Description

Technical Field

[0001] This utility model relates to the field of sealing gates, and in particular to a sealing gate device for a combustion furnace. Background Technology

[0002] A combustion furnace, also known as an electric arc combustion furnace or carbon-sulfur combustion furnace, or simply an electric arc furnace, is a device that uses a high-voltage, high-frequency oscillating circuit to generate a large instantaneous current to ignite the sample. The sample is then rapidly combusted under oxygen-rich conditions, and the resulting mixed gas is analyzed quantitatively and quickly through a chemical analysis process to determine the carbon and sulfur content in the sample.

[0003] Existing combustion furnaces mostly use rotating sealing gates, which are connected to the furnace shell via a hinged shaft. However, during the use of these sealing gates, on the one hand, prolonged high temperatures can cause slight deformation of the gate, easily affecting its sealing performance and thus impacting the service life of the combustion furnace. On the other hand, waste residue generated inside the combustion furnace tends to adhere to the side walls of the sealing gate, requiring the gate to be opened and cooled before cleaning, which is time-consuming and cumbersome. Therefore, improvements are needed. Utility Model Content

[0004] To address the cumbersome post-combustion cleaning process of sealing gates in related technologies, this invention provides a sealing gate device for combustion furnaces.

[0005] The sealing gate device for a combustion furnace provided by this utility model adopts the following technical solution:

[0006] A sealing gate device for a combustion furnace includes a positioning rod located on one side of the combustion furnace. A clearance block is provided on the side wall of the positioning rod, and a clearance groove is formed on the side wall of the clearance block. A clearance cylinder is provided in the clearance groove and is positioned towards the positioning rod. A connecting rod is provided at the output end of the clearance cylinder, and a sealing gate is connected to the end of the connecting rod away from the clearance cylinder. The sealing gate is used to seal the combustion furnace, and an abutment mechanism is provided on the side of the sealing gate away from the combustion furnace.

[0007] By adopting the above technical solution, after the combustion furnace sealing gate of this utility model has been used up, the operator directly drives the displacement cylinder, which drives the connecting rod to move away from the combustion furnace, thereby causing the sealing gate to move away from the gate opening of the combustion furnace. Since the overall cross-sectional area of ​​the sealing gate is larger than the opening area of ​​the combustion furnace gate, compared with the sealing furnace in related technologies, the sealing gate of this utility model cools down faster after combustion. Moreover, the rotatable displacement cylinder enables the rapid replacement of the spare gate, making it easier to clean.

[0008] Optionally, the abutting mechanism includes an abutting bracket, an abutting plate, an abutting rod, and a driving device. The abutting bracket is disposed on the side of the sealing gate away from the combustion furnace. The abutting rod is disposed on the abutting bracket. The abutting plate abuts against the side wall of the sealing gate away from the positioning rod. An abutting collar is disposed on the abutting bracket. The abutting rod is threadedly connected to the abutting collar. The abutting rod is connected to the side wall of the abutting plate away from the sealing gate. The driving device is used to control the rotation of the abutting rod.

[0009] By adopting the above technical solution, the sealing gate is abutted by the abutting device. Compared with the sealing gate being covered by a single displacement cylinder, the airtightness is higher, and the possibility of poor airtightness when the sealing gate seals the combustion furnace gate is reduced.

[0010] Optionally, the driving device includes a drive motor, a drive gear, and a meshing gear cylinder. The drive motor is mounted on the abutment bracket, the drive gear is mounted on the output end of the drive motor, and the meshing gear cylinder is sleeved on the side wall of the abutment rod. The drive gear and the meshing gear cylinder are meshed together.

[0011] By adopting the above technical solution, the operator can start the drive motor to drive the drive gear to rotate, which in turn causes the meshing gear cylinder to drive the abutment rod to rotate. This causes the abutment rod to rotate in the direction of the sealing gate within the abutment collar and abut against the side wall of the sealing gate, thereby increasing the airtightness of the sealing gate when sealing the combustion furnace gate opening.

[0012] Optionally, a secondary sealing sleeve is provided on the side wall of the sealing gate away from the abutment mechanism. After the sealing gate seals the combustion furnace, the secondary sealing sleeve fits against the side wall of the combustion furnace.

[0013] By adopting the above technical solution and through the structure of the secondary sealing shell, the airtightness between the sealing gate and the combustion furnace is further increased, making it difficult for heat in the combustion furnace to dissipate, and further increasing the heat preservation performance of the sealing gate.

[0014] Optionally, a sealing compound is provided on the open sidewall of the secondary sealing sleeve, and the sealing compound is in contact with the sidewall of the combustion furnace.

[0015] By adopting the above technical solution and through the structure of the sealing colloid, the sealing performance between the secondary sealing sleeve and the side wall of the combustion furnace is improved, further reducing the possibility of heat loss and saving energy.

[0016] Optionally, the secondary sealing sleeve is integrally formed with the sealing gate, and a pressure sensor is installed inside the secondary sealing sleeve.

[0017] By adopting the above technical solution, the secondary molding structure achieves higher airtightness, and by adding a pressure sensor, it is possible to monitor in real time whether the sealing gate is leaking.

[0018] Optionally, at least two relief slots are provided, and a plurality of relief slots are arranged along the circumference of the relief block.

[0019] By adopting the above technical solution, the structure of several clearance slots allows operators to directly replace the sealing gate by rotating the clearance block. The rotated-out sealing gate can be cooled and cleaned. At the same time, another sealing gate can still seal the combustion furnace, allowing the combustion furnace to maintain normal operation, increasing work efficiency, and improving the convenience of cleaning the combustion furnace sealing gate.

[0020] Optionally, each of the clearance slots is equipped with a clearance cylinder, and the connecting rod is detachably connected to the sealing gate via a flange.

[0021] By adopting the above technical solution, the detachable flange connection allows the operator to rotate the sealing gate out for replacement after deformation by rotating the clearance block, thus improving the convenience of the operator when replacing the sealing gate.

[0022] In summary, this utility model has at least one of the following beneficial effects:

[0023] 1. After the combustion furnace sealing gate of this utility model is used up, the operator directly drives the displacement cylinder, which moves the connecting rod away from the combustion furnace, thereby causing the sealing gate to move away from the gate opening of the combustion furnace. Since the overall cross-sectional area of ​​the sealing gate is larger than the opening area of ​​the combustion furnace, compared with the sealing furnace in related technologies, the sealing gate of this utility model cools down faster after combustion. Moreover, the rotatable displacement cylinder enables quick replacement of the spare gate, making it easier to clean.

[0024] 2. The structure of several clearance slots allows operators to directly replace the sealing gate by rotating the clearance block. The rotated-out sealing gate can be cooled and cleaned. At the same time, another sealing gate can still seal the combustion furnace, so that the combustion furnace can maintain normal operation, increase work efficiency, and improve the convenience of cleaning the combustion furnace sealing gate.

[0030] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0031] This utility model discloses a sealing gate device for a combustion furnace. (Refer to...) Figure 1 A sealing gate device for a combustion furnace is installed on one side of the combustion furnace opening. It includes a positioning bracket, which is vertically arranged. A positioning rod 1 is fixedly installed on the positioning bracket by bolts. A relief block 11 is rotatably connected to the side wall of the positioning rod 1 facing the combustion furnace via a rotating shaft. Two relief grooves 12 are opened circumferentially on the side wall of the relief block 11. A relief cylinder 13 is fixedly connected to the bottom wall of each relief groove 12 by bolts. A connecting rod 14 is fixedly connected to the output end of the relief cylinder 13. The moving direction of the connecting rod 14 and the output end of the relief cylinder 13 is vertically arranged. A sealing gate 15 for sealing the combustion furnace is detachably connected to the end of the connecting rod 14 away from the relief cylinder 13 via a flange. The structure of the pair of connecting rods 14 and sealing gate 15 allows the other sealing gate 15 to be cooled or cleaned outside the combustion furnace while one sealing gate 15 is sealing the opening of the combustion furnace. The detachable flange further facilitates the disassembly and replacement of the sealing gate 15 by the staff.

[0032] Reference Figure 1 and Figure 2A contact structure is provided on the side of the positioning rod 1 away from the combustion furnace. The contact mechanism 2 is used to further bring the sealing gate 15 closer to the combustion furnace. A sealing ring is provided at the opening of the combustion furnace. When the contact structure brings the sealing gate 15 closer to the combustion furnace, the sealing ring is compressed, thereby increasing the airtightness of the combustion furnace during combustion. The contact mechanism 2 includes a contact bracket 21, a contact plate 22, a contact rod 23, and a driving device 3. The contact bracket 21 is located on one side of the positioning bracket. A contact collar 24 is welded and fixed to the contact bracket 21. The contact rod 23 is inserted into the contact collar 24 and is threadedly connected to the contact collar 24. The contact plate 22 is rotatably connected to the end of the contact rod 23 near the sealing gate 15 via a rotating shaft.

[0033] Reference Figure 2 and Figure 3 The driving device 3 includes a drive motor 31, a drive gear 32, and a meshing gear cylinder 33. The drive motor 31 is mounted on the abutment bracket 21. The drive gear 32 is located at the output end of the drive motor 31. The meshing gear cylinder 33 is sleeved on the abutment rod 23, and the meshing gear cylinder 33 is located on the side of the abutment ring 24 away from the combustion furnace. When the drive motor 31 drives the drive gear 32 to rotate, the meshing gear cylinder 33 drives the abutment rod 23 to rotate, thereby causing the abutment rod 23 to rotate in the direction of the sealing gate 15 within the abutment ring 24, and abut against the side wall of the sealing gate 15, increasing the airtightness of the sealing gate 15 when sealing the combustion furnace gate opening.

[0034] Reference Figure 2 and Figure 4 A secondary sealing sleeve 4 is integrally formed on the side wall of the sealing gate 15 near the combustion furnace. The dimensions of the secondary sealing sleeve 4 are based on the dimensions of the outer side wall of the combustion furnace that needs to be sealed. The secondary sealing sleeve 4 has an opening on the side away from the sealing gate 15, and a sealing adhesive 41 is circumferentially glued to the opening. When the abutment plate 22 abuts the sealing gate 15 against the opening of the combustion furnace, the secondary sealing sleeve 4, along with the sealing adhesive 41, abuts against the outer shell of the combustion furnace. This further increases the heat insulation effect of the sealing gate 15, making it difficult for hot air inside the sealing gate 15 to escape. A pressure sensor 42 is also installed inside the secondary sealing sleeve 4 to monitor the pressure inside the secondary sealing sleeve 4, thereby monitoring the airtightness of the sealing gate 15 and the secondary sealing sleeve 4 in real time and reducing the possibility of hot air leakage.

[0035] The implementation principle of the sealing gate device for a combustion furnace according to this utility model embodiment is as follows: When the sealing gate 15 of this utility model is in use, the operator first rotates the clearance block 11 so that one sealing gate 15 faces the opening of the combustion furnace. Then, the clearance cylinder 13 is activated, causing the clearance cylinder 13 to move the sealing gate 15 to fit against the opening of the combustion furnace. At this time, the secondary sealing sleeve 4 fits against the side wall of the combustion furnace. Then, the drive motor 31 drives the drive gear 32 to rotate, and the drive gear 32 drives the meshing gear cylinder 33 to rotate, thereby driving the abutment rod 23 to move towards the sealing gate 15 within the abutment sleeve 24, so that the abutment plate 22 abuts against the sealing gate 15. The combustion furnace starts and begins normal operation.

[0036] After the combustion furnace finishes operation, the drive motor 31 drives the drive gear 32 to reverse, which in turn causes the abutment rod 23 to reverse within the abutment collar 24. This causes the abutment rod 23 to pull the abutment plate 22 away from the side wall of the abutment gate. Then, the release cylinder 13 drives the sealing gate 15 to move in the opposite direction. If the combustion furnace needs to be restarted, the release block 11 rotates, and the operator directly installs another sealing gate 15 on another connecting rod 14 through a flange. The combustion furnace is then sealed in the same way as described above. The sealing gate 15 used for the first time is removed from the opening of the combustion furnace, thus achieving cooling and cleaning of the sealing gate 15 used for the first time.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
