Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1, the present embodiment provides a high-precision dosing system for a rare earth stabilizer, comprising: the device comprises a proportioning bin 1, a plurality of raw material bins 2 arranged in parallel and a metering screw 3 positioned at the bottom of each raw material bin 2; wherein each raw material bin 2 is suitable for storing different types of materials; the metering screw 3 is suitable for metering the discharge amount of the materials in the corresponding raw material bin 2; and the proportioning bins 1 are respectively connected with the metering screws 3 through corresponding material conveying pipes 4 so as to convey the materials to the proportioning bins 1.

Optionally, each material conveying pipe 4 is provided with a switching valve 41 for selecting materials to enter the proportioning bin 1.

Alternatively, the batching bin, such as but not limited to a weighing hopper, is provided with a conventional batching module, such as an electronic scale.

Since the metering screw 3, the feed delivery pipe 4, the switching valve 41, the roots blower 5 and the like corresponding to each raw material bin 2 have the same structure, only some reference numerals are shown in fig. 1.

The high-precision metering and batching system for the rare earth stabilizer realizes simultaneous metering and batching of various materials through the plurality of raw material bins and the corresponding metering modules which are arranged in parallel, and the metering and batching of single materials are upgraded to simultaneous metering and batching of various raw materials, so that the batching efficiency is improved; the discharge amount of materials in the corresponding raw material bin is measured by the measuring screw, the measuring screw is added on a conventional measuring system, the precision of a conventional measuring module is generally less than or equal to 5kg, and the measuring precision after the measuring screw is added is less than or equal to 0.2 kg; the accuracy of measurement is greatly improved.

Optionally, as shown in fig. 1, a roots blower 5 is arranged on the proportioning bin 1, so that the proportioning bin 1 generates negative pressure; when the switching valve 41 is opened, the materials flow out of the raw material bin 2 under the action of negative pressure, sequentially pass through the corresponding metering screw 3 and the material conveying pipe 4, and finally enter the proportioning bin 1. Through negative pressure conveying material, can avoid the material to remain in the conveying pipeline, also can avoid the time delay action of defeated material, further improve the accuracy of measurement.

Further, as shown in fig. 1, the metering screw 3 is adapted to be driven by a variable frequency motor 31; when the discharge amount of the material reaches a set value, the variable frequency motor 31 is suitable for reducing the rotating speed of the metering screw 3 so as to reduce the discharge speed of the material.

In this embodiment, the inverter motor is adapted to be controlled by a control module, such as but not limited to an industrial control board or a PLC module, and the industrial control board may be a MYD-C7Z010/20 industrial control board. The set value can be 90% of the required dosage value, the control module controls the variable frequency motor to reduce the rotating speed of the metering screw so as to control the actual discharge amount and meet the requirement of metering precision; when the discharge amount of the material metered by the metering screw meets the requirement, the control module stops the variable frequency motor from rotating, the material stops flowing out of the metering screw at the moment, and the Roots blower and the switching valve are still in an open state through a delay circuit arranged in the control module, so that all the material remaining in the conveying pipe is sucked into the proportioning bin; and then the control module closes the Roots blower and the switching valve, and the batching process is finished.

In summary, the high-precision metering and batching system for the rare earth stabilizer realizes simultaneous metering and batching of various materials through the plurality of raw material bins and the corresponding metering modules which are arranged in parallel, and the metering and batching of a single material is upgraded to the simultaneous metering and batching of various raw materials, so that the batching efficiency is improved; the discharge amount of the materials in the corresponding raw material bin is measured by the measuring screw, and the measuring screw is added on a conventional measuring system, so that the measuring accuracy is greatly improved; the Roots blower is used for generating negative pressure to convey materials, so that the materials can be prevented from remaining in the conveying pipe, the delay action of conveying is avoided, and the metering accuracy is further improved. Therefore, this high accuracy measurement feed proportioning system for rare earth stabilizer has advantages such as batching speed is fast, the measurement accuracy is high, batching efficiency height, is suitable for the multiple material simultaneous measurement ratio in the rare earth stabilizer batching.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention.
