Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic particle dewatering, in particular to centrifugal plastic particle drying equipment. Background Art
[0002] In the production process of plastic particles, it is necessary to first obtain plastic strips through an extruder, and then the plastic strips are cooled and solidified in a water tank before being cut to obtain plastic particles. Therefore, the surface of the plastic particles contains a lot of moisture and needs to be dehydrated and dried.
[0003] Plastic pellets can be dehydrated using a spin dryer. After the plastic pellets are poured into the spin dryer, they are dried by the rotating drum. The dried plastic pellets are then removed. This operation is cumbersome and cannot be performed online. Furthermore, excessive amounts of plastic pellets added each time can easily cause accumulation, affecting the drying effect. To achieve automatic loading and unloading of plastic pellets during the drying process, additional loading and unloading equipment is often required, which is costly and energy-intensive, and requires improvement.

[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1~Figure 2 , the embodiments of the present utility model include:
[0021] like Figure 1 The centrifugal plastic particle drying equipment shown is used for online drying of plastic particles, and comprises: a shell 1, a rotating drum 2 and a particle layering assembly 5. A fixing seat 13 is provided at the bottom of the shell 1, which can be fixed by screws, and has a firm structure.
[0022] The drum 2 is vertically arranged in the shell 1. In this embodiment, a slewing bearing 7 located at the bottom of the drum 2 is provided on the fixed seat 13. The slewing bearing 7 supports the drum 2 during rotation, ensuring the smooth rotation of the drum 2. A downwardly extending cylinder 14 is concentrically arranged at the bottom of the drum 2. A gear ring 11 is concentrically arranged on the outer circle of the cylinder 14. The gear ring 11 is welded to the outer circle of the cylinder 14 and has good synchronization. A motor 9 is provided on the fixed seat 13. A gear 8 meshing with the gear ring 11 is provided on the motor 9 to realize the rotational drive of the cylinder 14 and drive the rotation of the drum 2. The motor 9 can be controlled by a PLC to intermittently change the speed to achieve fast and slow changes in the speed, thereby avoiding overheating problems caused by continuous high-speed operation of the motor 9.
[0023] The particle layering assembly 5 is arranged in the drum 2, as shown in FIG. Figure 2 As shown, the particle layering assembly 5 includes multiple guide members 51 spaced apart vertically. A connecting rod 52 is provided between two adjacent guide members 51. The ends of the connecting rod 52 are welded to the corresponding layering assembly to achieve the upper and lower spacing of the guide members. A lifting ring 54 is provided on the top of the top guide member to facilitate lifting and easy operation.
[0024] like Figure 1 As shown, a cover plate 3 is provided on the top of the housing 1, and a first hopper 4 is provided on the cover plate 3. The cut plastic particles flow downward into the drum 2 through the first hopper 4. The cover plate 3 is fixed with screws and is easy to disassemble. The cover plate 3 is removed to maintain the drum 2 and the particle stratification assembly 5.
[0025] like Figure 2 As shown, the guide member 51 includes a first conical cover 511 and a second conical cover 512 symmetrically connected up and down, the opening of the first conical cover 511 points downward, and the opening of the corresponding second conical cover 512 points upward, and welding is performed to obtain a hollow guide member 51.
[0026] After passing through first hopper 4 and downward into drum 2, the plastic particles are guided by first conical cover 511, the topmost guide member. This guide guide causes the plastic particles to slide down the surface of first conical cover 511 and disperse around it. As drum 2 rotates at high speed, centrifugal force is used to remove moisture, achieving the first drying step. The bottom edge diameter of first conical cover 511 corresponds to the inner diameter of drum 2, providing a tight fit and preventing plastic particles from becoming lodged in the gap between the bottom edge of first conical cover 511 and the inner wall of drum 2.
[0027] In this embodiment, first drop holes 513 are arranged at intervals on the edge of the first conical cover 511. The diameter of the first drop holes 513 is not large, which can allow the plastic particles to fall and ensure that some plastic particles are retained on the first conical cover 511. The plastic particles retained on the first conical cover are dispersed under the impact of the newly entered plastic particles, and then gradually fall through the first drop holes 513.
[0028] A second drop hole 514 is provided at the bottom of the second conical cover 512, and a drop pipe 53 extending into the barrel 14 is provided at the bottom of the lowest guide member. During the high-speed rotation of the drum 2, the plastic particles adhere to the inner wall of the drum 2 under the action of centrifugal force and do not fall. The speed of the motor is intermittently adjusted, first reducing the speed of the drum 2 so that the plastic particles on the inner wall of the drum 2 fall due to gravity and enter the second conical cover through the first drop hole. Then, they fall through the second drop hole to the first conical cover of the lower guide member for redispersion, increasing the speed of the drum 2 for a second spin-drying. Similarly, after multiple spin-dryings, the plastic particles fall along the drop pipe into the second hopper, realizing automatic unloading and online spin-drying. In this application, three guide members 51 are used, which can perform three spin-drying of the plastic particles, improving the spin-drying effect.
[0029] like Figure 1 As shown, a second hopper 10 is mounted on a fixed base 13, located below a cylindrical body 14. A downwardly extending discharge pipe 12 is provided at the bottom of the second hopper 10, enabling automatic discharge of the plastic particles after they have been spun dry. An annular water trough 6 is provided on the inner wall of the housing 1, located below the edge of the rotating drum 2. A drain pipe 15 is provided at the bottom of the annular water trough 6. During the rotation of the rotating drum 2, water is ejected through the filter holes on the drum 2, flows downward along the inner wall of the drum 2 into the annular water trough 6, and is ultimately discharged through the drain pipe 15, thus preventing water accumulation.
[0030] In summary, the centrifugal plastic particle drying equipment pointed out in the utility model can perform online drying and automatic unloading of plastic particles, thereby improving production efficiency. Moreover, the plastic particles have good dispersion in the equipment, and multiple drying processes improve the drying effect.
