Embodiment Construction

[0011] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0012] At present, the water cooling pipeline inside the centrifuge body in the cast-pipe water cooling system is not segmented, but a through-pipe. A sprinkler head is connected to the water cooling pipeline, and only one water inlet and one outlet are set in the waterway. The nozzle can not be cooled in stages according to the needs of production, so there are many disadvantages. Therefore, the present invention improves its structure.

[0013] see attached figure 1 , its structure includes a water inlet pipeline 4 arranged outside the centrifuge body 9 and an outlet water cooling pipeline 11 arranged inside the centrifuge body 9. 11 is divided into three sections, and each section of water cooling pipeline 11 is provided with an independent water inlet 5 and three matching water outlets 3. The water outlet 3 is arranged in the uppe...

Abstract

The invention discloses a cast tube water cooling system used for a centrifugal casting machine, which comprises an inflow pipeline arranged outside a centrifuge body and an effluent cooling pipeline arranged inside the centrifuge body, wherein the effluent cooling pipeline is provided with a spray header, and is characterized in that the effluent cooling pipeline is divided into three sections, each section of the effluent cooling pipeline is provided with an independent water inlet, and three matched water outlets are arranged on the top and middle part of the centrifuge body; and arch-shaped water pipes capable of jetting water upwards are arranged at the left end of the effluent cooling pipeline at the left side and at the right end of the effluent cooling pipeline at the right side. By the invention, a cast tube can be cooled section by section with good cooling effect, thus improving the product quality and production efficiency and enhancing the service life of a die.

Description

technical field [0001] The invention relates to a water-cooling system for a cast pipe used in a centrifugal pouring machine, and is specifically applied to a DN100-300 water-cooled ductile iron pipe centrifuge. Background technique [0002] At present, the water cooling method of DN100~300 water-cooled ductile iron pipe casting machine adopts water spray cooling on both sides, the internal cooling water pipe is an integral through pipe, the middle of which is not disconnected, and the arc-shaped water pipe set at the end sprays cooling water downward. The cooling water only enters from the socket of the casting pipe, and then comes out from the socket of the casting pipe. In production, the wall thickness of the socket of the cast pipe is large, the amount of molten iron per unit length is large, and the heat energy is large, so the required cooling capacity is large; and the socket has a shorter cooling time than other parts due to the final pouring, and the required cooli...
