There are many types of shut-off fans, especially chain-driven shut-off fans. However, the existing chain-type shut-off fans cannot automatically lubricate the chain when the chain is rotating, and cannot quickly replace the chain, or perform maintenance on the chain. It is necessary to disassemble the entire chain box, which not only wastes time and is inefficient, but also easily causes the chain box to loosen, resulting in a reduction in the service life of the equipment

Abstract
The invention discloses a chain transmission type rotary valve convenient to maintain. The chain transmission type rotary valve convenient to maintain comprises a rotary valve body, a box body, a bottom plate, a discharging hopper, a connecting flange, a flange connecting bolt hole, a material shifting impeller, an impeller bearing, a sealing gasket, a motor, a junction box, a gear box, a rotatingshaft, a chain box, a chain box cover, a lubricating oil box, a transparent acrylic plate, a buckle, a hinge, an oil dipping sliver, an oil inlet, a feeding hopper and a chain, wherein the bottom plate is arranged at the bottom end of the rotary valve body, the discharging hopper is arranged at the top end of the bottom plate, the box body is arranged at the top end of the discharging hopper, andthe material shifting impeller is arranged in the box body. The rotary valve can quickly open the chain box, can replace a chain without disassembling the chain box, can quickly brush oil on the chain, prevent the chain from rusting and affecting the service life, can see the service condition of the chain, improve the maintenance efficiency, ensure the normal use of the rotary valve and prolongthe service life of the rotary valve.
Description
Technical field: [0001] The invention relates to the technical field of fan shutdown, in particular to a chain-driven fan shutdown that is convenient for maintenance. Background technique: [0002] The closed fan is used in the pneumatic conveying pipeline, also known as the closed air device. The material falls into the pneumatic conveying pipeline below through the casing of the closed fan, and the material is transported by the centrifugal fan or other pneumatic forces. There are many types of shut-off fans, especially chain-driven shut-off fans. However, the existing chain-type shut-off fans cannot automatically lubricate the chain when the chain is rotating, and cannot quickly replace the chain, or perform maintenance on the chain. It is necessary to disassemble the entire chain case, which not only wastes time and is inefficient, but also easily causes the chain case to loosen, resulting in reduced service life of the equipment. [0003] Therefore, how to design a cha...
