Description

Technical Field

[0001] This utility model relates to the field of plastic storage, and in particular to an adjustable silo. Background Technology

[0002] Plastic raw materials are usually processed into plastic granules for storage. During long-term storage, they often become damp and clump together. At the same time, the production of plastic products often requires plastic granules of different colors and types, so how to preserve plastic granules has become a problem.

[0003] Chinese utility model patent CN222539506U discloses a storage silo for modified plastic granules, including a silo and a stirring assembly. The silo stores the modified plastic granules, the stirring assembly prevents the granules from accumulating for a long time, a collection assembly collects fallen granules, a positioning assembly fixes the collection cart, and a filtering assembly filters the granules by size. This increases the flowability and uniformity of the modified plastic granules inside the silo, facilitating collection. However, a drawback is that the stored plastic granules can still become damp. Using damp plastic granules for injection molding, compression molding, or other processing can lead to cracking, holes, watermarks, and other defects in the finished product, affecting product quality. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable hopper that can directly supply dried plastic granules, while also storing and fully mixing plastic granules of different colors and types to meet different needs.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable hopper, including a base support and a base disposed above the base support, the base having a hollow cavity, and a plurality of hopper placement openings communicating with the cavity on the upper surface of the base, each hopper placement opening being movably connected to a mixing hopper, a through air inlet on one side of the base, the air inlet pipe being connected to a drying fan, a plurality of through air outlets on the side of the base opposite to the air inlet, and a mixing discharge mechanism disposed below the base, the mixing discharge mechanism being disposed on the side near the air outlets.

[0006] By adopting the above technical solution, after the long-term stored humid plastic granules enter the cavity from the mixing hopper, the drying fan blows dry airflow from the air inlet to remove the moisture on the surface of the plastic granules and discharges them from the air outlet. After a period of time, the plastic granules are completely dried and discharged from the discharge port of the lower base for subsequent use. If it is necessary to mix different colored plastic granules or add some modifiers, the required number of mixing hoppers can be installed at the hopper placement port of the base.

[0007] The present invention is further configured as follows: the mixing hopper includes a hopper body and a motor mounted on the hopper body, a top cover is hinged to the top of the hopper body, a horizontally rotatable mixing mechanism is installed inside the hopper body, the mixing mechanism is controlled to rotate by the motor, a mixing hopper outlet is provided at the bottom of the hopper body, and an electric mixing hopper outlet valve is provided at the mixing hopper outlet.

[0008] By adopting the above technical solution, plastic granules are prone to clumping and arching due to moisture during long-term storage. The top cover of the silo can prevent the plastic granules from getting damp to a certain extent. By setting a rotary stirring mechanism in the mixing silo, the damp and clumped plastic granules can be broken up and discharged from the discharge port of the mixing silo below. By installing an electric mixing silo discharge port valve, the valve opening and closing degree can be controlled, which can conveniently and accurately control the amount of plastic granules discharged. The electric mixing silo discharge port valve is existing technology.

[0009] A further feature of this invention is that the stirring mechanism includes a stirring shaft, which is coaxially and fixedly connected to the output end of a motor. Several sets of stirring rods are radially connected to the stirring shaft, and each set of stirring rods is simultaneously connected to a stirring scraper at its end. The stirring scraper is parallel to the stirring shaft.

[0010] By adopting the above technical solution, when the stirring mechanism rotates, the stirring rod and the stirring scraper rod can stir most of the area of ​​the hopper, preventing plastic particles from clumping at the edge of the hopper and affecting discharge.

[0011] A further feature of this invention is that: a fixing seat is provided on the outer surface of the compartment to cooperate with the placement port; the fixing seat is detachably connected to the placement port; a sealing ring is provided on the edge of the placement port; a plurality of through upper screw holes are provided on the fixing seat; and a lower screw hole is provided on the upper part of the placement port to cooperate with the upper screw holes, so that the fixing seat and the placement port can be fixedly connected by detachable bolts.

[0012] By adopting the above technical solution, the mixing hopper is placed from above the base downwards at the placement opening when needed. The sealing ring at the edge of the placement opening can prevent the drying airflow from leaking out from the gaps and thus affecting the drying effect. Connecting the mixing hopper and the base with bolts can prevent the mixing hopper from falling out due to vibration during operation.

[0013] The present invention is further configured such that: the mixing and discharging mechanism includes a particle mixing and drying zone and a base discharge port disposed below the particle mixing and drying zone, the base discharge port is hinged with a base discharge port valve, and a particle lifting mechanism that can rotate horizontally is provided in the particle mixing zone.

[0014] By adopting the above technical solution, the plastic granules discharged from the mixing hopper may still clump together due to moisture. At the same time, a large number of plastic granules accumulating at the bottom of the cavity will reduce the surface area in contact with the airflow, making it difficult to dry with airflow. By installing a lifting mechanism, the plastic granules can be lifted up, the clumps can be broken up, and the contact area with the airflow can be increased. At the same time, plastic granules of different colors can be fully mixed after being lifted multiple times.

[0015] A further feature of this invention is that the inner wall of the particle mixing and drying zone is semi-circular, and the particle lifting mechanism includes a rotating shaft with blades evenly arranged radially on the rotating shaft to lift the plastic particles.

[0016] By adopting the above technical solution, the inner wall of the particle mixing and drying zone is set to a semi-circular arc shape so that the blades can always be in contact with the inner wall, thereby lifting more plastic particles.

[0017] A further feature of this invention is that the bottom surface of the cavity is inclined downwards along the direction from the air inlet to the air outlet.

[0018] By adopting the above technical solution, after the plastic granules are discharged from the mixing hopper, they fall onto the inclined bottom surface of the cavity and slide down into the granule mixing and drying zone under the action of gravity.

[0019] A further feature of this invention is that: a particle scraper is provided at the bottom of the cavity, which can slide close to the inclined bottom surface; a cylinder is provided below the air inlet of the cavity, which can push the particle scraper to slide; and a grounding wire is connected to the outside of the cylinder.

[0020] By adopting the above technical solution, the plastic particles may generate static electricity by rubbing against each other when they fall, and then stick to the cavity base. The particle scraper can push the sticky plastic particles into the particle mixing and drying zone. At the same time, the particle scraper and the cylinder are integral metal structures. When the cylinder is grounded, the particle scraper can eliminate the static electricity of the plastic particles it touches, reducing the degree of plastic particle adhesion. At the same time, the cross-section of the particle scraper can be set to be arc-shaped to prevent some of the plastic particles brought back by the particle scraper from getting stuck in the gap between the cylinder and the particle scraper when the particle scraper pushes back.

[0021] A further feature of this invention is that each placement port is provided with a detachably connected sealing cap, and the sealing cap is sealed to the placement port by a sealing ring.

[0022] By adopting the above technical solution, if some placement ports do not need to be connected to the mixing silo, sealing caps can be installed on these placement ports to prevent leakage of the drying airflow.

[0023] A further feature of this invention is that: one side of the air outlet connecting to the cavity is detachably provided with an intercepting net that prevents plastic particles from passing through, and the other side of the air outlet is detachably provided with an airtight cover that can prevent airflow from passing through.

[0024] By adopting the above technical solution, the interception net prevents small plastic particles from being blown out of the cavity. At the same time, the interception net is detachable for easy cleaning or replacement. When the dried plastic particles are discharged from the discharge port of the base, the airtight cover of the air outlet can be closed, and the drying airflow will help blow out the plastic particles that are stuck to the cavity wall.

[0025] The beneficial effects of this utility model are:

[0026] 1. The wet plastic granules can be dried in the granule mixing and drying zone inside the base, which facilitates further processing of the plastic granules.

[0027] 2. Different colors of plastic granules can be stored and mixed as needed for further processing.

[0028] 3. After drying and expelling the plastic granules, any remaining plastic granules in the base will be discharged under the combined action of the granule scraper and the drying airflow, leaving no residue and facilitating the drying and mixing of the next batch of plastic granules.

[0048] S1: Determine the quantity of different types of plastic granules to be stored, fix the required mixing hoppers to the base with bolts, and install sealing caps at the other placement openings. Store the different types of plastic granules in the mixing hoppers separately, and cover the top of the mixing hoppers with the top cover.

[0049] S2: When the stored plastic granules need to be used, turn on the motor. The stirring mechanism will break up the clumps of plastic granules to facilitate discharge from the outlet of the mixing chamber. Control the opening and closing angle of the outlet valve of the electric stirring chamber to control the discharge volume. The plastic granules falling into the chamber fall into the granule mixing and drying zone under the combined action of gravity, the drying airflow and the granule scraper. They are continuously lifted by the rotating blades of the granule lifting mechanism. The plastic granules are broken up, thereby increasing the contact area with the drying airflow, which helps to dry quickly. At the same time, plastic granules of different colors are evenly mixed together after repeated stirring.

[0050] S3: After the drying and mixing are complete, close the airtight cover at the air outlet, open the valve at the base outlet, and discharge the plastic particles through the base outlet below. At the same time, the drying air will also be discharged from the base outlet, which helps to blow out the plastic particles that are stuck to the inner wall of the cavity.
