Description
Technical Field
The invention relates to the field of large calenders, in particular to a mixed flow self-stirring uniform temperature type calendering roller.
Background
The glass calender is used for pressing and forming high-temperature glass by the calender roll, and the calender roll is bent or cracked under the high-temperature environment, so that the calender roll is particularly important to cool. In the prior art, cooling of the large-sized calendaring roller only carries out cavity-separating water inflow, effective temperature equalization control is not carried out on water temperature, water temperature difference of each part is caused, the use effect of the calendaring roller is caused, the instability of glass product quality is caused, the reusability of the calendaring roller is reduced, and the service life is prolonged.
Chinese patent ZL2014220440341.6 discloses a calender roll cooling water device, and although cooling control of different surfaces in the calender roll is realized, along with the increasing demand of market to the calender, especially to the large-scale calender that appears recently, it still can not solve the difference in temperature of the cooling area of the calender roll in the large-scale calender, and its structure is difficult to reduce each regional water Wen Wencha, and then influences the work effect of large-scale calender.
Disclosure of Invention
The invention aims at: aiming at the problems in the prior art, the mixed-flow self-stirring uniform-temperature type calendaring roller is provided. The mixed flow self-stirring temperature-equalizing type calender roll can reduce the difference of cooling speeds of different surfaces in the calender roll in a large calender, and realize the temperature equalization of water temperatures of all parts.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
the mixed flow self-stirring uniform temperature type calendaring roller comprises a calendaring roller body and a water through pipe, wherein a water diversion core is arranged on the axis of the calendaring roller body, the water diversion core is a cross water diversion core with an integral structure comprising four water diversion plates, the four water diversion plates of the water diversion core divide the inner space of the calendaring roller body into four water tanks, and a plurality of groups of water outlet holes are arranged on the circumference of the middle part of the water diversion core along the axial direction; the water diversion core is hollow in the direction, a water pipe with a water outlet is inserted in the water diversion core, the water outlet on the water pipe is aligned with the water outlet on the water diversion core, and water mixing ports are arranged on the four water diversion plates.
According to the preferable technical scheme, the water pipe is also provided with guide vanes which are arranged along the water flow direction.
In summary, by adopting the above technical scheme, water outlets are formed in different positions, meanwhile, a certain proportion of water mixing ports are formed in the water diversion plate, guide vanes are matched, the water flow direction is determined, when the guide vanes rotate on the calendaring rollers, according to the spiral conveying principle, the water flow speed of cooling water is self-accelerated, the fluidity is improved, the high temperature region is towards the middle temperature region, the middle temperature region is towards the low temperature region, the low temperature region is towards the water outlets, the water mixing speed of each region is accelerated, and the water temperature homogenizing speed of each region is accelerated. The internal cooling water of the rolling roller body is subjected to self-stirring and temperature equalization, and self-accelerating flow and flow directivity of the internal cooling water enable the temperature of each part in the rolling roller body to be uniform, so that the rolling roller body is prevented from being bent due to uneven heating. Meanwhile, the condition that the surface temperature of the calendaring roller body is uneven and the quality stability of glass is affected is avoided.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, so that the objects, technical solutions and advantages of the present invention will become more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1 to 3, the mixed-flow self-stirring uniform-temperature type calendaring roller comprises a calendaring roller body 1 and a water through pipe 8, wherein a water diversion core 5 is arranged on the axis of the calendaring roller body 1, the water diversion core 5 is a cross water diversion core with an integral structure comprising four water diversion plates 6, the four water diversion plates 6 of the water diversion core 5 divide the inner space of the calendaring roller body 1 into four water tanks 7, and a plurality of groups of water outlet holes 3 are arranged on the circumference of the middle part of the water diversion core 5 along the axial direction; the water diversion core 5 is hollow in the axial direction, a water pipe 5 with a water outlet 3 is inserted, the water outlet 3 on the water pipe 8 is aligned with the water outlet 3 on the water diversion core 5, and water mixing ports 9 are arranged on the four water diversion plates 7. In this embodiment, the water pipe 8 is further provided with a guide vane 10 disposed along the water flow direction.
The working principle of the invention is as follows: when the calendaring roller rotates, water in a high-temperature area in the middle of the water tank partially passes through the water mixing port, the guide vane is communicated, the flow direction is regulated, the water flows to the middle-temperature area of the water tank respectively towards the two ends of the water diversion core, cooling water in the middle-temperature area of the water tank passes through the water mixing port, the guide vane, the water partially flows to the low-temperature area of the water tank, and cooling water in the water tank flows to the water outlet. The flow mode of the four water tanks is similar. Thereby achieving the flow of cooling water and the mixing speed, solving the temperature uniformity of each part of the roller, solving the bending deformation of the calendaring roller, the surface temperature uniformity of the calendaring roller, prolonging the service life of the calendaring roller and achieving the purpose of saving the cost.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention.
