Description

Technical Field

[0001] This utility model relates to the field of plastic granule drying technology, specifically a plastic granule drying and dehumidification circulation system. Background Technology

[0002] As is well known, plastic granules need to be dried during the production process to remove moisture and ensure their stable performance in subsequent processing such as injection molding and extrusion. In traditional drying equipment, multiple drying chambers often share an independent dehumidification device, such as a dehumidifier. The dehumidifier needs to provide dry air to multiple drying chambers simultaneously, resulting in uneven airflow distribution among the chambers. Some chambers may not dry completely due to insufficient airflow. Moist air often flows back to other drying chambers in the shared duct due to pressure difference, causing the plastic granules in other drying chambers to become damp. When a drying chamber needs emergency dehumidification, the shared equipment has difficulty quickly adjusting the airflow and humidity parameters, affecting production efficiency. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model relates to a plastic granule drying and dehumidification circulation system, comprising a drying chamber body 1, which is equipped with a dehumidification mechanism, a ventilation mechanism, a heating mechanism, and a storage mechanism. The dehumidification mechanism includes a dehumidification chamber 2, and a sliding mechanism is provided between the dehumidification chamber 2 and the drying chamber body 1. A sealing groove is formed on one side of the dehumidification chamber 2, and a sealing chamber 3 is provided on the sealing groove. An adsorption layer 4 is provided inside the sealing chamber 3, and openings are formed on both sides of the sealing chamber 3. Air guide chambers 5 are formed on both sides of the sealing groove, and a fan 6 is provided on the air guide chambers 5. 5. An air guiding mechanism is provided inside the drying chamber body 1. A drain pipe 7 is provided between the bottom end of the dehumidification chamber 2 and the sealing groove. An assembly mechanism is provided between the dehumidification chamber 2 and the sealing chamber 3. In this embodiment, plastic granules can be placed inside the drying chamber body 1 using a storage mechanism. Then, the inside of the drying chamber is heated using a heating mechanism, and waste heat is recovered through an external heat exchange device connected to the ventilation mechanism, thereby achieving the drying treatment of the plastic granules. The waste heat recovery device is a common heat exchange and recovery device in the prior art, which will not be described in detail in this structure. By turning on the fans 6 on the air guide chambers 5 of the two dehumidification chambers 2, the fan 6 in one air guide chamber 5 delivers air from inside the drying chamber 1 to the sealed groove through the air guide mechanism. The air then enters the adsorption layer 4 through the opening of the sealed chamber 3 to adsorb moisture from the air, thus achieving the effect of adsorbing and filtering moisture. The fan 6 in the other air guide chamber 5 discharges the dehumidified and filtered air back into the drying chamber 1 through the air guide mechanism, thereby achieving dehumidification of the interior of the drying chamber 1. The moisture adsorbed by the adsorption layer 4 is discharged through the sealed groove and the drain pipe 7 at the bottom of the dehumidification chamber 2. The sliding mechanism and assembly mechanism facilitate the assembly and disassembly of the sealing box 3 and the dehumidification box 2, and facilitate the replacement of the adsorption layer 4. This structure enables the drying box body 1 to perform independent dehumidification, solving the problem that in traditional plastic granule drying equipment, multiple devices are connected to an external dehumidification and drying device for drying and dehumidification, resulting in slow dehumidification and easy conduction of moisture to other plastic granule drying equipment. The sealing between the dehumidification box 2 and the drying box body 1 is set by the sealing strip commonly used in the prior art. The sealing technology is known to those skilled in the art and will not be described in detail in this structure.

[0024] To facilitate the entry of air from inside the drying chamber 1 into the air guide cavity 5, in this design, the air guide mechanism includes an air guide hole 8. The air guide hole 8 is located at the bottom of the drying chamber 1 and above the air guide cavity 5. The air guide hole 8 is equipped with a barrier net 9. The air guide hole 8 allows air from inside the drying chamber 1 to enter the air guide cavity 5, while the barrier net 9 prevents plastic particles from falling into the air guide cavity 5.

[0025] To facilitate positioning the dehumidifier 2 below the drying chamber body 1, in this design, the sliding mechanism includes a slide groove and a slide rail 10. The slide groove is located at the bottom end of the drying chamber body 1, and the slide rail 10 is located in the slide groove and connected to the top end of the dehumidifier 2. Both the slide groove and the slide rail 10 are provided in two sets and are symmetrically arranged. By inserting the slide rail 10 into the slide groove, the dehumidifier 2 can be positioned at the bottom end of the drying chamber body 1, which facilitates the use of an assembly mechanism to fix the dehumidifier 2 onto the drying chamber body 1.

[0026] To facilitate the assembly of the dehumidifier box 2 and the sealing box 3, the assembly mechanism in this design includes an adjustment hole, a sloping groove, a threaded hole, and a limiting hole. The adjustment hole is located on the sealing box 3 and connects to its top and bottom. The sloping groove is located at the bottom of the drying box body 1. The threaded hole is located at the top of the sealing groove and connects to the top of the dehumidifier box 2. The limiting hole is located at the bottom of the sealing groove and connects to the bottom of the dehumidifier box 2. An adjustment post 11 is provided between the limiting hole and the adjustment hole. The top of the adjustment post 11 is sequentially provided with a sealing plug 12, a threaded post 13, and a cone 14. The threaded post 13 is threadedly connected to the threaded hole, and the cone 14 abuts against the sloping groove. When the dehumidifier box 2 is positioned at the bottom of the drying box body 1 via the sliding mechanism, the air guide mechanism aligns with the air guide cavity 5, and the sloping groove aligns with the threaded hole. Then, the sealing box 3 is inserted into the sealing groove. Pushing the adjusting column 11 upward in the limiting hole allows the sealing plug 12 of the adjusting column 11 to match the adjusting hole, enabling the cone 14 to pass through the threaded hole. Then, rotating the adjusting column 11 allows the threaded column 13 of the adjusting column 11 to be threadedly connected to the threaded hole. The adjusting column 11 rotates upward, causing the cone 14 to contact and abut against the inclined groove, thus assembling the dehumidification box 2 at the bottom of the drying box body 1. The angle of the inclined groove and the cone 14 generate a lateral thrust, ensuring that the dehumidification box 2 is more stably positioned at the bottom of the drying box body 1 through the sliding mechanism. By using one adjusting column 11, the dehumidification box 2 and the sealing box 3 can be fixedly assembled. When it is necessary to replace the adsorption layer 4 of the sealing box 3, simply move the threaded column 13 away from the threaded hole and then push the adjusting column 11 downward, so that the sealing plug 12 abuts against the top of the limiting hole. Personnel can then directly remove the sealing box 3 for replacement, making it convenient to use.

[0027] To ensure effective heating of the air inside the drying chamber 1, the heating mechanism in this design includes heating tubes 15, which are installed inside the drying chamber 1. Multiple heating tubes 15 are arranged in an array, which improves the heating effect of the air inside the drying chamber 1 and further enhances the drying process.

[0028] To facilitate ventilation of the drying chamber body 1, in this design, the ventilation mechanism includes a ventilation pipe 16. The ventilation pipe 16 is installed at the top of the drying chamber body 1 and connects to the interior. The ventilation pipe 16 is equipped with a valve 17. There are two ventilation pipes 16 arranged symmetrically. The valves 17 on the ventilation pipes 16 allow for easy opening and closing of the ventilation pipes 16 for ventilation. The two ventilation pipes 16 are connected to the heat exchange equipment, which facilitates the recovery of heat inside the drying chamber body 1 and provides ventilation, thus facilitating the drying process.

[0029] To facilitate the storage of plastic granules, the storage mechanism in this design includes a breathable partition 18 located inside the drying chamber body 1. Supporting components are provided between the two sides of the breathable partition 18 and the inner wall of the drying chamber body 1. Multiple breathable partitions 18 are provided, and by placing them in corresponding positions with the supporting components, the breathable partitions 18 can be stored inside the drying chamber body 1. The drying process of the plastic granules is carried out through the breathable partitions 18. The breathable partitions 18 can store the plastic granules while simultaneously providing ventilation, thus improving the airflow and drying effect on the plastic granules.

[0030] In order to facilitate the detection of humidity on the inner wall of the drying chamber body 1 and the air guide cavity 5, in this solution, humidity sensors 19 are provided on the inner wall of the drying chamber body 1 and the air guide cavity 5. The humidity can be easily detected through the humidity sensors 19 on the inner wall of the drying chamber body 1 and the air guide cavity 5.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
