Description

Technical Field

[0001] This utility model relates to the field of engine technology, and more specifically, to a gas mixer, and more particularly to a gas mixer and a gas engine. Background Technology

[0002] The gas mixer is a crucial component of a gas engine. Its function is to ensure that the gas engine receives a proper, proportional, and uniform mixture of air and fuel to achieve a highly efficient and clean combustion process. This improves the performance and economy of the gas engine while reducing pollutant emissions. During gas usage, the gas mixer plays a vital role, and its performance directly affects the combustion efficiency, safety, and lifespan of the equipment.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following defects often exist: when gas is mixed in the mixer, its own flow characteristics and complex fluid dynamics easily induce vibration. Furthermore, when installed on mobile equipment or affected by vibrations transmitted from surrounding operating machinery, the mixer is in a state of constant vibration, causing continuous impact on the connecting pipes. Moreover, some existing mixers have poor filtration mechanisms, leading to the long-term accumulation of impurities, which not only wears down the inner wall of the pipes but also affects the gas mixing effect. Therefore, to address the above problems, a gas mixer and a gas engine are proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the vibration easily caused by the flow characteristics and complex fluid dynamics of gas mixing within the mixer, which, when installed on mobile equipment or affected by vibrations transmitted from surrounding operating machinery, results in the mixer being in a state of constant vibration, causing continuous impact on connecting pipes. Furthermore, some existing mixers have inadequate filtration mechanisms, leading to the long-term accumulation of impurities that both wear down the inner walls of the pipes and affect the gas mixing effect. Therefore, this invention proposes a gas mixer and gas engine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gas mixer, comprising a mixer body, a first flange fixedly connected to one end of the mixer body, a second flange fixedly connected to the other end of the mixer body, a connecting pipe internally connected to the mixer body, a plurality of U-shaped frames fixedly connected to the arc surface of the mixer body, a buffer block slidably connected to the inner wall of the U-shaped frame, a threaded groove provided on one side of the buffer block, a threaded rod threadedly inserted into the U-shaped frame, the threaded rod being threadedly connected to the inner wall of the threaded groove of the buffer block, a circular chamber fixedly connected to the surface of the buffer block, a first spring fixedly connected to the inner wall of the circular chamber, a sliding rod fixedly connected to the end of the first spring away from the U-shaped frame, the sliding rod being slidably connected to the inner wall of the circular chamber, and a mounting plate fixedly connected to the end of the sliding rod away from the U-shaped frame, the surface of the mounting plate having a plurality of mounting holes.

[0006] The effect achieved by the above components is as follows: the slide rod is connected to the first spring inside the cylindrical chamber. When the mixer vibrates during operation, the slide rod can slide inside the cylindrical chamber. The first spring plays a buffering and shock absorption role. It can buffer and reduce vibration during the mixing process of the mixer body, reduce the loosening and wear of components caused by vibration, and reduce the interference of external vibration on the gas mixing process inside the mixer, thereby improving the stability and reliability of the mixer body during operation.

[0007] Preferably, a buffer pad is fixedly connected to the upper surface of the buffer block, and the buffer pad is made of rubber.

[0008] The effects achieved by the above components are as follows: the buffer pad is made of rubber and fixed to the upper surface of the buffer block. By utilizing the good elasticity and shock absorption properties of rubber, the buffering effect can be further enhanced, the vibration energy can be absorbed, the vibration transmission during the operation of the mixer body can be reduced, and it can also play a certain role in wear resistance and protection.

[0009] Preferably, one end of the threaded rod is fixedly connected to a round shaft, and the round shaft has a plurality of anti-slip grooves on its arc surface.

[0010] The aforementioned components achieve the following effects: the round shaft at one end of the threaded rod makes it easier for the operator to adjust the threaded rod; its anti-slip groove increases the friction between the hand and the round shaft, making it easier and more stable to rotate the threaded rod, thus improving operational convenience. Preferably, a mounting bracket is fixedly connected to the inner wall of the second flange, and a filter screen is slidably connected to the inner wall of the mounting bracket.

[0011] The effects achieved by the above components are as follows: the filter screen can filter the gas entering the mixer, effectively intercept impurity particles in the gas, prevent them from entering the interior of the mixer, avoid impurities from causing wear on the internal structure or connecting pipes of the mixer, thereby ensuring the smooth operation of the mixer, extending the service life of the mixer, and ensuring the purity of the mixed gas.

[0012] Preferably, one end of the mounting bracket is fixedly connected to two fixing blocks, a fixing rod is slidably inserted into the fixing block, and a round block is fixedly connected to one end of the fixing rod.

[0013] The above components achieve the following effect: regular replacement of the filter screen ensures that the filter screen maintains good filtration performance, effectively intercepts impurities in the gas, avoids long-term accumulation of impurities that could clog the filter screen, and ensures smooth gas flow.

[0014] Preferably, a second spring is fitted onto the arc surface of the fixing rod, and the two ends of the second spring are fixedly connected to the fixing block and the circular block, respectively.

[0015] The effect achieved by the above components is as follows: after installing a new filter screen on the inner wall of the mounting bracket, releasing the round block will cause the elastic force of the second spring to push the round block so that the fixing rod automatically moves forward to lock the filter screen, achieving quick installation and making the operation more convenient.

[0016] Preferably, one end of the filter screen is fixedly connected to a connecting shaft.

[0017] The effect achieved by the above components is that workers can more easily and accurately pull the filter screen by holding the connecting shaft, allowing it to slide within the mounting bracket, which further facilitates the disassembly and replacement of the filter screen.

[0018] In summary, the beneficial effects of this utility model are as follows: In this invention, a first spring inside the cylindrical chamber is connected to a sliding rod. When the mixer vibrates during operation, the sliding rod can slide inside the cylindrical chamber. The first spring acts as a buffer and shock absorber, which can buffer and reduce vibration during the mixing process of the mixer body, reduce the loosening and wear of parts caused by vibration, and reduce the interference of external vibration on the gas mixing process inside the mixer, thereby improving the stability and reliability of the mixer body during operation.

[0021] Reference Figures 1-6As shown, this utility model provides a technical solution: a gas mixer, including a mixer body 1, a first flange 2 fixedly connected to one end of the mixer body 1, a second flange 3 fixedly connected to the other end of the mixer body 1, a connecting pipe 14 connected internally to the mixer body 1, a plurality of U-shaped frames 4 fixedly connected to the arc surface of the mixer body 1, a buffer block 5 slidably connected to the inner wall of the U-shaped frame 4, a threaded groove opened on one side of the buffer block 5, a threaded rod 6 threadedly inserted into the U-shaped frame 4, the threaded rod 6 being threadedly connected to the inner wall of the threaded groove of the buffer block 5, a circular chamber 7 fixedly connected to the surface of the buffer block 5, a first spring 8 fixedly connected to the inner wall of the circular chamber 7, a sliding rod 9 fixedly connected to the end of the first spring 8 away from the U-shaped frame 4, the sliding rod 9 being threadedly connected to the inner wall of the circular chamber 7. The wall is slidably connected, and the end of the slide rod 9 away from the U-shaped frame 4 is fixedly connected to the mounting plate 10. The surface of the mounting plate 10 has several mounting holes 11. It is connected to the slide rod 9 through the first spring 8 inside the cylindrical chamber 7. When the mixer vibrates during operation, the slide rod 9 can slide inside the cylindrical chamber 7. The first spring 8 plays a buffering and shock-absorbing role. It can buffer and reduce vibration during the mixing process of the mixer body 1, reduce the loosening and wear of parts caused by vibration, and reduce the interference of external vibration on the internal gas mixing process of the mixer, thereby improving the stability and reliability of the mixer body 1 during operation. The upper surface of the buffer block 5 is fixedly connected to the buffer pad 13. The buffer pad 13 is made of rubber and is fixed to the upper surface of the buffer block 5. The good elasticity and shock absorption properties of the rubber can further enhance the buffering effect, absorb vibration energy, and reduce the vibration transmission of the mixer body 1 during operation. It also provides a certain degree of wear resistance and protection. A round shaft 12 is fixedly connected to one end of the threaded rod 6. Several anti-slip grooves are formed on the arc surface of the round shaft 12. The round shaft 12 at one end of the threaded rod 6 makes it easier for the operator to adjust the threaded rod 6. The anti-slip grooves increase the friction between the hand and the round shaft 12, making it easier and more stable to rotate the threaded rod 6, thus improving operational convenience. A mounting bracket 15 is fixedly connected to the inner wall of the second flange 3. A filter screen 16 is slidably connected to the inner wall of the mounting bracket 15. The filter screen 16 filters the gas entering the mixer, effectively intercepting impurities in the gas and preventing... The filter screen 16 is inserted into the mixer to prevent impurities from causing wear to the internal structure or connecting pipe 14, thus ensuring smooth operation and extending its service life. It also ensures the purity of the mixed gas. Two fixing blocks 17 are fixedly connected to one end of the mounting bracket 15. A fixing rod 18 is slidably inserted into the fixing block 17, and a round block 19 is fixedly connected to one end of the fixing rod 18. This allows for the periodic replacement of the filter screen 16. Regular replacement of the filter screen 16 maintains its good filtration performance, effectively intercepting impurities in the gas and preventing long-term accumulation that could clog the filter, ensuring smooth gas flow. A second spring 20 is fitted onto the arc surface of the fixing rod 18, with both ends of the second spring 20 fixedly connected to the fixing block 17 and the round block 19, respectively.After installing the new filter screen 16 on the inner wall of the mounting bracket 15, release the round block 19. The elastic force of the second spring 20 will push the round block 19, causing the fixing rod 18 to automatically move forward and lock the filter screen 16, achieving quick installation and making operation more convenient. One end of the filter screen 16 is fixedly connected to the connecting shaft 21. By holding the connecting shaft 21, the operator can more easily and accurately pull the filter screen 16, allowing it to slide within the mounting bracket 15, further facilitating the removal and replacement of the filter screen 16.

[0022] The working principle is as follows: First, the mounting plate 10 is fixed to the equipment or the location where it needs to be placed through the mounting holes 11. Then, rotating the circular shaft 12 drives the threaded rod 6 to fix the buffer block 5. During the mixing operation of the mixer body 1, the mixer body 1 will generate a certain vibration due to its own operation or external factors. At this time, the slide rod 9 will slide on the inner wall of the circular chamber 7 on the buffer block 5 under the elastic action of the first spring 8. Together with the rubber buffer pad 13 on the buffer block 5, it will absorb some of the vibration energy, thereby reducing the impact of vibration on the internal structure of the mixer body 1 and improving the operational stability. When the gas passes through the filter screen 16, particulate impurities in the gas are intercepted, ensuring that the internal structure of the mixer is not worn. When the filter screen 16 needs to be removed, the fixed rod 18 is moved backward by pulling the round block 19, and then the filter screen 16 is pulled out by holding the connecting shaft 21, so as to achieve convenient removal of the filter screen 16. When a new filter screen 16 needs to be installed, the fixed rod 18 is moved backward by pulling the round block 19, and the filter screen 16 is pulled to the inner wall of the mounting bracket 15 by holding the connecting shaft 21. After releasing the round block 19, the elastic force of its second spring 20 will drive the fixed rod 18 forward to lock the filter screen 16 to maintain good filtration performance, and ultimately ensure the efficient and stable operation of the gas mixer.
