Description

Technical Field

[0001] This invention relates to the field of kelp cleaning technology, specifically to a kelp cleaning and sand removal device. Background Technology

[0002] In the existing kelp processing industry, bubble washing is a commonly used cleaning method. This technology generates a large number of fine bubbles by installing aeration devices at the bottom of the washing tank. The bubbles then rise and physically wash the kelp surface to remove mud and other adhering substances.

[0003] This cleaning method has two problems in use. First, it consumes a lot of water. In order to maintain an effective cleaning environment and dilute the detached impurities, the equipment usually needs to continuously inject fresh water or maintain a large volume of cleaning water, resulting in high water consumption per unit weight of kelp and low water utilization efficiency.

[0004] Secondly, its water renewal efficiency is low. Throughout the cleaning cycle, the kelp is immersed in the same pool of water with a fixed composition. As the cleaning process continues, the mud, organic impurities, and some mucus detached from the kelp surface accumulate in the water, causing the cleaning solution to become turbid rapidly. This gradually deteriorating water quality not only drastically reduces the effectiveness of subsequent bubble cleaning but also leaves the kelp in a "dirty water bath," making it easy for detached impurities to re-attach, causing secondary pollution and affecting the final cleaning quality. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The core of the present invention lies in the forced replacement of clean water and sewage. After the kelp is bubble-washed in the cleaning water tank, the double-layer filter plate moves up to filter the kelp out of the sewage. Then the double-layer filter plate is closed by the moving mechanism, which becomes a piston relative to the cleaning water tank to force the sewage located on the lower side of the double-layer filter plate to be discharged. During the descent, the clean water on the upper side is discharged into the cleaning water tank. The sewage and clean water are separated by the double-layer filter plate until all the sewage is discharged. The double-layer filter plate is then released, so that the kelp in the cleaning water tank can be cleaned normally. This switching mode can ensure the purity of the water during bubble washing and will not cause the situation of not being able to clean properly due to washing in sewage. On the other hand, by replacing long-term soaking cleaning with multiple clean water washes, it is beneficial to quickly remove stains and control the cleaning precision. It also reduces the adverse effects of long-term soaking of kelp on the quality of kelp.

[0021] 2. This invention also has the ability to purify and circulate water. The pressure exerted when the double-layer filter plates are pressed down allows the wastewater on the lower side of the double-layer filter plates to be discharged into the storage tank. At the same time, the purified water on the upper side of the mounting plate can be discharged to the upper side of the double-layer filter plates. The purified water on the upper side can also assist the double-layer filter plates to be pressed down further by its own weight. The water circulation mechanism can not only filter impurities in the wastewater, but also adsorb odors in the wastewater. Furthermore, the kelp in the cleaning tank requires a certain amount of time to be washed. This time period is the time for impurities in the wastewater in the storage tank to settle and for odors to be adsorbed, thus increasing the efficiency of water resource utilization.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-12 The present invention provides a technical solution: a kelp cleaning and sand removal device, including a cleaning water tank 1, a storage water tank 2 is provided on one side of the cleaning water tank 1, a double-layer filter plate 3 is movably installed in the cleaning water tank 1, a movable filter plate 4 is movably inserted in the double-layer filter plate 3, and a bubble generator 8 is installed on the lower side of the cleaning water tank 1.

[0037] The movable mechanism 5 includes a T-shaped block 504 and an L-shaped block 513. A T-shaped block 504 is fixedly installed on one side of the movable filter plate 4, and two sets of L-shaped blocks 513 are fixedly installed on the other side of the movable filter plate 4.

[0038] The pressing mechanism 6 includes a connecting frame 601. The connecting frame 601 is movably mounted on the cleaning water tank 1, and one end of the connecting frame 601 is mounted on the double-layer filter plate 3.

[0039] The water circulation mechanism 7 includes a mounting plate 704, a sediment filter cylinder 705, and an adsorption filter layer 706. The mounting plate 704 is installed inside the storage tank 2. The sediment filter cylinder 705 is fixedly installed in an array on the lower side of the mounting plate 704. The adsorption filter layer 706 is installed inside the sediment filter cylinder 705.

[0040] The discharge mechanism 9 includes a cover plate 901 and a push plate 904. The cover plate 901 is rotatably mounted on the upper side of the storage tank 2, and the push plate 904 is movably disposed on the cover plate 901.

[0041] This equipment achieves multiple water purification and washing of kelp through the separate switching of wastewater and purified water. Compared with the traditional soaking and flowing water washing method, this washing method uses less water, is more targeted and controllable, and achieves higher cleanliness. The equipment is also equipped with a water circulation mechanism 7 for water circulation. Based on the equipment's feature of separating wastewater and purified water, the wastewater discharged per batch has a lower impurity content and lower pollution level compared to wastewater from traditional flowing water tanks. Under the filtration of the silt filter cartridge 705 and the adsorption filter layer 706, the purity is high, which helps to improve the efficiency of water filtration.

[0042] Furthermore, the movable mechanism 5 also includes a first movable groove 501, a return spring 502, a fixed rod 503, a T-shaped block 504, a second movable groove 505, a telescopic motor 506, and an arc-shaped abutment 507. The movable filter plate 4 has an array of first movable grooves 501, a return spring 502 is installed in the first movable groove 501, a fixed rod 503 is movably inserted in the first movable groove 501, the fixed rod 503 is fixedly installed on the inner side of the double-layer filter plate 3, one end of the fixed rod 503 abuts against the return spring 502, a second movable groove 505 is opened on one side of the double-layer filter plate 3, a T-shaped block 504 is in the second movable groove 505, a telescopic motor 506 is fixedly installed on the cleaning water tank 1, an arc-shaped abutment 507 is fixedly installed on the output shaft of the telescopic motor 506, and the arc-shaped abutment 507 abuts against the T-shaped block 504. The structure is a movable filter plate 4. The double-layer filter plate 3 has sealed edges and an empty middle. It can be regarded as a square frame with non-contact filter plates on the upper and lower sides. The movable filter plate 4 is inserted between the filter plates and is in close contact. The size and position of the pores on the movable filter plate 4 and the double-layer filter plate 3 are matched. However, the total length of the movable filter plate 4 is less than that of the double-layer filter plate 3, and the length difference is greater than the diameter of the pores. This allows the movable filter plate 4 to move within the double-layer filter plate 3 and to close the filter holes. The shape of the T-shaped block 504 allows the arc-shaped abutment block 507 to allow the movable filter plate 4 to move up and down within a certain range after pushing the movable filter plate 4 while maintaining the pushing state. This provides the conditions for the movable filter plate 4 to close in the movable state later.

[0043] Furthermore, the active mechanism 5 also includes guide rods 508, guide holes 509, limiting rods 510, limiting grooves 511, insertion grooves 512, and sealing rings 514. Four sets of guide rods 508 are fixedly installed inside the cleaning water tank 1. Guide holes 509 are opened at the four corners of the double-layer filter plate 3, and the guide rods 508 are inserted into the guide holes 509. Limiting rods 510 are fixedly installed on the two sets of guide rods 508 on the left side. The length of the limiting rods 510 is less than that of the guide rods 508. The length of the guide rod 508 is specified. On the left side, two sets of guide holes 509 are provided with limiting grooves 511. The shape of the limiting grooves 511 is adapted to the shape of the limiting rod 510. The limiting rod 510 is inserted into the limiting grooves 511. An insertion groove 512 is provided in the limiting grooves 511. The position of the L-shaped block 513 is opposite to the position of the insertion groove 512. A sealing ring 514 is fixedly installed on the outer side of the double-layer filter plate 3. The sealing ring 514 abuts against the inner wall of the cleaning water tank 1. This structure is a closed structure for the movable filter plate 4. There is a clear gap between the ends of the limiting rod 510 and the guide rod 508. When the double-layer filter plate 3 is in a high position, the upper end of the limiting rod 510 is on the lower side of the insertion slot 512. The movable filter plate 4 is pushed so that the L-shaped block 513 is pushed into the insertion slot 512. Then, when the double-layer filter plate 3 descends, the L-shaped block 513 will descend and engage with the limiting rod 510 until it reaches the bottom of the descent and does not abut against the limiting rod 510. Under the action of the reset spring 502, the movable filter plate 4 returns to its original position, and the aperture is aligned so that filtration can be performed. This realizes the cycle of the double-layer filter plate 3 moving upward in the open state, changing to the closed state after moving to the top, moving downward in the closed state, and changing to the open state after moving to the bottom.

[0044] Furthermore, the pressing mechanism 6 also includes a connecting side plate 602, a first threaded sleeve 603, a fixed side plate 604, a rotary motor 605, and a first screw 606. The first threaded sleeve 603 is fixedly installed on the connecting frame 601, and the connecting side plates 602 are fixedly installed on both sides of the connecting frame 601. The connecting side plates 602 are located on the front and rear sides of the upper end of the double-layer filter plate 3. The fixed side plate 604 is fixedly installed on one side of the cleaning water tank 1. The rotary motor 605 is fixedly installed on the fixed side plate 604, and the first screw 606 is fixedly installed on the output shaft of the rotary motor 605. The first screw 606 is rotatably installed on the cleaning water tank 1, and the first threaded sleeve 603 is threadedly connected to the first screw 606. This structure is the driving structure for the double-layer filter plate 3 to move up and down, and it is also the structure for sewage discharge. The shape of the connecting frame 601 ensures that the upper side of the cleaning water tank 1 is unobstructed in the left and right directions, providing conditions for the subsequent discharge of kelp. The connecting side plate 602 is not only the connecting structure between the double-layer filter plate 3, but also the limiting structure for kelp, so that the filtered kelp will not scatter in the front and back directions.

[0045] Furthermore, the pressing mechanism 6 also includes a limiting slot 607, a limiting block 608, and a movable hole 609. A limiting slot 607 is provided on the lower side of the connecting side plate 602. Limiting blocks 608 are fixedly installed on the front and rear sides of the upper end of the double-layer filter plate 3. The limiting blocks 608 are inserted into the limiting slots 607. Movable holes 609 are provided on both the limiting blocks 608 and the connecting side plate 602. The position and shape of the movable holes 609 are adapted to the position and shape of the guide rod 508 and the limiting rod 510. The raising process of the connecting frame 601 allows the double-layer filter plate 3 to be completely extracted from the cleaning water tank 1, enabling the key component, the double-layer filter plate 3, and its associated structures to be disassembled as a whole. The movement of the movable filter plate 4 within the double-layer filter plate 3 is passively triggered and has no rigid structural connection with other components. The structure is simple, reducing replacement costs and increasing the convenience of equipment cleaning and maintenance.

[0046] Furthermore, the water circulation mechanism 7 also includes a sewage discharge pipe 701, a clean water inlet pipe 702, a solenoid valve 703, and a drain outlet 707. The sewage discharge pipe 701 and the clean water inlet pipe 702 are fixedly installed between the clean water tank 1 and the storage water tank 2. The sewage discharge pipe 701 is located below the clean water inlet pipe 702. Solenoid valves 703 are fixedly installed on both the sewage discharge pipe 701 and the clean water inlet pipe 702. The bottom of the storage water tank 2 is tilted to the left at the front end. A drain outlet 707 is fixedly installed at the lower left corner of the front side of the storage water tank 2. A water outlet plug is provided on the drain outlet 707. This structure is a water circulation structure. Under the pressure of the double-layer filter plate 3, sewage flows from the sewage discharge pipe 701 to the lower side of the mounting plate 704. The clean water on the upper side of the mounting plate 704 is injected into the upper side of the double-layer filter plate 3, completing the forced switching of clean water and sewage. At the same time, the shape of the inner side of the storage tank 2 has a certain guiding effect on the deposited silt, making the discharge of silt more convenient. Meanwhile, the misalignment between the sewage discharge pipe 701 injection position and the silt deposition position also reduces the agitation effect of sewage on silt during injection. Due to the presence of the mounting plate 704, sewage is forcibly filtered and purified from the lower side to the upper side of the mounting plate 704, increasing the sewage purification capacity.

[0047] Furthermore, the water circulation mechanism 7 also includes a first limiting ring 708, a fixed long rod 709, a locking groove 710, an installation long cylinder 711, and locking blocks 712. The first limiting ring 708 is placed at a hole on the upper side of the mounting plate 704. The fixed long rod 709 is fixedly installed on the lower side of the first limiting ring 708. Two sets of locking grooves 710 are opened on the lower side of the fixed long rod 709. The installation long cylinder 711 is movably sleeved on the fixed long rod 709. Two sets of locking blocks 712 are fixedly installed on the lower side of the installation long cylinder 711. The locking blocks 712 engage within the locking grooves 710. An adsorption filter layer 706 is fixedly installed in an array on the outer side of the locking blocks 712. This structure facilitates the removal of the adsorption filter layer 706. The adsorption filter layer 706 needs to be replaced after a period of use. This structure, combined with the open storage water tank 2, makes it easy to remove and replace the adsorption filter layer 706, increasing the convenience of using the equipment.

[0048] Furthermore, the water circulation mechanism 7 also includes a first handle 713, a square frame 714, a second threaded sleeve 715, and a second screw 716. The first handle 713 is fixedly installed on the upper side of the mounting plate 704, and the square frame 714 is fixedly installed inside the storage tank 2. The lower edge of the mounting plate 704 rests on the square frame 714, and the second threaded sleeve 715 is fixedly installed at the corner of the square frame 714. The second screw 716 is movably inserted at the corner of the mounting plate 704 and is threaded into the second threaded sleeve 715. This structure allows the mounting plate 704 to be disassembled. By fixing the mounting plate 704 through a fixed method, the mounting plate 704 not only has good support, adjustment, and sealing effects, but also allows the mounting plate 704 to not be completely fitted to the inside of the storage tank 2, making it easy to remove and increasing the convenience of using the equipment.

[0049] Furthermore, the discharge mechanism 9 also includes a water injection groove 902, a second limiting ring 903, and a pushing rod 905. The water injection groove 902 is provided on the upper side of the cover plate 901, and the second limiting ring 903 is fixedly installed on the upper side of the cover plate 901. The pushing rod 905 is movably inserted into the second limiting ring 903, and a push plate 904 is fixedly installed at one end of the pushing rod 905. The length and height of the push plate 904 are adapted to the spacing and height of the two sets of connecting side plates 602. This structure allows the push plate 904 to be pushed by moving the pushing rod 905 to discharge the kelp during use. It has a simple structure, strong operability, and under normal conditions, the cover plate 901 can be pressed down by its own weight, replacing the locking structure of the cover plate 901.

[0050] Furthermore, the discharge mechanism 9 also includes a second handle 906, finger grooves 907, and a guide plate 908. The second handle 906 is fixedly installed at one end of the push rod 905. Two sets of finger grooves 907 are provided on the upper left side of the push plate 904. The left end of the cover plate 901 is rotatably installed on the left side of the upper side of the storage tank 2. The guide plate 908 is fixedly installed on the right end of the cleaning tank 1. This structure allows the push plate 904 to be used as a handle when the cover plate 901 is opened. The finger grooves 907 do not penetrate the push plate 904. After the cover plate 901 is unfolded, the push rod 905 and the push plate 904, due to their own shape and weight, limit the cover plate 901, ensuring stable opening. The guide plate 908 not only guides the discharged seaweed but also partially shields the telescopic motor 506, the rotary motor 605, and the first screw 606, increasing the stability of the equipment during use.

[0051] Working Principle: In the initial state, the storage tank 2 contains sufficient clean water, the double-layer filter plate 3 is placed in the cleaning tank 1, and there is kelp on the double-layer filter plate 3. The cleaning tank 1 contains clean water, and the bubble generator 8 cleans the kelp. After cleaning, the double-layer filter plate 3 rises. The rising principle of the double-layer filter plate 3 is that the output shaft of the rotary motor 605 rotates, driving the first screw 606 to rotate. Through the thread action between the screw and the first screw sleeve 603, the connecting frame 601 rises, thereby driving the double-layer filter plate 3 to rise. The same principle applies when it descends, filtering the kelp out of the sewage. When the double-layer filter plate 3 is at a high position, it changes to a closed state. The principle of the replacement is explained above. At this time, the sewage discharge pipe 701 and the clean water inlet pipe 702 are opened under the control of the solenoid valve 703. The double-layer filter plate 3 descends and presses the sewage into the storage tank 2 from the sewage discharge pipe 701. The water level in the storage tank 2 rises and enters the upper side of the double-layer filter plate 3 from the clean water inlet pipe 702 until all the sewage is discharged into the storage tank 2. At this time, the lower side of the mounting plate 704 is mainly sewage, and the upper side of the mounting plate 704 is the filtered circulating water. When the double-layer filter plate 3 descends to the lower side, it switches to the open state. Then the kelp on the double-layer filter plate 3 continues to be washed. The double-layer filter plate 3 rises and starts the next cycle.

[0052] After multiple rinses with purified and circulating water, the kelp is brought to the upper side by the double-layer filter plate 3. At this time, the upper end of the double-layer filter plate 3 is flush with the lower end of the push plate 904. Pushing the push rod 905 causes the kelp to be discharged. After the push plate 904 is reset, the kelp to be cleaned can be placed on the double-layer filter plate 3.

[0053] When disassembling the double-layer filter plate 3, raise the double-layer filter plate 3 to detach it from the cleaning water tank 1, and then pull out the double-layer filter plate 3. When replacing the adsorption filter layer 706, remove the first limiting ring 708, rotate the first limiting ring 708 to disengage the locking block 712 from the locking groove 710, replace the new adsorption filter layer 706 and assemble it on the fixed long rod 709, and then place the adsorption filter layer 706 in the sediment filter cylinder 705.
