Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coal bunker anti-blocking, in particular to a partition bunker with a novel gate valve. BACKGROUND

[0002] In order to adapt to the demand of flexible coal blending and rapid peak shaving, a fire power plant adds a partition plate in the middle of a coal bunker, so that the bunker becomes a partitioned bunker, high-quality coal is fed on one side and low-quality coal is fed on the other side, low-quality coal is used for power generation in normal times, and coal diversification is realized; when the power grid dispatching needs to reduce power generation, in order to ensure that the fire is not extinguished and the combustion is stable, high-quality coal needs to be burned. When high-quality coal is burned, the valve on one side is opened, and when low-quality coal is burned, the valve on the other side is opened. The partitioned bunker not only can add different types of coal on both sides of the partition plate to realize coal diversification, but also can ensure normal production work during the production peak period if the clogging occurs on one side of the bunker and the other side of the bunker can work normally. The above functions are realized by relying on a novel valve. For example, if the clogging does not occur on one side of the bunker, the valve plate on the side can be opened to realize smooth discharge, or if a certain type of coal is needed, the valve plate on one side can be opened without opening all the valve plates, which reduces the waste of resources.

[0003] However, the existing split gate valve can only be opened or closed at the same time, and cannot realize single-side opening or single-side closing of the partitioned bunker. In addition, the existing gate valve for hydraulic cylinder is arranged outside the valve body, which occupies a large space and cannot adapt to smaller space use. After long-term use of the partitioned bunker with the added partition plate, the strength of the partition plate is limited, the service life is generally short, and the partition plate is easily damaged after long-term use, which affects the normal production when replaced.
