Description

Technical Field

[0001] This utility model relates to the field of screw pumps, and in particular to a water-cooled silencer for screw pumps. Background Technology

[0002] A screw pump is a positive displacement pump that transports liquids through the rotation of a screw. It is widely used in industries such as petroleum, chemical, food, and pharmaceutical. It is suitable for transporting high-viscosity media, media containing solid particles, or media requiring stable transport. It has advantages such as stable transport and strong self-priming ability.

[0003] Screw pumps have an air outlet and generate significant noise during actual use. To reduce noise, a silencer is usually installed at the air outlet. Existing methods mostly involve placing sound-absorbing cotton inside the silencer structure to achieve the purpose of noise reduction. However, in actual use, the gas discharged from the screw pump is at a high temperature, which can cause the sound-absorbing cotton to deform under high-temperature burning, and then clump together and fail, resulting in poor durability. Further optimization and improvement are needed. Utility Model Content

[0004] To further improve durability, this application provides a water-cooled silencer for a screw pump.

[0005] This application provides a water-cooled silencer for a screw pump, which adopts the following technical solution:

[0006] A water-cooled silencer for a screw pump includes a cooling box and a silencer body. The silencer body has a silencer pipe inside, and a plurality of through silencer holes are opened on the side wall of the silencer pipe. The silencer body has partitions inside, and the partitions are spaced apart along the length of the silencer body, forming a sound insulation chamber between adjacent partitions.

[0007] Optionally, the cooling box is provided with a cooling pipe, which has an inlet and an outlet, both of which extend from the side wall of the cooling box.

[0008] Optionally, a vent pipe is provided inside the cooling box, one end of which is connected to the interior of the silencer body, and the cooling pipe is spirally wound around the vent pipe.

[0009] Optionally, the cooling box is provided with an air inlet, the height of which is higher than the end of the vent pipe away from the muffler body.

[0010] Optionally, the vent pipe is arranged vertically, and the air inlet is arranged horizontally.

[0011] Optionally, one end of the vent pipe is detachably connected to the silencer body.

[0012] Optionally, the end of the vent pipe extending out of the cooling box has a connecting flange for connection to the silencer body flange.

[0013] Optionally, the silencer pipe is arranged vertically and passes through each partition.

[0014] Optionally, the partition plate has a through hole for the silencer pipe to pass through, and there is a gap between the inner wall of the through hole and the silencer pipe.

[0015] Optionally, the bottom of the cooling tank is provided with a drain port, and the drain port is provided with a plug.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. Abandoning the traditional sound insulation cotton method, it adopts the sound insulation holes on the sound insulation tube to achieve good sound insulation. Furthermore, the sound insulation body is divided into multiple sound insulation chambers by the help of partitions. Multiple sound insulation chambers achieve the purpose of step-by-step sound insulation, resulting in better sound insulation effect. In addition, the sound insulation tube method has better durability and effectively extends the service life of the silencer.

[0018] 2. The cooling box can effectively cool the incoming high-temperature gas and also serve to collect moisture and impurities. The moisture and impurities can be discharged directly through the drain port, which is simple and convenient. After being cooled, the high-temperature gas enters the muffler body to achieve noise reduction, effectively preventing the exhaust from burning the muffler pipe and the muffler body, thereby improving durability.

[0019] 3. The cooling medium enters through the inlet and exits through the outlet, realizing the circulation of the cooling medium, which can remove heat in time and achieve a more efficient cooling effect. In addition, the cooling pipe is spirally wound on the vent pipe, making the cooling area more uniform and comprehensive, thus achieving a better cooling effect.

[0020] 4. Because the height of the air inlet is higher than the end of the vent pipe that is furthest from the muffler body, the high-temperature gas will not be discharged directly from the vent pipe when it enters the cooling box. Instead, it needs to be cooled for a period of time before being discharged into the muffler body through the vent pipe. This prolongs the travel path and time of the high-temperature gas in the cooling box, ultimately improving the cooling effect. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] A water-cooled silencer for a screw pump, such as Figure 1 As shown, it includes a cooling box 1 and a silencer body 2. The silencer body 2 is connected to the top of the cooling box 1 and the two are internally interconnected. An air inlet 3 is provided on the side wall of the cooling box 1. The air inlet 3 is horizontally set and is used to communicate with the air outlet of the screw pump. An air outlet 4 is opened on the top of the silencer body 2. In actual use, the gas discharged by the screw pump enters the cooling box 1 through the air inlet 3 for cooling, and then flows into the silencer body 2 to achieve noise reduction before finally being discharged from the air outlet 4, thereby effectively achieving the purpose of noise reduction.

[0028] like Figures 1-3 As shown, a vertically arranged vent pipe 5 is provided inside the cooling box 1. The bottom end of the vent pipe 5 is connected to the interior of the cooling box 1, and the top end of the vent pipe 5 extends out of the cooling box 1 and is used to connect with the muffler body 2. The vent pipe 5 enables the interconnection between the cooling box 1 and the muffler body 2. In addition, a cooling pipe 6 is provided inside the cooling box 1. The cooling pipe 6 is spirally wound around the vent pipe 5. The cooling pipe 6 is made of copper, which has better thermal conductivity. Cooling medium is introduced into the cooling pipe 6. The cooling pipe 6 has an inlet 7 and an outlet 8, both of which extend from one side of the cooling box 1. In this embodiment, the height of the inlet 7 is lower than the height of the outlet 8. The cooling medium enters through the inlet 7 and exits through the outlet 8, realizing the circulation of the cooling medium. This can remove heat in time and achieve a more efficient cooling effect. Furthermore, the cooling pipe 6 is spirally wound around the vent pipe 5, making the cooling area more uniform and comprehensive, thereby achieving a better cooling effect.

[0029] like Figures 1-3 As shown, the height of the air inlet 3 is higher than the end of the vent pipe 5 furthest from the muffler body 2. When the high-temperature gas enters the cooling box 1, it will not be discharged directly from the vent pipe 5, but will need to be cooled for a period of time before being discharged into the muffler body 2 through the vent pipe 5. This prolongs the travel path and time of the high-temperature gas in the cooling box 1, ultimately improving the cooling effect. In this embodiment, the height of the inlet 7 is lower than the height of the outlet 8. This way, the high-temperature gas will flow downwards after entering the cooling box 1 through the air inlet 3 before entering the vent pipe 5. The lower height of the inlet 7 can achieve priority cooling of the lower position. The upward and downward counterflow of the two can achieve a better cooling effect.

[0030] like Figure 2 and Figure 3 As shown, a drain port 9 is provided at the bottom of the cooling tank 1, and a plug 10 is provided at the drain port 9 for detachable connection. In actual use, the water and impurities generated will be deposited at the bottom of the cooling tank 1. The water can be drained by simply opening the plug 10. The operation is simple and convenient. The plug 10 is threaded to the drain port 9. It can be installed and removed by simply rotating the plug 10.

[0031] like Figure 2 and Figure 3 As shown, the interior of the silencing body 2 is hollow. A connecting pipe 11 is provided at the bottom of the silencing body 2. The top end of the connecting pipe 11 is located inside the silencing body 2, and the bottom end of the connecting pipe 11 extends out of the silencing body 2. A connecting flange 12 is provided at the opposite end of the connecting pipe 11 and the vent pipe 5 to achieve flange connection, so that the cooling box 1 and the silencing body 2 can be disassembled. The connecting pipe 11 and the silencing body 2, as well as the vent pipe 5 and the cooling box 1, are all fixed by welding.

[0032] like Figure 2 and Figure 3 As shown, a vertical silencing pipe 13 is provided inside the silencing body 2. An air outlet pipe 14 is fixed to the top of the silencing pipe 13, and an air outlet 4 is provided on the air outlet pipe 14. Multiple through silencing holes 15 are evenly distributed on the side wall of the silencing pipe 13. At the same time, a horizontal partition 16 is provided inside the silencing body 2. Multiple partitions 16 are distributed at intervals along the vertical direction of the silencing body 2, and sound insulation chambers 17 are formed between adjacent partitions 16. The silencing pipe 13 passes through the middle of the partition 16. In this embodiment, both the partition 16 and the silencing pipe 13 are made of carbon steel. In other embodiments, stainless steel can also be used. The silencing holes 15 on the silencing pipe 13 are used to achieve good silencing. The partitions 16 are used to divide the silencing body 2 into multiple sound insulation chambers 17. Multiple sound insulation chambers 17 achieve the purpose of silencing in stages, resulting in better silencing effect. In addition, the silencing pipe 13 has better durability and effectively extends the service life of the silencer.

[0033] like Figure 2 and Figure 3As shown, a through hole 18 is provided in the center of the partition 16 for the silencer pipe 13 to pass through. In this embodiment, there is a gap between the inner wall of the through hole 18 and the outer wall of the silencer pipe 13, that is, the diameter of the through hole 18 is slightly larger than the outer diameter of the silencer pipe 13. In this way, in actual use, some high-temperature gas can flow upward through this gap, improving the flow efficiency of high-temperature gas in the silencer body 2. In other embodiments, the through hole 18 can be adapted to the silencer pipe 13, and the silencer pipe 13 can be welded and fixed to the partition 16. This makes the partition 16, the silencer pipe 13 and the silencer body 2 form a fixed whole, which ensures the structural strength and stability. The partition 16 can play an auxiliary supporting and fixing role for the silencer pipe 13, realizing the multi-purpose function of the partition 16.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
