Description

Technical Field

[0001] The present application relates to the technical field of iron and steel metallurgy, and in particular to efficient operation equipment capable of automatically breaking, picking and delivering molten steel samples during the iron and steel smelting process. Background Art

[0002] The main purpose of testing molten steel samples in steel smelting is to conduct quality control and analysis. Since the temperature, composition and structure of molten steel may change during the smelting process, sample testing can help monitor these changes, adjust smelting parameters in time, and ensure the quality of the final product.

[0003] The traditional steel and metallurgical industry uses manual operations to break, pick and deliver molten steel samples. Operators wear protective equipment, such as heat-resistant gloves, protective glasses, etc., and use special sampling tools to take the molten steel from the sampling position. They use sample breaking tools and sample picking tools to manually break and pick up the samples. After picking up the samples, they are quickly placed in pre-prepared sample containers, and then the sealed samples are sent to a special inspection room.

[0004] The state of the molten steel sample is a red-hot ultra-high temperature solid state (about 1000℃). There are great safety hazards in the manual operation process, which has an impact on the safety and health of personnel. In addition, the time for manual sample breaking, picking and sending is uncontrollable, which easily leads to the delay of sample inspection and analysis results, and has a great impact on the existing casting composition control. In addition, in the existing manual sample breaking and picking process, the sampling is successful only by visually observing whether the surface of the steel sample is intact, whether the steel sample is full and whether the steel sample is qualified. It is impossible to accurately judge manually. Moreover, in the existing manual sample breaking, picking and sending process, the steel sample needs to be labeled manually, and there is a risk of confusion between different steel samples. In addition, the traditional method of sample breaking, picking and sending is inefficient and has high labor costs. Therefore, it is urgent to propose a new technical solution to solve the problems existing in the existing technology. Summary of the invention

[0010] 2. When the sample breaking device in the present application is used for automatic sample breaking, after the sampler completes sampling through the mud ball at its front end, the mud ball of the sampler hits the front end of the molten steel sample and is placed into the sample breaking bin. Then, the mud ball of the sampler is hammered at high frequency through two hammer breaking mechanisms to break the mud ball of the sampler, so that the upper shell and the lower shell of the molten steel sample are slid and separated from the molten steel sample, and the mud ball is broken and separated from the paper tube of the sampler.

Therefore, the present application automatically sorts the molten steel sample after sample breaking through the vibration centrifugal sorting component, and then determines the position and status of the molten steel sample in the vibration centrifugal separation chamber through the sampling vision CCD component, and then picks up the sample through the picking component, thereby automatically completing the molten steel sample picking operation with high sampling efficiency.

[0043] In order to solve the problems existing in the prior art, the present application provides a sample breaking, sample picking and sample delivery equipment for molten steel samples. Through the equipment, an unmanned operation process route of automatic sample breaking, automatic sample picking and automatic sample delivery can be completed, which effectively solves the existing manual operations of sample breaking, sample picking and sample delivery of molten steel samples after sampling is completed, and isolates the safety risk of ultra-high temperature burns of about 1000°C of molten steel samples during manual sample breaking, sample inspection and sample delivery; shortens the operation time of the intermediate links from sampling to inspection of samples; and improves the process control capability of each smelting station and the quality control capability during the casting process.

[0044] The present application provides a sample breaking, sampling and sample delivery device for molten steel samples, such as Figures 1 to 3 The equipment mainly includes a sample breaking device, a sample picking device and a sample delivering device. The three devices constituting the equipment are described one by one below.

[0045] 1. Sample breaking device

[0046] See also Figure 4 , 5The sample breaking device 100 in the present application mainly includes a molten steel sample breaking part 120 and a hammer breaking mechanism. Among them: the molten steel sample breaking part 120 mainly includes a sample breaking chamber 121 for accommodating the sampler mud ball, the bottom of the sample breaking chamber 121 forms a sample outlet, and an opening and closing mechanism for opening or closing the sample outlet is installed at the sample outlet. When the hammer breaking mechanism hammers the molten steel sample and the mud ball head captured by the sampler mud ball, the sample outlet can be opened to discharge the material. The hammer breaking mechanism includes a first hammer breaking mechanism 110 and a second hammer breaking mechanism 140. The two hammer breaking mechanisms are correspondingly installed on both sides of the sample breaking chamber 121. The two hammer breaking mechanisms are used to knock and break the sampler mud ball, so that the upper shell and the lower shell of the molten steel sample are slid and separated from the molten steel sample, and the mud ball is broken and separated from the sampler paper tube. After taking away the sampler paper tube, the sample and the broken mud ball particles can be obtained in the sample breaking chamber 121.

[0047] Compared with traditional manual sample breaking operations, the sample breaking device 100 in the present application realizes automated sample breaking through a hammer breaking mechanism and a sample outlet that can be opened or closed. It has standardized operating procedures and efficient operating processes, reduces manual participation, and achieves reduction in staff, cost reduction, and efficiency improvement.

[0048] In one embodiment, the sample breaking bin 121 is a shell structure, preferably a rectangular or cube-shaped shell structure, which is easy to process and manufacture. A cavity is formed in the shell structure to accommodate the sampler mud ball. The structural dimensions of the cavity are adapted to the structural dimensions of the front end of the sampler mud ball racket molten steel sample. An inlet is formed above the cavity, and the sampler mud ball is inserted into the cavity from the inlet. During specific application and installation, a loading robot can be equipped to automatically insert the sampler mud ball into the molten steel for sampling and insert the sampler mud ball into the sample breaking bin 121 after sampling, thereby realizing unmanned production. At the same time, a sealing door or other structure can also be provided at the inlet to prevent leakage from the molten steel.

[0049] In one embodiment, the first hammer mechanism 110 includes a first sample-breaking hammer 114 and a first driver driving the first sample-breaking hammer 114, and the second hammer mechanism 140 includes a second sample-breaking hammer 144 and a second driver driving the second sample-breaking hammer 144. The first sample-breaking hammer 114 and the second sample-breaking hammer 144 can be driven to reciprocate and hammer the sampler mud ball in the cavity. In this embodiment, the first driver and the second driver can be any linear actuator, such as an electric linear actuator, which uses an electric motor as a driving source and converts the rotary motion generated by the rotating motor into linear motion. Common ones include screw drive, chain drive, etc.; another example is a hydraulic linear actuator, which uses the liquid in the hydraulic system as a power source, controls the flow of the liquid by adjusting the hydraulic valve, and pushes the piston to achieve linear motion. In this embodiment, the hammer is automatically driven to reciprocate by the linear actuator, and the driving force is controllable. The movement speed, position and acceleration of the hammer can be precisely controlled to achieve highly precise movement. In addition, linear actuators are simple in design and have fewer parts, so they usually have higher reliability and long life. Hydraulic and pneumatic actuators, in particular, are more durable in harsh environments and can operate at higher speeds and greater forces, thus reducing the hammering time.

[0050] In another embodiment, the first hammer mechanism 110 includes a first sample-breaking hammer 114 and a first driver driving the first sample-breaking hammer 114, and the second hammer mechanism 140 includes a second sample-breaking hammer 144 and a second driver driving the second sample-breaking hammer 144, and the first sample-breaking hammer 114 and the second sample-breaking hammer 144 can be driven to reciprocately hammer the sampler mud ball in the cavity. Wherein: the first driver includes a first hammer propulsion cylinder 111 and a first air hammer assembly 113 connected to the power output end of the first hammer propulsion cylinder 111, and the first air hammer assembly 113 is connected to the first sample-breaking hammer 114; the first hammer mechanism 110 also includes a first linear moving assembly 112 for guiding the first sample-breaking hammer 114; the first linear moving assembly 112 includes a first guide rail and a first slider adapted to be slidably mounted on the first guide rail, the first slider is connected to the first air hammer assembly 113, and the length direction of the first guide rail is the same as the hammering direction of the first sample-breaking hammer 114. Similarly, the second driver includes a second hammer propulsion cylinder 141 and a second air hammer assembly 143 connected to the power output end of the second hammer propulsion cylinder 141, and the second air hammer assembly 143 is connected to the second sample breaking hammer head 144. The second hammer breaking mechanism 140 also includes a second linear motion assembly 142 for guiding the second sample breaking hammer head 144. The second linear motion assembly 142 includes a second guide rail and a second slider adapted to be slidably mounted on the second guide rail, the second slider is connected to the second air hammer assembly 143, and the length direction of the second guide rail is the same as the hammering direction of the second sample breaking hammer head 144.

[0051] The first air hammer assembly 113 and the second air hammer assembly 143 can use compressed air or gas as a power source, and control the movement of the piston through a pneumatic valve, thereby achieving linear movement of the hammer head.

[0052] In one embodiment, the above-mentioned sample breaking chamber 121 is a shell structure surrounded by a first side wall 1211, a second side wall 1212, a third side wall 1213, a fourth side wall 1214 and a bottom wall 1215, wherein: the first side wall 1211 and the second side wall 1212 are adjacent to each other and form a right angle, the fourth side wall 1214 is opposite to the lower half of the first side wall 1211, and an opening allowing the first sample breaking hammer 114 to enter and exit is formed above the fourth side wall 1214; the third side wall 1213 is opposite to the upper half of the second side wall 1212, and an opening allowing the second sample breaking hammer 144 to enter and exit is formed below the third side wall 1213 and above the bottom wall 1215, that is, the hammering point of the first sample breaking hammer 114 in the present application is higher than the hammering point of the second sample breaking hammer 144.

[0053] The bottom wall 1215 is installed at the sample outlet. In order to open or close the sample outlet, the present application opens a horizontal sliding socket on the first side wall 1211, and sets a slide on the inner surface of the second side wall 1212. The bottom wall 1215 can be inserted into the sample breaking chamber 121 from the horizontal sliding socket, and one side of the bottom wall 1215 is slidably connected to the slide. A corresponding card slot is opened on the inner surface of the fourth side wall 1214. One end of the bottom wall 1215 is adapted to be plugged into the horizontal sliding socket, and the other end is adapted to be plugged into the card slot. In this way, the horizontal sliding and structural installation of the bottom wall 1215 are achieved.

[0054] The opening and closing mechanism for opening or closing the sample outlet in the present application includes a driving cylinder 122 installed on the outer surface of the first side wall 1211, and the power output end of the driving cylinder 122 is connected to the end of the bottom wall 1215 extending out of the horizontal sliding socket. The bottom wall 1215 can slide back and forth relative to the horizontal sliding socket under the drive of the driving cylinder 122 to open or close the sample outlet. Of course, the opening and closing mechanism can also use a motor and a ball screw structure or other linear actuators, as long as the horizontal drive of the bottom plate can be achieved.

[0055] In one embodiment, a sample falling guide cylinder 130 can be installed below the sample outlet of the sample breaking bin 121, and a vibrating centrifugal sorting component 210 can be installed below the sample falling guide cylinder 130. In this way, the sample and crushed mud ball particles in the sample breaking bin 121 can automatically fall into the vibrating centrifugal sorting component 210 below through the opening and closing mechanism to realize automatic sorting and processing, which is beneficial to the realization of full-process automation of molten steel sampling and testing.

[0056] Therefore, the sample breaking device 100 in the present application uses a cylinder to drive a high-frequency air hammer to strike the steel sample mud head, effectively breaking the sample while ensuring the integrity of the sample, and uses an upper hammer and a lower hammer to break the mud head part of the sample and detach the sample shell, thereby realizing automatic sample breaking.

[0057] 2. Sample Picking Device

[0058] See also Figure 6 , 7 The sampling device 200 in the present application mainly includes a vibrating centrifugal sorting component 210 and a visually guided sampling component 220. The vibrating centrifugal sorting component 210 mainly includes a separation bin bottom plate 212, a vibrating centrifugal separation bin 211 disposed above the separation bin bottom plate 212, a vibration generator 213 and a plurality of booster spring groups 214 disposed below the separation bin bottom plate 212, and a centrifugal drive assembly 215 disposed below the vibrating centrifugal separation bin 211. A vibrating centrifugal disc 219 is disposed in the vibrating centrifugal separation bin 211, and the vibrating centrifugal disc 219 is connected to the power output end of the centrifugal drive assembly 215. The side wall of the vibrating centrifugal separation bin 211 is provided with an upper shell and a lower shell that allow the crushed mud particles and molten steel samples to be discharged and prevent the molten steel samples from being discharged. The discharge port 218 is provided.

[0059] The visually guided sampling component 220 includes a sampling visual CCD component 223 and a picking component 226. The sampling visual CCD component 223 is used to collect image information of the molten steel sample in the vibrating centrifugal separation chamber 211. The image information includes the position and state information of the molten steel sample. The visually guided sampling component 220 adjusts the position state of the molten steel sample in the vibrating centrifugal separation chamber 211 through the picking component 226 and picks up the sample.

[0060] The separation bin bottom plate 212 in the vibrating centrifugal sorting component 210 not only serves to install the vibrating centrifugal separation bin 211 and the cylindrical side wall of the vibrating centrifugal separation bin 211 to form a cavity, but also serves to install the vibration generator 213 and the centrifugal drive assembly 215. A platform mounting plate 216 is arranged parallel to the bottom of the separation bin bottom plate 212, four booster spring groups 214 are arranged between the separation bin bottom plate 212 and the platform mounting plate 216, and a vibration generator 213 is also arranged at the bottom of the separation bin bottom plate 212. Therefore, the vibrating centrifugal separation bin 211 and the separation bin bottom plate 212 can vibrate relative to the platform mounting plate 216 through the booster spring group 214 and the vibration generator 213, and a centrifugal drive assembly 215 is also installed on the separation bin bottom plate 212. The centrifugal drive assembly 215 can be a motor, and the power output shaft of the motor passes through the separation bin bottom plate 212 and is connected to the vibrating centrifugal disk 219 installed in the vibrating centrifugal separation bin 211. A mounting seat for mounting the power output shaft of the motor is arranged on the separation bin bottom plate 212, and a bearing can be arranged in the mounting seat. During actual installation, the distance between the separation bin bottom plate 212 and the platform mounting plate 216 can be customized according to needs. If the distance between the separation bin bottom plate 212 and the platform mounting plate 216 is difficult to adapt to the installation of the centrifugal drive assembly 215, a through hole can be opened in the middle of the platform mounting plate 216, and the through hole is the make way hole for the centrifugal drive assembly 215.

[0061] In one embodiment, the vibrating centrifugal separation chamber 211 is preferably a cylindrical structure, and a feed port is formed on the top thereof, and the feed port is used to receive the molten steel sample after the sample breaking process. The molten steel sample after the sample breaking process in the present application includes the upper shell and the lower shell of the molten steel sample, the molten steel sample and the crushed mud ball particles, wherein the crushed mud ball particles are small particles, and the upper shell and the lower shell of the molten steel sample are different from the thickness of the molten steel sample. Therefore, the present application can perform vibrating centrifugal separation on these materials by virtue of their different characteristics.

[0062] During specific application installation, a loading robot can be equipped to automatically insert the sampler mud ball into the molten steel for sampling and then insert the sampler mud ball into the sample breaking device 100 for automatic sample breaking. The material after automatic sample breaking can be discharged from the sample outlet of the sample breaking device 100 into the vibrating centrifugal separation chamber 211.

[0063] In one embodiment, the vibrating centrifugal disk 219 in the present application is a disc-shaped structure, and the height of the upper disk surface gradually increases from the edge of the upper disk surface of the vibrating centrifugal disk 219 to the center of the upper disk surface, that is, the upper surface of the vibrating centrifugal disk 219 is a conical surface with a thin edge and a thick middle. When the sample, the sample shell and the crushed mud particles fall into the vibrating centrifugal separation chamber 211, the sample, the sample shell and the crushed mud particles fall freely into the vibrating centrifugal separation chamber 211 that rotates at a high speed and vibrates at a high frequency, and collide with the vibrating centrifugal disk 219. The sample, the upper shell of the sample, the lower shell of the sample and the crushed mud particles are distributed separately in the vibrating centrifugal disk 219 (the vibrating centrifugal disk 219 is tapered, with a high center and a low edge), and are distributed and slid to the edge of the vibrating centrifugal disk 219 under the action of centrifugal force. The crushed mud particles, the upper shell and the lower shell of the molten steel sample under the action of the high-speed rotating vibrating centrifugal disk 219 are discharged through the discharge port 218 with a limited height under the action of centrifugal force; the thickness difference between the molten steel sample and the sample shell is used to retain the molten steel sample in the vibrating centrifugal separation chamber 211. Therefore, the present application can automatically sort the molten steel sample mixture after the sample is broken, which provides convenience for the subsequent automatic sample picking.

[0064] In one embodiment, in order to guide the sorted materials to the target location, the present application installs a discharge guide assembly 217 on the outer wall of the vibrating centrifugal separation chamber 211, and the discharge guide assembly 217 includes a guide groove arranged at the discharge port 218, and the guide groove is used to receive the upper shell and lower shell of the crushed mud particles and the molten steel sample discharged from the discharge port 218. The guide groove can output the sorted materials to post-processing stations such as collection boxes.

[0065] In one embodiment, the above-mentioned vibrating centrifugal separation chamber 211 is cylindrical, and the separation chamber bottom plate 212 is a square plate. A booster spring group 214 can be set at the four corners of the separation chamber bottom plate 212. At the same time, the platform mounting plate 216 is basically a square plate, but a triangular convex plate is respectively arranged outward on the four sides of the square plate, and the four triangular convex plates are respectively connected to the booster spring group 214. Therefore, the booster spring group 214 is not installed vertically, but is installed at an angle relative to the separation chamber bottom plate 212.

[0066] In one embodiment, the vibrating centrifugal sorting component 210 in the present application is mounted on the frame through a platform mounting plate 216.

[0067] In another embodiment, the vibrating centrifugal sorting component 210 in the present application is slidably connected to the slide rail through the platform mounting plate 216.

If the shearing handle is successful, the material coding information corresponding to the working time is identified and recorded. After completion, the sample after the shearing handle is picked up and the sample after the shearing handle is adjusted and weighed. The weight data is checked and the sample with the corresponding coding information entered is transported to the sample receiving waiting station B or the manual sampling station. If manual sample delivery is required, the sample after the shearing handle is placed in the manual sampling station, and after being cooled by the cooling water at the manual sampling station, it is manually picked up and placed in the sample delivery port A. If automatic To transport the sample, place the sample that has been sheared into the open empty sample box at the sample receiving waiting station B; start the conveyor line 330 to transport it to the sample box switch station C, then start the sample box switch component to press the sample box cover into the sample box, and reset the sample box switch component; start the conveyor line 330 to transport the sample box after the cover is completed to the sample box transfer station D, start the sample box transfer component 350, place the sample box at the sample delivery port A, and the pneumatic sample delivery machine will transport the sample box to the inspection laboratory.
