Description

Technical Field

[0001] This utility model relates to the field of industrial dust removal equipment, and in particular to a pulse bag dust collector for lime silos. Background Technology

[0002] In the industrial production field, lime silos generate a large amount of dust during material storage and processing, which seriously affects the working environment and personnel health. Therefore, pulse bag dust collectors have become the key equipment in lime silo dust removal systems. Currently, pulse bag dust collectors for lime silos, which are widely used in the market, have revealed many problems that urgently need to be solved in actual use.

[0003] Traditional pulse jet baghouse dust collectors have design flaws in the maintenance or replacement of filter bags. Due to the compact internal space and complex structure of the dust collector, operators often need to overcome the limitations of the confined space to enter the dust collector in order to complete the maintenance and replacement of the filter bags. This operation method not only greatly increases the difficulty and labor intensity of the operators, but also poses a high safety risk. In addition, the confined operating space also makes the replacement of filter bags inefficient, consuming a lot of time and labor costs.

[0004] In addition, when dust collectors need to be moved due to production layout adjustments or other reasons, they usually need to be disassembled, then moved with the help of forklifts, cranes and other handling equipment, and then reassembled in the new installation location. This process is cumbersome and requires a lot of manpower and resources. Moreover, the disassembly and reassembly process can easily damage equipment parts, increase equipment maintenance costs, and also lead to a long period of production interruption, which seriously affects production efficiency.

[0005] Therefore, it is necessary to provide a new pulse bag dust collector for lime silos to solve the above-mentioned technical problems. Utility Model Content

A dust hopper is installed at the bottom of the outer shell, and the dust collector body is installed inside. A movable base is installed at the bottom of the dust hopper. A lifting assembly is installed between the movable base and the outer shell. The lifting assembly drives the outer shell to rise and fall to lower the center of gravity during movement. A fixed frame for fixing the dust collector body is slidably installed inside the outer shell. A drive assembly is installed between the outer shell and the fixed frame. The drive assembly drives the fixed frame to move and push the dust collector body out of the outer shell. A hatch is installed on the side wall of the outer shell.

[0015] Compared with related technologies, the pulse bag dust collector for lime silos provided by this utility model has the following beneficial effects:

[0016] The design of the drive components and the hatch eliminates the need to enter the equipment to maintain the dust collector bags. This design significantly reduces the difficulty of maintenance operations, making maintenance tasks such as replacing dust collector bags more convenient, effectively improving maintenance efficiency, reducing equipment downtime caused by maintenance, and ensuring the continuity of lime silo production.

[0017] Through the design of the lifting components and omnidirectional wheels, when the equipment needs to be moved, the operator only needs to disassemble the top pipe and activate the electric actuator to retract, so that the outer shell and dust collector body can be lowered smoothly, effectively lowering the center of gravity of the equipment and enhancing the stability of movement. The entire movement process does not require complicated disassembly and assembly steps, which greatly saves manpower and material resources, shortens the time required for equipment movement, avoids damage to parts that may be caused by disassembly and assembly, reduces equipment maintenance costs, and at the same time reduces production interruption time and improves enterprise production efficiency.

[0018] By extending the dust collector body out of the outer casing for maintenance, operators do not need to enter the equipment, avoiding the risks associated with space constraints. Furthermore, during equipment movement, the lower center of gravity and the use of casters reduce the possibility of tipping over, collisions, or other accidents, ensuring the personal safety of operators during equipment movement and creating a safer production environment for the company.

[0031] The working principle of the pulse bag dust collector for lime silos provided by this utility model is as follows:

[0032] I. Working Principle of Dust Collector Body Maintenance

[0033] When the dust collector body 3 needs maintenance, the operator starts the electric push rod 10; the output end of the electric push rod 10 begins to extend, driving the push plate 11 fixedly connected to it to move horizontally inside the outer shell 1; since the push plate 11 is fixedly connected to the fixed frame 5, the fixed frame 5 and the dust collector body 3 installed therein will move together towards the outer wall of the outer shell 1 under the push of the push plate 11.

[0034] During the movement of the push plate 11, the rack 13, which is symmetrically fixed in the middle of the push plate 11, moves synchronously. The rack 13 meshes with the driving gear 14. According to the gear transmission principle, the linear motion of the rack 13 is converted into the circular rotation of the driving gear 14. The variable speed gear 15, which is fixed at the shaft of the driving gear 14, rotates synchronously with the driving gear 14. Since the outer diameter of the variable speed gear 15 is larger than that of the driving gear 14 and the driven gear 16, this size difference allows the variable speed gear 15 to drive the driven gear 16, which it meshes with, to rotate at a faster speed. After the driven gear 16 rotates, it drives the rack 17, which is meshed with it at the bottom, to slide outward along the inner wall of the outer shell 1 through the meshing relationship between the gear and the rack.

[0035] During this series of transmission processes, due to the speed-increasing effect of the transmission gear 15, the rack 2 17 will first contact the hatch 6 installed on the side wall of the outer shell 1 and apply a thrust to the hatch 6, pushing the hatch 6 to rotate around its rotation axis and open; during the process of the hatch 6 rotating and opening, the slide rod 20 rotatably connected at both ends of the hatch 6 is subjected to tensile force, slides inside the sleeve 18 and stretches the tension spring 19 inside the sleeve 18; when the tension spring 19 is stretched, it stores elastic potential energy, providing power for the hatch 6 to return to its original position;

[0036] As the electric actuator 10 continues to operate, the push plate 11 continues to move. When the top rod 12 fixed at the bottom of the push plate 11 contacts the bottom of the door 6, the rack 17, after completing the task of pushing the door 6 to open initially, gradually disengages from the door 6. The top rod 12, with the thrust of the electric actuator 10, continues to apply force to the door 6, ensuring that the door 6 is fully opened, providing sufficient space for the smooth ejection of the fixing frame 5 and the dust collector body 3. After the fixing frame 5 and the dust collector body 3 inside are completely ejected from the outer shell 1, the operator closes the electric actuator 10. At this time, convenient maintenance operations can be performed on the dust collector body 3, such as replacing the dust collector bag and inspecting internal parts.

[0037] After maintenance is completed, the electric actuator 10 is restarted to retract; the output end of the electric actuator 10 drives the push plate 11 to move in the opposite direction, thereby pulling the fixed frame 5 and the dust collector body 3 to reset; during the reverse movement of the top rod 12, the elastic potential energy stored in the tension spring 19 is released, pulling the slide rod 20 to drive the door 6 to gradually rotate in the opposite direction; at the same time, the rack 13 moves in the opposite direction, driving the drive gear 14, the speed change gear 15 and the driven gear 16 to rotate in the opposite direction, so that the rack 17 also moves in the opposite direction. Finally, the door 6 is reset and tightly fits the outer shell 1, resealing the outer shell 1 and ensuring the normal operation environment of the dust collector;

[0038] II. Working Principle of Equipment Movement

[0039] When the pulse bag filter needs to be moved due to production layout adjustments or other reasons, the operator should first disassemble the pipes connected to the top of the outer casing 1 for conveying dust and gas to avoid damaging the pipes or affecting the movement of the equipment during the move.

[0040] Next, the electric actuator 7 is activated to retract. The output end of the electric actuator 7 is fixedly connected to the top of the movable base 4. During the retraction of the electric actuator 7, the pulling force generated by its output end acts on the movable base 4. At this time, the guide frame 8 fixedly connected to the bottom outer wall of the outer shell 1 and the guide rod 9 fixed at the top diagonally of the movable base 4 cooperate with each other. The guide rod 9 slides in the limiting hole of the guide frame 8, providing a stable guiding effect for the lifting and lowering of the outer shell 1, and preventing the outer shell 1 from deviating or shaking during the lifting and lowering process. Under the tension of the electric actuator 7 and the constraint of the guide assembly, the outer shell 1 and the dust collector body 3 inside descend smoothly in the vertical direction. As the outer shell 1 descends, the center of gravity of the entire equipment also decreases, which enhances the stability of the equipment during the movement and reduces the risk of tipping over.

[0041] When the outer casing 1 descends to be completely in contact with the movable base 4, the operator closes the electric push rod 7. At this time, the equipment is in a stable state with a low center of gravity. Then, the self-locking casters installed at the bottom of the movable base 4 are unlocked. The casters can rotate freely, allowing the operator to easily push the equipment on the ground and move the equipment to the target position.

[0042] After the equipment reaches the target position, the operator locks the casters to prevent the equipment from slipping during subsequent use; then, the electric actuator 7 is activated to extend it, and the output end of the electric actuator 7 pushes the outer shell 1 and the internal dust collector body 3 to rise; under the guidance of the guide rod 9 and the guide frame 8, the outer shell 1 rises smoothly to the initial height; finally, the previously disassembled pipes are reconnected, and the equipment can be put into normal use in the new position, completing the entire relocation process.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
