[0030] See also Figure 3-Figure 5 In this embodiment, the first winding section 304, the partition section 303, and the second winding section 305 are a flat steel plate 5 before winding. After the steel plate 5 is bent, the first winding section 304, the partition section 303, and the second winding section 305 are formed. Specifically, the bending process of the steel plate 5 is as follows:

[0031] S1. Bend the steel plate 5 for the first time at the middle position in the length direction of the steel plate 5 so that the steel plate 5 forms a first winding section 304 and a section to be bent, and the section to be bent and the first winding section 304 are perpendicular to each other.

[0032] S2. Bend the section to be bent for the second time, so that the section to be bent forms a partition section 303 and a second winding section 305, the partition section 303 is perpendicular to the first winding section 304 and the second winding section 305, and the first winding section 304 is located on one side of the partition section 303, and the second winding section 305 is located on the other side of the partition section 303, that is, the first winding section 304 and the second winding section 305 extend in opposite directions on both sides of the partition section 303.

[0033] S3. Use a bending machine to apply torque at the center line of the partition segment 303 in the width direction, so that the partition segment 303 drives the first winding segment 304 and the second winding segment 305 to wind in the same direction, thereby forming the spiral retainer 3.

[0034] See also Figure 2 , wherein the area formed between the starting part of the first winding section 304 and the partition section 303 during the winding process is the first outlet 3012, and the area formed between the starting part of the second winding section 305 and the partition section 303 during the winding process is the second inlet 3021. Moreover, after the winding is completed, the area between the inner side wall of the first winding section 304 and the outer side wall of the second winding section 305 is the first spiral flow channel 301, and the area between the outer side wall of the first winding section 304 and the inner side wall of the second winding section 305 is the second spiral flow channel 302. The area formed between the inner side wall of the end of the first winding section 304 and the outer side wall of the second winding section 305 is the first inlet 3011, and the area formed between the inner side wall of the end of the second winding section 305 and the outer side wall of the first winding section 304 is the second outlet 3022.

[0035] After the winding is completed, the two axial end faces of the spiral retainer 3 are sealed respectively, that is, sealing fillers (not shown in the figure) are respectively filled in the openings of each spiral flow channel on the two axial end faces of the spiral retainer 3, and then welding is performed on the sealing fillers to fill the openings of each spiral flow channel with solder, thereby achieving sealing, and welding a first sealing plate (not shown in the figure) at the two ports of the first outlet 3012 for sealing, and welding a second sealing plate (not shown in the figure) at the two ports of the second inlet 3021 for sealing.

[0036] See also Figure 3-Figure 5In this embodiment, a plurality of support members 4 are respectively provided in the first spiral flow channel 301 and the second spiral flow channel 302, and the plurality of support members 4 are distributed in a dot matrix. One end of the support member 4 is fixedly connected to the first winding section 304 or the second winding section 305, so that the support member 4 is fixed in the first spiral flow channel 301 and the second spiral flow channel 302. The support member 4 can limit the flow channel spacing between the first spiral flow channel 301 and the second spiral flow channel 302, so that the cross-sectional area of ​​the flow channel portion of the first spiral flow channel 301 excluding the first outlet 3012 and the cross-sectional area of ​​the flow channel portion of the second spiral flow channel 302 excluding the second inlet 3021 are equal.

[0037] See also Figure 3-Figure 5 It should be noted that the support member 4 is fixedly connected to the steel plate 5 in advance, that is, before the steel plate 5 is bent and wound, one end of the support member 4 is fixedly connected to the steel plate 5, and the other end extends in a direction away from the steel plate 5. Specifically, the support members 4 are welded on the first winding section 304 and located on the front side of the steel plate 5 and on the second winding section 305 and located on the back side of the steel plate 5, respectively. The support members 4 are distributed in a dot matrix on each plate surface of the steel plate 5. When winding, the first spiral flow channel 301 and the second spiral flow channel 302 with a certain flow channel spacing can be formed by the restriction of the support members 4.

[0038] See also Figure 3-Figure 5 In this embodiment, a plurality of flow holes 3031 are provided on the partition section 303, and the flow holes 3031 penetrate the partition section 303. The plurality of flow holes 3031 are used to connect the first outlet 3012 of the first spiral flow channel 301 with the second inlet 3021 of the second spiral flow channel 302. The sum of the cross-sectional areas of the plurality of flow holes 3031 is equal to the cross-sectional area of ​​the flow channel portion of the second spiral flow channel 302 excluding the second inlet 3021. With such a configuration, the speed at which the material enters the second spiral flow channel 302 from the first spiral flow channel 301 and the change in the flow rate per unit time are small, thereby improving the stability of the material flow.

[0039] See also Figure 2 In this embodiment, the material outlet 2 includes a first extension channel 201 and a discharge pipe 202. One side of the first extension channel 201 is connected to the second outlet 3022, and the discharge pipe 202 is connected to the side of the first extension channel 201 away from the second outlet 3022. In order to improve the smoothness of the material outflow, the first extension channel 201 smoothly transitions between the inner side wall of the spiral retainer 3 and the inner side wall of the end of the second winding section 305, and the first extension channel 201 and the second winding section 305 are integrally formed, that is, the first extension channel 201 is also a part of the above-mentioned steel plate 5.

[0040] See also Figure 1 and Figure 2, reserve the length of the first extension channel 201 at the end of the second winding section 305, and then bend both sides of the reserved steel plate 5 so that the bent part fits the outer wall of the spiral retainer 3, and then weld the bent part to the outer wall of the spiral retainer 3 to form the first extension channel 201. At this time, the width of the first extension channel 201 gradually decreases in the direction away from the second outlet 3022, and the discharge pipe 202 is connected to the end face of the first extension channel 201 with the smallest width.

[0041] See also Figure 1 and Figure 2 In this embodiment, the material inlet 1 includes a second extension channel 101 and a feed pipe 102. One side of the second extension channel 101 is connected to the first inlet 3011, and the feed pipe 102 is connected to the side of the second extension channel 101 away from the first inlet 3011. In order to improve the smoothness of the material entering, the second extension channel 101 smoothly transitions between the inner side wall of the spiral retainer 3 and the inner side wall of the end of the first winding section 304, and the second extension channel 101 is integrally formed with the first winding section 304, that is, the second extension channel 101 is also a part of the above-mentioned steel plate 5.

[0042] See also Figure 1 and Figure 2 , reserve the length of the second extension channel 101 at the end of the first winding section 304, and then bend both sides of the reserved steel plate 5 so that the bent part fits the outer wall of the spiral retainer 3, and then weld the bent part to the outer wall of the spiral retainer 3 to form the second extension channel 101. At this time, the width of the second extension channel 101 gradually decreases in the direction away from the first inlet 3011, and the feed pipe 102 is connected to the end face of the second extension channel 101 with the smallest width.

[0043] The working principle of the maintainer for biological sterilization of the utility model:

[0044] The material to be sterilized enters the second extension channel 101 through the feed pipe 102, and is guided by the second extension channel 101, and smoothly enters the first spiral channel 301 through the first inlet 3011, and enters the area of ​​the first outlet 3012 through the first spiral channel 301, and then enters the area of ​​the second inlet 3021 under the guidance of the flow hole 3031. Then, under the guidance of the second spiral channel 302, the material smoothly enters the first extension channel 201 through the second outlet 3022, and finally flows out through the discharge pipe 202.

[0045] During the flow of the above-mentioned material, since the first spiral flow channel 301 and the second spiral flow channel 302 are alternately arranged, the flow direction of the material in the first spiral flow channel 301 is opposite to the flow direction of the material in the second spiral flow channel 302. Therefore, the material entering first can complement the temperature of the material entering later, thereby reducing the possibility of a decrease in the material temperature.

[0046] The setting of the partition section 303, on the one hand, enables the spiral retainer 3 to form a double helix structure having a first spiral flow channel 301 and a second spiral flow channel 302 with only one winding, and on the other hand, can form a barrier at the intersection of the first spiral flow channel 301 and the second spiral flow channel 302 to reduce the possibility of turbulence and impact of the material at the intersection.

[0047] The first spiral channel 301 and the second spiral channel 302 are arranged concentrically. The material first passes through the first spiral channel 301, then passes through the second spiral channel 302, and finally flows out. The two spiral channels can realize a longer material travel path while occupying a small area. At the same time, the first spiral channel 301 and the second spiral channel 302 are both spiral structures, and the first extension channel 201 is in a smooth transition from the inner side wall of the spiral retainer 3 to the inner side wall of the end of the second winding section 305, and the second extension channel 101 is in a smooth transition from the inner side wall of the spiral retainer 3 to the inner side wall of the end of the first winding section 304. Therefore, the material is subject to less resistance during the flow process, which reduces the possibility of the material being impacted and improves the stability of the material during the movement process.

[0048] Moreover, the first spiral flow channel 301 and the second spiral flow channel 302 have a larger cross-sectional area than the pipes in the tubular temperature maintenance unit in the prior art, and can transport more materials per unit time, thereby improving the material transportation efficiency. At the same time, a piece of steel plate is used for winding, and the manufacturing cost is low, thereby reducing the manufacturing cost of the entire device.

The same or similar parts between the embodiments can be referred to each other. For the method disclosed in the embodiment, since it corresponds to the device disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the device part description.

This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of ​​the utility model.
