Abstract
The invention discloses a stepped cover board type valve for a tunnel drying hole hot air flue, which comprises regulating flashboards which are arranged at an inlet and an outlet of a hot air flue and are stepped bases and grid plates, wherein the stepped bases are built up with refractory bricks along the two side walls of the hot air flue, and grid plates are horizontally arranged between two bases in turn along each step top of the bases; each grid plate is provided with a movable baffle plate, and the movable baffles arranged on the grid plates along the step tops can form an inclined grate after being obliquely installed. The stepped cover board type valve has the advantages that the service life of valves at the inlet and the outlet of the hot air flue can be prolonged, if certain movable baffle is broken and affects the temperature regulation, the broken movable baffle can be replaced solely, thus the waste of steel material is reduced, the smooth flow of the whole procedure production is ensured, the production efficiency is improved, and the product quality is guaranteed.
Description
Technical field
The present invention relates to the used tunnel drying hole of refractories industry, especially relate to a kind of tunnel drying hole hot air flue ladder cover board type valve.
Background technology
At refractories industry, the tunnel drying hole is mainly used in various materials of oven dry or base substrate, because the temperature difference that needs during drying materials, need constantly to adjust, temperature controlled method generally is at place, the hot blast branch flue gateway at two ends, dry hole a rotating metallic flashboard to be installed respectively, utilizes the flow of the size adjustment hot blast of the metal flashboard anglec of rotation to control the height of temperature in the dry hole.But often because intake air temperature is too high makes metallic plate distortion and can not use for a long time, for satisfying the production demand, can only constantly change flashboard in practical operation, the time-consuming material that takes has again seriously restricted the operation production procedure.
Summary of the invention
The object of the present invention is to provide a kind of long service life and tunnel drying hole hot air flue ladder cover board type valve easy to adjust.
For achieving the above object, the present invention can take following technical proposals:
Tunnel drying of the present invention hole hot air flue ladder cover board type valve, comprise the adjusting flashboard that is arranged on the hot air flue import and export, the stairstepping pedestal of described adjusting flashboard for building by laying bricks or stones with refractory brick along the hot air flue two side, and be horizontally set on screen between two pedestals along each ladder platform of described pedestal successively, on described screen, be placed with sideboard; Be placed on along the ladder platform and formed inclined grate when sideboard on each screen tilt to be placed.
Described pedestal is 4～5 stepladderses, and the height of every stepladders is the width of 1/ 2 screens.
Described sideboard is a plate shape refractory brick, and its middle part horizontal symmetrical offers two and adjusts blind hole.
Between the pedestal of the both sides, top of hot air flue, built the refractory brick platform by laying bricks or stones.
The invention has the advantages that the service life that can prolong hot air flue import department valve, if there are indivedual sideboards to occur damaging in using, influence adjustment, can change the sideboard of damage separately, reduced the waste of steel, guarantee that whole operation production procedure carries out smoothly, improved production efficiency, guaranteed product quality.

Fig. 3 is the enlarged drawing of Figure 1A portion.
Fig. 4 is the structural representation of plate shape refractory brick among the present invention.
The specific embodiment
As Fig. 1,2,3, shown in 4, tunnel drying of the present invention hole hot air flue ladder cover board type valve, comprise the adjusting flashboard that is arranged on hot air flue 1 import and export, 4～5 steps trapezoidal pedestal 2 of described adjusting flashboard for building by laying bricks or stones with refractory brick along hot air flue 1 two side, and be horizontally set on screen 3 between two pedestals 2 along each ladder platform of described pedestal 2 successively, for guaranteeing the firm stable of screen 3, the height of every stepladders is the width of 1/ 2 screens 3, high temperature resistant for guaranteeing screen 3, indeformable, screen 3 can use plate shape refractory brick (460 * 230 * 65); On described screen 3, be placed with sideboard 4; Be placed on along the ladder platform and formed inclined grate when sideboard 4 on each screen 3 tilts to place.When every sideboard 4 is upright, just form a bar shaped grate mouth, hot flue gas can enter in the dry hole by this grate mouth, can make several sideboards 4 upright during real work as required, promptly open several grate mouths, to satisfy temperature requirement in the hole, when all sideboards 4 are obliquely installed simultaneously, just form the inclined grate of a sealing, hot flue gas can be blocked in outside the hole.
If sideboard 4 usefulness steel plates are made, because it is in the hot fume high-temperature environment for a long time,, when influencing adjustment, can change the sideboard of damage separately when deformed damaged appears in certain piece sideboard 4, reduced the waste of steel; When sideboard 4 adopts plate shape refractory brick, not only to draw materials conveniently, be convenient to change, cost is low, owing to can not produce high temperature deformation, can also improve its service life, reduces the influence to whole operation, has improved operating efficiency; Offer two in plate shape refractory brick middle part horizontal symmetrical and adjust blind hole 5, when needing to adjust temperature, use specific purpose tool to insert and adjust in the blind hole 5 and can carry out the adjustment of upright or obliquity plate shape refractory brick.
Built refractory brick platform 6 by laying bricks or stones between the both sides pedestal at hot air flue 1 top, the height of its refractory brick platform can be controlled hot flue gas and enter in the hole from the flue bottom about 300mm, improves the utilization rate of hot flue gas.
