Description

Technical Field

[0001] This utility model relates to the field of silencer technology, specifically a steam silencer. Background Technology

[0002] A steam silencer is a silencer developed specifically for steam emissions. Boiler steam silencers are mainly used for the effective silencing of steam emissions and other gas emissions from boilers in industries such as power, petroleum, chemical, metallurgy, and textiles. Installing a steam silencer is an important measure to eliminate steam emission noise.

[0003] Currently, most steam silencers in existing technology are integral structures. In order to achieve a good silencing effect on the discharged steam, the internal filling device of the integral silencer is often a complexly shaped ventilation structure. During the steam discharge process, condensate droplets tend to accumulate in the recesses of the ventilation structure. This accumulation cannot be effectively discharged when the steam stops discharging. The accumulation of condensate increases the load on the internal ventilation structure, thereby affecting the overall service life of the device. In addition, the integral structure of the device makes it difficult to easily replace and maintain the internal ventilation structure.

[0004] Therefore, a steam silencer is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies and solve the problem of condensate droplets easily accumulating in the recesses of the ventilation structure during steam discharge, which cannot be effectively discharged when steam discharge stops, the accumulation of condensate water increases the structural strength of the internal ventilation structure, thereby affecting the overall service life of the device. In addition, the integral structural feature of the device makes it difficult to conveniently replace and maintain the internal ventilation structure. Therefore, a steam silencer is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A steam silencer of this utility model includes a base, an exhaust pipe connected to the center of the top of the base, an annular threaded groove opened near the outer peripheral edge of the top of the base, an exhaust hood provided outside the exhaust pipe, the exhaust hood being screwed to the annular threaded groove, a silencer assembly provided between the exhaust hood and the exhaust pipe, the silencer assembly including a filler, a compression ring provided above the filler, the top of the compression ring being fixed to the upper inner wall of the exhaust hood, the bottom surface of the compression ring contacting the top surface of the filler, a hollow support plate provided below the filler, a support column installed at the bottom of the hollow support plate, the support column being made of flexible material, and one end of the support column being fixed to the top of the base.

[0007] Preferably, the top of the base is provided with an annular drainage groove, which is located between the annular threaded groove and the exhaust pipe.

[0008] Preferably, the base has multiple drainage channels inside, and the multiple drainage channels are equally spaced along the outer periphery of the base.

[0009] Preferably, one end of the drainage channel is connected to the annular drainage groove, and the other end of the drainage channel extends to the outside of the base.

[0010] Preferably, the top surface of the exhaust pipe has a mounting groove.

[0011] Preferably, a locking post is fitted inside the locking slot, one end of the locking post is fixedly connected to an elastic telescopic rod, and one end of the elastic telescopic rod is fixedly connected to a lifting shackle.

[0012] Preferably, a lifting seat is externally attached to the lifting shackle, and the lifting seat is fixed to the center of the top surface of the exhaust hood.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the main body of the steam silencer is formed by the cooperation of the base, the exhaust hood, and the silencer assembly. The base is connected to the exhaust channel of the steam pipe with the help of bolts and other fixing structures. The steam is depressurized and silenced by the exhaust pipe, the exhaust hood, and the silencer assembly, and is discharged through the annular threaded groove. The base and the exhaust hood are separate assembly structures, which allows the silencer assembly to be replaced by disassembling the exhaust hood when the silencer assembly is not satisfactory, so as to ensure the silencer effect of the device. Compared with the integrated steam silencer, it has higher operability and reduces the use cost of the steam silencer by replacing the silencer assembly. Attached Figure Description

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figure 1 - Figure 6This utility model provides a steam silencer, including a base 1, an exhaust pipe 11 connected to the center of the top of the base 1, an annular threaded groove 12 formed near the outer edge of the top of the base 1, an exhaust hood 2 provided outside the exhaust pipe 11, the exhaust hood 2 being screwed to the annular threaded groove 12, a silencer assembly 3 provided between the exhaust hood 2 and the exhaust pipe 11, the silencer assembly 3 including a filler 31, a compression ring 32 provided above the filler 31, the top of the compression ring 32 being fixed to the upper inner wall of the exhaust hood 2, the bottom surface of the compression ring 32 contacting the top surface of the filler 31, a hollow support plate 33 provided below the filler 31, a support column 34 installed at the bottom of the hollow support plate 33, the support column 34 being made of flexible material, one end of the support column 34 being fixed to the top of the base 1, the base 1 being fixed after being connected to the steam exhaust pipe of a boiler, etc., steam is discharged through a small hole on the exhaust pipe 11, and is silenced by the pressure reduction of the silencer assembly 3. The exhaust is discharged through small holes on the exhaust hood 2. The annular threaded groove 12 between the exhaust hood 2 and the base 1 is spirally installed, which allows the silencing component 3 to be replaced by disassembling the exhaust hood 2 after the silencing effect of the silencing component 3 is reduced. The filling material 31 of the silencing component 3 plays the main role in reducing pressure and silencing high-pressure steam. It is installed between the base 1, the exhaust pipe 11 and the exhaust hood 2 with the cooperation of the extrusion ring 32, the hollow support plate 33 and the support column 34. The support column 34 itself has a certain degree of flexibility. It provides elastic support for the hollow support plate 33 and the filling material 31 as a whole. When the relative height of the filling material 31 exceeds the gap between the extrusion ring 32 and the hollow support plate 33, the bending of the support column 34 can ensure the installation of the exhaust hood 2 and the base 1. This process can also apply a squeezing and fixing force to the silencing component 3 to prevent the filling material 31 from shaking during the steam pressure reduction and silencing process, thereby increasing the structural stability of the device.

[0027] like Figure 3 As shown, an annular drainage groove 13 is provided on the top of the base 1. The annular drainage groove 13 is located between the annular threaded groove 12 and the exhaust pipe 11. Multiple drainage channels 14 are provided inside the base 1. The multiple drainage channels 14 are equally spaced along the outer periphery of the base 1. One end of the drainage channel 14 is connected to the annular drainage groove 13, and the other end of the drainage channel 14 extends to the outside of the base 1. After the steam comes into contact with the silencing component 3, some of the condensate falls into the annular drainage groove 13 through the hollow support plate 33 and the support column 34, and is discharged from the device with the help of the drainage channel 14. This prevents the steam condensate from accumulating excessively inside the device, which would have an adverse effect on the device's pressure reduction and silencing effect on the steam.

[0028] like Figure 3 , Figure 5 and Figure 6As shown, the top surface of the exhaust pipe 11 is provided with a clamping groove 15. A clamping post 4 is clamped inside the clamping groove 15. One end of the clamping post 4 is fixedly connected to an elastic telescopic rod 41. One end of the elastic telescopic rod 41 is fixedly connected to a lifting clamping ring 42. A lifting seat 21 is clamped outside the lifting clamping ring 42. The lifting seat 21 is fixed to the center of the top surface of the exhaust cover 2. The exhaust cover 2 is lifted by the lifting seat 21 and the lifting clamping ring 42 at one end of the elastic telescopic rod 41 to clamp the clamping post 4. This allows the clamping post 4 to be installed while being clamped to the clamping groove 15 on the exhaust pipe 11 under the elastic compression force of the elastic telescopic rod 41, increasing the structural stability of the exhaust pipe 11. The lifting method between the lifting clamping ring 42 and the lifting seat 21 allows the exhaust cover 2 and the clamping post 4 to rotate relative to each other without affecting each other, ensuring the clamping state of the clamping post 4 and the clamping groove 15 during the rotation installation or disassembly of the exhaust cover 2.

[0029] Working principle: After the base 1 is connected and fixed to the steam exhaust pipe of the boiler, the steam is discharged through the small hole on the exhaust pipe 11, and after being depressurized and silenced by the silencing component 3, it is discharged through the small hole on the exhaust hood 2. The annular threaded groove 12 between the exhaust hood 2 and the base 1 is spirally installed, so that the silencing component 3 can be replaced by disassembling the exhaust hood 2 after the silencing effect of the silencing component 3 is reduced. The filling material 31 of the silencing component 3 plays the main role in depressurizing and silencing high-pressure steam, and cooperates with the extrusion ring 32, the hollow support plate 33 and the support column 34. The exhaust pipe is installed between the base 1, the exhaust pipe 11, and the exhaust hood 2. After the steam comes into contact with the silencer component 3, some of the condensate falls through the perforated support plate 33 and the support column 34 into the annular drainage groove 13, and is discharged from the device with the help of the drainage channel 14. The exhaust hood 2 is hoisted by the hoisting seat 21 and the hoisting ring 42 at one end of the elastic telescopic rod 41, so that the locking column 4 can be installed and simultaneously locked with the locking groove 15 on the exhaust pipe 11 under the elastic extrusion force of the elastic telescopic rod 41, thereby increasing the structural stability of the exhaust pipe 11. The above shows and describes the basic principle, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of this utility model as claimed.
