Abstract
The utility model discloses a casting pipe water-cooling system on a centrifugal casting machine, which comprises a water inlet pipeline arranged outside of a centrifugal machine body and a water outlet cooling pipeline arranged inside the centrifugal machine body. A spraying head is arranged on the water outlet cooling pipeline. The key is that the water outlet cooling pipeline is divided into three sections, and an independent water inlet is assorted on every section of the water outlet cooling pipeline. Arc water pipes spraying upward are respectively arranged at the left end of the water outlet cooling pipeline at the left side and the right end of the water outlet cooling pipeline at the right side. By using the utility model, a casting pipe can be cooled in a subsection way, and the cooling effect is good. Not only the product quality and the production efficiency are improved, but also the use life of a module can be improved.
Description
Technical field
The utility model relates to a kind of cast tube water-cooling system that is used on the centrifugal casting machine, specifically is applied on DN100～300 water-cooling type ductile iron pipe centrifuges.
Background technology
At present, the water-cooling pattern of DN100～300 water-cooling type ductile iron pipe casting machines adopts both sides water spray cooling, and inner cooling water pipe is a monoblock type siphunculus, constantly opens the downward spraying cooling water of arc water pipe that the end is provided with in the middle of it.Cooling water is only from the bellmouth water inlet of cast tube, then from the socket water outlet of cast tube.In the production, the socket wall thickness of cast tube, the unit length iron water amount is bigger, and heat energy is many, so the cooling capacity that needs is just big; And socket is compared weak point cool time owing to pour into a mould at last with other positions, and the cooling capacity that needs is also bigger.And present water-cooling system can't be carried out the segmentation cooling as required, and cooling effect is poor, and stoma tube is many, and production efficiency is low.
The utility model content
The technical problems to be solved in the utility model provides a kind of cast tube water-cooling system that is used on the centrifugal casting machine, and its sectional cools off cast tube, good cooling results.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of cast tube water-cooling system that is used on the centrifugal casting machine, comprise the inlet pipeline of being located at the centrifuge machine external body and the water outlet cooling line of being located at centrifuge body inside, on described water outlet cooling line, be provided with spray head, its key technology is that described water outlet cooling line is divided into three sections, the supporting independently water inlet that is provided with on every section water outlet cooling line.
Preferably, the right-hand member of the water outlet cooling line on the water outlet cooling line left end in left side and right side is equipped with the upwards arc water pipe of spray.
Preferably, above-mentioned cast tube water-cooling system is supporting to be provided with three delivery ports, and delivery port is arranged at the middle and upper part of centrifuge body.
Preferably, above-mentioned inlet pipeline is equipped with flow control valve.
Preferably, the length ratio of the water outlet cooling line on the water outlet cooling line of the water outlet cooling line in left side, centre and right side is 3: 1: 2.
Adopt the beneficial effect that technique scheme produced to be: the utility model is divided into three sections with the water outlet cooling line of inside, and every section water outlet cooling line is supplied water by water inlet separately, can carry out the controlled cooling of segmentation, good cooling results to cast tube as required; Further improvement is equipped with the arc water pipe at two ends, allow cooling water upwards spray from the bottom, mould is cooled off, thereby form cold water at two ends and advance the flow direction that hot water goes out from top, good cooling results from the bottom, chilling temperature is even, reduce percent defective, can improve cooling effectiveness, thereby enhance productivity; By water inlet and supporting with it delivery port are divided into three the tunnel, and on the water route, upstream of water inlet, flow control valve is installed, can be carried out the automatic adjustment of water yield size as required, improved cooling effect; The utility model is owing to can guarantee that each position variations in temperature of mould reaches unanimity, and it is excessive to avoid local temperature to change, and thermal deformation is inhomogeneous and produce micro-crack, the service life of having improved mould.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
At present, the water outlet cooling line of centrifuge body inside does not have segmentation in the water-cooling system of cast tube, but siphunculus, on the water outlet cooling line, be connected with spray head, only be provided with a water inlet and a delivery port in the water route, can not carry out the segmentation cooling according to the needs of producing, thereby have a lot of drawbacks.Therefore the utility model improves its structure.
Referring to accompanying drawing 1, comprise the inlet pipeline 4 of being located at centrifuge body 9 outsides and the water outlet cooling line 11 of being located at centrifuge body 9 inside in its structure, on water outlet cooling line 11, be provided with spray head 10, water outlet cooling line 11 is divided into three sections, supporting independently water inlet 5 and three supporting delivery ports 3 of being provided with on every section water outlet cooling line 11, delivery port 3 is arranged at the middle and upper part of centrifuge body 9, the cold water of coming in from water inlet 5 can cool off fully like this, just can spill out then, prevent from that a part of cold water from also not cooling off just to have flowed from delivery port fully to go out at delivery port.The inflow of each water inlet 5 can be regulated by corresponding flow control valve 6, and the big I of its water yield is regulated flexibly according to leaving water temperature and rhythm of production.Flow control valve 6 is installed on the outside inlet pipeline 4, is provided with between inlet pipeline 4 and each water inlet.Inlet pipeline 4 links to each other with corresponding inner water outlet cooling line by flange.
Referring to accompanying drawing 1 and accompanying drawing 2, be equipped with the upwards arc water pipe of spray at the right-hand member of the water outlet cooling line on the water outlet cooling line left end in left side and right side.The arc water pipe at two ends disconnects from foot, and cold water is upwards sprayed to mould from lower circumference, and mould is cooled off, and forms cold water at two ends and advances the flow direction that hot water goes out from top from the bottom.
Referring to accompanying drawing 1, the length ratio of the water outlet cooling line of the water outlet cooling line in left side, centre and the water outlet cooling line on right side is 3: 1: 2.In the production, according to product structure and process characteristic with the length allocation of water outlet cooling line 11 each sections of inside be: the water outlet cooling line in left side accounts for 1/6 of length overall, middle water outlet cooling line accounts for 1/2 of length overall, and the water outlet cooling line on right side accounts for 1/4 of length overall.(the position relation on left side, centre and right side is as the criterion with accompanying drawing 1).
