Description

Technical Field

[0001] This utility model belongs to the field of hopper technology, specifically relating to a powder vacuum hopper. Background Technology

[0002] In the process of conveying and processing powder materials, several technical challenges are often encountered, particularly regarding material flowability, conveying efficiency, and dust pollution control. Traditional powder material conveying systems typically employ mechanical or pneumatic conveying methods, but these methods often have limitations in practical applications.

[0003] When powdered materials flow within conveying pipelines, the properties of the powder itself and the structure of the conveying equipment often generate significant friction and air resistance, leading to impeded material flow, reduced conveying efficiency, and even potential blockages. This not only increases the operational burden on the equipment but also increases energy consumption and reduces production efficiency.

[0004] Powder materials are prone to dust leakage during transportation, especially at openings and connections. Airborne dust not only poses a threat to the health of operators, but long-term accumulation can also corrode or clog equipment, affecting its normal operation. Furthermore, dust pollution can lead to environmental pollution and violate environmental regulations.

[0005] Traditional powder conveying equipment is typically complex in design and often has a fixed structure, making maintenance and cleaning inconvenient. When equipment malfunctions or requires cleaning, it often necessitates disassembling numerous parts, which is time-consuming and labor-intensive. Furthermore, due to the inherent properties of powder materials, material tends to accumulate on the equipment during use, further complicating cleaning.

[0006] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

Detailed Implementation

[0020] like Figures 1 to 4As shown, a powder vacuum hopper includes a mounting frame 10. The top of the mounting frame 10 has a mounting panel 11. A mounting slot 111 is formed in the center of the surface of the mounting panel 11. A hopper component 20 is connected to the mounting slot 111. The top of the hopper component 20 has a hopper connecting portion 21. An air inlet component 30 is connected to the top of the hopper connecting portion 21. An air inlet opening 31 is connected to the side of the air inlet component 30. A feed opening 22 is connected to the side wall of the hopper component 20. The bottom of the hopper component 20 is connected to... During use, the air inlet 31 is connected to a pneumatic compressor, which applies pressure to the hopper component 20. This pressure forces the powder material in the hopper component 20 through the air inlet 22 into the hopper component 20, and then outputs it to downstream equipment through the discharge outlet 23. Throughout the process, the air inlet 31, the air inlet 22, and the discharge outlet 23 ensure the flow and distribution of material in the hopper. By applying pressure through the pneumatic compressor, resistance can be reduced and conveying efficiency improved during the conveying of powder material.

The dustproof net 40 is correspondingly arranged with the air inlet 211. When the air inlet 31 is in the air intake, the airflow will first pass through the dustproof net 40 to prevent large particles in the air from entering the hopper component 20. This helps to keep the system clean and reduce dust pollution, which is especially important when processing high-precision or high-purity materials.

[0022] In practical implementation, the edge of the dustproof net 40 is provided with a net connecting part 41.

When it is necessary to disassemble, the connecting fastener 25 can be pried outward to release the connecting buckle part 251 from the connecting buckle groove 33, thereby loosening the air intake component 30. This design makes it easy to remove the air intake component 30 from the hopper component 20 for cleaning or replacement, improving the maintenance efficiency of the equipment and making it convenient to use.

[0025] In practical implementation, the two side walls of the hopper component 20 are symmetrically provided with fixed mounting seats 26, and the two sides of the mounting slot 111 are symmetrically provided with mounting through holes 112. The fixed mounting seats 26 and the mounting through holes 112 are correspondingly arranged, and are connected and fixed by fasteners passing through the fixed mounting seats 26 and the mounting through holes 112, so that the hopper component 20 is fixedly connected in the mounting frame 10. The structure is simple and the installation is convenient.

[0026] In summary, the mounting frame 10 has a mounting panel 11 on its top, and a mounting slot 111 is formed in the center of the surface of the mounting panel 11. A hopper component 20 is connected to the mounting slot 111. The top of the hopper component 20 has a hopper connecting part 21, and the top of the hopper connecting part 21 is connected to an air inlet component 30. An air inlet opening 31 is connected to the side of the air inlet component 30.
