Detailed description of the invention
Structure of the present utility model, feature and other objects is understood further in order to enable auditor, preferred embodiment appended by now combining is accompanied by accompanying drawing and is described in detail as follows, embodiment illustrated by this accompanying drawing is only for illustration of the technical solution of the utility model, and non-limiting the utility model.
First, please refer to Fig. 1 and Fig. 3, as shown in figures 1 and 3, damping roller temperature control device of the present utility model is specially for the three-roller calendar with three rollers, three damping rollers are provided with three independent temperature control systems controlled respectively accordingly, roller temperature control device is made up of the temperature control system be independently arranged on each roller, and each temperature control system comprises water tank 1, heat exchange case 2, cold doubtful device 3 and vertical multi-stage centrifugal pump 4.Wherein, water tank 1 is connected with cold doubtful device 3, thus form an independently external water circulation system, vertical multi-stage centrifugal pump 4 is connected with the water inlet of roller, thus water is filled with in roller, form the independently roller temperature lowering water circulatory system, for water circulation flowing provides power, the water that cold doubtful device 3 from the water and external water circulation system of vertical multi-stage centrifugal pump 4 outflow the roller temperature lowering water circulatory system flows out carries out heat exchange in heat exchange case 2, and the water in the pair roller temperature lowering water circulatory system is lowered the temperature.
As can be seen here, water is filled with in roller by vertical multi-stage centrifugal pump 4 by damping roller temperature control device of the present utility model, and under the driving of vertical multi-stage centrifugal pump 4, water flows out from roller, realizes lowering the temperature to damping roller.The water be filled with in roller is cold water, lower the temperature through roller pair roller, become hot water and flow out from roller, hot water is when flowing through heat exchange case 2, heat exchange is carried out with the water flowed through in the external water circulation system of heat exchange case 2 simultaneously, now, the water in external water circulation system was processed by condenser 3, was therefore cold water, after heat exchange, water in the roller temperature lowering water circulatory system turns cold, and again by vertical multi-stage centrifugal pump 4 suction roller, continues pair roller and lowers the temperature.And the water in external water circulation system enters water tank 1 after absorbing heat, and then it is cooled to enter condenser 3, so circulates.Water in two circulatory systems does not mix mutually, just carries out exchange heat at heat exchange case.In addition, in the utility model, the power in external water circulation system comes from water pump equally, and the water pump of the utility model to outside water circulation system does not have particular/special requirement.
As shown in Figure 2, in preferred version of the present utility model, in three independently the damping roller temperature lowering water circulatory system, the water inlet of each damping roller and delivery port can be separately installed with Pressure gauge 5, in order to detect discharge, realize the controlled of pair roller cooling.It should be noted that, Pressure gauge may be used for the amount detecting the water of circulation in roller, and can judge according to this amount and the circulation of controlled cooling model water, cooling water circulation is more, and the cooling of pair roller is more timely, and cooling effect is better.In the present embodiment, be all separately installed with Pressure gauge at the water inlet of three rollers and delivery port respectively, exactly for the ease of controlling respectively the cooling of three rollers in real time simultaneously.
In addition, as shown in Figure 1, in another program of damping roller temperature control device of the present utility model, cold doubtful device 3 in vertical multi-stage centrifugal pump 4 also respectively in the roller temperature lowering water circulatory system and external water circulation system is provided with pneumatic operated valve 6, utilizes pneumatic operated valve 6 can control unlatching or the closedown of water circulation.Meanwhile, also in the bottom of roller temperature control device, pulley 7 is installed, thus is convenient to mobile roller temperature control device.
In practice is produced, the heat distributed due to the central roll in three rollers is many, therefore, in further improvement of the utility model scheme, in the temperature control system corresponding with central roll, be provided with the condenser of two series connection, temperature in order to strengthen central roll controls, owing to strengthening the cooling of centring roll especially, increase the speed that water is cooled, increase the cooling water flow flux of central roll simultaneously, the heat of central roll can be passed away as soon as possible, thus ensured normally carrying out of production, the demand of high-speed production can be met.
It is to be understood that, above-mentioned utility model content and detailed description of the invention be intended to prove the utility model the practical application of technical scheme is provided, should not be construed as the restriction to the utility model protection domain.Those skilled in the art in spirit of the present utility model and principle, when doing various amendment, equivalent replace or improve.Protection domain of the present utility model is as the criterion with appended claims.
