Description

Technical Field

[0001] The invention relates to the technical field of plastic cleaning and recycling equipment, and in particular to a spin-drying dehydrator for granulation. Background Art

[0002] One of the main advantages of recycled plastics is its environmental friendliness. By recycling and reusing waste plastics, recycled plastics reduce dependence on original resources, reduce the impact of plastic waste on the environment, help reduce pollution and protect the environment, and use recycled plastics to help save limited natural resources, especially oil resources, because plastics are usually made from petroleum products. By recycling and reusing, we can reduce the demand for new oil resources. The recycling of plastics needs to be granulated by the granulation production line before use. The dehydrators currently used in the granulation production line are all vertical single dehydration functions without conveying functions. After dehydration, a separate fan is required for conveying. The current production process is that the granulated particles are first dehydrated by the dehydrator, then enter the vibrating screen for screening, and finally sent to the silo by the fan. Since the particles entering the dehydrator are not screened by the vibrating screen, the particle size is uneven, which can easily cause the dehydrator screen hole to be blocked, thereby causing the dehydrator to fail, resulting in a high maintenance frequency of the dehydrator, and the subsequent transportation of the particles after dehydration by the dehydrator also requires a separate conveying fan, which increases the production cost. Therefore, those skilled in the art provide a spin-drying dehydrator for granulation to solve the problems raised in the above background technology. Summary of the invention

DETAILED DESCRIPTION

[0013] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0014] See Figure 1As shown, this specific embodiment adopts the following technical scheme: it includes a frame 1, a bearing seat cover plate 2, a bearing seat 3, a feed hopper 4, a box 5, a rotating shaft 6, a coupling 7, a motor 8, a discharge port 9, an isolation bin 10, a first blade 11, a second blade 12, an arc structure 13 and a gap area 14; the box 5 and the motor 8 are installed on the frame 1, the motor 8 is connected to the rotating shaft 6 through the coupling 7, the motor 8 adopts a 2-stage high-speed motor, both ends of the rotating shaft 6 are installed and connected to the box 5 through spherical roller bearings, the spherical roller bearings are installed in the bearing seat 3 outside the box 5, and the spherical roller bearings and the bearing seat A skeleton oil seal is installed between 3 to play a supporting and sealing dust-proof role. An isolation bin 10 is arranged at one end of the box body 5. A discharge port 9 is arranged at the bottom of the isolation bin 10. The inner wall of the isolation bin 10 is an arc structure 13. The second blade 12 located in the isolation bin 10 on the rotating shaft 6 is perpendicular to the center of the rotating shaft 6, and the second blade 12 is evenly distributed along the circumference of the rotating shaft 6. A gap area 14 is arranged between the arc structure 13 and the second blade 12. The gap directly ensures the linear speed at which the material is finally thrown out. When the material is transported to the second blade 12, it is thrown out of the box body 5 under the action of centrifugal force.

[0015] The first blades 11 located outside the isolation bin 10 are evenly distributed on the rotating shaft 6 in a spiral discontinuous shape. The first blades 11 are used to convey materials and beat and dry materials, so that the materials are guided by the first blades 11 in the box body 5 to perform high-speed rotation and conveying motion; a feed hopper 4 is installed at one end of the box body 5, and the feed hopper 4 is provided with a 45° guide groove to ensure that the material is conveyed forward at a certain angle after entering the box body 5, which is more conducive to the transportation of the material.

[0016] An exhaust hole 17 is provided at the bottom of one side of the box body 5 to maintain the balance of air pressure inside and outside the box body 5, to avoid the formation of pressure difference inside and outside the box body 5 due to the high-speed centrifugal force of the rotating shaft 6, and to prevent the dehydration and transportation of materials from being utilized.

[0017] Large cover plates 15 are fixed on both sides of the box body 5, and the bearing seat 3 is fixed on the large cover plates 15. The large cover plates 15 are detachable to facilitate maintenance of the equipment.

[0018] A cover 16 is fixed on the frame 1, and the box body 5 and the motor 8 are located in the cover 16 to play a protective and dust-proof role.

[0019] The working principle of the present invention is as follows: the bottom of the discharge port 9 is connected to the conveying pipe, and the end of the conveying pipe is connected to the silo. After the material enters the rotating shaft 6 through the feed hopper 4, it is transported to the outlet under the action of the power of the first blade 11. When the material is transported to the outlet, it is thrown out of the box body 5 under the action of centrifugal force. In this process, the gap between the second blade 12 and the arc structure 13 of the isolation bin is used to ensure that the material is thrown out cleanly and at a linear speed. After being thrown out of the box body 5, it enters the conveying pipe and finally enters the silo.

[0020] The present invention changes the production line process: the granulated particles first enter the dehydration vibration screen to remove most of the moisture, and then enter the dehydration type dehydrator of the present invention to remove the remaining moisture, and are thrown into the conveying pipeline under the action of centrifugal force and directly enter the silo, thereby reducing the air conveying link.

[0021] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected.
