Description

Technical Field

[0001] This utility model relates to the technical field of laver screening equipment, specifically to a laver foreign object sorting and cleaning device. Background Technology

[0002] In related technologies, seaweed material is separated from foreign objects through a sorting box. Specifically, the side wall of the sorting box has a grate. When the seaweed material to be sorted is placed outside the sorting box, a negative pressure is created inside. Due to its slippery physical properties, seaweed easily passes through the grate under the negative pressure. However, impurities and foreign objects mixed in with the seaweed material, such as nylon threads, sand, and seaweed, whose individual volume exceeds the width of the grate, cannot pass through the grate and are filtered out, thus completing the sorting process. However, because seaweed is long and thin, it easily adheres to the side wall of the sorting box and clogs the grate, preventing seaweed from passing through smoothly and reducing the sorting flow. At the same time, when the concentration of impurities and foreign objects blocked outside the sorting box increases to a certain level, the machine needs to be stopped for manual cleaning, which is time-consuming and labor-intensive, reducing sorting efficiency. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a planetary cleaning and impurity removal device for sorting foreign objects in seaweed.

[0005] The laver foreign object sorting and planetary cleaning device of this utility model includes a storage box, a sorting box, a planetary gear assembly, a drive assembly, and a cleaning roller assembly. The storage box is used to hold laver to be sorted. The sorting box is located inside the storage box, and multiple grates are formed on the side wall of the sorting box. The multiple grates are arranged at intervals along the height direction of the sorting box. The grates are used to filter foreign objects from the laver by allowing it to enter the sorting box under negative pressure. The planetary gear assembly includes a sun gear, planetary gears, and a planetary gear assembly. The system includes a gear and a planetary carrier. The sun gear is fixed to the top of the sorting box, and the planetary carrier is rotatably connected to the sun gear. The planetary gear is rotatably mounted on the planetary carrier and meshes with the sun gear. The drive assembly is used to drive the planetary carrier to rotate, so that the planetary gears rotate and revolve. The cleaning roller assembly is mounted on the planetary gears, so that the planetary gears drive the cleaning roller assembly to rotate and revolve, thereby removing laver from the outer periphery of the sorting box or removing and removing foreign objects from the laver.

[0006] In some embodiments, the cleaning roller assembly includes a first cleaning roller assembly, which includes a first rotating shaft and a plurality of rejection discs. The first rotating shaft is coaxially connected to the planetary gear, and the rejection discs are fitted onto the first rotating shaft. An annular groove is formed on the outer wall of the sorting box, the annular groove being located between two adjacent grates and arranged around the circumference of the sorting box. The plurality of rejection discs correspond one-to-one with the plurality of annular grooves, and at least a portion of each rejection disc is located within the annular groove; and / or

[0007] The cleaning roller assembly further includes a second cleaning roller assembly, which includes a second rotating shaft, a brush cylinder, and brush bristles. The second rotating shaft is coaxially connected to the planetary gear, the brush cylinder is fitted on the second rotating shaft, and the brush bristles are disposed on the outer peripheral surface of the brush cylinder.

[0008] In some embodiments, the first cleaning roller assembly further includes a plurality of spacers, which are arranged alternately with the plurality of scraping discs along the axial direction of the first rotating shaft.

[0009] In some embodiments, the outer peripheral surface of the scraping disc is provided with scraping teeth, each scraping tooth having a first cutting edge and a second cutting edge, the first cutting edge and the second cutting edge being arranged opposite to each other along the rotation direction of the scraping disc.

[0010] In some embodiments, the number of planetary gears is multiple and they are centrally symmetrically distributed about the sun gear.

[0011] In some embodiments, the first cleaning roller assembly and the second cleaning roller assembly are arranged alternately along the circumference of the sun gear.

[0012] In some embodiments, the drive assembly includes a drive shaft and a drive motor. The drive shaft is rotatably mounted on the sorting box and extends through the sorting box along its height direction. The top end of the drive shaft is fixedly connected to the planetary carrier. The sun gear is sleeved on the drive shaft. The drive motor is connected to the bottom end of the drive shaft to drive the drive shaft to rotate.

[0013] In some embodiments, the drive shaft is a hollow shaft, and a nozzle communicating with the hollow shaft is provided on the hollow shaft. The nozzle is used to spray high-pressure water jets into the grate.

[0014] The laver foreign object sorting planetary cleaning and impurity removal device also includes a rotary joint, which includes a central cylinder and a first flange and a second flange disposed at both ends of the central cylinder. The first flange is rotatably connected to the central cylinder and is connected to the hollow shaft. The second flange is used to communicate with a water pump so that the water pump delivers high-pressure water into the hollow shaft.

[0015] In some embodiments, the drive assembly further includes a first bevel gear and a second bevel gear, the first bevel gear being disposed at the bottom of the hollow shaft and the second bevel gear being disposed on the output shaft of the drive motor, the first bevel gear meshing with the second bevel gear.

[0016] In some embodiments, the laver foreign matter sorting and cleaning device of this utility model further includes a discharge pipe. One end of the discharge pipe is connected to the sorting chamber, and the other end of the discharge pipe extends out of the storage box and is used to connect to a negative pressure pump so that the laver separated in the sorting box is discharged through the discharge pipe under the action of negative pressure.

[0017] In use, the laver foreign object sorting and planetary cleaning device of this utility model allows the laver raw material to be easily sucked into the sorting box through the grate under negative pressure. Larger foreign objects such as nylon threads, sand, and seaweed mixed in with the laver cannot pass through the grate and are filtered out, remaining in the storage box, thus completing the sorting process of foreign objects in the laver. During the suction and sorting process, the drive component drives the planetary frame to rotate. Under the action of the sun gear, the planetary gears revolve around the sun gear and also rotate on their own axes. The planetary gears drive the cleaning roller assembly to rotate on its own axis and revolve around the sun. The removal discs within the cleaning roller assembly cut long seaweed adhering to the outer wall of the sorting box, remove foreign objects from the seaweed material, or utilize the entanglement and separation properties of the brush cylinders in the cleaning roller assembly to entangle and separate linear foreign objects such as nylon filaments from broken seaweed. This prevents the seaweed or foreign objects in the seaweed material from clogging the grate on the outer wall of the sorting box, thus avoiding a reduction in sorting flow. Simultaneously, the continuous entanglement and separation of linear foreign objects from broken seaweed significantly improves sorting efficiency. Furthermore, it reduces the frequency of manual cleaning of clogged grate channels, lowers labor intensity and labor costs, and reduces downtime caused by clogged channels, thereby further improving sorting efficiency.

[0030] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] like Figures 1 to 10 As shown, the laver foreign object sorting and planetary cleaning device 100 of this utility model includes a storage box 1, a sorting box 2, a planetary gear assembly, a drive assembly, and a cleaning roller assembly. The storage box 1 is used to hold laver 200 to be sorted. The sorting box 2 is located inside the storage box 1. Multiple grates 201 are provided on the side wall of the sorting box 2, and the multiple grates 201 are arranged at intervals in the height direction of the sorting box 2. The grates 201 are used to filter foreign objects in the laver 200 from the storage box 1 into the sorting box 2 under negative pressure.

[0032] The planetary gear assembly includes a sun gear 3, planetary gears 4, and a planet carrier 5. The sun gear 3 is fixed to the top of the sorting box 2. The planet carrier 5 is rotatably connected to the sun gear 3. The planetary gear 4 is rotatably mounted on the planet carrier 5 and meshes with the sun gear 3. A drive assembly is used to drive the planet carrier 5 to rotate, so that the planetary gear 4 rotates and revolves. A cleaning roller assembly is mounted on the planetary gear 4, so that the planetary gear 4 drives the cleaning roller assembly to rotate and revolve, thereby removing laver 200 from the outer peripheral wall of the sorting box 2 or removing and removing foreign objects from the laver 200.

[0033] In use, the laver foreign matter sorting and cleaning device 100 of this utility model involves placing the laver 200 to be sorted in the storage box 1 and mixing it with water to form a mixture of laver 200 raw material and water, ready for sorting. Due to the thin and smooth physical properties of the laver 200 raw material, coupled with the dilution of the aqueous solution, the laver 200 raw material is easily sucked into the sorting box 2 through the grate 201 under negative pressure. Larger foreign matter such as nylon threads, sand, and seaweed mixed in the laver 200 cannot pass through the grate 201 and is filtered out, remaining in the storage box 1, thus completing the sorting process of foreign matter in the laver 200.

[0034] During the suction and sorting process of laver 200, the drive assembly drives the planetary frame 5 to rotate. Under the action of the sun gear 3, the planetary gear 4 revolves around the sun gear 3 while also rotating on its own axis. The planetary gear 4 then drives the cleaning roller assembly to rotate on its own axis and revolve around the sun gear 3. The cleaning roller assembly then removes or separates linear foreign objects adsorbed on the outer wall of the sorting box 2, preventing the laver 200 or foreign objects in the laver 200 from clogging the grate 201 and reducing the sorting flow rate. At the same time, by continuously entangled and separated linear foreign objects in the laver 200, the impurity concentration in the laver 200 is reduced, greatly improving sorting efficiency. This also reduces the frequency of manual cleaning of the grate 201, reducing labor intensity and labor costs, and minimizing downtime caused by clogged grate 201, thereby further improving sorting efficiency.

[0035] In some embodiments, the cleaning roller assembly includes a first cleaning roller assembly 6, which includes a first rotating shaft 601 and a plurality of rejection discs 602. The first rotating shaft 601 is coaxially connected to the planetary gear 4, and the rejection discs 602 are fitted onto the first rotating shaft 601. An annular groove 202 is provided on the outer wall of the sorting box 2. The annular groove 202 is located between two adjacent grates 201 and is arranged around the sorting box 2. The plurality of rejection discs 602 correspond one-to-one with the plurality of annular grooves 202, and at least a portion of the rejection discs 602 is located within the annular grooves 202.

[0036] It should be noted that, as Figures 3 to 7 As shown, the first cleaning roller assembly 6 is typically used for sorting elongated seaweed 200. Specifically, when the first cleaning roller assembly 6 is in use, since at least a portion of the scraping disc 602 is located within the annular groove 202, as the scraping disc 602 rotates and revolves, it cuts or removes foreign objects from the elongated seaweed 200 adhering to the outer peripheral wall of the sorting box 2. The cut seaweed 200 passes more easily through the grate 201, and the removal of seaweed 200 or foreign objects keeps the grate 201 unobstructed and reduces the chance of foreign objects entering the grate 201, further improving sorting efficiency.

[0037] In some embodiments, the cleaning roller assembly further includes a second cleaning roller assembly 7, which includes a second rotating shaft 701, a brush cylinder 702, and brush bristles 703. The second rotating shaft 701 is coaxially connected to the planetary gear 4, the brush cylinder 702 is mounted on the second rotating shaft 701, and the brush bristles 703 are disposed on the outer peripheral surface of the brush cylinder 702.

[0038] It should be noted that, as Figures 8 to 10 As shown, the function of the second cleaning roller assembly 7 is to use the brush cylinder 702 and brush bristles 703 to entangle and separate foreign objects in the seaweed 200 material during its rotation and revolution, preventing a rapid increase in the concentration of impurities in the seaweed 200 material outside the sorting box 2. When enough impurities are entangled on the brush cylinder 702 and brush bristles 703, only a short stop is needed to replace the brush cylinder 702 before continuing operation, improving work efficiency. In addition, the lower impurity concentration after the foreign objects are promptly entangled by the brush cylinder 702 is beneficial to improving the sorting rate of foreign objects in the seaweed 200.

[0039] Of course, the first cleaning roller assembly 6 is mainly used for sorting long strips of seaweed 200, and the second cleaning roller assembly 7 is mainly used for sorting foreign objects from chopped seaweed 200. The first cleaning roller assembly 6 and the second cleaning roller assembly 7 can also be used in combination.

[0040] In some embodiments, the first cleaning roller assembly 6 further includes a plurality of spacers 603, which are arranged alternately with a plurality of scraping discs 602 along the axial direction of the first rotating shaft 601.

[0041] like Figure 3 and Figure 6 As shown, the spacer 603 is a spacer whose main function is to provide support for the shaving disc 602 on the first rotating shaft 601 and to maintain their relative position. The design of the spacer 603 ensures that the shaving disc can be accurately installed in the predetermined position, which helps to improve the assembly efficiency of the first cleaning roller assembly 6.

[0042] In some embodiments, the outer peripheral surface of the scraping disc 602 is provided with scraping teeth 604, the scraping teeth 604 having a first cutting edge 6041 and a second cutting edge 6042, the first cutting edge 6041 and the second cutting edge 6042 being arranged opposite to each other along the rotation direction of the scraping disc 602.

[0043] like Figure 7 As shown, when the strip of seaweed 200 and foreign objects attached to the outer wall of the sorting box 2 are picked away by the picker 602, the seaweed 200 may be cut by the first blade 6041 and the second blade 6042 to increase the passability of the seaweed 200 and further improve the cleaning efficiency.

[0044] In some embodiments, the number of planetary gears 4 is multiple and they are centrally symmetrically distributed about the sun gear 3.

[0045] There are multiple planetary gears 4, and they are centrally symmetrically distributed about the sun gear 3. This distribution ensures the balance of the planetary gear 4 assembly and reduces mechanical vibration caused by uneven gear distribution. The central symmetry helps improve the balance of the planetary gear 4 assembly during rotation, thereby reducing operating noise and wear, and extending the service life of the equipment. When multiple planetary gears 4 work simultaneously, they can work together to complete the cleaning task, improving cleaning efficiency and sorting quality.

[0046] In some embodiments, the first cleaning roller assembly 6 and the second cleaning roller assembly 7 are arranged alternately along the circumference of the sun gear 3.

[0047] The first cleaning roller assembly 6 and the second cleaning roller assembly 7 are arranged alternately along the circumference of the sun gear 3. This arrangement can achieve a uniform distribution between the scraping disc 602 and the brush cylinder 702, thereby providing a uniform cleaning effect on the outer wall surface of the sorting box 2 to improve cleaning efficiency.

[0048] Optionally, such as Figure 1 and Figure 2 As shown, the drive assembly includes a drive shaft 8 and a drive motor 9. The drive shaft 8 is rotatably mounted on the sorting box 2 and passes through the sorting box 2 along the height direction of the sorting box 2. The top end of the drive shaft 8 is fixedly connected to the planetary carrier 5. The sun gear 3 is sleeved on the drive shaft 8. The drive motor 9 is connected to the bottom end of the drive shaft 8 to drive the drive shaft 8 to rotate.

[0049] In some embodiments, the drive shaft 8 is a hollow shaft, and a nozzle 10 communicating with the hollow shaft is provided on the hollow shaft. The nozzle 10 is used to spray high-pressure water jets into the grate 201.

[0050] The laver foreign object sorting and cleaning device 100 of this utility model also includes an adapter. The rotary adapter 11 includes a central cylinder 1101 and a first flange 1102 and a second flange located at both ends of the central cylinder 1101. The first flange 1102 is rotatably connected to the central cylinder 1101 and is connected to a hollow shaft. The second flange is used to communicate with a water pump so that the water pump can deliver high-pressure water into the hollow shaft.

[0051] The drive shaft 8 is designed as a hollow shaft to allow for the delivery of high-pressure water inside. A nozzle 10, communicating with the hollow shaft and located near the grate 201, is used to spray high-pressure water jets into the grate 201 to remove seaweed 200 residue and other impurities that may clog it. The rotary joint 11 includes a central cylinder 1101, which connects to and transmits the high-pressure water. A first flange 1102 is rotatably connected to the central cylinder 1101 and to the hollow shaft, ensuring that the high-pressure water delivery is not affected during rotation. A second flange connects to a water pump, allowing the pump to deliver high-pressure water into the hollow shaft to supply water to the nozzle 10.

[0052] High-pressure water jet cleaning can quickly remove blockages from the grate 201, improving cleaning efficiency and reducing downtime. Automated high-pressure water jet cleaning reduces the frequency and difficulty of manual cleaning. More thorough cleaning helps ensure the quality of the sorted seaweed 200, reducing the possibility of impurities contaminating. Regular high-pressure water jet cleaning helps reduce wear on the grate 201 and other components, extending the equipment's lifespan.

[0053] In some embodiments, the drive assembly further includes a first bevel gear 12 and a second bevel gear 13. The first bevel gear 12 is disposed at the bottom of the hollow shaft, and the second bevel gear 13 is disposed on the output shaft of the drive motor 9. The first bevel gear 12 meshes with the second bevel gear 13.

[0054] like Figure 1 As shown, the second bevel gear 13 is mounted on the output shaft of the drive motor 9. It meshes with the first bevel gear 12, transmitting the motor's power to the first bevel gear 12. The first bevel gear 12, located at the bottom of the hollow shaft, receives power from the second bevel gear 13 and transmits it to the planetary gear 4 assembly via the hollow shaft. The bevel gear meshing transmission method offers high transmission efficiency and effectively reduces energy loss. Bevel gears can adapt to connections on different axes, making the design more flexible and adaptable to various layouts and space constraints. The bevel gear meshing design helps reduce vibration and noise during transmission, improving the operational stability of the device. The bevel gear design can withstand large torques, ensuring stable power transmission from the motor to the planetary gear 4 assembly.

[0055] In some embodiments, such as Figure 1 and Figure 2 As shown, the laver foreign object sorting and cleaning device 100 of this utility model also includes a discharge pipe 14. One end of the discharge pipe 14 is connected to the sorting chamber, and the other end of the discharge pipe 14 extends out of the storage box 1 and is used to connect to the negative pressure pump so that the laver 200 separated in the sorting box 2 is discharged through the discharge pipe 14 under the action of negative pressure.

[0056] Under negative pressure, the separated seaweed 200 in sorting box 2 can be extracted through discharge pipe 14, effectively removing the seaweed 200 from sorting box 2 while maintaining the continuity of the sorting process. The design of discharge pipe 14 allows the seaweed 200 to be discharged from sorting box 2 quickly and continuously, improving sorting efficiency. Automatic discharge of seaweed 200 via a negative pressure pump reduces the need for manual intervention and lowers labor intensity. The design of discharge pipe 14 also helps maintain a clean working environment, as the seaweed 200 can be directly extracted to a designated location, reducing dust and pollution during the sorting process.
