Description

Technical Field

[0001] The utility model relates to the technical field of flue gas analyzers, in particular to a portable multifunctional flue gas analyzer for boilers. Background Art

[0002] A flue gas analyzer is a device specifically designed to measure and analyze the various components in flue gas. It comes in two main types: handheld and fixed, suitable for different scenarios. Handheld flue gas analyzers are easy to carry and operate, and are primarily used for monitoring pollution emissions from small fuel and gas boilers or environments near pollution sources. Fixed flue gas analyzers are typically installed near pollution sources for real-time online monitoring.

[0003] When the flue gas is detected by a handheld flue gas analyzer, the flow guide probe of the flue gas detector is inserted into equipment such as a boiler to collect and analyze the flue gas. For example, the Chinese utility model patent disclosed by publication number CN218726838U is a handheld flue gas analyzer. The application includes a flue gas analyzer body, a control panel and a display screen are sequentially arranged on the front side of the flue gas analyzer body, arc-shaped hand-held slots are symmetrically provided on the left and right sides of the flue gas analyzer body, an elastic band is installed on the rear side of the flue gas analyzer body, and the upper and lower ends of the elastic band are fixedly connected to the upper and lower ends of the rear side of the flue gas analyzer body respectively, a rotating assembly is installed on the upper surface of the flue gas analyzer body, and a lifting assembly is installed on the top of the rotating assembly. This application can be conveniently used according to the needs of detection. The detection head can be adjusted in height and length by telescopic adjustment, and in angle by rotation, which expands its scope of use. However, when performing real-time flue gas detection on equipment such as boilers, the detection head needs to be inserted into the boiler or other equipment through the inspection port or observation port of the boiler to complete the collection and detection of flue gas. Therefore, when the detection head is inserted into the boiler or other equipment, this application cannot achieve a seal on the inspection port or observation port, which can easily lead to the overflow of high-temperature flue gas, causing environmental pollution and personal injury. At the same time, some existing flue gas analyzers will be equipped with a sealing block on the detection head. In order to facilitate the adjustment of the length of the detection head inserted into the boiler, the sealing block is movably installed on the outside of the detection head, resulting in a gap between the detection head and the sealing block, which can also easily lead to the overflow of high-temperature flue gas.

[0025] like Figures 1-6As shown, the utility model provides a portable multifunctional flue gas analyzer for boilers, including an analyzer body 1 and a handle 2, a flow guide probe 3 is fixedly installed on one side of the handle 2, and the side of the handle 2 opposite to the flow guide probe 3 is movably connected to the analyzer body 1 through a connecting pipe 4, a sealing cone 5 is movably installed on the outside of the flow guide probe 3, the sealing cone 5 includes a first cone 6, a second cone 7 is fixedly installed on one side of the first cone 6, two sealing blocks 8 are movably installed between the first cone 6 and the second cone 7, and two arc-shaped clamping plates 9 are movably installed on the outside of the first cone 6 and the second cone 7.

[0026] like Figure 2-Figure 5 As shown, two half-width screw grooves 10 are provided on one side of the first cone 6, and two half-width screw grooves 10 are also provided on the side of the second cone 7 relative to the first cone 6. The first cone 6 located between the two half-width screw grooves 10 is also provided with a mounting groove 13, and the second cone 7 is also provided with a mounting groove 13 on the side relative to the first cone 6. Half-width countersunk holes 11 are provided on the top and bottom of the mounting groove 13. A plurality of screw grooves 12 are also provided on one side of the first cone 6. Splitting the sealing cone 5 into the first cone 6 and the second cone 7 can facilitate the assembly and maintenance of the sealing block 8 and the arc-shaped clamping plate 9. The sealing block 8 is fixed with a mounting hole 11. A push rod 15 is installed, and the end of the push rod 15 away from the sealing block 8 passes through the half-width countersunk hole 11 and extends to the outside of the first cone 6 and the second cone 7. The push rod 15 located in the half-width countersunk hole 11 is fixedly installed with a snap ring 20. The push rod 15 located above the snap ring 20 is provided with a plurality of snap grooves 16. The push rod 15 located between the bottom of the half-width countersunk hole 11 and the snap ring 20 is sheathed with a first compression spring 14. The sealing block 8 is installed between the two mounting grooves 13 through the push rod 15, and with the help of the force of the first compression spring 14, the two sealing blocks 8 can be kept in a separated state under normal circumstances.

[0027] like Figure 2 、 Figure 4 As shown in Figure 6, a limiting screw 17 is threadedly connected between the two half-width screw grooves 10, and a pull ring 18 is fixedly installed at the middle position of the outer side of the arc-shaped clamping plate 9. The arc-shaped clamping plate 9 is inserted and installed on the outer side of the first cone 6 and the second cone 7, and the arc-shaped clamping plate 9 located in the pull ring 18 is inserted and installed on the outer side of the limiting screw 17. The limiting screw 17 located between the end of the limiting screw 17 and the arc-shaped clamping plate 9 is equipped with a second compression spring 19, and the notches at both ends of the arc-shaped clamping plate 9 are respectively clamped in the corresponding clamping grooves 16. The two arc-shaped clamping plates 9 can be clamped in the corresponding clamping grooves 16 at both ends with the help of the pressure of the second compression spring 19, thereby limiting the sealing block 8 by limiting the push rod 15.

[0028] It should be noted that the present invention is a portable multifunctional flue gas analyzer for boilers. When adjusting the length of the flow guide probe 3 inserted into the boiler according to the detection depth, it is only necessary to slide the first cone 6 and the second cone 7 on the outside of the flow guide probe 3 through the through hole at the center position, and then, the two push rods 15 can be pressed relative to each other with two fingers of one hand, so that the two push rods 15 move in the corresponding two half-width countersunk holes 11 respectively, and drive the two sealing blocks 8 to move relative to each other in the two mounting grooves 13. At the same time, when the push rod 15 moves, the outer side of the push rod 15 pushes the arc-shaped card plate 9 to move to one side, and makes the multiple card slots 16 on the outer side of the push rod 15 snap into the corresponding arc-shaped card slots in sequence. The groove at one end of the plate 9 is inserted into the groove, thereby realizing the real-time limit of the push rod 15, and the push rod 15 simultaneously compresses the first compression spring 14 toward the bottom of the half-width countersunk hole 11 through the snap ring 20, so that the semicircular grooves on the opposite side of the two mounting grooves 13 are squeezed on the outside of the diversion probe 3, thereby fixing the first cone 6 and the second cone 7 on the outside of the diversion probe 3, and sealing the gap between the through holes in the first cone 6 and the second cone 7 and the diversion probe 3. Then, the diversion probe 3 can be inserted into the boiler through the observation port of the boiler by holding the handle 2, and the observation port is sealed by the first cone 6, so that the flue gas in the boiler can be collected and analyzed through the diversion probe 3 and the analyzer body 1;

[0029] When the position of the first cone 6 needs to be readjusted, it is only necessary to pull the pull rings 18 on one side of the two arc-shaped clamping plates 9 to one side, so that the pull rings 18 drive the arc-shaped clamping plates 9 to move to one side, and the notches at both ends of the arc-shaped clamping plates 9 are disengaged from the corresponding clamping grooves 16, so that the push rod 15 can drive the sealing block 8 to reset with the help of the force of the first compression spring 14 to stretch and rebound, so that the first cone 6 and the second cone 7 can be slidably adjusted on the guide tube 3.
