Abstract
The invention discloses a reciprocating grate of a biomass boiler, which comprises grate plates, a push-and-pull steel frame, a left base side plate, a right base side plate, riding wheel devices and support frames, wherein the push-and-pull steel frame comprises a left side beam, a right side beam and a plurality of cross beams; a plurality of fixed beams are mounted between the left base side plate and the right base side plate; the riding wheel devices are mounted on the left base side plate and the right base side plate; the left side beam and the right side beam of the push-and-pull steel frame are mounted on the riding wheel device; the cross beams of the push-and-pull steel frame are mutually staggered from the fixed beams on the left base side plate and the right base side plate; the grate plates are mounted on the cross beams and the fixed beams; and the fixed beams are supported on the support frames. According to the technical scheme, the left side beam and the right side beam of the push-and-pull steel frame are supported on the riding wheel devices, and the fixed beams between the left base side plate and the right base side plate are supported on the support frames, so that the whole grate has higher stability and the service life of the grate is guaranteed.
Description
Technical field
The present invention relates to a kind of reciprocal grate of biomass boiler.
Background technology
The reciprocal grate of biomass boiler holds up push-and-pull steelframe by multiple riding wheel apparatus and moves reciprocatingly.For 20 tons of boilers, push-and-pull steelframe is held up by 10 riding wheel apparatus, and each 5 of left and right is arranged symmetrically with, and push-and-pull steelframe is also provided with fire grate segment, riding wheel apparatus then holds up push-and-pull steelframe and fire grate segment come, and moves reciprocatingly under the push-pull effort effect of fire grate reductor.Some fire grate segment is arranged on the built-in beam between the base side plate of left and right, because span is larger between the base side plate of left and right, the temperature again higher built-in beam that fire grate segment is housed easily is crumpled, and even likely causes fire grate to subside.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of rational in infrastructure, biomass boiler reciprocal grate that stability is higher.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of reciprocal grate of biomass boiler, comprises fire grate segment, push-and-pull steelframe, left and right base side plate, riding wheel apparatus, bracing frame; Described push-and-pull steelframe is made up of two, left and right curb girder and Duo Gen crossbeam, between the base side plate of described left and right, many built-in beams is housed, and described left and right base side plate is provided with riding wheel apparatus, and the left and right curb girder of described push-and-pull steelframe is arranged on riding wheel apparatus; Built-in beam on the crossbeam of described push-and-pull steelframe and described left and right base side plate staggers mutually, and described fire grate segment is arranged on crossbeam and built-in beam, and support frame as described above provides support built-in beam.
In technique scheme, the left and right curb girder of riding wheel apparatus to push-and-pull steelframe supports, and bracing frame supports the built-in beam between the base side plate of left and right, so just makes the stability of whole fire grate higher, thus ensure that the service life of fire grate.
Preferably, support frame as described above is A-frame, and this A-frame is made up of a root post, a cross bar and two braces, and described cross bar contacts with built-in beam and coordinates.Due to leg-of-mutton characteristic, so the physical arrangement of this support is very stable, the bearing capacity of built-in beam can be strengthened, alleviate the pressure of riding wheel apparatus.
In one embodiment, described push-and-pull steelframe and bracing frame are made by channel-section steel.
In one embodiment, described push-and-pull steelframe and bracing frame are made by metal side tube.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is push-and-pull steelframe of the present invention and A-frame structural representation.
Detailed description of the invention
The reciprocal grate of a kind of biomass boiler as shown in Figure 1, 2, comprises fire grate segment 1, push-and-pull steelframe 2, left and right base side plate 5, riding wheel apparatus 3, bracing frame 4; Described push-and-pull steelframe 2 is made up of two, left and right curb girder and Duo Gen crossbeam, between described left and right base side plate 5, many built-in beams is housed, and described left and right base side plate 5 is provided with riding wheel apparatus 4, and the left and right curb girder of described push-and-pull steelframe 2 is arranged on riding wheel apparatus 3; Built-in beam on the crossbeam of described push-and-pull steelframe 2 and described left and right base side plate 5 staggers mutually, described fire grate segment 1 is arranged on crossbeam and built-in beam, support frame as described above 4 pairs of built-in beams provide support, support frame as described above 4 is A-frame, described A-frame is made up of a root post, a cross bar and two braces, and described cross bar contacts with built-in beam and coordinates; Described push-and-pull steelframe 2 and A-frame are made by metal side tube.
