Technical Field
[0001] This utility model relates to the field of plastic granule processing technology, specifically to an integrated drying and dehumidification device for plastic granules. Background Technology
[0002] Plastic granules refer to granular plastics, which are obtained by crushing plastic products with a crusher. The resulting plastic granules are washed with water. To avoid the wet plastic granules affecting subsequent processing, the washed plastic granules are dried using drying equipment.
[0003] Chinese patent CN219988160U discloses a plastic granule drying device, including a base plate and a material container. A fixing plate is fixedly connected to the top left end of the base plate, and a motor is fixedly installed on the outer side of the fixing plate. A connecting shaft is fixedly connected to the motor, and a drying cylinder is fixedly connected to the inner side of the fixing plate. This invention allows the motor to drive the connecting shaft to rotate, which in turn drives the material container to rotate through the cooperation of the insert rod and connecting column. The plastic granules inside the material container will then tumble. Simultaneously, a hot air blower is activated, delivering hot air through an air supply pipe and then through an air outlet pipe into the drying cylinder. The hot air then passes through the material container and enters the interior, drying the continuously tumbling plastic granules. This ensures that the hot air can evenly contact and dry the plastic granules, thereby accelerating the drying process, shortening the drying time, and improving drying efficiency.
[0004] However, the aforementioned plastic granule drying equipment cannot remove the moisture evaporated during the drying process from the drying chamber, which leads to a gradual increase in humidity in the drying environment, thus affecting drying efficiency. Furthermore, the accumulation of moisture hinders heat exchange between the hot air and the plastic granules, resulting in uneven heating and extending the drying time. Utility Model Content
[0005] The purpose of this invention is to provide an integrated drying and dehumidification equipment for plastic granules, in order to solve the problem mentioned in the background art that during the drying process of plastic granules, the moisture evaporated during drying cannot be removed from the drying chamber, which will hinder the heat exchange between the hot air and the plastic granules and lead to uneven heating effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An integrated drying and dehumidification device for plastic granules includes: two sets of connecting covers, a heat insulation cylinder fixedly installed between the two sets of connecting covers, a drying cylinder connected between the two sets of connecting covers, connecting cylinders fixedly installed on both sides of each connecting cover, a feeding mechanism rotatably installed inside each connecting cylinder, the feeding mechanism rotating in the upper half of the drying cylinder, and a dehumidification mechanism provided in the lower half of the drying cylinder.
[0008] Preferably, a fan is fixedly installed on the upper surface of the heat insulation cylinder, a guide cylinder is connected to the lower surface of the fan, an electric heating wire is fixedly installed inside the guide cylinder, and the other end of the guide cylinder is connected to the upper surface of the drying cylinder, so that the fan can guide hot air into the drying cylinder.
[0009] Preferably, ceramic fiber sheets are fixedly connected to both ends of the drying cylinder, so that the ceramic fiber sheets can contain the heat inside the drying cylinder.
[0010] Preferably, the feeding mechanism includes two sets of transmission columns, which are rotatably installed in the connecting cylinders of two sets of connecting covers, and two sets of conveyor belts are fitted on the outer surfaces of the two sets of transmission columns.
[0011] Preferably, a connecting column is fixedly installed between the two sets of conveyor belts, so that the connecting column can be driven by the conveyor belt in the upper part of the drying drum, and the spacing between each pair of connecting columns is sufficient to support the plastic granules.
[0012] Preferably, one set of the transmission columns is fixedly connected to the output shaft of the geared motor, and the geared motor is fixedly installed at one end of the heat insulation cylinder.
[0013] Preferably, the spacing between the connecting columns allows hot air to be blown over to evaporate the water vapor adhering to the surface of the plastic particles, and the continuous blowing of hot air allows the water vapor to come into contact with the dehumidification mechanism through the spacing between the connecting columns and condense into water droplets.
[0014] Preferably, the dehumidification mechanism includes a condenser, which is fixedly installed in the lower half of the drying cylinder, such that the condenser is located at the lower end of the connecting column.
[0015] Preferably, the lower half of the drying cylinder is connected to a liquid guide pipe, and the other end of the liquid guide pipe extends through to the outer surface of the heat insulation cylinder and is connected to a water tap.
[0016] Preferably, the condenser located at the lower end of the connecting column can cool the hot water vapor and condense it into water droplets, which then fall into the lower half of the drying cylinder and flow into the liquid guide pipe before being discharged to the outside through the faucet.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. Through the design of the drying drum, fan, guide tube, heating wire, dehumidification mechanism, and conveying mechanism, during the drying operation of plastic granules, the plastic granules can be poured into the surface of the conveying mechanism inside the drying drum from one end of the connecting cover. The conveying mechanism then transports the plastic granules. During the conveying process, the fan blows air into the guide tube. The air blown into the guide tube is heated by the heating wire, and the heated air is blown into the drying drum and blown onto the surface of the plastic granules. This blows away and evaporates the water vapor attached to the surface of the plastic granules. Through the continuous blowing of hot air, the water vapor is blown into the lower half of the drying drum and comes into contact with the dehumidification mechanism, where it condenses into water droplets. The water droplets are then discharged outside the heat insulation drum through the dehumidification mechanism, thus achieving the purpose of removing moisture from the drying drum. The effective removal of moisture helps to further promote the drying of plastic granules and prevents moisture backflow, maintaining the high efficiency of the entire drying process.
[0019] 2. Through the design of the geared motor, drive column, conveyor belt, connecting column, condenser, and liquid guide pipe, during the drying of plastic granules, the geared motor drives the drive column to drive the conveyor belt mounted on the outer surface. This allows the conveyor belt to drive the connecting columns, which are fixedly connected, within the drying drum. The spacing between the connecting columns allows the plastic granules to be placed properly. After hot air blows onto the surface of the plastic granules, the water vapor evaporated from the heat can come into contact with the condenser in the lower half of the drying drum through the spacing between the connecting columns. When the water vapor encounters the surface of the condenser, it cools and condenses. The water droplets form on the surface of the condenser and drip into the lower part of the drying drum for collection. This allows the water stored in the drying drum to flow into the liquid guide pipe and be discharged to the outside through the faucet. Placing the plastic granules between the connecting columns reduces the contact area, allowing the hot air to more evenly contact the surface of each plastic granule, avoiding localized overheating or insufficient drying, thus improving drying efficiency and quality. The contact between the water vapor and the condenser can promptly handle the water vapor generated during the drying process, reducing the humidity inside the drying drum and accelerating the drying process.

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1-5 This embodiment provides the following technical solution:
[0028] like Figures 1-3 As shown, an integrated drying and dehumidification device for plastic granules includes: two sets of connecting covers 103, a heat insulation cylinder 1 fixedly installed between the two sets of connecting covers 103, a drying cylinder 104 connected between the two sets of connecting covers 103, connecting cylinders 102 fixedly installed on both sides of the connecting covers 103, a feeding mechanism 3 rotatably installed inside the connecting cylinder 102, the feeding mechanism 3 rotatably located in the upper half of the drying cylinder 104, and a dehumidification mechanism 2 provided in the lower half of the drying cylinder 104.
[0029] A fan 101 is fixedly installed on the upper surface of the heat insulation cylinder 1, and a guide cylinder 106 is connected to the lower surface of the fan 101. An electric heating wire 105 is fixedly installed inside the guide cylinder 106, and the other end of the guide cylinder 106 is connected to the upper surface of the drying cylinder 104, so that the fan 101 can guide hot air into the drying cylinder 104.
[0030] Ceramic fiber sheets 107 are fixedly connected to both ends of the drying cylinder 104, so that the ceramic fiber sheets 107 can contain the heat inside the drying cylinder 104.
[0031] Through the design of the drying cylinder 104, fan 101, guide cylinder 106, heating wire 105, dehumidification mechanism 2, and conveying mechanism 3, during the drying operation of plastic granules, the plastic granules can be poured from one end of the connecting cover 103 into the surface of the conveying mechanism 3 inside the drying cylinder 104. The conveying mechanism 3 then transports the plastic granules. During the conveying process, the fan 101 blows air into the guide cylinder 106. The blown air enters the guide cylinder 106 and is heated by the heating wire 105, thus facilitating the drying process. Hot air is blown into the drying cylinder 104 and sweeps across the surface of the plastic granules, evaporating the moisture adhering to the surface of the plastic granules. Through continuous blowing of hot air, the water vapor is blown into the lower half of the drying cylinder 104 and comes into contact with the dehumidification mechanism 2, where it condenses into water droplets. The water droplets are then discharged outside the heat insulation cylinder 1 through the dehumidification mechanism 2, thereby achieving the purpose of removing moisture from the drying cylinder 104. The effective removal of moisture helps to further promote the drying of the plastic granules and also prevents the backflow of moisture, maintaining the high efficiency of the entire drying process.
[0032] like Figures 4-5 As shown, the feeding mechanism 3 includes two sets of transmission columns 302, which are rotatably installed in the connecting cylinders 102 of the two sets of connecting covers 103 respectively, and two sets of conveyor belts 303 are fitted on the outer surfaces of the two sets of transmission columns 302.
[0033] A connecting column 304 is fixedly installed between the two sets of conveyor belts 303, so that the connecting column 304 can be driven by the conveyor belt 303 to the upper part of the drying cylinder 104. The spacing between each pair of connecting columns 304 is sufficient to support the plastic granules.
[0034] One set of transmission columns 302 is fixedly connected to the output shaft of the geared motor 301, and the geared motor 301 is fixedly installed at one end of the heat insulation cylinder 1.
[0035] The gap between the connecting columns 304 allows hot air to be blown over to evaporate the water vapor adhering to the surface of the plastic particles. The continuous blowing of hot air also allows the water vapor to come into contact with the dehumidification mechanism 2 through the gap between the connecting columns 304 and condense into water droplets.
[0036] The dehumidification mechanism 2 includes a condenser 202, which is fixedly installed in the lower half of the drying cylinder 104, so that the condenser 202 is located at the lower end of the connecting column 304.
[0037] The lower half of the drying cylinder 104 is connected to a liquid guide pipe 203, and the other end of the liquid guide pipe 203 extends through to the outer surface of the heat insulation cylinder 1 and is connected to a water tap 201.
[0038] The condenser 202 located at the lower end of the connecting column 304 can cool the hot water vapor and condense it into water droplets, which then fall into the lower half of the drying cylinder 104 and flow into the liquid guide pipe 203, from where they are discharged to the outside through the faucet 201.
[0039] Through the design of the geared motor 301, transmission column 302, conveyor belt 303, connecting column 304, condenser 202, and liquid guide pipe 203, when drying plastic granules, the geared motor 301 drives the transmission column 302 to drive the conveyor belt 303 mounted on the outer surface. This allows the conveyor belt 303 to drive the connecting columns 304, which are fixedly connected to it, to rotate inside the drying cylinder 104. The spacing between the connecting columns 304 allows the plastic granules to be placed, and after hot air blows onto the surface of the plastic granules, the water vapor evaporated from the heat can come into contact with the condenser 202 in the lower half of the drying cylinder 104 through the spacing between the connecting columns 304. When the water vapor encounters the surface of the condenser 202... When the condenser 202 is in operation, the water vapor cools and condenses into water droplets. These droplets then drip from the surface of the condenser 202 into the lower half of the drying cylinder 104 for collection. This allows the water droplets stored in the drying cylinder 104 to flow into the liquid guide pipe 203 and be discharged to the outside through the faucet 201. Placing the plastic granules between the connecting columns 304 reduces the contact area, allowing the hot air to more evenly contact the surface of each plastic granule, preventing localized overheating or insufficient drying, thereby improving drying efficiency and quality. The contact between the water vapor and the condenser 202 also helps to promptly handle the water vapor generated during the drying process, reducing the humidity inside the drying cylinder 104 and accelerating the drying process.
[0040] Based on the above technical solution, the working steps of this solution are summarized as follows: When drying plastic granules, the reduction motor 301 can be started to drive the transmission column 302 to drive the conveyor belt 303 mounted on the outer surface. This allows the conveyor belt 303 to drive the connecting columns 304 fixedly connected to it within the drying cylinder 104. The spacing between the connecting columns 304 allows the plastic granules to be placed. Subsequently, the plastic granules can be poured from one end of the connecting cover 103 into the space between the connecting columns 304 within the drying cylinder 104 for placement and conveying. During the conveying of the plastic granules, the fan 101 will blow air into the guide cylinder 106. The blown air enters the guide cylinder 106 and simultaneously passes through... Heating by the heating wire 105 allows heated air to be blown into the drying cylinder 104 and onto the surface of the plastic granules. The hot air evaporates the moisture on the surface of the plastic granules, forming water vapor. The water vapor can come into contact with the condenser 202 in the lower half of the drying cylinder 104 through the gap between the connecting columns 304. When the water vapor encounters the surface of the condenser 202, it cools and condenses into water droplets. The water droplets drip from the surface of the condenser 202 into the lower half of the drying cylinder 104 and are collected. The water droplets stored in the drying cylinder 104 flow into the liquid guide pipe 203 and are discharged to the outside through the faucet 201.
[0041] In summary: placing the plastic granules between the connecting columns 304 reduces the contact area, allowing the hot air to more evenly contact the surface of each plastic granule, thus improving drying efficiency and quality. In particular, the contact between water vapor and the condenser 202 can promptly handle the water vapor generated during the drying process, reducing the humidity inside the drying cylinder 104 and accelerating the drying process.
