Description

Technical Field

[0001] The invention relates to the technical field of blank smelting, and in particular to a brass plate strip blank smelting device and a smelting method. Background Art

[0002] Waterstop copper sheet is suitable for foundation waterstop and dam waterstop of advanced hydraulic structures. It has good corrosion resistance, high compressive strength and good deformability. Brass strip is one of the commonly used raw materials for producing waterstop copper sheet. Brass strip is an alloy of copper and zinc. Brass strip needs to be melted before use so that it can be used plastically in the later stage.

[0003] When the existing brass strip blank smelting equipment is used, first, people add the brass strip blank into the smelting furnace, and then smelt the brass strip blank through the smelting furnace. Since the blank will accumulate at the bottom of the tank after melting, the blank can be added again at this time until a set amount of molten raw materials are accumulated in the tank. After smelting, people use tools to dump the smelting furnace and guide the molten liquid in the smelting furnace into the container prepared by people, so as to achieve the effect of smelting the brass strip blank. Since a large amount of smoke and dust is generated in the furnace body after heating, it is very easy to spray out through the opening when adding raw materials and dumping output in the middle, affecting the health of workers and the air quality in the factory. At the same time, a large amount of smoke and dust will affect the workers' sight, which is not conducive to the feeding and discharging operations, and reduces the production efficiency.

DETAILED DESCRIPTION

The feed hopper 6 and the collecting hopper 7 are respectively located on both sides of the smelting tank 2. An output groove 8 connected to the collecting hopper 7 is provided on the side of the fixing ring 3. The conveying mechanism 5 is used to change the rotation direction of the rotating column 4, so that the upper end opening of the smelting tank 2 is connected with the feed hopper 6 to complete the feeding. During the material discharging operation, the smelting pot 2 can be connected with the output trough 8 to complete the material discharging operation. The exhaust mechanism 9 includes a connecting frame 10 installed on both sides of the fixing ring 3. An exhaust hood 11 is fixedly connected between the two sets of connecting frames 10. The inner wall of the exhaust hood 11 can slide and fit with the outer wall of the upper end of the feed hopper 6. An exhaust member 12 is provided in the output trough 8 for exhausting the set position on the upper side of the smelting pot 2 during material discharging. The exhaust mechanism 9 is used to preferentially control the exhaust hood 11 to deflect when the conveying mechanism 5 is running, and control the smelting pot 2 to rotate after the exhaust hood 11 is deflected to the set position, so that during the material feeding and discharging operations, the smoke and dust will not diffuse outward through the position of the feed hopper 6 and the output trough 8.

[0032] See also Figure 1-Figure 10 The smelting method of a brass plate and strip blank smelting equipment shown in the figure comprises the following steps:

[0033] S1. Add the brass sheet to be added into the feed hopper 6, start the conveying mechanism 5 and the exhaust mechanism 9, rotate the exhaust hood 11 to the upper side of the feed hopper 6 first, close the feed hopper 6, and then drive the smelting tank 2 to rotate to a position connected to the bottom end of the feed hopper 6, so that the blank can be input into the smelting tank 2 while avoiding the diffusion of smoke and dust;

[0034] S2. After the feeding is completed, the conveying mechanism 5 drives the smelting pot 2 to rotate in the opposite direction. At this time, the exhaust hood 11 still sucks the smoke and dust remaining in the feed hopper 6. When the smelting pot 2 rotates to a vertical state, the smelting pot 2 stops rotating to perform the melting operation. Thereafter, the exhaust hood 11 rotates in the opposite direction to reset and open the opening of the feed hopper 6;

[0035] S3. During discharging, the conveying mechanism 5 and the exhaust mechanism 9 are in operation, and the exhaust hood 11 is rotated to the side of the output trough 8 first, and then the smelting pot 2 is linked to rotate and dump. During the dumping process, the exhaust member 12 is linked to operate, and the smoke and dust on the upper side are continuously sucked to prevent the smoke and dust from spreading. After the discharging is completed, the smelting pot 2 is rotated to a vertical state and reset, and then the exhaust hood 11 is rotated and reset.

[0036] In this embodiment, the brass plate and strip blank to be added is added to the feed hopper 6, the conveying mechanism 5 and the exhaust mechanism 9 are started, and the exhaust hood 11 is preferentially rotated to the upper side of the feed hopper 6 to close the feed hopper 6, and then the smelting pot 2 is driven to rotate to a position connected to the bottom end of the feed hopper 6, so that the blank can be input into the smelting pot 2 while avoiding the diffusion of smoke and dust. After the feeding is completed, the conveying mechanism 5 drives the smelting pot 2 to rotate in the opposite direction. At this time, the exhaust hood 11 still sucks the smoke and dust remaining in the feed hopper 6. When the smelting pot 2 rotates to a vertical state, the smelting pot 2 stops. The melting operation is carried out by rotating, after which the exhaust hood 11 is reversely rotated and reset, the opening of the feed hopper 6 is opened, the conveying mechanism 5 and the exhaust mechanism 9 are operated, and the exhaust hood 11 is preferentially rotated to the side of the output slot 8, and then the smelting pot 2 is linked to rotate and dump, and the exhaust member 12 is linked to operate during the dumping process, and the smoke and dust on the upper side are continuously sucked to prevent the smoke and dust from spreading. After the discharge is completed, the smelting pot 2 is rotated to a vertical state and reset, and then the exhaust hood 11 is rotated and reset. The device is efficient and convenient to operate, improves the smelting and conveying efficiency of the blank, and is safer and more environmentally friendly during use. Example 2

[0037] See also Figure 1-Figure 7 Embodiment 2 is described. This embodiment further describes embodiment 1. The exhaust mechanism 9 shown in the figure also includes two groups of support frames 13 fixedly mounted on the base 1. Both sides of the rotating column 4 are coaxially fixedly connected with a driving shaft 14 rotatably connected to the support frame 13. The side of the support frame 13 is rotatably connected with a rotating ring 15 and a driving disk 16. The connecting frame 10 is fixedly connected to the outer wall of the rotating ring 15. The driving shaft 14 is provided with a transmission member 17 for driving the driving shaft 14 to rotate through the driving disk 16 after the rotating ring 15 rotates to a set angle.

[0038] See also Figure 1-Figure 7 The transmission member 17 shown in the figure includes multiple groups of first tension springs 18 fixedly installed on the outer wall of the driving disk 16, one end of the first tension spring 18 away from the driving disk 16 is fixedly connected to the inner wall of the rotating ring 15, a first slide groove 19 is provided on the driving disk 16, a first clamping block 20 is slidably connected in the first slide groove 19, one end of the first clamping block 20 is fixedly connected to a second tension spring 21 fixedly connected to the first slide groove 19, two groups of plugging grooves 22 that can be plugged into the first clamping block 20 are provided on the outer wall of the driving shaft 14, a driving member 23 for driving the driving disk 16 to rotate is provided on the base 1, and a control member 24 for controlling the plugging state of the first clamping block 20 and the plugging groove 22 according to the position of the first clamping block 20 is provided on the support frame 13.

[0039] See also Figure 6-Figure 7The control member 24 shown in the figure includes a driving block 25 fixedly mounted on the first clamping block 20, and a first arc groove 26 and a second arc groove 27 which can be slidably connected to the outer wall of the driving block 25 are provided on the support frame 13, and the two ends of the first arc groove 26 are respectively connected to the two ends of the second arc groove 27, and the radius of the first arc groove 26 is greater than the radius of the second arc groove 27. Two groups of blocks 44 for limiting the position of the connecting frame 10 are fixedly connected to the support frame 13.

[0040] See also Figure 2-Figure 7 The driving member 23 shown in the figure includes a driving motor 39 fixedly mounted on the base 1, and the driving motor 39 model is preferably Y80M1-2. The output end of the driving motor 39 is coaxially fixedly connected with a rotating shaft 40, and two sets of driving wheels 41 are coaxially fixedly connected to the rotating shaft 40. A driven wheel 42 is coaxially fixedly connected to the side of the driving disk 16, and the outer wall of the driving wheel 41 is transmission-connected with a transmission belt 43 transmission-connected to the driven wheel 42.

[0041] In this embodiment, starting the driving motor 39 drives the rotating shaft 40 and the driving wheel 41 to rotate, so that the driven wheel 42 drives the driving disk 16 to rotate. When feeding, the driving disk 16 rotates counterclockwise, driving the first tension spring 18 to pull the rotating ring 15 to rotate, and the connecting frame 10 drives the exhaust hood 11 to rotate to the upper side of the feeding hopper 6. At this time, the connecting frame 10 conflicts with the stopper 44 on one side, and the connecting frame 10 cannot continue to rotate. The driving block 25 gradually slides from the first arc groove 26 into the second arc groove. The arc groove 27 makes the first clamping block 20 gradually slide inward and be inserted into the plug-in groove 22. After that, the driving disc 16 continues to rotate to drive the driving shaft 14 and the rotating column 4 to rotate together. The first tension spring 18 is gradually stretched until the smelting pot 2 rotates to a state connected with the bottom of the feed hopper 6. The blanks in the feed hopper 6 can be discharged into the smelting pot 2 to complete the feeding operation. At this time, the smelting pot 2 is in an inclined state. During the feeding process, the raw materials slide down from the inner wall to reduce impact damage and splashing of the molten liquid.

[0042] When the feeding is completed, the driving motor 39 drives the driving disk 16 to rotate clockwise, which can preferentially drive the driving shaft 14 and the rotating column 4 to rotate and reset, and the smelting pot 2 rotates to a vertical state, and the top end is closed against the inner wall of the fixing ring 3, and the driving block 25 slides from the second arc groove 27 into the first arc groove 26, releasing the linkage with the driving shaft 14, and the first tension spring 18 is gradually pulled back, and then the rotating ring 15 and the exhaust hood 11 can be driven to rotate and reset, and the smelting operation is carried out.

[0043] Similarly, when discharging is required, the driving disc 16 rotates clockwise, driving the rotating ring 15 to rotate clockwise to the position of the block 44 on the other side. At this time, the exhaust hood 11 conflicts with the upper side of the collecting bucket 7, and then the first block 20 is inserted into the plug-in slot 22 to drive the driving shaft 14 to rotate clockwise, and the smelting pot 2 gradually tilts, and the molten blank inside is poured into the collecting bucket 7 through the output slot 8. At this time, the surrounding smoke and dust will be sucked out by the exhaust hood 11 to reduce the diffusion of smoke and dust. After the discharging is completed, the driving motor 39 drives the rotating ring 15 to rotate in the opposite direction and reset, and then the rotating column 4 and the smelting pot 2 are linked to rotate and reset. Example 3

[0044] See also Figure 1-Figure 10 Embodiment 3 is described. This embodiment further describes embodiment 1. The exhaust component 12 shown in the figure includes a fixed plate 28 fixedly mounted on the support frame 13. The outer wall of the fixed plate 28 is fixedly connected to a clockwork spring 29. Two groups of circular rings 30 are rotatably connected to the fixed ring 3. The outer end of the clockwork spring 29 is fixedly connected to the inner wall of the circular ring 30. The side of the circular ring 30 is coaxially fixedly connected to a mounting ring 31. An exhaust fan 32 is fixedly connected between the two groups of mounting rings 31. An adjusting component 33 for controlling the rotation angle of the exhaust fan 32 is provided on the rotating column 4.

[0045] See also Figure 8-Figure 10 The adjusting member 33 shown in the figure includes two groups of second clamping blocks 34 installed on the rotating column 4, and a second sliding groove 35 slidably connected to the second clamping block 34 is provided on the rotating column 4. An elastic member 36 fixedly connected to the second sliding groove 35 is fixedly connected to one end of the second clamping block 34. A triangular groove 37 and an oblique tooth groove 38 capable of being engaged with the second clamping block 34 are provided on the mounting ring 31. The side walls of the triangular groove 37 are all sloped surfaces, and the side of the oblique tooth groove 38 close to the exhaust fan 32 is a vertical surface, and the side away from the exhaust fan 32 is an inclined surface.

[0046] In this embodiment, when the rotating column 4 rotates counterclockwise, the second block 34 is initially limited by the triangular groove 37 to prevent the driving shaft 14 from being driven to rotate by friction until the first block 20 is inserted into the plug-in groove 22, and the tip of the second block 34 gradually slides out of the triangular groove 37, so that the smelting pot 2 rotates to feed the material. Conversely, when resetting, the second block 34 will initially limit the rotating column 4 after being inserted into the triangular groove 37, so as to keep the smelting pot 2 fixed in a vertical state.

[0047] It is worth noting that: when the rotating column 4 rotates clockwise, the second clamping block 34 is first limited by the triangular groove 37 until the first clamping block 20 drives the driving shaft 14 to rotate. At this time, the second clamping block 34 slides out of the triangular groove 37 and is engaged with the oblique tooth groove 38 after rotating to the set position. At this time, the position of the exhaust fan 32 is slightly higher than the liquid level of the molten blank in the smelting pot 2, and the smoke and dust discharged from the upper side can be directly sucked away. Then, as the smelting pot 2 continues to tilt, the second clamping block 34 drives the oblique tooth groove 38 to make the ring 30 rotate, the exhaust fan 32 rotates synchronously, and the spring spring 29 is compressed. After the discharge is completed, the smelting pot 2 rotates in the opposite direction to reset, and the spring spring 29 drives the ring 30 to reset the exhaust fan 32 in the opposite direction until the exhaust fan 32 reaches the top of the output groove 8 and is fixed. The second clamping block 34 gradually slides along the inclined surface from the oblique tooth groove 38, and is limited again after reaching the position of the triangular groove 37, and the driving disk 16 drives the exhaust hood 11 to rotate and reset.
