Description

Technical Field

[0001] This utility model belongs to the field of polyurethane sealant technology, specifically a cooling device for polyurethane sealant production. Background Technology

[0002] In the production of polyurethane sealants, the cooling process is one of the key steps to ensure product quality and performance. Polyurethane sealants are typically at a high temperature after the reaction. If cooling is not timely or uneven, it will not only affect the curing rate and final mechanical properties of the sealant, but may also cause quality defects such as bubbles and cracks due to localized overheating, thereby reducing the production pass rate and increasing production costs for the company.

[0003] Traditional cooling methods for polyurethane sealants often employ static cooling or simple water circulation cooling structures. Static cooling relies on natural heat dissipation or heat conduction through a single container wall, resulting in extremely low cooling efficiency. Furthermore, a significant temperature gradient easily forms within the sealant, with faster cooling near the container wall and slower cooling in the center, failing to meet the requirements of large-scale industrial production for cooling efficiency and uniformity. To address these issues, various improved cooling devices have emerged in the industry, with the patented device, CN220446962U, entitled "A Cooling Device for Polyurethane Sealant Production," being a typical example. This patented device attempts to cool the sealant by using a cooling jacket and water circulation pipeline, utilizing the flow of cooling water within the jacket. However, in practical applications, this device still exhibits significant technical limitations: its water circulation system relies solely on a single pipeline for cooling water input and output, lacking an active circulation drive and temperature control mechanism. The slow flow rate of cooling water within the jacket easily leads to localized overheating, resulting in low cooling efficiency. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a cooling device for polyurethane sealant production, which has the advantage of high cooling efficiency and solves the problem of low cooling efficiency of cooling devices.

[0005] This utility model provides the following technical solution: a cooling device for polyurethane sealant production, comprising: a cooling device, a circulating refrigeration structure, and a stirring cooling structure; The circulating cooling structure is fixedly connected to the top of the cooling device. It circulates the water inside the cooling device to prevent overheating. The stirring cooling structure is located on the top of the cooling device and stirs the polyurethane sealant to prevent dead zones inside the sealant and ensure uniform cooling.

[0006] The beneficial effects of this utility model are as follows: 1. This utility model, by setting up a cooling device, a circulating refrigeration structure and a stirring cooling structure, the circulating refrigeration structure is fixed on the top of the cooling device and can drive the internal water circulation, effectively avoiding overheating of the cooling water and ensuring continuous cooling capacity; the stirring cooling structure is fixed on the top of the cooling device and can stir the polyurethane sealant, eliminating cooling dead zones and achieving uniform cooling of the sealant. Overall, it solves the problems of low cooling efficiency and poor uniformity of traditional devices, and improves product quality.

[0007] 2. This utility model provides stable support for the overall structure through the base in the cooling device, while the motor drives the first and second helical gears to drive the upright and storage tank to move. This allows the polyurethane sealant in the storage tank to move with the storage tank during the cooling process, further assisting in the mixing of materials. In conjunction with the subsequent cooling structure, this improves the uniformity of cooling and meets the requirements of industrial production for cooling effect.

[0008] 3. This utility model uses a cooling water tank in a circulating cooling structure to store and maintain the temperature of cooling water, a cooling control panel to easily adjust cooling parameters, and a water pump to provide active driving force for cooling water circulation. The cooling water is transported to the cooling tank through pipes and then flows back to the cooling water tank through the circulation pipe, forming an efficient circulation loop.

Detailed Implementation

The stirring cooling structure 3 is set on the top of the cooling device 1. The stirring cooling structure 3 stirs the polyurethane sealant to prevent dead corners inside the polyurethane sealant and to make the polyurethane sealant cool evenly.

[0013] refer to Figure 7 The cooling device 1 includes a base 101, a cooling tank 102 is provided on the top of the base 101, a vertical plate 103 is fixedly connected to the left side of the top of the base 101, a motor 104 is fixedly connected inside the vertical plate 103, a helical gear 105 is fixedly connected to the output end of the motor 104, a helical gear 106 is provided on the top of the helical gear 105, the helical gear 106 meshes with the helical gear 105, a vertical rod 107 is fixedly connected inside the helical gear 106, and the top of the vertical rod 107 passes through the cooling tank 102 and extends to the interior of the cooling tank 102 where a storage tank 108 is fixedly connected.

[0014] In this embodiment, the base 101 in the cooling device 1 provides stable support for the overall structure, while the motor 104 drives the helical gear 105 and the helical gear 106 to drive the upright 107 and the storage tank 108 to rotate. This allows the polyurethane sealant in the storage tank 108 to move along with the storage tank 108 during the cooling process, further assisting in material mixing. This, combined with the subsequent cooling structure, improves the uniformity of cooling and meets the requirements of industrial production for cooling effect.

[0015] refer to Figure 5The circulating refrigeration structure 2 includes a refrigeration water tank 21. A refrigeration control panel 22 is fixedly installed on the rear side of the top of the refrigeration water tank 21. A water pump 23 is fixedly connected to the top of the refrigeration water tank 21. A pipe 24 is connected to the outlet of the water pump 23. The end of the pipe 24 away from the water pump 23 is connected to the cooling tank 102. Circulation pipes 25 are connected to the bottom of both sides of the cooling tank 102. The end of the circulation pipe 25 away from the cooling tank 102 is connected to the top of the refrigeration water tank 21.

[0016] In this embodiment, the cooling water tank 21 in the circulating cooling structure 2 can store and maintain the temperature of the cooling water, the cooling control panel 22 can easily adjust the cooling parameters, the water pump 23 provides active driving force for the cooling water circulation, the cooling water is transported to the cooling tank 102 through the pipe 24, and then flows back to the cooling water tank 21 through the circulation pipe 25, forming an efficient circulation loop, avoiding local stagnation and overheating of the cooling water, and significantly improving the cooling efficiency.

[0017] refer to Figure 6 The stirring and cooling structure 3 includes a horizontal plate 31. A motor 32 is fixedly connected to the top of the horizontal plate 31. The output end of the motor 32 passes through the horizontal plate 31 and extends to the bottom of the horizontal plate 31, where a transmission rod 33 is fixedly connected. A stirring blade 34 is fixedly connected to the surface of the transmission rod 33. Electric telescopic rods 35 are provided at the four corners of the bottom of the horizontal plate 31. The electric telescopic rods 35 are fixedly connected to the top of the cooling water tank 21, and the output end of the electric telescopic rods 35 is fixedly connected to the bottom of the horizontal plate 31.

[0018] In this embodiment, the motor 32 in the stirring and cooling structure 3 drives the transmission rod 33 and the stirring blade 34 to rotate, which can directly stir the polyurethane sealant in the storage tank 108 and eliminate dead corners inside the material.

[0019] refer to Figure 7 The four corners of the base 101 are fixedly connected to support legs 4, and the bottom of the support legs 4 is fixedly connected to a protective plate.

[0020] In this embodiment, by setting the support leg 4, a stable support can be provided for the entire device, preventing the device from shaking during operation. At the same time, the protective plate at the bottom of the support leg 4 increases the contact area with the ground, reduces the pressure on the ground, protects the ground from damage, and improves the stability and safety of the device during use.

[0021] refer to Figure 3 A sealed bearing 5 is fixedly connected to the top of the surface of the upright 107. The bottom of the outer ring of the sealed bearing 5 is fixedly connected to the bottom of the inner wall of the cooling tank 102. A stabilizing bearing 6 is fixedly connected to the bottom of the surface of the upright 107. The bottom of the outer ring of the stabilizing bearing 6 is fixedly connected to the top of the base 101.

[0022] In this embodiment, by setting a sealed bearing 5, the sealing performance of the connection between the upright 107 and the cooling tank 102 can be enhanced, preventing the cooling water in the cooling tank 102 from leaking. By setting a stabilizing bearing 6, the stability of the upright 107 during rotation can be improved, preventing the upright 107 from shifting or shaking due to long-term operation, ensuring the smooth operation of the storage tank 108, and extending the service life of the device.

[0023] refer to Figure 3 Support rods 7 are fixedly connected to the four corners of the bottom of the cooling tank 102, and the bottom of the support rods 7 is fixedly connected to the top of the base 101.

[0024] In this embodiment, the support rod 7 is provided to provide auxiliary support for the cooling tank 102, enhance the load-bearing capacity of the cooling tank 102, prevent the cooling tank 102 from deforming due to the internal storage of cooling water and the support of the storage tank 108, ensure the structural stability of the cooling tank 102, and ensure that the cooling process is carried out reliably.

[0025] refer to Figure 3 A fixing ring 8 is fixedly connected to the top of the surface of the upright 107, and the top of the fixing ring 8 is fixedly connected to the bottom of the storage tank 108.

[0026] In this embodiment, by setting the fixing ring 8, the connection strength between the upright 107 and the storage tank 108 can be strengthened, preventing the storage tank 108 from loosening or falling off during the operation of the upright 107, ensuring that the polyurethane sealant in the storage tank 108 can safely and stably carry out the cooling operation, and improving the safety and reliability of the device operation.

[0027] The polyurethane sealant to be cooled is injected into the storage tank 108 of the cooling device 1. Then, the main control system of the device is activated, supplying power to the circulating refrigeration structure 2, the stirring cooling structure 3, and the drive components of the cooling device 1, ensuring that each structure is in a ready-to-operate state. The motor 104 inside the vertical plate 103 of the cooling device 1 drives the helical gear 105 to rotate. Since the helical gear 105 meshes with the helical gear 106, the helical gear 106 drives the internally fixed vertical rod 107 to rotate. The vertical rod 107 drives the storage tank 108 to rotate synchronously, allowing the polyurethane sealant inside the storage tank 108 to rotate. Initially, circular motion is generated, breaking the static state and laying the foundation for subsequent uniform cooling. Then, the cooling water tank 21 and water pump 23 of the circulating cooling structure 2 are activated. The target temperature of the cooling water is set via the cooling control panel 22 and adjusted according to the cooling requirements of the sealant. The internal cooling components of the cooling water tank 21 begin to work, cooling the water inside to the set temperature. Subsequently, the water pump 23 generates driving force, transporting the low-temperature cooling water in the cooling water tank 21 through the pipe 24 to the cooling tank 102 of the cooling device 1. The cooling water in the cooling tank 102 surrounds the outer wall of the storage tank 108, absorbing heat from the storage tank 108 and its interior through heat conduction. The heat absorbed by the sealant causes the cooling water temperature to rise. This heat is then returned to the cooling water tank 21 via the circulation pipes 25 at the bottom of both sides of the cooling tank 102. After being cooled again by the refrigeration components, it enters the next cycle, forming a closed loop of "refrigeration-transportation-heat absorption-return-re-refrigeration". This prevents localized overheating of the cooling water and ensures continuous and stable cooling capacity. Finally, the electric telescopic rod 35 and motor 32 of the stirring and cooling structure 3 are activated. The electric telescopic rod 35 adjusts the height of the horizontal plate 31 according to the sealant level in the storage tank 108, causing the stirring blades 34 on the transmission rod 33 at the bottom of the horizontal plate 31 to extend into the sealant. The motor 32... After startup, the output end drives the transmission rod 33 and the stirring blade 34 to rotate at high speed, which radially stirs the sealant in the storage tank 108, eliminating the cooling dead zones inside the sealant, such as the temperature difference between the central and edge areas. At the same time, the storage tank 108 continues to rotate with the upright rod 107. The sealant is fully mixed under the dual action of "circular rotation + radial stirring", ensuring that each part of the sealant can fully contact the inner wall of the storage tank 108, efficiently absorbing the cooling water in the cooling tank 102, and finally achieving rapid and uniform cooling of the polyurethane sealant. The rotation direction of the storage tank 108 is opposite to the rotation direction of the stirring blade 34.
