Description

Technical Field

[0001] This utility model relates to the field of plastic particle processing technology, and more specifically, to a plastic particle dryer. Background Technology

[0002] Plastic particles, also known as plastic granules, are raw materials used for storing, transporting, and processing plastics in a semi-finished form. Plastics are a type of polymer material, which can be made from petroleum as a raw material, such as ethylene, propylene, vinyl chloride, and styrene. The molecules of these substances can react with each other under certain conditions to form compounds with very large molecular weights, i.e., polymers. After processing, plastic particles need to be dried to remove moisture and facilitate subsequent storage.

[0003] Patent application number 202420198429.5 discloses a plastic particle dryer, including a base. A drying chamber is slidably connected to the top right side of the base. Multiple heating rods are installed inside the drying chamber. Connecting blocks are fixedly connected to the front and rear ends and left and right sides of the drying chamber. Connecting rings are rotatably connected inside each of the four connecting blocks. Two connecting seats are fixedly connected to the front and rear ends of the base. Telescopic rods are rotatably connected inside each of the four connecting seats. Compression components are fixedly connected to the tops of the four telescopic rods. Protective shells are slidably connected to the outer sides of the telescopic rods. The dryer improves maintenance efficiency by allowing for quick disassembly, reduces downtime, and increases production efficiency. Quantitative blocking and leveling of piled plastic particles improves drying uniformity and efficiency.

[0004] Regarding the aforementioned technologies, the efficiency of maintenance is improved by quickly disassembling the drying device, and the uniformity and efficiency of drying are improved by quantitatively blocking and flattening the piles of plastic particles. However, when the equipment dries plastic particles, the plastic particles are exposed and emit an unpleasant odor during drying. This odor spreads throughout the workshop, which may not only cause environmental pollution but also affect the health of the workers. Utility Model Content

[0005] To solve the above problems, this utility model provides a plastic particle dryer, which adopts the following technical solution: A plastic particle dryer includes a tank body, a top cover at the top of the tank body, a frame fixedly fitted on the side wall of the top cover, a heating component inside the frame, a branch pipe fixedly installed at the top of the top cover, a guide cylinder connected to the top of the branch pipe, a feed pipe connected to the side wall of the guide cylinder, a limiting component inside the guide cylinder, a stirring component inside the tank body, a discharge pipe fixedly installed at the bottom of the tank body, and a control valve on the lower side wall of the tank body. A blower pump and a frame are fixedly installed at the top of the top cover. One end of the blower pump is connected to the side opposite to the frame. An exhaust pipe is fixedly installed on the side of the frame away from the blower pump. The exhaust pipe passes through the top cover at the end away from the frame. A connecting pipe is fixedly installed on the lower side wall of the tank. Dustproof cotton is installed inside the connecting pipe. A conduit is fixedly connected between the connecting pipe and one end of the blower pump. A filter assembly is installed inside the frame.

[0006] By adopting the above technical solution, the equipment can be operated using the control mechanism in existing technology. Operators can connect the material extraction mechanism to the feed pipe, and then the material extraction mechanism guides the plastic particles into the guide cylinder through the feed pipe. The guide cylinder is equipped with a material limiting component, facilitating the batch dropping of material into the tank through branch pipes. Once the material enters the tank, heat is generated by the heating component, and the heat is conducted into the tank, thus heating and drying the plastic particles. Furthermore, the stirring component agitates the material inside the tank, ensuring thorough mixing of the material and heat, which improves the drying efficiency of the plastic particles. When the equipment is drying the plastic particles, odors and moisture may be generated; these are addressed by operating the exhaust pump. Gas is extracted from inside the tank and enters the frame through the extraction pipe. The frame is equipped with a filter to filter out odors and moisture from the gas, thus purifying it. The purified gas then re-enters the tank through the conduit and connecting pipe, allowing the heated gas to further dry the plastic particles, improving heat utilization and reducing energy waste. Both the extraction pipe and the connecting pipe can be equipped with one-way valves, facilitating unidirectional gas flow. The inner wall of the connecting pipe, away from the conduit, is lined with dustproof cotton made of a high-hardness material to prevent plastic particles from entering the connecting pipe. Once the material is dried, the control valve at the bottom of the tank can be opened to allow the material to be discharged through the discharge pipe.

[0007] Furthermore, the heating assembly includes a sealing plate disposed on the top of the sleeve frame, a conductive plate disposed at the bottom of the sealing plate, and a plurality of heating wires arranged in a ring array at the bottom end of the conductive plate. The sealing plate and the sleeve frame are fixed together by a first bolt, and a heat insulation layer is sleeved on the side wall of the sleeve frame.

[0008] By adopting the above technical solution, the side wall of the tank is equipped with a frame, and a heating wire is installed inside the frame. Heat can be generated through the heating wire, and the heat is transferred to the inside of the tank and comes into contact with the material, which can play the role of heating and drying the material. The side wall of the frame is equipped with a heat insulation layer, which helps to reduce the amount of heat loss and helps to prevent workers from being injured by accidental contact.

[0009] Furthermore, the material limiting component includes a baffle disposed on one side of the guide cylinder, a protective box fixedly installed on the side of the baffle away from the guide cylinder, a second reduction motor fixedly installed inside the protective box, a rotating rod rotatably installed inside the guide cylinder, a plurality of material limiting plates arranged in a ring array fixedly installed on the side wall of the rotating rod, and one end of the rotating rod penetrating into the protective box and fixedly connected to the end of the output shaft of the second reduction motor.

[0010] By adopting the above technical solution, after the material enters the guide cylinder through the feed pipe, the rotating rod is driven to rotate by the second reduction motor. The rotating rod drives multiple limiting plates to rotate synchronously. Through the cooperation of multiple limiting plates, the material can enter the tank in batches, which is conducive to improving the mixing efficiency of material and heat, and thus improving the drying efficiency of the material.

[0011] Furthermore, the stirring assembly includes a support rod rotatably mounted on the inner wall of the top of the top cover, a spiral blade fixedly sleeved on the lower side wall of the support rod, multiple scrapers arranged in a circular array slidably mounted on the inner wall of the upper section of the tank, two symmetrically distributed connecting rods fixedly mounted between each scraper and the side wall of the support rod, a stirring frame fixedly mounted between the two connecting rods on the same side, an installation box fixedly mounted on the top of the top cover, a first reduction motor fixedly mounted inside the installation box, and the top of the support rod penetrating into the installation box and fixedly connected to the end of the output shaft of the first reduction motor.

[0012] By adopting the above technical solution, after the material enters the tank, the first reduction motor drives the support rod to rotate. The support rod, along with the connecting rod, stirring frame, scraper, and spiral blade, rotates synchronously, which can agitate the material, facilitate the full mixing of the material and heat, and improve the drying efficiency of the material. In addition, the spiral blade not only agitates the material, but also causes the material at the bottom of the tank to surge upward, which is convenient for subsequent agitation. Furthermore, when the spiral blade is driven to rotate in the reverse direction, it can convey the material, thus achieving the effect of assisting in the discharge of the material.

[0013] Furthermore, the filter assembly includes multiple purification plates disposed within a frame, the frame containing symmetrically distributed filter cotton and drying plates, and a cover plate on the top of the frame, the cover plate being fixed to the frame by a second bolt.

[0014] By adopting the above technical solution, the filter cotton and drying plate inside the frame can filter water vapor in the gas, and the multiple purification plates can filter unpleasant odors in the gas. The purification plates can be made of existing materials, and the staff can change the material of the purification plates according to the substances that need to be removed from the gas, which helps to maintain the purification effect of the equipment and reduce the pollution of the equipment to the environment.

[0015] Furthermore, two symmetrically distributed inserts are fixedly installed at the bottom of the purification plate, filter cotton, and drying plate. The inner wall of the top of the frame is provided with a slot that matches the insert on the same side. A sealing gasket is fixedly installed at the bottom of the cover plate.

[0016] By adopting the above technical solution, the bottom of the purification plate, filter cotton and drying plate are all provided with inserts. The inserts engage with the slots opened on the inner wall of the bottom of the frame. The cooperation between the inserts and the slots serves to position the purification plate, filter cotton and drying plate. In addition, the bottom of the cover plate is provided with a sealing gasket. The sealing gasket not only helps to maintain the airtightness of the cover plate and the frame, but also helps to hold the purification plate, filter cotton and drying plate in place, which helps to maintain the stability of the placement of the purification plate, filter cotton and drying plate.

[0017] Furthermore, a plurality of positioning rods arranged in a circular array are fixedly installed at the bottom of the top cover, and a positioning groove matching the positioning rods is provided at the top of the tank body.

[0018] By adopting the above technical solution, the top cover and the tank body are fixed together with fasteners of existing technology, and the bottom of the top cover is provided with a positioning rod. The positioning rod engages with the positioning groove opened at the top of the tank body to position the top cover, which facilitates subsequent fixing.

[0019] In summary, this utility model has the following beneficial technical effects: (1) In this utility model, the gas inside the tank is drawn into the frame by the exhaust fan. The frame is equipped with a filter assembly. Through the cooperation of the purification plate, filter cotton and drying plate, the gas is filtered and purified.
