Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a drying and material extraction device. Background Technology

[0002] In the production of plastic products, extruders are typically used to melt and extrude plastic granules for use in molding equipment. Before being used in production, the plastic granules need to be dried in a silo for a certain period of time to remove moisture and prevent air bubbles from forming in the plasticized material, which would affect the quality of the plastic products. However, in actual production, due to uncertainties on both the supply and demand sides, the supply of plastic granules and the production of plastic products are subject to unforeseen circumstances such as temporary arrangements. This often results in the plastic granules being dried only when production is needed, and the drying time is generally no less than 60 minutes, severely impacting the production efficiency of plastic products. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a drying and feeding device that can provide rapid drying and storage functions for plastic granules, shorten the waiting time for plastic product production, and improve production efficiency.

[0019] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] like Figure 1-3As shown, a drying and material extraction device includes a trolley, a drying chamber, heating plates, and a self-priming pump. The drying chamber is fixedly connected to the trolley and has a storage cavity inside. An inlet pipe communicating with the storage cavity is located at the upper end of the drying chamber, and an outlet pipe communicating with the storage cavity is located at the lower end. The self-priming pump is fixedly connected to the upper end of the drying chamber, and its output end connects to the inlet pipe. Multiple heating plates are installed at an angle inside the storage cavity, and these plates alternately abut against the inner walls of the drying chamber on both sides of the storage cavity, forming a reciprocating downward channel. The portability of the trolley allows the device to be moved to locations where material extraction and drying are required. Next to the extruder, a self-priming pump pumps the plastic granules from the raw material ton bag and sends them to the drying chamber. Under the action of gravity, the plastic granules roll and are heated on the inclined electric heating plate, and are discharged from the discharge pipe through the reciprocating downward channel. The discharge pipe is connected to the extruder's suction pump through a pipeline, which sucks the quickly dried plastic granules into the extruder's hopper. During this process, the heating plate heats up to 80-100℃, which is slightly higher than the drying temperature of the extruder's hopper. This temperature is conducive to the rapid heating and drying of the plastic granules, and also avoids the damage to the physical and chemical properties of the plastic caused by excessively high temperatures, which would reduce the strength and toughness of the plastic.

[0021] In the above embodiment, a frame is provided on one side of the storage chamber, and an L-shaped groove is provided on the outer side of the frame. One end of the heating plate abuts against the L-shaped groove, and the other end leans against the other side of the storage chamber. There are multiple frames, which are alternately distributed from top to bottom on the inner walls of the drying chamber on both sides of the storage chamber. The frame provides a support point for the heating plate and a descent channel for the plastic particles, ensuring that the plastic particles roll backward after hitting the wall. A support plate is provided between the outer side of the frame and the side of the storage chamber to provide a support point for the heating plate and prevent the heating plate from bending and deforming under the weight and impact of the plastic particles, thus preventing damage. An inclined guide plate is provided at the bottom of the storage chamber. The guide plate is inclined and guides the discharge pipe to prevent the plastic particles from accumulating at the bottom of the storage chamber. A vibrator is provided at the lower end of the guide plate to prevent the plastic particles from forming a blockage in the storage chamber.

[0022] The feed pipe has a feed inlet and a mesh air outlet at the same height on both sides. The output end of the self-priming pump is connected to the feed inlet. Since the plastic granules pumped from the ton bag may contain moisture, the pumped gas also contains some moisture. After the pumped gas carries the plastic granules into the feed pipe, the gas is discharged from the mesh air outlet, while the plastic granules are intercepted and fall into the storage chamber for drying. At the same time, the mesh air outlet also provides a heat dissipation channel for the storage chamber, preventing the storage chamber temperature from becoming too high and damaging the physical and chemical properties of the plastic. The trolley has handles on both sides, making it easy for operators to adjust the position by pushing and pulling it from both sides. The front of the drying chamber has a door, which facilitates cleaning of the storage chamber and maintenance and replacement of the heating plates. The door is made of transparent material, allowing real-time observation of the storage chamber and timely detection and handling of blockages.

[0023] Description of the working principle of this utility model:

[0024] When the plastic in ton bags needs to be dried quickly and produced, push this device next to the hopper of the plastic extruder, insert the suction pipe connected to the input end of the self-priming pump into the ton bag, and connect the discharge pipe of this device to the suction pump of the extruder through a pipeline. After the heating plate is powered on for about 5 minutes, it reaches its rated temperature of 80℃ and continues to heat for another 5 minutes to eliminate moisture in the storage chamber and its connected pipes, while simultaneously creating an ambient temperature of 40-50℃ within the storage chamber. After starting the self-priming pump, plastic granules enter the feed pipe from the ton bag. Under the separation action of the feed pipe, gas is discharged from the mesh air outlet, while the plastic granules fall into the storage chamber. Once inside the storage chamber, the plastic granules fall onto the heating plate and roll down along it under gravity, absorbing heat from the heating plate and the storage chamber during this process, thus achieving rapid drying. After multiple layers of repetitive rolling descent, the plastic granules accumulate in the storage chamber at the top of the discharge pipe and, under the action of the extruder's suction pump, enter its hopper, ready for rapid production.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
