DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0027] The following is combined with Figure 1-4 The embodiments of the present application are described in further detail.
[0028] Example 1
[0029] See also Figure 1-Figure 4 , the utility model provides a technical solution: a plastic recycling hot washing pot, comprising: a processing pot body 1, a feed pipe 2, a liquid inlet pipe 3, a discharge pipe 4 and an auxiliary conveying mechanism 6;
[0030] The processing pot body 1 is composed of a pot body and a pot cover on the top, which can be easily opened later to clean the internal structure of the processing pot body 1. The feed pipe 2 is welded on one side above the processing pot body 1, and the feed pipe 2 can transport plastic to the inside of the processing pot body 1. The liquid inlet pipe 3 is welded on the other side above the processing pot body 1, and the liquid inlet pipe 3 can provide a cleaning agent to be transported to the inside of the processing pot body 1 so as to be mixed with the plastic. The discharge pipe 4 is welded on the bottom of the processing pot body 1, and the discharge pipe 4 can discharge the cleaned plastic to the outside of the processing pot body 1.
[0031] The auxiliary conveying mechanism 6 is arranged below the heating and stirring mechanism 5. When the plastic is subsequently conveyed through the discharge pipe 4, the auxiliary conveying mechanism 6 can drive the plastic to move to the inside of the discharge pipe 4 for discharge. The auxiliary conveying mechanism 6 includes a fixed plate 601 arranged below the heating and stirring mechanism 5. The fixed plate 601 can be rotated by the heating and stirring mechanism 5 to rotate synchronously. A vertical hole is opened on the fixed plate 601, which can provide the internal structure with stable vertical displacement. The limiting frame 602 welded below the fixed plate 601 can provide the internal structure with vertical displacement, and the cross-section of the limiting frame 602 is in the shape of a "mouth", which can effectively limit the internal structure around.
[0032] The movable block 603 is vertically slidably connected to the inner part of the limit frame 602, and the movable block 603 can stably move in the vertical direction inside the limit frame 602. The scraper 604 welded to the bottom of the movable block 603 can be synchronously displaced by connecting with the movable block 603, so that the bottom end of the scraper 604 fits on the inner bottom of the processing pot body 1, and the bottom of the scraper 604 is arranged above the inner bottom of the processing pot body 1. The scraper 604 can be rotated by the fixed plate 601. During the processing, it rotates synchronously, thereby driving the plastic at the bottom of the pot body 1 to move and transport. The guide rod 605 welded on the top of the movable block 603 is set in the vertical hole of the fixed plate 601. The guide rod 605 can stably displace in the vertical hole of the fixed plate 601, thereby driving the movable block 603 connected below to move synchronously and stably, and the diameter of the guide rod 605 is adapted to the diameter of the vertical hole of the fixed plate 601, so that it can be more stable during the vertical movement.
[0033] The spring 606 sleeved on the guide rod 605 can perform extrusion work in the vertical direction, and the two ends of the spring 606 are respectively arranged on the outer walls of the fixed plate 601 and the movable block 603, so that when the spring 606 realizes extrusion and pushes the movable block 603 to move in the vertical direction, it can be more stable. The screw 607 welded on the top of the guide rod 605 can provide the structure on the rod to rotate stably so as to move, and the diameter of the screw 607 is smaller than the diameter of the guide rod 605, so that the structure on the screw 607 can be stably placed above the guide rod 605. The annular baffle 608 sleeved on the screw 607 can prevent the guide rod 605 from deviating when it moves in the vertical hole of the fixed plate 601. The nut 609 connected to the screw 607 is rotatably arranged above the annular baffle 608, and the nut 609 is arranged above the annular baffle 608. The nut 609 can provide the annular baffle 608 to be stably fixed on the screw 607.
[0034] The plastic can be quickly transported to the interior of the processing pot body 1 through the feed pipe 2, and the cleaning liquid can be transported to the interior of the processing pot body 1 through the liquid inlet pipe 3. When the cleaned plastic needs to be transported to the discharge pipe 4 later, the rotation of the fixed plate 601 can drive the scraper 604 at the bottom of the movable block 603 in the lower limit frame 602 to rotate synchronously, and the movable block 603 is squeezed in the vertical direction by the spring 606 on the guide rod 605. At this time, the bottom of the scraper 604 can be attached to the bottom of the processing pot body 1. At this time, during the rotation of the scraper 604, the plastic at the bottom of the processing pot body 1 can be driven to move to the inside of the discharge pipe 4 for transportation. When the scraper 604 needs to be disassembled and cleaned later, the nut 609 is rotated and removed from the screw 607 at the top of the guide rod 605. At this time, the annular baffle 608 can be removed from the screw 607, so as to facilitate the sliding and disassembly of the guide rod 605 from the inside of the fixed plate 601.
[0035] Example 2
[0036] See also Figure 1-Figure 4 , the utility model provides a technical solution: a plastic recycling hot washing pot, comprising: a heating and stirring mechanism 5;
[0037] The heating and stirring mechanism 5 is arranged inside the processing pot body 1. The heating and stirring mechanism 5 can stir, mix and clean the cleaning liquid and plastic inside the processing pot body 1. The heating and stirring mechanism 5 includes a driving motor 501 fixedly arranged below the processing pot body 1. The driving motor 501 can drive the structure connected to the output end to rotate stably. The stirring blade 502 is fixedly arranged on the output end of the driving motor 501. The stirring blade 502 is engaged with the driving motor 501 and can rotate stably, thereby stirring and mixing the cleaning liquid and the plastic. During the rotation process, the stirring blade 502 can synchronously drive the fixing plate 601 connected by the bolts below to rotate synchronously. The electric heating wire 503 is fixedly arranged on the top of the processing pot body 1. The electric heating wire 503 can provide heating for the cleaning liquid, thereby improving the cleaning efficiency.
[0038] Starting the electric heating wire 503 can drive the cleaning liquid in the processing pot body 1 to heat up, and starting the driving motor 501 can drive the stirring blade 502 on the output end to rotate when the driving motor 501 is working, so as to stir and mix the cleaning liquid and the plastic, thereby improving the cleaning efficiency of the plastic.
[0039] The implementation principle of a plastic recycling hot washing pot in this application is:
[0040] First, start the electric heating wire 503 to heat up the cleaning liquid in the processing pot body 1, and start the driving motor 501. When the driving motor 501 is working, it can drive the stirring blade 502 on the output end to rotate, thereby stirring and mixing the cleaning liquid and the plastic, thereby improving the cleaning efficiency of the plastic.
[0041] Secondly, the plastic can be quickly transported to the interior of the processing pot body 1 through the feed pipe 2, and the cleaning liquid can be transported to the interior of the processing pot body 1 through the liquid inlet pipe 3. When the cleaned plastic needs to be transported to the discharge pipe 4 later, the rotation of the fixed plate 601 can drive the scraper 604 at the bottom of the movable block 603 in the lower limit frame 602 to rotate synchronously, and the movable block 603 is squeezed vertically by the spring 606 on the guide rod 605. At this time, the bottom of the scraper 604 can be attached to the bottom of the processing pot body 1. At this time, during the rotation of the scraper 604, the plastic at the bottom of the processing pot body 1 can be driven to move to the inside of the discharge pipe 4 for transportation.
[0042] Finally, when the scraper 604 needs to be disassembled and cleaned later, the nut 609 is rotated and removed from the screw 607 at the top of the guide rod 605. At this time, the annular baffle 608 can be removed from the screw 607, thereby facilitating the guide rod 605 to be slid and disassembled from the inside of the fixed plate 601.
