Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dehydrator equipment, and more specifically to a compound dehydrator for gypsum used for removing external water and crystal water from industrial by-product gypsum. Background Art
[0002] Gypsum is a widely used industrial material and building material. It can be used as cement retarder, gypsum building products, model making, medical food additives, sulfuric acid production, paper filler, paint filler, etc. The microporous structure and heating dehydration of gypsum and its products make them have excellent sound insulation, heat insulation and fire resistance. Gypsum needs to be dehydrated during the processing process. At present, the industrial dehydrators on the market include press plate filter dehydrators, tripod pendulum dehydrators and belt dehydrators.
[0003] Among them, the platen filter dewatering machine is mainly used for sludge dewatering, which is mainly used to remove the external water with a water content of 15-30% in the sludge. Although the platen filter dewatering machine has a good effect, it is not suitable for the production and processing of industrial by-product gypsum, because the particle size range of gypsum is wide, ranging from micron level to millimeter level, and the surface of gypsum particles is smooth, not easy to be compressed, and even more difficult to pass through the small holes on the filter plate to achieve separation, resulting in high maintenance costs in the later stage;
[0004] Although the three-legged pendulum dehydrator can be used for gypsum dehydration, it generates centrifugal force through the high-speed rotating rotor to separate the water from the gypsum particles. In this process, the strong vibration and centrifugal force of the rotor will cause turbulence in the surrounding air, resulting in particularly loud noise. In addition, its mechanical structure is relatively complex, and the equipment cost and subsequent maintenance cost are high.
[0005] Belt dehydrators can be used to dehydrate gypsum. The working process is to discharge the gypsum slurry onto a conveyor belt with fine holes, and use vacuum suction to suck the conveyor belt to extract the moisture in the gypsum slurry, so that the gypsum blocks retained on the conveyor belt contain only a small amount of moisture, and most of the gypsum is peeled off the conveyor belt. During the process, the conveyor belt is prone to deviation, which will lead to wear between the various parts of the belt dehydrator, causing frequent malfunctions of the belt dehydrator and bringing safety hazards. In addition, the equipment is expensive and occupies a large area.
[0006] Therefore, how to provide a compound dehydration equipment for gypsum with a simple structure, easy use, reduced equipment cost and production noise is a problem that technical personnel in this field urgently need to solve. Utility Model Content
