Example Embodiment

[0007] Specific embodiment 1: This embodiment is described with reference to FIG. 1. This embodiment is composed of a biomass lower hopper 1, a biomass upper hopper 2, a hinged dragon 3, a motor 4, and a boiler 16. The biomass upper hopper 2 is set in the biomass The upper left end surface of the upper end of the material lower hopper 1 and the lower biomass hopper 1 communicate with the upper biomass hopper 2, and the hinged dragon 3 extends from the left end surface of the lower end of the upper biomass hopper 2 into the lower biomass hopper 1 In the upper biomass hopper 2, the left end of the hinged dragon 3 is connected with the motor 4, and the lower biomass hopper 1 is arranged on the left end surface of the boiler 16.

Example Embodiment

[0008] Specific embodiment 2: This embodiment will be described with reference to Figs. 1 to 3. The difference between this embodiment and the first embodiment is that the present invention also adds a material shifter 5 and a guide rail 6, and the material shifter 5 is driven by a motor. 7. The reducer 8, the crank 9, the connecting rod 10, the rake 11, the roller 12 and the support 13, the pulley 7-1 of the motor 7 is connected to the reducer 8, and the output shaft of the reducer 8 is 8- 1 is hinged with the lower end of the crank 9, the upper end of the crank 9 is hinged with the connecting rod 10, the right end of the connecting rod 10 passes through the side wall of the biomass lower hopper 1 and is hinged with the target vehicle 11, and the roller 12 is installed under the target vehicle 11. The two ends of the guide rail 6 are fixed on the front and rear ends of the lower biomass hopper 1 respectively, and a support 13 is provided under the reducer 8. With this setting, th...

Example Embodiment

[0009] Specific embodiment 3: This embodiment will be described with reference to Fig. 1. The difference between this embodiment and the first embodiment is that the present invention also adds a biomass baffle 14 which is arranged in the biomass lower hopper 1 on the right inner wall. With this setting, the thickness of the biomass fuel can be adjusted. The other composition and connection relationship are the same as in the first embodiment.

Abstract

A chain-type boiler backfire protection feed apparatus for biomass combustion relates to a chain-type boiler backfire protection feed apparatus. The invention resolves the problem in prior chain-type boiler in direct biomass combustion that the biomass might be burned in buckets due to backfire caused by high biomass combustion speed. The invention comprises a biomass lower bucket (1), a biomass upper bucket (2), an articulate vane (3) and a motor (4); wherein, the biomass upper bucket (2) is arranged on the left end face of the upper-end of the biomass lower bucket (1); moreover, the biomass lower bucket (1) communicates with the biomass upper bucket (2); the articulate vane (3) reaches the biomass lower bucket (1) and the biomass upper bucket (2) through the left end face on the lower-end of the biomass upper bucket (2); the left end of the articulate vane (3) is linked to the motor (4). The invention simultaneously utilizes the multi-stage with feed the biomass upper bucket, the biomass lower bucket and the articulate vane, so as to avoid backfire due to high combustion speed for biomass fuels, so that the biomass is burned in the buckets; therefore, the invention can guarantee the safety of boilers.

Description

technical field [0001] The invention relates to an anti-tempering feeding device for a chain boiler, which belongs to the technical field of industrial boilers. Background technique [0002] With the rising prices of fossil fuels such as oil and natural gas, the development of renewable energy has become a global hot issue and an inevitable choice for the development of sustainable energy. Compared with fossil energy, biomass energy has great advantages. Biomass energy CO 2 The net emission is zero, which can effectively alleviate the greenhouse effect. Its sulfur and nitrogen contents are very low, and its ash content is also very small. Therefore, the development and utilization of biomass energy is an effective way to relieve energy and environmental pressure and establish a sustainable energy system. measure. In order to save energy and reduce emissions, small thermal power units using chain grates with high energy consumption, low efficiency and high pollution will be...
