DETAILED DESCRIPTION

[0034] The following will be described in detail in combination with the accompanying Figures 1-4 The present application will be further described in detail.

[0035] The embodiment of the present application discloses a sampling device for directional solidification furnace.

[0036] The sampling device for directional solidification furnace comprises a frame body 7, sampling cylinders 1, mounting seats 2, connecting frames 3 and collecting grooves 4. The frame body 7 is fixedly installed near the directional solidification furnace to provide stable support for the whole device. Meanwhile, the frame body 7 is disc-shaped, and a plurality of sampling cylinders 1 are evenly distributed along the axial direction of the frame body 7. The sampling cylinders 1 are fixedly installed on the frame body 7, and the side walls of the sampling cylinders 1 are provided with feeding ports, and the bottoms of the sampling cylinders 1 are provided with discharging ports. The discharging ports of the sampling cylinders 1 are provided with sealing plates, and the sealing plates are provided with connecting rods. The connecting rods are moved by a power assembly. The mounting seats 2 are provided with mounting holes, and the mounting holes are sleeved on the sampling cylinders 1 and are fixedly connected with the sampling cylinders 1. The connecting frames 3 are installed on the mounting seats 2 and are in sliding fit with the mounting seats 2, and the connecting frames 3 are relatively slid by a pulling driving unit 6. Meanwhile, the connecting frames 3 are in rotary fit with the mounting seats 2, and the connecting frames 3 are relatively rotated with the mounting seats 2 around a specific axis by a rotary driving unit 5. The collecting grooves 4 are installed on the connecting frames 3 and are used for collecting the metal liquid dropped from the sampling cylinders 1.

[0037] In the sampling process, first, the bottom end of the sampling cylinder 1 is placed in the metal liquid of the directional solidification furnace, and then the metal liquid flows into the sampling cylinder 1 from the feeding port of the sampling cylinder 1 to collect the metal liquid. After sampling is completed, the sampling cylinder 1 is moved to directly above the directional solidification furnace, the rotary driving unit 5 makes the collecting groove 4 be directly below the sampling cylinder 1 through the connecting frame 3, and the pulling driving unit 6 again makes the groove of the collecting groove 4 be close to the sampling cylinder 1 through the connecting frame 3. The metal liquid drops along the cylinder wall of the sampling cylinder 1 to the collecting groove 4 for collection, thereby reducing the possibility of the metal liquid dropping to the working area.

[0038] In order to improve the operation convenience of the device, the side wall of the mounting seat 2 is provided with an arc-shaped guide groove 21. The rotary driving unit 5 comprises double-end rotary actuators 51, transmission frames 52 and clamping pieces 53. The double-end rotary actuators 51 are installed on the mounting seat 2, and the push rod axes thereof pass through the arc centers of the guide grooves 21. The transmission frames 52 are provided with two, and each transmission frame 52 is installed on the push rod of the corresponding double-end rotary actuator 51. The clamping pieces 53 are provided with two, are installed on the corresponding transmission frames 52, are moved in the guide grooves 21 through the transmission frames 52, and clamp the connecting frames 3. In this embodiment, the double-end rotary actuators 51 are double-head rotary cylinders.

[0039] The clamping piece 53 comprises a sliding column 531 and a clamping wheel 532. The sliding column 531 is arranged on the transmission frame 52, and the clamping wheel 532 is arranged on the sliding column 531 and is in abutment and rotation with the sliding column 531 and is in rolling cooperation with the connecting frame 3. When the connecting frame 3 is driven, the double-head rotary cylinder moves inside the guide groove 21 through the sliding column 531 of the transmission frame 52, and the two sliding columns 531 push the connecting frame 3 to rotate through the cooperation of the corresponding clamping wheels 532, so that the connecting frame 3 drives the collecting groove 4 to rotate, improving the convenience of lifting the collecting groove 4 to collect the metal liquid. The rolling cooperation of the clamping wheel 532 and the connecting frame 3 further reduces the friction and improves the convenience of rotating the connecting frame 3.

[0040] A waist groove 22 is further arranged on the side wall of the mounting seat 2, and the connecting frame 3 comprises a limiting column 31 and a connecting rod 32. The limiting column 31 is in sliding and rotation cooperation with the waist groove 22, and the connecting rod 32 is arranged on the limiting column 31, and the collecting groove 4 is arranged on the connecting rod 32. The pulling driving unit 6 comprises a telescopic column 61 and a guide ring 62. The telescopic column 61 is arranged on the mounting seat 2, and the telescopic direction is consistent with the length direction of the waist groove 22; the guide ring 62 is arranged on the push rod of the telescopic column 61 and is sleeved on the limiting column 31 in rotation cooperation. In this embodiment, the telescopic column 61 is a telescopic cylinder.

[0041] After the collecting groove 4 is rotated to below the sampling cylinder 1, the telescopic column 61 drives the limiting column 31 to move inside the waist groove 22 through the guide ring 62, and the inner wall of the waist groove 22 guides the limiting column 31, improving the accuracy of the moving direction. The limiting column 31 drives the collecting groove 4 to further approach the sampling cylinder 1 through the connecting rod 32, reducing the possibility of metal liquid droplets on the cylinder wall of the sampling cylinder 1 falling to the working area. When it is needed to drive the connecting rod 32 to rotate the collecting groove 4, the telescopic column 61 drives the limiting column 31 to move away from the telescopic column 61 inside the waist groove 22 through the guide ring 62, increasing the distance between the collecting groove 4 and the sampling cylinder 1, and facilitating the rotation of the collecting groove 4 driven by the connecting rod 32. This design not only improves the sampling efficiency, but also ensures the safety of the operation process.

[0042] The implementation principle of the sampling device for directional solidification furnace in the embodiment of the present application is as follows: when the metal liquid of the directional solidification furnace is sampled, the bottom end of the sampling cylinder 1 is placed in the directional solidification furnace, and the metal liquid enters the inside of the sampling cylinder 1 from the feeding port of the sampling cylinder 1. After sampling is completed, the sampling cylinder 1 is moved above the furnace, and the rotating and pulling driving unit 6 is cooperated to accurately position the collecting groove 4 below the sampling cylinder 1 and close to the cylinder wall, so that the metal liquid falls into the groove, reducing the risk of splashing. The design of the double-head rotary cylinder and the clamping wheel 532 reduces the friction and improves the convenience of rotation. When it is needed to rotate the collecting groove 4, the cooperation of the telescopic column 61 and the guide ring 62 makes the limiting column 31 move inside the waist groove 22, adjusts the distance between the collecting groove 4 and the sampling cylinder 1, ensures smooth rotation, and further improves the safety and efficiency of the sampling process.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, and thus: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
