Abstract
The utility model discloses an air valve reversing device of a metal heat treatment industrial furnace. The air valve reversing device comprises two air valve reversing device bodies, wherein the two air valve reversing device bodies are installed in air channels in the two sides of a fan respectively and parallel to an axis of the fan. Each air valve reversing device body is connected with valve plate assemblies through connecting plates by an air cylinder, and the two ends of each valve plate assembly are fixed through a mounted bearing and a shaft sleeve respectively to ensure that the valve plate assembly rotates flexibly. Two to six valve plate assemblies can be selected in each air valve reversing device body according to the width of the corresponding air channel, and the connecting plates are driven to stretch or retract by piston rods of the air cylinders, so that the valve plate assemblies rotate around the bearings and the shaft sleeves at the two ends, and the rotation angle is 90 degrees.
Description
Technical field:
The utility model belongs to metal heat treatmet industrial furnace corollary equipment technical field, and what be specifically related to is metal heat treatmet industrial furnace air-valve reversing arrangement.
Background technology:
In metal material heat treatment industry, industrial furnace is necessary equipment, be mainly used in to metal material heat, the heat treatment work such as timeliness, annealing.During work, require metal material quick heating, temperature even; By adopting air-valve reversing arrangement, hot air circulation direction is changed, the two ends of metal material are heated simultaneously like this, guarantee being rapidly heated of material, can also save the energy, have dwindled the temperature difference at material two ends, have also met the uniformity of temperature.Reached desired mechanical performance after metal material heat treatment.
The heat treatment mode of metal current heat treatment industrial furnace has two kinds of structures: a kind of is that hot blast remains a direction circulation, by long-time intensification at a slow speed, reach the uniformity of metal material two ends temperature, this mode programming rate is slow, and efficiency is low, poor temperature uniformity, waste energy; Another kind of mode is the structure that adopts reversible fan, by changing the direction of rotation of reversible fan, the loop direction of hot blast is changed, meet the intensification requirement of metal material, this by the mode of the frequent commutation of reversible fan, the life-span of blower fan can shorten greatly in actual applications, and maintenance is frequent, maintenance cost increases, and affects production efficiency.
Summary of the invention:
The purpose of this utility model is to overcome existing above-mentioned deficiency in existing metal heat treatment equipment, provide a kind of can be frequently, metal heat treatmet industrial furnace air-valve reversing arrangement fast.
The technical scheme that realizes above-mentioned purpose is: a kind of metal heat treatmet industrial furnace air-valve reversing arrangement, two groups of air-valve reversing arrangements are installed respectively in the air channel, both sides of blower fan, two groups of air-valve reversing arrangement installations parallel with fan shaft; Every group of air-valve reversing arrangement is connected with valve board assembly by connecting plate by a cylinder, valve board assembly two ends are fixed with rolling bearing units and axle sleeve respectively, guarantee that valve board assembly rotates flexibly, in every group of air-valve reversing arrangement, the quantity of valve board assembly can be selected 2～6 according to the width in air channel, by cylinder piston rod, drive connecting plate to do stretching motion, valve board assembly is rotated, the anglec of rotation 90 degree around bearing and the axle sleeve at two ends.
The utility model has the advantage of: stove is in running, and air-valve reversing arrangement, according to the requirement of Technology for Heating Processing, carries out the commutation of different frequency, and stable action, reliable.
