Description

Technical Field

[0001] The utility model patent belongs to the technical field of steel production, and in particular relates to a dust collector bag replacement device. Background Art

[0002] There are a large number of bag dust collectors in the construction of coking, sintering, pelletizing, ironmaking, steelmaking and other processes of steel enterprises. During the operation of the dust collector, the bag will age and be damaged and need to be replaced. Generally, the bag needs to be replaced every 2 years. However, in the actual working process, in addition to the bag and filter cartridge, the frequency of use of the dust collector, the on-site environment and temperature, the size of the flue gas dust and other factors will affect the dust removal effect of the bag dust collector. Therefore, the time to replace the bag and filter cartridge should refer to the theoretical data information and be determined according to the specific situation. In most cases, the bag needs to be replaced once a year, especially in high temperature, strong corrosion and high flue gas dust concentration environment, the bag replacement time will be shorter (3-8 months is possible). The damage of the bag can easily lead to excessive emissions, and the bag needs to be replaced in time to avoid environmental accidents. In some high-humidity environments, the bag is easy to stick to the bag, resulting in excessive pressure difference in the operation of the dust collector, which brings safety and environmental risks, and the bag also needs to be replaced in time. Since many dust collectors need to replace bags that are filled with dust, it is very laborious to pull out the bags. Only a few bags can be pulled out every day by manpower. Manual replacement can also easily cause the bags to fall into the dust collector, clogging the ash hopper unloading valve, etc., affecting the normal operation of the dust collector.

[0003] Therefore, it is necessary to improve the bag replacement technology of the existing bag dust collector to improve the replacement efficiency, reduce manual intervention, ensure the stable operation of the bag dust collector, and meet the requirements of environmental protection and safe production.

[0030] The dust collector bag replacement device is carefully designed, and each structural feature has its own unique advantages, which together improve the efficiency and safety of bag replacement. The following is a detailed analysis of each structural feature:

[0031] Leg assembly:

[0032] Three-leg assembly: The three-leg assembly design ensures the stability of the device during operation, especially when handling heavy bags. The three legs can evenly share the weight to prevent the device from tilting or collapsing.

[0033] Upper sliding sleeve: The upper sliding sleeve is hinged to the upper part of the leg assembly, allowing the lifting beam to move up and down within a certain range to meet the needs of bag replacement at different heights.

[0034] Lower legs and upper legs: Through the plug-in design, the length of the legs can be adjusted as needed to adapt to dust collectors of different heights.

[0035] Outrigger base: The horizontally arranged outrigger base increases the contact area between the device and the ground, further improving stability.

[0036] Locking screw: The locking screw on the lower leg can fix the position after adjusting the leg length to prevent the leg length from changing during use.

[0037] Rotation axis and lifting beam:

[0038] Rotating axis: The design of the rotating axis allows the lifting beam to rotate within a certain range, which enables the device to adapt to the needs of bag replacement at different angles.

[0039] Lifting beam: As the load-bearing component of the entire lifting assembly, the lifting beam is made of strong and durable materials and can withstand heavy weight.

[0040] Lifting assembly:

[0041] Winch Sliding Sleeve: The design of the sliding sleeve allows the winch to move on the lifting beam so that the bag can be accurately positioned. The locking screw is used to fix the position of the winch.

[0042] Winch: The winch is the core component of the device. With its strong pulling force, the bag can be quickly pulled out. The use of 24V motor ensures safety and avoids electric shock accidents.

[0043] Wire rope and hook: The wire rope has high strength and durability and can bear the weight of the bag. The two hooks run alternately up and down, which significantly increases the speed of pulling out the bag.

[0044] The technical solution of the utility model has the following advantages:

[0045] High efficiency: The electric winch is used as the power source, replacing the traditional manual extraction method, which significantly improves the speed of bag replacement. It is estimated that the use of an electric winch can increase work efficiency by about 50 times.

[0046] Safety: The electric winch adopts 24V safe voltage, which avoids the risk of electric shock accidents and improves the safety of operation.

[0047] Flexibility: The overall design of the device is a special tool for replacing bags. The winch is detachable and movable, so it can be quickly transferred and used between different bag dust collectors.

[0048] Stability: Through the design of the leg assembly, the device can be stably installed on the top of the bag dust collector at different heights and angles. The leg assembly includes a lower leg and an upper leg, which are connected by plug-in and hinged methods, can be telescopically adjusted, and are convenient for installation and fixation. A bracket base plate is provided at the bottom of the leg, which is connected to the fixing bolts of the top chamber cover of the bag dust collector by bolts, further improving the stability of the device.

[0049] Convenience: The lifting beam is connected to the overall device through a rotating shaft and can rotate 360 ​​degrees, which is convenient for all-round bag replacement operations. This greatly simplifies the operation process and improves work efficiency.

[0050] Avoid human errors: By using special hooks to hook the bag cage and bag, errors in manual operation can be effectively avoided, such as bags falling into the dust collector, blocking the ash hopper unloading valve, etc., thereby reducing dust collector operation accidents caused by human factors.

[0051] Working principle:

[0052] When the bag filter needs to replace the bag, first move the device to the top of the dust collector chamber. Then close the chamber that needs to be replaced and open the cover on the top of the chamber. Next, fix the installation part of the device to the preset fixing bolts and connect the maintenance power supply. Then, use the hook on the device to hook the bag cage and bag that need to be replaced. Start the electric winch, and use the winch and wire rope on the winch to raise the hook and bag together. Since the device is designed with two hooks, and these two hooks can run alternately up and down, the speed of pulling out the bag can be significantly increased. When the bag is pulled out to a certain height, the operator can manually remove the bag and replace it with a new bag. The whole operation process is simple and easy, and the efficiency is extremely high.

[0053] In summary, the dust collector bag replacement device achieves efficient, safe and convenient bag replacement by adopting designs such as electric winch, adjustable legs and rotating lifting beam. This not only improves work efficiency and reduces labor intensity, but also reduces potential risks caused by human errors.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
