Description

Technical Field

[0001] This utility model relates to the field of aluminum molten metal interception technology, specifically to an aluminum molten metal flow channel interception structure. Background Technology

[0002] The flow interception structure of the aluminum molten flow channel is mainly used to control the flow of molten aluminum. During the aluminum processing, the molten aluminum needs to flow along a specific path and at a specific flow rate. The flow interception structure can precisely adjust the flow rate of the molten aluminum to ensure that it is stably and evenly delivered to subsequent processes or equipment. When it is necessary to stop the flow of molten aluminum, the flow interception structure can quickly close the channel to prevent the molten aluminum from continuing to flow, thus avoiding waste and safety hazards caused by the overflow of molten aluminum. It can also flexibly adjust the flow rate of molten aluminum when producing aluminum products of different specifications to adapt to diverse production needs, ensuring the smooth progress of aluminum processing and the stability of product quality.

[0003] Chinese patent CN217315839U discloses an aluminum water flow channel and an aluminum water interception device, which includes an aluminum water flow channel, a slide rail installed above the aluminum water flow channel, a fixing block installed in the middle of the slide rail, a rotating rod rotatably installed inside the fixing block, and lead screws symmetrically installed at both ends of the rotating rod. In this application, by setting various components such as slide rail, rotating rod, lead screws and limiting block, it is possible to quickly install the interception plate on the aluminum water flow channel. By setting multiple limiting slots, the user can install the interception plate in a suitable position according to the needs of use. The overall design is reasonable, and the installation of the interception device is relatively simple and convenient.

[0004] During the use of the aforementioned patented aluminum water flow channel aluminum water interception device, when the liquid flowing in the aluminum water flow channel is in a stable flow, the flow velocity drops to zero at the moment of interception, and all dynamic pressure is converted into static pressure. The liquid level near the interception point will be forced to rise due to the increased pressure, which can easily cause the flowing liquid to overflow the entire aluminum water flow channel at the moment of interception. Utility Model Content

[0005] The purpose of this utility model is to provide a flow interception structure for an aluminum water flow channel. An upper baffle covers the upper end of the intercepted liquid, and side baffles cover both sides of the intercepted liquid. After being guided by the upper baffle and the side baffles, the liquid is further restricted by the front baffle, which allows the splashed liquid to slowly flow back into the water flow channel, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flow interception structure for an aluminum water flow channel, comprising a support, with movable rails recessed on both sides of the front end of the support, and threaded rods vertically arranged inside the movable rails. Sliding blocks with threaded engagement are arranged on the outside of each of the two threaded rods, and the two sliding blocks are welded together by a rear baffle plate. An upper baffle plate is arranged at the upper end of the outer side of the rear baffle plate, and side baffle plates are arranged on both sides of the upper baffle plate. A front baffle plate is arranged at the front end between the two side baffle plates. The upper baffle plate and the side baffle plates facilitate the restriction and guidance of splashed liquid, thereby preventing liquid overflow.

[0007] Preferably, the front blind, side blind, upper blind and rear blind are welded and fixed in sequence. Welding and fixing can facilitate the movement of the front blind, side blind, upper blind and rear blind together.

[0008] Preferably, the front end of the rear baffle is provided with an inclined surface, which facilitates the flow of liquid.

[0009] Preferably, a limiting frame is welded to the lower end of the side baffle. After the threaded rod guides the flow, the limiting frame can be placed on the upper end of the water flow channel, which facilitates the installation of the sliding block.

[0010] Preferably, a telescopic rod is provided between the two supports, and a flow-blocking plate is provided at the lower end of the telescopic rod. The flow-blocking plate can be pushed and moved longitudinally downward by the extension of the telescopic rod.

[0011] Preferably, a shielding strip is welded to the lower end of the limiting frame, which can fill the gap between the intercepting plate and the water flow channel.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Before the intercepting plate is pushed and pressed into the water flow channel by the telescopic rod, the two sides of the front end of the intercepting plate are driven by the rotation of the threaded rod, so that the upper baffle covers the upper end of the intercepted liquid and the side baffle covers the two sides of the intercepted liquid. After being guided by the upper baffle and the side baffle, the liquid is further restricted by the front baffle, so that the splashed liquid can slowly flow back into the water flow channel. Before interception, the possible rise in liquid level is limited, which effectively avoids the liquid level rise caused by all dynamic pressure being converted into static pressure at the moment of interception, and prevents the liquid from overflowing from the water flow channel.

[0021] The present invention will be further described below with reference to specific embodiments.

[0022] like Figure 1 and Figure 2 As shown, the interception structure of an aluminum water flow channel in this embodiment includes a bracket 1, which is installed on the upper end of the water flow channel 12. The entire interception structure can be erected on the upper end of the water flow channel 12 through the bracket 1.

[0023] To prevent liquid overflow during interception, movable rails 5 are recessed on both sides of the front end of the support 1. Threaded rods 6 are vertically installed inside the movable rails 5. Sliding blocks 7 are installed on the outside of both threaded rods 6, and the sliding blocks 7 are threadedly engaged with the outer wall of the threaded rods 6. During interception, the rotation of the threaded rods 6 can longitudinally push the sliding blocks 7, thereby completing the interception.

[0024] Furthermore, the two sliding blocks 7 are welded and fixed together by the rear baffle plate 13. After being connected by the rear baffle plate 13, the sliding blocks 7 can be driven to move longitudinally in unison after being driven by the threaded rod 6. The front end of the rear baffle plate 13 is provided with an inclined surface 14. The inclination of the inclined surface 14 can facilitate the flow of liquid and facilitate the flow of liquid that is about to overflow back into the water flow tank 12.

[0025] In addition, such as Figure 3 , Figure 4 and Figure 5As shown, an upper baffle 8 is provided at the upper end of the outer side of the rear baffle 13, and side baffles 9 are provided on both sides of the upper baffle 8. A front baffle 10 is provided at the front end between the two side baffles 9. The front baffle 10, side baffles 9, upper baffle 8 and rear baffle 13 are welded and fixed in sequence. After being driven by the rear baffle 13, the front baffle 10, side baffles 9 and upper baffle 8 can be moved vertically downward together in sync.

[0026] The front baffle 10 can handle the backflow of liquid at the front, while the side baffle 9 can handle the backflow of liquid on both sides.

[0027] To facilitate the installation of the rear baffle 13, a limiting frame 16 is provided at the lower end of the side baffle 9, and the limiting frame 16 is welded and fixed to the lower end of the side baffle 9. The outer side of the limiting frame 16 is connected to the upper end of the water flow channel 12 through a slot. After the sliding block 7 moves longitudinally downward, the limiting frame 16 can be stably installed on the upper end of the water flow channel 12, thereby improving stability.

[0028] In order to intercept the liquid inside the water flow tank 12, a telescopic rod 2 is provided between the two supports 1. A flow intercepting plate 4 is provided at the lower end of the telescopic rod 2, and the upper end of the flow intercepting plate 4 is fixedly connected to the lower end of the telescopic rod 2 by bolts. The extension of the telescopic rod 2 can push and make the flow intercepting plate 4 move vertically downward, thereby completing the interception of the water flow tank 12.

[0029] In order to block the gap between the two sides of the intercepting plate 4 and the water flow channel 12 in advance, a shielding strip 11 is provided at the lower end of the limiting frame 16, and the shielding strip 11 is welded and fixed to the lower end of the limiting frame 16. The shielding strip 11 can move longitudinally downward together with the limiting frame 16, so as to fill and cover the gap between the intercepting plate 4 and the water flow channel 12 in advance.

[0030] To improve the stability of the baffle plate 4 during longitudinal movement, such as Figure 6 As shown, both sides of the cutoff plate 4 are recessed with limiting holes 15. Each of the two limiting holes 15 is provided with a limiting rod 3 at its upper end. The limiting rod 3 is welded and fixed to the lower end of the bracket 1. After the cutoff plate 4 is retracted by the telescopic rod 2, the limiting rod 3 can slide into the limiting hole 15.

[0031] Working principle: When the device is used to intercept the liquid inside the water flow tank 12, the threaded rod 6 corresponds to the start of the motor. After being restricted by the movable rail 5, the sliding block 7 changes from rotational motion to longitudinal linear motion. The sliding block 7 drives the upper baffle plate 8 and the baffle strip 11 to move longitudinally into the water flow tank 12. The extension of the telescopic rod 2 pushes the intercepting plate 4, which covers the liquid flow area inside the water flow tank 12. During the process of the intercepting plate 4 restricting the liquid flow, the rising liquid level near the interception point is blocked and guided by the rear baffle plate 13, the upward-rising liquid is guided by the upper baffle plate 8 and the front baffle plate 10, and the liquid rising to both sides is guided by the side baffle plate 9. The restriction by the side baffle plate 9 and the upper baffle plate 8 can prevent the liquid from overflowing and allow the overflowing liquid to flow back into the baffle strip 11.
