Description

Technical Field

[0001] This solution relates to the field of sampling equipment, specifically to an online sampling device for calcined blocks. Background Technology

[0002] Prebaked anode blocks, also known as calcined anode carbon blocks, are carbon blocks made from calcined petroleum coke as aggregate and coal tar pitch as binder. After calcination, they form a stable geometric shape and are used as anode materials for aluminum electrolysis cells. The calcination process removes moisture and volatiles (such as alkanes and aromatics in the pitch), allowing the carbon blocks to form a stable geometric shape and reducing their resistivity, while simultaneously enhancing their heat resistance and electrical conductivity. After calcination, samples of the anode blocks need to be taken to test their heat resistance and electrical conductivity.

[0003] However, at present, the sampling of anode calcination blocks is generally carried out by sampling personnel through random manual sampling. The sampling process has occupational health hazards such as high dust, sewage discharge, and high labor intensity. In addition, there are safety risks such as falling and equipment injury during hoisting and forklift transportation of prebaked anodes. Utility Model Content

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

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an online sampling device for calcined blocks, including a mounting plate, on which a drilling module, a breaking module, a clamping module, and a sample storage module are provided. The drilling module includes a drilling unit and a dust removal unit. The drilling unit includes a drill rod, which is slidably mounted on the mounting plate. The dust removal unit includes a dust removal hood, which is slidably mounted on the outer wall of the drill rod and connected to a negative pressure generator. The mounting plate is slidably mounted above the calcined 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 extracted samples are temporarily stored in the sample storage module.

[0006] The beneficial effects of this solution are as follows: This solution sets the drilling module, breaking module, and clamping module on the mounting plate. The mounting plate is slidably positioned above the calcining block and can move the drilling module, breaking module, and clamping module. During sampling, the relative positions of the calcining block and the drilling module, breaking module, and clamping module can be changed by moving the mounting block, thereby allowing the drilling, breaking, and clamping operations to be performed using the drilling module, breaking module, and clamping module respectively. At the same time, since a dust hood is installed on the drill rod, the dust generated during drilling operations can be collected using the dust hood, preventing dust from escaping into the sampling environment and reducing dust during sampling operations.

[0007] Furthermore, the drilling unit also includes a rotary drive component, which is slidably mounted on the mounting plate and can drive the drill rod to rotate via the output shaft.

[0008] Beneficial effects: The rotary drive mechanism rotates the drill rod, replacing manual drilling and significantly reducing labor intensity.

[0009] Furthermore, the dust collector hood also includes a guide rod. One end of the guide rod is fixedly connected to the dust collector hood, and the other end is hung on the side wall of the rotary drive component and slidably connected to the side wall of the rotary drive component. The guide rod helps to regulate the movement trajectory of the dust collector hood and prevent it from rotating. Because the dust collector hood does not rotate and slides smoothly, the negative pressure pipe connected to it will not be subjected to additional torque or pulling, thus effectively preventing the interface from loosening or falling off and continuously maintaining high-efficiency dust removal performance.

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

[0011] Beneficial effects: By making the drill rod hollow and connected to compressed air, the drill bit end can be cooled by compressed air during drilling, and the dust drilled out during the drilling operation can be blown out, making it easier for the dust collection hood to collect the dust.

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

[0013] Furthermore, both the drilling module and the clamping module include a lifting assembly. The lifting assembly includes a fixing part and a lifting part. The fixing part is fixedly connected to the mounting block, and the lifting part is slidably mounted on the fixing part. The drilling rig or clamp is 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 components for the drilling and clamping modules, and utilizing the sliding fit between the fixed and lifting components, precise and stable lifting movements of the drilling rig and clamping fixture are achieved. This design ensures that drilling and clamping actions are independent and do not interfere with each other, improving operational flexibility and control precision. The lifting component has a simple structure and reliable operation, which helps to shorten the action cycle and improve work efficiency. At the same time, the modular design facilitates maintenance and replacement, enhances the stability and scalability of the equipment, and is suitable for highly automated production scenarios.

[0015] Furthermore, the break-off module includes a wedge block that is slidably mounted on the mounting plate.

[0016] Beneficial effects: When the sample is broken, the lateral moving mechanism drives the breaking module to the broken position, so that the free end of the wedge block is coplanar with the sampling ring. Then the cylinder extends and drives the wedge block to insert into the sampling ring, causing the sample column to move away from the wedge block. This causes the connection between the sample column and the calcining block to break, forming a sample independent of the calcining block, thus achieving sample breaking.

[0017] In addition, the lateral movement mechanism precisely moves the breaking module to the breaking position, making the wedge block and the sampling ring 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 the side away, causing it to fracture controllably at the stress concentration point where it connects with the calcined block, 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 benefiting the accuracy of subsequent testing and the continuity of automated operation.

[0018] Furthermore, the sample storage module includes a sample compartment located on one side of the product line and fixedly connected to the frame. The gripping module also includes a gripping unit, which includes a finger cylinder and a gripper. The finger cylinder is slidably mounted on the mounting plate via a lifting assembly, and the gripper is fixed on the output shaft of the finger cylinder and can open and close under the drive of the finger cylinder.

[0019] During extraction, the lateral movement mechanism moves the extraction module to the extraction position, making the grippers coplanar with the sampling ring. Then, the motion mechanism descends, causing the grippers to insert into the sampling ring. The finger cylinder drives the grippers to clamp the sample. The motion mechanism rises, causing the grippers to reset, thus removing the sample. The lateral movement mechanism moves the extraction module to the sample chamber, the motion mechanism descends, the finger cylinder releases, the sample is placed into the sample chamber, and the motion mechanism rises to reset.

[0020] By setting up a sample chamber that is fixedly connected to the frame and working in conjunction with the clamping module, the automatic transfer and orderly storage of samples after extraction are achieved. In use, the clamping module moves precisely to the clamping position under the drive of the lateral moving mechanism. The gripper is inserted into the sampling ring under the drive of the motion mechanism, and 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 chamber by the lateral moving mechanism. It then descends and releases the gripper to accurately place the sample into the chamber. The whole process is highly automated, smooth and reliable, effectively avoiding sample loss or contamination during the transfer process. It realizes the integrated operation of sampling, clamping, and temporary storage, improving sampling efficiency and operational safety, and facilitating subsequent centralized processing and management.

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

[0022] Beneficial effects: By setting up the guide bearing, the frictional resistance between the guide rod and the rotary drive component can be significantly reduced, ensuring that the dust hood can move smoothly and synchronously during the drilling rod lifting process, avoiding jamming; at the same time, the bearing structure can provide stable guiding support, enhancing the linearity of the dust hood's movement and the repeatability of its positioning accuracy; thereby reducing dry friction between metal parts, reducing wear, and improving the overall reliability and durability of the device.

Detailed Implementation

[0032] Example 1

[0033] Example 1 is basically as shown in the appendix. Figure 1-7As shown, Figure 1-7 The online sampling device for calcined blocks shown is used for sampling calcined blocks 100, and includes a frame and a lateral moving mechanism 210, such as... Figure 1 , Figure 3 As shown, the lateral moving mechanism 210 includes a lateral track 211 and a first mounting plate 212. The lateral track 211 is fixedly mounted on a frame above the calcining block 100 and is equipped with a lateral driving component 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. A drilling module 220, a breaking module 230, and a taking-out module 240 are respectively fixed to the first mounting position 201, the second mounting position 202, and the third mounting position 203. The first mounting plate 212 is slidably mounted on the lateral track 211 and can... The lateral drive component 213 slides downward to change the relative positions of the drilling module 220, the breaking module 230, and the extraction module 240 with the calcining block 100. Specifically, the lateral drive component 213 is a servo motor, and a lead screw is fixed on the output shaft 233 of the servo motor. The free end of the lead screw is rotatably mounted on the lateral track 211. The first mounting plate 212 is threadedly connected to the lead screw. Thus, the rotation of the servo motor drives the first mounting plate 212 to slide on the lateral track 211, thereby causing the drilling module 220, the breaking module 230, and the extraction module 240 to slide.

[0034] 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 rail 221 and a second mounting plate 222. A lead screw and a first lifting drive 223 are mounted on the first lifting rail 221. The lead screw is rotatably mounted within the first lifting rail 221, and the first lifting drive 223 is fixed to the first lifting rail 221 and can drive the lead screw to rotate. The second mounting plate 222 is slidably mounted on the first lifting rail 221 and threadedly connected to the lead 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 driven by the rotating drive... 224 is fixed on the second mounting plate 222 and can rotate under the drive of the rotary drive component 224. In this embodiment, the rotary drive component 224 is a motor. The motor includes a housing and a drive shaft. The housing is fixedly connected to the second mounting plate 222 by bolts. A guide bearing 229 and an air inlet pipe are fixed on the housing. The air inlet pipe is connected to compressed air. The drill rod 225 is rotatably mounted on the housing and can rotate under the drive of the drive shaft. The dust removal unit includes a dust removal hood 226. A guide rod 228 is fixed on the dust removal hood 226. The dust removal hood is slidably mounted on the outer wall of the drill rod 225 and is connected to a negative pressure generator. The guide rod 228 is slidably mounted on the outer wall of the rotary drive component 224 through the guide bearing 229.

[0035] During sampling, the rotary drive 224 rotates, driving the drill rod 225 to rotate; simultaneously, compressed air is introduced through the air inlet 227; the negative pressure generator is activated, causing the dust collector 226 to connect to the dust collection negative pressure; the first lifting assembly drives the rotary assembly to descend for drilling, forming a sampling ring 101 on the surface of the calcined block 100, and partially isolating the calcined block 100 through the sampling ring 101 to form a sample column. When the dust collector 226 contacts the sample surface, the guide rod 228 begins to slide within the guide bearing 229; when the first lifting assembly descends to the set depth, the rotary drive 224 stops rotating, and simultaneously, the first lifting assembly resets, causing the lower end of the dust collector 226 to move away from the surface of the calcined block 100; finally, the compressed air supply is stopped, and the negative pressure generator is turned off to stop the generation of dust collection negative pressure.

[0036] The break-off module 230 includes a break-off drive component and a wedge block 231. The break-off drive component is fixed to the second mounting position 202 by bolts and can drive the wedge block 231 to move up and down, such as... Figure 6 As shown, in this embodiment, the breaking drive 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 calcining 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 is activated, and the wedge block 231 is moved down through 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 calcining block 100 is broken, forming a sample independent of the calcining block 100, thus realizing the sample breaking operation.

[0037] 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 component 241, and a lead screw. A slider 242 is slidably disposed on the second lifting rail 244. The second lifting drive component 241 is fixedly disposed on the second lifting rail 244 and can drive the lead screw to rotate. The lead screw is rotatably disposed within the second lifting rail 244 and is threadedly connected to the slider 242.

[0038] When the sample is removed, the lateral moving mechanism 210 moves the removal module to the removal position, making the gripper 245 coplanar with the sampling ring 101. Then, the second lifting component lowers to insert the gripper 245 into the sampling ring 101. The finger cylinder 243 drives the gripper 245 to clamp the sample. The second lifting component rises to reset the gripper 245, thereby removing the sample.

[0039] Example 2

[0040] Based on Embodiment 1, a sample storage module is also included. This module includes a sample compartment, which is fixedly located on one side of the product line and fixedly connected to the frame or transverse track 211. The second lifting assembly rises, causing the gripper 245 to reset. After the sample is removed, it moves to above the sample compartment under the action of the transverse moving mechanism 210. The second lifting assembly then drives the gripper 245 downwards, releasing it and placing the removed sample into the sample compartment. This effectively avoids sample loss or contamination during transfer, achieving integrated sampling, gripping, and temporary storage operations, improving sampling efficiency and operational safety, and facilitating subsequent centralized processing and management.

[0041] Example 3

[0042] Based on Embodiment 2, an incoming block detection unit is also included. This unit comprises a sensor and a controller. The sensor is fixed on both sides of the production line and can detect the arrival of the calcined block 100. The controller is electrically connected to both the production line and the online sampling device, forming a [structure as described above]. Figure 8 The connection relationship shown is such that the controller has a built-in control program, which can control the start and stop of the product line and the online sampling device. Thus, 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.

[0043] In operation, the incoming block detection unit detects the incoming block information through sensors and sends the detected information to the controller. Upon receiving the signal from the sensors, the controller uses its built-in control program to pause the conveying operation of the calcined block 100 on the production line and activates the online sampling device to perform sampling. After sampling is completed, the conveying operation of the calcined block 100 on the production line resumes, awaiting the next sampling, thus achieving unattended online sampling of the calcined block 100.
