Description

Direct pushing type bridging breaking device suitable for garbage incinerator

Technical Field

The invention relates to the field of incineration, in particular to a bridging breaking device applied to a feeding system of a garbage incinerator.

Background

The garbage incineration method has the advantages of remarkable reduction effect, land saving, capability of eliminating various pathogens, innocuous treatment of toxic and harmful garbage and the like, and becomes one of the main stream methods for urban garbage treatment.

The incinerator feeding system of one of the subsystems of the garbage incinerator equipment is characterized in that a main garbage feeding hopper is designed into a hopper body with a large upper part and a small lower part, and the main garbage feeding hopper is provided with a loose feeding and compacting process, so that when materials enter the throat part of the hopper body, the bridging phenomenon of garbage is easily caused. Bridging can cause blockage of the feed hopper, affecting delivery of the feed hopper of the incinerator and subsequent combustion of the incinerator.

The existing common schemes for treating garbage bridging are a horizontal baffle method and a swinging baffle method. The horizontal baffle plate method drives the baffle plate to translate in the horizontal direction through a hydraulic cylinder arranged at an inlet at the upper part of the hopper. According to the scheme, the problem that the bridge of the garbage in the feed hopper is broken and meanwhile part hidden danger is reserved is solved, the bridge breaking baffle is located in the feed hopper to occupy the space of the garbage falling channel when the bridge breaking baffle is not started, and the probability of bridging is increased; the bridge breaking device can cause damage to the service life of equipment due to the fact that the driving rod is directly contacted with garbage in the driving process when in motion; the garbage can collide with the bridging cracking device in the feeding process, and equipment failure can be caused by scratching.

The swing type bridge breaking device can be stored on the back of the feed hopper, so that the condition of direct contact with the garbage to be fed is reduced, the falling channel of the garbage is not occupied, but a driving part of the swing type bridge breaking device can enter the incinerator, a soft connecting device is needed, an independent bridge breaking device panel is arranged, and the operation and maintenance difficulty and cost are increased.

Detailed description of the preferred embodiments

As shown in fig. 1, the position of the bridge breaking structure is schematically shown. The 02 wedge is now in the initial position. The 01 gear rack driving box is fixedly connected to the upper part of a horizontal plate of the 05 feed hopper body through bolts and nuts; the gear shaft 101 is fixed on the shell 104 in a bearing mode, the dovetail guide rail 103 is fixed on the shell 104 in a welding mode, and the rack 102 is engaged with the gear shaft 101 and clamped in the dovetail guide rail 103.

As shown in fig. 2, the initial position view of the bridge breaking structure is shown, and the 02 wedge is at the initial position. The 03 reduction gearbox and the 04 motor are fixed on a 202 fixed platform in a bolt and nut connection mode, the 04 motor is connected with the 03 reduction gearbox through a 203 coupling, and a 101 output shaft as an output end of the 03 reduction gearbox passes through a 201 bearing to be sealed and enters a 104 shell. The 02 wedge block is positioned at the right-angle cavity of the 05 feed hopper shell, so that the descending channel of the material is not influenced, and the contact opportunity with the material is reduced.

As shown in fig. 3, the working position of the bridge breaking structure is shown, and the 02 wedge is in the working position. When the materials fall, a bridging phenomenon is generated, the 04 motor is started, the input end of the 03 reduction gearbox is connected through the 203 coupling, the 101 gear shaft slowly rotates at a constant speed after the reduction effect, the 02 wedge block moves downwards along with the 102 rack vertically, the materials are compressed, the inclined surfaces of the 02 wedge block are favorable for dispersing the materials, the bridging state is broken, and the materials smoothly enter the chute.
