Description

Technical Field

[0001] This utility model belongs to the field of composite additive production technology, specifically relating to a flat die granulator with a material surface cooling device. Background Technology

[0002] Currently, most flat die granulators on the market experience increasing heat accumulation during granulation as the running time increases, leading to higher internal temperatures and excessively sticky, clumped granules. To further improve production efficiency and increase output, some manufacturers have added instrument ducts at the granulator outlet for cooling. However, when the granulation volume increases, the material at the outlet still tends to stick together, failing to meet the material cooling requirements. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] This invention proposes a flat die granulator with a material surface cooling device to solve the technical problem of how to rapidly cool the material surface inside the granulator, thereby reducing material adhesion during discharge.

[0005] (II) Technical Solution

[0006] To solve the above-mentioned technical problems, this utility model proposes a flat die granulator with a material surface cooling device. The granulation unit of the flat die granulator has an opening, and an air inlet connector is connected to the opening. The air outlet pipe of the fan is fixedly connected to the air inlet connector. After the flat die granulator is working, the surface of the material in the granulation unit is cooled by the fan.

[0007] Furthermore, holes are made along the tangential direction of the material flow direction inside the granulation unit.

[0008] Furthermore, the external air inlet connector is fixed at the opening with screws.

[0009] Furthermore, the blower is simultaneously connected to the granulation units of multiple flat die granulators.

[0010] Furthermore, the opening diameter is 80mm.

[0011] Furthermore, the blower uses a Roots blower.

[0012] Furthermore, the Roots blower has a power output of 7.5 kW and a maximum flow rate of 3.8 m³ / h. 3 / min.

[0013] Furthermore, as the granulation capacity of the flat die granulator increases, the blower automatically adjusts the air intake to the granulation unit.

[0014] (III) Beneficial Effects

[0015] This invention proposes a flat die granulator with a material surface cooling device. The granulation unit of the flat die granulator has openings, with external air inlets connected to these openings. The air outlet pipe of a blower is fixedly connected to the air inlet. After the flat die granulator starts operating, the blower cools the surface of the material in the granulation unit. This invention is simple, utilizing existing equipment. By openings in the flat die granulator and adding a Roots blower for air intake cooling, the surface of the material can be rapidly cooled inside the granulator. This solves the problem of excessively sticky granulated material causing clumping, thereby reducing the difficulty of subsequent material cooling, alleviating pressure on the granulator, and preventing blockages and shutdowns. It saves manpower and resources, enables continuous production, greatly increases output and work efficiency, reduces labor intensity, improves product quality stability, and eliminates potential production hazards. Attached Figure Description

[0016] Figure 1 This is a schematic diagram illustrating the structure and working principle of the flat die granulator of this utility model. Detailed Implementation

[0017] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0018] This embodiment proposes a flat die granulator with a material surface cooling device, the structure of which is as follows: Figure 1 As shown, on granulation unit 1 of the flat die granulator, an 80mm hole is drilled tangentially along the material flow direction inside the granulation unit using an impact drill. An external air inlet connector is fixed at the hole with screws, and an external Roots blower is added. The outlet pipe of the Roots blower 2 is fixedly connected to the air inlet connector. After the flat die granulator is started, as the granulation volume increases, the air volume of the Roots blower 2 into granulation unit 1 is slowly increased to rapidly cool the surface of the material in granulation unit 1, reduce material adhesion at the outlet, and thus meet the technical requirements.

[0019] In this embodiment, the Roots blower 2 is simultaneously connected to the granulation unit 1 of two flat die granulators, using a 7.5kW Roots blower with a maximum flow rate of 3.8m³ / h. 3 / min, which can meet the air volume requirements of two flat die pellet mills running at the same time.

[0020] This utility model of a flat die granulator has the advantages of simple design, low investment, and easy operation. It enables the surface of the material to be rapidly cooled inside the granulator, solving the problems of excessive stickiness of the granulated material during the production of compound additives, which leads to clumping and difficulty in subsequent material cooling. Furthermore, insufficiently cooled material entering the granulator often causes blockage and shutdown, requiring disassembly and cleaning of the granulator, and in severe cases, damage to the granulator belt. This wastes manpower and resources, delays continuous production, and seriously affects output.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
