Through reasonable structural design, these devices achieve efficient cooling of high-temperature materials, ensuring the stability of PVC heat stabilizer performance and the smooth operation of the production process. However, commonly used cooling devices for PVC heat stabilizer production may experience localized overheating during use. Therefore, a new type of cooling device for PVC heat stabilizer production is needed. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a cooling device for PVC heat stabilizer production, thereby resolving the issue of potential localized overheating during the use of existing PVC heat stabilizer production cooling devices.

[0004] This utility model discloses a cooling device for the production of PVC heat stabilizers, achieved through the following specific technical means:

[0005] A cooling device for the production of PVC heat stabilizers includes a base plate, a shell, and connecting pipes;

[0006] A fixing frame is fixedly connected to the upper end of the base plate, and a base is fixedly connected to the upper left side of the base plate. A servo motor is installed on the base, and the motor shaft of the servo motor passes through the right side of the servo motor. The outer shell is placed inside the upper end of the fixing frame, and the inner surface of the fixing frame is fixedly connected to the outer surface of the outer shell. A baffle A is fixedly connected to the left side of the outer shell, and a baffle B is fixedly connected to the right side of the outer shell. A circular hole is provided on the upper side of the baffle A, and a feed pipe is fixedly connected to the circular hole on the baffle A. A circular hole is provided on the lower side of the baffle B, and a discharge pipe is fixedly connected to the circular hole on the lower side of the baffle B. The two sets of connecting pipes are respectively placed inside the left and right ends of the outer shell, and the outer sides of the two sets of connecting pipes are fixedly connected to the inner sides of the baffle A and the baffle B, respectively.

[0007] Furthermore, a heat-conducting pipe is fixedly connected between the two sets of connecting pipes.

[0008] Furthermore, the inner side of the outer shell is provided with a cooling pipe, which is wound around two sets of connecting pipes and heat-conducting pipes. The front end of the cooling pipe extends out of the left front side of the outer shell, and the rear end of the cooling pipe extends out of the right rear side of the outer shell.

[0009] Furthermore, the front end of the cooling pipe is connected to a water inlet pipe, the rear end of the cooling pipe is connected to a water outlet pipe, and a centrifugal pump is installed on the water outlet pipe.

[0010] Furthermore, the heat pipe has a spiral rod on its inner side, with the right end of the spiral rod penetrating the inner side of the baffle B and the left end of the spiral rod passing through the baffle A and connected to the motor shaft of the servo motor.

[0011] The cooling device for PVC heat stabilizer production as described in claim 1, characterized in that: a set of thermometers is installed on baffle A and baffle B respectively, and a set of bearings is respectively clamped on the inner side of baffle A and baffle B, with the inner surface of the inner ring of the bearing fixedly connected to the outer surface of the screw rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting up thermometers, this utility model facilitates real-time monitoring of whether the heat exchange efficiency has decreased, as a set of thermometers is installed on both baffle A and baffle B.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] Example: As attached Figure 1 To be continued Figure 5 As shown:

[0025] This utility model provides a cooling device for the production of PVC heat stabilizer, including a base plate 1, a shell 4, and a connecting pipe 11;

[0026] A mounting bracket 2 is fixedly connected to the upper end of the base plate 1, and a base is fixedly connected to the upper left side of the base plate 1. A servo motor 3 is mounted on the base, and the motor shaft of the servo motor 3 passes through the right side of the servo motor 3. The outer shell 4 is placed inside the upper end of the mounting bracket 2, and the inner surface of the mounting bracket 2 is fixedly connected to the outer surface of the outer shell 4. A baffle A5 is fixedly connected to the left side of the outer shell 4, and a baffle B6 is fixedly connected to the right side of the outer shell 4. A round hole is provided on the upper side of the baffle A5, and a feed pipe 8 is fixedly connected in the round hole on the baffle A5. A round hole is provided on the lower side of the baffle B6, and a discharge pipe 13 is fixedly connected in the round hole on the lower side of the baffle B6. Two sets of connecting pipes 11 are respectively placed inside the left and right ends of the outer shell 4, and the outer sides of the two sets of connecting pipes 11 are fixedly connected to the inner sides of the baffle A5 and the baffle B6, respectively.

[0027] Among them, such as Figure 3 As shown, a heat-conducting pipe 12 is fixedly connected between the two sets of connecting pipes 11. The heat-conducting pipe 12 serves as the direct carrier of the material. The outer wall of the heat-conducting pipe 12 is wrapped with the cooling pipe 9 throughout, which helps to extend the cooling path and make the heat exchange time between the material and the cooling pipe longer during the transmission process. In addition, the heat-conducting pipe 12 is made of a high thermal conductivity metal material with uniform pipe wall thickness, which can ensure that the heat transfer rate from the material to the coolant is consistent and avoid local overheating or cooling dead zones.

[0028] Among them, such as Figure 2 and Figure 4As shown, a cooling pipe 9 is provided on the inner side of the outer shell 4, and the cooling pipe 9 is wound around two sets of connecting pipes 11 and heat conduction pipes 12. The front end of the cooling pipe 9 extends out of the left front side of the outer shell 4, and the rear end of the cooling pipe 9 extends out of the right rear side of the outer shell 4. The front end of the cooling pipe 9 is connected to a water inlet pipe 10, and the rear end of the cooling pipe 9 is connected to a water outlet pipe 14. A centrifugal pump 15 is installed on the water outlet pipe 14. The winding structure of the cooling pipe 9 can cover the entire circumference of the heat conduction pipe, avoiding the problem of uneven heating and cooling in traditional single-sided cooling, ensuring that the material temperature drops evenly. The centrifugal pump 15 is used to precisely control the flow rate of the coolant to adapt to the cooling needs under different production capacities. For example, when the material temperature is high, the flow rate can be increased to accelerate heat dissipation.

[0029] Among them, such as Figure 3 As shown, a spiral rod 7 is provided on the inner side of the heat pipe 12, and the right end of the spiral rod 7 passes through the inner side of the baffle B6, while the left end of the spiral rod 7 passes through the baffle A5 and is connected to the motor shaft of the servo motor 3. The servo motor 3 drives the spiral rod 7 to rotate, generating axial thrust to transport the material from left to right. It can be linked with upstream reactors, downstream granulators, and other equipment to form an automated production line. The forced conveying of the spiral rod 7 ensures that the material passes through the heat pipe 12 without dead angles, which is especially suitable for high-viscosity PVC heat stabilizer melt, avoiding local overheating and decomposition due to stagnation.

[0030] Among them, such as Figure 5 As shown, a set of thermometers 17 are installed on baffles A5 and B6 respectively, and a set of bearings 16 are respectively installed on the inner side of baffles A5 and B6. The inner surface of the inner ring of the bearing 16 is fixedly connected to the outer surface of the screw rod 7. By installing thermometers 17 on baffles A5 and B6 respectively, the heat exchange efficiency can be monitored in real time. The two sets of bearings 16 ensure that the gap between the screw rod 7 and the inner wall of the heat conduction pipe 12 is uniform when the screw rod 7 rotates, preventing the material from having different flow rates or local stagnation due to uneven gaps.

[0031] The specific usage and function of this embodiment are as follows:

[0032] In this invention, by repeatedly squeezing the rubber ball 142, gas enters the pressure bag 10 through the rubber tube 141, causing the pressure bag 10 to expand. The pressure value is displayed on the electronic display screen 12 through the signal transmission of the pressure sensor 11 at the bottom. The pressure inside the pressure bag 10 is adjusted to a suitable value through the valve 143. The pressure bag 10 applies pressure to the plate 3, and the plate 3 squeezes the cotton wool in the groove 7 on the upper part of the fixed plate 6 connected to it. The medicine in the cotton wool is evenly applied to the patient's lesion through the injection hole 8, so that the fixed plate 6 performs pressure drug penetration therapy on the patient's lesion.

[0033] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.
