Description

Technical Field

[0001] The present invention relates to the technical field of filter bag installation equipment, and more specifically, the present invention relates to a conveying mechanism for installing and fixing filter bags. Background Art

[0002] The filter bag is a key part during the operation of a bag-type dust collector. Usually, the cylindrical filter bag is vertically suspended in the dust collector. The fabric and design of the filter bag should strive for efficient filtration, easy dust stripping, and long durability. In pulse and plenum pulse dust collectors, the dust adheres to the outer surface of the filter bag. Among them, the cylindrical filter bag is widely used in bag dust collectors and is one of the most widely used filter bags in current dry dust removal. The filter bag consists of a spring snap ring and a filter bag. In order to ensure the filtration performance of the filter bag, the thickness of the filter bag is relatively thin.

[0003] When installing the existing filter bag, first place the simple protective cover of the filter bag into the hole of the flower plate, and then unfold and fold the filter bag to reduce its volume. The filter bag enters the interior of the dust collector through the simple protective cover. When the filter bag is sent into the interior of the dust collector, it should be slowly placed in accordance with the folding texture of the filter bag to ensure that the filter bag does not wrinkle, etc. When the top of the filter bag is about 200 - 500 millimeters away from the hole of the flower plate, extract the simple protective cover of the filter bag, and then open the elastic snap ring at the top of the filter bag and install it on the hole of the flower plate. The elastic snap ring must be fully expanded and closely fitted with the hole of the flower plate to complete the entire installation process. However, this installation method is not only not convenient enough, but in this process, although there is a protective cover, the length of the protective cover is short. When placing the filter bag at a deeper position, it tests the operation quality of the operator, thereby reducing the installation efficiency. Moreover, when installing a larger filter bag, due to the large elasticity of the spring snap ring, when the strength of a single hand of the operator is small, it is not convenient to snap the spring snap ring onto the flower plate opening, and the installation is not convenient enough.

[0004] Therefore, in view of this, the inventor, adhering to the rich design and development and actual production experience in this related industry for many years, studies and improves the existing structure and deficiencies, and provides a conveying mechanism for installing and fixing filter bags, in order to achieve better protection through the protective film, avoid the friction of the filter bag body in the hole of the flower plate, affect the service life of the filter bag body, improve the installation efficiency of the filter bag, avoid consuming a large amount of manpower to make it deform when the spring snap ring has a large elasticity, make the snap connection more firm, be adaptable to filter bags of different diameters, improve the adaptability range of the device, make the installation more flexible, and enable it to convey the installation of filter bags of different sizes.

The bottom of the elastic plate 32 is designed with a rough surface, which is convenient for fixing the locking bolt 52 to the bottom of the elastic plate 32 by rotating the support rod 53, so as to adjust according to the width of the filter bag.

[0032] Among them, the positioning rod 5 includes a socket ring 51. The socket ring 51 is movably sleeved on the outer surface of the elastic plate 32.

[0034] Working principle of the present invention: When in use, the fixed base 1 is placed inside the hole of the flower plate so that the fixed base 11 is located outside the hole of the flower plate. By starting the winding motor 46, the winding motors 46 at both ends are unwound synchronously, the winding shaft 47 rotates, and the winding rope 48 is stretched by the gravity of the positioning block 44. The protective film 43 is unfolded inside the hole of the flower plate. Subsequently, the spring clamp 6 is clamped on the outer surface of the support rod 53 at both ends. By starting the electric telescopic rod 224, the pushing block 225 is pushed toward the limiting rod 31 inside the moving groove 222. The elastic plate 32 is squeezed by the two ends of the limiting block 223, resulting in deformation and bending. At the same time, The middle part is squeezed by the push rod 227, so that the spring clamp 6 is deformed and fixed by the friction force of the outer surface of the support rod 53, thereby reducing the shape of the spring clamp 6. Subsequently, the filter bag body 7 is placed inside the protective film 43, and then the filter bag body 7 is placed inside the flower plate hole. Subsequently, the winding motor 46 is started to drive the winding shaft 47 to wind up, the positioning block 44 rises, and drives the protective film 43 to shrink to the bottom of the connecting ring 42, and the filter bag body 7 is quickly transported and arranged. The protection of the protective film 43 prevents the filter bag body 7 from rubbing in the flower plate hole, which affects the service life of the filter bag body 7 and improves the installation efficiency of the filter bag.

[0035] After the arrangement of the filter bag body 7 is completed, the lifting drive 14 is started to drive the rotating screw 15 to rotate, so that the lifting block 21 drives the adjusting assembly 22 and the spring snap ring 6 at the bottom to descend. When the spring snap ring 6 descends to the edge of the flower plate hole, the pulling block 228 is pulled out, and the push rod 227 is disengaged from the edge of the spring snap ring 6. The spring snap ring 6 recovers its deformation and is clamped to the edge of the flower plate hole, thereby fixing and installing the spring snap ring 6 and the filter bag body 7. Subsequently, the lifting drive 14 is started to drive the fixing assembly 2 to reset, and the spring snap ring 6 is clamped mechanically to avoid consuming a lot of manpower to deform the spring snap ring 6 when it is more elastic, and the clamping is more secure.

[0036] By providing the sleeve ring 51 and the support rod 53, when installing the filter bag on a smaller dust collector, the locking bolt 52 is rotated and disengaged from the bottom of the elastic plate 32 by rotating the support rod 53. According to the diameter of the filter bag or the hole in the flower plate, the distance of the support rod 53 is adjusted, and the support rod 53 is rotated in the opposite direction to fix the sleeve ring 51 to the bottom of the elastic plate 32, so that it can adapt to filter bags of different diameters, thereby improving the adaptability of the device and making the installation more flexible, so that it can be installed and transported for filter bags of different sizes.
