Abstract
The utility model belongs to the technical field of vitrified micro bubble production, and relates to a heat exchange internal-external sleeve pipe for the feed and the discharge of a pitchstone vitrifying and expanding furnace, in particular to a feed and discharge delivery pipe of an energy-saving gas type vitrified micro bubble expanding furnace. The internal-external sleeve pipe comprises an internal pipe and an external pipe, and is characterized in that the internal pipe is positioned in the external pipe; fins are arranged on the outer wall of the internal pipe; and a nickel plated layer is arranged on the surface of the internal pipe and those of the fins. The utility model has the advantages that the fins are utilized to increase the heat absorption surface area of the internal pipe, so as to improve the heat exchange ratio of a raw material and a product in the internal-external sleeve pipe; the heat absorption quantity of pitchstone grit raw material in the expanding furnace is saved, so that the gas consumption is reduced; and the temperature of high-temperature expanded micro bubbles delivered from the external pipe is reduced, so that the cooling time in the air is reduced, the cost of high-temperature transmission equipment is reduced, environment pollution due to high temperature is reduced, and accidents are avoided.
Description
Technical field
The utility model belongs to the technical field of producing glass bead, particularly the input and output material carrier pipe of energy-saving gas formula glass bead puffing furnace.
Background technology
Can be puffed to glass bead with the pitchstone breeze under the high temperature about 1000 ℃, glass bead is widely used in the heat-insulating material with its extremely low proportion with the good affinity of cement.Chinese patent 200610112647 " manufacture craft of expanded microballon and revolve floating puffing furnace "; 200820076088 " the expanded electric furnaces of energy-saving glass bead "; 200820076086 " the expanded puffing furnaces of energy-saving gas formula glass bead "; 200620127293 " gas heating formula glass bead puffing furnaces " disclose the expanded puffing furnace of various microballons; but the expanded puffing furnace of these microballons all has its common shortcoming: the input and output material carrier pipe separates; can not carry out input and output material heat changes; the raw material that not only enters is many power consumptions in puffing process; and the high heat of discharging will be used the high temperature transmission equipment; the high temperature glass bead is cooled off in air; high temperature transmission equipment expense height; high temperature is contaminated environment also, may cause the accident.
Summary of the invention
The purpose of this utility model is the internal and external casing that provides the expanded microballon of high temperature of a kind of raw material that enters puffing furnace and output puffing furnace to carry out heat exchange for pitchstone vitreous puffing furnace.
Structure of the present utility model is:
The input and output material heat exchange internal and external casing of pitchstone vitreous puffing furnace, pipe and outer tube in comprising, it is characterized in that: interior pipe is positioned among the outer tube, and the outer wall of interior pipe is provided with fin.Interior pipe is used to carry pitchstone sand grains raw material, is used to carry the expanded microballon of high temperature shape and the high-temperature flue gas behind the fuel gas buring between interior pipe and the outer tube.The outer wall of interior pipe and fin are used to absorb the expanded microballon of high temperature shape and the heat energy of high-temperature flue gas, and heat energy passed to the pitchstone sand grains raw material of low-temperature condition, and the pitchstone sand grains raw material of low-temperature condition is carried out preheating, reduce the gas consumption that puffing furnace advances, save combustion gas, energy savings.
Fin on the interior pipe is connected with outer tube wall, makes the spacing distance between its interior pipe and the outer tube constant, and makes spacing distance constant without other supporter.
Interior pipe and fin are that metal is copper, and there is nickel coating on the surface of interior pipe and fin.Metal is copper to be the excellent material of heat conduction, but the corrosion resistant ability is relatively poor, so with pipe and fin in the nickel coating protection, reduce the damage of internal pipe of high-temperature flue gas and fin.
Fin is that the outer wall along interior pipe vertically is provided with.Making space trend between the fin is end to end from interior pipe, and promptly the expanded microballon of the trend of the space between the fin and high temperature shape and high-temperature flue gas moves towards identical.
Advantage of the present utility model: increased the heat absorption surface area of interior pipe with fin, improved the heat transfer rate of raw material and two kinds of materials of product in the internal and external casing.Save the caloric receptivity of pitchstone sand grains raw material in puffing furnace, saved gas consumption.Reduced the temperature of expanded microballon when the output outer tube of product high temperature shape, reduced cool time in air, reduced the high temperature transmission equipment and take, reduced high temperature, avoided causing the accident contaminated environment.
