Example Embodiment

[0014] Example 1: Such as figure 2 As shown, a biomass fuel boiler feed adjustable locking device includes an inclined flap 9 and a gravity hammer 10. The flap 9 is connected to the lower end of the blanking pipe 3, and is connected to the blanking pipe 3 through a hinge 11 A section of the cantilever rod 12 extends from the lower end side and extends from the flap connection end. 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 of this structure can effectively prevent clogging, and while feeding more uniformly, it can prevent high-temperature flue gas and open flame from entering the shifter and hopper back, and prevent fuel in the fuel hopper.

[0015] Preferably, the above-mentioned gravity hammers 10 are provided with two, which are symmetrically arra...

Example Embodiment

[0017] Example 2: Such as Figure 1-2 As shown, an adjustable locking device for feedstock of a biomass fuel boiler includes a silo 1 in front of the furnace, a shifter 2, a blanking tube 3, and an adjustable locking device 4, the adjustable locking device adopts a flap type lock The gas generator, the furnace front silo 10 is trumpet-shaped up and down, and the feeder 2 is installed at the lower end of the furnace front silo 1. The lower end of the furnace front silo 1 is connected to the blanking pipe 3 and the blanking pipe 3 of the boiler. The lower end is connected with an adjustable locking device 4.

[0018] Preferably, the shifter 2 described above is connected to the primary transmission 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 co...

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...
