Description

Preheater link plate formula inner core

Technical field

The utility model relates to the tripping device of the raising separation efficiency that is used for new type nonaqueous cement production line cyclone preheater system, is specially a kind of preheater link plate formula inner core.

Background technology

The whirlwind tube is the major parts of cyclone preheater, and it mainly finishes separating of material and gas.In order to reach 80～90% separation efficiency, it is essential that inner core is set in the middle.C3～C5 inner core long term operation is in etchant gas media such as containing alkali, sulphur, chlorine and surrounds down 650～920 ℃ hot environment, and therefore being convenient to damage split blade type (the being the link plate formula) inner core of changing the back becomes the first-selection of design.Burst is made, and the burst transportation is being used the on-the-spot assembled formation that hangs again.During the assembling of existing link plate formula inner core, link plate need adopt means such as welding to fix, and is inconvenient to change; Articulate part and be exposed in the corrosive environment, work-ing life is short.

Summary of the invention

The technical problems to be solved in the utility model is: existing link plate formula inner core assembly and disassembly inconvenience and work-ing life are short.

The utility model comprises fixed block, inner core link plate, gusset plate from top to bottom, fixed block exports on the flange that stretches out by the whirlwind tube that the joint bolt pair is fixed on cyclone preheater, it is characterized in that fixed block, inner core link plate and gusset plate all are circle distribution, the inner core link plate is at least one deck, adjacent up and down between the two-layer inner core link plate circumferential misalignment link to each other, fixed block and gusset plate are respectively applied for last layer inner core link plate and basecoat inner core link plate are connected as a single entity.

More firm in order to connect, fixed block all adopts circumferential misalignment to link to each other with last layer inner core link plate, gusset plate with basecoat inner core link plate.

Link plate of the present utility model need not weld the outer means of single-candidate when assembling, assemble, dismantle easy; Its whole service life prolongs.

Embodiment

Referring to each accompanying drawing, the utility model by last, neutralization down three parts forms: top is fixed on the whirlwind tube by a circle with the joint bolt pair and exports the fixed block that stretches out flange and form, the middle part is made up of some joint inner core link plates, joint number is determined that by inner diameter of steel flue and length the bottom circumferentially is unified into an integral body by gusset plate with each inner core link plate.Adopt hook directly to connect between fixed block and inner core link plate and inner core link plate, the scene need not to weld, as Fig. 1, Fig. 2, Fig. 3.

Fixed block of the present utility model (3) is provided with groove (3-1) (referring to Fig. 4).Inner core link plate (4) one ends are provided with two hooks (4-1), and an end is groove (4-2), and hook (4-1) and groove (4-2) are positioned at the not coplanar (referring to Fig. 5) of inner core link plate (4).Fixed block (3) and inner core link plate (4), directly connect by hook (4-1) and groove (3-1 and 4-2) between inner core link plate (4) up and down, hook (4-1) is fastened in the groove (3-1 and 4-2), corresponding position in the groove (3-1 and 4-2) is provided with block (3-2 and 4-3), retaining is in the both sides of hook (4-1), prevent that the circumferential string of link plate when fastening state is moving, cause the inhomogeneous of each sheet hoop gap.Circumferential misalignment links to each other between the adjacent two rows inner core link plate (4), to form the integral cylinder shape, prevents loose (referring to Fig. 1, Fig. 2).And; because the hook (4-1) of inner core link plate 4 is hidden in the groove (3-1 and 4-2) fully; make hook (4-1) engage the position and form a horizontal section (X) with groove (3-1 and 4-2); like this; material in the inner core can deposit and glue to be paid on horizontal section; thereby the part that articulates to the inner core link plate plays a protective role, and prevents to link up with the corrosion and the wearing and tearing at position, prolongs the work-ing life of parts.

Link plate formula inner core uses gusset plate (5) to be stuck in the groove (4-2) of link plate bottom, and inner core link plate (4) is circumferentially linked up, in case the not-go-end mouth is loose, makes it into as a whole.
