Description

Technical Field

[0001] This application relates to the field of cement production equipment technology, and more specifically, to a clinker silo bottom dust removal device. Background Technology

[0002] Clinker silos are large storage facilities used to store cement clinker. When clinker is unloaded and transported at the bottom of the silo, a large amount of dust is generated. If this dust is not treated, it will be released into the atmosphere, causing serious pollution to the surrounding environment. In addition, workers at the bottom of the clinker silo are exposed to high concentrations of dust for a long time, which can easily lead to respiratory diseases, pneumoconiosis and other occupational diseases, seriously endangering the health of the workers.

[0003] Chinese Patent Publication No. CN215100674U discloses a dust collection device for cement clinker silos, including a clinker silo. A dust collection device is installed at the bottom of the clinker silo. The dust collection device includes a discharge pipe, a discharge valve assembly on the discharge pipe, a chute below the discharge valve assembly, and a dust suction hood below the chute. A dust outlet is provided on one side of the clinker silo, and a first dust outlet pipe is installed on the dust outlet. One end of the first dust outlet pipe is connected to the dust suction hood, and the other end of the first dust outlet pipe is connected to a bag filter. One end of the bag filter is connected to a variable frequency fan through a second dust outlet pipe, and one end of the variable frequency fan is connected to a third dust outlet pipe. The baghouse dust collectors installed on one side of the clinker silo have a larger air volume, resulting in a wider dust collection range and better dust collection effect. The variable frequency fan installed in the same way can adjust the air volume according to the dust conditions on site to meet the dust collection needs of the clinker silo under different working conditions. The dust hoods are used to surround the vehicle body during the loading process to prevent excessive dust from being blown out during loading, which enhances the dust collection effect.

[0004] The aforementioned device features a dust hood positioned below the chute to enclose the cargo compartment of the loading vehicle. Clinker passes through the hood and is then loaded onto the vehicle. For ease of installation, the dust hood is made of an elastic material. However, in actual use, the dust hood presents several problems. Workers need to pull the lower end of the hood to enclose the cargo compartment; after loading, they must use tools to lift the lower end of the hood upwards to allow the vehicle to leave. This process significantly increases the workload and operational difficulty for workers, severely impacting work efficiency, especially when loading vehicles frequently enter and exit to transport clinker. Summary of the Invention

[0005] The purpose of this application is to provide a clinker silo bottom dust removal device, which can solve the technical problem that, in actual use, the dust collection device of the existing cement clinker silo dust collection device requires the staff to manually pull the lower end of the cover to load the truck bed, and after loading, the lower end needs to be supported with tools to allow the vehicle to leave. This not only increases the workload and difficulty of operation for the staff, but also seriously affects the work efficiency.

[0030] like Figure 1-3As shown, this application provides a clinker silo bottom dust removal device, including a feeding assembly 1, a dust collection assembly 2, a dust collection pipe 3, and a lifting and adjusting assembly 4. The feeding assembly 1 is used to connect to the feeding port at the bottom of the clinker silo. The dust collection assembly 2 includes a connecting plate 21, a surrounding cloth 22, and a movable frame 23. The connecting plate 21 is connected to the feeding assembly 1, and the movable frame 23 is located below the connecting plate 21. The connecting plate 21 is connected to the movable frame 23 through the surrounding cloth 22. The connecting plate 21, the surrounding cloth 22, and the movable frame 23 form a dust collection hood, which can concentrate dust in the dust collection hood. To improve dust collection efficiency, one end of the dust collection pipe 3 is connected to the connecting plate 21 and extends into the dust collection hood. The other end of the dust collection pipe 3 is connected to external dust removal equipment, enabling timely discharge of dust from the dust collection hood to the external dust removal equipment. The lifting and adjusting component 4 is located at the bottom of the clinker silo and is used to adjust the height of the moving frame 23, thereby adapting to loading vehicles of different heights and improving the versatility and flexibility of the device. Compared with existing technologies, when loading vehicles frequently enter and exit to load clinker, it effectively reduces the workload and operational difficulty of workers and improves work efficiency.

[0031] like Figure 3 As shown, the feeding assembly 1 includes a feeding chute 11 and a feeding valve 12. Specifically, the upper end of the feeding chute 11 is provided with a connecting flange. The feeding chute 11 is connected to the bottom feeding port of the clinker silo through the connecting flange, ensuring that the clinker can flow smoothly out of the clinker silo for feeding operation. The lower end of the feeding chute 11 passes through the connecting plate 21. The feeding valve 12 is provided on the feeding chute 11. The setting of the feeding valve 12 can control the feeding speed and flow rate, which can be adjusted according to actual needs.

[0032] like Figure 1-3 As shown, the lifting and adjusting assembly 4 includes a drive motor 41, a screw 42, a lifting frame 43, a guide rod 44, and a mounting frame 45. The drive motor 41 is located on one side of the moving frame 23. One end of the screw 42 is connected to the output shaft of the drive motor 41. The upper ends of the drive motor 41 and the guide rod 44 are fixed to the bottom of the clinker silo via the mounting frame 45. Specifically, the drive motor 41 is fixed to the bottom of the mounting frame 45, and the upper end of the guide rod 44 is fixedly connected to the bottom of the mounting frame 45. The mounting frame 45 has fixing holes, through which expansion bolts can be used to adjust the lifting mechanism. The mounting frame 45 is fixed at the bottom of the clinker silo, and the guide rod 44 is located on the other side of the moving frame 23. The lower end of the screw 42 and the lower end of the guide rod 44 both movably pass through the lifting frame 43. The screw 42 is threadedly connected to the lifting frame 43, and the moving frame 23 is connected to the lifting frame 43. The screw 42 is driven to rotate by the drive motor 41, which drives the lifting frame 43 and the guide rod 44 to move stably upward or downward, thereby driving the moving frame 23 to move upward or downward. When the loading vehicles frequently enter and exit to load clinker, the height of the moving frame 23 can be quickly adjusted to improve work efficiency.

[0033] like Figure 1 and Figure 2 As shown, a set of reinforcing ribs 5 are fixed at the connection between the connecting plate 21 and the discharge chute 11.
