[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] High-temperature fluid sterilization technology is usually used to treat fluids or high-viscosity fluids. The principle is to use high temperature to sterilize fluid materials. Commonly used equipment includes shell-and-tube heat exchangers, volumetric heat exchangers, etc.

[0037] However, when processing high-viscosity fluids, existing sterilization equipment is affected by the slow flow rate and high viscosity of the high-viscosity fluids, resulting in slow heat transfer and uneven heating of the high-viscosity fluids, which leads to incomplete sterilization of the high-viscosity fluids.

[0038] In the embodiment of the present invention, a drum, a rotating shaft and a fin assembly are provided. The rotation of the rotating shaft drives the fin assembly and the drum to rotate together, so that the material in the drum forms a vortex. While directing the flow upward, the material contacts the hot rotating shaft and fin assembly to fully exchange heat. The first heating assembly and the second heating assembly perform heat exchange on the material twice, fully exchanging heat on the material and further improving the sterilization effect.

[0039] Combine the following Figures 1 to 4 The present invention provides a rotary sterilizing device for high-viscosity fluids, which specifically includes a first shell 1, a drum 2, a second heating assembly 5, and a motor 4. A feed port 11 and a discharge port 12 are provided on the side of the first shell 1, the feed port 11 is provided below the discharge port 12, the drum 2 is provided in the first shell 1, a gap for high-viscosity fluids to flow is provided between the bottom and the side of the drum 2 and the first shell 1, the gap is connected to the feed port 11, a drum inlet 21 is provided at the bottom of the drum 2, a drum outlet 22 is provided at the top of the drum 2, and the drum outlet 22 is connected to the discharge port 12.

[0040] A rotating shaft 3 is provided in the drum 2, and the rotating shaft 3 is connected to the inner wall of the drum 2 through a fin assembly, and the fin assembly is in a spiral upward bending state. A first heating assembly is provided in both the rotating shaft 3 and the fin assembly. Optionally, the first heating assembly can be configured to open a channel in the rotating shaft 3 and the fin assembly, and a high-temperature gas or liquid is passed into the channel to heat the rotating shaft 3 and the fin assembly. A second heating assembly 5 is provided on the outer wall of the first shell 1. Optionally, the second heating assembly 5 is configured to be a resistance wire or a heating tube wound around the outer wall of the first shell 1 to heat the side wall of the first shell 1. A motor 4 is provided at the top of the first shell 1, and an output shaft 41 of the motor 4 is transmission-connected to the rotating shaft 3.

[0041] High-viscosity fluid materials flow into the gap between the side of the drum 2 and the first shell 1 from the feed port 11, and the second heating component 5 heats the side wall of the first shell 1, thereby preheating the material flowing into the gap. The preheated material continues to flow into the gap between the bottom of the drum 2 and the first shell 1, and enters the drum 2 from the drum inlet 21 at the bottom. The motor 4 drives the rotating shaft 3 to rotate, and the rotating shaft 3 is connected to the fin assembly, thereby driving the fin assembly and the drum 2 to rotate together. The material in the drum 2 is driven by the curved fin assembly to form an eddy current to prevent the material in the drum 2 from being blocked, and can also guide the material upward. While guiding the material upward, the material contacts the hot rotating shaft 3 and the fin assembly to fully exchange heat, thereby achieving sufficient sterilization, and then flows out from the drum outlet 22 and the discharge port 12 to complete the sterilization of the material.

[0042] In the embodiment of the present invention, a drum 2, a rotating shaft 3 and a fin assembly are provided. The rotation of the rotating shaft 3 drives the fin assembly and the drum 2 to rotate together, so that the material in the drum 2 forms a vortex. While directing the flow upward, the material contacts the hot rotating shaft 3 and the fin assembly to fully exchange heat. The first heating assembly and the second heating assembly 5 perform heat exchange on the material twice, fully exchanging heat on the material and further improving the sterilization effect.

[0043] In some embodiments of the present invention, a guide assembly is provided in the gap between the side of the drum 2 and the first shell 1, and the guide assembly is used to guide the inflowing high-viscosity fluid. Optionally, the guide assembly includes a guide groove arranged on the inner wall of the first shell 1. As the drum 2 rotates, the material in the gap between the side of the drum 2 and the first shell 1 is driven to flow along the guide groove to prevent material blockage.

[0044] like Figure 3 As shown, in some other embodiments of the present invention, the guide assembly includes a guide plate 6 disposed on the outer wall of the drum 2, and the guide plate 6 is spirally distributed along the central axis of the drum 2, and the spiral direction of the guide plate 6 is counterclockwise downward along the central axis of the drum 2. As the drum 2 rotates, the material in the gap between the side of the drum 2 and the first shell 1 is driven to flow along the guide plate 6 to prevent material blockage.

[0045] like Figure 4 As shown, the second heating assembly 5 includes a second shell 51, which is sleeved on the outside of the first shell 1. A spirally wound heat exchange tube 52 is provided on the inner wall of the second shell 51, and the heat exchange tube 52 is located between the first shell 1 and the second shell 51. The heat exchange tube inlet 521 and the heat exchange tube outlet 522 are arranged on the side of the second shell 51 in the up-down direction. Preferably, the heat exchange tube inlet 521 is arranged at the bottom, and the heat exchange tube outlet 522 is arranged at the top. A high-temperature medium is introduced into the heat exchange tube 52, and the high-temperature medium enters from the heat exchange tube inlet 521 at the bottom and flows out from the heat exchange tube outlet 522 at the top, forming convection with the material flowing into the feed inlet 11, thereby improving the preheating effect.

[0046] like Figure 2 As shown, in some embodiments of the present invention, the fin assembly includes a plurality of fin units, and the plurality of fin units 7 are evenly distributed along the central axis of the rotating shaft 3. Each fin unit 7 includes four fins 7, and the four fins 7 are evenly distributed along the circumference of the rotating shaft 3, and each fin 7 is spirally bent upward. The rotating shaft 3 rotates, driving the fins 7 to rotate, and the material in the drum 2 is driven by the curved fins 7 to form a vortex, which prevents the material in the drum 2 from being blocked and can also guide the material upward.

[0047] In some other embodiments of the present invention, the first heating assembly includes heating pipes, which are evenly distributed in the rotating shaft 3 and each fin 7. High-temperature gas or liquid can be passed into the heating pipe as a heat exchange medium, or the first heating assembly adopts other existing structures that can heat the rotating shaft 3 and the fin 7.

[0048] like Figure 2 As shown, in some embodiments of the present invention, a partition 8 is provided in the first shell 1, and the partition 8 divides the inner cavity of the first shell 1 into an upper cavity and a lower cavity. The drum 2 is arranged in the lower cavity, and the drum outlet 22 and the discharge port 12 are both connected to the upper cavity. The material in the drum 2 flows upward as the rotating shaft 3 rotates, enters the upper cavity from the drum outlet 22, and then flows out from the discharge port 12.

[0049] In order to buffer the material flowing from the drum 2 into the upper cavity, in some embodiments of the present invention, Figure 2 As shown, the drum outlet 22 is conical, specifically including a first conical outlet 221 expanding from the partition 8 toward the inside of the drum 2 and a second conical outlet 222 expanding from the partition 8 toward the upper cavity, that is, the drum outlet 22 passes through the partition 8, and a hole is provided in the center of the partition 8 for the drum outlet 22 to pass through. The material in the drum 2 flows toward the second conical outlet 222 under the guidance of the first conical outlet 221, and then enters the upper cavity.

[0050] In order to prevent the material in the upper cavity from flowing into the lower cavity through the gap between the partition 8 and the drum outlet 22, an annular baffle 9 is further provided on the top of the partition 8. The baffle 9 is coaxially arranged with the drum 2. The baffle 9 is sleeved on the outside of the drum outlet 22, that is, it is sleeved on the outside of the hole opened in the center of the partition 8 for the drum outlet 22 to pass through, and the baffle 9 should be higher than the partition 8 by a certain distance, but cannot interfere with the second conical outlet 222.

[0051] In some other embodiments, the outer edge of the second conical outlet 222 is connected to the annular buffer plate 23 , and the buffer plate 23 guides the material in the second conical outlet 222 and plays a buffering role.

[0052] like Figure 1 As shown, in some embodiments of the present invention, the bottom of the motor 4 is connected to the top of the first housing 1 through the first support column 42. The rotary sterilizing device also includes a base 10, which is connected to the bottom of the first housing 1 through a second support column 101.
