Description

Technical Field

[0001] This utility model relates to the field of vacuum pump technology, and in particular to a multifunctional silencer. Background Technology

[0002] In the current industrial technology field, vacuum pumps, as important industrial equipment, are widely used in various industrial production and experimental environments. Vacuum pumps generate significant noise during operation, which not only poses a potential threat to the health of operators but may also disrupt the normal work order of the surrounding environment. Therefore, the application of vacuum pump silencers is particularly important.

[0003] Currently, vacuum pump silencers on the market mainly focus on noise reduction. Through specific acoustic design and material selection, they effectively reduce the noise level of vacuum pumps during operation. However, these silencers are relatively simple in function, only meeting the basic requirements of noise control, while neglecting the monitoring of other important information during the operation of vacuum pumps.

[0004] The lack of real-time monitoring of key parameters such as vacuum pump operating status, exhaust status, and internal pressure makes it difficult for operators to intuitively understand the working status of the vacuum pump and accurately judge the operating status of the equipment. This, to some extent, limits the flexible application of vacuum pumps in complex industrial environments, thereby affecting the efficiency of equipment maintenance management and troubleshooting. Utility Model Content

[0005] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0006] Specifically, the technical problem to be solved by this utility model is to provide a multifunctional silencer to address the technical problem that current silencers are relatively simple in function, only meeting the basic needs of noise control, while neglecting the monitoring of other important information during the operation of vacuum pumps.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A multifunctional silencer includes a silencer body, a KF25 tee fixed to the outlet end of the silencer body, an outlet pipe fixed to the end of the KF25 tee away from the silencer body, a pressure gauge installed at the bypass end of the KF25 tee, a KF25 baffle valve fixed at the bypass end of the KF25 tee, a KF25 quick-connect coupling installed at the upper end of the KF25 baffle valve, a gas flow meter detachably installed at the end of the KF25 quick-connect coupling away from the KF25 baffle valve, and an outlet pipe fixed to the outlet end of the gas flow meter.

[0009] The muffler body includes a housing, inside which a set of muffler bodies are placed, and a set of multiple muffler bodies are placed inside the housing in a horizontally connected manner.

[0010] As an improved technical solution, the KF25 tee has a threaded hole at the upper middle pipe end, and the KF25 tee can be detachably connected to the pressure gauge through the threaded hole.

[0011] As an improved technical solution, a connecting pipe is detachably installed between the outlet end of the KF25 quick connector and the inlet end of the gas flow meter.

[0012] As an improved technical solution, the connection between the KF25 baffle valve and the KF25 quick-connect coupling, as well as the connection between the KF25 baffle valve and the KF25 tee, are all equipped with clamps with sealing rings for sealing and locking.

[0013] As an improved technical solution, the silencing body includes a horn-shaped retaining plate welded inside the outer shell. A crossbar is welded to the small end of the horn-shaped retaining plate. A dragon blade is welded to the outer wall of the crossbar. Silencing cotton is placed on the outer wall of the crossbar and inside the cavity of the dragon blade. A drainage cavity is opened at one end of the crossbar near the horn-shaped retaining plate. Four feeding cavities are opened on the peripheral surface of the crossbar near the horn-shaped retaining plate, and the feeding cavities are connected to the drainage cavities.

[0014] As an improved technical solution, the outer wall surface of the trumpet-shaped retaining plate is fixed with sound-absorbing cotton.

[0015] As an improved technical solution, a connecting pipe is welded to the through holes at both ends of the outer shell, and a flange is welded to the end of the connecting pipe away from the outer shell.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. This utility model has two operating states, which can be switched by switching the KF25 baffle valve. When the KF25 baffle valve is closed, the pressure of the vacuum pump can be monitored. When the KF25 baffle valve is open, the pumping speed of the vacuum can be monitored. While silencing noise, the pumping speed and pressure of the vacuum pump can also be monitored in real time, which is convenient for accurately judging the operating status of the equipment and making flexible adjustments.

[0018] 2. In this utility model, the airflow passes through multiple silencer bodies in sequence, silencing the noise of the vacuum pump multiple times. This repeated silencing helps to improve the silencing effect. Furthermore, the guide of the crossbar and the auger blades prolongs the time the airflow stays inside the outer shell, increasing the contact time between the airflow and the second silencing cotton, thus improving the silencing effect of the second silencing cotton on the airflow. At the same time, the folding of the trumpet-shaped retaining plate and its cooperation with the first silencing cotton further enhance the silencing effect on the airflow. These multiple silencing measures effectively improve the silencing effect of the silencer body. Attached Figure Description

[0030] like Figures 1 to 4 As shown in the figure, this embodiment provides a multi-functional muffler. This multi-functional muffler includes a muffler body 1, and the air inlet end of the muffler body 1 is fixed to the exhaust port of the vacuum pump. A KF25 tee 2 is fixed to the air outlet end of the muffler body 1. An air outlet pipe 9 is fixed to the end of the KF25 tee 2 away from the muffler body 1. A pressure gauge 3 is installed at the bypass end of the KF25 tee 2. A KF25 baffle valve 4 is fixed to the bypass end of the KF25 tee 2. A KF25 quick connector 5 is installed at the upper end of the KF25 baffle valve 4. A gas flow meter 7 is detachably installed at the end of the KF25 quick connector 5 away from the KF25 baffle valve 4. An air outlet pipe 10 is fixed to the air outlet end of the gas flow meter 7.

[0031] The silencer body 1 includes a housing 11, inside which a set of silencer bodies 12 are placed. A set of multiple silencer bodies 12 are placed inside the housing 11 in a horizontally connected manner. When airflow enters the silencer body 1, the airflow will pass through the multiple silencer bodies 12 in sequence, and the noise of the vacuum pump will be silenced multiple times. Repeating the silencing multiple times helps to improve the silencing effect.

[0032] There are two monitoring modes, which can be switched by switching the KF25 baffle valve 4. When the KF25 baffle valve 4 is closed, the pressure of the vacuum pump can be monitored. When the KF25 baffle valve 4 is open, the pumping speed of the vacuum can be monitored. While silencing the noise, the pumping speed and pressure of the vacuum pump can also be monitored in real time, which makes it easy to accurately judge the operating status of the equipment and make flexible adjustments.

[0033] like Figures 1 to 2 As shown in the figure, in this embodiment, a threaded hole is provided at the upper middle pipe end of the KF25 tee 2, and the KF25 tee 2 is detachably connected to the pressure gauge 3 through the threaded hole.

[0034] like Figures 1 to 2 As shown in the figure, in this embodiment, a connecting pipe 6 is detachably installed between the outlet end of the KF25 quick connector 5 and the inlet end of the gas flow meter 7.

[0035] like Figures 3 to 4 As shown in the figure, in this embodiment, the connection between the KF25 baffle valve 4 and the KF25 quick connector 5, as well as the connection between the KF25 baffle valve 4 and the KF25 tee 2, are both equipped with a sealing ring clamp 8 for sealing and locking. The sealing ring clamp 8 can be used to seal and lock, thereby improving the sealing performance of the entire pipeline.

[0036] like Figures 3 to 4 As shown, the silencing body 12 includes a horn-shaped retaining plate 121 welded inside the outer shell 11. A crossbar 125 is welded to the small end of the horn-shaped retaining plate 121. A dragon blade 126 is welded to the outer wall of the crossbar 125. Silencing cotton 127 is disposed on the outer wall of the crossbar 125 and inside the cavity of the dragon blade 126. A drain cavity 123 is opened at one end of the crossbar 125 near the horn-shaped retaining plate 121. Four feeding cavities 124 are opened on the peripheral surface of the crossbar 125 near the horn-shaped retaining plate 121. The interior of 124 is connected to the interior of the discharge chamber 123. When the airflow is silenced by the silencing body 12, the guide of the crossbar 125 and the auger blade 126 will prolong the time that the airflow stays inside the outer shell 11, increase the contact time between the airflow and the second silencing cotton 127, and improve the silencing effect of the second silencing cotton 127 on the airflow. At the same time, when the airflow completely passes through the auger blade 126, it will collide with the trumpet-shaped retaining plate 121. The airflow will turn back and pass through the feed chamber 124 and the discharge chamber 123 to enter the next section of the silencing body 12 for silencing.

[0037] like Figures 3 to 4 As shown, a sound-absorbing cotton 122 is fixed on the outer wall of the trumpet-shaped retaining plate 121. The folding of the trumpet-shaped retaining plate 121 and the cooperation of the sound-absorbing cotton 122 will further improve the sound-absorbing effect on the airflow. The multiple sound-absorbing measures effectively improve the sound-absorbing effect of the silencer body 1.

[0038] like Figure 3 As shown, a connecting pipe 13 is welded to the through holes at both ends of the outer shell 11, and a flange 14 is welded to the end of the connecting pipe 13 away from the outer shell 11.

[0039] During use, the air inlet of the muffler body 1 is installed at the exhaust port of the vacuum pump. Under normal operating conditions:

[0040] Closing 24 isolates the KF25 tee 2 from the connecting air pipe 6. The vacuum pump exhaust enters the KF25 tee 2 after being silenced by the silencer body 1. The pressure gauge 3 monitors and displays the pressure in the pipe. Finally, the gas is discharged from the outlet pipe 9. This is how the pressure is monitored and displayed.

[0041] Another usage scenario: Block the outlet pipe 9 with a blind flange and open the KF25 baffle valve 4. At this time, the KF25 tee 2 is connected to the connecting pipe 6. After the vacuum pump exhausts, the gas is silenced by the silencer body 1 and then enters the gas flow meter 7 through the KF25 tee 2, KF25 baffle valve 4, KF25 quick connector 5 and connecting pipe 6. Finally, it is discharged through the outlet pipe 10. The gas flow rate can be measured when the gas passes through the gas flow meter 7.

[0042] When the airflow enters the interior of the muffler body 1, the airflow will pass through multiple muffler bodies 12 in sequence;

[0043] When noise is silenced by the silencing body 12, the airflow stays inside the outer shell 11 for a longer time due to the guidance of the crossbar 125 and the dragon blades 126.

[0044] At the same time, after the airflow completely passes through the dragon blade 126, it will collide with the trumpet-shaped retaining plate 121. The airflow will then return and pass through the feed chamber 124 and the discharge chamber 123 to enter the next section of the silencing body 12 for silencing.

[0045] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
