[0014] Below, in conjunction with the accompanying drawings and [specific implementations], the utility model is further described:
[0015] As shown in FIG. 1, it is a schematic structural diagram of a plastic raw material dryer according to a preferred embodiment of the present invention, including a hopper 1, and a hopper cover 2 is detachably installed on the opening of the hopper 1, on the hopper cover 2. The exhaust elbow 3 is connected with the air return pipe 4, the other end of the air return pipe 4 is connected to the hopper 1, and the air return pipe 4 is also connected with a vent pipe, and the other end of the vent pipe is arranged There is a moisture adsorption layer; the blower 5 is connected to the hot air pipe 6, a heater 7 is provided in the hot air pipe 6, and the hot air pipe 6 is connected to the hopper 1. A temperature sensor 8 is installed in the hopper 1 to sense the temperature The device 8 is signally connected to the controller 9, and the controller 9 is signally connected to the heater 7 and the blower 5 respectively.
[0016] Since the hot air discharged from the exhaust elbow 3 can return to the hopper 1 through the air return pipe 4, the thermal energy in the hot air can be used, and the dust particles in the hot air can be returned to the hopper 1 again. Thereby, the impact on the workshop environment and the waste of materials can be reduced; at the same time, because the air return pipe 4 is also connected with a vent pipe 14, the other end of the vent pipe 14 is provided with a moisture adsorption layer 15, and the return air pipe can be removed through the moisture adsorption layer 15. The moisture adsorption in 4 can ensure the drying effect by regularly replacing the moisture adsorption layer 15; in addition, in order to avoid the temperature and air pressure in the hopper 1 from being too high, affecting the drying quality of the plastic raw materials, a temperature is also installed in the hopper 1. The sensor 8, when the temperature in the hopper 1 is higher than the temperature set by the controller 9, the controller 9 controls the heater 7 to stop operating, on the contrary, when the temperature in the hopper 1 is lower than the temperature set by the controller 9 When the value is reached, the controller 9 controls the operation of the heater 7; in this way, not only the drying quality of the plastic raw materials can be ensured, but also the power consumption can be reduced. Of course, it should be noted that after understanding the working principle of the present invention, those skilled in the art can inevitably select the corresponding controller 9 and the corresponding control program, which will not be described in detail here.
[0017] At the same time, in order to ensure the discharge efficiency of the plastic raw materials and avoid the plastic raw materials from being blocked in the discharge port 10 of the hopper 1, a vibrating hammer 11 is installed on the outer wall of the discharge port 10 of the hopper 1. The air pipe 12 is connected to an air pump (not shown); when the hopper 1 is discharging, the air pump can be activated to drive the vibrating hammer 11 to vibrate, which can effectively solve the technology of plastic material clogging at the discharge port problem.
[0018] Among them, in order to facilitate the observation of the amount of plastic raw materials in the hopper 1, an observation window 13 is opened on the hopper.
[0019] In addition, since the temperature in the hopper 1 is relatively high, in order to extend the service life of the hopper 1, a heat-resistant layer is also provided on the inner wall of the dry hopper 1. The heat-resistant layer can be made of silicone high-temperature resistant paint or Inorganic high temperature resistant coatings, etc.
[0020] Among them, the above-mentioned moisture adsorption layer 15 is soda lime, of course, other dry materials such as gelatin can also be used.
