[0001] The utility model relates to plastic particle processing technical field more specifically, relate to a kind of drying mechanism of plastic particle granulation processing. BACKGROUND
[0002] Plastic particle, also known as plastic particle, is granular high molecular material processed by mixing synthetic resin and various additives. It is regular in shape, easy to store, transport and process, and is the basic raw material for plastic product production. Plastic particles are widely used in packaging, construction, electronics, automobiles, medical and other fields. Through injection molding, extrusion, blow molding and other processes, plastic films, pipes, toys, electrical enclosures and other products can be produced.
[0003] In order to remove the moisture in the plastic particles, drying treatment is needed. Currently, hot air is mainly used to remove the moisture in the plastic particles. The plastic particles are in a stacked state in the drying equipment. The hot air is difficult to fully penetrate the material layer, making it difficult for the internal moisture of the plastic particles to evaporate effectively, which can cause uneven drying and reduce drying efficiency. In view of this, a drying mechanism for plastic particle granulation processing is proposed. SUMMARY
[0004] The utility model aims to overcome the shortcomings of the prior art, meet the needs of reality, and provide a drying mechanism for plastic particle granulation processing to solve the technical problem that the plastic particles are in a stacked state in the drying equipment, the hot air is difficult to fully penetrate the material layer, making it difficult for the internal moisture of the plastic particles to evaporate effectively, which can cause uneven drying and reduce drying efficiency.
[0005] To solve the above technical problems, the utility model provides the following technical scheme: a drying mechanism for plastic particle granulation processing, including drying box and setting in drying box's drying mechanism, the space in drying box is circularly arranged, the upper end of drying box is provided with feed pipe, the drying mechanism includes rotating shaft that rotates and installs in the inner wall of the front end of drying box and drying plate that installs in drying box, the front end of drying box is provided with motor that drives rotating shaft, the rotating shaft is provided with fixed rod in array, the end of fixed rod is provided with hopper, the drying plate divides drying box into material cavity and air cavity.
[0006] Preferably, the front end of the drying box is provided with a discharge port, and the discharge port is provided with a box door.
[0007] Preferably, the rear end of the drying box is provided with a gas cover communicated with the drying box, and a fan is installed on the gas cover.
[0008] Preferably, an electric heating wire is provided at the rear of the drying chamber, the electric heating wire is located in the air cavity, and the position of the electric heating wire corresponds to the connection between the drying chamber and the air hood.
[0009] Preferably, the drying plate includes a feeding section and a drying section. The feeding section is inclined downward along the long axis. The front part of the feeding section includes symmetrically arranged notches, and the tail part of the feeding section has a feeding port.
[0010] Preferably, the drying section is bent at 90 degrees and located at the end of the feeding section. The drying section has air-permeable micropores. The drying section is composed of several bent sections along its long axis. The bent sections are L-shaped, and several bent sections are connected to form a stepped shape.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, through the design of a hopper structure, uses the synergistic action of a rotating shaft and the hopper to transport the plastic granules accumulated at the bottom of the drying chamber upwards, allowing them to continuously circulate through the drying plate and preventing material accumulation. Combined with the stepped structure of the drying section, hot air can not only enter the material layer through the permeable micropores but also rise from the bottom of the plastic granule pile, directly drying the granules. This avoids the problem of insufficient drying in certain areas, ensuring that the internal moisture of the plastic granules evaporates fully. It solves the problem of current drying equipment where plastic granules are piled up, making it difficult for hot air to fully penetrate the material layer, resulting in uneven drying and reduced drying efficiency.
[0013] 2. This utility model also features a drying plate structure. The feeding section of the drying plate can be repeatedly fed into the hopper, and the notch provides space for the hopper to rotate. The plastic granules sliding down the feeding section can control the feeding speed, preventing too much material from reaching the drying section at once. Secondly, the drying section of the drying plate is composed of several L-shaped bends connected to form a stepped shape, so that the plastic granules are distributed in a stepped manner on the drying section, preventing the plastic granule layer from being too thick. Hot air can evenly contact the plastic granules and blow directly onto the plastic granules in all positions. Furthermore, the special space formed by the drying plate requires the hot air to bypass the feeding section when it is discharged, increasing the time that the air stays in the space inside the drying chamber, allowing the hot air to have more sufficient contact with the plastic granules, thereby quickly removing the moisture from the plastic granules and greatly improving the drying efficiency.

Detailed Implementation
[0021] like Figures 1 to 6 As shown, this utility model relates to a drying mechanism for plastic granule processing, including a drying chamber 101 and a drying mechanism 200 disposed within the drying chamber 101. The space inside the drying chamber 101 is circular, and a feed pipe 104 is provided at the upper end of the drying chamber 101. The drying mechanism 200 includes a rotating shaft 201 rotatably mounted on the inner wall of the front end of the drying chamber 101 and a drying plate 205 installed inside the drying chamber 101. A motor 204 driving the rotating shaft 201 is provided at the front end of the drying chamber 101. Fixed rods 202 are arranged in an array on the rotating shaft 201, and a hopper 203 is provided at the end of the fixed rods 202. The drying plate 205 divides the interior of the drying chamber 101 into a material chamber and an air chamber. This utility model avoids the accumulation of plastic granules by using the hopper 203 and the drying plate 205. In conjunction with the stepped structure of the drying plate 205, hot air can fully penetrate the material layer. The special structure of the drying plate 205 controls the feeding and extends the residence time of hot air, effectively solving the problem of uneven drying and significantly improving drying efficiency.
[0022] Specifically, the drying chamber 101 has a discharge port 102 at its front end, and a door 103 is installed at the discharge port 102. A pull ring is installed at the front end of the door 103. After the plastic granules are dried, the door 103 is opened to discharge them from the discharge port 102.
[0023] Furthermore, an air hood 106 connected to the rear end of the drying chamber 101 is installed, and a fan 107 is installed on the air hood 106. The air outlet pipe of the fan 107 is connected to the air hood 106. When the fan 107 operates, it blows air into the air hood 106, which disperses the air into the drying chamber 101 to prevent gas from concentrating.
[0024] It is worth noting that an electric heating wire 105 is installed at the rear of the drying chamber 101. The electric heating wire 105 is located inside the air cavity, and its position corresponds to the connection between the drying chamber 101 and the air hood 106. When outside air enters the drying chamber 101, the electric heating wire 105 operates to heat the air, thereby generating hot air. The hot air enters the plastic granules through the permeable micropores on the drying section 207 to dry them.
[0025] It is worth mentioning that the drying plate 205 includes a feeding part 206 and a drying part 207. The feeding part 206 is inclined downward along the long axis. The front part of the feeding part 206 includes symmetrically arranged notches 2061, and the rear part of the feeding part 206 has a feeding port 2062. During feeding, the plastic granules enter the drying chamber 101 and fall onto the drying plate 205. Under the action of the inclined feeding part 206, they slide down to the feeding port 2062 and then fall onto the drying section 207. Secondly, when the rotating shaft 201 rotates, the hopper 203 can convey the plastic granules at the bottom of the drying chamber 101 upwards, which can prevent the material from accumulating and not drying sufficiently. The upward plastic granules will fall onto the feeding part 206 and then pass through the drying section 207 for drying again, ensuring the drying effect of the plastic granules and allowing the moisture to be fully evaporated. Furthermore, the special internal space of the drying chamber 101 formed by the drying plate 205 requires the hot air to bypass the feeding part 206 before being discharged from the feeding pipe 104, increasing the time that the air stays in the internal space.
[0026] It is worth noting that the drying section 207 is bent at 90 degrees and located at the end of the feeding section 206. The drying section 207 has permeable micropores and is composed of several bent sections 2071 along its long axis. These bent sections 2071 are L-shaped, and the connection of several bent sections 2071 forms a stepped shape. The stepped shape of the drying section 207 prevents the plastic granule layer from becoming too thick at various locations on the drying section 207. Air can be directly blown onto the plastic granules through the permeable micropores, evenly drying them and quickly removing moisture. Furthermore, hot air entering from the bottom of the drying section 207 can be blown into the accumulated plastic granule layer, coordinating with the upward conveying of the plastic granules by the hopper 203, allowing hot air to rise from the granule pile and directly dry the plastic granules.
[0027] Working Principle: This embodiment provides a drying mechanism for plastic granule processing. In use, the fan 107 starts, blowing external air into the air hood 106. The air hood 106 disperses the air into the air chamber of the drying chamber 101. When the air passes through the electric heating wire 105 located within the air chamber, corresponding to the connection between the drying chamber 101 and the air hood 106, the electric heating wire 105 heats the air, forming hot air. This hot air can be blown into the drying chamber 101 through the permeable micropores on the drying section 207. The plastic granules pass through... The feed pipe 104 enters the drying chamber 101 and falls onto the discharge section 206 of the drying plate 205. Since the discharge section 206 is inclined downwards along its long axis, the plastic granules will naturally slide down along the discharge section 206 and fall onto the drying section 207 through the discharge port 2062. Simultaneously, the motor 204 drives the rotating shaft 201 to rotate, and the fixed rod 202 drives the hopper 203 at the end to rotate synchronously. The hopper 203 scoops up the plastic granules accumulated at the bottom of the drying chamber 101 and conveys them upwards. After the plastic granules are lifted to a certain height... The plastic granules will fall back onto the feeding section 206 and re-dry in the drying section 207. This cycle ensures that the plastic granules are thoroughly dried. Because the drying section 207 is composed of several L-shaped bends 2071 connected to form a stepped shape, the plastic granules slide down the drying section 207 in a stepped distribution, preventing the granule layer from becoming too thick. Hot air can evenly contact the plastic granules, quickly removing moisture. Simultaneously, hot air entering from the bottom of the drying section 207 blows into the accumulated granule layer, facilitating the drying of the compound material. The upward conveying of plastic granules by bucket 203 allows hot air to rise from the granule pile, further ensuring that the granules are thoroughly dried. In addition, the special space formed by the drying plate 205 requires the hot air to bypass the feeding section 206 before exiting through the feed pipe 104, increasing the time the air stays inside the drying chamber 101 and improving the drying effect. After the plastic granules are dried, the chamber door 103 is opened, and the dried plastic granules are discharged from the discharge port 102, completing the entire drying process.
