In the control and treatment of pollutants, it mainly refers to the agent used to remove sulfur oxides (including SO2 and SO3) from exhaust gas. Desulfurizers are generally used in large quantities, so they are stored in large-volume storage cylinders. Desulfurizers will be damaged if they are placed in an uncomfortable environment such as humidity. Therefore, regular sampling and testing is required to determine whether the storage environment is normal, so a sampling device is required.

[0026] In a specific implementation, the shell cover 3 is fixedly mounted on the front side of the sampling rod 2, and a sampling port 8 is provided on the shell cover 3 and is located on the front side of the sampling cavity 7. The sampling cavity 7 can be protected by the shell cover 3, and the sampling port 8 can facilitate the introduction of desulfurizer into the sampling cavity 7.

[0027] In the specific implementation, such as Figure 3-Figure 6As shown, the automatic sampling component 4 is used to automatically complete the sampling of the desulfurizer. The automatic sampling component 4 is arranged in the sampling cavity 7. The automatic sampling component 4 includes a sealing limit block 401, a linkage block 402 and a control block 403. The sealing limit block 401 is clamped in the upper part of the sampling cavity 7 and is tightly attached to the inner side of the sampling port 8. Therefore, when the sealing limit block 401 is not in use, the upper part of the sampling cavity 7 that is actually used for sampling space can be filled, thereby ensuring that there will be no excess moisture in the area that may affect the subsequent detection results. A slide groove 9 is provided on the rear side of the sampling rod 2, and a track groove 10 is provided between the slide groove 9 and the sampling chamber 7. The control block 403 is clamped in the slide groove 9, and the linkage block 402 is installed between the sealing limit block 401 and the control block 403, and the linkage block 402 is clamped in the track groove 10. The control block 403 can move downward to drive the sealing limit block 401 to move downward through the linkage block 402, so that part of the space on the sampling chamber 7 can be exposed, and the desulfurizer can enter the sampling chamber 7 through the sampling port 8, thereby realizing sampling.

[0028] In a specific implementation, the linkage closing component 5 is used to automatically close the sampling port 8 after sampling to stop sampling and prevent the desulfurizer at other positions from entering the sampling chamber 7 during movement. The linkage closing component 5 includes a closing mechanism 501 and a braking mechanism 502. A boosting groove 11 is provided at the bottom of the inner wall of the sampling chamber 7, and a receiving groove 12 is provided at the bottom of the inner wall of the sampling port 8. A U-shaped conduction groove 13 is provided between the inner wall of the boosting groove 11 and the receiving groove 12, and a U-shaped conduction groove 13 is provided between the receiving groove 12 and the U-shaped conduction groove 13.

The closing mechanism 501 includes a closing piece 5011, a push rod 5012 and a sealing piece 5013. The closing piece 5011 is clamped in the accommodating groove 12, the sealing piece 5013 is clamped in the U-shaped conductive groove 13, the push rod 5012 is installed between the closing piece 5011 and the sealing piece 5013 and the push rod 5012 is clamped in the through hole. In the process of the sealing limit block 401 moving downward, the pressure rod 5021 can squeeze the installation limit spring. 5022 moves toward the pressurizing groove 11, so the pressure in the pressurizing groove 11 can be increased, and the sealing sheet 5013 and the push rod 5012 can be pushed upward under the action of pressure, so the push rod 5012 can push the closing sheet 5011 upward, and the closing sheet 5011 can close the sampling port 8 when it contacts the inner wall above the sampling port 8, so that the desulfurizer at other positions can be prevented from entering the sampling cavity 7 when the sampling rod 2 is taken out, and it can be ensured that no leakage will occur during the movement of the sampling rod 2.

[0029] In a specific implementation, the brake assembly 6 is used to control the use of the automatic sampling assembly 4 and the linkage closing assembly 5. The brake assembly 6 includes a mounting shell 601, a hydraulic cylinder 602 and a moving rod 603. The mounting shell 601 is mounted on the rear side of the fixed head, the hydraulic cylinder 602 is mounted in the mounting shell 601, the moving rod 603 is mounted at the output end of the hydraulic cylinder 602 and the moving rod 603 is mounted on one side of multiple control blocks 403. By starting the hydraulic cylinder 602 in the brake assembly 6, the hydraulic cylinder 602 can push the moving rod 603 downward, thereby simultaneously driving multiple control blocks 403 to move downward, thereby enabling multi-point sampling chamber 7 opening and closing control.

[0030] Furthermore, the boosting groove 11 and the U-shaped conduction groove 13 are filled with hydraulic oil 14 , and the pressure conduction can be ensured to be more stable through the hydraulic cylinder 602 .

[0031] Furthermore, a connecting rubber ring 15 is bonded to the inner wall of the U-shaped conducting groove 13 at the connection between the sampling rod 2 and the housing cover 3 , thereby preventing leakage at the connection between the sampling rod 2 and the housing cover 3 .

[0032] Furthermore, the width of the closing piece 5011 is equal to the width of the sampling port 8, so that the closing effect of the closing piece 5011 can be ensured to be good.

[0033] Furthermore, a fixed angle iron sheet 16 is installed on the front side of the positioning end 1, and a fixing hole 17 is opened on the fixed angle iron sheet 16. The fixed angle iron sheet 16 and the upper fixing hole 17 can be conveniently cooperated with the fixing parts to facilitate fixing the sampling device to the edge of the storage barrel, thereby ensuring stable sampling.

[0034] In this embodiment, the sampling device is arranged according to Figure 7 The state shown is set, the sampling rod 2 is inserted into the desulfurizer in the storage barrel, and then the fixed angle iron sheet 16 on one side of the positioning end head 1 is clamped to the edge of the storage barrel and fixed with a fixing piece. At this time, each sampling cavity 7 is located at a different depth position, and then the hydraulic cylinder 602 is started. The hydraulic cylinder 602 can push the moving rod 603 downward, and the moving rod 603 and the control block 403 move downward, which can drive the sealing limit block 401 to move downward through the linkage block 402, so that part of the space on the sampling cavity 7 can be exposed, and the desulfurizer can enter the sampling cavity 7 through the sampling port 8, so that sampling can be realized. During the downward movement of the sealing limit block 401, the pressure rod 5021 can squeeze the installation limit spring 5022 and move it toward the booster The sampling port 8 can be closed when the closing piece 5011 contacts the inner wall above the sampling port 8, thereby preventing the desulfurizer at other positions from entering the sampling cavity 7 when the sampling rod 2 is taken out, and ensuring that the sampling rod 2 will not leak during the movement of the sampling rod 2. Subsequently, the sampling rod 2 is taken out of the desulfurizer, and the hydraulic cylinder 602 is retracted by controlling the external device. When the closing piece 5011 and the sealing limit block 401 are reset, the sampled desulfurizer can be poured out.

[0035] Embodiment 2 This embodiment is further optimized on the basis of the above embodiment, and the same parts as the above technical solution will not be repeated here. Figure 8-Figure 10 As shown, in order to better implement the present invention, the following configuration is particularly adopted: In the specific implementation, such as Figure 8As shown, an adjustment component 18 for adjusting the initial setting position of the sampling rod 2 is provided on one side of the positioning end 1, and the adjustment component 18 includes an adjustment cylinder 1801, a mounting plate 1802 and a connecting block 1803. The mounting plate 1802 is located on one side of the fixed angle iron sheet 16, and the adjustment cylinder 1801 is installed on one side of the mounting plate 1802. The connecting block 1803 is arranged on the fixed angle iron sheet 16 and the connecting block 1803 is installed on the output end of the adjustment cylinder 1801. The distance between the positioning end 1 and the mounting plate 1802 can be conveniently controlled by adjusting the cylinder 1801, so that the sampling position can be accurately controlled. A positioning angle iron sheet 19 is installed on one side of the mounting plate 1802, and a positioning hole 20 is opened on the positioning angle iron sheet 19. The adjustment component 18 can be conveniently fixed to the edge of the storage tube through the positioning angle iron sheet 19 and the positioning hole 20, so that the sampling tube can be vertically inserted into the storage tube.

[0036] Further, such as Fig. 9 As shown, a connecting piece 21 is installed on one side of the fixed angle iron piece 16, and a connecting groove 22 is provided on one side of the connecting block 1803. The connecting piece 21 is clamped in the connecting groove 22, so that the fixed angle iron piece 16 can be flexibly connected to the connecting block 1803. A fixing component 23 for fixing the connecting piece 21 is provided in the connecting block 1803. The fixing component 23 includes a metal clamping block 2301 and a mounting spring 2302. A groove 24 is provided above the inner wall of the connecting groove 22, and a key groove 25 is provided above the connecting piece 21. The metal clamping block 2301 is installed on the inner wall of the groove 24 through the mounting spring 2302. The upper and lower ends of the metal clamping block 2301 are respectively clamped in the groove 24 and the key groove 25. Therefore, the connecting piece 21 can be fixedly connected to the connecting block 1803 through the metal clamping block 2301, and an electromagnetic block is installed on the inner wall of the groove 24 The distance between the electromagnetic block and the metal clamping block 2301 is greater than the depth of the key slot 25. The electromagnetic block can be used to easily adjust the position of the metal clamping block 2301 from the inside, so that the connection effect between the connecting piece 21 and the connecting block 1803 can be easily released. The fixing component 23 can ensure that the fixed angle iron sheet 16 can be stably connected to the connecting block 1803, and the fixed angle iron sheet 16 and the adjusting component 18 can be quickly separated when the adjusting component 18 is not needed. When separating, the electromagnetic block is connected to an external power supply. The electromagnetic block can generate magnetic attraction and attract the metal clamping block 2301, so the metal clamping block 2301 can squeeze the installation spring 2302 and move upward. When the metal clamping block 2301 is completely removed from the key slot 25, there is no fixed connection relationship between the connecting piece 21 and the connecting block 1803, so the adjusting component 18 can be disassembled.

[0037] In this embodiment, the oil cylinder 1801 is first controlled and adjusted, so that the oil cylinder 1801 can be in a telescopic state, and a space is left between the positioning end 1 and the mounting plate 1802, so that the distance between the sampling position and the edge of the storage tube can be adjusted. After the adjustment is completed, the control oil cylinder is closed, and then the sampling rod 2 is inserted into the desulfurizer and the fixed angle iron sheet 16 is clamped to the edge of the storage tube. Then, the fixed angle iron sheet 16 is fixed with a fixing piece, so that it can be ensured that the sampling rod 2 is vertically inserted into the desulfurizer, so that the sampling position can be accurate, and then it can be carried out. During the sampling operation, the connecting piece 21 and the connecting block 1803 are fixedly connected by the metal clamping block 2301 which is clamped in the key slot 25. When the adjusting component 18 and the fixed angle iron piece 16 need to be disassembled, the electromagnetic block is connected to an external power supply. The electromagnetic block can generate magnetic attraction and attract the metal clamping block 2301, so that the metal clamping block 2301 can squeeze the mounting spring 2302 and move upward. When the metal clamping block 2301 is completely removed from the key slot 25, there is no fixed connection between the connecting piece 21 and the connecting block 1803, so the adjusting component 18 can be disassembled.
