Abstract
A kind of pulverized coal concentrator, include pulverized coal channel and concentration pipeline, it is characterised in that：Described pulverized coal channel is respectively arranged with thick coal culm block and positive stop lug boss with concentration pipeline intersection inner and outer surfaces, described concentration pipeline external surface is arranged to the cylindrical tube that right side carries the conical surface, cylindrical tube inwall right-hand member, which is provided with, is evenly arranged with four thickening blocks, and described concentration inner surface of pipeline is smooth.The utility model is integrally cast using exotic material, and coal dust is entered in concentration channels by pulverized coal channel, the step set by intersection, the thick coal culm in pulverized coal channel is blocked so that thin powdered coal enters concentration channels, so as to realize air-coal separating；Concentration channels outlet temperature is high, and four reinforcements are evenly arranged with exit, extend its service life；Pulverized coal channel inside concentration channels with being arranged to shiny surface, for reducing the friction of coal dust and pipeline, slows down the time of concentration pipe wear, so as to extend its service life, avoids frequent replacing.
Description
Technical field
The utility model belongs to coal burner field, is specifically designed a kind of pulverized coal concentrator.
Background technology
In power boiler breeze burner, to make the distribution of breeze airflow meet the requirement of particular burner design, make
With various pulverized coal concentrator structures.The inspissator portion of hot environment is nearby in for being arranged in burner nozzle
Part, scaling loss situation is easily produced, burner is extremely difficult to preferable effect and overall performance requirement.
Application No. CN201520058701.0 patent discloses a kind of silicon-carborundum ceramic ring, solves mesh
Preceding pulverized coal concentrator needs frequently to change, and influences the technical problem that safety in production also increases production cost.By top windward
The cylinder composition of face round platform, the cylinder at middle part and bottom；The radius of windward side round platform bottom is equal with the radius of middle part cylinder, bottom
The radius of the cylinder in portion is less than the radius of middle part cylinder, and the cylindrical center of windward side round platform, the cylinder at middle part and bottom is along axis
A through hole is run through in direction, and three through holes, three through hole positions are along the circumferential direction uniformly provided with the outer round surface of the cylinder of bottom
Angle between the axial line of same axial location and three through holes is 120 °.This product structure is simple, easy for installation, hard
Degree is high, effectively improves life-span and the performance of pulverized coal concentrator, but when specifically used, because of the high rapid wear of inspissator outlet temperature
It is bad, influence service life.
The content of the invention
The purpose of this utility model provides a kind of pulverized coal concentrator, solves above technical problem.
What the purpose of this utility model was realized in：A kind of pulverized coal concentrator, comprising pulverized coal channel and pipeline is concentrated, its
It is characterised by：It is integrally cast using exotic material, described pulverized coal channel and concentration pipeline intersection inner and outer surfaces point
Thick coal culm block and positive stop lug boss are not provided with, and described concentration pipeline external surface is arranged to the cylinder that right side carries the conical surface
Pipe, cylindrical tube inwall right-hand member, which is provided with, is evenly arranged with four thickening blocks, and described concentration inner surface of pipeline is smooth.
Described pulverized coal channel outer surface, which is provided with to move back, pulls out, and moves back and pulls out angle and be arranged to 3 °.
The cone angle of the described conical surface is arranged to 30 °, and conical surface length is arranged to 190 ~ 200mm.
Described pulverized coal channel left end is provided with five screwed holes.
The utility model is integrally cast using exotic material, and cost is low, reasonable in design, and coal dust passes through pulverized coal channel
Into in concentration channels, by the step of intersection setting, the thick coal culm in pulverized coal channel is blocked so that thin powdered coal enters dense
Contracting passage, so as to realize air-coal separating；Concentration channels outlet temperature is high, and four reinforcements are evenly arranged with exit, are prolonged
Its long service life；Pulverized coal channel, for reducing the friction of coal dust and pipeline, slows down with being arranged to shiny surface inside concentration channels
The time of pipe wear is concentrated, so as to extend its service life, avoids frequent replacing.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
In figure：1st, the conical surface, 2, thicken block, 3, pulverized coal channel, 4, concentration channels, 5, thick coal culm block, 6, positive stop lug boss.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, but not as to limitation of the present utility model：
In the accompanying drawings：A kind of pulverized coal concentrator, include pulverized coal channel 3 and concentration pipeline 4, it is characterised in that：Using resistance to height
Adiabator is integrally cast, and described pulverized coal channel 3 is respectively arranged with thick coal culm with the concentration intersection inner and outer surfaces of pipeline 4
Block 5 and positive stop lug boss 6, coal dust are flowed into concentration pipeline 4 from left end pulverized coal channel 3, because coal dust inertia is more than air, favorably
In forming outer dense interior light concentration distribution feature, thick coal culm block 5 withstands the thick coal culm of the outer end of pulverized coal channel 3, more efficient
Ensure that thin powdered coal enter concentration pipeline 4 in, described concentration pipeline 4 outer surface be arranged to right side with the conical surface 1 cylinder
Shape pipe, cylindrical tube inwall right-hand member, which is provided with, is evenly arranged with four thickening blocks 2, and the intensity of the increase concentration mouth of pipe of pipeline 4 is described
Concentration pipeline 4 and the inner surface of pulverized coal channel 3 it is smooth, reduce coal dust impact when and inspissator frictional force, so as to improve product
Service life.
The described outer surface of pulverized coal channel 3, which is provided with to move back, pulls out, and moves back and pulls out angle and be arranged to 3 °, improves pulverized coal channel 3 and burning
Device connection is more close, reduces the leakage of coal dust.
The cone angle of the described conical surface 1 is arranged to 30 °, and conical surface length is arranged to 190 ~ 200mm, and this structure design is advantageous to light
The burning of coal dust.
The described left end of pulverized coal channel 3 is provided with five screwed holes, and the connection for inspissator and burner is installed.
Above-described embodiment is only intended to clearly illustrate the description that the utility model is made, and not to the limit of embodiment
It is fixed, to those of ordinary skill in the art, other various forms of changes can also be made on the basis of the above description
Or change, there is no necessity and possibility to exhaust all the enbodiments, and the obvious change thus amplified out
Or among changing still in the scope of protection of the utility model.
