Description

Technical Field

[0001] This utility model relates to the field of shredder technology, and in particular to a crushing chamber structure for an oil sludge shredder. Background Technology

[0002] In the fields of industrial production and environmental protection, the efficient treatment and resource utilization of oily sludge, a complex mixture containing large amounts of grease, water, and solid particles, has always been an important issue in the industry. Improper treatment of oily sludge can not only cause serious environmental pollution but also waste recyclable resources. Therefore, the need for volume reduction, harm reduction, and resource utilization of oily sludge is becoming increasingly urgent. Currently, the treatment of oil sludge typically requires pre-treatment through crushing to break up the agglomerated structure and create favorable conditions for subsequent processes such as separation, dehydration, and pyrolysis. As a key piece of equipment in oil sludge crushing, the structure of the crushing chamber of the shredder directly affects the crushing efficiency, crushing effect, and the smoothness of subsequent processing. However, existing sludge shredders have several problems in practical applications. Firstly, the feeding structure of traditional shredders often lacks an effective guiding device, causing sludge to accumulate in the middle of the crushing chamber, resulting in uneven force on the shredding rollers. This not only affects crushing efficiency but also shortens the equipment's lifespan. Secondly, existing crushing chambers typically only have one set of shredding rollers. For viscous and complex sludge, thorough crushing is difficult, often requiring multiple crushing operations to achieve the desired effect, increasing processing time and energy consumption. Meanwhile, during the crushing process, the existing crushing chamber lacks an effective screening and separation structure. After crushing, the fine particles and larger particles in the sludge cannot be separated in time. The fine particles easily clog subsequent equipment, affecting the continuity of the entire processing flow. Moreover, some of the liquid generated during the crushing process cannot be discharged in time, causing the sludge to remain in the crushing chamber, further reducing the crushing efficiency. Therefore, this utility model proposes a novel solution. Utility Model Content

[0024] Please see Figure 1-8 This utility model provides a technical solution: a crushing chamber structure for an oil sludge shredder. The equipment assembly consists of a shredder upper shell 1 and a shredder middle shell 2, and a shredder middle shell 2 and a shredder lower shell 3, which are fixed by bolts to form a three-stage chamber structure. In the primary crushing assembly, a fixed blade 9 is welded to the inner wall of the shredder middle shell 2, and a first moving blade shaft 10 is connected to the shredder upper shell 1 and the shredder middle shell 2 via bearings. In the secondary crushing assembly, a second moving blade shaft 18 is installed between the shredder middle shell 2 and the shredder lower shell 3 via bearings, and gears 19 mesh to achieve reverse transmission.

[0025] Feeding process: Oil sludge enters from the feed hopper 4, the first drive motor 5 drives the first rotating shaft 6 to rotate, and the first spiral blades 7 on the surface push the oil sludge evenly to the primary crushing area between the upper shell 1 and the middle shell 2 of the shredder, so as to avoid the accumulation of oil sludge.

[0026] Crushing process: During operation, the first nozzle 22, the second nozzle 25, and the third nozzle 27 are suspended and sealed with sealing bolts 24 at the threaded holes of the shredder upper shell 1 to seal the top. The second drive motor 8 drives the first moving blade shaft 10 to rotate, and the first moving blade 12 rotates with it, cooperating with the first fixed blade 15 and the second fixed blade 16 on the fixed blade plate 9 to perform primary crushing of the oil sludge. The liquid produced by crushing is discharged through the filter holes 14 on the arc surface of the fixed blade plate 9, and the solid oil sludge falls into the secondary crushing area through the through groove 13. The third drive motor 17 drives the second moving blade shaft 18 to rotate, and the two second moving blade shafts 18 rotate in opposite directions through the meshing of gear 19. The second moving blade 20 cooperates with the third fixed blade 21 to perform secondary crushing of the oil sludge, and the crushed oil sludge is discharged from the discharge pipe 29.

[0027] Cleaning process: After crushing, remove the sealing bolt 24 and connect the first nozzle 22, the second nozzle 25 and the third nozzle 27 to the external water pump; the first nozzle 23 sprays water into the feed hopper 4 to rinse the residual oil sludge; the second nozzle 26 extends into the shredder upper shell 1 through the threaded hole to rinse the primary crushing area; the third nozzle 28 sprays water into the shredder middle shell 2 to rinse the fixed blade 9 and the surrounding area, and the rinsing wastewater is discharged from the discharge pipe 29 through the oil sludge crushing channel.

[0028] Example 1: When processing oily sludge with high oil content, in the primary crushing stage, the first moving blade 12 works in conjunction with the first fixed blade 15 and the second fixed blade 16 to tear apart the agglomerated structure of the oily sludge, and the filter holes 14 promptly filter out a large amount of oily liquid; in the secondary crushing stage, the staggered second moving blade 20 and the third fixed blade 21 crush the oily sludge to a particle size ≤5mm, which meets the pretreatment requirements for subsequent oily sludge separation.

[0029] Example 2: After crushing is completed, the flushing system is activated. The first nozzle 23 flushes the residual oil sludge in the feed hopper 4, the second nozzle 26 flushes the first moving blade 12 and the inner wall of the upper shell, and the third nozzle 28 flushes the surface of the fixed blade plate 9 and the second fixed blade 16. After flushing, the amount of residual oil sludge in each area is ≤1%, ensuring that the next crushing is not contaminated.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
