[0026] Example:

[0027] Reference Figure 1-Figure 6The embodiment of the utility model provides a special CEMS sampling tube cleaning device, comprising a bottom plate 1 with a cavity inside, and also comprising: a booster water tank 2 with cleaning liquid added inside, fixedly installed on the top of the bottom plate 1; wherein, a cleaning pipe 3 is fixedly connected to the liquid outlet of the booster water tank 2 through a flange, a booster pump is installed on the booster water tank 2, and the pressure in the booster water tank 2 can be increased by the booster pump to increase the rate of liquid outflow in the tank, a valve is installed at the liquid outlet of the booster water tank 2, and the discharge of the cleaning liquid in the tank can be controlled by the valve, and a sealing sleeve 4 is fixedly connected to the cleaning pipe 3, and the shape of the sealing sleeve 4 is conical; two clamps 5 are connected to the cleaning pipe 3 through an adjusting part; wherein the adjusting part is used to drive the two clamps 5 to approach or move away from the sealing sleeve 4; two impact plates 7 are connected to the bottom plate 1 through an elastic member; wherein the impact plate 7 is pressed against the surface of the collection tube by the elastic force of the elastic member; an extrusion part is arranged in the cavity of the bottom plate 1; wherein the extrusion part is used to drive the two impact plates 7 to move away from each other.

[0028] Specifically, through the setting of the adjustment part, the distance between the two clamps 5 can be adjusted, so that the sampling tube connected to the sealing sleeve 4 can be clamped and fixed. With the cooperation of the two clamps 5 and the sealing sleeve 4, sampling tubes with different inner diameters can be fixed, and through the setting of the booster water tank 2, the pollutants accumulated inside the sampling tube can be flushed and removed. At the same time, through the cooperation of the elastic part and the extrusion part, the impact plate 7 can be driven to repeatedly impact the sampling tube, causing the sampling tube to vibrate, and the pollutants accumulated on the inner wall of the sampling tube can be shaken off, thereby improving the cleaning effect of the device on the sampling tube.

[0029] The adjustment part includes: a movable plate 6 with through holes on the surface, which is installed on the cleaning pipe 3; wherein, vertical plates 61 are fixedly connected to both sides of the top of the movable plate 6, and a double-headed screw 62 is rotatably connected to the vertical plate 61, and the threads on both sides of the outer wall of the double-headed screw 62 are designed in opposite directions; both sides of the outer wall of the double-headed screw 62 are threadedly connected to an adjustment plate 63, and two clamping plates 5 are respectively fixedly connected to the two adjustment plates 63, and the adjustment plate 63 is laterally slidably connected to the movable plate 6.

[0030] Specifically, when in use, the double-headed screw 62 is rotated to drive the two clamping plates 5 to move toward each other, so as to change the distance between the two clamping plates 5, so as to clamp and fix the sampling tubes with different inner diameters.

[0031] The elastic member includes a movable plate 8 and a spring 82. A movable groove 81 connected to the cavity of the bottom plate 1 is provided at the top, and the movable plate 8 is slidably connected in the movable groove 81; the two ends of the spring 82 are respectively fixedly connected to the cavity wall of the bottom plate 1 and the surface of the movable plate 8, and the impact plate 7 is fixedly connected to the top of the movable plate 8.

[0032] Specifically, when the movable plate 8 is squeezed by the protrusion 92, it slides along the inner wall of the movable groove 81 and drives the two impact plates 7 to move away from each other. At the same time, the spring 82 is compressed. When the movable plate 8 is not squeezed by the protrusion 92, the elastic force of the spring 82 can restore the two impact plates 7 to their initial positions and impact the surface of the sampling tube.

[0033] The extrusion part includes a motor 9 fixedly installed in the inner cavity of the bottom plate 1, and the output end of the motor 9 is fixedly connected to a turntable 91; both sides of the turntable 91 are fixedly connected to protrusions 92, and when the turntable 91 rotates, the protrusions 92 intermittently slide over the surface of the movable plate 8.

[0034] Specifically, by starting the motor 9, the output end of the motor 9 drives the turntable 91 and the protrusion 92 to rotate. When the protrusion 92 contacts the surface of the movable plate 8 and presses it, the movable plate 8 can be driven to drive the two impact plates 7 to move away from each other.

[0035] The cleaning pipes 3 are fixedly connected with slide rails 10 in pairs, and the through holes of the movable plate 6 are provided with slide grooves 11 in pairs, and the slide rails 10 are slidably connected in the slide grooves 11 .

[0036] Specifically, by providing the slide rail 10 and the slide groove 11 , the movable plate 6 can be guided so that it can only move laterally along the surface of the cleaning pipe 3 .

[0037] One end of the double-headed screw 62 is fixedly connected to a knob 12 , which is in the shape of a hexagonal prism.

[0038] Specifically, the setting of the knob 12 can facilitate the staff to apply force to rotate the double-headed screw 62, and the hexagonal design can play an anti-slip role.

[0039] Working principle: During use of the special CEMS sampling tube cleaning device, firstly, a side port of the CEMS sampling tube to be cleaned is sleeved on the liquid outlet end of the cleaning tube 3, and the sampling tube is pushed to sleeve it on the sealing sleeve 4, so that the sealing sleeve 4 is tightly inserted into the sampling tube, and the conical sealing sleeve 4 can simply fix and seal the sampling tubes with different inner diameters, and then the movable plate 6 is moved to a suitable position along the surface of the cleaning tube 3, and then the double-headed screw 62 is rotated. Under the action of the opposite threads, the double-headed screw 62 drives the two clamping plates 5 to move towards each other to change the distance between the two clamping plates 5, so as to clamp and fix the sampling tube sleeved on the sealing sleeve 4, and by adjusting the distance between the two clamping plates 5, the sampling tubes with different inner diameters can be fixed, so that the device can be suitable for the cleaning of sampling tubes with different inner diameters, and the elastic force of the spring 82 can also make the two impact plates 7 press against the surface of the sampling tube;

[0040] During cleaning, by opening the valve on the booster water tank 2, the liquid inside the booster water tank 2 can quickly enter the sampling tube through the liquid outlet and the cleaning tube 3 under the action of pressure, so as to flush and remove the pollutants accumulated inside the sampling tube, and prevent the accumulation of pollutants in the sampling tube from causing the tube to be blocked, so as to ensure the collection and circulation of flue gas, thereby ensuring the accuracy of the monitoring results;

[0041] And during the cleaning process, by starting the motor 9, the output end of the motor 9 drives the turntable 91 and the protrusion 92 to rotate. When the protrusion 92 contacts the surface of the movable plate 8 and squeezes it, the movable plate 8 slides along the inner wall of the movable groove 81 and drives the two impact plates 7 to move away from each other to move away from the CEMS sampling tube. At the same time, the spring 82 is compressed. When the protrusion 92 is separated from the surface of the movable plate 8, under the elastic force of the spring 82, the two impact plates 7 quickly return to their initial positions and impact the surface of the sampling tube. The turntable 91 drives the protrusion 92 to rotate continuously and cooperate with the spring 82, which can drive the impact plate 7 to repeatedly impact the sampling tube, causing the sampling tube to vibrate, and can vibrate off the pollutants accumulated on the inner wall of the sampling tube, thereby further improving the cleaning effect of the device on the sampling tube.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
