Description

Technical Field

[0001] The utility model discloses a low-pressure gas pressurizing device with a multi-pressurizing structure, belonging to the field of measurement inspection. Background Art

[0002] A supercharger is a device used to increase gas pressure. It is usually used to convert low-pressure gas into high-pressure gas for use in environments that require high pressure. It usually includes a boost chamber. The supercharger uses some form of mechanical or fluid power principle to increase the pressure of the gas. The core-type mechanical supercharger uses an impeller (a device similar to a rotor) to provide power to suck air into a narrow compressor housing at high speed.

[0003] In the prior art, since the supercharger can be used in a variety of places and can pressurize low-pressure gas, when the low-pressure gas is pressurized, the supercharger usually includes a supercharging chamber inside. However, the main function of the supercharger is to increase the air flow entering the engine, which requires the engine to be in a high-load state for a long time, and there may be problems such as insufficient power and increased fuel consumption, which shortens the service life of the machine. Therefore, it is necessary to design a low-pressure gas supercharging device with a multi-pressurization structure. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a low-pressure gas boosting device with a multi-pressurization structure to solve the problems raised in the above-mentioned background technology. The present invention is provided with a multi-pressurization structure for boosting operation, which can perform both separate pressurization and combined pressurization.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a low-pressure gas boosting device with a multi-pressurization structure, comprising a casing, a driving motor is installed on the outer wall of the casing, the output shaft of the driving motor is fixedly connected to a linkage rod through a coupling, the outer wall of the linkage rod is fixedly connected to a semicircular driving plate, the outer wall of the semicircular driving plate is provided with a connecting shaft, the outer wall of the semicircular driving plate is installed with a driving rod through the connecting shaft, one end of the driving rod is fixedly connected to a boosting piston, an intake pipe is installed on the outer wall of the casing, one end of the intake pipe is fixedly connected to a mechanical worm gear, the outer wall of the mechanical worm gear is connected to an intake flange through the intake pipe, a micro-buffer assembly is installed on the outer wall of the casing, an adjusting assembly is installed on the outer wall of the casing, the outer wall of the adjusting assembly is fixedly connected to an exhaust pipe, and one end of the exhaust pipe is fixedly connected to an outlet flange.

[0006] Furthermore, the outer walls of the air inlet flange and the air outlet flange are both installed with mounting seats, and the outer walls of the mounting seats are connected to each other by mounting bolts.

[0007] Furthermore, the bottom of the casing is configured as a circular cavity, and the booster piston slides along the inner wall of the top cavity of the casing, and two groups of air hole channels are provided on the top of the casing.

[0008] Furthermore, the interior of the micro-buffer assembly includes a buffer bin, a buffer spring, a buffer piston and a push rod. The outer wall of the casing is fixedly connected to the buffer bin, the inner wall of the buffer bin is fixedly connected to the buffer spring, one end of the buffer spring is fixedly connected to the push rod, and the other end of the push rod is fixedly connected to the buffer piston.

[0009] Furthermore, a buffer channel is provided at the upper right corner of the housing, and the buffer piston slides along the buffer channel.

[0010] Furthermore, the interior of the adjustment component includes a sleeve, a movable threaded barrel, an inner shaft and an inner threaded barrel, the outer wall of the casing is fixedly connected to the inner shaft, the outer wall of the inner shaft is slidably mounted with a sleeve, the outer wall of the sleeve is fixedly connected to the movable threaded barrel, and the external thread of the movable threaded barrel is connected to the inner threaded barrel.

[0011] Furthermore, the other end of the internally threaded barrel is fixedly connected to the other end of the exhaust pipe, and the exhaust pipe can rotate by 360°.

[0012] The beneficial effects of the utility model are as follows: the utility model increases the pressure of the inhaled airflow by setting up multiple groups of pressurizing structures, so that the multiple groups of pressurizing structures can be separated for pressurizing operation or combined for operation, so that the gas pressure inside the boosting device can be increased, which is convenient for adding different pressures to different positions that need to be installed. The driving motor is used to drive the linkage rod to rotate, thereby driving the semicircular driving plate to rotate along the circular cavity at the bottom of the casing. During the rotation, the semicircular driving plate drives the driving rod to move up and down through the connecting shaft, thereby driving the boosting piston to push up and down, which is convenient for squeezing the pressurized gas into the outlet flange position, so that the exhaust gas pressure is enhanced. At the same time, when a higher atmospheric pressure is needed, the mechanical worm gear can be started to perform secondary pressurization. During the secondary pressurization process, the airflow with higher pressure can use the micro-buffer component to buffer the pressure, reduce the discharge pressure of the exhaust pipe, and thus improve the boosting effect of the boosting device.

[0013] The exhaust pipe position is installed by adjusting the component, and the outlet flange and the inlet flange are separated. The position of the outlet flange can be adjusted, that is, the shaft sleeve is rotated to drive the position of the movable threaded barrel to rotate, so that the internal threaded barrel and the movable threaded barrel can be installed and disassembled. After installation, since the shaft sleeve and the inner shaft are slidably installed, the installation position of the exhaust pipe can be adjusted when the outlet flange position is installed.

[0022] By utilizing the driving motor 2 to drive the linkage rod 3 to rotate, the semicircular driving plate 4 is driven to rotate along the circular cavity at the bottom of the casing 1. During the rotation, the semicircular driving plate 4 drives the driving rod 6 to move up and down through the connecting shaft 5, thereby driving the booster piston 7 to push up and down, so as to squeeze the pressurized gas into the position of the outlet flange 14, thereby enhancing the exhaust gas pressure. At the same time, when a higher atmospheric pressure is needed, the mechanical worm gear 9 can be started to perform secondary pressurization during the secondary pressurization process.

[0023] See also Figure 3 to Figure 4 The utility model provides a technical solution: the outer walls of the air inlet flange 10 and the air outlet flange 14 are both installed with a mounting seat 15, and the outer walls of the mounting seat 15 are connected to each other by mounting bolts.

[0024] The above structure connects the air inlet and outlet via the air inlet flange 10 and the air outlet flange 14 .

[0025] Preferably, the bottom of the casing 1 is configured as a circular cavity, and the booster piston 7 slides along the inner wall of the top cavity of the casing 1 , and two groups of air hole channels are provided on the top of the casing 1 .

[0026] The above structure reduces the gas space above by the booster piston 7, thereby achieving a pressurizing effect.

[0027] Preferably, the interior of the micro-buffer assembly 11 includes a buffer bin 1101, a buffer spring 1102, a buffer piston 1103 and a push rod 1104, the outer wall of the casing 1 is fixedly connected to the buffer bin 1101, the inner wall of the buffer bin 1101 is fixedly connected to the buffer spring 1102, one end of the buffer spring 1102 is fixedly connected to the push rod 1104, and the other end of the push rod 1104 is fixedly connected to the buffer piston 1103.

[0028] The above structure can buffer the pressure at the outlet position during the second pressurization process through the micro-buffer component 11 to prevent air leakage at the interface position.

[0029] Furthermore, a buffer channel is provided at the upper right corner of the housing 1, and the buffer piston 1103 slides along the buffer channel.

[0030] The above structure slides along the buffer channel through the buffer piston 1103.

[0031] Furthermore, the interior of the adjustment component 12 includes a sleeve 1201, a movable threaded barrel 1202, an inner shaft 1203 and an inner threaded barrel 1204. The outer wall of the casing 1 is fixedly connected to the inner shaft 1203, the outer wall of the inner shaft 1203 is slidably mounted with the sleeve 1201, the outer wall of the sleeve 1201 is fixedly connected to the movable threaded barrel 1202, and the external thread of the movable threaded barrel 1202 is connected to the inner threaded barrel 1204.

[0032] The above structure installs the position of the exhaust pipe 13 through the adjustment component 12, separates the outlet flange 14 and the inlet flange 10, and can adjust the position of the outlet flange 14.

[0033] Furthermore, the other end of the internal threaded tube 1204 is fixedly connected to the other end of the exhaust pipe 13, and the exhaust pipe 13 can rotate at an angle of 360°.

[0034] The above structure can adjust the installation position of the exhaust pipe 13 by installing the position of the outlet flange 14 .

[0035] Specific implementation method: First, by setting up multiple groups of pressurizing structures, the pressure of the inhaled airflow is increased, so that the multiple groups of pressurizing structures can increase the gas pressure inside the boosting device, which is convenient for adding different pressures to different installation positions. The driving motor 2 is used to drive the linkage rod 3 to rotate, thereby driving the semicircular driving plate 4 to rotate along the circular cavity at the bottom of the casing 1. During the rotation process, the semicircular driving plate 4 drives the driving rod 6 to move up and down through the connecting shaft 5, thereby driving the boosting piston 7 to push up and down, which is convenient for squeezing the pressurized gas into the position of the outlet flange 14, so that the exhaust gas pressure is enhanced; secondly, when a higher atmospheric pressure is needed, the mechanical worm gear 9 can be started to convert high-speed and low-pressure air into low-speed and high-pressure air. When air molecules hit these blades, they will slow down, thereby reducing Low air flow velocity and increased pressure allow for secondary pressurization. During the secondary pressurization process, the micro-buffer component 11 can be used to buffer the pressure of the air flow with a relatively high pressure, thereby reducing the discharge pressure of the exhaust pipe 13 and improving the supercharging effect of the supercharging device. Finally, the adjusting component 12 installs the position of the exhaust pipe 13 and separates the outlet flange 14 from the inlet flange 10. The position of the outlet flange 14 can be adjusted, that is, the sleeve 1201 is rotated to drive the position of the movable threaded barrel 1202 to rotate, thereby installing and disassembling the internal threaded barrel 1204 and the movable threaded barrel 1202. After installation, since the sleeve 1201 and the inner shaft 1203 are slidably installed, the installation position of the exhaust pipe 13 can be adjusted when the position of the outlet flange 14 is installed.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
