[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0030] The up and down directions described in the present invention refer to Figure 1 The up and down directions in .

There are at least three supports 20, and the supports 20 are evenly distributed along the axis of the tank body 10. In this embodiment, there are four supports 20; the liquid inlet pipe 30 is connected to the bottom of the tank body 10; the liquid outlet pipe 40 is connected to the top of the tank body 10; the support assembly 50 is arranged in the middle of the tank body 10; the spiral plate 60 is wound around the support assembly 50 and spirally extends outward; the sealing assembly plays a sealing role.

[0032] The support assembly 50 includes a partition and a support ring. The partition is located in the middle of the support assembly 50. The partition includes a first partition 5011 and a second partition 5012. The first partition 5011 and the second partition 5012 are arranged in parallel and at intervals. The support ring is semicircular. The support ring includes a first support ring 5021 and a second support ring 5022. There are multiple first support rings 5021. These first support rings 5021 are arranged at intervals along the up and down directions on the surface of the first partition 5011 away from the second partition 5012. There are multiple second support rings 5022. These second support rings 5022 are arranged at intervals along the up and down directions on the surface of the second partition 5012 away from the first partition 5011. The first support ring 5021 is welded to the first partition 5011, and the second support ring 5022 is welded to the second partition 5012, so that the support assembly 50 constitutes two semicircular frames arranged at intervals.

[0033] The middle part of the spiral plate 60 is arranged between the first partition plate 5011 and the second partition plate 5012, and is welded to the first partition plate 5011 and the second partition plate 5012. One end of the spiral plate 60 bypasses the first support ring 5021 and extends spirally outward to form an outer spiral plate 601, and the other end of the spiral plate 60 bypasses the second support ring 5022 and extends spirally outward to form an inner spiral plate 602. The cross-section of the outer spiral plate 601 is spiral, and the cross-section of the inner spiral plate 602 is spiral. The outer spiral plate 601 and the inner spiral plate 602 are arranged at intervals when extending spirally outward. The outer wall of the adjacent outer spiral plate 601 and the inner wall of the inner spiral plate 602 form a first flow channel 603, and the inner wall of the adjacent outer spiral plate 601 and the outer wall of the inner spiral plate 602 form a second flow channel 604, so that the first flow channel 603 and the second flow channel 604 are independent of each other and extend spirally outward.

[0034] The sealing assembly includes a sealing semicircular plate 701, a sealing plate and a sealing steel strip 703, wherein the sealing semicircular plate 701 is located on the outside of the tank body 10, and the cross-section of the sealing semicircular plate 701 is an arc shape. One end of the sealing semicircular plate 701 is welded to the end of the outer spiral plate 601, and the other end of the sealing semicircular plate 701 is welded to the outer wall of the outermost outer spiral plate 601, and a connecting cavity 7011 is formed inside the sealing semicircular plate 701, and the end of the inner spiral plate 602 extends into the connecting cavity 7011, so that the first flow channel 603 and the second flow channel 604 are connected through the connecting cavity 7011; the sealing plate includes an upper sealing plate 7021 located on the upper side of the partition and a lower sealing plate 7022 located on the lower side of the partition, The sealing plate 7021 and the lower sealing plate 7022 are respectively welded to the upper and lower ends of the partition plate, and the sealing plate is also welded to the inner wall of the innermost spiral plate 60. The sealing steel strip 703 is located at the upper and lower ends of the spiral plate 60 and between the outer spiral plate 601 and the inner spiral plate 602. The sealing steel strip 703 is welded to the outer spiral plate 601 and the inner spiral plate 602, so that the upper and lower sides of the first flow channel 603 and the second flow channel 604 are sealed. Of course, in order to better seal the upper and lower sides of the first flow channel 603 and the second flow channel 604, one end of the sealing steel strip 703 is welded to the sealing plate, and the other end of the sealing steel strip 703 is welded to the upper and lower ends of the sealing semicircular plate 701.

[0035] The liquid inlet pipe 30 passes through the lower sealing plate 7022 and is welded to the lower sealing plate 7022, so that the liquid inlet port 31 of the liquid inlet pipe 30 is connected to the first flow channel 603, and the liquid outlet pipe 40 passes through the upper sealing plate 7021 and is welded to the upper sealing plate 7021, so that the liquid outlet port 41 of the liquid outlet pipe 40 is connected to the second flow channel 604. After the fluid enters from the liquid inlet port 31, it flows out from the liquid outlet port 41 after passing through the first flow channel 603, the connecting cavity 7011, and the second flow channel 604, thereby slowing down the flow speed of the fluid, extending the flow distance and sterilization time of the fluid, and is suitable for assembly line production.

[0036] Since the fluid in the connecting cavity 7011 needs to be reversed, the impact on the sealing semicircular plate 701 is large, which may easily cause the welding between the sealing semicircular plate 701 and the end of the outer spiral plate 601 and the outer wall of the outermost outer spiral plate 601 to loosen, causing leakage. In order to slow down the flow rate of the fluid in the connecting cavity 7011, thereby slowing down the impact force on the sealing semicircular plate 701, the openings connecting the first flow channel 603 and the second flow channel 604 with the connecting cavity 7011 are preferably gradually enlarged. In order to control the amplitude of the gradual enlargement of the above-mentioned openings, preferably, a first distance column 6031 is provided at the end of the first flow channel 603 close to the connecting cavity 7011, and the two ends of the first distance column 6031 are respectively welded to the outer wall of the outer spiral plate 601 and the inner wall of the inner spiral plate 602. The first distance column 6031 There are multiple first distance columns 6031, which are arranged at intervals. The closer the first distance column 6031 is to the connecting cavity 7011, the longer its length is. The ratio of the length of the longest first distance column 6031 to the shortest first distance column 6031 is 1.3-1.5; a second distance column 6041 is arranged at the end of the second flow channel 604 close to the connecting cavity 7011, and the two ends of the second distance column 6041 are respectively welded to the inner wall of the outer spiral plate 601 and the outer wall of the inner spiral plate 602. There are multiple second distance columns 6041, which are arranged at intervals. The closer the second distance column 6041 is to the connecting cavity 7011, the longer its length is. The ratio of the length of the longest second distance column 6041 to the shortest second distance column 6041 is 1.4-1.6.

[0037] In order to improve the strength of the tank body 10, the tank body 10 also includes a reinforcing plate, which includes a common reinforcing plate 101 wrapped on the outer wall of the outermost outer spiral plate 601 and a thickened reinforcing plate 102 wrapped on the outer wall of the sealing semicircular plate 701. The thickness of the common reinforcing plate 101 is 1.5-2 times the thickness of the outer spiral plate 601, and the thickness of the thickened reinforcing plate 102 is 3.5-4 times the thickness of the outer spiral plate 601. In order to enhance the reinforcing effect of the reinforcing plate, the common reinforcing plate 101 is welded to the outer wall of the outermost outer spiral plate 601. In this case, one end of the sealing semicircular plate 701 is welded to the end of the common reinforcing plate 101, the outer wall of the common reinforcing plate 101 of the sealing semicircular plate 701 is welded, the thickened reinforcing plate 102 is welded to the outer wall of the sealing semicircular plate 701, and the two ends of the thickened reinforcing plate 102 are also overlapped and welded to the outer wall of the common reinforcing plate 101.

[0038] In order to maintain the stability of the shapes of the first support ring 5021 and the second support ring 5022 when the spiral plate 60 passes around the first support ring 5021 and the second support ring 5022, preferably, a support rod 503 is also provided inside the first support ring 5021 and the second support ring 5022, and the support rod 503 extends in the up and down directions. The support rod 502 is welded and connected to the first support ring 5021 and the second support ring 5022, so that multiple first support rings 5021 are connected as a whole, and multiple second support rings 5022 are connected as a whole, thereby enhancing the stability of the first support ring 5021 and the second support ring 5022. In this embodiment, the support rod 503 is located at the two ends of the inner arc segment of the first support ring 5021 and the second support ring 5022.

[0039] In order to facilitate the connection of external pipelines, a flange 32 is welded to the pipe opening of the liquid inlet pipe 30 close to the liquid inlet 31 , and a flange 42 is welded to the pipe opening of the liquid outlet pipe 40 close to the liquid outlet 41 .

[0040] Compared with the prior art, the present invention has the following advantages:

[0041] The spiral plate single-channel device for fluid sterilization provided by the present invention has a middle portion of the spiral plate passed between two partitions of a supporting assembly, and the end of the spiral plate is allowed to bypass the supporting ring of the supporting assembly and then extend outward in a spiral manner to form a mutually independent first channel and a second channel. The upper and lower ends of the spiral plate are sealed by a sealing assembly, so that the upper and lower sides of the first channel and the second channel are sealed. The end and outer wall of the outer spiral plate are connected by a sealing semicircular plate in the sealing assembly to form a connecting cavity connecting the first channel and the second channel. Then, the inlet / outlet of the inlet / outlet pipe is connected to the first / second channel, so that the fluid enters from the inlet and flows out from the outlet through the first channel, the connecting cavity, and the second channel, thereby slowing down the flow speed of the fluid, prolonging the flow distance and sterilization time of the fluid, and being suitable for assembly line production.
