Problems solved by technology
[0003]1. Uneven drying of materials caused by hot air resistance: after hot air enters from the inlet of the body, it must penetrate the entire material layer to the air outlet, and the wind pressure and temperature will continue to Decrease, so that the drying degree of the materials in each part is very different, and the result is "flower material", that is, some of the dried materials have been completely dried, and some are far from reaching the standard
At this time, it is not possible to blindly increase the temperature and pressure of the hot air to make all the materials qualified. This will not only waste energy, but may also cause spontaneous combustion accidents.
[0004]2. Insufficient dryness of corner materials: The material deposited on the inner wall of the machine body is the part that is least susceptible to hot air, and the hot air is often discharged from the shortcut air path, so The consequence of this is that in addition to easily forming flowers, it will also form blocking materials.
[0005]3. The phenomenon of debris caused by the self-weight of materials: Generally speaking, due to the consideration of economies of scale, the size of the dryer is relatively large, and there are many materials inside , then, the material at the bottom will bear the weight of the entire material and cause it to break. Take semi-coke as an example. The broken rate, such economic loss is staggering

Embodiment 1
[0021] In this embodiment, the body 1 is square, and an air inlet pipe 2 is inserted therein, and several air inlet pipes 2 are arranged horizontally on the same plane; The air inlet pipes 2 are also arranged horizontally on the same plane, and the air inlet pipe layer and the air receiving pipe layer are arranged at intervals and staggered in the vertical direction.
[0022] Both the air inlet pipe 2 and the lower part of the air receiving pipe 3 have a plurality of air outlets 4 .
[0023] When in use, the material falls from top to bottom until it fills the entire internal space. The external hot air enters the body 1 through the air inlet pipe 2 under the action of positive or negative pressure, and is discharged from the air outlet 4. Because the air inlet pipe 2 is uniform Distributed in the machine body 1, coupled with the arrangement of multiple air outlets 4, so multiple hot air can evenly dry all parts of the material in all directions.
[0024] At the same time, th...
Embodiment 2
[0030] In Example 1, there is an existing problem: the leftover material is close to the inner wall 6 of the machine body 1, the air path basically does not pass through here, and this part of the material still cannot be effectively dried by the hot air, resulting in "bloom" and The phenomenon that the stagnation cannot fall smoothly.
[0031] This embodiment effectively solves this problem: the fins 11 that are inclined downwards are fixedly connected around the inner wall 6, so that the material cannot stay on the inner wall 6.
[0032] Simultaneously, the outer wall 8 is set outside the inner wall 6 around, between the inner wall 6 and the outer wall 8 is an interlayer 7; under the wing plate 11, on the inner wall 6, there are ventilation holes 12, and the hot air is ventilated in the interlayer 7, and the hot air is just from the interlayer 7, the air vent. 12 enters the machine body 1, and directly dries the corner materials, and the hot air is still discharged from the ...
Embodiment 3
[0035] In this embodiment, in order to make the materials have a better rolling and transposition effect, a receiving plate 13 is arranged in the middle of the machine body 1 , and a pair of drums 14 are arranged under the receiving board 13 , and there are wing plates 15 on the drums 14 .
[0036] After the materials are dried to a certain degree, they are collected on the receiving plate 13 and fall onto the rotating drum 14. The rotating drum 14 has no power, and depends on the power of material blanking to move the wing plate 15 to rotate, and at the same time, the material also moves along with the wing plate. After 15 rotations and falling in batches, continue drying.
[0037] The purpose of the above process is to make the material mix more uniform, the drying degree more consistent, and the product index more stable.
[0038] In the figure, for the convenience of showing the internal structure, one panel is removed, but the equipment is actually closed.

Abstract
The invention relates to a vertical type material dryer. Blast pipes and air collecting pipes that pass through the dryer body are arranged in the dryer body; the blast pipes and the air collecting pipes are arranged in layers; herringbone beams are arranged at the upper ends of the blast pipes and the air collecting pipes; wind plates are arranged at the lower ends; air ports are formed on the wind plates; and the wall of the dryer body is a sandwich structure. The vertical type material dryer has the benefits that the hot air can be uniformly sent to the inside of the material, and the air can be collected at the nearest distance, as a plurality groups of drying units are arranged inside the material to ensure uniform heating on the whole material and avoid the nonuniform heating phenomenon of the material. At the same time, the blast pipes and the air collecting pipes, on the one hand, allow the material to move transversely during the dropping process and enable the material to be dried more uniformly, on the other hand, bear a part of weight of the material, greatly reduce the stress of the material at the lower end, and reduce the breakage rate of the material. The fin plates and the sandwich structure avoid that the material is retained at the wall, and the vertical type material dryer can dry the material in all directions without any dead angle.
Description
technical field [0001] The invention relates to a drying device. It is especially suitable for drying and drying of various granular materials (such as carbon materials, grain, etc.). Background technique [0002] The purpose of the dryer is to remove the excess moisture in the material. The common technology at this stage is to let in hot air to evaporate and take away the moisture in the material. The common technology is to set the air inlet and outlet on the body, and the hot air During the flow process in the body, the material in it is dried, and the material also has a feed port and a discharge port. Different drying equipments have different settings of air path and material path, but the drying devices at this stage all have the following technical defects: [0003] 1. Uneven drying of materials caused by hot air wind resistance: After the hot air enters from the inlet of the machine body, it must penetrate the entire material layer to the air outlet. The result...
