Abstract
The utility model discloses a grate, wherein a rotating shaft is arranged in the middle of a base of a furnace body; at least two grate sheets are arranged on the rotating shaft; at least one coal poking block is arranged at the external sides of the grate sheets; a first outlet and a second outlet are arranged on the two sides of the base respectively and are communicated with a coal box; a motor is mounted on the base and is connected with the rotating shaft through a driving device; a hollow cavity is arranged in the rotating shaft and is connected with an air supply pipe; and air outlets are arranged on a side wall of the rotating shaft and between the adjacent grate sheets. The utility model has the advantage that the grate with a reasonable structure can solve defects existing in the existing art, and can turn over coal balls when the dried coal balls are cooled, improve the cooling effect, prevent the coal balls from burning and improve yield.
Description
Technical field
The utility model relates to moulded coal manufacturing installation field, specifically is a kind of fire grate.
Background technology
Along with expanding economy, coal increases fast as a kind of important energy demand.In moulded coal was produced, the oven dry of wet bulb cooling was crucial operation.In the existing moulded coal drying oven, the coal briquette after the oven dry is fallen on the rigid grate and is lowered the temperature, and the coal briquette after the cooling is discharged by discharging opening.Existing fire grate all can't stir coal briquette in temperature-fall period, the efficient that causes lowering the temperature is low, the easy burning of coal briquette etc.
The utility model content
The purpose of this utility model provides a kind of fire grate, and it can be used to dry moulded coal, when can be after oven dry coal briquette being lowered the temperature, stirs coal briquette and rotates, and temperature with high efficiency prevents that coal briquette from so burning.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of fire grate, at the base of furnace body middle part rotating shaft is installed, at least two fire grate sheets are installed in the rotating shaft, at least one dials coal cinder fire grate sheet arranged outside, the base both sides are provided with first discharging opening and second discharging opening, first is provided with discharging opening and second discharging opening is communicated with the coal breakage case, motor is installed on the base, motor is connected with rotating shaft by drive unit, is cavity in the rotating shaft, and cavity is connected with air supply pipe, set out gas port on the rotating shaft sidewall, the gas outlet is between adjacent fire grate sheet.
Advantage of the present utility model is: can solve the deficiency that exists in the known technology, and rational in infrastructure, can when the cooling of coal briquette oven dry back, stir coal briquette, improve cooling-down effect, prevent the coal briquette burning, improve yield rate etc.

Label shown in the accompanying drawing: 1, discharging opening; 2, base; 3, motor; 4, rotating shaft; 5, cavity; 6, gas outlet; 8, dial coal cinder; 9, fire grate sheet; 10, air supply pipe; 11, second discharging opening.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within equally please appended claims institute restricted portion in this.
A kind of fire grate described in the utility model, agent structure are included in base of furnace body 2 middle parts rotating shaft 4 are installed, and at least two fire grate sheets 9 are installed in the rotating shaft 4, and described fire grate sheet 9 can be provided with multi-disc as required, and 7-10 sheet fire grate sheet for example can be set.At least one dials coal cinder 8 every layer of fire grate sheet 9 arranged outside, general preferably dials coal cinders 8 evenly being provided with 4 on fire grate sheet 9 circumference, dials coal cinder 8 and can fully stir coal briquette roll in rotation, dries.First discharging opening 1 is set in base 2 both sides and second discharging opening 11, the first is provided with discharging opening 1 and second discharging opening 11 is communicated with the coal breakage case, and the coal briquette after the oven dry cooling is dropped out by first discharging opening 1 and second discharging opening 11, enters the coal breakage case.Adopt the two discharge holes structure, can improve coal breakage efficient, prevent that coal briquette from stopping up discharging opening, motor 3 is installed on base 2, and motor 3 is connected with rotating shaft 4 by drive unit, and motor 3 drives rotating shaft 4 and rotates, thereby driving fire grate sheet 9 rotates, coal briquette is at fire grate sheet 9 and dial under the drive of coal cinder 8 constantly upset on fire grate sheet 9, realization cooling.In the described rotating shaft 4 is cavity, and rotating shaft 4 is connected with air supply pipe 10, sets out gas port 6 on rotating shaft 4 sidewalls, and gas outlet 6 is between adjacent fire grate sheet 9.Air supply pipe 10 to 9 ejections of fire grate sheet cold air, is given the coal briquette cooling of oven dry back by the gas outlet in the rotating shaft 46.
