Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further details to the present invention：
Embodiment 1
The invention discloses a kind of horizontal centrifuge pipe die cooling device, the pipe die for the horizontal centrifuge to pouring cast-steel pipe enters
The cooling device of the accurate cooling of row.The cooling device is included along axially arranged two sprays positioned at pipe die both sides of centrifuge
Frame 1 and the spray thrower on spraying rack 12；The one end of height regulating arm 5 for adjusting vertical position is fixed with centrifuge retaining wall
Connection, the other end is fixedly connected with spraying rack 1；Company is fixed in the one end of left and right adjusting arm 4 and centrifuge retaining wall for adjusting radial position
Connect, the other end is fixedly connected with spraying rack 1；Spray thrower 2 is connected by water inlet pipe 7 with the total valve 8 of water inlet, is set on water inlet pipe 7
Put water heated flow control valve 3；Present invention additionally comprises cooling device control system.The schematic perspective view of cooling device is shown in Fig. 1, figure
2, the front view of cooling device is shown in Fig. 3, and the rearview of cooling device is shown in Fig. 4.Fig. 1 and Fig. 2 merely illustrate the spraying rack 1 of side
And corresponding other parts.
The opening and closing of cooling device control system control water heated flow control valve 3 in the present invention, also including with cooling device
The connected temperature measuring head 9 being in contact with pipe die outer wall of control system communication, spray thrower 2, water heated flow control valve 3, temperature measuring head 9 three
The number of person is consistent, i.e., each spray thrower 1 controls cooling water flow, each water by single water heated flow control valve 3
Warm formula flow control valve 3 keeps communication connection with single temperature measuring head 9, receives the temperature of the pipe die outer wall of feedback, and adjustment is opened
Close degree.Cooling device control system of the invention can also control height regulating arm 5 and left and right adjusting arm 4.
Spray thrower 1 is the stainless steel tube of closed at both ends in the present invention, has been mounted side by side in the side of stainless steel tube some equal
The nozzle 2-1 of even arrangement, the water inlet connected with water inlet pipe 7 is set in relative opposite side, and concrete structure is as shown in Figure 5.
The setting form of spray thrower has two kinds in the present invention.The number of the spray thrower 2 on each spraying rack 1 could be arranged to
Three, three word orders on spraying rack 1 of spray thrower 2.The spray thrower 2 at the two ends of spraying rack 1 is located in this kind of set-up mode
Length is consistent, and the length of the spray thrower 2 in the middle of spraying rack 1 is the 4~8 of the length of the spray thrower 2 for being located at the two ends of spraying rack 1
Times.Each spray thrower 1 controls the flow of cooling water by single water heated flow control valve 3.The setting can be realized to pipe
Mould both ends and center section carry out different degrees of cooling, so that the both ends and center section of pipe in ensureing pipe die are equal
Can be cooled down according to cooling requirement, be consistent the overall cooling velocity of pipe, it is ensured that the quality inside pipe.
Spray thrower in the present invention has another setting form, specific as follows：The length of each spray thrower 2 is consistent
, length value takes less numerical value, specifically the length of spray thrower 2 can be set into 30~40cm.According to the length of spraying rack 1
Several spray throwers 1 are installed to 1 on spraying rack.Each spray thrower 1 controls to cool down by single water heated flow control valve 3
The flow of water, at the same spray thrower 1 whether water flowing can also be controlled by water heated flow control valve 3.The setting form can make cold
But device adapts to the pipe die of different length, if the length of pipe die is smaller, can close the spray thrower of the position for using less than
1.The number of spray thrower 1 and temperature measuring head 9 accordingly increases under the setting form, therefore the number of pipe die outer wall detecting temperature point also accordingly increases
Plus, so as to realize that pipe cooling is realized more being accurately controlled.
Each spraying rack 1 preferentially is set to adjust vertical position by 2 height regulating arms 5 in the present invention, each spraying rack 1
Radial position is adjusted by 2 left and right adjusting arms 4.The setting ensure that spraying rack 1 is more steady in adjusting position, to pipe
During mould spraying cooling, spraying rack 1 can keep stabilization.Height regulating arm 5 and left and right adjusting in specific implementation process
Arm 4 is disposed as hydraulic stem.The stroke of hydraulic stem is adjusted by cooling device control system.
Cooling water recovering tray 6 also is set in the underface of pipe die in the present invention, between water inlet pipe 7 and cooling water recovering tray 6
Connected by return pipe.The setting can be reused to cooling water, reduce the waste of resource, reduced and be produced into
This.Simultaneously, additionally it is possible to ensure the neat and tidy on production scene ground.
Use process of the invention is as follows：Before production, first adjusted by adjusting height regulating arm 5 and left and right according to pipe die size
Spraying rack 1 is adjusted to correct position by joint arm 4, and according to production specification（Such as pipe wall thickness）Adjustment water heated flow control valve 3
Regulation temperature, waits pouring molten steel to enter after pipe die to open the total valve 8 of water inlet, and cooling device carries out spraying cooling to pipe die, until
Pipe drops to the total valve 8 that water inlet is closed after suitable temperature, ejector sleeve.Temperature measuring head 9 is by measuring pipe die during spraying cooling
The temperature of outer wall simultaneously feeds back to cooling device control system and adjusts the cooling water flow of each spray thrower 2.
The present invention by height regulating arm is set and left and right adjusting arm spraying rack can be carried out vertical position and relative to
The regulation of the radial position of pipe die, makes spray thrower that spraying cooling closely can be kept to the pipe die of different-diameter size, carries
The effect of spraying cooling high.
The injection flow rate of spray thrower is by cooling control system control in the present invention, by water heated flow control valve and temperature measuring head
Cooperation carry out the control of injection flow rate according to actual pipe die temperature, water consumption is not only reduced, while can realize to cold
But the precise control of process, it is ensured that the quality of casting.
