[0027] See also Figure 2 In this embodiment, the retainer body 1 has a spiral flow channel 101, the end of the spiral flow channel 101 located in the center area of the retainer body 1 is the starting end, and the end of the spiral flow channel 101 located outside the retainer body 1 is the end.
[0028] See also Figure 2 , an isolation plate 102 is provided in the center area of the retainer body 1, one side of the isolation plate 102 is connected to the starting end of the spiral flow channel 101, and the other side is fixedly connected to the inner side wall of the center area of the retainer body 1 by welding. Among them, the isolation plate 102 and the starting end of the spiral flow channel 101 are integrally formed, that is, the isolation plate 102 and the spiral flow channel 101 are wound by a piece of steel plate. A welding bevel is provided on the side of the isolation plate 102 away from the starting end of the spiral flow channel 101, and the side of the isolation plate 102 away from the starting end of the spiral flow channel 101 is fixedly connected to the inner side wall of the center area of the retainer body 1 by welding, and the above-mentioned welding bevel is the area for accommodating solder.
[0029] See also Figure 2 In this embodiment, the isolation plate 102 divides the center area of the retainer body 1 into a first area 103 and a second area 104, and the second area 104 is connected to the spiral flow channel 101. A first sealing plate (not shown in the figure) is fixedly connected to the two ports of the first area 103, and a second sealing plate (not shown in the figure) is fixedly connected to the two ports of the second area 104. The first sealing plate and the second sealing plate are located on the two end surfaces of the retainer body 1 in the axial direction.
[0030] See also Figure 2 and Figure 3In this embodiment, a liquid transfer hole 1021 is provided on the isolation plate 102, and the liquid transfer hole 1021 is used to connect the first area 103 and the second area 104. A plurality of liquid transfer holes 1021 are provided on the isolation plate 102, and the sum of the cross-sectional areas of the plurality of liquid transfer holes 1021 is equal to the cross-sectional area of the spiral flow channel 101. With such an arrangement, the speed at which the material enters the second area 104 from the first area 103 and the change in the flow rate per unit time are small, thereby improving the stability of the material flow.
[0031] See also Figure 2 and Figure 3 In this embodiment, the retainer body 1 includes a winding steel plate 4. Specifically, the isolation plate 102 and the spiral flow channel 101 are formed by winding the winding steel plate 4 starting from one end thereof. The winding process of the winding steel plate 4 is as follows:
[0032] S1. After selecting the area corresponding to the isolation plate 102 at one end of the steel plate in the length direction, the coiled steel plate 4 is bent for the first time so that the steel plate forms the isolation plate 102 and the section to be coiled. At this time, the section to be coiled and the isolation plate 102 are perpendicular to each other.
[0033] S2. Use a bending machine to apply torque to the isolation plate 102 so that the isolation plate 102 drives the winding steel plate 4 to wind. When all the winding steel plates 4 are completed, the retainer body 1 is formed.
[0034] In this embodiment, the sealing component is arranged in the spiral opening on the two end faces of the retainer body 1 in the axial direction. Specifically, the sealing component includes a sealing filler (not shown in the figure) and a sealing solder (not shown in the figure). The sealing filler is made of a metal material such as steel or iron, and its shape is adapted to the spiral openings of each flow channel of the spiral flow channel 101. The sealing filler is arranged in the spiral openings of each flow channel of the spiral flow channel 101, and the side wall of the sealing filler fits the inner side wall of the spiral opening, and the sealing filler is only located at the opening. The sealing solder is fixed to the sealing filler by welding, and the sealing solder is also fixedly connected to the inner side wall of the spiral opening by welding at the same time. Through the cooperation of the sealing filler and the sealing solder, the sealing of the spiral openings on the two end faces of the retainer body 1 in the axial direction is achieved, so that the spiral flow channel 101 can only enter and exit through the feed pipe 2 and the discharge assembly 3.
[0035] See also Figure 2 and Figure 3 In this embodiment, each flow channel of the spiral flow channel 101 except the first area 103 and the second area 104 is provided with a plurality of distance members 5 ( Figure 2(not shown), a plurality of distance pieces 5 are distributed in a dot matrix. One end of the distance piece 5 is fixedly connected to the area of the winding steel plate 4 excluding the isolation plate 102, so that the distance piece 5 is fixed in each flow channel of the spiral flow channel 101 excluding the first area 103 and the second area 104. The distance piece 5 can limit the flow channel spacing of the spiral flow channel 101 excluding the first area 103 and the second area 104, so that the cross-sectional areas of each flow channel of the spiral flow channel 101 excluding the first area 103 and the second area 104 are equal.
[0036] See also Figure 2 and Figure 3 It should be noted that the distance piece 5 is fixedly connected to the winding steel plate 4 in advance, that is, before the winding steel plate 4 is bent and wound, one end of the distance piece 5 is fixedly connected to the winding steel plate 4, and the other end extends in a direction away from the winding steel plate 4. When winding, the flow channel with a certain flow channel spacing can be formed by the restriction of the distance piece 5.
[0037] See also Figure 2 and Figure 3 In this embodiment, the feed pipe 2 is connected to the first sealing plate at any end of the first area 103 so that the feed pipe 2 is in communication with the first area 103. The discharge assembly 3 is connected to the opening corresponding to the end of the spiral flow channel 101 so that the discharge assembly 3 is in communication with the spiral flow channel 101, wherein the discharge assembly 3 includes a transition channel 301 and a discharge pipe 302. One side of the transition channel 301 is in communication with the opening corresponding to the end of the spiral flow channel 101, and the discharge pipe 302 is in communication with the side of the transition channel 301 away from the end of the spiral flow channel 101. In order to improve the smoothness of the material outflow, the transition channel 301 smoothly transitions with the inner side wall of the inner side wall of the end of the spiral flow channel 101, and the transition channel 301 is integrally formed with the winding steel plate 4, that is, the transition channel 301 is also a part of the winding steel plate 4.
[0038] See also Figure 2 and Figure 3 , reserve the length of the transition channel 301 at the end of the wound steel plate 4, then bend both sides of the reserved part of the wound steel plate 4 so that the bent part fits the outer wall of the retainer body 1, and then weld the bent part to the outer wall of the retainer body 1 to form a transition channel 301. At this time, the width of the transition channel 301 gradually decreases in the direction away from the end of the spiral flow channel 101, and the discharge pipe 302 is connected to the end face of the transition channel 301 with the smallest width.
[0039] The working principle of the continuous sterilization maintenance device of the utility model:
[0040] The material to be sterilized enters the first area 103 through the feed pipe 2, and under the guidance of the liquid transfer hole 1021, the material enters the second area 104, and then, under the guidance of the spiral flow channel 101, the material smoothly passes through the transition channel 301 and flows out through the discharge pipe 302. The setting of the isolation plate 102 can form a barrier in the center area of the spiral flow channel 101 to reduce the possibility of turbulence and impact of the material at the intersection, and further improve the stability of the material flow.
[0041] The spiral flow channel 101 is a spiral structure, and the transition channel 301 smoothly transitions between the inner wall of the retainer body 1 and the inner wall of the end of the spiral flow channel 101. Therefore, the material encounters little resistance during the flow process, which reduces the possibility of the material being impacted and improves the stability of the material during the movement.
[0042] Moreover, the spiral channel 101 has a larger cross-sectional area than the conveying pipe in the prior art, and can convey more materials per unit time, thereby improving the material conveying efficiency. At the same time, it is wound with a piece of steel plate, 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.
