Description

Technical Field

[0001] The present invention relates to the field of equipment technology, in particular to an automatic batching device and a batching method for preparing bonded permanent ferrite. Background Art

[0002] Bonded permanent ferrite is made by mixing iron ore powder, resin matrix and various additives, such as epoxy soybean oil coupling agent, calcium stearate, zinc stearate and other main materials in a certain proportion, and then processed through a series of production processes. Among them, in the mixing process, each raw material needs to be mixed together after weighing according to the formula and in different proportions.

[0003] The old production model involved manually weighing each raw material and then pouring it into a mixing drum for high-speed mixing. This model had the disadvantages of requiring a significant amount of manual labor to weigh and remove the raw materials. Because the raw material ratios varied for each recipe, this was prone to human error, affecting the accuracy of the recipe. Furthermore, since the raw materials were all powdered, the handling process generated a lot of dust, significantly polluting the air. Therefore, a new solution was necessary to address these issues. Summary of the Invention

[0004] In view of this, the present invention addresses the deficiencies in the prior art, and its main purpose is to provide an automatic batching equipment for preparing bonded permanent magnet ferrites, which can effectively solve the problems that the existing mixing process of bonded permanent magnet ferrites requires manual weighing, which is prone to inaccurate formulas due to human errors, resulting in substandard product performance, and a large amount of dust is generated during the loading and unloading process, causing pollution to the working environment.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] An automatic batching equipment for preparing bonded permanent magnet ferrite, comprising a frame, a vacuum powder separator, a buffer silo, a feeding device, a metering silo, a mixing device and a discharging device; the frame has a working platform, and a control module is provided on the frame; the vacuum powder separator has a storage cavity for storing materials, and the vacuum powder separator is provided with a feeding port that can be opened or closed, the feeding port is connected to the storage cavity and is provided with a dust collector, the vacuum powder separator is multiple, and the multiple vacuum powder separators are all arranged on the working platform and connected to the control module; the cache silos are also multiple, and the multiple cache silos are all arranged on the frame and connected to the control module The blocks are connected, and the input ends of the multiple buffer silos are connected to the output ends of the corresponding vacuum powder separators; there are also multiple feeding devices, and the multiple feeding devices are connected to the output ends of the corresponding buffer silos and connected to the control module, and each feeding device is provided with a weighing device; the metering silo is arranged on the rack and connected to the control module, and the input end of the metering silo is connected to the output ends of the multiple feeding devices; the mixing device is arranged on the rack and connected to the control module, and the input end of the mixing device is connected to the output end of the metering silo; the discharging device is arranged on the rack and connected to the control module, and the input end of the discharging device is connected to the output end of the mixing device.

[0007] As a preferred solution, a first temperature control module is provided in each buffer silo, and a second temperature control module is provided in the mixing device. There are a variety of raw materials for preparing bonded permanent ferrites, and the activity of each raw material at different temperatures is different. The design of the first temperature control module can first preheat the various raw materials at different temperatures, so that the activity of each raw material in the initial or early stage of mixing can be maintained at a level close to the optimal level. The design of the second temperature control module is to maintain the activity of each raw material at a better level in the middle stage of mixing. At the same time, in the later stage of mixing, the temperature of the material is heated to the mixing temperature, so that the material can be directly mixed after being discharged through the discharging device.

[0008] As a preferred solution, at least one of the multiple buffer silos is provided with a viscometer, which is connected to the control module. The viscosity of the resin matrix will be affected by temperature. The design of the first temperature control module can adjust the viscosity of the resin matrix by adjusting the temperature of the resin matrix. However, different manufacturers have different preparation processes for the same resin, and their polymerization degree and other aspects will be different, so that the viscosity of the resin will be different at the same temperature. The viscometer can monitor the viscosity of the resin matrix in real time, and the staff can adjust the temperature according to the situation.

[0009] As a preferred solution, the vacuum separator is connected to a fan.

[0015] As a preferred solution, the dust collector is a pulse dust collector.

[0016] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0017] By installing a dust collector at the feeding port, the dust collector can remove dust when the operator discharges the material to prevent pollution to the working environment. In addition, each feeding device is equipped with a weighing device, and the traditional manual weighing and discharging of raw materials is replaced by automatic weighing, avoiding inaccurate formulas due to human errors and improving the product performance compliance rate.

There are multiple raw materials for preparing bonded permanent ferrites, and the activity of each raw material at different temperatures is different. The design of the first temperature control module 31 can preheat the various raw materials at different temperatures first, so that the activity of each raw material in the initial or early stage of mixing can be maintained at a level close to the optimal level. Flat; in addition, among the multiple buffer silos 30, at least one buffer silo 30 is provided with a viscometer (not shown in the figure), which is connected to the control module.
