Description

Technical Field

[0001] This utility model belongs to the field of cold pressing molding technology of coke powder, and specifically relates to a stable demolding coke powder cold pressing molding machine. Background Technology

[0002] Currently, in the field of coke powder forming technology, briquetting machines generally adopt high-pressure forming, forcing coke powder particles into shape by applying extremely high linear pressure. While this method can guarantee basic forming results, it has significant drawbacks: insufficient pressure leads to difficulty in demolding; high-pressure forming significantly increases energy consumption and raises equipment operating costs; and for materials with added binders, the increased viscosity easily causes them to adhere firmly to the briquetting sockets, resulting in poor demolding, low yield, and frequent shutdowns for mold cleaning, severely impacting production efficiency. Therefore, there is an urgent need for a cold-pressing coke powder forming machine that can ensure uniform mixing of the binder and achieve stable demolding. Utility Model Content

[0003] The purpose of this invention is to provide a stable demolding coke powder cold pressing molding machine to solve the problems of poor material demolding, low yield, and frequent machine shutdowns for mold cleaning in existing coke powder cold pressing molding machines.

[0004] The technical solution of this utility model is: a stable release agent cold pressing molding machine for coke powder, including a frame, a hopper, a ball pressing roller motor, and two sets of ball pressing assemblies arranged in parallel on the frame. The ball pressing assembly includes a reducer, a ball pressing roller, and a roller shaft. The ball pressing roller is mounted on the roller shaft, and the roller shaft is connected to the reducer. The ball pressing roller motor is connected to the two reducers respectively. It also includes a release agent spraying system, which includes a liquid storage tank, atomizing nozzles, and a metering pump. The liquid storage tank is connected to a main outlet pipe, and the metering pump is installed on the main outlet pipe. Two branch pipes are connected in parallel at the end of the main outlet pipe. Two atomizing nozzles are provided and connected to the two branch pipes respectively. The two atomizing nozzles are respectively positioned opposite the two ball pressing rollers.

[0005] As a further improvement of this utility model, a flow meter is provided on the main outlet pipe.

[0006] As a further improvement of this utility model, the surface of the ball pressing roller is provided with multiple ball pits, which are inverted drip shape.

[0007] As a further improvement of this utility model, the depth of the ball socket to the width of the opening is 1.2-1.5:1.

[0008] As a further improvement of this utility model, the surface of the ball socket is polished and chrome-plated.

[0009] As a further improvement of this utility model, a stirring device is provided inside the liquid storage tank.

[0010] As a further improvement of this utility model, it also includes a feeding mechanism, which includes a feeding shaft, multiple feeding rods and a feeding motor. The feeding shaft is connected to the output end of the feeding motor, and the feeding rods are installed on the surface of the feeding shaft and located inside the hopper.

[0011] The beneficial effects of this utility model are: 1. This utility model sprays a release agent onto the ball-pressing roller through a release agent spraying system, forming a uniform isolation film on the surface of the ball socket, effectively preventing adhesive adhesion and improving the success rate of demolding.

[0012] 2. This invention designs the ball socket in an inverted teardrop shape and proposes an optimal ratio of socket depth to opening width, reducing demolding resistance. The combination of the inverted teardrop-shaped ball socket and the mold release agent spraying system ensures stable demolding, significantly improves yield, avoids frequent downtime for mold cleaning, and achieves efficient, continuous, and stable production.

[0013] 3. This utility model has a reasonable structure. The release agent spraying system is directly installed on the original frame without changing the core structure of the briquetting machine, which is easy to implement and has strong practicality. Attached Figure Description

Each ball-forming assembly includes a reducer 3, ball-forming rollers 16, and roller shafts 9. The ball-forming rollers 16 are mounted on the roller shafts 9, which are connected to the reducers 3 via a ball-forming roller drive shaft 5. The ball-forming roller motor 2 is connected to both reducers 3. A screw conveyor 32 is installed inside the hopper 34. The discharge end of the screw conveyor 32 is connected to a conveying cylinder 36. A discharge nozzle 29 is located at the end of the conveying cylinder 36, above the extrusion line between the two ball-forming rollers 16. The ball-forming rollers 16 are fixed to the roller shafts 9, which are supported and fixed to the frame 1 by a supporting roller shaft bearing seat 6 and a pressure-bearing roller shaft bearing seat 11. One of the pressure-bearing roller shaft bearing seats 11 is connected to a roller pressure cylinder 13 and can slide up and down along a pressure-bearing bearing mounting bracket 14, thereby providing adjustable roller pressure to the two ball-forming rollers 16. The ball pressing roller 16 is fixed to the ball pressing roller mounting section of the roller shaft 9 by the clamping nut 18. This cantilever structure eliminates the need to remove the bearing seat when disassembling the ball pressing roller 16, greatly improving maintenance efficiency. Figure 1 In order to clearly show the ball pressing roller 16, the hopper 34 is not drawn.

[0018] This utility model relates to a stable de-molding coke powder cold pressing molding machine, such as... Figure 1-5 As shown, based on the existing coke powder cold pressing molding machine, a release agent spraying system is also included. The release agent spraying system is set on the feeding side of the frame 1 and includes a liquid storage tank 21, atomizing nozzles 19 and a metering pump 27. The liquid storage tank 21 is connected to a liquid outlet main pipe 37. The metering pump 27 is set on the liquid outlet main pipe 37. Two branch pipes 26 are connected in parallel at the end of the liquid outlet main pipe 37. Valves 25 are provided on the branch pipes 26. Two atomizing nozzles 19 are provided and are respectively connected to the two branch pipes 26. The two atomizing nozzles 19 are respectively opposite to the two pressing rollers 16.

[0019] A flow meter 20 is installed on the main outlet pipe 37 to monitor the actual flow rate of the release agent.

[0020] The surfaces of the two ball-pressing rollers 16 are provided with multiple matching ball sockets 7, which are inverted drip shape.

[0021] The depth-to-opening width ratio of the ball socket 7 is 1.2-1.5:1, which can reduce demolding resistance. In this embodiment, the depth-to-opening width ratio of the ball socket 7 is designed to be 1.3:1.

[0022] The surface of ball socket 7 is polished and chrome-plated.

[0023] The storage tank 21 is equipped with a stirring device 24.

[0024] It also includes a material feeding mechanism, which comprises a feeding shaft 30, multiple feeding rods 31, and a feeding motor 33. The feeding shaft 30 is connected to the output end of the feeding motor 33, and the feeding rods 31 are mounted on the surface of the feeding shaft 30 and located inside the hopper 34. The feeding mechanism can break up material bridging inside the hopper 34, ensuring uniform material feeding.

[0025] In this embodiment, the metering pump 27 and the feeding motor 33 are connected to the control unit inherent in the coke powder cold pressing molding machine for easy control. In this embodiment, the metering pump 27 is also linked with the ball pressing roller motor 2, which can automatically adjust the spraying frequency and dosage of the release agent according to the rotation speed of the ball pressing roller 16, so as to achieve synchronous and precise control.

[0026] The power for the operation of the ball pressing roller 16 is provided by the ball pressing roller motor 2. After being reduced in speed by two reducers 3, the power is transmitted to the two roller shafts 9 through the ball pressing roller drive shaft 5, thereby driving the two ball pressing rollers 16 to rotate in opposite directions.

[0027] The storage tank 21 contains the release agent, and the stirring device 24 prevents the release agent from settling. When the ball-pressing roller motor 2 is running, the metering pump 27 is also started. The release agent is accurately metered by the metering pump 27 and delivered to the atomizing nozzle 19. The two atomizing nozzles 19 are respectively positioned opposite the two ball-pressing rollers 16, and the spray direction of the atomizing nozzles 19 ensures that the release agent can uniformly cover the entire inner wall of the ball socket 7 in a mist.

[0028] The combination of the release agent spraying system and the inverted drip-shaped ball socket 7 ensures stable demolding, significantly improves the yield, avoids frequent machine shutdowns for mold cleaning, and achieves efficient, continuous, and stable production.
