Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to an intelligent control cement air conveying chute. Background Technique

[0002] An air conveying chute is used for transporting easily fluidized powdery materials such as cement and fly ash, and is widely used in the conveying of powder materials in industries such as chemical industry, grain, metallurgy, and building materials. The existing air conveying chute is generally formed by connecting an upper box body and a lower box body. A breathable layer is arranged between the upper box body and the lower box body. Air is blown into the lower box body by a dedicated blower and is distributed among the material particles through the breathable layer with dense pores, so that the material undergoes so-called gasification to change the friction angle of the material, so that it forms a flowing state and slides down along the slope to achieve the conveying purpose.

[0003] When the conveying chute is conveying, some larger particles are less affected by the wind force, which will affect the conveying efficiency. Moreover, the conveying efficiency is also related to the size of the wind force and the feeding rate. The output wind force and feeding rate of the existing conveying chute are fixed, and it is inconvenient for the wind force and the feeding rate to reach the balance of the maximum conveying efficiency. When the wind force is large, the wind force will blow the material to the top of the chute, affecting the conveying of the material. When the feeding is excessive and the wind force is small, the wind force is not enough to fluidize the material, resulting in a reduction in the conveying efficiency. Content of the Utility Model

[0004] The utility model provides an intelligent control cement air conveying chute, which has the advantage of automatically adjusting the cement feeding rate and the wind force size, so as to solve the problem that the existing air chute cannot adjust the wind force and the feeding efficiency, and the conveying efficiency cannot reach the maximum.

[0008] As a preferred technical solution of the present utility model, a baffle is installed at the front end of the screening drawer, and the baffle is located above the screen and cooperates with the screen.

[0009] As a preferred technical solution of the present utility model, the feeding speed regulating assembly includes an insertion plate embedded in the bottom of the feeding pipeline, a partition plate is installed in the insertion plate, a feeding chamber and a power chamber are respectively arranged on the front and rear sides of the partition plate, the feeding chamber cooperates with the feeding pipeline, a servo cylinder is installed at the outer end of the insertion plate, the end of the output shaft of the servo cylinder is installed with a movable plate and penetrates through the insertion plate and extends into the feeding chamber and the power chamber, and the movable plate penetrates through the partition plate and is movably connected with the partition plate.

The end of the output shaft of the servo cylinder 77 is installed with a movable plate 75 which penetrates the plug plate 71 and extends into the blanking chamber 74 and the power chamber 73. The movable plate 75 penetrates the partition plate 72 and is movably connected to the partition plate 72;

[0025] In this embodiment, the servo cylinder 77 can drive the movable plate 75 to move back and forth and insert into the feed pipe 5, so as to adjust the size of the space for the material to pass through in the blanking pipe 3, and further realize the adjustment of the material feeding rate.

[0028] Based on the above Embodiment 1, please refer to the appendix Figure 3 , appendix Figure 5 , the screening component 6 includes a screening drawer 61 embedded and detachably installed in the middle of the feed pipe 5. A screen 64 is installed in the screening drawer 61. The feed pipe 5 is provided with a disassembly and assembly groove 51 with three openings. The screening drawer 61 is movably connected and fitted with the disassembly and assembly groove 51. A plurality of disassembly and assembly plates 62 are symmetrically installed at the front end of the screening drawer 61. The disassembly and assembly plates 62 are provided with fixing holes 63.

[0030] Working principle and usage process of the utility model: Cement powder enters the material conveying chamber 12 in the tank body 1 from the feeding pipeline 5. At the same time, the air blowing device 2 conveys wind to the air chamber. After the wind in the air chamber passes through the breathable layer 14 to fluidize the powder in the material conveying chamber 12, the fluidized powder in the obliquely installed tank body 1 flows by gravity for conveying. When the powder flows to the blanking pipeline 3, it is discharged through the discharge pipe 31. When the powder passes through the discharge pipe 31, the powder flowmeter 32 monitors the flow rate of the powder to obtain the conveying efficiency of the powder. When the conveying efficiency of the powder is relatively low, the PLC controller 4 controls the servo cylinder 77 to start. The servo cylinder 77 drives the movable plate 75 to expand and contract. When the movable plate 75 extends, more parts of the movable plate 75 are inserted into the feeding pipeline 5, blocking the powder inlet to reduce the powder input rate. When the movable plate 75 retracts, fewer parts of the movable plate 75 are inserted into the feeding pipeline 5, widening the powder inlet and thus increasing the powder input rate. At the same time, the PLC controller 4 controls the voltage of the transformer of the air blowing device 2 to adjust the wind force of the air blowing device 2, and stops adjusting until the conveying efficiency data monitored by the powder flowmeter reaches the preset value.
