pusher plate. When the mixture needs to be aged, the mixture is then extracted by a pump, so that the deposited powder can be well extracted by the pump, ensuring the concentration of the mixture and further ensuring the viscosity of the binder after aging.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] The present invention provides three technical solutions, specifically including the following embodiments:

[0036] Example 1

[0037] A method for manufacturing a high-strength pellet binder specifically includes the following steps:

[0038] Step 1: Take a crucible, pour in deionized water, then pour in polyvinyl alcohol powder, stir for 3-5 minutes, then add epoxy resin and vulcanizing agent. Epoxy resin is a commonly used crosslinking agent used to prepare epoxy adhesives. They need to react with hardeners (such as amine compounds) to form a strong three-dimensional network structure. Vulcanizing agents are hardening catalysts that can initiate or promote crosslinking reactions between polymers. Continue stirring for 1-2 minutes. The weight ratio of each raw material is as follows: polyvinyl alcohol 20-30 parts, epoxy resin 25-35 parts, vulcanizing agent 10-20 parts, deionized water 40-50 parts.

[0039] Step 2: Using heating equipment, heat the mixture in the crucible to 80-90℃, and continue stirring the mixture for 3-4 hours.

[0040] Step 3: Stop heating and cool the mixture to room temperature. During cooling, add quartz powder, aluminum powder, polytetrafluoroethylene (PTFE) particles, and alkylbenzene sulfonate in sequence. Quartz powder, aluminum powder, and PTFE particles are inorganic fillers. Inorganic fillers in binders can improve properties such as hardness, stability, and chemical resistance, and adjust thermal and electrical conductivity to meet different application requirements. Alkylbenzene sulfonate is a dispersant, a chemical substance used to uniformly disperse solid particles in a liquid. It helps prevent particles from depositing or agglomerating in the liquid, ensuring that the particles are uniformly dispersed in the binder. Continue stirring for 20-30 minutes. The weight ratio of each raw material is: quartz powder 10-15 parts, aluminum powder 10-20 parts, PTFE particles 20-30 parts, and alkylbenzene sulfonate 20-30 parts. The use of inorganic fillers and dispersants can significantly enhance the mechanical properties of the binder, such as hardness and strength, improve stability, improve thermal and electrical conductivity, and enhance chemical resistance. This makes the binder suitable for a wider range of applications, meeting different engineering and industrial needs.

[0041] Step 4: Transfer the mixture to the grinding equipment, start the equipment to grind the mixture, and control the grinding time to 30-40 minutes;

[0042] Step 5: Place the obtained adhesive in an aging chamber for aging treatment. The ambient temperature should be controlled at 20-25℃, and the aging time should be controlled at 8-10 hours.

The brush bristles 156 are connected to the feed hopper 13. The inner wall is fitted together. Through the setting of the scraping component 15, it cooperates with the automatic mixing and pushing mechanism 14. During the up-and-down reciprocating work of the automatic mixing and pushing mechanism 14, it can drive the scraper 154, scraper 155 and brush 156 on the scraping component 15 to move up and down, and scrape the fine powder remaining on the inner wall of the feed hopper 13. This not only avoids material waste, but also avoids contamination of the inside of the feed hopper 13. It is linked with the automatic mixing and pushing mechanism 14 and has a high degree of automation.

[0050] The automated material suction assembly 11 includes a suction pump 111 fixed to one side of the receiving box 10.

[0051] Example 3

[0052] This embodiment is obtained by combining Embodiment 1 and Embodiment 2, see [link / reference]. Figure 1 - Figure 7As shown, during operation, the adhesive mixture is poured into the feed hopper 13, and the second motor 145 is started, causing the second motor 148 to drive the rotating plate 149 and the connecting column 1410 to rotate circumferentially. The connecting column 1410 drives the T-shaped frame 145 and the slider 144 to move up and down reciprocally. The slider 144 drives the rack 1415, the rotating rod 1418, and the drive gear 1419 to move up and down synchronously. During the downward movement of the rack 1415, the moving block 1414 slides down along the inclined rod 1413. The moving block 1414 drives the rack 1415 to slide to the right. The rack 1415 drives the drive gear 1419 to rotate. The drive gear 1419 drives the rotating rod 1418 and the stirring paddle 1420 to rotate. The stirring paddle 1420 is used to stir the mixture at different depths. At the same time, the pusher column 1421 moves downward to push the material quickly. During the up-and-down reciprocating process of the automated stirring and pushing mechanism 14, the brush bristles 156 on the scraping assembly 15 are driven to scrape and clean the fine powder remaining on the inner wall of the feed hopper 13. The mixture is then fed into the ball mill 2 for grinding via the screw conveyor 5 and discharged through the discharge pipe 4 and the drop pipe 9. After falling into the receiving box 10, the cylinder 114 is activated, which drives the pusher plate 115 to push the powder on the bottom wall of the receiving box 10 to the right. The pump 111 is then activated to extract the mixture for the next aging step.
