Description

Technical Field

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

[0002] In related technologies, seaweed foreign object sorting technology mainly employs two methods: manual and mechanical. Mechanical sorting devices utilize the principle of "grating + cleaning blade + negative pressure" for foreign object separation. This device separates seaweed material from impurities through multiple sets of grates, cleaning blades, and negative pressure suction. However, existing seaweed foreign object sorting devices have the following technical drawbacks: Wear and tear on cleaning blades and grates: Due to manufacturing precision limitations and stress during use, contact friction and wear occur between the cleaning blades and grates, leading to easy damage to the cleaning blades and increased grating gaps, thus reducing sorting efficiency. High replacement costs: Frequent replacement of cleaning blades and grates increases user costs and affects work efficiency. Limited impurity removal effect: Because the thickness of the cleaning blades cannot be too thin, the grating gap cannot be too small, affecting the impurity removal effect. Laver loss: During the process of passing through the trough, the laver material is worn and crushed by the squeezing of the cleaning blade and the trough, resulting in the loss of laver material, affecting the gloss of the laver sheets, and reducing the user's economic benefits. Trough clogging: After the machine has been working for a period of time, impurities easily accumulate in the trough, causing the cleaning blade to get stuck, requiring the machine to be stopped for manual cleaning, which is time-consuming and labor-intensive.

[0003] Therefore, it is necessary to study an efficient, durable and easy-to-maintain laver foreign object sorting device to improve laver processing efficiency and quality. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of this utility model propose a high-pressure water cleaning seam foreign object sorting device.

[0006] The high-pressure water cleaning seaweed foreign object sorting device of this utility model includes a storage box, a sorting box, a discharge pipe, a water spraying component and a driving component. The storage box has a storage cavity for placing seaweed to be sorted.

[0007] The sorting box is located inside the storage box. The sorting box has a sorting cavity and a grate is provided on the side wall of the sorting box. The grate is used for seaweed to enter the sorting cavity from the storage cavity to filter foreign objects in the seaweed material.

[0008] 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 the negative pressure pump so that the seaweed separated in the sorting chamber is discharged through the discharge pipe under the action of negative pressure.

[0009] The water spray assembly includes a hollow shaft, a water pump, and a nozzle. The hollow shaft is rotatably mounted on the sorting box and at least a portion of it is located within the sorting cavity. The water pump is connected to the hollow shaft and is used to deliver high-pressure water into the hollow shaft. The nozzle is mounted on the hollow shaft and is connected to it. The nozzle is used to spray a high-pressure water jet into the grate when the hollow shaft rotates to remove blockages in the grate. The drive assembly is connected to the hollow shaft and is used to drive the hollow shaft to rotate.

[0010] In some embodiments, the sorting box includes a plurality of grates and a plurality of washers. The grates are annular structures. The plurality of grates and the plurality of washers are arranged alternately in sequence along the height direction of the sorting box so that the grating groove is defined between two adjacent grates.

[0011] In some embodiments, the value of the grate is H, where 0.2mm ≤ H ≤ 5mm.

[0012] In some embodiments, the hollow shaft extends along the height direction of the sorting box, and there are multiple nozzles. The multiple nozzles are arranged at axial intervals along the hollow shaft, and the multiple nozzles correspond one-to-one with the multiple grates in the height direction of the sorting box.

[0013] In some embodiments, the sorting box further includes a top plate, a bottom plate, and a discharge seat cylinder. The top plate is disposed on the top layer of the grate, the discharge seat cylinder is disposed on the bottom layer of the grate and extends along the height direction of the sorting box, the bottom plate blocks the discharge seat cylinder, and the discharge pipe communicates with the discharge seat cylinder.

[0014] In some embodiments, the top plate, the grate, the discharge seat cylinder, and the bottom plate are all provided with connecting holes for the connecting rod to pass through.

[0029] 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.

[0030] like Figures 1 to 7 As shown, the high-pressure water-cleaning seaweed foreign matter sorting device 100 of this utility model embodiment includes a storage box 1, a sorting box 2, a discharge pipe 3, a water spraying assembly, and a driving assembly. The storage box 1 has a storage cavity 101 for placing seaweed 200 to be sorted. The sorting box 2 is located inside the storage box 1 and has a sorting cavity 201. A grate 202 is provided on the side wall of the sorting box 2 for the seaweed 200 to enter the sorting cavity 201 from the storage cavity 101 to filter foreign matter on the seaweed 200. One end of the discharge pipe 3 is connected to the sorting cavity 201, and the other end of the discharge pipe 3 extends out of the storage box 1 and is connected to a negative pressure pump so that the separated seaweed 200 in the sorting cavity 201 is discharged through the discharge pipe 3 under negative pressure.

[0031] The water spray assembly includes a hollow shaft 4, a water pump, and a nozzle 5. The hollow shaft 4 is rotatably mounted on the sorting box 2, with at least a portion located within the sorting chamber 201. The water pump is connected to the hollow shaft 4 and is used to deliver high-pressure water into the hollow shaft 4. The nozzle 5 is mounted on and connected to the hollow shaft 4, and is used to spray a jet of high-pressure water into the grate 202 when the hollow shaft 4 rotates, to remove blockages in the grate 202. A drive assembly is connected to the hollow shaft 4 and is used to drive the hollow shaft 4 to rotate.

[0032] In this embodiment of the high-pressure water-cleaning seaweed foreign object sorting device 100, seaweed 200 and water are mixed and stored in the storage chamber 101, forming a mixture of seaweed 200 raw material and water, ready for sorting. The discharge pipe 3 is connected to a negative pressure pump to create negative pressure in the sorting box 2. Due to the thin and smooth physical characteristics of the seaweed 200 raw material, coupled with the dilution of the aqueous solution, the seaweed 200 raw material is easily sucked into the sorting box 2 through the grate 202 under the action of negative pressure. Larger foreign objects such as nylon threads, sand, and seaweed in the seaweed 200 raw material cannot pass through the grate 202 and are filtered out, remaining in the storage chamber 101. The water pump in the water spray assembly delivers high-pressure water to the hollow shaft 4. The hollow shaft 4 rotates while spraying high-pressure water jets into the grate 202 through the nozzle 5 to clear blockages in the grate 202. The laver 200 entering the sorting box 2 is discharged through the discharge pipe 3 under the action of the negative pressure pump, thus completing the sorting process. After working for a period of time, the concentration of impurities remaining in the storage box 1 is observed, and then a small amount of residual laver 200 raw material and the retained impurities and foreign objects are discharged through the discharge port or cleaned out of the storage box 1 by manual cleaning.

[0033] The high-pressure water jet cleaning method for sorting foreign objects in seaweed according to this embodiment is a non-rigid contact cleaning method. By cleaning the grate 202 with high-pressure water jets, the cleaning blade is eliminated, avoiding direct contact and friction between the blade and the grate 202. This reduces wear on the grate 202, extends its service life, reduces component replacement frequency and maintenance costs, and improves work efficiency. Simultaneously, the seaweed experiences zero wear during passage through the grate 202, resulting in seaweed sheets with good gloss and reducing loss caused by squeezing, abrasion, and breakage from the cleaning blade and grate. Furthermore, the high-pressure water jet effectively removes tiny blockages in the small grate 202, improving impurity removal and enhancing sorting efficiency, thus reducing downtime for cleaning due to impurity blockage.

[0034] Overall, the high-pressure water cleaning seaweed foreign object sorting device 100 of this utility model optimizes the seaweed 200 foreign object sorting process by introducing high-pressure water cleaning technology, improves sorting efficiency and equipment reliability, and reduces operating costs and maintenance workload.

[0035] Optionally, the source of the mixture of seaweed 200 raw material and water in the storage tank 1 is divided into two types depending on whether the storage tank 1 is open or not. One type is an open storage tank 1, in which the seaweed 200 raw material can be drawn from the washing pool using a vegetable pump and transported into the storage tank 1 through the opening at the top or through a feeding channel provided on the side plate of the storage tank 1. The other type is a closed storage tank 1 with a door at the top, in which a feeding pipe can be provided on the side plate or door of the storage tank 1. The feeding pipe is connected to the washing pool. When the seaweed 200 material in the storage chamber 101 enters the sorting chamber 201 through the grate 202, the seaweed 200 material in the washing pool will also be continuously supplied to the storage chamber 101, maintaining the continuity of the seaweed 200 material sorting.

[0036] In some embodiments, the sorting box 2 includes a plurality of grates 203 and a plurality of washers 204. The grates 203 are annular structural members. The plurality of grates 203 and the plurality of washers 204 are arranged alternately in sequence in the height direction of the sorting box 2 so that a grating groove 202 is defined between two adjacent grates 203.

[0037] The grate 203 is a ring-shaped structural component, whose main function is to form the troughs 202 for screening seaweed 200. Gaskets 204 are located between the grate 203s and are used to adjust and maintain the gap between them, i.e., the size of the troughs 202. The grate 203s and gaskets 204 are arranged alternately along the height of the sorting box 2, thus forming several troughs 202 between adjacent grate 203s.

[0038] The combination of multiple grates 203 and washers 204 allows for more precise control of the size of the grate 202, thereby improving sorting accuracy and effectively separating foreign objects of different sizes and shapes. By replacing washers 204 of different thicknesses, the size of the grate 202 can be easily adjusted to meet the sorting needs of foreign objects of different sizes in the seaweed 200 material. When a grate 203 or washer 204 wears out, it can be replaced individually instead of the entire assembly, reducing maintenance costs and downtime.

[0039] In some embodiments, the value of the grate 202 is H, where 0.2mm ≤ H ≤ 5mm.

[0040] It should be noted that the initial sorting mainly removes larger impurities from the seaweed 200 material, such as coarse ropes, gloves, stones, and shells, requiring a gap value of 1.5mm-5mm. For the fine sorting, generally after the initial sorting and before chopping, the gap value of the grate 202 should be between 0.6mm-1.5mm. For the final sorting, under final sorting conditions, the gap value is 0.5mm-1mm when the seaweed 200 is not chopped, and 0.2mm-0.6mm after the seaweed 200 is chopped.

[0041] For example, in this embodiment of the invention, the value of the grating 202, H, is 0.2mm, 1mm, or 5mm, corresponding to fine sorting, delicate sorting, and coarse sorting. Compared with related technologies, this invention is not limited to the thickness of the cleaning blade, thus allowing the grating 202 to have a smaller value. Traditional blade-type sorting devices can only achieve a grating 202 of 0.5mm or more, while the grating 202 value H of the high-pressure water cleaning seaweed foreign matter sorting device 100 of this invention can be as small as 0.2mm, significantly improving the foreign matter sorting rate in the seaweed 200.

[0042] In some embodiments, the hollow shaft 4 extends along the height direction of the sorting box 2, and there are multiple nozzles 5. The multiple nozzles 5 are arranged at intervals along the axial direction of the hollow shaft 4, and the multiple nozzles 5 correspond one-to-one with the multiple grates 202 in the height direction of the sorting box 2.

[0043] The hollow shaft 4 extends along the height of the sorting box 2, ensuring that the nozzles 5 can cover the entire height range of the sorting box 2, thereby achieving cleaning of the grates 202 throughout the sorting process. The design of the hollow shaft 4 makes the delivery of high-pressure water more concentrated and efficient, reducing water waste. The use of multiple nozzles 5 helps improve the uniformity and efficiency of cleaning. The multiple nozzles 5 are arranged at intervals along the axial direction of the hollow shaft 4, ensuring that each grate 202 corresponds to at least one nozzle 5, ensuring the accuracy of the cleaning operation. The one-to-one correspondence between the multiple nozzles 5 and the multiple grate 202 along the height of the sorting box 2 ensures that each grate 202 is effectively cleaned, ensuring the comprehensiveness of the cleaning operation and avoiding clogging problems caused by some areas not being rinsed.

[0044] Since each grate 202 has a corresponding nozzle 5 for cleaning, the blockages inside the grate 202 can be completely removed, increasing the continuous operating time of the sorting device. The spaced arrangement of the nozzles 5 makes the cleaning more uniform, avoiding a decrease in sorting effect due to incomplete cleaning in certain areas. If it is necessary to focus on cleaning grate 202 at a specific height, the water pressure or opening time of the corresponding nozzle 5 can be adjusted accordingly, improving the flexibility of cleaning. Due to the improved cleaning efficiency, the number of downtime maintenance caused by grate 202 blockage is reduced, thereby reducing maintenance costs. The sorting device can perform the sorting of foreign objects in seaweed 200 more efficiently and stably, improving the overall operating efficiency and economic benefits.

[0045] In some embodiments, the sorting box 2 further includes a top plate 205, a bottom plate 206, and a discharge seat 207. The top plate 205 is disposed on the top grate 203, the discharge seat 207 is disposed on the bottom grate 203 and extends along the height direction of the sorting box 2, the bottom plate 206 blocks the discharge seat 207, and the discharge pipe 3 communicates with the discharge seat 207.

[0046] The top plate 205 is located on the top grate 203, and its function is to seal the top grate 203, blocking the top entry and exit of materials and ensuring the airtightness of the sorting box 2. The bottom plate 206 seals the discharge seat 207, which is located at the bottom of the sorting box 2, sealing the bottom of the sorting box 2 and serving as a support and sealing structure for the discharge seat 207. The bottom plate 206 may be designed with components for fixing and sealing to ensure the airtightness of the sorting box 2. The discharge seat 207 is located on the bottom grate 203 and extends along the height of the sorting box 2. It serves as a channel for sucking up the seaweed material 200 and conveying the separated seaweed 200 to the discharge pipe 3. The discharge seat 207 can be designed as a straight cylinder or with a certain taper to facilitate smooth material conveying and reduce blockage. The discharge pipe 3 is connected to the discharge seat cylinder 207. It serves as the channel for the seaweed 200 material to be discharged from the sorting box 2. It is connected to the negative pressure pump to realize the suction and discharge of the material.

[0047] The design of the top plate 205 and bottom plate 206 ensures that materials inside the sorting box 2 will not overflow or leak, maintaining the stability and continuity of materials within the sorting box 2. The bottom plate 206, by sealing the discharge seat 207, prevents materials from flowing out from the bottom during sorting. The sealing effect of the top plate 205 and bottom plate 206 improves the airtightness of the sorting box 2, helping to maintain internal cleanliness and reduce environmental pollution. The design of the discharge seat 207 facilitates the flow of materials during sorting, reducing the risk of material blockage and improving sorting efficiency and equipment reliability.

[0048] In some embodiments, the top plate 205, the grate 203, the discharge seat 207, and the bottom plate 206 are all provided with connecting holes for the connecting rod 6 to pass through. The top plate 205, the grate 203, the discharge seat 207, and the bottom plate 206 are connected by the connecting rod 6, and the washer 204 is sleeved on the connecting rod 6.

[0049] The top plate 205, grate 203, discharge seat 207, and bottom plate 206 are provided with connecting holes for the connecting rod 6 to pass through. The design of these holes ensures that the components can be precisely aligned and connected together. The size and position of the connecting holes need to precisely match the dimensions of the connecting rod 6 to ensure the stability of the components and the firmness of the connection. The connecting rod 6 is used to connect the top plate 205, grate 203, discharge seat 207, and bottom plate 206 into a whole, enhancing the structural strength and stability of the sorting box 2. The connecting rod 6 may be designed with threads or other locking mechanisms to facilitate the installation and disassembly of the components. A washer 204 is fitted onto the connecting rod 6, its function being to buffer the direct contact between the connecting rod 6 and the connecting holes of each component, reducing wear and providing some adjustment space. The washer 204 may be made of different materials, such as plastic, rubber, or metal, to adapt to different usage environments and requirements.

[0050] The design of the connecting rod 6 and the connecting hole makes the sorting box 2 more stable, able to withstand the mechanical forces and vibrations generated during sorting. The connection design between components allows for quick disassembly and assembly, facilitating maintenance and replacement of worn parts. The use of gasket 204 reduces direct friction between the connecting rod 6 and the connecting hole, extending the service life of the components. The adjustment space provided by gasket 204 allows for fine-tuning of component positions during installation or maintenance, ensuring precise alignment between components.

[0051] In some embodiments, a protrusion 2031 is provided on the outer wall surface of the grate 203, and a connection hole on the grate 203 is provided on the protrusion 2031.

[0052] like Figure 6 As shown, the connecting hole is set on the protrusion 2031. In this way, the connecting rod 6 will be appropriately away from the outer peripheral surface of the original grate 203, which can reduce the obstruction of the connecting rod 6 on the grate 202. That is, a larger and more complete grate 202 ring can be obtained to improve the sorting effect.

[0053] In some embodiments, the drive assembly includes a bearing housing 7, a drive motor 8, a first bevel gear 9, and a second bevel gear 10. The bearing housing 7 is disposed on a base plate 206, and a hollow shaft 4 is rotatably disposed on the bearing housing 7 with one end extending into the sorting box 2. The first bevel gear 9 is disposed at the bottom of the hollow shaft 4, and the second bevel gear 10 is disposed on the output shaft of the drive motor 8. The first bevel gear 9 meshes with the second bevel gear 10.

[0054] like Figure 2 and Figure 3 As shown, the bearing housing 7 is mounted on the base plate 206. It serves as a support structure for mounting and fixing the bearing housing 7, allowing the hollow shaft 4 to rotate on it. The bearing housing 7 needs sufficient strength and stability to ensure the smoothness and safety of the hollow shaft 4 during high-speed rotation. The drive motor 8 is the core component providing power; it drives the entire sorting device by rotating its output shaft. The drive motor 8 may have a certain protection rating to withstand possible humid or dusty environments and needs sufficient power to meet sorting requirements.

[0055] The first bevel gear 9 is located at the bottom of the hollow shaft 4 and meshes with the second bevel gear 10 to transmit power from the drive motor 8 to the hollow shaft 4. The second bevel gear 10 is located on the output shaft of the drive motor 8 and meshes with the first bevel gear 9 to complete the power transmission. The meshing of the first bevel gear 9 and the second bevel gear 10 ensures the effective transmission of power from the drive motor 8 to the hollow shaft 4. This gear meshing design allows for precise power control and speed adjustment, ensuring the normal operation of the sorting device.

[0056] The design of bearing housing 7 ensures stable rotation of hollow shaft 4, reducing vibration and noise. Precise drive of hollow shaft 4 is achieved through bevel gear meshing, guaranteeing efficiency in the sorting process. Compared to direct connection or other transmission methods, bevel gear transmission offers higher reliability and durability over long-term operation. The bevel gear design allows for individual gear replacement without replacing the entire drive assembly, reducing maintenance costs. This drive assembly design allows for adjustment of speed and torque by changing bevel gears with different parameters to meet varying sorting needs.

[0057] In some embodiments, a sealing ring or sealant is provided between the bearing housing 7 and the base plate 206.

[0058] Sealing rings or sealant are used to seal the gap between the bearing housing 7 and the base plate 206, preventing grease leakage and the ingress of foreign matter such as dust. In these embodiments, the sealing effect between the bearing housing 7 and the base plate 206 is improved, effectively preventing grease leakage and the intrusion of foreign matter such as dust, thereby improving the service life of the bearing and the overall reliability of the sorting device.

[0059] In some embodiments, the water spray assembly further includes a rotary joint 11, which includes a central cylinder 1101 and a first flange 1102 and a second flange 1103 disposed at both ends of the central cylinder 1101. The first flange 1102 is rotatably connected to the central cylinder 1101 and is connected to the hollow shaft 4. The second flange 1103 is connected to a water pump so that high-pressure water output by the water pump is delivered to the hollow shaft 4 through the rotary joint 11.

[0060] The central cylinder 1101 is the main body of the rotary joint 11, used for connecting and conveying high-pressure water. The first flange 110 is located at one end of the central cylinder 1101 and is rotatably connected to it, used for connecting to the hollow shaft 4. The second flange 1103 is located at the other end of the central cylinder 1101 and is connected to the water pump, used to receive the high-pressure water output from the pump. The first flange 1102 is connected to the hollow shaft 4, allowing high-pressure water to be continuously conveyed into the hollow shaft 4 through the rotary joint 11 while the hollow shaft 4 is rotating. The high-pressure water output from the pump enters the central cylinder 1101 through the second flange 1103, then is conveyed to the hollow shaft 4 through the rotary joint 11, and finally reaches the nozzle 5 for spraying.

[0061] The use of rotary joint 11 ensures that the supply of high-pressure water is uninterrupted during the rotation of hollow shaft 4, thus guaranteeing the continuity and effectiveness of the cleaning process. The sealing design of rotary joint 11 reduces high-pressure water leakage at the connection point, improving the system's sealing performance. The design of rotary joint 11 reduces equipment failures caused by interruptions or leaks in the high-pressure water supply, improving the reliability of the entire sorting device. The structural design of rotary joint 11 makes maintenance and replacement more convenient, reducing maintenance costs and time.
