Abstract
A high-efficiency pulverized coal equipartition device comprises a base, a spray gun, an inner cavity, a plurality of distribution branch pipes, an inverted cone, a top cover, a hanging ring and a lining plate, wherein the base is welded on the lower portion of a spray gun communicated with the inner cavity, the distribution branch pipes are welded on the inner cavity, the inverted cone is welded at the top of the inner cavity, the top cover is riveted at the top of the inner cavity, the lining plate is welded in the middle of the inner cavity, the hanging ring is welded on the upper portion of the top cover, and the top angle of the inverted cone is a right angle. The high-efficiency pulverized coal equipartition device is even in pulverized coal distribution, low in resistance loss, not easy to block, convenient in blocking treatment and inverted cone replacement, wear-resistance, long in service life and capable of preventing pulsation of solid gas flow.
Description
Technical field
The utility model relates to divider, is specially efficient coal dust divider.
Background technology
At present, generally adopt divider that two kinds of forms are arranged in the pulverized coal injection powder craft: a kind of is the bevel-type divider, and another kind is a bottle formula divider, and the coal dust that pulverized coal distributor is carried the coal powder injection house steward is assigned to each air port of blast furnace equably.Assignment accuracy is high more, and the chance that divider arm and spray gun stop up is just more little.Traditional divider uses more, but there is following weak point in it: 1, the distribution cavity capacity of general bevel-type divider is less, and the height of its distributed uniform degree mainly is the taper of handstand, general bottle formula divider by the top, chamber, the distribution cavity volume is bigger, and the top does not have the back taper of secondary distribution; 2, inner cone is fixed, and can't clear up after being stopped up by coal dust; 3, the inner chamber airflow fluctuation is big, easily causes the pulsation phenomenon of solid and gas stream; 4, inner cone is easily caused the distribution effects variation by the wearing and tearing of high speed solid and gas stream, and work-ing life is short.
The utility model content
The technical problem that the utility model solved is to provide efficient coal dust divider, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
Efficient coal dust divider, comprise base, spray gun, inner chamber, dispensing branch, back taper, top cover, link and liner plate, described base is welded on the bottom of spray gun, described spray gun and intracavity inter-connection are welded with a plurality of dispensing branch on the described inner chamber, the welded top of described inner chamber has back taper, the top riveted joint of described inner chamber has top cover, the middle part of described inner chamber is welded with liner plate, and the top of described top cover is welded with link, and the drift angle of described back taper is the right angle.
Beneficial effect
On the utility model structure " bevel-type divider " and " bottle formula divider " are combined, the back taper of secondary distribution is set up at distribution cavity top at bottle formula divider, the coal dust that enters the divider chamber is all assigned in the every arm, simultaneously the fixed cone structural reform is survived the mantle body, in case wearing and tearing are convenient to change, and increase the service life.In cavity upper strata body bottom inner cone installing port, inner cone being arranged is the activity cone, and upper periphery has outstanding installation limit, by bolt it is movably arranged on the installation limit on the installation limit of body, by bolt it is movably arranged on the installation step on installation limit of body, owing to adopt above texture improvement, coal dust distributed uniform, resistance is decreased little, be difficult for obstruction, prevent the pulsation phenomenon of solid and gas stream, stop up and handle, change inner cone conveniently, wear-resistant, long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
For technique means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the structural representation of efficient coal dust divider, efficient coal dust divider, comprise base 1, spray gun 2, inner chamber 3, dispensing branch 4, back taper 5, top cover 6, link 7 and liner plate 8, described base 1 is welded on the bottom of spray gun 2, described spray gun 2 is connected with inner chamber 3, be welded with a plurality of dispensing branch 4 on the described inner chamber 3, the welded top of described inner chamber 3 has back taper 5, the top riveted joint of described inner chamber 3 has top cover 6, the middle part of described inner chamber 3 is welded with liner plate 8, and the top of described top cover 6 is welded with link 7, and the drift angle of described back taper 5 is the right angle.
During use, coal dust enters into inner chamber 3 from spray gun 2, divides equally for the first time in inner chamber 3, finishes when touching back taper 5 then for the second time and distributes, and can reach the purpose of efficiently dividing equally like this.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model; the technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
1. efficient coal dust divider, comprise base, spray gun, inner chamber, dispensing branch, back taper, top cover, link and liner plate, it is characterized in that, described base is welded on the bottom of spray gun, described spray gun and intracavity inter-connection, be welded with a plurality of dispensing branch on the described inner chamber, the welded top of described inner chamber has back taper, and the top riveted joint of described inner chamber has top cover.
2. efficient coal dust divider according to claim 1 is characterized in that the middle part of described inner chamber is welded with liner plate, and the top of described top cover is welded with link.
