Technical Field

The invention relates to the technical field of boiler equipment, in particular to a boiler grate.

Background

In the existing boiler, a horizontal grate is arranged in a hearth, and fuels such as coal and the like are put on the grate to be combusted, so that hot air generated during combustion rises to heat water in the boiler. The coal of the traditional boiler is static on a fire grate and does not move when being combusted, the coal at the central part is only contacted with oxygen through ash slag, the problems of insufficient coal combustion, low thermal efficiency, large energy consumption, more waste gas and serious dust pollution are easily caused, and the requirements of environmental protection and energy saving are not met;

fire grates, namely fire grates, are required to be used in boiler equipment, the existing fire grates are all formed by fixing row pieces or ribs on an integral frame, and if a single row piece or rib is damaged, the fire grate needs to be replaced completely, so that raw materials are wasted; and the existing fire grate is mostly made of cast iron, is not high-temperature resistant, is easy to melt and damage when the temperature is overhigh, and has short service life.

The lower side of the fixed grate is provided with a rotating ball, and the fixed grate can rotate around the rotating ball.

The top of the fixed grate is provided with a fixed groove, one surface of the movable grate, which is in contact with coal, is a plane, the other surface of the movable grate is a slope, one end of the movable grate is provided with a clamping angle, and the clamping angle is matched with the fixed groove so that the fixed grate is horizontally arranged.

Wherein, a sliding groove is arranged on one side of the movable frame, a rolling shaft is arranged on the furnace wall, and the rolling shaft penetrates through the sliding groove to be matched with the movable frame.

The movable grate and the fixed grate are in a horizontal state; the movable frame forms an included angle with the horizontal direction.

The invention has the beneficial effects that: the boiler grate has the advantages that the structure is simple, the operation is convenient, the grate surface is kept horizontal by adjusting the supporting bolts on the idler wheels, fuel can be uniformly distributed and uniformly combusted on the grate surface, the movable grate and the fixed grate are driven to alternately move in a staggered manner by the movable frame, and therefore, slag is discharged efficiently.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise. The relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself. Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and the terms have no special meanings unless otherwise stated, and therefore, the scope of the present invention should not be construed as being limited.
