Description

Technical Field

[0001] The present application relates to the field of heat exchange coils, and more particularly to a nitrogen filling head for heat exchange coils. Background Art

[0002] A heat exchanger (also known as a heat exchanger or heat exchange equipment) is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction. Heat exchangers can be classified in different ways. Based on their operating process, they can be divided into three categories: partitioning type, hybrid type, and thermal storage type (or heat recovery type); based on the compactness of their surface, they can be divided into compact and non-compact types.

[0003] The heat exchange coil is a major component of the heat exchanger. Nitrogen needs to be flushed into the coil before use. However, existing nitrogen inflation heads are prone to leakage during actual inflation. The coil consists of multiple pipes, resulting in different air pressures within the coil, affecting its heat exchange efficiency. Utility Model Content

[0004] In order to solve the problem of air leakage during inflation of existing heat exchange coils, the present application provides a nitrogen inflation head for the heat exchange coils.

[0005] The present application provides a nitrogen inflator for a heat exchange coil using the following technical solution:

[0006] A nitrogen inflation head for a heat exchange coil comprises an outer shell, an inflation mechanism installed in the outer shell, and a placement mechanism. The inflation mechanism comprises an adjustment box fixedly connected to the inner wall of the outer shell, and the outer wall of the adjustment box is slidably connected to a mounting frame.

The bottom outer wall of the inflation head is provided with a plurality of inflation ports distributed at equal distances, and the outer wall of the inflation head is fixedly connected to a plurality of connecting pipes connected to the inflation ports.

[0007] By adopting the above technical solution, the installation of the inflation mechanism and the placement mechanism is facilitated by the setting of the outer shell, and the mounting frame is slidably installed on the adjustment box. When the mounting frame moves, it is convenient to drive the inflation head to rise and fall, thereby facilitating the compression and fixation of the heat exchange coil. The inflation port on the inflation head is connected to the heat exchange coil for easy inflation.

[0008] The detection assembly includes a detection box fixedly connected to the mounting frame, and an opening is provided on the outer wall of the bottom of the detection box. The inner wall of the opening is slidably connected to a driving seat fixedly connected to the inflation head.

[0009] By adopting the above technical solution, the detection assembly can be conveniently installed on the mounting frame through the provision of the detection box, and the drive seat slides in the detection box.

[0010] The inner walls on both sides of the detection box are fixedly connected to the same fixed rod, and the outer wall of the fixed rod is slidably connected to two symmetrically arranged sliding sleeves. The outer walls of the two sliding sleeves are rotatably connected to support plates, and one end of the two support plates is rotatably connected to the drive seat.

[0011] By adopting the above technical solution, when the driving seat slides, the sliding sleeve will be driven to slide on the fixed rod through the support plate.

[0012] The outer wall of the fixing rod is sleeved with four symmetrically arranged springs, the midpoint of the fixing rod is fixedly connected with a contact seat, and the top outer wall of the driving seat is fixedly connected with a distance measuring sensor.

[0013] By adopting the above technical solution, the spring on the fixed rod is conveniently compressed when the fixed rod slides, and the distance measuring sensor is conveniently driven close to or away from the contact seat when the driving seat slides. The setting of the distance measuring sensor facilitates the detection of the displacement distance of the driving seat.

[0014] The inner walls on both sides of the regulating box are rotatably connected to the same screw rod, and the outer wall of the screw rod is screwed with a connecting seat, which is fixedly connected to the mounting frame. The outer wall of the top of the regulating box is fixedly connected to a servo motor, and the output shaft of the servo motor is fixedly connected to the screw rod.

[0015] By adopting the above technical solution, the servo motor directly drives the screw rod to rotate, and when the screw rod rotates, it is convenient to directly drive the mounting frame to slide through the connecting seat.

[0016] The placement mechanism includes a support frame fixedly connected to the inner wall of the bottom of the shell, the top outer wall of the support frame is slidably connected to a sliding seat, the top outer wall of the sliding seat and one side of the top outer wall of the support frame are both installed with clamping assemblies, the top outer wall of the support frame is fixedly connected to cylinder 1, and the piston rod of cylinder 1 is fixedly connected to the sliding seat.

[0017] By adopting the above technical solution, the setting of the cylinder 1 facilitates the movement of the sliding seat, and the distance between the two clamping components is conveniently adjusted when the sliding seat moves.

[0018] The clamping assembly includes a second cylinder, and a connecting plate is fixedly connected to the piston rod of the second cylinder.

[0019] By adopting the above technical solution, the connection plate can be easily driven to move by the setting of the second cylinder.

[0020] The outer wall of the top of the support frame is slidably connected to a placement platform, the connecting plate is pressed tightly against the outer wall of the placement platform, and the placement platform is located directly below the inflation head.

[0021] By adopting the above technical solution, the second cylinder is provided to facilitate the movement of the connecting plate, so that the connecting plate can be directly pressed and fixed.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application facilitates the direct downward movement of the inflation head by arranging a servo motor and a screw in the inflation mechanism. This facilitates the compression and fixation of the heat exchange coil when the inflation head moves downward, thereby facilitating the injection of nitrogen. Furthermore, a detection component is provided between the mounting frame and the inflation head. The detection component facilitates the horizontal compression of the inflation head against the heat exchange coil, thereby preventing air leakage during operation of the inflation head.

[0024] 2. This application sets a driving seat in the detection component. When the driving seat moves, it is convenient to drive the distance measuring sensor close to or away from the contact seat. The setting of the distance measuring sensor is convenient for detecting the distance moved by the inflation head. The two distance measuring sensors detect the displacement distance of the inflation head. When convenient, the inflation head is in a horizontal position to avoid it from tilting and causing leakage. BRIEF DESCRIPTION OF THE DRAWINGS

The top outer wall of the adjusting box 4 is fixedly connected to the servo motor 5, and the output shaft of the servo motor 5 is fixedly connected to the screw rod.

[0035] During use, the servo motor 5 directly drives the screw rod to rotate.

The setting of the outer shell 1 is convenient for installing the inflation mechanism 2 and the placement mechanism 3. The mounting bracket 6 is slidably installed on the adjustment box 4. When the mounting bracket 6 moves, it is convenient to drive the inflation head 7 to rise and fall, thereby facilitating the compression and fixation of the heat exchange coil. The inflation port 25 on the inflation head 7 is connected to the heat exchange coil for convenient inflation.

[0036] Reference Figure 5 The detection assembly 15 includes a detection box 16 fixedly connected to the mounting frame 6, and an opening is provided on the outer wall of the bottom of the detection box 16. The inner wall of the opening is slidably connected to a drive seat 22 fixedly connected to the inflation head 7. The inner walls of both sides of the detection box 16 are fixedly connected to the same fixed rod 17, and the outer wall of the fixed rod 17 is slidably connected to two symmetrically arranged sliding sleeves 20. The outer walls of the two sliding sleeves 20 are rotatably connected to support plates 21, and one end of the two support plates 21 is rotatably connected to the drive seat 22. The outer wall of the fixed rod 17 is sleeved with four symmetrically arranged springs 18. A contact seat 19 is fixedly connected at the midpoint of the fixed rod 17, and a distance measuring sensor 23 is fixedly connected to the top outer wall of the drive seat 22.

[0037] During use, the detection assembly 15 is conveniently installed on the mounting frame 6 through the setting of the detection box 16, and the driving seat 22 slides in the detection box 16. When the driving seat 22 slides, it will drive the sliding sleeve 20 to slide on the fixed rod 17 through the support plate 21. When the fixed rod 17 slides, it is convenient to compress the spring 18 on the fixed rod 17. When the driving seat 22 slides, it is convenient to drive the distance measuring sensor 23 close to or away from the contact seat 19. The setting of the distance measuring sensor 23 facilitates the detection of the displacement distance of the driving seat 22.

[0038] Reference Figure 1-2 The placement mechanism 3 of the auxiliary heat exchange coil includes a support frame 24 fixedly connected to the bottom inner wall of the outer shell 1, and the top outer wall of the support frame 24 is slidably connected to the sliding seat 10.

The setting of cylinder 2 12 facilitates the movement of the connecting plate 13, and facilitates the direct pressing and fixing of the connecting plate 13.

[0040] The implementation principle of a nitrogen inflating head for a heat exchange coil in the embodiment of the present application is as follows: when in use, the heat exchange coil to be inflated is first placed on the placement table 14, and then the servo motor 5 is started. When the servo motor 5 is started, it directly drives the screw rod to rotate, and when the screw rod rotates, it directly drives the mounting frame 6 to drive the inflating head 7 to descend. When the inflating head 7 descends, it is pressed tightly on the heat exchange coil, and the pipe mouth of the coil is inserted into the inflating port 25 on the inflating head 7. When pressed tightly, the inflating head 7 pushes the drive seat 22 to slide in the detection box 16, driving When the movable seat 22 slides, the support plate 21 pushes the sleeve 20 to slide on the fixed rod 17. When the sleeve 20 slides, it is convenient to compress the spring 18. At the same time, the distance sensor 23 will approach or move away from the contact seat 19. The displacement of the inflation head 7 can be detected by the two distance sensors 23, thereby ensuring the horizontal state of the inflation head 7 and avoiding it from tilting and causing air leakage when the coil is inflated. The cylinder 2 12 in the two clamping assemblies 11 conveniently drives the connecting frame 13 to fix the placement table 14.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
