Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to an energy-saving crusher. Background Art

[0002] In clothing, shoes, hats, bags and other manufacturing companies, industrial solid waste such as scraps of processed products can be effectively utilized because they do not contain metal components. In order to improve the combustion efficiency of these industrial solid wastes, ensure their full combustion, and reduce the emission of harmful substances in the waste, a crusher is needed to crush these solid waste materials to an appropriate particle size. Most of the current crushers use conveyor belts to transport materials to the silo above the main machine, and they fall freely from top to bottom. There is a push plate inside the silo, which repeats a reciprocating motion. When the push plate pushes the material forward into the main shaft, it is forced to be crushed. The push plate moves backward to make the material above the push plate fall to the bottom and then pushes forward to continue to push the main shaft to crush. However, industrial solid waste such as clothing, shoes and hat boxes, due to its low density, will enter the crusher in a fluffy state. Fluffy waste is easy to block the feed port of the crusher, and fluffy waste is difficult to be crushed by the crushing components in the crusher. Since materials have different densities, existing crushers cannot provide a stable feeding environment for the crusher according to the different densities of materials, which seriously affects the crushing efficiency and the stability of the production process.

[0003] The fixed blade and the moving blade are also the core components of the crusher. There is a gap between the moving blade and the adjacent moving blade on the cutter roller of the crusher, and there is a gap between the fixed blades. The cutter roller needs to crush the waste for a longer time and repeatedly to fully crush the waste into small particles that meet the requirements, which will reduce the crushing efficiency of the crusher and increase the production cost.

When the accumulated waste passes between the roller 3 and the chain plate, the multiple material leveling plates 4 on the roller 3 rotate counterclockwise with the roller 3 (the counterclockwise rotation of the roller 3 is Figure 1In the main viewing angle in the figure, the multiple material leveling plates 4 continuously move the irregular and uneven thickness materials during the rotation process, so that they are spread on the chain plate and enter the feed port of the crusher body 1, thereby realizing the stable supply of materials; the roller body 5 is driven by the driving member to rotate counterclockwise (the counterclockwise rotation of the roller body 5 is Figure 1 The main viewing angle in the figure shows that when the waste transported by the chain plate passes between the roller body 5 and the mounting base 40, it can be compacted by the roller body 5, and both sides of the carrier where the roller body 5 is located are hinged to the crusher body 1 through the hydraulic cylinder 8. The two hydraulic cylinders 8 are connected to the hydraulic station 29. The rated working pressure of the hydraulic station 29 is 11Mpa. When the density of the waste is large and it is crushed by the roller body 5, a large pressure will be generated on the roller body 5. At this time, the rated output pressure of the hydraulic station 29 needs to be maintained. At this time, the accumulator in the hydraulic station 29 will release hydraulic energy to drive the hydraulic cylinder 8 to move upward until the difference between the upward lifting pressure of the hydraulic cylinder 8 on the carrier and the top pressure of the waste on the roller body 5 is equal to the rated working pressure of the hydraulic station 29, and the hydraulic cylinder 8 will stop moving upward; for waste with a lower density, when passing through the lower side of the roller body 5, the pressure applied to the roller body 5 by the waste during the compression of the roller body 5 is relatively small, and at this time, the piston end of the hydraulic cylinder 8 will drop, and the roller body 5 will move downward. Similarly, when the difference between the upward lifting pressure of the hydraulic cylinder 8 on the carrier and the top pressure of the waste on the roller body 5 is equal to the rated working pressure of the hydraulic station 29, the hydraulic cylinder 8 will stop moving downward. The above-mentioned leveling treatment of the waste by the material leveler and the compaction treatment of the waste by the roller body 5 are all for providing a stable feeding environment for the crusher body 1, avoiding the waste from being blocked in the crusher body 1, or causing the crusher body 1 to be stuck, and improving the crushing efficiency of the waste;

[0059] The knife roller 12 driven by the driving device on the crusher body 1 rotates counterclockwise (the counterclockwise rotation of the knife roller 12 is Figure 1The main viewing angle in the figure), after the waste is compacted by the roller body 5, when it passes between the fixed knife member and the knife roller 12, since the upper knife heads 11 on the fixed knife member are close to each other without gaps, and multiple rows of moving knife groups 1 2a are arranged at intervals along the length direction of the knife roller 12; between each two adjacent rows of moving knife groups 1 2a, a row of moving knife groups 2 2b and a row of moving knife groups 3 2c are arranged in sequence along the length direction of the knife roller 12, and between two adjacent upper knife heads 11 on the fixed knife member is a cutting channel, and each row of moving knife groups 1 2a, moving knife groups 2 2b and moving knife groups 3 2c are matched with a cutting channel. According to the arrangement and combination method of the utility model, more The cutting position is increased; the counterclockwise rotating knife roller 12 drives multiple moving knife pieces to rotate, and when the cutting body of any moving knife piece passes through the corresponding cutting channel, it contacts and cooperates with the upper knife heads 11 on both sides of the corresponding cutting channel, and can cut and crush the waste entering the cutting channel. Under the condition of the same knife roller 12 diameter and length, the use of the utility model can further improve the cutting efficiency, and make full use of the gap between each two adjacent rows of moving knife groups 2a to set the moving knife piece, so as to avoid the situation that the cutting gap is generated due to the spacing between the two adjacent rows of moving knife groups 2a, causing the waste to be trapped in the cutting gap and unable to be crushed;

[0060] Moreover, since the upper cutter head 11 and the lower cutter head 10 are detachably connected, when the cutting edge of the upper cutter head 11 is worn after long-term work, it is only necessary to release the connection between the upper cutter head 11 and the lower cutter head 10, and then reverse the upper cutter head 11 so that the original bottom surface becomes the top surface, and the top surface becomes the bottom surface. After the adjustment is completed, the upper cutter head 11 is reconnected with the lower cutter head 10 and can continue to be used; any movable knife body 35 and the corresponding fixed seat 34 are detachably connected. When the cutting body on any movable knife body 35 is worn, When adjustment is needed, the connection between the movable knife body 35 and the fixed seat 34 is released, the movable knife body 35 is rotated 90° with the central axis of its own threaded hole as the rotation axis, and then the movable knife body 35 and the fixed seat 34 are reconnected. At this time, the part of the movable knife body 35 extending out of the V-shaped groove 33 forms a new cutting body. When the movable knife body 35 rotates with the knife roller 12, the waste is cut and crushed. Therefore, the movable knife body 35 of the utility model can be used four times instead of twice, and the maintenance cost is reduced by half, which significantly reduces the cost.

[0061] After the waste is crushed, it falls into the silo and is discharged through the outlet.

Without violating the spirit of the present invention, i.e., the disclosure scope, any equivalent or equivalent deformation or replacement of the technical solution of the present invention shall fall within the protection scope of the present invention.
