Description

Technical Field

[0001] The utility model relates to the technical field of furnace lining feeding.

[0002] Specifically, it relates to a furnace wall feeding machine. Background Art

[0003] In the technical field of furnace building and feeding, there are currently mainly two methods: "manual feeding" and "mechanical feeding". The current situations of these two methods are described as follows.

[0004] Manual feeding is the most primitive process. When feeding machines were not yet popular, many enterprises had no choice but to use this process. The method of this process is to use manual labor to carry, unpack and pour bag after bag of sand materials into the furnace. The dust pollution is serious, the labor intensity is very high, and the labor cost is very high. When the furnace body is relatively deep, the falling of sand materials is likely to cause particle segregation, affecting the furnace life.

[0005] Mechanical feeding: For existing mechanical feeding, such as in the Chinese utility model patent with the application number CN202110698031.9, the feeding machine is fixed on the crucible, the hopper is at the top of the feeding machine, and a screw conveyor is installed below the hopper. The screw conveyor sends the sand materials into the material pipe. The material pipe has a telescopic function and can freely expand and contract according to the depth of the material level. While rotating, the discharge port is close to the material level and outputs evenly, which solves problems such as dust pollution, particle segregation and excessive labor intensity. However, there are still some problems. ① Since the telescopic material pipe is a telescopic joint structure and the number of joints cannot be too many, the retracted material pipe has a certain length, resulting in too high a height of the equipment and increasing the feeding difficulty. ② Since the feeding pipe is made of hard metal material, the splashing sand and sand grains often jam the material pipe, causing difficulty in expansion and contraction.

[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0040] Embodiment: As Figure 1 - 20 shown, a furnace wall feeder includes a fixing system, a running system, a material pipe lifting system, and a feeding system. The fixing system is used to fix the whole machine on the crucible, the running system is responsible for the operation of the machine, the material pipe lifting system is used to control the lifting of the material pipe, and the feeding system is used for feeding.

[0041] As Figure 3 - 4As shown in the figure, the fixing system includes a fixing disk 1, a toothed disk 2 installed on the fixing disk 1, and a sliding clamp 4 that can stretch along the fixing disk 1. The toothed disk 2 is fixedly connected to the upper surface of the fixing disk 1 and is concentric with the fixing disk 1. An iron plate frame 3 is fixedly connected to the lower surface of the fixing disk 1. The sliding clamp 4 is arranged in cooperation with the iron plate frame 3 and can slide reciprocally along the iron plate frame 3. The iron plate frame 3 is arranged along the radial direction of the fixing disk 1, and correspondingly, the sliding clamp 4 is also arranged along the radial direction of the fixing disk 1. A sliding clamp rail 5 is installed along the inner lower edge of the iron plate frame 3, and the sliding clamp 4 moves along the sliding clamp rail 5. The sliding clamp 4 is connected to a telescopic motor 6 that drives its movement. The telescopic motor 6 is fixedly installed on the fixing disk 1 and drives the main transmission shaft to rotate. The main transmission shaft drives the gear shafts on four surfaces through universal joints. The sliding clamp 4 is installed on the sliding clamp rail 5 in the iron plate frame 3. The sliding clamp 4 is equipped with a first rack 7 that meshes with the gear 8 on the gear shaft. The telescopic and retraction of the sliding clamp 4 is realized by the forward and reverse rotation of the telescopic motor 6. Four brackets 9 are also installed at the bottom of the fixing disk 1 for use when the equipment is placed.

[0042] As Figure 5 shown in the figure, the operating system includes a turntable 10 installed on the fixing disk 1 and an operating motor 11 that drives the turntable 10 to rotate. In this embodiment, the turntable 10 is arranged above the fixing disk 1 and is connected to the fixing disk 1 through a bearing 12. The operating motor 11 is installed on the upper surface of the turntable 10. The output end of the operating motor 11 passes through the turntable 10 and is connected to a driving gear 13. The driving gear 13 is meshed with the toothed disk 2. When the operating motor 11 is started, it drives the rotation under the action of the driving gear 13 and the toothed disk 2. A slip ring frame 14 is arranged at the center of the turntable 10. The slip ring frame 14 serves as the main rotating shaft of the turntable 10 and is fixed under the turntable 10. It passes through the fixing disk 1 and is assembled with a tightening nut. The fixing disk 1 and the turntable 10 are connected by a thrust bearing. A conductive slip ring 15 is installed at the bottom end of the slip ring frame 14 to prevent the wires from getting tangled when the equipment rotates.

[0043] As Figure 6 shown in the figure, the feeding system includes a hopper 16, a screw conveyor 17, a material pipe 18, and a frame 19 arranged on the turntable 10. The bottom of the screw conveyor 17 is fixedly connected to the turntable 10, the discharge port is connected to the material pipe 18, and the top feed port is fixedly connected to the hopper 16; the frame 19 serves to support the hopper 16. The material pipe 18 is used for downward feeding of materials.

[0044] As Figure 7As shown in the figure, the material pipe lifting system includes a rail disc 20 fixed on the turntable 10. A toothed piece 22 and a fixed material pipe rail groove 23 are fixedly connected to the rail disc 20. In this embodiment, the rail disc 20 is located above the turntable 10 and is integrally circular and hollow. The lower part of the rail disc 20 is fixedly connected to the turntable 10, and the upper part is fixedly connected to the toothed piece 22 and the fixed material pipe rail groove 23. In this embodiment, the toothed piece 22 and the fixed material pipe rail groove 23 form a complete circle. A material pipe rail support 24 and a winder 25 are also connected to the rail disc 20. The material pipe rail support 24 is located below the winder 25 and is fixedly connected to the rail disc 20. The winder 25 is slidably connected to the rail disc 20 through a track. A lifting motor 26 is installed on the winder 25. The output end of the lifting motor 26 is connected to a motor gear 27. The motor gear 27 meshes with the toothed piece 22. When the lifting motor 26 is started, the motor gear 27 rotates along the toothed piece 22 and drives the winder 25 to slide along the track. A sliding material pipe rail groove 28 is fixedly connected to the winder 25. One end of the sliding material pipe rail groove 28 close to the fixed material pipe rail groove 23 is flush with the fixed material pipe rail groove 23, and the other end gradually slopes downward.

[0045] The inside of the material pipe 18 is equipped with a shaftless spiral, which makes the feeding uniform and stable. The shaftless spiral has a large elasticity. Affected by it, the material pipe is not easy to bend, and the bending degree has a certain limit. Therefore, the fixed material pipe rail groove 23 mainly guides the material pipe 18 led out from the screw conveyor 17 with a certain bending degree; the winder 25 mainly winds the material pipe 18 around the equipment with force, playing the role of lifting the material pipe opening; the material pipe rail support 24 mainly plays the role of supporting and guiding the material pipe 18. The part of the material pipe 18 that leaves the fixed material pipe rail groove 23 is in a suspended state and will show the phenomena of sagging and natural straightening. The material pipe rail support 24 restricts these phenomena and makes the material pipe 18 run according to the set bending degree and track.

[0046] As Figure 7 - 8 shown in the figure, the winder 25 is located above the toothed piece 22. The lifting motor 26 is fixedly installed on the winder 25. The shaft of the lifting motor 26 is vertically downward and passes through the winder 25. The motor gear 27 is installed below and meshes with the toothed piece 22. Inside the winder 25, that is, on the side close to the rail disc 20, a set of vertical rail wheels 29, a set of sliding balls 30, and a set of horizontal rail wheels 31 are also installed. The vertical rail wheels 29 and the sliding balls 30 form a lever-like stable form under the common constraint of the surface of the rail disc 20 and the toothed piece 22, playing the role of vertical positioning; the horizontal rail wheels 31 are attached to the inside of the toothed piece 22, and the motor gear 27 meshes with the outside of the toothed piece 22, thus forming horizontal positioning. The sliding material pipe rail groove 28 is located outside the winder 25. Rolling shafts 32 are installed at the bottom and outside of the sliding material pipe rail groove 28, enabling the material pipe 18 to slide without resistance.

[0047] As Figure 11As shown, there are multiple material tube rail supports 24, and the material tube rail supports 24 are only arranged below the tooth pieces 22. Since the winder 25 can only move along the tooth pieces 22, it drives the material tube 18 to be retracted or released only within the range of the tooth pieces 22.

[0048] As Figure 9 shown, the material tube rail support 24 includes a rail support base 33, a rail support bracket 34 and a rocker 35. The rail support base 33 is fixed on the rail disk 20. The rail support bracket 34 is in a horizontal position and can limit the material tube 18 in the vertical direction. The rocker 35 is in a vertical position and can limit the material tube 18 in the horizontal direction. The inner end of the rail support bracket 34, that is, the end close to the rail disk 20, is hinged to the rail support base 33, and the outer end is hinged to the rocker 35. One end of the rocker 35 is fixedly connected with a rocker gear 36, and the axial direction of the rocker gear 36 extends outwards and is hinged to the rail support bracket 34.

[0049] A sector tooth piece 37 is fixedly connected to the upper part of the rail support base 33, and a limit plate 38 is fixedly connected to the lower part. The sector tooth piece 37 and the limit plate 38 are hinged to the end of the rail support bracket 34 through a pin shaft in the middle. An intermediate gear 39 meshing with the sector tooth piece 37 and a second rack 40 meshing with the intermediate gear 39 are installed on the rail support bracket 34. The second rack 40 is arranged along the direction from the rail support base 33 to the rocker 35. There are two groups of teeth on the second rack 40, which are located on two surfaces respectively, that is, the two groups of teeth are arranged at 90°. The two groups of teeth are located at both ends of the second rack 40 respectively. The intermediate gear 39 meshes with one end of the second rack 40, and the other end of the second rack 40 meshes with the rocker gear 36. The axial directions of the intermediate gear 39 and the rocker gear 36 are at 90°, and the transmission is realized by the teeth on the two surfaces of the second rack 40 at 90°. The rocker gear 36 and the rocker 35 are fixedly installed together, hinged to the outer end of the rail support bracket 34. The axial direction of the rocker gear 36 extends outwards and is installed with a rocker spring 41. The rocker spring 41 is coaxially assembled with the rocker 35 to limit the free movement of the rocker 35. Two limit grooves 42 are arranged on the limit plate 38, and a positioning detent 43 is fixedly connected to the rail support bracket 34. The two limit grooves 42 are arranged along the movement direction of the rail support bracket 34. Initially, the positioning detent 43 is located in one of the limit grooves. When the rail support bracket 34 moves, the positioning detent 43 moves to the other limit groove. After the movement of the rail support bracket 34 is completed, the positioning detent 43 is located in the other limit groove 42 to limit the rail support bracket 34.

[0050] In this way, when the rail support bracket 34 rotates along the pin shaft, the intermediate gear 39 rotates under the action of the sector tooth piece 37, and at the same time drives the second rack 40 to move. The second rack 40 drives the rocker gear 36 to rotate, and the rocker gear 36 drives the rocker 35 to rotate, realizing that the rocker 35 is in the horizontal position or the vertical position.

[0051] As Figure 10As shown, when the winder 25 rotates clockwise, the outlet of the material pipe 18 will rise. At the same time, the distance between the sliding material pipe rail groove 28 and the fixed material pipe rail groove 23 will become larger and larger, and the material pipe 18 will be suspended and sag. At this time, the material pipe rail support 24 will rotate out and support the material pipe 18. When the material pipe rail support 24 rotates outward, the tipping plate 35 will rise at a certain angle to restrain the elastic outward extension of the material pipe 18. When the winder 25 rotates counterclockwise, the material pipe rail support will extend the tipping plate 35 and return to its original position in the reverse order. In this embodiment, a total of five groups of material pipe rail supports 24 are installed on the equipment, and other quantities can also be installed according to actual situations.

[0052] As Figure 11 shown, the limit plate 38 on the material pipe rail support 24 is located at the lower part and is locked in position through a pin shaft and a flat key and cannot rotate. There are two limit grooves 42 on the limit plate 38. In this embodiment, they are groove A and groove B respectively. A positioning detent 43 is installed on the rail support 34. When the positioning detent 43 is in groove A, it is in the reset state (as Figure 12 ), and when it is in groove B, it is in the working state (as Figure 13 ).

[0053] As Figure 12 and Figure 14 shown, a toggle shaft 44 is provided below the winder 25, and a guide groove 45 is provided on the rail support 34. The guide groove 45 is of a special shape and is arranged facing the toggle shaft 44 above, with both ends open, and the toggle shaft 44 can slide along the guide groove 45. As Figure 15 shown, when the winder 25 rotates clockwise, when the toggle shaft 44 reaches the rail support 34, it enters the guide groove 45. As Figure 16 shown, the toggle shaft 44 pushes the rail support 34 to rotate clockwise from the reset state. When it rotates 70°, the tipping plate 35 on the rail support 34 has rotated out of the material pipe part, and the tipping plate 35 has tilted and is no longer affected by the material pipe. At this time, the intermediate gear 39 on the rail support 34 meshes with the sector gear segment 37 on the rail support seat 33, as Figure 17 shown. The rail support 34 continues to rotate 15°, as Figure 18 shown. The pitch arc length of the sector gear segment 37 is 15.71 mm, and the pitch arc length corresponding to the 90° central angle of the intermediate gear is also 15.71 mm. Then, the intermediate gear 39 is driven to rotate 90°. As Figure 19 shown, the pitch circles of the intermediate gear 39 and the tipping plate gear 36 are equal. The tipping plate gear 36 is also driven to rotate 90° under the drive of the second rack 40. The tipping plate gear 36 is fixedly installed together with the tipping plate 35, and the tipping plate 35 also rotates 90°, rotating from the horizontal direction to the vertical direction. As Figure 20As shown, at this time, the positioning catch 43 is in the B groove position, the toggle shaft 44 on the winder 25 rotates out of the guide groove 45, and the rail bracket 34 stops rotating. At this time, the rail bracket 34 is in a horizontal state and holds up the material pipe 18, and the rocker 35 is in a vertical state to limit the outward expansion of the material pipe 18, realizing the limitation of the material pipe 18.

[0054] In this embodiment, when the winder 25 moves in the clockwise direction, it drives the material pipe 18 to wind around the periphery of the equipment, causing the lower discharge port of the material pipe 18 to rise accordingly until the winder 25 rotates from one end of the tooth segment 22 to the other end, the winding of the material pipe 18 is completed, and the lower discharge port also rises to the highest point. At this time, the feeding is also completed. When disassembling the equipment, there is no need to perform additional disassembly, assembly, and fixation on the material pipe 18. When feeding the furnace, fix the equipment at the furnace opening, start the motor to reverse, drive the winder 25 to rotate back from the end of the tooth segment 22, and the material pipe 18 is slowly lowered through the sliding material pipe rail groove 28, and the lower discharge port gradually drops to the lowest point. During the movement, the movement of the corresponding material pipe rail support 24 is opposite to that during the ascent: the toggle shaft 44 on the winder 25 enters the guide groove 45 from the other end of the guide groove 45, pushes the rail bracket 34 to rotate, and at the same time, the positioning catch 43 disengages from the B groove and moves towards the A groove, the intermediate gear 39 reverses, drives the rocker 35 to rotate towards the horizontal position through the second rack 40 until the toggle shaft 44 disengages from the guide groove 45, and the positioning catch 43 returns to the A groove for positioning, and the entire material pipe rail support 24 returns to the state when retracted as Figure 7 shown until all the material pipe rail supports 24 are retracted and the lower part of the material pipe 18 is completed.

[0055] Fix the feeder on the crucible through the fixing system, put the sand material into the hopper 16, and then rotate the winder 25 of the material pipe 18 in the clockwise or counterclockwise direction to adjust the height of the outlet of the material pipe 18 until it is appropriate. Then, start the feeder, the feeder starts to rotate, and the screw conveyor 17 starts to feed. The material pipe 18 rotates around the crucible for spreading the material. Rotating at a constant speed and spreading the material at a low position, there is neither dust nor uneven spreading.
