Description
Technical Field
[0001] This invention relates to the field of batching system technology, and particularly to a glass sand batching system. Background Technology
[0002] A batching system refers to a feeding system in the processing industry consisting of a series of devices used to supply materials to production equipment. Glass sand is a type of artificial stone, and its production process requires batching, such as mixing quartz sand, alkali, and lime powder. This mixture is then fed into a high-temperature furnace on the discharge side of the mixing chamber. The mixture of quartz sand, alkali, and lime powder is heated to over 1000 degrees Celsius, transforming it into molten glass. For example, patent application number 2016100384655 discloses a method for preparing glass sand, which involves rapid cooling and crushing after melting to obtain glass sand.
[0003] However, if materials are directly fed into the high-temperature furnace after being mixed in the mixing chamber without material control, the melting efficiency will be affected by the large amount of material fed at once. Even with a material control mechanism to keep the material above the high-temperature furnace and implement staged feeding, excessive material accumulation above the furnace opening due to continued feeding can lead to material spillage. Furthermore, the mixture may concentrate similar components due to this accumulation, resulting in uneven distribution of the glass melt after it is melted in the high-temperature furnace, thus affecting the quality of the glass frit. Summary of the Invention
[0004] The technical problem to be solved by the present invention is that a swing arm feeding function is set in the horizontal part of the conveying chamber. The material is fed into the high-temperature furnace in stages by the push plate at the front end of the swing arm. First, it can avoid the accumulation of material in the horizontal part of the conveying chamber. Second, the material can be mixed again when it is conveyed to the push plate side, thereby improving the quality of glass sand.
[0005] The technical solution of the present invention is a glass sand batching system, including a crushing device, a mixing device connected to the discharge side of the crushing device, a high-temperature furnace located at the discharge side of the mixing device, and a feeding channel connected between the feed side of the high-temperature furnace and the discharge side of the mixing device. The feeding channel includes a feed hopper and a discharge hopper welded together. The feed end of the feed hopper is connected to the discharge side of the mixing device, and the discharge hopper is connected to the feed side of the high-temperature furnace. A stirring mechanism is provided at the connection between the discharge hopper and the feed hopper, located inside the discharge hopper. A pushing mechanism is provided on the discharge hopper in the direction of the discharge end of the stirring mechanism. The feed hopper gradually slopes downward toward the discharge hopper, and the discharge hopper is horizontal. The mixing mechanism includes a mixing rod that is connected to the discharge hopper and close to the feed hopper. Bearings are fixed on both sides of the discharge hopper, and the two ends of the mixing rod are respectively mounted on the two bearings. The two ends of the mixing rod extend through to both sides of the discharge hopper. The pushing mechanism includes first connecting rods located on both sides of the discharge hopper and respectively fixed to the two ends of the mixing rod. The pushing mechanism also includes long rods located on both sides of the discharge hopper. The middle parts of the two long rods are respectively connected to the two first connecting rods via hinges. One end of the two long rods extends towards the discharge end of the discharge hopper and is connected to a push plate. The other end of the long rod extends toward the discharge end of the feed hopper and is connected to a second connecting rod via a hinge. A motor is fixed on the feed hopper, and the motor's actuation shaft is connected to the second connecting rod. When the second connecting rod rotates, the long rod drives the first connecting rod to rotate. Under the rotation of the first connecting rod, the long rod drives the push plate to perform intermittent pushing action at the discharge end of the discharge hopper. Under the rotation of the first connecting rod, the stirring rod completes the stirring action in the discharge hopper. The stirring mechanism also includes material teeth arranged on the stirring rod along its length.
[0006] As a further preferred embodiment, a baffle is fixed to the top of the discharge hopper, the baffle covering the top of the stirring rod and simultaneously covering the material teeth on the stirring rod inside the discharge hopper.
[0007] As a further preferred embodiment, the pusher plate has a push cavity on the side facing the stirring rod.
[0008] As a further preferred embodiment, the connection between the feed hopper and the discharge hopper is provided with a gradually downward sloping surface, the lowest end of which is connected to the feed end of the discharge hopper and is also close to the feed teeth.
[0009] As a further preferred embodiment, the surface of the feed tooth is provided with a plurality of diversion plates along its length, the plurality of diversion plates being wavy, and each wavy profile of the diversion plate passing through each of the slots on the diversion plate.
[0010] As a further preferred embodiment, the discharge hopper is provided with a tilting plate. One end of the tilting plate extends to near the push plate and is rotatably connected to the bottom surface of the inner cavity of the discharge hopper via a rotating shaft. The end of the tilting plate near the feed side of the push plate gradually tilts downward and is movably connected to the discharge hopper by a rotating connection. The end of the tilting plate near the material teeth gradually tilts upward, and a spring is connected to the bottom surface of the tilted end of the tilting plate. The bottom end of the spring is elastically connected to the bottom surface of the inner cavity of the discharge hopper.
[0011] As a further preferred embodiment, a wheel is installed at one end of the stirring rod. The wheel is located inside the discharge hopper, and the bottom of the wheel is close to the raised end of the lifting plate. A roller is fixed on the wheel and can roll and contact the top surface of the raised end of the lifting plate when it rotates. When the roller contacts the raised end of the lifting plate, it can cause the lifting plate to rotate downward around the rotating axis. When the roller follows the wheel to rotate until it separates from the top surface of the raised end of the lifting plate, the lifting plate rotates and rises under the support of the spring. A tape connects the bottom surface of the raised end of the lifting plate to the bottom surface of the inner cavity of the discharge hopper.
[0012] As a further preferred embodiment, the material teeth are located in several places, and the several material teeth are fixed in a ring array on the stirring rod, with a row of grooves opened on each of the material teeth.
[0013] The advantages of this invention compared to the prior art are: This invention uses a long rod as the power component for the pusher plate to complete the above-mentioned actions, which separates the pushing area of the pusher plate from the temporary storage area of the material on the discharge hopper, and the separation distance is relatively far. Thus, when the pusher plate puts the material into the high-temperature furnace, it not only improves the melting efficiency, but also ensures that a relatively far distance is formed between the furnace opening and the material storage area on the discharge hopper.
[0014] In addition, driven by the rotation of the connecting rod, the stirring rod can also complete the stirring action in the discharge hopper. Since the stirring mechanism also includes material teeth set along the length of the stirring rod, when the long rod moves forward, backward, and swings in the inlet and outlet direction of the discharge hopper, it will also use the first connecting rod to drive the stirring rod to rotate. The stirring rod will also rotate once in the forward and reverse directions in the discharge hopper with the material teeth on it. Every time the first connecting rod swings left and right, it will drive the stirring rod to rotate left and right once in the discharge hopper. Since the stirring rod is located in the discharge hopper, and the material flowing into the discharge hopper for temporary storage is also located in the same area as the stirring rod, the existence of the stirring rod and the material teeth plays three roles for the material. The first role is to partially intercept the material flowing into this area of the discharge hopper, preventing the material from flowing directly into the high-temperature furnace due to excessive flow velocity when entering the discharge hopper. The second role is that when the stirring rod rotates with the material teeth, it can also bring the intercepted material from the feed side of the stirring rod to the discharge side of the stirring rod. The third function is that, under the stirring action of the stirring rod with the material teeth, the material is stirred twice in the discharge hopper, so that the components such as quartz sand, alkali, and lime powder that make up the material are fully mixed twice and then sent to the discharge side of the stirring rod. After being pushed by the pusher plate, it is put into the high-temperature furnace for melting treatment, so as to improve the quality of the melt. The quality of the cooled glass sand is also improved. Attached Figure Description

[0017] The above and other embodiments and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0018] In one implementation, such as Figures 1-7 As shown: The glass sand batching system provided in this embodiment includes a crushing device 1, a mixing device 2 connected to the discharge side of the crushing device 1, a high-temperature furnace 3 located at the discharge side of the mixing device 2, and a feeding channel 4 connected between the feed side of the high-temperature furnace 3 and the discharge side of the mixing device 2. The crushing device 1 can be a crusher or a pulverizer, and the mixing device 2 can be a mixing chamber. Since the material used to make glass sand is composed of quartz sand, alkali, lime powder, and many other materials, it needs to be processed by the crushing device 1 and the mixing device 2 before being added to the high-temperature furnace 3 for melting, and then transported to the high-temperature furnace 3 by the feeding channel 4. The feeding channel 4 in this invention is not just a single feeding hopper. In this invention, the feeding channel 4 includes a feeding hopper 5 and a discharging hopper 6 welded together. That is, the feeding channel 4 is formed by splicing the feeding hopper 5 and the discharging hopper 6. The feeding hopper 5 feeds... The feed hopper 5 is connected to the discharge side of the mixing equipment 2. It serves as a material guide. After the material is initially mixed by the mixing equipment 2, it is sent to the discharge hopper 6 by the feed hopper 5. Since the discharge hopper 6 is horizontal, the material is stationary for a short time when it is tilted and guided from the feed hopper 5 to the discharge hopper 6. That is, the material is stationary and waiting before being put into the high-temperature furnace 3. This allows the material that fell into the high-temperature furnace 3 in the previous stage to be melted at high temperature. Then, the subsequent material that is stationary on the discharge hopper 6 is put into the high-temperature furnace 3 for high-temperature melting. This prevents the material from being put into the furnace too much at once and affecting the melting efficiency. In order to allow the material that is stationary on the discharge hopper 6 to be put into the high-temperature furnace 3 in stages when controlled, a pushing mechanism 8 is also provided on the discharge hopper 6. A stirring mechanism 7 is also provided at the connection between the discharge hopper 6 and the feed hopper 5.
[0019] like Figures 2 to 4 As shown, the mixing mechanism 7 includes a mixing rod 71 that is connected to the discharge hopper 6 and close to the feed hopper 5. Bearings are fixed on both sides of the discharge hopper 6. The two ends of the mixing rod 71 are respectively mounted on the two bearings. The two ends of the mixing rod 71 extend through to both sides of the discharge hopper 6. The pushing mechanism 8 includes first connecting rods 81 located on both sides of the discharge hopper 6 and respectively fixed to the two ends of the mixing rod 71. The pushing mechanism 8 also includes long rods 82 located on both sides of the discharge hopper 6. The middle of the two long rods 82 are respectively connected to the two first connecting rods 81 through hinges. One end of the two long rods 82 extends toward the discharge end of the discharge hopper 6 and is connected to a push plate 83. The other end of the long rods 82 extends toward the discharge end of the feed hopper 5 and is connected to a second connecting rod 84 through hinges. A motor 10 is fixed on the feed hopper 5. The actuation shaft of the motor 10 is connected to the second connecting rod 84.
[0020] Therefore, when the material flows from the inclined plane 16 between the feed hopper 5 and the discharge hopper 6 to the discharge hopper 6, the material will temporarily stop under the action of the horizontal state of the discharge hopper 6. The actuating shaft of the motor 10 rotates, driving the second connecting rod 84 to rotate. The second connecting rod 84 drives the long rod 82 to complete the forward and backward and up and down swinging movements in the feed and discharge direction of the discharge hopper 6. The long rod 82 drives the first connecting rod 81 to complete the rotational swinging movement in the feed and discharge direction of the discharge hopper 6. The motion trajectory of the long rod 82 will drive the push plate 83 at the front end. Intermittent pushing action is performed at the discharge end of the discharge hopper 6. That is, the pusher plate 83 is first lifted upward, and then retreats from the discharge port of the discharge hopper 6 back to the storage area. Then it plunges into the temporarily stored material. When the long rod 82 moves towards the discharge port of the discharge hopper 6 again, the pusher plate 83 pushes some material from the temporarily stored material into the high-temperature furnace 3. This achieves the purpose of feeding the material remaining in the discharge hopper 6 into the high-temperature furnace 3 in stages, thus solving the problem of excessive feeding at one time, which affects the melting efficiency of the high-temperature furnace 3.
[0021] In this embodiment, a long rod 82 is used as the power component for the pusher plate 83 to complete the above-mentioned actions. This separates the pushing area of the pusher plate 83 from the temporary storage area of the material on the discharge hopper 6 by a considerable distance. As a result, when the pusher plate 83 feeds the material into the high-temperature furnace 3, it not only improves the melting efficiency but also ensures a greater distance between the furnace opening and the material storage area on the discharge hopper 6. This prevents the material in the temporary storage area from melting and solidifying on the discharge hopper 6 due to the high temperature at the furnace opening, thus avoiding inconvenience in discharging. At the same time, using a long rod 82 for long-distance operation also allows the motor 10 to be installed in a safer position.
[0022] In addition, driven by the rotation of the first connecting rod 81, the stirring rod 71 can also complete the stirring action in the discharge hopper 6. Since the stirring mechanism 7 also includes the material teeth 72 arranged on the stirring rod 71 along its length, when the long rod 82 moves forward, backward, and swings in the infeed and discharge direction of the discharge hopper 6, it will also use the first connecting rod 81 to rotate the stirring rod 71. The stirring rod 71 will also rotate once in the forward and reverse directions in the discharge hopper 6 along with the material teeth 72. Every time the first connecting rod 81 swings left and right, it will cause the stirring rod 71 to rotate. The stirring rod 71 rotates left and right once inside the discharge hopper 6. Since the stirring rod 71 is located inside the discharge hopper 6, and the material flowing into the discharge hopper 6 for temporary storage is also located in the same area as the stirring rod 71, the presence of the stirring rod 71 and the material teeth 72 plays three roles for the material. The first role is to partially intercept the material flowing into this area of the discharge hopper 6 (some material will still flow directly from the bottom of the material teeth 72 to the discharge side of the stirring rod 71), preventing the material from flowing directly into the high-temperature furnace 3 due to excessive flow velocity when entering the discharge hopper 6. The second role is that when the stirring rod 71 rotates with the material teeth 72, it can also bring the intercepted material from the feed side of the stirring rod 71 to the discharge side of the stirring rod 71. The third function is to achieve secondary mixing of the material in the discharge hopper 6 under the stirring action of the stirring rod 71 and the material teeth 72, so that the components such as quartz sand, alkali, and lime powder that make up the material are fully mixed for the second time and then sent to the discharge side of the stirring rod 71. After being pushed by the pusher plate 83, it is put into the high-temperature furnace 3 for melting treatment, so as to improve the quality of the melt. The quality of the cooled glass sand is also improved.
[0023] like Figure 1 As shown, a baffle 11 is fixed to the top of the discharge hopper 6. The baffle 11 covers the top of the stirring rod 71 and also covers the material teeth 72 on the stirring rod 71 inside the discharge hopper 6. The baffle 11 prevents the material stirred up by the material teeth 72 from falling down from the top of the discharge hopper 6 when it is stirring.
[0024] like Figure 1 As shown, in order to improve the pushing effect and increase the pushing efficiency, the pusher plate 83 has a pushing cavity 831 on the side (pushing surface) facing away from the stirring rod 71.
[0025] like Figure 3 , Figure 4 As shown, several diversion plates 722 are provided on the surface of the material tooth 72 along its length direction. The diversion plates 722 are wavy. Each wavy profile of the diversion plate 722 passes through each groove 721 on the diversion plate 722. There are several material teeth 72. The several material teeth 72 are fixed on the stirring rod 71 in a circular array. Each material tooth 72 has a row of grooves 721.
[0026] As the material teeth 72 rotate with the stirring rod 71, they agitate the material. The material is distributed along the wave trajectory surface of the diverter plate 72 on the material teeth 72. As the material is distributed along the wave trajectory surface of the diverter plate 722, its components are mixed again. After the material is mixed, it falls down along the trough 721 as the material teeth 72 rotate with the stirring rod 71. Some of the material remains on the feed side of the stirring rod 71 after falling through the trough 721, waiting to be mixed again after the next stirring or the next piece of material teeth 72. Some of the material is pushed to the discharge side of the stirring rod 71 by the effective surface of the material teeth 72, and is pushed by the pusher plate 83.
[0027] like Figures 3 to 6 As shown, a lifting plate 12 is provided inside the discharge hopper 6. One end of the lifting plate 12 extends to the feed side near the push plate 83, and the other end of the lifting plate 12 is close to the bottom of the material teeth 72. The end of the lifting plate 12 near the feed side of the push plate 83 gradually tilts downward and is movably connected to the discharge hopper 6 by means of a transfer. The end of the lifting plate 12 near the bottom of the material teeth 72 gradually tilts upward, and a spring 13 is connected to the bottom surface of the tilted end of the lifting plate 12. The bottom end of the spring 13 is elastically connected to the bottom surface of the inner cavity of the discharge hopper 6. A wheel 14 is installed at one end of the stirring rod 71. The wheel 14 is located inside the discharge hopper 6. The bottom of the wheel 14 is close to the top of the raised end of the lifting plate 12. A roller 15 is fixed on the wheel 14 and can roll and contact the top surface of the raised end of the lifting plate 12 when it rotates. When the roller 15 rotates with the wheel 14 and contacts the top surface of the raised end of the lifting plate 12, the lifting plate 12 can rotate downward around the rotating shaft 17. When the roller 15 rotates with the wheel 14 and separates from the top surface of the raised end of the lifting plate 12, the lifting plate 12 rotates upward under the support of the spring 13. A tape 9 is connected between the bottom surface of the raised end of the lifting plate 12 and the bottom surface of the inner cavity of the discharge hopper 6.
[0028] When the material is fed from the feed side of the stirring rod 71 to the discharge side of the stirring rod 71 by the material teeth 72, in addition to mixing the material components, the stirring rod 71 also drives the wheel 14 to rotate. When the wheel 14 rotates until its roller 15 contacts the top surface of the raised end of the lifting plate 12 and then quickly separates, the lifting plate 12 completes one vibration action. That is, after the lifting plate 12 rotates downward, it rotates upward and resets under the support of the spring 13. Since the raised end of the lifting plate 12 is located on the discharge side of the stirring rod 71, the material will fall onto the lifting plate 12 when it is agitated and transferred by the material teeth 72 on the stirring rod 71. Under the vibration action of the lifting plate 12, the material reaches the pushing area of the push plate 83. This avoids the material teeth 72 from bringing the material back when rotating to the discharge side of the stirring rod 71, which would cause the push plate 83 to push without load. The structure is reasonable.
