Abstract
The utility model belongs to the field of equipment of a coal spraying system for a blast furnace, particularly a separator for separating fibrous impurities such as wood dust in powdered coal in a pipeline of an outlet of a middle-speed grinding mill. A dummy club is arranged at the top end of a shell body of the separator. A V-shaped compounded mesh screen is arranged in the shell body of the separator. A rectangular flange of a rectangle type impurity discharging hole, an impurity discharging hole covering plate, pressing wedge-shaped iron and a bolt are orderly arranged at the top part of the V-shaped compounded mesh screen. A sealing rubber strip is arranged between the rectangular flange and the impurity discharging hole covering plate. The utility model has the advantages of good impurity separating effect, simple structure, small resistance, good sealing effect and convenient cleaning, wherein the one-time filtering-out rate of the impurities of a V-shaped separator is more than 80%.
Description
Technical field
The utility model belongs to the apparatus field of bf coal injection system, and particularly middling speed grinding machine outlet conduit separates the separator of fibrous foreign material such as wood chip in the coal dust.
Background technology
In the prior art, medium-speed pulverizer is one of capital equipment of bf coal injection system, because its good airproof performance, the equipment noise is little and power consumption is low, becomes the first-selected powder manufacturing apparatus that substitutes ball mill gradually.But the part that rolls of medium-speed pulverizer is arranged in the same structure with the powder selecting part branch, makes and can't be discharged smoothly by air-flow by original-shape as light weight sundries in the coals such as wooden unit, grass roots.The foreign material that these can directly separate by air-flow, can only be rolled into could be by the mill separator on top after thread or fibrous, is carried by air-flow with coal dust and enters the grinding machine outlet conduit.Unimpeded for guaranteeing the winding-up pipeline, reduce and stop up, the fibrous foreign material in the coal dust can only be removed by equipment such as vibratory sieve, coal dust filters at present.
Vibratory sieve is a pulverized coal sieve subset commonly used, and it generally is installed in the bottom of cloth bag collection machine or the top of Pulverized Coal Bin.There are the following problems for vibratory sieve in practicality: 1. sealing is poor, runs the powder phenomenon and is difficult to stop; 2. vibrating noise is big; 3. need corollary equipments such as flapper, rotary feeder.Coal injection system has not only been simplified coal injection system as the cancellation vibratory sieve, also can reduce the environmental pollution of internal system simultaneously.
The coal dust filter also is the common equipment of foreign material in the filtering coal dust, generally is installed on the winding-up pipeline, and it is irreplaceable as last one filter plant that guarantees smooth and easy winding-up.But too much as foreign material in the coal dust, dismantle too frequently, then labour intensity is big, and equipment loss is serious, to stablizing winding-up certain influence is arranged also.
The utility model content
The purpose of this utility model is to provide a kind of impurity good separating effect, device structure is simple, equipment resistance is little, good sealing effect, make things convenient for the coal dust sundries separator of foreign material cleanings.
According to above-mentioned purpose operation principle of the present utility model is that grinding machine is exported to wind speed in the cloth bag collection machine pipeline up to 15-25m/s, is to utilize material speed poor, separates the prime location of fibrous foreign material in the coal dust.The utility model is welded on the grinding machine outlet conduit (raise 45 ° at angle or 90 °), and utilize built-in V-shape composite screen mesh portions to separate foreign material (mainly being fibrous foreign material) in the coal, thereby reduce the disassemble and assemble work amount of coal dust filter, and the held stationary winding-up.
According to above-mentioned order solution of the present utility model be:
This shell separator top is provided with boss, the compound screen cloth of V-arrangement places in the shell separator, the compound screen cloth of V-arrangement places in the shell separator, the top of the compound screen cloth of V-arrangement is the rectangular flange, the sediment flushing outlet cover plate that are provided with rectangle type sediment flushing outlet successively, compresses wedge shape iron and bolt, is provided with sealing rubber strip between rectangular flange and the sediment flushing outlet cover plate.Other solution of the present utility model is: the compound screen cloth of V-arrangement of air inlet one side of coal dust is a blind window, and blind window is for leaving state during operation, and blind window is an off status when assorted clearly; The compound screen cloth of V-arrangement of gas outlet one side of coal dust is a fine screen mesh, and its hole shape is a circular hole, average pore size 8-10mm.
Fine screen mesh in the compound screen cloth of V-arrangement is 20-30 ° to the angle [alpha] of the direction vertical tilt of coal dust gas outlet.
The part that the compound screen cloth of V-arrangement is hidden only accounts for the 60-70% of grinding machine outlet conduit sectional area, and is positioned at the top of tilted tube.
The utility model compared with prior art has the impurity good separating effect, device structure is simple, equipment resistance is little, the advantage of good sealing effect, easy cleaning.The utility model adopts special construction, and equipment resistance is little, good airproof performance, easy cleaning, no additional power consume, and with the supporting use of coal dust filter, can leach in the coal dust all thread or block foreign material, guarantees the unimpeded of winding-up pipeline.Wherein the foreign material of V-arrangement separator once leach rate＞80%.
