Description

Technical Field

[0001] The invention relates to a flux spraying device. Background Art

[0002] Magnesium alloy flux forms a continuous and complete covering layer on the surface of magnesium melt by means of surface tension, isolating the air, preventing oxidation reaction, completely preventing oxidation of magnesium, and extinguishing the combustion of magnesium; it has good wetting and adsorption ability for non-metallic inclusions, and utilizes the density difference between flux and metal to remove metal inclusions from the solution along with the flux; currently magnesium alloy flux is all sprayed manually (this is because the traditional spraying equipment cannot be used for a long time in this industry after modification, and it is very easy to clog, which takes time to clean up and affects production), which has the problems of high labor intensity, poor safety, and uneven spraying. The uneven spraying will affect the actual use effect and cause defects in magnesium alloy products. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned defects. The inventors have found through long-term research that traditional spraying equipment is generally used for liquid spraying or granular spraying at room temperature. The reason why it cannot be used for a long time and is easily blocked after modification is that because the stirred magnesium alloy flux is in granular form, it needs to be preheated in the early stage. During stirring and spraying, it is easy to be affected by moisture and will gather at the discharge port during spraying, which will lead to a large amount of condensation at the discharge port and blockage after entering the discharge pipe. After continuous improvement, the inventors provide a solvent spraying device that can spray semi-automatically and evenly.

[0004] The present invention adopts the following technical solutions:

[0005] A flux spraying device, comprising: a mounting seat; the mounting seat comprises a mounting bracket; a silo, mounted on the mounting bracket; the silo is provided with a feed port, a discharge pipe, an air inlet pipe, and a stirring blade; the feed port is arranged at the top of the silo; the air inlet pipe is arranged on the right side of the silo, and is provided with an air inlet valve; the discharge pipe is provided on the left side of the silo, and is provided with a discharge valve, and the discharge pipe is provided with two, namely a first discharge pipe and a second discharge pipe; the first discharge pipe is located at the bottom end of the left side of the silo, the second discharge pipe is located above the first discharge pipe, and the tail end of the second discharge pipe is connected to the middle part of the first discharge pipe; the stirring blade is installed in the silo through a rotating shaft; a motor is mounted on the mounting bracket and is located below the silo; the motor is connected to the bearing seat and then connected to the rotating shaft driving the stirring blade through a sealing device; an air source is connected to the air inlet pipe; a spraying device is connected to the discharge pipe;

[0006] The spraying device includes a hose, a handheld hard tube, and a nozzle; the hose, the handheld hard tube, and the nozzle are connected in sequence; the other end of the hose is connected to the discharge pipe; the nozzle is in an elongated shape, and the opening gradually increases, and the nozzle piece above the nozzle is longer than the nozzle piece below; the opening gradually increases, so that while the spray is concentrated, an umbrella surface is formed, and the nozzle piece above the nozzle is longer than the nozzle piece below, so that when the material is sprayed, it is blocked by the nozzle piece above, so that the material will not be lifted upward during spraying.

[0007] Preferably, the discharge valve includes a first discharge valve installed on the first discharge pipe and a second discharge valve installed on the second discharge pipe.

[0008] The silo is provided with a first discharge pipe and a second discharge pipe, which can generate a certain circulating airflow inside while discharging the material to ensure that the discharge pipe will not be blocked, and by adjusting the first discharge valve and the second discharge valve, the spraying speed can be controlled according to the on-site production situation.

[0009] Preferably, the air source is connected to a pressure gauge and then to the air inlet pipe, so that the air pressure can be monitored in real time.

[0010] Preferably, the stirring blade is divided into a first stirring blade and a second stirring blade; the first stirring blade is installed at the bottom of the silo; the second stirring blade is installed at the upper end of the first stirring blade and is located in the middle of the silo; this design ensures more uniform stirring, because the magnesium alloy flux is granular and cannot be driven from above during stirring, while double-layer blades or multi-layer blades are provided, so that stirring can be performed in multiple places in the vertical direction to ensure that the material in the silo is evenly stirred.

[0011] Preferably, the sealing device is a graphite packing seat, which is corrosion-resistant and has better sealing performance.

When moving, the base plate design is more stable and not easily damaged.

[0022] In order to make the purpose and technical solution of the present invention clearer, the present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0023] like Figure 1 to Figure 4 The flux spraying device shown in the figure comprises: a mounting base 1; the mounting base comprises a mounting bracket 11; a silo 2, mounted on the mounting bracket 11; the silo 2 is provided with a feed port 3, a discharge pipe 4, an air inlet pipe 5, and a stirring blade; the feed port 3 is provided at the top of the silo; the air inlet pipe 5 is provided on the right side of the silo 2, and is provided with an air inlet valve 51; the discharge pipe 4 is provided on the left side of the silo, and is provided with a discharge valve, and the discharge pipes are provided with two, namely a first discharge pipe 41 and a second discharge pipe 42; the first discharge pipe Located at the bottom end of the left side of the silo 2, the second discharge pipe 42 is located above the first discharge pipe 41, and the tail end of the second discharge pipe 42 is connected to the middle part of the first discharge pipe 41; the stirring blade is installed in the silo through a rotating shaft; the motor 71 is installed on the mounting bracket and is located below the silo 2; the motor 71 is connected to the bearing seat 72 and connected to the rotating shaft driving the stirring blade through a sealing device 73; an air source (not shown in the figure) is connected to the air inlet pipe 5; a spraying device is connected to the discharge pipe 4.

[0024] Preferably, the discharge valve includes a first discharge valve 411 installed on the first discharge pipe and a second discharge valve 421 installed on the second discharge pipe.

[0025] The silo is provided with a first discharge pipe 41 and a second discharge pipe 42, which can generate a certain circulating airflow inside the silo while discharging the material to ensure that the discharge pipe 4 will not be blocked, and by adjusting the first discharge valve 411 and the second discharge valve 421, the spraying speed can be controlled according to the on-site production situation.

[0026] Preferably, the air source is connected to a pressure gauge (not shown in the figure) and then connected to the air inlet pipe, so that the air pressure can be monitored in real time.

[0027] Preferably, the stirring blades are divided into a first stirring blade 61 and a second stirring blade 62; the first stirring blade 61 is installed at the bottom of the silo; the second stirring blade 62 is installed at the upper end of the first stirring blade, located in the middle of the silo; this design ensures more uniform stirring, because the magnesium alloy flux is granular, and the upper part cannot be driven during stirring, and the double-layer blades or multi-layer blades are set, so that stirring can be performed in multiple places in the vertical direction to ensure that the material in the silo is evenly stirred.

[0028] Preferably, the sealing device 73 is a graphite packing seat, which is corrosion-resistant and has better sealing performance.

[0029] Preferably, a bottom plate 12 is fixedly connected below the mounting frame 11 of the mounting seat 1 .

[0030] Preferably, a plurality of lifting rings 13 are fixed above the mounting frame 11 of the mounting seat 1 .

[0031] The design of the bottom plate 12 makes the equipment more stable when placed on a workbench. Because magnesium alloy production is basically a workbench that goes up and down via steps, a lifting ring is designed and it is moved by a crane. When moving, the bottom plate design is more stable and not easily damaged.

[0032] Preferably, the spraying device comprises a hose 81 , a handheld hard tube 82 , and a nozzle 83 ; the hose 81 , the handheld hard tube 82 , and the nozzle 83 are connected in sequence; and the other end of the hose 81 is connected to the discharge pipe 4 .

[0033] Preferably, the nozzle 83 is in the shape of an elongated strip, and the opening gradually increases, and the nozzle piece 831 above the nozzle is longer than the nozzle piece 832 below the nozzle; the opening gradually increases, so that an umbrella surface is formed while the spray is concentrated, and the nozzle piece above the nozzle is longer than the nozzle piece below. When the material is sprayed out, it is blocked by the nozzle piece above, so that the material will not be lifted upwards during spraying.

[0034] Preferably, Figure 5As shown, a through rod 9 is also provided, which is an L-shaped structure. The long end of the L-shape is the same length as the air intake pipe 5 to avoid damaging the stirring equipment by inserting too deeply when passing through the air intake pipe 5. The short end of the L-shape through rod is provided with a tail hook 91 for hanging on the mounting frame.

[0035] In summary, the beneficial effects of the present invention are:

[0036] 1. The front end provides a controlled stable pressure through the air source, the middle end stirs and flows in the silo, and the double-tube design allows the silo to have two discharge ports, avoiding the traditional equipment from gathering and condensing in one place. The two discharge ports of the present invention allow the material to be discharged at two ports, reducing the amount of accumulation and residence time at a single place, and avoiding blockage of the discharge pipe.

[0037] 2. By adjusting the first discharge valve and the second discharge valve, the discharge speeds of the two discharge ports can be made inconsistent, forming a circulation inside the silo. When used in conjunction with a stirring device, the material can be further reduced in time for gathering at the discharge port, avoiding material coagulation and subsequent clogging of the discharge port, thus solving the problem that traditional equipment cannot be used. It also allows staff to control the spraying speed according to on-site production conditions.

[0038] 3. In addition, the nozzle has a unique design structure, so that the stirred magnesium alloy flux is sprayed evenly and does not rise.

[0039] Fourth, the equipment can be placed on the workbench more stably. Because magnesium alloy production is basically a workbench, which is moved up and down by steps, a lifting ring is designed and moved by a crane. When moving, the bottom plate is designed to be more stable and not easily damaged.

[0040] 5. The through rod is of L-shaped structure, and the long end of the L is the same length as the air inlet pipe to avoid damaging the stirring equipment by inserting too deeply into the air inlet pipe; the short end of the L-shaped through rod is provided with a tail hook for hanging on the mounting frame.

[0041] 6. When using an external spray device, after use, the spray device is left stationary. At this time, the material is easy to condense in the nozzle and cannot be used directly next time, and needs to be unblocked. The external design allows two identical spray devices to be replaced. The next time spraying, one is unblocked and the other can be used directly for spraying.
