Description

Technical Field

[0001] The utility model belongs to residual pole weighing, and particularly relates to a residual pole online weighing device and residual pole processing equipment. Background Art

[0002] In the production process of aluminum electrolytic anodes, production formula and process control are particularly important for anode quality, and the quality of anodes directly affects their use in electrolytic cells. The quality of anodes is directly based on the weight of the returned anode scraps from the electrolytic cell. If the weight of the returned anode scraps exceeds the range of process control, the production process or formula needs to be readjusted to make the anode product quality meet the required standards. Inaccurate weight calculation directly affects the judgment of anode quality. The traditional weighing method is to count the weight of a batch of guide rod groups (including aluminum guide rods, steel claws, and explosive blocks), calculate the average weight of a batch of guide rod groups as a subtrahend, and then weigh the weight of the anode scrap group as a subtrahend. The subtrahend in the above weighing method is variable, such as corrosion of the steel claw body, loss of the aluminum guide rod, adhesion of the electrolyte, etc. The conclusion drawn is not accurate enough, making the conclusion not referenceable, affecting production quality. In addition, due to the large weight of the returned anode scraps, conventional weighing requires a lot of manpower and material resources, resulting in low weighing efficiency and high cost.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1As shown, the utility model proposes an online weighing device for residual poles, comprising: a transport member 1 for transporting a target object, a grabbing unit 2 for grabbing and transporting a residual pole block 5, a weighing unit 3 and a processing unit 4 for weighing the weight of the target object, one end of the grabbing unit 2 is slidably arranged on the transport member 1, and the other end of the grabbing unit 2 grabs the residual pole block 5, the weighing unit is arranged on the transport member 1 to weigh the total weight of the grabbing unit 2 and the residual pole block 5 before transportation, and to weigh the single weight of the grabbing unit 2 after the residual pole block 5 is transported to the press 6 via the transport member 1, the processing unit 4 is connected to the weighing unit 3 to receive the weight information transmitted successively by the weighing unit 3, and the processing unit 4 is used to record the number of times the residual pole block 5 is transported, and to make a difference between the total weight and the single weight received successively. The difference between the total weight and the individual weight can be calculated by the processing unit 4 to obtain the weight of the residual pole block 5. Since the weight of the residual pole block 5 is different from the existing calculation method, the problem of inaccurate weighing due to the loss of the grabbing unit 2 is avoided, and weighing and calculating the residual pole block 5 by the processing unit 4 is more convenient and simple, which saves costs. It should be noted that the existing weighing method requires batch weighing of the grabbing member 222 and the residual pole blocks 5 on the grabbing member 222 and taking the average of the symmetrical results. Due to wear between the grabbing members 222, inaccurate weighing results will occur. Based on this, the utility model completely avoids the above-mentioned weighing method, making the weighed weight result more accurate and the weighed weight result more referenceable, thereby improving the production quality.

[0025] In addition, the processing unit 4 records the weight of the butted pole block 5 calculated for the first time as N1 until the last result as M1, and calculates the total mass of the butted pole block 5 by adding up N1 to M1.

[0026] like Figure 1 He Ru Figure 2As shown, in one embodiment, the weighing unit 3 includes a first weighing piece 31 for weighing the total weight of the grabbing unit 2 and the residual pole block 5 and a second weighing piece 32 for weighing the single weight of the grabbing unit 2. The first weighing piece 31 is arranged at the inlet end of the transport member 1, and the second weighing piece 32 is arranged at the outlet end of the transport member 1. The press 6 is below the transport member 1 and is located between the inlet end and the outlet end of the transport member 1. The first weighing piece 31 and the second weighing piece 32 are respectively connected to the processing unit 4. It should be noted that when the grabbing unit 2 is transported to the first weighing piece 31, the first weighing piece 31 can weigh the total weight of the grabbing unit 2 and the residual pole block 5, and the grabbing unit 2 continues to move on the transport piece 1. The grabbing unit 2 will move to the press 6 and place the residual pole block 5 on the press 6. After that, the grabbing unit 2 is transported on the transport piece 1 to the first weighing piece 31 to weigh the weight of the grabbing unit 2. The processing unit 4 receives the total weight and the weight of a single grabbing unit 2, and calculates the weight of the residual pole block 5. Moreover, the grabbing unit 2 records the weight of the residual pole block 5 once after passing through the first weighing piece 31 and the second weighing piece 32.

[0027] In one embodiment, the transport member 1 is a catenary rail. Optionally, the transport member 1 is suspended above the press 6, and the transport member 1 can also be other slide rails that can slide the pulley, mainly to enable the grabbing unit 2 to slide or move on the transport member 1.

The processing unit 4 also includes a display for displaying numbers, and the display is connected to the calculation module to display the total weight of the grasping unit 2 and the residual pole block 5 weighed, as well as the individual weight of the grasping unit 2, and the difference between the total weight and the individual weight on the display, which is convenient for spot checks, inspections or manual records. Optionally, the calculation module is a central processing unit that can receive data and calculate data.

[0030] In one embodiment, the grabbing unit 2 includes a connecting portion 21 for sliding and a grabbing portion 22 for grabbing the residual pole block 5, one end of the connecting portion 21 is slidably disposed on the transport member 1, and the other end of the connecting portion 21 is connected to the grabbing portion 22. The connecting portion 21 can not only realize its movement on the transport member 1, but also drive the grabbing portion 22 to move together, so that the grabbing unit 2 and the residual pole block 5 can be weighed by the weighing unit 3 on the transport member 1. This transportation method of the grabbing unit 2 is more convenient and efficient.

Optionally, the connecting frame 212 may be a U-shaped structure, and the two inner side walls of the connecting frame 212 are hinged to the outer side wall of a bearing on the sliding wheel 211, so that the sliding wheel 211 drives the connecting frame 212 to move.

[0032] In one embodiment, the gripping portion 22 includes a connecting rod 221 and a gripping member 222, one end of the connecting rod 221 is connected to the connecting portion 21, and the other end of the connecting rod 221 is connected to the gripping member 222.

The specific adsorption structure may be a vacuum suction cup or a magnetic suction cup, and both the vacuum suction cup and the magnetic suction cup may be existing suction cups. The gripping member 222 may be a clamping gripper with a clamping function, for example, two clamping plates that are cross-arranged and rotatably arranged form a clamping surface at one end, and a spring is provided at the other end. When the clamping surface clamps an object, the springs at the other ends of the two clamping plates are compressed, and a clamping force is formed under the action of the elastic force to clamp the residual pole block 5.
