Description

Technical Field

[0001] The invention relates to the technical field of laver screening equipment, and in particular to a high-pressure water seam-cleaning laver foreign matter sorting device. Background Art

[0002] In the related art, there are two main methods for laver foreign body sorting technology: manual and mechanical. The mechanical sorting device uses the principle of "grate + cleaning knife + negative pressure" to separate foreign matter. This device separates laver materials from impurities by means of multiple sets of grate grooves, cleaning knives and negative pressure suction. However, the existing laver foreign body sorting device has the following technical defects: Wear problems of cleaning knives and grate grooves: Due to the limitations of manufacturing precision and the influence of forces during use, contact friction and wear will occur between the cleaning knife and the grate groove, resulting in the cleaning knife being easy to wear and the grate groove gap increasing, thereby reducing the sorting effect. High replacement cost: Frequent replacement of cleaning knives and grates increases the user's use cost and affects work efficiency. Limited impurity removal effect: Since the thickness of the cleaning knife cannot be too thin, the slot gap value cannot be too small, which affects the impurity removal effect. Laver loss problem: The laver material is squeezed and ground by the cleaning knife and the grate when passing through the grate, causing the loss of laver material, affecting the glossiness of the laver sheets and reducing the economic benefits of users. Slot congestion problem: After the machine has been working for a period of time, impurities are easily accumulated in the slot, causing the cleaning knife to be clamped, requiring the machine to be stopped for manual cleaning, which is time-consuming and labor-intensive.

DETAILED DESCRIPTION

[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figures 1 to 7 As shown, the high-pressure water-cleaned seam-type laver foreign body sorting device 100 of the embodiment of the present invention comprises a storage box 1, a sorting box 2, a discharge pipe 3, a water spray assembly and a driving assembly. The storage box 1 has a storage cavity 101, and the storage cavity 101 is used to place the laver 200 to be sorted. The sorting box 2 is arranged in the storage box 1, and the sorting box 2 has a sorting cavity 201. A grate groove 202 is provided on the side wall of the sorting box 2, and the grate groove 202 is used for the laver 200 to enter the sorting cavity 201 from the storage cavity 101 to filter foreign bodies on the laver 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 used to be connected to a negative pressure pump, so that the laver 200 separated in the sorting cavity 201 is discharged through the discharge pipe 3 under the action of negative pressure.

[0031] The water spray assembly includes a hollow shaft 4, a water pump and a spray head 5. The hollow shaft 4 is rotatably disposed on the sorting box 2 and at least a portion of the hollow shaft 4 is located in 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 spray head 5 is disposed on the hollow shaft 4 and is connected to the hollow shaft 4. The spray head 5 is used to spray a high-pressure water jet to the grate groove 202 when the hollow shaft 4 rotates, so as to remove the blockage in the grate groove 202. The driving assembly is connected to the hollow shaft 4 and is used to drive the hollow shaft 4 to rotate.

[0032] When the high-pressure water-cleaning seam-type laver foreign body sorting device 100 of the embodiment of the present invention is used, the laver 200 and water are mixed and stored in the storage chamber 101 to form a mixture of the laver 200 raw material and water, ready for sorting. The discharge pipe 3 is connected to the negative pressure pump to form a negative pressure in the sorting box 2. 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 can be easily sucked into the sorting box 2 through the grate groove 202 under the action of negative pressure, while the larger foreign bodies such as nylon thread, sand and gravel, and water grass in the laver 200 raw material cannot pass through the grate groove 202 and are filtered out and remain in the storage chamber 101. The water pump in the water spray assembly delivers high-pressure water to the hollow shaft 4, and the hollow shaft 4 rotates while spraying a high-pressure water jet to the grate groove 202 through the nozzle 5 to clean the blockage in the grate groove 202. The laver 200 entering the sorting box 2 is discharged through the discharge pipe 3 under the action of the negative pressure pump, thereby completing the sorting process. After working for a period of time, the concentration of impurities retained in the storage box 1 is observed, and then a small amount of residual laver 200 raw materials and retained impurities and foreign objects are discharged or cleaned out of the storage box 1 through the impurity discharge port by manual cleaning.

[0033] The high-pressure water seam cleaning laver foreign body sorting device 100 of the embodiment of the present invention belongs to non-rigid contact seam cleaning, and the grate groove 202 is cleaned by high-pressure water jet, and the cleaning knife component is eliminated, and the direct contact and friction between the cleaning knife and the grate groove 202 are avoided, thereby reducing the wear on the grate groove 202, and the service life of the grate groove 202 is extended, the replacement frequency and maintenance cost of components are reduced, and the work efficiency is improved. At the same time, the laver is zero-wear in the process of passing through the grate groove 202, not only the processed laver 200 sheets have good glossiness, but also the loss of laver 200 caused by the extrusion wear and grinding of the cleaning knife and the grate groove is reduced. In addition, the high-pressure water jet can effectively remove the tiny blockages in the tiny grate groove 202, improve the impurity removal effect, and then enhance the sorting effect, and reduce the downtime cleaning time caused by impurity congestion.

[0034] In general, the high-pressure water seam cleaning type laver foreign matter sorting device 100 of the embodiment of the present invention optimizes the laver 200 foreign matter sorting process by introducing high-pressure water seam cleaning technology, improves sorting efficiency and equipment reliability, and reduces operating costs and maintenance workload.

[0035] Optionally, the source of the mixture of the laver 200 raw material and water in the storage box 1 is divided into two types according to whether the storage box 1 is open. One is an open storage box 1, which can use a vegetable pump to extract the laver 200 raw material from the vegetable washing pool and transport the laver 200 raw material into the storage box 1 from the open part above the storage box 1 or from the feeding channel provided on the side panel of the storage box 1. The other is a closed storage box 1 with a door cover at the upper end, which can be provided with a feeding pipe on the side panel or door cover of the storage box 1, and the feeding pipe is connected to the vegetable washing pool. When the laver 200 material in the storage cavity 101 enters the sorting cavity 201 through the grate groove 202, the laver 200 material in the vegetable washing pool will also be continuously supplied to the storage cavity 101 to maintain the continuity of the laver 200 material sorting.

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

[0037] The grate disc 203 is a circular ring-shaped structural member, and its main function is to form the grate groove 202 for screening the laver 200. The gasket 204 is located between the grate discs 203 and is used to adjust and maintain the gap between the grate discs 203, that is, the size of the grate groove 202. The grate discs 203 and the gaskets 204 are arranged alternately in the height direction of the sorting box 2, so that a plurality of grate grooves 202 can be formed between two adjacent grate discs 203.

[0038] The combination of multiple grate discs 203 and washers 204 can more accurately control the size of the grate groove 202, thereby improving the sorting accuracy and effectively separating foreign objects of different sizes and shapes. By replacing washers 204 of different thicknesses, the size of the grate groove 202 can be easily adjusted to meet the needs of sorting foreign objects of different individual sizes in the laver 200 material. When the grate disc 203 or the washer 204 is worn, it can be replaced separately without replacing the entire thing, reducing maintenance costs and downtime.

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

[0040] It should be noted that, for the primary sorting, the main purpose is to sort out the larger debris in the laver 200, such as thick ropes, gloves, stones, shells, etc., and a gap value of 1.5mm-5mm is required. For the fine sorting, generally, the gap value of the grate groove 202 is between 0.6mm-1.5mm after the primary sorting and before shredding. For the fine sorting, in the fine sorting state, the gap value of the slot is 0.5mm-1mm when the laver 200 is not shredded, and it is 0.2mm-0.6mm after the laver 200 is shredded.

[0041] For example, the grate groove 202 of the embodiment of the present invention has a H value of 0.2 mm, 1 mm or 5 mm, which is suitable for fine sorting, fine sorting and rough sorting. Compared with the related art, the present invention is not limited to the thickness of the cleaning knife, so the grate groove 202 can be made into a relatively small value. The grate groove 202 of the traditional blade-type picking device can only be 0.5 mm or more, while the grate groove 202 value H of the high-pressure water cleaning seam-type laver foreign matter sorting device 100 of the present invention can be 0.2 mm, which significantly improves the picking rate of foreign matter in the laver 200.

[0042] In some embodiments, the hollow shaft 4 extends along the height direction of the sorting box 2, 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 to the multiple grate grooves 202 in the height direction of the sorting box 2.

[0043] The hollow shaft 4 extends along the height direction of the sorting box 2, ensuring that the nozzle 5 can cover the entire height range of the sorting box 2, thereby achieving the cleaning of the grate groove 202 during the entire sorting process. The design of the hollow shaft 4 makes the delivery of high-pressure water more centralized and efficient, reducing the waste of water resources. A plurality of nozzles 5 are used, which helps to improve the uniformity and efficiency of cleaning. The plurality of nozzles 5 are arranged at intervals along the axial direction of the hollow shaft 4, which can ensure that each grate groove 202 corresponds to at least one nozzle 5, ensuring the accuracy of the seam cleaning operation. The plurality of nozzles 5 correspond one-to-one with the plurality of grate grooves 202 in the height direction of the sorting box 2. Such a design ensures that each grate groove 202 can be effectively cleaned, ensures the comprehensiveness of the seam cleaning operation, and avoids congestion problems caused by certain areas not being flushed.

[0044] Since each grate groove 202 has a corresponding nozzle 5 for cleaning, it can be ensured that the obstruction in the grate groove 202 is completely removed, thereby increasing the continuous operation time of the sorting device. The nozzles 5 are arranged at intervals to make the cleaning more uniform, thereby avoiding the decline in sorting effect caused by incomplete local cleaning. If it is necessary to focus on cleaning the grate groove 202 at a specific height, the water pressure or opening time of the corresponding nozzle 5 can be adjusted in a targeted manner, thereby increasing the flexibility of cleaning. Due to the improvement in cleaning efficiency, the number of downtime maintenance caused by the blockage of the grate groove 202 is reduced, thereby reducing the maintenance cost. The sorting device can sort the foreign matter of the laver 200 more efficiently and stably, thereby increasing 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 cylinder 207. The top plate 205 is disposed on the top grate plate 203, the discharge seat cylinder 207 is disposed on the bottom grate plate 203 and extends along the height direction of the sorting box 2, the bottom plate 206 blocks the discharge seat cylinder 207, and the discharge pipe 3 is connected to the discharge seat cylinder 207.

[0046] The top plate 205 is arranged on the top grate plate 203, and its function is to seal the top grate plate 203, block the top inlet and outlet of the material, and ensure the closedness inside the sorting box 2. The bottom plate 206 blocks the discharge seat cylinder 207, which is located at the bottom of the sorting box 2, closes the bottom of the sorting box 2, and serves as a support and sealing structure for the discharge seat cylinder 207. The bottom plate 206 may be designed with components for fixing and sealing to ensure the closedness inside the sorting box 2. The discharge seat cylinder 207 is arranged on the bottom grate plate 203 and extends along the height direction of the sorting box 2. It serves as a channel for sucking the laver material 200 and conveying the separated laver 200 to the discharge pipe 3. The design of the discharge seat cylinder 207 can be a straight cylinder or have a certain taper to facilitate the smooth conveying of materials and reduce blockage. The discharge pipe 3 is communicated with the discharge seat cylinder 207, and serves as a passage for the laver 200 material to be discharged from the sorting box 2, and is connected to a negative pressure pump to realize the suction and discharge of the material.

[0047] The design of the top plate 205 and the bottom plate 206 ensures that the materials inside the sorting box 2 will not overflow or leak out, and maintains the stability and continuity of the materials in the sorting box 2. The design of the bottom plate 206 blocking the discharge seat cylinder 207 can prevent the materials from flowing out from the bottom during the sorting process. The sealing effect of the top plate 205 and the bottom plate 206 improves the sealing of the sorting box 2, helps to keep the interior clean and reduce environmental pollution. The design of the discharge seat cylinder 207 is conducive to the flow of materials during the sorting process, reduces the risk of material blockage, and improves the sorting efficiency and equipment reliability.

[0048] In some embodiments, connecting holes for the connecting rod 6 to pass through are provided on the top plate 205 , the grate plate 203 , the discharge seat cylinder 207 and the bottom plate 206 . The top plate 205 , the grate plate 203 , the discharge seat cylinder 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, the grate plate 203, the discharge seat cylinder 207 and the bottom plate 206 are provided with connection holes for the connection rod 6 to pass through. The design of these holes ensures that the components can be accurately aligned and connected together. The size and position of the connection holes need to accurately match the size of the connection rod 6 to ensure the stability of the components and the firmness of the connection. The connection rod 6 is used to connect the components such as the top plate 205, the grate plate 203, the discharge seat cylinder 207 and the bottom plate 206 into a whole, thereby enhancing the structural strength and stability of the sorting box 2. The connection rod 6 may be designed with threads or other locking mechanisms to facilitate the installation and removal of the components. The washer 204 is sleeved on the connection rod 6, and its function is to buffer the direct contact between the connection rod 6 and the connection holes of each component, reduce wear, and provide a certain 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] Through the design of the connecting rod 6 and the connecting hole, the structure of the sorting box 2 is more stable and can withstand the mechanical force and vibration generated during the sorting process. The connection design between the components allows for quick disassembly and assembly, which is convenient for maintenance and replacement of worn parts. The use of the gasket 204 reduces the direct friction between the connecting rod 6 and the connecting hole, extending the service life of the component. The adjustment space provided by the gasket 204 allows fine adjustment of the component position during installation or maintenance to ensure accurate alignment between the components.

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

[0052] like Figure 6 As shown, the connecting hole is arranged on the raised portion 2031, so that the connecting rod 6 will be appropriately away from the outer peripheral surface of the principle grate disc 203, which can reduce the obstruction of the connecting rod 6 to the grate groove 202, that is, a larger and more complete grate groove 202 ring can be obtained to improve the sorting effect.

[0053] In some embodiments, the driving assembly includes a bearing seat 7, a driving motor 8, a first bevel gear 9 and a second bevel gear 10. The bearing seat 7 is arranged on the bottom plate 206, the hollow shaft 4 is rotatably arranged on the bearing seat 7 and one end thereof extends into the sorting box 2, the first bevel gear 9 is arranged at the bottom of the hollow shaft 4, the second bevel gear 10 is arranged on the output shaft of the driving motor 8, and the first bevel gear 9 is meshed with the second bevel gear 10.

[0054] like Figure 2 and Figure 3 As shown, the bearing seat 7 is arranged on the bottom plate 206, which serves as a supporting structure for installing and fixing the bearing seat 7 so that the hollow shaft 4 can rotate thereon. The bearing seat 7 needs to have sufficient strength and stability to ensure the stability and safety of the hollow shaft 4 when rotating at high speed. The drive motor 8 is the core component that provides power, and it drives the entire sorting device to work by rotating the output shaft. The drive motor 8 may have a certain level of protection to adapt to possible humid or dusty environments, and needs to have sufficient power to meet the sorting requirements.

[0055] The first bevel gear 9 is arranged at the bottom of the hollow shaft 4 and meshes with the second bevel gear 10 to transmit the power of the drive motor 8 to the hollow shaft 4. The second bevel gear 10 is arranged 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 can achieve precise power control and speed adjustment to ensure the normal operation of the sorting device.

[0056] The design of the bearing seat 7 ensures the stable rotation of the hollow shaft 4 and reduces vibration and noise. Through the meshing of the bevel gears, the hollow shaft 4 can be driven accurately to ensure the efficiency of the sorting process. The transmission method of the bevel gear has higher reliability and durability in long-term operation compared to direct connection or other transmission methods. The design of the bevel gear allows the gears to be replaced individually without replacing the entire drive assembly, reducing maintenance costs. The design of this drive assembly can adjust the speed and torque according to different sorting requirements by replacing bevel gears with different parameters.

[0057] In some embodiments, a sealing ring or a sealing adhesive is provided between the bearing seat 7 and the bottom plate 206 .

[0058] The sealing ring or sealant is used to seal the gap between the bearing seat 7 and the bottom plate 206 to prevent the leakage of grease and the entry of foreign matter such as dust. In these embodiments, the sealing effect between the bearing seat 7 and the bottom plate 206 is improved, which effectively prevents the leakage of grease and the entry 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 tube 1101 and a first flange 1102 and a second flange 1103 provided at both ends of the central tube 1101. The first flange 1102 is rotatably connected to the central tube 1101, and the first flange 1102 is connected to the hollow shaft 4. The second flange 1103 is connected to the water pump so that the high-pressure water output by the water pump is delivered to the hollow shaft 4 through the rotary joint 11.

[0060] The center tube 1101 is the main part of the rotary joint 11, which is used to connect and transport high-pressure water. The first flange 110 is located at one end of the center tube 1101, and is rotatably connected to the center tube 1101 for connection with the hollow shaft 4. The second flange 1103 is located at the other end of the center tube 1101, and is connected to the water pump for receiving the high-pressure water output by the water pump. The first flange 1102 is connected to the hollow shaft 4, allowing the high-pressure water to be continuously transported to the hollow shaft 4 through the rotary joint 11 when the hollow shaft 4 rotates. The high-pressure water output by the water pump enters the center tube 1101 through the second flange 1103, and is then transported to the hollow shaft 4 through the rotary joint 11, and finally reaches the nozzle 5 for spraying.

[0061] The use of the rotary joint 11 ensures that the supply of high-pressure water will not be interrupted during the rotation of the hollow shaft 4, thereby ensuring the continuity and effectiveness of the cleaning process. The sealing design of the rotary joint 11 reduces the leakage of high-pressure water at the connection point and improves the sealing performance of the system. The design of the rotary joint 11 reduces equipment failures caused by interruption or leakage of high-pressure water supply and improves the reliability of the entire sorting device. The structural design of the rotary joint 11 makes maintenance and replacement more convenient, reducing maintenance costs and time.
