[0002] The float glass production process generally includes processes such as raw material crushing, weighing, mixing, melting, molding and annealing. Feeding the prepared raw materials into the melting furnace is one of the important links. Since the raw materials are fed into the melting furnace under high temperature, it cannot be done manually. Currently, most of them are fed using feeding devices.

[0003] For example, the patent with application number CN202311239849.X discloses a large glass kiln, including a kiln, a furnace mouth at the lower front side of the kiln, a sealing device located at the furnace mouth at the front side of the kiln, a silo in front of the kiln, and a feeding device between the bottom of the silo and the furnace mouth, wherein the feeding device includes a base, a crankshaft structure at the front of the base, a supporting wheel structure at the rear of the base, a feeding shovel slidably arranged on the supporting wheel structure and obliquely arranged downward from front to rear, a lifting baffle that can move up and down, and a material layer adjustment structure above the feeding shovel that can be adjusted up and down, wherein the crankshaft structure can drive the feeding shovel to move forward and backward and it moves in coordination with the lifting baffle; The number of the feeding devices is N, and the N feeding devices are arranged side by side on the left and right. The base can be adjusted forward and backward, and the supporting wheel structure can be adjusted up and down; the feeding device also includes a feeding bin cooperating with the feeding shovel and M sub-bins arranged side by side on its top, and N*M sub-bins are arranged side by side on the bottom of the bin and are provided with valves; the feeding bin is arranged in the left and right directions, and a feeding shovel is provided below it, a lifting baffle is provided on the front side, and M material layer adjustment structures are adjacent to each other on the left and right sides of the rear side; a material layer adjustment structure is correspondingly arranged directly below each sub-bin, and the raw materials in the sub-bin pass downward through the feeding bin to the feeding shovel.

[0004] In the prior art, the raw materials are uniformly fed into the feeding pool at the furnace mouth through a feeding device. However, the slurry temperature in the feeding pool is very high, and the heat will be transferred to the feeding device, affecting the service life of the feeding device. In the prior art, a heat insulation structure can be set between the feeding pool and the feeding device, but the feeding pool is usually made of refractory bricks (usually customized, and the size, position and shape are all determined by the refractory brick manufacturer), and it is not easy to set a heat insulation structure.

The feeding pool 2 is made of refractory bricks, and notches 3 are provided at both ends of the left and right sides of the front side (it can be formed by installing one less refractory brick, or adjusted (small adjustment)), and a heat insulation layer 4 and a water-cooled plate 5 are provided on the front side from back to front. The function of the heat insulation layer 4 is heat insulation, which can specifically be a rock wool layer, a glass fiber layer or an asbestos layer. Specifically, the heat insulation layer 4 is an asbestos insulation layer with a thickness of 2-4 cm. Specifically, the notch 3 is a rectangular notch, which includes a left-right surface arranged along the left-right direction and a front-back surface arranged along the front-back direction, and the front-back surface is located at the front side of the inner end of the left-right surface. The water-cooled plate 5 is connected to the cold water circulation system (including the cooling tower) through a pipeline, and two clamping mechanisms 6 and two supporting mechanisms 7 are provided on its rear side.
