Description

Technical Field

[0001] This utility model relates to the field of coal processing, and in particular to a pulse anti-blocking interconnected compartment for peak shaving and distribution. Background Technology

[0002] The raw coal bunker partitioning technology involves modifying the raw coal bunker into separate compartments to enable rapid blending of different coal types, thus meeting the peak-shaving demands of rapidly changing loads throughout the day. This technology improves the accuracy of load response, allowing high-calorific-value coal to be burned during high loads and low-calorific-value coal during low loads, thereby enhancing the unit's peak-shaving capacity. Research and application of raw coal bunker anti-blockage technology mainly addresses the problems of coal bridging and blockage in raw coal bunkers.

[0003] Traditional pulse anti-blocking interconnection bins for segmented peak shaving may not completely solve the problem of coal powder adhesion and blockage in the coal bins, especially under high load or large changes in coal quality, the blockage problem may still exist. In terms of regulating coal quality and quantity, segmented peak shaving technology may lack sufficient flexibility and is difficult to adapt to rapid changes in grid load. Therefore, those skilled in the art have provided a pulse anti-blocking interconnection bin for segmented peak shaving to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pulse anti-blocking interconnected compartment for peak shaving and distribution. Using an anti-blocking structure composed of two motors, a screw rod, and two gate valves, it effectively prevents coal blockage. When the gate valve of one compartment opens, the gate valve of the other compartment closes, and the motor drives the screw rod to rotate, promoting coal flow and thus preventing blockage. This design not only improves coal flowability but also extends the service life of the equipment. Through a fixed block, electric telescopic rod, connecting rod, chute, and U-shaped channel, precise adjustment of the feed openings for high-quality and low-quality coal can be achieved. The telescopic movement of the electric telescopic rod, through the cooperation of the connecting rod and the chute, drives the U-shaped channel to move, thereby adjusting the feed opening. This design improves the flexibility and accuracy of feed opening adjustment. The protective frame, support rod, and mounting block not only protect the base and the equipment above but also ensure the stability of the protective frame. By setting threaded joints on the mounting block, the protective structure can be fixedly connected to other components, ensuring its stability during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pulse anti-blocking interconnection compartment for peak regulation, comprising a base, an anti-blocking structure at the center of the base, a first compartment located at one side of the center of the upper end face of the base, a second compartment located at the other side of the center of the upper end face of the base, an adjustment structure located at both sides of the center of the base, a protective structure located at the center of the lower end face of the base, a coal discharge port located at the center of the lower end face of both the first and second compartments, and multiple pulse anti-blocking devices located at the lower center of the outer walls of both the first and second compartments;

[0006] The above technical solution, using an anti-clogging structure composed of two motors, a screw rod, and two gate valves, effectively prevents coal blockage. When the gate valve of one compartment is opened, the gate valve of the other compartment is closed, and the motor drives the screw rod to rotate, promoting coal flow and thus avoiding blockage. This design not only improves coal flowability but also extends the service life of the equipment. Through fixed blocks, electric telescopic rods, connecting rods, chutes, and U-shaped channels, precise adjustment of the feed openings for high-quality and low-quality coal can be achieved. The telescopic movement of the electric telescopic rod, through the cooperation of the connecting rod and the chutes, drives the U-shaped channel to move, thereby adjusting the feed opening. This design improves the flexibility and accuracy of feed opening adjustment. The protective frame, support rods, and mounting blocks not only protect the base and the equipment above but also ensure the stability of the protective frame. By setting threaded openings on the mounting blocks, the protective structure can be fixedly connected to other components, ensuring its stability during use.

[0007] Furthermore, the anti-blocking structure includes two motors, a screw rod, and two gate valves. The two motors are respectively located at the center of the two side walls of the base, and the screw rod is located at the center of the base. The output ends of the two motors pass through the two side walls of the base and extend into the base, and their ends are respectively fixedly connected to one end of the two screw rods. The two gate valves are respectively located at the upper end of the base near the center of the outer side wall of the first and second compartments.

[0008] With the above technical solution, when the gate valve of No. 1 bin is opened and the gate valve of No. 2 bin is closed, the regulating structure pushes the high-quality coal inside No. 1 bin to fall. The starting motor drives the screw rod to rotate, which in turn drives the screw blade to rotate and push the high-quality coal to flow through the two coal discharge ports. When the regulating structure is closed, the screw rod stops conveying coal, which disturbs the high-quality coal to prevent blockage. Similarly, when the gate valve of No. 2 bin is opened and the gate valve of No. 1 bin is closed, the motor reverses and discharges the low-quality coal through the two coal discharge ports.

[0009] Furthermore, the two adjustment structures include a fixed block, two electric telescopic rods, two connecting rods, two sliding grooves, and two U-shaped grooves. The fixed block is located at the center of the upper end face of the base. The two electric telescopic rods are respectively located on both sides of the center inside the fixed block. The two connecting rods are respectively located on the output ends of the two electric telescopic rods. The two sliding grooves are respectively located on both sides of the rear of the upper end face of the base. The two U-shaped grooves are respectively located on both sides of the center inside the base. One end of each of the two connecting rods passes through the upper end face of the two sliding grooves and extends into the interior of the base, and the ends are respectively fixedly connected to the upper end face of the two U-shaped grooves.

[0010] With the above technical solution, when the feed opening needs to be adjusted, the electric telescopic rod receives a control signal and starts working. The electric telescopic rod extends and retracts, driving the connecting rod to move. The connecting rod slides in the chute to ensure the stability of the direction of movement. When the connecting rod moves, it drives the U-shaped chute to move, thereby realizing the adjustment of the feed opening for high-quality coal and low-quality coal.

[0011] Furthermore, the protective structure includes a protective frame, four support rods, and four mounting blocks. The protective frame is disposed on the lower end face of the base, the four support rods are arranged in a rectangular pattern on the upper end face of the protective frame, and the four mounting blocks are respectively disposed at the upper center of the outer side wall of the four support rods.

[0012] Through the above technical solution, the protective frame, as the main protective component, plays the role of protecting the base and the equipment above it. The support rod plays the role of supporting and reinforcing the protective frame to ensure its stability. The mounting block can be used to connect the protective structure with other components or to fix the position of the protective structure.

[0013] Furthermore, each of the four mounting blocks has four threaded openings arranged in a rectangular pattern on its upper surface;

[0014] By using the above technical solution, the protective structure can be fixedly connected to other components by screwing bolts and other connecting parts into the threaded opening, ensuring that the protective structure maintains a stable position during use.

[0015] Furthermore, the two U-shaped grooves are respectively adapted to the protective structure and the second compartment;

[0016] The above technical solutions ensure smooth coal flow and accurate adjustment of the feed inlet.

[0017] Furthermore, the two connecting rods are slidably connected inside the two sliding grooves respectively;

[0018] With the above technical solution, when the electric telescopic rod extends or retracts, it drives the connecting rod to slide in the chute, thereby changing the position of the U-shaped chute and adjusting the material inlet.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the pulse anti-blockage interconnection compartment for peak shaving uses an anti-blockage structure composed of two motors, a screw rod, and two gate valves to effectively prevent coal blockage. When the gate valve of one compartment is opened, the gate valve of the other compartment is closed, and the motor drives the screw rod to rotate, promoting the flow of coal and thus avoiding blockage. This design not only improves the fluidity of coal but also extends the service life of the equipment.

[0021] 2. In this utility model, the precise adjustment of the feed opening for high-quality coal and low-quality coal can be achieved through the fixed block, electric telescopic rod, connecting rod, slide chute and U-shaped chute. The telescopic movement of the electric telescopic rod, through the cooperation of the connecting rod and slide chute, drives the U-shaped chute to move, thereby realizing the adjustment of the feed opening. This design improves the flexibility and accuracy of feed opening adjustment.

[0022] In this utility model, the protective frame, support rod, and mounting block not only protect the base and the equipment above, but also ensure the stability of the protective frame. By setting threaded holes on the mounting block, the protective structure can be fixedly connected to other components to ensure its stability during use. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-4 This utility model provides an embodiment of a pulse anti-blocking interconnected compartment for peak shaving, comprising a base 1, an anti-blocking structure 2 at the center of the base 1, a first compartment 4 located on one side of the center of the upper end face of the base 1, a second compartment 5 located on the other side of the center of the upper end face of the base 1, adjustment structures 6 located on both sides of the center of the base 1, a protective structure 3 located at the center of the lower end face of the base 1, and coal discharge ports 7 located at the center of the lower end faces of both the first compartment 4 and the second compartment 5. Multiple pulse anti-blocking devices 8 are installed at the lower center. The anti-blocking structure 2 is used to prevent coal from accumulating and blocking inside the bin. When the anti-blocking structure 2 is activated, it maintains the normal flow of coal. No. 1 bin 4 and No. 2 bin 5 are used to store coal of different qualities or to store and distribute coal at different times. The coal discharge port 7 can control the discharge of coal. The regulating structure 6 is used to adjust the direction of coal discharge in No. 1 bin 4 and No. 2 bin 5. The protective structure 3 provides protection for the entire equipment. The coal discharge port 7 is used to control the discharge of coal.

[0031] The anti-blocking structure 2 includes two motors 201, a screw rod 202, and two gate valves 203. The two motors 201 are respectively located at the center of the two side walls of the base 1, and the screw rod 202 is located at the center of the interior of the base 1. The output ends of the two motors 201 pass through the two side walls of the base 1 and extend into the interior of the base 1, with their ends fixedly connected to one end of each screw rod 202. The two gate valves 203 are respectively located at the lower center of the outer side walls of compartment 4 and compartment 5, on the upper end of the base 1. When the gate valve 203 of compartment 4 opens... When gate valve 203 of No. 2 bin 5 is closed, regulating structure 6 pushes the high-quality coal inside bin 4 to fall. By starting motor 201, it drives screw rod 202 to rotate, causing screw rod 202 to drive the screw blade to rotate and push the high-quality coal to flow through the two coal discharge ports 7. When regulating structure 6 is closed, screw rod 202 does not transport coal, which disturbs the high-quality coal to prevent blockage. Similarly, when gate valve 203 of No. 2 bin 5 is opened, gate valve 203 of bin 4 is closed, and motor 201 reverses to discharge low-quality coal through the two coal discharge ports 7.

[0032] The two adjustment structures 6 include a fixed block 601, two electric telescopic rods 602, two connecting rods 603, two sliding grooves 604, and two U-shaped grooves 605. The fixed block 601 is located at the center of the upper end face of the base 1. The two electric telescopic rods 602 are respectively located on both sides of the center inside the fixed block 601. The two connecting rods 603 are respectively located on the output ends of the two electric telescopic rods 602. The two sliding grooves 604 are located on both sides of the rear of the upper end face of the base 1. The two U-shaped grooves 605 are respectively located on both sides of the center inside the base 1. One end of each connecting rod 603 passes through the upper end face of the two sliding grooves 604 and extends into the interior of the base 1, and the ends are respectively fixedly connected to the upper end face of the two U-shaped grooves 605. When needed... When adjusting the feed opening, the electric telescopic rod 602 receives a control signal and starts working. The electric telescopic rod 602 extends and retracts, driving the connecting rod 603 to move. The connecting rod 603 slides within the chute 604 to ensure stable movement. When the connecting rod 603 moves, it drives the U-shaped chute 605 to move, thereby adjusting the feed opening for high-quality coal and low-quality coal. The two connecting rods 603 are slidably connected inside the two chute 604 respectively. When the electric telescopic rod 602 extends and retracts, it drives the connecting rod 603 to slide within the chute 604, thereby changing the position of the U-shaped chute 605 and adjusting the feed opening. The two U-shaped chute 605 are respectively adapted to the protective structure 3 and the second bin 5 to ensure smooth coal flow and accurate adjustment of the feed opening.

[0033] The protective structure 3 includes a protective frame 301, four support rods 302, and four mounting blocks 303. The protective frame 301 is located on the lower end face of the base 1. The four support rods 302 are arranged in a rectangular pattern on the upper end face of the protective frame 301. The four mounting blocks 303 are respectively located at the upper center of the outer side wall of the four support rods 302. The protective frame 301, as the main protective component, is responsible for protecting the base 1 and the equipment above it. The support rods 302 support and reinforce the protective frame 301 to ensure its stability. The mounting blocks 303 can be used to connect the protective structure 3 to other components or to fix the position of the protective structure 3. The upper end face of each of the four mounting blocks 303 is arranged in a rectangular pattern and has four threaded holes. By screwing bolts or other connecting parts into the threaded holes, the protective structure 3 can be fixedly connected to other components to ensure that the protective structure 3 maintains a stable position during use.

[0034] Working principle: When gate valve 203 of No. 1 bin 4 is opened and gate valve 203 of No. 2 bin 5 is closed, the electric telescopic rod 602 extends and retracts, driving the connecting rod 603 to move. The connecting rod 603 slides in the chute 604, causing the U-shaped chute 605 to move to the coal discharge port 7. Half of the coal is discharged directly through the coal discharge port 7, while the other half of the coal is discharged through the starting motor 201, which drives the screw rod 202 to rotate. The screw rod 202 drives the spiral blades to rotate, pushing the high-quality coal to flow through the two coal discharge ports 7. When the regulating structure 6 is closed, the screw rod 202 stops conveying coal. The coal feeding mechanism disturbs the high-quality coal to prevent blockage. Similarly, when gate valve 203 of No. 2 bin 5 is opened, gate valve 203 of No. 1 bin 4 is closed, and motor 201 reverses, allowing the low-quality coal to be discharged through the two coal discharge ports 7. The protective frame 301, as the main protective component, is responsible for protecting the base 1 and the equipment above it. The support rod 302 supports and reinforces the protective frame 301 to ensure its stability. The mounting block 303 can be used to connect the protective structure 3 to other components or to fix the position of the protective structure 3.

[0035] A pulse-based anti-clogging interconnected compartment for peak shaving is described. The anti-clogging system involves compressed air entering the pulse anti-clogging device 8 and being momentarily opened by a pulse valve. The airflow enters the pulse anti-clogging component, lifting the umbrella rod and spraying the airflow along the outer circumference of the sleeve to clean the inner wall of the container. A perforated nut and a flange nut clamp the component to the compartment body through a spacer, providing mechanical fixation. When the pulse valve closes, the umbrella rod quickly returns to its seat due to the spring force, achieving a sealing effect.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
