Abstract
Description
Technical Field
[0001] This utility model relates to the field of materials processing technology, and specifically discloses a sampling device for refractory material production. Background Technology
[0002] Refractory material processing encompasses raw material crushing, screening and purification. After precise batching, mixing and homogenization, the raw materials are formed into billets using molding processes such as pressing, casting, extrusion or isostatic pressing. The billets need to be dried to remove moisture and then fired in a high-temperature kiln to achieve mineral phase transformation and sintering densification.
[0003] During the sampling process of refractory materials, since some refractory materials are cylindrical or have a certain curvature, it is easy to damage the sample if traditional clamps are used to forcibly clamp the sample. At the same time, due to the depth and temperature of the production equipment, the electronic telescopic rod is easily damaged during use. Therefore, a sampling device for refractory material production is needed to solve this problem. Utility Model Content

Then the outer protective tube is pulled out, achieving the purpose of sampling without squeezing or clamping, and solving the problem of difficult sampling of cylindrical samples.

[0012] The beneficial effects of this utility model are:
[0013] 1. This sampling device for refractory material production inserts a storage tray into the sample hole, and the pull-back blocks on both sides are squeezed into the storage tray by the inner wall of the sample. When the storage tray slides out of the sample, the spring rod pushes the pull-back blocks on both sides to pop out of the device, so that the flat surface of the pull-back blocks is in close contact with the back side of the sample.

[0024] In this embodiment: the outer protective tube 1 is used to fix the position of part of the device and provide the necessary working environment for part of the device.
[0025] As a technical optimization of this utility model, the auxiliary rotating structure includes a connecting frame 5 and an anti-slip grip 6. An anchoring column 4 is fixedly connected to the inner surface of the connecting frame 5, and the anti-slip grip 6 is fixedly connected to the inner surface of the connecting frame 5.
[0026] In this embodiment: the auxiliary rotating structure is used to drive the outer disk 3 to rotate.
[0027] As a technical optimization of this utility model, the push-rotating block 10 is a circular cylinder, and four rounded corner protrusions are equidistantly provided on the outer circumference of the push-rotating block 10. An extension tube 11 is slidably connected to the outer surface of the rounded corner protrusions.
[0028] In this embodiment: the push-rotating block 10 is used to push the extension tube 11 to rotate through its own rounded corner protrusion during its own rotation.
[0029] As a technical optimization of this utility model, the extension tube 11 is a circular tube, the outer circumferential surface of the extension tube 11 is provided with a threaded groove, and the inner wall of the extension tube 11 is provided with four equidistant rounded corner grooves, the rounded corner grooves being the same length as the circular tube.
[0030] In this embodiment: the extension tube 11 is used to extend the overall length of the device, and at the same time drive the storage tray 12 to move into the container.
[0031] As a technical optimization of this utility model, the wrapping spring rod 14 is a circular rod, and a spring is slidably connected to the outer circumference of the wrapping spring rod 14. One end of the spring is fixedly connected to the partition plate 13, and the other end of the spring is fixedly connected to the pull-back block 15.
[0032] In this embodiment: the spring rod 14 is used to limit the movement distance of the pull-back block 15 and push the pull-back block 15 outward.
[0033] As a technical optimization of this utility model, the pull-back block 15 is a trapezoidal block, the outer surface of the pull-back block 15 away from the outer protective tube 1 is an inclined surface, the angle between the inclined surface of the pull-back block 15 and the slot of the pull-back block 15 is 20 degrees, and the angle formed by the inclined surface of the pull-back block 15 and the straight edge of the pull-back block 15 is a rounded corner.

[0035] The working principle and usage process of this utility model are as follows: When using the device, select a pull-back block 15 of appropriate length according to the sample gap size. Then, hold the heat insulation sleeve 2 and insert the outer protective tube 1 into the production device. Next, rotate the anti-slip handle 6 according to the sample distance. This causes the anti-slip handle 6 to drive the hollow tube 9 to rotate via the connecting frame 5. This, in turn, causes the hollow tube 9 to drive the push-rotating block 10 to rotate, which in turn pushes the extension tube 11 to rotate. Thus, during the rotation of the extension tube 11, its threaded groove is fixed in position to the outer protective tube 1. The threaded grooves on the inner wall push the extension tube 11 into the production device. Then, the extension tube 11, along with the storage tray 12, is inserted into the sample hole. After the storage tray 12 is inserted into the sample hole, the pull-back blocks 15 on both sides are squeezed into the storage tray 12 by the inner wall of the sample. When the storage tray 12 slides out of the sample, the spring rod 14 pushes the pull-back blocks 15 on both sides to pop out of the device, so that the flat surface of the pull-back blocks 15 is in close contact with the back side of the sample. Then, the outer protective tube 1 is pulled out, so that the sample is gradually pulled out of the production device through the pull-back blocks 15, thereby completing the sampling.
