Description

Technical Field

[0001] This application relates to the technical field of air compressors, and more particularly, to a cooling structure for a special air compressor for ammonia synthesis. Background Art

[0002] An air compressor is an important device in ammonia synthesis production. When ammonia synthesis is carried out under high temperature and high pressure, the temperature of the air compressor is relatively high. To solve the problem of the air compressor running at full load in high-temperature seasons, a cooling structure is generally configured on the air compressor. The patent with the publication number CN214887582U discloses an air compressor cooling device with a circulation structure, which transports the hot air inside the air compressor to the outside of the machine room through a radiator fan, reducing the ambient temperature in the machine room. However, the above disclosure still has the defect of the disassembly and assembly of the flow equalizing plate, in which the gas is evenly introduced into the air collecting cover through the flow equalizing plate and cooled by the radiator fan. For this reason, the inventor has proposed a cooling structure for a special air compressor for ammonia synthesis. Utility Model Content

Rotatable handles are provided inside the two mounting plates. Threads with opposite rotation directions are provided at both ends of the handle.

[0037] Embodiment 1

[0038] Please refer to Figures 1-3 , this embodiment provides a cooling structure for a special air compressor for synthetic ammonia to improve the convenience of disassembly and assembly of the flow equalizing plate.

[0039] In this embodiment, the cooling structure of the special air compressor for synthetic ammonia includes an installation box 20 with a heat dissipation fan 21 provided between the air outlet of the air compressor body 10 and the exhaust pipe 11. The inner wall of the installation box 20 is provided with a slot 22 for inserting the flow equalizing plate 30. Opposite mounting plates 31 are provided on the side walls of the flow equalizing plate 30. Rotatable handles 32 are provided inside the two mounting plates 31. The two ends of the handle 32 have threads with opposite helix directions. The outer sides of the mounting plates 32 are slidably inserted with positioning rods 33. The inner ends of the positioning rods 33 are screwed into the inside of the handle 32. The top ends of the positioning rods 33 have limit rods 332 that pass through the side wall of the installation box 20 and are inserted into the side wall of the flow equalizing plate 30.

[0040] In this embodiment, by rotating the handle 32, the two positioning rods 33 are driven to move synchronously towards or away from each other, thereby controlling the limiting state of the limit rod 332 on the flow equalizing plate 30, making the disassembly and assembly of the flow equalizing plate 30 in the installation box 20 more convenient.

[0041] It should be noted that the installation box 20 is integrally constructed as a rectangular box. The installation box 20 is welded between the air outlet of the air compressor body 10 and the exhaust pipe 11 to realize the conduction between the air compressor body 10 and the exhaust pipe 11. The heat dissipation fan 21 is fixedly connected to the bottom of the installation box 20 to convey the gas inside the air compressor body 10 to the inside of the exhaust pipe 11. The slot 22 is formed inside the installation box 20, and the slot 22 is constructed as a rectangular ring adapted to the outer shape of the installation box 20. The plane where the slot 22 is located is perpendicular to the gas flow direction. One side edge of the slot 22 penetrates through the outer wall of the installation box 20 to form an installation opening 23. The flow equalizing plate 30 is inserted into the slot 22 through the installation opening 23. In order to improve the sealing performance, sealing rings 35 are provided on both the upper and lower surfaces of the flow equalizing plate 30, and the sealing rings 35 are pressed between the flow equalizing plate 30 and the slot 22.

[0042] In addition, the overall current-sharing plate 30 is configured as a rectangular plate adapted to the outer shape of the slot 22, and a plurality of current-sharing holes are arranged in an array on the current-sharing plate 30. The two mounting plates 31 are fixedly connected to the side walls of the current-sharing plate 30 and extend to the outside of the mounting box 20 at the mounting openings 23. The mounting plates 31 are perpendicularly arranged with respect to the side walls of the current-sharing plate 30, and circular positioning holes 311 for clamping the handle 32 are provided on the inner side walls of the mounting plates 31. The axis of the positioning hole 311 is parallel to the extending direction of the mounting opening 23. Both ends of the handle 32 are rotatably clamped inside the positioning hole 311, and the handle 32 as a whole is perpendicularly arranged with respect to the mounting plate 31; a rectangular limiting hole 312 for passing through the positioning rod 33 is provided on the outer side wall of the mounting plate 31. The limiting hole 312 communicates with the positioning hole 311. The positioning rod 33 is configured as a rectangle in cross-section, and the positioning rod 33 is slidably passed through the limiting hole 312. The limiting hole 312 restricts the rotation of the positioning rod 33. The inner end of the positioning rod 33 extends into the handle 32 and is threadedly connected with the handle 32. The outer end of the positioning rod 33 is bent to form a limiting rod 332 parallel to the positioning rod 33.

[0043] In addition, the two ends of the handle 32 have threads with opposite helix directions. A cylindrical connecting column 331 is fixedly connected to the inner end of the positioning rod 33. The connecting column 331 is in screw-threaded connection with the threads at the end of the handle 32, so that the rotation of the handle 32 can drive the two positioning rods 33 on both sides to move synchronously towards or away from each other. Plugging holes 34 corresponding to the limiting rods 332 are provided on the side walls of the mounting box 20 and the current-sharing plate 30. When the two positioning rods 33 are driven to move towards each other by rotating the handle 32, the limiting rods 332 can sequentially penetrate into the plugging holes 34 on the mounting box 20 and the current-sharing plate 30, thereby realizing the locking of the current-sharing plate 30 inside the mounting box 20; similarly, when the handle 32 is rotated in the reverse direction, the limiting rods 332 will move out of the plugging holes 34. At this time, by pulling the handle 32 outwards, the current-sharing plate 30 can be removed from the slot 22 on the mounting box 20, improving the convenience of disassembling and assembling the current-sharing plate 30 on the mounting box 20.

[0044] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application.
