[0002] As people pay more and more attention to environmental protection, reducing the impact of waste on the environment has become an important issue. Waste cartons are a common solid waste. If a large number of waste cartons are not properly handled, they will cause environmental pollution, such as occupying land and affecting the landscape.

[0003] By pulping, recycling and compressing waste cardboard boxes, resources can be reused and the demand for virgin wood and other resources can be reduced, which is in line with the concept of sustainable development.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figure 1 - Figure 8 As shown, this embodiment is a pulping and recycling device based on the processing of waste paper boxes, comprising a recycling cylinder 1, a cylinder cover 2 is arranged on the top of the recycling cylinder 1, an inner rotating shaft body 6 extending to the inside of the recycling cylinder 1 is penetrated in the middle of the cylinder cover 2, a partition gate valve 3 is arranged on the bottom of the outer peripheral wall of the recycling cylinder 1, a compression bottom box 5 is arranged at the bottom of the recycling cylinder 1, and a rotating cover plate 602 rotatably sleeved with the inner wall of the recycling cylinder 1 is arranged in the middle of the shaft body of the inner rotating shaft body 6;

[0032] When the waste paper boxes are broken into pieces and enter the pulping equipment for soaking and stirring, the broken paper is soaked and stirred, and then the pulp is extracted through the relevant equipment and transported to the recovery cylinder 1, and the pulp is poured into the recovery cylinder 1 along the feed pipe 202.

[0033] A reinforcing hoop 101 is provided in the middle of the outer wall of the recovery cylinder 1, an inner bracket 104 is provided in the middle of the inner wall of the recovery cylinder 1, and a plurality of groups of through-holes 103 are symmetrically provided at the bottom of the outer wall of the recovery cylinder 1. An overflow ring 102 is provided on the outer wall of the recovery cylinder 1 below the through-holes 103, and filter holes and filter screens extending to the inner wall of the recovery cylinder 1 are provided on the inner wall of the overflow ring 102.

[0034] A servo motor 201 is arranged on the top of the cylinder cover 2, and a socket is arranged at the center of the top of the cylinder cover 2 for socketing with the top of the inner rotating shaft body 6, and the output end of the servo motor 201 is transmission connected with the inner rotating shaft body 6 via the socket, and a feed pipe 202 is arranged on the side of the servo motor 201, which penetrates the cylinder cover 2 and extends to the inside of the recovery cylinder body 1. When the servo motor 201 is started, the servo motor 201 is transmission connected with the inner rotating shaft body 6 via the coupling and the socket, thereby driving the inner rotating shaft body 6 to rotate.

[0035] An upper spiral disk 601 is arranged on the top shaft body of the inner rotating shaft body 6, a lower spiral disk 603 is arranged on the bottom shaft body of the inner rotating shaft body 6, a support sleeve 604 sleeved on the bottom of the inner rotating shaft body 6 is arranged below the lower spiral disk 603, and a support rod connected to the recovery cylinder 1 is arranged on the outer periphery of the support sleeve 604;

[0036] During the rotation of the inner rotating shaft 6, the pulp firstly pours into the inside of the recovery cylinder 1 and falls on the surface of the upper spiral disk 601. With the continuous rotation of the upper spiral disk 601, the pulp slides along the surface of the upper spiral disk 601 and accelerates to flow toward the rotating cover disk 602. When it leaves the upper spiral disk 601, the pulp contacts the spiral frame bars 605 and is affected by the spiral frame bars 605 and explodes between the upper spiral disk 601 and the rotating cover disk 602. Part of the pulp flows to fill the upper leakage port 606. When the upper leakage port 606 fits with the lower leakage port 608, the part of the pulp falls between the upper leakage port 606 and the lower leakage port 608 onto the lower spiral disk 603. During this period, the upper leakage port 606 continues to rotate with the rotating cover disk 602, and the pulp in the upper leakage port 606 is cut off and processed.

[0037] At the beginning of the operation of the recovery cylinder 1, the servo motor 201 reduces the driving speed of the inner rotating shaft 6, and then the amount of pulp poured into the feed pipe 202 exceeds the flow rate of the upper leakage port 606 and the lower leakage port 608, so that the pulp between the upper spiral disk 601 and the rotating cover disk 602 gradually accumulates to a certain amount, and then the driving rotation speed of the inner rotating shaft 6 is accelerated by the servo motor 201, thereby maintaining a balance between the incoming amount and the outgoing amount.

[0038] The bottom of the rotating cover plate 602 is sleeved with a fixed tray 607, the top of the rotating cover plate 602 is provided with multiple sets of spiral racks 605, the surface of the rotating cover plate 602 is penetrated with multiple sets of upper leaks 606, and the surface of the fixed tray 607 is penetrated with lower leaks 608 symmetrical to the upper leaks 606;

[0039] When the amount of pulp accumulated on the rotating cover plate 602 overflows the lower half of the upper spiral plate 601, the pulp is pushed down by the continuous rotation of the upper spiral plate 601, thereby increasing the pressure of the accumulated pulp between the upper spiral plate 601 and the rotating cover plate 602. The rotating cover plate 602 continues to rotate, and the spiral frame bars 605 are driven to rotate accordingly, and the pressurized pulp in this area is spirally crushed, so that the pulp is further crushed after soaking.

[0040] Wait for the pulp to enter the surface of the lower spiral disk 603 along the lower leakage port 608, and flow to the compression bottom box 5 along with the rotation of the lower spiral disk 603. The pulp is collected in the compression bottom box 5. During this period, the pump 506 is started. The pump 506 is connected to the water collecting ring 504 and the overflow ring 102 through a dedicated pipeline. A pipeline connected to the external wastewater tank is set at the bottom of the pump 506. The water collecting ring 504 is used to extract water from the pulp in the compression bottom box 5 near the seepage inner cylinder 502 area to accelerate the moisture in the pulp, so that the pulp is compressed and deposited in the compression bottom box 5, and the subsequent pulp is pushed along with the continuous rotation of the lower spiral disk 603, so that the pulp is collected at the bottom of the recovery cylinder 1 and the compression bottom box 5 under the driving force of the rotation of the lower spiral disk 603.

[0041] Embodiment 2: This embodiment is a pulping and recycling device based on waste paper box processing, including a secondary gate valve 301 penetrating the recovery cylinder 1 and arranged side by side on the end face of the isolation gate valve 3, a lifting cylinder 4 connected to the bottom of the outer peripheral wall of the recovery cylinder 1 is arranged on the outer walls of both sides of the compression bottom box 5, and an inner tray 503 is arranged inside the compression bottom box 5;

[0042] The end face of the isolating gate valve 3 is provided with a disc gate piece 302 inserted into the through-hole 103, and the inner walls on both sides of the isolating gate valve 3 are provided with a pushing cylinder 1 connected to the disc gate piece 302. The end face of the auxiliary gate valve 301 is provided with a strip gate piece 303 passing through the through-hole 103, and the two sides of the auxiliary gate valve 301 are provided with a pushing cylinder 2 connected to the strip gate piece 303. The disc gate piece 302 is provided with a connecting groove adapted to the strip gate piece 303 at one end close to the auxiliary gate valve 301, and a combination hole for sleeved inner rotating shaft body 6 is provided between the connecting groove and the end face of the strip gate piece 303.

[0043] When a large amount of pulp is collected at the bottom of the recovery cylinder 1, and the pulp inside the compression bottom box 5 has been continuously sucked and precipitated by the water-seeping inner cylinder 502, the push cylinders on both sides of the isolation gate valve 3 are started, and the push cylinders drive the disc gate piece 302 to enter the recovery cylinder 1 along the through opening 103, isolating most of the area between the bottom of the recovery cylinder 1 and the compression bottom box 5, so that the pulp continuously pushed by the lower spiral disk 603 is pressurized in the connecting groove of the disc gate piece 302 and enters the compression bottom box 5, so that the pulp inside the compression bottom box 5 is further compressed;

[0044] As the seepage inner cylinder 502 continuously pumps water from the compression bottom box 5, and the overflow ring 102 coordinates to pump water from the pulp near the area below the disc gate piece 302, the pulp between the compression bottom box 5 and the disc gate piece 302 is further compressed, and the auxiliary gate valve 301 is started after timing. The auxiliary gate valve 301 drives the strip gate piece 303 along the through hole 103 into the recovery cylinder 1 by pushing the cylinder 2, and is matched with the connecting groove. With the inner rotating shaft body 6 as the central axis, the internal chamber at the bottom of the recovery cylinder 1 is separated from the upper and lower parts. In this state, the continuous input amount of external pulp and the rotation rate of the inner rotating shaft body 6 are reduced, and the inner rotating shaft body 6 can even be kept suspended.

[0045] A sealing groove 501 connected to the recovery cylinder 1 is provided in a recessed manner at the top of the compression bottom box 5, a water seepage inner cylinder 502 is provided on the inner wall of the compression bottom box 5, and a water collecting ring 504 connected to the water seepage inner cylinder 502 is provided at the bottom edge of the outer wall of the compression bottom box 5, a pump 506 is provided on the inner side of the water collecting ring 504, an inner tray 503 is provided on the inner bottom wall of the compression bottom box 5, a lifting cylinder 505 is provided at the bottom center of the outer wall of the compression bottom box 5, and the lifting cylinder 505 is connected to the inner tray 503, and a rotating motor 507 connected to the lifting cylinder 4 is provided on the outer peripheral walls on both sides of the compression bottom box 5.

[0046] After the pulp inside the compression bottom box 5 is fully compressed and dried by pumping, the lifting cylinder 4 drives the compression bottom box 5 to slide down through the rotating motor 507 until the compression bottom box 5 is separated from one end of the bottom of the recovery cylinder 1. In this state, the compressed pulp in the compression bottom box 5 is synchronously separated from the recovery cylinder 1 under the action of its own weight and traction. The rotating motor 507 drives the compression bottom box 5 to rotate along the bottom of the lifting cylinder 4 through the coupling and the adapter until the compression bottom box 5 flips over. The compacted pulp begins to slide down under the action of its own weight, and the lifting cylinder 505 drives the inner tray 503 to extend axially along the inside of the compression bottom box 5, further pushing the pulp out of the compression bottom box 5. The dehydrated recovered pulp is collected by the conveying equipment or container located under the recovery cylinder 1, so that it is convenient to transport it to the next step for processing.

[0047] Combining the first and second embodiments, it can be known that the waste paper boxes can be efficiently converted into pulp through the steps of crushing, soaking, stirring, etc., thereby improving the resource utilization rate. The application and speed adjustment of the servo motor 201 can realize the automatic control of the pulp processing; at the same time, the cooperation of the upper, middle and lower spiral discs 603 and the spiral frame strips 605 can ensure the fine crushing of the pulp and improve the pulp quality.

[0048] In addition, the synergistic effect of the pump 506, the water collecting ring 504, the overflow ring 102 and the water seepage inner cylinder 502 accelerates the drying of the pulp and reduces energy consumption. Finally, the cooperation between the lifting cylinder 4 and the rotating motor 507 makes it easy to separate and collect the compressed pulp, which facilitates subsequent processing and greatly improves the recovery rate and reuse efficiency of the pulp.
