[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Please refer to Figures 1-5 The present application provides a technical scheme: a papermaking waste residue chopping and drying pretreatment device, comprising a pretreatment mechanism 1 and a chopping mechanism 2 assembled on one side of the pretreatment mechanism 1, the pretreatment mechanism 1 comprising a crushing box 101 and a drying box 3, two groups of crushing wheels 102 being rotatably installed inside the crushing box 101, two groups of crushing motors 103 being fixedly installed on one side of the crushing box 101, a cloth box 105 being fixedly installed at the bottom of the crushing box 101, a cloth wheel 107 being rotatably installed inside the cloth box 105, a cloth motor 106 being fixedly installed on the front of the cloth box 105, a conveying belt 5 being rotatably installed inside the drying box 3, a conveying motor 503 being fixedly installed on one side of the front of the drying box 3, heating rods 301 being fixedly installed at equal distances above the inside of the drying box 3, the chopping mechanism 2 and the discharge end of the drying box 3 being communicated through a lifting device 201, the material output from the drying box 3 being transferred to the chopping mechanism 2 through the lifting device 201 for chopping treatment, it should be noted that the lifting device 201 and the chopping mechanism 2 in the present embodiment are mature existing technologies in the art, and further explanation of their structures and working principles will not be given.

[0022] Based on the structure of the above setting, the papermaking waste residue chopping drying pretreatment device is composed of a pretreatment mechanism 1 and a chopping mechanism 2, wherein the pretreatment mechanism 1 is a pre-breaking and drying mechanism before the papermaking waste residue is chopped, and the chopping mechanism 2 is a waste residue chopping treatment structure after pre-breaking and drying. Specifically, in the working process, the papermaking waste residue enters the breaking box 101, the breaking motor 103 drives the two sets of breaking wheels 102 to rotate to perform pre-breaking treatment on the papermaking waste residue, so that the plastic and twisted ropes contained in the waste residue can be broken, the broken waste residue flows into the distribution box 105, and the distribution motor 106 drives the distribution wheel 107 to rotate to uniformly distribute the broken waste residue in the distribution box 105 onto the conveying belt 5 inside the drying box 3, the conveying motor 503 drives the conveying belt 5 to rotate to convey and move the broken waste residue, and the heating rod 301 installed in the drying box 3 can heat and dry the broken waste residue during the conveying and moving process, thereby realizing the pre-treatment of the papermaking waste residue before chopping, increasing the uniformity and quality of the heating and drying of the waste residue by the heating rod 301 when the waste residue is uniformly laid on the surface of the conveying belt 5, and the waste residue pre-dried by the drying box 3 is discharged into the lifting device 201, which can lift and discharge the pre-broken and pre-dried waste residue into the inside of the chopping mechanism 2, so that the chopping mechanism 2 can chop the pre-broken and dried waste residue. The pre-chopping and pre-drying of the waste residue greatly improves the efficiency and chopping quality of the chopping mechanism 2 during the chopping treatment, and also avoids the situation that the chopping mechanism 2 stops and is damaged due to the winding of plastic or twisted ropes in the waste residue during operation, thereby improving the stability of the chopping mechanism 2 during the chopping treatment of the waste residue.

[0023] Further, a turning installation of a material turning wheel 4 is provided at the central position inside the drying box 3, the material turning wheel 4 is erected above the central position of the conveying belt 5, and a material turning motor 401 fixedly connected with the material turning wheel 4 is fixedly installed at the central position of the front face of the drying box 3.
