Description

Technical Field

[0001] The utility model relates to the technical field of granulating devices, and particularly relates to a granulating device capable of continuously preparing microwave dielectric materials. Background Technique

[0002] Microwave dielectric materials refer to materials with specific electromagnetic properties within the microwave frequency range. Microwave is a type of electromagnetic wave, and its frequency is generally between 300 megahertz (MHz) and 300 gigahertz (GHz), corresponding to a wavelength of about 1 millimeter to 1 meter. Microwave dielectric materials are usually used to manufacture microwave devices, antennas, radar systems, communication equipment, etc. Common microwave dielectric materials include, but are not limited to, oxide ceramics, polymers, composite materials, etc. Microwave dielectric materials will be produced into granular form by a granulator, which is beneficial for forming various different styles of material devices in the subsequent process.

[0003] Under the prior art, for example, a granulator is disclosed in a Chinese patent with the publication number CN116328645A, which includes: a rotating drum, with a feed inlet provided on one side thereof, and a plurality of nozzles for discharging liquid materials in the form of liquid particles are evenly provided on the wall of the rotating drum. The diameter size of the rotating drum is set to any size between 90 - 150 mm; a pair of support structures are respectively provided at both ends of the rotating drum and are fixedly connected to the rotating drum respectively. A driving device is installed inside one of the pair of support structures; a heating device is provided inside the rotating drum. The heating device has a length corresponding to the rotating drum, and both ends of the heating device are respectively fixed at both ends of the rotating drum; and a plate is provided below the rotating drum, and the vertical distance from the plate to the rotating drum is set to any size between 2 - 4 mm. The progressive technical effect that can be achieved by the present invention is that the rotation speed of the nozzles is reduced, and correspondingly, the centrifugal force of the liquid drops to be dripped is reduced, so that the dripped liquid drops can have a generally spherical shape.

[0004] Although the above device solves the problem that the particles are flat when the material is generated, in the actual production process, nozzles are evenly distributed on the outer surface of the rotating drum, so that during the production process of the rotating drum, particles may be discharged from both the side and the top, resulting in random scattering of the material and inability to form. Therefore, we propose a granulating device capable of continuously preparing microwave dielectric materials to solve the above problems. Content of the Utility Model

[0005] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by the utility model is as follows:

[0007] A granulating device for continuously preparing microwave dielectric materials, comprising a first support base. A granulating assembly for material forming is arranged on one side of the first support base. A feeding assembly is arranged at one end of the granulating assembly away from the first support base. A conveying table is arranged at the bottom of the granulating assembly. The granulating assembly includes a servo motor. One end of the top of the first support base is sleeved on the surface of the servo motor. The output end of the servo motor is fixedly connected with a rotating disk. A rotating cylinder is fixedly connected to the side of the rotating disk away from the servo motor. A plurality of forming holes for discharging materials are arranged on the surface of the rotating cylinder. A heating cylinder is sleeved in the inner cavity of the rotating cylinder. A shielding cylinder is sleeved on the outer surface of the rotating cylinder. A granule discharging window for controlling the discharging direction of the materials in the heating cylinder is arranged at the bottom of the shielding cylinder. The feeding assembly includes a fixed disk. One end of the rotating cylinder is rotatably connected to the fixed disk. A second support base is fixedly connected to the side of the fixed disk away from the rotating cylinder.

[0008] Preferably, the servo motor is fixedly connected to the first support base, and the axes of the rotating cylinder, the output end of the servo motor and the rotating disk coincide.

[0011] Preferably, the granule discharging window is arranged on the top of the conveying table, and the axes of the shielding cylinder, the rotating cylinder and the heating cylinder coincide.

[0012] Preferably, the fixed disk is arranged on the side of the rotating cylinder away from the first support base, and the first support base and the second support base are symmetrically distributed along the axis of the rotating cylinder.

[0013] Preferably, the side of the fixed disk close to the rotating cylinder is fixedly connected to the heating cylinder, the side of the fixed disk close to the rotating cylinder is fixedly connected to the shielding cylinder, and a feeding channel communicating the gap between the heating cylinder and the rotating cylinder is arranged on the top of the fixed disk.

[0014] Preferably, a shielding ring is sleeved around the fixed disk. The side of the shielding ring close to the rotating cylinder is in contact with and fixedly connected to the rotating cylinder. A funnel is fixedly connected to one side of the shielding ring.

[0015] By adopting the above technical solutions, the beneficial effects obtained by the present utility model are as follows:

[0016] In the present utility model, the support base is used to support and fix the whole device. The granulating assembly is located on one side of the first support base and is used for material forming and granulating. The feeding assembly includes a fixed disk and a rotating cylinder and is used for controlling and guiding the feeding of raw materials. The conveying table is located at the bottom of the granulating assembly and is used for receiving and conveying the granulated materials.

[0017] The fixed disk is connected to the rotating drum. There is a feed channel on the fixed disk. Through this window, microwave dielectric composite materials can be added into the interior of the rotating drum. The shielding ring is in contact with and fixed to the rotating drum. The funnel is rotatable and is used to precisely control the addition of raw materials, preventing the discharge of materials from the feed channel during rotation. The servo motor rotates the rotating drum through the rotating disk.
