Abstract

The utility model discloses a cyclone, which is arranged on the dust-removing device of the exhaust gas of the sintering machine of the sintering plant of the iron and steel company. The cyclone is used for the dust removal of the exhaust gas of the head section and the tail section of the sintering machine and the dust removal of the waste heat utilization. The utility model comprises a cyclone, a guide, and a guide pipe. The cyclone is characterized in that an air pipe can pass through the guide through inserting and pulling and extends into the hollow cavity of the cyclone; the upper end edge of the cyclone is provided with the convex table of the cyclone which is fixed with the lower supporting plate of the dust-removing device. The cyclone can shorten the maintaining, the repairing, the replacing, and the cleaning periods of the cyclone; the processing precision of the air pipe and the guide is improved; the installation of the cyclone does not need filling materials, and accordingly, the weight of the complete set of the dust-removing device is reduced.

Description

Cyclone

The utility model discloses a kind of cyclone, be installed in, be used for the head of sintering machine, the waste gas dedusting of tail and the dedusting of UTILIZATION OF VESIDUAL HEAT IN such as on the equipment of all need to the waste gas dedusting of sintering machine such as iron company's sintering plant.

Existing cyclone all is to place the guider of whirlwind (also claiming urceolus) cavity volume upper end and wireway weldering to be one without any exception, thereby gives the maintenance and the maintenance of whirlwind and clear up grey trowel used for plastering and bring great trouble.For example: when will whole whirlwind or certain several whirlwind of being gathered the cyclone group who constitutes by several cyclones (a common cover cleaner is placed with 36 cyclones that do not wait to 1100 quantity according to different sizes) being overhauled, change, during cleaning, because of can't directly allowing the maintainer enter by last by pulling out wireway, overhaul whirlwind in the space that bottom plate constitutes, change, cleaning, so must open mounting plate, wireway could be pulled out the back together with guide pipe overhauls whirlwind, change, cleaning, thus maintenance can be prolonged, change, cleaning cycle and influence production.Also have, the structure existing problems of whirlwind self cause whirlwind filledly just to be achieved on the bottom plate that stably places cleaner.So not only cause the increase of a whole set of cleaner weight, and be difficult to guarantee the concentricity with wireway.

The purpose of this utility model be to provide the two mounting plate that is connected reasonably, need not to open cleaner of a kind of guider and wireway to pull out wireway and the space that allows the maintenance personal enter to constitute by upper and lower supporting plate to whirlwind implement maintenance, change, cleaning, weak pointization maintenance, replacing, cleaning cycle, the sub-self structure of whirlwind is than rational cyclone.

The purpose of this utility model reaches like this, a kind of cyclone, comprise: whirlwind of sub-through hole 9 of a tool whirlwind and taper ash flue bucket 14 13, is in whirlwind 13 and guider 16, a tool wireway through hole 18 of tool guider through hole 5 and some stator blades 7 and the wireway 4 that communicates with the sub-through hole 9 of whirlwind, and described wireway 4 can pass guider through hole 5 with plugging and stretch into the sub-through hole 9 of whirlwind; Whirlwind 13 upper end edges have a confession its with the mutually solid sub-boss 10 of whirlwind of the bottom plate 12 of cleaner.

The utility model is owing to adopt plug-in to be connected with wireway 4 guider 16, in the time will doing maintenance, replacing, cleaning to all or part of whirlwind 13 that is arranged in the cyclone group on the cleaner, can quickly wireway 4 be pulled out and allow the maintenance personal enter the job space of the upper and lower supporting plate 1,12 of cleaner, so need not open mounting plate 1, thereby can save time, shorten maintenance, maintenance, replacing, cleaning cycle, and because of guider 16 and wireway 4 both separate design, reduced the difficulty in the processing, made machining accuracy and then raising; Owing to be provided with the sub-boss 10 of whirlwind on whirlwind 13, it need not to use filler in addition, thereby can alleviate the weight of a whole set of cleaner on the bottom plate 12 of cleaner the time, and has guaranteed the concentricity with wireway 4.

Below in conjunction with accompanying drawing the utility model is further described below.

Accompanying drawing is the assembly structure figure of the upper and lower supporting plate 1,12 of the utility model and cleaner.

Stator blade 7 of the present utility model has multi-disc, the base portion tool stator blade flange 6 of every stator blade 7.Stator blade 7 is made with the main body one casting of guider 16.When guider 16 being placed whirlwind 13 upper cavity, be in the sub-through hole 9 of whirlwind, the stator blade end face 8 of each stator blade 7 just cooperates with the hole wall of the sub-through hole 9 of whirlwind, dusty gas just can only enter from the surface of stator blade 7, and then the sub-through hole 9 of the whirlwind that enters whirlwind 13 in the shape of a spiral shape, and rotate, make dust sedimentation in whirlwind 13 enter taper ash flue bucket 14, purified gas is then drawn by wireway through hole 18 tops of wireway 4.

The utility model is to be installed on like this on the upper and lower supporting plate 1,12 of cleaner, at first, with the whirlwind stroma hole 11 on the whirlwind 13 plant bottom plates 12, and makes the sub-boss 10 of whirlwind and adds sealing ring 19 and be held on the bottom plate 12.Guider 16 is placed in the sub-through hole 9 of whirlwind again, reach with whirlwind 13 and match.The air guide base hole 2 of the bottom of wireway 4 on the mounting plate 1 of cleaner is inserted through the guider through hole 5 of guider 16 and stretches into the sub-through hole 9 of whirlwind, the top of wireway 4 by connecting plate 3 and add sealing ring 17 usefulness nuts and mounting plate 1 fixing, thereby wireway 4 both was fixed on the mounting plate 1 fully, and guarantees the sealing of 1 of connecting plate 3 and mounting plate.Come by dozens of, up to a hundred and even thousands of the utility model cyclone because a cover cleaner requires according to difference integrated, so in the above described manner each cyclone is installed with mutually with the upper and lower supporting plate 1,12 of cleaner.

It below is the operation principle of the utility model cyclone.Effect by the blower fan of cleaner, dusty gas is just from being entered by the upper and lower supporting plate 1 of cleaner, the opening part in 12 spaces that constituted, stator blade 7 through each cyclone, enter then in each whirlwind 13 and rotate, ash fall is got off until being discharged by ash flue jaws 15, and purified gas is then drawn through wireway through hole 18.Because a cover cleaner need be made of several utility model cyclones, thereby after using a period of time, when will be to 13 maintenance of the whirlwind of all cyclones, cleaning, as long as wireway 4 is all pulled out, make the maintenance personal enter the space of upper and lower supporting plate 1,12 and to the taper ash flue bucket 14 cleaning dust stratifications of whirlwind 13 bottoms or change whole whirlwind 13, and then insert good wireway 4 and get final product; When will be to being arranged in 13 maintenances of one or several whirlwind, the cleaning among the cyclone group on the cleaner or when changing, as long as pull out the wireway 4 of corresponding site, the maintenance slotting good wireway 4 in back that finishes.
