Description

Technical Field

[0001] This utility model belongs to the field of furnace gas detection equipment, specifically relating to a furnace gas detection sampling gun. Background Technology

[0002] Boilers in chemical plants, steel mills, and pharmaceutical factories emit large amounts of waste gas during operation. This waste gas not only has a strong odor but also contains a large number of toxic and harmful gases, severely polluting the environment and affecting human health. Therefore, it is necessary to use gas sampling guns to regularly sample the boiler waste gas. In traditional sampling operations, sampling bottles are individually mounted on the sampling gun, requiring frequent bottle replacements. While some existing sampling guns can accommodate multiple sampling bottles, their complex structure, low sampling efficiency, and inconvenient use make them problematic. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model aims to provide a furnace gas detection sampling gun. This device can effectively adjust the detection position of the sampling gun, has high sampling efficiency, and can install multiple sampling bottles, avoiding the problem of frequent gas bottle replacements, making it very convenient to use.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A furnace gas detection sampling gun includes an extraction pipe and an air pump. The extraction pipe is horizontally slidably mounted on a lifting platform of a lifting mechanism, and an extraction hood is installed at the head of the extraction pipe. A transverse drive mechanism is installed on the lifting platform, and the actuating part of the transverse drive mechanism is connected to the extraction pipe. A vertical frame is fixedly mounted on the lifting platform, and a sleeve is vertically mounted on the frame. Multiple air holes are evenly spaced along the axial direction on the side wall of the sleeve, and an airtight valve is installed at each air hole. The airtight valve is detachably connected to a sampling bottle. A piston block is movably mounted inside the sleeve, and an air passage is provided inside the piston block. An air inlet is installed at the air inlet below the air passage, and the air outlet of the air passage is located on the side of the piston block and is opposite to the air holes. A displacement adjustment mechanism for driving the piston block is installed on the frame. The air pump is mounted on the lifting platform. The air inlet of the air pump is connected to the tail end of the extraction pipe through a first flexible pipe, and the air outlet of the air pump is connected to the air inlet through a second flexible pipe.

[0006] Furthermore, the lifting mechanism also includes a first telescopic cylinder, which is vertically mounted on the base, and the piston rod of the first telescopic cylinder is fixedly connected to the bottom of the lifting platform.

[0007] Furthermore, the lateral movement drive mechanism includes a second telescopic cylinder, which is horizontally mounted on the lifting platform, and the piston rod of the second telescopic cylinder is fixedly connected to the air extraction pipe.

[0008] Furthermore, the lifting platform is provided with a sliding groove parallel to the air extraction pipe, and a slider is slidably engaged in the sliding groove. The tail end of the air extraction pipe and the piston rod of the second telescopic cylinder are both fixed on the slider.

[0009] Furthermore, the end of the lifting platform is provided with a fixing block, and a sliding hole is horizontally opened through the fixing block, through which the air extraction pipe is movably inserted.

[0010] Furthermore, the displacement adjustment mechanism includes a screw, a motor, and a gear ring. The gear ring is coaxially rotatably mounted at the upper opening of the sleeve. The screw is coaxially disposed inside the sleeve and threadedly sleeved inside the gear ring. The motor is vertically mounted on the stand, and a gear is coaxially fixed to the output shaft of the motor. The gear meshes with the external teeth on the outer circumference of the gear ring. The lower end of the screw is fixed to the piston block.

[0011] Furthermore, both the upper and lower ends of the piston block are fitted with sealing rings that abut against the inner wall of the sleeve.

[0012] Furthermore, the sampling bottle is mounted on the stand by means of a clamp.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The extraction pipe and other structures of this application are all installed on the lifting platform. The extension and retraction of the first telescopic cylinder can drive the various components on the lifting platform to move up and down, thereby adjusting the sampling height of the sampling gun.

[0015] 2. When the second telescopic cylinder of this application drives the suction pipe to extend horizontally, the sliding cooperation between the slider and the slide groove can improve the stability of the suction pipe during horizontal movement. Furthermore, the suction pipe is slidably sleeved in the fixed block at the end of the lifting platform, so that the fixed block can effectively guide the head of the suction pipe during its extension and retraction, thereby improving the stability of the suction pipe during its extension and retraction.

[0016] 3. When the motor controls the operation of this application, the rotational engagement of the gear and the gear ring drives the screw threaded inside the gear ring to move up and down, thereby causing the piston block to move up and down within the sleeve to adjust its position. When the air outlet on the piston block is aligned with the air hole on the sleeve, under the action of the air pump, the furnace gas at the end of the extraction pipe can be sent to the sampling bottle through the air passage, air hole, and airtight valve, thereby realizing the rapid adjustment of the piston block position and the gas collection operation of different sampling bottles, significantly improving the furnace gas sampling efficiency of this device.

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.

[0020] like Figure 1-2 As shown, this utility model proposes a furnace gas detection sampling gun, including a lifting mechanism, an extraction pipe 3, and an air pump 5. The lifting mechanism includes a lifting platform 2 and a first telescopic cylinder 11. The first telescopic cylinder 11 is vertically mounted on the base 1, and the piston rod of the first telescopic cylinder 11 is fixed to the bottom of the lifting platform 2. The first telescopic cylinder 11 adopts a hydraulic cylinder structure.

[0021] The extraction pipe 3 and other structures in this application are all installed on the lifting platform 2. The extension and retraction of the first telescopic cylinder 11 can drive the various components on the lifting platform 2 to perform lifting and retraction actions, thereby adjusting the sampling height of the sampling gun.

[0022] The suction pipe 3 is horizontally slidably mounted on the lifting platform 2 of the lifting mechanism, and a suction hood 31 is installed at the head of the suction pipe 3. A transverse drive mechanism is installed on the lifting platform 2, and the actuating part of the transverse drive mechanism is connected to the suction pipe 3. The transverse drive mechanism includes a second telescopic cylinder 4, which is horizontally mounted on the lifting platform 2, and the piston rod of the second telescopic cylinder 4 is fixedly connected to the suction pipe 3. A sliding groove 20 parallel to the suction pipe 3 is provided on the lifting platform 2, and a slider 22 is slidably engaged in the sliding groove 20. The tail end of the suction pipe 3 and the piston rod of the second telescopic cylinder 4 are both fixed to the slider 22. A fixing block 21 is provided at the end of the lifting platform 2, and a sliding hole is horizontally opened through the fixing block 21, through which the suction pipe 3 is movably inserted. The second telescopic cylinder 4 can be a cylinder structure.

[0023] When the second telescopic cylinder 4 of this application drives the suction pipe 3 to extend horizontally, the sliding cooperation between the slider 22 and the slide groove 20 can improve the stability of the suction pipe 3 during horizontal movement. Furthermore, the suction pipe 3 is slidably sleeved in the fixing block 21 at the end of the lifting platform 2, so that the fixing block 21 can effectively guide the head of the suction pipe 3 during its extension and retraction, thereby improving the stability of the suction pipe 3 during its extension and retraction.

[0024] A vertical support frame 23 is fixedly mounted on the lifting platform 2. A sleeve 6 is vertically installed on the support frame 23. Multiple air holes 60 are evenly spaced along the axial direction on the side wall of the sleeve 6. An airtight valve 81 is installed at each air hole 60, and the airtight valve 81 is detachably connected to the sampling bottle 8. The sampling bottle 8 and the port of the airtight valve 81 can be connected by a flange or a quick-release connector, as is used in existing technology. The airtight valve 81 can be a manually controlled valve or an electrically controlled airtight valve. When a manually controlled valve is used, the sleeve 6 can be designed to be transparent, making it easier to observe the position of the piston block 62. In addition, to improve the ease of installation, the sampling bottle 8 is mounted on the support frame 23 by a clamp 231. The clamp 231 structure makes the installation and removal of the sampling bottle 8 more convenient.

[0025] Air pump 5 is installed on lifting platform 2. The air inlet of air pump 5 is connected to the tail end of suction pipe 3 through first flexible pipe 51, and the air outlet of air pump 5 is connected to air inlet 622 through second flexible pipe 52. Both flexible pipes can be corrugated connecting pipes or other deformable flexible connecting pipes in the prior art. While ensuring gas communication, they can also deform or expand without affecting the operation of suction pipe 3, piston block 62 and other structures.

[0026] A piston block 62 is movably mounted inside the sleeve 6. An air passage 620 is provided within the piston block 62. An air inlet 622 is installed at the air inlet below the air passage 620. The air outlet of the air passage 620 is located on the side of the piston block 62 and is opposite to the air hole 60. A displacement adjustment mechanism for driving the piston block 62 is mounted on the support frame 23. The displacement adjustment mechanism includes a screw 61, a motor 71, and a gear ring 73. The gear ring 73 is coaxially rotatably mounted at the upper opening of the sleeve 6. The screw 61 is coaxially located inside the sleeve 6 and threadedly fitted inside the gear ring 73. The motor 71 is vertically mounted on the support frame 23. A gear 72 is coaxially fixed to the output shaft of the motor 71, and the gear 72 meshes with the external teeth on the outer circumference of the gear ring 73. The lower end of the screw 61 is fixed to the piston block 62.

[0027] When the control motor 71 operates, the rotational engagement of the gear 72 and the gear ring 73 drives the screw 61, which is threaded inside the gear ring 73, to move up and down. This, in turn, moves the piston block 62 up and down within the sleeve 6 to adjust its position. When the air outlet on the piston block 62 aligns with the air hole 60 on the sleeve 6, the furnace gas at the end of the suction pipe 3 can be delivered to the sampling bottle 8 through the air passage 620, the air hole 60, and the airtight valve 81 under the action of the air pump 5. This enables rapid adjustment of the piston block 62's position and gas collection from different sampling bottles 8, significantly improving the furnace gas sampling efficiency of this device. A vertical hole (not shown in the figure) can be vertically drilled through the gear ring 73 to balance the air pressure at the upper end of the sleeve 6 when the piston block 62 moves.

[0028] Both the upper and lower ends of the piston block 62 are fitted with sealing rings 621 that abut against the inner wall of the sleeve 6. The sealing rings 621 at the upper and lower ends of the piston block 62 can significantly improve the airtightness of the connection between the piston block 62 and the sleeve 6, thereby improving the structural stability of the device.

[0029] When using this utility model, the overall collection height of the device is adjusted by the first telescopic cylinder 11. The action of the second telescopic cylinder 4 drives the suction pipe 3 to extend to the collection area, opens the airtight valve 81 corresponding to the sampling bottle 8 on the piston block 62, and starts the air pump 5 to perform the gas sampling operation. After the sampling bottle 8 is full, the airtight valve 81 is closed and the air pump 5 stops. Then the drive motor 71 is activated, causing the screw 61 to move the piston block 62 to the air hole 60 corresponding to the next sampling bottle 8, opens the airtight valve 81 on the sampling bottle 8, and the air pump 5 restarts to perform the gas collection operation. By continuously repeating the above operation, the rapid collection of furnace gas from multiple sampling bottles 8 can be achieved.
