Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal ingot casting, and more specifically to an immersion type quantitative casting device. Background Art
[0002] The molten metal that has completed the refining process must be cast into a metal ingot of a specified shape and weight in a mold before it can be sold as a metal product. In the traditional casting process, a filter is often only set up to separate the slag, and there is no sedimentation or slag isolation process. During the casting process, a large amount of oxidized slag is produced, and some metal slag with higher density will be carried by the molten metal and hit the filter during equipment vibration or slag removal. Some oxidized slag and metal slag with higher density will enter the mold with the casting liquid, affecting the product quality and causing a large number of cast metal ingot products to be unqualified.
[0003] In the conventional casting process, a large amount of oxide slag is produced during the casting process when the molten metal is injected into the mold due to the large area of contact with the air and the long process. Much of the oxide slag is enriched on the side walls and edges of the metal ingot along with the molten metal. The molten metal flushes the casting equipment, and some metal slag with higher density also enters the mold along with the molten metal and settles at the bottom of the metal ingot.
[0004] Therefore, how to provide a quantitative casting device that can effectively remove the included oxide slag during the casting process of the molten metal and improve the qualified rate of the metal ingot products is a problem that the technicians in this field need to solve urgently. Utility Model Content
[0005] In view of this, the utility model provides an immersion quantitative casting device, which can avoid the problem that fine oxide slag and high-density metal slag in the metal melt are difficult to remove during the ingot wiping process, resulting in unqualified metal ingot products, thereby improving the qualified rate of metal ingot products.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] An immersion quantitative casting device comprises a traveling support, a tin mold, a detection component, a quantitative pump, a sludge box, a pot-shaped casting device and a driving component;
[0008] The tin mold is located in the traveling support and is slidably connected to the traveling support in the height direction, and the detection component is fixed on one side of the traveling support to detect the empty or full signal in the tin mold;

[0010] The beneficial effect of the above technical solution is that the metering pump quantitatively extracts the molten metal in the insulated crucible, the molten metal enters the slag box through the pipeline to precipitate and filter the metal slag, and the filtered molten metal enters the pot-type caster, and the pot-type caster is controlled by the driving component to tilt it. The tilting of the pot-type caster can make the molten metal pour into the tin mold; the detection component detects the empty or full signal in the tin mold, and when the empty signal is detected, the tin mold moves to the bottom of the corresponding pot-type caster spout. After the casting is full, the tin mold is pushed forward to cast the next group of tin molds.
[0011] Preferably, the sediment box comprises a box body, a partition, a filter screen and a liquid outlet pipe; the top of the box body is open, and the partition and the filter screen are arranged vertically and parallelly along the length direction of the box body in sequence to divide the inner cavity of the box body into a first sedimentation chamber, a second sedimentation chamber and a liquid outlet chamber; one end of the liquid outlet pipe is fixed to the side wall of the box body away from the filter screen and connected to the liquid outlet chamber, and the other end is bent downward by 90° and penetrates into the liquid inlet of the pot-shaped caster;

[0013] The beneficial effect of the above technical solution is that the sludge box is a two-stage sedimentation box. The molten metal enters the sludge box and first passes through the partition in the first sedimentation chamber for the first coarse filtration and sedimentation. Then, the molten metal after the first sedimentation enters the second sedimentation chamber and is filtered out through the filter net to remove a large amount of metal oxide slag and black slag. Finally, the molten metal that has completed the second filtration enters the pot-type caster using the height difference.
[0014] Preferably, the pot-shaped casting device comprises a pot body, a liquid inlet box, a hollow pot handle and a pot spout. The liquid inlet box is fixed on the side wall of the pot body, the two ends of the hollow pot handle are respectively fixed to the bottom wall of the liquid inlet box and the side wall of the pot body relative to the liquid inlet box, and its inner cavity is connected to the inner cavity of the liquid inlet box and the pot body, one end of the pot spout is fixed to the side wall of the pot body away from the liquid inlet box, and the other end is located in the walking bracket, and the end of the liquid outlet pipe away from the box body is deep into the liquid inlet box. The molten metal after secondary sedimentation and filtration in the sediment box first enters the liquid inlet box, and the molten metal in the liquid inlet box enters the pot body through the hollow handle. The pot-shaped casting device is provided with two accommodating spaces, which can realize the third filtration of the molten metal.

[0017] The beneficial effect of the above technical solution is that the steel wire rope connecting the driving cylinder and the spout is always in a taut state. After the driving cylinder is started, the extension and retraction of its piston rod can make the pot-shaped caster rotate around the pin shaft. The setting of the liquid inlet box and the pot body can make the pot-shaped caster tilt toward the spout when the piston rod is extended to complete the pouring of the molten liquid.
[0018] Preferably, a mounting plate is fixed to the ends of the top surfaces of the two horizontal rods away from the vertical rods, and the driving cylinder is fixed to the top surface of the mounting plate. The driving cylinder is fixed by the fixing plate.

The end of the steel wire away from the driving cylinder can be wound around the ear hole of the pin plate and the steel wire and the spout can be locked by a buckle, ensuring that the steel wire is always connected to the spout after the driving cylinder is started, so as to achieve the effect of pouring molten metal from the pot-shaped caster.
[0020] Preferably, the walking bracket includes vertical poles and horizontal poles, the number of the vertical poles is four and they form the legs of the walking bracket, the bottom ends of the four vertical poles are rotatably connected with a rotating wheel; the number of the horizontal poles is four, the four horizontal poles are connected end to end to form a square frame and are fixed to the top ends of the four vertical poles.

[0021] Preferably, it also includes a pulley, which is located between the two horizontal rods and is rotatably connected to the top surface of the cross bar of the square frame close to the pot-shaped pouring device, and the steel wire rope passes through the pulley from the driving cylinder and is fixed to the pin plate.

When the liquid level in the pot-shaped casting device is too high, the molten metal can flow back to the heat-insulating crucible through the overflow hole and the reflux pipe, thereby preventing the waste of the molten metal.
[0023] Preferably, the detection assembly includes a detection cylinder and a detection probe. The detection cylinder is fixed on a side of the traveling support away from the pot-shaped caster. One end of the detection probe is fixed to the driving end of the detection cylinder, and the other end is inserted into the traveling support and can abut against the top surface of the tin mold. The signal output end of the detection cylinder is respectively connected to the quantitative pump and the signal receiving end of the driving assembly, and the signal input end is electrically connected to the control system of the quantitative casting device. After the detection probe detects the empty or full signal in the tin mold, it will simultaneously feedback the quantitative pump and the driving cylinder. When the control system of the quantitative casting device is in the automatic casting mode, the probe detects that the tin mold signal is empty, the driving cylinder extends, the spout of the pot-shaped caster is lowered for casting, and the quantitative pump is started for liquid supply; the probe detects that the tin mold signal is full, the driving cylinder retracts, the spout of the pot-shaped caster is raised to stop casting, and the quantitative pump stops supplying liquid.

The molten metal transported from the quantitative pump can effectively separate the slag and slag with high density in the molten metal after passing through the slag box and the pot-shaped caster, so that the slag content in the casted molten metal is greatly reduced, reducing the workload of subsequent wiping; after the sedimentation effect of the slag box and the pot-shaped caster, the appearance of high-density metal slag at the bottom of the metal ingot can be further avoided; the oxidized slag on the surface of the slag box and the pot-shaped caster can protect the molten metal from continuing to contact with the air and being oxidized, thereby reducing the amount of oxidized slag generated.

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0038] See attached Figures 1 to 3The embodiment of the utility model discloses an immersion quantitative casting device, including a walking support 4, a tin mold 6, a detection component 7, a quantitative pump 1, a sludge box 2, a pot-shaped casting device 3 and a driving component 5;
[0039] The tin mold 6 is located in the traveling bracket 4 and is slidably connected with the traveling bracket 4 in the height direction. The detection component 7 is fixed on one side of the traveling bracket 4 to detect the empty or full signal in the tin mold 6;
[0040] The inlet end of the metering pump 1 is connected to the insulated crucible to extract the molten metal therein, and the liquid inlet of the slag box 2 is connected to the discharge port of the metering pump 1 through a pipeline; the liquid inlet of the pot-shaped caster 3 is connected to the liquid outlet of the slag box 2, and its liquid outlet is located in the walking bracket 4, and the driving component 5 is connected to the pot-shaped caster 3 to tilt it to cast the molten metal into the tin mold 6.
[0041] In this embodiment, the sediment box 2 includes a box body 21, a partition 22, a filter screen 23 and a liquid outlet pipe 24; the top of the box body 21 is open, and the partition 22 and the filter screen 23 are arranged in parallel and vertically along the length direction of the box body 21 to divide the inner cavity of the box body 21 into a first sedimentation chamber 25, a second sedimentation chamber 26 and a liquid outlet chamber 27; one end of the liquid outlet pipe 24 is fixed to the side wall of the box body 21 away from the filter screen 23 and connected to the liquid outlet chamber 27, and the other end is bent downward by 90 degrees and penetrates into the liquid inlet of the pot-shaped casting device 3;
[0042] The top opening of the box body 21 corresponding to the first sedimentation chamber 25 is connected to the discharge port of the metering pump 1 through a pipeline; the height of the partition plate 22 is smaller than the height of the box body 21 , and the height of the filter screen 23 is the same as the height of the box body 21 .
[0043] like Figure 2 As shown, the sludge box is a two-stage sedimentation box, the partition height is 300-350mm and is smaller than the height of the sludge box. The molten metal entering the first sedimentation chamber enters the second sedimentation chamber through the opening between the top of the partition and the box body after coarse filtration and sedimentation. The molten metal in the second sedimentation chamber can filter out most of the oxide slag or black slag through the filter screen and enter the liquid outlet chamber. The end of the liquid outlet pipe close to the box body is 100-150mm away from the bottom of the box body. The height difference is used to allow the molten metal to enter the pot-type caster. The end of the liquid outlet pipe away from the box body is bent downward at 90° to prevent the reflux of the molten metal.
[0044] In this embodiment, the pot-shaped casting device 3 includes a pot body 32, a liquid inlet box 31, a hollow pot handle 33 and a pot spout 35. The liquid inlet box 31 is fixed on the side wall of the pot body 32. The two ends of the hollow pot handle 33 are respectively fixed to the bottom wall of the liquid inlet box 31 and the side wall of the liquid inlet box 31 relative to the pot body 32, and its inner cavity is connected with the inner cavity of the liquid inlet box 31 and the pot body 32. One end of the pot spout 35 is fixed on the side wall of the pot body 32 away from the liquid inlet box 31, and the other end is located in the walking bracket 4. The end of the liquid outlet pipe 24 away from the box body 21 penetrates into the liquid inlet box 31.
[0045] like Figure 3 As shown, the pot-shaped caster has two inner cavities, one is formed by the liquid inlet box, and the other is formed by the pot body. The inner cavity between the liquid inlet box and the pot body is connected through a hollow pot handle. The downward bent part of the liquid outlet pipe penetrates into the liquid inlet box. The molten metal entering the liquid inlet box flows into the pot body through the hollow pot handle, and the molten metal can be precipitated for the third time.
[0046] The pot-shaped pouring device is a device for temporarily storing high-quality casting molten metal. The spout is located 100 to 150 mm from the bottom of the arc-shaped pouring device, which can further isolate the oxide slag and slag with higher density in the metal melt.
[0047] In order to further optimize the above technical solution, the driving assembly 5 includes a fixing frame 54, a driving cylinder 53 and a steel wire rope 52. Two corresponding pin holes 34 are opened on the two side walls of the vertical kettle body 32 of the liquid inlet box 31. The fixing frame 54 is composed of a vertical rod and a horizontal rod to form an inverted L-shaped frame. There are two fixing frames 54 and they are symmetrically arranged along the two sides of the liquid inlet box 31.
[0048] A through hole connected to the pin hole 34 is opened on the rod wall of the vertical rod, and the pin shaft passes through the through hole and the pin hole 34 in sequence so that the two vertical rods are hinged to the liquid inlet box 31, the bottom surface of the horizontal rod is fixed to the top surface of the walking bracket 4, the driving cylinder 53 is fixed to the top surface of the horizontal rod, one end of the wire rope 52 is fixed to the piston rod of the driving cylinder 53, and the other end is fixed to the outer wall of the spout 35.
[0049] A steel wire rope is used to connect the piston rod of the driving cylinder and the spout. Since the pin shaft is arranged at the liquid inlet box, the pot-shaped caster has an eccentric structure. When the piston rod is not extended, the steel wire rope is taut. The pot-shaped caster is pulled horizontally by the steel wire rope. When the piston rod is extended, the steel wire rope will be relaxed. After the steel wire rope is relaxed, the pot-shaped caster will tilt back to the spout side due to the eccentric effect. The tilted spout can pour the molten metal into the tin mold.
[0050] In order to further optimize the above technical solution and ensure reliable fixation of the driving cylinder, a mounting plate 55 is fixed to the ends of the top surfaces of the two horizontal rods away from the vertical rods, and a driving cylinder 53 is fixed to the top surface of the mounting plate 55 .
[0051] In order to further optimize the above technical solution, ensure the reliable connection between the steel wire rope and the pot-shaped casting device, and prevent the connection between the steel wire rope and the spout from being disconnected during the extension and retraction of the piston rod, a pin plate 36 is fixed to the outer wall of the spout 35, and the end of the steel wire rope 52 away from the driving cylinder 53 is fixed to the pin plate 36.
[0052] In this embodiment, the walking frame 4 includes vertical poles 41 and horizontal poles 43. There are four vertical poles 41 and they form the legs of the walking frame 4. The bottom ends of the four vertical poles 41 are rotatably connected to the rotating wheels 42. There are four horizontal poles 43 and they are connected end to end to form a square frame and are fixed to the top ends of the four vertical poles 41.
[0053] There are multiple groups of tin molds, which are placed side by side on a conveyor belt (not shown in the figure). The conveyor belt runs through the interior of the traveling bracket. The tin molds slide along the traveling bracket through the transmission belt. Since the bent part of the liquid outlet pipe penetrates into the liquid inlet box, the distance between the outer wall of the liquid outlet pipe and the two opposite inner walls of the liquid inlet box is the distance for the traveling bracket to reciprocate.
[0054] There is a relative speed difference between the walking speed of the walking bracket and the transmission speed of the conveyor belt. The position of the walking bracket is limited (the distance between the liquid outlet pipe and the inner wall of the liquid inlet box), and the conveyor belt continues to transport.
[0055] In some other specific embodiments, a pulley 51 is further included, the pulley 51 is located between the two horizontal rods and is rotatably connected to the top surface of the crossbar 43 of the square frame close to the pot-shaped pouring device 3, and the steel wire rope 52 self-driving cylinder 53 bypasses the pulley 51 and is fixed to the pin plate (36). The sliding can ensure that the steel wire rope slides up and down smoothly, and at the same time, the pulley makes the line shape of the steel wire rope into a 7-shaped shape, avoiding the crossbar, and ensuring the effectiveness of the steel wire rope.
[0056] In order to further optimize the above technical solution and prevent the waste of molten metal, a reflux pipe 37 is also included. An overflow hole 38 is opened on the side wall of the pot body 32. One end of the reflux pipe 37 is fixed to the peripheral wall of the pot body 32 relative to the overflow hole 38 and is connected to the inner cavity of the pot-shaped caster 3, and the other end is deep into the insulating crucible.
[0057] In order to further optimize the above technical solution, the detection assembly 7 includes a detection cylinder 72 and a detection probe 71. The detection cylinder 72 is fixed on the side of the traveling bracket 4 away from the pot-shaped casting device 3. One end of the detection probe 71 is fixed to the driving end of the detection cylinder 72, and the other end is deep into the traveling bracket 4 and can abut against the top surface of the tin mold 6. The signal output end of the detection cylinder 72 is respectively connected to the quantitative pump 1 and the signal receiving end of the driving assembly 5, and the signal input end is electrically connected to the control system of the quantitative casting device. The detection probe can detect the empty or full signal of the molten metal in the tin mold through the sensor.
[0058] In this embodiment, the driving assembly is fixed on the cross bar of the traveling frame, and the driving assembly suspends the pot-shaped caster through a steel wire rope. The pot-shaped caster, the driving assembly and the traveling frame form an integrated structure. The traveling trolley drives the pot-shaped caster to move in a small range during the walking process to ensure the fullness of the molten metal casting in the tin mold. The moving range of the pot-shaped caster, the driving assembly and the traveling frame forming an integrated structure is the distance between the liquid outlet pipe and the two side walls of the liquid inlet box, which is about 200mm.
[0059] Embodiment 2:
[0060] The embodiment of the utility model provides a casting process of refined tin ingot or refined lead ingot using the quantitative casting device in embodiment 1, and its principle is:
[0061] The dosing pump is placed in the melt insulation crucible, the slag box, the pot-shaped casting device, and the tin mold. After preheating, the control system starts the dosing pump;
[0062] When the molten liquid fills the slow sedimentation box to filter out most of the mixed oxide slag, and the overflow hole of the pot-shaped caster begins to return tin, the traveling frame is started to start casting. The traveling frame moves with the tin mold. When the detection probe detects an empty tin mold, it will feedback a signal to the piston rod of the driving cylinder to extend, thereby tilting the pot-shaped caster and starting casting with the spout into the tin mold. When the detection probe detects a full mold, it will feedback a signal to the driving cylinder to pull up the pot-shaped caster and quickly return the traveling frame to complete the casting of the first mold. The traveling frame returns to the casting position, and then the traveling frame moves with the tin mold again. After the second mold is cast, it returns to the casting position and repeats the above casting process.
[0063] During the casting process, the pot-shaped caster casts before the metering pump supplies liquid. When the molten metal supplied by the metering pump reaches the pot-shaped caster, the liquid level of the molten metal in the pot-shaped caster has dropped, ensuring that the molten metal in the pot-shaped caster will not spill during the movement of the tin mold.
[0064] After comparison, it is found that the amount of slag inclusion in the formed tin ingot is effectively reduced when the device is used compared with the traditional casting method, thereby improving the forming quality of the tin ingot.
