Description

Technical Field

[0001] The utility model relates to a granulator, in particular to a cooling device of a single-screw granulator. Background Art

[0002] New materials refer to newly developed or developing structural materials with excellent performance and functional materials with special properties. It covers multiple fields, including special rubber and other polymer materials, engineering plastics, metal structural materials, composite new materials, superconducting materials, smart materials, magnetic materials, nanomaterials, etc. These new materials have various properties, such as high temperature stability, high strength, high transparency, high temperature resistance, energy saving and environmental protection. Among them, the production process of engineering plastics is to mix the raw materials, and then process the mixed raw materials into plastic particles through a single screw granulator.

[0003] The single screw granulator includes a feeding device, a screw extruder, a cooling device, a drying device and a pelletizing device. The raw material is processed into a long strip by the screw extruder and then transmitted to the cooling device to cool the raw material. Most of the existing cooling devices are mainly water-cooled, and some cooling devices will cooperate with air cooling to cool the water body to achieve a better cooling effect. However, since the cooling path of the existing cooling mechanism is often long, this leads to a long air duct path. In addition, air outlets need to be set along the cooling path of the cooling mechanism, which leads to a large loss of wind during transmission, resulting in the air outlet at the farther end often having little air volume. As a result, this structure cannot play a good cooling role when facing a structure with a longer cooling path, thereby affecting the processing quality of the raw material. Based on the above problems, the present invention was conceived. Utility Model Content

[0006] By adopting the above technical solution, the water in the cooling water tank flows into the head end heat dissipation water tank, and then the water falls down along several heat dissipation water tanks in sequence under the stepped heat dissipation water tank structure with gravity. When the water passes through the drop heat dissipation gap, the contact area with the air is increased to achieve better heat exchange and achieve better heat dissipation effect. The air cooling component is then used to dissipate and cool the heat dissipation water tank and the water flowing through the drop heat dissipation gap, so that the structure can achieve better cooling effect, so as to adapt to more severe processing conditions, make it more practical and improve the processing quality of raw materials. The circulating water pump is set to realize the circulation of water.

[0008] By adopting the above technical solution, the heat of the water in the heat sink is transferred to the heat sink fins, and the heat exchange surface is increased through the heat sink fins to improve the heat exchange efficiency, thereby cooperating with the heat sink fan to achieve better cooling.

[0009] It is further configured as follows: a silencer pad is provided at a position where the heat dissipation water trough receives the water outflow from the previous heat dissipation water trough, and the silencer pad is detachably fixedly connected to the heat dissipation water trough.

[0010] By adopting the above technical solution, the provision of the sound-absorbing pads can reduce the noise generated when the water body falls, thereby providing workers with a more comfortable working environment.

[0011] It is further configured as follows: it includes a placement groove arranged in the heat dissipation water tank and having an installation opening, and a stopper formed in the installation opening and limiting the silencer pad from escaping from the placement groove, the silencer pad is escaping from the placement groove by deformation, and the placement groove is communicated with the inner cavity of the heat dissipation water tank where it is set.

[0012] By adopting the above technical solution, the placement groove cooperates with the stop block to realize the detachable fixation of the silencer pad, which has a simple structure and convenient disassembly and assembly operations.

[0013] It is further configured as follows: it includes a water outlet arranged at the bottom of the placement groove, the water outlet is located inside the inner cavity of the heat dissipation groove and is attached to the inner cavity side wall of the heat dissipation groove, and the bottom of the placement groove is gradually inclined downward toward one side of the inner cavity side wall of the heat dissipation groove attached to the water outlet to form an inclined portion.

[0014] By adopting the above technical solution, this arrangement enables the water entering the placement tank to flow into the inner cavity of the heat dissipation water tank along the inner cavity side wall of the heat dissipation water tank, thereby further reducing the generation of noise.

[0015] It is further configured as follows: a plurality of heat-conducting fins are arranged in the heat-dissipating water tank provided with the heat-dissipating fins, the plurality of heat-conducting fins correspond to the plurality of heat-dissipating fins one by one, and the heat-conducting fins are sealed and pass through the heat-dissipating water tank to be integrally connected with the heat-dissipating fins.

[0016] By adopting the above technical solution, the contact area with the water body is increased by setting up heat-conducting fins, so that the heat in the water body can be quickly conducted to the heat dissipation fins through the heat-conducting fins, thereby further improving the heat conduction efficiency and further improving the cooling effect of the equipment.

[0017] In summary, the utility model has the following beneficial effects: the utility model can achieve a better cooling effect, thereby adapting to more severe processing conditions, making it more practical and improving the processing quality of raw materials. BRIEF DESCRIPTION OF THE DRAWINGS
