The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in figure 1, the waste plastic crushing device comprises a crushing box 1, a rotating shaft 2, a plurality of crushing cutters 3 and an air draft filtering component, the top and the bottom of the crushing box 1 are respectively provided with a feeding port 4 and a discharging filter plate 5 which is detachably arranged on the crushing box 1, two sides of the discharging filter plate 5 are respectively fixed with a connecting plate 14, each connecting plate 14 is detachably connected with the bottom of the crushing box 1 through a bolt 15, a plurality of supporting columns 16 for supporting the crushing box 1 are fixed at the bottom of the crushing box 1, the rotating shaft 2 is arranged in the crushing box 1 in a penetrating way and can rotate relative to the crushing box 1, the top of the crushing box 1 is fixed with a motor 17, the rotating shaft 2 is arranged at the output end of the motor 17, a plurality of crushing knives 3 are all fixed on the rotating shaft 2, the air draft filtering component is installed in the crushing box 1 and extends out of the crushing box 1 so as to be used for extracting the dust mixed gas in the crushing box 1 and filtering the dust and then discharging the dust. The air draft filtering component comprises a protective cover 6, an air draft fan blade 7, an air supply pipe 8 and a dust filter plate 9, wherein the air draft fan blade 7 is fixed on a rotating shaft 2, the protective cover 6 is fixed in a crushing box 1 and is covered outside the air draft fan blade 7, one end of the air supply pipe 8 is inserted into the protective cover 6, the other end of the air supply pipe is communicated with the dust filter plate 9 positioned outside the crushing box 1, the rotating action of the rotating shaft 2 is utilized in the mode, the rotating shaft 2 achieves the dual using action, the rotating shaft 2 can drive a crushing cutter 3 to rotate and cut waste plastic products, air draft can be driven to rotate the air draft fan blade 7, a large amount of processing cost can be saved from the manufacturing cost, and the working efficiency of the rotating shaft 2 is improved.

The filter box 10 with the discharge port is fixed outside the crushing box 1, the end part of the blast pipe 8 is communicated with the filter box 10, and the dust filter plate 9 is arranged in the filter box 10, so that the dust gas discharged from the blast pipe 8 is completely contained in the filter box 10, the bad phenomenon that part of the dust gas is directly discharged into the air from the end part of the blast pipe 8 is avoided, and the purpose of thorough dust removal is achieved. The dust filter 9 includes a filter screen 9a and a wet cloth 9b of dust absorption that adheres to on the filter screen 9a, and this dust filter 9 inserts to the rose box 10 in through a bar hole, and this kind of mode can be changed dust filter 9 to reach the purpose of long-term use.

The crushing box 1 is of a double-wall sandwich structure, the outer layer of the crushing box 1 is provided with a water inlet hole 11, the inner layer of the crushing box 1 is provided with a plurality of water spraying holes 12, cleaning water is introduced into the double-wall sandwich layer of the crushing box 1 through the water inlet hole 11, and the cleaning water is sprayed out of the water spraying holes 12 and sprayed onto plastic chips, so that the dust removal efficiency can be further improved. The crushing box 1 is of a cylindrical structure, the water spraying holes 12 are uniformly distributed in the inner layer of the crushing box 1, and the number of the water spraying holes 12 is increased, so that the cleaning efficiency of plastic fragments is further improved, and dust is better removed. The arrangement that the water spray holes 12 are all towards the center of the crushing box 1 enables water sprayed out of the water spray holes 12 to generate large scouring force on the plastic fragments, so that dust attached to the plastic fragments is scoured more thoroughly, and the plastic fragments are thoroughly cleaned.

The water spray holes 12 on the upper part of the crushing box 1 are all inclined downwards, the water spray holes 12 on the lower part of the crushing box 1 are all inclined upwards, in the actual processing, the number of waste plastic products thrown into the crushing box 1 is limited, the space occupied by waste plastic before crushing is large, after cutting processing, the space occupied by the formed small plastic fragments becomes small, therefore, the plastic fragments can be gathered at the middle part and the lower part of the crushing box 1, the water spray holes 12 on the upper part of the crushing box 1 are inclined downwards, the water spray holes 12 on the lower part of the crushing box 1 are all inclined upwards, the mode can fully spray water to wash the plastic fragments, and the dust removal efficiency is further improved.
