Example 1
Referring to fig. 3, the present embodiment provides a pulverized coal temperature measuring device, which includes a primary element 10, a sheath 20, a sealing member and an adapter member.
In the orientation of fig. 3, the top end face of the sheath 20 is provided with a sealing surface 50 with a seal.
For reference, the sealing surface 50 may be a metal sealing surface.
By providing the sealing surface 50, the sheath 20 can be sealed, and leakage of pulverized coal after the sheath 20 is damaged can be avoided to some extent.
The seal comprises a first sealing joint 31.
The first sealing head may be an internally threaded sealing joint, in particular it may be a 1/4 female threaded joint.
The adapter comprises a first adapter 41.
The first adapter 41 may be a ferrule fitting, in particular it may be a 3mm diameter ferrule fitting (correspondingly, the primary element 10 is also 3mm in diameter). In addition, ferrule fittings of other diameters may be provided as desired.
One end of the primary element 10 is located within the sheath 20 and the other end of the primary element 10 extends out of the sheath 20 and is adapted to pass through the first sealing joint 31 and the first adapter 41 in sequence.
A disc 60 is further connected to the end of the primary element 10 away from the sheath 20, and the disc 60 is provided with a binding post 61 (see fig. 1).
The disc 60 may be made of plastic, i.e. the corresponding disc 60 is a plastic disc 60.
The number of the posts 61 provided on the disk 60 may be 3 or other numbers as needed.
Further, the disc 60 may be further provided with a fixing hole, and the sheath 20 is provided with a nut, and the fixing hole is fixedly connected with the nut through a screw (refer to fig. 1 and 2).
For reference, the fixing holes include a first fixing hole 621 and a second fixing hole 622, the nuts include a first nut 211 and a second nut 212, and the screws include a first screw 221 and a second screw 222.
The first fixing hole 621 and the first nut 211 are coupled by the first screw 221, and the second fixing hole 622 and the second nut 212 are coupled by the second screw 222.
The first nut 211 and the second nut 212 are fixed to the sheath 20, and preferably symmetrically fixed to the outer wall of the sheath 20. Accordingly, the first fixing holes 621 and the second fixing holes 622 are spaced apart on the disk 60.
The primary element 10 can be effectively fixed in the sheath 20 by the above-mentioned fixing holes, nuts and screws.
It should be noted that, in some embodiments, the fixing holes, nuts and screws may not be provided, and the primary element 10 may also perform a certain fixing function through the first sealing head and the first adapter 41.
In addition, in other embodiments, the number of the fixing holes, the nuts, and the screws may be 1, 3, or more, and is not excessively limited herein.
The inventors propose: when the pulverized coal temperature measuring primary element 10 in the prior art is used, maintenance personnel can find out only when the sheath 20 is damaged, thereby causing the temperature primary element 10 to be damaged and the temperature measurement to be abnormal.
Based on this, the present embodiment is further improved with respect to the existing pulverized coal temperature measuring device, and specifically, the pulverized coal temperature measuring device in this embodiment further includes an air source pipe 71 and a pressure switch 72.
The seal also includes a second sealing joint 32 and the adapter includes a second adapter 42.
For reference, the second seal head may also be an internally threaded seal joint, and specifically, it may be a 1/4 female threaded joint.
The second adapter 42 may be a ferrule fitting, in particular, it may be a ferrule fitting having a diameter of 8mm (accordingly, the diameter of the air source tube 71 described below may be 8 mm). In addition, ferrule fittings of other diameters may be provided as desired.
One end of the air source tube 71 is communicated with the second sealing joint 32 through the first adapter 41, and the other end of the air source tube 71 is connected with the pressure switch 72.
The pressure switch 72 detects the change of the pressure in the sheath 20, so that the damage condition of the sheath 20 can be effectively monitored and controlled.
Further, the pulverized coal temperature measuring device further includes an indicator lamp 73 and a power supply 74;
the pressure switch 72 is connected with the indicator lamp 73, and the pressure switch 72 and the indicator lamp 73 are both connected with the power supply 74.
The indicator lamp 73 may be an LED lamp.
It should be noted that, the specific usage and operation principle of the pressure switch 72 can be referred to the prior art, and will not be described herein in detail.
In this embodiment, the normally closed contact of the pressure switch 72 (i.e. the node is closed when the pressure is low) is connected in series with the LED indicator lamp 73 and the power supply 74 (e.g. 24V). When the sheath 20 breaks, the pressure inside the sheath 20 is reduced, the pressure switch 72 detects the pressure reduction, the node is closed, and the LED lamp is on, so that maintenance personnel can timely find that the sheath 20 is damaged.
Further, the pulverized coal temperature measuring device further includes a compressed gas pipe 81.
The seal also includes a third sealing joint 33 and the adapter includes a third adapter 43.
For reference, the third seal head may be an internally threaded seal joint, and specifically, may be a 1/4 female threaded joint.
The third adapter 43 may be a ferrule fitting, in particular, a ferrule fitting having a diameter of 8mm (accordingly, the diameter of the compressed gas pipe 81 described below may be 8 mm). In addition, ferrule fittings of other diameters may be provided as desired.
One end of the compressed gas pipe 81 is communicated with the third sealing joint 33 through the third adapter 43, and the other end of the compressed gas pipe 81 is used for externally connecting a compressed gas supply device.
A pressure reducing valve 82 may be further connected between the third adaptor 43 and the compressed gas pipe 81.
On the other hand, since the compressed air is introduced, the pressure inside the sheath 20 is higher than the external pressure, and the pulverized coal cannot enter the sheath 20, so that the thermal resistance primary element 10 is further prevented from being damaged or the pulverized coal is prevented from leaking.
In summary, the pulverized coal temperature measuring device provided by the utility model can enable maintenance personnel to timely find the damage of the sheath 20 by observing the LED lamp. When the sheath 20 is broken, the pulverized coal cannot enter the sheath 20, and the temperature primary element 10 is not damaged.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
