Abstract

The utility model provides a five-level flap valve of a rotary cement kiln preheater, which has a good flickering property. The five-level flap valve comprises a valve body, a left valve plate, a left connecting rod, a left valve shaft, a left hammer handle, a left hammer, a right valve plate, a right connecting rod, a right valve shaft, a right hammer handle and a right hammer, wherein a valve opening is formed in the valve body, the left valve shaft and the right valve shaft are respectively arranged at the left side and the right side of the valve body, V-shaped section grooves extending along the axial direction are formed in two ends of the left valve shaft, correspondingly V-shaped section bulges extending along the axial direction are arranged on the valve body below the V-shaped section grooves of the left valve shaft, points of the V-shaped section bulges are upward and are supported on the bottoms of the V-shaped section grooves, and identically, the right valve shaft also has a support structure, and the left valve plate and the right valve plate are jointed in a V shape with an upward opening for jointly closing the valve opening.

Description

Preheater of rotary cement kiln Pyatyi Flap valve

Technical field

The utility model relates to preheater of rotary cement kiln, is specifically related to the Pyatyi Flap valve of preheater of rotary cement kiln.

Background technique

What my company's rotary kiln production line adopted is five-stage whirlwind formula preheater, discharge valve on its Pyatyi blanking pipe is single Flap valve, as depicted in figs. 1 and 2, it comprises valve body 1, valve plate 4, connecting rod 6, valve shaft 2, weight handle 5 and weight 3, valve plate is locked the wind discharging for the valve port that opens and closes valve body with realization, and connecting rod connects valve plate and valve shaft, and valve shaft is arranged at the valve body right side, and two ends are by the UCP212 bearings on valve body, and the valve shaft two ends also configure respectively weight handle and weight.Flap valve plays lock wind, prevents the effect of altering on hot blast, guarantees that again material passes through smoothly, therefore require to have the good property flashed.But the performance of UCP212 bearing is influenced by ambient temperature large, while causing high temperature, single Flap valve can not meet the well requirement of the property flashed, and it is slow to flash, lock wind poor performance, easily putty.

Summary of the invention

The technical problems to be solved in the utility model is to provide the preheater of rotary cement kiln Pyatyi Flap valve that a kind of property flashed is good.

In order to solve the problems of the technologies described above, the technical solution of the utility model is:

A kind of preheater of rotary cement kiln Pyatyi Flap valve, comprise valve body, left valve plate, left connecting rod, left valve shaft, left weight handle, left weight, right valve plate, right connecting rod, right valve shaft, right weight handle and right weight, valve port is set on valve body, and left valve shaft and right valve shaft are separately positioned on the valve body left and right sides;

Left connecting rod connects left valve plate and left valve shaft, left valve shaft two ends are all offered along its axially extended V-arrangement section slot, opening down and its symmetry center face of V-arrangement section slot is crossed left valve shaft axis, accordingly, on the valve body of left valve shaft V-arrangement section slot below, the V-arrangement cross section projection of extending vertically is set, V-arrangement cross section raised tip upward and peak at V-arrangement section slot bottom land, V-arrangement section slot angle be V-arrangement cross section projection angle 4-5 doubly, left valve shaft two ends also all configure left weight handle and left weight;

Right connecting rod connects right valve plate and right valve shaft, right valve shaft two ends are all offered along its axially extended V-arrangement section slot, opening down and its symmetry center face of V-arrangement section slot is crossed right valve shaft axis, accordingly, on the valve body of right valve shaft V-arrangement section slot below, the V-arrangement cross section projection of extending vertically is set, V-arrangement cross section raised tip upward and peak at V-arrangement section slot bottom land, V-arrangement section slot angle be V-arrangement cross section projection angle 4-5 doubly, right valve shaft two ends also all configure right weight handle and right weight;

It is involutory jointly to seal valve port that left valve plate and right valve plate are opening up V-arrangement.

Above-mentioned preheater of rotary cement kiln Pyatyi Flap valve, V-arrangement section slot angle is 90 °, V-arrangement cross section projection angle is 20 °.

Above-mentioned preheater of rotary cement kiln Pyatyi Flap valve, V-arrangement section slot bottom line is a section of corresponding valve shaft axis.

Valve shaft of the present utility model has the V-arrangement section slot, V-arrangement cross section raised tip on valve body is propped up and is peaked at V-arrangement section slot bottom land, valve shaft contacts with V-arrangement cross section salient line, valve shaft can rotate to realize around V-arrangement cross section raised tip the swing of corresponding valve plate, because valve shaft contacts with V-arrangement cross section salient line, and temperature influence not, so the utlity model has the good property flashed, improved the lock wind effect of Flap valve, guaranteed that again blanking is unimpeded.
