Description

Technical Field

[0001] The present invention relates to the technical field of calender rolls. Specifically, the present invention relates to a spiral cooling water core and a calender roll. Background Art

[0002] A calender is a device that produces glass with different thicknesses and widths by relatively squeezing a glass solution at more than 1400 degrees through two calender rolls. After the length of the calender roll, the main component of the calender, is increased, the existing cooling method of the calender roll cannot achieve the circulation of cooling water, resulting in a large temperature difference at each end of the calender roll. For example, if the local temperature is too high, the glass will stick to the roll, causing the glass to not be produced normally; if the cooling water circulation of the calender roll is not smooth, the calender roll will be deformed, resulting in uneven thickness of the glass, seriously affecting the quality of the glass.

[0003] The applicant found through retrieval that the Chinese patent document with the publication number 219637092U discloses a calender roll for glass processing with a cleaning structure on September 5, 2023, including a calender roll. A first roll neck is fixed at the left end of the calender roll, and a second roll neck is fixed at the right end of the calender roll. The calender roll is provided with a cleaning component and a limiting component. The cleaning component includes: a small disc, a large disc, a long rod, a brush, a scroll spring, a blocking rod, a first torsion spring, a swing rod, and a spring. The limiting component includes a linkage plate. In the normal operation of the calender roll of the glass processing calender roll with a cleaning structure, under the action of centrifugal force, the swing rod will unfold, so that it will rest on the surface of the blocking rod, enabling the first roll neck to drive the small disc to rotate. When the small disc rotates, it can tighten the scroll spring, making the scroll spring in a compressed state. When the calender roll finishes working, the scroll spring returns, driving the long rod and the brush to clean the surface of the calender roll; this device also cannot solve the above technical problems.

[0004] Therefore, in order to improve or solve at least one of the above problems, it is necessary to provide a spiral cooling water core that can achieve uniform cooling of the calender roll. Summary of the Invention

[0007] The middle part of the central tube is provided with a mounting hole; the mounting hole is communicated with the inside of the central tube; the water outlet cap includes a mounting tube; one end of the mounting tube is communicated with the mounting hole, and the other end of the mounting tube is connected with a baffle; the mounting tube is provided with water outlet holes; the water outlet holes are communicated with the inside of the mounting tube.

[0008] Both the first spiral partition plate and the second spiral partition plate are connected to the outer wall of the central tube; the spiral directions of the first spiral partition plate and the second spiral partition plate are opposite; the first spiral partition plate is provided with a first water return groove; the second spiral partition plate is provided with a second water return groove.

[0009] Both ends of the central tube are provided with tapered sleeves; one end of the central tube is provided with a first bushing, and the other end of the central tube is provided with a second bushing; the first spiral partition plate is arranged between the water outlet cap and the first bushing; the second spiral partition plate is arranged between the water outlet cap and the second bushing.

[0010] The first bushing is provided with a plurality of first water return holes; the second bushing is provided with a plurality of second water return holes; the first water return holes are communicated with the first water return groove; the second water return holes are communicated with the second water return groove.

[0011] The central tube is provided with a plurality of mounting holes; the central axes of the mounting holes are perpendicular to the central axis of the central tube; adjacent mounting holes are distributed in a staggered manner along the axial direction of the central tube; the central axes of adjacent mounting holes are perpendicular to each other.

[0012] A calendering roll includes the spiral cooling water core; it also includes a roll body; a connecting hole is provided in the roll body; the spiral cooling water core is arranged in the connecting hole.

[0013] The first bushing, the second bushing, the first spiral partition plate and the second spiral partition plate are all in tight contact with the inner wall of the roll body.

[0014] Both ends of the roll body are connected with connecting shells; a water supply pipe is provided in the connecting shells; a water outlet groove is provided between the connecting shells and the water supply pipe; the connecting shells are respectively provided with a water inlet and a water outlet; one end of the water supply pipe is connected with the tapered sleeve, and the other end of the water supply pipe is communicated with the water inlet; the first water return holes and the second water return holes are both communicated with the water outlet groove, and the water outlet groove is communicated with the water outlet.

[0015] Both ends of the roll body are provided with connecting grooves; the connecting shell is connected with a flange; the flange is connected in the connecting groove.

[0016] The beneficial effects of the present invention are:

[0017] The spiral cooling water core of the present invention includes a central pipe. Cooling water is input from both ends of the central pipe and flows out from the water outlet cap in the middle of the central pipe, thus filling the first water return tank of the first spiral partition plate and the second water return tank of the second spiral partition plate. Due to the small gap between the first spiral partition plate and the second spiral partition plate and the inner wall of the roll body of the calender roll, and the large inlet water pressure, when the calender roll rotates, the water flowing from the central pipe to the water outlet cap will flow between the outside of the central pipe and the inside of the roll body of the calender roll along the rotation direction of the first spiral partition plate and the second spiral partition plate due to the water pressure. While flowing, heat exchange is carried out on the inner wall heat of the calender roll, thereby cooling the calender roll. Since the first spiral partition plate and the second spiral partition plate rotate in left and right directions respectively, the cooling water flows out from the water outlet at both ends of the calender roll.

[0018] The cooling water circulates in a closed loop in the spiral cooling water core. Since the cooling water continuously flows through the inner wall of the roll body of the calender roll, cavitation will not be formed on the inner wall of the calender roll, thereby avoiding the formation of local high temperature on the calender roll and causing sticking of the roll, effectively ensuring uniform cooling of the calender roll and maintaining normal production.

[0019] The cooling water exits at a 90-degree direction from the water outlet cap, which will not cause local cooling of the inner wall of the roll body of the calender roll. The first spiral partition plate and the second spiral partition plate guide the cooling water to rotate in a spiral shape on the inner wall of the roll body of the calender roll. The calender roll is still rotating continuously, and the calender roll is evenly cooled, avoiding deformation of the calender roll, extending the service life of the calender roll, and improving the product quality of the glass.

[0020] When the cooling water completes the closed loop in the spiral cooling water core and flows out from the water outlet cap of the central pipe, due to the return water of the cold water between the first spiral partition plate and the second spiral partition plate, which is higher in temperature than the normal temperature water, when the water temperature passes through the central pipe, the temperature of the cooling water will rise. It is not affected by the weather temperature, and the temperature of the cooling water is easy to control. The temperature of the calender roll will be controlled by the inlet water pressure and flow rate, ensuring stable production.

[0021] When the glass melt is produced into glass products, it is completely formed by the extrusion of the upper and lower calender rolls. The temperature of the calender roll is stable, and the performance of the glass in the impact resistance test and the ball drop test of the glass is stable and improved.

[0038] The cooling water circulates in a closed loop in the spiral cooling water core. Since the cooling water continuously flows through the inner wall of the roller body of the calender roll, cavitation will not be formed on the inner wall of the calender roll, thus avoiding the formation of local high temperature on the calender roll and causing the glass to stick to the roll, effectively ensuring the uniform cooling of the calender roll and maintaining normal production; the cooling water exits from the water outlet cap 101 at a 90-degree angle, which will not cause local cooling of the inner wall of the roller body of the calender roll. The first spiral partition plate 2 and the second spiral partition plate 3 guide the cooling water to rotate in a spiral shape on the inner wall of the roller body 6 of the calender roll. The calender roll is still rotating, and the calender roll is evenly cooled, avoiding deformation of the calender roll and extending the service life of the calender roll, and improving the product quality of the glass.
