Anti-falling structure for hopper

Abstract

The present invention provides a high safety factor anti-falling structure for a hopper, wherein the structure is used for a top packing type gasifier, and is provided for eliminating hidden danger caused by hopper falling due to rope breakage. The hopper anti-falling structure comprises a hopper and a pulling support. The hopper is connected with a pulling rope, such that the hopper can be lifted or lowered under the rope pulling effect. The pulling support is provided with vertical guide rails, wherein the guide rails are intervally provided with a plurality of snapping concave portions or snapping through holes. Pin passing through holes are arranged on side walls of the hopper, wherein the position of the pin passing through hole is corresponding to the guide rail. Locking pins are arranged inside the hopper, wherein the locking pins can snap into the snapping concave portions or the snapping through holes. When the rope is pulled to perform a pulling action, the locking pin can be driven to exit from the driving portion of the snapping concave portion or the snapping through-hole, and when the rope is broken, the locking pin can be driven to pass through the pin passing through hole to extend to the reposition portion of the snapping concave portion or the snapping through-hole. According to the hopper anti-falling structure of the present invention, the match of the locking pins and the guide rails is adopted, such that the hopper can be fixed on the guide rails when the pulling rope is broken so as to avoid free falling of the hopper.

Description

technical field [0001] The invention belongs to the technical field of biomass energy utilization, and in particular relates to a hopper anti-falling structure used in a biomass gasification furnace. Background technique [0002] With the gradual implementation of low-carbon emission reduction policies, coal-fired, diesel or wood-fired boilers in various places will be gradually phased out or transformed, thus bringing overall opportunities to the biomass gasification instead of oil combustion industry. Biomass gasifier can realize clean combustion and high-efficiency utilization of biomass fuel. It is clean, environmentally friendly and cheap, and it is a new trend of energy utilization. Biomass gasifiers that use pellets as raw materials can be continuously filled with augers or trays, but for large volumes of irregularly shaped block or strip-shaped scraps from furniture manufacturers, the aforementioned methods cannot be used. Way. The utility model patent with the pa...

Biomass gasifiers that use pellets as raw materials can be continuously filled with augers or trays, but for large volumes of irregularly shaped block or strip-shaped scraps from furniture manufacturers, the aforementioned methods cannot be used. Way

The utility model patent with the patent number of 200620058696.4 discloses a way of lifting and lowering the hopper with a rope pulley mechanism, and using the hopper to fill from the top of the gasifier. However, this filling method has potential safety hazards: once the rope breaks, hundreds of kilograms The hopper will be in a free fall from a height of 7 to 8 meters and a dangerous situation will occur
