Description

Technical Field

[0001] The utility model belongs to the technical field of powder material conveying in a green anode manufacturing process, and particularly relates to a system for eliminating material accumulation in the green anode manufacturing process. Background Art

[0002] Ball mill powder is a crucial component of green anode products. It fills the gaps between various calcined coke and anode scrap particles during the production process. The ball mill powder batching bin stores powder less than 0.075mm after ball milling. During the weighing process, several types of arches are formed: meshing arches, formed when intermeshing particles reach a state of force equilibrium; compression arches, caused by the increased strength of agglomerates due to the weight of the powder; and bonding arches, formed when moisture or static electricity, caused by the grinding process, enhances the adhesion between particles and between particles and the bin walls.

[0003] To address the arching phenomenon that occurs during production, if the taper and shape of the silo discharge port cannot be changed, we generally use the following methods to reduce powder arching: shortening the powder storage time, especially properly arranging production before a shutdown for maintenance, ensuring that the ball mill powder batching silo stores as little or no powder as possible during the shutdown to prevent arching when production is restarted; manually hammering the outer wall of the powder silo to improve discharge speed; and closing the ball mill inlet pipe opening on rainy days to reduce the entry of humid air into the ball mill and reduce material moisture. Although these measures and operations can alleviate the problem of low discharge efficiency to a certain extent, the equipment cannot automatically eliminate arching. Utility Model Content

[0004] The utility model aims to provide a system for eliminating material arching during green anode manufacturing, thereby solving the problem that powder material at a hopper discharge port is prone to arching during green anode product production.

[0005] The technical solution adopted by the utility model is: a system for eliminating material arching during the green anode manufacturing process, comprising multiple sets of air disc devices, one side of the multiple air disc devices is connected to an air distribution pipe, and the front section of the air distribution pipe is connected to a pneumatic unit;

[0006] The pneumatic unit includes a ball valve, a filter pressure reducing valve, a solenoid valve, and a control circuit. The ball valve is installed in front of the filter pressure reducing valve, and the filter pressure reducing valve is installed in front of the solenoid valve. The solenoid valve is connected to a control circuit, and the control circuit automatically controls the action of the solenoid valve after the unloading program is started. The ball valve, filter pressure reducing valve, and solenoid valve are connected by threaded connection through a seamless steel pipe b, and compressed air is passed into the seamless steel pipe b and is connected to the air distribution pipe; the air distribution pipe is fixed around the outer wall of the silo and can supply compressed air to multiple sets of air disc devices.

[0007] The utility model is also characterized in that:

[0008] Preferably, one side of the plurality of air disc devices is connected to an air distribution pipe, and the air distribution pipe can be adjusted and fixed in position according to the installation position of the air disc device, so that the air disc device can be adjusted and added.

[0009] Preferably, the gas distribution pipe includes a plurality of branch pipes, the pipe openings of which are equipped with quick-connect connectors a, and the gas distribution pipe is connected to the gas disc device via the quick-connect connector a.

The air passes through the air disc device and flows along the silo wall to reduce the friction between the material in the silo and the silo wall. At the same time, the air disc device will generate violent high-frequency vibrations due to the introduction of air, completely destroying the arch generated by the material, and promoting the downward flow of the silo material, so that there is no need for manual knocking, thereby effectively improving the unloading efficiency.

[0011] Preferably, the solenoid valve is connected to a control circuit, which automatically controls the action of the solenoid valve after the blanking program is started, and can control the on and off of the compressed air pipeline, so that this method of eliminating arch accumulation can be automated.

[0012] Preferably, the filter pressure reducing valve is connected to the electromagnetic valve through a seamless steel pipe thread, so that the compressed air can be dried and the pressure can be adjusted in time.

[0013] Preferably, the ball valve is connected to the filter pressure reducing valve through a seamless steel pipe thread, so that the subsequent components of the ball valve can be easily replaced and repaired.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] 1. This automated system eliminates material arching. An air disc is installed near the discharge port at the bottom of the powder silo. The control circuit drives the solenoid valve of the compressed air pipeline. The compressed air is transmitted to the air disc through the pipeline. The air disc vibrates at a high frequency under the action of the gas, promoting the downward flow of the silo material, thereby effectively solving the problem of poor fluidity of ball mill powder discharge.

[0016] 2. This automation eliminates the material arch system, reduces the labor intensity of job personnel, and reduces the job operation adjustment tasks, thereby reducing the workload of workshop production organization and coordination and improving production stability.
