Description

Technical Field

[0001] This utility model relates to the field of water temperature monitoring technology, and in particular to a blast furnace cooling wall water temperature monitoring device. Background Technology

[0002] The water temperature difference of the blast furnace cooling wall can reflect the stability of the blast furnace airflow, the stability of the slag skin on the wall, the heat loss of the blast furnace, and the changes in the upper part of the blast furnace. This allows for a comprehensive judgment of the stability of the blast furnace condition and the energy consumption status. At the same time, by referring to the changes in the water temperature difference, load adjustment and airflow adjustment can be carried out in production.

[0003] In existing technologies, temperature measurement structures are directly installed on the pipeline via flanges. Under prolonged water flow impact, the temperature probes of the monitoring device are easily damaged. When repairing or replacing them, it is necessary to disconnect the water pipe valve to completely stop the water flow, and then disassemble the entire mounting flange structure for repair or maintenance, making the repair process very inconvenient.

[0004] Therefore, we propose a blast furnace cooling wall water temperature monitoring device to solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a blast furnace cooling wall water temperature monitoring device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a blast furnace cooling wall water temperature monitoring device, comprising a tube ring, a temperature probe, and a sphere. The tube ring is respectively provided with a positioning seat and a base. The base is provided with a sleeve, and the bottom end of the sleeve is provided with a spherical sleeve. The sphere is rotatably disposed within the spherical sleeve. The sphere is provided with a shaft, which passes through the spherical sleeve and is rotatably disposed on the positioning seat. The end of the shaft is provided with a positioning component. The temperature probe is inserted and positioned on the sleeve through the base, and the bottom end of the temperature probe passes through the sphere.

[0007] Preferably, the upper end of the temperature probe is provided with a screw seat, the screw seat and the base are in a threaded engagement state, and the top end of the temperature probe is provided with a connector.

[0008] Preferably, the sphere has a vertically formed insertion hole adapted to the temperature probe, the temperature probe passes through the insertion hole, and a sealing ring is provided between the inner wall of the insertion hole and the outer wall of the temperature probe.

[0009] Preferably, the inner wall of the ball sleeve is provided with a washer, and the outer wall of the ball presses against the inner wall of the washer.

[0010] Preferably, the positioning component consists of a spring, a square head, a square groove, and a column block. The square groove is formed inside the shaft, the square end of the column block is slidably disposed in the square groove, and the square head is disposed at the other end of the column block.

[0011] Preferably, the spring is sleeved on the column block, one end of the spring abuts against the square groove, the other end of the spring abuts against the square end of the column block, and the original length of the spring is greater than the depth of the square groove.

[0012] Preferably, the positioning seat has a square opening that matches the square head, and the square head is inserted into the square opening.

[0013] Preferably, flanges are symmetrically provided at both ends of the tube ring, and mounting holes are provided at equal intervals on the flanges.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In use, the blast furnace cooling wall water temperature monitoring device of this utility model is installed on the pipeline of the blast furnace cooling wall through a flange. The connector of the temperature probe is connected to an external computer through a data cable to display data. The bottom end of the temperature probe detects the temperature of the water flowing through the pipe ring.

[0016] When the temperature probe is damaged by prolonged water flow, the rotatable joint drives the screw seat to rotate. Through the threaded engagement between the screw seat and the base, the temperature probe moves upward away from the ball.

[0017] After the temperature probe detaches from the sphere, the operator pulls the square head outward, causing it to extend the column from the shaft. At this point, the spring is compressed and deforms. Once the square head is detached from the positioning seat, it is manually rotated, causing the shaft to rotate and the sphere to rotate within the sleeve, turning the insertion hole to a horizontal position. This closes the passage within the sleeve, preventing water from entering the casing. The square head is then released, and it returns to its original position under the spring force. Through the cooperation of the aforementioned positioning components, the shaft can be prevented from spinning.

[0018] With the cooperation of the above structures, the disassembly of the temperature probe can be completed, thereby facilitating the inspection or maintenance of the temperature probe.

[0019] This invention allows for the disassembly of temperature probes without completely shutting off the water supply to the pipeline, thus improving the ease of maintenance for temperature monitoring devices. Attached Figure Description

[0027] 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.

[0028] Example 1

[0029] like Figures 1-5 As shown, the present invention proposes a blast furnace cooling wall water temperature monitoring device, including a tube ring 4, a temperature probe 10, and a ball 13. The tube ring 4 is provided with a positioning seat 3 and a base 5. The base 5 is provided with a sleeve 7. The bottom end of the sleeve 7 is provided with a ball sleeve 8. The ball 13 is rotatably disposed inside the ball sleeve 8. The ball 13 is provided with a shaft 9. The shaft 9 passes through the ball sleeve 8 and is rotatably disposed on the positioning seat 3. The end of the shaft 9 is provided with a positioning component. The temperature probe 10 is inserted and positioned on the sleeve 7 through the base 5. The bottom end of the temperature probe 10 passes through the ball 13.

[0030] Based on Example 1:

[0031] During use, the blast furnace cooling wall water temperature monitoring device of this utility model is installed on the pipeline of the blast furnace cooling wall through flange 1. The connector 6 of the temperature probe 10 is connected to an external computer through a data cable to display data. The bottom end of the temperature probe 10 detects the temperature of the water flowing through the pipe ring 4.

[0032] When the temperature probe 10 is damaged by prolonged water flow, the rotatable joint 6 drives the screw seat 11 to rotate. Through the threaded engagement between the screw seat 11 and the base 5, the temperature probe 10 moves upward away from the ball 13.

[0033] At this time, after the temperature probe 10 is separated from the ball 13, the person pulls the square head 16 outward, so that the square head 16 drives the column block 18 to extend out of the shaft 9. At this time, the spring 15 is deformed by pressure. When the square head 16 is separated from the positioning seat 3, the square head 16 is manually rotated, so that the square head 16 drives the shaft 9 to rotate, thereby causing the ball 13 to rotate inside the ball sleeve 8 and rotate the insertion hole 12 to the horizontal direction, thereby closing the passage inside the ball sleeve 8 and preventing water from entering the sleeve 7. At this time, the square head 16 is released, and the square head 16 returns to its original position under the elastic force of the spring 15. Through the cooperation of the above positioning components, the shaft 9 can be prevented from spinning.

[0034] With the cooperation of the above structures, the disassembly of the temperature probe 10 can be completed, thereby facilitating the inspection or maintenance of the temperature probe 10.

[0035] Example 2

[0036] like Figures 1-5 As shown, the blast furnace cooling wall water temperature monitoring device proposed in this utility model, compared with the first embodiment, further includes: a screw seat 11 at the upper end of the temperature probe 10, the screw seat 11 and the base 5 being in a threaded engagement state, a connector 6 at the top of the temperature probe 10, the rotatable connector 6 driving the screw seat 11 to rotate, and the disassembly and assembly of the temperature probe 10 being completed through the threaded engagement relationship between the screw seat 11 and the base 5.

[0037] The ball 13 has a vertically protruding insertion hole 12 that is compatible with the temperature probe 10. The temperature probe 10 passes through the insertion hole 12, and a sealing ring is provided between the inner wall of the insertion hole 12 and the outer wall of the temperature probe 10. The inner wall of the ball sleeve 8 is provided with a gasket 14, and the outer wall of the ball 13 presses against the inner wall of the gasket 14. Through the cooperation of the above structures, the sealing performance at the contact position of the structural surface can be ensured.

[0038] The positioning assembly consists of a spring 15, a square head 16, a square groove 17, and a column block 18. The square groove 17 is formed inside the shaft 9. The square end of the column block 18 is slidably disposed within the square groove 17. The square head 16 is disposed at the other end of the column block 18. The spring 15 is sleeved on the column block 18, with one end of the spring 15 abutting against the square groove 17 and the other end abutting against the square end of the column block 18. The original length of the spring 15 is greater than the depth of the square groove 17. The positioning seat 3 has a square opening adapted to the square head 16, and the square head 16 is inserted into the square opening. After the probe 10 detaches from the ball 13, the operator pulls the square head 16 outward, causing the square head 16 to drive the column block 18 to extend out of the shaft 9. At this time, the spring 15 is deformed by pressure. After the square head 16 detaches from the positioning seat 3, the square head 16 is manually rotated, causing the square head 16 to drive the shaft 9 to rotate, thereby causing the ball 13 to rotate inside the ball sleeve 8 and rotate the insertion hole 12 to the horizontal direction, thereby closing the passage inside the ball sleeve 8. By limiting the length of the spring 15, the square head 16 is released, and the square head 16 returns to its original position under the elastic force of the spring 15.

[0039] Flanges 1 are symmetrically provided at both ends of the pipe ring 4. Mounting holes 2 are equidistantly provided on the flanges 1. The monitoring structure is installed on the pipeline of the blast furnace cooling wall through the flanges 1.
