This patent provides a separation device and a cleaning device in a filter box. The separation device separates the shredded waste paper, the cleaning device is used to scrape off the larger waste paper and impurities on the separation device, and the collecting device is used to collect the larger waste paper and impurities, so as to achieve the purpose of separating impurities in the waste paper shredding processing; the utility model has a reasonable and practical structure and is easy to use. It is not only convenient to screen the shredded waste paper to prevent clogging during screening, but also convenient to collect the screened waste paper and impurities. However, it is impossible to separate impurities of the same size as the waste paper scraps, and at the same time, the paper scraps and impurities are mixed and cannot be effectively separated.

[0014] 1) The impurity separation device for waste paper shredding of the utility model is provided with an airflow fan, a first filter screen and a second filter screen. By starting the airflow fan to draw air in a positive direction outward, lighter paper is floated up under the influence of the airflow, and the broken paper scraps are adsorbed on the outer wall of the second filter screen, while smaller impurities with heavier mass cannot be drawn by the airflow and cannot be adsorbed on the second filter screen, thereby completing the separation of paper scraps and impurities of the same size, which is beneficial to separating impurities and paper scraps of the same size according to their weight, and is beneficial to preventing smaller impurities and paper scraps from mixing and entering the next process.

[0021] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative, and the structures involved in the present invention are not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0022] Example:

[0023] See also Figure 1-4 The utility model provides a technical solution: an impurity separation device for waste paper shredding, comprising a shell 1, a feed port is installed at the rear end of the shell 1, and is characterized in that: a first filter screen 2 is installed on the top of the shell 1, a second filter screen 12 is installed below the first filter screen 2, an air flow fan 7 is installed between the first filter screen 2 and the second filter screen 12, and the air flow fan 7 can rotate forward and reversely, a left channel 5 and a right channel 13 are installed on the left and right sides of the shell 1, respectively, a drive seat 8 is installed on the left and right sides of the shell 1, a motor 11 is installed inside the drive seat 8, and the shaft of the motor 11 is connected to an opening and closing plate 9, and the air flow fan 7 is started to rotate forward and outward to draw air, so that the lighter paper is affected by the air flow. The broken paper scraps float up, and the broken paper scraps are adsorbed on the outer wall of the second filter screen 12, while the smaller impurities with heavier mass cannot be pulled by the airflow and cannot be adsorbed on the second filter screen 12, thereby completing the separation of paper scraps and impurities of the same size. When the airflow fan 7 is started to rotate forward to complete the separation of paper scraps, and the airflow decays, it means that a large amount of paper scraps are adsorbed on the second filter screen 12, and then the motor 11 inside the driving seat 8 is started, and then the opening and closing plate 9 is driven to be horizontally placed to expose the left channel 5 and the right channel 13, and then the airflow fan 7 is started to blow air inward in the opposite direction, and then the paper scraps adsorbed on the second filter screen 12 are impacted by the airflow and enter the exposed left channel 5 and right channel 13, and then the paper scraps are discharged from the paper outlet 6, and the separation of paper scraps and impurities is quickly completed.

[0024] Among them, a slope 14 is provided at the bottom of the left channel 5 and the right channel 13, and the front ends of the left channel 5 and the right channel 13 are connected to the paper outlet 6 corresponding to the paper outlet. The slope 14 allows the paper scraps to move quickly toward the paper outlet 6 at an inclined angle, and the paper scraps are finally discharged from the paper outlet 6.

[0025] The filtering size of the second filter screen 12 is smaller than that of the first filter screen 2 . The size of the second filter screen 12 needs to be smaller than that of paper scraps to prevent paper scraps from passing through the second filter screen 12 . The first filter screen 2 needs to ensure the air intake.

[0026] Among them, an outlet is opened at the bottom of the shell 1, and an opening and closing shielding plate 10 is installed at the outlet. The opening and closing method of the shielding plate 10 is the same as the opening and closing method of the opening and closing plate 9. The bottom outlet of the shell 1 is used to discharge impurities from the outlet. The shielding plate 10 also has a driving seat 8 and a motor 11. The shielding plate 10 is driven by the motor 11 to rotate and open and close, or it can be pulled and locked.

[0027] When the air flow fan 7 rotates forward to draw air outward, the motor 11 drives the opening and closing plate 9 to block the left channel 5, i.e. to place it upright. By starting the air flow fan 7 to draw air outward in the forward direction, lighter paper floats up under the influence of the air flow, and the broken paper scraps are adsorbed on the outer wall of the second filter 12, while smaller impurities with heavier mass cannot be drawn by the air flow and cannot be adsorbed on the second filter 12.

[0028] When the air flow fan 7 is reversed to blow air inward, the motor 11 drives the opening and closing plate 9 to close the bottom of the shell 1, that is, to place it horizontally. When the second filter 12 absorbs a large amount of paper scraps, the air flow fan 7 is started to turn forward and draw air outward, so that the lighter paper floats up due to the influence of the air flow, and the broken paper scraps are absorbed by the outer wall of the second filter 12, while the smaller but heavier impurities cannot be pulled by the air flow and cannot be absorbed by the second filter 12.

[0029] Among them, a bracket 3 is installed on the top of the shell 1, and an airflow mark 4 is installed in the middle of the bracket 3. The position of the airflow mark 4 corresponds to the position of the airflow fan 7. The middle part of the airflow mark 4 is a bearing structure. When the airflow fan 7 is started, the airflow mark 4 starts to rotate under the influence of the airflow. The strength of the airflow can be intuitively judged by the rotation speed of the airflow mark 4.

[0030] The working principle of the embodiment of the utility model is as follows: when the airflow fan 7 is started, the airflow mark 4 starts to rotate under the influence of the airflow, and the strength of the airflow can be intuitively judged by the rotation speed of the airflow mark 4. By starting the airflow fan 7 to rotate forward and draw air outward, the lighter paper is affected by the airflow and floats up, and the broken paper scraps are adsorbed on the outer wall of the second filter screen 12, while the smaller but heavier impurities cannot be pulled by the airflow and cannot be adsorbed on the second filter screen 12, thereby completing the separation of paper scraps and impurities of the same size. After the airflow fan 7 is started to rotate forward to complete the separation of paper scraps, and the airflow is attenuated, it means that a large amount of paper scraps are adsorbed on the second filter screen 12, and then the motor 11 inside the driving seat 8 is started, and then the opening and closing plate 9 is driven to be horizontally placed to expose the left channel 5 and the right channel 13, and then the airflow fan 7 is started again to blow air inward in the opposite direction, and then the paper scraps adsorbed on the second filter screen 12 are impacted by the airflow and enter the exposed left channel 5 and the right channel 13, and then the paper scraps are discharged from the paper outlet 6, and the separation of paper scraps and impurities is quickly completed, and the impurities are discharged from the outlet of the shell 1 by opening the shielding plate 10.
