Technical Field

[0001] The utility model relates to the technical field of rotary drum pulpers, in particular to a rotary drum pulper. Background Art

[0002] A drum pulper is a device that uses a high-speed rotating drum to crush waste paper and other raw materials into pulp. It also has a screening function and is particularly suitable for pulping unsorted waste paper raw materials.

[0003] During the use of the current drum pulper, the speed at which the waste paper and other raw materials absorb water by themselves is slow, resulting in reduced pulping efficiency and increased energy consumption. For this reason, we propose a drum pulper. Utility Model Content

[0004] The utility model aims to provide a rotary drum pulper, which has the advantages of being able to improve the efficiency of water absorption and infiltration of waste paper and other raw materials, thereby improving the efficiency of subsequent pulping and facilitating the subsequent cleaning of the inside of the rotating drum, and solves the problem that during the use of the current rotary drum pulper, the efficiency of pulping is reduced and the energy consumption is increased due to the slow self-absorption of water and infiltration of waste paper and other raw materials.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rotary drum pulper comprises a rotary drum and a filter hole, a rotary sleeve is rotatably connected to one side of the outer surface of the rotary drum, a feed pipe is welded to the upper surface of the rotary sleeve, a hollow rotary shaft is rotatably installed on the outer side of the rotary sleeve, one end of the hollow rotary shaft located outside the rotary sleeve is rotatably connected to a mixing tube through a rotary joint, a one-way water valve is fixedly connected to the end of the mixing tube, a water inlet pipe is fixedly connected to the end of the one-way water valve, a one-way air valve is fixedly connected to the outer surface of the mixing tube, a compressed air pipe is fixedly connected to the end of the one-way air valve, an injection hole is provided on the outer surface of the hollow rotary shaft, and the injection hole is located inside the rotary drum.

[0006] Preferably, a feed hopper is welded on the upper surface of the feed pipe.

[0007] Preferably, a filter hole is provided on the side of the outer surface of the rotating drum facing away from the rotating sleeve, and the filter hole plays a role in screening the pulp and removing impurities in the pulp.

[0008] Preferably, a transmission box is fixedly mounted on the outer side of the rotating sleeve, and the hollow rotating shaft passes through the transmission box.

[0009] Preferably, a rotating motor is fixedly mounted on the outer surface of the transmission box, a motor gear is fixedly connected to the end of the output shaft of the rotating motor, a transmission gear is fixedly sleeved on the outer surface of the hollow rotating shaft, and the transmission gear and the motor gear are meshed, the transmission gear and the motor gear are both located inside the transmission box, and the rotating motor drives the hollow rotating shaft to rotate via the motor gear and the transmission gear.

[0010] Preferably, a spiral blade is welded on the outer surface of the hollow rotating shaft, and the spiral blade is located inside the rotating sleeve. The spiral blade rotates to force the waste paper and other raw materials inside the rotating sleeve to enter the rotating drum.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model achieves the effect of improving the water absorption and infiltration efficiency of waste paper and other raw materials by arranging a water inlet pipe, a mixing pipe, a compressed air pipe, a hollow rotating shaft and a rotating sleeve, thereby improving the efficiency of subsequent pulping and facilitating the subsequent cleaning of the inside of the rotating drum. The waste paper and other raw materials enter the inside of the rotating sleeve through the feed pipe and then enter the inside of the rotating drum, while water and chemical reagents are transported to the inside of the hollow rotating shaft from the water inlet pipe. At the same time, compressed air is input into the inside of the hollow rotating shaft from the compressed air pipe, and the compressed air and water are sprayed out from the spray hole and sprayed onto the waste paper and other raw materials, so that the waste paper and other raw materials quickly absorb water and infiltrate, thereby improving the subsequent pulping efficiency. When cleaning the inside of the rotating drum, clean water enters from the water inlet pipe, and the cleaning of the inside of the rotating drum is completed in the same way.

[0013] 2. The utility model achieves the effect of facilitating the entry of waste paper and other raw materials into the rotating drum through the rotating sleeve by arranging spiral blades, a rotating motor and a transmission box. The rotating motor drives the hollow rotating shaft to rotate through the motor gear and the transmission gear, thereby driving the spiral blades to rotate, forcing the waste paper and other raw materials inside the rotating sleeve to enter the rotating drum.
