Straw discharging equipment capable of performing intermittent discharging and speed-change pushing, for electricity generation with agricultural garbage

Abstract

The invention relates to the technical field of electricity generation with agricultural garbage, and discloses straw discharging equipment capable of performing intermittent discharging and speed-change pushing, for electricity generation with agricultural garbage. The straw discharging equipment comprises a frame plate, wherein cone disks are movably connected to the outer side of the frame plate. A gear rotates to enable baffles to be away from each other and then close to each other, so that intermittent falling down of materials can be realized, and the situation that too many materials are crushed in one time so that the crushing effect of the materials is influenced can be avoided; the cone disks drive arc disks to rotate, and then a material transmitting rod on the outer side of athird rotating disk rotates, so that the materials are pushed; besides, the gear enables an arc top region of each arc disk and a region away from the arc top region to be attached to the corresponding cone disk alternately, and the speed of the arc disks changes; when a discharge opening is opened, the material transmitting rod rotates at the largest speed, and the materials are quickly discharged; and when the discharge opening is in closed state, the material transmitting rod rotates at the smallest speed, the materials are pushed to a position above the discharge opening at a low speed, preparation is performed for subsequent discharging, and the situation that the materials are stacked and compressed due to large rotational speed and discharging is disadvantageous can be avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural waste power generation, in particular to a straw discharge device for agricultural waste power generation with intermittent discharge and variable speed pushing. Background technique [0002] Agricultural waste power generation refers to the use of agricultural waste, such as crop straw, weeds, etc., under anaerobic conditions, through the catabolism of various microorganisms with a large number and different functions, and anaerobic fermentation to generate biogas to drive The operation of biogas generator sets for power generation not only solves the environmental problems in biogas projects, consumes a lot of waste, protects the environment, reduces greenhouse gas emissions, but also turns waste into wealth, generating a lot of heat and electricity, which is in line with energy The environmental protection concept of recycling also brings huge economic benefits.

Problems solved by technology

[0003] Before power generation, it is necessary to mix the crushed straw with the biogas slurry evenly. The current straw discharge equipment often discharges the straw directly, which often leads to uneven mixing of the biogas slurry and the biogas slurry due to excessive discharge, reducing the biogas production of straw fermentation. The quantity affects the power generation effect, so that the straw cannot be effectively used. At present, although some equipment can be blanked in batches, because the speed of the pushing mechanism of the equipment is consistent, when the blanking is not performed, the pushing mechanism will continue to push the straw to the outlet. Above the feed port, the straw is accumulated and compacted at the discharge port, causing blockage and reducing work efficiency
