DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0031] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0032] In industrial production, calcium carbonate as an important inorganic filler, its particle size control directly affects the product performance, superfine calcium carbonate usually refers to the particle size of 1 microns below the powder material, widely used in rubber, plastics, coatings, papermaking and other industries, the accuracy of the material ratio in the production process of such materials is extremely high, the addition error of trace components may lead to the dispersibility, whiteness or mechanical properties of the final product significantly decreased, in order to meet the fine production demand, automatic batching device gradually replaces the traditional manual operation, becomes the key equipment in modern calcium carbonate production line.

[0033] The existing automatic batching device is mainly divided into static batching system and dynamic batching system according to the working principle. The static batching system adopts batch weighing method, and the raw material metering is completed by cooperating with the silo through multiple weighing sensors. For example, a certain type of equipment is equipped with six independent silos, and a high-precision strain weighing sensor is installed at the bottom of each silo. During operation, the central control system starts the screw conveyor or vibrating feeder according to the preset formula, and automatically closes the valve when the weighing value reaches the set threshold. This type of equipment has a relatively simple structure and low maintenance cost, but it has the efficiency bottleneck caused by intermittent operation, especially in large-scale production lines with a capacity of more than 5 tons per hour, frequent start and stop may cause equipment wear and tear.

[0034] The dynamic batching system adopts continuous metering method, and the typical structure includes double-tube screw metering scale, impact plate flowmeter and other continuous feeding devices. A certain enterprise's loss-in-weight metering system calculates the material flow rate by real-time monitoring of the hopper weight change rate, and adjusts the motor speed through algorithm to achieve a flow control accuracy of ±0.5%. This type of system is widely used in ultrafine calcium carbonate production lines for rubber, as it can meet the needs of continuous and stable addition of auxiliary materials such as carbon black and coupling agent. However, the dynamic system is sensitive to the flowability of the material, and when dealing with materials with strong hygroscopicity, problems such as bridging and wall sticking may occur, which requires additional configuration of vibration arch breaking device or pneumatic flow assisting equipment.

[0035] From the equipment structure layout, the existing automatic batching device adopts modular design concept. The basic configuration usually includes five parts: raw material storage silo, conveying mechanism, metering unit, mixing device and control system. The storage silo is usually designed with a conical bottom to promote material flow, and the silo body material is selected according to the material characteristics, such as 304 stainless steel or lining with high polymer material. The common types of conveying mechanism include screw conveyor, belt conveyor and pneumatic conveying system, among which the screw conveyor is the most widely used due to its good sealing performance and strong adaptability. An improved screw structure described in a certain patent literature optimizes the blade spacing and speed matching, reducing the calcium carbonate powder conveying speed fluctuation range from ±15% to ±7%, significantly improving the proportioning stability.

[0036] The metering unit, as the core component, has experienced the evolution process from mechanical scale, electronic scale to intelligent sensor. The current mainstream equipment generally adopts multi-sensor fusion technology, such as combining weighing sensor with microwave moisture meter to simultaneously detect the moisture content of raw materials during metering and automatically compensate the proportioning parameters. A certain type of batching scale is equipped with four cantilever beam sensors symmetrically arranged around the weighing platform, which can eliminate mechanical vibration interference through digital filtering technology. In the working condition where the environmental vibration amplitude is less than 0.5g, the single weighing error can be controlled within 0.05%. However, for ultrafine powders with particle size less than 10 microns, electrostatic adsorption effect may cause a weighing deviation of about 0.2% to 0.8%, and some manufacturers alleviate this problem by spraying conductive coating on the surface of the metering hopper.

[0037] The control system is usually composed of PLC and industrial computer, and equipped with special software to realize formula management, process monitoring and data tracing. Some systems integrate OPC communication protocol, which can be seamlessly connected with DCS system and support remote modification of process parameters. The human-machine interface is usually designed as a touch screen operation panel, with basic functions such as formula storage capacity of no less than 200 groups and historical data saving period of more than 180 days. Some high-end models introduce machine learning algorithms to automatically optimize the unloading sequence and conveying speed parameters based on historical production data, which can improve the overall batching efficiency by about 12% to 18%.

[0038] In specific application scenarios, different industries have different needs for batching devices. For example, plastic masterbatch production requires simultaneous handling of calcium carbonate powder and liquid additives, and the supporting equipment needs to add liquid metering pumps and static mixers; the paint industry pays more attention to the synchronous and accurate addition of color paste and filler, and usually uses a multi-channel parallel metering system. An eight-station batching device used in a ceramic glaze production line has an independent dust removal unit at each station, and the overall sealing level reaches IP65, effectively solving the problem of ultra-fine powder dusting. Paper coating calcium carbonate production lines often need to handle high-viscosity slurry with a solid content of 65% to 75%, so the corresponding batching system needs to be equipped with a large-torque mixer and a high-pressure cleaning device.

[0039] There are still some aspects that need to be improved in existing technology. First, the adaptability of material characteristics is insufficient. When handling mixed materials with a bulk density difference of more than 30%, the error of existing volumetric metering devices will increase significantly. Second, equipment cleaning and maintenance is inconvenient, especially when handling solidified resins, which usually requires 2-3 hours of downtime for disassembly and cleaning. Third, the system has limited expandability, with most devices having no more than 4 reserved interfaces, making it difficult to meet the process change requirements of new product development. Some experimental data shows that when the number of formula raw materials increases from 5 to 8, the metering period of the traditional batching system will increase by 40%, and the dynamic accuracy will decrease by about 0.3 percentage points.

[0040] Recent technological improvements have mainly focused on intelligence and integration. Some researchers have introduced machine vision into powder flow monitoring, which can real-time correct the feeding amount by analyzing the cross-sectional images of the material on the conveying belt. Another scheme proposes a gas-solid two-phase flow batching concept, which uses Venturi effect to improve the stability of ultra-fine powder conveying. An innovative design uses three-dimensional printing technology to manufacture special-shaped spiral blades with self-cleaning function, which can reduce material residue by 85% after testing. These technological advancements make it possible for ultra-fine calcium carbonate production to develop towards higher precision and lower energy consumption, but further reliability verification is still needed before large-scale industrial application.
