Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a waste paper processing device for pulping during sea travel. Background Art

[0002] In the current pulp preparation methods, it is necessary to wait for the ship to deliver the required raw materials to the site before building a plant on land for pulping, which results in a long pulping process and high costs. In order to improve this problem, the pulp preparation process can be completed during the sea transportation of the ship, and the waste paper raw materials to be recycled can be transported to the dock. After the ship docks at the dock, the waste paper raw materials can be transported on board, and the pulp can be prepared during the sea transportation of the ship.

[0003] In the process of moving the pulp preparation device to the ship, the wastewater generated by the waste paper treatment has become a new problem. When the pulp is prepared on land, the wastewater is easy to treat. However, during the operation of the ship, the wastewater cannot be discharged directly, and the existing ship wastewater treatment device does not include a method for treating the wastewater generated by the waste paper treatment. Therefore, a waste paper treatment device for pulping during the ship's sea transportation is designed, which utilizes the pulping work during the ship's sea transportation and recycles the generated wastewater for further treatment.

[0014] The utility model is further described below with reference to the accompanying drawings.

[0015] like Figure 1 to Figure 2 As shown, a waste paper feed port 4 is provided at the upper end of the crushing device 1, a water inlet 5 is provided at the side of the crushing device 1, a discharge port 6 is provided at the other end of the crushing device 1, the discharge port 6 is connected to one end of the slag removal device 2 through a pipeline, the other end of the slag removal device 2 is connected to the screening device 3, a pulp outlet is provided on one side of the screening device 3, an inclined waste outlet 7 is provided on the other side of the screening device 3, the waste outlet 7 is connected to a recovery cylinder 8 through a pipeline, a spiral rod 9 is provided in the recovery cylinder 8, a filter element is provided on the surface of the spiral rod 9, the lower end of the recovery cylinder 8 is connected to a waste water cylinder 11 through a recovery pipe 10, and a dosing port 12 is provided at one end of the waste water cylinder 11.

[0016] A return pipe 13 is provided on one side of the recovery drum 8, and both ends of the return pipe 13 are respectively connected to the recovery drum 8, and a water pump is provided on the return pipe 13. When in use, the waste in the recovery drum 8 passes through the screw rod 9 and the filter element for many times through the cooperation of the water pump and the return pipe 13, so as to fully recover the pulp fibers in the waste.

[0017] The return pipe 13 is U-shaped.

[0018] A stirring blade 14 is provided in the waste water cylinder 11, and one end of the stirring blade 14 is connected to a stirring motor 15 to fully stir the waste water and the purification solution.

[0019] The lower end of the crushing device 1 is provided with a residual material outlet 16. When in use, the residual material remaining in the crushing device 1 is cleared out from the residual material outlet 16 and then injected into the waste paper feed port 4 for re-operation, thereby improving the utilization rate of waste paper.

[0020] One end of the screw rod 9 is connected to a rotating motor.

[0021] When the utility model is used, the waste paper raw material is fed from the waste paper feed port 4 into the crushing device 1 for crushing, and the water inlet 5 is connected to the water source, and water is added to the crushing device. The crushed waste paper is mixed with water and then enters the slag removal device 2 for slag removal. After the slag removal is completed, the mixture enters the screening device 3 for coarse screening and fine screening. The screening device 3 is provided with a pulp outlet, and the pulp outlet is connected to the stirring device for further pulp mixing. The waste outlet 7 of the screening device 3 is connected to the recovery cylinder. The waste entering the recovery cylinder passes through the spiral rod 9 and then enters the waste water cylinder 11 through the recovery pipe 10. Waste water treatment liquid is added to the waste water cylinder 11 to purify the waste water. The purified waste water is then uniformly recovered to the centralized waste water treatment place of the ship to wait for centralized treatment.

[0022] When the waste material passes through the spiral rod 9, the pulp fibers in the waste material are intercepted by the filter element. When the filter element intercepts a certain amount of pulp fibers, the filter element is removed to recover the pulp fibers, thereby improving the utilization rate of the waste material.

[0023] The utility model utilizes biological pulping of paper pulp during ship transportation, greatly reduces dependence on land resources, and recycles the generated waste water for further treatment.
