Description

[Technical field]

[0001] Technical Field The present invention relates to the technical field of metallurgy, in particular to a sampling probe and an automatic separation device thereof, as well as a method of use. [Background technology]

[0002] background In metallurgical production, it is necessary to determine the type and amount of additives and the end point of smelting according to the temperature, carbon content and other chemical compositions of the molten metal in the molten pool. In order to accurately obtain the contents of these chemical compositions, it is necessary to take samples and send them to a laboratory for analysis by a pneumatic sample delivery device. At present, the smelting area is mainly measured by attaching a composite probe for temperature measurement and sampling to a temperature measurement gun, and then manually inserting the temperature measurement gun into the smelting liquid. As for the separation operation of the probe sample after sampling, manual is usually adopted in the prior art, thus limiting the overall automation level of the smelting area.

[0003] The outside of the currently used sampling probe consists of a tubular paper housing, and the inside of the probe has various configurations according to different metal sample mould boxes. One of the more common configurations is a cylindrical flat sample, and the housing of the mould box for the sample is of a two-piece construction, which is fixed together by a metal clamp. This metal clamp is used to ensure that the two-piece mould box housing is always held together during the process in which the sampled molten metal is solidified, so that the resulting solidified sample of the molten metal is a uniform cylinder without burrs on the edges.

[0004] Chinese patent CN203545142U discloses a device for automatically exposing a sample, in which a probe is first fixed on its outer surface by a support device, a probe with a sample is dispensed by a dispensing device, and a sample with a housing is expelled from the dispensed area of ​​the probe by a punch. The housing and the packing material containing the sample are introduced into the housing removal device through an introduction device, in which the housing includes a clamp for holding the sample housing closed during sampling. The housing removal device includes a bottom plate, a vibration motor, a centrifugal device, an impact body, etc. The bottom plate is inclined downward, and a vibration motor is provided on the bottom surface of the bottom plate. Vibration of the bottom plate moves the sample toward the centrifugal device in the housing removal device. The gap under the centrifugal device is large enough for the separated sample and housing to pass through, and the unseparated sample and housing get an impact toward the impact body by the centrifugal device. Due to the impact of the impact body, the object is usually decomposed. The decomposed sample, housing and packing material move toward the sample extraction area through the gap under the centrifugal device. Before reaching the sample extraction area, the decomposed sample, the housing and the filler are blocked by a blocking layer on which the channels for the housing and the filler are arranged, so that the housing and the filler are separated through the channel, and the sample cannot pass through the channel due to its size, so that the sample is guided by the blocking layer and finally enters the sample extraction area. The device has multiple operating mechanisms, a complex structure, high cost, extensive post-maintenance work, and it is difficult to guarantee reliability. The method of allowing the housing parts with clamps to collide with the impact body by the centrifugal device can only ensure that the sample is separated from the housing in most cases, it is difficult to deal with the situation where the clamp is attached too tightly, and it is difficult to separate the sample from the housing.Furthermore, the device has no constraint on the orientation of each part, so that any orientation of the parts easily causes clogging in the gap between the centrifugal device and the bottom plate.

Alternatively, the distance between the third side plate and the fourth side plate at the entrance of the third chute is greater than the height of the cylinder that would be formed when the two-piece mold housing parts are in a combined state and less than the diameter of the cylinder that would be formed when the two-piece mold housing parts are in a combined state, thereby guiding the two-piece mold housing parts to roll along the side of the cylinder.

[0020] Preferably, the inversion plate is connected to the underside of the tilted bottom plate by an adjustable hinge.

[0021] Preferably, the third chute is further provided with a partition plate at its lower end (or tail).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] Detailed Description In order to make the above technical solution of the present invention better understandable, the technical solution of the present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0031] 1 and 2, the sampling probe provided by the present invention includes a probe tail region 1 and a probe sampling region 2 connected to the upper end of the probe tail region 1; the probe sampling region 2 includes a paper housing, a two-piece mold housing part 3 disposed in the paper housing, and a sample 4 disposed in the two-piece mold housing part 3; the two-piece mold housing part 3 is wrapped and fixed by an adhesive tape that can be burned and melted.

[0032] In the automatic separation device of the present invention, the cutting device 5 places the sampling probe whose sampling has been completed in a direction perpendicular to the operating direction of the cutting device 5 in Fig. 1, and cuts the sampling probe into two parts, namely the probe tail region 1 and the probe sampling region 2. The cutting surface formed by the operating direction of the cutting device 5 is located in the guide channel 6 of the flat cylinder and the two-piece mold housing part 3, and is tangent to the cylindrical side formed when the two-piece mold housing part 3 is in a combined state. The function of the cutting device 5 is to extrude and deform the paper housing of the sampling probe, and the deformed opening shape is favorable for the two-piece mold housing part 3, and the sample 4 goes out.

[0033] The two-piece mold housing part 3 is wound and fixed by an adhesive tape that can be burned and melted during assembly, and during sampling, the two-piece mold housing part 3 is kept in a bonded state under the action of the adhesive tape that can be burned and melted; after the sample 4 is taken, the adhesive tape that can be burned and melted is burned and melted by the molten metal, and then the molten metal entering the two-piece mold housing part 3 through the guide channel 6 is solidified into a solid state. Through the action of the cutting device 5, the sample 4 in the two-piece mold housing part 3 and the shank-shaped metal formed by the hot metal flowing through the guide channel 6 are broken and separated, and the sample 4 is a uniform flat cylinder.

[0034] As shown in FIG. 3, the sampling probe automatic separation device provided by the present invention includes a cutting device 5 for cutting the sampling probe, and a slanted bottom plate located downstream of the cutting device 5.

[0035] The inclined bottom plate slopes downward from the front end to the rear end, with the upper end (i.e., the front end) of the inclined bottom plate being located close to the cutting device 5; the lower end (i.e., the rear end) of the inclined bottom plate being farther away from the cutting device 5 and lower than the horizontal plane on which the front end is located.

[0036] Preferably, the downward inclination angle of the inclined bottom plate is 30°, ie the inclination angle between the inclined bottom plate and the horizontal plane is 30°.

[0037] In some embodiments, the sloped bottom plate may include a first sloped bottom plate 7 and a second sloped bottom plate 8 connected to the bottom end (or rear end) of the first sloped bottom plate 7. In this embodiment, the first sloped bottom plate 7 and the second sloped bottom plate 8 are the same plate.

[0038] A first alignment device 9, a first separation device 10, a second alignment device 11 and a second separation device 12 are arranged in succession between the upper end of the sloping-bottom plate and the lower end of the sloping-bottom plate.

[0039] After the sampling probe is cut by the cutting 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 sliding state along the first inclined bottom plate 7.

[0040] The first position adjustment device 9 includes a constrained collision point 901 (the constrained collision point 901 in this embodiment is an elongated rod), a reversing collision point 902 (the reversing collision point 902 in this embodiment is also an elongated rod) and a number of guide points 903 (the guide point 903 in this embodiment is a guide rod, i.e., an elongated rod, which can play the role of guiding according to a set position), which are arranged in order from the upper end of the inclined bottom plate to the lower end of the inclined bottom plate, and all are installed on the upper surface of the first inclined bottom plate 7. In this embodiment, the reversing collision point 902 provides one reversing collision point, and the constrained collision point 901 provides one constrained collision point, but the present application does not limit the number of the reversing collision points and the constrained collision points. The sliding end face of the probe sampling area 2 collides with the inversion collision point 902 (as shown in FIG. 4), and the side of the probe sampling area 2 collides with the restraining collision point 901 and then rolls over, so that the open side of the two-piece mold housing part 3 with the sample 4 gradually faces downward and falls into the first separation device 10, guided by the guide point 903.

[0041] The first separation device 10 includes a first side plate 1001 , a second side plate 1002 and an inversion plate 1003 .

[0042] The first side plate 1001 and the second side plate 1002 are installed on the upper surface of the first inclined bottom plate 7, thereby forming a first chute 1005; below the first side plate 1001 and the second side plate 1002, a drop opening 1004 is provided in the first inclined bottom plate 7 where the first chute 1005 is located, the inverted plate 1003 is connected to the lower surface of the inclined bottom plate and covers the drop opening 1004, and the size of the drop opening 1004 ensures that the probe sampling area 2 passes through smoothly.

[0043] The first chute 1005 is arranged in a gradually decreasing structure such that the minimum size of the outlet at the bottom of the first chute 1005 is larger than the maximum size of the two-piece mold housing part 3 and smaller than the cross-sectional diameter of the probe sampling area 2, thereby separating the paper housing of the probe sampling area 2 from the two-piece mold housing part 3 inside the paper housing.

[0044] A drop opening 1004 is formed between the first side plate 1001 and the second side plate 1002, and an outlet of the 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. The inverted plate 1003 is connected to the lower surface of the first sloping bottom plate 7 by an adjustable hinge 1006 and can cover the location of the drop opening 1004 (as shown in FIG. 5 ).

[0045] The probe sampling area 2 gradually turns sideways so that the open side faces downward, and due to inertia, it rushes into the first chute 1005, and at this moment, there is no force between the probe sampling area 2 and the first inclined bottom plate 7. The open side of the probe sampling area 2 collides with the side plate at the bottom of the first chute 1005 at the outlet, and the probe sampling area 2 is blocked in the first chute because its size cannot pass through the outlet of the first chute 1005; the probe sampling area 2 and the sample 4 in the two-piece mold housing part 3 can then continue to fly out from the outlet at the bottom of the first chute 1005. The paper housing of the probe sampling area 2 allows the inversion plate 1003 installed on the lower surface of the first inclined bottom plate 7 to flip downward due to its own gravitational effect, and passes through the drop opening 1004 and goes out of the separation device, so that the separation of the paper housing of the probe sampling area 2 from the sample 4 and the two-piece mold housing part 3 is completed.

[0046] The height of the first side plate 1001 and the second side plate 1002 should be at least greater than the cross-sectional radius of the probe sampling area 2 to prevent the probe sampling area 2 from tipping directly out of the first side plate 1001 and the second side plate 1002 due to inertia.

[0047] The second position adjustment device 11 includes a second chute 1101 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 housing part 3. The inner wall of the second chute 1101 is arranged as a curved surface 1102 with various angles, and the inlet 1103 of the second chute 1101 communicates with the outlet of the first chute 1005. The sample 4 and the two-piece mold housing part 3 sliding down from the first chute 1005 pass through the second chute 1101, are gradually adjusted from any posture to an almost upright state, i.e., a state rolling along the side of the mold housing part 3, and enter the second separation device 12.

[0048] The second separating device 12 includes a third side plate 1201 having an inclined angle and a fourth side plate 1202 having an inclined angle, and a third chute 1203 is formed between the third side plate 1201 and the fourth side plate 1202.

[0049] 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 arranged to face the upper end of the inclined bottom plate, and the lower ends of the third side plate 1201 and the fourth side plate 1202 are arranged to face the lower end of the inclined bottom plate. The third side plate and the fourth side plate are gradually turned outward in the direction from the front end to the rear end of the inclined bottom plate (or the inclination angle of the third side plate and the fourth side plate is gradually increased in the opposite direction). The distance between the third side plate 1201 and the fourth side plate 1202 is gradually increased from the front end to the rear end.

[0050] The inlet of the third chute 1203 communicates with the outlet 1105 of the second chute 1101, and the size of the inlet of the third chute 1203 should be larger than the height of the cylinder that is formed when the two-piece mold housing part 3 is in a combined state and smaller than the diameter of the cylinder that is formed when the two-piece mold housing part 3 is in a combined state.

[0051] The sample 4 is a standard flat cylinder, which is in an upright state when it enters the second separation device 12, then rolls and slides down along a straight line in the third chute 1203, and always stays at the centerline of the third chute 1203, while the two-piece mold housing part 3, due to its chamfered surface, gradually changes from an upright state to a rolling state along the third side plate 1201 and the fourth side plate 1202 while sliding down. Because the outward inclination angle of the third side plate 1201 and the fourth side plate 1202 gradually increases, and because the third chute 1203 gradually widens from the front end to the rear end, the two-piece mold housing part 3 gradually moves out of the centerline of the third chute 1203, and the distance between the two-piece mold housing part 3 and the sample 4 gradually increases until the two-piece mold housing part 3 and the sample 4 are completely separated, and then the sample 4 falls into the sample extraction area 1204 located at the outlet of the third chute 1203.

[0052] Referring again to FIG. 4, the distance between the inverted collision point provided by inverted collision point 902 and the restraint collision point provided by restraint collision point 901 and the first sloping bottom plate 7 is not smaller than the radius of the end face of the probe sampling area 2; if the probe sampling area 2 is divided into left and right areas with respect to an axial cross section perpendicular to the first sloping bottom plate 7 as shown in FIG. 4, the inverted collision point and the restraint collision position should be located in the same area.

[0053] 5 again, the lower surface of the first inclined bottom plate 7 is provided with an inverted plate 1003 which is turned down at the drop opening 1004 by an adjustable hinge 1006. The probe sampling area 2 which rushes into the first chute 1005 by inertia hits the outlet at the bottom of the first chute 1005. The sample 4 and the two-piece mold housing part 3 slide into the second chute from the outlet, and the paper housing of the probe sampling area 2 can turn the inverted plate 1003 down by its own gravity, thereby dropping from the drop opening 1004 to complete the separation of the paper housing of the probe sampling area 2 from the sample 4 and the two-piece mold housing part 3. In addition to realizing the turning over of the inverted plate 1003 by the adjustable hinge 1006, the opening and closing of the inverted plate 1003 can be controlled by an air cylinder. Moreover, the probe sampling area 2 does not fall from the drop opening 1004 due to its own inertia. This is because there is no force acting between the probe sampling area 2 and the first sloped bottom plate 7 before the probe sampling area 2 impacts the outlet of the first chute 1005. As a result, in some embodiments the inverted plate 1003 may be omitted.

[0054] Referring to FIG. 6, the inner wall of the second chute 1101 is set as a curved surface 1102 having various angles, and 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 the curved surface 1102 is perpendicular to the bottom plate 1104 of the second chute 1101 at the outlet 1105 of the second chute 1101.

[0055] 7, a first embodiment of the third chute 1203 is now shown. Two partition plates 1205 are installed on the inclined bottom plate at the exit position of the third chute 1203. The sample extraction area 1204 is located at the end of the exit position of the third chute 1203 and is located between the two partition plates 1205. The sample 4 rolls and slides down 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, while the two-piece mold housing part 3, due to its chamfered surface, does not roll 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 channel between the partition plate 1205 and the fourth side plate 1202, and falls into the mold housing part area.

[0056] 8, a second embodiment of the third chute 1203 is now shown. A rectangular opening 1206 is provided at the centerline of the inclined bottom plate at the exit location of the third chute 1203. A blocking plate 1207 is provided at the edge of the rectangular opening 1206 adjacent to the sample extraction area 1204 (i.e., at the end of the rectangular opening). The sample extraction area 1204 is located below the rectangular opening 1206. The sample 4 rolls and slides down along a straight line on the centerline of the third chute 1203 and falls from the rectangular opening 1206 to the sample extraction area 1204 below, while the two-piece mold housing part 3, due to its chamfered surface, does not roll against the third side plate 1201 and the fourth side plate 1202, but slides down from the exit of the third chute 1203 and falls into the housing part collection area.
