Description

Technical Field

[0001] This utility model relates to the technical field of plastic granule drying equipment, and in particular to an automatic drying device for plastic granules used in the production of electrofusion pipe fittings. Background Technology

[0002] In modern industrial production, electrofusion fittings are key components for connecting plastic pipes, and their quality directly affects the stability and safety of the entire pipeline system. Electrofusion fittings mainly consist of a plastic pipe body, resistance wires embedded in the inner wall of the pipe, and electrodes for energizing the resistance wires. The welding principle involves generating heat through the energized resistance wires, melting the plastic materials of the fittings and the pipes to be connected, thus achieving pipe fusion. With the widespread application of plastic pipes in water supply and drainage, gas transmission, and chemical industries, more stringent requirements have been placed on the performance and quality of electrofusion fittings.

[0003] A typical automatic plastic granule drying device consists of a conveying mechanism, a drying mechanism, and a discharge mechanism. The plastic granules are stably conveyed to the drying mechanism by a screw conveyor. The drying mechanism uses a hot air system to fully contact the plastic granules in a closed cavity and remove moisture. The discharge mechanism conveys the qualified granules to the next stage via a screw conveyor, ensuring stable output quality.

[0004] In some existing devices used in the production of electrofusion pipe fittings, the drying quality of plastic granules plays a crucial role in the molding quality and performance of the fittings. However, these devices lack efficient heat recovery systems, resulting in a significant amount of heat being directly released into the external environment during the drying process. This not only leads to substantial energy waste but also increases production costs for enterprises. Therefore, an automatic plastic granule drying device for the production of electrofusion pipe fittings is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic drying device for plastic granules used in the production of electrofusion pipe fittings, which aims to improve the problems of uneven material drying and heat energy waste in some existing devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic drying device for plastic granules used in the production of electrofusion fittings includes a transfer pipe. A separation mechanism is located at the top of the transfer pipe, and a drying mechanism is located at the bottom of the transfer pipe. The drying mechanism includes a drying chamber. A partition plate is fixedly connected inside the drying chamber. Multiple processing chambers are opened inside the drying chamber. Recycling frames are fixedly connected to both sides of the outside of the drying chamber. A collection port is fixedly connected to the top of each recycling frame. Hot air nozzles are fixedly connected to the bottom inside the processing chambers. Inclined plates are fixedly connected to the inner walls of the drying chamber. A discharge pipe is fixedly connected to the bottom of the drying chamber. An air supply assembly is fixedly connected to the outside of the collection port. A heating assembly is fixedly connected to the outside of the drying chamber. A material distribution assembly is fixedly connected inside the transfer pipe.

[0008] As a further description of the above technical solution:

[0009] The separation mechanism includes a mixing tank, the bottom of which is fixedly connected to the top of the transfer pipe, a hopper fixedly connected to the outer top side of the mixing tank, a differential fixedly connected to the top of the mixing tank, a drive motor fixedly connected to the top of the differential, and a drive rod fixedly connected to the output end of the drive motor.

[0010] As a further description of the above technical solution:

[0011] A flap is fixedly connected to the outside of the drive rod, and a baffle is fixedly connected to the inner wall of the mixing tank;

[0012] As a further description of the above technical solution:

[0013] The material distribution assembly includes a support plate, the outside of which is fixedly connected to the inside of the adapter pipe, and the inside of which is fixedly connected to a tapered opening;

[0014] As a further description of the above technical solution:

[0015] The air supply assembly includes two exhaust pipes, with the adjacent sides of the two exhaust pipes fixedly connected to the distant sides of the two central inlets, and the bottom of each hot air nozzle is fixedly connected to an air inlet pipe.

[0016] As a further description of the above technical solution:

[0017] The heating assembly includes a gas distribution zone, the outside of which is fixedly connected to the outside of the drying chamber, a heating zone is fixedly connected to the top of the gas distribution zone, and a return gas zone is fixedly connected to the top of the heating zone.

[0018] As a further description of the above technical solution:

[0019] The other end of the air inlet pipe is fixedly connected to the bottom of the air distribution zone, and the other ends of the two exhaust pipes are fixedly connected to the left and right sides of the air return zone, respectively.

[0020] As a further description of the above technical solution:

[0021] The top outer sides of the two processing chambers are fitted into the receiving port of the recycling frame, the receiving end of the discharge pipe is fixedly connected to the bottom of the multiple processing chambers, and a support frame is fixedly connected to the bottom of the drying chamber.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the particles are evenly distributed to the two processing chambers of the drying chamber through the conical structure. The hot air generated by the heating component is sprayed into the processing chamber through the hot air nozzle at the bottom of the processing chamber. At the same time, the inclined plate guides the particles to slide towards the middle of the processing chamber at an inclined angle. During the sliding process, the particles come into full contact with the hot air sprayed from the nozzle, and the moisture gradually evaporates. The humid and hot air generated during the drying process rises and is filtered through the recovery frame on the outer side of the top of the processing chamber. The humid and hot air is collected through the collection port, thereby achieving the effect of efficient particle drying and humid and hot air circulation treatment.

[0024] 2. In this utility model, the high-speed rotation output of the drive motor is reduced and increased in torque by the differential, and the drive rod drives the flap to rotate. The interlacing of the flap and the baffle forces the particles to form a compound motion of axial downward pushing and radial disturbance in the tank. The baffle hinders the rotational inertia of the particles, so that when the agglomerated particles collide with the baffle, they are combined with the mechanical extrusion of the flap to achieve physical crushing and dispersion at the same time. This solves the problems of centrifugal accumulation of particles, dead corners of mixing, and ineffective dispersion of agglomerated particles caused by a single rotation direction in the mixing equipment.

A hot air nozzle 46 is fixedly connected to the bottom inside the processing chamber 43, which sprays hot air evenly. An inclined plate 47 is fixedly connected to the inner wall of the drying chamber 41, which guides the particles to slide towards the middle of the processing chamber 43 to prevent accumulation. A discharge pipe 48 is fixedly connected to the bottom of the drying chamber 41 for discharging materials. An air supply assembly 6 is fixedly connected to the outside of the collection port 45. A heating assembly 5 is fixedly connected to the outside of the drying chamber 41. A material distribution assembly 3 is fixedly connected to the inside of the transfer pipe 1.

[0034] The top outer sides of the two processing chambers 43 are fitted into the receiving port of the recycling frame 44, the receiving end of the discharge pipe 48 is fixedly connected to the bottom of the multiple processing chambers 43, and the bottom of the drying chamber 41 is fixedly connected to the support frame 7, which supports the entire device and ensures the stability of the equipment.

[0035] The material distribution assembly 3 includes a support plate 31, with a fixed conical opening 32. The outside of the support plate 31 is fixedly connected to the inside of the transfer pipe 1, and the inside of the support plate 31 is fixedly connected to the conical opening 32, which evenly disperses the particles to the two processing chambers 43 on both sides. The air supply assembly 6 includes two exhaust pipes 62, which draw hot and humid air back to the heating assembly 5. The adjacent sides of the two exhaust pipes 62 are fixedly connected to the distant sides of the two central inlets 45, respectively. The bottom of each hot air nozzle 46 is fixedly connected to an air inlet pipe 61. The air duct 61 delivers hot air to the nozzle. The heating assembly 5 includes an air distribution zone 51, which evenly distributes hot air. The air distribution zone 51 is fixedly connected to the outside of the drying chamber 41. A heating zone 52 is fixedly connected to the top of the air distribution zone 51. The heating zone 52 heats the air. A return air zone 53 is fixedly connected to the top of the heating zone 52.

The other ends of the two exhaust ducts 62 are fixedly connected to the left and right sides of the return air zone 53, respectively.

[0036] Reference Figure 1 and Figure 2 The separation mechanism 2 includes a mixing tank 21, which stores plastic granules and performs preliminary mixing to prevent granule agglomeration and prepare for subsequent drying.

During the process, the granules are in full contact with the hot air sprayed from the nozzle, and the moisture gradually evaporates.

[0038] Heating zone 52 of heating component 5 heats the air and then distributes it evenly to air inlet pipe 61 through air distribution zone 51, driving hot air nozzle 46 to spray hot air into processing chamber 43. The hot and humid air generated during the drying process rises and is filtered through recovery frame 44 on the outer side of the top of processing chamber 43. The hot and humid air is collected by collection port 45 and then transported to return air zone 53 through exhaust pipe 62. After dehumidification, it is circulated back to heating zone 52. Support frame 7 supports the overall structure to ensure stable operation of equipment. Finally, the dried particles are discharged through discharge pipe 48.
