Description

Technical Field

[0001] The utility model relates to the technical field of drying machines, in particular to a novel double-drum drying machine. Background Art

[0002] Double-drum dryer is mainly used to dry granular materials within a certain humidity and particle size range, such as yellow sand used in dry mortar industry, various specifications of molding sand used in foundry industry, blast furnace slag used in building materials and cement industry, small-grained clay, and small-grained materials that cannot undergo chemical changes and are not afraid of being contaminated by high temperature and smoke in the chemical industry. The drum in the dryer rotates continuously during operation, and the materials are continuously lifted up in the drum. Hot air is introduced into the dryer, and the hot air is in full contact with the lifted materials to achieve the purpose of drying the materials.

[0003] The disadvantage of the double-drum dryer in the prior art is that during the feeding process, the material is wet and easily adheres to the flow channel below the feed port and adheres to the flow channel, which easily causes blockage during feeding.

[0004] The patent publication number CN201397016Y was retrieved. The patent name is a public material of a double-drum dryer used in the cement production process, and specifically discloses a double-drum dryer, which contains a composite cylinder, a feed pipe, a discharge device and a transmission device. The composite cylinder is composed of an outer cylinder and an inner cylinder concentrically mounted, and also contains a uniform air distribution device, which is composed of a cone, a porous tube and a porous plate. The left end of the porous tube is fixed on the small end of the cone, and the right end is connected to the porous plate. There is a gap between the inner side of the porous plate and the right end of the porous tube. The large end of the cone is arranged at the left end of the outer cylinder, and the porous tube is arranged in the inner cylinder through a bracket. Since the inner cylinder is provided with a uniform wind dispersing device, when the material is lifted by the spiral lifting plate, a material flow like a waterfall is formed in the process of falling. When the material flow encounters the porous tube of the uniform wind dispersing device, it collides with the surface, and the material flow is dispersed and diffused in the space between the inner cylinder and the porous tube. The high-temperature hot air flow ejected from the through holes of the porous tube fully exchanges heat with the dispersed material, thus overcoming the deficiency of the prior art that the material in the middle of the material flow cannot fully exchange heat with the high-temperature hot air, thereby improving the drying efficiency of the dryer. Since the high-temperature hot air ejects uniform high-temperature hot air through the through holes of the porous tube and diffuses in the space between the inner cylinder and the porous tube, it helps to evenly dry the material, thereby facilitating the improvement of the drying efficiency of the material.

[0005] By analyzing the above-mentioned public materials, it can be known that the double-drum dryer can achieve the drying of materials, but during use, it is easy to cause blockage when unloading materials. From the drawings and descriptions in the specification, it can be known that during the unloading process, the materials are easy to stick to the inner wall of the feed pipe. Utility Model Content
