Description

Technical Field

[0001] This application relates to the technical field of preventing blockage in the discharging of a cement silo, and more particularly, to a structure for preventing blockage in the discharging of a cement silo. Background Art

[0002] A cement silo is a large container or tank for storing cement, which plays an important role in the construction industry, cement production plants and other fields. Among them, in cement production enterprises, the cement silo is used to store the finished cement produced for subsequent transportation and sales.

[0003] However, during the process of cement shipment, some cement is compacted in the silo due to long-term storage, forming a solid caking layer, which hinders the flow of materials, affects the normal shipment of cement, disrupts the originally arranged transportation vehicle scheduling plan, causes vehicle idleness or congestion, and increases transportation costs. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide a structure for preventing blockage in the discharging of a cement silo, which can solve the technical problems raised in the background art.

[0005] The embodiments of this application provide a structure for preventing blockage in the discharging of a cement silo, including a cement silo body. A support frame is fixedly arranged inside the cement silo body. A blowing component and a transmission component are rotatably arranged on the support frame. The blowing component is in transmission connection with the transmission component. A driving motor for driving the transmission component to rotate is arranged outside the cement silo body. An air supply component for supplying air to the blowing component is arranged on the cement silo body.

[0006] Further, the blowing component includes a conical blowing part and a connecting cylinder. The connecting cylinder is fixedly arranged at the bottom of the conical blowing part. The connecting cylinder is rotatably connected to the top of the support frame. An air cavity is arranged inside the conical blowing part.

[0012] Advantages of the present utility model:

[0013] In the present utility model, the drive motor drives the transmission component to rotate, thereby causing the blowing component to rotate.

[0026] For example Figure 1And Figure 2 As shown in the figure, the present application provides an anti-blocking structure for the discharge of a cement silo, which includes a cement silo body 1. A support frame 2 is fixedly arranged inside the cement silo body 1. A blowing component 3 and a transmission component 4 are rotatably arranged on the support frame 2. The blowing component 3 is in transmission connection with the transmission component 4. A driving motor 5 for driving the transmission component 4 to rotate is arranged outside the cement silo body 1. An air transmission component 6 for supplying air to the blowing component 3 is arranged on the cement silo body 1. The driving motor 5 drives the transmission component 4 to rotate, the transmission component 4 drives the blowing component 3 to rotate, and at the same time, air is supplied to the blowing component 3 through the air transmission component 6. The high-pressure air blown out by the blowing component 3 blows the caked cement in the cement silo body 1, so that the cement smoothly flows out from the discharge port of the cement silo body 1, ensuring the normal delivery of cement, avoiding disrupting the originally arranged transportation vehicle scheduling plan and causing vehicle idleness or congestion, and avoiding the increase in transportation costs.

[0027] As Figure 2 shown in the figure, the blowing component 3 includes a conical blowing part 31 and a connecting cylinder 32. The connecting cylinder 32 is fixedly arranged at the bottom of the conical blowing part 31. The connecting cylinder 32 is rotatably connected to the top of the support frame 2. An air cavity 311 is arranged inside the conical blowing part 31. An inclined blowing pipe 7 and an air transmission vertical pipe 8 communicating with the air cavity 311 are arranged on the conical blowing part 31. Specifically, during discharging, high-pressure air is conveyed to the blowing component 3 through the air transmission component 6. The high-pressure air enters the air cavity 311 through the air transmission vertical pipe 8 and then blows out from the inclined blowing pipe 7, loosening the caked cement in the cement silo body 1 and facilitating discharging.

[0028] As Figure 2 shown in the figure, the transmission component 4 includes a first bevel gear 41 and a transmission shaft 42. A second bevel gear 9 is fixedly arranged on the outer side of the connecting cylinder 32. The first bevel gear 41 meshes with the second bevel gear 9. The transmission shaft 42 is rotatably arranged on the support frame 2. The first bevel gear 41 is fixedly arranged at one end of the transmission shaft 42. The other end of the transmission shaft 42 extends outside the cement silo body 1 and is connected to the output shaft of the driving motor 5. Specifically, the driving motor 5 drives the transmission shaft 42 to rotate, the transmission shaft 42 drives the first bevel gear 41 to rotate, the first bevel gear 41 drives the second bevel gear 9, the second bevel gear 9 drives the connecting cylinder 32, and the connecting cylinder 32 drives the conical blowing part 31 to rotate, so that the direction of the high-pressure air blown by the conical blowing part 31 rotates, increasing the contact area between the high-pressure air and the caked cement in the cement silo body 1 and improving the loosening effect.

[0029] As Figure 2As shown in the figure, the gas transmission assembly 6 includes a gas transmission valve 61, a gas transmission pipe 62, and a flexible pipe fitting 63. The gas transmission pipe 62 is fixedly arranged at the bottom of the support frame 2. One end of the gas transmission pipe 62 is movably and hermetically connected to the gas transmission vertical pipe 8 through the flexible pipe fitting 63. The other end of the gas transmission pipe 62 extends outside the cement silo body 1. The gas transmission valve 61 is arranged on the gas transmission pipe 62 and is located outside the cement silo body 1. Specifically, gas is transmitted to the gas transmission vertical pipe 8 through the gas transmission pipe 62. The gas transmission valve 61 controls the opening and closing of the gas transmission pipe 62 to control the gas transmission to the gas transmission vertical pipe 8. The flexible pipe fitting 63 belongs to the prior art and is used for movably and hermetically connecting to the gas transmission vertical pipe 8 to enable the gas transmission vertical pipe 8 to rotate. Among them, the gas transmission vertical pipe 8 is located inside the connecting cylinder 32, and the spatial layout is reasonable.

[0030] As Figure 2 shown in the figure, the conical blowing part 31 is located directly above the feeding port of the cement silo body 1. The conical blowing part 31 can make the cement in the cement silo body 1 fall around and then flow out from the feeding port of the cement silo body 1, avoiding the accumulation situation caused by the cement concentrating and falling from the middle of the feeding port of the cement silo body 1.

[0031] As Figure 2 shown in the figure, the inclined blowing pipe 7 is balanced with the inclined wall of the conical blowing part 31. The air outlet end of the inclined blowing pipe 7 is located above the transmission shaft 42 to ensure the effective blowing angle and blowing direction of the inclined blowing pipe 7.

[0032] As Figure 2 shown in the figure, there are two inclined blowing pipes 7, and the two inclined blowing pipes 7 are symmetrically arranged. The arrangement of the two inclined blowing pipes 7 improves the blowing efficiency and the cement feeding speed.

[0033] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
