Description

Technical Field

[0001] The utility model relates to the technical field of various large-scale water-cooling spiral support components of metallurgical steel enterprises, and in particular to a support roller support adjustment device for a water-cooling spiral conveyor. Background Art

[0002] The production of vanadium trioxide products requires the processing of raw material coarse slag crushing, multi-layer furnace roasting, three-cleaning and three-washing leaching and other processes. In the production process of vanadium trioxide, the roasting process is an indispensable step, and the water-cooled screw conveyor is the main key equipment for conveying roasted clinker. Figure 1 As shown, a commonly used water-cooled screw conveyor usually includes a horizontally arranged water-cooled spiral cylinder 11, and a plurality of support roller support groups are distributed below the water-cooled spiral cylinder 11 along its axial direction. Each support roller support group includes support roller supports 13 respectively arranged on both sides of the water-cooled spiral cylinder 11 (one of the support roller supports 13 is not shown in the figure), and the plurality of support roller support groups cooperate to support the water-cooled spiral cylinder 11. The support roller support 13 also has the function of driving the water-cooled spiral cylinder 11 to rotate. Specifically, a support ring 12 is arranged on the outer peripheral wall of the water-cooled spiral cylinder 11. The support roller support 13 is driven to rotate by the driving system, and then the water-cooled spiral cylinder 11 is driven to rotate through the support ring 12. The central axis at both ends of the support roller support 13 is rotatably arranged in the bearings in the bearing boxes 16 on both sides. When adjusting the height or position of the water-cooled spiral cylinder 11, a screw adjustment device 14 is usually set on the outside of the bearing box 16. The position of the bearing box 16 is adjusted by rotating the positioning adjustment screw in the screw adjustment device 14, and then the height and angle of the water-cooled spiral cylinder 11 are adjusted by moving the supporting roller 13.

[0003] At present, the fixed base that cooperates with the threaded transmission of the positioning adjustment screw in the screw adjustment device of the metallurgical steel enterprise factory in the industry is welded on the horizontal foundation on the outside of each support roller. When newly installed, the positioning screw adjustment device is flexible and effective in a short time. As time goes on during the production operation, the uninterrupted cooling water part of the water-cooling spiral (clinker is acidic) splashes and adheres to the vanadium oxide dust gradually adheres to the positioning adjustment screw thread pair of the screw adjustment device and mixes, causing the positioning adjustment bolt screw to accelerate corrosion, destroying the positioning adjustment screw thread pair, and causing the positioning adjustment screw adjustment roller to fail. The support roller is skewed and worn, which causes serious problems such as deviation, scratching, and cylinder breakage of the water-cooling spiral cylinder. Based on this, the existing technology still needs to be improved. Utility Model Content

[0022] It should be understood that the embodiments of the present invention shown in the exemplary embodiments are illustrative only. Although only a few embodiments are described in detail in the present invention, it is easy for those skilled in the art to understand that multiple modifications are feasible without actually departing from the teachings of the subject matter of the present invention. Accordingly, all such modifications should be included within the scope of the present invention. Without departing from the gist of the present invention, other replacements, modifications, changes and deletions may be made to the design, operating conditions and parameters of the following exemplary embodiments.

[0023] like Figure 2As shown, the utility model provides a water-cooled screw conveyor support roller support adjustment device, which includes a fixed base 3 and a positioning adjustment screw 2. The fixed base 3 is fixedly arranged, and is provided with a threaded guide hole extending in a first direction, and the first direction is perpendicular to the axial direction of the water-cooled screw cylinder 11 of the water-cooled screw conveyor; Figure 1 As shown, with the direction of the axis of the water-cooled spiral cylinder 11 as the left-right direction, multiple support roller brackets are arranged in sequence along the left-right direction, and the two support roller brackets 13 of each support roller bracket group are respectively arranged on the front and rear sides below the water-cooled spiral cylinder 11. The threaded guide hole on the fixed base 3 is through in the front-to-back direction. The positioning adjustment screw 2 is arranged along the front-to-back direction, and the raised thread on the positioning adjustment screw 2 is threadedly matched with the thread groove in the threaded guide hole, and the end of the positioning adjustment screw 2 close to the water-cooled spiral cylinder 11 is against the bearing box 16 at the end of the support roller bracket 13.

[0024] Among them, two protective covers 1 are also provided on the positioning and adjusting screw rod 2, and the two protective covers 1 are respectively located on both sides of the fixed base 3, so as to protect the positioning and adjusting screw rod 2. Each protective cover 1 is telescopically arranged along a first direction, and the two ends of the protective cover 1 are respectively connected to the fixed base 3 and the end of the positioning and adjusting screw rod 2, so that when the positioning and adjusting screw rod 2 moves relative to the fixed base 3, the protective cover 1 is extended or shortened under the drive of the end of the positioning and adjusting screw rod 2, and always covers the outer side of the positioning and adjusting screw rod 2.

[0025] The utility model can provide better protection effect than the traditional positioning and adjusting screw rod 2 without protection measures by arranging two protective sleeves 1 on the positioning and adjusting screw rod 2. The positioning and adjusting screw rod 2 is not easily blocked or stuck by the splashing and adhesion of cooling water and the adhesion of vanadium oxide dust. The utility model has a long service life, is stable and durable, and has a low cost.

[0026] Under the rotating pressure of tens of tons of water-cooled spiral cylinder 11 and materials, the support roller 13 is easy to loosen, and the positioning adjustment screw 2 will be subjected to a large normal external force, forcing the fixed base 3 and the positioning adjustment screw 2 to loosen and move, destroying the smooth operation of the water-cooled spiral cylinder 11, causing multiple groups of support rollers 13 to be overloaded and worn to varying degrees, causing the heavy-loaded cylinder to tilt, rub or hit adjacent equipment such as water tanks, resulting in major equipment failures that cause the entire production line to stop production, seriously restricting the normal production of the enterprise.

[0027] Based on this, Figure 2 and Figure 3As shown, in some embodiments of the utility model, the support roller adjustment device of the water-cooled screw conveyor of the present application also includes a fixed foundation (not shown in the figure), the fixed base 3 is installed on the fixed foundation, and a multi-faceted adjustment head 8 is fixedly installed at one end of the positioning adjustment screw rod 2 away from the water-cooled spiral cylinder 11. The support roller adjustment device of the water-cooled screw conveyor also includes a stop member 9, which is detachably installed on the fixed foundation, and a limiting hole 10 is provided on the stop member 9 for limiting the multi-faceted adjustment head 8. The multi-faceted adjustment head 8 can be a triangular rod, a quadrangular rod, a pentagonal rod, etc., and the limiting hole 10 matches the shape of the adjustment head 8. Specifically, as Figure 3 As shown, the adjusting head 8 is a square adjusting head, and the limiting hole 10 is a square. After the position of the positioning adjusting screw 2 is adjusted, the limiting hole 10 on the stop member 9 is horizontally inserted into the square adjusting head, and the stop member 9 is installed on a fixed basis to limit the positioning adjusting screw 2 from rotating backward due to the heavy-loaded bearing box 16 of the water-cooled spiral cylinder 11. It effectively prevents abnormal wear of the equipment caused by the displacement of the positioning adjusting screw 2, ensures the stable operation of the enterprise's water-cooled spiral cylinder 11 from a technical perspective, and provides hardware guarantee for the efficient, fast, accurate and stable operation of the enterprise's water-cooled screw conveyor, which has certain promotion value.

[0028] In some embodiments, the protective sleeve 1 is a stainless steel bellows. It has good corrosion resistance, elasticity and wear resistance, and can resist various corrosive media, such as oxidation, acid, alkali, salt, etc., which makes it more reliable and has a long service life in harsh environments. The stainless steel bellows also provides good sealing performance, effectively preventing the problem of the thread pair of the positioning adjustment screw 2 being exposed.

[0029] In some embodiments, fixed pipe clamps 4 are installed on both sides of the fixed base 3 along the first direction, the fixed pipe clamps 4 are annular, and a clamping groove is arranged on the outer circumference of the fixed pipe clamps 4. The end of the protective sleeve 1 close to the fixed base 3 is the first end, and a buckle is arranged on the first end, and the buckle is inserted into the clamping groove, so as to facilitate the installation and replacement of the protective sleeve 1.

[0030] In some embodiments, both ends of the positioning and adjusting screw 2 have a smooth rod portion 6, and the end of the protective cover 1 away from the fixed base 3 is the second end, and a retaining ring 5 is installed on the second end. The retaining ring 5 is rotatably mounted on the smooth rod portion 6 and abuts against the raised thread on the positioning and adjusting screw 2, so that when the positioning and adjusting screw 2 is adjusted, the protective cover 1 can be adaptively extended or shortened and does not rotate with the positioning and adjusting screw 2.

[0031] In some embodiments, the outer peripheral wall of the positioning and adjusting screw rod 2 is also coated with lithium-based grease 7. Applying lithium-based grease 7 on the positioning and adjusting screw rod 2 can reduce wear, prevent rust, adapt to temperature changes, and help prevent dust and other particles from entering the screw rod adjustment mechanism to avoid damage. Proper lubrication can also improve the transmission efficiency of the positioning and adjusting screw rod 2, making power transmission smoother and extending the service life of the positioning and adjusting screw rod 2.

[0032] Since there may be no position on the bearing box 16 that cooperates with the positioning adjustment screw 2, in some embodiments, the present application provides a guide for the movement of the bearing box 16 and the positioning adjustment screw 2 by setting a baffle 15. Specifically, the baffle 15 is installed at one end of the bearing box 16 away from the water-cooled spiral cylinder 11, and the baffle 15 has at least one vertical surface for abutting against the positioning adjustment screw 2. When the positioning adjustment screw 2 moves to the side close to the bearing box 16, the positioning adjustment screw 2 always abuts against the vertical surface of the baffle 15. When the support roller support 13 is parallel to the water-cooled spiral cylinder 11, the vertical surface is perpendicular to the positioning adjustment screw 2. Since one support roller support 13 corresponds to two bearing boxes 16 and two water-cooled screw conveyor support roller support adjustment devices, the support roller support 13 may not be parallel to the water-cooled spiral cylinder 11 during the adjustment of the positioning adjustment screw 2, but it will still abut against the positioning adjustment screw 2.

[0033] In some embodiments, the retaining member 9 includes a base plate and a fixing column welded on the top of the base plate. The base plate and the fixing base are detachably connected by bolts, which facilitates the installation and removal of the retaining member 9.

[0034] In some embodiments, the fixed base 3 includes a mounting plate and a threaded sleeve welded on the mounting plate. The mounting plate and the fixed base are connected by bolts to facilitate the installation and disassembly of the retaining member 9. The positioning and adjusting screw rod 2 is threadedly matched with the threaded groove inside the threaded sleeve.

[0035] In some embodiments, the protective cover 1 includes two stainless steel tubes that are slidably connected to each other, which can also provide support for the expansion and contraction of the protective cover 1.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. If the present invention is modified or replaced by equivalents without departing from the spirit and scope of the present invention, it should be included in the scope of protection of the claims of the present invention.
