Description

Technical Field

[0001] This invention relates to the field of material loading and unloading, and in particular to an automatic loading and unloading device for a rotary double cone dryer. Background Technology

[0002] In the preparation of granular materials, a drying process is usually involved, and a rotary double cone dryer is a commonly used piece of equipment. Its main function is to accelerate the drying process by introducing a heat source through a heating layer under vacuum, utilizing the contact between the inner wall of the dryer and the wet material, and by rotating the dryer to agitate the material. This equipment is widely used in the drying of granular materials. In some industrial production lines, such as in the preparation of granular materials, it is necessary to transfer materials from one unit to a rotary double cone dryer for drying, and then transfer the dried materials to another unit. However, many production lines still rely on manual handling for material feeding and discharging. This method has the following drawbacks: when the material volume is large or heavy, a large amount of manpower is required, leading to reduced production efficiency; manual operation makes it difficult to achieve assembly line production, limiting the continuity and efficiency of production; and when production demand increases, the existing manual operation methods cannot meet the higher production requirements.

[0024] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1 to 5 As shown, the present invention provides an automatic loading and unloading device for a rotary double cone dryer, the device comprising a vacuum suction mechanism, a rotary double cone dryer docking mechanism, and a loading mechanism 9.

[0026] The vacuum conveying mechanism includes a feed pipe frame 1, a feed pipe 2, a vacuum feeder 3, a dust collection bin 4, a cyclone separator 5, and a column support. The feed pipe 2 is secured to the feed pipe frame 1 with stainless steel clamps and nuts. The feed pipe 2 connects to the inlet of the cyclone separator 5, and the cyclone separator 5 is connected to the vacuum feeder 3 by a PVC steel wire flexible hose 6. The vacuum feeder 3 is a vacuum conveyor that uses a vacuum generator as a vacuum source. The vacuum feeder 3 and the cyclone separator 5 are mounted on opposite sides of the column support via flanges, bolts, and screws. The dust collection bin 4 is integrated with the vacuum feeder 3 and is located below the vacuum feeder 3.

[0027] like Figure 2 As shown, the cyclone separator 5 includes a dust outlet 30, a tangential feed inlet 10, a filter screen 11, and a particle outlet 12. The cyclone separator 5 has a conical structure. The particle outlet 12 is located at the bottom of the cyclone separator 5 and is connected to the feeding docking mechanism 7 via a flexible hose. The tangential feed inlet 10 is located on the side wall of the cyclone separator 5 and is connected to the feed pipe 2. The dust outlet 30 is located at the top of the cyclone separator 5 and is equipped with a filter screen 11. The dust outlet 30 is connected to the vacuum feeder 3 via a flexible hose.

[0028] The rotary double cone dryer docking mechanism includes a feeding docking mechanism 7 and a positioning mechanism 8. The feeding docking mechanism 7 is connected to the cyclone separator 5 by a transparent flexible hose. The feeding docking mechanism 7 and the positioning mechanism 8 are mounted on the column support by bolts and screws; the positioning mechanism 8 is installed on the lower right side of the feeding docking mechanism 7.

[0029] like Figure 3As shown, the feeding docking mechanism 7 includes a mounting base A13, a docking guide rail fixing plate 14, a cylinder A15, a docking driving plate 16, and a sealing interface. The mounting base A13 is mounted on the support column and connected to the docking guide rail fixing plate 14. The lower end of the docking guide rail fixing plate 14 is provided with a guide rail and the cylinder A15. The docking driving plate 16 is mounted on the guide rail and is driven by the cylinder A15 to move on the guide rail. The docking driving plate 16 is provided with a sealing interface, which is connected to the particle outlet 12 of the cyclone separator 5 through a hose. The sealing interface is used to dock with the feed inlet of the rotary double cone dryer. A disc spring 17 and a sealing washer are provided at the sealing interface. The sealing washer is used to seal the interface and the feed inlet of the rotary double cone dryer, and the disc spring 17 is used to dock with the feed inlet of the rotary double cone dryer.

[0030] like Figure 4 As shown, the positioning mechanism 8 includes a guide shaft 18, a guide insert 19, a floating joint 20, a cylinder B21, a buffer block 22, a mounting plate 23, and a mounting base B24. The mounting base B24 is mounted on the support column, and the mounting plate 23 is connected to the mounting base B24. The cylinder B21 and the guide shaft 18 are mounted on the mounting plate 23. The piston of the cylinder B21 is connected to the floating joint 20, and the floating joint 20 is connected to the guide insert 19. The floating joint 20 is set on the guide shaft 18. The cylinder B21 drives the floating joint 20 to move the guide insert 19 along the guide shaft 18. A buffer block 22 is set at the end of the guide insert 19.

[0031] like Figure 5 As shown, the feeding mechanism 9 includes a receiving port, a lifting cylinder, a feeding hose, and a mounting bracket. The mounting bracket is fixed to the ground, and the lifting cylinder is mounted on the mounting bracket. The upper end of the lifting cylinder has a receiving port for connecting to the rotary double cone dryer. The bottom of the receiving port is connected to the feeding hose. The receiving port moves up and down under the drive of the lifting cylinder. The feeding mechanism 9 is equipped with a position sensor for measuring the displacement of the receiving port.

[0032] This invention proposes an automatic loading and unloading device for a rotary double cone dryer. The main implementation methods of this device are as follows:

[0033] After receiving the signal to start feeding, the rotary double cone dryer stops rotating. At this time, the feed inlet of the rotary double cone dryer's hopper stops at the position of the feeding docking mechanism 7. The feeding docking mechanism 7 docks with the feed inlet of the rotary double cone dryer, forming a closed channel between the feeding docking mechanism 7 and the rotary double cone dryer.

[0034] To improve positioning accuracy, the automatic loading and unloading device is designed with a positioning mechanism 8. Positioning mechanism 8 uses a cylinder-guided positioning method to perform secondary precise positioning of the material hopper of the rotary double cone dryer. The guide insert 19 rotates the material hopper to its docking position with the loading docking mechanism 7. Simultaneously, the disc spring 17 and sealing gasket design of the sealing interface of the loading docking mechanism 7 ensure reliable docking even with a certain degree of error, guaranteeing docking accuracy and achieving point-to-point docking. The sealing gasket also ensures the sealing of the interface, preventing material leakage.

[0035] After the sealed interface forms a closed channel with the rotary double cone dryer's hopper, feed pipe 2 begins feeding, and then the rotary double cone dryer begins drying. During the feeding process, the airflow generated by the vacuum generator inside the vacuum feeder 3 causes the material to enter the feed pipe 2 from the starting end and be sucked into the cyclone separator 5 tangentially from the feed inlet 10. Since the material cannot pass through the filter screen 11 in the cyclone separator 5, it falls into the rotary double cone dryer through the outlet of the cyclone separator 5. Dust passes through the filter screen 11, passes through the cyclone separator 5, enters the vacuum feeder 3, and is finally collected in the dust collection bin 4.

[0036] After the rotary double cone dryer completes its operation, the dryer stops rotating upon detection by the positioning sensor on the feeding mechanism 9. At this point, the feed inlet is rotated to the position where it aligns with the feeding mechanism 9. The lifting cylinder then raises the receiving port to dock with the rotary double cone dryer, achieving a fixed-point docking. The material is then transferred to the next device through the receiving port.

[0037] In practical use, in order to produce materials in large quantities, three rotary double cone dryers are used as a module. Through program control, the module can be connected, fed and unloaded at the same time. This not only reduces the number of operators but also improves production efficiency.

[0038] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
