Description

Technical Field

[0001] The present application relates to the technical field of metal smelting or casting, and in particular to a device and method for clearing and cleaning a magnesium alloy liquid conveying pipe. Background Art

[0002] In the magnesium alloy die-casting industrial production process, a quantitative pouring pump is used to transport 650-690℃ magnesium alloy liquid from the machine-side pouring furnace to the melting cup of the die-casting machine, and a die-cast magnesium alloy product is obtained by the die-casting process. During the die-casting process, the machine-side pouring furnace needs to be replenished with magnesium alloy liquid in a timely manner. In the past traditional process, the consumed magnesium liquid was replenished by transporting magnesium alloy ingots into the machine-side pouring furnace for melting through equipment.

[0003] In the existing direct supply of magnesium liquid production process, the magnesium liquid smelted in the alloy workshop is directly transported and transported to the machine-side casting furnace to replenish the magnesium liquid, which reduces the intermediate ingot-melting process and saves a lot of electricity and manpower and material resources. In the process of direct supply of magnesium liquid, the conveying pipe is an indispensable equipment. The function of the conveying pipe is to transport the high-temperature molten magnesium liquid in the transfer furnace transported from the alloy workshop into the machine-side casting furnace. Because the high-temperature magnesium liquid is easy to burn, oxidize and slag, and there is residual bottom slag in the transfer furnace, the conveying pipe is prone to blockage during use, so it is necessary to regularly clear and clean the conveying pipe to ensure the normal use of the conveying pipe. The main components of the magnesium slag that causes pipe blockage are generally a mixture of MgO, KCl, MgCl2, CaCl2, FeCl3, Mg3N2, Mn and other components.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present application. It is understandable that the drawings are only provided for reference and illustration, and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0045] Specifically, Figure 1 As shown, a magnesium alloy liquid delivery pipe unclogging and cleaning device is provided in an embodiment of the present application, and the device is mainly used to clean the inner wall debris of the magnesium alloy liquid delivery pipe 400, wherein the magnesium alloy liquid delivery pipe 400 is used to connect to a machine-side furnace, wherein two machine-side furnaces are provided, and one of the machine-side furnaces is connected to the other machine-side furnace through the magnesium alloy liquid delivery pipe 400, so that the magnesium liquid in one machine-side furnace enters the other machine-side furnace, so that the magnesium liquid in the other machine-side furnace is conveniently delivered to the die-casting machine through a pump.

[0046] Among them, in the above structure, when the magnesium liquid is transported for a long time, sediment will be generated on the inner wall of the delivery pipe 400. The main components of the sediment are a mixture of MgO, KCl, MgCl2, CaCl2, FeCl3, Mg3N2, Mn and other components. During the long-term transportation process, it will seriously affect the traffic efficiency of the pipeline. If it is not handled in time, it will cause blockage and the transportation effect cannot be achieved.

[0047] For the above-mentioned problem, under normal circumstances, the delivery pipe 400 is disassembled and cleaned after working for about 15 days, and the cleaning is done manually, which may result in low efficiency and unclean cleaning.

[0048] In view of the above problems, the present application provides a magnesium alloy liquid conveying pipe dredging and cleaning device, which is generally composed of a cleaning pool 100, a lifting support device 200 and a conveying and cleaning device 300.

[0049] Among them, the cleaning tank 100 in the embodiment of the present application contains an acidic cleaning liquid, and the main components of the acidic cleaning liquid include acetic acid (i.e., acetic acid CH3COOH) or glacial acetic acid (i.e., anhydrous acetic acid). Specifically, a large amount of water is added to the cleaning tank 100, acetic acid is added to the water, and the pH value in the cleaning tank 100 is adjusted by the amount of acetic acid added. In the embodiment of the present application, the pH value in the cleaning tank 100 is adjusted to be an acidic solution as a whole.

[0050] After the solution in the cleaning tank 100 is prepared, the delivery pipe 400 is placed on the lifting support device 200. In this application, Figure 1-2 As shown, the opening positions of both ends of the delivery pipe 400 are set corresponding to the upper position of the cleaning pool 100, and a delivery cleaning device 300 is set in the cleaning pool 100. The delivery cleaning device 300 flushes the inner wall of the delivery pipe 400 with the acid solution in the cleaning pool 100 through the first delivery pipe 320 and the second delivery pipe 330, wherein the delivery cleaning device 300 includes a delivery pump 310, a first delivery pipe 320 and a second delivery pipe 330, and the delivery pump 310 is placed in the cleaning pool 100 to facilitate the delivery pump 310 to absorb and deliver the acid solution The first delivery pipe 320 and the second delivery pipe 330 are both connected to the output end of the delivery pump 310, and the end position of the first delivery pipe 320 away from the delivery pump 310 is corresponding to the opening of one end of the delivery pipe 400, so that the delivery pump 310 can flush the acidic solution into the delivery pipe 400 through the first delivery pipe 320, and the end position of the second delivery pipe 330 away from the delivery pump 310 is corresponding to the opening of the other end of the delivery pipe 400, so that the delivery pump 310 can flush the acidic solution into the delivery pipe 400 through the second delivery pipe 330.

[0051] In the embodiment of the present application, the purpose of setting the conveying device is to place the acid solution in the conveying pipe 400. In order to continuously place the acid solution in the conveying pipe 400, a lifting support device 200 is required to tilt the conveying pipe 400, specifically:

[0052] The lifting support device 200 mainly includes a support base 210, a support frame 220 and a lifting drive device 230. Figure 2 As shown, the support base 210 is arranged at one side of the cleaning pool 100 and close to one side of the cleaning pool 100. A rotating shaft 211 is arranged at the top of the support base 210 close to one side of the cleaning pool 100. The rotating shaft 211 is connected to the support frame 220 so that the support frame 220 and the support base 210 can rotate relative to each other.

[0053] More specifically, Figure 2 As shown, the support frame 220 is a rectangular support frame 220 , and is connected to the rotating shaft 211 at one side of the rectangular support frame 220 .

[0054] Preferably, in the embodiment of the present application, the support frame 220 can also be set to other shapes.

[0055] A limiting device 221 is provided on the support frame 220, and the limiting device 221 is fixed on the support frame 220. In the present application, the main body of the support frame 220 itself is a steel truss structure, and the limiting device 221 is a plurality of steel bars welded on the support frame 220, and a limiting groove is formed between the plurality of steel bars. The width of the limiting groove just accommodates the conveying pipe 400 itself, so that the conveying pipe 400 is limited and fixed by the limiting device 221.

[0056] Preferably, in the embodiment of the present application, the limiting device 221 may also be provided with a fixing ring, a fixing claw, or other structure capable of limiting the conveying pipe 400. As long as the structure can limit and fix the conveying pipe 400, it should be considered within the protection scope of the present application.

[0057] In the above, after the limiting device 221 limits and fixes the delivery pipe 400, the opening positions at both ends of the delivery pipe 400 are located at the upper position of the cleaning pool 100. The upper position of the cleaning pool 100 is specifically when the acidic solution flows out from the opening of the delivery pipe 400, the acidic solution just falls into the cleaning pool 100.

[0058] After the limiting device 221 fixes the conveying tube 400, the lifting drive device 230 is driven, so that the support frame 220 drives the conveying tube 400 to flip around the rotating axis 211, wherein the lifting drive device 230 in the embodiment of the present application is a linear drive mechanism, which includes two support rods, both of which support the side of the support frame 220 away from the rotating axis 211, and an adjusting rod is provided at the bottom position of the support rod, and the adjusting rod is rotatably connected to the support rod. When the adjusting rod is rotated, the support rod moves up and down, thereby driving the support frame 220 to flip.

[0059] Preferably, in the embodiment of the present application, the lifting drive device 230 can be further selected as an air push rod, a hydraulic rod or other device with linear lifting function. As long as the device can drive the support frame 220 to rotate around the rotating axis 211, it should be considered within the protection scope of the present application.

[0060] In the present application, when the conveying pipe 400 is placed on the support frame 220, the lifting drive device 230 drives the support frame 220 to rotate to an angle, which is set to about 15 degrees in the present application, so that the inclination angle of the conveying pipe 400 is 15 degrees.

[0061] In the above description, the inclination angle is the angle formed between the plane where the conveying pipe 400 is located and the horizontal plane.

[0062] At this angle, the height of the mouth of the delivery pipe 400 is higher than the body of the delivery pipe 400 itself.

[0063] When the delivery pipe 400 is adjusted at this angle, when the delivery pump 310 delivers the acidic solution into the pipe body of the delivery pipe 400 through the first delivery pipe 320 and the second delivery pipe 330, since the support frame 220 is set to be inclined at an angle of 15 degrees, the acidic solution in the pipe body is filled into the delivery pipe 400, and the acidic solution in the delivery pipe 400 does not overflow, which facilitates the acidic solution to react and remove the dirt inside the delivery pipe 400.

[0064] The dirt in the delivery pipe 400 is mainly composed of a mixture of MgO, KCl, MgCl2, CaCl2, FeCl3, Mg3N2, Mn and the like. When it comes into contact with an acidic solution, the following reaction usually occurs:

[0065] MgO+2CH3COOH===(Mg 2+ )+(2CH3COO - )+2H2O

[0066] Mn+2CH3COOH=Mn(CH3COO)2+H2↑

[0067] Mg3N2+6H2O→3Mg(OH)2+2NH3

[0068] At the same time, magnesium oxide (MgO) reacts with water to form magnesium hydroxide (Mg(OH)2) precipitate;

[0069] Among them, magnesium hydroxide (Mg(OH)2) precipitate reacts with acetic acid to generate soluble substance magnesium acetate. The reaction is as follows:

[0070] Mg(OH)2+2CH3COOH→(CH3COO)2Mg+2H2O

[0071] Since the acidic solution in the delivery pipe 400 is of a certain volume, the acetic acid therein may not be able to react with all the magnesium hydroxide. At this time, under the flushing of high-temperature weak acid water, Mg(OH)2, water and acetic acid fully form a mixed suspension, which can be separated from the inner wall of the pipe after the solution is discharged from the delivery pipe 400.

[0072] After the acid solution is poured into the delivery pipe 400, the reaction needs to be maintained for a period of time. In order to fully react, in the embodiment of the present application, the acid solution soaking time is 20-30 hours.

[0073] In the embodiment of the present application, a heating device 222 is also provided. Figure 4 As shown, the heating device 222 is disposed on the support frame 220. After the acid solution is poured into the delivery pipe 400, the heating device 222 continuously heats the delivery pipe 400 at a temperature of about 100-200 degrees Celsius to promote the reaction.

[0074] For further reaction, a vibration device is also provided in the present application, and the vibration device is arranged on the support frame 220 (the vibration device is not shown in the drawings, but it does not affect the technical understanding of the embodiment of the present application). Specifically, the vibration device is arranged between the support frame 220 and the limit device 221. Through the vibration action of the vibration device, the limit device 221 will be vibrated as a whole, and its vibration frequency is about 1-5HZ. The vibration direction of the vibration device is to vibrate along the plane position where the conveying pipe is placed, so that the acidic solution can be driven to impact the inner wall of the pipe to a certain extent, which is convenient for removing the dirt.

[0075] Through the above-mentioned vibration process, the delivery pipe 400 can be vibrated after being heated, so that the dirt can be quickly peeled off from the inner wall of the delivery pipe 400 after the dirt reacts with the acid solution, thereby facilitating the cleaning of the inner wall of the delivery pipe 400.

[0076] Preferably, since the solution in the delivery pipe 400 has only a certain volume, when the volume of dirt in the delivery pipe 400 is large, it is necessary to fully react the dirt inside the delivery pipe. In the embodiment of the present application, when the vibration time lasts for 1.5-2 hours, it is necessary to stop the vibration, turn over the delivery pipe 400, pour out the acidic solution in the delivery pipe 400, and place a new acidic solution in the delivery pipe 400 to thoroughly react the dirt in the delivery pipe 400.

[0077] When the reaction is completed, the lifting drive device 230 is driven, and the lifting drive device 230 pushes the support frame 220 to flip around the rotating axis 211, and moves the conveying pipe 400 to a negative angle of 15 degrees, wherein the negative angle of 15 degrees is the angle between the plane where the conveying pipe 400 is located and the horizontal plane. To avoid ambiguity, the angle is positive 15 degrees during the above initial flipping. When the angle of the conveying pipe 400 is 0 degrees, the conveying pipe 400 is placed horizontally.

[0078] When the delivery pipe 400 is at a negative angle of 15 degrees, the opening height of the delivery pipe 400 is lower than the height of the delivery pipe 400 itself, so that the acid solution in the delivery pipe 400 is poured out to pour the acid solution into the cleaning pool 100 .

[0079] In the present application, the cleaning pool 100 is provided with a first area 120 and a second area 130, such as Figure 3As shown, the first area 120 and the second area 130 are separated by an isolation plate 110, wherein a plurality of through holes 111 are provided on the isolation plate 110, and the through holes 111 are used to connect the first area 120 and the second area 130 so that the acidic cleaning liquid in the first area 120 enters into the second area 130 through the through holes 111 or the acidic cleaning liquid in the second area 130 enters into the first area 120 through the through holes 111, wherein the delivery pump 310 is provided in the first area 120, and an end position of the first delivery pipe 320 away from the delivery pump 310 and an end position of the second delivery pipe 330 away from the delivery pump 310 are both located in the second area 130.

[0080] Furthermore, in the embodiment of the present application, the two pipe openings of the delivery pipe 400 are both located directly above the second area 130 , so as to facilitate pouring the acid solution in the delivery pipe 400 into the second area 130 .

[0081] Meanwhile, the aperture size of the through hole 111 provided on the isolation plate 110 is smaller than the size of the suspension, so as to prevent the solid in the suspension after the reaction from entering the second area 130 .

[0082] After pouring the solution in the delivery pipe 400, the delivery pump 310 is driven. The delivery pump 310 uses the acidic solution in the first area 120 through the first delivery pipe 320 or the second delivery pipe 330 to perform high-pressure cleaning on the inner wall of the delivery pipe 400. To facilitate flushing, in the embodiment of the present application, a valve switch is provided on the first delivery pipe 320. When the valve switch is opened, both the first delivery pipe 320 and the second delivery pipe 330 flush the delivery pipe 400. When the valve switch is closed, the acidic solution only flushes the inside of the delivery pipe 400 through the second delivery pipe 330.

[0083] Correspondingly, a valve switch may also be provided in the second delivery pipeline 330 .

[0084] In the embodiment of the present application, a protective cover 500 is further provided to protect the opening positions at both ends of the delivery pipe 400 to prevent the acidic solution from splashing to external positions in the cleaning tank 100 .

[0085] Preferably, in the embodiment of the present application, the valve switch is closed to facilitate the circulation flushing of the inner wall of the delivery pipe 400.

[0086] In this application, the cycle rewash time lasts for 30 minutes.

[0087] By continuing the flushing time, the inner wall of the delivery pipe 400 can be effectively treated and the residual dirt can be avoided.

[0088] Among them, the pressure value of high-pressure flushing is between 2.5MPa and 4.0MPa.

[0089] This application also provides a cleaning method, specifically:

[0090] Step 1: placing an acid cleaning solution in the cleaning tank 100 and placing the delivery pipe 400 on the support frame 220;

[0091] Step 2: Start the lifting drive device 230 to tilt the delivery pipe 400 so that the heights of the openings at both ends of the delivery pipe 400 are higher than the height of the delivery pipe 400;

[0092] Step 3: Place one end of the first delivery pipe 320 and the second delivery pipe 330 at the openings at both ends of the delivery pipe 400, start the delivery pump 310, and the delivery pump 310 delivers the acid cleaning solution to the inner position of the delivery pipe 400 through the first delivery pipe 320 and the second delivery pipe 330, stop starting the delivery pump 310, heat the delivery pipe 400 through the heating device 222, and let the delivery pipe 400 stand for 20-30 hours;

[0093] Step 4: Start the lifting drive device 230, tilt the delivery pipe 400 so that the height of the openings at both ends of the delivery pipe 400 is lower than the height of the delivery pipe 400 body, and discharge the acid cleaning liquid from the delivery pipe 400;

[0094] Step 5: Start the delivery pump 310 to periodically and continuously flush the inner wall of the delivery pipe 400 through the first delivery pipe 320 or the second delivery pipe 330 to complete the cleaning process.

[0095] Most of the dirt can be removed during the above steps, but in order to achieve a good cleaning effect, a spray gun is also provided in the present application after step five is completed. The spray gun is connected to a water pipe, and the water pipe is connected to the delivery pump 310, so that the delivery pump 310 delivers the acidic liquid to the spray gun, so that the acidic liquid is sprayed out through the spray gun. The spray gun is a movable gun head, and the pressure range of the spray is between 2.5MPa and 4.0MPa. When the acidic liquid is sprayed from the spray gun, the impact force of the sprayed acidic liquid drives the spray gun to move in the pipeline of the delivery pipe 400, so that the sprayed acidic liquid flushes the inner wall of the pipeline, so as to remove the residual dirt and achieve the purpose of a clean pipeline.

[0096] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
