Description

Technical Field

[0001] This utility model relates to the field of water-cooled roller sealing technology, and in particular to an end face sealing mechanism for stainless steel water-cooled rollers. Background Technology

[0002] Stainless steel water-cooled rollers typically refer to rotating shaft components used for industrial cooling or transmission. The end-face sealing mechanism of water-cooled rollers and cooling shafts is a key component ensuring their efficient and stable operation, especially in high-temperature, high-pressure, or corrosive media environments. The rotating ring rotates synchronously with the water-cooled roller and is usually made of stainless steel or hard alloy, with a surface requiring high wear resistance and corrosion resistance. The stationary ring is fixed to the equipment housing and is typically made of graphite, silicon carbide, or ceramic materials, possessing good self-lubricating properties and high-temperature resistance.

[0003] The existing water-cooled continuous casting machine roller conveyor, due to the high temperature during continuous casting, not only affects the service life of the equipment, increases maintenance, and affects production efficiency, but also increases the labor intensity of workers and deteriorates working conditions and environment.

[0004] An existing patent (publication number: CN203470866U) discloses a water-cooled roller conveyor for a continuous casting machine. Its water inlet pipe extends into the interior of the left roller through a central through-hole in the left roller shaft. The water inlet pipe section inside the roller has a row of upward-facing spray holes, and the water inlet pipe is sealed and fixed to the left bearing cover. Its water-cooling structure is simple, which not only improves the service life of the equipment but also creates a better working environment, promoting civilized production and increasing production efficiency.

[0005] While existing patents offer solutions to the aforementioned problems that possess advantages such as simple water-cooling structure, extended equipment lifespan, improved working environment, and greater efficiency and civilized production, their sealing performance is relatively poor. Because the cooling water needs to enter the water-cooled roller through a transmission pipe, and is only sealed by a single sealing ring, this ring is prone to wear after prolonged use, thus reducing the sealing effect. Summary of the Invention

[0006] The purpose of this utility model is to provide an end-face sealing mechanism for stainless steel water-cooled rollers. When cooling water passes through the first and second sealing elements, the water pressure during the transportation of cooling water will push the movable plate to move slightly, causing the sealing ring to be tightly attached to the outer surface of the first sealing element and the transmission pipe, thereby achieving a better sealing effect. When the sealing ring is worn, the compression spring can always press the movable plate to ensure that the sealing ring is tightly attached to the inner wall of the first sealing element, effectively improving the sealing effect and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an end face sealing mechanism for a stainless steel water-cooled roller, comprising a water-cooled roller body, both ends of which are connected to a transmission pipe, and the outer surfaces of the two transmission pipes are provided with sealing components for sealing, and the lower end of the sealing components is provided with a conveying component for conveying coolant.

[0008] The sealing assembly includes a first sealing element, which is respectively installed on the outer surface of the two transmission pipes. A second sealing element is movably connected to the lower end of the first sealing element. A sealing ring is installed on the inner wall of both the second sealing element and the first sealing element. The sealing ring has an L-shaped structure. A movable plate is fixed to the side wall of the sealing ring. A fixing rod that is fixedly connected to the first sealing element passes through the inner wall of both the sealing ring and the movable plate.

[0009] Preferably, the outer surface of the fixed rod is fitted with a compression spring that abuts against the movable plate, and the end of the compression spring abuts against a limiting block that is integrally fixed with the fixed rod.

[0010] Preferably, both the second seal and the first seal have a fixed bearing sleeved on the outer surface of the transmission tube.

[0011] Preferably, both ends of the inner walls of the second seal and the first seal are provided with positioning grooves, and a positioning ring fixed on the transmission tube is interference-fitted inside the positioning groove.

[0012] Preferably, the outer surface of the transmission tube has a through hole that communicates with the second seal and the first seal.

[0013] Preferably, the conveying assembly includes a fixing plate, and the fixing plate is provided in two sets. The two sets of fixing plates are respectively fixed to the outside of the second seal and the first seal. One side of one set of fixing plates is equipped with a fixing bolt that is threadedly connected to the other set of fixing plates. The lower surface of the second seal is connected to a conveying pipe, and the end of the conveying pipe is connected to a conveying pump.

[0014] Preferably, a drain pipe is connected to one side of the transmission pipe, and a flow cavity is formed inside the water-cooled roller body.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the set sealing components, when the cooling water passes through the first and second sealing components, the water pressure will push the movable plate to move slightly, causing the sealing ring to be tightly attached to the outer surface of the first sealing component and the transmission pipe, thus achieving a better sealing effect. When the sealing ring is worn, the compression spring can always press the movable plate to ensure that the sealing ring is tightly attached to the inner wall of the first sealing component, effectively improving the sealing effect.

[0017] 2. Through the set conveying assembly, the conveying pump draws out the cooling water and delivers it to the first and second seals through the conveying pipe. By unscrewing the fixing bolts on the fixing plate, the first and second seals can be released from the transmission pipe, thus facilitating the maintenance of the internal parts.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 An end-face sealing mechanism for a stainless steel water-cooled roller includes a water-cooled roller body 1, both ends of which are connected to a transmission pipe 2. The outer surfaces of the two transmission pipes 2 are provided with sealing components for sealing, and the lower end of the sealing components is provided with a conveying component for conveying coolant.

[0028] The sealing assembly includes a first seal 3, which is respectively installed on the outer surface of the two transmission pipes 2. A second seal 31 is movably connected to the lower end of the first seal 3. Sealing rings 32 are installed on the inner walls of both the second seal 31 and the first seal 3. The sealing rings 32 have an L-shaped structure. A movable plate 33 is fixed to the side wall of the sealing ring 32. A fixing rod 35, which is fixedly connected to the first seal 3, passes through the inner walls of both the sealing ring 32 and the movable plate 33. The outer surface of the fixing rod 35 is fitted with abutting against the movable plate 33. The compression spring 34 is connected, and the end of the compression spring 34 abuts against a limiting block 36 that is integrally fixed with the fixing rod 35. The interior of the second sealing member 31 and the first sealing member 3 are both connected to a fixed bearing 37 that is sleeved on the outer surface of the transmission tube 2. The two ends of the inner wall of the second sealing member 31 and the first sealing member 3 are provided with positioning grooves 38. The positioning grooves 38 are interference-fitted with positioning rings 39 that are fixed on the transmission tube 2. The outer surface of the transmission tube 2 is provided with a through hole 4 that communicates with the second sealing member 31 and the first sealing member 3.

[0029] By adopting the above technical solution, before using the end-face sealing mechanism for stainless steel water-cooled rollers, the water-cooled roller body 1 is first assembled into a suitable position. Then, the output shaft of the external drive device is connected to the transmission pipe 2 via a coupling, so that the external device can drive the water-cooled roller body 1 to rotate. When the cooling water passes through the first seal 3 and the second seal 31, due to the certain pressure of the cooling water during transportation, the water pressure will push the movable plate 33 to move slightly, thereby causing the sealing ring 32 to tightly adhere to the outer surface of the first seal 3 and the transmission pipe 2, achieving a better sealing effect. Furthermore, through the compression spring 34 on the fixed rod 35, when the sealing ring 32 wears, the compression spring 34 can always... Finally, the movable plate 33 is pressed tightly to ensure that the sealing ring 32 is tightly attached to the inner wall of the first sealing element 3, effectively improving the sealing effect. The limit block 36 can play a limiting role, and the fixed bearing 37 set in the first sealing element 3 and the second sealing element 31 can ensure that the sealing assembly will not rotate when the transmission tube 2 rotates. By unscrewing the fixing bolt 51 on the fixing plate 5, the fixing of the first sealing element 3 and the second sealing element 31 can be released, so that the first sealing element 3 and the second sealing element 31 can be removed from the transmission tube 2, which facilitates the maintenance of the internal parts. The positioning groove 38 and the positioning ring 39 can play a positioning and assembly role, and also play an auxiliary sealing role.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the conveying assembly includes a fixing plate 5, which has two sets. The two sets of fixing plates 5 are respectively fixed to the outside of the second seal 31 and the first seal 3. One side of one set of fixing plates 5 is equipped with a fixing bolt 51 that is threadedly connected to the other set of fixing plates 5. The lower surface of the second seal 31 is connected to a conveying pipe 52. The end of the conveying pipe 52 is connected to a conveying pump 53. One side of the transmission pipe 2 is connected to a drain pipe 6. A flow cavity 7 is opened inside the water-cooled roller body 1.

[0031] By adopting the above technical solution, the conveying pump 53 is connected to an external water source. The conveying pump 53 draws out cooling water and delivers it through the conveying pipe 52 to the first seal 3 and the second seal 31. Since there are flow cavities inside the first seal 3 and the second seal 31, the cooling water can enter through the through hole 4 on the transmission pipe 2 and then flow into the flow cavity 7 inside the water-cooled roller body 1, so that the water-cooled roller body 1 cools the material. Furthermore, the cooling water continuously delivered to the inside through the drain pipe 6 on another set of sealing components can be discharged and collected through the drain pipe 6, thus facilitating recycling.

[0032] Working principle: Cooling water enters the transmission pipe 2 through the through hole 4 and flows into the flow chamber 7 inside the water-cooled roller body 1, cooling the material. The cooling water continuously supplied to the interior is discharged and collected through the drain pipe 6 on another set of sealing components, facilitating recycling. When the cooling water passes through the first seal 3 and the second seal 31, it is under pressure, which pushes the movable plate 33 to move slightly, causing the sealing ring 32 to press tightly against the first seal 3 and the outer surface of the transmission pipe 2, achieving a good sealing effect. The compression spring 34 on the fixed rod 35 prevents the sealing ring 32 from wearing out. The compression spring 34 can always press the movable plate 33, thereby ensuring that the sealing ring 32 is tightly attached to the inner wall of the first sealing element 3, improving the sealing effect. The limit block 36 can play a limiting role, and the fixed bearing 37 set in the first sealing element 3 and the second sealing element 31 can ensure that the transmission tube 2 will not drive the sealing assembly to rotate when it rotates. By unscrewing the fixing bolt 51 on the fixing plate 5, the fixing of the first sealing element 3 and the second sealing element 31 can be released, so that the first sealing element 3 and the second sealing element 31 can be removed from the transmission tube 2, which facilitates the maintenance of the internal parts. The positioning groove 38 and the positioning ring 39 can play a positioning and assembly role.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
