Detailed Description
The present invention will be further described with reference to the following detailed description.
Referring to fig. 1 to 4, a gas-solid flow divider of a drying roller, which is arranged in the middle of the roller to separate materials from hot flue gas, comprises two connecting cylinder sections 1, a material feeding section 2 arranged between the two connecting cylinder sections 1, and an outer shell 3 wrapped outside the material feeding section 2.
The connecting cylinder section 1 is formed by a part of the cylinder body of the roller, the connecting cylinder section 1 rotates along with the cylinder body, and the connecting cylinder section 1 drives the feeding pipe section 2 to rotate together.
The material feeding section 2 comprises a plurality of material feeding pipes 21, each material feeding pipe 21 is close to the wall of the roller and arranged in an annular array mode around the axis of the roller, material passing holes 22 are formed in two ends of each material feeding pipe 21, an annular baffle 23 is arranged between each connecting cylinder section 1 and the material feeding section 2, the material passing holes 22 are formed in the annular baffle 23, the material passing holes 22 in the two ends of each material feeding pipe 21 are arranged on the two annular baffles 23 in a staggered mode, so that the material feeding pipes 21 are obliquely connected with the two connecting cylinder sections 1 relative to the axis of the roller, materials are conveyed to the other end connecting cylinder section 1 from one end connecting cylinder section 1 through the material feeding pipes 21, first exhaust holes 231 are formed in the middle of each annular baffle 23, and the material feeding pipes 21 are arranged at intervals to form second exhaust holes 211 enabling smoke to pass.
The length of shell body 3 is greater than 2 length of walking material section in order to wrap up in it completely walking material section 2, and shell body 3 is fixed to be set up, and both sides are connected through labyrinth sealing mechanism 31 between shell body 3 front and back and connecting cylinder section 1, but make shell body 3 and connecting cylinder section 1 relative rotation's airtight connection, and shell body 3 upper portion is equipped with gas outlet 32, and hot flue gas loops through first air exit 231, second air exit 211 and gets into in the shell body 3 and see off from gas outlet 32.
The utility model provides a drying roller, includes a drying roller gas-solid diverging device, and this kind of drying roller gas-solid diverging device selects the middle section position of locating drying roller according to the design demand.
The working principle of the drying roller and the gas-solid flow dividing device of the drying roller is as follows:
a drum drying method, the supplies are sent into the cylinder from one end of the cylinder, the supplies rotate with the cylinder and transport backwards, when the supplies reach the boundary of connecting cylinder section 1 and material feeding section 2, because of the block of the annular baffle 23, the supplies can't cross the annular baffle 23 and enter the material feeding section 2, the supplies will enter the material feeding pipe 21 from the material passing mouth 22 that the annular baffle 23 offers, the material feeding pipe 21 rotates with the cylinder, and the material feeding pipe 21 sets up obliquely relative to the axis of the cylinder, the feeding direction of the material feeding pipe that sets up obliquely can be changed by changing the direction of rotation of the cylinder, therefore can connect pipe section 1 and enter the material feeding pipe 21 to connect pipe section 1 of another end while the material feeding pipe 21 rotates, the supplies after passing the material feeding section 21 continue to transport backwards with the cylinder, namely the supplies pass the whole length route of cylinder; the hot flue gas forms and gets into in the cylinder from cylinder one end, when the hot flue gas reaches connecting cylinder section 1 and walks the boundary department of material section 2, gaseous state hot flue gas can not be blockked by ring baffle 23, and will get into in the material section 2 from the first exhaust opening 231 in ring baffle 23 middle part, then enter into shell body 3 through the second air exit 211 that forms between each punishment in pipe 21, finally leave the cylinder in advance through gas outlet 32, hot flue gas has one section to overlap in the route that passes through of cylinder and material at the cylinder, heat transfer is carried out with the material to the hot flue gas of this overlapping section department, in order to heat up the stoving to the material.
Therefore, by additionally arranging the gas-solid flow dividing device of the drying roller, the hot smoke can be discharged in advance, the inconsistent design of the path length of the materials passing through the roller and the path length of the hot smoke passing through the roller is realized, and the design of more flexible heat exchange and heat preservation time is realized, so that the device is used as basic equipment to provide more process design ideas.
The above-mentioned only be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and all utilize this design right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
