DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to solve the problem in the prior art that when the waste crushing device is performing waste crushing work, there may still be some pulp or bamboo fiber required for bamboo pulp paper production in the waste, and the normal crushing device is difficult to remove the pulp from the waste, resulting in waste of raw materials, this embodiment provides the following technical solutions:

[0021] A waste crushing device for bamboo pulp paper production, comprising a fixed base 1, a second rotary bearing 2 is arranged on the fixed base 1, a first rotary motor 3 is arranged on the fixed base 1, a crushing roller 4 is arranged on the first rotary motor 3, and a first rotary bearing 5 is arranged on the crushing roller 4 at one end away from the first rotary motor 3, and also comprising a connecting base 6, the connecting base 6 is arranged on one end away from the first rotary bearing 5, a feed inlet 7 is provided on the connecting base 6, a discharge inlet 8 is provided on the fixed base 1, an outer layer cylinder 9 is arranged on the second rotary bearing 2, a third rotary bearing 21 is arranged on the end of the outer layer cylinder 9 away from the second rotary bearing 2, a transmission belt 11 is arranged on the outer surface of the outer layer cylinder 9, a transmission shaft 12 is arranged on the end of the transmission belt 11 away from the outer layer cylinder 9, limit blocks 13 are arranged at the upper and lower ends of the transmission shaft 12, and the lower end limit block 13 is provided with a second rotary motor 14, and a discharge pipe 10 is arranged at the lower end of the fixed base 1;

[0022] In this embodiment, please refer to Figure 1-Figure 3When the staff puts the waste into the outer cylinder 9 from the feed port 7, the waste contacts the crushing roller 4 first and is crushed by the crushing roller 4. Because there is a gap between the crushing rollers 4, if the waste is thrown to the inner wall of the outer cylinder 9 by the rotating crushing roller 4, the crushing roller 4 in the opposite direction of the outer cylinder 9 applies shear stress to the waste to tear the waste, squeeze out the slurry in the waste, and discharge it along the discharge port 8 opened on the fixed base 1. Because the waste is still driven by the crushing roller 4 to rotate, it will not be discharged from the discharge port 8. Only when the staff turns off the power and the crushing roller 4 stops rotating will the waste be discharged from the discharge port 8. The slurry discharged from the discharge port 8 falls into the collection tank 18 at the lower end along the discharge pipe 10. The staff opens the shut-off valve 20 on the discharge pipe 19 and the slurry can be discharged and can be properly collected by the staff.

[0023] In this embodiment, please refer to Figure 1 A second support column 17 is provided at the lower end of the fixed base 1, and the second support column 17 is welded to the fixed base 1. A collecting tank 18 is provided on the second support column 17, and the collecting tank 18 is welded to the second support column 17. A drain pipe 19 is provided on the collecting tank 18, and the drain pipe 19 is bolted to the collecting tank 18, and a shut-off valve 20 is provided on the drain pipe 19;

[0024] In this embodiment, please refer to Figure 1 A mounting base 15 is provided at the lower end of the second rotating motor 14, the mounting base 15 is bolted to the fixed end of the second rotating motor 14, the mounting base 15 is welded to the fixed base 1, and a first support column 16 is provided at the lower end of the mounting base 15, the first support column 16 is welded to the mounting base 15;

[0025] Working principle: When the staff puts the waste into the outer cylinder 9 from the feed port 7, the waste comes into contact with the crushing roller 4 first and is crushed by the crushing roller 4. Because there is a gap between the crushing rollers 4, if the waste is thrown onto the inner wall of the outer cylinder 9 by the rotating crushing roller 4, the crushing roller 4 in the opposite direction of rotation of the outer cylinder 9 applies shear stress to the waste and tears the waste, squeezing out the slurry in the waste and discharging it along the discharge port 8 opened on the fixed base 1. Because the waste is still rotated by the crushing roller 4, it will not be discharged from the discharge port 8. Only when the staff turns off the power and the crushing roller 4 stops rotating will the waste be discharged from the discharge port 8. The slurry discharged from the discharge port 8 falls into the collection tank 18 at the lower end along the discharge pipe 10. The staff opens the shut-off valve 20 on the discharge pipe 19 and the slurry can be discharged and can be properly collected by the staff.
