Description

(54) SETTING FOR DRYING TRANSFORMER PANTS

BECOME

The invention relates to a technique of drying metal tapes after coating their surface and can be used in metallurgy. A known installation for drying transformer steel belts, comprising a belt coater, squeezing rollers, a through-passage drying chamber, and mounted on a movable frame that has a trace & the device, the cutting mechanism and the iJ iScTBo device for pulling the tape and on the threshing device in the form of a drum / 13. The disadvantage of the installation is considerable power consumption associated with a significant mass of its moving parts, as well as the need for a long stop of the moving tape when Removing the wound roll and then filling the cut end into a single drum. The purpose of the invention is to reduce energy costs by reducing the weight of moving parts and reducing the duration of stopping of the tape being dried. This is achieved by the fact that the drying chamber is fixed and has a flap located on the movable frame at the input, and the winding device additionally contains a second drum located from the first one at a distance equal to 6-18 of its diameter drums, is located at an angle of 4-12 to the plane of the tape. The drawing shows an installation diagram for drying the belt of transformer steel. The installation comprises a storage tank 1, hydraulic pumps 2j valve 3, spray coating nozzles 4, squeezing rollers 5, a through-passage drying chamber 6, a moving frame 7 on which a drying chamber 8 is installed, a belt tightening device 9, a mechanism

10 cuts, hydraulic lift

11, for driving the carcass 7, winding drums 12 and 13, with the second drum being located from the first one at a distance equal to 6-18 of its diameter, with rolls 14, 15 of the belt 16, the guide belts 17 and 18.

The installation works as follows.

By means of a hydraulic pump 2, a coating, for example, a suspension of magnesium oxide, from tank I through valve 3 enters nozzles 4 and is applied to a non-tall strip 16. Pro Tape 16 pro codises through squeezing rollers 5 and moves contactlessly through drum 12 to the drum 12, where the coil 14 is wound. As the diameter of the roll 14 increases, the angle of movement of the belt 16 relative to the horizontal plane changes. WITH . help a known tracking device, for example, operating according to the principle of a photoresistor, and a commanding device to the hydraulic lift 11 is continuously supplied - signal | which actuates it to be locked in the rise simultaneously with the plane of the belt 16 of the frame 7 with the drying chamber 8 installed on it, the drying chamber device 9, the belt tightening and the cutting mechanism 10.

When the roll 14 reaches the specified size, the movement of the belt 16 is stopped for 5-10 seconds. The device 9 fixes the tape 16 and includes the cutting mechanism 1Q. The device 9 pushes the end of the tape 16 with the help of the guide 17 to the drum 13. After the tape 16 is fixed on the winding drum 13, the device 9 stops fixing the tape 16, starts the non-contact movement of the tape 16 and winds it into wheel 15. The lifting of the frame 7 with the valve 8 installed on it, the device 9 and the mechanism 10 is mounted.

The removal of the roll 14 from the drum 12 occurs simultaneously with the winding

roll 15. When roll 15 reaches a predetermined size, the device 9 and the cutting mechanism 10 are turned on, the frame 7 is set to the initial position ,.

The mite 16 is pulled to the drum 12 with the help of the charging belt 18, and the cycle is repeated.

Stationary fixing drying

the camera and the presence of the flap reduces power consumption and simplifies installation.

The presence of two drums in the winding device increases reliability

operation of the plant for drying transformer steel belts and repeatedly reduces the time it stops.

Claims (2)
