Embodiment Construction
[0028] A kind of embodiment 1 of gypsum calciner, in Figure 1 to Figure 5 Among them, including the furnace body 1, the furnace body 1 is cylindrical, and its inner surface and outer surface are both cylindrical surfaces, and the upper and lower end plates 2 are sealed on the upper and lower openings of the side wall of the furnace body 1, so that the furnace Body 1 has a square cavity. There is a gas distribution plate 3 in the lower part of the inner cavity of the furnace body 1, and the edge of the gas distribution plate extends to the inner wall of the furnace body 1 and is fixed on the inner surface of the gas distribution plate, so that the gas distribution plate 3 will cover the inner cavity of the furnace body 1. The lower part is separated to form an air inlet cavity 5, and the air inlet holes 4 are evenly distributed on the gas distribution plate 3, and the size of the air inlet holes 4 of the gas distribution plate 3 is 50 mesh. An air inlet 6 is provided on the f...

The invention discloses a gypsum calciner. The lower part of the furnace body is an air inlet chamber, and an air inlet connected with the air inlet chamber is provided on the furnace body. There is a calcining area on the furnace body. There is a rotating shaft between the center of the plate and the lower end plate, a slag discharge slot is opened on the gas distribution plate, a slag scraper and a baffle are arranged on the rotating shaft, a driving wheel is arranged on the rotating shaft, and inner gear teeth are arranged on the edge of the baffle , between the outer edge of the baffle and the driving wheel, there is an intermediate gear that meshes with the inner gear teeth, and a part of the driving wheel is protruded to cooperate with the intermediate gear. The active teeth of the slag joint, the gas distribution plate and the baffle are provided with a spring structure that resets the baffle to the position that blocks the slag discharge gap after the active teeth and the teeth of the intermediate gear are separated, and the gas distribution plate is set as a baffle positioning edge. The invention can prevent the accumulation from affecting the intake air and can discharge the slag into the intake cavity, thereby realizing continuous production.
Description
technical field [0001] The invention relates to a gypsum calciner, belonging to the technical field of gypsum processing devices. Background technique [0002] Under normal circumstances, desulfurized gypsum cannot be applied directly, and usually needs to be prepared into β-hemihydrate gypsum (CaSO4·0.5H2O, industrially known as plaster of paris). When dihydrate gypsum is heated to a certain temperature, it is easy to lose part of the crystal water and become plaster of paris. The calcination process has always been the main factor affecting the quality and application of desulfurized gypsum products. The main problems are divided into the following three types: firstly, impurity particles are easy to remain in the desulfurized gypsum, and the impurity particles will be deposited at the bottom of the calcination equipment, affecting the continuity of production; and, When these residual impurity particles accumulate to a certain extent, it needs to be shut down for treatme...
