Description

Technical Field

[0001] This utility model belongs to the technical field of refractory brick production equipment, specifically a feeding device for refractory brick production. Background Technology

[0002] Refractory bricks, as an essential material in industry and daily life, involve several key steps in their manufacturing process. First, high-quality raw materials must be carefully selected and calcined at high temperatures to remove impurities and enhance refractoriness. Next, the raw materials are graded to ensure consistent quality. Next, crushing and grinding are crucial steps, ensuring uniform particle size and laying the foundation for subsequent molding. Scientific batching and mixing of the raw materials ensure material homogeneity and stability. Forced molding is a critical step determining the density and strength of the brick blank, directly affecting the performance of the final product. After molding, the bricks need to be allowed to dry and then fired at high temperatures to further improve their refractoriness. Finally, after exiting the kiln, strict quality inspection, packaging, and loading are conducted before shipment. Throughout the entire process, crushing, grinding, and forced molding are particularly critical, directly impacting the quality and application performance of the refractory bricks.

[0003] Currently, various methods have been proposed for feeding equipment in refractory brick production. For example, a patent application with publication number "CN221338949U" discloses a feeding device for refractory brick production. The device is quickly and stably installed at the feeding station using external bolts via a mounting base. Then, an appropriate amount of scientifically proportioned refractory brick raw materials are fed in through the inlet, and a measured amount of clean water is injected through the water inlet pipe. The operator then controls the motor to operate, causing the output shaft to rotate and drive the spiral stirring shaft. This centrifugally stirs the refractory brick raw materials at the center of the mixing drum. During the stirring process, the spiral stirring shaft drives the rotating support rod and the small spiral stirring shaft to revolve around the central axis of the spiral stirring shaft, thus stirring the refractory brick raw materials at the inner edge of the mixing drum. However, during the stirring process, the refractory brick raw materials after the water injection tend to adhere to the inner wall of the mixing drum, resulting in material waste and, when stirring different refractory brick raw materials later, causing mixing of different materials and affecting product quality.

[0004] Therefore, this utility model provides a feeding device for refractory brick production. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5 As shown in the figure, a feeding device for refractory brick production according to an embodiment of the present invention includes a mixing drum 1. A mixing rod 16 is rotatably connected inside the mixing drum 1. A mixing bar 17 is fixedly connected to the mixing rod 16. Scrapers 24 are fixedly connected to both sides of the mixing bar 17. The scrapers 24 slide against the inner wall of the mixing drum 1. A cleaning mechanism for cleaning the mixing bar 17 is installed on the mixing drum 1. A baffle 8 is rotatably connected to the upper end of the mixing drum 1. A handle 13 is fixedly connected to the upper end of the baffle 8. The baffle 8 communicates with the mixing drum 1. A feed box 7 is communicated to the upper end of the mixing drum 1. A striking mechanism for striking the side wall of the feed box 7 is installed on the mixing drum 1. A drive gear 18 is rotatably connected to the upper end of the mixing drum 1. The drive gear 18 is fixedly connected to the mixing rod 16. During operation, the refractory brick raw materials are placed into the mixing drum 1 through the feed box 7. The motor 10 is started, and the motor 10 drives the stirring rod 16 to rotate. The stirring rod 16 drives the stirring bar 17 to rotate, thus stirring the refractory brick raw materials in the mixing drum 1. At the same time, the scraper 24 slides against the inner wall of the mixing drum 1 to scrape off the raw materials adhering to the inner wall, ensuring that the raw materials are fully mixed and not wasted.

[0026] like Figure 1 and Figure 4 As shown, a motor frame 9 is fixedly connected to the upper end of the stirring drum 1, and a motor 10 is fixedly connected to the upper end of the motor frame 9. The output shaft of the motor 10 is fixedly connected to the drive gear 18. During operation, the motor 10 is started, and the motor 10 drives the stirring rod 16 to rotate. Through the above structure, the motor 10, as a power source, drives the drive gear 18 to rotate through the output shaft, thereby driving the stirring rod 16 to rotate, realizing the full automation of the stirring process. This not only reduces manual intervention and lowers labor costs, but also improves production efficiency, enabling the equipment to operate continuously and stably.

[0027] like Figure 1As shown, the cleaning mechanism includes a fixed plate 2, a water bucket 3, a water spray pipe 4, and a water pump 12. The fixed plate 2 is fixedly installed on the side wall of the mixing drum 1, the water bucket 3 is fixedly installed on the upper end of the fixed plate 2, the water pump 12 is located inside the water bucket 3, and the water spray pipe 4 is located above the water pump 12. During operation, the water pump 12 is activated to spray the cleaning water in the water bucket 3 onto the surfaces of the mixing rod 17 and the scraper 24 through the water spray pipe 4. Through this structure, the cleaning mechanism effectively removes refractory brick raw materials adhering to these components by spraying the cleaning water in the water bucket 3 onto the surfaces of the mixing rod 17 and the scraper 24 through the water spray pipe 4. This cleaning method is not only thorough but can also be performed quickly between different batches of raw materials, avoiding cross-contamination and ensuring consistent product quality.

[0028] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the striking mechanism includes a U-shaped frame 19, a striking plate 20, a short rod 21, and a push plate 23. The U-shaped frame 19 is fixedly installed on the side wall of the feed box 7. The short rod 21 is slidably installed on the side wall of the U-shaped frame 19. The striking plate 20 is fixedly installed on one end of the short rod 21, and the push plate 23 is fixedly installed on the other end of the short rod 21. A reset mechanism for resetting the short rod 21 is installed on the U-shaped frame 19, and a moving mechanism for moving the push plate 23 is installed on the stirring drum 1. During operation, the driving gear 18 drives the driven gear 14 to rotate. The driven gear 14 drives the cam 11 to rotate through the rotating rod 15. When the cam 11 contacts the push plate 23, the cam 11 presses the push plate 23, causing the push plate 23 to move the short rod 21, thereby causing the striking plate 20 to strike the side wall of the feed box 7. At this time, the spring 22 is compressed. When the cam 11 is not in contact with the push plate 23, the spring 22 resets, thereby causing the 20 to move back to its original position. With the above structure, the striking mechanism taps the side wall of the feed box 7, allowing the raw materials to enter the mixing drum 1 evenly. This design avoids problems such as blockage or uneven distribution of raw materials during the feeding process, ensuring the smooth progress of the mixing process and improving the utilization rate of raw materials and product quality.

[0029] like Figure 5 As shown, the reset mechanism includes a spring 22, one end of which is fixedly mounted on the side wall of the U-shaped frame 19, and the other end of which is fixedly mounted on the short rod 21. Through this structure, the spring 22 in the reset mechanism ensures that the short rod 21 and the striking plate 20 quickly reset after each strike, guaranteeing the continuity and stability of the striking action. This design enables the striking mechanism to operate stably for extended periods, reducing downtime due to mechanical failures and improving equipment reliability.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the moving mechanism includes a driven gear 14, a rotating rod 15, and a cam 11. The driven gear 14 is rotatably mounted on the upper end of the stirring drum 1 and meshes with the driving gear 18. The rotating rod 15 is fixedly mounted on the upper end of the driven gear 14, and the cam 11 is fixedly mounted on the upper end of the rotating rod 15. During operation, the motor 10 drives the driving gear 18 to rotate, the driving gear 18 drives the driven gear 14 to rotate, and 14 drives 11 to rotate via 15.

[0031] like Figure 1 As shown, three fixed columns 5 are fixedly connected to the lower end of the mixing drum 1, and a discharge pipe 6 is connected to the lower end of the mixing drum 1. A solenoid valve is installed inside the discharge pipe 6. Through this structure, the discharge pipe 6 and the solenoid valve make the discharge process more controllable. The solenoid valve allows for precise control of the discharge time and speed, avoiding waste of raw materials and ensuring the continuity of the production process. This design improves the automation level of the equipment and reduces errors from manual operation.

[0032] Working principle: Refractory brick raw materials are placed into the mixing drum 1 through the feed box 7. The motor 10 is started, which drives the stirring rod 16 to rotate. The stirring rod 16 drives the stirring bar 17 to rotate, thus stirring the refractory brick raw materials in the mixing drum 1. At the same time, the scraper 24 slides against the inner wall of the mixing drum 1, scraping off the raw materials adhering to the inner wall, ensuring that the raw materials are fully mixed and not wasted. Meanwhile, the motor 10 drives the drive gear 18 to rotate, which drives the driven gear 14 to rotate. The driven gear 14 drives the cam 11 to rotate through the rotating rod 15. When the cam 11 contacts the push plate 23, the cam 11 presses the push plate 23, causing the push plate 23 to drive the short rod 21 to move, which in turn causes the striking plate 20 to strike the side wall of the feed box 7. At this time, the spring 22 is compressed. When the cam 11 is no longer in contact with the push plate 23, the spring 22 returns to its original position, thus causing the cam 20 to move back to its original position.

[0033] When cleaning of the parts inside the mixing drum 1 is required, pull handle 13 to rotate and open baffle 8, start water pump 12 to spray cleaning water from water tank 3 through water spray pipe 4 onto the surface of mixing rod 17 and scraper 24, cleaning the attached raw materials and preventing mixing of different batches of raw materials. After mixing is completed, the refractory brick raw materials are discharged through discharge pipe 6, and the discharge process is controlled by solenoid valve.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
