Description

Technical Field

[0001] This invention belongs to the field of refractory material conveying technology, and specifically relates to a quantitative conveying device for refractory material raw materials. Background Technology

[0002] In the production of refractory materials, the quantitative transportation of raw materials is a crucial link in ensuring the stability of the production process and the quality of the products. As the core equipment for achieving precise delivery of raw materials, the performance of the refractory material raw material conveying device directly affects the accuracy of raw material proportioning and production efficiency in subsequent processes, and is a key foundation for ensuring that the various technical indicators of refractory material products meet the standards.

[0003] Existing refractory material conveying devices mainly consist of a hoist and a storage silo. The storage silo is mounted on the hoist, which also has a discharge pipe connected to the bottom of the storage silo. A valve is installed on the discharge pipe. In practical use, the refractory material is first loaded into the storage silo. The hoist is then moved to a predetermined position, and the valve on the discharge pipe is opened. The refractory material is then discharged under gravity and conveyed to the subsequent production station.

[0004] However, in practical use, refractory raw materials tend to adhere to the inner wall of the storage silo. With increasing usage time, this adhered material gradually accumulates, not only wasting raw materials but also causing deviations between the actual output and the predetermined quantitative standard. This affects the accuracy of raw material proportioning in subsequent production, ultimately negatively impacting product quality. Furthermore, the material handling equipment typically only has one discharge pipe for unloading. This single discharge channel leads to concentrated material falling during unloading, causing the unloaded material to accumulate in one place, making even distribution difficult. Moreover, because the material passes through the discharge pipe in a concentrated manner, blockages are easily formed inside the pipe and at the discharge port. Once a blockage occurs, operators must stop the machine for cleaning and unblocking, which not only increases labor intensity but also causes production interruptions, severely reducing unloading efficiency and failing to meet the demands of modern refractory material production for efficient and continuous operation. Summary of the Invention

[0005] This invention addresses the problems of deviations in the output of existing material conveying devices and the tendency to clog, by providing a quantitative material conveying device for refractory materials that can achieve quantitative output and is less prone to clogging.

[0006] To solve the above problems, the technical solution adopted by the present invention is a quantitative conveying device for refractory raw materials, including an automatic guide car, a lifting plate on the automatic guide car, a base plate fixed to the top of the lifting plate, a weighing storage bin fixed to the base plate, a weighing sensor inside the weighing storage bin, a feed pipe connected to the top of the weighing storage bin, a cleaning mechanism inside the weighing storage bin that can remove refractory raw materials adhering to the side wall of the weighing storage bin, a discharge pipe connected to the bottom of the weighing storage bin, and a discharge mechanism below the discharge pipe that can disperse and discharge the refractory raw materials discharged from the discharge pipe.

[0007] In this technical solution, refractory raw materials are loaded into a weighing silo via a feed pipe. Weighing sensors inside the silo monitor weight changes in real time to achieve quantitative loading. An automated guided vehicle then transports the silo to a predetermined location, and the refractory raw materials are discharged through a discharge pipe. During discharge, a cleaning mechanism removes refractory raw materials adhering to the side walls of the silo, ensuring complete discharge of the measured quantity. A discharging mechanism disperses the discharged refractory raw materials from the discharge pipe, preventing accumulation and blockage. Therefore, this device not only achieves quantitative discharge of refractory raw materials but also maintains smooth discharge without clogging, effectively improving operational efficiency.

[0008] Furthermore, the cleaning mechanism includes a housing fixed to the top wall of the weighing storage silo. The housing is annular, with its axis coinciding with the axis of the weighing storage silo. The inner diameter of the housing is larger than the diameter of the feed pipe. An annular cavity is formed inside the housing, and an annular groove is formed at the bottom of the housing. The centerline of the annular groove coincides with the axis of the housing. A connecting rod is installed inside the annular groove. The upper end of the connecting rod is connected to a drive assembly, which controls the connecting rod to move circumferentially around the centerline of the annular groove. A cleaning brush is fixed to the lower end of the connecting rod. The inner diameter of the housing is larger than the diameter of the feed pipe, ensuring that the refractory material entering from the feed pipe can pass through the inner diameter of the housing without obstruction, avoiding interference with the feeding process. The drive assembly can control the connecting rod to move in a circle around the center line of the annular groove. This movement can drive the cleaning brush fixed at the lower end of the connecting rod to make a 360-degree circular motion along the side wall of the weighing storage bin, thereby ensuring that the cleaning brush can fully cover the side wall area of ​​the weighing storage bin. During the circumferential movement, the cleaning brush can effectively brush off the refractory material raw materials adhering to the side wall of the weighing storage bin through the mechanical action of the bristles.

[0009] Furthermore, the drive assembly includes a meshing gear ring and a gear, both disposed inside the cavity. The inner wall of the gear ring fits against the inner sidewall of the cavity. The upper end face of the gear is fixedly connected to the output shaft of the first motor, which is fixed to the top of the weighing storage hopper. The lower end face of the gear ring is fixedly connected to the upper end of the connecting rod. The drive assembly, comprising a meshing gear ring and a gear, both disposed inside the cavity, with the inner wall of the gear ring fitting against the inner sidewall of the cavity, provides a stable meshing support reference for the gear. This ensures that the gear ring and gear maintain precise meshing during transmission, preventing transmission failure due to shaking or misalignment, and guaranteeing the smoothness and accuracy of motion transmission.

[0010] Furthermore, the shape of the cleaning brush matches the contour of the side wall of the weighing silo, and the bristles of the cleaning brush fit snugly against the side wall of the weighing silo. Cleaning teeth are fixed to the side wall of the weighing silo, the height of which is adapted to the cleaning brush, and the cleaning teeth are comb-shaped. The matching shape of the cleaning brush to the side wall contour of the weighing silo, and the close fit between the bristles and the side wall, ensures that the cleaning brush closely adheres to the side wall surface during rotation, covering the side wall area without dead angles, effectively removing refractory material adhering to the side wall, and avoiding blind spots or residues caused by loose fit. Each rotation of the cleaning brush causes the cleaning teeth to scrape the bristles, utilizing the elastic deformation principle of the bristles to generate high-frequency vibrations, which shakes off fine refractory material embedded in the bristles, preventing refractory material residue from remaining on the cleaning brush.

[0011] Furthermore, the unloading mechanism includes a dispersing component and a clearing component. The dispersing component is located below the feeding pipe and disperses the refractory material discharged from the feeding pipe to below the automated guided vehicle (AGV). The clearing component is located inside the feeding pipe and clears any refractory material blockages within the feeding pipe. The dispersing component evenly distributes the refractory material discharged from the feeding pipe to below the AGV, ensuring a wider distribution range and lower accumulation height. This not only facilitates subsequent transport by the AGV or processing in downstream processes but also reduces problems such as excessive local pressure and agglomeration caused by concentrated accumulation of refractory material. The clearing component, located inside the feeding pipe, allows for timely mechanical intervention when blockages occur, clearing blockages without machine shutdown or manual intervention. This significantly reduces production downtime caused by blockages and improves the continuity and automation of the unloading process.

[0012] Furthermore, the dispersion component includes a horizontally arranged conveyor cylinder located below and connected to the discharge pipe. A baffle plate is fixed inside the conveyor cylinder, positioned below the discharge pipe, with its top shaped like an inverted V. Two discharge pipes are connected to the side wall of the conveyor cylinder, located on opposite sides of the baffle plate. The inverted V-shape of the baffle plate guides and diverts the refractory material discharged from the discharge pipe to both sides, preventing the refractory material from accumulating in the middle of the conveyor cylinder. The two discharge pipes, connected to the side wall of the conveyor cylinder and located on opposite sides of the baffle plate, work in conjunction with the diversion effect of the inverted V-shaped baffle plate to divert the refractory material discharged from the discharge pipe to both sides via the top of the baffle plate, and then discharge it through the two discharge pipes. This achieves symmetrical and dispersed unloading of the refractory material, avoiding localized accumulation or uneven unloading caused by a single discharge point.

[0013] Furthermore, the dispersion assembly also includes a second motor, which is fixed to the end of the conveying cylinder. The output shaft of the second motor is fixedly connected to one end of the first spiral shaft, and the other end of the first spiral shaft passes through the partition and is fixedly connected to one end of the second spiral shaft. A first spiral blade is fixed to the outer wall of the first spiral shaft, and a second spiral blade is fixed to the outer wall of the second spiral shaft. The spiral direction of the second spiral blade is opposite to that of the first spiral blade. The first spiral shaft has a first spiral blade fixed to its outer wall, and the second spiral shaft has a second spiral blade with the opposite spiral direction fixed to its outer wall. The first spiral shaft passes through the partition and is connected to the second spiral shaft. When the second motor drives the first spiral shaft to rotate, the first and second spiral blades with the opposite spiral directions can respectively convey the refractory material raw materials on both sides of the partition to both ends of the conveying cylinder. Through the mechanical action of the bidirectional spiral, the refractory material raw materials are forcibly dispersed. Compared with passive dispersion relying solely on gravity, this method can more efficiently break up clumps or accumulations of refractory material raw materials, ensuring a uniform distribution of the refractory material raw materials.

[0014] Furthermore, the unblocking component includes a cam located below the partition and fixed to the outer wall of the first spiral shaft. A connecting wheel is positioned above the cam, with its outer cylindrical surface rolling in contact with the working contour of the cam. A rotating rod is located inside the connecting wheel, with its end rotatably connected to a fixed block. The fixed block is fixedly connected to the lower end of a support rod, and the upper end of the support rod penetrates the partition and is fixed with an unblocking rod located inside the feed pipe. The working contour of the cam rolls in contact with the outer cylindrical surface of the connecting wheel, converting the circular motion of the first spiral shaft into the reciprocating lifting motion of the connecting wheel through the cam mechanism. This, in turn, drives the unblocking rod to move synchronously up and down inside the feed pipe via the rotating rod and the support rod. Located inside the feed pipe, the unblocking rod, when moving up and down with the support rod, can mechanically intervene in the reciprocating motion of refractory material adhering to or accumulating on the inner wall of the feed pipe. It is particularly effective against blockages caused by particle agglomeration, adhesive adhesion, or bridging effects, effectively disrupting the blockage structure and ensuring the smooth flow of refractory material.

[0015] Furthermore, the unblocking rod is designed in a cross shape, with a conical protrusion fixed to its top. The cross shape allows the four arm-like structures to fully contact the inner wall of the discharge pipe during its vertical movement, ensuring thorough unblocking of refractory material blockages around the circumference of the discharge pipe and avoiding blind spots caused by a single rod. The conical protrusion at the top of the rod effectively inserts into clumps or arches formed by the refractory material, using the conical inclined surface to disperse or break up the blockage, reducing its strength and integrity, making it easier for the refractory material to fall and be discharged, thus improving unblocking efficiency.

[0016] Furthermore, fixing rods are fixed to both sides of the fixing block, and connecting blocks are fixed to the fixing rods. A sliding rod penetrating the connecting block is provided on the connecting block. The sliding rod is vertically arranged, with its upper end fixedly connected to the partition plate and its lower end slidably connected to the connecting block. A guide spring is sleeved on the sliding rod, with its upper end fixedly connected to the top of the partition plate and its lower end fixedly connected to the top of the connecting block. The connecting blocks, with their penetrating vertical sliding rods and fixed connections to the partition plate, provide precise vertical guidance for the lifting and lowering movement of the connecting block and support rod, preventing the unblocking rod from shifting due to lateral force during cam drive and ensuring that the unblocking rod always moves up and down along the axis of the discharge pipe. The guide spring sleeved on the sliding rod has its upper end fixed to the top of the partition plate and its lower end fixed to the top of the connecting block, providing elastic buffering when the cam pushes the connecting wheel up and down. The damping effect of the guide spring absorbs the impact force during movement, making the up-and-down reciprocating movement of the connecting wheel smoother.

[0017] As can be seen from the above technical solution, the advantages of this invention are as follows: In this technical solution, refractory raw materials are loaded into a weighing storage silo equipped with a weighing sensor through a feeding pipe, and precise quantitative control is achieved by relying on real-time weight monitoring. After loading is completed, an automated guided vehicle transports the weighing storage silo to a preset workstation, and the refractory raw materials are discharged through a discharge pipe. During this process, a cleaning mechanism removes the refractory raw materials adhering to the side wall of the weighing storage silo, ensuring that the quantitative refractory raw materials are completely discharged; the unloading mechanism disperses the refractory raw materials discharged from the discharge pipe to prevent them from accumulating and clogging the discharge pipe. In summary, this device not only achieves quantitative discharge of refractory raw materials, but also maintains smooth discharge and is not prone to clogging, effectively improving operational efficiency.

Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0022] A refractory material raw material quantitative conveying device, such as Figure 1 , 2 As shown, the system includes an automated guided vehicle (AGV) 1, which is existing equipment equipped with a navigation system and can automatically travel along a predetermined trajectory. An AGV 1 has a support plate 2, the top of which is bolted to a base plate 3. Four support seats 4 are welded to the base plate 3, and the tops of the four support seats 4 collectively support and fix a weighing storage bin 5. A weighing sensor, also existing equipment, is installed inside the weighing storage bin 5 to monitor its internal weight in real time. A feed pipe 6 is connected to the top of the weighing storage bin 5, and the axis of the feed pipe 6 coincides with the axis of the weighing storage bin 5.

[0023] like Figure 3-6 As shown, in this specific embodiment, the cleaning mechanism adopts the following structure: The cleaning mechanism includes a housing 7, which is located inside the weighing storage bin 5, and the top of the housing 7 is fixedly connected to the top wall of the weighing storage bin 5 by welding. The housing 7 is generally annular, with the diameter of its central inner hole being larger than the diameter of the feed pipe 6, and the axis of the housing 7 completely coincides with the axis of the weighing storage bin 5. The housing 7 is a sealed structure, with an annular cavity 31 formed inside it. An annular groove 32 is provided at the bottom of the housing 7, and the center line of the annular groove 32 coincides with the axis of the housing 7. A connecting rod 11 is installed inside the annular groove 32. The upper end of the connecting rod 11 is connected to the drive assembly, which can control the connecting rod 11 to move circumferentially around the center line of the annular groove 32. A cleaning brush 12 is fixedly welded to the lower end of the connecting rod 11.

[0024] The drive assembly includes a vertically arranged first motor 8. The cylinder of the first motor 8 is bolted to the top of the weighing storage silo 5. Its output shaft passes through the top wall of the weighing storage silo 5 and the top of the housing 7, extending into the cavity 31 of the housing 7. The drive assembly also includes a meshing gear ring 10 and a gear 9. Both the gear ring 10 and the gear 9 are disposed in the cavity 31 of the housing 7. The inner wall of the gear ring 10 fits against the inner side wall of the cavity 31. The upper end face of the gear 9 is bolted to the output shaft of the first motor 8, and the lower end face of the gear ring 10 is fixedly connected to the upper end of the connecting rod 11 by welding.

[0025] The cleaning brush 12 is shaped to match the sidewall profile of the weighing storage bin 5. In this embodiment, the cleaning brush 12 is designed as an L-shaped structure, with its upper part fixedly connected to the lower end of the connecting rod 11 by welding. The bristles of the cleaning brush 12 are made of elastic material and fit tightly against the sidewall of the weighing storage bin 5. Comb-shaped cleaning teeth 13 are welded onto the sidewall of the weighing storage bin 5. The cleaning teeth 13 are vertically arranged, and their height is adapted to the size of the cleaning brush 12. Each time the cleaning brush 12 rotates, the teeth of the cleaning teeth 13 scrape against the bristles of the cleaning brush 12.

[0026] like Figure 7 As shown, in this specific embodiment, the unloading mechanism adopts the following structure: the unloading mechanism includes a dispersing component and a clearing component, wherein the dispersing component is located below the feeding pipe 14 and is used to disperse the refractory material raw material discharged from the feeding pipe 14 to the bottom of the automatic guide car 1; the clearing component is located inside the feeding pipe 14 and is used to clear the refractory material raw material blocked in the feeding pipe 14.

[0027] The dispersing assembly includes a horizontally arranged conveyor cylinder 15, with an opening in the base plate 3. The conveyor cylinder 15 is fixed to the opening in the base plate 3 by welding. The conveyor cylinder 15 is located below the discharge pipe 14, and the bottom of the discharge pipe 14 communicates with the side wall of the conveyor cylinder 15. Figure 9 As shown, a baffle 16 is provided inside the conveying cylinder 15, located below the discharge pipe 14, and its surface is coated with a wear-resistant coating. The baffle 16 is generally inverted U-shaped, including two parallel vertical plates, the bottoms of which are fixedly connected to the inner wall of the conveying cylinder 15 by welding. A top plate is provided above the vertical plates, which has an inverted V-shaped structure with a central protrusion. The central protrusion contacts the bottom of the discharge pipe 14, and the two sides of the top plate are welded to the tops of the two vertical plates respectively. The angle between the two sides of the top plate and the horizontal plane of the bottom of the discharge pipe 14 is 45°. Two discharge pipes 30 are connected to the side wall of the conveying cylinder 15, and the two discharge pipes 30 are located on both sides of the baffle 16.

[0028] The dispersing assembly also includes a horizontally arranged second motor 17, the cylinder of which is bolted to the end of the conveying cylinder 15. Its output shaft is fixedly connected to one end of the first spiral shaft 33 via a coupling, and the axis of the first spiral shaft 33 coincides with the axis of the conveying cylinder 15. The other end of the first spiral shaft 33 passes through the partition 16 and is fixedly connected to one end of the second spiral shaft 34 via a coupling. A first spiral blade 18 is welded to the outer wall of the first spiral shaft 33, and a second spiral blade 19 is welded to the outer wall of the second spiral shaft 34, with the rotation direction of the second spiral blade 19 opposite to that of the first spiral blade 18.

[0029] like Figure 8 As shown, the unblocking assembly includes a cam 20, located below the partition 16. The cam 20 is welded to the outer wall of the first spiral shaft 33, and its rotation axis coincides with the axis of the first spiral shaft 33. A cylindrical connecting wheel 21 is provided above the cam 20, and its outer cylindrical surface forms rolling contact with the working contour of the cam 20. A rotating rod 22 is provided inside the connecting wheel 21, and the axis of the rotating rod 22 coincides with the axis of the connecting wheel 21. Fixed blocks 23 are hinged to both ends of the rotating rod 22. Support rods 28 are provided above the two fixed blocks 23. The lower end of the support rod 28 is welded to the top of the fixed block 23, and the upper end of the support rod 28 passes through the top of the partition 16 and is welded to the bottom of the unblocking rod 29. The unblocking rod 29 is located inside the discharge pipe 14 and consists of four mutually perpendicular and horizontally arranged dividing rods, forming a cross-shaped structure. The unblocking rod 29 and the inner wall of the discharge pipe 14 form four symmetrical guide channels. Each of the four dividing rods has a triangular pyramidal conical boss 35 at its top. One side of the conical boss 35 is fixedly connected to the top of the dividing rod. In this embodiment, the dividing rod and the conical boss 35 are integrally formed.

[0030] Two fixing rods 24 are provided on both sides of the connecting wheel 21. There are four fixing rods 24 in total. Two fixing rods 24 are welded to the two sides of one fixing block 23, and the other two fixing rods 24 are welded to the two sides of another fixing block 23. Two connecting blocks 25 are provided on both sides of the connecting wheel 21. The two connecting blocks 25 are welded to the fixing rods 24 on both sides of the connecting wheel 21. That is, the two fixing rods 24 on one side of the connecting wheel 21 are welded to one connecting block 25, and the two fixing rods 24 on the other side of the connecting wheel 21 are welded to another connecting block 25. Each of the two connecting blocks 25 is provided with a sliding rod 26 that passes through the connecting block 25. The sliding rod 26 is slidably connected to the connecting block 25. Both sliding rods 26 are arranged vertically. The lower end of the sliding rod 26 is welded with a stop to prevent the sliding rod 26 from sliding out of the connecting block 25. The upper end of the sliding rod 26 is welded to the partition plate 16. A guide spring 27 is sleeved on the slide rod 26. The guide spring 27 is located between the partition plate 16 and the connecting block 25. The upper end of the guide spring 27 is welded to the top of the partition plate 16, and the lower end of the guide spring 27 is welded to the top of the connecting block 25.

[0031] The specific usage process of this invention is as follows: First, the automatic guided vehicle 1 is controlled to move to the material picking position. Refractory material raw materials enter the weighing storage bin 5 through the feed pipe 6, and the weighing sensor in the weighing storage bin 5 monitors the weight change in real time. When the weight reaches a predetermined value, the loading of refractory material raw materials is stopped. Subsequently, the automatic guided vehicle 1 is controlled to move to the material discharging position, and the valve on the discharge pipe 14 is opened, allowing the refractory material raw materials in the weighing storage bin 5 to fall into the conveying cylinder 15 through the discharge pipe 14.

[0032] After the refractory material falls into the conveying cylinder 15, it is initially diverted by the partition 16, guiding the refractory material to both sides of the partition 16. At this time, the second motor 17 is started, and its output shaft drives the first spiral shaft 33 and the second spiral shaft 34 to rotate synchronously. Since the first spiral blade 18 on the first spiral shaft 33 and the second spiral blade 19 on the second spiral shaft 34 rotate in opposite directions, they respectively convey the refractory material in the conveying cylinder 15 to both ends, so that the refractory material is evenly discharged through the discharge pipes 30 on both sides of the conveying cylinder 15, avoiding accumulation in a single position.

[0033] As the first spiral shaft 33 rotates, the cam 20 fixed to its outer wall rotates synchronously. When the protruding part of the cam 20 moves away from the connecting wheel 21, the connecting wheel 21 loses the thrust of the cam 20 and begins to fall under the action of gravity, causing the rotating rod 22, the fixed block 23, the support rod 28, and the unblocking rod 29 to move downwards synchronously. During this process, the connecting block 25 slides vertically along the slide rod 26, and the guide spring 27 exerts a pulling force on the connecting block 25 to buffer the falling speed and avoid impact caused by rapid movement. When the protruding part of the cam 20 rotates to contact the connecting wheel 21, it begins to push the connecting wheel 21 upwards, causing the rotating rod 22, the fixed block 23, the support rod 28, and the unblocking rod 29 to move upwards synchronously. At this time, the guide spring 27 exerts pressure on the connecting block 25, which also plays a buffering role and prevents rapid ascent. The continuous rotation of the cam 20 causes the unblocking rod 29 to move up and down periodically inside the feed pipe 14, continuously breaking up any accumulation or agglomeration of refractory material inside the pipe, ensuring smooth feeding.

[0034] After most of the refractory material in the weighing silo 5 has been discharged, the first motor 8 is started. Its output shaft drives the gear 9 to rotate, and the gear ring 10 meshing with the gear 9 rotates accordingly, thereby driving the connecting rod 11 and the cleaning brush 12 at its lower end to make circular motions within the weighing silo 5. The bristles of the cleaning brush 12 are in contact with the side wall of the weighing silo 5, and the rotating brush brushes away the refractory material adhering to the side wall of the weighing silo 5. When the cleaning brush 12 rotates to contact the cleaning teeth 13 on the side wall of the weighing silo 5, the comb-like cleaning teeth 13 scrape the bristles, and the elastic deformation of the bristles causes them to vibrate, removing the fine particles remaining on the surface of the bristles and reducing the residue of refractory material in the weighing silo 5.

[0035] As can be seen from the above embodiments, the beneficial effects of the present invention are as follows: In this specific embodiment, refractory raw materials are loaded into a weighing storage silo equipped with a weighing sensor through a feeding pipe, and precise quantitative control is achieved by relying on real-time weight monitoring. After loading is completed, an automated guided vehicle transports the weighing storage silo to a preset workstation, and the refractory raw materials are discharged through a discharge pipe. During this process, a cleaning mechanism removes the refractory raw materials adhering to the side wall of the weighing storage silo, ensuring that the quantitative refractory raw materials are completely discharged; the unloading mechanism disperses the refractory raw materials discharged from the discharge pipe to prevent them from accumulating and clogging the discharge pipe. In summary, this device not only achieves quantitative discharge of refractory raw materials, but also maintains smooth discharge and is not prone to clogging, effectively improving operational efficiency.
