Description

Technical Field

[0001] This application relates to the technical field of zinc alloy filter residue cooling devices, and in particular to a zinc alloy surface pneumatic cooling control negative pressure filter residue device. Background Technology

[0002] Zinc alloys are zinc-based alloys with the addition of other elements. They possess advantages such as low melting point, good fluidity, ease of welding and plastic processing, good corrosion resistance in the atmosphere, and easy recycling and remelting of scrap. In the forming process of zinc alloys, molten material is first added to the forming cavity, then cooled, and finally the cooled, formed strip of zinc alloy is transported away.

[0003] Existing zinc alloy cooling equipment consists of a casing, cooling spray pipes, and other structures. However, some problems exist in the cooling spray process, such as uneven spraying. Furthermore, molten alloy exposed to air oxidizes, forming slag. This slag needs to be removed from the surface of the molten alloy in the previous cooling process (but not too early; a thin layer of slag on the surface of the molten liquid helps prevent further oxidation in the tank). Current slag removal methods rely on manual or robotic processes, which is labor-intensive and requires significant investment in production. Therefore, this application proposes a pneumatically cooled, controlled negative pressure slag removal device for zinc alloy surfaces. Summary of the Invention

A negative pressure mechanism is provided on one side of the mist collection hood to control the growth rate of zinc alloy grains and refine the grains; reduce surface scarring during zinc alloy ingot casting and improve the surface quality of zinc alloy ingots.

[0006] On the other side of the mist collection hood is an adsorption shell, and the arc surface of the adsorption shell is provided with a number of negative pressure adsorption holes. On one side of the negative pressure mechanism is a negative pressure adsorption auxiliary mechanism for controlling the intermittent negative pressure of the adsorption shell. The negative pressure adsorption auxiliary mechanism includes an air guide pipe controlled by the negative pressure mechanism, and also includes an air hood connected to the adsorption shell. The air hood and the air guide pipe are intermittently and tightly connected through an air supply pipe, and negative pressure is generated during the contact phase.

[0007] It also includes a pressure relief auxiliary mechanism for controlling the pressure relief of the adsorption shell.

[0008] Preferably, the cooling component includes a liquid pipe and a gas pipe, the output ends of which are provided with spray heads, and also includes a mist-dispersing cover placed on the outside of the spray heads.

[0009] Preferably, the bottom end of the mist hood is provided with a plurality of cooling mist exhaust ports, and the diameter of the cooling mist exhaust ports is arranged in a manner that is larger on the outside and smaller on the inside.

[0010] Preferably, the negative pressure mechanism includes a cover and a negative pressure fan disposed inside the cover. The inner wall of the cover is provided with a negative pressure shield, the opening of which is located at the negative pressure end, and the air guide pipe is connected to the negative pressure shield.

[0011] Preferably, an annular contact plate is fixedly sleeved on the outer wall of the bottom end of the gas pipe, a limit ring is fixedly connected to the inner wall of the upper end of the gas hood, and a movable ring is slidably connected to the inner wall of the gas hood. The movable ring and the limit ring are elastically connected by an elastic rod.

[0012] Preferably, the inner walls of the limiting ring and the movable ring maintain a distance from the outer wall of the gas transmission pipe, the outer diameter of the annular contact plate is larger than the inner diameter of the movable ring, and a sealing ring is fixedly connected to the upper end of the annular contact plate.

[0013] Preferably, one side of the mist collecting hood is connected to an inverted U-shaped frame via several support rods, and the adsorption shell is slidably disposed inside the inverted U-shaped frame via a connecting rod. An electric telescopic rod for driving the adsorption shell to rise and fall is installed on the upper inner wall of the inverted U-shaped frame.

[0014] Preferably, the pressure relief auxiliary mechanism includes a piston cylinder communicating with the adsorption shell. The bottom end of the piston cylinder is provided with an air inlet plate, and the air inlet plate is provided with an air inlet. A one-way valve A is provided on the air inlet to control the gas in the adsorption shell to only enter and not exit. The lower end side wall of the piston cylinder is connected to a pressure balance pipe, and a one-way valve B is provided on the pressure balance pipe to control the gas in the piston cylinder to only enter and not exit.

[0015] A push-pull rod is fixedly connected to the upper inner wall of the inverted U-shaped frame, and a piston is connected to the bottom end of the push-pull rod.

[0016] Preferably, the piston cylinder and the inverted U-shaped frame have a gap, and the piston can be detached from the piston cylinder.

[0018] Compared with the prior art, this application has the following beneficial technical effects:

[0019] This application provides a mist-uniforming hood inside the mist-collecting hood, with several cooling mist outlets at the bottom of the mist-uniforming hood. The diameter of the cooling mist outlets is arranged in a manner that is larger on the outside and smaller on the inside, which can expand the discharge area of ​​the cooling mist, so that the liquid in the forming tank is cooled evenly and the cooling effect is guaranteed. By setting a negative pressure mechanism on one side of the mist-collecting hood, the growth rate of zinc alloy grains can be controlled, the grains can be refined, the surface scars during zinc alloy ingot casting can be reduced, and the surface quality of zinc alloy ingots can be improved.

[0020] By setting up an adsorption shell, the negative pressure and pressure relief state of the adsorption shell are controlled by the negative pressure adsorption auxiliary mechanism and the inverted U-shaped frame under the action of the negative pressure fan, thereby completing the adsorption and removal of the scum film, saving manpower and costs. Moreover, the adsorption shell is located at the feeding end of the mist collection hood, so that the forming tank after removing the scum film can enter the mist collection hood in the next step, avoiding the molten liquid from contacting the air again to oxidize and generate scum film.

[0039] Example

[0040] like Figure 1-8As shown, this application proposes a negative pressure filter device for pneumatic cooling control of zinc alloy surfaces, comprising a mist collecting hood 2 and a cooling component disposed within the mist collecting hood 2. The cooling component includes a liquid pipe 4 and an air pipe 5. The liquid pipe 4 is connected to an external coolant supply device, and the air pipe 5 is connected to an external pneumatic device. Spray heads are provided at the output ends of the liquid pipe 4 and the air pipe 5. A mounting plate is fixedly connected inside the mist collecting hood 2, and the spray heads are fixedly mounted on the bottom end of the mounting plate. The device also includes a uniform mist hood 6 fixedly covering the outside of the spray heads. The bottom end of the uniform mist hood 6 has several cooling mist exhaust ports 61, and the diameter of the cooling mist exhaust ports 61 is arranged in a manner that is larger on the outside and smaller on the inside, which can expand the discharge area of ​​the cooling mist and make the liquid in the forming tank uniformly cooled. A negative pressure mechanism 3 is provided on one side of the mist collecting hood 2 to absorb excess atomized liquid, control the growth rate of zinc alloy grains, refine the grains, reduce surface scarring during zinc alloy ingot casting, and improve the surface quality of zinc alloy ingots.

[0041] Furthermore, an adsorption shell 10 is provided on the other side of the mist collecting hood 2. The adsorption shell 10 is semi-cylindrical with its arc-shaped surface facing downwards. The arc-shaped surface is smooth, making it easy for the scum film to detach under negative pressure. The arc-shaped surface of the adsorption shell 10 has several negative pressure adsorption holes 101. The diameter of the negative pressure adsorption holes 101 is larger on the outside and smaller on the inside, and a mesh plate is embedded in the inner wall of its outer end to prevent the scum film from being sucked into the adsorption shell 10. The spacing between adjacent negative pressure adsorption holes 101 is set according to specific conditions to ensure that the negative pressure state inside the adsorption shell 10 can smoothly absorb the scum film. When the pressure is released, the scum film can be blown off smoothly. A negative pressure adsorption auxiliary mechanism 7 is provided on one side of the negative pressure mechanism 3 to control the intermittent negative pressure of the adsorption shell 10. This ensures that the adsorption shell 10 is in a negative pressure adsorption state before and during contact with the scum film. After the adsorption shell 10 rises to a certain height, the negative pressure adsorption auxiliary mechanism 7 begins to release pressure. The device includes a gas guide pipe 701 controlled by the negative pressure mechanism 3, which passes through the mist collection hood 2 and is fixedly connected to it. It also includes a gas hood 706 connected to the adsorption housing 10. The gas hood 706 and the gas guide pipe 701 are intermittently and sealed in communication through a gas supply pipe 703. Before the adsorption housing 10 comes into contact with the scum film, the gas hood 706 and the gas guide pipe 701 are sealed in communication through the gas supply pipe 703, so that the adsorption housing 10 is kept under negative pressure, which can smoothly adsorb the scum film onto the outer wall of the adsorption housing 10. One side of the mist collecting hood 2 is fixedly connected to an inverted U-shaped frame 8 by several support rods 14. The air hood 706 is slidably connected to the inverted U-shaped frame 8. The adsorption shell 10 is slidably set inside the inverted U-shaped frame 8 by connecting rods 9. Strip plates are slidably connected to the inner walls of both sides of the inverted U-shaped frame 8. Two connecting rods 9 are fixedly connected to the inner walls of the two strip plates respectively. An electric telescopic rod 13 for driving the adsorption shell 10 to rise and fall is installed on the upper inner wall of the inverted U-shaped frame 8. The electric telescopic rod 13 is vertically fixedly installed on the inner wall of the inverted U-shaped frame 8. The telescopic end of the electric telescopic rod 13 is fixedly connected to the adsorption shell 10. Multiple electric telescopic rods 13 can be set, and there is no limitation. If one is set, it will be set in the middle part of the adsorption shell 10 in order to control the rise and fall of the adsorption shell 10 in a balanced manner.

[0042] Specifically, the negative pressure mechanism 3 includes a cover and a negative pressure fan installed inside the cover. The cover is mounted on the upper end of the conveying frame 1 via a support base. The negative pressure fan is mounted inside the cover via a motor mount (not shown in the figure due to perspective). A negative pressure hood 702 is fixedly connected to the inner wall of the cover. The opening of the negative pressure hood 702 is located at the negative pressure end. The air guide pipe 701 communicates with the negative pressure hood 702. An annular contact plate 707 is fixedly sleeved on the outer wall of the bottom end of the air supply pipe 703. The outer diameter of the annular contact plate 707 is smaller than the inner diameter of the air hood 706. A limit ring 709 is fixedly connected to the inner wall of the upper end of the air hood 706, and a movable ring 705 is slidably connected to the inner wall of the air hood 706. The movable ring 705 is connected to... The limiting rings 709 are elastically connected by an elastic rod 708. The elastic rod 708 is divided into a connecting cylinder and a sliding rod. A spring fixedly connected to the sliding rod is provided inside the connecting cylinder. The connecting cylinder is fixedly connected to the movable ring 705, and the sliding rod is fixedly connected to the limiting rings 709. The structure of the elastic rod 708 here is existing technology and will not be described in detail here. The inner walls of the limiting rings 709 and the movable ring 705 maintain a distance from the outer wall of the air supply pipe 703. The outer diameter of the annular contact plate 707 is larger than the inner diameter of the movable ring 705, and a sealing ring is fixedly connected to the upper end of the annular contact plate 707. When the annular contact plate 707 contacts the movable ring 705, the negative pressure fan keeps the adsorption housing 10 in a negative pressure state.

[0043] It also includes a pressure relief auxiliary mechanism 11 for controlling the pressure relief of the adsorption housing 10. The pressure relief auxiliary mechanism 11 includes a piston cylinder 111 connected to the adsorption housing 10. The bottom end of the piston cylinder 111 is provided with an air inlet plate 112. The air inlet plate 112 has an air inlet 113. The air inlet 113 is provided with a one-way valve A to control the gas in the adsorption housing 10 to only enter and not exit. The lower end side wall of the piston cylinder 111 is connected to a pressure balance pipe 116. The pressure balance pipe 116 is provided with a one-way valve B to control the gas in the piston cylinder 111 to only enter and not exit. The upper inner wall of the inverted U-shaped frame 8 is fixedly connected to a push-pull rod 115. The bottom end of the push-pull rod 115 is connected to a piston 114. By providing a one-way valve B on the pressure balance pipe 116, the piston 114 can slide smoothly upward. The piston cylinder 111 and the inverted U-shaped frame 8 are spaced apart. The piston 114 can be detached from the piston cylinder 111. The system also includes a conveying frame 1, which conveys the forming trough through a conveying mechanism. A collection trough 12 is slidably connected to the upper end of the conveying frame 1. The collection trough 12 is connected to an external driving component. The driving component and the upper edge of the conveying frame 1 are parallel. Sliding grooves are provided on both upper edges of the conveying frame 1. Two driving components are respectively positioned within the two sliding grooves, and the telescopic ends of the driving components are fixedly connected to support blocks that are slidably connected to the sliding grooves. The collection trough 12 can be detachably snapped onto the upper ends of the two support blocks (this snapping is a conventional snapping method), facilitating the removal of the collection trough 12 to clean the internal scum. The driving component can be a hydraulic telescopic cylinder. Both the driving component and the electric telescopic rod 13 are electrically connected to an external controller. The driving speed and frequency of the driving component and the electric telescopic rod 13 are set according to the scenario. When the adsorption housing 10 moves downward, the piston 114 moves to the upper end of the piston cylinder 111. After the piston 114 disengages from the piston cylinder 111, the negative pressure state inside the adsorption housing 10 is maintained by the negative pressure adsorption auxiliary mechanism 7. A one-way valve A is provided on the air inlet 113 so that even if the piston 114 disengages from the piston cylinder 111, the gas inside the adsorption housing 10 will not leak out through the air inlet 113. After the scum film is adsorbed, the adsorption housing 10 is moved upward by the electric telescopic rod 13. In the initial stage of the upward movement of the adsorption housing 10, the elastic rod 708 has a buffer rebound process, so that the annular contact plate 707 and the movable ring 705 are continuously in contact for a period of time. At this time, the piston 114 has not entered the interior of the piston cylinder 111. Until the collection tank 12 slides to the bottom of the adsorption housing 10, the annular contact plate 707 disengages from the movable ring 705, so that the negative pressure adsorption auxiliary mechanism 7 stops controlling the negative pressure state in the adsorption housing 10. The piston 114 enters the piston cylinder 111 and squeezes the gas inside the piston cylinder 111 into the adsorption housing 10, entering the pressure relief stage. It is worth noting that the pressure relief auxiliary mechanism 11 can be set in multiple sets, and the gas cover 706 and the internal auxiliary structure can also be set in multiple sets to provide sufficient negative pressure and pressure relief.

[0044] In practice: Cooling components are installed inside the mist collecting hood 2. The coolant in the liquid pipe 4 is atomized by gas in the air pipe 5 and enters the uniform mist hood 6. It is then evenly sprayed onto the zinc alloy through several cooling exhaust ports 61, causing the zinc alloy to cool and solidify. The negative pressure fan inside the negative pressure mechanism 3 operates, sucking away excess atomized coolant, controlling the growth rate of zinc alloy grains, refining the grains, and reducing surface scarring during zinc alloy ingot casting, thereby improving the surface quality of the zinc alloy ingot. The atomized coolant sucked into the hood is discharged through pipes on the side wall of the shell and collected centrally. A conveying mechanism is installed inside the conveying frame 1. The conveying mechanism can be a chain conveyor or a belt conveyor, which is existing technology and will not be described in detail here. The conveying mechanism transports the molding tank filled with molten liquid towards the mist collection hood 2. When one of the molding tanks is about to be transported to the bottom of the adsorption shell 10, the electric telescopic rod 13 is activated. Its telescopic end extends and drives the adsorption shell 10 to move downward and contact the thin film on the upper surface of the liquid inside the molding tank. At this time, the annular contact plate 707 abuts against the lower surface of the movable ring 705. The adsorption shell 10, the gas supply pipe 703, and the gas guide pipe 701 are sealed and connected. Since the open end of the negative pressure hood 702 is installed at the negative pressure end, the suction air inside the adsorption shell 10 is sucked away, making the adsorption shell 10 a negative pressure state. This causes the scum film to be adsorbed on the outside of the adsorption shell 10. After the adsorption is completed, the telescopic end of the electric telescopic rod 13 retracts and drives the adsorption shell 10 to move upward. At this time, the external driving component drives the collection tank 12 to slide quickly to the bottom of the adsorption shell 10. When the adsorption shell 10 moves upward... After rising to a certain height, the annular contact plate 707 moves away from the movable ring 705, and the negative pressure state inside the adsorption housing 10 will end. (Because an elastic rod 708 is provided between the limiting ring 709 and the movable ring 705, the annular contact plate 707 and the movable ring 705 have a process of contact and movement, so that the adsorption housing 10 will maintain a negative pressure state during the rising process, preventing the scum film adsorbed on the outer surface of the adsorption housing 10 from detaching before the collection tank 12 moves to the bottom of the adsorption housing 10). At this time, the piston 114 extends into the interior of the piston cylinder 111, and the gas inside the piston cylinder 111 is squeezed into the interior of the adsorption housing 10 through the air inlet 113. The interior of the adsorption housing 10 is in a depressurized state, and the gas inside the adsorption housing 10 is pushed outward through several negative pressure adsorption holes 101, blowing off the adsorbed scum film. The above steps are repeated to achieve continuous removal of scum film. It should be noted that there is a certain distance between two adjacent forming tanks to ensure that the scum film removal operation can be completed smoothly.
