Description
Technical field
The present invention relates to coal dust kiln coal powder distribation technical field, specifically a kind of floating bevel-type coal powder distribation
Device.
Background technology
At present, coal powder distribation device used in coal dust kiln is all come balanced each spray gun coal powder injection by manual adjustment pulverized coal gun
Amount.Manual adjustment causes each spray gun injecting coal quantity unavoidably.And the spray gun distribution coal dust of coal dust kiln is uneven, each spray can be caused
The heated situation of rifle point lime is uneven, the lime burning caused, some lime raw burns, influences the quality of production.
The content of the invention
Present invention aim to provide a kind of floating cone type coal powder distributor, it can solve coal dust kiln spray gun injecting coal quantity not
The problem of balanced, so as to improve product quality.
What the present invention was realized in：
Floating cone type coal powder distributor, including conical distributor housing, conical distributor top cover, positioned at the conical distributor
Floating cone in housing, it is installed on some distribution pipes that edge is pushed up in conical distributor housing sidewall and is installed on the conical distributor
The floating cone detent mechanism for being used to adjust floating cone position on device top cover；The floating cone detent mechanism includes being connected to the taper point
The elevating lever of orchestration top cover through hole, the lifting nut for being bolted in the elevating lever top and it is bolted in the smooth of elevating lever end
Brake pad, top surface is provided with caulking groove on the floating cone, and the brake pad is located in the caulking groove and rotated with floating taper into sliding；Institute
State lifting nut and be fixed on the distributor top cover.
Of the invention to use this structure, coal dust is entered by the gap between floating cone and housing to be pushed up along uniform along housing
Distribution pipe.Equal gap make it that the coal dust amount that each distribution pipe is assigned to is equal.When side clearance change is big, the center of gravity for floating cone is inclined
Move, and under gravity, the self-return function of center of gravity causes the floating spontaneous generation centripetal force of cone, so that the center of gravity of floating cone is extensive
Multiple position of center line, so, floating cone is attributed to again with the gap between housing to be equal, and then each distribution is in control the equal of equivalent
The coal dust of even distribution.When the change because of flow velocity causes coal dust to evenly distribute, near the larger distribution pipe of coal dust flow velocity
Coal dust can become big to the thrust of floating cone, promote floating cone to be rotated about to low flow velocity distribution pipe, while drive coal dust to low flow velocity point
A pipe arrangement shunting part, as a result, the pulverized coal conveying amount of the big distribution pipe of the pulverized coal conveying amount is gradually decrease to normal equilibrium
State.
The present invention can be very good solve the problems, such as that each lance combustion of coal dust kiln is uneven, coal dust kiln sodalime is heated
The problem of uneven, is addressed, and improves the product quality of lime, lowers raw burning rate, improves the yield of high-quality ash, from
And effectively improve economic benefit.
Under above-mentioned technical proposal, the present invention can be achieved in that：
The distribution pipe is 16.
The present invention adds floating wimble structure on original distributor, can so ensure to work as one of them or several pipe arrangements
When conveying quantitative change is big, acted on by the rotation of floating cone or by its own gravity, realization is automatically adjusted so that remaining distribution pipe
Powder sending quantity uniformly reduce, thus avoid the influence to remaining 15 spray gun running status when adjusting a spray gun.So that
The distributor can realize the flame situation for automatically adjusting each spray gun in coal dust kiln production process, solve each spray of coal dust kiln
The coal powder distribation inequality problem of rifle.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Exemplary explanation is carried out to the present invention below in conjunction with the accompanying drawings, but any restrictions are not formed to the present invention
Shown in Fig. 1, floating cone type coal powder distributor includes conical distributor housing 1, in the conical distributor housing
Floating cone 2, be installed in conical distributor housing sidewall push up edge some distribution pipes 6 and be installed on conical distributor top cover 5
On the floating cone detent mechanism for being used to adjust floating cone position.It is open-minded that floating cone detent mechanism includes being connected to institute on distributor top cover 5
Elevating lever 4, the lifting nut 7 for being bolted in the top of elevating lever 4 and the smooth brake pad 3 for being bolted in elevating lever end in hole.
Top surface is provided with caulking groove on floating cone 2, and brake pad 3, which is located in caulking groove and formed with floating cone 2, slides rotation.In the present invention, brake pad 3 with
The structure of caulking groove, a kind of achievable mode are after brake pad 3 inserts the notch of floating cone 2, pass through fastener in 2 top surfaces of floating cone
Spacing pad is connected to, to carry out longitudinal spacing to brake pad 3.Distributor top is fixed on the spacing lifting nut 7 that elevating lever 4 is spirally connected
Lid 5.Distribution pipe 6 is located at distributor body internal face, and along the upper top of distributor body along uniform, its number is arranged as required to,
It is 16 in present embodiment.
Coal dust enters in distributor body 1 from lower flange mouth, passes through the gap uniformity point between floating cone 2 and distributor body 1
16 distribution pipes 6 of dispensing, spray gun is then sent into by the flexible pipe connected with distribution pipe 6.
In the present invention, lifting nut position is fixed, and force rotates elevating lever 4, and it carries out upper and lower shifting while rotation
Position.When elevating lever 4 shifts, being bolted in the brake pad 3 of its end can also drive floating cone 2 to move up and down, so as to by adjusting floating cone
Gap between distributor body adjusts the total conveying capacity of coal dust flow velocity i.e. coal dust, and then adjusts the pulverized coal flow of distribution pipe 6.
Smooth brake pad 3 is inlayed inside floating cone 2, brake pad 3 can form with floating cone 2 and slide rotation, and thus, floating cone can
With under coal dust thrust automatic rotary modulation economize on coal powder flow rate, so as to adjust the conveying capacity of each distribution pipe coal dust.
The present disclosure additionally applies for technological improvement is carried out to existing coal dust kiln spray gun injecting coal quantity device, to solve in production process
The problem of spray gun injecting coal quantity inequality.
Advantage major embodiment of the present invention is in the following areas：Pass through the lifting and the balanced each distribution of rotational automatic regulation of floating cone
Coal dust amount between pipe, make the heat of 16 spray guns of kiln body surrounding identical, improve the temperature equalization in kiln, improve the equal of lime
The heated situation of weighing apparatus, reduce lime due to uneven heating weighing apparatus caused raw burn-off phenomenon.The each spray gun spray of coal dust kiln can be ensured
The balanced longtime running of coal amount, makes coal dust kiln spray gun injecting coal quantity adjust automatically, obvious through test effect.
