Description

Technical Field

[0001] This application belongs to the technical field of material recycling and reuse devices, and particularly relates to a water receiving component and a crushing and recycling device including the component. Background Technology

[0002] Generally, paper materials with relatively low confidentiality levels can be destroyed by shredding them into a relatively large number of thin strips, which is sufficient to meet confidentiality requirements.

[0003] However, the above-mentioned shredding methods are not suitable for highly classified documents. For such documents, the appropriate destruction methods are mainly incineration and disintegration in water. The disadvantage of the former is that the relevant safety requirements for incineration operations are relatively high, and the limitations may be relatively large. At the same time, the latter can both shred the paper and wash it away, thus achieving a thorough destruction. The main advantage of the latter is that the paper material can be recycled and reused in the form of fibers.

[0004] Accordingly, the paper material crushing and recycling device based on the above-mentioned water-dispersing method mainly consists of a crushing chamber that can be filled with water, and a spiral blade extrusion cylinder. Paper and water are added together into the crushing chamber to obtain a liquid paper fiber material. The liquid material then undergoes a dewatering process by the spiral blade extrusion cylinder to obtain a final, relatively dry, reusable compressed block of paper fibers.

[0005] For example, Chinese utility model patent with authorization announcement number CN221297413U and authorization announcement date of July 9, 2024 discloses a water filtration device, whose main structural components include: a water filter screen cylinder, a side wall, a rotating shaft, a motor, a discharge port, a positioning plate, a connecting rod, spiral blades, a discharge plate, a spring, a feed port, and a conveying bin.

[0006] The advantages of the moisture filtration device in this utility model patent are mainly: the feeding station of the feeding hopper plays a role in limiting the amount of pulp fed, avoiding damage to the rotating shaft caused by excessive impact due to the direct injection of a large amount of pulp.

[0007] However, in actual use, this moisture removal device still has at least the following shortcomings in practicality and relatively low efficiency, specifically including: First, water will fall and be pressed out along the entire length of its filter screen structure, and existing common containers such as buckets are unable to fully receive the water, ultimately leading to pollution of the operating environment. Secondly, the pre-drainage function provided at the location of its drain pipe is insufficient, and it cannot pre-drain most of the water in the paper fiber liquid. This means that the motor-driven squeezing drainage operation must undertake a relatively large workload, which is not efficient and flexible. Utility Model Content

[0008] This application provides a water-receiving component, the technical problem of which is to make the dewatering operation of paper fiber liquid more clean, flexible and efficient when destroying confidential paper materials by dispersing them in water.

[0009] In addition, this application also provides a crushing and recycling apparatus including the above-mentioned components.

[0010] The technical solution adopted by this application to solve the above problems is: a water receiving component, the structure of which includes an open cylinder unit sleeved on the water filter cylinder and used to receive squeezed water and stagnant water, an inclined plate disposed on the open cylinder unit and used to guide stagnant water into the open cylinder unit, and a drain pipe disposed on the open cylinder unit.

[0011] A further preferred technical solution is that the open cylinder unit includes a transverse cylinder sleeved on the filter cylinder, a lengthwise through-cut on the transverse cylinder with the inclined plate on one side for inserting and installing the filter cylinder, and a drain outlet at the bottom of the transverse cylinder for installing the drain pipe.

[0012] A further preferred technical solution is that the open cylindrical unit further includes two arc-shaped waterproof strips respectively disposed at both ends of the transverse cylinder and used to clamp the cylinder flange.

[0013] A further preferred technical solution is that the open cylindrical unit further includes two radial protrusions respectively disposed at both ends of the transverse cylinder, and insertion holes disposed on the radial protrusions for circumferentially fixing the transverse cylinder by inserting flange bolts.

[0014] A further preferred technical solution includes two water baffles respectively disposed at both ends of the inclined plate.

[0015] A further preferred technical solution includes a combined pipe unit that is sleeved on the drain pipe and vertically supported for circumferentially fixing the open cylindrical unit.

[0016] A further preferred technical solution is that the combined pipe unit includes a supporting outer pipe sleeved on the drain pipe, a lower end sealing plate disposed on the supporting outer pipe, and a side outlet pipe disposed on the supporting outer pipe.

[0017] A further preferred technical solution is that the combined tube unit further includes an internal vertical rod disposed on the lower end sealing plate, and a radial rod disposed on the internal vertical rod for intercepting paper fibers.

[0018] A crushing and recycling device including the water receiving component, the structure further includes a water filter cylinder, a cylinder flange, and flange bolts, and a support plate disposed on the cylinder flange and located above the open cylinder unit, a filter frame disposed on the support plate for settling paper fiber liquid material before the squeezing and draining operation, and a single-sided filter hole disposed on the side plate of the filter frame for discharging the settling water onto the inclined plate.

[0019] A further preferred technical solution includes: a feed inlet disposed on the filter cylinder and located on both sides of the filter cylinder, and a transverse cross section disposed on the cylinder flange and used for mounting the support plate.

[0020] The beneficial effects of this application include at least the following six points.

[0021] First, the water receiving component can provide a sufficient effective water receiving area for the squeezing drainage operation, preventing the squeezing water from spilling and polluting the operating environment. It can also allow the static drainage operation to be carried out as needed, ensuring that the static water is fully received.

[0022] Secondly, in this crushing and recycling device, the inclined plate and the feed inlet are located on the two sides respectively, ensuring that the feeding actions of the static drainage operation and the squeezing drainage operation do not affect each other.

[0023] Third, the instability caused by the impact of the inclined plate during the static drainage operation is fully resolved. The insertion hole and the combined pipe unit can effectively prevent the open cylinder unit from undergoing harmful circumferential rotation, ensuring that the entire drainage operation is carried out efficiently and safely.

[0024] Fourth, the modular tube unit can not only vertically support the open tube unit, but also prevent the latter from rotating in the same direction. It can also properly intercept paper fibers, making the paper fiber recycling operation more comprehensive. Moreover, the blockage problem at the modular tube unit is easier to solve.

[0025] Fifth, the crushing and recycling device can provide sufficient positional stability for the static drainage operation and does not affect the subsequent squeezing drainage operation. It can even allow the squeezing drainage operation of the previous batch of paper fiber liquid and the static drainage operation of the next batch of paper fiber liquid to be carried out simultaneously, which greatly improves the efficiency of the entire dewatering operation.

[0026] Sixth, the water receiving component can also be used to backwash the filter cylinder by adding water at the inclined plate, so that the paper fibers on the filter holes can be fully removed and recycled, further improving the efficiency of paper fiber recycling operation.

Detailed Implementation

[0036] The following description is merely a preferred embodiment of this application and is not intended to limit the scope of this application.

[0037] like Figures 1-7As shown, a water receiving assembly includes an open cylindrical unit 1 sleeved on a filter cylinder 11 for receiving squeezed water a and still water b, an inclined plate 2 disposed on the open cylindrical unit 1 for guiding the still water b into the open cylindrical unit 1, and a drain pipe 3 disposed on the open cylindrical unit 1.

[0038] In this embodiment, the main body of the water receiving assembly is made of plastic, such as TPE or PC, which has sufficient weather resistance and suitable elasticity. The length of the open cylindrical unit 1 is 1-2 cm shorter than the length of the filter cylinder 11. During normal use, both ends of the open cylindrical unit 1 properly and adequately abut against the two cylinder flanges 12, preventing significant leakage at the gaps between the open cylindrical unit 1 and the cylinder flanges 12.

[0039] When the water receiving assembly is in normal use, the opening of the open cylindrical unit 1 should generally face upwards. On the circumferential direction of the open cylindrical unit 1, the inclined plate 2 is located diagonally above one side, and the drain pipe 3 is located at its lowest point.

[0040] In this way, the liquid paper fiber can first be allowed to stand and drain at the inclined plate 2, and then be discharged in an orderly manner through the drain pipe 3. Then, it can be squeezed and drained in the filter cylinder 11, and also discharged in an orderly manner through the drain pipe 3. This ensures that when the confidential paper material is destroyed by dispersing in water, the paper fiber can be efficiently recycled and reused. This is extremely important for the destruction of large quantities of paper material and has high economic value.

[0041] On the other hand, the open cylindrical unit 1, the inclined plate 2, and the drain pipe 3 are integrally formed. The opening of the open cylindrical unit 1 is appropriately widened so that the water receiving component can be installed and removed from the water filter cylinder 11. The inner diameter of the open cylindrical unit 1 is 4-8 cm larger than the outer diameter of the water filter cylinder 11, ensuring that water can be discharged between the two as quickly as possible.

[0042] The open cylindrical unit 1 includes a transverse cylinder 101 sleeved on the filter cylinder 11, a lengthwise through-cut 102 disposed on the transverse cylinder 101 with the inclined plate 2 on one side for inserting and installing the filter cylinder 11, and a drain outlet 103 disposed at the bottom of the transverse cylinder 101 for installing the drain pipe 3.

[0043] In this embodiment, the central angle of the open cylindrical unit 1 is ≥300°, and the filter cylinder 11 can have filter holes only at the lower position on it, or it can have them all around 360°.

[0044] The number and position of the drain outlets 103 correspond to the drain pipe 3. The inclined plate 2 can be directly set on one side of the through cut 102 along its length. In the axial direction of the transverse cylinder 101, the length of the inclined plate 2 is less than or equal to its length.

[0045] The open cylindrical unit 1 also includes two arc-shaped waterproof strips 104, which are respectively disposed at both ends of the transverse cylindrical 101 and used to clamp the cylindrical flange 12.

[0046] In this embodiment, the arc-shaped waterproof strip 104 is made of common rubber, which is bonded to the end face of the transverse cylinder 101, or has a U-shaped cross-section and is stuck at the end of the transverse cylinder 101.

[0047] Furthermore, the circumferential length of the arc-shaped waterproof strip 104 should be less than or equal to the circumferential length of the end face of the transverse cylinder 101, ensuring that the liquid level of the squeezed water body a and / or the stationary water body b does not exceed the entire arc-shaped waterproof strip 104. At this point, the arc-shaped waterproof strip 104 is fully compressed by the transverse cylinder 101 and the cylinder flange 12, ensuring that the entire water-receiving assembly is not prone to leakage.

[0048] The open cylindrical unit 1 also includes two radial protrusions 105 respectively disposed at both ends of the transverse cylinder 101, and insertion holes 106 disposed on the radial protrusions 105 and used to circumferentially fix the transverse cylinder 101 by inserting flange bolts 13.

[0049] In this embodiment, the radial protrusion 105 is an integral structure in the shape of a fan ring, as shown in the attached figure. Figure 3 As shown, multiple bolts can be used, either individually or in rectangular, semi-circular, or irregular shapes. Both methods can achieve the insertion relationship between the insertion hole 106 and the flange bolt 13, ultimately preventing unnecessary circumferential rotation of the already installed transverse cylinder 101.

[0050] In addition, it should be noted that: First, when installing the water receiving component, it is not necessary for the flange bolts 13 to be installed before or after installation. If the latter is installed later, the installation method of the former is relatively simple. It is only necessary to first insert the transverse cylinder 101 and then align the flange bolts 13 and the insertion hole 106. However, if the latter is installed first, the installation method of the former is relatively complicated. The transverse cylinder 101 needs to undergo flaring deformation at the through cut 102 and bending deformation in axial length simultaneously or sequentially in order to allow the water filter cylinder 11 to be inserted into the transverse cylinder 101 and the flange bolts 13 to be inserted into the insertion hole 106. Secondly, no thread is required at the insertion hole 106. If it were a threaded hole, the "install the latter first" method mentioned in the first point would be difficult to implement, reducing its practicality.

[0051] The structure of the water receiving assembly also includes two water baffles 4 respectively disposed at both ends of the inclined plate 2.

[0052] In this embodiment, the main function of the baffle plate 4 is to ensure that all the static water body b falls into the horizontal cylinder 101 and is eventually collected in an orderly manner at the drain pipe 3.

[0053] The structure of the water receiving assembly also includes a combined pipe unit 5 that is sleeved on the drain pipe 3 and is vertically supported for circumferentially fixing the open cylindrical unit 1.

[0054] In this embodiment, the main body material of the combined pipe unit 5 is also the aforementioned plastic, and the sealing performance between it and the drain pipe 3 is achieved by existing common sealing rings to avoid a large amount of water leakage between the two.

[0055] The term "combined" in the combined tubular unit 5 corresponds to at least the following two functions: First, the horizontal cylinder 101 is vertically supported, especially to prevent the middle part of the latter from bending and deforming downwards. Otherwise, the side of the through cut 102 will be very close to the water filter cylinder 11, so that the still water b cannot fall completely from the inclined plate 2 into the horizontal cylinder 101, resulting in the operation site being contaminated. Secondly, similar to the function of the insertion hole 106, it also serves to circumferentially fix the transverse cylinder 101 to prevent the height of any side of the through cut 102 from being too low, otherwise the squeezed water a and / or the still water b will overflow from that side.

[0056] The combined pipe unit 5 includes a supporting outer pipe 501 sleeved on the drain pipe 3, a lower end sealing plate 502 disposed on the supporting outer pipe 501, and a side outlet pipe 503 disposed on the supporting outer pipe 501.

[0057] In this embodiment, the supporting outer tube 501 is sleeved on the outer ring surface of the drain pipe 3, and a sealing ring is provided between the two. The supporting outer tube 501, the lower sealing plate 502, and the side water outlet pipe 503 can be integrally formed, and the overall shape is T-shaped.

[0058] The lower sealing plate 502 rests against the ground or work surface, and can serve as an auxiliary or secondary position to restrict the circumferential rotation of the transverse cylinder 101.

[0059] On the other hand, the main function of the side water outlet pipe 503 is to change the water outlet method of the water receiving component from the original downward type to the side type. This is extremely practical when the horizontal cylinder 101 is close to the ground or the work surface, ensuring that the water pipes to be connected later have sufficient installation space.

[0060] The combined tube unit 5 also includes an internal vertical rod 504 disposed on the lower end sealing plate 502, and a radial rod 505 disposed on the internal vertical rod 504 for intercepting paper fibers c.

[0061] In this embodiment, the combined tube unit 5 can also be formed by inserting or screwing the lower sealing plate 502 and the supporting outer tube 501 together, and the lower sealing plate 502, the inner vertical rod 504 and the radial rod 505 can be integrally formed, so that the paper fibers c intercepted on the latter two can be easily recycled.

[0062] On the other hand, another function of the overall structure of the vertical rod 504 and radial rod 505 inside the pipe is to prevent paper fibers c from clogging the side water outlet pipe 503, which is relatively difficult to clear.

[0063] A crushing and recycling device including the above-mentioned water receiving components further includes a filter cylinder 11, a cylinder flange 12, and flange bolts 13. It also includes a support plate 14 disposed on the cylinder flange 12 and located above the open cylinder unit 1, a filter frame 15 disposed on the support plate 14 for settling paper fiber liquid before the squeezing and draining operation, and a single-sided filter hole 16 disposed on the side plate of the filter frame 15 for discharging the settling water b onto the inclined plate 2.

[0064] In this embodiment, the filter cylinder 11 and the two cylinder flanges 12 are integrally formed. The filter cylinder 11 can have filter holes only in its lower part, or it can have filter holes all around its circumference. The former has the advantage that the squeezed water a is less likely to spill onto the ground, while the latter has the advantage that the squeezing water operation is relatively efficient. However, it should be noted that even in the latter case, even if the water comes out from the relatively upper filter holes, it can still flow along the filter cylinder 11 and eventually fall entirely into the transverse cylinder 101.

[0065] Furthermore, the two cylindrical flanges 12 can be used to connect the paper fiber collection bin and the extrusion operation drive motor, respectively. The flange bolts 13 can be used with or without the flange nuts 19. When used together, the radial protrusion 105 also serves to prevent the loosened flange nuts 19 from falling off and being lost.

[0066] On the other hand, the support plate 14 is rectangular in shape, with its two ends respectively mounted on two cylindrical flanges 12. The single-sided filter hole 16 and the inclined plate 2 are located on the same side of the water filter cylinder 11. The filter frame 15 and the support plate 14 can be integrally formed, screwed together, or simply the former placed on the latter.

[0067] The structure of the crushing and recycling device also includes a feed inlet 17 disposed on the filter cylinder 11 and located on both sides of the filter cylinder 11, and a transverse section 18 disposed on the cylinder flange 12 and used for mounting the support plate 14.

[0068] In this embodiment, the discharge position of the above-mentioned crushing chamber is connected to the filter frame 15 or the feed inlet 17, that is, the static drainage operation is not necessary, and even if the static drainage operation is carried out, the duration can be flexibly set.

[0069] After the static drainage operation, the paper fiber liquid with a relatively low moisture content is transferred from the filter frame 15 to the feed inlet 17, and then the squeezing drainage operation can be carried out.

[0070] On the other hand, the feed inlet 17 is located relatively high and relatively close to the side of the extrusion operation drive motor, and it is equipped with a closed door, which is circular or rectangular in shape.

[0071] In addition, the main function of the transverse section 18 is to securely install the support plate 14, ensuring that the latter is horizontal, so that the still water falls onto the inclined plate 2 in a roughly horizontal manner, and is eventually collected in an orderly and comprehensive manner at the drain pipe 3.

[0072] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this application. These are non-inventive modifications and are protected by patent law as long as they are within the scope of the claims of this application.
