[0027] like Figure 1 、 Figure 2 and Figure 3The waste paper recycling hydraulic pulper shown in the figure includes a frame 1, a material pipe 2 is arranged above the frame 1, a feeding motor 3 is arranged at one end of the material pipe 2, and a crushing motor 4 is arranged at the other end of the material pipe 2, the feeding motor 3 is connected to a feeding shaft 31, a spiral sheet 32 ​​is arranged on the feeding shaft 31, and the crushing motor 4 is connected to a crushing shaft 41, a crushing chamber 5 is provided on the material pipe 2, a filter cover 6 is installed in the crushing chamber 5, the end of the crushing shaft 41 inserted into the material pipe 2 extends into the crushing chamber 5, and a crushing device 7 is installed at this end, and the crushing device 7 cooperates with the filter cover 6; a discharge pipe 8 is tangentially arranged at the lower part of the crushing chamber 5, and a discharge valve 81 is installed on the discharge pipe 8; an open slot (not shown) is provided at a position of the material pipe 2 near the feeding motor 3, the open slot is arranged upward, and a hydraulic refinement device is installed at the open slot.

[0028] In the above technical solution, the opening of the discharge valve 81 is adjusted so that some water is always retained in the hydraulic refinement device. After the waste paper is put into the hydraulic refinement device, it is first soaked in the hydraulic refinement device and flushed by the high-speed water flow to complete the softening and refinement of the waste paper. It is then transported by the feed shaft 31 in conjunction with the spiral blade 32. During the transportation process, the waste paper is further refined and compressed. It is then sent to the crushing chamber 5 and polished by the high-speed rotating crushing device 7 to form pulp. After the pulp is refined, it is pressed out from the filter cover 6 and finally discharged from the discharge valve 81.

[0029] In the above technical solution, the waste paper is softened by soaking and flushing with water first, and then the pulp is refined by crushing, which makes the waste paper more reliable.

[0030] See Figure 3 As shown, a cleaning pipe 551 is provided at the upper end of the pulverizing chamber 5 , and a pipe cover 552 is provided at the pipe opening of the cleaning pipe 551 .

[0031] In the above technical solution, the filter cover 6 can be cleaned through the cleaning tube 551 by opening the tube cover 552 .

[0032] See Figure 2 As shown, a first ring body 501 is provided on the side of the crushing chamber 5 close to the feeding shaft 31, a second ring body 502 is provided on the side of the crushing chamber 5 close to the crushing shaft 41, and the filter cover 6 is rotatably provided between the first ring body 501 and the second ring body 502.

[0033] In the above technical solution, the filter cover 6 is arranged to rotate, so that the filter cover 6 can be rotated to achieve cleaning during cleaning.

[0034] See Figure 2 and Figure 4As shown, the filter cover 6 includes a first ring body 601, a second ring body 602 and a filter screen 603. The filter screen 603 is conical and is installed between the first ring body 601 and the second ring body 602. The first ring body 601 is rotatably set in the first ring body 501, and the second ring body 602 is rotatably set in the second ring body 502. A discharge hole 604 is set on the outer wall of the second ring body 602; the crushing device 7 is fitted in the filter screen 603, and the material output from the spiral sheet 32 ​​is refined by the crushing device 7 and discharged from the filter screen 603 or the discharge hole 604.

[0035] In the above technical solution, the pulp is refined by the high-speed rotation of the crushing device 7, and the refined pulp is discharged from the filter screen 603. When the discharge capacity of the filter screen 603 is insufficient, the water pressure in the crushing chamber increases, and the pulp passes through between the filter screen 603 and the crushing device 7, and is discharged from the discharge hole 604 after passing through.

[0036] See Figure 2 and Figure 5 As shown, the crushing device 7 includes a hollow rotating body 701, and an outer conical surface is provided on the outer wall of the rotating body 701. A refinement gap is formed between the outer conical surface and the filter screen 603. The width of the formed refinement gap gradually decreases toward the direction of the crushing axis 41, and refinement cones 702 are evenly distributed on the outer surface of the outer conical surface.

[0037] In the above technical solution, the rotation speed of the rotating body 701 is greater than the rotation speed of the feeding shaft 31. Under the action of the high-speed rotating body 701, the pulp can be quickly broken up by the refining cone 702, and under the action of centrifugal force, the pulp is discharged from the mesh of the filter screen 603.

[0038] See Figure 2 As shown, the end of the feed shaft 31 inserted into the crushing chamber is fixedly installed with a sleeve 331, and a stirring rod 332 is provided on the outer wall of the sleeve 331. The outer wall of the stirring rod 332 is evenly distributed with metal bristles 333, and the metal bristles 333 act on the filter screen 603.

[0039] In the above technical solution, the pulp in the crushing chamber 5 can be stirred by the stirring rod 332, and the cleaning effect of the metal bristles 333 can keep part of the mesh of the filter 603 in a long-term clean state, ensuring that the filter 603 has a sufficient pass rate.

[0040] See Figure 1As shown, the hydraulic refinement device includes a feeding box 901 and a water pump 902. The lower end of the feeding box 901 is connected to the material pipe 2 and corresponds to the open groove. The spiral sheet 32 ​​is partially exposed in the feeding box 901. The water pump 902 is connected to a branch pipe 903. The branch pipe 903 is inserted into the feeding box 901. A high-speed nozzle 904 is provided on the outer wall of the branch pipe 903, and the high-speed nozzle 904 is arranged obliquely downward.

[0041] In the above technical solution, water is pumped into the feed box 901 through the water pump 902, and the water maintains a certain water level. After the water level is maintained, the pumping volume of the water pump 902 is adjusted so that the pumping volume of the water pump 902 is close to the discharge volume of the discharge valve 81. At this time, the waste paper placed in the feed box 901 is soaked and absorbs water, and then softened. The waste paper is then broken up by a high-speed water column and then transported to the pulverizing chamber through the spiral blade 32, so that the waste paper can be pulped more quickly in the pulverizing chamber.

[0042] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
