AI Technical Summary
During the preparation of dry ramming materials, the multi-dip requirements lead to the need for multiple quantitative feeders, which increases cost and maintenance difficulty.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of ramming mix preparation, and in particular to a dry ramming mix preparation process. Background Art
[0002] First, when preparing dry ramming mix, it is often necessary to mix powders and aggregates of multiple components, and the mixing process is divided into primary mixing and secondary mixing. First, in primary mixing, fused white corundum fine powder, fused magnesia, activated alumina powder, and titanium dioxide powder are mixed first. In secondary mixing, fused white corundum aggregate and binder are put into the material obtained by mixing fused white corundum fine powder, fused magnesia, activated alumina powder, and titanium dioxide powder for secondary mixing. In the actual production process, in order to meet the use requirements in different scenarios, there are often multiple mixing ratios, and at this time, multiple mixing mechanisms are required for independent processing. However, when processing independently, the following problems occur:
[0003] When preparing dry ramming mix with multiple mixing ratios, first, multiple feeding mechanisms need to be set up. The higher the accuracy of the feeding mechanism, the higher the mixing ratio accuracy. However, when quantitative feeding is carried out in the above manner, each mixing mechanism needs to be equipped with six quantitative feeders. If simultaneous operation is required, assuming there are five mixing mechanisms, then thirty quantitative feeders are required at this time. If high-precision quantitative feeders are selected, the cost is too high, and at the same time, the subsequent maintenance cost also increases greatly;
[0004] If a quantitative feeder is selected to move, there are two problems at this time. First, in order to improve the convenience of feeding, first, the feeder will be equipped with a storage bin, and the mass of the material in the storage bin should be much greater than the required material mass in the mixing tank. Only in this way can the number of material deliveries into the material tank be reduced. Since the power of the motor needs to be able to drive the material tank to move when it is fully stored with materials, when the storage bin is too large, this method is also impractical;
[0005] Therefore, the movement of the feeder can be controlled. At this time, the feeder is more lightweight, and the power of the motor for controlling the movement is not high. However, there is a problem. When the movement distance of the feeder is too long, at this time, the feeder is connected to the material box with a hose. Since the length of the hose needs to meet the requirements from the farthest end to the lowest end, when the feeder is at the nearest end, due to the length of the hose, it will cause the hose to droop and bend downward. Since the material is different from the liquid, the friction between the material and the inner wall of the pipeline is large. At this time, at the nearest end, due to the bending of the pipeline, the material will first fall under the influence of gravity and then rise against the influence of gravity, resulting in the material being unable to reach the position of the quantitative feeder. Therefore, it is necessary to use a pump to transport the material. At this time, six pumps need to work according to the above method, and six hoses are set up at the same time. Therefore, the power consumption still cannot be reduced, and the setting of the hoses also makes the preparation space messy and disorderly. Summary of the Invention
[0006] The object of the present invention is to provide a preparation process for dry ramming mix to solve the problems raised in the above-mentioned background technology.
[0007] To achieve the above object, the present invention provides the following technical solutions:
[0008] A preparation process for dry ramming mix includes:
[0009] S1: Quantitatively and sequentially inject fused white corundum fine powder, fused magnesia, activated alumina powder, and titanium dioxide powder into the cavity of the arc feeding area through a pre-mixing and quantitative feeding mechanism.
[0010] S2: Rotate the mixing tank to the feeding hole at the end of the arc feeding area and wait to obtain the pre-mixed material.
[0011] S3: The fused white corundum fine powder and fused magnesia are closest to the primary mixing mechanism of the pusher. First, they are put in. The primary mixing mechanism of the pusher moves towards the side of the pre-mixing and quantitative feeding mechanism, pushes the fused white corundum fine powder and fused magnesia towards the end of the arc feeding area while mixing the fused white corundum fine powder and fused magnesia. When the primary mixing mechanism of the pusher is close to the feeding points of the activated alumina powder and titanium dioxide powder, the activated alumina powder and titanium dioxide powder are put in through the pre-mixing and quantitative feeding mechanism, and the pre-mixed material composed of the fused white corundum fine powder, fused magnesia, activated alumina powder, and titanium dioxide powder is pushed to the feeding hole of the arc feeding area. At this time, the material enters the mixing tank through the feeding hole for mixing. In this way, until all the mixing tanks obtain the pre-mixed material for mixing;
[0012] S4: Put the fused white corundum aggregate and the binder into the other cavity of the arc feeding area through the secondary mixing and quantitative feeding mechanism.
[0013] S5: The mixing tank continues to rotate in the original rotation direction. At this time, the mixing tank that first put in the pre-mixed material first reaches the feeding hole at the other end of the arc feeding area.
[0014] S6: At this time, the primary mixing mechanism of the pusher rotates in the reverse direction, promotes the mixing of the fused white corundum aggregate and the binder and moves them to the feeding hole at the same time, and enters the inside of the mixing tank. Then, according to the mixing time difference of the mixing tanks, the secondary mixing material is put in. When the secondary mixing material is put into the inside of the mixing tank, the pre-mixed material inside the mixing tank is fully mixed. After all the mixing tanks have put in the secondary materials, at this time, the mixing tank that first put in the secondary materials is located at the initial feeding hole, and the material is taken out. Repeat the steps of S1, S3, S4, S5, and S6 to achieve cyclic preparation.
[0015] As a further solution of the present invention: A rotating disk and a rotating rod are rotatably connected inside the circular bin body. The mixing tanks are annularly distributed on the top of the rotating disk. The arc-shaped feeding area is located above the mixing tanks. The rotating rod is fixedly connected between the rotating rod and the primary mixing mechanism for pushing materials through a driving connecting rod.
[0016] As a further solution of the present invention: The inner wall of the arc-shaped feeding area is provided with arc-shaped tooth grooves. The primary mixing mechanism for pushing materials includes a pushing plate fixed at the center for pushing materials, two mixing tooth disks rotatably connected to the bottom of the primary mixing mechanism for pushing materials. A stirring rod is eccentrically fixedly connected to the mixing tooth disk. A transmission gear is rotatably connected to the bottom of the primary mixing mechanism for pushing materials. The transmission gear is located outside the primary mixing mechanism for pushing materials and inside the arc-shaped tooth grooves. The mixing tooth disk and the transmission gear are connected by a transmission belt for transmission.
[0017] As a further solution of the present invention: An eccentric guiding port is provided at the top of the mixing tank. A mixing motor is installed inside the mixing tank. The mixing motor is located below the eccentric guiding port. The diameter of the top opening of the eccentric guiding port is larger than the diameter of the feeding hole.
[0018] As a further solution of the present invention: Both ends of the arc-shaped feeding area are semi-circular surfaces. The inner diameter of the feeding hole is the same as the inner diameter of the semi-circular surface.
[0019] Compared with the prior art, the beneficial effects of the present invention are:
[0020] Using the arc-shaped feeding area as a unified processing and distribution mechanism for feeding and collecting, the materials are respectively fed through the pre-mixing and quantitative feeding mechanism and the secondary mixing and quantitative feeding mechanism. At this time, the pre-mixing and quantitative feeding mechanism and the secondary mixing and quantitative feeding mechanism are directly fixed at the bottom of the silo. Only the influence of gravity is required to send the materials to the quantitative feeder. At this time, a high-precision quantitative feeder can be used for feeding. After the materials drop to the arc-shaped feeding area, the corresponding mixing tank is switched by rotation until all the pre-mixed materials are fed into the mixing tank for mixing. As the mixing tank rotates to the other end of the arc-shaped feeding area, the mixing tank that first feeds the pre-mixed materials first feeds the secondary mixing materials, and the feeding and mixing are carried out in sequence to realize the preparation of dry ramming materials. This process makes the overall preparation device more compact, the preparation environment space orderly, and at the same time, on the premise of ensuring the high precision of the quantitative feeder, reduces the number of quantitative feeders used, reduces costs, and can play a role in pre-mixing during the feeding process.

[0030] Please refer to Figures 1 - 7
[0031] S1: Material bins are provided at the tops of the pre-mixing and metering feeding mechanisms 3. The number of the pre-mixing and metering feeding mechanisms 3 is four. Starting from the center of the arc feeding area 2 as the starting direction, and from the starting direction to the end direction, the material bins of the pre-mixing and metering feeding mechanisms 3 store fused white corundum fine powder, fused magnesia, activated alumina powder, and titanium dioxide powder respectively. First, the fused white corundum fine powder, fused magnesia, activated alumina powder, and titanium dioxide powder are quantitatively injected into the cavity of the arc feeding area 2 in sequence through the pre-mixing and metering feeding mechanisms 3, and are coated through the edge of the arc feeding area 2, so that the fused white corundum fine powder, fused magnesia, activated alumina powder, and titanium dioxide powder will not overflow from the side. At this stage, if all the materials are put in, the problem that occurs is that the materials are horizontally stacked inside the arc feeding area 2. At this time, when the primary pushing and mixing mechanism 5 is pushing, due to the influence of the horizontal force, the titanium dioxide powder closest to the end will be affected by the horizontal thrust and enter the feeding hole 22 first. Therefore, adjustment is required through S3, so sequential injection is selected;
[0032] S2: The mixing tank 6 rotates to the feeding hole 22 at the end of the arc feeding area 2 and waits to obtain the pre-mixed material. At this time, there is no substance inside the mixing tank 6. Therefore, when the mixing tank 6 rotates to the feeding hole 22 at one end, the feeding hole 22 corresponds to the feeding port of the mixing tank 6;
[0033] S3: The fused white corundum fine powder and fused magnesia are closest to the primary mixing mechanism 5 for pushing materials, and are first put in. At this time, the fused white corundum fine powder and fused magnesia will accumulate inside the arc feeding area 2. At this time, the mass fraction of the fused white corundum fine powder is adjusted to about 20%, and the mass fraction of the fused magnesia is adjusted to about 15%. During the initial mixing process, the fused white corundum powder and fused magnesia account for a relatively high proportion, so they are fed first. The primary mixing mechanism 5 for pushing materials moves towards the side of the pre-mixing and quantitative feeding mechanism 3, pushing the fused white corundum fine powder and fused magnesia towards the end of the arc feeding area 2 while mixing the fused white corundum fine powder and fused magnesia. During the movement, there is a certain safety distance between the fused white corundum fine powder and fused magnesia and the feeding hole 22, so they will not directly fall through the feeding hole 22 in the unmixed state. When the primary mixing mechanism 5 for pushing materials approaches the feeding points of activated alumina powder and titanium dioxide powder, the activated alumina powder and titanium dioxide powder are fed through the pre-mixing and quantitative feeding mechanism 3. The mass fraction of the activated alumina powder is adjusted to about 4%, and the mass fraction of the titanium dioxide powder is adjusted to about 1%. At this time, after the activated alumina powder is first put in, the titanium dioxide powder is put in. The pre-mixed material composed of the fused white corundum fine powder, fused magnesia, activated alumina powder, and titanium dioxide powder is pushed to the feeding hole 22 of the arc feeding area 2. At this time, the material is sent into the mixing tank 6 through the feeding hole 22 for mixing. According to the above method, until all the mixing tanks 6 obtain the pre-mixed materials for mixing, during the pushing process, after the materials are processed, the mixing time of the materials entering the inside of the mixing tank 6 is shortened. At this time, the mixing tanks 6 rotate in sequence until materials are put in and mixed inside all the mixing tanks 6;
[0034] S4: The fused white corundum aggregate and the binder are put into the other cavity of the arc feeding area 2 through the secondary mixing and quantitative feeding mechanism 4;
[0035] S5: The mixing tank 6 continues to rotate in the original rotation direction. At this time, the mixing tank 6 that first put in the pre-mixed material first reaches the feeding hole 22 at the other end of the arc feeding area 2. As the mixing tank 6 continues to rotate, at this time, the mixing tank 6 that first put in the material first moves into the other cavity of the arc feeding area 2. At this time, the first mixing tank 6 that put in the material is the first to complete the pre-mixing; at this time, the first mixing tank 6 that put in the material is first located at the feeding hole 22, ready to put in the secondary material;
[0036] S6: At this time, the primary feeding and mixing mechanism 5 rotates in the reverse direction, pushing the fused white corundum aggregate and the binder to move simultaneously to the blanking hole 22 and enter the interior of the mixing tank 6. Then, they are put in according to the mixing time difference of the mixing tank 6, so that when the secondary mixed material is put into the mixing tank 6, the pre-mixed material inside the mixing tank 6 is fully mixed. After all the mixing tanks 6 have been filled with the secondary material, at this time, the mixing tank 6 that initially received the secondary material is located at the initial blanking hole 22, and the material is taken out. Repeat the steps of S1, S3, S4, S5, and S6 to achieve cyclic preparation. When the material is put in at this stage, the secondary material is mixed with the material simultaneously under the push of the primary feeding and mixing mechanism 5 in the manner of S3, and then put into the mixing tank 6 through the blanking hole 22. At this time, the mixing tank 6 continues to rotate. The feeding time difference of the mixing tank 6 ensures that when the secondary material is continuously fed, the mixing time of the primary material remains consistent, thus realizing the feeding cycle;
[0037] A rotating disk 11 and a rotating rod 12 are rotatably connected inside the circular bin body 1. The mixing tanks 6 are annularly distributed on the top of the rotating disk 11. The arc-shaped feeding area 2 is located above the mixing tanks 6. The rotating rod 12 is fixedly connected to the primary feeding and mixing mechanism 5 through a driving connecting rod 51; First, the circular bin body 1 is mainly a shell. The rotating disk 11 is driven to rotate by a motor. The mixing tanks 6 are fixed on the surface of the rotating disk 11. A part of the mixing tank 6 is located outside the rotating disk 11, mainly for subsequent discharging. At this time, the rotating rod 12 provides rotational power for the primary feeding and mixing mechanism 5. When the driving connecting rod 51 rotates with the rotating rod 12, it can drive the primary feeding and mixing mechanism 5 to rotate inside the arc-shaped feeding area 2, so as to push the material and achieve feeding the mixing tank 6;
[0038] The inner wall of the arc delivery area 2 is provided with an arc tooth groove 21, and the primary material pushing mixing mechanism 5 includes a pushing plate 56 fixed at the center for pushing materials, and two mixing toothed discs 52 rotatably connected to the bottom of the primary material pushing mixing mechanism 5, and a stirring rod 55 is eccentrically fixedly connected to the mixing toothed disc 52. A transmission gear 54 is rotatably connected to the bottom of the primary material pushing mixing mechanism 5, and the transmission gear 54 is located on the outside of the primary material pushing mixing mechanism 5 and inside the arc tooth groove 21. The mixing toothed disc 52 and the transmission gear 54 are connected to each other through a transmission belt 53. First, when the primary material pushing mixing mechanism 5 rotates, , the transmission gear 54 will cooperate with the arc-shaped tooth groove 21. The transmission gear 54 is a combined gear. The bottom gear is larger than the top gear. The bottom gear is located inside the arc-shaped tooth groove 21 and meshes with it. The top gear is located at the top and cooperates with the transmission belt 53. At this time, the top gear drives the mixing toothed disk 52 to rotate through the transmission belt 53. At this time, the stirring rod 55 is eccentrically fixed on the mixing toothed disk 52, so that when the mixing toothed disk 52 rotates, the stirring rod 55 rotates, thereby mixing the materials. The push plate 56 is mainly used to push the materials inside the circular arc delivery area 2 and push the materials to the end.
[0039] An eccentric guide port 61 is provided at the top of the mixing tank 6, and a mixing motor 62 is installed inside the mixing tank 6. The mixing motor 62 is located below the eccentric guide port 61, and the top opening diameter of the eccentric guide port 61 is larger than the diameter of the discharge hole 22. Since the top of the mixing tank 6 is an open structure, if the material is delivered from above, if a motor is installed above, it will affect the feeding. Therefore, an eccentric guide port 61 is provided, and the top opening diameter of the eccentric guide port 61 is larger than the diameter of the discharge hole 22. Therefore, when the material falls into the mixing tank 6, it is guided into the mixing tank 6 through the eccentric guide port 61, and then mixed by the motor-driven mixing fan blades, thereby avoiding obstructions caused during the material feeding process.
[0040] Both ends of the arc delivery area 2 are semicircular surfaces, and the inner diameter of the discharge hole 22 is consistent with the inner diameter of the semicircular surface; first, the inner diameter of the discharge hole 22 is consistent with the inner diameter of the semicircular surface, and there will be no corner between the discharge hole 22 and the semicircular surface. At this time, the push plate 56 moves to the center of the discharge hole 22 and stops moving, and at this time all the materials will be pushed to the discharge hole 22, and there will be no residue that cannot fall off.
[0041] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
