Pneumatic conveying equipment

Abstract

The invention discloses pneumatic conveying equipment. The pneumatic conveying equipment comprises a feeding bin, a hopper, a material amount adjusting device, a rubber sealing ring, a mixing tank, afan and a material storage device, wherein the feeding bin is connected with the hopper through the rubber sealing ring, the lower end of the hopper is funnel-shaped, and a discharging port is formedin the bottom of the hopper; the material amount adjusting device comprises a driving lifting device, an adjusting rod and a cross beam, the cross beam is arranged in the hopper, the driving lifting device is fixed on the cross beam, the adjusting rod is connected with the driving lifting device and performs lifting motion under the driving of the driving lifting device, and the bottom of the adjusting rod is in an inverted cone shape; the bottom of the adjusting rod is suspended in the center of the discharging port, the discharging port is connected with the mixing tank, the mixing tank is connected with the material storage device, and the top of the material storage device is connected with the fan. By the adoption of the pneumatic conveying equipment, the function of adjusting the discharging amount of the discharging port in unit time and ensuring the uniform discharging of the hopper can be realized, thereby ensuring uniform conveying of material.

Description

technical field [0001] The invention relates to the technical field of material conveying, in particular to a pneumatic conveying device. Background technique [0002] Pneumatic conveying, also known as airflow conveying, uses the energy of airflow to transport granular materials along the direction of airflow in a closed pipeline, and is a specific application of fluidization technology. The structure of the pneumatic conveying device is simple, the operation is convenient, and it can be used for conveying in horizontal, vertical or inclined directions. In the production process, the control and transportation of the material volume are completed separately by the mechanical control device and the pneumatic conveying device. This kind of pneumatic conveying that adopts the joint working method can control the material-air ratio of the conveying to achieve the maximum conveying capacity of the device, but now Some feeders (such as star feeders), the star feeder relies on th...

In the production process, the control and transportation of the material volume are completed separately by the mechanical control device and the pneumatic conveying device. This kind of pneumatic conveying that adopts the joint working method can control the material-air ratio of the conveying to achieve the maximum conveying capacity of the device, but now Some feeders (such as star feeders), the star feeder relies on the rotation of the impeller to unload, and there must be enough space between the impeller and the casing to allow the impeller to rotate in the casing, but When th
