Abstract
The utility model relates to a cooling water circulating device for a calender, which comprises a tap water, warm water and chilled water inlet main pipeline, a tap water, warm water and chilled water return main pipeline, a plurality of rollers and a plurality of valves, and is characterized in that one end of each roller is connected in parallel with a tap water, warm water and chilled water inlet branch pipeline and the other end of the roller is connected in parallel with a tap water, warm water and chilled water return branch pipeline; each branch pipeline is communicated with the corresponding main pipeline; and each branch pipeline is respectively provided with a control valve. The cooling water circulating device for the calender has the advantage that the variety and the amount of cooling water can be regulated through the valves, so that the temperature of the cooling water at each section is controllable and the accuracy of the temperature and the cooling setting effect of a product are greatly improved, and further, the production cost is reduced.
Description
Technical field
The utility model plastics rolling equipment field particularly relates to a kind of EGR of calender cooling water.
Background technology
In the plastics calendering production equipment, need feed cooling water to reach the effect of product approval in temperature refining and cooling section, at present, traditional cooling water system be adopt with roller between the endless form of connecting, make that like this temperature difference between each roller is big, and the temperature of single group roller is uncontrollable, and then has influenced the cooling and shaping effect of product.
Summary of the invention
The utility model is for solving the technical problem that exists in the known technology a kind of water yield is provided and the water temperature type being controlled, improve the EGR of the calender cooling water of temperature precision and product cooling and shaping effect.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the EGR of calender cooling water, comprise: running water water inlet trunk line, running water backwater trunk line, warm water water inlet trunk line, warm water backwater trunk line, chilled water water inlet trunk line, chilled water backwater trunk line, a plurality of rollers and valve, it is characterized in that: an end of described each roller is connected in parallel to running water water inlet lateral, warm water water inlet lateral and chilled water water inlet lateral, described running water water inlet lateral connects running water water inlet trunk line, warm water water inlet lateral connects warm water water inlet trunk line, chilled water water inlet lateral connects chilled water water inlet trunk line, at running water water inlet lateral, be equipped with the water inlet control valve door on warm water water inlet lateral and the chilled water water inlet lateral; The other end of described each roller is connected in parallel to the back-flowing and branched pipeline of running water, the back-flowing and branched pipeline of warm water and the back-flowing and branched pipeline of chilled water, the back-flowing and branched pipeline of running water connects running water backwater trunk line, the back-flowing and branched pipeline of warm water connects warm water backwater trunk line, the back-flowing and branched pipeline of chilled water connects chilled water backwater trunk line, on the back-flowing and branched pipeline of running water, the back-flowing and branched pipeline of warm water and the back-flowing and branched pipeline of chilled water the backwater by-pass valve control is housed respectively; Described each lateral that connects with each roller all is connected in parallel with corresponding each trunk line.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, be be connected in parallel the water inlet lateral and the back-flowing and branched pipeline of three kinds of water temperatures of each roller, and between each lateral and trunk line, be provided with by-pass valve control, like this can be by the kind and the water yield of valve regulated cooling water, make that the cooling water temperature of each section is controlled, increase substantially the degree of accuracy of temperature and the cooling and shaping effect of product, and then reduced production cost.
