Description

Technical Field

[0001] This utility model relates to material handling technology, and in particular to a system for crushing crusted material. Background Technology

[0002] In industrial production, the efficiency and stability of the material conveying system directly affect the overall production line's capacity and cost control. However, traditional material conveying systems are somewhat inadequate when dealing with the problem of caking material in silos. Caking material mainly forms because, during long-term storage or transportation, factors such as moisture, pressure, and temperature changes cause material particles to stick together, gradually forming a hard, blocky structure. This caking material not only hinders the normal flow of materials and reduces production efficiency but can also damage conveying equipment, leading to production line shutdowns and significant economic losses for the company.

[0003] Initially, the removal of crusted material relied mainly on manual labor, which was not only time-consuming and labor-intensive, but also difficult to achieve a thorough clean. With technological advancements, mechanical crushing equipment began to be used for crust removal, typically employing rotating blades and impact hammers to break up the crusted material. While this method improved cleaning efficiency to some extent, mechanical crushing equipment is generally complex in structure and has high maintenance costs.

[0004] Therefore, there is an urgent need for a simple pneumatic crushing structure for crushing crusted materials. Utility Model Content

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1: A system for breaking up crusted material, such as Figure 1 and Figure 3As shown, the system includes a protective cover 1, a hopper 2, a frame 3, a support plate 4, a screw feeder 5, a nozzle 6, an air outlet pipe 7, an air cannon 8, a pulse valve 9, and an air inlet pipe 10. The hopper 2 is mounted on the upper part of the frame 3. During material transport, a large amount of sludge will form in the hopper 2, causing blockages. To ensure continuous feeding, the sludge needs to be broken up. A protective cover 1 is movably mounted on the top of the hopper 2. The protective cover 1 is used to close and protect the opening of the hopper, preventing external impurities from entering. A support plate 4 is located in the middle of the frame 3. An air cannon 8 is mounted on the right side of the support plate 4. The air cannon 8 uses aerodynamic principles to release compressed gas to generate shock waves and high-speed airflow, thereby effectively eliminating material blockages and breaking up the material. A pulse valve 9 is mounted at the bottom of the air cannon 8. The pulse valve 9 is a valve that controls the gas flow and is usually used in conjunction with the air cannon 8. An air inlet pipe 10 is connected to the lower right side of the air cannon 8. The air pipe 10 provides sufficient gas supply to the air cannon 8 to generate sufficient shock waves and high-speed airflow. The top of the air cannon 8 is connected to the air outlet pipe 7, which runs through one side of the hopper 2. The end of the air outlet pipe 7 is connected to the nozzle 6. The nozzle 6 is used to guide the high-speed airflow generated by the air cannon 8 to the outlet of the hopper 2, break up the scabbed material to clear the blockage, and realize the directional injection of gas. The lower part of the support plate 4 is provided with a screw feeder 5, which is located directly below the outlet of the hopper 2. Through the rotation of the screw blades, the material is pushed and conveyed to realize the continuous and uniform conveying of the material.

[0021] During material conveying, scabs accumulate in hopper 2. Since the scabs are large, hard pieces, they can clog the outlet. It is necessary to break up the scabs. At this time, the compressed air source is connected to the air inlet pipe 10, and then the pulse valve 9 is turned to allow compressed air to be delivered to the air cannon 8. The compressed air releases energy instantly, forming a high-speed airflow. The airflow is then delivered to the nozzle 6 through the air outlet pipe 7, and the high-speed airflow is precisely sprayed onto the scabs at the outlet. The huge energy carried by the high-speed airflow can directly act on the scabs, producing a strong impact and scouring effect, which quickly breaks up the hard scabs and restores their original fluidity. Then, the broken material is evenly sent to the subsequent processing area by the screw feeder 5.

[0022] Example 2: Based on Example 1, such as Figure 2 and Figure 4As shown, it also includes a motor 11, a transmission gear 12, a protective shell 1201, a driven gear 13, a connecting rod 14, a stirring rod 15, and a soft brush 16. The protective shell 1201 is located on the right side of the support plate 4. The transmission gear 12 is rotatably mounted on the support plate 4 and is located inside the protective shell 1201. The motor 11 is mounted on the protective shell 1201, and the output shaft of the motor 11 passes through the top of the protective shell 1201 and connects to the transmission gear 12. The driven gear 13 is rotatably mounted in the middle of the support plate 4 and meshes with the transmission gear 12. A material drop hole is provided in the middle of the driven gear 13. The hopper 2 is connected to the screw feeder 5 through the material drop hole of the driven gear 13. A connecting rod 14 is welded to the driven gear 13. The upper part of the connecting rod 14 is parallel to the lower inner wall of the hopper 2. Multiple evenly spaced parts are installed on the inner side of the connecting rod 14. A stirring rod 15 and a soft brush 16 are installed on the outside of the connecting rod 14. The motor 11 drives the transmission gear 12 and the driven gear 13 to rotate, which in turn drives the connecting rod 14 and the stirring rod 15 and soft brush 16 to rotate stably. The soft brush 16 is made of a material with a certain degree of flexibility and wear resistance. Driven by the connecting rod 14, the soft brush 16 closely adheres to the inner wall of the hopper 2, gently and effectively cleaning the loose, poorly attached scabs and residual materials, preventing secondary agglomeration. The multiple stirring rods 15 on the inner side of the connecting rod 14 are made of rigid material. During rotation, they can penetrate into the material accumulation area to pre-break up any potential agglomeration problems, preventing the formation of new large scabs, further ensuring the smoothness of material conveying, and comprehensively addressing the scab problem in the hopper 2, ensuring the stable and efficient operation of the subsequent material conveying system.

[0023] When it is necessary to treat loose, poorly adhered scabs and residual materials on the inner wall of hopper 2 to prevent secondary clumping, motor 11 is started. Motor 11 drives transmission gear 12 to rotate through output shaft, thereby driving driven gear 13 and its connected connecting rod 14 to rotate. This causes stirring rod 15 to rotate and initially disperse the material in hopper 2, uniformly stirring and effectively crushing the material. At the same time, it breaks down the adhesion and friction between materials, making it easier for the material to flow in hopper 2, improving the processing efficiency and quality of the material. Meanwhile, soft brush 16 moves closely to the inner wall of hopper 2 with connecting rod 14, effectively cleaning the scabs and residues attached to the wall surface.

It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
