[0001] The utility model relates to the technical field of drying machines, in particular to a plastic rice drying machine which is convenient for temperature control. Background Art
[0002] Plastic rice is the common name for plastic raw materials. Most of the plastic raw materials are made into granules. The plastic rice just squeezed out by the injection molding machine carries a small amount of moisture, which will affect the production of subsequent production processes. Therefore, it is necessary to use a plastic dryer to dry the plastic rice. A plastic dryer is a machine that can remove moisture from plastic particles.
[0003] The common plastic dryer now includes a barrel, a fan, a heating tube and a controller. The plastic rice to be dried is poured into the barrel, and the fan and the heating tube are turned on by the controller. The wind generated by the fan enters the barrel after being heated by the heating tube to dry the plastic rice in the barrel.
[0004] For the above technical conditions, there is still a defect that the insulation effect of the heating tube is not good enough, and the hot air loses some heat at the heating tube, resulting in a temperature difference between the hot air acting on the barrel and the hot air at the heating tube, making it difficult for the controller to accurately control the temperature.
[0005] Based on this, the utility model designs a plastic rice drying machine which is easy to control temperature to solve the above problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The following is combined with Figure 1-5 This application is described in further detail.
[0024] A plastic rice drying machine which is easy to control temperature comprises a barrel 5, a fan 1, a heating tube 6 and a controller 2. The heating tube 6 is fixedly connected to the barrel 5, the fan 1 is fixedly connected to the heating tube 6, the fan 1 is fixedly provided with a fixing frame 9, and the controller 2 is fixedly connected to the fixing frame 9.
[0025] The controller 2 is electrically connected to the fan 1, and the heating tube 6 is electrically connected to the controller 2. A heating wire is provided on the heating tube 6. The fan 1 and the heating tube 6 are turned on by the controller 2, and the fan 1 blows air to the heating tube 6. The heating wire on the heating tube 6 heats the air, and the heated air flows to the barrel 5 to dry the plastic rice in the barrel 5.
[0026] The heating tube 6 is sleeved with an insulation tube 3, and the insulation tube 3 is fixedly provided with a mounting plate 10. The mounting plate 10 and the insulation tube 3 are integrally formed. Two mounting plates 10 are provided on the insulation tube 3, and the two mounting plates 10 are respectively provided on both sides of the insulation tube 3. A mounting hole is opened on the mounting plate 10, and the mounting hole is sleeved on the heating tube 6, and the inner wall of the mounting hole is pressed against the outer wall of the heating tube 6.
[0027] An insulation layer 8 is sleeved on the heating tube 6, and both ends of the insulation layer 8 are fixedly connected to the mounting plate 10, and the insulation layer 8 is between the heating tube 6 and the thermal insulation tube 3. An isolation tube 7 is fixedly arranged on the insulation layer 8, and both ends of the isolation tube 7 are fixedly connected to the mounting plate 10. The isolation tube 7 and the mounting plate 10 are integrally formed, and the isolation tube 7 is between the insulation layer 8 and the thermal insulation tube 3.
[0028] The heat insulating layer 8 is made of heat insulating cotton, which has a good heat insulating effect and can well insulate the heating tube 6. There is a hollow structure between the isolation layer and the heat insulating tube 3, and there is a vacuum state between the isolation layer and the heat insulating tube 3. The heat conduction efficiency is poor in the vacuum state, so that the heat of the heating tube 6 is not easy to lose.
[0029] The outer wall of the insulation pipe 3 is fixedly provided with an insulation layer, which is made of a material with good insulation effect, and strengthens the insulation effect of the insulation pipe 3 on the heating pipe 6. The insulation pipe 3 is sleeved with a heat insulation sleeve 4, which is sleeved on the barrel 5. The heat insulation sleeve 4 insulates the connection between the barrel 5 and the heating pipe 6, and reduces the heat loss between the heating pipe 6 and the barrel 5.
[0030] The implementation principle of this embodiment is as follows: the fan 1 and the heating tube 6 are turned on by the controller 2, the fan 1 blows air to the heating tube 6, the heating tube 6 heats the air, and the heated hot air is directed to the barrel 5 to dry the plastic rice in the barrel 5. When the heating tube 6 is being heated, the heat insulation layer 8 made of heat preservation cotton performs the first layer of heat preservation on the heating tube 6; the vacuum state between the isolation tube 7 and the insulation tube 3 has the characteristic of poor heat conduction, so the heating tube 6 can be insulated in the second layer, and finally the insulation tube 3 and the insulation layer perform the third layer of heat preservation on the heating tube 6. At this time, under the action of the three-layer insulation measures, the heat loss of the heating tube 6 is small, and the temperature of the hot air flowing from the heating tube 6 to the barrel 5 is basically the same as the temperature in the heating tube 6, so that the temperature difference between the hot air acting on the barrel 5 and the hot air at the heating tube 6 is small, which is convenient for the controller 2 to control the temperature and achieve the effect of strengthening the heat preservation effect of the heating tube 6.
