Description

Technical Field

[0001] This utility model relates to the field of fan application technology, specifically to an explosion-proof and anti-static fan. Background Technology

[0002] Explosion-proof and anti-static fans are fans specifically designed to prevent the risk of fire caused by explosions and static electricity. These fans are commonly used in flammable and explosive environments, such as chemical plants, petrochemical plants, oil depots, and coal mines.

[0003] However, if the junction box of a traditional fan is not sealed, dust, moisture and corrosive gases can enter the electrical components, which may cause short circuits, malfunctions or even fires or explosions.

[0004] Secondly, if the fan lacks an effective air contact area, the fan's air volume and airflow efficiency will decrease, which in turn will lead to a decrease in the fan's working efficiency and an increase in energy consumption.

[0005] Finally, wind turbines without grounding devices may accumulate static electricity, and electrostatic discharge may cause sparks, leading to equipment failure, fire, or even explosion. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figures 1-5An explosion-proof and anti-static fan includes a main body 1, a sealing mechanism, a connecting assembly, and an anti-static assembly. The sealing mechanism includes a mounting box 2, a spring 3, a push plate 4, a sealing box 5, a positioning frame 6, and a fixing member 7. The mounting box 2 is fixedly mounted on the main body 1. The spring 3 is fixedly mounted in the mounting box 2, and its other end is fixedly connected to the push plate 4. The push plate 4 is mounted in the mounting box 2 and slidably connected to the mounting box 2. The sealing box 5 is mounted on the mounting box 2 and detachably connected to the mounting box 2. The positioning frame 6 is mounted on the sealing box 5 and slidably connected to the sealing box 5 and cooperating with the mounting box 2. The fixing member 7 is mounted on the sealing box 5 and rotatably connected to the sealing box 5 and threadedly engaged with the positioning frame 6. The connecting assembly includes an expansion member 8, a wiring box 9, a plug 10, and a connecting wire 11. The expansion member 8 is fixedly mounted on the main body 1. The wiring box 9 is fixedly mounted on the sealing box 5. The plug 10 is cooperating with the wiring box 9, and the connecting wire 11 is fixedly mounted on the plug 10.

[0031] In this embodiment, the sealing mechanism includes a mounting box 2, a spring 3, a push plate 4, a sealing box 5, a positioning frame 6, and a fixing member 7. In use, the wiring on the fan is installed onto the sealing box 5, and then the sealing box 5 is installed onto the mounting box 2. The positioning frame 6 on the sealing box 5 is fixed in position due to the threaded engagement with the fixing member 7. The positioning frame 6 can then be placed into the mounting box 2 through the inlet groove 20. The positioning frame 6 then contacts the push plate 4, which compresses the spring 3 installed in the mounting groove 18, and the limiting rod 19 on the push plate 4 simultaneously slides in the limiting groove. When the positioning frame 6... When the protrusion has completely passed through the groove 20, the positioning frame 6 is rotated. The protrusion on the positioning frame 6 is subjected to the force of the push plate 4 and thus enters the fixing groove. At this time, the position of the positioning frame 6 is fixed. Then, the fixing member 7, which is rotatably installed on the sealing box 5, engages with the screw 26 on the positioning frame 6 through the internal thread 27 on the fixing member 7. Subsequently, under the rotation of the fixing member 7, the sealing box 5 is pressed against the mounting box 2 and the sealing member 23 installed on the sealing box 5 is also pressed, thereby compressing the first sealing gasket 24 and sealing the connection between the sealing box 5 and the mounting box 2 to prevent dust and other debris from entering the mounting box 2.

[0032] In this embodiment, the connecting assembly includes an expansion member 8, a wiring box 9, a plug 10, and a connecting wire 11. During use, due to the presence of the sealing box 5 and the mounting box 2, the fan ventilation holes are partially blocked by the components. Before installing the sealing box 5, the expansion member 8 is installed on the main body 1 to increase the contact area with the outside air. Since the connection between the sealing box 5 and the mounting box 2 is completed, the plug 10 can be inserted into the wiring box 9 at the bottom of the sealing box 5, and the fan can be started by energizing the connecting wire 11.

[0033] In this embodiment, the antistatic component includes a support frame 12, a contact block 13, and a lead wire 14. In use, the contact block 13 is first installed on the support frame 12, and then the main body 1 is fixedly installed on the support frame 12 so that the main body 1 is in contact with the contact block 13. Finally, the static electricity generated when the fan is running is guided to the iron plate 15 by the lead wire 14. At this time, the iron plate 15 has already been connected to the ground by the fixing bolts 16, thereby grounding the static electricity.

[0034] Example 2:

[0035] In summary, during use, firstly, the contact block 13 is installed onto the support frame 12, then the main body 1 is fixedly installed onto the support frame 12, so that the main body 1 contacts the contact block 13. Next, the wiring on the fan is installed onto the sealing box 5, and then the sealing box 5 is installed onto the mounting box 2. At this time, the positioning bracket 6 on the sealing box 5 is fixed in position due to the threaded engagement with the fixing member 7. The positioning bracket 6 can then be inserted into the mounting box 2 through the entry groove 20. The positioning bracket 6 then contacts the push plate 4, which is pressed against the spring 3 installed in the mounting groove 18. Simultaneously, the limiting rod 19 on the push plate 4 slides in the limiting groove. When the protrusion on the positioning bracket 6 completely passes through the entry groove 20, the positioning bracket 6 is rotated. The protrusion on the positioning bracket 6 is subjected to the force of the push plate 4, thus entering the fixing groove. At this time, the positioning bracket 6 is fixed in position. Then, the fixing member 7, which is rotatably installed on the sealing box 5, has its internal thread 2... 7 engages with the screw 26 on the positioning bracket 6. Then, under the rotation of the fixing part 7, the sealing box 5 is pressed against the mounting box 2 and the sealing part 23 installed on the sealing box 5 is also pressed, thereby compressing the first sealing gasket 24 and sealing the connection between the sealing box 5 and the mounting box 2 to prevent dust and other debris from entering the mounting box 2. Due to the presence of the sealing box 5 and the mounting box 2, the ventilation hole of the fan is partially blocked by the components. Before installing the sealing box 5, the expansion part 8 is installed on the main body 1 to increase the contact area with the outside air. Since the connection between the sealing box 5 and the mounting box 2 is completed, the plug 10 can be inserted into the wiring box 9 at the bottom of the sealing box 5, and the fan can be started by energizing the connecting wire 11. Finally, the static electricity generated when the fan is running is guided to the iron plate 15 by the lead wire 14. The iron plate 15 has already been connected to the ground by the fixing bolt 16, thereby grounding the static electricity.

[0036] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
