Chinese patent 200610112647 "Manufacturing process of puffed microbeads and its rotary-floating puffing furnace", 200820076088 "energy-saving vitrified microbead puffed electric furnace", 200820076086 "energy-saving gas-type vitrified microbead puffed puffing furnace", 200620127293 "gas heating Type Vitrified Microbead Puffing Furnace "discloses various microbead puffing puffing furnaces, but these micropuffing puffing furnaces all have its common shortcoming: (1) the expanded vitrified microspheres are directly released from below the puffing furnace, Since the specific gravity of the puffed vitrified microbeads is light, and the hot gas in the puffing furnace is upward, the descending and discharging speed of the puffed vitrified microbeads is affected by the upward resistance of the hot gas, so the puffing furnace must Use a very high height to meet the needs of high-temperature puffing and puffed vitrified microspheres slowly descending and discharging, resulting in a large amount of steel and insulation materials for the puffing furnace, and the equipment cost of the puffing furnace is very high
(2) The temperature of the puffed vitrified microbeads falling from the bottom of the puffing furnace is too high, and high temperature resistant equipment is required to accept the vitrified microbeads just out of the furnace, and the cost of high temperature equipment is high; (3) the high temperature glass just out of the furnace The high-temperature transmission equipment will be used to cool the high-temperature vitrified microbeads in the air, and the cost of high-temperature transmission equipment is high; (4) the high-temperature vitrified microbeads that have just been released from the furnace are cooled in the air to cause thermal pollution to the environment, making workers The working environment is harsh, and may even cause accidents of scalding people; (5) The expanded vitrified beads, unexpanded raw materials, sundries, etc. are mixed and output from the bottom of the extruding furnace, the product quality is poor, and the unexpanded raw materials are mixed and exported. waste
In short: the existing technology does not utilize the waste heat of the high-temperature vitrified microbeads just out of the furnace, and in order to solve the problem of waste heat, the equipment cost of the puffing furnace is greatly increased. The waste heat also pollutes the environment, and unexpanded raw materials can also be mixed into the puffed vitrified microbeads Medium, poor product quality

Abstract

The invention relates to pitchstone bulking equipment and a method for bulking production of vitrified micro bubbles, belonging to an energy-saving fuel gas type vitrified micro bubble bulking furnace and bulking process. The pitchstone bulking equipment comprises a charging hopper, a discharging hopper, an inner and outer sleeved double-layer pipe and an upper-end discharging and bulking furnace, wherein two ends of the inner pipe of the inner and outer sleeved double-layer pipe are respectively communicated with the charging hopper and the top end of the upper-end discharging and bulking furnace, and two ends of the outer pipe of the inner and outer sleeved double-layer pipe are respectively communicated with the top end of the upper-end discharging and bulking furnace and the discharging hopper. In the bulking process, the upward hot gas in the upper-end discharging and bulking furnace is used for carrying over the bulked vitrified micro bubbles from the top end of the upper-end discharging and bulking furnace to enter the inner and outer sleeved double-layer pipe to carry out heat exchange together with the bulked vitrified micro bubbles and the accompanied hot gas. The invention can reduce the heat energy when the bulked vitrified micro bubbles are output, reduce the high temperature resistant equipment at the output end and reduce the high temperature pollution. Thus, the equipment of the invention is energy-saving equipment, and the process of the invention is an energy-saving process.

Description

technical field [0001] The invention belongs to the technical field of producing vitrified microbeads, in particular to an energy-saving gas type vitrified microbead puffing furnace and puffing process. Background technique [0002] Turpentine rock powder can be expanded into vitrified microspheres at a high temperature of about 1000 ° C. Vitrified microspheres are widely used in building insulation materials because of their extremely low specific gravity and good affinity with cement. Chinese patent 200610112647 "Manufacturing process of puffed microbeads and its rotary-floating puffing furnace", 200820076088 "energy-saving vitrified microbead puffed electric furnace", 200820076086 "energy-saving gas-type vitrified microbead puffed puffing furnace", 200620127293 "gas heating Type Vitrified Microbead Puffing Furnace "discloses various microbead puffing puffing furnaces, but these micropuffing puffing furnaces all have its common shortcoming: (1) the expanded vitrified micro...
