Description

Technical Field

[0001] This utility model relates to the field of nitrogen generator technology, specifically a heat dissipation structure for a nitrogen generator. Background Technology

[0002] Nitrogen generators, as a key industrial device, are widely used in various applications requiring nitrogen supply. Their stability and durability are crucial for ensuring the continuity of production processes and product quality.

[0003] To ensure that nitrogen generators can operate efficiently for extended periods, cooling fans are typically used as the core component of their cooling system. By accelerating airflow, the cooling fan effectively removes the heat generated inside the nitrogen generator during operation, thereby maintaining its operating temperature within a reasonable range and preventing performance degradation or equipment damage caused by overheating.

[0004] However, in practical applications, the continuous rotation of the fan blades draws in air from the surrounding environment. This air often contains a certain amount of dust, particles, and other impurities. These impurities gradually accumulate at the fan's air inlet and on the surface of the blades. The accumulation of dust not only increases the operating load of the fan and reduces its speed and efficiency, but also seriously affects the fan's heat dissipation performance. This prevents the heat inside the nitrogen generator from being dissipated in time, which in turn affects the normal working condition of the nitrogen generator and may even shorten its service life. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation structure for a nitrogen generator, in order to solve the problem mentioned in the background art that dust accumulates on the cooling fan during use, affecting the fan's heat dissipation performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat dissipation structure for a nitrogen generator includes: a nitrogen generator body, a cooling fan mounted on the nitrogen generator body, a filter screen mounted on the outer side of the nitrogen generator body, a replacement component mounted on the nitrogen generator body, the replacement component including an outer frame mounted on the nitrogen generator body, a mounting bracket mounted on the outer frame, a rotating component mounted on the mounting bracket, and a limit post mounted on the outer frame; the replacement component is used for replacing the filter screen; and a fixing component mounted on the mounting bracket, the fixing component including a slot mounted on the rotating component, and a sliding plate mounted on the mounting bracket; the fixing component is used for fixing the rotating component.

[0008] Preferably, the replacement component also includes a lead screw at one end of the rotating part, one end of the lead screw being threaded onto the mounting bracket, and the lead screw passing through the mounting bracket.

[0009] Preferably, a horizontal plate is rotatably provided at one end of the lead screw, and a fixing groove is provided on the mounting bracket corresponding to the horizontal plate, with the horizontal plate movably disposed in the fixing groove.

[0010] Preferably, a connecting groove is provided on the inner side of the outer frame, and a fixing frame is provided on the outer side of the filter screen, with the fixing frame movably disposed within the connecting groove.

[0011] Preferably, a fixing block is provided in the middle of the fixing frame, and a sliding groove is provided in the middle of the connecting groove, with the fixing block movably disposed in the sliding groove.

[0012] Preferably, limit posts are provided on both sides of the horizontal plate, and limit holes are provided on the fixed frame corresponding to the limit posts, with the limit posts being movably positioned within the limit holes.

[0013] Preferably, the fixing component also includes a horizontal groove on the mounting bracket corresponding to the slide plate, and the slide plate is movably disposed in the horizontal groove.

[0014] Preferably, a handle is provided at the middle of the upper end of the skateboard, the skateboard is movably mounted in the slot, and a placement slot is provided on the mounting frame corresponding to the rotating component, the rotating component being movably mounted in the placement slot.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By rotating the rotating component, the limiting post can be moved up and down, allowing it to slide into or out of the limiting hole. This enables the filter screen to be disassembled and installed, allowing staff to quickly replace the filter screen when it is covered with dust. This provides good protection for the cooling fan and effectively prevents dust from adhering to it, thus maintaining the cooling fan's heat dissipation effect.

[0017] After the filter screen is replaced, the rotating part moves into the placement slot, and the slot and the slide plate are at the same level. By pulling the handle, the slide plate is locked into the slot, which can fix the rotating part and prevent external factors from causing the rotating part to rotate. Attached Figure Description

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] like Figure 1-7 As shown, this application provides a heat dissipation structure for a nitrogen generator, including a nitrogen generator body 1, a cooling fan 3 disposed on the nitrogen generator body 1, a filter screen 2 disposed on the outer side of the nitrogen generator body 1, and a replacement assembly disposed on the nitrogen generator body 1. The replacement assembly includes an outer frame 4 disposed on the nitrogen generator body 1, a mounting bracket 5 disposed on the outer frame 4, a rotating component 8 disposed on the mounting bracket 5, and a limit post 6 disposed on the outer frame 4. The replacement assembly is used for replacing the filter screen 2.

[0029] Specifically, such as Figure 3 As shown, the replacement component also includes a lead screw 12 at one end of the rotating part 8. One end of the lead screw 12 is threaded onto the mounting bracket 5, and the lead screw 12 passes through the mounting bracket 5. The rotation of the lead screw 12 can be better controlled by rotating the rotating part 8.

[0030] Specifically, such as Figure 4As shown, a horizontal plate 7 is rotatably mounted on one end of the lead screw 12. A fixing groove 20 is provided on the mounting bracket 5 corresponding to the horizontal plate 7. The horizontal plate 7 is movably mounted in the fixing groove 20. By rotating the lead screw 12, the horizontal plate 7 can be driven to move stably up and down inside the fixing groove 20.

[0031] Specifically, such as Figure 3 As shown, a connecting groove 10 is provided on the inner side of the outer frame 4, and a fixing frame 14 is provided on the outer side of the filter screen 2. The fixing frame 14 is movably disposed in the connecting groove 10. By inserting the fixing frame 14 into the connecting groove 10, the filter screen 2 can be pre-positioned.

[0032] Specifically, such as Figure 6 As shown, a fixing block 9 is provided in the middle of the fixing frame 14, and a sliding groove 11 is provided in the middle of the connecting groove 10. The fixing block 9 is movably disposed in the sliding groove 11. Through the cooperation of the fixing block 9 and the sliding groove 11, the fixing frame 14 can be easily inserted into the connecting groove 10.

[0033] Specifically, such as Figure 4 As shown, limit posts 6 are provided on both sides of the horizontal plate 7, and limit holes 13 are provided on the fixed frame 14 corresponding to the limit posts 6. The limit posts 6 are movably set in the limit holes 13. By sliding the limit posts 6 into the limit holes 13, the filter screen 2 can be quickly fixed.

[0034] The mounting bracket 5 is provided with a fixing component, which includes a slot 19 provided on the rotating part 8 and a sliding plate 17. The fixing component is used to fix the rotating part 8.

[0035] Specifically, such as Figure 7 As shown, the fixing component also includes a horizontal groove 16 provided on the mounting bracket 5 corresponding to the slide plate 17. The slide plate 17 is movably disposed in the horizontal groove 16. By sliding the slide plate 17 inside the horizontal groove 16, the movement direction of the slide plate 17 can be kept horizontal.

[0036] Specifically, such as Figure 7 As shown, a handle 18 is provided at the middle of the upper end of the slide plate 17. The slide plate 17 is movably disposed in the slot 19. A placement slot 15 is provided on the mounting bracket 5 corresponding to the rotating part 8. The rotating part 8 is movably disposed in the placement slot 15. By installing the handle 18 on the slide plate 17, it is convenient for the staff to drive the slide plate 17 to slide.

[0037] In this embodiment: by rotating the rotating component 8, the lead screw 12 can be driven to rotate on the mounting bracket 5, realizing the up and down movement of the lead screw 12, which can drive the horizontal plate 7 to slide inside the fixing groove 20, so that the limiting post 6 installed on the horizontal plate 7 can slide out or slide into the limiting hole 13, realizing the quick replacement of the filter screen 2. By pulling the handle 18, the sliding plate 17 can be driven into the slot 19 to fix the rotating component 8 and prevent external factors from causing the rotating component 8 to rotate.

[0038] The specific solution is as follows: When the filter screen 2 needs to be installed, the operator inserts the fixing frame 14 into the connecting groove 10 to pre-position the filter screen 2. Then, by turning the rotating part 8, the operator can drive the lead screw 12 to move downward, which in turn drives the horizontal plate 7 to slide downward in the fixing groove 20. This allows the limiting post 6 to slide into the limiting hole 13, thus fixing the filter screen 2. This reduces the difficulty of installation, reduces the workload of the operator, and enables the filter screen 2 to be installed quickly, avoiding affecting the normal operation of the cooling fan 3. After the filter screen 2 is installed, the rotating part 8 moves into the placement groove 15. At this time, the slot 19 and the slide plate 17 are on the same horizontal line. By pulling the handle 18, the slide plate 17 can slide inside the horizontal groove 16, which allows the slide plate 17 to be inserted into the slot 19, thus fixing the rotating part 8.
