Description

Technical Field

[0001] This utility model relates to the field of crude copper smelting equipment, and specifically discloses a split-type feeding port clamping device for a side-blown furnace. Background Technology

[0002] The side-blown furnace charging system consists of a furnace cover charging hole, a copper water jacket at the charging inlet, a clamping device, and a charging hopper. In production practice, it has been found that due to the continuous wear and tear on the copper water jacket at the charging inlet caused by the copper concentrate and quartz fed into the furnace, the jacket cannot last for a normal furnace cycle. It corrodes and leaks after approximately 10 months of use, posing a significant safety hazard when cooling water enters the furnace, necessitating timely replacement.

[0003] Due to the furnace's structural design, the area above the charging port includes a fume hood, burner pipes, and a moving trolley platform track, resulting in limited space for replacement. Furthermore, the crane's extreme position cannot reach the lifting location, necessitating lifting via a chain hoist, which significantly complicates the process. Additionally, the clamping device is an integrated cover, with only a 5mm gap between the charging port copper water jacket and the clamping device. After nearly a year of use, the two have become tightly pressed together, making disassembly impossible. The numerous mounting holes and the difficulty and time-consuming bolt removal further complicate the replacement process. This extended replacement time leads to prolonged shutdowns of the side-blown furnace, increasing production costs and raising the risk of furnace failure due to prolonged shutdowns of both side-blown and top-blown furnaces. Therefore, a separate charging port clamping device for side-blown furnaces is needed to address this issue. Utility Model Content

[0004] This utility model proposes a split-type feeding port clamping device for a side-blown furnace. By changing the one-piece cylindrical pressure cover to two semi-cylindrical split pressure covers, the number of fixing bolts is reduced while ensuring the fastening requirements are met, thus improving the replacement efficiency.

[0005] This utility model is implemented as follows: a split-type feeding port clamping device for a side-blown furnace includes a feeding port copper water jacket, the outer wall of which is provided with a furnace cover feeding port short circuit, and a clamping mechanism is provided above the feeding port copper water jacket.

[0006] The clamping mechanism consists of a first pressure cover, a second pressure cover, and four fastening mounting holes. The first pressure cover and the second pressure cover are symmetrically installed on the outer wall of the top of the copper water jacket at the feed port. The four fastening mounting holes are respectively opened on the first pressure cover and the second pressure cover, with two holes on each of the first pressure cover and the second pressure cover.

[0007] A connecting flange is fixedly connected to the upper end face of the furnace cover discharge port, and four bolt holes corresponding to the fastening installation holes are opened through the connecting flange.

[0008] In a preferred embodiment of the split-type feed port clamping device for a side-blown furnace according to this utility model, the connecting flange is detachably connected to the first and second pressure plates via connecting bolts.

[0009] As a preferred embodiment of the side-blown furnace split-type feeding port clamping device of this utility model, the outer wall of the feeding port copper water jacket is connected to two copper water jacket inlet and outlet pipes, and the outer walls of the first and second pressure covers are provided with reserved holes for the copper water jacket inlet and outlet pipes to connect with external pipes.

[0010] As a preferred embodiment of the split-type feeding port clamping device for a side-blown furnace according to this utility model, both the first and second pressure covers are semi-circular in shape.

[0011] In a preferred embodiment of the split-type discharge port clamping device for a side-blown furnace according to this utility model, the bottom ends of the first and second pressure covers are in contact with the connecting flange.

[0012] The beneficial effects of this utility model are:

[0013] By changing the one-piece cylindrical pressure cover to two semi-cylindrical split pressure covers based on the original split-type feeding port clamping device of the side-blown furnace, and reducing the number of fastening installation holes from 8 to 4, with two holes distributed on the first pressure cover and two holes on the second pressure cover, the number of fixing bolts is reduced while ensuring the fastening requirements are met, thus improving the replacement efficiency.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0020] Please see Figure 1-3 A split-type feeding port clamping device for a side-blown furnace includes a feeding port copper water jacket 3, a furnace cover feeding port short circuit 5 is provided on the outer wall of the feeding port copper water jacket 3, and a clamping mechanism is provided above the feeding port copper water jacket 3.

[0021] The clamping mechanism consists of a first pressure cover 1, a second pressure cover 2 and four fastening mounting holes 6. The first pressure cover 1 and the second pressure cover 2 are symmetrically installed on the outer wall of the top of the copper water jacket 3 at the feed port. The four fastening mounting holes 6 are respectively opened on the first pressure cover 1 and the second pressure cover 2, and two are distributed on each of the first pressure cover 1 and the second pressure cover 2.

[0022] A connecting flange 501 is fixedly connected to the upper end face of the furnace cover discharge port short joint 5. Four bolt holes corresponding to the fastening installation holes 6 are opened through the connecting flange 501.

[0023] In this embodiment, the clamping device is changed from an integrated cylindrical cover to two semi-cylindrical separate covers installed symmetrically. The number of connecting bolts between the first cover 1 and the second cover 2 and the short-circuit 5 at the furnace cover discharge port is reduced from 8 to 2 for each semi-cylindrical cover, for a total of 4 bolts. While ensuring the tightness requirements, the number of fixing bolts is reduced, improving the replacement efficiency. The bolt connection between the first cover 1 and the second cover 2 and the short-circuit 5 at the furnace cover discharge port achieves the clamping function, thereby ensuring the clamping effect while improving the ease of disassembly and assembly of the clamping device. This effectively solves the problem of difficult disassembly and assembly of the clamping device and the short-circuit 5 at the furnace cover discharge port. Furthermore, the separate disassembly and assembly greatly improves the replacement efficiency of the water jacket, saving more than one-third of the replacement time. This eliminates the safety risks caused by water jacket leakage and reduces the production costs of long-term furnace shutdown and the risk of furnace failure caused by shutdown.

[0024] As a technical optimization of this utility model, the connecting flange 501 is detachably connected to the first pressure cover 1 and the second pressure cover 2 by connecting bolts.

[0025] In this embodiment, the connecting bolts facilitate the disassembly or fixing of the connecting flange 501, the first pressure cover 1, and the second pressure cover 2.

[0026] As a technical optimization of this utility model, the outer wall of the copper water jacket 3 at the discharge port is connected to two copper water jacket inlet and outlet pipes 4, and the outer walls of the first pressure cover 1 and the second pressure cover 2 are provided with reserved holes 7 for connecting the copper water jacket inlet and outlet pipes 4 with external pipes.

[0027] In this embodiment, water can smoothly enter the copper water jacket 3 at the feed port through the copper water jacket inlet and outlet pipe 4, and the copper water jacket inlet and outlet pipe 4 can smoothly pass through the reserved hole 7 to connect with the external pipe.

[0028] As a technical optimization of this utility model, both the first pressure cover 1 and the second pressure cover 2 are semi-circular in shape.

[0029] In this embodiment, by making both the first pressure cap 1 and the second pressure cap 2 semi-circular, the integrated cylindrical pressure cap is changed to two separate semi-cylindrical pressure caps, which ensures the clamping effect while improving the ease of disassembly and assembly of the clamping device.

[0030] As a technical optimization of this utility model, the bottom ends of the first pressure cover 1 and the second pressure cover 2 are in contact with the connecting flange 501.

[0031] In this embodiment: the bottom ends of the first pressure cap 1 and the second pressure cap 2 contact the connecting flange 501 to facilitate the connection of the first pressure cap 1 and the second pressure cap 2 to the connecting flange 501.

[0032] The working principle and usage process of this utility model are as follows: By changing the clamping device from an integrated cylindrical pressure cover to two semi-cylindrical split pressure covers installed symmetrically, the first pressure cover 1 and the second pressure cover 2 are brought into contact with the connecting flange 501 on the short connection 5 of the furnace cover discharge port. The first pressure cover 1 and the second pressure cover 2 are installed or removed from the short connection 5 of the furnace cover discharge port by bolts passing through the fastening mounting holes 6. In addition, by changing the original 8 connecting bolts to 2 for each semi-cylindrical pressure cover, a total of 4 bolts are used. While ensuring the fastening requirements, the number of fixing bolts is reduced, and the replacement efficiency is improved. The bolt connection between the first pressure cover 1 and the second pressure cover 2 and the short connection 5 of the furnace cover discharge port achieves the clamping function, thereby ensuring the clamping effect and improving the ease of disassembly and assembly of the clamping device. It effectively solves the problem of difficult disassembly and assembly of the clamping device and the short connection 5 of the furnace cover discharge port. Moreover, the split disassembly and assembly greatly improves the replacement efficiency of the water jacket, saving more than one-third of the replacement time. While eliminating the safety risks caused by water jacket leakage, it also reduces the production costs of long-term furnace shutdown and the risk of furnace failure caused by shutdown.
