TECHNICAL FIELD

[0001] The present application relates to molten steel sampling technical field, especially to a kind of smelting molten steel sampling spoon. BACKGROUND

[0002] With the rapid development of modern society, the use of parts in casting industry is more and more demanding, and the product requirements are increasing, the complexity increases, the material types are more and more, and the performance requirements are more and more strict. Many products applied in aviation, aerospace, ship, automobile and other fields are special material products, and the composition is more difficult to meet the requirements than ordinary material products during smelting. Therefore, multiple composition adjustments are required during smelting to meet the requirements for pouring mold.

[0003] In order to know whether the composition is qualified, a part of molten steel is taken out, cooled and sent to spectrometer for composition analysis. The temperature of molten steel may be above 1700 degrees, and if repeatedly close to the temperature of smelting furnace or ladle, the temperature will be very high, especially in summer. The sampling spoon must be inserted into the molten steel, because the steel slag covering the surface of the molten steel will affect the analysis result. The cold spoon inserted into the molten steel may splash some steel flowers, which will burn a hole in the clothes if falling on the clothes, so the workers are reluctant to approach the smelting furnace or ladle. SUMMARY

[0004] The purpose of the present application is to solve the problem of high temperature near smelting furnace or ladle during molten steel sampling process in the prior art, and to provide a smelting molten steel sampling spoon.

[0005] In order to achieve the above purpose, the present application adopts the following technical scheme: a smelting molten steel sampling spoon, comprising a spoon body, an installation block is fixed at the upper end of the spoon body, a reinforcing rod is fixed at the upper end of the installation block, a connecting head is fixed at the end of the reinforcing rod, a heat conducting rod is fixed at the side wall end of the connecting head, a clamping sleeve is fixed at the end of the heat conducting rod, an insertion block is connected to the inner wall of the clamping sleeve through a clamping mechanism, an inner sleeve rod is fixed at the end of the insertion block, and a telescopic handle with adjustable length is connected to the side wall of the inner sleeve rod.

[0006] In the smelting molten steel sampling spoon described above, two connecting blocks are rotatably connected to the side wall of the reinforcing rod, and a bottom supporting spoon is fixed at the bottom of the two connecting blocks.

[0007] In the smelting molten steel sampling spoon described above, the bottom of the spoon body is slidably connected to the inner wall of the bottom supporting spoon, the spoon body and the bottom supporting spoon are both semispherical structures, and the center of gravity of the bottom supporting spoon is located at the center of the arc surface bottom.

[0008] In the smelting molten steel sampling spoon, the side wall of the telescopic handle is provided with a sealed rotary hole, the inner wall of the sealed rotary hole is fixedly provided with a connecting screw rod, the connecting screw rod is in threaded connection with the inner wall of an internal screw sleeve rod, and the sealed rotary hole is in sealing movable connection with the outer wall of the internal screw sleeve rod.

[0009] In the smelting molten steel sampling spoon, the outer wall of the telescopic handle is fixedly provided with an electric box, and the internal screw sleeve rod is filled with electrorheological fluid.

[0010] In the smelting molten steel sampling spoon, the end of the telescopic handle is provided with a heat dissipation groove, the end of the telescopic handle is fixedly provided with a heat dissipation bag in communication with the heat dissipation groove, the outer wall of the telescopic handle is embedded with a plurality of refrigeration fins, the inner wall of the heat dissipation groove is inserted with a plurality of heat conduction fins in contact with the side wall of the refrigeration fin, and the heat dissipation groove and the heat dissipation bag are filled with cooling liquid.

[0011] In the smelting molten steel sampling spoon, the clamping mechanism comprises a receiving groove formed in the plug, two sealing plates are movably connected to the inner wall of the receiving groove, the two sealing plates are connected by a connecting spring, the side walls of the two sealing plates are fixedly provided with clamping blocks, the side wall of the clamping sleeve is provided with two clamping grooves, the two clamping blocks are movably connected to the two clamping grooves respectively, the two sides of the clamping block inside the clamping groove are inclined surfaces, and the receiving groove is filled with evaporative liquid.

[0012] Compared with the prior art, the advantages of the present application are that:

[0013] 1. The overall length of the telescopic handle and the internal screw sleeve rod can be adjusted at will, thereby facilitating overall sampling, improving the safety of sampling, allowing free operation, being convenient and fast, and greatly improving work efficiency.

[0014] 2. A section connected with the spoon body is placed in the boiler for heating treatment, so that the temperature of the spoon body is raised, thereby avoiding splashing of the low-temperature spoon body when encountering high-temperature molten steel in subsequent sampling, and improving the safety of the sampling process.

[0015] 3. The preheating does not affect the actual holding part, so that the holding part remains in a low-temperature state in the subsequent sampling process, facilitating worker operation.

[0016] 4. The clamping sleeve and the plug are effectively clamped in a high-temperature environment, ensuring the stability of the connection during sampling, and cannot be directly pulled apart when the temperature of the tool has not recovered, thereby avoiding unintentional burns caused by the high-temperature spoon body section and improving the safety of subsequent placement.

[0017] 5. When the cooling chip is powered on, the outer side absorbs heat and the inner side heats up, keeping the part held by the person in a cool state. This ensures that even when the person is in contact with a high-temperature environment, the part held by the person is still in a relatively low-temperature state, thus ensuring the stability of the grip and preventing injury from drops during the transfer process.

[0018] 6. The inner wall space of the bottom scoop is larger than that of the scoop body, so the molten steel cannot fill the bottom scoop. Combined with the fact that the upper part of the bottom scoop is sealed by the scoop body, the stability of the molten steel transfer process can be greatly improved, molten steel spillage can be avoided, and the overall sampling safety can be improved.

[0027] Example

[0028] Reference Figures 1-6The utility model provides a smelt molten iron sampling spoon, including the spoon body 1, the upper end of spoon body 1 is fixed with the mounting block 2, the upper end of mounting block 2 is fixed with the reinforcing rod 3, the end of reinforcing rod 3 is fixed with the connector 4, the side wall end of connector 4 is fixed with the heat conduction rod 5, the end of heat conduction rod 5 is fixed with the sleeve 6, the inner wall of sleeve 6 is connected with the plug 7 through the clamping mechanism, the end of plug 7 is fixed with the inner screw sleeve rod 8, the side wall of inner screw sleeve rod 8 is connected with the telescopic handle 9 of adjustable length.

[0029] The side wall of reinforcing rod 3 is rotatably connected with two connecting blocks 15, and the bottom of the two connecting blocks 15 is fixed with a bottom supporting spoon 14; the bottom of spoon body 1 is slidably connected with the inner wall of bottom supporting spoon 14, and the bottom supporting spoon 14 and the spoon body 1 are both hemispherical structures, the center of gravity of the bottom supporting spoon 14 is located at the center position of the arc surface bottom, the opening of the bottom supporting spoon 14 faces downward due to the low center of gravity and cannot be easily changed, thereby ensuring effective load bearing, and the spoon body 1 can be rotated upward to be closed.

[0030] The side wall of telescopic handle 9 is provided with a sealed rotary hole 10, the inner wall of sealed rotary hole 10 is fixed with a connecting screw 11, the connecting screw 11 is threadedly connected with the inner wall of inner screw sleeve rod 8, and sealed rotary hole 10 is sealingly and movably connected with the outer wall of inner screw sleeve rod 8.

[0031] The outer wall of telescopic handle 9 is fixed with an electric power box 12, the inside of inner screw sleeve rod 8 is filled with an electro-rheological fluid, and the electro-rheological fluid solidifies and expands after being electrified, thereby blocking the thread gap and locking the connection between telescopic handle 9 and inner screw sleeve rod 8.

[0032] The end of telescopic handle 9 is provided with a heat dissipation groove 17, the end of telescopic handle 9 is fixed with a heat dissipation bag 16 connected with heat dissipation groove 17, the outer wall of telescopic handle 9 is embedded with a plurality of refrigeration fins 13, the inner wall of heat dissipation groove 17 is inserted with a plurality of heat conduction fins 18 in contact with the side wall of refrigeration fin 13, the inside of heat dissipation groove 17 and heat dissipation bag 16 is filled with a cooling liquid, and the refrigeration fin 13 is a semiconductor refrigeration fin, which generates heat on one side and cools on the other side after being electrified, the cooling side is the outer side, so that the part held by the personnel is in a low-temperature state.

[0033] The clamping mechanism comprises a receiving groove 19 formed in the inside of the plug 7, the inner wall of the receiving groove 19 is sealed and slidably connected with two sealing plates 20, the two sealing plates 20 are connected through a connecting spring 22, the side walls of the two sealing plates 20 are fixedly connected with clamping blocks 21, the side wall of the clamping sleeve 6 is penetrated and formed with two clamping grooves 23, the two clamping blocks 21 are slidably connected with the two clamping grooves 23 respectively, the two sides of the clamping block 21 located in the inside of the clamping groove 23 are inclined surfaces, the receiving groove 19 is filled with evaporative liquid, the evaporative liquid is dichloromethane solution, the evaporative liquid is located at the middle position between the two sealing plates 20 and is used for separating the two sealing plates 20 by heating, the cross section of the clamping block 21 is hexagonal, the side edges are inclined edges and numerical variable components, so that the side of the clamping block 21 is composed of inclined surfaces and vertical surfaces, thus, when the inclined surfaces of the clamping block 21 are located in the clamping groove 23, the clamping block 21 cannot bear strong pulling, and once the vertical surfaces enter the clamping groove 23, strong pulling cannot cause vertical separation, so the clamping block 21 cannot be driven to move, thereby the stability of clamping is ensured.

[0034] In actual use, the installation length of the telescopic handle 9 is adjusted according to the need, so that the sampling of different sizes of smelting furnaces or ladles is satisfied, when adjusting, the telescopic handle 9 is rotated to drive the connecting screw rod 11 to rotate, so that the connecting screw rod 11 and the inner screw sleeve rod 8 are relatively rotated, and then the connecting screw rod 11 is separated or deeply inserted into the inner screw sleeve rod 8, so that the overall length of the telescopic handle 9 and the inner screw sleeve rod 8 is adjusted, thereby the overall sampling is facilitated, and the safety of sampling is improved.

[0035] Before sampling, the inner screw sleeve rod 8 and the heat conduction rod 5 are pulled in the reverse direction, so that the clamping sleeve 6 and the plug 7 can overcome the elastic force of the connecting spring 22, the clamping block 21 is squeezed into the receiving groove 19, and finally the clamping sleeve 6 and the plug 7 are separated, so that the whole is divided into two sections, one section connected with the spoon body 1 is put into the boiler for heating treatment, so that the temperature of the spoon body 1 is increased, thereby in the subsequent sampling, the low-temperature spoon body 1 is prevented from splashing when meeting the high-temperature molten steel, so that the safety of the sampling process is improved, and the preheating of this section does not affect the part actually held, so that the holding part still maintains a low-temperature state in the subsequent sampling process, which is convenient for workers to operate.

[0036] After the spoon body 1 is preheated, the plug 7 is inserted into the clamping sleeve 6, the clamping block 21 reenters the clamping groove 23, and at this time, the clamping sleeve 6 is in a high-temperature state, so the evaporative liquid in the receiving groove 19 is heated, so that the evaporative liquid is vaporized and expanded, so that the clamping block 21 is further moved into the clamping groove 23, so that the vertical parts on both sides of the clamping block 21 enter the clamping groove 23, so that the external transverse force cannot push the clamping block 21 back, so that the clamping sleeve 6 and the plug 7 are effectively clamped, the stability of the connection is ensured in the sampling process, and when the temperature of the tool is not restored, it cannot be directly pulled apart, so that the high-temperature spoon body 1 section cannot cause unintentional burns, and the safety of the use and placement is improved.

[0037] Because the heat conduction rod 5 has good heat conduction capacity, after the molten steel sampling, the heat conduction of the molten steel will make the evaporated liquid further gasify, so that the clamping is more stable;

[0038] When formal sampling, the power box 12 switch starts to supply power outward, so that the current of the liquid in the inner sleeve rod 8 is electrified and solidified, so that the thread gap between the inner sleeve rod 8 and the connecting screw rod 11 is filled and blocked, so that the inner sleeve rod 8 and the connecting screw rod 11 cannot rotate and separate, so as to ensure the stability of the telescopic length and the connection, avoid the uneven stress of the spoon body 1 when holding the telescopic handle 9, causing the inner sleeve rod 8 to rotate, causing the instability of the sampling process, avoiding the instability risk;

[0039] At the same time, the power supply in the power box 12 supplies power to the refrigeration sheet 13, so that the refrigeration sheet 13 is electrified, the outside absorbs heat, and the inside generates heat, so that the part held by the personnel is in a cooling state, so that the personnel can ensure the stability of holding when sampling, even if contacting high temperature environment, the part held by the personnel is still in a relatively low temperature state, so as to avoid the damage of personnel caused by falling during the transfer process;

[0040] And the heat generated by the heat conduction sheet 18 is quickly conducted out, reduced by the cooling liquid, and quickly diffused to the outside through the heat dissipation bag 16, so as to ensure the effective and continuous refrigeration capacity;

[0041] When the spoon body 1 contacts the molten steel for sampling, the spoon body 1 moves down into the molten steel, the molten steel enters the inside of the spoon body 1, then the spoon body 1 moves up, the molten steel is lifted, then the telescopic handle 9 is rotated, the reinforcing rod 3 is rotated, so as to drive the spoon body 1 to rotate, because the bottom spoon 14 is heavy and the center of gravity is low, the rotation of the reinforcing rod 3 will not drive the bottom spoon 14 to rotate synchronously, so that after the spoon body 1 rotates, the molten steel in the spoon body 1 enters the bottom spoon 14, and the spoon body 1 gradually rotates to the upper region, so as to cover and close the upper end of the bottom spoon 14, so that the molten steel in the bottom spoon 14 is covered and treated, and the inner wall space of the bottom spoon 14 is larger than that of the spoon body 1, so that the molten steel cannot fill the bottom spoon 14, combined with the upper closure of the bottom spoon 14, the stability of the molten steel transfer process can be greatly improved, and the safety of the whole sampling can be improved.

[0042] The above only describes the preferred embodiments of the present application, and does not limit the present application, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
