Description
Technical Field
[0001] The present application relates to the technical field of masterbatch recovery, and in particular to a drying device for a masterbatch recovery machine. Background Art
[0002] When recycling masterbatch waste, it needs to be melted, extruded, and peeled. Since the temperature after peeling is high, it needs to be cooled. In the prior art, water cooling is usually used to cool it down and shape it. Therefore, after pelletizing, it is necessary to dry it. Usually, a drying device is used, which is a key equipment to ensure the quality of recycled masterbatch.
[0003] At present, there are many drying devices on the market, which mainly remove moisture and impurities from masterbatches by heating and ventilation. Common masterbatch drying devices use electric heating wires for heating and fans for ventilation to achieve masterbatch drying. However, during the drying process, due to the limitations of electric heating wires, the masterbatch is often heated unevenly, affecting the drying effect. In addition, since part of the electric heating wire will be converted into electromagnetic radiation during the heating process, the heating efficiency of the masterbatch is reduced, which in turn increases a certain production cost, so further improvement is needed. Utility Model Content
[0004] In order to improve the drying effect of masterbatch while reducing energy consumption, the present application provides a drying device for a masterbatch recovery machine.
[0005] The present application provides a drying device for a masterbatch recovery machine, which adopts the following technical solution:
[0006] A drying device for a masterbatch recovery machine comprises a frame, a heating tank arranged on the frame, and an electromagnetic heating channel fixedly arranged through the heating tank for conveying masterbatch to the heating tank, a stirring assembly for stirring masterbatch is arranged in the heating tank, and a discharge pipe is arranged at the bottom of the heating tank.
[0007] By adopting the above technical solution, an electromagnetic heating channel is provided, and before the masterbatch enters the heating tank for heating, it is first preheated during the transportation process to the heating tank through the electromagnetic heating channel, so as to reduce the time spent in the transportation process of heating in the heating tank, as well as the heating time and difficulty required in the heating tank, thereby accelerating the heating and drying efficiency of the masterbatch, and cooperating with the stirring component to heat and stir the masterbatch in the heating tank, so that the masterbatch is heated relatively evenly, so as to improve its drying efficiency. And because electromagnetic heating is a physical phenomenon that uses high-frequency electromagnetic fields to generate eddy currents and self-excited heat, its heating efficiency is higher than that of electric heating wires, and is relatively energy-saving compared to electric heating wires, which can reduce energy consumption while improving the drying efficiency of the masterbatch.
[0008] Preferably, a plurality of partition plates are arranged at intervals along the height direction of the heating tank, and the plurality of partition plates are used to divide the inner cavity of the heating tank into a plurality of drying zones. Through grooves are penetrated through the upper surfaces of the partition plates, and the through grooves on adjacent partition plates are staggered. The electromagnetic heating channel is located above the uppermost partition plate.
[0009] By adopting the above technical solution, the inner cavity of the heating tank is divided into several drying zones by setting several partition plates. The heating tank first heats the masterbatch that has just entered the heating tank along the electromagnetic heating channel, and with the stirring of the stirring component, the heat exchange effect between the masterbatch and the hot air in the heating tank is improved. With the stirring of the stirring component, a part of the masterbatch is stirred to the through groove to fall into the next drying zone for heating, so as to heat in different zones in the heating tank, reduce the possibility of uneven heating caused by accumulation heating, and increase the contact area between the masterbatch and the hot air, thereby further improving the drying effect and efficiency of the masterbatch.
[0010] Preferably, the partition plate is inclined in a direction away from the through groove, and the stirring assembly includes an abutment plate connected to the partition plate and a driving member driving the abutment plate to rotate around the axis of the heating tank, and the abutment plate is elastic.
[0011] By adopting the above technical solution, the partition plate is tilted away from the through groove, so that the master particles falling onto the partition plate roll down along the tilt direction of the partition plate, and the master particles falling through the through groove to the next layer of the partition plate are reduced. Instead, the master particles fall directly through the through groove, so as to further increase the retention time of the master particles in the drying area, thereby improving the drying effect of the master particles and reducing the drying efficiency and energy consumption affected by repeated drying.
[0012] Preferably, an opening and closing component for opening and closing the through slot is provided on the partition plate.
[0013] By adopting the above technical solution and providing an opening and closing component to open and close the through slot, the retention time of the masterbatch in the drying zone can be increased, and the possibility of discharge from the discharge pipe due to insufficient drying can be reduced.
[0014] Preferably, the opening and closing assembly includes a cover plate covering the through groove and an elastic member pushing the cover plate to cover the through groove, the cover plate is arranged on the lower surface of the partition plate, the upper surface of the cover plate and the lower surface of the partition plate are directly inclined, and when the cover plate covers the through groove, the end of the cover plate away from the elastic member is a protrusion protruding from the upper surface of the partition plate; the stirring assembly includes a rotating rod passing through a plurality of partition plates, a stirring rod arranged on the rotating rod and built into the drying zone, and a driving member driving the rotating rod to rotate, and the stirring rod is protruded with an abutting portion for abutting against the protrusion.
[0015] By adopting the above technical solution, with the elasticity of the elastic member itself, the cover plate is driven to cover the through slot. When the stirring rod stirs to the cover plate position, due to the abutment between the abutment part and the protrusion part, the cover plate is pushed to move toward the elastic member to open the through slot, so that the masterbatch falls into the drying area below to continue heating and drying. Since the upper surface of the cover plate and the lower surface of the partition plate are arranged at an angle, when the protrusion part gradually moves toward the cover plate, its height position changes, so that the abutment part slides away from the protrusion part, and at this time, under the influence of the elastic force of the elastic member, the cover plate is pushed to cover the through slot to close the through slot.
[0016] Preferably, the partition plate is located on an inner side wall of the through groove and is provided with a second sliding groove for the cover plate to be slidably connected thereto, and the elastic member is a second spring, and the second spring is built into the second sliding groove.
[0017] By adopting the above technical solution, the sliding path of the cover plate is limited by the second sliding groove.
[0018] Preferably, the outer peripheral wall of the heating tank is provided with an air pipe for introducing hot air to heat the masterbatch.
[0019] By adopting the above technical solution, hot air is introduced to heat the masterbatch, and the masterbatch is heated as it falls through the groove onto the partition plate below.
[0020] Preferably, the outer peripheral wall of the heating tank and the outer peripheral wall of the electromagnetic heating channel are both covered with heat insulation cotton.
[0021] By adopting the above technical solution, the possibility of burns caused by accidentally touching the outer wall of the heating tank and the outer wall of the electromagnetic heating channel is reduced.
[0022] In summary, the utility model has the following beneficial effects:
[0023] By providing an electromagnetic heating channel, the masterbatch is preheated during the transportation to the heating tank before entering the heating tank for heating, so as to reduce the time spent in the transportation process of heating in the heating tank, as well as the heating time and difficulty required in the heating tank, thereby accelerating the heating and drying efficiency of the masterbatch, and cooperating with the stirring component to heat and stir the masterbatch in the heating tank, so that the masterbatch is heated relatively evenly to improve its drying efficiency. And because electromagnetic heating is a physical phenomenon that uses high-frequency electromagnetic fields to generate eddy currents and self-excited heat, its heating efficiency is higher than that of electric heating wires, and is relatively energy-saving compared to electric heating wires. It can reduce energy consumption while improving the drying efficiency of the masterbatch. BRIEF DESCRIPTION OF THE DRAWINGS
