Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of disassembly tools, and particularly relates to a special tool for pulling out the dust removal bag of a dust collector. Background Technique
[0002] A bag filter is a common industrial dust removal device that captures particulate matter through a bag filter medium. After the flue gas enters the dust collector, the particulate matter deposits on the bags, and the filtered clean gas is discharged through the outlet. According to the different filtration areas, the dust collector will have hundreds to thousands of bags arranged in an array, and the operation of removing and replacing the bags is essential. Due to reasons such as long-term thermal expansion, orifice plate corrosion, and dust accumulation and caking during the use of the bags, the bags are bonded to the orifice plate. During the removal operation, two workers need to cooperate. One uses a flat screwdriver and the other uses a crowbar to pry up and fold inward the elastic ring clamped into the orifice plate at the bag mouth, and at the same time apply force to lift upwards to disengage the elastic ring at the bag mouth from the orifice plate. This operation is time-consuming and laborious, and the efficiency is low. Summary of the Invention
[0003] In view of the above problems in the prior art, the utility model provides a special tool for pulling out the dust removal bag of a dust collector. The technical solution is as follows: at least one internal thread is provided on the cross beam, the internal thread is threadedly connected with the screw rod, a pin hole is opened at the bottom of the screw rod, the screw rod is hinged to the rotating lifting ring through a pin, a traction rope is passed through the rotating lifting ring, and hooks are provided at both ends of the traction rope.
[0004] As a preferred solution, the lower part of the cross beam is fixedly connected with a guide pipe, and the guide pipe wraps the screw rod.
[0005] As a preferred solution, the end wall of the guide pipe is rounded.
[0006] As a preferred solution, the lower part of the cross beam is fixedly connected with a bracket, and the cross beam and the bracket form a portal frame structure.
[0007] Advantages of the Utility Model
[0008] (1) By rotating the screw rod, the screw rod drives the traction rope on the rotating lifting ring, and the hooks of the traction rope can easily and quickly pull out the bag at one time, improving the pulling efficiency of the bag and reducing the labor intensity of manual work;
[0009] (2) Multiple sets of screw rods can be provided in the device to pull multiple bags, further improving the working efficiency;
[0010] (3) The rounding treatment of the guide pipe prevents damage to the bag and reduces the damage rate of the bag. Description of the Drawings

[0015] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0016] Embodiment
[0017] As Figure 1-2 Shown is a special tool for pulling out the dust collector bag. Five internal threads 4 are provided on the cross beam 1. The internal thread 4 is threadedly connected with the screw 3. The bottom of the screw 3 is provided with a pin hole. The screw 3 is hinged to the rotating sling 6 through a pin. A towing rope 7 is threaded through the rotating sling 6. Hooks 8 are provided at both ends of the towing rope 7.
[0018] Further, the lower part of the cross beam 1 is fixedly connected with the guide tube 5. The guide tube 5 wraps the screw 3. The guide tube 5 is used to limit the rising direction of the bag and prevent the bag from shaking and increasing the labor intensity of the operator.
[0019] Further, the end wall of the guide tube 5 is rounded. The rounding treatment makes the guide tube 5 more rounded and prevents the bag from being scratched during the pulling process, reducing the damage rate of the bag.
[0020] Further, the lower part of the cross beam 1 is fixedly connected with the bracket 2. The cross beam 1 and the bracket 2 form a portal frame structure. The bracket 2 is used to support the cross beam 1. If the bag is too heavy, pads can be added to the lower end of the cross beam 1 on the basis of the existing bracket 2.
[0021] Using the above tool, its use process and principle are as follows:
[0022] The tool is placed on the bag hole plate along the arrangement direction of the bags, and the hook 8 is hooked between the two elastic rings, symmetrically hooked into and pierced through the bags, and then the electric wrench is used to drive the rotating screw 3 to drive the traction rope 7 and the hook 8 to rise. Under the influence of the oblique lifting force F1, the upper elastic ring begins to shrink and deform, and the screw 3 is continued to rotate, and the traction rope 7 rises. Under the constraint of the guide tube 5, the traction rope 7 and the hook 8 simultaneously generate axial centripetal force F2 and radial lifting force F at the bag mouth. F2 continues to shrink the bag mouth, causing the lower elastic ring to deform inward and separate from the hole plate. Under the action of the radial lifting force F, the bag is pulled out of the hole plate. At this time, the electric wrench is rotated and reversed, and the rotating screw is rotated downward. After loosening the wire rope, the hook is taken out, and the above operation is repeated to pull out all the remaining bags. In actual operation, if the bag is too tightly attached to the hole plate, and the tension value is too large to cause the beam 1 to wrap down, a wooden block can be added under any beam position between the two brackets 2 to increase the support force of the beam 1.
