Description

Technical Field

[0001] This utility model relates to the field of material flow guidance technology, and more specifically, to a flow guidance device for a buffer bin of a grinding mill. Background Technology

[0002] In the production system of the koji-making workshop, the buffer silo of the grinding mill is a key component for material transfer. Its structural design directly affects the continuity and efficiency of the production process. In the existing technology, the lower part of a single grinding mill buffer silo adopts a double funnel structure, with the two funnels corresponding to two independent production lines respectively. This design aims to meet the efficient diversion of materials when two lines are produced in parallel.

[0003] However, in actual production, due to factors such as production planning and equipment maintenance, it is common to only operate one production line. When only one production line is in operation, a large amount of material will accumulate in the hopper and downstream pipes of the non-operational production line. If this accumulated material is not dealt with in time, it is very easy for it to mold and deteriorate in the humid and warm environment of the koji-making workshop, which not only wastes materials but may also affect product quality. To avoid this situation, the current method is to release the accumulated material from the delayed conveyor at the end of each day's production and then manually transport it to the operational production line for koji pressing. This manual handling method not only consumes a lot of labor costs but is also inefficient and cannot meet the needs of modern automated production. It also increases the labor intensity and safety risks of the workers. Utility Model Content

[0004] This utility model aims to provide a flow guiding device for the buffer bin of a grinding mill to solve the problems in the prior art, such as easy material accumulation that prevents single-line production, large material waste, high manual cleaning costs, low production efficiency, high labor intensity for workers, and high personnel safety risks.

[0005] The embodiments of this utility model are implemented as follows:

[0006] This utility model provides a flow guiding device for a buffer chamber of a grinding mill, which includes a stainless steel housing;

[0007] The stainless steel box has a double feed end at the top and a double discharge end at the bottom. The stainless steel box is equipped with a stainless steel insert plate inside, which can slide to isolate either discharge end of the double discharge end.

[0008] In use, the aforementioned dual feed ends guide the material into the interior of the aforementioned stainless steel box. According to the production line that is currently in use, the staff inserts the aforementioned stainless steel plate into the interior of the aforementioned stainless steel box, so that the aforementioned stainless steel plate covers the unused discharge end of the aforementioned dual discharge ends, thereby facilitating the introduction of the material into the production line that is in use, effectively preventing the accumulation of material at the discharge end of the unused production line.

[0009] The buffer hopper guiding device disclosed in this embodiment, by setting a pluggable stainless steel plate inside the stainless steel housing, allows the stainless steel plate to block either of the two discharge ends, facilitating that material only enters the other discharge end. This also prevents material from accumulating at the unused discharge end. Therefore, this buffer hopper guiding device for a grinding mill has the following advantages: it prevents material accumulation, enables switching to single-line production, reduces the risk of material mold and spoilage, avoids material waste, eliminates the need for manual cleaning, reduces labor costs, improves production efficiency, and reduces worker labor intensity and safety risks.

[0010] Optionally: The top surface of the stainless steel box is provided with a first inlet hole and a second inlet hole, and the outer side of the first inlet hole and the second inlet hole is provided with a first feed port and a second feed port. The first feed port is fixedly connected to the first inlet hole, and the second feed port is fixedly connected to the second inlet hole.

[0011] With this configuration, the first feed port and the second feed port are respectively connected to the first inlet hole and the second inlet hole, so that the feed port at the top of the stainless steel box has two feed holes. On the one hand, it is convenient to adopt a one-in-use and one-out-of-use method, which effectively avoids the occurrence of production stoppage when there is a problem with the feed. On the other hand, it is beneficial to use two feed ports when the feed is mixed, so that different materials can enter the stainless steel box at the same time, which makes it easier to control the mixing ratio of the materials.

[0012] Optionally: The bottom surface of the above-mentioned dual discharge end is provided with a first discharge inverted cone groove and a second discharge inverted cone groove, and the outer sides of the first discharge inverted cone groove and the second discharge inverted cone groove are provided with a first discharge port and a second discharge port, the first discharge port is fixedly connected to the first discharge inverted cone groove, and the second discharge port is fixedly connected to the second discharge inverted cone groove.

[0013] With this configuration, the first discharge port and the second discharge port are two production lines. This allows for the emergency use of the other line to resume production if one production line encounters a problem, thereby effectively reducing the risk of production stoppage. The first discharge inverted cone groove and the second discharge inverted cone groove facilitate the falling and guiding of materials, making it easier for materials to be discharged smoothly through the first discharge port and the second discharge port.

[0014] Optionally, a first insert plate groove and a second insert plate groove are respectively provided on both sides of the stainless steel box. The first insert plate groove and the second insert plate groove are symmetrically distributed on both sides of the stainless steel box. The end of the stainless steel insert plate away from the double discharge end can be slidably adapted into the first insert plate groove or the second insert plate groove.

[0015] With this setup, when only a single production line is in use, a large amount of material will accumulate in the hopper and downstream pipes of the unused production line. To prevent the material from becoming moldy and deteriorating due to not being discharged in time, the first or second insert plate slot corresponding to the opposite production line is selected based on the currently running production line. The stainless steel insert plate is inserted into the first or second insert plate slot and abuts against the connection between the first and second discharge cone slots. The stainless steel insert plate then covers the unused first or second discharge cone slot. In this way, the material coming down from the top of the stainless steel box is directly guided into the first or second discharge cone slot that is currently discharging material under the action of the inclined surface of the stainless steel insert plate, effectively preventing the material from accumulating in the hopper and downstream pipes of the unused production line.

[0016] Optionally, the interior of the stainless steel housing is further provided with a positioning rod for isolating the first discharge inverted cone groove and the second discharge inverted cone groove. The positioning rod is located between the first discharge inverted cone groove and the second discharge inverted cone groove, and both ends of the positioning rod are welded to the inner wall of the stainless steel housing. The sides of the first discharge inverted cone groove and the second discharge inverted cone groove near the positioning rod are fixedly connected to the positioning rod.

[0017] With this configuration, the positioning rod allows the inner end of the stainless steel insert plate to abut against the positioning rod, thereby separating the first discharge inverted cone groove and the second discharge inverted cone groove, providing a positioning function for the insertion of the stainless steel insert plate.

[0018] Optionally: A first guide rod and a second guide rod are provided between the positioning rod and the first insert plate groove, which are parallel to each other and spaced apart. The first guide rod and the second guide rod are respectively fixedly connected to the inner wall of the stainless steel box. One end of the first guide rod and the second guide rod corresponds to the positioning rod, and the other end of the first guide rod and the second guide rod corresponds to the first insert plate groove. The stainless steel insert plate abuts against the positioning rod along the guidance of the first guide rod and the second guide rod.

[0019] This configuration allows the stainless steel insert plate to slide along the first and second guide rods, effectively blocking the first discharge cone groove. This facilitates the flow of material from the top of the stainless steel box into the second discharge cone groove via the stainless steel insert plate, preventing material accumulation, mold growth, and deterioration in the first discharge cone groove. Consequently, it avoids the need for manual handling of accumulated material near the end of each production day.

[0020] Optionally, a third guide rod and a fourth guide rod are provided between the positioning rod and the second insert plate groove, which are parallel to each other and spaced apart. The third guide rod and the fourth guide rod are respectively fixedly connected to the inner wall of the stainless steel box. One end of the third guide rod and the fourth guide rod corresponds to the positioning rod, and the other end of the third guide rod and the fourth guide rod corresponds to the second insert plate groove. The stainless steel insert plate abuts against the positioning rod along the guidance of the third guide rod and the fourth guide rod.

[0021] With this configuration, the stainless steel insert plate can slide along the third and fourth guide rods, which facilitates the blocking of the second discharge cone groove. This allows the material coming down from the top of the stainless steel box to be guided into the first discharge cone groove through the stainless steel insert plate, preventing the material from accumulating, becoming moldy, or deteriorating in the second discharge cone groove. This also avoids the need for manual handling of accumulated material at the end of each day's production.

[0022] Optionally, the width of the first insert plate groove and the second insert plate groove is greater than the width of the stainless steel insert plate.

[0023] This design facilitates the smooth passage of the stainless steel insert through the first or second insert slot, enabling the stainless steel insert to be inserted into the stainless steel housing or pulled out of the stainless steel housing.

[0024] Optionally, the width of the stainless steel insert plate is slightly smaller than the gap between the front and rear inner walls of the stainless steel housing.

[0025] This configuration allows the stainless steel insert plate to slide into the interior of the stainless steel housing and isolate the outlet of one of the production lines, while also preventing material from accumulating in the outlet of an inactive production line.

[0026] Optionally, the bottom surface of the stainless steel insert plate can be slidably attached to the upper inclined surface of the first guide rod and the second guide rod or the third guide rod and the fourth guide rod.

[0027] With this configuration, the first guide rod, the second guide rod, the third guide rod, and the fourth guide rod are not only used for guiding the stainless steel insert plate, but also for supporting the middle part of the stainless steel insert plate, preventing the material on the top of the stainless steel box from bending the stainless steel insert plate.

[0028] In summary, the buffer hopper guiding device for a grinding mill disclosed in this utility model has the advantages of preventing material accumulation at the discharge end of an inactive production line, reducing the likelihood of material mold and deterioration, avoiding material waste, eliminating the need for manual cleaning, reducing labor costs, improving production efficiency, and minimizing labor intensity and safety risks for workers.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] Example

[0035] See Figure 1 This embodiment proposes a flow guiding device for a buffer chamber of a grinding mill, including a stainless steel housing 1;

[0036] The stainless steel box 1 has a double feed end 2 at the top and a double discharge end 3 at the bottom. The stainless steel box 1 is equipped with a stainless steel insert plate 4 inside, which can slide to isolate either discharge end of the double discharge end 3.

[0037] In use, the dual feed ends 2 guide the material into the stainless steel box 1. According to the production line that is currently in use, the staff inserts the stainless steel plate 4 into the stainless steel box 1, so that the stainless steel plate 4 covers the unused discharge end of the dual discharge ends 3, which facilitates the material to be introduced into the production line that is in use, effectively avoiding the accumulation of material at the discharge end of the unused production line.

[0038] The buffer hopper guiding device disclosed in this embodiment has the following advantages: by setting a pluggable stainless steel plate 4 inside the stainless steel housing 1, the stainless steel plate 4 can block either of the two discharge ends 3, so that the material can enter only the other discharge end. At the same time, it also avoids the accumulation of material in the unused discharge end. Thus, the buffer hopper guiding device of the grinding mill has the beneficial effects of preventing material accumulation, enabling switching to single-line production, preventing material from becoming moldy and deteriorating, avoiding material waste, eliminating the need for manual cleaning, reducing labor costs, improving production efficiency, reducing the labor intensity of workers and reducing personnel safety risks.

[0039] See Figure 1 The top surface of the stainless steel box 1 is provided with a first inlet hole 5 and a second inlet hole 6. The outer sides of the first inlet hole 5 and the second inlet hole 6 are provided with a first feed port 7 and a second feed port 8. The first feed port 7 is welded to the first inlet hole 5, and the second feed port 8 is welded to the second inlet hole 6. The first feed port 7 and the second feed port 8 are respectively connected to the first inlet hole 5 and the second inlet hole 6, so that the top of the stainless steel box 1 has two feed ports. On the one hand, it is convenient to adopt a one-in-one backup method, which effectively avoids the occurrence of production stoppage when there is a problem with the feed. On the other hand, it is beneficial to use two feed ports when the feed is mixed, so that different materials can enter the stainless steel box 1 at the same time, which makes it easier to control the mixing ratio of materials.

[0040] The bottom surface of the dual discharge end 3 is provided with a first discharge inverted cone groove 9 and a second discharge inverted cone groove 10. The outer sides of the first discharge inverted cone groove 9 and the second discharge inverted cone groove 10 are provided with a first discharge port 11 and a second discharge port 12. The first discharge port 11 is welded to the first discharge inverted cone groove 9, and the second discharge port 12 is welded to the second discharge inverted cone groove 10. The first discharge port 11 and the second discharge port 12 are two production lines. This makes it convenient to use another line to resume production in case of a problem with one production line, thereby effectively reducing the risk of production stoppage. The first discharge inverted cone groove 9 and the second discharge inverted cone groove 10 are conducive to the falling and guiding of materials, so that materials can be smoothly discharged through the first discharge port 11 and the second discharge port 12.

[0041] The stainless steel box 1 has a first insert plate slot 13 and a second insert plate slot 14 on its two sides, respectively. The first insert plate slot 13 and the second insert plate slot 14 are symmetrically distributed on both sides of the stainless steel box 1. The end of the stainless steel insert plate 4 away from the double discharge end 3 can be slidably fitted into the first insert plate slot 13 or the second insert plate slot 14. When only a single production line is in use, a large amount of material will accumulate in the hopper and downstream pipe of the unused production line. In order to avoid mold and deterioration caused by the material not being discharged in time, the first insert plate slot 14 of the opposite production line is selected according to the currently activated production line. The stainless steel insert plate 4 is inserted into the first insert plate slot 13 or the second insert plate slot 14 and abuts against the connection between the first discharge inverted cone slot 9 and the second discharge inverted cone slot 10. The stainless steel insert plate 4 then covers the unused first discharge inverted cone slot 9 or the second discharge inverted cone slot 10. In this way, the material coming down from the top of the stainless steel box 1 is directly guided into the first discharge inverted cone slot 9 or the second discharge inverted cone slot 10 that is discharging material under the action of the inclined surface of the stainless steel insert plate 4, effectively preventing the material from accumulating in the unused production line hopper and downstream pipes.

[0042] See Figure 1 The stainless steel housing 1 is also equipped with a positioning rod 15 for isolating the first discharge inverted cone groove 9 and the second discharge inverted cone groove 10. The positioning rod 15 is located between the first discharge inverted cone groove 9 and the second discharge inverted cone groove 10. The two ends of the positioning rod 15 are welded to the inner wall of the stainless steel housing 1. The sides of the first discharge inverted cone groove 9 and the second discharge inverted cone groove 10 that are close to the positioning rod 15 are both welded to the positioning rod 15. The positioning rod 15 allows the inner end of the stainless steel insert plate 4 to abut against the positioning rod 15, thereby separating the first discharge inverted cone groove 9 and the second discharge inverted cone groove 10 and providing a positioning function for the insertion of the stainless steel insert plate 4.

[0043] A first guide rod 16 and a second guide rod 17 are provided between the positioning rod 15 and the first insert plate groove 13, which are parallel to each other and spaced apart. The first guide rod 16 and the second guide rod 17 are respectively welded to the inner wall of the stainless steel box 1. One end of the first guide rod 16 and the second guide rod 17 corresponds to the positioning rod 15, and the other end of the first guide rod 16 and the second guide rod 17 corresponds to the first insert plate groove 13. The stainless steel insert plate 4 abuts against the positioning rod 15 along the guide of the first guide rod 16 and the second guide rod 17, so that the stainless steel insert plate 4 can slide along the first guide rod 16 and the second guide rod 17, which makes it easier to block the first discharge inverted cone groove 9. This facilitates the material coming down from the top of the stainless steel box 1 to be introduced into the second discharge inverted cone groove 10 through the stainless steel insert plate 4. The first discharge inverted cone groove 9 will not have the problem of material accumulation, mold and deterioration, thus avoiding the need for manual handling of the accumulated material at the end of each day's production.

[0044] A third guide rod 18 and a fourth guide rod 19 are provided between the positioning rod 15 and the second insert plate groove 14, which are parallel to each other and spaced apart. The third guide rod 18 and the fourth guide rod 19 are respectively welded to the inner wall of the stainless steel box 1. One end of the third guide rod 18 and the fourth guide rod 19 corresponds to the positioning rod 15, and the other end of the third guide rod 18 and the fourth guide rod 19 corresponds to the second insert plate groove 14. The stainless steel insert plate 4 abuts against the positioning rod 15 along the guide of the third guide rod 18 and the fourth guide rod 19. The stainless steel insert plate 4 can slide along the third guide rod 18 and the fourth guide rod 19, which makes it easy to block the second discharge inverted cone groove 10. This facilitates the material coming down from the top of the stainless steel box 1 to be introduced into the first discharge inverted cone groove 9 through the stainless steel insert plate 4. The second discharge inverted cone groove 10 will not have the problem of material accumulation, mold and deterioration, thus avoiding the need for manual handling of the accumulated material at the end of each day's production.

[0045] See Figure 1 The width of the first insertion slot 13 and the second insertion slot 14 is greater than the width of the stainless steel insertion plate 4. This makes it easier for the stainless steel insertion plate 4 to pass smoothly through the first insertion slot 13 or the second insertion slot 14, which is beneficial for the stainless steel insertion plate 4 to be inserted into the stainless steel box 1 or to be pulled out of the stainless steel box 1.

[0046] The width of the stainless steel insert plate 4 is slightly smaller than the gap between the front and rear inner walls of the stainless steel box 1. This allows the stainless steel insert plate 4 to slide into the interior of the stainless steel box 1 and isolate the discharge port of one of the production lines, while also preventing material from accumulating in the discharge port of the inactive production line.

[0047] The bottom surface of the stainless steel insert plate 4 can slide against the upper inclined surface of the first guide rod 16 and the second guide rod 17 or the third guide rod 18 and the fourth guide rod 19. The first guide rod 16, the second guide rod 17, the third guide rod 18 and the fourth guide rod 19 are not only used for guiding the stainless steel insert plate 4, but also can support the middle part of the stainless steel insert plate 4, so as to prevent the material on the top of the stainless steel box 1 from bending the stainless steel insert plate 4.

[0048] See Figure 1In this embodiment, the device has a first feed inlet 7 and a second feed inlet 8 welded to the top surface of the stainless steel housing 1, a first discharge outlet 11 and a second discharge outlet 12 welded to the bottom surface of the stainless steel housing 1, a first insert plate groove 13 and a second insert plate groove 14 respectively opened on the two sides of the stainless steel housing 1, a positioning rod 15 welded between the first discharge inverted cone groove 9 and the second discharge inverted cone groove 10 inside the stainless steel housing 1, and a first guide rod 16, a second guide rod 17, a third guide rod 18 and a fourth guide rod 19 welded to the inner wall of the stainless steel housing 1. When production is carried out on a single line, the stainless steel insert plate 4 is simply inserted into the side that is not in production. The stainless steel insert plate 4 enters the stainless steel box 1 through the first insert plate slot 13 or the second insert plate slot 14, and is inserted into the position of the positioning rod 15 according to the predetermined trajectory through the first guide rod 16 and the second guide rod 17 or the third guide rod 18 and the fourth guide rod 19. The material enters from the first feed port 7 and the second feed port 8. Because of the stainless steel insert plate 4, the material on the side that is not in production will slide from the stainless steel insert plate 4 to the other side, so as to achieve the effect of single-line production.

[0049] See Figure 1 The specific steps for using the flow guiding device of the mill buffer chamber in this embodiment are as follows:

[0050] When only the production line at the first discharge port 11 is in use, the operator aligns one end of the stainless steel insert plate 4 with the second insert plate slot 14, inserts the stainless steel insert plate 4 into the second insert plate slot 14, and pushes it against the positioning rod 15 inside the stainless steel box 1 along the third guide rod 18 and the fourth guide rod 19. In this way, the stainless steel insert plate 4 seals the top of the second discharge inverted cone groove 10, preventing materials from falling into the second discharge inverted cone groove 10 and preventing materials from accumulating inside the stainless steel box 1, thus avoiding material mold, deterioration and waste. At the same time, the stainless steel insert plate 4 inserted above the second discharge inverted cone groove 10 has the function of inclined backflow. The materials entering the stainless steel box 1 from the first inlet and the second inlet will slide into the first discharge inverted cone groove 9 along the inclined surface of the stainless steel insert plate 4. This allows the production line corresponding to the first discharge port 11 to start production while the second discharge port 12 does not accumulate materials, avoiding the need for manual cleaning at the end of each day's production.

[0051] When only the production line located at the second discharge port 12 is in use, the operator only needs to pull the stainless steel insert plate 4 out of the second insert plate slot 14, insert the stainless steel insert plate 4 into the first insert plate slot 13, and press it against the positioning rod 15 inside the stainless steel box 1 along the first guide rod 16 and the second guide rod 17. In this way, the stainless steel insert plate 4 seals the area above the first discharge inverted cone groove 9, preventing materials from falling into the first discharge inverted cone groove 9, so as to achieve the effect of single-line production.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
