As shown in fig. 9a and 9b, the nozzle plate further comprises a support 5 detachably disposed on the bracket 21, wherein a first step 51 and a second step 52 are respectively disposed on two opposite side walls of the top of the support, and a plurality of first rolling members 53 and second rolling members 54 are respectively disposed on the step surface of the first step 51 and the step surface of the second step 52, so that the nozzle plate 3 can slide on the first rolling members 53 and the second rolling members 54 in a reciprocating manner in a second direction of the horizontal plane and is limited between the first step 51 and the second step 52; the first direction and the second direction are perpendicular.

By arranging the bracket, when the bottom of the bushing 3 abuts against the rolling member on the step surface of the bracket, an acting force is manually applied to the bushing 3, so that the bushing 3 slides on the rolling member along the second direction, i.e. the second direction is the front-back direction in fig. 5a, i.e. the sliding direction is the Y-axis direction on the horizontal plane, so as to finely adjust the position of the bushing 3. Of course, the first direction and the second direction can be changed, the bracket 21 can slide in a reciprocating and telescopic manner along the Y-axis direction, and the bushing 3 can independently slide in a reciprocating manner along the X-axis direction on the bracket. The movement of the nozzle plate 3 in the directions of the X axis, the Y axis and the Z axis is realized under the coordination of the driving component and the rolling parts on the bracket, so as to change the position of the nozzle plate 3 in a three-dimensional space.

It should be noted that, during the process of cooling the bushing 3, the support is detached from the bracket 21, and after cooling, the support is mounted on the bracket 21 to perform descending and ascending movements of the bushing 3, and the position of the bushing 3 is finely adjusted on the rolling members, so that the bushing 3 can be accurately mounted on and detached from the furnace body. The vertical surfaces of the first step 51 and the second step 52 face the two side walls of the bushing 3 to play a role in stopping and limiting, so that the bushing 3 is prevented from sliding down from the bracket when sliding on the rolling members.

Preferably, the bracket comprises a first mounting plate and a second mounting plate which are vertically extended and horizontally distributed oppositely, and a third mounting plate which horizontally connects the first mounting plate and the second mounting plate; the opposite surfaces of the first mounting plate and the second mounting plate are respectively provided with the box bottom of the first step 51 and the second step 52; and a bottom mounting plate 55 fixedly connecting the bottoms of the first mounting plate and the second mounting plate, preferably, the bottom mounting plate 55 is distributed in parallel with a third mounting plate, and the third mounting plate plays a role in strengthening the connection firmness of the first mounting plate and the second mounting plate.

As a modification of the transfer mechanism 2, if the space on site is sufficient, only the carriage 21 may be driven to perform the up-and-down movement without performing the horizontal telescopic movement.

In addition, as shown in fig. 1, the frame 1 is a movable frame, and the bottom of the frame is provided with a plurality of universal wheels 11, so that the position of the whole cooling device can be conveniently transferred.

Example 2

The present example provides a cooling system including the cooling device according to any one of the embodiments described in example 1.

The cooling system adopts the cooling device in the embodiment 1, so that the bushing 3 can be replaced after the bushing 3 is cooled in place in time by the cooling system.

Preferably, the cooling system further comprises a recovery device comprising a receiving container, the top opening of which is located below the cooling device for receiving the cooling solution falling from the nozzle plate 3, preferably in the shape of a funnel. In addition, a sealing ring is arranged between the inner wall of the top opening of the receiving container and the outer wall surface of the top of the furnace body, so that the cooling solution is prevented from splashing outside to cause the nearby electric leakage phenomenon or influence the normal production of the bushing plate 3 of the partition wall.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
