Description

Technical Field

[0001] This utility model relates to the field of storage device technology, specifically a modified plastic masterbatch storage device. Background Technology

[0002] Plastic masterbatch refers to granular material produced during plastic processing and molding. For ease of operation, various additives, fillers, and a small amount of carrier resin are mixed and compounded, then processed through equipment such as extruders for metering, mixing, melting, extrusion, and pelletizing. After production, it needs to be stored. Existing storage devices include a modified plastic masterbatch storage device disclosed in CN 218704888 U, which includes a storage silo, a ventilation hood, and a moisture-proof fan. The moisture-proof fan blows real-time moisture-proof air through the ventilation hood onto the masterbatch in the storage silo, and a motor-driven stirring rod rotates to continuously agitate the masterbatch, ensuring uniform moisture-proof airflow and thus improving storage quality.

[0003] However, this existing technology has a drawback: when the humidity of the outside air is high, the dehumidifying blower directly draws in outside air, failing to achieve the dehumidifying effect and instead further reducing the storage quality. Utility Model Content

[0004] This utility model mainly provides a modified plastic masterbatch storage device, which solves the problem that in the existing technology, when the humidity of the outside air is high, the dehumidifying blower directly draws in the outside air, which does not achieve the dehumidifying effect and will further reduce the storage quality.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A modified plastic masterbatch storage device includes an outer shell and a mesh wall inner shell detachably connected to the outer shell. The outer shell has a cover with a stirring mechanism extending into the mesh wall inner shell. An air inlet pipe is located at the bottom of the outer shell and connects to an external low-temperature hot air mechanism. An exhaust pipe with a one-way exhaust valve is located on the outer shell, and an exhaust mechanism is located at the output end of the one-way exhaust valve. The external low-temperature mechanism can utilize existing technology and mainly includes an air filter, a heating element, and a fan. The air filter filters dust and impurities from the outside air, preventing them from entering the outer shell and contaminating the modified plastic masterbatch. The heating element can use a PTC ceramic heating element to heat the air to a set low temperature range, such as 40°C to 60°C, thus ensuring that the plastic masterbatch is not damaged by high temperatures. The fan delivers the filtered and heated low-temperature hot air into the outer shell through the air inlet pipe. The one-way exhaust valve can be any existing technology, as long as it can achieve one-way exhaust. The exhaust mechanism can also be any existing technology, such as an exhaust fan. The mesh wall inner shell refers to a structure with a mesh surrounding the base to form a wall. The base is airtight, and air convection occurs through the mesh wall. The mesh wall inner shell can be detachably connected to the outer shell using any existing method. In use, the modified plastic masterbatch is first placed into the mesh wall inner shell and detachably connected to the outer shell, while the outer shell is sealed with a cover. When moisture protection is required, the external low-temperature hot air mechanism is activated. Outside air is first filtered and heated before being sent into the outer shell through the air inlet pipe to dry the modified plastic masterbatch. At the same time, the stirring mechanism is activated to stir the masterbatch, making the drying more uniform and preventing clumping. When humid air or the input low-temperature hot air needs to be exhausted from the outer shell, it is discharged to the outside through the exhaust pipe by the exhaust fan. Due to the characteristics of the one-way exhaust valve, outside humid air cannot enter the outer shell. This mechanism, through an air inlet pipe connected to an external low-temperature hot air mechanism, allows low-temperature hot air to be introduced into the outer shell to dry the modified plastic masterbatch, preventing it from becoming damp. The stirring mechanism prevents the masterbatch from accumulating and clumping. The one-way exhaust valve and ventilation mechanism can expel humid air while preventing the entry of external humid air. The inner shell of the mesh wall is detachable for easy cleaning and maintenance. By not directly utilizing external air, it effectively solves the problems existing in current storage devices and improves the storage quality of modified plastic masterbatch.

[0007] Furthermore, the stirring mechanism includes a motor mounted on the outer shell, with a stirring shaft at the output end of the motor, and stirring blades mounted on the stirring shaft located within the inner shell of the mesh wall. With this structure, the motor drives the stirring shaft to rotate, thereby causing the stirring blades to stir the modified plastic masterbatch within the inner shell of the mesh wall. The structure is simple and the stirring effect is good.

[0008] Furthermore, an annular air pipe is provided at the bottom of the outer casing, and multiple air outlets are provided on the annular air pipe. The annular air pipe is connected to the air inlet pipe. With this structure, the air inlet pipe delivers low-temperature hot air to the annular air pipe, and then the hot air is evenly distributed into the outer casing through the multiple air outlets, so that the modified plastic masterbatch can be evenly heated and dried.

[0009] Furthermore, a through-hole is provided at the bottom of the outer shell, and a feeding pipe is provided at the lower end of the inner shell of the mesh wall. The feeding pipe extends outside the through-hole and is equipped with a pneumatic butterfly valve. With this structure, the opening and closing of the feeding pipe can be controlled by the pneumatic butterfly valve, which facilitates the feeding operation of modified plastic masterbatch. Moreover, the inner shell of the mesh wall is detachable, which is convenient for cleaning and maintenance.

[0010] Furthermore, a sealing plate is provided on the outer shell above the through-hole, and a sealing groove is provided on the base of the inner shell of the mesh wall to accommodate the insertion of the sealing plate. A sealing strip is provided at the upper end of the sealing plate. With this structure, the sealing plate is inserted into the sealing groove and sealed by the sealing strip, effectively preventing external humid air from entering the outer shell through the through-hole, ensuring a dry storage environment. Moreover, during installation, the sealing plate and sealing groove provide initial positioning and support for the inner shell of the mesh wall.

[0011] Furthermore, a discharge cone surface is provided inside the base of the inner shell of the mesh wall, and the discharge pipe is connected to the lowest end of the discharge cone surface. With this structure, the discharge cone surface allows the modified plastic masterbatch to slide smoothly under the action of gravity and be discharged through the discharge pipe, avoiding masterbatch residue and ensuring smooth discharge.

[0012] Beneficial effects: By setting up an air inlet pipe connected to an external low-temperature hot air mechanism, low-temperature hot air can be introduced into the outer shell to dry the modified plastic masterbatch and prevent the masterbatch from getting damp; the stirring mechanism can prevent the masterbatch from accumulating and clumping; the one-way exhaust valve and ventilation mechanism can exhaust humid air and prevent external humid air from entering; the inner shell of the mesh wall can be detached for easy cleaning and maintenance; by not directly using external air, it effectively solves the problems existing in the current storage device and improves the storage quality of modified plastic masterbatch.

[0019] As shown in Figures 1, 2, and 3, a modified plastic masterbatch storage device according to this embodiment includes an outer shell 1 and a mesh wall inner shell 2 detachably connected to the outer shell 1.

An air inlet pipe 5 is provided at the bottom of the outer shell 1, and the air inlet pipe 5 communicates with an external low-temperature hot air mechanism. An exhaust pipe 6 is provided on the outer shell 1, and the exhaust pipe 6 is provided with a one-way exhaust valve 7.

The stirring mechanism 4 includes a motor mounted on the outer shell 1, and a stirring shaft is provided at the output end of the motor. Stirring blades are provided on the stirring shaft located within the mesh wall inner shell 2. An annular air pipe 9 is provided at the bottom of the outer shell 1, and the annular air pipe 9 has multiple air outlets and communicates with the air inlet pipe 5. The bottom of the outer shell 1 is provided with a through opening, and the lower end of the inner shell 2 of the mesh wall is provided with a feeding pipe 10, which extends to the outside of the through opening.

In use, the modified plastic masterbatch is first placed inside the inner shell 2 of the mesh wall and detachably connected to the outer shell 1, while the outer shell 1 is sealed by the shell cover 3. When moisture protection is required, the external low-temperature hot air mechanism is activated.

Due to the characteristics of the one-way exhaust valve 7, outside humid air cannot enter the outer shell 1.This structure allows for the introduction of low-temperature hot air into the outer shell 1 through an air inlet pipe 5 connected to an external low-temperature hot air mechanism to dry the modified plastic masterbatch and prevent it from becoming damp. The stirring mechanism 4 prevents the masterbatch from accumulating and clumping. The one-way exhaust valve 7 and the ventilation mechanism 8 can exhaust humid air and prevent external humid air from entering. The inner shell 2 of the mesh wall is detachable for easy cleaning and maintenance. By not directly utilizing external air, this structure effectively solves the problems existing in current storage devices and improves the storage quality of modified plastic masterbatch.
