Description

Technical Field

[0001] This utility model belongs to the field of cooling technology for rail insulating joints, and in particular relates to a cooling device. Background Technology

[0002] The insulating joint includes a fishtail plate and a protective plate surrounding the fishtail plate. An insulating layer is placed between the fishtail plate and the protective plate. Heating and melting the insulating layer allows the fishtail plate and the protective plate to bond together, forming the insulating joint. The insulating joint is formed within a mold. After forming, both the mold and the insulating joint need to be cooled. Water cooling is generally used due to its relatively high efficiency. However, the insulating layer within the insulating joint undergoes a process of heating, melting, and then cooling and solidifying to achieve bonding. Cooling water entering the insulating layer can interfere with this bonding process. Therefore, water cooling is not suitable for the insulating joint. To address this issue, a combination of air cooling and water cooling is used to cool the insulating joint and the mold. Air cooling primarily cools the insulating joint within the mold, while water cooling cools the lower surface of the mold.

[0003] Therefore, it is necessary to provide a cooling device to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0027] Please refer to Figures 1-6This embodiment is a cooling device 6, which includes an air-cooling mechanism 61 and a water-cooling mechanism 62. The air-cooling mechanism 61 is located above the water-cooling mechanism 62. An active space for placing the object to be cooled is provided between the air-cooling mechanism 61 and the water-cooling mechanism 62. Specifically, the insulating connector 10 and the mold 20 used to position the insulating connector 10 are located between the air-cooling mechanism 61 and the water-cooling mechanism 62. The air-cooling mechanism 61 blows air downwards to cool the upper surface of the insulating connector 10 and the mold 20, while the water-cooling mechanism 62 sprays water upwards to cool the bottom of the mold 20. The cooling action is performed simultaneously from both the top and bottom. The mold 20 is used to prevent hot air from entering the water-cooling mechanism 62 and to prevent the cooling water from contacting the insulating connector 10, which can ensure that the water cooling and air cooling do not interfere with each other and can also improve the cooling efficiency. The air-cooling mechanism 61 includes an air inlet bracket 611, an air inlet pipe 613 set at the upper end of the air inlet bracket 611, and a plurality of air-cooling components 612 set at the bottom of the air inlet bracket 611. The air-cooling mechanism 61 is slidably mounted on a mounting beam 63. The air-cooled component 612 extends horizontally, and each air-cooled component 612 has several air outlets 614 along its length at its bottom. An air-cooling channel is interconnected between the air inlet bracket 611 and the interior of the air-cooled component 612, and this air-cooling channel is interconnected with the air inlet pipe 613 and the air outlets 614. The air blown out of the air outlets 614 cools the insulating joint. In other embodiments, it can be used to cool other products similar in nature to the insulating joint 10; the specific product is not limited.

[0028] In this embodiment, two air-cooled components 612 are arranged opposite each other on the left and right sides. In order to ensure that the air blown out by the two air-cooled components 612 can blow onto the entire insulating joint, the air outlets 614 of the two air-cooled components 612 are both inclined towards the center. Figure 3 As shown, this arrangement ensures that all air-cooled components 612 can blow air from one end to the center, with an inclination angle of 5~10°. In other embodiments, if a further improvement in air-cooling effect is required, the number of air-cooled components 612 can be increased. When multiple air-cooled components 612 are arranged, the direction of the air outlet 614 can also be directly vertical. Therefore, the number of air-cooled components 612 and the inclination angle of the air outlet 614 can be set according to the actual situation and are not limited here.

[0029] The water cooling mechanism 62 includes a water tank 621 for containing cooling water, a high-pressure water spray pipe 622 disposed inside the water tank 621 and spraying water upward, and a first circulating water pump assembly 623 connected to the high-pressure water spray pipe 622.

[0030] The high-pressure water spray pipe 622 includes a first connecting pipe 6221 and a water spray pipe 6222 provided at the end of the first connecting pipe 6221. A number of water outlet holes 6223 are provided on the water spray pipe 6222, and the water outlet holes 6223 spray water upward to cool the bottom of the mold 20. In this embodiment, the water spray pipe 6222 has a "day" - shaped structure to facilitate more sufficient water spraying and cooling of the mold 20. In other embodiments, the structure of the water spray pipe 6222 can be set according to the actual situation and is not limited here.

[0031] The first circulating water pump assembly 623 is located outside the water tank 621. The first circulating water pump assembly 623 includes a first water inlet pipe 6231 connected to the first connecting pipe 6221 and a first circulating water pump 6232 connected to the first water inlet pipe 6231. In order to realize the recycling of cooling water, the water tank 621 is connected with a first water outlet pipe 6233 below the first water inlet pipe 6231, and the other end of the first water outlet pipe 6233 is connected to the first circulating water pump 6232. That is, under the action of the first circulating water pump 6232, the water in the water tank 621 flows into the first circulating water pump 6232 through the first water outlet pipe 6233, flows into the first water inlet pipe 6231 from the first circulating water pump 6232, and finally sprays upward through the water spray pipe 6222 to cool the mold 20. The first water outlet pipe 6233, the first circulating water pump 6232 and the first water inlet pipe 6231 can realize the recycling of cooling water and reduce production costs.

[0032] A water inlet 6211 is provided on one side of the water tank 621, and a water outlet 6212 is provided on the other side. First valves 6213 are provided at both the water inlet 6211 and the water outlet 6212. When clean cooling water needs to be injected into the water tank 621, the first valve 6213 at the water inlet 6211 is opened to inject cooling water. After the cooling water reaches the set water level, the first valve 6213 at the water inlet 6211 is closed. If it is necessary to discharge the cooling water in the water tank 621, the first valve 6213 at the water outlet 6212 is opened to discharge the cooling water. When the water cooling mechanism 62 performs the water spraying and cooling action, the first valves 6213 at the water inlet 6211 and the water outlet 6212 are both in the closed state.

[0033] A tank cover 6214 is provided above the water tank 621. The tank cover 6214 is provided with an avoidance through - hole directly below the mold 20 to facilitate the upward spraying of cooling water to cool the bottom of the mold 20. The provided tank cover 6214 can block hot air from entering the lower water cooling mechanism 62, can prevent hot air from entering the water cooling mechanism 62 and causing the internal temperature of the water tank 621 to rise, and can ensure the cooling effect of water cooling.

[0034] Inside the water tank 621, below the water spray pipe 6222, there is a filter screen 624 for filtering out the residue that falls from the insulating joint and the mold 20. When the filter screen 624 is covered with a certain amount of residue, the filter screen 624 is removed, cleaned, and the clean filter screen 624 is put back into the water tank 621 to continue the residue filtering operation.

[0035] The water tank 621 is equipped with a water level sensor 627 and a temperature sensor 626. The water level sensor 627 is used to detect the water level in the water tank 621, and the temperature sensor 626 is used to detect the water temperature in the water tank 621.

[0036] After multiple water sprays from the water spray pipe 6222, the cooling water absorbs heat, causing the temperature inside the water tank 621 to gradually rise. If the temperature inside the water tank 621 exceeds the set temperature, the cooling efficiency will decrease. To solve this problem, a cooling water replacement mechanism 625 is connected to the water tank 621. The cooling water replacement mechanism 625 draws the high-temperature cooling water from the water tank 621 to the cooling tower for cooling. Once the set temperature is reached, the low-temperature cooling water is then drawn back into the water tank 621. The cooling tower is existing technology, and any design using existing technology is acceptable; no limitations are imposed here.

[0037] The cooling water replacement mechanism 625 includes a second outlet pipe 6251 and a second inlet pipe 6252 connected to the water tank 621. The second outlet pipe 6251 is below the second inlet pipe 6252. The other ends of the second outlet pipe 6251 and the second inlet pipe 6252 are connected to the second circulating water pump 6253. A third outlet pipe 6254 is connected in the middle of the second inlet pipe 6252. A first solenoid valve 6255 is connected to the second inlet pipe 6252 near the water tank 621, and a second solenoid valve 6256 is connected to the second circulating water pump 6253. The third outlet pipe 6254 is located between the first solenoid valve 6255 and the second solenoid valve 6256.

[0038] The working principle of the cooling water replacement mechanism 625 is as follows: When the temperature sensor 626 detects that the water temperature in the water tank 621 is higher than the first temperature (e.g., 22℃), the second circulating water pump 6253 starts to work, and the second solenoid valve 6256 opens while the first solenoid valve 6255 closes. The cooling water in the water tank 621 flows into the second circulating water pump 6253 through the second outlet pipe 6251, then into the second inlet pipe 6252 through the second solenoid valve 6256, and finally into the cooling tower through the third outlet pipe 6254 for cooling. When the water temperature in the cooling tower drops to the second temperature (e.g., 18℃), the cooled water needs to flow back into the water tank 621. At this time, the second solenoid valve 6256 closes while the first solenoid valve 6255 opens. The cooling water in the cooling tower flows into the first solenoid valve 6255 through the third outlet pipe 6254, then into the water tank 621 through the second inlet pipe 6252, thus realizing the replacement of the cooling water in the water tank 621. The set values ​​for the first and second temperatures are determined based on actual conditions and are not restricted here.

[0039] The upper surface of mold 20 is provided with several positioning grooves, each of which carries an insulating joint 10. The positioning grooves do not penetrate to the lower surface of mold 20, nor are they connected to it. During water cooling, mold 20 acts as an insulator, with cooling water sprayed upwards to cool the bottom of mold 20. However, due to the insulator effect of mold 20, the cooling water cannot contact the insulating joint 10, thus avoiding interference with the bonding process of the insulating joint 10 and ensuring the quality of the insulating joint molding. Simultaneously, during air cooling, the airflow only blows towards the insulating joint 10, and air cooling involves convection exchange with the surrounding air. Due to the insulator effect of mold 20, hot air is prevented from entering the water cooling mechanism 62 below, preventing the internal temperature of water tank 621 from rising and ensuring the cooling effect of water cooling. Therefore, the combined air cooling and water cooling mechanisms can simultaneously cool the insulating joint 10 and mold 20 respectively, without interference between the two processes, thus improving cooling efficiency.

[0040] In this embodiment, the mold 20 is positioned on a rotary table 30. The rotary table 30 extends outward to form a positioning frame 301 for positioning the mold 20. The rotary table 30 drives the mold 20 to rotate from the previous processing station into the active space, where it is then subjected to air cooling and water cooling. After cooling, the rotary table 30 drives the mold 20 to rotate from the active space to the next processing station for subsequent processing. Therefore, clearance spaces are provided at both ends of the active space to allow the rotary table 30 to drive the mold 20 into or out of the active space.

[0041] In other embodiments, the mold 20 can also enter the active space from the front-rear direction. There are no restrictions on how the mold 20 enters the active space, and it can be adjusted according to the actual situation.

[0042] When using the cooling device 6 provided in this solution, cooling water is first injected into the water tank 621. When the insulating joint and the mold used to form the insulating joint are located between the air cooling mechanism 61 and the water cooling mechanism 62, the air cooling mechanism 61 and the water cooling mechanism 62 work simultaneously. The air cooling mechanism 61 blows air downwards to cool the insulating joint, and the water cooling mechanism 62 sprays water upwards to cool the mold. The specific air cooling process of the air cooling mechanism 61 is as follows: cold air is introduced into the air inlet pipe 613, and the cold air enters the air outlet 614 from the air cooling channel. The air cooling component 612 blows air from one end to the middle to cool the insulating joint. The specific water cooling process of the water cooling mechanism 62 is as follows: the first circulating water pump 6232 is activated, so that the water in the water tank 621 flows into the first circulating water pump 6232 through the first water outlet pipe 6233, flows into the first water inlet pipe 6231 from the first circulating water pump 6232, and finally sprays it upwards through the water spray pipe 6222 to cool the mold.

[0043] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
