Abstract
Description
Technical Field
[0001] This utility model relates to the field of dehumidifying dryer technology, and in particular to a dehumidifying dryer mechanism with dew point monitoring function. Background Technology
[0002] To ensure the smooth progress of the plastic molding process and the quality of the molded products, the moisture content of the plastic granules must be strictly controlled below 0.02%. To achieve this, using a honeycomb rotary dehumidifier dryer capable of generating low-dew-point dehumidifying air is essential.
[0003] However, conventional honeycomb rotary dehumidifiers currently on the market have significant shortcomings. These devices often only undergo dew point testing before leaving the factory to verify whether their basic performance meets standards. However, during actual use, customers cannot monitor the equipment's dew point performance in real time. Due to the lack of real-time monitoring, operators often fail to detect when the equipment fails to reach the required dew point value due to various factors (such as component aging or environmental changes). This affects the quality of the dried material, resulting in inadequate drying. Poorly dried plastic granules directly entering subsequent molding processes inevitably lead to various defects in the molded products, such as bubbles and cracks, severely impacting product quality. This not only wastes a large amount of dried material due to substandard quality but also disrupts subsequent molding operations, requiring significant manpower and resources for troubleshooting and adjustments, while also causing unnecessary energy waste. Utility Model Content
[0004] To address the technical problems existing in the background art, this utility model proposes a dehumidification and drying mechanism with dew point monitoring function.
[0005] This utility model proposes a dehumidification and drying mechanism with dew point monitoring function, including a base plate, an upper aluminum plate above the base plate, a dew point transmitter mounted on the upper part of the upper aluminum plate, and the detection end of the dew point transmitter extending into the interior of the upper aluminum plate; a honeycomb dehumidification wheel is rotatably connected between the base plate and the upper aluminum plate, and a lower aluminum plate is mounted at the bottom of the base plate corresponding to the position of the honeycomb dehumidification wheel; the rotation of the honeycomb dehumidification wheel is driven by a synchronous belt drive device mounted on the base plate.
[0006] Furthermore, a through hole is provided in the middle of the seat plate, and a bearing is provided in the through hole. The seat plate is connected to the honeycomb dehumidification rotor through the bearing, and the bottom end of the honeycomb dehumidification rotor extends to the bottom of the seat plate through the through hole, located inside the lower aluminum disc.
[0007] Furthermore, the top of the upper aluminum plate is connected to a low dew point dehumidifying air outlet pipe and a regenerated humidifying air outlet pipe, respectively, and the bottom of the lower aluminum plate is connected to a humidifying air inlet pipe.
[0008] Furthermore, the seat plate and the upper aluminum plate are connected and fixed by several tie bolts, and a spring is provided at the top of the tie bolt and between it and the upper aluminum plate.
[0009] Furthermore, the synchronous belt drive device includes a motor installed at the bottom of the base plate and several toothed plates installed on the side of the honeycomb dehumidification wheel. The drive end of the motor extends to the upper part of the base plate and is equipped with a synchronous pulley. The synchronous pulley and the several toothed plates are connected by a synchronous belt.
[0010] Furthermore, each of the toothed plates is configured as an arc-shaped toothed plate, which is adapted to the arc surface of the honeycomb dehumidification wheel, and the teeth of the toothed plate are adapted to the teeth of the synchronous belt.
[0011] Furthermore, the synchronous belt drive device also includes a tension adjustment wheel rotatably connected to the top of the seat plate, the surface of which is in contact with the outer side of the synchronous belt.
[0012] The beneficial effects of this utility model are as follows: By setting a dew point transmitter on the upper aluminum plate and extending its detection end into the mechanism, the dew point value of the airflow after drying can be monitored in real time, enabling operators to grasp the dehumidification performance of the equipment in a timely manner, avoiding poor drying of plastic granules due to the equipment not meeting the dew point requirements, thereby ensuring the smooth progress of subsequent plastic molding operations, effectively reducing the waste of manpower, material resources and energy caused by poor materials and molding, and significantly improving production efficiency and product quality stability.

[0018] Reference Figure 1-4This utility model proposes a dehumidification and drying mechanism with dew point monitoring function, which mainly includes a base plate 1, an upper aluminum disc 2, a lower aluminum disc 5, a honeycomb dehumidification wheel 4, and a synchronous belt drive device 7. Specifically:
[0019] An upper aluminum plate 2 is provided above the seat plate 1. The upper aluminum plate 2 is connected and fixed to the seat plate 1 by several tie bolts 6. To ensure the stability of the connection, a spring 61 is also provided between the top of the tie bolt 6 and the upper aluminum plate 2, which can play a certain buffering role. A through hole is reserved in the middle of the seat plate 1. A bearing is installed in the through hole. The honeycomb dehumidifying wheel 4 is rotatably connected to the seat plate 1 through the bearing. The bottom end of the honeycomb dehumidifying wheel 4 extends to the bottom of the seat plate 1 through the through hole and is located inside the lower aluminum plate 5. The lower aluminum plate 5 is fixedly installed at the bottom end of the seat plate 1 and corresponds to the position of the honeycomb dehumidifying wheel 4.
[0020] The top of the upper aluminum plate 2 is connected to a low dew point dehumidifying air outlet pipe 21 and a regenerated humid air outlet pipe 22, respectively, and the bottom of the lower aluminum plate 5 is connected to a humid air inlet pipe 51.
[0021] The synchronous belt drive device 7 is used to drive the rotation of the honeycomb dehumidification wheel 4. It includes a motor 71 mounted at the bottom of the base plate 1 and several toothed plates 72 mounted on the side of the honeycomb dehumidification wheel 4. The drive end of the motor 71 extends to the upper part of the base plate 1 and is equipped with a synchronous pulley 73. The synchronous pulley 73 and the several toothed plates 72 are connected by a synchronous belt 74. Each toothed plate 72 is set as an arc-shaped toothed plate and is adapted to the arc surface of the honeycomb dehumidification wheel 4. The teeth of the toothed plate 72 are adapted to the teeth of the synchronous belt 74 to ensure that the synchronous belt 74 can stably drive the toothed plates 72 and the honeycomb dehumidification wheel 4 to rotate. The synchronous belt drive device 7 also includes a tension adjustment wheel 75 rotatably connected to the top of the base plate 1. The surface of the tension adjustment wheel 75 is in contact with the outer surface of the synchronous belt 74. By adjusting the distance between the tension adjustment wheel 75 and the honeycomb dehumidification wheel 4, the tension of the synchronous belt 74 can be adjusted, thereby ensuring the transmission efficiency of the synchronous belt 74.
[0022] During operation, the motor 71 starts, driving the honeycomb dehumidifying rotor 4 to rotate via the synchronous pulley 73, synchronous belt 74, and toothed plate 72. Moist airflow enters the lower aluminum disc 5 through the moist air inlet duct 51, and then enters the interior of the honeycomb dehumidifying rotor 4. The honeycomb dehumidifying rotor 4 utilizes its own honeycomb-shaped absorbent material to absorb moisture from the airflow, thereby drying it.
[0023] The dried airflow is discharged through the low dew point dehumidified air outlet duct 21 and the regenerated humidified air outlet duct 22. Before being discharged, the dried airflow passes through the detection end of the dew point transmitter 3. The dew point transmitter 3 monitors the dew point temperature of the airflow in real time and outputs the drying data to the control panel via a 4-20mA signal. The control panel displays the current dew point value so that the operator can understand the dehumidification effect in real time.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
