Background
In order to facilitate discharging of the existing single-cone dryer, a discharge valve is generally arranged at the bottom end, and the discharge valve is commonly used and generally adopts a ball valve, such as a double-cone cavity single-cone dryer disclosed by the authorization number CN209524708U and a single-cone dryer with a spiral stirrer disclosed by the authorization number CN 203464623U. However, a rigid ball sealing structure is adopted between the ball valve of the single-cone dryer and the discharge opening at the bottom end of the single-cone dryer, and the top surface of the ball valve is a spherical surface, so that the discharge opening at the bottom end of the single-cone dryer also needs to be processed into a corresponding spherical surface to ensure the sealing effect, the requirement on the processing precision is high, and the processing difficulty is high; in addition, after the rigid sealing structure is used for a plurality of times or for a long time, the discharge opening and the surface of the ball valve can generate large abrasion, the sealing effect is influenced, if the rigid sealing structure needs to be replaced, the whole ball valve needs to be replaced, and the cost is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, easy dismounting, be convenient for change, life longer single awl desiccator that has gasbag sealing mechanism.
The utility model discloses a realize through following technical scheme: the utility model provides a single cone desiccator with gasbag sealing mechanism, includes single cone desiccator body and sets up the row's material ball valve in single cone desiccator body bottom, it is provided with gasbag sealing mechanism to arrange between material ball valve and the single cone desiccator body, gasbag sealing mechanism includes mounting flange and sealed gasbag, mounting flange fixes on the discharge gate of single cone desiccator body bottom, and mounting flange has seted up annular groove for arranging on a side of material ball valve, sealed gasbag cover is established in annular groove, and sealed gasbag part exposes the annular groove outer and with arrange material ball valve top face offset and lean on.
In order to facilitate the inflation of the sealed air bag, an inflation inlet is formed in one end of the mounting flange and is communicated with the inside of the sealed air bag.
Because the sealing air bag can generate larger deformation after being inflated and can possibly fall off the annular groove to influence the sealing effect, the annular groove is designed to be in a step shape, and the width of the inner end of the annular groove is larger than that of the outer end of the annular groove; the sealing air bag is designed into a U shape, and one end of the sealing air bag, which is far away from the discharge ball valve, is provided with a flange, and the flange is embedded into the inner end of the annular groove.
In order to avoid the large deformation of the sealing air bag in the annular groove, an annular ferrule is arranged in the annular groove, the annular ferrule is embedded into a U-shaped notch of the sealing air bag, and the annular ferrule can limit and guide the sealing air bag to achieve a better sealing effect.
The utility model has the advantages that: this single cone desiccator with gasbag sealing mechanism cooperatees with the ball valve through the gasbag sealing mechanism of special design, and for rigid seal, flexible seal effect is better, and life is longer, uses when maintaining after the longer time, only needs to change the gasbag, and the maintenance cost is lower.
