Description

Technical Field

[0001] This utility model relates to the technical field of pulp processing equipment, specifically to a recycled pulp fiber separation device. Background Technology

[0002] In the paper industry, the production of recycled paper is of great significance for resource conservation and environmental protection. Recycled pulp fiber separation is a crucial step in recycled paper production, and its effectiveness directly affects the quality and production cost of recycled paper. An existing patent, CN219586456U, describes a pulp fiber separation device. It includes a base with a threaded support at its upper end. One end of the support has a fixing hole, and the other end of the fixing hole houses the separation body. This invention utilizes a drive motor, a stirring rod, and a collection assembly. The drive motor rotates the stirring rod, generating centrifugal force that rapidly rotates the pulp fibers. As the pulp passes through a fiber filter, the fibers are blocked and separated, facilitating rapid pulp separation. The drive motor, stirring rod, and cleaning assembly allow a scraper to contact the inner wall of the separation body. After use, the drive motor cleans the inner wall, maintaining its smoothness and improving the device's cleanliness.

[0003] Regarding the aforementioned technologies, the inventors believe that the following shortcomings exist: Existing recycled pulp fiber separation devices have many deficiencies. Some devices have low separation efficiency, resulting in long production cycles and limited output. Furthermore, after separation, certain fiber impurities inevitably adhere to the interior of the separation structure. If not cleaned in time, these impurities can easily deteriorate, affecting subsequent use. Therefore, we propose a recycled pulp fiber separation device to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a recycled pulp fiber separation device, including a separation box, wherein a screen cylinder mechanism with an internal hollow structure is fixedly connected inside the separation box, the screen cylinder mechanism is used for pulp fiber separation, and the screen cylinder mechanism has a screen hole assembly arranged in a ring array inside;

Beneficial effects

[0013] This invention provides a recycled pulp fiber separation device. Compared with the prior art, it has the following advantages:

[0014] This recycled pulp fiber separation device uses a servo motor to drive the transmission shaft, which in turn rotates the spiral separation component to assist in the separation of pulp fibers within the screen cylinder mechanism. This design allows the fibers to be subjected to more effective forces during the separation process, accelerating the separation speed, improving separation efficiency, shortening the production cycle, and increasing output.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6This utility model provides a technical solution: a recycled pulp fiber separation device, including a separation box 1, a screen cylinder mechanism 3 with an internal hollow structure is fixedly connected inside the separation box 1, the screen cylinder mechanism 3 is used for pulp fiber separation, and the screen cylinder mechanism 3 has a screen hole assembly 301 arranged in a ring array inside the screen cylinder mechanism 3.

[0025] A servo motor 3011 is fixedly connected to the left end face of the separation box 1. A transmission shaft 3012 is mounted on the right output shaft of the servo motor 3011 via a coupling. A longitudinally arranged mounting base 3013 is fixedly connected to the inner side of the screen cylinder mechanism 3. The transmission shaft 3012 is rotatably connected to the mounting base 3013 via a bearing seat. A spiral separation component 3014 is fixedly connected to the outer side of the transmission shaft 3012.

[0026] The pulp fibers are separated through the screen cylinder mechanism 3 inside the separation chamber 1 via the screen hole assembly 301. The servo motor 3011 drives the transmission shaft 3012 to rotate, which in turn drives the separation assembly 3014 to rotate. The force generated by the spiral structure can be used to assist in the separation of pulp fibers, so that the fibers can be better separated from other substances and the separation efficiency can be improved.

[0027] See Figures 1-5 A hopper assembly 3015 is fixedly connected to the outer circumferential surface of the screen cylinder mechanism 3. The hopper assembly 3015 is a frustoconical structure that is thicker at the top and thinner at the bottom, and it is connected to the screen cylinder mechanism 3.

[0028] The hopper assembly 3015 on the outer periphery of the screen cylinder mechanism 3 is a truncated cone shape with a thicker top and a thinner bottom, and it is connected to the screen cylinder mechanism 3. This structural design facilitates the concentration of pulp and its smooth entry into the screen cylinder mechanism 3, which helps to improve the pulp feeding efficiency and ensure the continuity of the separation process.

[0029] See Figures 3-4 A hollow structure bracket assembly 101 is fixedly connected to the bottom end face of the separation box 1. There are two bracket assemblies 101, which are fixedly connected to the left and right sides of the bottom end face of the separation box 1 respectively.

[0030] There are two hollow support components 101 at the bottom of the separation box 1, located on the left and right sides of the bottom end face of the separation box 1 respectively. The hollow design can reduce the weight of the device and provide good support, ensuring that the separation box 1 is placed stably and ensuring the stability of the device during operation.

[0031] See Figures 2-5 A through hole is provided on the left side of the separation box 1, and a drain pipe 1011 is fixedly connected inside the through hole. The drain pipe 1011 is used to discharge waste liquid from inside the separation box 1.

[0032] The waste liquid in the separation tank 1 can be discharged in time through the drain pipe 1011 on the left side of the separation tank 1, so as to avoid the waste liquid from accumulating in the tank and affecting the separation effect. At the same time, it is also conducive to keeping the inside of the device clean and reducing the interference of impurities on subsequent separation work.

[0033] See Figures 1-2 The rear side of the separation box 1 is fixedly connected to a support mechanism 2, which is an L-shaped structure and has two locations.

[0034] The two L-shaped support mechanisms 2 on the rear side of the separation box 1 can provide stable support from the rear. Together with the support assembly 101 at the bottom, they enhance the overall stability of the device and prevent the separation box 1 from shaking or tipping over during operation.

[0035] See Figures 5-6 Two support mechanisms 2 are fixedly connected in a linear array to the left and right sides of the rear end face of the separation box 1, and a current collection component 201 is also fixedly connected to the front end face of the two support mechanisms 2.

[0036] Through the collection components 201 on the front face of the two support mechanisms 2, in conjunction with the liquid inlet pipe 2011, the liquid inlet flange 2012 and the nozzle assembly 2013, the cleaning fluid and other liquids that enter through the liquid inlet flange 2012 can be collected by the liquid inlet pipe 2011 into the collection components 201 and then sprayed out by the nozzle assembly 2013, which facilitates the cleaning of the internal components such as the screen cylinder mechanism 3.

[0037] See Figures 1-4 The flow collector 201 has an internal hollow structure, and an inlet pipe 2011 that communicates with it is fixedly connected to the top surface of the flow collector 201. An inlet flange 2012 is fixedly connected to the top of the inlet pipe 2011, and a nozzle assembly 2013 is fixedly connected in a straight array on the bottom surface of the flow collector 201.

[0038] Through the structure of the manifold assembly 201 and its connection with the liquid inlet pipe 2011, the liquid inlet flange 2012, and the nozzle assembly 2013, the liquid can be centrally introduced, collected, and uniformly sprayed out, which facilitates the cleaning of the internal components of the device and helps to clean the fiber impurities attached to the separation structure in a timely manner, avoiding the deterioration of impurities and affecting subsequent use.

[0039] During operation, first, move the recycled pulp fiber separation device to a suitable work site, ensuring that the hollow support components 101 on the left and right sides of the bottom of the separation box 1 are placed stably on the ground. At the same time, the L-shaped support mechanisms 2 on the left and right sides of the rear side also firmly support the separation box 1, keeping the entire device stable and providing a solid foundation for subsequent separation operations. Check whether the connections of each component of the device are firm, especially the fixing of the screen cylinder mechanism 3 to the separation box 1, the connection of the servo motor 3011 to the separation box 1, and the assembly of the drive shaft 3012 with the servo motor 3011 and the mounting base 3013, etc., to ensure that there is no looseness. After confirming that everything is correct, connect the liquid inlet flange 2012 to the external cleaning fluid supply system for subsequent cleaning device use.

[0040] The recycled pulp to be separated is placed above the hopper assembly 3015. Under the action of gravity, the pulp slides down the truncated cone-shaped inner wall of the hopper assembly 3015, which is thicker at the top and thinner at the bottom. Since the hopper assembly 3015 is connected to the screen cylinder mechanism 3, the pulp smoothly enters the screen cylinder mechanism 3. The special structural design of the hopper assembly 3015 not only facilitates the concentrated feeding of pulp, but also enables the pulp to be initially dispersed when entering the screen cylinder mechanism 3, creating favorable conditions for subsequent fiber separation.

[0041] When the power is turned on, the servo motor 3011 mounted on the left end face of the separation box 1 starts running. The right output shaft of the servo motor 3011 drives the transmission shaft 3012 to rotate at high speed via a coupling. The mounting seat 3013, which is longitudinally arranged inside the screen cylinder mechanism 3, provides stable rotational support for the transmission shaft 3012 through its internal bearing seat, ensuring that the transmission shaft 3012 will not deviate or wobble during rotation. As the transmission shaft 3012 rotates, the spiral structure separation component 3014 fixed on its outer side rotates synchronously. The spiral structure of the separation component 3014 generates a spiral force when rotating. A force drives the pulp inside the screen cylinder mechanism 3 to move along the axial direction of the screen cylinder mechanism 3. During the movement of the pulp, the screen hole assembly 301 distributed in a ring array inside the screen cylinder mechanism 3 plays a screening role. Fibers and liquids smaller than the screen holes of the screen hole assembly 301 are separated through the screen holes under the action of pulp flow pressure and spiral force and enter the space outside the screen cylinder mechanism 3 in the separation box 1. Fibers larger than the screen holes remain in the screen cylinder mechanism 3 and continue to be separated until they meet the requirements and pass through the screen holes or are discharged from the right outlet of the screen cylinder mechanism 3, thereby achieving efficient separation of pulp fibers from other substances.

[0042] During the fiber separation process, the separated waste liquid will gradually accumulate in the separation tank 1. In order to ensure that the separation effect is not affected, the drain pipe 1011 installed in the through hole on the left side of the separation tank 1 plays a role. Under the action of gravity and the pressure inside the separation tank 1, the waste liquid is discharged from the separation tank 1 through the drain pipe 1011, so that the separation tank 1 always maintains a good separation environment, avoids excessive accumulation of waste liquid from interfering with fiber separation, and ensures the continuous and stable operation of the separation process.

[0043] After the device has been used for a period of time, in order to prevent the fiber impurities attached to the internal components such as the screen cylinder mechanism 3 from deteriorating and affecting subsequent use, the device needs to be cleaned. The external cleaning fluid supply system is turned on, and the cleaning fluid is introduced through the inlet flange 2012 and flows into the hollow collection component 201 along the inlet pipe 2011. After collecting the cleaning fluid, the collection component 201 sprays the cleaning fluid evenly onto the internal components such as the screen cylinder mechanism 3 at a certain pressure and angle through the spray nozzle assembly 2013, which is fixedly connected in a straight array on its bottom end face. The layout and spray angle design of the spray nozzle assembly 2013 ensure that the cleaning fluid can cover all parts of the screen cylinder mechanism 3, effectively remove the attached fiber impurities, keep the device clean, and prepare for the next separation operation.

[0044] In summary, this device, through the sieve cylinder mechanism 3, can achieve rapid separation of water from fibers.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
