Description

Drying device for plastic granules

technical field

The utility model relates to the technical field of plastic processing, in particular to a drying device for plastic particles.

Background technique

In the plastic manufacturing industry, due to the dryness of plastic particles is closely related to the transparency of the final product, color purity, mechanical properties including bending, torsion, elasticity, tension index, yield, etc., and electrical properties including insulation, conductivity, etc. , so it is very important to dry the plastic pellets before they are fed into the injection molding machine, extruder, blister machine or other plastic processing machinery. The traditional drying method is to spread the plastic granules to cool or blow dry, which has low efficiency and heavy workload, and it is difficult to fully dry the plastic granules, which will have a certain impact on subsequent processing.

Utility model content

The purpose of the utility model is to overcome the defects of the prior art and provide a drying device for plastic granules, which has a simple structure and utilizes vibration dispersion to keep the plastic granules in a dispersed state and facilitate the drying process.

The technical scheme that the utility model adopts is:

A drying device for plastic granules, comprising a cylindrical shell, the shell is installed on a vibrating table, the hot air inlet is located at the bottom of the left side of the shell, and the feeding hopper and the air outlet are located at the top of the shell. It is characterized in that: The casing is provided with a distribution plate, a water receiving tray, at least four sieve plates and a material receiving plate in sequence from top to bottom, and the material distribution plate, sieve plate and material receiving plate are composed of a skeleton and a mesh cloth wrapped on the skeleton and , a connecting pipe is provided at the vertical center position of the distribution plate and the water receiving tray so that the area above the distribution plate and the area below the water receiving tray are connected, and 1 to 5 discharge holes are uniformly provided on each sieve plate , The material receiving plate is installed obliquely inside the bottom of the shell, and the discharge port is located under the right side of the shell and is flush with the lowest point of the material receiving plate. The discharge holes on two adjacent sieve plates are vertically staggered, so that plastic particles can stay on different sieve plates and increase the drying time. A conical buffer ring is installed above the discharge hole, so that the residence time of the plastic particles on the same sieve plate is prolonged.

Further, a drain port is provided on the upper left side of the outer wall of the housing, and the drain port communicates with the water receiving tray for releasing the water collected by the water receiving tray.

Further, an auxiliary air outlet is provided on the shell wall in the region of the water receiving tray and the adjacent sieve plate, and the decompression operation is performed from the auxiliary air outlet when the pressure in the shell is too high.

The beneficial effects of the utility model are:

The plastic particles enter the hopper into the casing, and the cloth plate is vibrated, and the plastic particles are evenly dispersed, and at the same time, the vibration makes the water carried by the plastic particles fall into the water receiving tray. When the plastic particles pass through the sieve plate, they are dried in contact with hot air and finally discharged. The utility model has a simple structure, utilizes the vibration dispersion effect to keep the plastic particles in a dispersed state, and is beneficial to the drying process.

detailed description

In order to make the purpose of the utility model and the advantages of the technical solution clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and examples.

As shown in Figure 1, a plastic particle drying device is characterized in that it includes a cylindrical shell 1, the shell 1 is installed on the vibrating table 2, the hot air inlet 3 is located at the left bottom of the shell 1, and the feeding hopper 4 and the air outlet 15 are located on the top of the housing 1, and the housing 1 is sequentially provided with a distribution plate 5, a water receiving tray 6, at least four sieve plates 7 and a material receiving plate 8, and the distribution plate 5. The sieve plate 7 and the material receiving plate 8 are composed of a skeleton and a mesh cloth wrapped on the skeleton. A connecting pipe 9 is provided at the vertical center of the distribution plate 5 and the water receiving tray 6 to make the distribution plate The area above 5 is connected to the area below the water receiving tray 6, and 1 to 5 discharge holes 10 are evenly provided on each sieve plate 7, and the material receiving plate 8 is installed obliquely on the inner side of the bottom of the shell 1, and the discharge port 11 is located in the shell The lower right side of the body 1 is flush with the lowest point of the inclination of the receiving plate 8 . A drain port 12 is provided on the upper left side of the outer wall of the housing 1 and the drain port 12 communicates with the water receiving tray 6 . An auxiliary air outlet 13 is provided on the wall of the housing 1 in the region of the water receiving tray 6 and the adjacent sieve plate 7 . The discharge holes 10 on two adjacent sieve plates 7 are arranged alternately in the vertical direction. A conical buffer ring 14 is installed above the discharge hole 10 .

The working principle of the utility model is:

The plastic particles to be processed enter the housing 1 from the hopper 4 and fall onto the distribution plate 5 , and are dispersed by the vibration of the vibrating table 2 . The plastic particles fall onto the sieve plate 7 through the connecting pipe 9, and then fall over the buffer ring 14 from the discharge hole 10 to the next sieve plate 7. The plastic sieve plate 7 is in contact with the hot air blown in from the hot air inlet 3 during the vibration and jumping process to realize the drying process. After drying, the plastic granules fall onto the inclined material receiving plate 8, and then are released from the discharge port 11.
