Technical Field

[0001] The utility model relates to the technical field of slag viscosity detection, in particular to a material holding tool for measuring the viscosity of blast furnace slag. Background Art

[0002] At present, the viscosity of blast furnace slag is tested by a special slag viscosity measuring device, and the staff infers the condition of the ore before entering the blast furnace based on the slag viscosity, providing a basis for artificially adjusting the raw material ratio.

[0003] In the related art, a Chinese patent with authorization announcement number CN110108597B provides a multifunctional high-temperature silicon-molybdenum rod furnace tube viscosity determination system and method, which includes a lifting bracket and a silicon-molybdenum rod furnace, a corundum furnace tube is arranged in the silicon-molybdenum rod furnace, a crucible base is arranged at the bottom of the corundum furnace tube, a graphite crucible and a sample are placed on the crucible base, a graphite probe is arranged in the graphite crucible, and a lifting motor is arranged on the lifting bracket, and the lifting motor is used to control the depth of the graphite probe inserted into the graphite crucible. The slag is placed in the graphite crucible, and then the graphite crucible is placed on the crucible base in the corundum furnace tube through the crucible clamp. After the sample is melted and kept at a constant temperature for a period of time, the graphite probe is inserted into the melted sample and rotated to obtain the viscosity of the slag. After the slag viscosity is detected, the graphite crucible is taken out from the corundum furnace tube through the crucible clamp.

[0004] In the process of realizing the present application, the inventors found that there are at least the following problems in the technology: when the graphite crucible is taken and placed by means of crucible tongs, the crucible tongs are connected to the graphite crucible by abutting against the inner wall of the graphite crucible. However, since the inner wall of the graphite crucible is smooth, the graphite crucible is easy to fall when the crucible tongs drive the graphite crucible to move, thereby causing the corundum furnace tube to be broken by the fallen graphite crucible. Utility Model Content

[0005] In order to facilitate the placement and removal of a graphite crucible in a corundum furnace tube and reduce the possibility that the corundum furnace tube is broken by the graphite crucible, the present application provides a material holding tool for measuring the viscosity of blast furnace slag.

[0006] The present application provides a material holding tool for measuring the viscosity of blast furnace slag, which adopts the following technical solution:

[0007] A material holding tool for measuring the viscosity of blast furnace slag, comprising a base, a crucible is arranged on the base, a sample cavity is provided on the top of the crucible, a clamping seat is arranged in the sample cavity, a side wall of the clamping seat is fixedly connected to the crucible, a through hole is provided on the clamping seat, a plurality of clamping arms are movably arranged in the through hole, an elastic frame is jointly arranged on the top of the clamping arms, the elastic frame is used to deform, a clamping hook is fixedly arranged on the bottom of the clamping arm, a clamping ring groove is provided at the bottom of the clamping seat, and the clamping ring groove is for inserting the clamping hook.

[0008] By adopting the above technical scheme, when taking and placing the crucible, the staff holds the elastic frame and pinches the elastic frame to apply a lateral force to it, so that the elastic frame is deformed and drives the clamping arms to approach each other, and then the staff moves the elastic frame in the height direction, so that the clamping hooks on the clamping arms enter the sample cavity from the through hole. When the clamping hooks are located below the clamping ring groove, the staff cancels the lateral force applied to the elastic frame, and the elastic frame drives the clamping arms away from each other, and then the staff moves the elastic frame in the height direction, so that the clamping hooks on the clamping arms are inserted into the clamping ring groove, and then the staff drives the crucible to move by moving the elastic frame, and the clamping hooks are clamped on the clamping seat under the influence of the crucible's own weight, so that the crucible is not easy to fall, and the corundum furnace tube is reduced. The situation of being broken by the graphite crucible reduces, and the effect of facilitating the placement of the graphite crucible inside the corundum furnace tube is achieved.

[0009] Preferably, the inner wall of the through hole abuts against the clamping arm.

[0010] By adopting the above technical solution, when the clamping hook is inserted into the clamping ring groove, the clamping arm abuts against the inner wall of the through hole, so that the clamping arm is not easy to drive the clamping hooks away from each other, so that the force on the clamping arm is uniform.

[0011] Preferably, abutment groove is provided on one side of the snap ring groove close to the through hole, the inner wall of the abutment groove is inclined, the upper diameter of the abutment groove is smaller than the lower diameter of the abutment groove, and the inner wall of the abutment groove is used to abut against the snap hook.

[0012] By adopting the above technical solution, when the snap hook is inserted into the snap ring groove, the snap hook and the inner wall of the abutment groove abut against each other, making it difficult for the snap hooks to approach each other, and then making it difficult for the snap arms to approach each other, thereby reducing the chance of the snap hook slipping out of the snap ring groove.

[0013] Preferably, the sample cavity is cylindrical, the inner diameter of the sample cavity is 50 mm, and the height of the sample cavity is 110 mm.

[0014] By adopting the above technical solution, the charge is added to 80mm of the sample cavity, and when the viscosity of the charge is tested, the charge in the sample cavity is not easy to overflow.

[0015] Preferably, the height of the clamping seat is 10 mm, and the distance between the bottom of the clamping seat and the bottom wall of the sample chamber is 100 mm.

[0016] By adopting the above technical solution, when the charge is added into the sample cavity, the bottom of the clamping seat is about 20 mm away from the charge surface, so the clamping hook is not easy to contact with the charge during the movement of the clamping hook in the sample cavity.

[0017] Preferably, a receiving groove is provided on the top of the base, a receiving seat is arranged in the receiving groove, and the top of the receiving seat is fixedly connected to the bottom of the crucible.

[0018] By adopting the above technical solution, when the crucible is placed on the base, the receiving seat is placed in the receiving groove, and then the receiving seat is confined in the receiving groove, so that the crucible is not easy to tip over.

[0019] Preferably, the cross-section of the receiving seat is an isosceles trapezoid, the lower diameter of the receiving seat is smaller than the upper diameter of the receiving seat, the receiving groove includes an upper receiving groove and a lower receiving groove, the upper receiving groove is located above the lower receiving groove, the upper receiving groove and the lower receiving groove are connected to each other, the cross-sections of the upper receiving groove and the lower receiving groove are both isosceles trapezoidal, the upper diameter of the upper receiving groove is equal to the upper diameter of the receiving seat, the upper diameter of the upper receiving groove is greater than the lower diameter of the upper receiving groove, the lower diameter of the upper receiving groove is equal to the upper diameter of the receiving lower groove, the upper diameter of the lower receiving groove is greater than the lower diameter of the lower receiving groove, and the lower diameter of the lower receiving groove is greater than the lower diameter of the receiving seat.

[0020] By adopting the above technical solution, since the upper diameter of the receiving upper groove is larger than the lower diameter of the receiving seat, it is convenient to insert the bottom of the receiving seat into the receiving groove during the process of placing the crucible on the base.

[0021] Preferably, a clearance groove is provided at the bottom of the base, the clearance groove is communicated with the receiving lower groove, and the central thermocouple is inserted in the clearance groove.

[0022] By adopting the above technical solution, the central thermocouple is inserted in the give way groove, which is convenient for the central thermocouple to detect the central temperature, and a silicon-molybdenum rod is used for heating.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a material container for measuring the viscosity of blast furnace slag. Figure 1 and Figure 2 , which includes a base 1, which is cylindrical, 260mm high, and 70mm in cross-sectional diameter. A crucible 2 is placed on the base 1, which is cylindrical, 125mm high, and 70mm in cross-sectional diameter. A sample chamber 21 is provided at the top of the crucible 2, and a clamping seat 3 is installed in the sample chamber 21. The side wall of the clamping seat 3 is fixedly connected to the inner wall of the crucible 2, and the diameter of the clamping seat 3 is 50mm. A through hole 31 is provided on the clamping seat 3, and the diameter of the through hole 31 is 45mm. A plurality of clamping arms 41 are movably arranged in the through hole 31. An elastic frame 4 is installed on the top of the clamping arm 41, and the elastic frame 4 is made of iron wire, and the elastic frame 4 is used for deformation. A clamping hook 42 is installed at the bottom of the clamping arm 41, and the clamping hook 42 and the clamping arm 41 together form a V shape. A clamping ring groove 32 is provided at the bottom of the clamping seat 3, and the clamping ring groove 32 is provided for the clamping hook 42 to be inserted. When taking or placing the crucible 2, the staff holds the elastic frame 4 and pinches the elastic frame 4 to exert a lateral force on it, so that the elastic frame 4 is deformed and drives the clamping arms 41 to approach each other, and the clamping arms 41 approach each other and drive the clamping hooks 42 to approach each other. Then the staff moves the elastic frame 4 in the height direction so that the clamping hooks 42 on the clamping arms 41 enter the sample chamber 21 from the through hole 31. When the clamping hooks 42 are located below the clamping ring groove 32, the staff cancels the lateral force exerted on the elastic frame 4, and the elastic frame 4 drives the clamping arms 41 to move away from each other, and then the staff moves the elastic frame 4 in the height direction so that the clamping hooks 42 on the clamping arms 41 are inserted into the clamping ring groove 32. Then, a clamping relationship is formed among the clamping arm 41, the clamping hook 42 and the clamping seat 3. When the staff moves the elastic frame 4, the elastic frame 4 drives the crucible 2 to move, and the clamping hook 42 is clamped on the clamping seat 3 under the influence of the deadweight of the crucible 2, so that the crucible 2 is not easy to fall, and the corundum furnace tube is reduced from being broken by the graphite crucible 2, so as to achieve the effect of facilitating the taking and placing of the graphite crucible 2 inside the corundum furnace tube.

[0033] In order to improve the stability of the connection between the clamping hook 42 and the clamping seat 3, refer to Figure 1 and Figure 2The clamping ring groove 32 is provided with an abutting groove 33 on one side close to the through hole 31. The inner wall of the abutting groove 33 is inclined, and the upper diameter of the abutting groove 33 is smaller than the lower diameter of the abutting groove 33. When the clamping hook 42 is inserted into the clamping ring groove 32, the inner wall of the abutting groove 33 abuts against the clamping hook 42, and the inner wall of the through hole 31 abuts against the clamping arm 41. The clamping arm 41 is not easy to drive the clamping hook 42 away from each other, and the clamping hook 42 is not easy to get close to each other. On the one hand, the force on the clamping arm 41 is uniform, and on the other hand, the clamping hook 42 is not easy to slip out of the clamping ring groove 32.

[0034] In order to prevent the hook 42 from contacting the charge, Figure 1 and Figure 2 The sample cavity 21 is cylindrical, the inner diameter of the sample cavity 21 is 50mm, and the height of the sample cavity 21 is 110mm. The height of the clamping seat 3 is 10mm, and the distance between the bottom of the clamping seat 3 and the bottom wall of the sample cavity 21 is 100mm. When the charge is added to the sample cavity 2180mm, the charge in the sample cavity 21 is not easy to overflow when the viscosity is tested. After the charge is added to the sample cavity 21, the bottom of the clamping seat 3 is about 20mm away from the charge surface. Therefore, when the clamping hook 42 moves in the sample cavity 21, it is not easy for the clamping hook 42 to contact the charge.

[0035] In order to prevent the crucible 2 from tipping over, refer to Figure 1 and Figure 3 , a receiving groove 5 is provided at the top of the base 1, and the receiving groove 5 includes an upper receiving groove 51 and a lower receiving groove 52, and the upper receiving groove 51 is located above the lower receiving groove 52, and the upper receiving groove 51 and the lower receiving groove 52 are connected to each other. The cross section of the upper receiving groove 51 is an isosceles trapezoid, the height of the upper receiving groove 51 is 2.5mm, the upper diameter of the upper receiving groove 51 is 70mm, and the lower diameter of the upper receiving groove 51 is 55mm. The cross section of the lower receiving groove 52 is an isosceles trapezoid, the height of the lower receiving groove 52 is 7.5mm, the upper diameter of the lower receiving groove 52 is 55mm, and the lower diameter of the lower receiving groove 52 is 50mm. The top of the receiving seat 6 is integrally formed at the bottom of the crucible 2, and the upper receiving groove 51 and the lower receiving groove 52 are used to place the receiving seat 6. The cross section of the receiving seat 6 is an isosceles trapezoid, the height of the receiving seat 6 is 5mm, the lower diameter of the receiving seat 6 is 45mm, and the upper diameter of the receiving seat 6 is 70mm. When the crucible 2 is placed on the base 1, since the lower diameter of the receiving seat 6 is smaller than the upper diameter of the receiving upper groove 51, it is convenient for the bottom of the receiving seat 6 to be inserted into the receiving groove 5. After the receiving seat 6 is placed in the receiving groove 5, the receiving seat 6 is restricted in the receiving groove 5, so that the crucible 2 is not easy to tip over.

[0036] In order to facilitate the central thermocouple to detect the temperature of crucible 2, refer to Figure 1 and Figure 3The bottom of the base 1 is provided with a clearance groove 11, which is cylindrical and has a diameter of 50 mm. The clearance groove 11 is connected to the receiving lower groove 52, and the clearance groove 11 is provided for the central thermocouple to be inserted. The central thermocouple is inserted in the clearance groove 11, so that the central thermocouple can detect the crucible 2.

[0037] The implementation principle of a material holding tool for measuring the viscosity of blast furnace slag in the embodiment of the present application is as follows: when taking and placing the crucible 2, the staff holds the elastic frame 4, and the staff pinches the elastic frame 4 to apply a lateral force to it, so that the elastic frame 4 is deformed to drive the clamping arms 41 to approach each other, and the clamping arms 41 approach each other to drive the clamping hooks 42 to approach each other. Then the staff moves the elastic frame 4 in the height direction, so that the clamping hooks 42 on the clamping arms 41 enter the sample chamber 21 from the through hole 31. When the clamping hooks 42 are located below the clamping ring groove 32, the staff cancels the lateral force applied to the elastic frame 4, and the elastic frame 4 drives the clamping arms 41 away from each other, and then the staff moves the elastic frame 4 in the height direction, so that the clamping hooks 42 on the clamping arms 41 are inserted into the clamping ring groove 32, and the inner wall of the abutting groove 33 abuts against the clamping hooks 42, and the inner wall of the through hole 31 abuts against the clamping arms 41, and then a clamping relationship is formed between the clamping arms 41, the clamping hooks 42 and the clamping seat 3. When the staff moves the elastic frame 4, the elastic frame 4 drives the crucible 2 to move, and the clamping hook 42 is clamped on the clamping seat 3 under the influence of the dead weight of the crucible 2, so that the crucible 2 is not easy to fall, and the corundum furnace tube is reduced from being broken by the graphite crucible 2, so as to achieve the effect of facilitating the removal and placement of the graphite crucible 2 inside the corundum furnace tube.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
