Description

Technical Field

[0001] This utility model belongs to the technical field of plastic pellet production equipment, specifically a temporary storage warehouse for plastic fragments. Background Technology

[0002] In the process of manufacturing plastic pellets from recycled plastics, the plastic fragments (flakes, blocks) after crushing and washing typically have a high moisture content and are loose in volume. These fragments are then removed through processes such as breaking them up and blowing them out, awaiting further input into the melting equipment. Currently, the common practice for temporarily storing these plastic fragments is to pile them up in large quantities in the open or on the ground of the production workshop. When it is necessary to feed them into subsequent equipment, manual shoveling and handling are the primary methods used, resulting in high labor intensity, poor working conditions, and low transfer efficiency, severely restricting the overall capacity of the production line. Furthermore, open-air stockpiling of materials is susceptible to secondary pollution, occupies a large amount of ground space, and is detrimental to factory planning and management. At the same time, the large amount of manual shoveling and handling also increases production costs.

[0003] Therefore, there is a need to design a device that can centrally store plastic fragments and facilitate mechanical transport to subsequent transfer devices to reduce labor intensity. Utility Model Content

[0004] To address the above technical problems, this utility model provides a device that can centrally store plastic fragments and facilitate mechanical transport to subsequent transfer devices to reduce labor intensity, thereby solving the problem that existing plastic fragments piled on the ground require manual shoveling and handling, which involves high labor intensity.

[0005] To solve the above technical problems, the technical solution of this utility model is as follows: a temporary storage warehouse for plastic fragments, including a temporary storage warehouse, a base plate fixedly connected to the bottom of the temporary storage warehouse, a transport warehouse provided at the rear of the temporary storage warehouse, and the temporary storage warehouse having at least one open corner structure; on the two adjacent walls constituting the open corner structure, a door opening is respectively opened, and each door opening is hinged with a first folding door and a second folding door that can be opened outward; when the first folding door and the second folding door are opened simultaneously, an open passage is formed leading to the corner area inside the temporary storage warehouse, an inlet is opened on the upper side of the temporary storage warehouse, an outlet is opened at the rear, a top cover is provided on the top of the temporary storage warehouse, and the warehouse wall is a mesh structure.

[0006] Furthermore, each of the two adjacent sides of the temporary storage compartment is vertically fixedly connected to a support column, and the first folding door and the second folding door are both hinged to the side of the support column. A load-bearing beam is horizontally fixedly connected between the two support columns.

[0007] Furthermore, the first folding door and the second folding door are folding structures composed of multiple door panels connected sequentially by hinges, and the upper ends of the first folding door and the second folding door abut against the bottom surface of the load-bearing beam.

[0008] Furthermore, an inclined slope is provided on the ground opposite the open corner structure, and the upward inclined end of the inclined slope is detachably connected to the base plate.

[0009] Furthermore, the first folding door and the second folding door are equipped with door lock mechanisms.

[0010] Furthermore, the top opening of the transport compartment is connected to the discharge window, and a door is hinged to the discharge window.

[0011] This utility model has the following advantages compared with the prior art:

[0012] 1. This utility model, by incorporating a temporary storage compartment, allows for the temporary storage of cleaned and broken plastic fragments within a single container, preventing these fragments from being blown into the production workshop and occupying significant space. The open corner structure, along with a double-folding corner door, creates a spacious mechanical passageway, allowing small forklifts to directly enter the storage compartment for mechanized operations, completely replacing inefficient manual handling. A transport compartment is connected to the temporary storage compartment, with a discharge window on the rear wall of the temporary storage compartment, enabling forklifts to shovel plastic fragments from the temporary storage compartment into the transport compartment. The transport compartment has a certain capacity, allowing for a 3-4 hour rest period after each shoveling operation, reducing the frequency of manual labor and improving transfer capacity. Mechanized operations within the temporary storage compartment significantly reduce the labor intensity of workers, improve the working environment, and reduce reliance on a large number of manual laborers, thereby lowering labor costs.

[0013] 2. This utility model makes targeted modifications to the door structure of traditional warehouses. By setting support columns and load-bearing beams on the walls of the temporary storage warehouse, an open corner structure that allows for the entry and exit of forklifts is formed, providing conditions for the mechanized shoveling and transportation of plastic fragments.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 5 The illustrated plastic scrap temporary storage warehouse includes a temporary storage bin 1. A base plate 3 is fixedly connected to the bottom of the temporary storage bin 1. The base plate 3 is welded from I-beam steel plates, possessing sufficient rigidity to support the movement of a small forklift. The base plate 3 is designed to be flat. To facilitate the transfer of plastic scrap stored in the temporary storage bin 1 to a transport bin 2 via a forklift, reducing manual labor intensity, a transport bin 2 is located behind the temporary storage bin 1. The transport bin 2 can hold 2-3 buckets' worth of plastic scrap, and a conveyor belt at the bottom of the transport bin 2 transports the plastic scrap to a melting device. This allows for 3-4 hours of operation without manual shoveling after a single shovel operation, saving work frequency and reducing manual labor intensity. To facilitate forklift access and shoveling within the temporary storage bin 1, the temporary storage bin 1 has at least one open corner structure. The open corner structure can be located at the two corners in front of the temporary storage bin 1, on the two adjacent walls forming the open corner structure. Each storage bin 1 has a doorway 4, allowing a forklift to enter from one side. Each doorway 4 is hinged with a first folding door 5 and a second folding door 6 that can be opened outwards. When the first folding door 5 and the second folding door 6 are opened simultaneously, they form an open passage leading to the corner area inside the storage bin 1, facilitating the forklift to turn around and perform other operations inside the storage bin 1. This allows for easy shoveling and transport of plastic in the corner area inside the storage bin 1. The storage bin 1 has a feed inlet 7 on the upper side and a discharge window 12 at the rear. A pipe is installed at the feed inlet 7. After the washed plastic fragments are filtered and dispersed by a dispersing device at the front, a blower blows the plastic fragments into the storage bin 1 through the pipe at the feed inlet 7. To prevent the plastic fragments blown into the storage bin 1 from flying out, a top cover 11 is installed on the top of the storage bin 1, and the bin walls are made of a mesh structure. All bin walls are made of filter mesh, which allows the gas blown into the storage bin 1 to be discharged quickly.

[0022] In order to support the first folding door 5 and the second folding door 6 and fit perfectly with the door opening 4, support columns 8 are vertically fixedly connected to the middle of the two adjacent sides of the temporary storage compartment 1. The first folding door 5 and the second folding door 6 are hinged to the sides of the support columns 8. A load-bearing beam 9 is horizontally fixedly connected between the two support columns 8. The two support columns 8, the first folding door 5, the second folding door 6 and the load-bearing beam 9 above them together form an open corner structure.

[0023] In order to facilitate opening the doors and save the external space occupied when opening, the first folding door 5 and the second folding door 6 are folding structures composed of multiple door panels connected in sequence by hinges. The upper ends of the first folding door 5 and the second folding door 6 abut against the bottom surface of the load-bearing beam 9.

[0024] In order to facilitate the entry of the forklift into the temporary storage bin 1, an inclined slope 10 is provided on the ground where the open corner structure tends to be. The inclined slope 10 is smoothly connected to the upper surface of the base plate 3 at one end, which facilitates the entry of the forklift into the temporary storage bin 1. The inclined slope 10 is detachably connected to the base plate 3 by means of a pin or bolt.

[0025] In order to facilitate the opening and closing of the first folding door 5 and the second folding door 6, a door lock mechanism is provided on the first folding door 5 and the second folding door 6. The door lock mechanism is set with an existing common door lock. Each door is provided with a rotatable rotating rod with a handle. The load-bearing beam 9 and the base plate 3 are provided with buckles that cooperate with the upper and lower ends of the rotating rod to facilitate locking the door.

[0026] In order to shovel the plastic fragments in the temporary storage bin 1 into the transport bin 2, the top opening of the transport bin 2 is connected to the discharge window 12, and the discharge window 12 is hinged with a door 13. The other three sides of the transport bin 2 that are not close to the temporary storage bin 1 are equipped with protective nets at the same height as the side walls of the temporary storage bin 1 to prevent the plastic fragments from flying to other places.

[0027] The specific working process of this utility model is as follows:

[0028] After the plastic fragments are washed and broken up, a blower blows them from the inlet 7 into the temporary storage bin 1. Once a certain amount of plastic fragments has accumulated in the temporary storage bin 1, the blower is stopped, and the first folding door 5 and the second folding door 6 are opened. Workers drive a small forklift to the outside of the warehouse. The forklift enters from the inclined slope 10 and drives directly into the temporary storage bin 1 through the open passage formed by two adjacent doorways 4. The forklift scoops the plastic fragments from the temporary storage bin 1 into the bucket, and then extends the forklift bucket from the discharge window 12 and positions it in the transport bin 2. Above, pour the plastic fragments into transport bin 2. Continue shoveling and transporting the plastic fragments in the transport bin 2 until it is full. At this time, the conveyor belt at the bottom of transport bin 2 slowly transports the plastic fragments, which can continue for 3-4 hours without the need for personnel to continue shoveling and transporting plastic fragments. This can free up personnel and reduce the labor intensity. Then, reverse out of the warehouse and close the first folding door 5 and the second folding door 6 through the door lock mechanism on each door. Blow plastic fragments into temporary storage bin 1 again, and repeat the above operation when it is necessary to shovel plastic fragments into transport bin 2.
