Description

Glass melting furnace mixture feeding device Technical Field The utility model belongs to the technical field of glass melting furnaces, and particularly relates to a glass melting furnace mixture feeding device. Background Before the glass melting furnace is produced, the melting furnace temperature is gradually increased to about 1600 ℃, raw materials required by glass production, such as silicon dioxide (SiO 2, commonly called silica sand), sodium oxide (Na 2 O), calcium oxide (CaO) and sodium silicate Na 2SiO3) and the like, are added, broken glass is required to be added in the early stage, before the melting furnace is heated to 1600 ℃, a burning gun is arranged at the position of a charging port, a inclined blanket type charging machine cannot perform normal charging, and raw materials (mixture, usually powder material and broken glass) required by glass production are required to be added by the charging machine. The feeder works on the principle that the glass raw material in the bin is blown into the melting furnace by utilizing wind generated by the high-pressure fan. The defects of the prior art are that 1, the lower part of the storage bin is a square body with large upper part and small lower part, for example, when the humidity of the material is high and broken glass is clamped in the raw materials, the square body easily forms dead angles at four corners, so that the blanking is difficult, 2, the push-pull type horizontal flashboard arranged at the lower part of the storage bin is very difficult to push and pull due to the obstruction of glass raw materials, so that the blanking flow of the glass raw materials is difficult to control. And 3, the glass raw materials are continuously piled up in the feeding process of the feeder, the air outlet is blocked, feeding cannot be performed, the feeder is required to be welded and adjusted and lifted for many times, and the feeder is required to be worn and operated by a thick heat-insulating working clothes due to high temperature during field operation, so that the high-temperature environment is bad, and the operation difficulty is high. The prior art is named as a method and a special feeding device for hot charging of a glass melting furnace, and the technology with the publication number of CN1847173A relates to the method and the special feeding device for hot charging of the glass melting furnace. The method comprises the steps of raising kiln temperature, installing a special feeding device, connecting a gas compressor with the tail end of a horizontal material pipe through a pressure measuring executing device, and controlling the compressor to intermittently exhaust gas into the horizontal material pipe by the pressure measuring executing device according to the lifting change condition of air pressure at the air outlet of the compressor until glass clinker meeting the conventional requirement of hot kiln loading in weight is fed into a melting furnace. The special feeding device has the structure that the lower part of a vertical material pipe with the upper end and the lower end being open is communicated with the middle section of a horizontal material pipe with the head end and the tail end being open, the upper side of the head end of the horizontal material pipe is provided with a forward extending blocking piece, and an air outlet end is arranged outside the horizontal material pipe and penetrates into a cooling air pipe in the head part of the horizontal material pipe. The method ensures that the amount of cold air entering the melting furnace is less, so that the disturbed degree of the temperature system in the furnace is effectively reduced, the oil consumption is reduced, the furnace structure is protected, and the grid body is kept smooth. The special feeding device has lower cost. However, this technique does not relate to the technical problem and technical solution of the present application. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides the glass melting furnace mixture feeding device which has a simple structure, can ensure smooth feeding of the mixture, can conveniently clear blockage of a feeding air pipe and meets the field use requirement.
