[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] Example 1

[0040] The embodiment of the present application discloses a folding plate dryer and a drying device thereof.

[0041] like Figure 1-4 As shown, a folding plate dryer includes a bottom plate 1, a drying sheet arranged on the bottom plate 1, a top plate 3 arranged at the upper end of the drying sheet, a liquid discharge port 5 arranged at the center of the bottom plate 1 and penetrating the bottom plate 1, and an air outlet 4 arranged at the center of the top plate 3 and penetrating the top plate 3.

[0042] The diameter of the bottom plate 1 is smaller than that of the top plate 3 ; the diameter of the liquid discharge port 5 is smaller than that of the gas outlet 4 .

[0043] The diameter of the bottom plate is smaller than that of the top plate, which can effectively ensure that the steam from the bottom to the top can flow upward from the outside of the bottom plate to the outside of the drying sheet, and finally enter the drying sheet and be discharged from the outlet at the center of the top plate.

[0044] The drying sheet is composed of a plurality of folding sheets 2 and a plurality of hooking grooves 6 arranged on the folding sheets 2 .

[0045] A steam passage connecting the inside and the outside is formed between any two adjacent folds 2.

[0046] The steam duct is the channel for steam circulation. The smooth flow of the steam duct can ensure the circulation effect of steam.

[0047] The number of the folding pieces 2 is at least four, and the folding pieces 2 are bent at any angle at least seven times.

[0048] The purpose of setting up multiple flaps is to build more steam channels, which can make fuller use of space and better remove moisture from steam. The purpose of bending the flaps is to form curved steam channels, which can turn the steam flowing inside many times. Due to the different gravity of gas and water, the heavier water can be effectively moved closer to the outer wall under the action of centrifugal force at the bend of the steam channel, and finally captured by the hook groove to form a liquid film, thereby achieving the purpose of reducing the water content in the steam.

[0049] The above-mentioned number of folds and the number of times the folds are bent are both preferred values. When the product volume is large, the number of folds and the number of times the folds are bent can be adjusted as needed. Therefore, changing the number of folds or the number of times the folds are bent should also be included in the protection scope of this application.

[0050] The hook groove 6 is vertically arranged at the bending part of the folding piece 2, and the opening of the hook groove 6 faces the outside of the steam channel; the top of the hook groove 6 abuts against the lower side of the top plate 3, and the bottom of the hook groove 6 does not contact the bottom plate 1.

[0051] The hook wall groove can effectively capture the moisture in the steam. The captured moisture will gather in the hook wall groove in liquid state and flow downward along the hook wall groove under the action of gravity, so as to gather on the bottom plate. The moisture gathered on the bottom plate will flow to the liquid discharge port driven by the steam and finally be discharged from the liquid discharge port.

[0052] The purpose of the hook wall groove not contacting the bottom plate is to facilitate the flow of liquid and avoid the bottom of the hook wall groove hindering the advancement of the liquid. The spacing between the bottom of the hook wall groove and the bottom plate can be controlled at 20mm-100mm.

[0053] The bottom plate 1 is also provided with a terminal drainage groove 7 , the opening of which faces the steam channel; one end of the terminal drainage groove 7 is connected to the end of the outermost flap 2 , and the other end is against the liquid discharge port 5 .

[0054] The setting of the end drainage groove can better guide the water, so that the gathered water can be smoothly sent to the liquid discharge port.

[0055] Example 2

[0056] like Figure 5-7 As shown, the folding plate dryer is composed of a plurality of drying units that can be spliced ​​into a circle; the drying unit is composed of a bottom plate 1, a drying sheet arranged on the bottom plate 1, a top plate 3 arranged at the upper end of the drying sheet, a liquid discharge port 5 arranged at the center position of the splicing of the bottom plate 1 and penetrating the bottom plate 1, and an air outlet 4 arranged at the center position of the splicing of the top plate 3 and penetrating the top plate 3; the drying sheet is composed of a plurality of folding sheets 2, and a plurality of hook wall grooves 6 arranged on the folding sheets 2.

[0057] Two adjacent drying units are separated by the end section of the outermost flap 2 of any drying unit.

[0058] Due to the limitations of transportation and production costs, the transportation cost and production cost of the product can be further reduced by setting up a drying unit.

[0059] It should be noted that a single drying unit can still achieve the drying effect after being combined with the corresponding structure. The principle is the same as that described in the above-mentioned embodiment 1. Therefore, splitting the product and using a single drying unit separately should also be included in the protection scope of this application.

[0060] Example 3

[0061] like Figure 8 As shown, a drying device based on a folding plate dryer includes a cylindrical drying cylinder 8, a folding plate dryer arranged inside the drying cylinder 8, a steam inlet 9 arranged on the drying cylinder 8 and connected to the inside of the drying cylinder 8, a drainage pipe 10 passing through the drying cylinder 8, and an exhaust port 11 arranged on the drying cylinder 8 and connected to the inside of the drying cylinder 8; the diameter of the top plate 3 of the folding plate dryer is the same as the inner diameter of the drying cylinder 8, and the liquid discharge port 5 of the folding plate dryer is connected to the drainage pipe 10.

[0062] When in use, steam is fed into the dryer through the steam inlet. After passing through the folding plate dryer, the water in the steam will be discharged from the drain pipe through the liquid discharge port, while the dried steam will be discharged from the folding plate dryer through the air outlet and finally discharged from the drying device through the exhaust port.

[0063] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0064] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the present invention, and these solutions also belong to the disclosure scope of the present invention and fall within the protection scope of the present invention.
