Description
Technical Field
[0001] This utility model relates to the technical field of integrated dehumidification, drying and conveying machines, and in particular to an integrated PC plastic dehumidification, drying and conveying machine. Background Technology
[0002] With the rapid development of the plastics processing industry, especially the increasing requirements for raw material processing in fields such as injection molding, blow molding, and film production, PC plastic, as a high-performance and high-transparency material, is being used more and more widely.
[0003] Existing integrated PC plastic dehumidification, drying, and conveying machines still have some shortcomings in actual use:
[0004] 1. During the dehumidification and drying process of PC plastic, the main method is to agitate the PC plastic using stirring blades to increase the gaps between the PC plastic particles and thus facilitate drying. However, this agitation method does not effectively agitate the PC plastic at the bottom of the mixing tank, resulting in insufficient agitation.
[0005] 2. Existing PC plastic drying equipment mainly relies on opening valves after dehumidification and drying to allow the accumulated PC plastic to flow out automatically along the conveying pipe. Some PC plastic accumulates inside the dehumidification and drying drum, which is not convenient to clean and also cannot be conveyed to the next process. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies where the tumbling method fails to effectively tumble the PC plastic at the bottom of the mixing tank, resulting in insufficient tumbling, accumulation of PC plastic in the dehumidification and drying tank, inconvenient cleaning, and inability to convey the PC plastic to the next process. Therefore, this invention proposes an integrated PC plastic dehumidification, drying, and conveying machine.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] An integrated PC plastic dehumidification, drying, and conveying machine includes a base, a turning bucket fixedly installed on the top of the base, a conveying frame fixedly installed on the top of the base, and the turning bucket and the conveying frame are connected. A valve is fixedly installed at one end of the conveying frame. A stirring shaft is rotatably connected inside the turning bucket and extends above the turning bucket. A conical plate is fixedly fitted on the outer wall of the stirring shaft, and multiple stirring blades are fixedly fitted on the outer wall of the stirring shaft. The stirring blades can turn the PC plastic.
[0009] In one possible design, an auger is fixedly and rotatably connected inside the conveyor frame, with one end of the auger extending to the outside of the conveyor frame. A second drive motor is fixedly installed on the top of the base, with one end of the output shaft of the second drive motor fixedly connected to one end of the auger. A discharge pipe is fixedly installed on the bottom of the conveyor frame, and the discharge pipe is connected to the interior of the conveyor frame.
[0010] In one possible design, multiple pushing blocks are fixedly connected to the top of the conical plate. The top of the conical plate is conical. There is a gap between the tipping bucket and the conical plate. Water slides down the top of the conical plate to the bottom of the conical plate. A first drive motor is fixedly installed on the top of the tipping bucket. Gears are fixedly sleeved on the outer walls of the output shaft and the stirring shaft of the first drive motor, and the two gears mesh with each other.
[0011] In one possible design, a molecular sieve dehumidification tower is fixedly installed on the top of the base, and a heater is provided above the molecular sieve dehumidification tower. The molecular sieve dehumidification tower and the heater and the heater and the stirring shaft are all connected by conveying pipes, and one end of one of the conveying pipes is rotatably engaged with the top end of the stirring shaft. The stirring shaft is hollow, and an air vent is provided inside the stirring blade, and the air vent is connected to the hollow part inside the stirring shaft.
[0012] In one possible design, a circulating pump is fixedly installed on the top of the base, and the molecular sieve dehumidification tower and the circulating pump, as well as the turning bucket and the circulating pump, are connected by circulating pipes.
[0013] In one possible design, the top of the tipping hopper is provided with a loading pipe, and one side of the tipping hopper is provided with a liquid outlet pipe, which is located below the conical plate.
[0014] In this application, PC plastic is loaded into the tilting hopper through the inlet. The first drive motor is started, and its output shaft drives two meshing gears to rotate. One gear drives the stirring shaft to rotate, which in turn drives multiple stirring blades. The stirring shaft then drives a conical plate to rotate. Multiple pushing blocks are mounted on the top of the conical plate. As the conical plate rotates, the pushing blocks push the material from the bottom. When the PC plastic is tilted, water on the surface of the PC plastic can slide down the top of the conical plate, passing between the conical plate and the inner wall of the tilting hopper, and falling below the tilting hopper and the conical plate. Simultaneously, the circulation system is activated when the stirring blades rotate. The pump is connected to the tipping hopper and the molecular sieve dehumidification tower via circulation pipes. The circulation pump draws humid air from the tipping hopper into the molecular sieve dehumidification tower for dehumidification, and then into the heater for drying. The dried air then enters the stirring shaft through a conveying pipe. The stirring shaft, connected to the air vents in the stirring blades, discharges hot air while simultaneously drying the PC plastic. After drying, the discharge valve on one side of the tipping hopper is opened, and the PC plastic slides down the discharge pipe into the conveyor frame. The second drive motor is then started, and its output shaft drives the auger to rotate, conveying the material to the discharge pipe for the next process.
[0015] Beneficial effects: In this utility model, the integrated PC plastic dehumidification, drying and conveying machine, through the turning mechanism and dehumidification and drying system composed of a stirring shaft, stirring blades, conical plate and pushing block, can ensure that the PC plastic is fully turned over during the drying process, thereby increasing its contact area with hot air and improving dehumidification and drying efficiency;
[0016] In this utility model, the all-in-one machine integrates three major functions: dehumidification, drying and conveying. Driven by the first drive motor and the second drive motor, it realizes automated operation. Users only need to load PC plastic into the turning bucket through the loading pipe to automatically complete the entire process of dehumidification, drying and conveying, which greatly saves manpower and time costs.
[0017] The integrated PC plastic dehumidification, drying and conveying machine of this invention has the advantages of high efficiency in dehumidification and drying, high degree of automation, compact structure, energy saving and environmental protection, as well as simple operation and convenient maintenance.
