Description

Technical Field

[0001] This application belongs to the field of plastic processing technology, specifically relating to a drying device for plastic production. Background Technology

[0002] In existing technologies, drying equipment for plastic production plays a crucial role in the plastics processing industry. It effectively removes moisture from plastic granules, ensuring the stable quality and performance of plastic products. However, current drying equipment for plastic production on the market has some shortcomings that urgently need to be overcome.

[0003] While traditional hot air drying devices can remove moisture from the surface of plastic granules and achieve drying, their drying efficiency is unsatisfactory. Firstly, existing hot air drying devices have poor drying uniformity, easily leading to inconsistent drying levels of the plastic granules, or even excessively high drying temperatures causing the plastic granules to melt, severely reducing the consistency of subsequent plastic product quality. Secondly, existing drying devices do not easily collect the plastic granules in batches after drying, significantly reducing the overall drying efficiency.

[0004] While existing vacuum drying equipment offers good drying performance, rapidly removing moisture from plastic granules in a vacuum environment with relatively fast drying speed and high drying quality, its high equipment and maintenance costs, including energy consumption and maintenance expenses for key components such as vacuum pumps, place a heavy economic burden on some small and medium-sized plastic production enterprises. Furthermore, vacuum drying equipment is complex to operate, requiring a high level of professional skill from operators; improper operation can easily lead to equipment malfunctions or unsatisfactory drying results.

[0005] Therefore, in order to comprehensively improve the drying efficiency, drying quality, cost-effectiveness, and ease of operation of drying equipment used in plastic production, it is now urgent to make improvements to better adapt to the rapid development needs of the plastic production industry and improve the production efficiency and quality stability of plastic products.

[0027] Combination Figures 1-8 The following description further illustrates the technical solution proposed in this application. This application provides a drying device for plastic production, including a drying tank 1, a drive assembly 2 disposed on the drying tank 1, a cage 3 disposed on the output end of the drive assembly 2 and located inside the drying tank 1, a hot air drying assembly 4 disposed on the drying tank 1, and a rotation stabilizing assembly 5 disposed between the drying tank 1 and the cage 3. The cage 3 is used to contain plastic granules to be dried, the drive assembly 2 is used to drive the cage 3 to rotate relative to the drying tank 1, and the hot air drying assembly 4 is used to deliver hot air into the drying tank 1 to remove moisture from the surface of the plastic granules to be dried.

[0028] This application provides a drying device for plastic production, comprising a drying tank, a drive assembly mounted on the drying tank, a cage located inside the drying tank and at the output end of the drive assembly, a hot air drying assembly mounted on the drying tank, and a rotation stabilizing assembly positioned between the drying tank and the cage. Plastic granules to be dried can be placed inside the cage. The drive assembly drives the cage to rotate within the drying tank, and the hot air drying assembly delivers hot air into the drying tank to remove surface moisture from the plastic granules. By setting the drive assembly to rotate the cage, and cooperating with the rotation stabilizing assembly to ensure stable cage rotation, the uniformity of drying of the plastic granules is effectively improved, increasing drying efficiency and quality. The hot air drying assembly delivers hot air specifically to effectively remove moisture, and the dried plastic granules can be more easily recycled during rotation within the cage. This device has the advantages of reasonable design, good drying effect, easy recycling of plastic granules, and ease of widespread implementation.

[0029] In this embodiment, the hot air drying assembly 4 includes a blower 40, a first branch pipe 41 disposed on the output end of the blower 40, a second branch pipe 42 disposed on the output end of the blower 40, and a heating wire 43 disposed between the first / second branch pipe and the blower 40. The first / second branch pipe is connected to the drying tank 1. The blower 40 is used to deliver airflow to the first / second branch pipe, and the heating wire 43 is used to heat the airflow generated by the blower 40.

[0030] In actual implementation, after the drive component 2 is started, the cage 3 begins to rotate relative to the drying tank 1. This rotation causes the plastic granules to be dried to tumble continuously within the cage 3. On the one hand, it can shake off the moisture on the surface of the plastic granules to be dried from the cage; on the other hand, it can spread the plastic granules to be dried out through centrifugal force, increasing the contact area between the plastic granules and the hot air, thereby improving the uniformity and efficiency of hot air drying.

[0031] In actual implementation, blower 40 generates airflow, which enters the first branch pipe 41 and the second branch pipe 42 through the output end of blower 40. Before the airflow enters the branch pipes, heating wire 43 begins heating. Heating wire 43 heats the airflow generated by blower 40 into hot air. The heated hot air enters the drying tank 1 through the first branch pipe 41 and the second branch pipe 42. Inside the drying tank 1, the hot air comes into contact with the plastic granules in the cage 3, carrying away the moisture on the surface of the plastic granules. Due to the high temperature of the hot air, it can quickly evaporate the moisture on the surface of the plastic granules.

[0032] In actual implementation, by placing the rotation stabilizing component 5 between the drying tank 1 and the cage 3, the cage 3 may be affected by various forces during its rotation, such as the impact force of airflow and the centrifugal force of plastic particles. The rotation stabilizing component 5 can effectively reduce the impact of these forces on the rotational stability of the cage 3, ensuring that the cage 3 can rotate smoothly and avoiding uneven distribution of plastic particles or damage to the drying device due to shaking. It significantly improves the drying uniformity of the plastic particles to be dried and avoids excessive heat concentration.

[0033] In this embodiment, the first branch pipe 41 is located above the second branch pipe 42.

[0034] In actual implementation, a temperature sensor is installed inside the drying tank to sense the temperature inside the drying tank.

[0035] In actual implementation, a buzzer is connected to the temperature sensor. When the temperature value sensed by the temperature sensor exceeds the preset value, the buzzer sounds.

[0036] In this embodiment, a flow guiding component 6 is also provided between the first / second branch pipe and the cage 3. The flow guiding component 6 is used to guide the hot airflow to the cage 3. The flow guiding component 6 includes a first flow guiding plate 60 and a second flow guiding plate 61 provided on the inner wall of the drying tank 1. The first flow guiding plate 60 is located above the second flow guiding plate 61. The first flow guiding plate 60 is inclined towards the first branch pipe 41, and the second flow guiding plate 61 is inclined towards the second branch pipe 42.

[0037] In this embodiment, an air outlet 7 is provided on the side of the drying tank 1 away from the hot air drying component 4. The air outlet 7 is provided in multiple spaces along the length and width of the drying tank 1.

[0038] In actual implementation, the flow guiding components ensure that hot air is evenly distributed throughout the cage 3, preventing uneven drying in certain areas. Compared to designs without flow guiding components, this structure significantly improves drying efficiency while maintaining the drying quality of the plastic granules.

[0039] In actual implementation, the design of the air outlet 7 also helps maintain airflow circulation within the drying tank 1, facilitating the removal of moisture from the drying tank and further optimizing the drying environment. Good airflow circulation can remove more moisture and accelerate the drying speed.

[0040] In this embodiment, the rotational stabilizing component 5 includes a mounting ring 50 located in the drying tank 1 at the corresponding position of the cage 3, a mounting post 51 on the mounting ring 50, and stabilizing balls 52 rolling on the mounting post 51. Multiple mounting posts 51 are symmetrically arranged relative to the axis of the mounting ring 50.

[0041] In this embodiment, the cage 3 includes an upper cage 30, a lower cage 31 disposed on the upper cage 30, a receiving cavity 32 disposed between the upper cage 30 and the lower cage 31, and a connecting assembly 33 disposed between the upper cage 30 and the lower cage 31. The plastic granules to be dried are disposed in the receiving cavity 32, and the lower cage 31 is detachably disposed on the upper cage 30 through the connecting assembly 33.

[0042] In actual implementation, by setting the cage into an upper cage and a lower cage, it is easier to subsequently recycle the dried plastic particles in the containment cavity, thereby improving drying efficiency.

[0043] In this embodiment, the height of the upper cage 30 is defined as H, and the height of the lower cage 31 is defined as h. The relationship between H and h is as follows: 1.5≤H / h≤2.5.

[0044] In this embodiment, the connecting component 33 includes an upper flange 34 on the upper cage 30, a lower flange 35 on the lower cage 31, a connecting hole group 36 between the upper flange 34 and the lower flange 35, and fasteners on the connecting hole group 36.

[0045] In this embodiment, the drying tank 1 includes a tank body 10, a cover 11 disposed on the tank body 10, and support legs 12 disposed on the tank body 10. Multiple support legs 12 are provided at intervals around the axis of the tank body 10.

[0046] This application provides a drying device for plastic production, comprising a drying tank, a drive assembly mounted on the drying tank, a cage located inside the drying tank and at the output end of the drive assembly, a hot air drying assembly mounted on the drying tank, and a rotation stabilizing assembly positioned between the drying tank and the cage. Plastic granules to be dried can be placed inside the cage. The drive assembly drives the cage to rotate within the drying tank, and the hot air drying assembly delivers hot air into the drying tank to remove surface moisture from the plastic granules. By setting the drive assembly to rotate the cage, and cooperating with the rotation stabilizing assembly to ensure stable cage rotation, the uniformity of drying of the plastic granules is effectively improved, increasing drying efficiency and quality. The hot air drying assembly delivers hot air specifically to effectively remove moisture, and the dried plastic granules can be more easily recycled during rotation within the cage.
