Description

Technical Field

[0001] This utility model relates to the fields of biomass gasification furnaces and tar, and particularly to biomass gasification furnaces and tar sampling devices. Background Technology

[0002] A biomass gasifier tar sampling device is used to collect and analyze tar samples generated during the biomass gasification process. Its main function is to help researchers and technicians understand tar production during biomass gasification, thereby optimizing the gasifier's design and operating parameters, improving gasification efficiency and fuel quality. The biomass gasifier tar sampling device is an indispensable part of biomass gasification technology and is of great significance for promoting the efficient utilization of biomass energy.

[0003] In existing technologies, biomass gasifiers and tar sampling devices introduce sampling gas into the device through an inlet. Under pressure, the gas passes sequentially through sampling bottles containing organic solutions, where the tar is diluted, cooled, and collected. However, when the sampling bottles are fixed to extract the tar, it becomes impossible to directly extract the sampled tar. Tools are needed to extract the tar from the bottles, reducing sampling efficiency. This also makes extracting the diluted and cooled tar from the bottles inconvenient, affecting sampling efficiency, reducing sampling accuracy, and decreasing the practicality of the sampling device. Therefore, improvements to biomass gasifiers and tar sampling devices are needed to solve these problems. Utility Model Content

[0004] To overcome the problem that the sampling bottle is fixed inside the sampling device, making it impossible to directly extract the sampled tar, a tool is needed to extract the tar from inside the sampling bottle, thus reducing the sampling efficiency.

[0005] The technical solution of this utility model is as follows: a biomass gasification furnace and a tar sampling device, including a sampling bottle and a sampling box body, and further including a fixed semicircular block, a threaded rod, a slider, a movable semicircular block and a fixing component. The sampling bottle is slidably connected inside the sampling box body, and a fixing component is set on the outside of the sampling box body. The threaded rod is rotatably connected inside the sampling box body, and the slider is threadedly connected to the outside of the threaded rod. The slider slides inside the sampling box body, and the movable semicircular block is fixedly connected to the bottom of the slider. The fixed semicircular block is fixedly connected to the bottom of the sampling box body. By rotating the threaded rod, the movable semicircular block is moved to the fixed semicircular block through the slider.

[0006] Preferably, by pressing the semi-circular movable shaft, then pulling the leg bracket upwards, and then resetting it via the first spring, the telescopic leg bracket is limited, raising the height of the sampling box body. This facilitates the removal of the sampling bottle from the sampling box body. Rotating the threaded rod inside the sampling box body causes the slider to move via the threaded connection, engaging with the fixed semi-circular block at the bottom of the sampling box body. This secures the sampling bottle, preventing it from moving. Furthermore, the groove on the movable semi-circular block relative to the sampling bottle prevents the bottle from falling due to gravity when secured. This allows the sampling bottle to be secured or removed, facilitating the retrieval of the tar sample inside the bottle and improving the biomass... The efficiency of gasification furnace and tar sampling improves the practicality of the device. A sealing strip prevents pressure leakage from the sampling bottle when the suction pump extracts the sampling gas from the sampling tube, thus avoiding insufficient pressure inside the sampling tube. Pushing the second handle outward causes the sliding shaft to slide within the corresponding groove of the limiting block, moving the limiting rod away from the corresponding groove of the sampling box cover. This allows the sampling box cover to be rotated inside the sampling box body using the first handle. The second spring's reset mechanism brings the limiting rod into contact with the corresponding groove of the sampling box cover, securing the cover. This facilitates observation of the biomass gasification furnace and tar sampling process, improving sampling efficiency, allowing for monitoring of the sampling process, preventing accidents during sampling, and enhancing practicality.

[0007] Preferably, the sampling box body has a groove at the corresponding position of the slider, the slider slides in the groove, and the movable semicircular block has a groove at the corresponding position of the sampling bottle, the sampling bottle is in contact with the groove, and the groove allows the sampling bottle to be fixed, moved and disassembled, thereby improving the extraction effect of tar samples inside the sampling bottle and improving the practicality of the device.

[0008] Preferably, the bottom of the sampling bottle is fixedly connected to a leg frame, the outside of which is slidably connected to a telescopic foot frame. A semi-circular movable shaft is slidably connected inside the leg frame and the telescopic foot frame. A first spring is fixedly connected between the semi-circular movable shaft and a first spring. A sampling inlet is fixedly connected inside the sampling box. A sampling tube is fixedly connected to the left side of the sampling inlet. A fixing frame is fixedly connected inside the sampling bottle. The sampling tube is fixedly connected inside the fixing frame. A sampling outlet is provided inside the sampling tube. A suction pump is fixedly connected to the left side of the sampling tube. The suction pump is fixedly connected to the left side of the sampling box. A sealing strip is fixedly connected inside the sampling bottle. By rotating the threaded rod, the movable semi-circular block is moved towards the fixed semi-circular block via a slider, thereby fixing or removing the sampling bottle. This facilitates the removal of tar samples from the sampling bottle, improving the efficiency of biomass gasification furnace and tar sampling, and enhancing the practicality of the device.

[0009] Preferably, six sealing strips are provided, and the six sealing strips are in contact with the sampling tube. The sealing strips prevent the pressure inside the sampling bottle from leaking when the suction pump draws the sampling gas from inside the sampling tube, thus preventing insufficient pressure inside the sampling tube.

[0010] Preferably, the telescopic tripod has a groove at the corresponding position of the leg frame, and the leg frame slides in the groove. The leg frame also has a groove at the corresponding position of the semi-circular movable shaft, and the semi-circular movable shaft slides in the groove. The groove allows the leg frame to slide out of the telescopic tripod. The first spring resets the leg frame, and the semi-circular movable shaft is limited to prevent the leg frame from moving. This makes it easier to remove the sampling bottle from the inside of the sampling box (4) and improves its practicality.

[0011] Preferably, the fixing component includes a sampling box cover, which is rotatably connected to the inside of the sampling box body. A first handle is fixedly connected to the top of the sampling box cover. A limit block is fixedly connected inside the sampling box body. A sliding shaft is slidably connected inside the limit block. A U-shaped plate is fixedly connected to the front end of the sliding shaft. A second handle is fixedly connected to the front end of the U-shaped plate. A second spring is fixedly connected between the sliding shaft and the limit block. A limit rod is fixedly connected inside the U-shaped plate. By pulling the second handle outward, the sliding shaft is driven to slide in the corresponding groove of the limit block, moving the limit rod away from the corresponding groove of the sampling box cover. This allows the sampling box cover to be rotated inside the sampling box body via the first handle, facilitating observation of the biomass gasification furnace and tar sampling process, improving sampling efficiency, allowing the sampling process to be observed, preventing accidents during sampling, and enhancing practicality.

[0012] Preferably, the limiting block has a groove at the corresponding position of the sliding shaft, and the sliding shaft slides in the groove. The sampling box cover has a groove at the corresponding position of the limiting rod, and the limiting rod contacts the groove. The groove limits the sliding shaft and prevents it from sliding out. The groove on the sampling box cover at the corresponding position of the limiting rod allows it to contact the limiting rod, thereby fixing the sampling bottle and preventing it from rotating. This allows the state of the sampling box cover to be adjusted. It can be opened when it is necessary to observe the sampling process, and conversely, the sampling box cover can be fixed to prevent it from sliding.

[0013] The beneficial effects of this utility model are as follows: Compared to fixing the sampling bottle inside the sampling device, by rotating the threaded rod, the movable semicircular block is moved to the fixed semicircular block via the slider. This allows the movable semicircular block to engage with the fixed semicircular block at the bottom of the sampling box, thus fixing the sampling bottle and preventing it from moving. Furthermore, the grooves opened at the corresponding positions of the movable semicircular block relative to the sampling bottle prevent the sampling bottle from falling downwards when it is fixed, making it easier to retrieve the tar sample inside the sampling bottle. This improves the efficiency of biomass gasification furnace and tar sampling, enhances the practicality of the device, and avoids the problem that fixing the sampling bottle inside the sampling device would prevent the direct extraction of the sampled tar, requiring tools to extract the tar from the sampling bottle, thereby reducing sampling efficiency.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1-Figure 5This utility model provides an embodiment of a biomass gasification furnace and a tar sampling device, including a sampling bottle 1, a sampling box body 4, and further including a fixed semicircular block 25, a threaded rod 26, a slider 27, a movable semicircular block 28, and a fixing assembly. The sampling bottle 1 is slidably connected inside the sampling box body 4, and the fixing assembly is provided on the outside of the sampling box body 4. The threaded rod 26 is rotatably connected inside the sampling box body 4, and the slider 27 is threadedly connected to the outside of the threaded rod 26. The slider 27 slides inside the sampling box body 4, and the bottom of the slider 27 is fixed. A movable semicircular block 28 is connected to the bottom of the sampling box body 4, and a fixed semicircular block 25 is fixedly connected to it. By rotating the threaded rod 26, the movable semicircular block 28 is moved to the fixed semicircular block 25 via the slider 27. The sampling box body 4 has a groove at the corresponding position of the slider 27, and the slider 27 slides in the groove. The movable semicircular block 28 has a groove at the corresponding position of the sampling bottle 1, and the sampling bottle 1 is in contact with the groove. The groove allows the sampling bottle 1 to be fixed, moved, and disassembled, thereby improving the extraction effect of tar samples inside the sampling bottle 1 and improving the practicality of the device.

[0022] Please see Figures 2-5In this embodiment, a leg frame 21 is fixedly connected to the bottom of the sampling bottle 1. A telescopic foot frame 22 is slidably connected to the outside of the leg frame 21. A semi-circular movable shaft 23 is slidably connected inside the leg frame 21 and the telescopic foot frame 22. A first spring 24 is fixedly connected between the semi-circular movable shaft 23 and the first spring 24. A sampling inlet 29 is fixedly connected inside the sampling box body 4. A sampling tube 210 is fixedly connected to the left side of the sampling inlet 29. A fixing frame 211 is fixedly connected inside the sampling bottle 1. The sampling tube 210 is fixedly connected inside the fixing frame 211. A sampling outlet 212 is provided inside the sampling tube 210. A suction pump 213 is fixedly connected to the left side of the sampling tube 210. The suction pump 213 is fixedly connected to the left side of the sampling box body 4. A sealing strip 214 is fixedly connected inside the sampling bottle 1. By rotating the threaded rod 26, it moves the movable semi-circular block 28 towards the fixed semi-circular block 25 via the slider 27, thereby moving the sampling bottle 1... The device can be fixed or removed, facilitating the retrieval of tar samples from the sampling bottle 1, thereby improving the efficiency of biomass gasification and tar sampling and enhancing the practicality of the device. Six sealing strips 214 are provided, each contacting the sampling tube 210. These sealing strips prevent pressure leakage inside the sampling bottle 1 when the suction pump 213 extracts the sampling gas from the sampling tube 210, thus preventing insufficient pressure inside the sampling tube 210. The telescopic legs 22 have grooves at corresponding positions on the legs 21, allowing the legs 21 to slide within these grooves. The legs 21 also have grooves at corresponding positions on the semi-circular movable shaft 23, allowing the semi-circular movable shaft 23 to slide within these grooves. These grooves allow the legs 21 to slide out of the telescopic legs 22 and be reset by the first spring 24, which then limits the semi-circular movable shaft 23 to prevent movement of the legs 21, facilitating the removal of the sampling bottle 1 from the sampling box 4 and improving practicality.

[0023] Please see Figure 1 , Figure 5In this embodiment, the fixing component includes a sampling box cover 31, which is rotatably connected to the inside of the sampling box body 4. A first handle 32 is fixedly connected to the top of the sampling box cover 31. A limit block 33 is fixedly connected inside the sampling box body 4. A sliding shaft 34 is slidably connected inside the limit block 33. A U-shaped plate 35 is fixedly connected to the front end of the sliding shaft 34. A second handle 36 is fixedly connected to the front end of the U-shaped plate 35. A second spring 37 is fixedly connected between the sliding shaft 34 and the limit block 33. A limit rod 38 is fixedly connected inside the U-shaped plate 35. By pushing the second handle 36 outward, the sliding shaft 34 is driven to slide in the corresponding groove of the limit block 33, moving the limit rod 38 away from the corresponding groove of the sampling box cover 31. This allows the sampling box cover 31 to be moved by the first handle 32. The sampling box 4 rotates internally to facilitate observation of the sampling process of the biomass gasifier and tar, improving sampling efficiency, allowing for monitoring of the sampling process, preventing accidents during sampling, and enhancing practicality. A limiting block 33 has a groove at a corresponding position on the sliding shaft 34, allowing the sliding shaft 34 to slide within the groove. A corresponding groove on the sampling box cover 31 is provided on a limiting rod 38, with the limiting rod 38 contacting the groove. The groove limits the sliding shaft 34, preventing it from sliding out. The groove on the sampling box cover 31, along with the corresponding position on the limiting rod 38, allows the limiting rod 38 to contact the limiting rod, thus fixing the sampling bottle 1 and preventing it from rotating. The state of the sampling box cover 31 can be adjusted; it can be opened when the sampling process needs to be observed, and closed otherwise to prevent sliding.

[0024] During operation, pressing the semi-circular movable shaft 23 and pulling the leg bracket 21 upwards, followed by the first spring 24 resetting it, limits the telescopic leg bracket 22, raising the height of the sampling box body 4 to facilitate the removal of the sampling bottle 1 from inside the sampling box body 4. Rotating the threaded rod 26 inside the sampling box body 4 causes the slider 27 to move, engaging with the fixed semi-circular block 28 at the bottom of the sampling box body 4 to secure the sampling bottle 1 and prevent movement. The groove on the movable semi-circular block 28 relative to the sampling bottle 1 prevents the bottle 1 from falling due to gravity when secured, thus allowing for easy fixation and removal of the sampling bottle 1, facilitating the retrieval of the tar sample inside. This improves the efficiency of the biomass gasification furnace. The efficiency of tar sampling is improved, enhancing the practicality of the device. A sealing strip 214 prevents pressure leakage inside the sampling bottle 1 when the suction pump 213 extracts the sampling gas from the sampling tube 210, thus avoiding insufficient pressure inside the sampling tube 210. Pushing the second handle 36 outward causes the sliding shaft 34 to slide within the corresponding groove of the limiting block 33, moving the limiting rod 38 away from the corresponding groove of the sampling box cover 31. This allows the sampling box cover 31 to rotate inside the sampling box body 4 via the first handle 32. The second spring 37 then resets the limiting rod 38, ensuring contact with the corresponding groove of the sampling box cover 31, thereby fixing the cover. This facilitates observation of the biomass gasification furnace and tar sampling process, improving sampling efficiency, allowing for monitoring of the sampling process, preventing accidents during sampling, and enhancing practicality.

[0025] Through the above steps, by rotating the threaded rod 26, it drives the movable semicircular block 28 to move towards the fixed semicircular block 25 via the slider 27. This solves the problem that the sampling bottle 1 is fixed inside the sampling device, which makes it impossible to directly extract the sampled tar. Instead, a tool is needed to extract the tar inside the sampling bottle 1, thus reducing the sampling efficiency.
