Description

Technical Field

[0001] The present invention relates to the technical field of kelp processing, and more particularly, to an intelligent drying system capable of drying kelp. Background Art

[0002] As is well known, kelp is a kind of seafood with high nutritional value. Kelp is a brown alga with a brown thallus. Kelp consists of three parts: a holdfast, a stipe, and a blade. The holdfast is forked and branched for attaching to the seabed rock; the stipe is short and thick, cylindrical; the blade is long and narrow, ribbon-shaped.

[0003] At present, there is less naturally growing kelp, and it mainly depends on artificial cultivation. The method of artificial cultivation is to set up multiple rows of cultivation frames composed of several floats in the sea area. Several seedling ropes are tied between every two rows of cultivation frames, and kelp grows on the seedling ropes. After the kelp matures, fishermen use small boats to fish the kelp out of the sea water, then transport it ashore, and then process it.

[0004] Fresh kelp is usually dried and processed into dried kelp. The drying process can refer to the utility model patents with the authorized announcement numbers of CN216668237U and CN216662198U. The drying process is usually carried out in a drying room. A conveying chain capable of moving kelp is arranged in the drying room to achieve continuous batch operation; during the operation process, operators manually pick up the fresh kelp to be processed and hang it on the hooks or lifting tools of the conveying device. The hooks or lifting tools are at a certain height from the ground to ensure that the fresh kelp is naturally unfolded in the vertical direction after being hung up, that is, the fresh kelp is suspended in mid-air. Because the fresh kelp to be processed is large in volume, heavy in weight, and has a smooth surface, it is very inconvenient for workers to operate, time-consuming and laborious, with a large labor intensity, low efficiency, high cost, and manual feeding also results in a low degree of automation of the entire drying device and cannot meet the requirements of high-efficiency large-scale drying operations.

[0005] Referring to the utility model patents with the authorized announcement numbers of CN213273484U and CN220403034U, the number of kelp dried in the drying box is limited and cannot meet the requirements of large-scale drying operations. Summary of the Invention

The second lifting mechanism is used to raise or lower the third group of Y-axis running roller positioning frames (that is, to raise or lower the third group of Y-axis running rollers 508). In the initial state, the plane where the third group of Y-axis running rollers 508 is located is lower than the plane where the second group of X-axis running rollers 507 is located. The first baffle 509 is fixedly connected to the front frame 501, and the second baffle 510 is fixedly connected to the rear frame 503.When the lifting mechanism 1 operates to raise the first set of Y-axis running rollers 505, the plane where the first set of Y-axis running rollers 505 is located is at the same horizontal level as the plane where the second set of Y-axis running rollers 506 is located, and at this time, the plane where the first set of Y-axis running rollers 505 is located is higher than the plane where the first set of X-axis running rollers 504 is located. When the lifting mechanism 2 operates to raise the third set of Y-axis running rollers 508, the plane where the third set of Y-axis running rollers 508 is located is at the same horizontal level as the plane where the second set of Y-axis running rollers 506 is located, and at this time, the plane where the third set of Y-axis running rollers 508 is located is higher than the plane where the second set of X-axis running rollers 507 is located. The front frame 501 is located inside the box body 101 of the drying chamber 100, and the front frame 501 is close to the heating tube 103.

[0077] There is a gap between the input end of the second chain conveyor 700 and the rear frame 503, and this gap is used to provide an opening and closing space for the fourth telescopic sealing door installed at the outlet 301.

[0078] Reference Figure 7 、 Figure 26 and Figure 28 As shown in FIGS. and, a first lifting turntable 3000 is provided at the intersection of the output end of the second chain conveyor 700 and the input end of the intermediate chain conveyor 800. The first lifting turntable 3000 is provided with a platform, a lifting mechanism, and a rotating mechanism. The lifting mechanism can raise or lower the platform, and the rotating mechanism can rotate the platform. A second lifting turntable 4000 is provided at the intersection of the output end of the intermediate chain conveyor 800 and the input end of the first chain conveyor 600. The structure of the second lifting turntable 4000 is the same as the structure of the first lifting turntable 3000.

[0079] The working process of the above intelligent drying system is introduced below:

[0080] As Figure 29As shown in the figure, the first material rack includes a bottom frame 1-1, a top frame 1-2, a side frame 1-3, a side frame 1-4, a left support plate 1-5, and a right support plate 1-6. The bottom frame 1-1, the top frame 1-2, the side frame 1-3, and the side frame 1-4 are connected together, and the entire first material rack is transparent from front to back. The left support plate 1-5 is fixedly connected to the inner side surface of the side frame 1-3, and the right support plate 1-6 is fixedly connected to the inner side surface of the side frame 1-4. The left support plate 1-5 and the right support plate 1-6 are arranged oppositely and on the same horizontal plane. The left support plate 1-5 and the right support plate 1-6 form a layer of support mechanism. As can be seen from the figure, three layers of support mechanisms are provided. It should be noted that the three layers of support mechanisms are only examples, and more layers of support mechanisms can be provided. The bottom frame 1-1, the top frame 1-2, the side frame 1-3, and the side frame 1-4 form a frame structure, which is conducive to ventilation and drying and improves work efficiency.

[0081] First step, referring to Figure 7 , the first material rack is located on the intermediate chain conveyor 800; referring to Figure 2 、 Figure 4 、 Figure 7 、 Figure 12 , the loading device 1000 is located beside the first material rack.

[0082] Second step, the loading device 1000 performs an automatic loading operation. The specific process is as follows:

[0083] Step S201, start the baffle type ramp conveyor 1100. The worker places the kelp placement board on the baffle type ramp conveyor 1100. Fresh kelp to be dried is placed on the kelp placement board. The kelp placement board 8 is transferred to the horizontal conveyor 1200 as the baffle type ramp conveyor 1100 is lifted, as Figure 12 shown.

[0084] Step S202, referring to Figure 30, the initial states of the first push plate 1030 and the second push plate 1031 are in the natural hanging state. The controller issues commands to start the first electric push rod 1028 and the second electric push rod 1029. The telescopic rod of the first electric push rod 1028 extends forward, and the telescopic rod of the second electric push rod 1029 extends forward. During the forward movement of the first push plate 1030, the lower end of the first push plate 1030 touches the kelp placement plate 8 and is forced to rotate upward by a certain angle. When the first push plate 1030 and the second push plate 1031 move to the back of the kelp placement plate 8, the first push plate 1030 and the second push plate 1031 return to the hanging state. Then the controller commands the telescopic rods of the first electric push rod 1028 and the second electric push rod 1029 to retract backward, and the first push plate 1030 and the second push plate 1031 move backward. The upper part of the first push plate 1030 abuts against the telescopic rod of the first electric push rod 1028. Similarly, the upper part of the second push plate 1031 abuts against the telescopic rod of the second electric push rod 1029. The lower end of the first push plate 1030 pushes the kelp placement plate 8 toward the first horizontal direction support plate 1034, and the lower end of the second push plate 1031 pushes the kelp placement plate 8 toward the second horizontal direction support plate 1035. Thus, the kelp placement plate 8 is translated onto the first horizontal direction support plate 1034 and the second horizontal direction support plate 1035. Refer to Figure 31 , the first horizontal direction support plate 1034 and the second horizontal direction support plate 1035 support the kelp placement plate 8.

[0085] Step S203, the controller commands the first rotary cylinder 1032 and the second rotary cylinder 1033 to act to turn the first horizontal direction support plate 1034 and the second horizontal direction support plate 1035 downward by 90°, and the kelp placement plate 8 freely drops onto the tray 1017. If the position of the kelp placement plate 8 supported by the first horizontal direction support plate 1034 and the second horizontal direction support plate 1035 is deviated, the first guide plate 1036 and the second guide plate 1037 can guide the freely dropping kelp placement plate 8 to guide the orientation of the kelp placement plate 8 so that the kelp placement plate 8 accurately drops onto the tray 1017.

[0086] Step S204, the controller commands the first telescopic drive motor 1018 to work to make the tray 1017 extend forward (extend toward the first material rack), and the tray 1017 carries the kelp placement plate 8 into the first material rack, as Figure 13 、 Figure 14 、 Figure 15 shown. Refer to Figure 32 , the tray 1017 is located above a layer of support mechanism formed by the left support plate 1-5 and the right support plate 1-6. At this time, the kelp placement plate 8 has not contacted the left support plate 1-5 and the right support plate 1-6.

[0087] Step S205, the controller instructs the lifting drive motor 1007 to work to make the first lifting plate 1016 descend, and the first lifting plate 1016 descends with the supporting plate 1017, and the kelp placing plate 8 is placed on the left support plate 1-5 and the right support plate 1-6, and the left support plate 1-5 and the right support plate 1-6 support the kelp placing plate 8 upward, and the fresh kelp 9 is located on the kelp placing plate 8, and the supporting plate 1017 is separated from the kelp placing plate 8. Figure 33 shown.

[0088] Step S206, the controller instructs the first telescopic drive motor 1018 to work to retract the support plate 1017 backward (withdraw from the material rack 1), and at this time, a kelp placement plate 8 carrying fresh kelp 9 is placed into the material rack 1.

[0089] By using the above method, kelp placing plates carrying fresh kelp can also be placed on the second and third layers of the material rack.

[0090] Step 3: Reference Figure 7 and Figure 28 , the controller instructs the middle chain conveyor 800 to operate so as to bring the material rack 1 containing fresh kelp to the first chain conveyor 600. When the material rack 1 is translated to the top of the second lifting turntable 4000, the controller instructs the second lifting turntable 4000 to move, and the platform of the second lifting turntable 4000 rises to push the material rack 1 upward, so that the material rack 1 is separated from the middle chain conveyor 800, and then the platform of the second lifting turntable 4000 rotates 90° so that the material rack 1 rotates 90°, and then the platform of the second lifting turntable 4000 descends, and the material rack 1 is pressed on the middle chain conveyor 800 and the first chain conveyor 600 at the same time, as shown in FIG. Figure 28 Then the first chain conveying device 600 operates to make the material rack 1 move horizontally toward the first material rack conveying device 400 .

[0091] Step 4: Under the instruction of the controller, the third telescopic sealing door installed at the inlet 201 of the input transition box 200 is opened. Figure 7 , Figure 26, the material rack 1 loaded with fresh kelp is translated onto the first set of X-axis running rollers 404. The first set of X-axis running rollers 404 rotates to translate the material rack 1, and the entire material rack 1 is located on the first set of X-axis running rollers 404 and blocked by the first baffle 406. Then, the third telescopic sealing door closes, and at the same time, the second telescopic sealing door 101-4 opens. Then, the controller commands the first set of Y-axis running rollers 405 to rise to lift the material rack 1 upward. While the first set of Y-axis running rollers 405 rises, the third set of Y-axis running rollers 408 also rises. Then, the first set of Y-axis running rollers 405 rotates to translate the material rack to the second set of Y-axis running rollers 407; then the second set of Y-axis running rollers 407 and the third set of Y-axis running rollers 408 rotate to translate the material rack to the third set of Y-axis running rollers 408, and the entire material rack presses on the third set of Y-axis running rollers 408, and the second baffle 410 blocks the material rack. Then, the second telescopic sealing door 101-4 closes. Then, the third set of Y-axis running rollers 408 and the first set of Y-axis running rollers 405 descend simultaneously, and the entire material rack presses on the second set of X-axis running rollers 409. Then, the controller commands the second set of X-axis running rollers 409 to rotate to translate the material rack to the input end of the third chain conveyor 900. Then, the third chain conveyor 900 operates, and the material rack moves from the input end of the third chain conveyor 900 to the output end of the third chain conveyor 900 to the right. During the process of the material rack being translated under the action of the third chain conveyor 900, the kelp in the material rack is dried.

[0092] Step 5: When the material rack moves to the output end of the third chain conveyor 900 and continues to move onto the first set of X-axis running rollers 504, the first set of X-axis running rollers 504 rotates to disengage the material rack from the third chain conveyor 900. The entire material rack then presses on the first set of X-axis running rollers 504 and is blocked by the first baffle 509. Then, under the command of the controller, the first telescopic sealing door 101-3 opens. Then, the controller commands the first set of Y-axis running rollers 505 and the third set of Y-axis running rollers 508 to rise simultaneously. The first set of Y-axis running rollers 505 jacks up the material rack; then, the first set of Y-axis running rollers 505 rotates to translate the material rack onto the second set of Y-axis running rollers 506, and the second set of Y-axis running rollers 506 rotates to translate the material rack towards the third set of Y-axis running rollers 508. The third set of Y-axis running rollers 508 rotates, and the entire material rack presses on the third set of Y-axis running rollers 508. Then, the controller commands the first set of Y-axis running rollers 505 and the third set of Y-axis running rollers 508 to descend simultaneously, and the material rack presses on the second set of X-axis running rollers 507. Then, the first telescopic sealing door 101-3 closes, and at the same time, the fourth telescopic sealing door at the outlet 301 opens. Then, the second set of X-axis running rollers 507 rotates to translate the material rack containing dried kelp towards the second chain conveyor 700, and the material rack containing dried kelp moves entirely onto the second chain conveyor 700. Then, the fourth telescopic sealing door at the outlet 301 closes.

[0093] Step 6: When the material rack containing dried kelp is above the first lifting turntable 3000, the controller commands the first lifting turntable 3000 to act. The platform of the first lifting turntable 3000 rises to jack up the material rack, disengaging the material rack from the second chain conveyor 700. Then, the platform of the first lifting turntable 3000 rotates 90°, causing the material rack to rotate 90°. Then, the platform of the first lifting turntable 3000 descends, and the material rack only presses on the intermediate chain conveyor 800; then, the intermediate chain conveyor 800 operates, and the material rack translates on the intermediate chain conveyor 800. When the material rack containing dried kelp is next to the feeding device 2000 ( Figure 7 as shown by the material rack two 2 next to the feeding device 2000), the controller commands the intermediate chain conveyor 800 to stop running. A sensor can be set up to detect that the material rack containing dried kelp has moved next to the feeding device 2000 and feedback a signal to the controller.

[0094] Step 7: The controller commands the feeding device 200 to perform an automatic feeding operation. The specific process is as follows:

[0095] Step S701, the initial states of the first front claw 2030, the second front claw 2031, the first rear claw 2032, and the second rear claw 2033 are as Figure 24 shown; the second telescopic driving motor 2013 operates to extend the telescopic plate 2027 forward (extend towards the direction of the second material rack 2), the telescopic plate 2027 extends into the second material rack 2, and the telescopic plate 2027 is located above the kelp placement plate 8.

[0096] Step S702, the front claw movement driving cylinder 2034 and the rear claw movement driving cylinder 2035 act simultaneously. The telescopic rod of the front claw movement driving cylinder 2034 extends, and the telescopic rod of the rear claw movement driving cylinder 2035 also extends. The front claw connecting shaft 2028 rotates by a certain angle, and the rear claw connecting shaft 2029 rotates by a certain angle. The two front claws rotate downward by a certain angle, and the two rear claws also rotate downward by a certain angle, as Figure 25 shown. The two front claws are buckled on the edge of the kelp placement plate 8, and the two rear claws are buckled on the edge of the kelp placement plate 8.

[0097] Step S703, the second telescopic driving motor 2013 operates to retract the telescopic plate 2027 backward. The two front claws and the two rear claws take out the kelp placement plate 8 from the second material rack 2, and the kelp placement plate 8 with dried kelp moves to the initial position, and the kelp placement plate 8 is located above the conveyor belt 2036.

[0098] Step S704, the lifting driving motor 2009 operates to lower the second lifting plate 2004 to a position close to the conveyor belt 2036.

[0099] Step S705, the front claw movement driving cylinder 2034 and the rear claw movement driving cylinder 2035 act simultaneously. The telescopic rod of the front claw movement driving cylinder 2034 retracts, and the telescopic rod of the rear claw movement driving cylinder 2035 also retracts. The two front claws rotate upward by a certain angle to the initial state, and the two rear claws also rotate upward by a certain angle to the initial state. The two front claws and the two rear claws release the kelp placement plate 8, and the kelp placement plate 8 with dried kelp falls onto the conveyor belt 2036. Then, the conveyor belt 2036 further transfers the kelp placement plate 8 for subsequent collection of dried kelp.

[0100] Step S706, the lifting driving motor 2009 operates to raise the second lifting plate 2004 to prepare for taking the next kelp placement plate in the second material rack 2.

[0101] All the kelp placement plates 8 in the material rack are taken out through the above steps.

[0102] In the eighth step, the controller commands the intermediate chain conveyor 800 to operate, moving the empty second material rack 2 towards the first chain conveyor 600. When the empty second material rack 2 moves beside the feeding device 1000, the intermediate chain conveyor 800 stops operating, and the empty second material rack 2 stays beside the feeding device 1000, getting ready for feeding. Sensors can be set to detect the movement of the empty second material rack 2 beside the feeding device 1000 and feedback signals to the controller.

[0103] In the ninth step, the feeding device 1000 performs automatic feeding operations.

[0104] It can be seen that the material racks are continuously recycled, and a relatively large quantity of fresh kelp can be placed in the material racks. The entire drying system can achieve efficient large - batch kelp drying operations. It can be seen that automatic feeding and discharging are realized, reducing labor consumption, lowering labor intensity, reducing labor costs, improving operation efficiency. The processes of automatic feeding and discharging are reliable, stable, time - saving, labor - saving, and convenient to operate.

[0105] Setting the input transition box 200, output transition box 300, and telescopic sealing door helps to ensure the temperature stability inside the drying chamber 100, preventing the temperature inside the drying chamber 100 from dropping due to the output or input of the material racks.

[0106] It should be noted that other - structured conveying devices can be used to replace the third chain conveyor 900. Similarly, other - structured conveying devices can also be used to replace the first chain conveyor 600. Similarly, other - structured conveying devices can also be used to replace the second chain conveyor 700. Similarly, other - structured conveying devices can also be used to replace the intermediate chain conveyor 800.

[0107] The above description is only for the preferred embodiments of the present invention and is not used to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention.
