[0002] Plastic particles or powders and other materials need to be dried at a specific temperature for a certain period of time to discharge the moisture inside the material and meet the requirements of the production process. After the material is dried, the material is automatically transported to the molding machine for production. After the dryer replaces the drying material, when it is turned on for the first time, or when the molding machine stops production, it is easy to cause the material to agglomerate, making it impossible to transport and use the material. If the material agglomerates severely, it may even cause equipment damage. Utility Model Content

The controller is connected to the self-circulating valve so that the controller controls the material box to convey materials to the first conveying hopper at intervals through the self-circulating valve and controls the opening and closing of the self-circulating pipeline.
[0005] Preferably, the drying system comprises a molding machine and a second conveying hopper, wherein the second conveying hopper is arranged on the top of the molding machine, and the bottom of the drying cylinder is connected to the second conveying hopper.

BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a schematic structural diagram of the anti-caking drying system of the utility model. DETAILED DESCRIPTION
[0011] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments.
[0012] like Figure 1The figure shows a specific embodiment of an anti-caking drying system provided by the utility model. The drying system comprises a drying cylinder 1, a first conveying hopper 2, a material box 4, a self-circulating valve 3, and a controller. The first conveying hopper 2 is arranged at the top of the drying cylinder 1 to convey materials to the drying cylinder 1. The first end of the self-circulating valve 3 is connected to the material box 4, the second end of the self-circulating valve 3 is connected to the first conveying hopper 2, and the third end of the self-circulating valve 3 is connected to the bottom of the drying cylinder 1. The pipelines between the first conveying hopper 2, the drying cylinder 1 and the self-circulating valve 3 form a self-circulating pipeline. A heating mechanism is arranged in the drying cylinder 1. The controller is connected to the heating mechanism so that the controller controls the heating temperature of the drying cylinder 1 by the heating mechanism. Specifically, the controller is used to control the drying cylinder to have a first heating temperature and a second heating temperature, and the first heating temperature is less than the second heating temperature.
[0013] The system of the utility model controls the drying temperature of the drying cylinder, especially when the machine is started for the first time, the controller can first heat up to a lower temperature according to the preset material characteristics, and then heat up to the material-specific drying temperature after the internal temperature of the drying cylinder is stable, so as to prevent the surface of the material from being dried quickly at a high temperature when the internal humidity of the material is high, which may easily cause the material to stick together and agglomerate, and at the same time reduce the drying time of the material in a high temperature state.
[0014] The controller is connected to the self-circulation valve 3, so that the controller controls the material box 4 to convey materials to the first conveying hopper 2 at intervals through the self-circulation valve 3 and controls the opening and closing of the self-circulation pipeline.
[0015] The system of the utility model conveys materials into the drying drum at intervals, especially when the machine is started for the first time, and can convey materials into the drying drum within the interval time according to the preset material characteristics, so as to ensure that the materials in the drying drum are controlled within a reasonable material level range during the initial drying. After the initial material level is reached, the material conveying is stopped to prevent the materials at the bottom of the drying drum from sticking and agglomerating due to excessive pressure.
[0016] As for the opening time of the self-circulation pipeline, you can choose to open the self-circulation pipeline when the molding machine is under maintenance or production is stopped. At this time, there is no need to convey materials to the molding machine. After the set time is reached, the material will self-circulate, and the material will be circulated from the bottom of the drying cylinder to the upper part. The material conveying flow prevents the dried material from sticking together. You can also choose to open the self-circulation pipeline after the material in the drying cylinder reaches the initial material level, so that the material will self-circulate, and the material will be circulated from the bottom of the drying cylinder to the upper part. The material conveying flow prevents the material from sticking together. At the same time, the material replacement flow at the bottom and upper part of the drying cylinder ensures that the material at the bottom of the drying cylinder can also be fully dried and the moisture can be discharged.
[0017] like Figure 1 As shown, the drying system includes a molding machine 10 and a second conveying hopper 11 . The second conveying hopper 11 is arranged on the top of the molding machine 10 , and the bottom of the drying cylinder 1 is connected to the second conveying hopper 11 .
[0018] like Figure 1 As shown, the drying system includes a conveying fan 13 , and the conveying fan 13 is connected to the first conveying hopper 2 through a first conveying valve 14 , and the conveying fan 13 is connected to the second conveying hopper 11 through a second conveying valve 12 .
[0019] like Figure 1 As shown, the drying system includes a drying heater 5, a dehumidifying cylinder 6, a regeneration heater 7, a regeneration fan 9, and a drying fan 8. The exhaust port of the drying cylinder 1 is connected to the air inlet end of the drying fan 8, the air outlet end of the drying fan 8 is connected to the dehumidifying cylinder 6, the air outlet end of the regeneration fan 9 is connected to the dehumidifying cylinder 6 through the regeneration heater 7, and the dehumidifying cylinder 6 is connected to the air inlet of the drying cylinder 1 through the drying heater 5.
[0020] The beneficial effect of the anti-caking drying system of the utility model is that the controller is connected to the heating mechanism of the drying cylinder to control the heating temperature of the drying cylinder, thereby preventing the material from sticking and agglomerating due to rapid high-temperature drying of the surface when the internal humidity of the material is relatively high when the machine is first started, and at the same time reducing the drying time of the material in a high-temperature state; the controller is connected to the self-circulation valve to control the material box to convey the material to the conveying hopper of the drying cylinder at intervals, thereby ensuring that the material of the drying cylinder is controlled within a reasonable material level range during the initial drying, thereby preventing the material at the bottom of the drying cylinder from sticking and agglomerating due to excessive pressure; a self-circulation pipeline is formed by the self-circulation valve, and the material is circulated and conveyed from the bottom of the drying cylinder to the top, and the material conveying flow is used to prevent the material from sticking and agglomerating, and at the same time, the material at the bottom and upper part of the drying cylinder are replaced by the flow, thereby ensuring that the material at the bottom of the drying cylinder can also be fully dried and the moisture can be discharged.
[0021] In this specification, the utility model has been described with reference to its specific embodiments. However, it is obvious that various modifications and changes can be made without departing from the spirit and scope of the utility model. Therefore, the description and drawings should be regarded as illustrative rather than restrictive.
