Problems solved by technology

The common feature is one-stage. Due to the characteristics of high volatile content and rapid combustion of biomass fuel, it is especially easy to backfire to the hopper or feeding device in front of the furnace, which often causes the problem that the equipment cannot be used when it is shut down; Adjusting the speed and stroke can not cope well with various complex combustion conditions; the feeding device is an ordinary hopper without anti-tempering function

Abstract

The invention discloses a three-stage type hydraulic driving biomass reciprocating fire grate, which comprises a fixing column, three hydraulic driving devices, and a frame, a first segment fire grate, a second segment fire grate and a third segment fire grate are successively arranged in the frame from top to bottom, each segment of the fire grate includes a movable frame, a connecting shaft, fire grate pieces, movable beams, fixed beams, steel plates, idler wheels and supporting frames; each movable framecomprises a bottom beam and a movable inclined beam which are connected,a plurality of reinforcing beams are arranged between the bottom beams and the movable inclined beams, the movable inclined beams are installed on the frame, a plurality of steel plates are arranged on the lower faces of the bottom beams, the idler wheels are arranged between the steel plates and the supporting frames, the bottom beam in each segment of the fire grate is connected to one end of the correspondinghydraulic driving device, and the other ends of the hydraulic driving devices are connected to the fixing column. According to design, combustion of biomass in a hopper is effectively prevented, hydraulic pushing is stable, operation is stable, the use effect is good, and the operation speed is adjusted according to the combustion condition.

Description

technical field [0001] The invention relates to a biomass reciprocating fire grate, in particular to a three-stage hydraulically driven biomass reciprocating fire grate. Background technique [0002] Biomass fuel, as a renewable and clean energy, is an energy vigorously promoted by the state, replacing disposable fossil energy such as coal and petroleum. [0003] At present, the utilization equipment of biomass energy in the market is mainly reciprocating grate, chain grate and so on. The common feature is one-stage. Due to the characteristics of high volatile content and rapid combustion of biomass fuel, it is especially easy to backfire to the hopper or feeding device in front of the furnace, which often causes the problem that the equipment cannot be used when it is shut down; Adjusting the speed and stroke cannot well deal with various complex combustion conditions; the feeding device is an ordinary hopper without the anti-tempering function.
