Problems solved by technology

However, in the actual application process, there are certain problems in the feeding device of the biomass boiler, and there is a large room for improvement and optimization.
[0003] Biomass fuel often contains a large amount of combustible dust, and the proportion of combustible volatile matter in biomass fuel is very large, which leads to the increase of deflagration or sudden positive pressure in the furnace during its combustion process, and biomass fuel has a burning speed Due to the fast characteristics, the open flame or high-temperature flue gas produced by fuel combustion will ignite the combustible dust and fuel in the fuel hopper through the feeding channel, causing serious safety accidents. The air locker is aimed at different fuels, and the fuel cannot be opened and adjusted

Embodiment 1

[0014] Embodiment 1: as figure 2 As shown, a biomass briquette fuel boiler feeding adjustable locking device includes an inclined flap 9 and a gravity hammer 10. The flap 9 is connected to the lower end of the drop tube 3 and connected to the drop tube 3 through a hinge 11. A section of the cantilever rod 12 extends from the side of the lower end and the connecting end of the flap. The end of the cantilever rod 12 is fixedly connected to the gravity hammer 10 through the suspension rod. The force adjustment device is installed on the cantilever rod. The structure is simple, self-locking is convenient and easy, and the cost is low. The flap-type air lock with this structure can effectively prevent clogging, feed more evenly, and prevent high-temperature smoke and open flames from entering the feeder and hopper, preventing fuel in the fuel hopper from being diverted.

[0015] Preferably, there are two gravity hammers 10, which are symmetrically arranged at the front and rear en...

Embodiment 2

[0017] Embodiment 2: as Figure 1-2 As shown in the figure, an adjustable locking device for biomass briquette fuel boiler includes a front feed bin 1, a feeder 2, a feeding pipe 3 and an adjustable locking device 4. The adjustable locking device adopts a flap lock The gas device, the front feed bin 1 is in the shape of a trumpet with a large top and a small bottom. The feeder 2 is installed at the lower end of the furnace feed bin 1, and the lower end of the furnace feed bin 1 is connected to the boiler’s drop pipe 3, which is The lower end is connected with an adjustable locking device 4.

[0018] Preferably, the above-mentioned material shifter 2 is connected to the primary shift output shaft of the transmission 7 through a primary belt transmission mechanism, and the secondary transmission output shaft of the transmission 7 is connected to the grate main shaft 6 through a secondary belt transmission mechanism, and the input of the transmission 7 The shaft is connected to ...

Abstract

The invention discloses a feeding adjustable locking device for a biomass forming fuel boiler. The feeding adjustable locking device comprises an oblique overturning plate and a gravity hammer. The overturning plate is connected to the lower end of a blanking pipe in a covering mode and connected to the side portion of the lower end of the blanking pipe through a hinge, and a section of cantileverrod extends out of the connecting end of the overturning plate. The end of the cantilever rod is connected with the gravity hammer. A force adjusting device is installed on the cantilever rod. According to the feeding adjustable locking device for the biomass forming fuel boiler, the force adjusting device is arranged, the torque of the connecting end of the gravity hammer can be adjusted, thus,weight adjusting can be achieved when different biomass fuels are fed, the application range is greatly enlarged, and the equipment transformation cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of boiler feeding devices, and in particular relates to an adjustable locking device for biomass briquette fuel boiler feeding. Background technique [0002] A boiler is an energy conversion device that outputs the chemical energy of fuel combustion into steam, high-temperature water or organic heat carrier with certain heat energy. Compared with other types of boiler equipment, biomass boilers have a wide range of fuel types and excellent pollutant emission indicators. However, in the actual application process, there are certain problems in the feeding device of the biomass boiler, and there is a large room for improvement and optimization. [0003] Biomass fuel often contains a large amount of combustible dust, and the proportion of combustible volatile matter in biomass fuel is very large, which leads to the increase of deflagration or sudden positive pressure in the furnace during its combustion proces...
