Description

Technical Field

[0001] This application relates to the field of conveyors, and more specifically, to a feeding conveyor for a cement raw material batching station. Background Technology

[0002] Cement is a powdery hydraulic inorganic binder that, when mixed with water, forms a paste that hardens in air or water, and can firmly bind materials such as sand and stone together. Cement is prepared by mixing calcareous raw materials (such as limestone) and clayey raw materials (such as clay and shale) in appropriate proportions, followed by grinding and other processes. Currently, in the cement production process, cement raw materials need to be transported into the production equipment. Conveyors are generally used for this, but sometimes material blockage occurs during the feeding process, requiring operators to clear the blockages, which is inconvenient. Summary of the Invention

[0026] This application discloses a feeding conveyor for a cement raw material batching station.

[0027] Reference Figure 1-3 The system includes a frame 1, on which a conveyor belt 11 is horizontally mounted. Two parallel guide rollers are also horizontally mounted on the frame 1, with their ends rotatably supported on the frame 1. The conveyor belt 11 is wrapped around and connected to the two guide rollers. A motor is fixedly mounted horizontally on the frame 1, with its output shaft connected to the axis of one of the guide rollers. When the motor operates, it drives the guide roller to rotate, thereby driving the conveyor belt 11. Additionally, a feed inlet 2 is provided on the frame 1, connected to the cement production equipment. The feed inlet 2 is located directly below the discharge end of the conveyor belt 11. After the conveyor belt 11 delivers raw cement, the raw cement falls from the discharge end of the conveyor belt 11 into the feed inlet 2. Meanwhile, multiple rollers 12 are provided on both sides of the conveyor belt 11. These rollers 12 are spaced apart along the conveying direction of the conveyor belt 11 and are inclined. The bottom end of each roller 12 is rotatably supported by the frame 1, and the circumferential surface of the roller 12 is in contact with the upper inner side of the conveyor belt. The upper sides of the conveyor belt 11 are bent upwards. Due to the flexibility of the conveyor belt 11, it deforms under the guidance of the rollers 12, causing the sides of the conveyor belt 11 to bend. This design prevents raw material from falling off the sides of the conveyor belt 11 during transport. Additionally, baffles 13 are provided on both sides of the conveyor belt 11 and are fixedly connected to the frame 1. The upper side of the conveyor belt 11 is located between the baffles 13 and the rollers 12. When the conveyor belt 11 is loaded, the baffles 13 prevent raw material from falling off.

[0028] Additionally, an air tank 3 is fixedly installed on the frame 1. The air tank 3 is connected to an air pump and an air jet pipe 31. The air outlet of the air jet pipe 31 faces the feed inlet 2. An air inlet valve is provided between the air pump and the air tank 3, and an air outlet valve is provided between the air jet pipe 31 and the air tank 3. Both the air inlet valve and the air outlet valve can preferably be solenoid valves. When the air inlet valve is opened, the air pump operates to inflate the air tank 3. After inflation is complete, the air inlet valve is closed. When raw material blocks the feed inlet 2, the air outlet valve opens, and the high-pressure air in the air tank 3 is sprayed through the air jet pipe 31 into the feed inlet 2, clearing away the blocked raw material in the feed inlet 2. This eliminates the need for manual cleaning. Furthermore, the air tank 3 allows for the pre-storage of a large amount of air, increasing the air jet volume. Meanwhile, a conical flared sleeve 32 is provided at the air outlet end of the jet pipe 31. The small end of the conical flared sleeve 32 is connected to the air outlet end of the jet pipe 31 by welding, and the large end of the conical flared sleeve 32 faces the feed inlet 2. The conical flared sleeve 32 can guide the air ejected from the jet pipe 31 to a certain extent, so that the air can better clean the blocked raw material.

[0029] In addition, a baffle 4 is fixedly installed on the frame 1. The baffle 4 is open and the discharge end of the conveyor belt 11 is located inside the baffle 4. The large end of the conical flared sleeve 32 is connected to the top of the baffle 4. The baffle 4 can play a certain blocking role. When raw material is falling or when cleaning blockages, dust will be generated. The baffle 4 can reduce the emission of dust and is more environmentally friendly. Additionally, a guide plate 41 is provided on the top of the inner wall of the baffle 4. The top side of the guide plate 41 is hinged to the top of the inner wall of the baffle 4. A cylinder 42 is provided inside the baffle 4. One end of the cylinder 42 is hinged to the top of the inner wall of the baffle 4. The piston rod of the cylinder 42 is hinged to one side surface of the guide plate 41. When the piston rod of the cylinder 42 extends, the guide plate 41 is located in the air outlet direction of the jet pipe 31. When clearing blockages, the piston rod of the cylinder 42 extends, causing the guide plate 41 to rotate and move to the air outlet direction of the jet pipe 31. The air ejected from the jet pipe 31 blows onto the guide plate 41, and the guide plate 41 guides the airflow, causing the airflow to blow onto the side wall of the feed inlet 2, thereby blowing off some raw material adhering to the side wall of the feed inlet 2. In addition, multiple support rods are connected between the piston rod of the cylinder 42 and one side surface of the guide plate 41. The support rods can improve the connection strength between the piston rod of the cylinder 42 and the guide plate 41.

[0030] The implementation principle of the cement raw material batching plant feeding conveyor in this application embodiment is as follows: the air pump works to fill the air tank 3 with air. After the air filling is completed, the air inlet valve is closed. When the raw material blocks the feed inlet 2, the air outlet valve is opened. The high-pressure air in the air tank 3 is sprayed into the feed inlet 2 through the jet pipe 31, which flushes away the blocked raw material in the feed inlet 2, so that manual cleaning is not required, which is convenient and quick.

[0031] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
