Problems solved by technology

[0002] Hoppers are widely used in the field of material transportation, and there are many types and structures, but there are still many places to be improved: 1. The sealing effect of the existing hoppers is poor, and the powdery materials are easy to leak during the transportation process
2. The amount of material in the conveying process cannot be accurately controlled, and cannot meet the needs of complex processes and refined production
3. The operation is cumbersome, and it is inconvenient to overhaul and maintain

Abstract

The invention relates to a seal charging valve and relates to the field of hoppers. The seal charging valve comprises a hopper; the lower end of the hopper is provided with a discharge hole; the upper end of the hopper is provided with a charging plane sluice gate; the charging plane sluice gate is provided with a bell sealing structure; the discharge hole of the hopper is provided with an automatically controlled seal sluice gate. According to the seal charging valve, a charging hole is provided with the charging plane sluice gate and the discharge hole is provided with the bell; during charging, the charging plane sluice gate is opened, the bell is closed, and materials enter the hopper from a raw material cabin; during discharging, the charging plane sluice gate is closed, the bell is opened, the seal charging valve operates in a recycle mode as above, and the charging plane sluice gate and the bell alternately operate in a combination mode; meanwhile the charging plane sluice gate and the bell are provided with seal structures, dust is prevented from escaping, air flows are effectively prevented from flowing reversibly, and accordingly stabilization of air pressure inside a system and normal discharging of materials are guaranteed.

Description

technical field [0001] The invention relates to the field of hoppers, in particular to a sealed charging valve. Background technique [0002] Hoppers are widely used in the field of material transportation, and there are various types and structures, but there are still many areas to be improved: 1. The sealing effect of the existing hoppers is poor, and the powdery materials are easy to leak during the transportation process. 2. The amount of material in the conveying process cannot be accurately controlled, and cannot meet the needs of complex processes and refined production. 3. The operation is cumbersome, and it is inconvenient to overhaul and maintain. Contents of the invention [0003] The object of the present invention is to provide a sealed charging valve with good sealing effect and accurate control of material flow. [0004] The technical solution to achieve the above purpose is: sealing the charging valve, including a hopper, the lower end of the hopper is p...
