Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, in particular to a furan resin heating and temperature control device. Background Art

[0002] 3D sand printers, based on the principles of inkjet printers, eject tiny droplets of material from a nozzle, solidifying layer by layer along a defined path. Currently, the resins used in 3D sand printers both domestically and internationally have been plagued by issues such as poor performance, printhead corrosion, and clogging. These issues directly impact various technical parameters of the sand molds, severely limiting the quality control of castings. To meet the high-efficiency, energy-saving, and environmentally friendly "green casting" philosophy, it is necessary to develop a furan resin sand blend with performance suitable for 3D printers. Even if the technical issues surrounding the furan resin sand blend ratio are resolved, the raw material preparation equipment will need to be updated to precisely deliver the raw material according to the designed dosage.

[0003] At present, when furan resin is mixed, a reactor is used to stir and mix the mixture. Although the existing reactor also has a heating function during stirring and mixing, in actual use, the heating temperature often exceeds the preset temperature. The temperature can only be adjusted upward in time. When the temperature is lowered, the reactor often adopts a static cooling method, which seriously affects the work efficiency. Therefore, a furan resin heating and temperature control device is proposed to address the above problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] See also Figure 1 、 Figure 2 and Figure 3 , the utility model provides a technical solution:

[0032] A furan resin heating and temperature control device comprises an insulation box 1 and a stirring box 2.

[0033] The stirring box 2 is arranged inside the heat preservation box 1. The top of the stirring box 2 is fixedly connected to a stirring motor 3. The end of the main shaft of the stirring motor 3 is fixedly connected to a stirring shaft 4. The outer side of the stirring shaft 4 is fixedly connected to a stirring frame 5.

[0035] The internal heating mechanism 7 includes a heating plate 701 , a connecting rod 702 and a heater 703 . The bottom of the heating plate 701 is fixedly connected to the connecting rod 702 , and the bottom of the connecting rod 702 is fixedly connected to the mixing box 2 . The heater 703 is installed inside the heating plate 701 .

[0036] There are two stirring racks 5 , and stirring rods 6 are evenly distributed and fixedly connected to the outer sides of the stirring racks 5 .

[0037] A spiral tube 9 is also installed inside the above-mentioned insulation box 1, and one end of the spiral tube 9 is connected to a second circulation pump 10, the other end of the above-mentioned second circulation pump 10 is connected to a heating tube 11, and the other end of the above-mentioned heating tube 11 is connected to the spiral tube 9.

[0038] A heating rod 12 for heating the interior of the heating tube 11 is installed inside the heating tube 11 .

[0039] At present, when furan resin is mixed, a reactor is used to stir and mix it. Although the existing reactor also has a heating function when stirring and mixing, in actual use, the heating temperature often exceeds the preset temperature, and the temperature can only be adjusted up in time. When the temperature is lowered, it is often left to cool, which seriously affects the working efficiency. The present device is connected to an external power supply when in use, and an internal heating mechanism 7 and a cooling mechanism 8 are provided inside the mixing box 2. The water inside the heating plate 701 is heated by the heater 703 inside the heating plate 701, thereby facilitating the heating of the material. The spiral tube 9 is used to heat the outer wall of the mixing box 2. At this time, the internal and external materials can be heated together, which greatly improves the heating efficiency of the material. Once the heating temperature is too high, the cooling mechanism 8 can be started to achieve rapid cooling to ensure that the material is in an appropriate range.

[0040] In this embodiment, the stirring motor 3 drives the stirring shaft 4 to rotate, and the stirring shaft 4 drives the stirring frame 5 to rotate to fully stir the material, and a stirring rod 6 is provided on one side of the stirring frame 5, which can further ensure the stirring quality, and the second circulation pump 10 is provided to drive the water to flow. When the water passes through the heating cylinder 11, the heating rod 12 inside it heats the water, and then enters the spiral tube 9. At this time, the material inside the mixing box 2 can be heated, and in conjunction with the internal heating mechanism 7, it can achieve heating of both the inside and the outside of the material to ensure heating efficiency.

[0041] Example 2

[0042] This embodiment is an improvement on embodiment 1. Figure 4 and Figure 5Specifically, the cooling mechanism 8 includes a first circulation pump 801, a cooling pipe 802 and a cooling frame 803. The bottom of the first circulation pump 801 is fixedly connected to the mixing box 2. The output end and the input end of the first circulation pump 801 are both connected with the cooling pipe 802. The other end of the cooling pipe 802 at the output end is connected with the cooling frame 803. Multiple groups of baffles 804 and a group of transverse plates 805 are installed inside the cooling frame 803. The top of the cooling frame 803 is connected with a return pipe 806, and the other end of the return pipe 806 is connected with a water tank 807. A heat exchanger 808 is installed on the top of the water tank 807, and the output end of the heat exchanger 808 is connected with the cooling pipe 802 at the input end of the first circulation pump 801.

[0043] The top of the cooling frame 803 is also fixedly connected to a connecting column 809 , and the top of the connecting column 809 is fixedly connected to the mixing box 2 , and the interior of the connecting column 809 is fixedly connected to the cooling pipe 802 and the reflux pipe 806 .

[0044] The baffles 804 are all arranged vertically.

[0045] The transverse plate 805 is arranged in a transverse direction, and through holes are provided on both sides of the transverse plate 805 .

[0046] The input end of the heat exchanger 808 extends into the water tank 807 .

[0047] During the cooling process, the first circulation pump 801 is started to drive the cold water in the water tank 807 into the cooling frame 803, and then the water circulates through the labyrinth baffle 804 to ensure the cooling efficiency. The heat exchanger 808 is set to ensure that the return water is cooled, ensuring the cooling quality of the material by the baffle 804.

[0048] In this embodiment, when cooling the material whose temperature exceeds the preset temperature, the first circulation pump 801 is started. At this time, cold water enters the cooling frame 803 through the cooling pipe 802, and can fully and effectively cool the cooling frame 803 through the maze-like baffle 804, and is discharged through the through hole on one side of the transverse plate 805, and then enters the water tank 807 through the return pipe 806. When the water circulates, the heat exchanger 808 provided therein can cool the water to ensure the subsequent cooling quality. This setting can actively cool the material, shorten the cooling time, and effectively ensure that the material can be used quickly.
