Flame retardant drying equipment is a highly efficient, energy-saving, and automated drying device that can meet the drying needs of various materials and is widely used in various industries.

[0003] Common flame retardant drying devices typically lack anti-sticking devices, allowing the flame retardant to adhere to the inner wall of the drying equipment during the drying process. This not only leads to internal contamination but also affects the quality and purity of the flame retardant. Furthermore, the adhesion reduces the usable space within the drying chamber, hindering the uniform distribution of airflow and thus reducing drying efficiency. Additionally, the flame retardant adhering to the inner wall may re-wet, resulting in incomplete drying and causing adverse effects on the user experience.

[0020] Combined with appendix Figure 1-3 This embodiment proposes a three-dimensional thermal cycle flame retardant drying device, including an oven 1. A control frame 2 is detachably provided on the top of the oven 1. A lifting frame 3 is provided on one side of the control frame 2. The lifting frame 3 is located inside the oven 1. The circumferential contour of the lifting frame 3 is consistent with the circumferential contour of the inner wall of the oven 1. At least one lifting mechanism is provided on the control frame 2. The lifting mechanism is connected to the lifting frame 3 so that the lifting frame 3 can move up and down inside the oven 1.

[0021] In this embodiment of the three-dimensional thermal cycle flame retardant drying device, the control frame 2 is generally detachably connected to the drying oven 1 via bolts or other fasteners. The drying oven 1 serves as a container for storing the flame retardant, which is then dried within it. The drying oven 1 is typically equipped with a feed pipe, and a discharge hopper can be installed at its bottom. The flame retardant can be fed and discharged through the feed pipe and discharge hopper, or added to the drying oven 1 after the control frame 2 is disassembled. Optionally, a stirring mechanism can be installed at the bottom of the drying oven 1 to agitate the flame retardant during the drying process, thereby improving drying efficiency.

[0022] The three-dimensional thermal circulation flame retardant drying device in this embodiment mainly relies on the lifting motion of the lifting frame 3 to clean the flame retardant adhering to the inner wall of the drying oven 1. The specific working principle is as follows: the lifting mechanism drives the control frame 2 to move up and down, and the circumferential contour of the lifting frame 3 is consistent with the circumferential contour of the inner wall of the drying oven 1, so that when the lifting frame 3 moves downward, the circumferential edge of the lifting frame 3 can scrape off the flame retardant adhering to the inner wall of the drying oven 1.

[0023] Preferably, a scraper 7 is provided at the circumferential edge of the lifting frame 3, and the scraper 7 is interference-fitted with the inner wall of the oven 1. The scraper 7 can be made of hard rubber or plastic material, and it is generally necessary to ensure that the hardness of the scraper 7 is less than the hardness of the inner wall of the oven 1, so as to avoid damaging or scratching the inner wall of the oven 1.

[0024] The lifting mechanism can be an electric actuator, a pneumatic cylinder, or a hydraulic cylinder, etc. In this embodiment, the lifting mechanism includes a drive unit 40, a driving gear 41, a driven gear 42, and at least one lifting rod 43. The drive unit 40 is fixedly mounted on the control frame 2, which includes a cavity 20. The driving gear 41 and the driven gear 42 are located inside the cavity 20. The output end of the drive unit 40 is fixedly connected to the driving gear 41, and the driving gear 41 meshes with the driven gear 42. The lifting rod 43 passes through the control frame 2 and the corresponding driven gear 42. The driven gear 42 is provided with an internal thread, and the lifting rod 43 is provided with an external thread. The internal thread meshes with the external thread, and the end of the lifting rod 43 is rotatably connected to the lifting frame 3.

[0025] In a further preferred embodiment, the drive unit 40 is located in the middle of the control frame 2, and two lifting rods 43 are provided and symmetrically arranged on both sides of the drive unit 40, with the ends of the two lifting rods 43 being rotatably connected to the lifting frame 3.

[0026] The drive unit 40 is generally a motor, which drives the drive gear 41 to rotate, which in turn drives the driven gear 42 to rotate. The internal thread of the driven gear 42 meshes with the external thread of the lifting rod 43, and the lifting rod 43 is rotatably connected to the lifting frame 3, so that the lifting rod 43 drives the lifting frame 3 to descend synchronously during its rotation. The circumferential rotation of the lifting rod 43 does not drive the circumferential rotation of the lifting frame 3 because, on the one hand, the circumferential contours of the oven 1 and the lifting frame 3 can mutually limit each other, and on the other hand, the symmetrical lifting rods 43 can mutually constrain the circumferential rotation of the lifting frame 3.

[0027] A bearing 5 is preferably provided between the end of the lifting rod 43 and the lifting frame 3. The bearing 5 makes the relative rotation between the end of the lifting rod 43 and the lifting frame 3 smoother and more stable.

[0028] Based on the aforementioned working principle of the oven 1, it is known that a stirring mechanism is provided at the bottom of the oven 1, and the lowest position of the lifting frame 3 needs to avoid interference with the stirring mechanism. To limit the descent stroke of the lifting rod 43, in a preferred embodiment, a limiting plate 44 is fixedly provided at the end of the lifting rod 43 away from the lifting frame 3. When the lifting rod 43 descends to the lowest position, the limiting plate 44 will abut against the upper surface of the control frame 2, thereby preventing the lifting rod 43 from continuing to descend.

[0029] Since the lifting frame 3 is the main moving component, it needs to have high rigidity and strength. Therefore, in the preferred embodiment, a reinforcing plate 30 is fixedly installed on the lifting frame 3, and the end of the lifting rod 43 is rotatably connected to the reinforcing plate 30. That is, the overall rigidity of the lifting frame 3 is enhanced by the reinforcing plate 30, and the end of the lifting rod 43 is directly connected to the reinforcing plate 30, making the reinforcing plate 30 the main carrier for transmitting push and pull forces, thereby improving its service life.

[0030] In other embodiments, a dustproof and heat dissipation mesh 6 is provided on the control frame 2, which connects the cavity 20 to the external space. The dustproof and heat dissipation mesh 6 allows the heat generated by the movement of the mechanism inside the cavity 20 to be dissipated, while also serving a dustproof function to prevent dust in the environment from affecting the transmission of the mechanism.

[0031] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
