[0002] The ground dust removal station of the coking plant is a device used to treat dust and pollutants generated during the production process of the coking plant. In the process of producing coke in the coking plant, a large amount of dust and exhaust gas will be generated. The filter bags inside the ground dust removal station will capture and filter the solid particles in the dust and exhaust gas. After a long period of operation, the filter bags will accumulate a large amount of particulate matter, resulting in a decrease in filtration efficiency. At this time, the filter bags need to be replaced to ensure the efficient operation of the dust removal system.

[0003] When replacing the filter bag in the existing ground dust removal station, the filter bag frame needs to be pulled out. When pulling it out, the operator often uses a crowbar or a hook to do the operation. These tools can only apply force to one force point of the filter bag frame, resulting in uneven force on the filter bag frame. This uneven force will damage the filter bag frame, thereby increasing the replacement cost. Utility Model Content

DETAILED DESCRIPTION

[0023] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] See also Figure 1-4 As shown, the utility model provides a filter bag skeleton extraction tool for replacing filter bags in a ground dust removal station, comprising four groups of cross-distributed fixing frames 1, outer rods 3 and hook heads 5 for hooking the filter bag skeletons, the four groups of fixing frames 1 are fixed by a central disk 11, the outer sides of the four groups of fixing frames 1 are slidably connected with slip rings 2, the outer rods 3 are detachably connected below the slip rings 2, the inner lower ends of the outer rods 3 are slidably connected with inner rods 4, the hook heads 5 are detachably connected below the inner rods 4, an adjusting component 6 for adjusting the movement of the slip ring 2 is connected to the central disk 11, and the outer sides of the four groups of fixing frames 1 are fixedly connected with limit rings 8 for limiting the movement of the slip ring 2.

[0025] The utility model arranges a slip ring 2, and the outer sides of the four groups of fixed frames are slidably connected with a group of slip rings, each group of slip rings 2 corresponds to a hook head 5, and the four groups of hook heads 5 are distributed in a cross shape, so that when the filter bag skeleton is extracted, the four groups of hook heads 5 act on the filter bag skeleton at the same time, thereby providing a more uniform force and reducing the breakage rate of the filter bag skeleton during the replacement process.

[0026] When extracting the filter bag skeleton, by applying an upward force to the fixing frame 1, the filter bag skeleton can be indirectly driven to move upward through the slip ring 2, the outer rod 3, the inner rod 4 and the hook head 5, so that the filter bag skeleton can be extracted, and the operation is simple and convenient. Since the four groups of fixing frames 1 distributed in a cross form provide four points of action, when the filter bag skeleton is difficult to extract, it can support multiple operators to operate at the same time, thereby increasing the extraction force and ensuring that the filter bag skeleton is smoothly extracted.

[0027] The function of the limit ring 8 is that when the slip ring 2 slides to one side of the limit ring 8, it will be blocked by the limit ring 8 and cannot move further. At this time, the limit ring 8 plays a limiting role, thereby preventing the operator from excessively moving when adjusting the position of the slip ring 2. In addition, when extracting the filter bag skeleton, the limit ring 8 can be pre-positioned according to the inner diameter of the filter bag skeleton in advance, so that when adjusting the position of the slip ring 2, there is no need to repeat the positioning. The position of the hook head 5 can be determined by sliding the slip ring 2 to one side of the limit ring 8. At this time, the limit ring 8 plays a positioning role.

[0028] Furthermore, the lower surface of the slip ring 2 is fixedly connected with a connecting sleeve 21, and the upper surface of the outer rod 3 is fixedly connected with a fixing rod 31, and the fixing rod 31 is threadedly connected to the inside of the connecting sleeve 21; the outer rod 3 is threadedly connected to the inside of the connecting sleeve 21 through the fixing rod 31, so as to realize a detachable structure. When not in use, the outer rod 3 can be removed to save storage space.

[0029] Furthermore, two groups of through holes 32 are formed on the outer wall of the outer rod 3, and a threaded hole 41 is formed on the outer wall of the inner rod 4. The interiors of the two groups of through holes 32 are movably connected with fixing bolts 42. The ends of the fixing bolts 42 pass through the through holes 32 and extend to the interiors of the threaded holes 41. The fixing bolts 42 are threadedly connected to the threaded holes 41. The outer rod 3 and the inner rod 4 are fixed by the fixing bolts 42. During use, the overall lengths of the outer rod 3 and the inner rod 4 can be adjusted in real time according to the installation depth of the filter bag skeleton, so that the tool can be suitable for extracting filter bag skeletons of different depths, providing greater flexibility and applicability.

[0030] Furthermore, the outer wall of the inner rod 4 is provided with a plurality of groups of marking lines 43 for determining the position of the outer rod 3; when fixing the outer rod 3 and the inner rod 4, it is necessary to ensure that the threaded hole 41 and the through hole 32 are in the same position, and the role of the marking lines 43 is that when the threaded hole 41 and the through hole 32 are in the same position, the lower surface of the outer rod 3 is just flush with the marking lines 43. Since the position of the marking lines 43 is directly related to the position of the outer rod 3, the operator can visually determine the position of the outer rod 3 by observing the position of the marking lines 43. With the reference of the marking lines 43, the operator does not need to determine the position of the outer rod 3 through other complicated measurements or trial and error, thereby saving positioning time. This intuitive positioning method can quickly and accurately complete the adjustment of the tool and improve work efficiency.

[0031] Furthermore, a threaded rod 51 is fixedly connected to the upper surface of the hook head 5, and the threaded rod 51 is threadedly connected to the inner bottom of the inner rod 4; the hook head 5 is fixed to the inner rod 4 by a threaded connection, which is convenient for subsequent maintenance and replacement.

[0032] Furthermore, a rubber pad is provided on the outer side of the hook head 5; the provision of the rubber pad increases the friction between the hook head 5 and the filter bag frame, so that when the filter bag frame is hooked, the hook head 5 is more easily and firmly fixed on the frame, reducing the possibility of accidental falling off and improving work efficiency. Secondly, the contact between the filter bag frame and the hook head 5 will cause wear, and the rubber pad can serve as a buffer layer to reduce the direct contact between the hook head 5 and the filter bag frame, thereby reducing wear and extending the service life of the hook head 5.

[0033] Further, the adjustment assembly 6 includes an adjustment rod 61, which is rotatably connected to the upper surface of the center disk 11, a knob 611 is fixedly connected to the upper surface of the adjustment rod 61, a sliding seat 62 is provided on the outer thread sleeve of the adjustment rod 61, and a connecting buckle 1 63 is fixedly connected to the sliding seat 62 on all sides, a connecting rod 64 is rotatably connected to the inner side of the connecting buckle 1 63, and a connecting buckle 2 65 is rotatably connected to the end of the connecting rod 64 away from the connecting buckle 1 63, and the connecting buckle 2 65 is fixedly connected to the upper surface of the slip ring 2; by rotating the knob 611, the knob 611 drives the adjustment rod 61 to rotate, and at this time, the sliding seat 62 can move vertically along the axis of the adjustment rod 61, and the slip ring 2 can be driven to slide on the outer side of the fixed frame 1 through the mutual cooperation between the connecting buckle 1 63, the connecting rod 64 and the connecting buckle 2 65. Only one set of adjustment rods 61 needs to be rotated to drive four sets of slip rings 2 to move synchronously, and the operation is simple and convenient.

[0034] Furthermore, the four sets of fixing frames 1 are fixedly connected to the side away from the center plate 11 with a connecting seat 12, and the side of the connecting seat 12 is fixedly connected to a handle 7, and the outer side of the handle 7 is provided with a soft pad 71; when the operator extracts the filter bag skeleton, he can extract it by holding the handle 7, and the handle 7 provides a convenient gripping point, so that the operator can easily extract the filter bag skeleton. The setting of the soft pad 71 provides additional comfort and grip. During long-term operation, the soft pad 71 can reduce the pressure on the hand and reduce the discomfort caused by continuous pressure, making the operator more comfortable.

[0035] Working principle: Step 1: adjust the position of the limit ring 8 outside the fixing frame 1 according to the inner diameter of the filter bag frame to be replaced. Step 2: adjust the length of the inner rod 4 extending out of the outer rod 3 according to the installation depth of the filter bag frame, and fix it with the fixing bolt 42 to ensure that the operator can easily operate the inner rod 4 on the ground dust removal station. Step 3: insert the four sets of hook heads 5 into the filter bag frame. After inserting to a certain depth, manually rotate the knob 611, and the knob 611 drives the adjustment rod 61 to rotate. At this time, the sliding seat 62 moves downward. Through the mutual cooperation of the connecting buckle 1 63, the connecting rod 64 and the connecting buckle 2 65, the sliding ring 2 can be driven to slide on the outside of the fixing frame 1, thereby indirectly driving the four sets of hook heads 5 to approach the filter bag frame. When the sliding ring 2 is fitted with the limit ring 8, the knob 611 can be stopped from rotating. At this time, the position of the hook head 5 is just at the filter mesh frame. Step 4: The operator pulls the fixing frame 1 upward through the handle 7, thereby indirectly driving the filter bag frame to move upward, and realizing the extraction of the filter bag frame.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
