Description

Technical Field

[0001] The invention belongs to the technical field of electrode boiler corrosion monitoring, and in particular relates to an electrode boiler corrosion online monitoring sensor. Background Art

[0002] Electrode boilers convert electrical energy into thermal energy, which is then heated to form steam. Powered by electricity, they are widely used in small factories, large kitchens, and other applications. Compared to other energy sources, such as biomass, coal, or fuel oil, they require no purification of combustion products and are easy to operate. Because boiler water contains calcium and magnesium ions, after evaporation over long periods of use, these ions adhere to the inner walls of the electrode boiler as scale, affecting the boiler's thermal efficiency. Therefore, a chemical must be added to the boiler water to prevent scale from condensing, and the scale must be drained out of the boiler through a drain. However, the effects of calcium and magnesium ions and the chemical can cause corrosion on the inner walls of the electrode boiler. This increased corrosion reduces the lifespan of the electrode boiler and significantly reduces its safety. Summary of the Invention

DETAILED DESCRIPTION

[0031] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0032] The present invention discloses an electrode boiler corrosion online monitoring sensor, such as Figure 1-12As shown, it includes a guide rail 200, an assembly base 400, a vertical adjustment mechanism, and a walking monitoring mechanism 300. The guide rail 200 is arranged in a spiral form, extending in a vertical direction. The guide rail 200 is mounted on the outside of the electrode boiler 100. The lower end of the guide rail 200 is rotatably connected to the assembly base 400, and the upper end of the guide rail 200 is connected to the upper end of the electrode boiler 100 via the vertical adjustment mechanism. The walking monitoring mechanism 300 of the present invention is assembled on the guide rail 200. The walking monitoring mechanism 300 moves along the guide of the guide rail 200, and the monitoring end of the walking monitoring mechanism 300 contacts the outer peripheral wall of the electrode boiler 100. The working principle and advantages of the present invention are: the present invention achieves the purpose of the walking monitoring mechanism 300 performing corrosion monitoring on the electrode boiler 100 by controlling the walking monitoring mechanism 300 to move on the guide rail 200. Furthermore, because the guide rail 200 extends in a spiral configuration, the traveling monitoring mechanism 300 spirals along the circumference of the electrode boiler 100 during monitoring, continuously monitoring different areas of the circumferential wall of the electrode boiler 100. The present invention allows the guide rail 200 to be rotated by a certain angle to change the trajectory of the traveling monitoring mechanism 300's spiral motion; the vertical adjustment mechanism can also be adjusted to change the pitch of the guide rail 200; and both of these guide rail 200 adjustment methods can be combined to achieve comprehensive and accurate monitoring of the circumferential wall of the electrode boiler 100 by the traveling monitoring mechanism 300. The present invention eliminates the need for monitoring personnel to manually inspect the electrode boiler 100. Instead, the walking monitoring mechanism 300 can be controlled to monitor the electrode boiler 100 in a timely manner based on the drainage water quality, circulating water quality, and liquid level discharge of the electrode boiler 100. Specifically, when the water quality monitor detects that the drainage water quality, circulating water quality, and liquid level discharge exceed a predetermined range, this indicates corrosion within the electrode boiler 100. The walking monitoring mechanism 300 can then be controlled to monitor and locate the location and extent of the corrosion. Maintenance personnel can adjust the amount of reagent added to the boiler water and / or repair the corroded areas of the electrode boiler 100 based on the monitoring results of the walking monitoring mechanism 300. As can be seen from the foregoing, the present invention can effectively monitor the corrosion of the inner circumferential wall of the electrode boiler 100, improving the accuracy and comprehensiveness of monitoring. Operators can adjust the amount of reagent added to the boiler water based on the monitored conditions, and it is convenient for maintenance personnel to subsequently perform targeted repairs on the corroded areas of the electrode boiler 100, thereby improving the safety of the electrode boiler 100 and extending the service life of the electrode boiler 100.

[0033] As a preferred embodiment of the present invention, Figure 2As shown, the guide rail 200 includes a guide rail body 201, and fixed ears 203 are respectively constructed at the upper and lower ends of the guide rail body 201. The upper fixed ear 203 is connected to the upper vertical arm 207, and the lower fixed ear 203 is connected to the lower vertical arm 204. The lower vertical arm 204 is connected to the assembly base 400, and the upper vertical arm 207 is connected to the vertical adjustment mechanism. Figure 4 As shown, the assembly base 400 of this embodiment includes an annular base 401, which is fixedly mounted on the ground, with its axis coinciding with the axis of the electrode boiler 100. An annular groove 402 is defined on the upper end surface of the annular base 401, with its axis coinciding with the axis of the annular base 401. In this embodiment, a sliding block 205 is fixedly connected to the lower end of the lower vertical arm 204. Limiting grooves 206 are formed on two opposing sides of the sliding block 205. The sliding block 205 is slidably assembled within the annular groove 402, and the limiting grooves 206 are slidably connected to the corresponding inner walls of the annular groove 402. The operating principle and advantages of this embodiment are that the guide rail 200 can be rotated a certain angle along the axis of the electrode boiler 100, and the lower end of the guide rail 200, via the lower vertical arm 204, drives the sliding block 205 to slide along the annular groove 402. This embodiment controls the vertical adjustment mechanism to move the upper end of the guide rail 200 vertically, thereby stretching or compressing the guide rail 200 vertically, ultimately changing the pitch of the guide rail 200. This changes the trajectory of the spiral motion of the traveling monitoring mechanism 300 on the guide rail 200, achieving all-round corrosion monitoring of the electrode boiler 100.

[0034] As a preferred embodiment of the present invention, Figure 2 、 3As shown, the vertical adjustment mechanism includes a radial beam 208 and a vertical lead screw 209. The radial beam 208 is fixedly connected to the upper end of the upper vertical arm 207, and the vertical lead screw 209 is threadedly connected to the radial beam 208. The axis of the vertical lead screw coincides with the axis of the electrode boiler 100. The lower end of the vertical lead screw 209 is rotationally connected to the electrode boiler 100. A first operating handwheel 210 is mounted on the upper end of the vertical lead screw 209. In this embodiment, by rotating the first operating handwheel 210, it rotates the vertical lead screw 209. During rotation, the vertical lead screw 209 drives the upper end of the guide rail 200 to move vertically, thereby achieving the purpose of adjusting the pitch of the guide rail 200. In this embodiment, an internally threaded sleeve 211 is rotatably connected to the radial beam 208. The vertical lead screw 209 is threadedly connected to the internally threaded sleeve 211. A locking bolt 212 is threadedly connected to the radial beam 208. One end of the locking bolt 212 abuts against the outer peripheral wall of the internally threaded sleeve 211 along the radial direction of the internally threaded sleeve 211. The working principle and advantages of this embodiment are: when the pitch of the guide rail 200 needs to be adjusted, the locking bolt 212 is tightened to lock the internally threaded sleeve 211 with the radial beam 208. In this way, when the first operating handwheel 210 is rotated, the vertical lead screw 209 drives the radial beam 208 to move in the vertical direction through the internally threaded sleeve 211, and the radial beam 208 drives the upper end of the guide rail 200 to move. When it is necessary to adjust the guide rail 200 so that it rotates a certain angle along the axis of the electrode boiler 100, first loosen the locking bolt 212 so that the internal threaded sleeve 211 and the radial beam 208 are in a rotationally connected state, and then manually drive the guide rail 200 to rotate a predetermined angle along the axis of the electrode boiler 100. After the rotation is completed, tighten the locking bolt 212.

[0035] As a preferred embodiment of the present invention, Figure 5-12As shown, the walking monitoring mechanism 300 includes a mounting base 301, a drive assembly 306, a medium supply system 308, two adjustment assemblies 310, and two monitoring assemblies 307. Two assembly ears 302 are constructed on the mounting base 301, and an assembly opening 309 is formed between the two assembly ears 302. The two assembly ears 302 are slidably connected to the guide rail 200 through the assembly opening 309. The drive assembly 306 of this embodiment is mounted on the mounting base 301 and is transmission-connected to the guide rail 200. The two monitoring assemblies 307 are connected to the two adjustment assemblies 310 in a one-to-one correspondence, and the two adjustment assemblies 310 are connected to the two assembly ears 302 in a one-to-one correspondence. The medium supply system 308 is mounted on the mounting base 301, and both monitoring assemblies 307 are connected to the medium supply system 308. The operating principle and advantages of this embodiment are as follows: A fixed edge 304 is constructed on the mounting base 301, a battery is mounted on the fixed edge 304, and a processor is mounted on the mounting base 301. The battery, drive assembly 306, and two monitoring assemblies 307 are all connected to the processor. This embodiment controls the operation of the drive assembly 306, causing it to drive the mounting base 301 along the guide rail 200. During the guided movement of the mounting base 301 along the guide rail 200, it drives the medium supply system 308 and the two monitoring assemblies 307, allowing the two monitoring assemblies 307 to continuously monitor the outer peripheral wall of the electrode boiler 100. Furthermore, the use of two monitoring assemblies 307 for monitoring improves monitoring accuracy, and the movement trajectories of the two monitoring assemblies 307 are close to or partially overlap, thereby improving the efficiency and comprehensiveness of monitoring. During the monitoring process, the medium supply system 308 supplies the medium used for monitoring to the two monitoring components 307. The two monitoring components 307 apply the medium to the outer wall of the electrode boiler 100, so that the monitoring end contacts the outer wall of the electrode boiler 100 through the medium, thereby making the monitoring data more accurate.

[0036] As a preferred embodiment of the present invention, Figure 8As shown, the drive assembly 306 includes a drive motor 3061 and a driving gear 3062.

A connecting lug 305 is configured on the mounting base 301, and the connecting shaft is rotatably connected to the connecting lug 305. In this embodiment, a mounting groove 202 is configured on the end surface of the guide rail 200 near the driving gear 3062. The mounting groove 202 extends to both ends of the guide rail 200 along the extension direction of the guide rail 200. A plurality of transmission teeth are configured within the mounting groove 202. These transmission teeth are spaced apart along the extension direction of the guide rail 200 and form a spiral rack-like structure (a rack-like structure) within the mounting groove 202. The driving gear 3062 meshes with this spiral rack-like structure. The working principle and advantages of this embodiment are as follows: this embodiment controls the operation of the driving motor 3061 to drive the driving gear 3062 to rotate. Since the driving gear 3062 is engaged with the spiral rack structure, the driving gear 3062 moves along the guide rail 200, thereby driving the mounting base 301 and other components on the mounting base 301 to move together.

[0037] As a preferred embodiment of the present invention, Figure 9-12As shown, the monitoring assembly 307 includes a columnar connector 3071, a mounting tube 3072, a monitoring probe 3078, and two medium smearing bodies 3077. The columnar connector 3071 is connected to the adjustment assembly 310. The columnar connector 3071 extends radially along the electrode boiler 100. The mounting tube 3072 is mounted on one end of the columnar connector 3071 close to the outer peripheral wall of the electrode boiler 100. The monitoring probe 3078 is coaxially mounted in the mounting tube 3072. The wire 312 of the monitoring probe 3078 extends through the columnar connector 3071 and is connected to the processor. The inner cavity of the mounting tube 3072 is divided into a first chamber 3074 and a second chamber 3075 by a vertical partition 3073. The first chamber 3074 and the second chamber 3075 are spaced apart along the movement direction of the mounting seat 301. 5 are respectively installed with connecting springs 3076, and two medium smear bodies 3077 are movably assembled in the first chamber 3074 and the second chamber 3075, respectively. The two medium smear bodies 3077 fill the open ends of the first chamber 3074 and the second chamber 3075, respectively. One end of each medium smear body 3077 extends out of the corresponding first chamber 3074 or second chamber 3075, and each medium smear body 3077 contacts the surface of the electrode boiler 100. The other end of the medium smear body 3077 is connected to the corresponding connecting spring 3076. The first chamber 3074 and the second chamber 3075 are both connected to the medium supply system 308, and the monitoring probe 3078 is located between the two medium smear bodies 3077. The end of the medium smear body 3077 that extends out of the mounting tube 3072 is made of a soft material and is covered with holes, similar to a sponge structure. The end of the medium smear body 3077 that extends into the mounting tube 3072 is made of a hard material and is covered with liquid guide holes. The operating principle and advantages of this embodiment are as follows: In this embodiment, the medium is supplied to the first chamber 3074 and the second chamber 3075 via the medium supply system 308. The medium penetrates into the soft material portion of the medium smear body 3077 through the medium smear body 3077. During the movement of the mounting seat 301 along the guide rail 200, the medium smear body 3077 is in constant contact with the outer wall of the electrode boiler 100, thereby applying the medium to the outer wall of the electrode boiler 100. The monitoring probe 3078 contacts the outer wall of the electrode boiler 100 through the medium, thereby achieving the purpose of accurately monitoring the outer wall of the electrode boiler 100. Moreover, the mounting seat 301 can be driven forward or reversely on the guide rail 200 according to the driving component 306, and the medium can be synchronously controlled to enter the first chamber 3074 or the second chamber 3075 (there is no need to synchronously supply the medium to the first chamber 3074 and the second chamber 3075), so that the medium smearing body 3077 located in front of the monitoring probe 3078 smears the medium on the outer wall of the electrode boiler 100, and then the corrosion monitoring operation is performed.In this embodiment, due to the provision of the connecting spring 3076 , the medium smearing body 3077 is always in elastic contact with the outer peripheral wall of the electrode boiler 100 , ensuring that the medium is continuously smeared on the outer peripheral wall of the electrode boiler 100 .

The adjustment screw 3104 of this embodiment is threadedly connected to the adapter ear 3101 and extends along the length of the assembly hole 3102. One end of the adjustment screw 3104 is rotatably connected to the connecting block 3103, and the other end of the adjustment screw 3104 is mounted with a second operating handwheel 3105. In this embodiment, the columnar connector 3071 is movably connected to the connecting block 3103. A telescopic spring 311 is sheathed around the columnar connector 3071, with its ends respectively connected to the connecting block 3103 and the mounting cylinder 3072. The operating principle and advantages of this embodiment are as follows: Under the action of the telescopic spring 311, the columnar connector 3071 elastically drives the mounting cylinder 3072 toward the electrode boiler 100, thereby ensuring that the monitoring probe 3078 and the medium applicator 3077 are always in elastic contact with the outer peripheral wall of the electrode boiler 100. In this embodiment, by rotating the second operating handwheel 3105, it causes the adjustment screw 3104 to rotate. In this way, the adjustment screw 3104 drives the connecting block 3103 to move along the length of the assembly hole 3102, so that the connecting block 3103 drives the columnar connector 3071 and other components connected to the columnar connector 3071 to move synchronously, thereby adjusting the position of the monitoring probe 3078 and the medium applicator 3077, thereby improving the comprehensiveness of monitoring the peripheral wall of the electrode boiler 100.
