Air Locking System and Air Locking Method of Two-Stage Air Shutter

Abstract

The invention relates to a two-stage air-lock air locking system and an air locking method thereof. The air locking system comprises a two-stage air lock body connected with a material storage device, an inert gas generator, a driving system and a pressure control system, the two-stage air lock body is connected with the driving system, the inert gas generator is connected with the pressure control system and then simultaneously connected to the material storage device and the two-stage air lock body, two-three stainless-steel spring steel sheets are mounted on blades of air locks, are in flaky arrangement and are overlapped on the inner wall of housings of the air locks in an arc manner. The system is better in sealing property and wide in applicable temperature range; particularly, leakage of on-site toxic and harmful gases can be reduced greatly, and physical and mental health of workers is protected.

Description

technical field [0001] The invention relates to an air lock system for bulk material conveying or blanking of storage equipment, in particular to a two-stage air lock with stainless steel elastic sealing sheets at the blanking place of bulk material conveying or storage equipment Air lock system. Background technique [0002] The air lock is an important equipment widely used in the conveying, screening, loading and unloading systems of bulk materials such as mines, chemicals and coal. When transporting materials, in order to prevent the blades of the air lock from being stuck, anti-seize parts are generally added to the body of the air lock. In the gap between the machine casing and the blades, the system cannot discharge materials normally. At present, most air locks use high-temperature and wear-resistant rubber as the sealing material, but the maximum operating temperature of this type of air lock is only 280°C, and cannot transport materials with higher temperatures. ...

AI Technical Summary

Problems solved by technology

When transporting materials, in order to prevent the blades of the air lock from being stuck, anti-seize parts are generally added to the body of the air lock. In the gap between the casing and blades of the machine, the system cannot discharge materials normally

At present, most air locks use high-temperature and wear-resistant rubber as the sealing material, but the maximum operating temperature of this type of air lock is only 280°C, and cannot transport materials with higher temperatures

In addition, there is a gap between the air locker casing and the blades, which cannot guarantee the complete airtightness of the system, and may easily cause gas leakage

This is allowed in the general production process, but in some chemical processes that can generate toxic and flammable gases, if the system cannot be sealed, the toxic or flammable gases leaking from the discharge port will not only cause environmental pollution, but also be more serious. It may also cause accidents such as personnel poisoning or explosion
