The connecting shaft 160 is coaxially connected to the linkage disk 120 and the transfer bin 110 in sequence. The feeding tube 130 and the connecting shaft 160 are coaxially arranged and the bottom thereof passes through the test box 100 and is connected to the top of the transfer chamber 110. The bottom of the outer wall of the transfer chamber 110 is hinged with three rotating tubes 170 that can rotate along a vertical plane. The rotating tubes 170 are rotatably connected to the transfer chamber 110 along a vertical plane through a rotating shaft. The three rotating tubes 170 are arranged at intervals along the circumference of the transfer chamber 110. The transfer chamber 110 is provided with three transfer chambers 180 whose tops are respectively connected to the feeding tubes 130. The three transfer chambers 180 are arranged at intervals along the circumference of the transfer chamber 110. The circumferential arrangement of the bin 110 is spaced apart, and the three transfer chambers 180 are respectively connected to the three rotating tubes 170 through the metal hose 190; the sample tube 140 is detachably connected to the rotating tube 170 so that the rotating tube 170 and the sample tube 140 are connected, and each rotating tube 170 is connected to a connecting pin 230, and the sample tube 140 is provided with a first connecting hole 240, and the rotating tube 170 is provided with a second connecting hole 250 corresponding to the first connecting hole 240, and the sample tube 140 can be slidably inserted into the rotating tube 170 so that the first connecting hole 240 is connected to the rotating tube 170. The connecting hole 240 and the second connecting hole 250 are aligned, and the connecting pin 230 is used to pass through or out of the corresponding first connecting hole 240 and the second connecting hole 250 in sequence. Each sample tube 140 is provided with a sleeve 260 that can be inserted or pulled out; a detachable connecting sleeve 210 is provided on the sample tube 140, and the connecting sleeve 210 is hinged to the linkage disk 120 through a connecting rod 200 that can rotate along a vertical plane. The connecting sleeve 210 is connected to a locking bolt 220 that can move axially to press or stop pressing the outer wall of the sample tube 140.

[0031] The present application also provides a method for preparing a sample for testing the bonding strength between a refractory repair material and a matrix, which comprises the following steps:

[0032] Open the test chamber 100, pull out the connecting pin 230, and then remove the sample tube 140 from the corresponding rotating tube 170. Remove the sleeve 260 from the sample tube 140, place the cylindrical matrix material test block in the sleeve 260, and reinsert it into the sample tube 140. Then, insert the sample tube 140 into the corresponding rotating tube 170, aligning the first connecting hole 240 and the second connecting hole 250 on the rotating tube 170 and the sample tube 140. Insert the connecting pin 230 through the corresponding first connecting hole 240 and the second connecting hole 250 in sequence to securely connect the rotating tube 170 and the sample tube 140.

[0033] The refractory repair material and water are uniformly stirred to obtain a refractory repair material slurry, and the refractory repair material slurry is fed into each transfer cavity 180 of the transfer bin 110 through the feeding pipe 130. The refractory repair material slurry passes through each transfer cavity 180 and the metal hose 190 and enters each rotating tube 170, and finally enters the sleeve 260 of the sample tube 140, so that the refractory repair material slurry in the sleeve 260 is mixed with the matrix material test block;

[0034] The drive motor 150 is controlled to start and drive the transfer chamber 110 and the linkage disk 120 to rotate for 5 minutes via the connecting shaft 160. The transfer chamber 110 and the linkage disk 120 drive the connected rotating tube 170 and the connecting rod 200 to rotate about the vertical axis. The high-speed centrifugal force causes the refractory repair material slurry and the matrix material test block in the sleeve 260 to be tightly combined. At this time, the connecting rod 200 drives the connecting sleeve 210 and the sample tube 140 and the rotating tube 170 mounted thereon to rotate relative to the vertical plane, further improving the degree of combination of the refractory repair material slurry and the matrix material test block. The drive motor 150 is then turned off and allowed to stand until the combined refractory repair material slurry and matrix material test block solidify.

[0035] After pulling out the connecting pin 230, the sample tube 140 is pulled out from the corresponding rotating tube 170, and the sleeve 260 is removed from the sample tube 140. The refractory repair material and the matrix material test block tightly combined in the sleeve 260 are taken out, and subsequent tensile, flexural or shear tests are performed to determine the bonding strength between the refractory repair material and the matrix material.

[0036] The sample preparation device and preparation method for the bonding strength between refractory repair material and matrix provided in the embodiment of the present application use the sleeve 260 in the sample tube 140 to accommodate the matrix material test block, and use the feeding pipe 130 to pass the refractory repair material slurry into the sleeve 260 of the sample tube 140 through the transfer cavity 180, the metal hose 190, and the rotating tube 170 in the transfer bin 110 to mix with the matrix material test block, and use the driving motor 150 to drive the transfer bin 110 and the linkage disk 120 to rotate, so that the sleeve 260 in the sample tube 140 rotates around the vertical axis and along the vertical plane at the same time, so that the refractory repair material slurry in the sleeve 260 and the matrix material test block are mixed and tightly combined to form an integrated sample, so that the bonding strength between the refractory repair material and the matrix material is closer to actual production, thereby improving the accuracy of the test data.

[0037] Each sample tube 140 is provided with an insertable or removable sleeve 260, which allows the user to easily separate the sleeve 260 from the sample tube 140, thereby taking out the refractory repair material slurry and matrix material prepared in the sleeve 260 in combination with the test block for testing.

[0038] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
