Technical Field

[0001] This invention relates to the field of heating furnace design technology, and in particular to a quantitative feeding device for a heating furnace. Background Technology

[0002] Centrifugal glass wool is a fibrous material made by centrifugally blowing molten glass and spraying it with thermosetting resin. After further heat curing and deep processing, it can be made into a series of products with various uses.

[0003] Currently, Chinese patent publication number CN111099830A, published on May 5, 2020, discloses an environmentally friendly glass wool and its preparation method. The preparation method specifically includes the following steps: S1, adding crushed glass, soda ash, dolomite, nano-alumina, calcium oxide, and magnesium silicate into an industrial kiln for manufacturing glass wool and melting them at a temperature of 1500°C to 1750°C for 30 to 45 minutes to obtain molten glass for glass wool production; S2, centrifuging the molten glass into a glass wool centrifuge to obtain glass fibers, and uniformly spraying an adhesive onto the surface of the glass fibers; S3, collecting the glass fibers using a cotton collecting machine and then conveying them to a curing furnace for curing to obtain glass wool.

[0004] In the initial stage of glass wool processing, various different materials need to be fed into an industrial kiln (i.e., a heating furnace) for melting.

[0005] Meanwhile, Chinese patent CN114436502A, published on May 6, 2022, discloses an energy-saving and environmentally friendly glass furnace with intelligent control feeding. It includes a melting furnace with a triangular support below it. Burners are symmetrically embedded at the top of the furnace's outer side, with combustion nozzles connected to their outlets. A quantitative unloading assembly is connected to the furnace's inlet, and the furnace is connected to an autonomous feeding assembly via this assembly. The autonomous feeding assembly includes a mixing transfer tank connected to the inlet of the quantitative unloading assembly. A feeding pipe is located on one side of the mixing transfer tank, with a feeding hopper connected to the bottom of one side of the feeding pipe. A discharge pipe is connected to the top of the feeding pipe, with its outlet connected to the mixing transfer tank. A conveying auger is rotatably connected to the inner side of the feeding pipe, and the mixing transfer tank is located on the middle side of the inner side of the mixing transfer tank. A drive shaft is rotatably connected at the position of the mixing transfer tank, and a positioning ring frame is set at the middle of the bottom of the inner side of the mixing transfer tank. A transverse spiral roller is symmetrically connected between the positioning ring frame and the mixing transfer tank. The output end of the drive shaft passes through the end face of the mixing transfer tank and is connected to a dual-shaft drive motor. A longitudinal spiral roller is set at the bottom of the mixing transfer tank, and a bevel gear B is set at the output end of the transverse spiral roller. A bevel gear A that meshes with bevel gear B is set on the outer side of the drive shaft. A first impact paddle and a second impact paddle are set sequentially from top to bottom in the middle of the drive shaft. The quantitative unloading assembly includes a unloading pipe. A central frame is set at the middle of the inner side of the unloading pipe, and a rotating shaft is symmetrically connected between the unloading pipe and the central frame. A unloading flap is sleeved on the outer side of the rotating shaft, and a rotating support is set through the end face of the unloading pipe at the output end of the rotating shaft. The rotating support is connected by a lever. An opening and closing mechanism is set on one side of the unloading pipe.

[0006] In this type of intelligent control and energy-saving and environmentally friendly glass furnace, the feed hopper is used to store the materials to be input. The feeding pipe connected to the feed hopper is actually a bucket elevator. The bucket elevator can lift the materials in the feed hopper and transport them into the transfer tank. Then, the quantitative feeding of materials is achieved through the quantitative unloading component at the bottom of the transfer tank.

[0007] When this type of kiln is used in the preparation of glass wool, there are many types of materials, including crushed glass, soda ash, dolomite, nano alumina, calcium oxide, and magnesium silicate. Therefore, a single feed hopper, bucket elevator, and transfer tank cannot meet the feeding needs of multiple materials. At this time, it is urgent to design a feeding device that can feed multiple materials. Summary of the Invention

[0008] The purpose of this invention is to provide a quantitative feeding device for a heating furnace, which can conveniently meet the feeding needs of various materials.

[0009] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a quantitative feeding device for a heating furnace, comprising a plurality of transfer tanks located on the upper side of the heating furnace and equipped with quantitative unloading components, a plurality of bucket elevators corresponding to the plurality of transfer tanks, a discharge pipe connected at one end to the discharge port at the upper end of the bucket elevator and at the other end to the upper end of the transfer tank, and a hopper connected to the feed port at the lower end of the bucket elevator. The plurality of hoppers are evenly spaced on the ground, and a feeding component for feeding materials from material bags into the hoppers is provided between the plurality of hoppers.

[0010] By adopting the above technical solution, the feeding components can be used to feed different materials from various material bags into different silos, thereby realizing the separate feeding of multiple materials into different silos. Then, the bucket elevator is used to lift the materials in the silos and transport them into the transfer tank along the discharge pipe. The transfer tank can use the quantitative unloading components to control the weight of the materials entering the furnace, thus conveniently meeting the feeding needs of multiple materials.

[0011] A further configuration of the present invention is as follows: the feeding assembly includes a frame, a conveyor chain mounted on the frame with one end positioned above any hopper, a support plate mounted on the frame and located below the conveyor chain, a drive shaft rotatably connected to the frame and located within one end of the conveyor chain, a drive gear mounted on the upper end of the drive shaft and meshing with the conveyor chain, a drive motor mounted on the frame with its output shaft connected to the lower end of the drive shaft, a driven shaft rotatably connected to the frame and located within the end of the conveyor chain away from the drive shaft, a driven gear mounted on the upper end of the driven shaft and meshing with the conveyor chain, a plurality of clamping members mounted on the conveyor chain for clamping the upper side of the material bag, a support rail mounted on the frame for supporting the lower side of the material bag, an opening at one end of the support rail and located above the hopper, and a cutting blade mounted at the end of the support rail located within the opening for cutting the lower side of the material bag. The conveyor chain is waist-shaped, and the support rail is U-shaped and used in conjunction with the conveyor chain.

[0012] By adopting the above technical solution, when the material in the material bag needs to be put into the silo, the material in the material bag contains dust after it is put out. Inhaling this dust will affect human health.

[0013] At this time, the conveyor chain set on the frame is waist-shaped. One end of the conveyor chain can be placed above the hopper and the other end can be used by the operator to put the material bag, so that the operator is away from the hopper and the possibility of the operator inhaling dust can be reduced.

[0014] The material bag is clamped at the top and connected to a conveyor chain, while its bottom is supported on a support rail. The bag then moves towards the hopper along the conveyor chain. When the bag reaches the opening on the support rail, a cutting blade cuts open the bottom of the bag. As the bag continues to move, the material in the bag above the hopper is fed into the hopper through the cut opening. After the material in the bag is emptied, the remaining empty bag is conveyed back to the operator. The operator can then remove the empty bag from the clamp. As one bag after another is conveyed to the hopper, the material is finally dispensed. The entire process is safe and convenient, reducing the possibility of dust inhalation for the operator.

[0015] A further embodiment of the present invention is that the clamping member includes a suspension rod extending in a vertical direction, a hook located at the upper end of the suspension rod, a hanging plate disposed on the side of a plurality of chain plates disposed in the transmission chain, a hanging hole opened on the hanging plate for the hook to pass through, a horizontal rod disposed at the lower end of the suspension rod, and two metal clamps disposed at both ends of the horizontal rod and used to clamp the upper ends of the material bag respectively.

[0016] By adopting the above technical solution, the metal clamps at both ends of the horizontal bar are first used to clamp the material bag at both ends of the upper side. Then, the hook at the upper end of the suspension rod can be passed through the hanging hole on the hanging plate. At this time, the material bag and the clamping parts can be moved together with the conveyor chain.

[0017] A further feature of the present invention is that the clamping member further includes a discharge auxiliary spring with one end connected to the end of the horizontal bar and the other end connected to the metal clamp.

[0018] By adopting the above technical solution, when the metal clamp moves the material bag to the opening above the hopper, the material bag loses the support of the support track and falls downward under its own weight. Since one end of the unloading auxiliary spring is connected to the end of the horizontal rod and the other end is connected to the metal clamp, the material bag will be lifted upward under the elastic restoring force of the unloading auxiliary spring after it has fallen a certain distance. At this time, the material bag can vibrate up and down through the unloading auxiliary spring, which will ultimately facilitate the rapid feeding of the material bag into the hopper below and prevent material residue from remaining in the material bag.

[0019] A further provision of the present invention is as follows: a connecting shaft is provided on the frame at the opening, with its lower end fixed to the frame and extending vertically upward; a rotating tube is sleeved on the upper end of the connecting shaft; a first connecting ring is provided on the circumference of the lower end of the rotating tube; a second connecting ring is provided on the circumference of the connecting shaft; a reset torsion spring is sleeved on the connecting shaft, with its lower end fixed to the second connecting ring and its upper end fixed to the first connecting ring; a connecting rod is provided on the upper end of the rotating tube for the suspension rod to abut against; and a striking arm is provided on the outer wall of the rotating tube to strike the cut material bag after the rotating tube rotates.

[0020] By adopting the above technical solution, when the clamping component moves the material bag in the opening, the suspension rod inside the clamping component will abut against the connecting rod at the upper end of the rotating tube, thereby driving the connecting rod to swing. After the connecting rod swings, it can drive the striking arm to swing through the rotating tube. Since the rotating tube rotates relative to the connecting shaft, the reset torsion spring can be torn.

[0021] When the clamping device continues to move the material bag and the suspension rod separates from the connecting rod, the return torsion spring will elastically recover. The return torsion spring will drive the rotating tube to rotate in the opposite direction, thereby causing the connecting rod and the striking arm to swing in the opposite direction to reset. After the connecting rod swings in the opposite direction to reset, it can wait for the next clamping device to arrive. After the striking arm swings in the opposite direction to reset, it can strike the outer wall of the moving material bag, thereby vibrating the material bag moving above the hopper. Ultimately, this will further facilitate the rapid feeding of the material bag into the hopper below, preventing material residue in the material bag.

[0022] A further feature of the invention is that the striking arm is made of spring steel.

[0023] By adopting the above technical solution, the striking arm is made of spring steel, which makes the striking arm elastic, thereby preventing the striking arm from hitting the moving material bag and affecting the normal movement of the material bag.

[0024] A further feature of the present invention is that the end of the support rail is provided with an opening groove for the cutting blade to pass through, and the lower surface of the support rail is provided with a cutting motor whose output shaft is connected to the cutting blade.

[0025] By adopting the above technical solution, the cutting blade is driven to rotate by a cutting motor, and the cutting blade passing through the opening slot can quickly cut the material bag.

[0026] A further feature of the present invention is that the width of the opening groove is greater than the thickness of the cutting blade.

[0027] By adopting the above technical solution, after the cutting blade cuts open the material bag, since the width of the opening groove is greater than the thickness of the cutting blade, the material falling near the cutting blade can fall into the feed bin through the opening groove, thus preventing the material from staying on the support rail after falling.

[0028] A further setting of the present invention is that: a support frame for supporting on the ground is provided on the lower side of the frame, and a plurality of universal wheels for abutting on the ground are provided at the lower end of the support frame.

[0029] By adopting the above technical solution, when it is necessary to feed materials into other feed bins, the support frame on the lower side of the frame is utilized, and a plurality of universal wheels for abutting on the ground are provided at the lower end of the support frame. The feeding component can be conveniently moved through the universal wheels, and finally, the feeding component can be conveniently moved to different positions of the feed bins.

[0030] A further setting of the present invention is that: a baffle in the shape of "冂" is provided on the upper side of the feed bin.

[0031] By adopting the above technical solution, by using the baffle in the shape of "冂" provided on the upper side of the feed bin, when the material is fed into the feed bin and the dust splashes upward, the baffle can block the dust, reduce the splashed material, and is beneficial to the efficient falling of the material into the corresponding feed bin.

[0032] The beneficial effect of the present invention is that: the feeding component can be used to separately feed different materials in multiple material bags into different feed bins, thereby realizing the separate feeding of multiple materials into different feed bins. Subsequently, the bucket elevator is used to lift the materials in the feed bin and convey them into the transfer tank along the feeding pipe. The transfer tank can use the quantitative discharging component to control the weight of the materials entering the furnace body, and finally, it can conveniently meet the feeding requirements of multiple materials;

[0033] When feeding material using the feeding assembly, the two metal clamps inside the clamping device first clamp the upper ends of the material bag. Then, the hook at the upper end of the suspension rod passes through the hanging hole on the hanging plate. After being clamped by the clamping device, the material bag is connected to the conveyor chain. Simultaneously, the lower side of the material bag is supported on the support rail. The material bag then moves towards the hopper side under the drive of the conveyor chain. When the material bag is conveyed to the position where the support rail is at the opening, the cutting motor drives the cutting blade to rotate, cutting open the lower side of the material bag. As the material bag continues to be conveyed, the material bag above the hopper can be fed into the hopper through the cut opening on its lower side. When the metal clamp moves the material bag into the opening above the hopper, the material bag loses the support rail and falls downwards under its own weight. Since one end of the unloading auxiliary spring is connected to the end of the horizontal rod and the other end to the metal clamp, the material bag is lifted upwards again by the elastic restoring force of the unloading auxiliary spring after falling a certain distance. At this point, the material bag can vibrate up and down through the unloading auxiliary spring, which facilitates the rapid delivery of material from the bag into the lower hopper, preventing material residue from remaining inside the bag. Simultaneously, when the clamping device moves the material bag within the opening, the suspension rod inside the clamping device abuts against the connecting rod at the upper end of the rotating tube, causing the connecting rod to swing. This swing, in turn, drives the striking arm to swing through the rotating tube. Since the rotating tube rotates relative to the connecting shaft, the return torsion spring twists. When the clamping device continues to move the material bag and the suspension rod separates from the connecting rod, the return torsion spring recovers its elasticity. This spring causes the rotating tube to rotate in the opposite direction, which in turn causes the connecting rod and striking arm to swing in the opposite direction for reset. After the connecting rod resets in the opposite direction, it awaits the arrival of the next clamping device. The striking arm, after resetting in the opposite direction, strikes the outer wall of the moving material bag, thus vibrating the bag moving above the hopper. This further facilitates the rapid delivery of material from the bag into the lower hopper, preventing material residue from remaining inside the bag.

[0034] After the material bag is filled, the remaining empty material bags can continue to be transported back to the operator's end by the conveyor chain. The operator can then open the metal clamp and remove the empty material bag from the clamp. As one material bag after another is conveyed to the hopper by the conveyor chain, the material filling in the hopper is finally completed. The entire filling process is safe and convenient, reducing the possibility of operators inhaling dust. Attached Figure Description

[0043] A quantitative feeding device for a heating furnace, referring to Figure 1 , Figure 2 , this quantitative feeding device for the heating furnace includes a transfer tank 1, a bucket elevator 2, a feed pipe 3 and a storage bin 4. Among them, multiple transfer tanks 1 are provided and are all located above the heating furnace. And a quantitative discharging component is provided in the transfer tank 1 itself. The materials entering the transfer tank 1 rely on the quantitative discharging component to feed the heating furnace with quantitative materials. The quantitative discharging component is prior art, and its specific structure will not be elaborated here.

The lower end of the bucket elevator 2 is located below the ground. At the same time, a baffle 41 in the shape of "冂" is integrally provided on the upper side of the storage bin 4, and the baffle 41 can block the splashing dust.

[0044] Referring to Figure 2 , Figure 3 , a feeding component 5 is provided between multiple storage bins 4. The feeding component 5 is used to feed the materials in the material bag into the storage bin 4. This feeding component 5 includes a frame 51, a transmission chain 52, a support plate 53, a driving shaft 54, a driving gear 55, a driving motor 56, a driven shaft 57, a driven gear 571, a clamping member 58, a support track 59, an opening 501, and a cutting blade 502. Among them, the frame 51 is used to be placed on the ground in front of the storage bin 4. And a support frame 7 for supporting on the ground is welded to the lower side of the frame 51. At the same time, four universal wheels 71 for abutting on the ground are fixed to the lower end of the support frame 7 by bolts. The frame 51 can move on the ground relying on the universal wheels 71. The transmission chain 52 is arranged on the upper side of the frame 51, and the transmission chain 52 is in a waist shape. The support plate 53 is fixed to the frame 51 by bolts and is used to support under the transmission chain 52, and the support plate 53 is also in a waist shape.

[0045] Referring to Figure 2 , the lower end of the driving shaft 54 is rotationally connected to the frame 51 through a bearing and the upper end is located inside one end of the transmission chain 52. The driving gear 55 is key-connected to the upper end of the driving shaft 54 and meshes with the transmission chain 52. And the driving motor 56 is fixed to the frame 51 by bolts and the output shaft is connected to the lower end of the driving shaft 54.

The driven gear 571 is key-connected to the upper end of the driven shaft 57 and meshes with the transmission chain 52. At this time, relying on the driving motor 56, the driving gear can be driven to rotate, and thus the transmission chain 52 can be driven to drive through the rotation of the driving gear and the driven gear 571.

[0046] Reference Figure 2 , Figure 3 , Figure 4 Multiple clamping members 58 are provided and are all disposed on the conveyor chain 52. The clamping members 58 can be used to clamp the upper side of the material bag. The clamping members 58 include a suspension rod 581, a hook 582, a hanging plate 583, a hanging hole 584, a horizontal rod 585, a metal clamp 586, and a discharge auxiliary spring 587. The suspension rod 581 extends vertically, and the hook 582 is welded to the upper end of the suspension rod 581. At the same time, multiple hanging plates 583 are provided and welded to the sides of multiple chain plates in the conveyor chain 52.

[0047] Reference Figure 2 , Figure 3 The support rail 59 is fixed to the frame 51 by bolts and is located below the conveyor chain 52. The opening 501 is opened at one end of the support rail 59 and is located above the hopper 4. At this time, the support rail 59 is U-shaped to cooperate with the conveyor chain 52.

The width of the opening groove 591 is greater than the thickness of the cutting blade 502. The lower surface of the support rail 59 is fixed with a cutting motor 592 connected to the cutting blade 502 by bolts. After the cutting motor 592 drives the cutting blade 502 to rotate, the cutting blade 502 can be used to cut the lower side of the material bag.

[0048] Reference Figure 3 , Figure 4 , Figure 5A connecting shaft 6 is also provided on the frame 51 at the position of the opening 501. The lower end of the connecting shaft 6 is welded to the frame 51 and extends vertically upward. A rotating tube 61 is sleeved on the upper end of the connecting shaft 6. A first connecting ring 611 is welded to the circumference of the lower end of the rotating tube 61. A second connecting ring 62 is welded to the circumference of the connecting shaft 6. A reset torsion spring 63 is sleeved on the connecting shaft 6, with its lower end welded to the second connecting ring 62 and its upper end welded to the first connecting ring 611. A connecting rod 612 for the suspension rod 581 to abut is also welded to the upper end of the rotating tube 61. A striking arm 613 is welded to the outer wall of the rotating tube 61. The striking arm 613 is made of spring steel. After the rotating tube 61 rotates, the striking arm 613 can be used to strike the cut material bag.

[0049] Principle: The feeding component 5 can be used to put different materials from various material bags into different hoppers 4, thereby realizing the separate feeding of multiple materials into different hoppers 4. Then, the bucket elevator 2 is used to lift the materials in the hoppers 4 and transport them into the transfer tank 1 along the discharge pipe 3. The transfer tank 1 can use the quantitative discharge component to control the weight of the materials entering the furnace body, thus conveniently meeting the feeding needs of multiple materials.

[0050] When feeding material using the feeding component 5, the two metal clamps 586 inside the clamping member 58 first clamp the material bag at both ends on the upper side. Then, the hook 582 at the upper end of the suspension rod 581 passes through the hanging hole 584 on the hanging plate 583. At this time, the material bag is connected to the conveyor chain 52 after being clamped by the clamping member 58. At the same time, the lower side of the material bag is supported on the support rail 59. Then, the material bag moves towards the hopper 4 under the drive of the conveyor chain 52. When the material bag is conveyed to the position of the support rail 59 at the opening 501, the cutting motor 592 drives the cutting blade 502 to rotate. 502 cuts open the bottom of the material bag. As the material bag continues to be conveyed, the material bag located above the hopper 4 can be fed into the hopper 4 through the cut opening on the bottom. When the metal clamp 586 moves the material bag into the opening 501 above the hopper 4, the material bag loses the support of the support track 59 and falls downwards under its own weight. Since one end of the unloading auxiliary spring 587 is connected to the end of the horizontal rod 585 and the other end is connected to the metal clamp 586, the material bag will be lifted upwards again under the elastic restoring force of the unloading auxiliary spring 587 after falling a certain distance. At this time, the material bag can vibrate up and down through the unloading auxiliary spring 587, which will facilitate the rapid feeding of the material bag into the lower hopper 4, preventing material residue in the material bag. Simultaneously, when the clamping member 58 moves the material bag within the opening 501, the suspension rod 581 inside the clamping member 58 will abut against the connecting rod 612 at the upper end of the rotating tube 61, causing the connecting rod 612 to swing. The swinging of the connecting rod 612 will then drive the striking arm 613 to swing through the rotating tube 61. Since the rotating tube 61 rotates relative to the connecting shaft 6, the return torsion spring 63 will twist. When the clamping member 58 continues... After the material bag moves and the suspension rod 581 separates from the connecting rod 612, the reset torsion spring 63 can elastically recover. The reset torsion spring 63 can drive the rotating tube 61 to rotate in the opposite direction, thereby driving the connecting rod 612 and the striking arm 613 to swing in the opposite direction to reset. After the connecting rod 612 swings in the opposite direction to reset, it can wait for the arrival of the next clamping part 58. After the striking arm 613 swings in the opposite direction to reset, it can strike the outer wall of the moving material bag, thereby vibrating the material bag moving above the hopper 4. Ultimately, this can further facilitate the rapid input of the material bag into the hopper 4 below, avoiding material residue in the material bag.

[0051] After the material bag is filled, the remaining empty material bag can continue to be transported back to the operator's end by the conveyor chain 52. Then the operator can open the metal clamp 586 and remove the empty material bag from the clamp 58. As one material bag after another is conveyed to the hopper 4 by the conveyor chain 52, the material filling in the hopper 4 can be completed. The whole filling process is safe and convenient, reducing the possibility of operators inhaling dust.
