Description

Technical Field

[0001] This invention relates to the technical field of bulk material structures, and in particular to a vertical cement raw material mill spraying and spreading device. Background Technology

[0002] Vertical cement raw meal mills, as core equipment in modern cement production processes, are widely used to grind and mix various raw materials (such as limestone, clay, iron powder, etc.) into homogeneous raw meal powder. Compared with traditional ball mills, vertical mills have higher grinding efficiency, lower energy consumption, and stronger drying capacity, and therefore have been rapidly promoted and applied in the cement industry.

[0003] In the operation of a vertical cement raw meal mill, the uniform distribution and proper feeding of materials are key factors in ensuring grinding quality and efficiency. Therefore, a spray dispersing structure is required in raw meal mills to facilitate the uniform diffusion of raw materials into the grinding bed. The existing spray dispersing structure mainly consists of a rotating disc and a guide plate set at the edge of the disc. During material distribution, the raw material falls onto the rotating disc, which centrifugally diffuses the raw material in all directions and then disperses it downwards into the raw meal mill through the guide plate, thus achieving material dispersion. However, in practical applications, this also exposes some technical problems, such as the raw material only being able to disperse from the edge of the disc. From a top-down perspective, the dispersion trajectory of the raw material is circular, meaning the raw material falls in a linear fashion rather than a planar fashion, resulting in the raw material being relatively concentrated and having poor dispersion. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a vertical cement raw meal mill spraying and spreading device, the specific technical solution of which is as follows:

[0005] A vertical cement raw material mill spraying device includes a feeding pipe, a first disc, and a second disc. The first disc and the second disc are arranged vertically and coaxially. The space between the first disc and the second disc is designated as a material equalization space. The feeding pipe is vertically installed on the top of the first disc and is used to feed material into the material equalization space. A retaining ring is provided at the edge of the second disc, and the first disc contacts the retaining ring. Multiple long troughs for dispersing material are provided at the bottom of the second disc. The length direction of the long troughs is along the radial direction of the second disc. The long troughs are connected to the material equalization space. A long outlet for discharging material is provided at the bottom of the long troughs. The length direction of the outlet is along the radial direction of the second disc. A first rotating shaft is rotatably provided inside the long troughs. Multiple partitions are provided on the outer wall of the first rotating shaft. The space between two adjacent partitions is used to store raw materials. When two adjacent partitions are in contact with the inner wall of the long troughs, the space formed between the two adjacent partitions is sealed.

[0006] The second disk rotates and is used to diffuse the raw materials in the uniform material space outward. The middle part of the uniform material space is set as a cone, and the edge of the uniform material space is set as a horizontal ring. Multiple bulk material long trough plates are located in the ring area of ​​the uniform material space.

[0007] Furthermore, the first rotating shaft is hollow inside, and an exhaust port is provided on the outer wall of the first rotating shaft between two adjacent partitions. An arc-shaped baffle is provided inside the first rotating shaft, and both ends of the arc-shaped baffle are fixed to the side wall of the bulk material trough plate, with the opening of the arc-shaped baffle facing downward.

[0008] When the exhaust port rotates to the opening position of the arc-shaped baffle, the exhaust port is connected to the inside of the first rotating shaft. When the exhaust port deviates from the opening position of the arc-shaped baffle, the arc-shaped baffle blocks the exhaust port, and the high-pressure gas in the first rotating shaft is ejected downward through the opening of the arc-shaped baffle, that is, the exhaust port at the bottom of the first rotating shaft.

[0009] Furthermore, a rotating tube is rotatably provided on the end face of the bulk material trough plate facing the axis of the second disc. An opening is provided on the end face of the bulk material trough plate inside the rotating tube. The rotating tube is connected to the first rotating shaft through the opening. An auxiliary shaft is rotatably installed inside the opening. Both ends of the auxiliary shaft are provided with first transmission wheels. One of the first transmission wheels is connected to the inner wall of the rotating tube, and the other first transmission wheel is located at the opening of the arc-shaped baffle and is connected to the inner wall of the first rotating shaft. High-pressure gas is supplied into the first rotating shaft through the rotating tube and the opening.

[0010] Furthermore, a support plate is provided inside the feeding pipe. The support plate has a triangular cross-sectional shape and its opening faces downward. A second rotating shaft is fixed inside the support plate. A power sleeve is rotatably sleeved on the outer wall of the second rotating shaft. The power sleeve is connected to the second disc. The bottom of the second rotating shaft passes through the second disc. The second rotating shaft and the second disc rotate relative to each other. A transmission disc is provided on the second rotating shaft. A second transmission wheel is provided on each rotating pipe. The second transmission wheel is connected to the transmission disc in a transmission connection.

[0011] The support plate contains a first motor and a third transmission wheel for providing rotational power to the power sleeve.

[0012] Furthermore, the second rotating shaft is hollow, and the feed pipe is provided with an air inlet hose that communicates with the second rotating shaft and is used to supply high-pressure gas into the second rotating shaft. A gas guide chamber is rotatably sleeved at the bottom of the second rotating shaft. Multiple gas guide holes are opened on the outer wall of the second rotating shaft inside the gas guide chamber. The second rotating shaft communicates with the gas guide chamber through the gas guide holes. Multiple gas guide pipes are provided on the gas guide chamber. The gas guide pipes communicate with the rotating pipe, and the rotating pipe and the gas guide pipes rotate relative to each other.

[0013] Furthermore, the retaining ring slides relative to the first disc in the vertical direction, and the feeding pipe is provided with an adjustment structure, which is used to adjust the height position of the retaining ring and the second disc;

[0014] The support plate slides vertically on the inner wall of the feed pipe.

[0015] Furthermore, the adjustment structure includes a thread on the outer wall of the feed pipe and a threaded ring screwed onto the thread. A first connecting ring is rotatably sleeved on the threaded ring, and a second connecting ring is rotatably sleeved on the inner wall of the retaining ring. The first connecting ring and the second connecting ring are connected by a plurality of first inclined arms.

[0016] The feeding pipe is equipped with a second motor, and the output end of the second motor is equipped with a toothed column. The outer wall of the threaded ring is provided with teeth, and the toothed column meshes with the teeth on the threaded ring.

[0017] Furthermore, each of the first inclined arms is slidably fitted with a sliding sleeve, and the sliding sleeve is connected to the first disk through a second inclined arm.

[0018] The advantages of this invention are:

[0019] By designing a second rotating disc to diffuse the raw material outwards, combined with the annular distribution of multiple bulk material troughs, the raw material not only falls evenly along the circumference but also achieves a wider radial distribution. This "planar" falling method greatly improves the uniformity of raw material distribution in the raw meal mill, which is beneficial to improving grinding quality and efficiency. The conical design in the center of the material distribution space helps the raw material flow smoothly to all sides, avoiding accumulation in the central area and improving the flowability of the raw material. In addition, through the cooperation of the first rotating shaft and the partition, the raw material can be precisely controlled and evenly distributed into each bulk material trough, further improving the efficiency and accuracy of raw material processing. The presence of the first disc not only limits the flow range of the raw material but also limits the thickness of the raw material, ensuring that the raw material layer thickness on the second disc is uniform. This is crucial for maintaining the uniform distribution of raw material in the mill. In summary, this spraying device, through its innovative structural design, effectively solves the problems of uneven raw material distribution and low processing efficiency in traditional spraying structures, providing strong support for the efficient and stable operation of cement raw meal mills.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0034] like Figures 1 to 7 As shown, the vertical cement raw material mill spraying device of the present invention includes a feeding pipe 1, a first disc 2 and a second disc 3. The first disc 2 and the second disc 3 are arranged vertically and coaxially. The space between the first disc 2 and the second disc 3 is designated as a material equalization space. The feeding pipe 1 is vertically installed on the top of the first disc 2 and is used to feed material into the material equalization space. A retaining ring 4 is provided at the edge of the second disc 3, and the first disc 2 contacts the retaining ring 4. Multiple dispersion points are provided at the bottom of the second disc 3. The long material trough 5 has its length direction along the radial direction of the second disk 3. The long material trough 5 is connected to the material equalization space. The bottom of the long material trough 5 is provided with a long opening for discharging material. The length direction of the long opening is along the radial direction of the second disk 3. The long material trough 5 is rotatably provided with a first rotating shaft 6. The outer wall of the first rotating shaft 6 is provided with multiple partitions 7. The space between two adjacent partitions 7 is used to store raw materials. When two adjacent partitions 7 are in contact with the inner wall of the long material trough 5, the space formed between the two adjacent partitions 7 is sealed.

[0035] The second disk 3 rotates and is used to spread the raw materials in the uniform material space outward. The middle part of the uniform material space is set as a cone, and the edge of the uniform material space is set as a horizontal ring. Multiple bulk material long trough plates 5 are all located in the ring area of ​​the uniform material space.

[0036] In detail, the first disc 2, the second disc 3, and the baffle ring 4 form a closed space. The material equalization space between the first disc 2 and the second disc 3 is flat, which facilitates the limitation of the raw material flow rate. The feed pipe 1 is used to supply raw materials into the material equalization space between the first disc 2 and the second disc 3. Since the middle part of the material equalization space is conical, it is convenient to transport the raw material from the middle of the material equalization space to the area where multiple bulk material long trough plates 5 are located. At the same time, since the second disc 3 can rotate, it can avoid the poor centrifugal effect of the second disc 3 on the raw material when the raw material is in the middle of the material equalization space, which would cause the raw material to be blocked in the middle of the material equalization space. It is convenient to allow the raw material to spread quickly to the surrounding areas. When the raw material moves to the position of the bulk material long trough plate 5, the raw material falls into the space between two adjacent partitions 7 inside the bulk material long trough plate 5, and the raw material fills the space between the two adjacent partitions 7. As the first rotating shaft 6 rotates, the first rotating shaft 6 carries the two adjacent partitions 7 and the raw material between them downwards. When the raw material moves to the position of the long opening at the bottom of the bulk material long trough plate 5, the raw material falls downwards through the long opening. At this time, the raw material falls in a linear shape. Since the length direction of the long opening is along the radial direction of the second disk 3, and the second disk 3 rotates, the raw material falling in a linear shape follows the second disk 3 in a synchronous circumferential motion, so that the raw material falls in a planar shape, realizing the uniform distribution of raw materials.

[0037] It should be noted that, since the second disk 3 rotates and causes the raw material on it to be centrifugally dispersed in all directions, in order to prevent the raw material from jumping and falling off the second disk 3 at will, and to avoid inconsistent thickness of the raw material on the second disk 3, the first disk 2 is used to restrict the raw material. It can both prevent the raw material from jumping and dispersing at will, and limit the thickness of the raw material on the second disk 3, so as to make the thickness of the raw material between the first disk 2 and the second disk 3 consistent and improve the uniformity of the material distribution.

[0038] In actual use, since the raw material is centrifugally pushed by the second disc 3 and enters between two adjacent partitions 7, and the two partitions 7 will rotate with the first rotating shaft 6, even if the raw material between the two adjacent partitions 7 is not full, the raw material can still be evenly distributed between the two adjacent partitions 7 during the raw material transportation process, thereby ensuring that the pigment discharged from the long opening is uniform. In addition, the setting of the first rotating shaft 6 and multiple partitions 7 can prevent the raw material in the uniform material space from directly entering the bulk material long trough plate 5 and being discharged through the long opening, avoiding the accumulation of raw material discharged from the long opening and the inability to achieve uniform material discharge.

[0039] By designing a rotating second disc 3 to diffuse the raw material outwards, combined with the annular distribution of multiple long material troughs 5, the raw material not only falls evenly along the circumference but also achieves a wider radial distribution. This "planar" falling method greatly improves the uniformity of raw material distribution in the raw meal mill, which is beneficial to improving grinding quality and efficiency. The conical design in the middle of the material distribution space helps the raw material flow smoothly to all sides, avoiding accumulation in the central area and improving the flowability of the raw material. In addition, through the cooperation of the first rotating shaft 6 and the partition 7, the raw material can be precisely controlled and evenly distributed into each long material trough 5, further improving the efficiency and accuracy of raw material processing. The presence of the first disc 2 not only limits the flow range of the raw material but also limits the thickness of the raw material, ensuring that the thickness of the raw material layer on the second disc 3 is uniform. This is crucial for maintaining the uniform distribution of raw material in the mill. In summary, this spraying device, through its innovative structural design, effectively solves the problems of uneven raw material distribution and low processing efficiency in traditional spraying structures, providing strong support for the efficient and stable operation of cement raw meal mills.

[0040] like Figure 7 As shown, the first rotating shaft 6 is hollow inside, and an exhaust port 8 is provided on the outer wall of the first rotating shaft 6 between two adjacent partitions 7. An arc-shaped baffle 9 is provided inside the first rotating shaft 6. Both ends of the arc-shaped baffle 9 are fixed on the side wall of the bulk material long trough plate 5, and the opening of the arc-shaped baffle 9 faces downward.

[0041] When the exhaust port 8 rotates to the opening position of the arc-shaped baffle 9, the exhaust port 8 is connected to the inside of the first rotating shaft 6. When the exhaust port 8 deviates from the opening position of the arc-shaped baffle 9, the arc-shaped baffle 9 blocks the exhaust port 8, and the high-pressure gas in the first rotating shaft 6 is ejected downward through the exhaust port 8 at the bottom of the first rotating shaft 6 through the opening of the arc-shaped baffle 9.

[0042] In detail, the first rotating shaft 6 is tubular in shape, with both ends rotatably mounted on the inner wall of the bulk material trough 5. The arc-shaped baffle 9 is located inside the first rotating shaft 6, and both ends of the arc-shaped baffle 9 are fixed to the inner wall of the bulk material trough 5. The first rotating shaft 6 stores high-pressure gas. When the first rotating shaft 6 rotates and transports raw materials, the exhaust port 8 moves with the raw materials to the bottom of the first rotating shaft 6. At this time, the exhaust port 8 is located at the opening position of the arc-shaped baffle 9. The high-pressure gas in the first rotating shaft 6 is sprayed downward through the exhaust port 8. The high-pressure gas can drain the raw materials between the two adjacent baffles 7, thereby avoiding the accumulation of raw materials. At the same time, the discharged high-pressure gas can blow away the raw materials, thereby facilitating the large-area dispersion of the raw materials and improving the material distribution effect. When the exhaust port 8 deviates from the bottom opening of the arc-shaped baffle 9, the arc-shaped baffle 9 blocks the exhaust port 8. At this time, the high-pressure gas in the first rotating shaft 6 cannot be discharged through the exhaust port 8.

[0043] The above-described structural method enables the spraying and dispersing of raw materials.

[0044] like Figure 8 As shown, a rotating tube 10 is rotatably mounted on the end face of the bulk material trough 5 facing the axis of the second disk 3. An opening is provided on the end face of the bulk material trough 5 inside the rotating tube 10. The rotating tube 10 is connected to the first rotating shaft 6 through the opening. An auxiliary shaft 11 is rotatably mounted inside the opening. Both ends of the auxiliary shaft 11 are provided with first transmission wheels 12. One of the first transmission wheels 12 is connected to the inner wall of the rotating tube 10, and the other first transmission wheel 12 is located at the opening of the arc-shaped baffle 9. This first transmission wheel 12 is connected to the inner wall of the first rotating shaft 6. High-pressure gas is supplied into the first rotating shaft 6 through the rotating tube 10 and the opening.

[0045] In detail, the rotating tube 10 is rotatably mounted on the end face of the bulk material trough plate 5. A through-hole is opened on a partial side wall of the bulk material trough plate 5 between the rotating tube 10 and the first rotating shaft 6. The through-hole is used to connect the rotating tube 10 and the first rotating shaft 6. High-pressure gas can be supplied into the first rotating shaft 6 through the rotating tube 10 and the through-hole. At the same time, when the rotating tube 10 rotates, the rotating tube 10 can drive the first rotating shaft 6 to rotate synchronously through the auxiliary shaft 11 and the two first transmission wheels 12, thereby realizing the rotational movement of the first rotating shaft 6 and multiple partitions 7.

[0046] It should be noted that this structural design can fix both ends of the arc-shaped baffle 9, while in the traditional method, the first rotating shaft 6 and the rotating tube 10 are designed with the same structure, which can only fix one end of the arc-shaped baffle 9, and its structural integrity, sealing and firmness are poor.

[0047] like Figures 4 to 8 As shown, the feed pipe 1 is provided with a support plate 13. The cross-sectional shape of the support plate 13 is triangular and its opening faces downward. A second rotating shaft 14 is fixed inside the support plate 13. A power sleeve 15 is rotatably sleeved on the outer wall of the second rotating shaft 14. The power sleeve 15 is connected to the second disc 3. The bottom of the second rotating shaft 14 passes through the second disc 3. The second rotating shaft 14 and the second disc 3 rotate relative to each other. A transmission disc 16 is provided on the second rotating shaft 14. A second transmission wheel 17 is provided on each rotating pipe 10. The second transmission wheel 17 is connected to the transmission disc 16 in a transmission connection.

[0048] The support plate 13 is equipped with a first motor 18 and a third transmission wheel 19 for providing rotational power to the power sleeve 15.

[0049] In detail, the second rotating shaft 14 and the first motor 18 are both fixed inside the support plate 13. The shape of the support plate 13 can be used to divert and block raw materials. The support plate 13 and the second rotating shaft 14 can provide support for the transmission disc 16. The third transmission wheel 19 is installed on the output end of the first motor 18 and is connected to the side wall of the power sleeve 15. The first motor 18 drives the power sleeve 15 to rotate through the third transmission wheel 19. The power sleeve 15 drives the second disc 3 to rotate, thereby providing power to the second disc 3. At the same time, the second disc 3 drives the bulk material long trough plate 5 to move synchronously. The bulk material long trough plate 5 drives the second transmission wheel 17 on it to roll on the transmission disc 16, thereby providing power for the rotation of the rotating tube 10 and the first rotating shaft 6.

[0050] like Figures 4 to 5 As shown, the second rotating shaft 14 is hollow. The feed pipe 1 is provided with an air inlet hose 20 that communicates with the second rotating shaft 14 and is used to supply high-pressure gas into the second rotating shaft 14. The bottom of the second rotating shaft 14 is rotatably fitted with an air guide chamber 21. Multiple air guide holes 22 are opened on the outer wall of the second rotating shaft 14 inside the air guide chamber 21. The second rotating shaft 14 communicates with the air guide chamber 21 through the air guide holes 22. Multiple air guide pipes 23 are provided on the air guide chamber 21. The air guide pipes 23 are communicated with the rotating pipe 10, and the rotating pipe 10 and the air guide pipes 23 rotate relative to each other.

[0051] In detail, high-pressure gas can be supplied into the second rotating shaft 14 through the air inlet hose 20. The high-pressure gas in the second rotating shaft 14 is discharged into the air guide chamber 21 through multiple air guide holes 22 and into each rotating tube 10 through multiple air guide pipes 23, thereby realizing the supply of high-pressure gas.

[0052] When the rotating tube 10 rotates with the second disk 3, the rotating tube 10 will drive the air chamber 21 to rotate on the second rotating shaft 14 through the air guide tube 23. When the rotating tube 10 rotates, the rotating tube 10 will rotate relative to the air guide tube 23. At this time, the rotating tube 10 and the air guide tube 23 remain in communication.

[0053] The retaining ring 4 slides relative to the first disk 2 in the vertical direction. The feeding pipe 1 is provided with an adjustment structure, which is used to adjust the height position of the retaining ring 4 and the second disk 3.

[0054] The support plate 13 slides vertically on the inner wall of the feed pipe 1.

[0055] In detail, the adjustment structure can drive the retaining ring 4 to move up and down, thereby driving the second disc 3 to move up and down. At this time, the size of the material equalization space between the second disc 3 and the first disc 2 changes, thereby adjusting the thickness of the raw material and the raw material supply speed in the material equalization space. When the second disc 3 moves up and down, it can push the support plate 13 to move up and down synchronously in the feeding pipe 1 through the second rotating shaft 14 and the power sleeve 15.

[0056] like Figure 3 As shown, the adjustment structure includes a thread on the outer wall of the feed pipe 1 and a threaded ring 24 screwed onto the thread. A first connecting ring 25 is rotatably sleeved on the threaded ring 24, and a second connecting ring 26 is rotatably sleeved on the inner wall of the retaining ring 4. The first connecting ring 25 and the second connecting ring 26 are connected by a plurality of first inclined arms 27.

[0057] The feed pipe 1 is equipped with a second motor 28, and the output end of the second motor 28 is equipped with a toothed post 29. The outer wall of the threaded ring 24 is provided with teeth, and the toothed post 29 meshes with the teeth on the threaded ring 24.

[0058] In detail, one end of the first inclined arm 27 is rotatably mounted on the first connecting ring 25, and the other end of the first inclined arm 27 is rotatably mounted on the second connecting ring 26. When the second motor 28 drives the toothed column 29 to rotate, the toothed column 29 can drive the threaded ring 24 to rotate. Since the threaded ring 24 is screwed to the feed pipe 1, the threaded ring 24 moves up and down. The threaded ring 24 drives the second connecting ring 26 to move up and down synchronously through the first connecting ring 25 and multiple first inclined arms 27. The second connecting ring 26 drives the retaining ring 4 to move up and down, thereby adjusting the height position of the second disc 3.

[0059] Since the second disc 3 and the retaining ring 4 need to be able to rotate, the retaining ring 4 is rotatably connected to the second connecting ring 26.

[0060] like Figure 3 As shown, each of the first inclined arms 27 is slidably fitted with a sliding sleeve 30, and the sliding sleeve 30 is connected to the first disk 2 through the second inclined arm 31.

[0061] In detail, the second inclined arm 31 is tilted, one end of the second inclined arm 31 is rotatably mounted on the sliding sleeve 30, and the other end of the second inclined arm 31 is rotatably mounted on the first disc 2. When the first inclined arm 27 tilts, the first inclined arm 27 will slide relative to the sliding sleeve 30, and the first inclined arm 27 drives the second inclined arm 31 to tilt through the sliding sleeve 30. Through the sliding sleeve 30 and the second inclined arm 31, the position of the first inclined arm 27 can be limited, thereby preventing the first inclined arm 27 from rotating on the first disc 2.

[0062] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
