Description

Technical Field

[0001] This utility model relates to the field of instrument installation technology, specifically a translationally adjustable laser analyzer installation structure. Background Technology

[0002] In current ultra-low emission measurements, laser analyzers are generally used. To ensure measurement accuracy and representativeness of the sample gas, two mounting holes are typically made on the side wall of the chimney to install the laser analyzer's transmitting and receiving units. The installation requirements for the laser analyzer include that the two mounting holes on the chimney side wall must be concentric, and the mounting flanges on both sides must be parallel. This ensures that the laser beam emitted by the laser analyzer's transmitting unit is received by the receiving window of the laser analyzer's receiving unit, thereby guaranteeing normal measurement and accuracy.

[0003] Existing metallurgical and coal chemical chimneys typically have large diameters. When installing the laser analyzer by directly drilling holes in the chimney sidewall, it is difficult to ensure that the two mounting holes are concentric. Furthermore, for some renovation projects, it is necessary to drill holes in existing large-diameter chimneys, and the two mounting holes are prone to eccentricity, which is not conducive to the smooth installation of the laser analyzer. Utility Model Content

[0004] The purpose of this invention is to provide a translationally adjustable laser analyzer mounting structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable laser analyzer mounting structure includes a mounting module one and a mounting module two. The mounting module one and the mounting module two have the same structure. The mounting module one includes an intermediate flange, a sliding flange, and a flange assembly. The intermediate flange is disposed on the flange assembly and is located between the sliding flange and the flange assembly. The laser analyzer emitting unit and the laser analyzer receiving unit are both located on the side of the corresponding sliding flange away from the intermediate flange.

[0007] The sliding flange has four straight slots, and the intermediate flange is fixedly connected with four carrier wires that pass through adjacent straight slots. The intermediate flange is provided with two adjustment mechanisms. The four carrier wires are arranged in a ring at equal intervals on the end face of the intermediate flange, and the four straight slots are arranged in a ring at equal intervals on the end face of the sliding flange.

[0008] Furthermore, the diameter of the carrier wire is equal to the width of the straight slot hole.

[0009] Furthermore, the adjustment mechanism includes an adjustment stop and a positioning screw;

[0010] The adjusting stop is fixedly connected to the intermediate flange;

[0011] The positioning screw is screwed onto the adjusting block, and the end of the positioning screw contacts the annular side of the translation flange.

[0012] Furthermore, the positioning screw is parallel to the straight slot hole.

[0013] Furthermore, the flange assembly includes a process flange and a short pipe;

[0014] The process flange is fixedly connected to the intermediate flange by bolts;

[0015] The short pipe is fixedly connected to the process flange, and the short pipe is located on the side of the process flange away from the intermediate flange.

[0016] Furthermore, the intermediate flange is fixedly connected to an insertion tube that passes through the inside of the short pipe, and the insertion tube is located on the side of the intermediate flange away from the translation flange.

[0017] Preferably, the short pipe is fixedly connected with a reinforcing steel plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The sliding flange has four straight slots. First, the flange assembly is fixed into the mounting holes on the chimney sidewall. Then, the intermediate flange is fixed to the flange assembly with bolts. Next, the sliding flange is placed against the intermediate flange, allowing the four carrier wires to pass through the four straight slots. When installing the intermediate flange and flange assembly, the angle between them can be determined so that the straight slots are perpendicular to the horizontal plane when the sliding flange is installed on the intermediate flange. This allows the sliding flange to move up and down relative to the intermediate flange, adjusting the vertical height of the laser analyzer emitting unit. Simultaneously, the straight slots of mounting module two are parallel to the horizontal plane, allowing the sliding flange of mounting module two to move left and right relative to the intermediate flange, adjusting the horizontal position of the laser analyzer receiving unit. If the two mounting holes are not concentric during installation, the vertical position of the laser analyzer emitting unit and the horizontal position of the laser analyzer receiving unit can be adjusted to align them, facilitating successful installation of the laser analyzer.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 In this embodiment of the present invention, a translationally adjustable laser analyzer mounting structure includes a first mounting module 100 and a second mounting module 200. The first mounting module 100 and the second mounting module 200 have the same structure. The first mounting module 100 includes an intermediate flange 110, a translation flange 120, and a flange assembly 130. The intermediate flange 110 is disposed on the flange assembly 130 and is located between the translation flange 120 and the flange assembly 130. A laser analyzer emitting unit 300 is fixedly disposed on the translation flange 120 of the first mounting module 100. A laser analyzer receiving unit 400 is fixedly disposed on the translation flange 120 of the second mounting module 200. Both the laser analyzer emitting unit 300 and the laser analyzer receiving unit 400 are located on the side of the corresponding translation flange 120 away from the intermediate flange 110.

[0028] The sliding flange 120 has four straight slots 121. The intermediate flange 110 is fixedly connected with four carrier wires 111 that pass through adjacent straight slots 121. The diameter of the carrier wires 111 is equal to the width of the straight slots 121. The intermediate flange 110 is provided with two adjustment mechanisms 140. The four carrier wires 111 are arranged equidistantly in an annular pattern on the end face of the intermediate flange 110, and the four straight slots 121 are arranged equidistantly in an annular pattern on the end face of the sliding flange 120.

[0029] Specifically, the flange assembly 130 can be fixed in the mounting hole opened on the side wall of the chimney. Then, the intermediate flange 110 is fixed to the flange assembly 130 with bolts. The sliding flange 120 is then placed against the intermediate flange 110, so that the four carrier wires 111 pass through the four straight slots 121 respectively. When installing the intermediate flange 110 and the flange assembly 130, the angle between them can be adjusted so that when the sliding flange 120 is installed on the intermediate flange 110, the straight slots 121 are perpendicular to the horizontal plane. When the translation flange 120 moves relative to the intermediate flange 110, the straight slot hole 121 can move up and down relative to the carrier wire 111, thereby adjusting the vertical height of the laser analyzer emitting unit 300. When the mounting module 200 is fixed, the straight slot hole 121 of the mounting module 200 is made parallel to the horizontal plane. When the translation flange 120 of the mounting module 200 moves relative to the intermediate flange 110, the straight slot hole 121 of the mounting module 200 moves horizontally relative to the carrier wire 111, thereby adjusting the horizontal position of the laser analyzer receiving unit 400.

[0030] If the two mounting holes are not concentric during installation, the vertical position of the laser analyzer emitting unit 300 and the horizontal position of the laser analyzer receiving unit 400 can be adjusted to align the laser analyzer emitting unit 300 and the laser analyzer receiving unit 400, which will facilitate the smooth installation of the laser analyzer.

[0031] Example 1

[0032] like Figure 2 and Figure 4 As shown, in this embodiment, the adjustment mechanism 140 includes an adjustment stop 141 and a positioning screw 142;

[0033] The adjusting block 141 is fixedly connected to the intermediate flange 110. The adjusting block 141 can be fixed to the intermediate flange 110 by screws or the like. The positioning screw 142 is screwed onto the adjusting block 141. The end of the positioning screw 142 contacts the annular side of the translation flange 120. The positioning screws 142 of the two adjusting mechanisms 140 abut against the translation flange 120, which can fix the translation flange 120 relative to the intermediate flange 110 and prevent the translation flange 120 from moving up and down or left and right relative to the intermediate flange 110. The positioning screw 142 is parallel to the straight slot hole 121.

[0034] In practice, when it is necessary to adjust the position of the translation flange 120, the positioning screw 142 of the top adjusting mechanism 140 can be rotated first to separate the top positioning screw 142 from the translation flange 120. Then, the positioning screw 142 of the bottom adjusting mechanism 140 can be rotated. When the positioning screw 142 moves along the inside of the adjusting block 141, the positioning screw 142 can drive the translation flange 120 to move up or down, thereby adjusting the position of the translation flange 120. After the adjustment is completed, the positioning screw 142 of the top adjusting mechanism 140 can be rotated in the opposite direction to make the positioning screw 142 abut against the translation flange 120 to position the translation flange 120. Then, the connecting nut can be screwed on the carrier wire 111 to make the nut abut against the translation flange 120, and the translation flange 120 can be completely fixed to the intermediate flange 110.

[0035] like Figure 2 and Figure 3 As shown, in this embodiment, the flange assembly 130 includes a process flange 131 and a short pipe 132;

[0036] The process flange 131 is fixedly connected to the intermediate flange 110, and the short pipe 132 is fixedly connected to the process flange 131. The short pipe 132 is located on the side of the process flange 131 away from the intermediate flange 110. A reinforcing steel plate 500 is fixedly connected to the short pipe 132, and the reinforcing steel plate 500 is sleeved on the short pipe 132.

[0037] In practice, during installation, the short pipe 132 with the reinforcing steel plate 500 is inserted into the mounting hole in the chimney wall. After adjusting the angle of the process flange 131, the short pipe 132 is fixed to the chimney side wall with concrete. Then, the reinforcing steel plate 500 is welded and fixed to the short pipe 132, and the reinforcing steel plate 500 is fixed to the inner wall of the chimney with bolts, etc., which helps to improve the stability and sealing of the installation.

[0038] Example 2

[0039] Based on Example 1, such as Figure 2-5 As shown, in this embodiment, the intermediate flange 110 is fixedly connected to an insertion pipe 112 that passes through the inside of the short pipe 132. The insertion pipe 112 is located on the side of the intermediate flange 110 away from the translation flange 120. The insertion pipe 112 can pass through the process flange 131 and the inside of the short pipe 132, and the insertion pipe 112 can extend into the inside of the chimney.

[0040] In practical implementation, the emitting end of the laser analyzer emitting unit 300 and the receiving end of the laser analyzer receiving unit 400 can both be set inside the corresponding insertion tube 112. In this way, by setting the emitting end of the laser analyzer emitting unit 300 and the receiving end of the laser analyzer receiving unit 400 inside the chimney, it is ensured that the distance between the emitting end and the receiving end is within the effective measurement optical path. Moreover, the insertion tube 112 can be used to shield and protect the emitting end of the laser analyzer emitting unit 300 and the receiving end of the laser analyzer receiving unit 400, preventing the process sample gas from contacting the optical windows in the emitting end and the receiving end and damaging the optical windows.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
