Description

Technical Field

[0001] The invention relates to the technical field of metallurgy, and more particularly to a sampling probe and automatic separation equipment and a use method thereof. Background Art

[0002] In metallurgical production, the type and quantity of auxiliary materials to be added and the smelting end point need to be determined based on the temperature, carbon content and other chemical components of the metal liquid in the molten pool. To accurately grasp these chemical components, samples need to be taken and sent to the laboratory for analysis through a pneumatic sample delivery device. At present, the smelting area mostly uses a temperature measurement and sampling composite probe installed on a temperature measuring gun, and the temperature measuring gun is manually inserted into the smelting liquid to complete the operation. However, the separation operation of the probe sample after sampling can only be done manually, which restricts the overall automation level of the smelting area.

[0003] The outer side of the sampling probe currently in use is composed of a cylindrical paper shell, and the interior has various forms depending on the different metal sample mold boxes. One of the more common forms is a cylindrical flat sample, whose mold box shell is a two-piece structure and is fixed by a metal clip. This metal clip is used to ensure that the two-piece mold shell of the sampled metal liquid always remains in a combined state during the solidification process. The obtained sample is a regular cylinder with no burrs on the edges.

[0004] Chinese patent CN203545142U discloses a device for automatically revealing a sample body, wherein the probe is first fixed by means of a supporting device on its outer surface, the probe area with the sample is separated by a separation device, and the sample with the mold shell is squeezed out of the separated area of ​​the probe by a punch. The filling material containing the shell component and the sample is introduced into the shell removal device through an introduction device, wherein the shell component includes a clip for keeping the sample shell in a closed state during sampling. The shell removal device includes a bottom plate, a vibration motor, a centrifugal device, a collision body, and the like. The bottom plate is tilted downward, and a vibration motor is installed at the bottom. Through the vibration of the bottom plate, the sample is moved toward the centrifugal device in the shell removal device. The gap size below the centrifugal device can only pass through the separated sample and shell. The unseparated sample and shell obtain an impulse toward the collision body through the centrifugal device. Through the collision of the collision body, the object will decompose in most cases. The decomposed sample, shell components and filling materials move toward the sample removal area through the gap below the centrifugal device. Before reaching the sample removal area, they are blocked by a barrier layer. The barrier layer has a channel for the sample shell and filling materials. The sample shell components and filling materials are separated through this channel, but the sample cannot pass through this channel due to size reasons. Therefore, the sample is guided by the barrier layer and finally enters the sample removal area. This device has many actuators, a complex structure, and is difficult to ensure reliability. The cost is high and the subsequent maintenance work is large. The method of using a centrifugal device to make the shell component with a clamp collide with the collision body can only ensure that the sample and the shell component will be separated in most cases. It cannot handle the situation where the sample and the shell component are difficult to separate due to the clamp being assembled too tightly, and there is no constraint on the posture of each component. It is easy to get stuck in the gap between the centrifugal device and the bottom plate due to the arbitrary posture of the components. Summary of the invention

[0061] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0062] Please combine Figure 1 , Figure 2As shown, a sampling probe provided by the present invention includes a probe tail area 1 and a probe sampling area 2 connected to the front end of the probe tail area 1; the probe sampling area 2 includes a paper shell, a two-piece mold shell component 3 arranged in the paper shell, and a sample 4 arranged inside the two-piece mold shell component 3; the two-piece mold shell component 3 is fixed by wrapping with a meltable adhesive tape.

[0063] The segmentation device 5 of the automatic separation device of the present invention moves the sampling probe along the Figure 1 The middle splitting device 5 divides the sampling probe into two parts, the probe tail area 1 and the probe sampling area 2, in a vertical direction of action. The dividing surface where the splitting device 5 is located in the vertical direction of action is located at the guide groove 6 of the flat cylindrical two-piece mold shell component 3 and is tangent to the outer circle of the cylinder formed when the two-piece mold shell component 3 is in a combined state. The action direction of the splitting device 5 is perpendicular to the end faces of the flat cylinder formed when the two-piece mold shell component 3 is combined. When the splitting device 5 acts, the paper shell of the sampling probe is squeezed and deformed, and the deformed opening shape is conducive to the two-piece mold shell component 3 and the sample 4 falling out.

[0064] The two-piece mold shell component 3 is fixed by wrapping it with a sinterable adhesive tape during assembly. When sampling, the adhesive tape is used to keep the two-piece mold shell component 3 in a combined state. After taking the sample 4, the sinterable adhesive tape is melted by the high-temperature metal, and the metal in the guide groove 6 and the two-piece mold shell component 3 solidifies into a solid state. Through the action of the dividing device 5, the handle-shaped metal formed by the sample 4 in the two-piece mold shell component 3 and the guide groove 6 will be broken and separated, and the sample 4 is a regular flat cylinder.

[0065] Please combine Figure 3 As shown, an automatic separation device for a sampling probe provided by the present invention comprises a splitting device 5 for cutting the sampling probe, and an inclined bottom plate located in front of the splitting device 5 .

[0066] The upper end of the inclined bottom plate is placed close to the dividing device 5 , and the lower end of the inclined bottom plate is placed obliquely downward toward the front of the dividing device 5 .

[0067] The inclined bottom plate includes a first inclined bottom plate 7 and a second inclined bottom plate 8 connected to the lower end of the first inclined bottom plate 7. In this embodiment, the first inclined bottom plate 7 and the second inclined bottom plate 8 are the same plate.

[0068] A first posture adjusting device 9, a first separating device 10, a second posture adjusting device 11 and a second separating device 12 are sequentially arranged between the upper end of the inclined bottom plate and the lower end of the inclined bottom plate.

[0069] After the sampling probe passes through the splitting device 5 , the probe sampling area 2 falls onto the first inclined bottom plate 7 , and the probe sampling area 2 changes from a horizontal state to a state of sliding down along the first inclined bottom plate 7 .

[0070] The first posture adjustment device 9 includes a constraint collision point 901 (in this embodiment, the constraint collision point 901 uses a slender rod), a flip collision point 902 (in this embodiment, the flip collision point 902 also uses a slender rod), a flip collision point 902, and a plurality of guide points 903 (in this embodiment, the guide point 903 uses a guide rod), which are arranged in sequence from the upper end of the inclined bottom plate to the lower end of the inclined bottom plate. All of them are installed on the upper surface of the first inclined bottom plate 7. The flip collision point 902 provides a flip collision point, and the constraint collision point 901 provides a constraint collision point. The end face of the sliding probe sampling area 2 collides with the flip collision point 902 (such as Figure 4 As shown), the side surface collides with the constraint collision point 901 and flips sideways, with the sample 4 and the opening side of the two-piece mold shell component 3 gradually facing downward, and is guided by the guide point 903 to fall into the first separation device 10.

[0071] The first separation device 10 includes a first side plate 1001 , a second side plate 1002 and a flap 1003 .

[0072] The first side plate 1001 and the second side plate 1002 are mounted on the upper surface of the first inclined bottom plate 7 to form a first chute 1005;

[0073] A drop opening 1004 is provided on the first side plate 1001 of the first chute 1005 and the first inclined bottom plate 7 below the second side plate 1002 . The flap 1003 is connected to the lower surface of the inclined bottom plate and is located at the drop opening 1004 . The size of the drop opening 1004 can pass through the probe sampling area 2 .

[0074] The lower outlet of the first chute 1005 is configured to be a gradually decreasing structure, and the minimum size of the lower outlet of the first chute 1005 is larger than the maximum size of the two-piece mold shell component 3 and smaller than the cross-sectional diameter size of the probe sampling area 2, so that the paper shell of the probe sampling area 2 and the two-piece mold shell component 3 inside it can be separated.

[0075] A drop opening 1004 is formed between the upper end of the first side plate 1001 and the upper end of the second side plate 1002, a first chute 1005 is formed between the lower end of the first side plate 1001 and the lower end of the second side plate 1002, and a flap 1003 is connected to the lower surface of the first inclined bottom plate 7 through an adjustable hinge 1006 and is located at the position of the drop opening 1004 (such as Figure 5 shown).

[0076] The probe sampling area 2 flipped sideways and gradually turned downwards with its opening side facing downwards rushed into the first chute 1005 due to inertia. At this time, there was no force between the probe sampling area 2 and the first inclined bottom plate 7, and the opening side of the probe sampling area 2 collided with the outlet below the first chute 1005, and the speed of the probe sampling area 2 dropped to zero, while the sample 4 and the two-piece mold shell component 3 in the probe sampling area 2 continued to rush out from the lower outlet of the first chute 1005. The paper shell part of the probe sampling area 2 caused a flap 1003 installed on the lower surface of the first inclined bottom plate 7 to flip downwards due to its own gravity, and passed through the drop port 1004, completing the separation between the paper shell part of the probe sampling area 2 and the sample 4 and the two-piece mold shell component 3.

[0077] The height of the first side plate 1001 and the second side plate 1002 must be at least greater than the cross-sectional radius of the probe sampling area 2 to prevent the probe sampling area 2 from directly rushing out of the first side plate 1001 and the second side plate 1002 due to inertia.

[0078] The second posture adjustment device 11 includes a second chute 1101, which is installed on the upper surface of the second inclined bottom plate 8 and is used to adjust the posture of the sample 4 and the two-piece mold shell component 3. The inner side wall of the second chute 1101 is set as a curved surface 1102 with a variable angle, and the inlet 1102 of the second chute 1101 is connected to the outlet of the first chute 1005. The sample 4 and the two-piece mold shell component 3 that slide out of the first chute 1005 are gradually adjusted from any posture to a nearly upright state through the second chute 1101 and enter the second separation device 12.

[0079] The second separation device 12 includes a third side plate 1201 and a fourth side plate 1202 with an inclined angle, and a third chute 1203 is formed between the third side plate 1201 and the fourth side plate 1202 .

[0080] The third side plate 1201 and the fourth side plate 1202 are connected to the upper surface of the second inclined bottom plate 8, the upper ends of the third side plate 1201 and the fourth side plate 1202 are both arranged toward the upper end of the inclined bottom plate, the lower ends of the third side plate 1201 and the fourth side plate 1202 are both arranged toward the lower end of the inclined bottom plate (the inclination angle gradually increases), and the opening between the lower ends of the third side plate 1201 and the fourth side plate 1202 gradually becomes larger.

[0081] The upper inlet of the third chute 1203 is connected to the outlet 1103 of the second chute 1101. The inlet opening size of the third chute 1203 should be larger than the height of the cylinder formed when the two-piece mold shell parts 3 are in the combined state, and smaller than the diameter of the cylinder formed when the two-piece mold shell parts 3 are in the combined state.

[0082] Sample 4 is a standard flat cylinder and is in an upright position when entering the second separation device 12. Sample 4 rolls and slides along a straight line in the third chute 1203 and is always located at the center line of the third chute 1203. Since the two-piece mold shell component 3 has a chamfer, it will gradually change from an upright position to a rolling and sliding position along the angle of the third side plate 1201 and the fourth side plate 1202 during the sliding in the third chute 1203. The rolling and sliding angle increases with the increase of the inclination angle of the third side plate 1201 and the fourth side plate 1202. Since the outlet of the third chute 1203 is also gradually enlarged, the two-piece mold shell component 3 will gradually deviate from the center line of the third chute 1203, and the distance between it and sample 4 will become larger and larger until separation, and sample 4 falls into the sample removal area 1204 located at the outlet of the third chute 1203.

[0083] Please combine Figure 4 As shown, the distance between the flip collision point provided by the flip collision point 902 and the constraint collision point provided by the constraint collision point 901 and the first inclined bottom plate 7 is not less than the end face radius of the probe sampling area 2; the axial section perpendicular to the first inclined bottom plate 7 divides the probe sampling area 2 into two areas, and the flip collision point and the constraint collision point should be located in the same area.

[0084] Please combine Figure 5 As shown, a downwardly flipping flap 1003 is installed on the lower surface of the first inclined bottom plate 7 at the drop-off opening 1004 through an adjustable hinge 1006. The probe sampling area 2 rushes into the first chute 1005 due to inertia and collides with the lower outlet of the first chute 1005, and the sample 4 and the two-piece mold shell component 3 slide out from the opening. The probe sampling area 2 flips the flap 1003 downward due to its own action, and the probe sampling area 2 falls out from the drop-off opening 1004, completing the separation between the paper shell part of the probe sampling area 2 and the sample 4 and the two-piece mold shell component 3. In addition to realizing the flipping of the flap 1003 through the adjustable hinge 1006, the opening and closing of the flap 1003 can also be controlled by a cylinder. In addition, since the probe sampling area 2 moves due to inertia before colliding with the outlet of the first chute 1005, there is no force between it and the first inclined bottom plate 7, so the flap 1003 can be omitted.

[0085] Please combine Figure 6 As shown, the inner wall of the second chute 1101 is configured to contain a curved surface 1102 with a changing angle, wherein the curved surface 1102 is parallel to the bottom plate 1104 of the second chute 1101 at the inlet 1103 of the second chute 1101 and is perpendicular to the bottom plate 1104 of the second chute 1101 at the outlet 1105 of the second chute 1101.

[0086] Please combine Figure 7As shown, it is a first embodiment of the third chute 1203, two partition plates 1205 are installed on the bottom plate at the outlet of the third chute 1203, and the sample extraction area 1204 is located below the outlet of the third chute 1203 and between the two partition plates 1205. The sample 4 rolls and slides along a straight line on the center line of the third chute 1203, slides into the channel between the two partition plates 1205 and falls into the sample extraction area 1204 below, and the two-piece mold shell component 3, due to the chamfer, rolls and slides against the third side plate 1201 and the fourth side plate 1202, slides into the channel between the partition plate 1205 and the third side plate 1201 and the fourth side plate 1202, and falls into the shell component collection area.

[0087] Please combine Figure 8 As shown, it is a second embodiment of the third chute 1203, a rectangular opening 1206 is provided at the center of the bottom plate at the outlet of the third chute 1203, a blocking plate 1207 is provided on the edge of the rectangular opening 1206 close to the sample extraction area 1204, and the sample extraction area 1204 is located below the rectangular opening 1206. The sample 4 rolls and slides along a straight line on the center line of the third chute 1203, and falls from the rectangular opening 1206 into the sample extraction area 1204 below, while the two-piece mold shell component 3, due to its chamfered corners, rolls and slides against the third side plate 1201 and the fourth side plate 1202, slides out at the outlet of the third chute 1203, and falls into the shell component collection area.

[0088] Please combine Fig. 9 As shown, the present invention also provides a method for using the automatic separation device, comprising the following steps:

[0089] 1) Since the relative positions of the sampling port 13 and the two-piece mold shell component 3 are fixed and known during the early assembly of the sampling probe, the appearance of the sampling probe is observed, and according to the position of the sampling port 13, the end surface of the flat cylinder formed by the two-piece mold shell component 3 in the combined state is kept perpendicular to the action direction of the dividing device 5, and then the sampling probe can be combined. Figure 1 As shown, the injection port 13 is placed in the horizontal direction;

[0090] 2) The splitting surface is located at the guide groove 6 of the flat cylindrical sample 4 and the two-piece mold shell component 3 and is tangent to the side of the cylinder formed when the two-piece mold shell component 3 is in a combined state. Taking the front end of the probe sampling area 2 as a reference, the distance between the front end surface of the probe sampling area 2 and the tangent surface is measured to be 91 mm, and the positional relationship between the front end surface of the probe sampling area 2 and the splitting device 5 is adjusted to be 91 mm apart. The position of the probe sampling area 2 after adjustment is marked and recorded on the splitting device 5, so that the probe sampling area 2 in subsequent tests is split at the same position;

[0091] 3) According to the position where the probe sampling area 2 is segmented on the segmentation device 5, the installation positions of the constraint collision point 901, the flip collision point 902 and the guide point 903 on the upper surface of the first inclined bottom plate 7 are preliminarily determined. The flip collision point 902 is located at the end of the probe sampling area 2, the constraint collision point 901 is located at the side of the probe sampling area 2, and the distances between the constraint collision point 901, the flip collision point 902 and the first inclined bottom plate 7 are not less than the end surface radius of the probe sampling area 2;

[0092] 4) Adjust the angle of the first inclined bottom plate 7 to be 30° with the horizontal direction, and keep the initial angle of the second inclined bottom plate 8 consistent with that of the first inclined bottom plate 7, so that the flap 1003 on the lower surface of the first inclined bottom plate 7 is in a closed state;

[0093] 5) The segmentation device 5 segments the sampling probe, repeats the test multiple times, and adjusts the first segmentation device 10, the second posture adjustment device 11, and the second segmentation device 12;

[0094] 6) After completing the adjustment steps in step 5), the automatic separation equipment can be put into production.

[0095] The adjustment in step 5) specifically includes the following steps:

[0096] 5.1) Observe the flipping posture of the probe sampling area 2, and fine-tune the constraint collision point 901 so that the constraint collision point is located on the side of the probe sampling area 2. According to the collision position of the probe sampling area 2 and the first chute 1005, fine-tune the position of the flipping collision point 902. If the collision position of the probe sampling area 2 and the first chute 1005 is located on the first side plate 1001 of the first separation device 10, fine-tune the flipping collision point to the right; if the collision position of the probe sampling area 2 and the first chute 1005 is located on the second side plate 1002 of the first separation device 10, fine-tune the flipping collision point to the left. After multiple tests, the collision position of the probe sampling area 2 and the first chute 1005 is located at the lower exit of the first chute 1005;

[0097] 5.2) Then, the flap 1003 on the lower surface of the first inclined bottom plate 7 is turned over to observe whether the sample 4 and the two-piece mold shell component 3 can be separated from the probe sampling area 2 smoothly. If the probe sampling area 2 has fallen out of the drop opening 1004 before the sample 4 and the two-piece mold shell component 3 slide out and separate from the probe sampling area 2, the inclination angle of the first inclined bottom plate 7 is increased to provide sufficient momentum for the probe sampling area 2 until the sample 4 and the two-piece mold shell component 3 slide out of the probe sampling area 2 and the paper shell of the probe sampling area 2 falls off;

[0098] 5.3) Observe the movement state of the sample 4 and the two-piece mold shell component 3 in the third chute 1203 of the second posture adjustment device 11 and the second separation device 12. If the speed of the sample 4 and the two-piece mold shell component 3 in the third chute 1203 drops to zero and they are stuck in the third chute 1203 and cannot slide out smoothly, increase the inclination angle of the second inclined bottom plate 8; if the sample 4 and the two-piece mold shell component 3 pass through the second posture adjustment device 11 too fast and directly break away from the third chute 1203 and rush out, reduce the inclination angle of the second inclined bottom plate 8 until the sample 4 and the two-piece mold shell component 3 are successfully separated from the outlet of the third chute 1203.
