Description

Technical Field

[0001] This invention relates to the field of mineral powder storage equipment technology, specifically to an active mineral powder storage device. Background Technology

[0002] Activated particulate (mixed) mineral powder is a product obtained by pulverizing and refining minerals (such as calcium carbonate and clay) and activating them with coupling agents. Activated mineral powder storage equipment requires comprehensive consideration of multiple factors, including the physical and chemical properties of the mineral powder, storage capacity, moisture and dust protection requirements, ease of transportation and unloading, safety, and environmental protection requirements.

[0003] While existing activated mineral powder storage equipment can meet the physical and chemical properties, safety, and environmental protection requirements of mineral powder, the generally large size of these equipment means that some storage units may have insufficient capacity after repackaging the same batch of similar mineral powder. Furthermore, they cannot be mixed with different batches and types of mineral powder. If there are many different batches and types of mineral powder, the demand for storage equipment will increase, leading to inefficient use of the equipment. Therefore, there is an urgent need for an activated mineral powder storage device to solve these problems. Summary of the Invention

[0004] This invention provides an active mineral powder storage device to solve problems in the mineral powder storage process of related technologies.

[0005] This invention provides an active mineral powder storage device, including a mineral powder storage tank. The mineral powder storage tank is a cylindrical structure with an upward-opening shape. Multiple supports are welded circumferentially to the outer side of the storage tank near the bottom. A feeding hopper is detachably connected to the bottom of the storage tank, and a feeding port is opened at the bottom of the feeding hopper. A central fixing column is fixedly connected to the center of the bottom of the storage tank. A lid is provided on the top of the storage tank, and an annular groove is opened at the bottom of the lid. The annular groove engages with the top of the storage tank, and the lid is slidably connected to the central fixing column. The bottom end is provided with a feed inlet; there are two fixed partitions, which are symmetrically fixed to both sides of the central fixed column, dividing the mineral powder storage tank into two equal parts. There are two placement slots in the middle of each fixed partition, and a rotation drive assembly is installed in the placement slot. The upper end of the two placement slots is connected to a cover plate, which is connected to the top of the fixed partition by bolts and threads; there are two rotating partitions, which are rotatably connected to the central fixed column by rotating rings fixed to the rotating partitions, and the rotating rings rotate through the clearance slots opened near the central fixed column in the fixed partitions.

[0006] In one possible implementation, the rotation drive assembly includes a reversible motor fixedly connected to the placement slot via a motor mount. The bottom output shaft of the reversible motor is fixedly connected to a rotating shaft, and the other end of the rotating shaft is rotatably connected to the bottom of the placement slot. Two steel wire ropes are wound on the rotating shaft. A through slot is provided on the placement slot near the outer side, and an annular rubber ring is fixedly adhered to the through slot. The inner ring of the annular rubber ring is tightly fitted to the steel wire ropes.

[0007] In one possible implementation, the two steel wire ropes pass through a through groove and are connected to a rotating partition on an adjacent side. A hanging ring is fixedly welded to the side of the rotating partition closest to the fixed partition, corresponding to the position of the steel wire rope. The steel wire rope is fixedly welded to the corresponding hanging ring.

[0008] In one possible implementation, a rectangular groove is formed at the center of the bottom end of the rotating partition, and multiple steel balls are evenly rolled and connected in the rectangular groove. A first rubber strip is fixedly bonded to the bottom end of the rotating partition and on both sides of the steel balls, and a second rubber strip is also fixedly bonded to the side of the rotating partition near the inner wall of the mineral powder storage tank.

[0009] In one possible implementation, an adjustable isolation assembly is also included. The adjustable isolation assembly is located below the lid and consists of four sets, which are respectively arranged between adjacent fixed partitions and rotating partitions, and slide up and down between the fixed partitions and rotating partitions.

[0010] In one possible implementation, the adjusting isolation assembly includes sliding grooves respectively formed on adjacent sides of a fixed partition and a rotating partition. Each of the fixed partition and the rotating partition has two sliding grooves on its side. An electric slider is disposed in one sliding groove, and a slider is slidably disposed in the other sliding groove. A support rod is fixedly connected to the upper end of both the electric slider and the slider.

[0011] In one possible implementation, support rods on the same side of the same fixed partition are connected to a first fixed block, and support rods on the same side of the same rotating partition are connected to a second fixed block. The side of the second fixed block closest to the central fixed column is rotatably connected to the middle of the first fixed block via a rotating shaft. In the same set of adjusting isolation components, the side of the first fixed block closest to the second fixed block has a receiving groove. The thickness of the second fixed block is less than the height of the receiving groove. When the second fixed block rotates, it can rotate into the receiving groove. An isolation cloth is connected between the first fixed block and the second fixed block.

[0012] In one possible implementation, the isolation cloth is fully expanded into a fan-shaped structure. The side of the isolation cloth near the first fixing block is fixedly bonded to the receiving groove, and the side of the isolation cloth near the second fixing block is fixedly bonded to the second fixing block. Multiple arc-shaped grooves are provided in the middle of the isolation cloth. Connecting grooves are provided on the side of the first and second fixing blocks near the isolation cloth. Tension springs are connected in the arc-shaped grooves. The tension springs are fixedly connected to the isolation cloth at intervals by steel wire rope clamps. The two ends of the tension springs are respectively fixed in the connecting grooves.

[0013] In one possible implementation, the central fixing column is a hollow cylindrical structure, the height of the central fixing column is higher than the height of the mineral powder storage tank, and a heating resistance wire is installed inside the central fixing column. A sealing plug is snapped into the top of the central fixing column, and a hanging ring is fixedly connected to the top of the sealing plug.

[0014] In one possible implementation, the feed inlets are provided in four sets, which are evenly distributed at the bottom of the mineral powder storage tank. Each set has two feed inlets, one of which is located near the side of the fixed partition. Each feed inlet is equipped with an electric valve.

[0028] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Please see Figure 1 , Figure 2 and Figure 4 An active mineral powder storage device includes a mineral powder storage tank 1, which is a cylindrical structure with its opening facing upwards. Multiple supports are welded circumferentially to the outer side of the storage tank 1 near its bottom. A feeding transition hopper 2 is detachably connected to the bottom of the storage tank 1, and a feeding port 21 is provided at the bottom of the feeding transition hopper 2. A central fixing column 11 is fixedly connected to the center of the bottom of the storage tank 1. A lid 12 is provided on the top of the storage tank 1, and an annular groove 121 is provided at the bottom of the lid 12. The annular groove 121 engages with the top of the storage tank 1, and the lid 12... The mineral powder storage tank 1 is slidably connected to the central fixed column 11, and a feed inlet 13 is provided at the bottom end. Two fixed partitions 3 are provided and symmetrically fixed to both sides of the central fixed column 11, dividing the inside of the mineral powder storage tank 1 into two equal parts. Two placement slots 31 are provided in the middle of each fixed partition 3. A rotation drive assembly 32 is provided in the placement slot 31. A cover plate 33 is snapped into the upper end of the two placement slots 31. The cover plate 33 is connected to the top of the fixed partition 3 by bolt thread.

[0030] Continue reading Figure 6 Two rotating partitions 4 are provided, both of which are rotatably connected to the central fixed column 11 by rotating rings 41 fixedly connected to the rotating partitions 4. The rotating rings 41 rotate through the clearance groove opened near the central fixed column 11 in the fixed partition 3.

[0031] The mineral powder storage tank 1 is fixed to the work site by multiple supports. In the prior art, a staircase is provided on the outside of the mineral powder storage tank 1 to facilitate workers to inspect or perform other work on the mineral powder storage tank 1. This is not shown in the figure. In practical applications, the existing staircase can be welded to the outer wall of the mineral powder storage tank 1 to facilitate subsequent operations. The fixed partition 3 divides the inner cavity of the mineral powder storage tank 1 into two equal chambers. The rotating partition 4 is rotatably connected to the two chambers respectively, which can divide the inner cavity of the mineral powder storage tank 1 into four chambers of different capacities. Different mineral powders or different batches of mineral powder can be stored in different chambers. The mineral powder in different chambers flows into the feeding transition hopper 2 for centralized feeding by opening the corresponding feed port 13.

[0032] There are four sets of feed inlets 13, which are evenly distributed at the bottom of the mineral powder storage tank 1. Each set has two inlets, one of which is close to the side of the fixed partition 3. Each feed inlet 13 is equipped with an electric valve.

[0033] When the rotating partition 4 is set at a 90-degree angle to the adjacent fixed partition 3, that is, when the inner cavity of the mineral powder storage tank 1 is divided into four equal parts, each of the four cavities contains a set of feed inlets 13. Two feed inlets 13 in the same set are positioned such that one is near the side of the fixed partition 3 and the other is near the side of the rotating partition 4. When the rotating partition 4 rotates, the cavity formed by the rotating partition 4 and the fixed partition 3 contains at least one feed inlet 13 and at most three feed inlets 13 on the fixed partition. This allows the mineral powder stored between the fixed partition 3 and the rotating partition 4 to fall into the feed transition hopper 2 through the feed inlets 13. The feed transition hopper 2 is designed to buffer the feeding speed and, when more than two feed inlets 13 simultaneously feed the same type of mineral powder, it can be collected first and then fed in a concentrated manner.

[0034] See Figure 2 and Figure 5 The rotation drive assembly 32 includes a forward and reverse motor 321 fixedly connected to the placement groove 31 via a motor base. The bottom output shaft of the forward and reverse motor 321 is fixedly connected to a rotating shaft 322. The other end of the rotating shaft 322 is rotatably connected to the bottom of the placement groove 31. Two steel wire ropes 323 are wound around the rotating shaft 322. A through groove 324 is provided on the placement groove 31 near the outer side. The two steel wire ropes 323 pass through the through groove 324 and are connected to the rotating partition 4 on the adjacent side. A hanging ring is fixedly welded to the side of the rotating partition 4 near the fixed partition 3, corresponding to the position of the steel wire rope 323. The steel wire rope 323 is fixedly welded to the corresponding hanging ring. An annular rubber ring 325 is fixedly adhered to the through groove 324. The inner ring of the annular rubber ring 325 is set tightly against the steel wire rope 323.

[0035] The rotation drive assembly 32 is configured to pull the rotating partitions 4 on both sides to adjust the size of the inner cavity of the mineral powder storage tank 1. It starts the reversible motor 321 on one of the fixed partitions 3, which drives the rotation around the shaft 322. Simultaneously, the shaft drives two steel wire ropes 323 to pull the rotating partition 4 to the side being pulled. The two steel wire ropes 323 are connected to the middle of the rotating partition 4 for force balance and ease of pulling. At the same time, the reversible motor 321 on the other fixed partition 3 rotates in the opposite direction to the side pulling the rotating partition 4, releasing the corresponding steel wire rope 323 around the shaft 322 during the pulling process. The two reversible motors 321 work together to pull the rotating partition 4.

[0036] See Figure 3 , Figure 4 and Figure 5 A rectangular groove 42 is provided in the middle of the bottom of the rotating partition 4. Multiple steel balls 43 are evenly rolled and connected in the rectangular groove 42. A first rubber strip 44 is fixedly bonded to the bottom of the rotating partition 4 and on both sides of the steel balls 43. A second rubber strip 45 is also fixedly bonded to the side of the rotating partition 4 near the inner wall of the mineral powder storage tank 1.

[0037] The steel ball 43 is set in the rotating partition 4 to reduce the friction with the bottom of the mineral powder storage tank 1 during the rotation process, so as to facilitate the pulling of the rotating partition 4. At the same time, the first rubber strip 44 on both sides plays a sealing role on the rectangular groove 42 to prevent the mineral powder in different cavities from mixing. The second rubber strip 45 also increases the sealing between the rotating partition 4 and the inner wall of the mineral powder storage tank 1.

[0038] See Figure 1 and Figure 5 The central fixing column 11 is a hollow cylindrical structure. The height of the central fixing column 11 is higher than the height of the mineral powder storage tank 1. A heating resistance wire 111 is installed inside the central fixing column 11. A sealing plug 112 is snapped into the top of the central fixing column 11. A hanging ring is fixedly connected to the top of the sealing plug 112.

[0039] The heating resistance wire 111 can heat the cavity of the mineral powder storage tank 1 in a timely manner under low temperature conditions. The sealing plug 112 can be opened under external force to avoid excessive pressure inside the central fixed column 11 when the heating temperature is too high.

[0040] participate Figure 4 and Figure 7 The active mineral powder storage equipment also includes an adjusting isolation component 5, which is located below the lid 12. Four sets of the adjusting isolation component 5 are provided, each set positioned between adjacent fixed partitions 3 and rotating partitions 4, and slide vertically between them. The adjusting isolation component 5 includes sliding grooves 51 respectively formed on adjacent sides of the fixed partitions 3 and rotating partitions 4. Two sliding grooves 51 are formed on the sides of each of the three fixed partitions and the rotating partitions 4. An electric slider 52 is installed in one sliding groove 51, and a slider 53 is slidably installed in the other sliding groove 51. Support rods 54 are fixedly connected to the upper ends of both the electric slider 52 and the slider 53.

[0041] It should be noted that since the two fixed partitions 3 are fixed inside the mineral powder storage tank 1, the electric slider 52 is set on the fixed partitions 3 to facilitate electrical connection to external circuits. This is existing technology and is not shown in the figure, so it will not be described in detail here.

[0042] The purpose of adjusting the isolation component 5 is to seal the upper end of the cavity containing mineral powder in a timely manner, isolate it from the air, prevent the mineral powder inside from being affected by air and dust, keep the mineral powder dry and pure, prevent moisture absorption and agglomeration, and reduce the impact of dust when other mineral powders are fed in.

[0043] See Figure 4 and Figure 7Support rods 54 on the same side of the same fixed partition 3 are connected to a first fixed block 55. Support rods 54 on the same side of the same rotating partition 4 are connected to a second fixed block 56. The side of the second fixed block 56 closest to the central fixed column 11 is rotatably connected to the middle of the first fixed block 55 via a rotating shaft. In the same set of adjusting isolation components 5, the side of the first fixed block 55 closest to the second fixed block 56 has a receiving groove 551. The thickness of the second fixed block 56 is less than the height of the receiving groove 551. When the second fixed block 56 rotates, it can rotate into the receiving groove 551. An isolation cloth 57 is connected between the first fixed block 55 and the second fixed block 56.

[0044] Specifically, the two electric sliders 52 on the same set of adjusting isolation components 5 are activated simultaneously. The two electric sliders 52 synchronously drive the support rod 54 to slide up and down. Under the action of the first fixed block 55 and the second fixed block 56, the slider 53 will also slide up and down synchronously. The first fixed block 55 and the second fixed block 56 will synchronously drive the middle isolation cloth 57 to move up and down synchronously.

[0045] Continue reading Figure 7 and Figure 8 The isolation cloth 57 is fully expanded into a fan-shaped structure. The side of the isolation cloth 57 near the first fixing block 55 is fixedly bonded to the receiving groove 551. The side of the isolation cloth 57 near the second fixing block 56 is fixedly bonded to the second fixing block 56. Multiple arc-shaped grooves 571 are provided in the middle of the isolation cloth 57. The first fixing block 55 and the second fixing block 56 are both provided with connecting grooves on the side near the isolation cloth 57. Tension springs 572 are connected in the arc-shaped grooves 571. Tension springs 572 are fixedly connected to the isolation cloth 57 at intervals through wire rope clamps 573. The two ends of the tension springs 572 are respectively fixed in the connecting grooves.

[0046] To ensure the folding and air-isolation functions of the tension spring 572, the tension spring 572 can be made of aerogel, ceramic fiber cloth, or glass fiber cloth. It can be folded arbitrarily, can isolate air, and can withstand high temperatures.

[0047] While rotating the partition 4, the first fixed block 55 will move towards the second fixed block 56. Since the isolation cloth 57 is fully opened into a fan-shaped structure, greater than 90 degrees and less than 180 degrees, the angle formed between the adjacent fixed partition 3 and the rotating partition 4 is always less than 180 degrees. A part of the isolation cloth 57 will be folded into the receiving groove 551 under the action of the tension spring 572. The part of the isolation cloth 57 located between the first fixed block 55 and the second fixed block 56 is also not fully opened and is folded. It should be noted that the folded shape is not shown in the figure. Adjust the isolation component 5 and the lowest height of the isolation cloth 57 can be slid to the upper end of the upper steel wire rope 323. The highest height of the isolation cloth 57 can be slid to the top of the mineral powder storage tank 1 to facilitate the feeding of materials. When the first fixing block 55 and the second fixing block 56 form the minimum angle, both the isolation cloth 57 and the second fixing block 56 can rotate into the interior of the receiving groove 551 under the action of the tension spring 572. Since the fixed partition 3 and the rotating partition 4 form the minimum cavity, there is still space at the bottom feed port 13 of the mineral powder storage tank 1. In this case, the end of the second fixing block 56 near the inner wall of the mineral powder storage tank 1 is still outside the receiving groove 551.
