Description

Technical Field

[0001] This utility model relates to the technical field of installation and disassembly of screen cages for slag water filters, and in particular to a device for installing and disassembling screen cages for slag water filters. Background Technology

[0002] During operation, slag water filters often develop hardened slabs on the inner wall of the filter housing, requiring disassembly of the screen cage and subsequent cleaning of the housing. Disassembly is also necessary when the screen cage is severely worn. Currently, disassembling the screen cage involves welding three lifting lugs spaced 120 degrees apart to the inner wall of the cage, then using a hand-operated hoist to pull it out. This method is time-consuming and labor-intensive, severely impacting the efficiency of disassembly and installation. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0019] Embodiment 1 of this utility model

[0020] Reference Figures 1-4A device for installing and disassembling a slag filter screen cage includes a disassembly housing 3 and a slide rail 4, with the disassembly housing 3 slidably connected to the slide rail 4. A rotating plate 5 is rotatably connected inside the slag filter housing 1, and the screen cage 2 is detachably connected to the rotating plate 5. A first threaded hole 21 is formed in the bottom plate of the screen cage 2, and a second threaded hole 51 is formed on the rotating plate 5. A first bolt 22 is provided on the screen cage 2, and the first bolt 22 is threadedly connected to the second threaded hole 51 through the first threaded hole 21, thereby fixing the bottom plate of the screen cage 2 to the rotating plate 5.

[0021] A central hole 23 is provided at the center of the bottom plate of the screen cage 2. A mounting plate 41 is fixed to one end of the slide rail 4. The mounting plate 41 is a circular plate that can be inserted into the central hole 23. A third threaded hole 42 is provided on the mounting plate 41, and a fourth threaded hole 52 is provided on the rotating plate 5. A second bolt 43 is provided on the mounting plate 41. The second bolt 43 passes through the third threaded hole 42 and is threadedly connected to the fourth threaded hole 52. The second bolt 43 is also threadedly connected to the third threaded hole 42.

[0022] A connecting plate 31 is fixed to the side of the disassembly housing 3 near the bottom plate of the screen cage 2. A slide rail 4 passes through the connecting plate 31, and a third bolt 32 is provided on the connecting plate 31. The third bolt 32 can pass through the connecting plate 31 and be threaded into the first threaded hole 21. A sliding hole 33 is provided in the disassembly housing 3, through which the slide rail 4 passes, allowing the disassembly housing 3 to slide along the length of the slide rail 4. A pulley group 6 is rotatably connected to the wall of the sliding hole 33. The pulley group 6 includes eight pulleys 61, four of which are located above the slide rail 4, and the other four are located below the slide rail 4, contacting the slide rail 4. The pulleys 61 facilitate the sliding of the disassembly housing 3 along the slide rail 4. A handle 34 is fixed to the disassembly housing 3. Pulling the handle 34 outwards pulls the disassembly housing 3 and the screen cage 2 together outwards.

[0023] The implementation principle of Embodiment 1 of this utility model is as follows: When it is necessary to disassemble the screen cage 2, first place the mounting plate 41 on the slide rail 4 into the center hole 23, and fix the mounting plate 41 to the rotating plate 5 with the second bolt 43; then, remove the first bolt 22, slide the disassembly housing 3 along the slide rail 4, and fix the connecting plate 31 to the screen cage 2 with the third bolt 32. Pull the handle 34 outward to pull the disassembly housing 3 and the screen cage 2 outward together to carry out the disassembly operation. If it is necessary to replace the screen cage 2, after removing the original screen cage 2, fix the new screen cage 2 with the disassembly housing 3, slide it along the slide rail 4 towards the bottom of the slag filter housing 1, and when the bottom plate of the screen cage 2 contacts the rotating plate 5, remove the third bolt 32, and fix the bottom plate of the screen cage 2 to the rotating plate 5 with the first bolt 22.

[0024] With the device of this invention, one person can complete the dismantling of the screen cage 2. The operation is simple and improves the efficiency of dismantling and installing the screen cage 2. Using this dismantling device greatly improves the safety factor of construction and solves the problem that the screen cage 2 has no lifting lugs inside and requires human assistance, which is inconvenient.

[0025] Embodiment 2 of this utility model

[0026] Reference Figure 5 The difference from Embodiment 1 is that, compared with Embodiment 1, the connection method between the disassembly housing 3 and the bottom plate of the screen cage 2 is different in Embodiment 2. The slide rail 4 is cylindrical and passes through the sliding hole 33 of the disassembly housing 3, allowing the disassembly housing 3 to rotate along the axis of the slide rail 4. The second bolt 43 is an internal hex bolt, and the third threaded hole 42 is a countersunk bolt hole.

[0027] Two plug-in blocks 35 are fixed on one side of the disassembly housing 3 near the bottom plate of the screen cage 2. The two plug-in blocks 35 are symmetrically arranged about the center of the disassembly housing 3, and each plug-in block 35 is a magnetic block. Two mounting blocks 7 are fixed on the bottom plate of the screen cage 2. Each mounting block 7 has a plug-in groove 71, and the two mounting blocks 7 are spaced 180 degrees apart. The mounting blocks 7 are made of iron. One plug-in block 35 corresponds to one plug-in groove 71 on the mounting block 7, and the plug-in block 35 and the plug-in groove 71 are plugged in and engaged. After the plug-in block 35 is inserted into the plug-in groove 71, the plug-in block 35 can be attracted to the groove wall of the plug-in groove 71, and force is required to separate the two.

[0028] The implementation principle of Embodiment 2 of this utility model is as follows: When disassembling the screen cage 2, first fix the mounting plate 41 on the slide rail 4 to the rotating plate 5, then install the disassembly housing 3 on the slide rail 4, slide the disassembly housing 3 along the slide rail 4 towards the bottom plate of the screen cage 2, and when the bottom of the disassembly housing 3 contacts the mounting plate 41, rotate the disassembly housing 3 so that the insertion block 35 is inserted into the insertion slot 71, and then pull the handle 34 outward to remove the screen cage 2.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
