Description

Technical Field

[0001] This utility model relates to the field of ash silo maintenance equipment, and in particular to an ash silo clogging and unclogging device. Background Technology

[0002] Sintering machines are one of the important production equipment in the metallurgical industry. In steel production, sintering machines are used to sinter raw materials such as iron ore powder, coke powder, and limestone powder into sintered ore, and partially eliminate harmful impurities such as sulfur and phosphorus contained in the ore. The sintered products are the main raw materials for blast furnace ironmaking, which can improve the grade and metallurgical properties of iron ore and reduce the cost and energy consumption of blast furnace ironmaking.

[0003] A sintering machine mainly consists of a material feeding system, a combustion system, and a bellows system. The bellows system is connected to an exhaust fan via pipes. During the sintering process, the exhaust fan draws air from the sintering machine through the bellows, causing the mixture to burn and sinter under negative pressure. Since the sintering raw materials are mainly in powder form, non-combustible dust impurities are generated in the sintering machine. Therefore, multiple dust removal processes need to be incorporated into the bellows system. Consequently, in the metallurgical industry, sintering machines are typically equipped with dust collection hoppers to collect and temporarily store these dust impurities.

[0004] Dust silos often experience caking, with severe ash accumulation reaching the electrode plates. This not only prevents timely dust removal but also affects the normal operation of the electrostatic precipitator's electric field, resulting in poor dust removal efficiency. Currently, ash silos are cleaned primarily in two ways: First, cleaning personnel enter the silo for thorough cleaning, but this method is difficult and carries high safety risks, and is only suitable for periodic shutdown inspections, not for frequent manual cleaning. Second, during production, the silo's discharge port is opened, and holes are drilled in the exposed area to temporarily clear the caking, as described in CN210913761U's silo clearing device. This device uses a crankshaft reciprocating mechanism to move the drill bit back and forth to clear the discharge port. However, in this structure, the crankshaft's reciprocating stroke is limited, resulting in a shallow clearing depth. If a greater depth is needed, the drill rod needs to be lengthened and manually inserted into the caking, making the operation laborious. Summary of the Invention

[0005] This invention addresses the problem of the short stroke of current ash silo unblocking devices by providing an ash silo caking unblocking device with a longer stroke.

[0006] To solve the above problems, the technical solution adopted by this utility model is a device for clearing ash silo sludge buildup, including a drilling component. The drilling component includes a fixed base, on which a sliding base is provided. A drilling motor is mounted on the sliding base, and a drill bit is mounted on the output shaft of the drilling motor. It also includes a lifting component, which includes a winch connected to a steel wire rope. The steel wire rope is connected to the sliding base, and the steel wire rope can drive the sliding base to move upward along the fixed base. This device adopts a linear lifting structure. The sliding base carries the drilling motor and drill bit upward as a whole, driven by the winch, resulting in a larger stroke and the ability to clear deeper layers of ash silo sludge buildup. Simultaneously, when the sliding base is lowered to a low position, the overall height of the device is low, facilitating its placement below the ash silo outlet with minimal positional interference and ease of use.

[0007] As a preferred embodiment of a device for unclogging ash silos, the fixed base includes two guide rods arranged parallel to each other. The upper ends of the two guide rods are fixedly connected by an upper crossbar, and the lower ends of the two guide rods are fixedly connected by a lower crossbar. The sliding base includes two first guide sleeves, which are slidably fitted onto the two guide rods respectively. A mounting plate is provided between the two first guide sleeves, and the drilling motor is mounted on the mounting plate. The fixed base and the sliding base form a frame structure. Through the cooperation of the guide rods and guide sleeves, the stability and efficiency of drilling are improved, and the structure is simple, easy to manufacture and maintain.

[0008] As a preferred embodiment of a ash silo clogging and unclogging device, the winch has a winch base and is connected to the foundation structure via the winch base. A transverse support rod is provided between the winch base and the fixed base, with both ends of the transverse support rod connected to the winch base and the fixed base respectively. Both the winch base and the fixed base are set on the factory ground. The transverse support rod keeps the winch relatively far from the fixed base, reducing positional interference in the working area.

[0009] As a preferred embodiment of a device for clearing sludge buildup in ash silos, the lifting component further includes a pulley system disposed between the fixed base and the sliding base, with the wire rope wound around the pulley system. The pulley system reduces the load on the winch, extends its service life, and makes the lifting and lowering operation of the sliding base easier and smoother, thus improving the practicality and efficiency of the device.

[0010] As a preferred embodiment of a silo blockage clearing device, the pulley block includes at least one pair of fixed pulleys and a movable pulley. The fixed pulleys are mounted on the upper crossbar, and the movable pulleys are mounted on the mounting plate. A wire rope connecting seat is provided on the upper crossbar. The first end of the wire rope is connected to a winch, and the second end of the wire rope passes sequentially around the fixed and movable pulleys and is connected to the wire rope connecting seat. This effectively amplifies the pulling force of the winch, improves the lifting capacity of the device, ensures the stability and orderliness of the wire rope during lifting, reduces friction and wear of the wire rope, and makes the lifting of the sliding base more stable, which is beneficial to improving the quality and efficiency of borehole clearing.

[0011] As a preferred embodiment of a device for clearing sludge buildup in ash silos, a guide pulley is provided on the lower crossbar, and the wire rope located between the pulley block and the winch passes under the guide pulley. The plane of motion of the wire rope in the pulley block is located within the frame of the fixed base, and the wire rope is led out from the bottom of the fixed base to the winch through the guide pulley, thus avoiding interference with the sliding base.

[0012] As a preferred embodiment of a device for clearing sludge buildup in ash silos, an extension rod is mounted on the output shaft of the drilling motor, and the drill bit is mounted on the extension rod at the end furthest from the drilling motor. A second guide sleeve is also provided on the fixed base, through which the extension rod passes. The extension rod increases the distance between the drill bit and the drilling motor, allowing the drill bit to penetrate into narrower or deeper areas of sludge buildup within the ash silo for clearing operations, thus expanding the device's working range. Simultaneously, the second guide sleeve ensures the stability and accuracy of the drill bit's rotation, improving drilling quality and efficiency, and reducing the risk of the extension rod bending and being damaged due to drill bit wobbling.

[0013] As a preferred embodiment of the ash silo clogging unblocking device, the upper end of the fixed base is further provided with a fixed plate, and a through hole is opened on the fixed plate, through which the extension rod passes. This further improves the stability of the extension rod and drill bit during operation, ensuring smooth drilling operations.

[0014] As a preferred embodiment of the ash silo clogging and unblocking device, the fixed base is inclined relative to the horizontal plane, and the inclination angle is greater than 45°. This is more suitable for the inclined discharge port of the ash silo.

[0015] As a preferred embodiment of a device for clearing sludge buildup in ash silos, a handle is also fixedly installed on the sliding base. After drilling is completed, the winch reverses to loosen the wire rope. When the sliding base and drilling motor cannot descend under their own weight, the device can be manually reset using the handle.

[0016] As can be seen from the above technical solutions, the beneficial effects of this utility model are as follows: the ash silo caking unblocking device can open holes in the caking material inside the ash silo, ensuring the daily operation of the ash silo and normal ash discharge. The linear lifting structure has a larger stroke, which can unblock deep caking, and it is convenient to arrange and simple to operate when in a low position. The guide rods and sleeves of the fixed base and sliding base work together to improve drilling stability and efficiency, and are easy to process and maintain; the lateral support rods reduce positional interference between the winch and the fixed base in the working area; the pulley block and its combination of fixed and moving pulleys reduce the load on the winch, extend its service life, and enhance the lifting stability of the sliding base, improving the lifting capacity and drilling quality of the device; the guide pulleys prevent the wire rope from interfering with the sliding base; the extension rod, the second guide sleeve, and the fixed plate work together to expand the working range of the device and improve drilling stability and accuracy; the inclined design of the fixed base is adapted to the inclined discharge port of the ash hopper; the handle provides manual assistance when the device is difficult to reset, ensuring that the device can smoothly complete the work cycle, comprehensively improving the practicality, reliability, and work efficiency of the device; at the same time, when the equipment is shut down for maintenance, the ash hopper is cleaned from the surrounding area based on the opening, reducing labor intensity, speeding up the cleaning progress of the ash hopper, and reducing the safety risks of working in a confined space.

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] like Figure 1 As shown, a device for unclogging ash silos includes a drilling component. The drilling component includes a fixed base 8 adapted to the discharge angle of the ash silo. The fixed base 8 is inclined relative to the horizontal plane at an angle greater than 45°. A sliding base 7 is provided on the fixed base 8. Specifically, as shown... Figure 2 As shown, the fixed base 8 includes two guide rods 81, which are arranged parallel to each other. The upper ends of the two guide rods 81 are fixedly connected by an upper crossbar 82, and the lower ends of the two guide rods 81 are fixedly connected by a lower crossbar 83. The sliding base 7 includes two first guide sleeves 71, which are slidably fitted onto the two guide rods 81. An mounting plate 72 is provided between the two first guide sleeves 71. A drilling motor 3 is mounted on the mounting plate 72. An extension rod 2 is mounted on the output shaft of the drilling motor 3. A drill bit 1 is mounted on the end of the extension rod 2 away from the drilling motor 3. The fixed base 8 also has a second guide sleeve 13. Specifically, a connecting plate is provided between the two guide rods 81 at the upper part. The second guide sleeve 13 is mounted on the connecting plate, and the extension rod 2 passes through the second guide sleeve 13. The upper end of the fixed base 8 also has a fixed plate 14 with a through hole. The extension rod 2 passes through the through hole.

[0024] The drilling component is based on the fixed base 8 and consists of a frame formed by two parallel guide rods 81, an upper crossbar 82, and a lower crossbar 83. Two first guide sleeves 71 of the sliding base 7 are respectively fitted onto the guide rods 81, forming a slidable connection. A mounting plate 72 is fixed between the two guide sleeves. The drilling motor 3 is mounted on the mounting plate 72, and its output shaft is connected to the extension rod 2. The drill bit 1 is mounted at the end of the extension rod. The upper crossbar 82 of the fixed base 8 is equipped with a wire rope connecting seat 10, and the lower crossbar 83 is equipped with a guide pulley 9. A fixed plate 14 with a through hole is also provided at the upper end. The extension rod 2 passes through the through hole of the second guide sleeve 13 and the fixed plate 14 in sequence to ensure the stability of the drill bit 1 during operation. A handle 15 is also fixedly installed on the outside of the sliding base 7 for manual operation assistance.

[0025] The device also includes a lifting component, which serves as the power source for lifting the sliding base 7. The lifting component includes a winch 5, which has a winch base 51 and is connected to the foundation structure (i.e., the bottom of the factory building, the steel frame of the fixed ash silo, etc.) through the winch base 51. A transverse support rod 6 is provided between the winch base 51 and the fixed base 8. The two ends of the transverse support rod 6 are respectively connected to the winch base 51 and the fixed base 8. The winch 5 is connected to a wire rope 4, which is connected to the sliding base 7. The wire rope 4 can drive the sliding base 7 to move upward along the fixed base 8.

[0026] A pulley system is provided between the fixed base 8 and the sliding base 7. The wire rope 4 is wound around the pulley system. Specifically, the pulley system includes at least one pair of fixed pulleys 11 and movable pulleys 12. The fixed pulleys 11 are mounted on the upper crossbar 82, and the movable pulleys are mounted on the mounting plate 72. A wire rope connecting seat 10 is provided on the upper crossbar 82. The first end of the wire rope 4 is connected to the winch 5, and the second end of the wire rope 4 passes through the fixed pulleys 11 and the movable pulleys 12 in sequence and is connected to the wire rope connecting seat 10. A guide pulley 9 is also provided on the lower crossbar 83, and the wire rope 4 located between the pulley system and the winch 5 passes under the guide pulley 9.

[0027] The winch 5 of the lifting component is connected to the foundation structure via a winch base 51. A transverse support 6 is installed between the winch base 51 and the lower crossbar 83 of the fixed base 8 for reinforcement. One end of the wire rope 4 is connected to the winch 5, and the other end passes sequentially through the guide pulley 9, the fixed pulley 11, and the movable pulley 12 before being fixed to the wire rope connecting seat 10. The fixed pulley 11 is installed on the upper crossbar 82, and the movable pulley 12 is installed on the mounting plate 72 of the sliding base 7, forming a pulley block system. By winding and unwinding the wire rope 4, the winch 5 drives the sliding base 7 to rise linearly along the guide rod 81, realizing the drilling action of the drill bit 1. The wire rope 4 is led out from the bottom of the fixed base 8 via the guide pulley 9, so that the movement plane of the pulley block is located within the frame, further optimizing the spatial layout.

[0028] When the ash silo clogging unblocking device is in operation, the winch drives the sliding base to rise and fall along the guide rod on the inclined fixed base via a wire rope. Before starting, the device is positioned below the ash silo outlet, with the sliding base in a low position. At the start of operation, the winch winds up the wire rope, using the pulley system to pull the drilling motor and drill bit on the sliding base upwards until the drill bit reaches the clogging area in the ash silo. At this point, the drilling motor drives the extension rod and drill bit to rotate, drilling and breaking up the clogging material. The second guide sleeve and fixed plate ensure stable rotation of the drill bit. After unblocking, the winch reverses to release the wire rope. If the sliding base and drilling motor cannot descend under their own weight, they can be manually reset using the handle to return the device to its initial position, preparing for the next unblocking operation.

[0029] As can be seen from the above embodiments, the advantages of this utility model are: the ash silo caking unblocking device can open holes in the caking material inside the ash silo, ensuring the daily operation of the ash silo and normal ash discharge; the linear lifting structure has a larger stroke, can unblock deep caking, and is convenient to arrange and simple to operate when at a low position. The guide rods and sleeves of the fixed base and sliding base work together to improve drilling stability and efficiency, and are easy to process and maintain; the lateral support rods reduce positional interference between the winch and the fixed base in the working area; the pulley block and its combination of fixed and moving pulleys reduce the load on the winch, extend its service life, and enhance the lifting stability of the sliding base, improving the lifting capacity and drilling quality of the device; the guide pulleys prevent the wire rope from interfering with the sliding base; the extension rod, the second guide sleeve, and the fixed plate work together to expand the working range of the device and improve drilling stability and accuracy; the inclined design of the fixed base is adapted to the inclined discharge port of the ash hopper; the handle provides manual assistance when the device is difficult to reset, ensuring that the device can smoothly complete the work cycle, comprehensively improving the practicality, reliability, and work efficiency of the device; at the same time, when the equipment is shut down for maintenance, the ash hopper is cleaned from the surrounding area based on the opening, reducing labor intensity, speeding up the cleaning progress of the ash hopper, and reducing the safety risks of working in a confined space.
