Abstract
Description
Technical Field
[0001] This utility model relates to the field of crushing equipment technology, and in particular to a dry vibrating material crushing equipment. Background Technology
[0002] In industries such as metallurgy and building materials, dry vibratory mixes, as important unshaped refractory materials, are widely used in the lining construction of high-temperature furnaces and kilns. The crushing quality of the raw materials directly affects the performance and service life of the dry vibratory mix, and thus the operational stability and safety of furnaces and other equipment. However, traditional dry vibratory mix raw material crushing equipment has many problems in practical applications. On the one hand, most crushing equipment uses a single crushing structure, making it difficult to accurately control the particle size of the raw materials, resulting in uneven particle size after crushing. This fails to meet the strict particle size requirements of dry vibratory mixes, reducing product quality. On the other hand, dry vibratory mix raw materials easily generate a large amount of dust during the crushing process. Traditional crushing equipment lacks effective dust control measures, resulting in serious dust overflow, which not only pollutes the production environment but also poses a great threat to the health of operators. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a dry vibrating material crushing equipment, which has the advantages of achieving precise particle size control, continuous production, and good dust prevention, thus solving some of the problems mentioned in the background technology.
[0004] This utility model provides the following technical solution: a dry vibrating material crushing device, including a double-toothed roller crusher and a return plate. A screw conveyor is fixedly installed and connected to the upper end of the double-toothed roller crusher, and a screw conveyor is fixedly installed and connected to the lower end of the double-toothed roller crusher. A discharge port is provided inside the return plate at the lower end of the screw conveyor. A drive shaft is rotatably installed through the middle of the return plate. A drive plate is fixedly sleeved on the right end of the drive shaft. Two sets of symmetrical scrapers are slidably connected inside the return plate. A connecting rod is fixedly connected to the middle of the right end of each scraper. An annular groove is provided on the right end of the return plate. The scrapers are fixedly connected to the drive plate through the annular groove via connecting rods. A return port is provided inside the return plate at the upper end of the screw conveyor.
[0005] Furthermore, the upper end of the first screw conveyor is provided with a feeding port near the left side, and the lower end of the second screw conveyor is provided with uniformly distributed screen bars corresponding to the double toothed roller crusher. There is a certain gap between the screen bars, and the round shape of the screen bars is conducive to promoting the raw materials that meet the particle size requirements to fall through the gap.
[0006] Furthermore, the return plate is fixedly mounted on the outer wall of screw conveyor one and screw conveyor two near the right side. The openings of the discharge port and the return port both penetrate the inner ring of the return plate and fit together, thus avoiding structural conflicts that could affect the movement of the scraper.
[0007] Furthermore, a driven gear is fixedly sleeved on the left end of the drive shaft, and a main roller shaft core passes through the right end of the double-toothed roller crusher. A main gear is fixedly sleeved on the main roller shaft core at the corresponding driven gear position. The main gear and the driven gear are meshed together. Double bearing seat assemblies are fixedly sleeved on both the left and right sides of the main gear between the main roller shaft core and the drive shaft. The connection strength between the structures is improved by the double bearing seat assemblies.
[0008] Furthermore, retaining ring plates are fixedly connected to both the front and rear ends of the transmission plate near the upper and lower sides. The retaining ring plates are adapted to the annular groove to improve the sealing performance of the return material tray.
[0009] Furthermore, a dust cover is fixedly installed at the lower end of the screw conveyor second on the outside of the screening rod. A movable collection box is placed on the lower side of the dust cover. The movable collection box fits into the dust cover and is pushed from the left side of the device.
[0010] The advantages of this utility model are as follows:
[0011] 1. Through the coordinated operation of screw conveyor one, double toothed roller crusher and screw conveyor two, the raw material is continuously crushed and circulated. After being screened by the screening bar, only the raw material that meets the particle size requirements can enter the collection box, which effectively ensures the precise control of the particle size of the crushed raw material. At the same time, the whole process realizes continuous operation without frequent shutdowns, which greatly improves production efficiency and reduces labor costs and equipment wear.
[0012] 2. The equipment adopts multiple dust prevention measures in its structural design. The screw conveyor one and screw conveyor two seal the upper and lower openings of the double toothed roller crusher, and the baffle plate always covers the ring groove. Together with the dust cover that matches the opening of the movable collection box, it effectively prevents the large amount of dust generated during the raw material crushing process from overflowing, avoiding environmental pollution and harm to the health of operators.

The lower end of the screw conveyor 3 has uniformly distributed screen rods 6 corresponding to the double toothed roller crusher 1. There is a certain gap between the screen rods 6. Raw materials are added through the feeding port 5. Opening the screw conveyor 2 allows the raw materials to enter the double toothed roller crusher 1 through its interior, while also preventing blockage. Opening the double toothed roller crusher 1 allows the teeth inside to... The rollers, in conjunction with the inner liner, crush the raw material. The crushed material falls into the screw conveyor 3. Opening the screw conveyor 3 allows the crushed material to be conveyed to the right. Simultaneously, material meeting the particle size requirements for vibrating feed will fall into the movable collection box 19 through the gap of the screen rod 6 during the conveying process. The crushed material conveyed to the right will eventually enter the return plate 4 through the discharge port 7. The rotation of the drive shaft 8 can drive the drive plate 9 to rotate. The rotation of the drive plate 9 can drive the connecting rod 12 to rotate the scraper 10. The scraper 10 then moves the material through the return plate 4. The internal rotation of the device can drive the crushed raw material entering it to the return port 13, and then, under the action of gravity, it enters the screw conveyor 2 through the return port 13. Then, driven by the screw blades in the screw conveyor 2, it is conveyed to the left and enters the double toothed roller crusher 1 again for secondary crushing. This process is repeated until the raw material that meets the particle size requirements enters the movable collection box 19 through the screen rod 6 and is collected, thus ensuring the quality requirements of the product. Moreover, this device can meet the needs of continuous production and is suitable for the production of vibrating materials of different scales, ensuring both quality and quantity.
[0021] Please see Figure 3The upper end of the screw conveyor 2 has a feeding port 5 near the left side. The return plate 4 is fixedly fitted onto the outer wall of the screw conveyor 2 and the screw conveyor 3 near the right side. The openings of the discharge port 7 and the return port 13 both penetrate the inner ring of the return plate 4 and fit together. The lower end of the screw conveyor 3 has a dust cover 20 fixedly installed on the outside of the screening rod 6. A movable collection box 19 is placed on the lower side of the dust cover 20, and the movable collection box 19 fits into the dust cover 20. The front and rear ends of the transmission plate 9 are near the upper and lower sides. Each side is fixedly connected with a baffle plate 18, which is adapted to fit the annular groove 11. This device seals the upper and lower openings of the double toothed roller crusher 1 through the screw conveyor 2 and the screw conveyor 3. The baffle plate 18 can always cover the annular groove 11. In addition, through the design of the dust cover 20 and its fit with the opening of the movable collection box 19, a large amount of dust generated during the crushing process is ideally prevented from directly entering the air, thus avoiding harm to the environment and the health of operators.
[0022] Please see Figure 4 The left end of the drive shaft 8 is fixedly sleeved with a driven gear 14, and the right end of the double toothed roll crusher 1 is through a main roller shaft core 15. A main gear 16 is fixedly sleeved on the main roller shaft core 15 at the corresponding position of the driven gear 14. The main gear 16 and the driven gear 14 are meshed and connected. Double bearing housing assemblies 17 are fixedly sleeved on both the left and right sides of the main gear 16 between the main roller shaft core 15 and the drive shaft 8. When the double toothed roll crusher 1 is running, the main roller shaft core 15 will drive the main gear 16 to rotate at the same time. The rotation of the main gear 16 can drive the driven gear 14 to rotate the drive shaft 8.
[0023] Working Principle: Raw materials are added through the feed port 5. Opening the screw conveyor 2 allows the raw materials to enter the double toothed roller crusher 1 through its interior, while also preventing blockage. Opening the double toothed roller crusher 1 allows the toothed rollers inside to crush the raw materials in conjunction with the inner liner plate. The crushed raw materials fall into the screw conveyor 3. Opening the screw conveyor 3 allows the crushed raw materials to be conveyed to the right. At the same time, raw materials that meet the particle size requirements of vibrating material will fall into the movable collection box 19 through the gap of the screen rod 6 during the conveying process. The crushed raw materials conveyed to the right will finally enter the return plate 4 through the discharge port 7. When the double toothed roller crusher 1 is running, the main roller shaft core 15 will simultaneously drive the main gear 16 to rotate. The rotation of the main gear 16 will drive the driven gear 14 to rotate the transmission shaft 8. The rotation of the transmission shaft 8 will drive the transmission plate 9 to rotate. The rotation of the transmission plate 9 will drive the connecting rod 12 to rotate the scraper 10. The rotation of the scraper 10 inside the return plate 4 will cause the raw materials to be crushed. The crushed raw material inside is carried to the return port 13, and then enters the screw conveyor 2 under gravity. Driven by the screw blades inside the screw conveyor 2, it is conveyed to the left and re-enters the double-toothed roller crusher 1 for secondary crushing. This process is repeated until the raw material meeting the particle size requirements is collected in the movable collection box 19 through the screen rod 6, thus ensuring product quality. This device can meet the needs of continuous production and is suitable for the production of vibrating materials of different scales, ensuring both quality and quantity. Furthermore, the device seals the upper and lower openings of the double-toothed roller crusher 1 through the screw conveyor 2 and screw conveyor 3. The baffle plate 18 can always shield the annular groove 11. In addition, the dust cover 20 is designed to fit the opening of the movable collection box 19, effectively preventing a large amount of dust generated during the crushing process from directly entering the air, thus avoiding harm to the environment and the health of operators.
