Description

Technical Field

[0001] The utility model relates to the field of filter joints, in particular to a joint structure of a coalescence filter. Background Art

[0002] The natural gas coalescing filter is mainly used as the pre-module of the power plant pressure regulating station and is the last filter of the gas turbine in the power plant.

[0003] At present, a Chinese utility model with the announcement number CN214635060U discloses a small coalescing filter, including a filter body, the filter body is composed of a shell and a flange cover; the shell is symmetrically provided with a natural gas inlet and a natural gas outlet near the flange cover on both sides; a baffle and a mounting plate are installed in the shell, the baffle is installed near the natural gas inlet, the mounting plate is horizontally installed near the bottom of the shell, one side of the mounting plate is connected to the bottom of the vertical section of the baffle, and the other side is connected to the inner wall of the shell where the natural gas outlet is installed; the shell, the flange cover, the baffle and the mounting plate form a groove, and a filter element is installed in the groove. In the above manner, the utility model provides a small coalescing filter, which has a simple structure, not only has all the functions of the original coalescing filter, but also can be directly connected to the pipeline, and is suitable for small flow branches and limited on-site space.

[0004] In summary, the above disclosed coalescing filter includes a natural gas inlet and a natural gas outlet, and the inlet and the outlet are actually the joint structure of the coalescing filter;

[0005] It can be seen from the above-mentioned prior art that the joint structure adopted by the above-mentioned prior art is a flange structure. When the joint is used for installation, there are problems such as complex bolt connections and inconvenient assembly and disassembly; and it does not have the function of adjusting the natural gas flow space, resulting in the inability to adjust the input or output pressure of the natural gas. If the input pressure is too small, the gas will not be able to penetrate the filter element, resulting in ineffective filtration. If the input pressure is too large, the gas will penetrate the filter element too quickly, resulting in excessive or too fast filtration of the filter element.

[0006] In order to solve the above problems, we propose a joint structure of a coalescing filter. Utility Model Content

[0007] The utility model aims to provide a joint structure of a coalescing filter, which has the advantages of being easy to install and having the function of regulating gas pressure.

[0008] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a joint structure of a coalescing filter, comprising an air inlet pipe and an air supply pipe, the air inlet pipe having a sealing head integrally processed at one end close to the air supply pipe, the surface sleeve of the air inlet pipe being provided with a threaded female joint, the internal thread of the threaded female joint being connected with a threaded sub-joint integrally processed with the air supply pipe; a sliding groove is provided at the bottom of the air inlet pipe, the bottom of the air inlet pipe is connected with a guide bin, a sealing sleeve is provided inside the guide bin, an air baffle is fixedly sleeved inside the sealing sleeve, an adjusting bolt is provided at the bottom of the air baffle, the surface of the adjusting bolt is threadedly connected to the bottom of the guide bin.

[0009] By adopting the above technical scheme, by setting a sealing head, a threaded female joint and a threaded sub-joint, the threaded female joint and the threaded sub-joint are threadedly connected to complete the docking work, and the installation is more convenient; by setting an air intake pipe, a guide bin, a sliding groove, an air baffle, a sealing sleeve and an adjusting bolt, and by adjusting the distance between the air baffle and the top of the inner cavity of the air intake pipe, the space through which the gas in the inner space of the air intake pipe can pass can be reduced or enlarged, thereby realizing the regulation of the gas pressure.

[0010] The utility model is further configured as follows: a sealing ring 1 is sleeved on the surface of the air inlet pipe, one side of the sealing ring 1 contacts the sealing head, and the other side of the sealing ring 1 contacts the threaded female joint.

[0011] The above technical solution is adopted, through the provision of a sealing ring 1, to reduce the seal between the threaded female joint and the sealing head to avoid gas leakage.

[0012] The utility model is further configured as follows: a sealing ring 2 is provided on a side of the sealing head away from the sealing ring 1, and two sides of the sealing ring 2 are respectively in contact with the threaded sub-joint and the sealing head.

[0013] The above technical solution is adopted, through the provision of the sealing ring 2, to seal between the threaded sub-joint and the sealing head to avoid gas leakage.

[0014] The utility model is further configured as follows: a bearing is embedded in the air baffle, and the inside of the bearing is rotatably sleeved with the surface of the adjusting bolt.

[0015] The above technical solution is adopted, through the setting of the bearing, to assist the adjusting bolt in rotating, so that the adjusting bolt can be downward or upward through the threaded connection with the guide bin.

[0016] The utility model is further configured as follows: the bottom end of the adjusting bolt penetrates through the bottom of the guide bin and is bolted with a handle.

[0017] By adopting the above technical solution, the user can rotate the adjusting bolt conveniently through the setting of the turning handle, thereby reducing the difficulty of rotating the cylindrical adjusting bolt.

[0018] The utility model is further configured as follows: the length of the guide bin close to the air inlet pipe is the same as the length of the bottom of the air inlet pipe, and the interior of the guide bin is sealingly and slidably connected with the surface of the sealing sleeve.

[0019] By adopting the above technical solution, through the surface sealing sliding connection of the guide bin and the sealing sleeve, when the adjusting bolt rotates, the air baffle plate connected by the bearing and the adjusting bolt will not rotate but can only move up and down, thereby making it convenient for personnel to adjust the position of the air baffle plate and the sealing sleeve through the adjusting bolt.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The utility model is connected with the gas delivery pipe by setting a threaded sub-joint, and the threaded female joint is set on the surface of the air inlet pipe and is threadedly connected with the threaded sub-joint, thereby replacing the installation structure of the traditional flange. The connection can be completed by only threading the threaded female joint and the threaded sub-joint, without the cumbersome process of installing multiple screws of the traditional flange, which is easy to install, and the overall operation is simple and convenient;

[0022] 2. The utility model arranges a sealing sleeve and an air baffle plate inside the air intake pipe, and arranges an adjusting bolt and a guide chamber threaded connection. When the adjusting bolt rotates clockwise or counterclockwise, the sealing sleeve and the air baffle plate can be pulled to move up and down, thereby adjusting the space between the sealing sleeve and the top of the inner cavity of the air intake pipe. When the gas pressure is too high, the guide chamber can be adjusted to be away from the top of the inner cavity of the air intake pipe to expand the gas delivery space and realize gas pressure reduction. When the gas pressure is too low, the guide chamber can be adjusted to be close to the top of the inner cavity of the air intake pipe to reduce the space through which the gas can pass, thereby realizing the pressure boosting function, thereby ensuring that the gas is filtered by the filter element of the filter under stable pressure after entering the filter.

[0033] refer to Figure 1 , Figure 2 and Figure 3 A sealing ring 11 is sleeved on the surface of the air inlet pipe 1, one side of the sealing ring 11 contacts the sealing head 3, and the other side of the sealing ring 11 contacts the threaded female joint 4. The setting of the sealing ring 11 is used to reduce the seal between the threaded female joint 4 and the sealing head 3 to avoid gas leakage.

[0034] refer to Figure 1 , Figure 2 and Figure 3 A sealing ring 2 12 is provided on the side of the sealing head 3 away from the sealing ring 1 11. The two sides of the sealing ring 2 12 are respectively in contact with the threaded sub-joint 5 and the sealing head 3. The setting of the sealing ring 2 12 is used to seal between the threaded sub-joint 5 and the sealing head 3 to prevent gas leakage.

[0035] Brief description of the use process: When in use, weld the threaded sub-joint 5 to the gas pipe 2, weld the gas pipe 2 to the gas supply device, and weld the air inlet pipe 1 to the filter;

[0036] During installation, the threaded sub-joint 5 and the threaded female joint 4 are aligned, and the threaded female joint 4 is rotated to make the threaded female joint 4 and the threaded sub-joint 5 threadedly connected. When the threaded female joint 4 cannot be rotated, the side of the threaded sub-joint 5 close to the sealing head 3 will contact the second sealing ring 12, and at the same time, the side of the sealing head 3 close to the threaded sub-joint 5 will also contact the second sealing ring 12, thereby forming a seal;

[0037] The threaded female connector 4 will also contact the side of the sealing head 3 away from the sealing ring 12, thereby forming a second layer of sealing. The threaded female connector 4 and the threaded sub-connector 5 are threadedly connected and fixed to complete the installation.

[0038] If disassembly is required, the threaded female connector 4 and the threaded sub-connector 5 can be separated.

[0041] refer to Figure 5 A bearing 13 is embedded in the air baffle 9, and the interior of the bearing 13 is rotatably sleeved with the surface of the adjusting bolt 10. The bearing 13 is arranged to assist the adjusting bolt 10 in rotating motion, so that the adjusting bolt 10 can be downward or upward through the threaded connection with the guide bin 7.

[0042] refer to Figure 1 , Figure 2 and Figure 5 The bottom end of the adjusting bolt 10 passes through the bottom of the guide bin 7 and is bolted with a handle 14. The setting of the handle 14 makes it easy for the user to rotate the adjusting bolt 10, thereby reducing the difficulty of rotating the cylindrical adjusting bolt 10.

[0043] refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The length of the guide bin 7 close to the side of the air intake pipe 1 is the same as the length of the bottom of the air intake pipe 1. The interior of the guide bin 7 is sealed and slidably connected to the surface of the sealing sleeve 8. Through the surface sealing and sliding connection between the guide bin 7 and the sealing sleeve 8, when the adjusting bolt 10 rotates, the air baffle 9 connected through the bearing 13 and the adjusting bolt 10 will not rotate and can only move up and down, so that it is convenient for personnel to adjust the position of the air baffle 9 and the sealing sleeve 8 through the adjusting bolt 10.

[0044] Brief description of the use process: When the gas delivery pressure is too low, the adjusting bolt 10 is rotated clockwise so that the adjusting bolt 10, under the effect of the threaded connection with the guide bin 7, drives the air baffle 9 and the sealing sleeve 8 to approach the top of the inner cavity of the air inlet pipe 1, thereby reducing the ventilated space between the sealing sleeve 8 and the top of the inner cavity of the air inlet pipe 1, and then the gas passes through a smaller space to achieve the purpose of pressurization;

[0045] If the gas pressure is too high, rotate the adjusting bolt 10 counterclockwise to expand the top space of the sealing sleeve 8 and the inner cavity of the intake pipe 1, thereby increasing the gas circulation space, so that the high-pressure gas can be dispersed in a large space when circulating, thereby achieving the purpose of reducing pressure;

[0046] After passing through the air intake pipe 1, the gas enters the filter and is filtered by the filter element inside the filter.

[0047] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
