DETAILED DESCRIPTION

[0040] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0041] The utility model provides a waste newsprint pretreatment device, according to the instructions attached Figure 1 To Attachment Figure 5 It can be seen that a waste newsprint pretreatment device mainly includes the following parts or components: a treatment tank 10, an air pump 18, a lifting plate 20, a first stirring shaft 33, and a rotating shaft 34. The connection relationship of each part or component is as follows:

[0042] A filter plate 11 is provided at the bottom of the treatment tank 10 and is connected to a cleaning box 12 below it. A first sealing door 13 and a drain pipe 14 are provided on the cleaning box 12. A foam discharge channel 15 is provided on one side of the treatment tank 10. The first end of the foam discharge channel 15 is connected to the treatment tank 10, and a baffle 16 that can be opened and closed is provided on the second end. A second sealing door 17 that can be opened and closed is provided on the side wall of the treatment tank 10; an air pump 18 is provided on the cleaning box 12, and its air outlet end is connected to the bottom of the treatment tank 10; a lifting plate 20 is provided on the cleaning box 12 under the action of a lifting mechanism 21 and can be lifted and lowered. A first driving shaft 30 that rotates under the drive of a first motor 31 is arranged on the lifting plate 20, and the lower end of the first driving shaft 30 is connected to the middle part of a horizontally arranged connecting rod 32; a first stirring shaft 33 is vertically arranged in the processing tank 10, and its upper end is connected to the middle part of the connecting rod 32; two rotating shafts 34 are vertically arranged in the processing tank 10, and their upper ends are respectively connected to the rotating shafts at both ends of the connecting rod 32, and each rotating shaft 34 is provided with a scraper 35; an adjusting mechanism 40 is arranged on the lifting plate 20 and is connected to the two rotating shafts 34, so as to drive the two rotating shafts 34 to rotate.

[0043] When in use, waste newsprint is placed in the processing tank 10, and clean water and a certain amount of deinking agent are injected. Then the first motor 31 drives the first driving shaft 30 to rotate, driving the first stirring shaft 33 to rotate synchronously, so that the deinking agent is fully in contact with the paper, thereby improving the deinking effect. When the first stirring shaft 33 is stirring, the air pump 18 continuously supplies air to the processing tank 10, and foam is generated during the stirring process. The ink particles are adsorbed on the foam, and the foam is scraped into the foam discharge channel 15 by the scraper 35. When the foam needs to be cleaned, the baffle 16 can be opened to collect it together to prevent the foam from polluting the environment.

[0044] During the stirring process, some newsprint will adhere to the side wall of the processing tank 10 after encountering water. At this time, the two rotating shafts 34 can be driven to rotate by the adjusting mechanism 40, so that the scraper 35 scrapes off the newsprint on the side wall of the processing tank 10 to ensure the deinking effect. In addition, during the stirring process of the first stirring shaft 33 and the scraper 35 in the processing tank 10, the dust on the surface of the newsprint can be cleaned. The dust that falls off will be deposited at the bottom of the cleaning box 12 through the filter plate 11 under the action of gravity. The newsprint will be intercepted in the processing tank 10 above the filter plate 11 to complete the separation. When it is necessary to take out the newsprint, the scraper 35 can be controlled to separate from the side wall of the processing box through the adjusting mechanism 40 after the sewage is discharged. Then, the lifting mechanism 21 drives the lifting plate 20 to rise, thereby separating the first stirring shaft 33 and the scraper 35 from the processing tank 10. After opening the second sealing door 17, it is convenient for the staff to take out the processed newsprint, thereby improving the processing efficiency.

[0045] As an embodiment, according to the attached Figure 4It can be seen that the lifting mechanism 21 includes: a support seat 211 is arranged on the cleaning box 12, and a first guide rod 212 is vertically arranged thereon, and the first guide rod 212 is slidably connected to and penetrates the lifting plate 20; a first screw rod 213 is arranged on the support seat 211 in parallel with the first guide rod 212, and is threadedly connected to and penetrates the lifting plate 20, and the first screw rod 213 can rotate under the drive of the second motor 214.

[0046] When the second motor 214 drives the first screw 213 to rotate, it can drive the lifting plate 20 to rise and fall, thereby adjusting the height of the first stirring shaft 33 and the scraper 35 in the processing tank 10. The screw drive is used to accurately control the height of the lifting plate 20. It has a strong load capacity and can withstand greater pressure and weight, which is convenient for cleaning the processing tank 10 and the first stirring shaft 33.

[0047] As an embodiment, according to the attached Figure 3 It can be seen that the adjustment mechanism 40 includes: a rotating sleeve 41 is sleeved on the first driving shaft 30 and connected to the rotating shaft of the lifting plate 20, and the rotating sleeve 41 can rotate under the drive of the third motor 42; a first adjustment rod 43 is arranged at the lower end of the rotating sleeve 41; two second adjustment rods 44 are respectively arranged at the upper ends of the two rotating shafts 34; the first ends of the two hinged rods 45 are respectively hinged to the two ends of the first adjustment rod 43, and the second ends are respectively hinged to the free ends of the two second adjustment rods 44.

[0048] When the first drive shaft 30 rotates driven by the first motor 31, the third motor 42 drives the rotating sleeve 41 to rotate simultaneously in the same direction and at the same speed, so that the baffle 16 and the connecting rod 32 remain relatively stationary. When it is necessary to drive the baffle 16 to rotate so that the baffle 16 can be against or detached from the side wall of the processing tank 10, the first drive shaft 30 can be controlled to stop rotating first, and then the third motor 42 drives the rotating sleeve 41 to rotate, and then during the rotation, the first adjustment rod 43 can be driven to rotate, and then the two second adjustment rods 44 are driven by the two hinged rods 45 to rotate with the corresponding rotating shafts 34 respectively, so as to adjust the position of the baffle 16. The structure is simple and easy to use.

[0049] As an embodiment, according to the attached Figure 5 It can be seen that a dust cleaning assembly 50 is also provided in the cleaning box 12, which is used to clean the dust in the cleaning box 12 toward the first sealing door 13. The dust cleaning assembly 50 includes: a second guide rod 51 horizontally arranged in the cleaning box 12; a second screw rod 52 and the second guide rod 51 are arranged in parallel in the cleaning box 12, and can rotate under the drive of the fourth motor 53; a cleaning plate 54 is slidably arranged on the second guide rod 51, and is threadedly connected with the second screw rod 52, and the lower end of the cleaning plate 54 is slidably connected with the cleaning box 12.

[0050] After the dust falls into the cleaning box, the fourth motor 53 can drive the second screw 52 to rotate, and then the cleaning plate 54 slides along the second guide rod 51, moving the dust toward the first sealing door 13, making it convenient for staff to clean.

[0051] As an embodiment, a first cylinder is hinged on the foam discharge channel 15, and the end of the first cylinder piston rod is hinged to the baffle 16. The opening and closing of the baffle 16 can be controlled by the first cylinder, and the position of the baffle 16 can be quickly responded to, so as to discharge the foam in the foam discharge channel 15.

[0052] In this embodiment, the surface of the scraper 35 is coated with a rubber coating to reduce the wear between the scraper 35 and the processing tank 10 and extend the service life.

[0053] In this embodiment, according to the specification Figure 1 It can be seen that the second sealing door 17 is provided with an observation window 61 , which is convenient for observing the situation in the processing tank 10 .
