Description

Technical Field

[0001] The utility model relates to an intelligent metering atomizing device for ball mill additives, belonging to the technical field of additive metering. Background Art

[0002] Inorganic non-metallic powder dispersant is a chemical additive that improves the grinding effect and performance of non-metallic powders, helps to improve the wettability of powders and reduce the viscosity of slurry. Dispersants attach to the surface of particles to generate electrostatic repulsion and steric hindrance, thereby improving the dispersion stability of powders. Dispersants can increase the impact of grinding media on powders and improve grinding, thereby improving grinding efficiency and reducing the energy consumption required for grinding. Dispersants can improve the stability of finished products and prevent product flocculation.

[0003] However, currently, when adding inorganic powder dispersants, they are mainly added manually, measured manually, and added in the form of liquid. The coating of the additive and the powder is not sufficient, resulting in unstable product quality. Summary of the invention

[0004] The utility model aims to disclose an intelligent metering atomization device for ball mill additives in order to solve the problem that the additive addition method causes insufficient coating of the additives and powder and unstable product quality.

[0005] The technical solution for realizing the utility model is a ball mill additive intelligent metering atomization device, comprising an air compressor, an electromagnetic pump, a flow sensor, an atomizing nozzle, an additive barrel and a main control cabinet; the atomizing nozzle is installed at the feed end of the horizontal ball mill body; the electromagnetic pump inlet is connected to the additive barrel through a pipeline, and the additive is pumped from the additive barrel, the electromagnetic pump outlet is connected to the flow sensor through the additive pipeline, and is connected to the atomizing nozzle through the flow sensor; the power cord of the air compressor is connected to the main control cabinet; the output end of the air compressor is connected to the atomizing nozzle and the additive barrel through a compressed air pipeline, respectively, to provide spray air pressure for the atomizing nozzle and positive pressure for the additive barrel; the main control cabinet is connected to the electromagnetic pump and the flow sensor, respectively.

[0006] The flow sensor is a volumetric flow sensor.

[0007] The working process of the intelligent metering atomization device for ball mill additives of the utility model is as follows: when additives need to be added to the ball mill body, the required amount of additives is input on the main control cabinet, and the main control cabinet starts the air compressor and the electromagnetic pump, and the air compressor and the electromagnetic pump work together to extract the additives in the additive barrel through the additive pipeline, and reach the atomizing nozzle after passing through the flow sensor, and the compressed air reaches the atomizing nozzle at the same time through the compressed air pipeline, and mixes with the additives at the atomizing nozzle into mist and sprays out through the atomizing nozzle, and evenly merges with the powder. When the amount of additives reaches the set required amount, the flow sensor transmits the signal to the main control cabinet, and the main control cabinet will turn off the electromagnetic pump to end the extraction and transmission of the additives.

[0008] Working principle: The flow sensor used in this utility model is a volumetric flow sensor. The pulses of the volumetric flow sensor are accumulated by the PLC (programmable logic controller). When the accumulated additive reaches the set value, the electromagnetic pump is immediately turned off to complete the additive addition work. If the set additive dosage cannot be reached for a long time due to nozzle blockage, the additive barrel is out of additives, etc., the PLC will report a fault after the timing reaches a certain time.

[0009] The beneficial effects of the utility model are as follows: the utility model can intelligently measure the dosage of the additive and accurately grasp the addition amount by adopting a PLC programmable logic controller; after the additive is atomized and added, it is more fully coated with the powder, which can achieve better dispersion, modification and other effects, and ensure stable product quality; by adopting intelligent control, more labor costs can be saved and work efficiency is greatly improved.
