Description

Technical Field

[0001] The present application relates to the technical field of cement production equipment, and in particular to a feed bin for cement raw materials. Background Art

[0002] Cement is a powdery hydraulic inorganic gelling material, which becomes a slurry after adding water and mixing. It can harden in the air or in water, and can firmly bond sand, stone and other materials together. The early mixture of lime and volcanic ash is very similar to the modern lime pozzolana cement. It is used to bond concrete made of crushed stone. After hardening, the concrete not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, it has been widely used in civil construction, water conservancy, national defense and other projects as an important cementing material.

[0003] At present, the main raw materials for producing cement are limestone and clay, which are ground and mixed evenly in a certain proportion to form raw materials, and then fed into the cement kiln to be calcined into clinker. However, when the raw materials are fed, the smoke in the kiln will flow back into the feed bin, causing dust to easily occur at the feed port of the feed bin. A large amount of dust will be generated and pour out from the feed port, affecting the surrounding environment and the health of the workers. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a feed bin for cement raw materials, which can solve the technical problem of preventing the backflow of smoke in the kiln when the feed bin is feeding materials into the cement kiln.

[0005] An embodiment of the present application provides a feed bin for cement raw materials, including a feed bin, wherein the feed bin includes a storage portion and a discharge portion, the discharge portion is arranged in a constricted shape, a partition component is arranged at the discharge end of the storage portion, and a dividing component is arranged at the feed end of the discharge portion.

[0006] Furthermore, the partition assembly includes a first rotating plate, a second rotating plate, a first gear, a second gear and a driving motor, the first rotating plate and the second rotating plate are rotatably arranged on the material storage part, and both ends of the first rotating plate and both ends of the second rotating plate pass through the side wall of the feed bin, one end of the first rotating plate is connected to the first gear, the other end of the first rotating plate is connected to the driving motor, one end of the second rotating plate is connected to the second gear, and the first gear is meshed with the second gear.

[0007] Furthermore, the material dividing assembly includes a plurality of partition plates, and the partition plates are located at the necked end of the discharge portion.

[0008] Furthermore, a vibration motor is fixedly provided on the outer wall of the discharge portion, and the vibration motor is located beside the material discharging assembly.

[0009] Furthermore, a plurality of blowers are fixedly provided at the upper end of the discharge portion, and the air outlet ends of the blowers are connected to the interior of the discharge portion.

[0010] Furthermore, the air outlet end of the blower is also provided with a wind shield, and the wind shield is fixedly arranged on the inner wall of the discharge part.

[0011] Beneficial effects of the utility model:

[0012] The partition component provided by the utility model can effectively control the discharge amount and discharge flow rate of the raw material from the storage part. At the same time, after a certain amount of raw material is discharged, the partition component is controlled to completely separate the storage part and the discharge part. When the raw material is discharged into the kiln by the discharge part, the smoke in the kiln can be prevented from flowing back into the feed bin, which would cause dust to easily occur at the feed port of the feed bin, thereby ensuring the working environment when feeding into the kiln.

[0013] By setting up the blower, the wind pressure in the discharge section can be effectively guaranteed to prevent the air pressure in the kiln from being too high, which will cause the raw materials in the discharge section to be unable to be completely discharged and cause blockage.

[0027] The embodiment of the present application discloses a feed bin for cement raw materials.

[0028] Reference Figure 1-4 A feed bin for cement raw materials comprises a feed bin 1, wherein the feed bin 1 comprises a storage portion 11 and a discharge portion 12, wherein the discharge portion 12 is arranged in a constricted shape, a partition component 2 is arranged at the discharge end of the storage portion 11, and a dividing component 3 is arranged at the feed end of the discharge portion 12; when in use, the raw material is stored on the feed bin 1, and the raw material is discharged from the storage portion 11 to the discharge portion 12 by controlling the partition component 2, and the raw material is effectively diverted by the dividing component 3 and discharged from the discharge portion 12; The material section 12 is discharged into the kiln. Through the setting of the partition component 2, the discharge amount and discharge flow rate of the raw material from the storage section 11 can be effectively controlled. At the same time, after a certain amount of raw material is discharged, the partition component 2 is controlled to completely separate the storage section 11 and the discharge section 12. When the raw material is discharged into the kiln from the discharge section 12, the smoke in the kiln can be prevented from flowing back into the feed bin 1, which would cause dust to easily occur at the feed port of the feed bin 1, thereby ensuring the working environment when feeding into the kiln.

[0029] Reference Figure 1-4 The partition assembly 2 includes a first rotating plate 21, a second rotating plate 22, a first gear 23, a second gear 24 and a driving motor 25. The first rotating plate 21 and the second rotating plate 22 are rotatably arranged on the material storage portion 11, and both ends of the first rotating plate 21 and the second rotating plate 22 pass through the side wall of the feed bin 1. One end of the first rotating plate 21 is connected to the first gear 23, and the other end of the first rotating plate 21 is connected to the driving motor 25. One end of the second rotating plate 22 is connected to the second gear 24. The first gear 23 is meshed with the second gear 24. In this embodiment, the driving motor 25 adopts a motor with a gear reduction box;

[0030] When in use, the driving motor 25 drives the first rotating plate 21 to rotate, and the rotation of the first rotating plate 21 drives the first gear 23 to rotate. The first gear 23 meshes with the second gear 24 to drive the second gear 24 to rotate and simultaneously drives the second rotating plate 22 to rotate, which can effectively make the first rotating plate 21 and the second rotating plate 22 flip in a mirror image, and effectively control the discharge amount and flow rate of the raw material. At the same time, when the raw material is discharged to a certain amount, the driving motor 25 drives the first rotating plate 21 and the second rotating plate 22 to be flush with each other, and the first rotating plate 21 and the second rotating plate 22 can seal and block the material storage part 11, so that the material storage part 11 and the discharge part 12 are completely separated, and when the raw material is discharged into the kiln from the discharge part 12, the smoke in the kiln is prevented from flowing back into the feed bin 1, which makes it easy for dust to occur at the feed port of the feed bin 1, thereby ensuring the working environment when feeding into the kiln.

[0031] Reference Figure 2-3 The material dividing assembly 3 includes a plurality of partition plates 31, and the partition plates 31 are located at the end of the constriction of the discharge portion 12. The arrangement of the partition plates 31 can effectively separate and divert the raw material, thereby preventing the raw material from falling into the constriction of the discharge portion 12 and causing accumulation and blockage.

[0032] Reference Figure 1-2 A vibration motor 4 is fixedly installed on the outer wall of the discharge part 12, and the vibration motor 4 is located next to the material dividing component 3. The setting of the vibration motor 4 can effectively vibrate the inner wall of the discharge part 12 to loosen the raw material and prevent the raw material from adhering to the inner wall. At the same time, the partition plate 31 is vibrated to better make the inside of the discharge part 12 locally vibrate and reduce blockage.

[0033] Reference Figure 1-3 A plurality of blowers 5 are fixedly arranged at the upper end of the discharge portion 12, and the blowers 5 are fixedly arranged on the side wall of the discharge portion 12 at an angle, and the air outlet end of the blower 5 is connected with the inside of the discharge portion 12. Through the arrangement of the blowers 5, the wind pressure in the discharge portion 12 can be effectively guaranteed to prevent the air pressure in the kiln from being too high, which may cause the raw material in the discharge portion 12 to be unable to be completely discharged and cause blockage.

[0034] Reference Figure 2-3 The air outlet end of the blower 5 is also provided with a wind shield 51, which is fixedly arranged on the inner wall of the discharge portion 12. The setting of the wind shield 51 can effectively prevent the raw material from being discharged to the outlet of the blower 5 during the falling process.

[0035] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
