Description

Technical Field

[0001] This utility model relates to the field of screw conveyor technology, and in particular to a double-layer cooling screw integrated machine. Background Technology

[0002] The existing double-layer cooling spiral integrated machine includes two parallel and connected transport shells, two spirals, a cooling jacket, and a drive assembly. The cooling jacket wraps around the outside of the two transport shells, and cooling water flows inside the cooling jacket. The drive assembly drives the two spirals in the transport shells to rotate together. The material enters the upper transport shell from the feed port and is transported by the rotating spirals to the connecting port between the two transport shells. The material then enters the lower transport shell from the connecting port and is transported by the rotating spirals to the discharge port. During the transport process, the material is cooled by rotating and contacting the inner wall of the transport shell. However, the existing upper and lower transport shells use the same cooling medium and flow rate for cooling. In the initial cooling stage of the material with a high temperature, a large temperature difference will cause the material to cool down rapidly, resulting in over-cooling and affecting the quality and performance of the material.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0009] The first cooling jacket is wrapped around the outside of the first cylinder. The first cooling jacket has a first water inlet on the upper side of the first end and a first water outlet on the upper side of the second end.

[0010] The second cooling jacket is wrapped around the outside of the second cylinder. The lower side of the second cooling jacket is connected to the upper side of the first cooling jacket. A second water inlet is opened on the upper side of the first end of the second cooling jacket, and a second water outlet is opened on the upper side of the second end of the second cooling jacket.

The second ends of the two central shafts are respectively connected to two meshing gears in the synchronous gear set, and the second end of one of the central shafts passes through one of the gears and is connected to the output end of the reducer.

[0017] A further technical solution is that an exhaust port is also provided at the second end of the upper side of the first cylinder.

[0018] A further technical solution is that an observation window is provided at the connection between the lower side of the second end of the first cylinder and the upper side of the second end of the second cylinder.

[0019] The beneficial effects of this utility model embodiment are as follows:

[0020] (I) A double-layer cooling spiral integrated machine includes a first cylinder, a second cylinder, two conveying spirals, a first cooling jacket and a second cooling jacket. The material enters the first cylinder from the discharge port, and cooling water is introduced into the first cooling jacket from the first water inlet. The cooling water flows out from the first cooling jacket to the first water outlet. After the cooling water flows in the first cooling jacket, the two conveying spirals rotate, and the conveying spirals transport the material to the connection between the first cylinder and the second cylinder, where it enters the second cylinder. Cooling water is introduced into the second cooling jacket from the second water inlet, and the cooling water flows out from the second cooling jacket to the second water outlet. The cooling water flows in the second cooling jacket, and the conveying spirals transport the material from the second end of the second cylinder to the discharge port to complete the discharge. The two cylinders are equipped with their own separate cooling jackets, and the temperature of the cooling water flowing in the second cooling jacket is lower than that of the cooling water flowing in the first cooling jacket. During the rotation and conveying process, the material is first cooled once by the first cooling jacket and then cooled twice by the second cooling jacket, realizing the gradual cooling of the material, reducing the temperature fluctuation of the material, and making the performance of the material more stable.

[0021] (ii) Furthermore, both the first and second cooling jackets are equipped with horizontally spaced and vertically staggered guide vanes. The vertically staggered guide vanes can generate greater turbulence when the cooling water flows, enhancing the mixing effect of the water flow. The water flow is forced to bypass the edge of the guide vanes, breaking the laminar flow state and promoting the water flow into a turbulent state. Turbulence can improve the heat exchange efficiency between the cooling medium and the object surface, making the cooling more uniform. Attached Figure Description

[0030] Example:

[0031] Figure 1 This is a front view structural diagram of the integrated double-layer cooling spiral machine of this utility model. Figure 1 As shown, a double-layer cooling spiral integrated machine includes a first cylinder 110, a second cylinder 120, two conveying spirals 200, a first cooling jacket 300 and a second cooling jacket 400.

[0032] like Figure 1 As shown, the first cylinder 110 is located on the upper side of the second cylinder 120. The upper side of the first end of the first cylinder 110 is provided with a feed inlet 111, and the lower side of the first end of the first cylinder 110 is provided with a discharge outlet 121. The lower side of the second end of the first cylinder 110 is connected to the upper side of the second end of the second cylinder 120.

[0033] like Figure 1As shown, two conveying spirals 200 are rotatably disposed within the first cylinder 110 and the second cylinder 120, respectively. For example, the conveying spiral 200 includes a central shaft 210 and spiral blades 220, with the spiral blades 220 wound and fixed to the surface of the central shaft 210.

[0034] Figure 2 This is a side view of the integrated double-layer cooling spiral machine of this utility model. Figures 1-2 As shown, a first cooling jacket 300 wraps around the outside of a first cylindrical body 110. A first water inlet 301 is formed on the upper side of the first end of the first cooling jacket 300, and a first water outlet 302 is formed on the upper side of the second end of the first cooling jacket 300. A second cooling jacket 400 wraps around the outside of a second cylindrical body 120. The lower side of the second cooling jacket 400 is connected to the upper side of the first cooling jacket 300. A second water inlet 401 is formed on the upper side of the first end of the second cooling jacket 400, and a second water outlet 402 is formed on the upper side of the second end of the second cooling jacket 400. The temperature of the cooling water flowing inside the second cooling jacket 400 is lower than the temperature of the cooling water flowing inside the first cooling jacket 300. For example, the front and rear sides of the first cooling jacket 300 are respectively connected to the front and rear sides of the first cylindrical body 110, and the first cooling jacket 300 and the outer surface of the first cylindrical body 110 enclose a cavity. The front and rear sides of the second cooling jacket 400 are respectively connected to the front and rear sides of the lower side of the first cooling jacket 300, and the second cooling jacket 400 and the outer surface of the second cylinder 120 enclose a cavity.

[0035] Figure 3 for Figure 1 A magnified view at point A. (See image below.) Figures 1-3 As shown, furthermore, both the first cooling jacket 300 and the second cooling jacket 400 are provided with guide plates 500 spaced apart and staggered vertically along the length of the first cooling jacket 300. Specifically, some guide plates 500 are staggered vertically between the lower side of the first cooling jacket 300 and the upper side of the first cylinder 110, and some guide plates 500 are staggered vertically between the upper side of the second cooling jacket 400 and the lower side of the second cylinder 120. The staggered guide plates 500 can generate greater turbulence when the cooling water flows, enhance the mixing effect of the water flow, force the water flow to bypass the edge of the guide plate 500, break the laminar flow state, and promote the water flow into a turbulent state. Turbulence can improve the heat exchange efficiency between the cooling medium and the object surface, making the cooling more uniform.

[0036] Figure 4 for Figure 2 A magnified view at point B. (See image below.) Figure 2 and Figure 4As shown, furthermore, reinforcing ribs 600 are fixedly connected to the outer sides of the connection between the first cooling jacket 300 and the second cooling jacket 400 on both the front and rear sides. The reinforcing ribs 600 increase the strength and stability of the connection, preventing the cooling jacket from bending or collapsing due to water pressure and other external forces. Especially in high-pressure working environments, the reinforcing ribs 600 can improve the pressure resistance of the cooling jacket.

[0037] like Figure 1 As shown, the second end of the first cylinder 110 is further provided with a drive assembly 700, which includes a synchronous gear set 710 and a reducer 720. The second ends of the two central shafts 210 are respectively connected to two meshing gears in the synchronous gear set 710. The second end of one of the central shafts 210 passes through one of the gears and is connected to the output end of the reducer 720. The synchronous gear set 710 transmits power from the reducer 720 to the two central shafts 210. The power is evenly distributed to the two central shafts 210, causing the central shaft 210 of the first cylinder 110 to rotate clockwise. Material enters the first cylinder 110 and is transported from the first end to the second end of the first cylinder 110. Through the meshing of the two gears, the central shaft 210 of the second cylinder 120 is rotated counterclockwise. Material enters the second cylinder 120 from the connecting point and is transported from the second end to the first end of the second cylinder 120.

[0038] like Figure 1 As shown, a vent 112 is further provided at the second end of the upper side of the first cylinder 110. During the material conveying process, gas may accumulate inside the conveying cylinder, causing uneven conveying and hindering the normal conveying of materials. The function of the vent 112 is to discharge these gases in a timely manner, ensuring the stable conveying of materials and avoiding stagnation or reduced efficiency caused by gas blockage.

[0039] like Figure 1 As shown, furthermore, an observation window 800 is provided at the connection between the lower side of the second end of the first cylinder 110 and the upper side of the second end of the second cylinder 120. The observation window 800 helps to check whether the material flow is uniform. If there is blockage, accumulation or uneven flow of material during the conveying process, the observation window 800 can help to detect these problems early and take appropriate measures to adjust or clear the conveying path.

[0040] In operation, this embodiment is as follows:

[0041] Material enters the first cylinder 110 through the discharge port 121. Cooling water is introduced into the first cooling jacket 300 through the first inlet 301. The cooling water flows out from the first cooling jacket 300 to the first outlet 302. After the cooling water flows in the first cooling jacket 300, the reducer 720 is started. The reducer 720 drives one central shaft 210 to rotate. Through the synchronous gear set 710, the other central shaft 210 rotates synchronously. The spiral blades 220 on the central shaft 210 transport the material to the connection between the first cylinder 110 and the second cylinder 120. The material enters the second cylinder 120. Cooling water is introduced into the second cooling jacket 400 through the second inlet 401. The cooling water flows out from the second cooling jacket 400 to the second outlet 402. The cooling water flows in the second cooling jacket 400. The spiral blades 220 on the central shaft 210 transport the material from the second end of the second cylinder 120 to the discharge port 121 at the second end to complete the discharge.

[0042] In this embodiment, each of the two cylinders is equipped with its own separate cooling jacket, and the temperature of the cooling water flowing in the second cooling jacket 400 is lower than the temperature of the cooling water flowing in the first cooling jacket 300. During the rotational conveying process, the material first passes through the first cooling jacket 300 for a one-time cooling, and then passes through the second cooling jacket 400 for a second-time cooling, thus achieving a step-by-step cooling of the material, reducing the temperature fluctuation of the material, and making the performance of the material more stable.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
