Technical Field

[0001] This utility model relates to the technical field of spark-proof silencers, specifically a spark-proof silencer. Background Technology

[0002] The exhaust gases emitted by the engines of oilfield workover rigs may contain sparks, especially under heavy loads or when engine malfunctions such as carbon buildup or afterburner occur. This can easily ignite an oil and gas fire. Furthermore, the high-temperature surfaces of the exhaust pipes, when contaminated with oil, can also easily ignite. Therefore, spark-proof silencers are necessary. However, if the pipe connections of existing spark-proof silencers are not sealed, exhaust gases may leak through the gaps, affecting subsequent spark-proofing operations. Therefore, designing a spark-proof silencer is crucial. For example: Chinese Patent Publication No. CN221074405U discloses that, compared with the prior art, the beneficial effects of this utility model are as follows: This spark extinguishing silencer with a cleanable function performs multiple noise reduction treatments on the exhaust gas through the first, second, third, and fourth chambers, resulting in good noise reduction performance; it performs multiple fire extinguishing treatments on the sparks in the exhaust gas through the air inlet pipe, the first baffle, and the second baffle, resulting in good spark extinguishing performance; and it uses a spray valve to spray the inner wall of the first chamber, the first baffle, the first silencer pipe, and the second baffle inside the silencer cylinder to wash and clean the solid particles inside the silencer cylinder, and the solid particles inside the silencer cylinder can be discharged into the ash collection tank for regular cleaning, extending the service life of the silencer.

[0003] Based on existing solutions and actual production and processing, current spark-proof silencers still have some problems, such as: While existing spark-proof silencers can extend the service life of the silencer, there is a high possibility that exhaust gas may leak from the gaps, affecting subsequent spark-proof silencing operations. Therefore, we propose a spark-proof silencer to solve the problems mentioned above. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1-5 The present invention provides the following technical solution: A spark-proof silencer includes: a first sleeve 1, a second sleeve 2, an air inlet pipe 3, a sound-breaking plate 4, an air outlet pipe 5, a connecting rod 14, a support frame 15, a first limiting plate 16, a vertical rod 17, a baffle body 18, a driven sleeve 19, a fan blade body 20, a connecting hole 21, a reinforcing plate 22, a second limiting plate 23, a positioning block 24, and a locking plate 25.

[0018] Specific examples Figure 1 and Figure 4 As shown, firstly, the first sleeve 1 is placed vertically, with the part connecting the first sleeve 1 to the fixing plate 25 placed on the upper side. The fixing plate 25 is placed horizontally. The inner diameter of the first sleeve 1 is measured, and an asbestos layer 6 of suitable diameter is selected. The asbestos layer 6 has a cylindrical structure. After aligning the asbestos layer 6 with its opening, it is inserted from top to bottom. Friction occurs between the outer wall of the asbestos layer 6 and the inner wall of the first sleeve 1, and a sliding connection is established between the asbestos layer 6 and the first sleeve 1. Until the bottom end of the asbestos layer 6 contacts the first sleeve 1, at which point the asbestos layer 6 is completely inserted into the interior of the first sleeve 1. Next, the part of the second sleeve 2 connected to the vent pipe 5 is placed vertically as the lower end of the second sleeve 2. The vent pipe 5 is aligned with the upper opening of the second sleeve 2 and placed from top to bottom. Friction occurs between the outer wall of the second sleeve 2 and the inner wall of the asbestos layer 6, and the second sleeve 2 and the asbestos layer 6 are slidably connected. A positioning block 2 is provided at the outer end of the vent pipe 5. 4. The positioning block 24 is set at an equal angle to the center of the air outlet pipe 5. When the positioning block 24 is engaged with the bottom end of the first sleeve 1 and the bottom end face of the second sleeve 2 is in contact with the inner bottom end of the first sleeve 1, the pressing of the second sleeve 2 is stopped. At this time, the connecting plate 7 set at the outer end of the second sleeve 2 is in contact with the clamping plate 25, and the bottom end of the connecting plate 7 is in contact with the upper end of the clamping plate 25. The connecting bolt 8 is vertically screwed on at the connection between the connecting plate 7 and the clamping plate 25. The outer end of the connecting bolt 8 is provided with a threaded structure, and the connecting bolt 8 is set at an equal angle to the center of the connecting plate 7. When the connecting bolt 8 is tightened, the connection gap between the connecting plate 7 and the clamping plate 25 is shortened. Under the action of the connecting bolt 8, the connecting plate 7 and the clamping plate 25 are firmly connected. An asbestos layer 6 is provided between the first sleeve 1 and the second sleeve 2. The asbestos layer 6 serves as an interlayer to provide heat insulation, so that the surface of the first sleeve 1 is kept at a low temperature, which facilitates the heat insulation function of the spark-proof silencer.

The upper end of the driven sleeve 19... A baffle body 18 is provided, which is placed horizontally. When the driven sleeve 19 rotates, sliding friction occurs between the bottom end of the baffle body 18 and the top end of the driven sleeve 19. At the same time, sliding friction occurs between the bottom end of the baffle body 18 and the fan blade body 20 and the top end of the air-breaking and sound-breaking plate 4 located inside the second sleeve 2. After the exhaust gas comes into contact with the air-breaking and sound-breaking plate 4, a spark elimination operation is performed. Meanwhile, the exhaust gas reaches the middle of the second sleeve 2 through the interior of the connecting hole 21. The connecting hole 21 is located on the air-breaking and sound-breaking plate 4. The air and sound breaking plates 4 are evenly distributed, and a triangular reinforcing plate 22 is installed at the bottom. The inner end of the reinforcing plate 22 is connected to the outer end of the vertical rod 17. The reinforcing plate 22 is set at an equal angle about the center of the air and sound breaking plate 4. After repeating the above operation, the exhaust gas reaches the bottom of the second sleeve 2 and is discharged through the exhaust pipe 5. The upper and lower ends of the vertical rod 17 pass through the interior of the support frame 15. The support frame 15 has a ring-shaped structure, and the outer end of the support frame 15 is provided with connecting rods 1 distributed at equal angles. 4. The outer end of the connecting rod 14 is connected to the inner end of the second sleeve 2. The upper end of the support frame 15 of the upper group is equipped with the first limiting plate 16, and the lower end of the support frame 15 of the lower group is equipped with the second limiting plate 23. The baffle body 18 is parallel to the first limiting plate 16 and the second limiting plate 23.
