Description

[0002] Atomization powder making technology is the main method for producing metal and alloy powders. The alloy is heated to a certain temperature in a melting crucible under vacuum or gas protection heating conditions, and the melting crucible is tilted by a hydraulic or electric drive device to pour the molten metal into the tundish crucible. The molten metal enters the atomization zone through the center hole of the guide tube at the bottom of the insulation tundish crucible. In the atomization zone, high-pressure inert gas forms a high-speed jet through the atomization nozzle, breaking the molten metal into fine droplets. These droplets fly in the atomization chamber below and quickly cool and solidify, eventually becoming micron-sized powder particles.

[0003] In the prior art, the pouring process of pouring the liquid in the melting crucible into the tundish crucible is usually performed by an operator manually operating a rocker or button to drive a hydraulic or electric drive device to tilt the melting crucible for pouring. This manual pouring method will cause the flow rate of the liquid to be unable to be maintained within a stable value range during the pouring process, and the flow rate of the liquid will affect the quality of the produced metal powder. The unstable liquid flow rate during the pouring process will result in poor quality of the metal powder.

[0029] Reference Figure 1-Figure 3 Atomization powder making technology is the main method for producing metal and alloy powders. In the prior art, the operator usually manually operates a rocker or button to drive the hydraulic or electric drive device to tilt the melting crucible so that the liquid in the melting crucible can be poured into the tundish crucible. This manually operated pouring method will cause the flow rate of the liquid during the pouring process to not be maintained within a stable numerical range, resulting in poor quality of the metal powder. Manual pouring is highly dependent on the operator's operating ability, requires a lot of time for training, and has high labor costs. In addition, in the process of training beginners in pouring operations, there is no dedicated training device, and only the pouring device in production can be used for pouring. The temperature of the liquid is high, and beginners are prone to operating errors and cause safety accidents. It also takes up the normal production time of the pouring device, increasing production costs.

[0030] Reference Figure 1-3 The present application provides an aerosolized powder making and pouring training device, including a shell 6, in which a liquid container 7 and a buffer container 4 are arranged. The alloy is melted into liquid in the liquid container 7, and the liquid metal is poured from the liquid container 7 into the buffer container 4.

[0031] The liquid container 7 is connected to the support part 5 . The support part 5 includes a support shaft and a bracket. The liquid container 7 rotates around the support shaft at different angles, and the bracket supports the liquid container 7 .

[0032] The liquid container 7 rotates around the support shaft and is tilted at different angles, thereby changing the speed at which the liquid metal in the liquid container 7 flows out, that is, changing the mass flow rate of the liquid metal in the liquid container 7. The mass flow rate refers to the mass of the fluid passing through the effective cross section of a closed pipe or an open slot per unit time. When the liquid metal can flow out of the liquid container 7, the greater the tilt angle of the liquid container 7, the greater the mass flow rate of the liquid in the liquid container 7.

[0033] An angle sensor is provided on the support shaft. When the liquid container 7 is in the initial position, the angle value of the angle sensor is 0°. When the liquid container 7 rotates, the angle sensor detects the rotation angle of the liquid container 7 relative to the initial position.

[0034] It can be arranged that when the liquid container 7 is in the initial position, the central axis of the liquid container 7 is in a vertical state.

[0035] Optionally, the support extends in a vertical direction. In some embodiments, the support can be changed in height to accommodate different flow requirements of different liquid metals.

[0036] A vacuum generator 1 is provided at the bottom of the buffer container 4, and a guide tube is provided at the bottom of the buffer container 4. When the liquid is poured into the buffer container 4, it flows into the guide tube, and the vacuum generator 1 creates a negative pressure environment. The liquid enters the atomization area through the guide tube, and the high-pressure inert gas in the atomization area forms a high-speed jet through the atomization nozzle, breaking the liquid into fine droplets. These droplets fly in the atomization chamber below and quickly cool and solidify, and finally become micron-sized powder particles.

[0037] The aerosolized powder making and pouring training device also includes a controller, which is electrically connected to the support part 5, and the controller outputs a signal to the support part 5 to rotate the support part 5 at different angles to drive the liquid container 7 to rotate at different angles. The controller is electrically connected to the angle sensor to receive the tilt angle value transmitted by the angle sensor in the form of an electrical signal.

[0038] The gas atomization powder making and pouring training device also includes a display connected to the controller for displaying parameters such as mass flow rate and pouring amount.

[0039] A first moving device 2 and a second moving device 3 are also provided at the bottom of the buffer container 4. The first moving device 2 is electrically connected to the controller, and the second moving device 3 is electrically connected to the controller.

[0040] It should be noted that the first moving device 2 drives the buffer container 4 to move in the horizontal direction, and the second moving device 3 drives the buffer container 4 to move in the vertical direction, so that the buffer container 4 can move in the horizontal and vertical directions, so that the liquid in the buffer container 4 can shake, thereby accelerating the speed at which the liquid in the buffer container 4 enters the guide tube, and making the liquid in the buffer container 4 more uniform, so that the metal powder generated after the liquid enters the atomization area is more uniform.

[0041] The aerosol powder making and pouring training device also includes at least two liquid level sensors 8, which are used to detect the liquid level height in the liquid container 7 and the liquid level height in the buffer container 4 respectively. The liquid level sensor 8 is connected to the controller, and the liquid level sensor 8 transmits the detected liquid level value to the controller in the form of an electrical signal.

[0042] In some embodiments of the present application, the liquid level sensor 8 is a contact liquid level sensor 8, such as a float liquid level transmitter, a magnetic liquid level transmitter, a immersion liquid level transmitter and a capacitive liquid level transmitter, and the contact part of the contact liquid level sensor 8 needs to be made of high temperature resistant material.

[0043] In some embodiments of the present application, the liquid level sensor 8 is a non-contact liquid level sensor 8, such as an ultrasonic liquid level transmitter and a radar liquid level transmitter. The non-contact liquid level sensor 8 is installed on the shell 6 and obtains the liquid level height in the liquid level container and the liquid level height in the buffer container 4 by emitting signal waves.

[0044] The non-contact liquid level sensor 8 can be arranged to be installed on the top surface of the shell 6 with the transmitting end facing downward to reduce the probability of liquid splashing onto the liquid level sensor 8 during the pouring process, reduce the probability of damage to the liquid level sensor 8, and be able to accurately obtain the liquid level height, which helps the controller to calculate the inclination angle of the liquid container 7 according to the actual liquid level height, so as to make the mass flow control during the pouring process more accurate.

[0045] The aerosolized powder making and pouring training device also includes an observation window 9 arranged on the shell 6. The operator can observe the pouring process inside the shell 6 through the observation window 9, thereby reducing the occurrence of safety accidents and facilitating subsequent inspection and maintenance.

[0046] The aerosolized powder making and pouring training device also includes a circulation branch, one end of which is connected to the inlet on the shell 6, and the alloy is poured into the liquid container 7 in the shell 6 from the inlet, and the other end of the circulation branch is connected to the vacuum generator 1.

[0047] The circulation branch includes a filter 10, a liquid circulation pump 12, a water tank 13 and a flow sensor 14 which are connected in sequence.

[0048] The filter 10 is arranged at a position of the circulation branch near the inlet of the shell 6, so that the flowing liquid in the circulation branch is filtered by the filter 10 and then enters the inlet of the shell 6 and the liquid container 7, thereby reducing the liquid impurities in the liquid container 7 and making the quality of the generated metal powder higher.

[0049] The liquid circulation pump 12 is electrically connected to the controller, and the liquid circulation pump 12 provides power for the liquid to flow in the circulation branch.

[0050] The flow sensor 14 is located on the circulation branch near the vacuum generator 1 to detect the mass flow of the liquid flowing out of the liquid container 7 .

[0051] The flow sensor 14 uploads a signal to the controller, and the controller obtains the mass flow of the liquid and outputs a signal to the display, so that the display shows the mass flow and records the mass flow at different times, so that the operator can get the current mass flow.

[0052] The controller can be set to output a curve graph of mass flow and time, which is convenient for operators to intuitively obtain the changes in mass flow.

[0053] In some embodiments, the controller is configured to calculate the mass flow average value / mass flow variance within a certain period of time according to the mass flow detection value detected by the flow sensor 14 .

[0054] The user can refer to the mass flow rate, mass flow rate average value and mass flow rate variance to judge the stability of pouring during the pouring process. The display receives the signal from the controller and displays the above values ​​for the user to observe directly.

[0055] The control is configured as follows: the current mass flow detected is obtained through the flow sensor 14; if the current mass flow is less than the preset mass flow, the support shaft is driven to rotate so that the inclination angle α of the liquid container 7 increases until the current mass flow reaches the preset mass flow; if the current mass flow is greater than the preset mass flow, the support shaft is driven to rotate so that the inclination angle α of the liquid container 7 decreases until the current mass flow reaches the preset mass flow.

[0056] It should be noted that if the preset mass flow rate is greater than the current mass flow rate, the liquid container 7 is rotated to increase the preset tilt angle so as to increase the liquid flow rate.

[0057] If the preset mass flow rate is equal to the current mass flow rate, the liquid container 7 is no longer rotated.

[0058] If the preset mass flow rate is less than the current mass flow rate, the liquid container 7 is rotated to reduce the tilt angle so as to slow down the flow speed of the liquid.

[0059] In the prior art, the pouring process is manually operated, and operators can only be trained through a pouring device in production. The present application is a training device that is automatically operated by a controller. Beginners can enhance their technical proficiency through the pouring training device of the present application, and can intuitively feel the relationship between the inclination angle of the liquid container 7 and the mass flow rate. The operation is more precise, the probability of safety accidents is low, and the personnel training time and labor costs are reduced.

[0060] The control is configured to: store the data of the current mass flow rate and the tilt angle α, and form a first logical relationship by corresponding the mass flow rate and the tilt angle; if the current mass flow rate is not equal to the preset mass flow rate, then in combination with the preset mass flow rate, the preset tilt angle is obtained according to the first logical relationship, and the support shaft is driven to rotate so that the liquid container 7 is rotated to the preset tilt angle. It can be rotated directly without observing the mass flow rate while rotating. The steps are simpler and convenient for beginners to operate.

[0061] The first logical relationship is the proportional relationship between the mass flow rate and the tilt angle. When the tilt angle reaches a critical point and the liquid can be poured out, the larger the tilt angle, the greater the mass flow rate, and the smaller the tilt angle, the smaller the mass flow rate.

[0062] The controller is electrically connected to the angle sensor, the support shaft of the support part 5, and the liquid level sensor 8. The controller receives the tilt angle α of the liquid container 7 detected by the angle sensor, the liquid level height h1 of the liquid container 7 detected by the liquid level sensor 8, and the liquid level height h2 of the buffer container 4. In the initial state of pouring, the time is 0s, the tilt angle of the liquid container 7 is 0, the liquid level height h10 of the liquid container 7 detected by the liquid level sensor 8, and the liquid level height h20 of the buffer container 4. At this time, the liquid container 7 has not started to tilt, and pouring is not in progress.

[0063] The controller is configured to: according to the liquid level height h1, the liquid level height h2 of the buffer container and the inclination angle α, in combination with the second logical relationship, calculate the current liquid mass M1 in the liquid container and / or the liquid mass M2 in the buffer container, respectively, at the beginning and end of a period of time, to obtain the liquid mass change △m1 inside the liquid container and / or the liquid mass change △m2 in the buffer container, and output a signal to the display to display the liquid mass change △m1 and / or △m2.

[0064] The second logical relationship is to calculate the liquid volume V1 in the liquid container and / or the liquid volume V2 in the buffer container according to the liquid level height h1, the liquid level height h2 of the buffer container and the inclination angle α, and then calculate the liquid mass M1 and / or the liquid mass M2 after obtaining the liquid density ρ.

[0065] Specifically, the second logical relationship is:

[0066] M=ρπd 2[(h)*tan(α)] / 8+ρπd 2 [(h)-(h)*(h)*tan(α1)] / 4;

[0067] In the above formula, M is the mass of the liquid in the container, ρ is the density of the liquid in the container, d is the diameter of the container, h is the liquid level height of the liquid in the container, and α is the inclination angle of the liquid container.

[0068] The following describes in detail how to calculate the pouring volume:

[0069] At time t1, the liquid volume V11 in the liquid container 7 is:

[0070] V11=π(d1) 2 [(h11)*tan(α1)] / 8+π(d1) 2 [(h11)-(h11)*(h11)*tan(α1)] / 4;

[0071] In the above formula: d1 is the diameter of the liquid container 7; α1 is the tilt angle of the liquid container 7 at time t1; h11 is the liquid level height of the liquid container 7 at time t1.

[0072] At time t1, the mass M11 of the liquid in the liquid container 7 is:

[0073] M11=(V11)*ρ;

[0074] In the above formula: ρ is the density of the liquid in the liquid container;

[0075] At time t1, the liquid volume V21 in the liquid container 7 is:

[0076] V21=π(d2) 2 *(h21) / 4;

[0077] In the above formula: d2 is the diameter of the buffer container 4; h21 is the liquid level height h21 of the buffer container 4 at time t1;

[0078] At time t1, the mass M21 of the liquid in the buffer container 4 is:

[0079] M21=(V21)*ρ;

[0080] In the above formula: ρ is the density of the liquid in the buffer container;

[0081] At time t2, the liquid volume V12 in the liquid container 7 is:

[0082] V12=π(d1) 2 [(h12)*tan(α2)] / 8+π(d1) 2[(h12)-(h12)*(h12)*tan(α2)] / 4;

[0083] In the above formula: d1 is the diameter of the liquid container 7; α2 is the tilt angle of the liquid container 7 at time t2; h12 is the liquid level height of the liquid container 7 at time t2.

[0084] At time t2, the mass M12 of the liquid in the liquid container 7 is:

[0085] M12=(V12)*ρ;

[0086] In the above formula: ρ is the density of the liquid in the liquid container;

[0087] At time t2, the liquid volume V22 in the liquid container 7 is:

[0088] V22=π(d2) 2 *(h22) / 4;

[0089] In the above formula: d2 is the diameter of the buffer container 4; h22 is the liquid level height of the buffer container 4 at time t2;

[0090] At time t2, the mass M22 of the liquid in the buffer container 4 is:

[0091] M22=(V22)*ρ;

[0092] In the above formula: ρ is the density of the liquid in the buffer container;

[0093] From time t1 to time t2, the change in mass △m1 of the liquid inside the liquid container 7 is:

[0094] △m1=M12-M11;

[0095] In the above formula: M11 is the mass of liquid in the liquid container 7 at time t1; M12 is the mass of liquid in the liquid container 7 at time t2;

[0096] From time t1 to time t2, the change in mass △m2 of the liquid inside the buffer container 4 is:

[0097] △m2=M22-M21;

[0098] In the above formula: M21 is the mass of liquid in the buffer container 4 at time t1; M22 is the mass of liquid in the buffer container 4 at time t2.

[0099] In some embodiments, the controller calculates the liquid mass change △m1 inside the liquid container 7 and the liquid mass change △m2 inside the buffer container 4, and outputs a signal to the display so that the display displays △m1 and △m2, making it convenient for the operator to obtain the pouring amount.

[0100] In some embodiments, the controller calculates the total value of △m1 and △m2, and outputs a signal to a display, so that the operator can obtain the pouring amount.

[0101] In the prior art, when the shape of the crucible or the tundish crucible is changed, or when the height position of the tundish crucible or the crucible is changed, the operator needs to adapt to the new working state again, which makes it difficult for the liquid flow rate to be stabilized within a certain numerical range during the pouring process, affecting the effect of the powder generated after pouring, and causing trouble for the operator's work; if machine operation is performed, different models of equipment still follow the preset pouring operation due to differences in crucible diameter and pouring height, and the flow rate cannot reach the preset value, making it difficult to adapt to different working conditions.

[0102] In the gas atomization powder pouring training device provided by the present application, the liquid container 7 is a smelting crucible, the buffer container 4 is a tundish crucible, and the liquid is poured from the smelting crucible into the tundish crucible. The position and model of the smelting crucible can be adjusted, and the high position and model of the tundish crucible can be adjusted to meet different model and position requirements.

[0103] When the liquid container 7 and the buffer container 4 change their models and positions, the controller of the aerosolized powder making and pouring training device of the present application obtains the changed mass flow rate and rotation angle, and recalculates the first logical relationship to adapt to the new working conditions and has adaptive capabilities.

[0104] When the liquid container 7 and the buffer container 4 change their models and positions, the controller of the aerosolized powder making and pouring training device of the present application obtains the changed mass flow rate and inclination angle, and recalculates the first logical relationship, and changes the inclination angle of the liquid container 7 according to the newly generated first logical relationship. Compared with the prior art, the aerosolized powder making and pouring training device of the present application is more flexible, and the correspondence between the mass flow rate and the rotation angle is more precise, which is a significant improvement over the prior art.

[0105] The controller of the aerosol powder making and pouring training device of the present application stores the mass flow rate and rotation angle of liquid containers 7 and buffer containers 4 of different models and positions, and stores the obtained first logical relationship to form an automatic pouring system model. There is no need for additional training of the system model subsequently. Each pouring process is recorded, the steps are relatively simple, no extra time is required, and labor costs are reduced.

[0106] In some embodiments, the liquid flowing in the circulation pipeline is water added as the training liquid during training, and the circulating water pump is turned on to provide power for water circulation, thereby reducing the probability of safety accidents caused by improper operation by beginners.
