Description

Technical Field

[0001] The present application relates to the technical field of cement raw meal homogenization, and in particular to a cement raw meal homogenization silo. Background Art

[0002] The material that is ground to a certain fineness by mixing lime raw materials, clay raw materials and a small amount of correction raw materials (sometimes mineralizers, crystal seeds, etc. are also added, and coal is also added during vertical kiln production) in proportion is called cement raw material. Homogenization silo is a large-scale bulk material storage silo that can effectively store granular loose materials, clinker and crushed limestone, as well as powdered loose materials. Homogenization silo is widely used in the cement industry.

[0003] At present, there are three main structures of cement raw meal homogenization devices, namely, multi-store combination, mechanical dump storehouse and compressed air mixing storehouse. Most of them adopt compressed air mixing storehouse to homogenize cement raw meal. It is found in the process of use that the design of the storehouse bottom structure is unreasonable. During the homogenization process, the air intake speed and airflow direction are unstable, which can easily affect the homogenization effect and easily cause the air intake hole to be blocked. In addition, the feed distribution is unreasonable. The cement raw meal is easy to accumulate in the storehouse and it is difficult to turn it over in all directions under the action of airflow, which seriously affects the efficiency of homogenization. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a cement raw meal homogenization tank, which can solve the technical problem of uniform cement raw meal homogenization.

[0005] The embodiment of the present application provides a cement raw meal homogenization silo, comprising a homogenization cylinder, a feed pipe is connected to the homogenization cylinder, a homogenization mechanism is arranged in the middle of the homogenization cylinder, and a discharge port is arranged at the bottom of the homogenization cylinder;

[0006] The homogenizing mechanism comprises a bulk material plate and a blowing assembly. The bulk material plate is fixedly arranged on the inner wall of the homogenizing cylinder. A plurality of vent holes are provided on the bulk material plate. The blowing assembly is located at the lower end of the bulk material plate.

[0007] Furthermore, the bulk plate is arranged in a conical shape.

[0008] Furthermore, a plurality of partitions are arranged in a circular array on the bulk plate.

[0009] Furthermore, the blowing assembly includes an air storage cavity and a plurality of blowers, the air storage cavity is fixedly arranged at the lower end of the bulk plate, the plurality of blowers are fixedly arranged on the outer wall of the homogenizing cylinder, and the blowers are connected to the interior of the air storage cavity.

[0010] Furthermore, a discharge valve is provided at the bottom of the gas storage cavity.

[0011] Furthermore, the feed pipe is a three-way pipe, and a spiral feed assembly is arranged in the middle part of the feed pipe. The spiral feed assembly includes a motor and a spiral stirring shaft. The motor is fixedly arranged on the feed pipe, and the spiral stirring shaft is rotatably mounted on the feed pipe, and the output end of the motor is fixedly connected to the spiral stirring shaft.

[0012] Furthermore, the bottom of the homogenizing cylinder is arranged to be inclined toward the discharge port.

[0013] Beneficial effects of the utility model:

[0014] The homogenizing mechanism provided by the utility model can blow air from bottom to top on the bulk material plate through the air blowing component, so that the raw materials dropped on the bulk material plate can be blown upwards and then dropped again, and the repetition of this process can make the raw materials on the bulk material plate be better blown and homogenized, thereby improving the homogenization efficiency of the raw materials in the homogenizing bin.

[0028] The embodiment of the present application discloses a cement raw meal homogenization silo.

[0029] Reference Figure 1-4 A cement raw meal homogenizing silo comprises a homogenizing cylinder 1, a feed pipe 11 is connected to the homogenizing cylinder 1, a homogenizing mechanism 2 is arranged in the middle of the homogenizing cylinder 1, and a discharge port 12 is arranged at the bottom of the homogenizing cylinder 1;

[0030] The homogenizing mechanism 2 includes a bulk material plate 21 and a blowing assembly 22. The bulk material plate 21 is fixedly arranged on the inner wall of the homogenizing cylinder 1. A plurality of vent holes 211 are provided on the bulk material plate 21. The blowing assembly 22 is located at the lower end of the bulk material plate 21.

[0031] During use, when the raw material falls from the feed pipe 11 and falls onto the bulk plate 21 of the homogenizing mechanism 2, the blowing component 22 blows air from the bottom of the bulk plate 21, so that the wind blows upward through the vent hole 211, and the raw material that has fallen onto the bulk plate 21 can be blown upward and then fall again. This repetition can make the raw material on the bulk plate 21 better blown and homogenized, thereby improving the homogenization efficiency of the raw material in the homogenizing bin.

[0032] Reference Figure 2-3 The bulk material plate 21 is arranged in a conical shape, which can facilitate the discharge of the raw materials after mixing and prevent the raw materials from piling up on the bulk material plate 21.

[0033] Reference Figure 2-4 A plurality of partitions 212 are arranged in a circular array on the bulk plate 21, which can effectively separate and homogenize the falling raw materials, and prevent too much raw materials from falling in one place, resulting in the inability of the blowing component to blow up the raw materials.

[0034] Reference Figure 2-4 The blowing assembly 22 includes an air storage cavity 221 and a plurality of blowers 222. The air storage cavity 221 is fixedly arranged at the lower end of the bulk plate 21. The plurality of blowers 222 are fixedly arranged on the outer wall of the homogenizing cylinder 1, and the blowers 222 are connected with the inside of the air storage cavity 221. When in use, the blowers 222 blow air into the air storage cavity 221, and the air is continuously blown upward from the air vents 211, so that the raw material can be effectively blown away, thereby improving the homogenization effect of the raw material.

[0035] Reference Figure 2-3 A discharge valve 223 is provided at the bottom of the gas storage cavity 221 to facilitate the downward discharge of the raw material that falls into the gas storage cavity 221.

[0036] Reference Figure 2The feed pipe 11 is a three-way pipe, and a spiral feed assembly 3 is arranged in the middle of the feed pipe 11. The spiral feed assembly 3 includes a motor 31 and a spiral stirring shaft 32. The motor 31 is fixedly arranged on the feed pipe 11, and the spiral stirring shaft 32 is rotatably installed on the feed pipe 11, and the output end of the motor 31 is fixedly connected to the spiral stirring shaft 32. When in use, the motor 31 drives the spiral stirring shaft 32 to rotate, which can effectively control the feeding speed of the feed pipe 11 and avoid blockage at the feed pipe 11.

[0037] Reference Figure 3 The bottom of the homogenizing drum 1 is tilted toward the discharge port 12 to facilitate the discharge of the raw material after homogenization and prevent the raw material from accumulating at the bottom and affecting the homogenization effect.

[0038] 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.
