DETAILED DESCRIPTION

[0016] The utility model is described in detail according to the accompanying drawings of the specification.

[0017] like Figure 1 to Figure 4 As shown, the casting production line uses a water-cooled cooling device, including a horizontal conveyor belt for castings and a cooling water trough 6.

[0018] The casting horizontal conveyor belt includes an inlet horizontal conveying unit 4 arranged at the front end of the cooling water trough 6, an outlet horizontal conveying unit 12 arranged at the rear end of the cooling water trough 6, and a transition horizontal conveying unit 5 located between the inlet horizontal conveying unit 4 and the outlet horizontal conveying unit 12.

[0019] The transition horizontal conveying unit 5 includes a support frame 501 and a plurality of conveying rollers 502 arranged in the support frame 501. The two diagonal positions of the support frame 501 are respectively threadedly connected to the longitudinal screw 3, and the lower end of the longitudinal screw 3 is supported on the bottom surface of the cooling water tank 6 by the bearing seat 7. The cooling water tank 6 is symmetrically fixed with inverted L-shaped cantilever columns 2 at the four corners, wherein the top surfaces of two inverted L-shaped cantilever columns 2 are fixed with driving motors 1 connected to the upper ends of the longitudinal screw 3, and guide columns 11 are arranged between the top surfaces of the other two inverted L-shaped cantilever columns 2 and the bottom surface of the cooling water tank 6, and the support frame 501 is provided with guide holes corresponding to the guide columns 11.

[0020] A smoke collecting hood 9 is further provided above the support frame 501, and the top of the smoke collecting hood 9 is connected to the negative pressure pipeline 8. The smoke collecting hood 9 is a door-shaped hood, and the lower ends of the two side walls of the door-shaped hood are connected and fixed to the left and right edges of the support frame 501.

[0021] Working principle:

[0022] See also Figure 1 The cast fan bearing box 10 is sent to the transition horizontal conveying unit 5 through the inlet horizontal conveying unit 4. At this time, the transition horizontal conveying unit 5 is flush with the roller surface of the inlet horizontal conveying unit 4 and the outlet horizontal conveying unit 12.

[0023] After the fan bearing housing 10 reaches the bottom of the smoke collecting hood 9, the driving motor 1 is started, and the transition horizontal conveying unit 5 drives the fan bearing housing 10 downward and sinks below the cooling water level in the cooling water tank 6, so that the cooling water enters the inside of the fan bearing housing 10, and the cooling water directly cools the fan bearing housing 10 on both the inside and outside. During the cooling process, the generated smoke enters the smoke collecting hood 9 under the action of negative pressure, and is discharged to the filter device through the negative pressure pipeline 8, and then discharged to the atmosphere.

[0024] After cooling is completed, the driving motor 1 reverses, driving the transition horizontal conveying unit 5 and the fan bearing box 10 upward, making the roller surfaces of the transition horizontal conveying unit 5 and the outlet horizontal conveying unit 12 flush, and transporting the fan bearing box 10 along the transition horizontal conveying unit 5 and the outlet horizontal conveying unit 12 to the next process.
