Description

Technical Field

[0001] The invention relates to the technical field of sludge pyrolysis treatment, in particular to a municipal sludge regeneration resource treatment device. Background Art

[0002] Heating the sludge can decompose some organic matter and hydrolyze hydrophilic organic colloids, while decomposing and destroying microorganisms in the sludge, freeing water in the cell membrane, thus improving the concentration and dehydration performance of the sludge. Heat treatment is particularly effective for activated sludge with poor dehydration performance. Thermochemical treatment of sludge has the advantages of rapid treatment, small footprint, harmlessness, reduction and obvious resource utilization. By heating, the organic matter in the sludge undergoes chemical reactions, oxidizes toxic and harmful pollutants, kills pathogenic bacteria and other microorganisms, and destroys the cell structure by heating, so that the internal water in the sludge is released and removed. By closed heating, the sludge is heated in an anaerobic environment, thereby retaining the combustion value in the sludge to a large extent, and facilitating the recycling of the sludge. In order to achieve closed heating, the existing horizontal continuous sludge heating treatment device mostly adopts external heating, combined with internal stirring to achieve sludge heating, and the heating efficiency is not high.

[0021] 2. Through the setting of the adjusting mechanism, the driving rod can move forward and backward along its own axial direction when it rotates. When the driving rod moves forward, the convex block squeezes the limiting groove, thereby driving the stirring blade to rotate around the limiting rod, so that the inclination angle of the stirring blade increases, thereby increasing the gap between the contact part and the inner wall of the outer sleeve, thereby causing the contact part to separate from the inner wall of the outer sleeve. When the driving rod moves backward, the convex block relaxes the squeezing of the adjacent convex block, so that the stirring blade rotates under the resistance of the material. When the stirring blade rotates, the contact part fits with the inner wall of the outer sleeve, thereby cleaning the sludge crusted on the inner wall of the outer sleeve. When the stirring blade revolves, the stirring blade reciprocates to achieve intermittent cleaning of the inner wall of the outer sleeve, reducing the friction between the stirring blade and the inner wall of the outer sleeve, while achieving the cleaning of the sludge crusted on the inner wall of the outer sleeve, thereby facilitating the heating of the material.

[0034] Embodiment 1

[0035] like Figures 3 to 6As shown, in this embodiment, the outer wall of the central roller rod 210 corresponding to the position of the stirring blade 220 is fixedly connected with a vent pipe 211, the inner side of the stirring blade 220 is provided with an air passage 221, the bottom end of the stirring blade 220 is fixedly connected with two docking holes 222, the two docking holes 222 are located on the opposite sides of the stirring blade 220, the docking holes 222 are fixedly connected with the air passage 221, the bottom end of the stirring blade 220 is rotatably connected with a mounting seat 223, the mounting seat 223 is used to be fixedly connected with the central roller rod 210 by bolts, the vent pipe 211 is slidably connected with the inner wall of the adjacent docking hole 222, one end of the central roller rod 210 is rotatably connected with an annular seat 213, the other end of the central roller rod 210 is rotatably connected with an annular seat 1 212, the annular seat 1 212 and The annular seats 213 are all connected to the inner wall of the central roller rod 210, and the outer wall of the driving module 240 is equidistantly fixed with a partition plate 242. There is a one-to-one correspondence between the multiple driving modules 240 and the multiple stirring blades 220. The driving module 240 is used to separate the two ventilation pipes 211 in adjacent positions. The bottom end of the mounting seat 223 is fixedly connected with a limiting rod 224, and the outer wall of the limiting rod 224 is provided with a limiting groove 225. Three groove rods 243 are fixedly connected between the multiple partition plates 242. The groove rod 243 is slidably connected to the limiting rod 224, and a plurality of protrusions 244 are equidistantly fixed to the inner wall of one side of the groove rod 243. A venting portion 227 is provided in the middle position of the end of the stirring blade 220, and contact portions 226 are provided on both sides of the end of the stirring blade 220.

[0036] In the present embodiment, the annular seat 1 212 and the annular seat 213 are both connected to an external air heating device, so that hot air is introduced into the central roller 210, and the two adjacent ventilation pipes 211 are separated by the partition plate 242, so that the air passages 221 in the plurality of stirring blades 220 are in a series state, so that the hot air enters from one end of the central roller 210 and passes through the plurality of stirring blades 220 in sequence and is discharged from the other end of the central roller 210, so as to heat the stirring blades 220, so that when the stirring blades 220 rotate to move and stir the material, the stirring blades 220 further heat the material, thereby improving the heating efficiency and uniform heating degree of the material, and through the setting of the adjustment mechanism 300, the driving rod 241 moves forward and backward along its own axis direction when rotating, and when the driving rod 241 moves forward, the protrusion 244 squeezes the limiting groove 225, thereby driving The stirring blade 220 rotates around the limit rod 224, so that the inclination angle of the stirring blade 220 increases, thereby increasing the gap between the contact portion 226 and the inner wall of the outer sleeve 100, thereby causing the contact portion 226 to disengage from the inner wall of the outer sleeve 100. When the driving rod 241 moves backward, the protrusion 244 relaxes the squeezing of the adjacent protrusion 244, so that the stirring blade 220 rotates under the resistance of the material (because the material is pushed from front to back in the outer sleeve 100, the density and resistance of the material gradually increase from front to back, so that when the stirring blade 220 revolves, the resistance of the rear half of the stirring blade 220 is greater than the resistance of the front half, so that the stirring blade 220 rotates under the resistance of the material when the stirring blade 220 revolves). When the stirring blade 220 rotates, the contact portion 226 fits against the inner wall of the outer sleeve 100, thereby cleaning the sludge crusted on the inner wall of the outer sleeve 100. By causing the stirring blade 220 to reciprocate while revolving, the inner wall of the outer sleeve 100 is intermittently cleaned, and while reducing the friction between the stirring blade 220 and the inner wall of the outer sleeve 100, the sludge scab on the inner wall of the outer sleeve 100 is cleaned, thereby facilitating the heating of the material.

[0039] During specific implementation, the driving rod 241 rotates to drive the end plate 340 to rotate. Through the setting of the outer protrusion 331, the end plate 340 rotates relative to the track plate 330 while the end plate 340 moves forward and backward. When the end plate 340 revolves, it drives the round rod 342 to rotate. The round rod 342 drives the bevel gear ring 353 to rotate through the bevel gear 355. The bevel gear ring 353 drives the spur gear ring 354 to rotate through the rotating ring 352. The spur gear ring 354 drives the transmission gear 1 357 to rotate. The transmission gear 1 357 drives the transmission gear 2 358 to rotate through the shaft 356. The transmission gear 2 358 drives the sleeve 320 to rotate through the transmission gear 3 359, thereby driving the track plate 330 to rotate. When the driving rod 241 rotates, the track plate 330 is driven to rotate in the opposite direction, thereby changing the position of the outer protrusion 331, so that the stirring blade 220 rotates at different positions, thereby preventing the stirring blade 220 from repeatedly scraping the same position of the inner wall of the outer sleeve 100.
