Description

Technical Field

[0001] This invention relates to the field of dust collectors, specifically to a dust collector bag cage frame for a bag filter that is easy to assemble and disassemble. Background Technology

[0002] A bag filter is a dry dust filtration device. It is suitable for collecting fine, dry, non-fibrous dust.

[0003] In existing technologies, baghouse dust collectors are equipped with multiple filter bags inside. The filter bags are made of woven filter cloth or non-woven felt. They use the filtration effect of fibrous fabric to filter dust-laden gas. When dust-laden gas enters the baghouse dust collector, large and heavy dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust particles passes through the filter media, the dust is trapped, thus purifying the gas. Typically, the filter bags are fitted onto a frame, and then the frame is installed inside the baghouse dust collector.

[0004] However, the frame is usually suspended at the top inside the bag filter, so workers cannot quickly load or unload the frame from the bottom. Summary of the Invention

The clamping block 5 is slidably connected within the mounting groove 4. The bottom surface of the clamping block 5 is provided with an inclined surface 13. The notch 6 is a square groove, located on the top surface of the clamping block 5. The stop bar 7 is located within the notch 6, and its two ends are respectively fixed to two parallel sidewalls of the mounting groove 4. A rubber gasket 8 is fixed to the surface of the clamping block 5. A space is provided between the notch 6 and the stop bar 7. The device includes an elastic traction component, comprising a rubber clamp 9, a pre-reserved opening 10, an elastic plastic support ring 11, and a rubber connecting plate 12. The rubber clamp 9 is fixed between the stop bar 7 and the notch 6. The pre-reserved opening 10 is elliptical and is located on the surface of the rubber clamp 9. The elastic plastic support ring 11 is an elliptical ring plate structure and is fixed in the pre-reserved opening 10.

[0032] Example 3

[0033] See attached document Figure 3 Based on Embodiment 2, in order to push the clamping block 5 to fix the upper end plate 1 onto the internal mounting frame of the bag filter, the regulating traction component includes a pushing ring 15, a traction rod 18, a through hole 19, and a traction ring 20. The pushing ring 15 is sleeved on the outside of the upper end plate 1. Multiple traction rods 18 are provided, and one end of each traction rod 18 is fixed to the bottom surface of the pushing ring 15. The traction rod 18 passes through the through hole 19, which is opened on the surface of the hoop 3. The other end of the traction rod 18 is fixed to the top surface of the traction ring 20. The traction ring 20 is sleeved on the outside of the lower end plate 21. The upper end plate 1... A rubber ring 22 is fixed to the inner ring surface of the upper end plate 1. The rubber ring 22 is located below the mounting groove 4. The limiting stop includes a washer 14, a rubber clamp strip 16, and a baffle 17. The washer 14 has an annular plate structure. The inner ring of the washer 14 is fitted and fixed to the outer wall of the upper end plate 1. The rubber clamp strip 16 is a semi-cylindrical strip. There are multiple rubber clamp strips 16. The multiple rubber clamp strips 16 are arranged along the outer ring surface of the upper end plate 1. The baffle 17 has an arc-shaped plate structure. There are multiple baffles 17. The baffles 17 and the mounting groove 4 are distributed alternately. The inner ring surface of the baffle 17 is fixed to the outer wall of the upper end plate 1.

[0034] In actual use, the lower end plate 21 is held in place to support the frame, and the upper end plate 1 is placed on the mounting frame inside the bag filter. At this time, the rubber ring 22 is clamped between the mounting frame and the upper end plate 1 to achieve an anti-slip effect. The upward traction ring 20 slides along the lower end plate 21. When the traction ring 20 drives the traction rod 18 to rise, the traction rod 18 pushes the pushing ring 15 to rise. The pushing ring 15 squeezes the clamping block 5 along the inclined surface 13 until the rubber gasket 8 is clamped between the clamping block 5 and the mounting frame. During this process, when the clamping block 5 moves, it squeezes the rubber clamping block 9 and the elastic plastic support ring 1. 1. Elastic deformation: At this time, the rubber clamping strip 16 is clamped between the pushing ring 15 and the upper end plate 1, which plays a damping role and prevents the pushing ring 15 from falling randomly. At this time, the pushing ring 15 blocks the clamping block 5 to prevent the clamping block 5 from moving backward. In this way, the upper end plate 1 can be quickly installed on the mounting frame. Pull the traction ring 20 down, and the pushing ring 15 will slide down through the traction rod 18. When the pushing ring 15 no longer blocks the clamping block 5, the rubber clamping block 9 and the elastic plastic support ring 11 rebound, and the clamping block 5 no longer clamps the mounting frame. The frame can then be removed from the mounting frame.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
