Description

Technical Field

[0001] The utility model relates to the technical field of coal powder storage, in particular to an automatic bin cutting device for storing multiple coal powder bins. Background Art

[0002] Pulverized coal delivery is a crucial step in coal storage. Its convenience and safety are crucial to its efficiency and smooth flow. Accurate delivery of pulverized coal into specific silos and the unimpeded flow of each pipeline must be ensured. Accurate delivery of pulverized coal depends on the switching and coordination of valves, while the unimpeded flow of each pipeline depends on the adequate sealing of each closed valve.

[0003] The existing cutting-bin valve has the problem of loose sealing in the closed state, and coal powder easily leaks and blocks the pipeline. The blocked pipeline needs to be cleaned regularly, which reduces the working efficiency of the entire device and increases a lot of costs. The leaked coal powder easily pollutes the environment, and the overall safety performance is poor.

[0004] To this end, we propose a multi-powder storage automatic bin cutting device. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Multi-bin automatic cutting device for powder storage, such as Figure 1As shown, it includes a pulverized coal bunker 10, a pulverized coal bunker pipe is fixedly installed on the top of the pulverized coal bunker 10, a pulverized coal input pipe 11 is fixedly installed on the top of the pulverized coal bunker pipe, a two-way valve 12 is fixedly installed on the outer wall of the pulverized coal input pipe 11, the two-way valve 12 includes a valve body, a valve stem 13 and a valve core 14 are provided inside the valve body, an upper output end anti-blocking plug valve 15 is fixedly installed on the upper output end anti-blocking plug valve 15, and a pulverized coal output pipe 18 is fixedly installed on the left wall of the upper output end anti-blocking plug valve 15. A lower output end anti-blocking gate valve 16 is fixedly installed at the lower output end of the valve 12, and the bottom of the lower output end anti-blocking gate valve 16 is fixedly connected to the coal powder bunker pipeline. A silo top gate valve 17 is provided on the outer wall of the coal powder bunker pipeline. A radar level meter 19 is provided on the top right side of the coal powder bunker 10. The end of the radar level meter 19 away from the coal powder bunker 10 is connected to the PLC control system 20 through an electrical signal, and the end of the PLC control system 20 away from the radar level meter 19 is connected to the two-way valve 12 through an electrical signal.

[0024] Example 2: Based on Example 1, Figure 1 As shown, the two-way valve 12 and the radar level meter 19 are interlocked via a PLC control system 20, automatically switching the valve path of the two-way valve 12. The upper output anti-blocking gate valve 15, the lower output anti-blocking gate valve 16, and the valve stem 13 form a dual safety device to prevent the flow of pulverized coal. The valve core 14 and the valve stem 13 form the device that controls the opening and closing of the upper and lower output ends of the two-way valve 12. The radar level meter 19 monitors the pulverized coal level in the pulverized coal bin 10 in real time and sends a signal to the PLC control system 20.

[0025] Example 3: Based on Example 1 and Example 2, Figure 1 As shown, the two-way valve 12, the upper output anti-blocking gate valve 15, the lower output anti-blocking gate valve 16, and the silo top gate valve 17 all utilize integrated intelligent sensors and control modules, enabling remote monitoring and automated control. These valves are constructed from new, high-strength, corrosion-resistant materials, extending their service life and reliability. The sealing design of these valves ensures extremely low leakage, reducing energy waste and environmental pollution.

[0026] The working principle of the present invention is as follows: when in use, pulverized coal enters the pulverized coal input pipe 11 and reaches the two-way valve 12. At this time, the valve stem 13 is in a vertical state, the upper output end anti-blocking gate valve 15 is closed, the lower output end anti-blocking gate valve 16 and the silo top gate valve 17 are opened, and the pulverized coal is injected into the pulverized coal bin 10. The previous two-way valve 12 did not have an upper output end anti-blocking gate valve 15. Therefore, when injecting pulverized coal into the bin, due to the large impact of the pulverized coal, there was a gap between the valve stem 13 and the valve body. The pulverized coal would leak through the valve stem 13 and accumulate in the pulverized coal output pipe 18, causing the pipe to be eventually blocked. The present invention installs an upper output end anti-blocking gate valve 15 close to the two-way valve 12, which realizes secondary blocking of the pulverized coal and ensures the smooth flow of the pulverized coal output pipe 18. When the radar level meter 19 detects that the pulverized coal has reached the preset height of the pulverized coal bin 10, it sends a signal to the PLC control system. 20 sends a signal, and the PLC control system 20 controls the valve core 14 to drive the valve stem 13 to rotate to a horizontal state. At this time, the upper output end anti-blocking gate valve 15 is opened, and the lower output end anti-blocking gate valve 16 and the silo top gate valve 17 are closed. The pulverized coal passage path is changed from pulverized coal input pipeline 11 - two-way valve 12 - lower output end anti-blocking gate valve 16 - silo top gate valve 17 - pulverized coal silo 10 to pulverized coal input pipeline 11 - two-way valve 12 - upper output end anti-blocking gate valve 15 - pulverized coal output pipeline 18. The lower output end anti-blocking gate valve 16 has the same function as the upper output end anti-blocking gate valve 15, effectively preventing the two-way valve 12 from the silo top gate valve 17 to be blocked by pulverized coal. When multiple pulverized coal silos need to be filled in sequence, the pulverized coal output pipeline 18 can be regarded as the pulverized coal input pipeline 11 of the rear flour silo. This layout can be replicated and arranged, and ultimately, automatic silo switching for multiple pulverized coal silos can be achieved.

[0027] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
