DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0027] As Figures 1 - 3 shown, a horizontal high-temperature mixing granulation kettle includes a drive motor 1 and a horizontal cylinder 14, and a mixing assembly connected to the drive motor 1 is provided inside the horizontal cylinder 14; the mixing assembly is horizontally arranged inside the horizontal cylinder 14, a feed port 21 is formed at the top of the horizontal cylinder 14, and a discharge port 20 is formed at the bottom of the horizontal cylinder 14; the mixing assembly includes a horizontally arranged main shaft 10 and cross bars 15 equidistantly connected to the main shaft 10, the cross bars 15 are vertically arranged on the main shaft 10, and the cross bars 15 at the same length position of the main shaft 10 are located on the same straight line, and all the cross bars 15 are located on the same plane; first inner spiral band 5, second inner spiral band 13, first outer spiral band 18 and second outer spiral band 6 are provided on the cross bars 15, and head scrapers are provided between the cross bars 15 and the main shaft 10, and cylinder scrapers 16 are provided between adjacent cross bars 15; a breather of the main shaft 9 is formed on the main shaft 10.

[0028] The horizontal cylinder 14 includes a straight cylinder welded to elliptical heads at both ends of the straight cylinder. TIG welding is used for the root pass and submerged arc welding for the cover pass. The welds are inspected by radiography. A reasonable ratio of diameter to height is beneficial to mixing and granulation efficiency. Practical verification shows that a cylinder net height ratio of 0.8 - 1.2 is more appropriate. At 650 °C, the material is S30408 or 310S, and both require solution treatment to eliminate internal stress and extend service life. At the same time, the inner surface of the horizontal cylinder 14 is mirror polished to 0.25 - 0.45 μm. The top of the horizontal cylinder 14 is provided with a feed port 21, and the bottom is provided with a discharge port 20. The flange of the discharge port 20 is laser cut to form the same arc surface as the horizontal cylinder 14, so that the spiral ribbon will not be scratched. Flush-mounted temperature sensors 19 are provided at the bottoms of both heads, and the head scraper does not need to be cut with a notch, which has higher strength.

[0029] Because during the operation of the high-temperature autoclave equipment, the inner cylinder bears a positive pressure of 0.3 - 0.6 MPa. Operating the equipment under this condition, considering the strength, stiffness, and safety of the equipment operation, the steel plate material used for the equipment is the most economical, and it is convenient for manufacturing, transportation, inspection, and maintenance. By setting the cylinder net height ratio to 0.8 - 1.2 and reducing the ratio of the diameter to the length of the horizontal cylinder 14, the wall thickness of the horizontal cylinder 14 increases. If it exceeds the limit, heat treatment is required, increasing the cost. If the ratio of the diameter to the length of the horizontal cylinder 14 increases, the main shaft also needs to be lengthened and thickened, and many support parts will be added during manufacturing, which also increases the cost. The ratio of the pitch P to the cylinder diameter D is 0.35 - 0.5 to ensure fast mixing speed and high efficiency of the material in the cylinder: Usually, each batch of material mixing is fully mixed in 1 - 10 minutes, which is 6 - 10 times or higher more efficient than other mixers.

[0030] The main shaft 10 is a partially hollow shaft, made of S30408 or 310S, both of which are stress-relieved. Two or more main shaft breathing ports 9 are provided in the hollow part. The diameter of the main shaft breathing port 9 is Φ6 - Φ20 mm. During the air heating process, it is a process of increasing temperature and pressure, and the high-pressure gas inside must be discharged in time to form equal pressure between the shaft cavity and the inner cylinder. The main shaft breathing port 9 effectively solves the fatigue effect of the shaft, mainly to improve stiffness and reduce the fatigue effect and extend the service life.

[0031] The fixing method of the cross bar 15 to the main shaft 10 is as follows: First, drill through holes in the cross bar 15 and the main shaft 10 for welding, and then use the strengthening seat 17 with a conical cylinder structure to fix the cross bar 15 and the main shaft 10. The strengthening seat 17 is provided with a breathing port with a diameter of Φ5 - Φ12 mm, which effectively disperses the force on the cross bar 15 to the main shaft 10. Then the concentrated force on the cross bar 15 is effectively dispersed, effectively avoiding cracks and fractures at the connection between the main shaft and the cross bar.

[0032] On the main shaft 10, there are successively arranged a first crossbar group 15-1, a second crossbar group 15-2, a third crossbar group 15-3 and a fourth crossbar group 15-4. The first crossbar group 15-1, the second crossbar group 15-2, the third crossbar group 15-3 and the fourth crossbar group 15-4 are each composed of two crossbars 15 located on the same straight line.

[0033] The first inner spiral belt 5, the first outer spiral belt 18, the second inner spiral belt 13 and the second outer spiral belt 6 are all made of S30408 material, polished to 0.25 - 0.45 μm. By designing the corresponding relationship between the diameters of the inner and outer screw rods, the diameter of the outer spiral belt is equal to the diameter D of the horizontal cylinder 14 minus 30 mm, the ratio of the inner spiral belt to the outer spiral belt is 0.4 - 0.5, the width of the spiral belt is 140 - 160 mm, the thickness of the spiral belt is 14 - 20 mm, the ratio of the pitch P of the spiral belt to the cylinder diameter is 0.35 - 0.5, and the distance between the spiral belt and the horizontal cylinder 14 is 5 - 8 mm. The outer spiral belt pushes the material from the outside to the middle, and the inner spiral belt transports the material from the middle to the outside, forming a convection to improve the mixing effect.

[0034] Between the first crossbar group 15-1 and the second crossbar group 15-2, there is a connected first inner spiral belt 5, and the first inner spiral belt 5 is connected to the crossbar 15 arranged diagonally between the first crossbar group 15-1 and the second crossbar group 15-2. Between the third crossbar group 15-3 and the fourth crossbar group 15-4, there is also a connected first inner spiral belt 5, and the first inner spiral belt 5 is connected to the crossbar 15 arranged diagonally between the third crossbar group 15-3 and the fourth crossbar group 15-4. The two first inner spiral belts 5 are centrosymmetric about the center of the middle part of the main shaft 10. The first inner spiral belt 5 is of a corrugated structure. The end of the first inner spiral belt 5 is connected to the middle part of the crossbar 15 of the second crossbar group 15-2 or the fourth crossbar group 15-4, and the bent part of the first inner spiral belt 5 is connected to the middle part of the crossbar 15 of the first crossbar group 15 or the third crossbar group 15-3.

[0035] Between the first crossbar group 15-1 and the second crossbar group 15-2, there is a connected first outer spiral belt 18, and the first outer spiral belt 18 is connected to the crossbar 15 arranged diagonally between the first crossbar group 15-1 and the second crossbar group 15-2. Between the third crossbar group 15-3 and the fourth crossbar group 15-4, there is also a connected first outer spiral belt 18, and the first outer spiral belt 18 is connected to the crossbar 15 arranged diagonally between the third crossbar group 15-3 and the fourth crossbar group 15-4. The two first outer spiral belts 18 are arranged in parallel, and the first outer spiral belt 18 intersects with the first inner spiral belt 5.

[0036] Both the second crossbar group 15-2 and the third crossbar group 15-3 are provided with a second inner spiral band 13 and a second outer spiral band 6. Both the second inner spiral band 13 and the second outer spiral band 6 are arc-shaped structures, and the openings of the second inner spiral band 13 and the second outer spiral band 6 face the main shaft 10. The second inner spiral band 13 is connected to the middle of the crossbar 15 of the second crossbar group 15-2 or the third crossbar group 15-3, and the crossbar 15 is connected to the middle of the second inner spiral band 13. The second outer spiral band 6 is connected to the end of the crossbar 15 of the second crossbar group 15-2 or the third crossbar group 15-3, and the crossbar 15 is connected to the middle of the second outer spiral band 6. The second inner spiral band 13 and the second outer spiral band 6 are respectively connected to two crossbars 15 of the second crossbar group 15-2 or the third crossbar group 15-3, and the second inner spiral band 13 and the second outer spiral band 6 on the second crossbar group 15-2 and the third crossbar group 15-3 are centrosymmetric about the center of the main shaft 10.

[0037] The first inner spiral band 5, the first outer spiral band 18, the second inner spiral band 13 and the second outer spiral band 6 are all sheet structures, and there are two first inner spiral bands 5, two first outer spiral bands 18, two second inner spiral bands 13 and two second outer spiral bands 6 in the horizontal cylinder 14.

[0038] The two first inner spiral bands 5 are centrosymmetrically arranged, the two first outer spiral bands 18 are parallelly arranged, the two second inner spiral bands 13 are centrosymmetrically arranged, and the two second outer spiral bands 6 are centrosymmetrically arranged. The first inner spiral band 5 and the second inner spiral band 13 are used to stir the graphite in the middle of the horizontal cylinder 14, and the first outer spiral band 18 and the second outer spiral band 6 stir the graphite outside the horizontal cylinder 14. Since the first inner spiral band 5 and the first outer spiral band 18 are cross-arranged, the guiding directions of the first inner spiral band 5 and the first outer spiral band 18 for the graphite are opposite, realizing the convection between the graphite in the middle of the horizontal cylinder 14 and the graphite outside the horizontal cylinder 14, thus facilitating the mixing and stirring of the graphite. At the same time, the openings of the second inner spiral band 13 and the second outer spiral band 6 face in opposite directions, performing internal and external convection on the graphite at the same position in the same crossbar group position, thus facilitating the mixing and stirring of the graphite.

[0039] The head scraper includes a first head scraper 11 and a second head scraper 12 arranged parallel to the main shaft 10. The first head scraper 11 is connected between the first crossbar group 15-1 and the second crossbar group 15-2, and the second head scraper 12 is connected between the third crossbar group 15-3 and the fourth crossbar group 15-4.

The second cylinder scraper 16 is connected between the first crossbar group 15-1 and the main shaft 10, and the first cylinder scraper 8 is connected between the fourth crossbar group 15-4 and the main shaft 10.

[0040] The first cylindrical body scraper 8 and the second cylindrical body scraper 16 are used to increase the radial mixing intensity and improve the mixing and granulation efficiency. The first cylindrical body scraper 8 and the second cylindrical body scraper 16 are diagonally distributed. The distance between the scraper and the cylindrical body is 5 - 10 mm, and the angle between the cross bar and the main shaft is 0 - 10°. The gap between the walls of the horizontal cylindrical body 14 is made smaller, and the spiral ribbon is always running during discharging, so that the material moves towards the discharging valve and is basically all discharged.

[0041] The first head scraper 11 and the second head scraper 12 rotate 360° driven by the main shaft 10, scrape off the material sticking to the head in time and fully extrude and granulate. The angle between the scraper and the head surface is 0 - 5°, and the distance from the head is 4 - 6 mm.
