Abstract
The utility model discloses a blast furnace coal injection distributor sweeps buggy debris collection device, the device includes: the air inlet end of the corner type dust collecting cover is arranged on the air outlet of the distributor in a matching way; the collecting cloth bag is arranged on the air outlet end of the corner type dust collecting cover in a matching way through a fixing piece. The utility model discloses can solve current distributor and sweep the inside buggy of in-process defeated powder pipeline and distributor and can fly away everywhere, cause environmental pollution and the problem that the unorganized emission incident takes place.
Description
Technical Field
The utility model relates to the technical field of metallurgy, in particular to a pulverized coal sundries collecting device for a blast furnace coal injection distributor.
Background
The blast furnace blowing coal powder is pulverized anthracite powder or bituminous coal powder or mixed coal powder of the two which is directly blown into the blast furnace from a blast furnace tuyere so as to replace coke and play the role of providing heat and reducing agent, thereby reducing the coke ratio and the pig iron cost. Blast furnace coal injection is a revolutionary and important measure for modern blast furnace ironmaking technology. It is a key technology for the continuous survival and development of whether blast furnace iron making can compete with other iron making methods. The blowing mode can be divided into two main types, namely a multi-pipeline mode and a single-pipeline plus distributor mode. The configuration of the powder making and injection facilities is divided into a direct injection mode in which the powder making and the injection are combined together to directly inject the coal into the blast furnace and an indirect injection mode in which the powder making and the injection facilities are separated, the coal powder is sent to an injection station close to the blast furnace from a powder making workshop through a tank car or a pneumatic conveying pipeline, and then the coal powder is injected into the blast furnace. The existing production mode is that one coal injection supplies a blast furnace No. 1, two coal injection supplies a blast furnace No. 3-6, three coal injection supplies a blast furnace No. 7, and the surplus coal powder of the two and three coal injection is conveyed to an injection station through a pipeline to supply a blast furnace No. 2. The method is characterized in that the method is influenced by the conditions of raw coal transportation, feeding and distribution, impurities are mixed in the raw coal, part of the impurities enter an injection system along with the coal powder in the process of grinding the coal powder by a coal pulverizing system, the coal powder is finally injected into a blast furnace through a distributor, the impurities cannot enter the blast furnace through the distributor in the process, the impurities can block or remain in the distributor, the distributor needs to be uncovered and purged during the damping-down maintenance of the blast furnace after the distributor operates for a period of time, the internal impurities are cleaned, and a powder conveying pipeline and the coal powder in the distributor can float around in the purging process of the distributor, so that the environmental pollution and the unorganized emission event are caused.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a coal injection distributor of blast furnace sweeps buggy debris collection device.
In order to achieve the above object, the technical solution of the present invention is specifically as follows:
the utility model provides a blast furnace coal injection distributor sweeps buggy debris collection device, includes:
the air inlet end of the corner type dust collecting cover is arranged on the air outlet of the distributor in a matching way;
the collecting cloth bag is arranged on the air outlet end of the corner type dust collecting cover in a matching way through a fixing piece.
The corner formula dust cage includes:
a bell housing;
and the air inlet end of the L-shaped pipe is matched and arranged at the top of the bell-shaped cover body.
The bell-shaped cover body is arranged on the air outlet of the distributor in a matching way through a flange plate.
And a baffle ring is arranged on the outer edge of the air outlet of the L-shaped pipe and used for preventing the collecting cloth bag from separating from the L-shaped pipe.
The fixing piece is a hoop.
The utility model has the advantages that: the utility model provides a buggy, debris when the distributor sweeps problem that wanders away everywhere, stopped environmental pollution and the emergence of inorganization emission incident, improved the efficiency that blast furnace system overhauld. The utility model discloses pass through the ring flange with the bell jar body and be connected with the distributor in the field usage process, the distributor sweeps the in-process and collects buggy, debris through collecting the sack, and debris and buggy fall back the distributor can be avoided to the structure of L venturi tube, and the tip sets up fender ring and staple bolt, prevents to collect the emergence that the sack drops the incident in the use, will after sweeping the end the utility model discloses demolish, resume the distributor.
