Description

Technical Field

[0001] This utility model relates to the field of silo structure technology, and in particular to a mineral material anti-sticking feeding silo. Background Technology

[0002] Mineral materials refer to processed ores, commonly used in construction and engineering. They include natural metallic minerals (such as bauxite and iron ore) and non-metallic minerals (such as kaolin and quartz). Mineral materials play a crucial role in cement concrete or asphalt mixtures, typically requiring the blending of aggregates of different particle sizes to meet engineering design requirements. Mineral materials are characterized by their diversity, large reserves, and low price, leading to their widespread application across various fields. However, in the current non-ferrous smelting industry, wet concentrates are transported via multiple conveyor belts, passing through various transfer silos. During long-term loading, the damp and highly corrosive wet concentrates easily corrode the metal silo walls, causing material to adhere and caking, affecting material flow and stable system production. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a mineral feed silo with anti-sticking properties. This solves the technical problem that during long-term feeding of minerals, wet and highly corrosive concentrates can easily corrode the inner wall of the metal silo, causing the material to stick and clump together on the inner wall of the silo, which affects the feeding and stable production of the system.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A mineral material anti-sticking feeding silo includes: a silo body, an ultra-high molecular weight polyethylene (UHMWPE) liner, a vibrating device, a gate valve, and an air cannon. The UHMWPE liner is fitted onto the inner wall of the silo body, the gate valve is located at the bottom of the silo body, and the opening of the gate valve is adjusted to regulate the amount of material conveyed. The vibrating device and the air cannon are respectively located on the outer wall of the silo body, and a support plate is provided on the top outer wall of the silo body.

[0005] The bottom of the silo body is provided with an installation plate. The thickness of the silo body is 10 to 30 millimeters, and the horizontal angle α of the silo body is between 60 and 80 degrees.

[0006] The thickness of the ultra-high molecular weight polyethylene inner liner is ten to thirty millimeters. It is made of ultra-high molecular weight polyethylene with a molecular weight greater than five million and contains graphite, giving it self-lubricating properties.

[0007] A mounting frame is fixedly installed on the outer wall of the silo body. An air cannon is installed on the top of the mounting frame. The output end of the air cannon is equipped with an air outlet pipe that extends to the inner side of the silo body.

[0008] The top of the support plate is equipped with an agitation assembly, which includes a motor, an electric push rod one, an electric push rod two, a top plate, a lifting plate, a stirring shaft, and stirring blades. The electric push rod one is fixedly installed at the bottom of the support plate, and its output end is fixedly connected to the top plate. The electric push rod two is fixedly installed at the top of the top plate, and its output end is fixedly connected to the lifting plate. The motor is fixedly installed at the top of the lifting plate, and its output end is fixedly connected to the stirring shaft. The stirring blades are fixedly installed on the outside of the stirring shaft, and their length gradually decreases from top to bottom.

[0009] A dust suppression assembly is provided along the outer wall of the silo body. The dust suppression assembly includes a fan, a return pipe, an extraction pipe, and a shielding groove. The fan is fixedly installed on the top of the support plate, and the shielding groove is fixedly installed on the top of the support plate and located on the outer edge of the silo body. The input end of the fan is connected to the shielding groove, the output end of the fan is connected to the return pipe, and the other end of the return pipe is connected to the inner side of the silo body.

[0010] The beneficial effects of this utility model are: This invention comprises a hopper body, an ultra-high molecular weight polyethylene (UHMWPE) liner, a vibrating device, a gate valve, and an air cannon. The UHMWPE liner enhances the hopper body's wear resistance and shock absorption, while its close fit to the inner wall ensures a smooth surface, reducing friction between materials and improving storage and transport efficiency. The gate valve, located at the bottom of the hopper, allows for precise control of the material flow rate by adjusting its opening, ensuring stable flow during transport. Different discharge rates can be achieved by adjusting the gate valve's opening. During the hopper loading process, the gate valve is closed and an air cannon is used to disperse the adhering materials. When there is slight material adhering to the inner wall of the hopper, the air cannon is operated to disperse the material, and then the gate valve is opened to start the loading operation. The vibrating device can be used in conjunction with the air cannon during the hopper loading process to remove the material adhering to the hopper wall. After the material adhering to the inner wall is cleaned, a strong vibration or blowing airflow is applied to the inner cavity by timed or manual triggering to effectively prevent material agglomeration and blockage, maintain the flowability of materials in the hopper, and then the gate valve and belt conveyor are opened to continue the loading operation.

[0013] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0014] Please see Figure 1-5 As shown, a mineral material anti-sticking feeding silo includes: a silo body 1, an ultra-high molecular weight polyethylene (UHMWPE) inner liner 2, a vibrating device 3, a gate valve 4, and an air cannon 5. The UHMWPE inner liner 2 is attached to the inner wall of the silo body 1. The gate valve 4 is located at the bottom of the silo body 1. Adjusting the opening of the gate valve 4 can regulate the amount of material being conveyed. The vibrating device 3 and the air cannon 5 are respectively located on the outer wall of the silo body 1. A support plate 13 is provided on the top outer wall of the silo body 1. An agitating component is provided on the top of the support plate 13. A dust suppression component is provided along the outer wall of the silo body 1.

[0015] Specifically, the system comprises a hopper body 1, an ultra-high molecular weight polyethylene (UHMWPE) liner 2, a vibrating device 3, a gate valve 4, and an air cannon 5. During operation, the UHMWPE liner 1 enhances wear resistance and shock absorption while adhering to the inner wall, ensuring a smooth surface and reducing friction between materials. This improves the efficiency of material storage and transport. The gate valve 4, located at the bottom of the hopper, allows for precise control of the conveying volume by adjusting its opening, ensuring stable flow during material transport. Adjusting the opening of the gate valve 4 allows for different flow rates. Adjusting the material quantity, while during shed material feeding, closing the gate valve 4 and using the air cannon 5 to disperse the adhering materials. When there is slight material adhering to the inner wall of the silo, operate the air cannon 5 to disperse the material, and then open the gate valve 4 to carry out the feeding operation. The vibrating device 3 can be used in conjunction with the air cannon 5 during shed material feeding to remove the adhering materials from the silo wall. After cleaning the adhering materials on the inner wall, apply strong vibration or blowing airflow to the inner cavity by timed or manual triggering to effectively prevent material agglomeration and blockage, maintain the fluidity of the material in the silo, open the gate valve 4 and the belt conveyor, and continue the feeding operation.

[0016] In this embodiment, a mounting plate 7 is provided at the bottom of the hopper body 1. The thickness of the hopper body 1 is 10 to 30 millimeters, the horizontal included angle α of the hopper body 1 is between 60 and 80 degrees, and the thickness of the ultra-high molecular weight polyethylene inner liner 2 is 10 to 30 millimeters. Its material is ultra-high molecular weight polyethylene with a molecular weight greater than 5 million and contains graphite, which has self-lubricating properties.

[0017] Specifically, the silo body 1 adopts a thinner wall design to ensure that the structure is lightweight and has good rigidity, making it easy to install and transport. At the same time, by setting a horizontal angle, the material's self-flow performance is improved, reducing power consumption. The silo's tilt angle and self-lubricating lining facilitate the natural sliding of materials, reducing power consumption during material conveying.

[0018] A mounting frame 6 is fixedly installed on the outer wall of the silo body 1. An air cannon 5 is set on the top of the mounting frame 6. An air outlet pipe 21 is provided at the output end of the air cannon 5 and extends to the inner side of the silo body 1.

[0019] Specifically, the silo body 1 is equipped with a mounting frame 6 to provide an installation foundation. An external power supply provides electrical energy to the device. An external controller is connected to the device. The controller is electrically connected to the motor 16, electric push rod, air cannon 5, vibrating device 3 and fan 9. The controller uses a PLC board and can be electrically connected to the electrical appliances through programming. The air cannon 5 can be purchased and used directly, and a suitable model can be selected. The vibrating device 3 can be a silo wall vibrator. Other electrical appliances can be purchased or selected as needed. Their working principles, power, etc. are all existing technologies and will not be described in detail here.

[0020] The stirring assembly includes a motor 16, an electric push rod 15, an electric push rod 17, a top plate 14, a lifting plate 18, a stirring shaft 19, and stirring blades 20. The electric push rod 15 is fixedly installed at the bottom of the support plate 13, and its output end is fixedly connected to the top plate 14. The electric push rod 17 is fixedly installed at the top of the top plate 14, and its output end is fixedly connected to the lifting plate 18. The motor 16 is fixedly installed at the top of the lifting plate 18, and its output end is fixedly connected to the stirring shaft 19. The stirring blades 20 are fixedly installed on the outside of the stirring shaft 19, and their length gradually decreases from top to bottom.

[0021] Specifically, the design of the plate and agitation assembly enables the motor 16 to work in concert with the electric push rod 15 and the electric push rod 27 to send the agitator shaft 19 and the agitator blades 20 to the bottom of the hopper, thereby achieving uniform agitation of the material and ensuring the uniformity and flowability of the output. The electric push rod 15 can adjust the height of the top plate 14 so as not to affect the feeding of the hopper body 1. The electric push rod 27 can be equipped with an infrared device, thereby gradually moving the height of the raw material in the hopper so that the agitator blades 20 are adapted to the height of the raw material.

[0022] The dust suppression assembly includes a fan 9, a return pipe 8, an exhaust pipe 10, and a shielding groove 12. The fan 9 is fixedly installed on the top of the support plate 13, and the shielding groove 12 is fixedly installed on the top of the support plate 13 and located on the outer edge of the hopper body 1. The input end of the fan 9 is connected to the shielding groove 12, the output end of the fan 9 is connected to the return pipe 8, and the other end of the return pipe 8 is connected to the inner side of the hopper body 1.

[0023] Specifically, the shielding groove 12 is located on the outer edge of the hopper body 1, collects leaked material and guides it to the return pipe 8. The return pipe 8 sends the material back into the hopper, realizing the recycling of material and avoiding waste. At the same time, it can prevent the dust caused by the air cannon 5 from causing the deterioration of the air environment, thus helping to protect the air environment. When in use, when the extension line extends to the top of the hopper body 1, the shielding groove 12 will initially intercept the material, and the fan 9 will be turned on to perform the air extraction operation, thereby conveying the material back into the hopper body 1 along the extraction pipe 10 and the return pipe 8.

[0024] In use, the silo body 1 is lined with an ultra-high molecular weight polyethylene inner liner 2 to improve wear resistance and shock absorption. This liner adheres to the inner wall, ensuring a smooth surface and reducing friction between materials, thus improving storage and transport efficiency. A slide gate valve 4 is located at the bottom of the silo. Adjusting its opening allows for precise control of the material flow, ensuring stable flow during transport. Adjusting the opening of the slide gate valve 4 allows for different discharge rates. During sizing, the slide gate valve 4 is closed, and an air cannon 5 is used to disperse any adhering materials. If there is slight adhesion to the inner wall of the silo, the air cannon 5 is operated to disperse the material before opening the slide gate valve 4 for loading. A vibrating device 3 can be used in conjunction with the air cannon 5 during sizing to remove adhering materials from the silo wall. After cleaning the adhering materials from the inner wall, a strong vibration or blowing airflow is applied to the inner cavity via timed or manual triggering to effectively prevent material agglomeration and blockage, maintaining material flow within the silo. The slide gate valve 4 and belt conveyor are then opened to continue loading.
