An on-site instrument measuring point abrasion-proof protection device comprises an upper layer abrasion-proof protection tile (1) and a lower layer abrasion-proof protection tile (2), wherein the upper layer abrasion-proof protection tile and the lower layer abrasion-proof protection tile are identical in structure, and the upper layer abrasion-proof protection tile and the lower layer abrasion-proof protection tile are fixedly connected through two clips (3) to form a hollow tubular structure; after the upper layer anti-abrasion protective tile and the lower layer anti-abrasion protective tile are fixedly connected, an in-situ instrument measuring rod (4) is inserted into a protective structure (5) cavity formed by the upper layer anti-abrasion protective tile and the lower layer anti-abrasion protective tile; the distance between the connecting flange (6) on the on-site instrument and the protective structure is 300mm. The utility model discloses be applied to boiler preheater's detection area.
Description
The technical field is as follows:
the utility model relates to an instrument measurement station abrasionproof protection device on spot.
Background art:
at present, after the Huaneng Jingyuan power plant boiler is transformed into a low-emission rotary air preheater, the boiler is doped, the coal quality is poor, the windward side of measuring points of detecting instruments such as the temperature of the boiler air preheater and an oxygen meter is seriously abraded, the measuring points are frequently replaced, and the maintenance cost is sharply increased.
The invention content is as follows:
the utility model aims at providing an instrument measurement station abrasionproof protection device on spot.
The above purpose is realized by the following technical scheme:
an on-site instrument measuring point anti-abrasion protection device comprises an upper layer anti-abrasion protection tile and a lower layer anti-abrasion protection tile, wherein the upper layer anti-abrasion protection tile and the lower layer anti-abrasion protection tile have the same structure, and are fixedly connected through two clamps to form a hollow tubular structure;
after the upper layer anti-abrasion protective tile and the lower layer anti-abrasion protective tile are fixedly connected, the on-site instrument measuring rod is inserted into a protective structure cavity formed by the upper layer anti-abrasion protective tile and the lower layer anti-abrasion protective tile;
the distance between the connecting flange on the on-site instrument and the protective structure is 300mm.
The anti-abrasion protection device for the in-situ instrument measuring point is a 14-star round steel pipe structure or a phi 32-star 4mm and phi 38-star 4mm semicircle 1Gr18Ni9TI anti-abrasion protection tile.
In the on-site instrument measuring point abrasion-proof protection device, the clamp adopts an adjustable hose clamp.
The utility model has the advantages that:
1. the utility model discloses make a device that can be used for protecting point measurement component on the spot, and be convenient for install and change. For sheathed thermocouples and thermal resistors, a protective device made of 14 x 2 stainless steel instrument tubes is welded at the connecting flange. For the oxygen meter, a detachable protection device (selected according to the sizes of the elements of the on-site measuring point) is manufactured on the probe side of the sensor by using phi 32X 4mm, phi 38X 4mm semi-circles 1Gr18Ni9TI anti-abrasion protection tiles and anti-abrasion clips.
The utility model discloses can be according to measurement station component actual motion operating mode, according to measurement station component wearing and tearing condition and measurement requirement, make and partly surround protector (protection windward side is easy wearing and tearing or partial wear) or surround protector entirely. The method is simple to operate, low in cost and suitable for severe working environments. Meanwhile, the service cycle of the temperature measuring point and the oxygen meter behind the measuring rod is protected to be prolonged, and the maintenance cost is reduced.
The utility model discloses it is high mainly to the flue gas dust-laden, especially mix to burn period to boiler flue gas system temperature, oxygen content measuring element's protection and wind smoke system use flange formula thermocouple thermal resistance to set up nonrust semi-circular steel pipe in flange department and get up the measurement station around the protection, and form the opening at the afterbody, do not influence the measuring accuracy.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Figure 2 is a schematic view of a guard structure.
Fig. 3 is a schematic view of the structure of the clip.
In the figure: 1. the measuring device comprises an upper-layer anti-abrasion protective tile, 2 a lower-layer anti-abrasion protective tile, 3 a clamp, 4 an in-situ instrument measuring rod, 5 a protective structure, 6 a connecting flange, 7 and a measuring point element.
The specific implementation mode is as follows:
example 1:
an on-site instrument measuring point anti-abrasion protection device comprises an upper anti-abrasion protection tile 1 and a lower anti-abrasion protection tile 2, wherein the upper anti-abrasion protection tile and the lower anti-abrasion protection tile have the same structure, and are fixedly connected through two clips 3 to form a hollow tubular structure; after the upper layer anti-abrasion protective tile and the lower layer anti-abrasion protective tile are fixedly connected, the on-site instrument measuring rod 4 is inserted into a cavity of a protective structure 5 consisting of the upper layer anti-abrasion protective tile and the lower layer anti-abrasion protective tile; the distance between the connecting flange 6 on the in-situ instrument and the protective structure is 300mm. According to the in-situ instrument measuring point anti-abrasion protection device, the upper layer anti-abrasion protection tile and the lower layer anti-abrasion protection tile are phi 32X 4mm or phi 38X 4mm semi-circle 1Gr18Ni9TI anti-abrasion protection tiles.
Example 2:
the anti-abrasion protection device for the in-situ instrument measuring point is characterized in that an adjustable hose clamp is adopted as a clamp. Upper abrasionproof protects the tile and lower floor abrasionproof and protects the tile and will form the protective structure of a pipe structure after the instrument measuring rod will be in the spot through two semi-circular structure's the tile lock together, then it has two checkposts to embolia respectively on this protection tube, it protects tile and lower floor abrasionproof to connect upper abrasionproof, laminate between the measuring rod on upper abrasionproof protects the inner ring face of tile and lower floor abrasionproof and protects the tile and the instrument in the spot this moment, thereby play the effect of a abrasionproof protection to the measuring rod of instrument in the spot, the life of instrument in the spot has been increased.
