Description

Technical Field

[0001] This invention relates to the field of energy production technology, specifically to a production equipment for recovering coke powder to produce coke briquettes. Background Technology

[0002] Coking coal (coke briquettes) is typically used as a substandard metallurgical coke product. It is characterized by poor strength, poor permeability, and poor high-temperature performance. Therefore, coking coal briquettes are a very important energy product, and their production is usually very important. Coke powder is the undersize material of coke and is also one of the raw materials for preparing coking coal briquettes. The preparation process is usually called coke powder reprocessing. In the current situation of tight coal supply in China, coke powder can be reprocessed and utilized to increase the value of coke fines and save some coking coal.

[0003] In traditional preparation methods, coke powder is prepared by manual landfilling, pressure impact, and the use of coagulant aids in conjunction with appropriate molds. This method is relatively stable, but the coal powder is light and easily generates ash, which has a significant impact on the health of operators. In addition, different coagulant aids are required for different particle sizes of coke powder, and different particle sizes also require different dry distillation times. These problems cannot be solved manually. Summary of the Invention

[0004] The purpose of this invention is to provide a method and equipment for preparing coke powder from coke powder, in order to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The production equipment includes a mixing mechanism with an extrusion port. A conveyor belt assembly is located at the extrusion port, and an ash collection box is located at the end of the conveyor belt assembly furthest from the mixing mechanism. A dispersing screen is installed inside the ash collection box, and a dispersing roller is installed on the screen. A distillation tower is located at the output end of the ash collection box, and a steam washing assembly is installed on the distillation tower. A discharge port is located on the distillation tower, and a mixing box is located on the discharge port. A dosing pipe is installed on the mixing box, and a forming machine is located at the bottom of the forming machine. A pressure device is installed on the recovery plate, and a return pipe is installed on the pressure device, connecting to the mixing box. A combination feedback box is located on the mixing box, and the combination feedback box is electrically connected to the dosing pipe and the mixing box via wires. When preparing coking coal, it is first necessary to... To process coke powder, it is fed into a mixing mechanism, which crushes and transports the powder. The crushed coke powder is then fed onto a conveyor belt, which carries it into an ash collection box for stratification and screening. The screened coke powder is then sent to a dry distillation tower, where it undergoes dry distillation to remove organic matter. A gas washing unit washes away the organic gases generated during the dry distillation process. The dried coke powder is then sent to a mixing box, where a coagulant is added via a dosing pipe. The coke powder is then fed into a molding machine, where it is formed into coke pellets. Any unformed coke powder is sent back to the mixing box for further mixing with added chemicals.

[0007] The mixing mechanism includes a mixing box containing a mixing motor. A mixing roller is mounted on the output end of the mixing motor, and multiple crushing blades are mounted on the mixing roller. The end of the mixing roller furthest from the mixing motor output end is rotatably connected to the mixing box. An extrusion port is located on the mixing box. During mixing, the mixing motor drives the mixing roller to rotate, and the mixing roller drives the mixing blades to surge and compress within the mixing box, thus crushing the coke powder and preventing it from clumping due to moisture. Subsequently, under the action of the mixing blades, the coke powder is conveyed to the vicinity of the conveyor belt assembly, which receives the crushed coke powder and awaits further transport.

[0008] The conveyor belt assembly includes a climbing frame equipped with a lifting motor. A conveyor wheel and a secondary conveyor wheel are rotatably connected to the climbing frame. A climbing pulley is wound around the conveyor wheel and secondary conveyor wheel, and anti-roll plates are rotatably connected to the climbing pulley. The end of the climbing frame away from the mixing tank is connected to the ash collection box. Each anti-roll plate intermittently slides into contact with the ash collection box. The lifting motor drives the transmission wheel to rotate. Under the action of the climbing pulley, the secondary conveyor wheel provides support and transmission, while the anti-roll plates prevent coke powder from falling back. Subsequently, the climbing pulley delivers the coke powder into the ash collection box, and the anti-roll plates also contact the ash collection box, thus shaking off any adhering coke powder.

[0009] A vibrating motor is installed inside the ash collection box, with a vibrating cam at the output end of the motor. A vibrating plate is also installed inside the ash collection box, with the vibrating cam intermittently sliding in contact with the upper surface of the vibrating plate. A layered screen plate is installed at the bottom of the ash collection box, with a feeding motor on the layered screen plate. Multiple conveying plates are installed at the output end of the feeding motor, with each conveying plate sliding in contact with its corresponding layered screen plate. When the climbing belt pulley feeds coke powder into the ash collection box, a large amount of coal ash will be generated. At this time, the vibrating motor will drive the vibrating cam to rotate, causing the vibrating plate to vibrate, thus shaking the coke powder ash into the ash collection box. The coke powder will also fall onto the dispersing roller, thus avoiding accumulation, and finally onto the layered screen plate. The layered screen plate separates coke powder of different particle sizes, and the feeding motor will drive the conveying plate to slide on the layered screen plate, sending coke powder of different particle sizes into the dry distillation towers at different heights.

[0010] The distillation tower is equipped with layered pipes, each connected to a corresponding layered sieve plate. A high-temperature generator is installed inside the distillation tower, with a heat transfer plate on top of the generator. A centralized processing tray is located at the bottom of the distillation tower, with a discharge valve at its bottom. The discharge valve is connected to the outlet. Coke powder of different particle sizes enters the distillation tower through the layered pipes, and the high-temperature generator heats the heat transfer plate. The distilled coke powder is then fed into the centralized processing tray, where it awaits discharge. The discharge valve then sends the coke powder into a mixing box for further processing.

[0011] The mixing chamber is equipped with a sealing cover, which is connected to the discharge port on the discharge valve. A cooling plate is installed inside the mixing chamber, containing a cooling component. A mixing motor is also installed inside the mixing chamber, with a rotating frame at its output end. A forming machine contains a forming motor and forming rollers, with the motor's output end connected to the rollers. The forming rollers have multiple forming holes, each with a sliding pressure plate. A pressure spring is installed between the pressure plate and the forming hole. Coke powder is fed into the mixing chamber from the sealing cover. The mixing motor then drives the rotating frame to rotate, pulverizing and mixing the coke powder. The cooling component then thoroughly cools the coke powder and reagents. The mixed coke powder then enters the forming machine from the mixing chamber. The forming motor in the forming machine drives the forming rollers to rotate, and the forming holes on the rollers collect the coke powder, forming coke pellets.

[0012] The molding machine is also equipped with a cutting plate. An extrusion roller is rotatably connected to the end of the cutting plate near the output port of the molding machine. The extrusion roller slides in contact with the molding roller. A pressure device is set at the bottom of the cutting plate. The pressure device includes a pressure blower and a polymerization tank. The polymerization tank is connected to the return pipe. Coke powder and coagulant will be fed into the cutting plate, and the extrusion roller and the molding roller will cooperate to extrude the coke powder in the molding hole. The unfinished coke powder will be sent into the polymerization tank. The pressure blower in the molding machine will send the coke powder into the feed and return pipe.

[0013] A blocking feedback plate is installed inside the combined feedback box, which is rotatably connected to the combined feedback box. A feedback resistor is installed inside the combined feedback box, and a feedback sleeve is slidably connected to the blocking feedback plate. The feedback sleeve is fitted onto the feedback resistor and makes sliding contact with the feedback resistor. A screw feeder is installed inside the dosing pipe. The feedback sleeve, feedback resistor, mixing motor, and screw feeder are electrically connected. During the feeding process, the blocking feedback plate will be impacted by coke powder, and the blocking feedback plate will rotate, thereby driving the feedback sleeve to move. The feedback sleeve will also slide on the feedback resistor, thereby generating a change in current. At this time, it indicates that the reagent is insufficient and needs to be replenished. At the same time, the rotation speed of the mixing motor is accelerated, so as to ensure that the coagulant is fully mixed and improve the yield of coke preparation.

[0014] A method for recovering coke powder to prepare coke briquettes, the method comprising:

[0015] S1. The initial raw materials are initially crushed. The stirring motor drives the stirring roller to rotate, crushing and transporting the raw materials at the same time.

[0016] S2. The ash collection box will screen the coke powder, and the screened coke powder will be sent into the dry distillation tower.

[0017] S3. The dry distillation tower performs stratified dry distillation on the screened raw material and simultaneously performs steam washing;

[0018] S4. The coke powder is fed into the mixing box, where it is cooled down sufficiently and stirred again, while a coagulant aid is added in a timely manner.

[0019] S5. The forming motor inside the forming machine drives the forming rollers to rotate, collect coke powder and extrude it to complete the coke briquettes;

[0020] S6. Recover unconsolidated coke ash, and then the core mechanism provides feedback on the quality of the unconsolidated material to adjust the dosage ratio of the coagulant aid.

[0021] S7. Perform stamping again.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention adopts a structural component with automatic conveying and automatic ash removal. Through the conveyor belt assembly, coke dust is stably fed into the ash removal box, where it is stably collected and simultaneously removed, reducing the risk of coke dust escaping.

[0024] 2. This invention employs a structural component that automatically sieves and selects the distillation time and number of cycles, which can effectively avoid the problem of excessively long or short distillation time for coke powder of different particle sizes, improve the success rate of coke powder distillation, and also make the prepared coke more stable.

[0025] 3. This invention employs an automatic detection and feedback structure for unformed coke powder. It can use the quantity and quality of unformed coke powder to provide feedback on adhesion, adjust the ratio of coagulant to coke powder, and regulate the mixing speed and degree, thereby improving the yield of coke powder.
