Counter weight type bridge breaking device

Abstract

The invention relates to a heavy hammer type bridge breaking device which comprises a vertically-arranged frame body, the frame body is arranged on the inner side wall of the rear wall of a feeding hopper, a hammer head integrated with the frame body is arranged at the lower end of the frame body, the frame body is connected with the telescopic end of a breaking frame hydraulic cylinder, the breaking frame hydraulic cylinder is vertically arranged, and the telescopic end of the breaking frame hydraulic cylinder faces downwards. The upper end of the frame breaking hydraulic cylinder is fixed to the upper end face of the rear wall, the telescopic end of the frame breaking hydraulic cylinder is fixedly connected with the lower end of the interior of the frame body after the frame breaking hydraulic cylinder stretches into the frame body, limiting plates are fixed to the portions, on the left side and the right side of the frame body, of the rear wall and are parallel to the rear wall, and the corresponding end of the frame body is located between the limiting plates and the rear wall. A second guide groove of the frame body is formed between the rear wall and the limiting plate. A simple heavy hammer structure is adopted, and garbage bridging is forcibly relieved through up-and-down movement of the heavy hammer.

Description

technical field [0001] The invention belongs to the technical field of domestic waste incineration, and relates to a heavy hammer type bridge breaking device. Background technique [0002] The feeding system of the waste incineration process is mainly used to receive and store waste, and through a reciprocating mechanism, the stored waste is continuously and safely transported to the grate for incineration. The detailed structure includes feeding hopper, chute and feeder (feeding trolley, feeding platform). [0003] The feeding hopper adopts a trapezoidal funnel structure to accept the garbage caught by the garbage crane grab. The specific inclination angle of the front wall of the hopper ensures that the garbage can continuously slide into the chute of the feeding channel under the action of its own weight. The bottom of the feed hopper is connected with the chute, and the chute is a straight pipe structure with a rectangular cross-section. The size of the rectangular cros...

Problems solved by technology

On the other hand, in addition to the fermentation process, waste incineration does not pre-treat the waste, the size of the waste is too large, and the waste is densely piled up, which may cause bridging at the connection position between the bottom of the waste feed hopper and the chute.

[0005] After the bridge is erected, the garbage in the feeding hopper cannot slide down by its own gravity. As the feeding trolley continues to push in, the garbage below the bridge-building position will be pushed empty, causing the temperature of the cavity above the feeding platform to exceed High, the garbage around the cavity will catch fire. In severe cases, the burning surface of the garbage caused by the cavity will expand, and the garbage on the entire feeding platform will be sintered, causing all the feeding trolleys to be unable to push out the sintered garbage, and the entire furnace cannot continue to move forward. material
