Description

Technical Field

[0001] The present invention relates to the field of sampling equipment, and in particular to an online sampling device for roasted blocks. Background Art

[0002] Anode blocks, also known as prebaked anode carbon blocks, are made from calcined petroleum coke as the aggregate and coal tar pitch as the binder. After calcination, they develop a stable geometric shape for aluminum electrolytic cell anodes. The calcination process removes moisture and volatiles (such as alkanes and aromatic hydrocarbons in the pitch), resulting in a stable geometric shape and reduced specific resistivity, while also enhancing heat resistance and electrical conductivity. After calcination, samples are collected to test the heat resistance and electrical conductivity of the blocks.

[0003] However, at present, the sampling of anode baked blocks is generally done by random manual sampling by sampling personnel. The sampling process has occupational health hazards such as high dust, sewage discharge, and high labor intensity. In addition, pre-baked anodes are subject to safety risks such as falling and equipment injuries during lifting and forklift transportation. Summary of the Invention

[0004] The present invention aims to provide an online sampling device for calcined blocks, which can automatically sample calcined anode blocks after calcination, thereby reducing the labor intensity of staff and lowering the risks in the sampling process.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an online sampling device for roasting blocks, comprising a mounting plate, on which a drilling module, a breaking module, a clamping module and a sample storage module are arranged; the drilling module comprises a drilling unit and a dust removal unit; the drilling unit comprises a drill rod, which is slidably arranged on the mounting plate; the dust removal unit comprises a dust removal cover, which is slidably arranged on the outer wall of the drill rod and is connected to a negative pressure generator; the mounting plate is slidably arranged above the roasting block and can drive the drilling module, the breaking module and the clamping module to move; sampling is performed through the drilling module, the breaking module and the clamping module, and the taken samples are temporarily stored in the sample storage module.

[0006] The beneficial effects of this solution are as follows: this solution arranges the drilling module, breaking module and clamping module on a mounting plate, which is slidably arranged above the roasting block and can drive the drilling module, breaking module and clamping module to move; when sampling, the relative positions of the roasting block and the drilling module, breaking module and clamping module can be changed by moving the mounting block, so that the drilling module, breaking module and clamping module can be used to perform drilling operations, breaking operations and clamping operations respectively; at the same time, since a dust removal hood is provided on the drill rod, the dust removal hood can be used to collect the dust generated by the drilling operation during the drilling operation to prevent the dust from escaping into the sampling environment and reduce the dust in the sampling operation.

[0007] Furthermore, the drilling unit further comprises a rotary driving member which is slidably arranged on the mounting plate and can drive the drill rod to rotate via an output shaft.

[0008] Beneficial effect: The drill rod is driven to rotate by the rotary drive member to replace manual drilling work, which significantly reduces labor intensity.

[0009] Furthermore, the dust hood includes a guide rod, one end of which is fixedly connected to the dust hood, and the other end of which is mounted on the side wall of the rotating drive member and slidably connected to the side wall of the rotating drive member. The provision of the guide rod helps to regulate the movement trajectory of the dust hood and prevent the dust hood from rotating. Because the dust hood does not rotate and slides smoothly, the negative pressure pipe connected to it is not subjected to additional torque or pulling, thereby effectively preventing the interface from loosening or falling off, and continuously maintaining efficient dust removal performance.

[0010] Furthermore, the drill rod is hollow and connected to compressed air.

[0011] Beneficial effect: The drill rod is set to be hollow and connected to compressed air. When drilling, the drill end of the drill rod can be cooled by compressed air, and the dust drilled by the drill rod can be blown out, making it easier for the dust collector to collect the dust.

[0012] Furthermore, it also includes an air inlet pipe, which is arranged on the side wall of the rotary drive component and connects the compressed air to the drill rod.

[0013] Furthermore, both the drilling module and the clamping module include a lifting assembly, which includes a fixing part and a lifting part. The fixing part is fixedly connected to the mounting block, and the lifting part is slidably arranged on the fixing part. The drilling rig or the clamp is respectively fixed on the lifting part and can slide along the fixing part under the drive of the lifting part.

[0014] Beneficial Effects: By configuring independent lifting assemblies for the drilling and clamping modules, and utilizing a sliding fit between the fixed and lifting components, precise and smooth lifting and lowering of the drill rig and clamp are achieved. This design allows for independent and non-interfering drilling and clamping operations, enhancing operational flexibility and control precision. The lifting assemblies feature a simple structure and reliable operation, shortening cycle times and improving operational efficiency. Furthermore, the modular design facilitates maintenance and replacement, enhancing the stability and scalability of the equipment, making it suitable for highly automated production scenarios.

[0015] Furthermore, the breaking module includes a wedge block, which is slidably arranged on the mounting plate.

[0016] Beneficial effect: When breaking, the breaking module is driven to move to the broken state position through the lateral movement mechanism, so that the free end of the wedge block is coplanar with the sampling ring, and then the cylinder extends to drive the wedge block to insert into the sampling ring, so that the sample column moves away from the wedge block, so that the connection between the sample column and the calcined block is broken, forming a sample independent of the calcined block, and realizing sample breaking.

[0017] In addition, the breaking module is precisely moved to the breaking position through the lateral movement mechanism, so that the wedge block and the sampling ring are coplanar, ensuring accurate alignment of the insertion action; then the cylinder drives the wedge block to insert into the sampling ring, pushing the sample column to move to the distal side, causing a controllable fracture at the connection between it and the calcined block at the stress concentration point, ensuring the integrity and stable separation of the sample, forming an independent sample, avoiding damage or errors caused by manual breaking, improving the consistency and success rate of sampling, and facilitating the accuracy of subsequent testing and the continuity of automated operations.

[0018] Furthermore, the sample storage module includes a sample bin, which is arranged on one side of the product line and fixedly connected to the frame. The clamping module also includes a clamping unit, which includes a finger cylinder and a clamping claw. The finger cylinder is slidably set on the mounting plate through a lifting assembly, and the clamping claw is fixed on the output shaft of the finger cylinder and can be opened and closed under the drive of the finger cylinder.

[0019] When clamping out, the horizontal moving mechanism drives the clamping module to move to the clamping state position, so that the clamping claws are coplanar with the sampling ring, and then the motion mechanism descends to drive the clamping claws to insert into the sampling ring; the clamping claws are driven by the finger cylinder to clamp the sample; the motion mechanism rises to drive the clamping claws to reset, thereby taking out the sample; the horizontal moving mechanism drives the clamping module to move to the sample bin, the motion mechanism descends, the finger cylinder is released, the sample is placed in the sample bin, and the motion mechanism rises and resets.

[0020] By setting up a sample bin fixedly connected to the frame and cooperating with the clamping module, automatic transfer and orderly storage of samples after removal are achieved. When in use, the clamping module is driven by the lateral moving mechanism to move accurately to the clamping position, and the clamping claw is inserted into the sampling ring driven by the motion mechanism. The finger cylinder performs the clamping action to stably grasp the broken sample; then it is lifted and reset, and then moved to the top of the sample bin by the lateral moving mechanism, lowered and released, and the sample is accurately placed in the bin. The whole process has a high degree of automation, and the movement is smooth and reliable, which effectively avoids the loss or contamination of samples during the transfer process, realizes the integrated operation of sampling, clamping and temporary storage, improves sampling efficiency and operation safety, and facilitates subsequent centralized processing and management.

[0021] Furthermore, a guide bearing is provided on the side wall of the rotary driving member, and the guide rod is inserted into the guide bearing on the side wall of the rotary driving member and is slidably connected to the side wall of the rotary driving member through the guide bearing.

[0022] Beneficial effects: The setting of the guide bearing can significantly reduce the friction resistance between the guide rod and the rotating drive component, ensuring that the dust collector can move smoothly and synchronously during the drilling rod lifting process, avoiding jamming; at the same time, the setting of the bearing structure can provide stable guide support, enhance the linearity and repeatability of the dust collector movement, thereby reducing dry friction between metal parts, reducing wear, and improving the overall reliability and durability of the device.

[0025] Example 1 Example 1 is basically as shown in the attached Figure 1-7 As shown, Figure 1-7 The roasted block online sampling device shown is used for sampling the roasted block 100, and includes a frame and a horizontal moving mechanism 210, as shown in FIG. Figure 1 、 Figure 3As shown, the transverse moving mechanism 210 includes a transverse rail 211 and a first mounting plate 212. The transverse rail 211 is fixedly arranged on the rack above the roasting block 100 and is provided with a transverse driving member 213. The first mounting plate 212 is provided with a first mounting position 201, a second mounting position 202 and a third mounting position 203, and the drilling module 220, the breaking module 230 and the taking-out module 240 are fixed through the first mounting position 201, the second mounting position 202 and the third mounting position 203 respectively. The first mounting plate 212 is slidably arranged on the transverse rail 211 and can The transverse driving member 213 is driven to slide to change the relative positions of the drilling module 220, the breaking module 230 and the removal module 240 and the roasting block 100. Specifically, the transverse driving member 213 is a servo motor, and a screw rod is fixed on the output shaft 233 of the servo motor. The free end of the screw rod is rotatably set on the transverse track 211, and the first mounting plate 212 is threadedly connected to the screw rod. Therefore, the rotation of the servo motor drives the first mounting plate 212 to slide on the transverse track 211, thereby driving the drilling module 220, the breaking module 230 and the removal module 240 to slide.

[0026] like Figure 4 、 Figure 5 As shown, the drilling module 220 includes a drilling unit and a dust removal unit. The drilling unit includes a first lifting assembly, which includes a first lifting track 221 and a second mounting plate 222. A screw and a first lifting drive 223 are provided on the first lifting track 221. The screw is rotatably arranged in the first lifting track 221. The first lifting drive 223 is fixed on the first lifting track 221 and can drive the screw to rotate. The second mounting plate 222 is slidably arranged on the first lifting track 221 and is threadedly connected to the screw. A rotating assembly is fixed on the second mounting plate 222. Specifically, the rotating assembly includes a rotating drive 224 and a drill rod 225. The drill rod 225 is rotated by the rotating drive 224 is fixed on the second mounting plate 222 and can rotate under the drive of the rotating drive member 224. In this embodiment, the rotating drive member 224 is a motor, which includes a shell and a drive shaft. The shell is fixedly connected to the second mounting plate 222 by bolts. A guide bearing 229 and an air intake pipe are fixed on the shell, and the air intake pipe is connected to compressed air. The drill rod 225 is rotatably set on the shell and can rotate under the drive shaft. The dust removal unit includes a dust removal cover 226, and a guide rod 228 is fixed on the dust removal cover 226.

The guide rod 228 is slidably set on the outer wall of the rotating drive member 224 through a guide bearing 229.

[0027] During sampling, the rotary drive member 224 rotates to drive the drill rod 225 to rotate; at the same time, compressed air is introduced into the air inlet 227; the negative pressure generator is started, so that the dust hood 226 is connected to the dust collecting negative pressure; the first lifting assembly drives the rotary assembly to descend to perform drilling work, so that a sampling ring 101 is formed on the surface of the roasting block 100, and the roasting block 100 is partially isolated by the sampling ring 101 to form a sample column. When the dust hood 226 contacts the sample surface, the guide rod 228 begins to slide in the guide bearing 229; when the first lifting assembly descends to the set depth, the rotary drive member 224 stops rotating, and at the same time, the first lifting assembly is reset, so that the lower end of the dust hood 226 is away from the surface of the roasting block 100; finally, the introduction of compressed air is stopped, and the negative pressure generator is turned off to stop the generation of the dust collecting negative pressure.

[0028] The breaking module 230 includes a breaking drive and a wedge block 231. The breaking drive is fixed to the second mounting position 202 by bolts and can drive the wedge block 231 to move up and down. Figure 6 As shown, in this embodiment, the breaking drive member is a cylinder including a cylinder body 232 and an output shaft 233. The cylinder body 232 is fixedly connected to the second mounting position 202 by bolts, and the wedge block 231 is fixedly connected to the output shaft 233 by bolts. When breaking, refer to Figure 2 The relative position of the breaking module 230 and the calcined block 100 is changed by the lateral moving mechanism 210, so that the wedge block 231 is located above the sampling ring 101. Then, the breaking drive component is started, and the wedge block 231 is driven downward by the output shaft 233, so that the sample column moves away from the wedge block 231, so that the connection between the sample column and the calcined block 100 is broken, forming a sample independent of the calcined block 100, and completing the sample breaking operation.

[0029] like Figure 7 As shown, the clamping module includes a second lifting assembly and a clamping unit. The second lifting assembly includes a second lifting rail 244, a second lifting drive member 241 and a screw rod. A slider 242 is slidably provided on the second lifting rail 244. The second lifting drive member 241 is fixedly provided on the second lifting rail 244 and can drive the screw rod to rotate. The screw rod is rotatably provided in the second lifting rail 244 and is threadedly connected to the slider 242. When clamping out, the horizontal moving mechanism 210 drives the clamping module to move to the clamping state position, so that the clamping jaw 245 is coplanar with the sampling ring 101, and then the second lifting component is lowered to drive the clamping jaw 245 to insert into the sampling ring 101; the finger cylinder 243 is driven to make the clamping jaw 245 clamp the sample; the second lifting component rises to drive the clamping jaw 245 to reset, thereby taking out the sample.

[0030] Example 2 Based on Example 1, the present invention further includes a sample storage module, which includes a sample bin. The sample bin is fixedly positioned on one side of the production line and fixedly connected to the frame or transverse rail 211. The second lifting assembly ascends, driving the clamping jaws 245 to return to their original position. After the sample is removed, the clamping jaws 245 are driven by the transverse movement mechanism 210 to reach the upper part of the sample bin. The second lifting assembly then drives the clamping jaws 245 downward, releasing the clamping jaws 245 and placing the removed sample into the sample bin. This effectively prevents sample loss or contamination during transfer, achieving an integrated operation of sampling, clamping, and temporary storage, improving sampling efficiency and operational safety, and facilitating subsequent centralized processing and management.

[0031] Example 3 On the basis of Example 2, it also includes a block detection unit, which includes a sensor and a controller. The sensor is fixed on both sides of the product line and can detect the arrival of the roasted block 100. The sensor is electrically connected to the product line and the online sampling device through the controller to form a block detection unit. Figure 8 As shown in the connection relationship, the controller has a built-in control program, and can control the start and stop of the product line and the online sampling device through the control program. Therefore, the online sampling device of Example 1 is linked with the product line through the block detector and the controller to form an online sampling system.

[0032] During operation, the incoming block detection unit detects incoming block information through a sensor and sends the detected incoming block information to the controller. After receiving the signal from the sensor, the controller controls the production line through a built-in control program to suspend the conveying operation of the roasted blocks 100 and control the online sampling device to start sampling. After sampling is completed, the production line resumes the conveying operation of the roasted blocks 100 and waits for the next sampling, thus realizing unattended online sampling of roasted blocks 100.
