[0002] Kelp is a perennial large edible alga. The sporophyte is large, brown, and flat and ribbon-shaped. It is divided into a blade, a stipe, and a holdfast, and the holdfast is rhizoid-like. The blade is composed of epidermal, cortical, and medullary tissues, and there are sporangia at the lower part of the blade. It has mucus cavities and can secrete slippery substances. The holdfast is tree-like branched and is used to attach to the seabed rock and grows in the sea with relatively low water temperature.

[0003] Non-instant dried kelp products are made from fresh kelp as raw materials, which are selected, cleaned, air-dried by hanging to remove part of the moisture in the kelp, and then graded, trimmed, shaped, and low-temperature air-dried.

[0004] Although the existing intelligent drying devices can achieve precise supply of wind speed and temperature, before air-drying, a pre-treatment work needs to be carried out on the kelp, that is, the kelp needs to be cleaned before air-drying, and this operation is rather labor-consuming. Summary of the Invention

[0006] To achieve the above object, the present invention provides the following technical solution: an intelligent multi-temperature zone staged temperature-controlled air-drying device for kelp, including a temperature-controlled air-drying box and a track fixedly installed on the top surface of the inner wall of the temperature-controlled air-drying box. The track extends to the outside of the temperature-controlled air-drying box. Two symmetrically distributed first electric push doors are installed on one side of the temperature-controlled air-drying box. A plurality of sliding rods are slidably connected to the track. A first bearing plate is rotatably connected to each sliding rod. A telescopic round rod is vertically fixed to the lower surface of the first bearing plate. The lower end of the telescopic round rod is fixedly connected to a second bearing plate. A plurality of clamping components are arranged on both the first bearing plate and the second bearing plate in a circumferential array. A rotating mechanism for driving the first bearing plate and the second bearing plate to rotate intermittently and a cleaning mechanism for spraying brine on the kelp are arranged outside the temperature-controlled air-drying box.

[0007] Preferably, the clamping component includes two vertical plates vertically fixed to the lower surfaces of the first bearing plate and the second bearing plate. Spring rods are fixedly connected to the sides of the two corresponding vertical plates close to each other. The free ends of the spring rods are fixedly connected to inclined plane blocks, and the two inclined plane blocks are in contact with each other.

[0008] Preferably, the rotating mechanism includes a bottom plate fixed to the temperature-controlled air-drying box. A vertical plate is perpendicularly fixed to the upper surface of the bottom plate. Two symmetrically distributed L-shaped rods are fixedly connected to the surface of the vertical plate. A transverse frame is fixedly connected between the two L-shaped rods. A U-shaped seat is slidably connected within the transverse frame. A ratchet is rotatably connected to the U-shaped seat. A limiting spring is fixedly connected between the ratchet and the inner wall of the U-shaped seat. A first gear is integrally formed at the edge of the first bearing plate. The ratchet meshes with the first gear.

[0009] Preferably, a flat plate is vertically and slidably connected within the vertical plate. An inclined groove is formed on the surface of the flat plate. A sliding rod that is slidably adapted to the inclined groove is fixedly connected to the surface of the U-shaped seat.

[0010] Preferably, the cleaning mechanism includes a round barrel perpendicularly fixed to the upper surface of the temperature-controlled air-drying box. A water inlet pipe and a water outlet pipe that are interconnected with the round barrel are fixedly connected to the surface of the round barrel. A first valve body is installed on the water inlet pipe. A second valve body is installed on the water outlet pipe. A water spraying pipe is fixedly connected to the surface of the flat plate. Two spray nozzles are vertically distributed on the water spraying pipe. A heating pipe is arranged within the temperature-controlled air-drying box.

[0011] Preferably, a vertical rod is fixedly connected to the lower surface of the inclined groove. The lower end of the vertical rod extends into the round barrel and is fixedly connected to a round plate.

[0012] Preferably, an adjusting mechanism for adjusting the distance between the first bearing plate and the second bearing plate is arranged above the bottom plate. The adjusting mechanism includes a long rod telescopically inserted into the lower end of the sliding rod. A sliding groove is formed on the surface of the long rod. The sliding rod is of a hollow structure as a whole, and a rectangular block adapted to the sliding groove is integrally formed at the lower end. The second bearing plate is rotatably connected to the lower end of the long rod.

[0013] Preferably, a reciprocating threaded rod is rotatably connected within the sliding rod.

[0014] Preferably, three second electric push doors are installed within the temperature-controlled air-drying box. The three second electric push doors divide the interior of the temperature-controlled air-drying box into four areas, which are area one, area two, area three, and area four in sequence from the side close to the bottom plate to the side far from the bottom plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] By setting up a clamping component, the kelp can be clamped between the two inclined blocks, so that the kelp can be hung on the first supporting plate and the second supporting plate. When hanging the kelp, the kelp can be directly stuffed between the two inclined blocks through the inclined surfaces of the two inclined blocks and clamped by the two inclined blocks. There is no need to manually pry the two inclined blocks apart, which is very convenient.

[0017] By setting up a rotating mechanism, after the kelp is hung on the first supporting plate and the second supporting plate, the first supporting plate and the second supporting plate are driven to rotate intermittently, so that each piece of kelp on the first supporting plate and the second supporting plate can face the nozzle and be cleaned by the salt water sprayed by the nozzle.

[0018] By setting up a cleaning mechanism, not only can external salt water be transported to spray on the kelp for cleaning, but also external water can be transported to the heating pipe, and the residual temperature in the temperature-controlled air-drying box can be used to heat the water, and the heat in the temperature-controlled air-drying box can be recovered, thereby improving the overall energy-saving effect of the device.

[0019] By providing an adjustment mechanism, the distance between the first supporting plate and the second supporting plate can be adjusted according to the length of the kelp, so as to improve the overall adaptability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] As Figures 1 to 2 shown, the present invention provides an intelligent multi-temperature zone staged temperature-controlled air-drying device for kelp, including a temperature-controlled air-drying box 1 and a track 2 fixedly installed on the top surface of the inner wall of the temperature-controlled air-drying box 1. The track 2 extends to the outside of the temperature-controlled air-drying box 1, and two symmetrically distributed first electric push doors 3 are installed on one side of the temperature-controlled air-drying box 1.

[0037] As Figure 2 、 Figure 3 and Figure 4As shown, a number of sliding rods 41 are slidably connected to the track 2. Each sliding rod 41 is rotatably connected to a first bearing plate 42. A telescopic round rod 43 is vertically fixed to the lower surface of the first bearing plate 42. The lower end of the telescopic round rod 43 is fixedly connected to a second bearing plate 44.

[0038] A number of clamping assemblies are arranged on both the first bearing plate 42 and the second bearing plate 44 in a circumferential array. A rotating mechanism for driving the first bearing plate 42 and the second bearing plate 44 to rotate intermittently, and a cleaning mechanism for spraying brine on the kelp are arranged outside the temperature-controlled air-drying box 1.

[0039] As Figure 5 and Figure 6 shown, the clamping assembly includes two vertical plates 51 vertically fixed to the lower surfaces of the first bearing plate 42 and the second bearing plate 44. Spring rods 52 are fixedly connected to the mutually approaching sides of the two corresponding vertical plates 51. The free ends of the spring rods 52 are fixedly connected to inclined plane blocks 53. The two inclined plane blocks 53 are in contact with each other.

[0040] In use, the kelp can be clamped between the two inclined plane blocks 53, so that the kelp is hung on the first bearing plate 42 and the second bearing plate 44.

[0041] And when hanging the kelp, the kelp can be directly inserted between the two inclined plane blocks 53 through the inclined plane of the two inclined plane blocks 53 and clamped by the two inclined plane blocks 53, without manually separating the two inclined plane blocks 53.

[0042] As Figure 3 , Figure 7 and Figure 8 shown, the rotating mechanism includes a bottom plate 61 fixed to the temperature-controlled air-drying box 1. A vertical plate 62 is vertically fixed to the upper surface of the bottom plate 61. Two symmetrically distributed L-shaped rods 63 are fixedly connected to the surface of the vertical plate 62. A transverse frame 64 is fixedly connected between the two L-shaped rods 63. A U-shaped seat 65 is slidably connected inside the transverse frame 64. A ratchet 66 is rotatably connected to the U-shaped seat 65. A limiting spring 67 is fixedly connected between the ratchet 66 and the inner wall of the U-shaped seat 65. A first gear 68 is integrally formed at the edge of the first bearing plate 42. The ratchet 66 meshes with the first gear 68.

[0043] Adopting the above scheme, when the ratchet 66 reciprocates along the transverse frame 64, it can only drive the first gear 68 and the first bearing plate 42 to rotate intermittently in one direction.

[0044] As Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, a plane plate 69 is slidably connected to the vertical plate 62 in an upper and lower limit manner, a bevel groove 610 is provided on the surface of the plane plate 69, and a slide rod 611 slidably matched with the bevel groove 610 is fixedly connected to the surface of the U-shaped seat 65.

[0045] The flat plate 69 is driven by an external electric push rod.

[0046] By adopting the above solution, when the flat plate 69 is driven by an external electric push rod to reciprocate up and down, the inner wall of the inclined groove 610 can push the slide bar 611 and the U-shaped seat 65 to reciprocate along the transverse frame 64.

[0047] like Figure 1 , Figure 7 and Figure 11 As shown, the cleaning mechanism includes a barrel 71 vertically fixed on the upper surface of the temperature-controlled air-drying box 1, and the surface of the barrel 71 is fixedly connected with a water inlet pipe 72 and a water outlet pipe 73 which are interconnected, a first valve body 74 is installed on the water inlet pipe 72, and a second valve body 75 is installed on the water outlet pipe 73, a water spray pipe 76 is fixedly connected to the surface of the flat plate 69, and two nozzles 77 distributed up and down are installed on the water spray pipe 76, and a heating pipe 78 is arranged in the temperature-controlled air-drying box 1.

[0048] Among them, a hose is installed at one end of the water outlet pipe 73 away from the barrel 71, which is not shown in the figure;

[0049] When it is necessary to absorb external salt water and spray it on the kelp to clean the kelp, the free end of the hose is installed at the lower end of the spray pipe 76;

[0050] When it is necessary to absorb external water source and transport it into the heating pipe 78, the free end of the hose is installed on the heating pipe 78. After the external water source is transported into the heating pipe 78, the residual temperature in the temperature-controlled air drying box 1 can be used to heat the water source, thereby achieving a heat recovery effect.

[0051] The water inlet pipe 72 may be connected to the salt water through an external pipe, or may be connected to a water source to be heated through an external pipe.

[0052] like Figure 10 and Figure 11 As shown, a vertical rod 79 is fixedly connected to the lower surface of the inclined groove 610 , and the lower end of the vertical rod 79 extends into the barrel 71 and is fixedly connected to a circular plate 710 .

[0053] By setting up a clamping assembly, the kelp can be clamped between the two inclined blocks 53, so that the kelp can be hung on the first supporting plate 42 and the second supporting plate 44, and when hanging the kelp, the kelp can be directly stuffed between the two inclined blocks 53 through the inclined surfaces of the two inclined blocks 53, and clamped by the two inclined blocks 53, without manually prying the two inclined blocks 53 apart, which is very convenient.

[0054] By setting up a rotating mechanism, after hanging the kelp on the first bearing plate 42 and the second bearing plate 44, the first bearing plate 42 and the second bearing plate 44 are driven to rotate intermittently, so that each piece of kelp on the first bearing plate 42 and the second bearing plate 44 can face the nozzle 77 and be washed by the brine sprayed out by the nozzle 77.

[0055] By setting up a cleaning mechanism, it can not only transport external brine to spray on the kelp for cleaning the kelp, but also transport external water source into the heating pipe 78, utilize the residual heat in the temperature-controlled air-drying box 1 to complete the heating of water, and recover the heat in the temperature-controlled air-drying box 1, improving the overall energy-saving effect of the device.

[0056] Above the bottom plate 61, an adjusting mechanism is provided for adjusting the distance between the first bearing plate 42 and the second bearing plate 44.

[0057] By setting up an adjusting mechanism, it is convenient to adjust the distance between the first bearing plate 42 and the second bearing plate 44 according to the length of the kelp, so as to improve the overall adaptability of the device.

[0058] As Figure 6 and Figure 14 shown, the adjusting mechanism includes a long rod 91 telescopically inserted at the lower end of the sliding rod 41. A chute 92 is provided on the surface of the long rod 91. The sliding rod 41 is of a hollow structure as a whole, and a rectangular block 93 adapted to the chute 92 is integrally formed at the lower end. The second bearing plate 44 is rotatably connected to the lower end of the long rod 91.

[0059] Adopting the above scheme, only telescoping can occur between the sliding rod 41 and the long rod 91, and rotation is not possible.

[0060] As Figure 12 and Figure 13 shown, a reciprocating threaded rod 94 is rotatably connected inside the sliding rod 41. The upper end of the long rod 91 is sleeved on the reciprocating threaded rod 94, and a slider adapted to the groove on the surface of the reciprocating threaded rod 94 is rotatably connected inside the long rod 91. A bevel gear one 95 coaxially fixed with the reciprocating threaded rod 94 is rotatably connected inside the sliding rod 41. A bevel gear two 96 meshing with the bevel gear one 95 is rotatably connected to the side wall of the sliding rod 41. A second gear 97 coaxially fixed with the bevel gear two 96 is rotatably connected to the outer side wall of the sliding rod 41. An arc-shaped rack 98 is fixed to the lower surface of the first bearing plate 42.

[0061] Among them, the slider inside the long rod 91 is not shown in the figure, and the arc-shaped rack 98 can mesh with the second gear 97.

[0062] As Figure 1 shown, three second electric push doors 8 are installed in the temperature-controlled air-drying box 1.

[0063] In use, the three second electric push doors 8 divide the interior of the temperature-controlled air drying box 1 into four areas, which are area 1, area 2, area 3 and area 4 from the side close to the bottom plate 61 to the side far from the bottom plate 61;

[0064] Among them, the first zone is the preheating stage, with a temperature of 50-55℃ and a high humidity of the kelp. It is mainly to keep the temperature inside and outside the kelp consistent to prevent the formation of a dense film on the surface, which is convenient for the next step of moisture removal.

[0065] The second zone is the balanced dehumidification stage, with a temperature of 55-60℃. The air valve is adjusted to control the wind speed, and weak wind is used to dehumidify the box, keeping the humidity low and gradually removing moisture.

[0066] The third zone is the heating and drying stage, with a temperature of 65-70℃. Adjust the air valve to control the wind speed, and use strong wind to remove moisture and dry.

[0067] The fourth zone is the cooling and shaping stage, with a temperature of 50-55℃. Adjust the air valve to control the wind speed and cool down to avoid deformation due to excessive dehydration.

[0068] The working principle and use process of the present invention:

[0069] First, the kelp is clamped between the two inclined blocks 53, so that the kelp is hung on the first supporting plate 42 and the second supporting plate 44, and when the kelp is hung, the kelp can be directly inserted between the two inclined blocks 53 through the inclined surfaces of the two inclined blocks 53, and the kelp is clamped by the two inclined blocks 53, without manually breaking the two inclined blocks 53 apart;

[0070] When the flat plate 69 is driven to reciprocate up and down by an external electric push rod, the flat plate 69 can push the slide bar 611 and the U-shaped seat 65 to reciprocate along the transverse frame 64 through the inner wall of the inclined groove 610, and the U-shaped seat 65 can drive the ratchet 66 to reciprocate along the horizontal direction, but the ratchet 66 can only drive the first gear 68 and the first bearing plate 42 to intermittently rotate in one direction, and the first bearing plate 42 can drive the second bearing plate 44 to intermittently rotate through the telescopic round rod 43, so that the kelp hanging on the first bearing plate 42 and the second bearing plate 44 also rotates intermittently, so that each piece of kelp on the first bearing plate 42 and the second bearing plate 44 can face the nozzle 77 and be cleaned by the salt water sprayed by the nozzle 77;

[0071] Among them, a hose is installed at one end of the water outlet pipe 73 away from the barrel 71, which is not shown in the figure;

[0072] When it is necessary to absorb external salt water and spray it on the kelp to clean the kelp, the free end of the hose is installed at the lower end of the spray pipe 76;

[0073] Meanwhile, the flat panel 69 can drive the circular plate 710 to move up and down reciprocally through the vertical rod 79. The circular plate 710 can perform a piston motion within the cylindrical barrel 71, sucking external brine into the cylindrical barrel 71 through the water inlet pipe 72, and then spraying it out through the water outlet pipe 73, the hose, the water spray pipe 76, and the nozzle 77 onto the kelp to be cleaned, completing the cleaning work on the kelp;

[0074] When it is necessary to suck external water source and transport it into the heating pipe 78, the free end of the hose is installed on the heating pipe 78. After the external water source is transported into the heating pipe 78, the residual heat in the temperature-controlled air-drying box 1 can be utilized to heat the water source, thereby achieving an effect of heat recovery;

[0075] When it is necessary to adjust the distance between the first bearing plate 42 and the second bearing plate 44, the first bearing plate 42 is driven to rotate. The first bearing plate 42 can drive the arc-shaped rack 98 fixed to its lower surface to rotate accordingly. When the arc-shaped rack 98 meshes with the second gear 97, the arc-shaped rack 98 can drive the second gear 97 to rotate accordingly. The second gear 97 can drive the bevel gear two 96 fixed coaxially with it to rotate accordingly. The bevel gear two 96 can drive the bevel gear one 95 meshing with it to rotate accordingly. The bevel gear one 95 can drive the reciprocating threaded rod 94 fixed coaxially with it to rotate accordingly. The reciprocating threaded rod 94 can drive the long rod 91 to move along the vertical direction. The long rod 91 can drive the second bearing plate 44 to move along the vertical direction accordingly, thereby changing the distance between the first bearing plate 42 and the second bearing plate 44.

[0076] Among them, when cleaning the kelp, the first bearing plate 42 only needs to rotate one circle, and the arc-shaped rack 98 on the lower surface of the first bearing plate 42 will only mesh with the second gear 97 once, which will not have too much impact on the distance between the first bearing plate 42 and the second bearing plate 44.

[0077] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0078] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
