Description

Technical Field

[0001] The invention relates to the technical field of petroleum coke blending, and in particular to a batching method for automatic batching of petroleum coke blending. Background Art

[0002] Petroleum coke is a by-product produced in the process of petroleum refining. It is a heavy residue in petroleum refining. It is a solid carbonaceous material formed by heating and cracking crude oil and removing light components. Cracking residues are also selectively added during the production process. Since cracking residues usually contain rich heavy hydrocarbons and aromatics, these components help to improve the thermal effect and efficiency of the reaction.

[0003] In the production of petroleum coke blending, it is necessary to introduce an automated batching device to accurately control the proportions of different raw materials and perform batching operations. For example, a calcining furnace petroleum coke batching device disclosed in application number CN202223591081.6 uses an automated batching device for automatic batching.

[0004] Since petroleum has a complex chemical composition, contains a large amount of high molecular weight hydrocarbons, and has a long carbon chain and a ring structure, the intermolecular force is large; the cracking residue has a high viscosity due to the residual heavy components, such as high molecular weight hydrocarbons, asphaltene, etc., and the condensation reaction at high temperature to generate macromolecular compounds and coke, and the petroleum and cracking residue are usually in a viscous state. Although the existing automatic batching device has a correct proportion during batching, the amount of material entering the blending is less than the amount of material in the hopper due to the high viscosity and poor fluidity of the petroleum and cracking residue. This causes errors and affects the accuracy of batching. The existing automatic batching device does not have measures to prevent the petroleum and cracking residue from sticking in the batching device, and it cannot automatically make up for the sticky raw materials after the petroleum and cracking residue stick in the batching device. Therefore, the present invention proposes a device that can prevent material adhesion and automatically compensate for the material amount according to the batching error. Summary of the invention

[0018] A batching method for petroleum coke blending and automatic batching comprises the following steps:

[0019] S1. Automatically batching and unloading unmixed raw materials through an automatic batching and unloading mechanism, and unloading the unmixed raw materials one by one;

[0020] S2. By using the anti-sticking component, anti-sticking liquid is applied to the inner wall of the containing frame each time the material is unloaded;

[0021] S3, after each unloading, automatically detect whether there is sticky raw material in the containing frame through the detection component;

[0022] S4. When the detection component detects that there is raw material stuck in the containing frame, the detection component detects the weight of the stuck raw material, and then the stuck raw material is replenished by the raw material replenishing mechanism.

[0023] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0024] Through the detection component, the weight of the holding frame and the raw materials in the holding frame can be converted into current signals, and compared with the current signals corresponding to the pre-tested required raw material weight to verify whether the raw materials in the holding frame meet the requirements. More precise weight control can be achieved to ensure the accuracy of material unloading. In addition, the weight of the holding frame after unloading can be converted into current signals, and compared with the current signals corresponding to the weight of the holding frame during the initial detection. If the current signal corresponding to the weight of the holding frame after unloading is large, it means that the raw materials may be adhered to the inner wall of the holding frame. The problem of raw materials adhering to the inner wall of the holding frame can be discovered in time, so as to avoid inaccurate unloading caused by adhesion and deal with it in time.

[0025] When it is detected that raw materials are adhered to the inner wall of the containing frame, the raw material replenishing mechanism can adjust the repulsive force of the third electromagnetic plate on the second permanent magnetic plate according to the current signal converted according to the detected weight of the adhered raw materials, thereby controlling the rising height of the second permanent magnetic plate. Subsequently, the raw materials in the replenishing frame will be replenished into the containing frame. Due to the weight of the raw materials replenished in the replenishing frame, the replenishing frame will be lowered, and then the second conductive block at the bottom of the replenishing frame will contact the first conductive block at the top of the second permanent magnetic plate. Then, the PLC controller will immediately stop injecting raw materials into the replenishing frame, and then the replenished raw materials will be put into the production barrel. After the raw materials are stuck in the containing frame, the amount of the stuck raw materials can be automatically compensated in the production barrel.

[0026] Through the anti-sticking component in the automatic batching and unloading mechanism, during the unloading process of the first push plate and after the unloading and resetting of the first push plate, the anti-sticking liquid will be applied to the inner wall of the containing frame through the smear sponge to prevent the raw materials from adhering to the inner wall of the containing frame, which helps to keep the containing frame clean and reduce the residue problem during each batching, thereby improving the accuracy and consistency of the batching. At the same time, after the containing frame is reset, the sealing plug can be pushed open by the squeezing block to allow the anti-sticking liquid in the replenishing tube to flow into the smearing sponge, so that the smearing sponge can continue to apply the anti-sticking liquid to the inside of the containing frame.

[0049] The specific structure is as follows: the raw material replenishing mechanism 4 also includes a second elastic telescopic rod 43, a third elastic telescopic rod 44, and a third electromagnetic plate 45 which are fixedly connected to the inner bottom wall of the replenishing chamber 41, and the replenishing chamber 41 is opened in the batching box 2, the telescopic end of the second elastic telescopic rod 43 is fixedly connected to the bottom end of the replenishing frame 42, the top end of the third elastic telescopic rod 44 is fixedly connected to a second permanent magnetic plate 46 which is magnetically repelled from the third electromagnetic plate 45, the top end of the second permanent magnetic plate 46 is fixedly connected to a first conductive block 47, and the bottom end of the replenishing frame 42 is fixedly connected to a second conductive block 48 which matches the first conductive block 47. The inner wall of the replenishment frame 42 is fixedly connected with a second electric telescopic rod 49, the telescopic end of the second electric telescopic rod 49 is fixedly connected with a second push plate 410 for discharging materials, the top of the batching box 2 is fixedly connected with a raw material replenishment box 411, the bottom end of the raw material replenishment box 411 is fixedly connected with a discharge pipe 412, and the lower end of the discharge pipe 412 passes through the top of the batching box 2 and extends to the top of the replenishment frame 42, a normally closed solenoid valve is arranged in the discharge pipe 412, the inner top wall of the raw material replenishment box 411 is fixedly connected with a third electric telescopic rod 417, the telescopic end of the third electric telescopic rod 417 is fixedly connected with a lower pressure plate 418.

[0050] Among them, the holding frame 32 and the production cylinder 1 are jointly provided with a second discharge port 413, and the top of the production cylinder 1 is provided with a second telescopic groove 414 and a storage groove which are connected to the second discharge port 413, and a special-shaped baffle plate 415 is slidably connected in the second telescopic groove 414 for blocking the second discharge port 413, and the inner bottom wall of the storage groove and the bottom end of the protruding part of the special-shaped baffle plate 415 are jointly fixedly connected with a fourth electric telescopic rod 416, and the PLC controller is connected with the third electromagnetic plate 45, the first conductive block 47, the second conductive block 48, the second electric telescopic rod 49, the third electric telescopic rod 417, the normally closed solenoid valve, and the fourth electric telescopic rod 416 by electrical signals to form a feeding circuit.

[0051] The working principle of the present invention is as follows:

[0052] First, the PLC controller automatically controls the pump 31 to put the two different raw materials (petroleum and cracking residue) in the storage box 38 into the two holding frames 32 according to the required raw materials. As the raw materials are put into the holding frames 32, the resistance of the sliding rheostat in the detection circuit gradually decreases as the conductive sheet 361 slides on the resistance plate 362 toward the storage box 38. The weight of the holding frame 32 and the raw materials drives the conductive sheet 361 to slide downward on the resistance plate 362. Therefore, the resistance in the detection circuit gradually increases, and the current passing through the detection module gradually decreases. Therefore, the PLC The current monitoring module in the controller monitors the current input to the current monitoring module, and determines the corresponding current value of each raw material by analyzing the pre-tested raw materials. The result of this process will be used to establish a relationship model between the raw material and the current (for example, 10MA current corresponds to 10kg of raw material weight). Then, the current converted from the weight of the pre-tested required raw material and the containing frame 32 is compared with the real-time monitored current signal to determine whether the raw material in the containing frame 32 reaches the pre-set raw material predetermined value. When the predetermined value is not reached, continue to add to the containing frame 32 through the extraction pump 31.

[0053] Then, the two second electromagnetic plates 364 are energized through the PLC controller, so that the two second electromagnetic plates 364 are magnetically attracted to each other to fix the horizontal position of the containing frame 32, and then the first electric telescopic rod 314 is controlled to start through the PLC controller, and the L-shaped baffle plate 313 is driven to move upward by the first electric telescopic rod 314. While the L-shaped baffle plate 313 moves upward, the scraper 312 can scrape the raw material on the surface of the L-shaped baffle plate 313, and then the first electromagnetic plate 341 is energized through the PLC controller, and the repulsive force of the first electromagnetic plate 341 on the first permanent magnet plate 342 is used to make the first push plate 33 push the raw material into the production tube 1 through the first discharge port 310, and then the first electromagnetic plate 341 is controlled to be de-energized through the PLC controller, and then the first push plate 33 is driven to reset by the first spring 343, and at the same time, the first electric telescopic rod 314 is controlled to reset, thereby driving the L-shaped baffle plate 313 to reset.

[0054] During the process of resetting the first pushing plate 33 and the process of pushing and unloading the material by the first pushing plate 33, the anti-sticking liquid can be smeared on the inner wall of the containing frame 32 through the smearing sponge, and in this process, the second electromagnetic plate 364 is controlled to be powered off by the PLC controller, and then the containing frame 32 is reset by the elastic potential energy of the second spring 363. When the containing frame 32 is reset, the extrusion block 356 separates the extrusion sealing plug 354 from the liquid outlet 353, and then the connecting plate 355 drives all the sealing plugs 354 and the sealing column 358 to move upward. Through the upward movement of the sealing column 358, the water pipe 357 can be blocked, so that the anti-sticking liquid in the liquid replenishing box 352 will no longer continue to be injected into the replenishing pipe 351 through the blocking pipe, and the anti-sticking liquid added into the replenishing pipe 351 before the water pipe 357 is blocked will enter the smearing sponge through the liquid outlet 353.

[0055] Since some fine impurities in cracked residue or petroleum may cause tiny dents or scratches on the inner wall of the containing frame 32, even with anti-adhesive liquid, it may cause the petroleum and cracked residue to adhere. The uneven surface or tiny flaws can provide attachment points for these substances, so a large amount of petroleum or cracked residue can be adhered for a long time. When petroleum or cracked residue is adhered to the containing frame 32, the weight of the containing frame 32 and the adhered petroleum or cracked residue will make the conductive sheet 361 unable to reset. Therefore, the current transmitted from the conductive sheet 361 to the PLC controller is monitored by the current monitoring module, and then the detected current is compared with the current corresponding to the containing frame 32 in the initial state. Then, the calculation module in the PLC controller calculates how much petroleum or cracked residue is adhered to the containing frame 32, and then the raw material replenishment mechanism 4 is controlled by the PLC controller to replenish the raw materials. The specific replenishment method is as follows:

[0056] First, the PLC controller controls the repulsion of the third electromagnetic plate 45 on the second permanent magnetic plate 46. The magnitude of the repulsion is that after the raw materials are replenished in the replenishment frame 42, the second conductive block 48 at the bottom of the replenishment frame 42 can better contact the first conductive block 47 at the top of the second permanent magnetic plate 46 due to the weight of the replenished raw materials. Therefore, the repulsion of the second electromagnetic plate 364 is inversely proportional to the weight of the raw materials stuck in the containing frame 32 (i.e., the weight that needs to be replenished);

[0057] Then, the third electric telescopic rod 417 is controlled to start and the normally closed solenoid valve is opened through the PLC controller, and then the third electric telescopic rod 417 drives the lower pressure plate 418 to squeeze the raw material into the replenishment frame 42 through the discharge pipe 412. When the replenishment frame 42 drives the second conductive block 48 to contact the first conductive block 47, the normally closed solenoid valve and the third electric telescopic rod 417 are immediately controlled to close through the PLC controller, and then the fourth electric telescopic rod 416 is controlled to start through the PLC controller, thereby driving the special-shaped baffle plate 415 to move upward, and then opening the second discharge port 413, and then starting the second electric telescopic rod 49, thereby driving the second discharge plate to replenish the raw material into the production cylinder 1, and an alarm that the containing frame 32 needs to be repaired will be reported on the PLC controller.
