[0033] Furthermore, as Figures 1-4 shown, a filter screen 9 is arranged at the top of the drying box 2, a gauze 10 is arranged inside the drying box 2, a plurality of through holes 11 are opened at the bottom of the drying box 2, a plurality of water outlets 12 are opened on both sides of the drying box 2, water tanks 13 are arranged on both sides of the inner top of the dehydrating device main body 1, the bottom of the water tank 13 is inclined, a drain port 14 is opened on the side of the water tank 13 away from the drying box 2, a rubber plug 15 is arranged inside the drain port 14. The drying box 2 is fixedly connected to the filter screen 9. The drying box 2 is communicated with the water tank 13 through the water outlet 12. The drain port 14 is adapted to the rubber plug 15.

[0035] Furthermore, as Figure 1 and Figure 3As shown in the figure, a rotating disk 16 is provided at the bottom inside the dehydrating device main body 1. A salt tank 17 is provided on the top of the rotating disk 16. Arc-shaped clamping plates 18 are provided on both sides of the salt tank 17.

The arc-shaped clamping plate 18 is elastically connected to the support plate 21 through the fixing spring 20. The arc-shaped clamping plate 18 contacts the salt tank 17.

[0036] During operation, pull the pull rods 19 on both sides to drive the arc-shaped clamping plates 18 to move away from each other, and place the salt tank 17 on the rotating disk 16. Since the arc-shaped clamping plates 18 are elastically connected to the support plates 21 through the fixing springs 20, under the elastic force of the fixing springs 20, the arc-shaped clamping plates 18 are pushed to clamp and fix the salt tank 17. Water can be precipitated faster under high-concentration salt, avoiding manual contact and shortening the dehydration time. The driving motor 26 is started to drive the second bevel gear 25 to rotate. Since the second bevel gear 25 meshes with the first bevel gear 24, under the meshing action of the gears, the first bevel gear 24 drives the rotating disk 16 to rotate, so as to perform centrifugal dehydration during heating dehydration.

[0037] Furthermore, as Figure 1 and Figure 3 shown in the figure, hydraulic cylinders 27 are provided on both sides inside the dehydrating device main body 1. The extending ends of the hydraulic cylinders 27 are connected to a cover plate 28. A plurality of exhaust holes 29 are provided in the inner wall part of the cover plate 28. The exhaust holes 29 are arranged in a circular pattern. A heating plate 30 is provided in the middle of the cover plate 28. An air delivery pipe 31 is provided above the heating plate 30. One end of the air delivery pipe 31 is connected to the heating plate 30. The other end of the air delivery pipe 31 is connected to an air box 32. A filter plate 38 is provided on the right side of the air box 32. A plurality of heating wires 39 are provided inside the air box 32. A plurality of air outlet holes 40 are provided on the left side of the air box 32. The hydraulic cylinders 27 are fixedly connected to the cover plate 28. The heating plate 30 is three-dimensional with the air delivery pipe 31. The air delivery pipe 31 is communicated with the air box 32. The air box 32 is fixedly connected to the heating wires 39 and the filter plate 38 respectively.

[0038] During operation, the hydraulic cylinder 27 is activated to drive the cover plate 28 downward, placing the cover plate 28 above the salt tank 17. The heating fan blades 37 rotate, filtering the air through the filter plate 38, heating it through the heating wire 39, and inputting it into the heating plate 30 through the air delivery pipe 31. The heating plate 30 heats and dehydrates the black pickles inside the salt tank 17. The water removed is heated into water vapor and rises, discharging from the air outlet 40.

[0039] Further, as Figure 1 and Figure 3 shown, a fixed shaft 33 is inserted inside the second bevel gear 25. A first sprocket 34 is sleeved on the right end of the fixed shaft 33. A drive chain 35 is sleeved outside the first sprocket 34. A second sprocket 36 is arranged below the drive chain 35. The output end of the second sprocket 36 is connected to a plurality of heating fan blades 37. The second bevel gear 25 is fixedly connected to the fixed shaft 33.

The second sprocket 36 is fixedly connected to the heating fan blades 37.

[0040] During operation, the second bevel gear 25 drives the first sprocket 34 to rotate under the action of the fixed shaft 33. Since the first sprocket 34 is chain-driven with the second sprocket 36 through the drive chain 35, under the action of friction, the first sprocket 34 pushes the drive chain 35 to move, thereby driving the second sprocket 36 to rotate synchronously, causing the second sprocket 36 to drive the heating fan blades 37 to rotate accordingly, allowing external air to flow into the air box 32.

[0041] Working principle:

[0042] First, place the drying box 2 on the top of the dehydration equipment main body 1 through the mounting block 3. Rotate the mounting screws 8 on both sides. Under the action of the thread, the movable plate 7 can be pulled to move towards each other. Since the fixed insertion rod 5 is fixedly connected to the connecting rod 6, and the connecting rod 6 is fixedly connected to the movable plate 7, under the action of the connecting rod 6, the fixed insertion rod 5 is pushed into the fixed insertion hole 4 to fix the mounting block 3, thus completing the installation and fixation of the drying box 2.

[0043] Secondly, pull the pull rods 19 on both sides to drive the arc-shaped clamping plates 18 to move away from each other, and place the salt tank 17 on the rotating disk 16. Since the arc-shaped clamping plates 18 are elastically connected to the support plate 21 through the fixed springs 20, under the elastic force of the fixed springs 20, the arc-shaped clamping plates 18 are pushed to clamp and fix the salt tank 17. Under high-concentration salt, water can be precipitated faster, avoiding manual contact and shortening the dehydration time. The drive motor 26 is activated to drive the second bevel gear 25 to rotate. Since the second bevel gear 25 meshes with the first bevel gear 24, under the meshing action of the gears, the first bevel gear 24 drives the rotating disk 16 to rotate, thereby performing centrifugal dehydration during heating and dehydration.

[0044] Subsequently, the second bevel gear 25 drives the first sprocket 34 to rotate under the action of the fixed shaft 33. Since the first sprocket 34 is chain-driven with the second sprocket 36 through the drive chain 35, under the action of friction, the first sprocket 34 pushes the drive chain 35 to move, thereby driving the second sprocket 36 to rotate synchronously, causing the second sprocket 36 to drive the heating fan blade 37 to rotate accordingly, and enabling external air to flow into the air box 32;

[0045] Then, the hydraulic cylinder 27 is activated to drive the cover plate 28 to move downward, so that the cover plate 28 is placed above the salt tank 17. The heating fan blade 37 rotates, filters the air through the filter plate 38, heats it through the heating wire 39, and inputs it into the heating plate 30 through the air delivery pipe 31. The heating plate 30 heats and dehydrates the black pickled vegetables inside the salt tank 17. The water dehydrated rises as water vapor and is discharged from the air outlet 40;

[0046] Finally, silica gel desiccant is placed inside the drying box 2. The water vapor enters the drying box 2 through the through holes 11, and the silica gel desiccant absorbs the heated water vapor. After the water vapor absorption is completed, it will fall due to gravity and is discharged into the water tank 13 through the water outlets 12 on both sides. After the dehydration work is completed, the rubber plug 15 is pulled out, and the water inside the water tank 13 is discharged through the drain port 14, so that the air humidity does not reach saturation, and the dehydrated water can be separated from the material, reducing the contact.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
