Description

Technical Field

[0001] This utility model relates to the field of equipment technology, and in particular to an automatic batching equipment for preparing bonded permanent magnet ferrite. Background Technology

[0002] Bonded permanent magnet 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 processing them through a series of production processes. In the mixing process, each raw material needs to be weighed and mixed together according to the formula in different proportions.

[0003] The old production model involved manually weighing each raw material before pouring it into a mixing tank for high-speed mixing. This model had several drawbacks: it required a large amount of manual labor for weighing and handling materials; the varying proportions of raw materials in each formula also made it prone to human error, affecting the accuracy of the formula; and the raw materials were all powders, generating significant dust during handling and disposal, resulting in substantial air pollution. Therefore, it is necessary to propose a new solution to address these problems. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide an automatic batching device for preparing bonded permanent magnet ferrites. It can effectively solve the problems of the existing mixing process of bonded permanent magnet ferrites requiring manual weighing, which is prone to inaccurate formulation due to human error, resulting in substandard product performance, and the generation of a large amount of dust during the material handling process, causing pollution to the working environment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automated batching device for preparing bonded permanent magnet ferrite includes 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. The vacuum powder separator has a receiving cavity for storing materials and an openable / closeable feeding port connected to the receiving cavity and equipped with a dust collector. Multiple vacuum powder separators are present, all mounted on the working platform and connected to the control module. Multiple buffer silos are also present, all mounted on the frame and connected to the control module. The system consists of multiple interconnected buffer hoppers, each with its input end connected to the corresponding output end of a vacuum powder separator. Multiple feeding devices are also present, each connected to the output end of its corresponding buffer hopper and to the control module. Each feeding device contains a weighing device. A metering hopper is mounted on the frame and connected to the control module; its input end is connected to the output ends of the multiple feeding devices. A mixing device is mounted on the frame and connected to the control module; its input end is connected to the output end of the metering hopper. A discharge device is mounted on the frame and connected to the control module; its input end is connected to the output end of the mixing device.

[0007] As a preferred embodiment, each buffer silo is equipped with a first temperature control module, and the mixing device is equipped with a second temperature control module. There are various raw materials for preparing bonded permanent magnet ferrite, and the activity of each raw material is different at different temperatures. The design of the first temperature control module can preheat the various raw materials at different temperatures, so that the activity of each raw material can be maintained at a near-optimal level in the early stage or early stage of mixing. 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 internal mixing temperature, so that the material can be directly internally mixed after being discharged by the discharge device.

[0008] As a preferred embodiment, at least one of the multiple buffer silos is equipped with a viscometer connected to the control module. The viscosity of the resin matrix is ​​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 use different preparation processes for the same resin, resulting in differences in polymerization degree and other aspects. This causes the viscosity of the resin to vary at the same temperature. The viscometer can monitor the viscosity of the resin matrix in real time, and the operator can adjust the temperature as needed.

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

[0010] As a preferred option, the blower is a Roots blower.

[0011] As a preferred embodiment, the feeding device is a screw feeder.

[0012] As a preferred embodiment, the mixing device is a horizontal mixing device.

[0013] As a preferred embodiment, the discharge device is a screw discharge device.

[0014] As a preferred embodiment, the frame is equipped with a climbing ladder, one end of which is in contact with the ground and the other end of which is connected to the work platform.

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

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0017] By installing a dust collector at the feeding port, the dust can be removed when the operator feeds the material, preventing pollution to the working environment. In addition, each feeding device is equipped with a weighing device, which replaces the traditional manual weighing and feeding of raw materials with automatic weighing, avoiding inaccurate formulas due to human error and improving the product performance compliance rate.

[0028] Please refer to Figure 1As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a frame 10, a vacuum powder separator 20, a buffer silo 30, a feeding device 40, a metering silo 50, a mixing device 60, and a discharging device 70.

[0029] The frame 10 has a work platform 11 and a control module (not shown in the figure) is provided on the frame 10; in this embodiment, a climbing ladder 12 is provided on the frame 10, one end of the climbing ladder 12 is in contact with the ground, and the other end of the climbing ladder 12 is connected to the work platform 11.

[0030] The vacuum powder separator 20 has a receiving cavity 21 for storing materials, and the vacuum powder separator 20 has an openable or closable feeding port 22. The feeding port 22 is connected to the receiving cavity 21 and is equipped with a dust collector 23. The dust collector 23 is a pulse dust collector. There are multiple vacuum powder separators 20, and all multiple vacuum powder separators 20 are set on the working platform 11 and connected to the control module. In this embodiment, the vacuum powder separator 20 is connected to a blower 24. The blower 24 is used to create a vacuum environment to realize vacuum transportation. The blower 24 is a Roots blower.

[0031] There are multiple buffer hoppers 30, each mounted on the frame 10 and connected to the control module. The input terminals of each buffer hopper 30 are connected to the output terminals of the corresponding vacuum powder separator 20. In this embodiment, each buffer hopper 30 is equipped with a first temperature control module 31. The raw materials used to prepare the bonded permanent magnet ferrite are varied, and each raw material exhibits different activities at different temperatures. The first temperature control module 31 is designed to preheat the various raw materials at different temperatures, ensuring that their respective activities are maintained close to optimal levels during the initial or early stages of mixing. In addition, at least one of the multiple buffer silos 30 is equipped with a viscometer (not shown in the figure). The viscometer is connected to the control module. The viscosity of the resin matrix is ​​affected by temperature. The design of the first temperature control module 31 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 degree of polymerization and other aspects will be different, which will cause the viscosity of the resin to 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.

[0032] There are multiple feeding devices 40, each of which is connected to the output end of the corresponding buffer hopper 30 and connected to the control module. Each feeding device 40 is equipped with a weighing device (not shown in the figure). In this embodiment, the feeding device 40 is a spiral feeding device.

[0033] The metering chamber 50 is mounted on the frame 10 and connected to the control module. The input end of the metering chamber 50 is connected to the output end of multiple feeding devices 40.

[0034] The mixing device 60 is mounted on the frame 10 and connected to the control module. The input end of the mixing device 60 is connected to the output end of the metering chamber 50. In this embodiment, the mixing device 60 is equipped with a second temperature control module (not shown in the figure). 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 internal mixing temperature so that the material can be directly internally mixed after being discharged by the discharge device 70. The mixing device 60 is a horizontal mixing device.

[0035] The discharge device 70 is mounted on the frame 10 and connected to the control module. The input end of the discharge device 70 is connected to the output end of the mixing device 60. In this embodiment, the discharge device 70 is a screw discharge device.

[0036] The ingredient preparation method of this embodiment is described in detail below:

[0037] First, the staff inputs the formula and related parameters of iron ore powder, resin matrix, and various additives into the control module. Multiple vacuum powder separators 20 vacuum-feed raw materials to the corresponding buffer silos 30. Then, the control module sends a signal to multiple first temperature control modules 31 to control the temperature of the raw materials in the corresponding buffer silos 30, so that the activity of the raw materials in the buffer silos 30 is maintained at the optimal level. Subsequently, the output end of the buffer silo 30 is opened, and multiple feeding devices 40 feed each raw material quantitatively into the metering silo 50. After feeding is completed, the output end of the metering silo 50 is opened, and each raw material enters the mixing device 60 for mixing and stirring. Then, in the middle of the mixing and stirring, the second temperature control module performs the first temperature control inside the mixing device 60, so that the activity of each raw material is maintained at a good level. In the later stage of the mixing and stirring, the second temperature control module performs the second temperature control inside the mixing device 60, so that the temperature of the mixed raw materials is consistent with the internal mixing temperature. Finally, the discharge device 70 sends the mixed raw materials to external equipment for internal mixing.

[0038] The key design feature of this utility model is:

[0039] By installing a dust collector at the feeding port, the dust can be removed when the operator feeds the material, preventing pollution to the working environment. In addition, each feeding device is equipped with a weighing device, which replaces the traditional manual weighing and feeding of raw materials with automatic weighing, avoiding inaccurate formulas due to human error and improving the product performance compliance rate.

[0040] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
