Description

Technical Field

[0001] This utility model relates to the technical field of dust collector ash hopper conveying devices, specifically a multi-tube dust collector ash hopper ash storage and conveying device. Background Technology

[0002] The ceramic multi-tube dust collector is a type of cyclone dust collector. When dust-laden gas enters the dust collector, it passes through a ceramic guide and rotates at high speed inside the cyclone. Under the action of centrifugal force, dust and gas are separated. The dust falls into the dust collection box and is discharged through the ash discharge valve. The purified gas forms an upward vortex, which flows through the exhaust pipe into the gas collection chamber and is discharged through the outlet, achieving the dust removal effect. The separated impurities are subsequently concentrated and accumulated at the bottom of the ash hopper. The material conveying pump is a low-pressure dilute phase powder pneumatic conveying equipment, belonging to the special devices for short and medium distance powder conveying in the fields of power, building materials, and chemical industry. It is mainly used for conveying dry and loose materials such as fly ash, cement, and alumina powder. Therefore, when the dust accumulated at the bottom of the ceramic multi-tube dust collector is centrally conveyed, a material conveying pump is connected to the ash hopper at the bottom of the multi-tube dust collector for conveying.

[0003] However, since the dust in the ash hopper is discharged all at once after the multi-tube dust collector is shut down, the dust accumulated in the ash hopper is directly poured into the input end of the material sealing pump. This direct feeding at once makes it easier for the material sealing pump input end to accumulate, exceeding the conveying threshold and affecting normal discharge. In addition, a large amount of dust is now easily attached to the inner wall of the ash hopper, which can easily lead to incomplete discharge. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a multi-tube dust collector ash hopper ash conveying device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-tube dust collector ash hopper conveying device, comprising a multi-tube dust collector housing, an ash hopper installed at the bottom of the multi-tube dust collector housing, a material sealing pump connected to the bottom discharge port of the ash hopper, two symmetrically arranged baffles movably inserted at the bottom of the ash hopper, connecting blocks fixed at both ends of the baffles outside the ash hopper, a protective cover fixedly installed on the outer wall of the ash hopper between the two connecting blocks, and a drive gear rotatably installed at the middle end inside the protective cover, diagonally arranged toothed plates sliding inside the protective cover, both toothed plates meshing and connected to the drive gear, the ends of the two toothed plates away from the drive gear fixedly installed on adjacent connecting blocks, symmetrically arranged rotating rods rotatably installed above the baffles inside the ash hopper, and a spiral stirring component fixedly installed on the rotating rods; an electric push rod fixedly installed on the lower surface of the outer wall of the protective cover, and the output end of the electric push rod fixedly installed on one of the connecting blocks.

[0006] Preferably, the outer wall of the ash hopper is fixedly provided with an inverted L-shaped connecting plate on both sides adjacent to the first motor. The upper end of the connecting plate is rotatably provided with a swing plate. The swing plate is fixedly provided with a plurality of equally spaced striking rods on the side facing the ash hopper. The bottom of the connecting plate is provided with a groove. A movable plate is horizontally slidable in the groove. The movable plate and the swing plate are hinged together with a connecting rod. The middle end of the movable plate is provided with a movable groove. A push block is movably inserted in the movable groove. The upper end of the push block is fixedly provided with a horizontally arranged rotating plate. The end of the rotating plate away from the push block is fixedly provided with a vertically arranged rotating shaft. The rotating shaft is rotatably arranged in the connecting plate. Both ends of the movable plate are fixedly provided with long plates, and the long plates are movably inserted in the groove.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. In this utility model, two baffles are driven by an electric push rod to open and close intermittently, so as to realize the intermittent discharge of dust in the ash hopper. The opening range and time of the baffles can be controlled each time, ensuring that the amount of dust entering the material sealing pump each time is within its conveying threshold. This avoids the situation where the material sealing pump is piled up at the input end and exceeds the conveying threshold due to direct feeding at one time, thus ensuring the normal conveying of the material sealing pump and maintaining the stable operation of the discharge link.

[0009] 2. In this utility model, while the electric push rod is working to achieve intermittent material discharge, the first motor starts and drives the rotating rod to rotate through the transmission gear. The spiral stirring component on the rotating rod rotates accordingly, which can stir the dust accumulated above the baffle, keep the dust in a flowing state, and prevent the dust from forming solid blocks during the accumulation process. This prevents the problem of poor material discharge caused by solid block blockage, and further ensures the smooth progress of material discharge.

[0010] 3. After the second motor starts, it drives the pusher block to move the movable plate back and forth through a series of transmission structures. The movable plate then pushes the swing plate closer to or away from the ash hopper through the connecting rod, so that the striking rod on the swing plate continuously strikes the side wall of the ash hopper. After the side wall of the ash hopper is subjected to continuous vibration, the dust and impurities originally attached to the side wall will fall smoothly to the bottom due to the vibration, avoiding the accumulation of dust on the inner wall of the ash hopper, ensuring that the dust in the ash hopper can be fully discharged, improving the integrity of the discharge, and ensuring the efficient operation of the subsequent conveying process.

[0021] Example: Figure 1-7As shown, this utility model provides a multi-tube dust collector ash hopper ash conveying device, including a multi-tube dust collector housing 1, an ash hopper 11 installed at the bottom of the multi-tube dust collector housing 1, a material sealing pump 5 connected to the bottom discharge port of the ash hopper 11, two symmetrically arranged baffles 2 movably inserted at the bottom of the ash hopper 11, connecting blocks 21 fixed at both ends of the baffles 2 outside the ash hopper 11, a protective cover 22 fixedly installed on the outer wall of the ash hopper 11 between the two connecting blocks 21, and a drive gear 23 rotatably installed at the middle end inside the protective cover 22, and diagonally arranged toothed plates 24 sliding inside the protective cover 22, with both toothed plates 24 meshing and connected to the drive gear 23, and the ends of the two toothed plates 24 away from the drive gear 23 fixedly installed on adjacent connecting blocks 21, and symmetrically arranged rotating rods 13 rotatably installed above the baffles 2 inside the ash hopper 11, with a spiral stirring component 14 fixedly installed on the rotating rods 13.

[0022] An electric push rod 25 is fixedly installed on the lower surface of the outer wall of the protective cover 22. The output end of the electric push rod 25 is fixedly installed on one of the connecting blocks 21. The electric push rod 25 mainly provides power for the movement of the toothed plate 24 and the baffle 2.

[0023] Two rotating rods 13 are connected at one end outside the ash hopper 11 by two meshing transmission gears 15. A first motor 16 is fixedly installed on the outer wall of the ash hopper 11. The output end of the first motor 16 is coaxially fixed on one of the rotating rods 13. The first motor 16, together with the two meshing transmission gears 15, can make the two rotating rods 13 rotate simultaneously, which is convenient for the staff to operate.

[0024] A connecting plate 3 in an inverted L-shape is fixedly installed on both sides of the outer wall of the ash hopper 11 adjacent to the first motor 16. A swing plate 31 is rotatably installed on the upper end of the connecting plate 3. Multiple equally spaced striking rods 32 are fixedly installed on the side of the swing plate 31 facing the ash hopper 11. A groove 33 is opened at the bottom of the connecting plate 3. A movable plate 34 is horizontally slidable in the groove 33. A connecting rod 35 is hinged together between the movable plate 34 and the swing plate 31. A movable groove 36 is opened at the middle end of the movable plate 34. A push block 37 is movably inserted in the movable groove 36. A horizontally arranged rotating plate 38 is fixedly installed on the upper end of the push block 37. A vertically arranged rotating shaft 39 is fixedly installed at the end of the rotating plate 38 away from the push block 37. The rotating shaft 39 is rotatably installed in the connecting plate 3. A second motor 4 is fixedly installed on the connecting plate 3. The output end of the second motor 4 is coaxially fixed on the rotating shaft 39. The second motor 4 mainly provides power for the rotation of the rotating shaft 39, which is convenient for the operator to operate.

[0025] The movable plate 34 has long plates 341 fixed at both ends and the long plates 341 are movably inserted into the grooves 33. The long plates 341 are mainly used to ensure that the movable plate 34 can be stably moved on the connecting plate 3.

[0026] Working principle: During use, when discharging the dust accumulated in the ash hopper 11, the electric push rod 25 is activated. When the output end of the electric push rod 25 extends, it drives the fixedly connected connecting block 21 to pull the toothed plate 24 gradually out of the protective cover 22. Since the two toothed plates 24 are meshed and connected on the drive gear 23, the other toothed plate 24 will also be driven and move away from the protective cover 22. Therefore, when the output end of the electric push rod 25 extends, it can push the two toothed plates 24 and the connecting block 21 to move away from the protective cover 22. This causes the connecting block 21 to pull the fixed baffle 2 to move in opposite directions, thus opening the baffle 2. The dust in the ash hopper 11 will be discharged normally to the bottom and enter the material sealing pump 5 for conveying. After the output end of the electric push rod 25 is retracted, the two baffles 2 will be subjected to force and move in opposite directions at the same time, thus causing the two baffles 2 to merge and intercept the bottom of the ash hopper 11. Through the above operation, the dust in the ash hopper 11 can be discharged intermittently, so that each discharge is within the conveying threshold of the material sealing pump 5, ensuring normal conveying.

[0027] At the same time, when the electric push rod 25 is working, the first motor 16 can be started at the same time. The first motor 16 will drive the two rotating rods 13 to rotate simultaneously through two meshing transmission gears 15. At this time, the spiral stirring component 14 fixed on the rotating rod 13 will rotate, so that the dust accumulated above the baffle 2 flows, and also avoids the formation of solid blocks during the accumulation process, which will prevent the material from being discharged normally.

[0028] When the second motor 4 is started, it drives the rotating shaft 39 to rotate. When the rotating shaft 39 rotates, it drives the rotating plate 38 and the push block 37 fixed at the bottom to rotate. At this time, the push block 37 pushes the movable plate 34 to move. The rotating plate 38 drives the push block 37 to move from one end of the movable groove 36 to the other end. Therefore, when the second motor 4 is working, it drives the push block 37 to push the movable plate 34 to move back and forth. At this time, the movable plate 34 pushes the swing plate 31 to move through the hinged connecting rod 35. Therefore, whenever the movable plate 34 pushes the swing plate 31 to move closer to the ash hopper 11, the knocking rod 32 fixed on the swing plate 31 will knock the ash hopper 11. After the above operation, the ash hopper 11 is continuously knocked, causing the side wall of the ash hopper 11 to vibrate. This allows the dust and impurities that are collected and attached to the side wall of the ash hopper 11 to fall smoothly to the bottom, avoiding accumulation and incomplete material discharge.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
