Abstract
The utility model discloses a kind of Pulverized Coal Bin activation cone, it is provided with the Pulverized Coal Bin bottom multiple in funnel shaped coal dust discharge bucket, the activation cone is arranged in coal dust discharge bucket, what the activation cone was annular with formation between corresponding coal dust discharge bucket goes out coal channel, have at regular intervals between the activation cone and the discharging opening of coal dust discharge bucket, the activation cone is connected with Pulverized Coal Bin by connector.By this utility model being arranged in the coal dust discharge bucket of Pulverized Coal Bin, rat hole stream, arching and avalanche phenomenon that coal dust occurs when drawing off can be prevented effectively from, so that coal dust forms overall flow in most of region, so as to ensure pulverized coal flow stably into the powder feed system of boiler.
Description
Technical field
This utility model belongs to power plant's powder manufacturing apparatus technical field, the activation in more particularly to a kind of Pulverized Coal Bin for power plant
Cone.
Background technology
In power industry, feed coal is sent to Pulverized Coal Bin storage Jing after ball mill grinds.By Pulverized Coal Bin machine supplying powder handle
Coal dust sends into the powder feed system of boiler.
In the structure design of existing Pulverized Coal Bin, it is stainless that although the discharge outlet of Pulverized Coal Bin takes steep-taper funnel, liner
Steel, polish smooth and the measure such as angle of cut rounding, but some Pulverized Coal Bins still occur rat hole stream, arching and avalanche phenomenon, from
And cause the coal dust for sending into boiler erratic, the problems such as some time coal dust cannot draw off occurs even sometimes, pot is caused
Stove hearth combustion is unstable.
Utility model content
Goal of the invention of the present utility model is：For above-mentioned problem, there is provided one kind can make pulverized coal flow steady
Surely into the Pulverized Coal Bin activation cone of boiler powder feed system.
What the technical solution of the utility model was realized in：Pulverized Coal Bin activation cone, is provided with the Pulverized Coal Bin bottom
It is multiple in funnel shaped coal dust discharge bucket, it is characterised in that：It is described activation cone be arranged in coal dust discharge bucket, it is described activation cone with
Annular is formed between correspondence coal dust discharge bucket goes out coal channel, has one between the activation cone and the discharging opening of coal dust discharge bucket
Determining deviation, the activation cone are connected with Pulverized Coal Bin by connector.
Pulverized Coal Bin activation cone described in the utility model, its described activation cone is in square taper or cone.
By being arranged on this utility model in the coal dust discharge bucket of Pulverized Coal Bin, coal dust can be prevented effectively from and when drawing off
Existing rat hole stream, arching and avalanche phenomenon so that coal dust forms overall flow in most of region, so as to ensure that pulverized coal flow is steady
Surely into the powder feed system of boiler.
Description of the drawings
Fig. 1 and Fig. 2 are internal structure schematic diagrams of the present utility model.
Labelling in figure：1 is Pulverized Coal Bin, and 2 is coal dust discharge bucket, and 3 are activation cone.
Specific embodiment
Below in conjunction with the accompanying drawings, this utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only to explain
This utility model, is not used to limit this utility model.
As shown in figure 1, Pulverized Coal Bin activation cone, is provided with 1 bottom of the Pulverized Coal Bin multiple in the discharging of funnel shaped coal dust
Bucket 2, the activation cone 3 are arranged in coal dust discharge bucket 2, form annular between the activation cone 3 and corresponding coal dust discharge bucket 2
Go out coal channel, between the activation cone 3 and the discharging opening of coal dust discharge bucket 2, have at regular intervals, the activation cone 3 is by connection
Part is connected with Pulverized Coal Bin 1, wherein, in square taper or cone, upward, the activation bores 3 to the cone 3 that activates on its summit
The conical surface cooperatively forms section in funnel shaped circular passage with the inwall of corresponding coal dust discharge bucket.
In the present embodiment, an activation cone is provided with above the discharging opening of each coal dust discharge bucket, actually used
In, can be according to the coal dust physical property of actual measurement（Mainly angle of repose and compactibility）With the version of Pulverized Coal Bin, determine that setting is lived
Change the quantity of cone and calculate the size of the height and activation cone that determine that appropriate activation cone separates out material mouth.
Preferred embodiment of the present utility model is the foregoing is only, it is not to limit this utility model, all at this
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in this utility model
Protection domain within.
