[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.
[0023] See also Figure 1-5 A masterbatch screening device includes a housing 1, the inner cavity of which is mounted a vertical fixed cylinder 6. Slides 8 are fixedly mounted at each end of the inner cavity of the fixed cylinder 6, and a square tube 7 is slidably mounted on the two slides 8. A power mechanism is mounted on the top of the housing 1 to drive the square tube 7 up and down. Several side extension rods of the square tube 7 are fixedly connected to a spiral screen 2, and a feeding hopper 13 is mounted on the top of the housing 1, leading to the top of the spiral screen 2. The bottom of the spiral screen 2 has uniform sieve holes. The bottom opening of the feeding hopper 13 leads to the top of the spiral screen 2. A spiral collection channel 3 is fixedly wound around the outer surface of the fixed cylinder 6, which fits the spiral screen 2 from top to bottom. The spiral collection channel 3 collects impurities screened by the spiral screen 2. A heating plate 12 is installed at the bottom opening of the housing 1 to heat the air drawn into the housing 1. A spiral air guide plate 4 is fixedly mounted on the inner cavity of the housing 1, and the spiral air guide plate 4 guides the rising air between the spiral screen 2 and the spiral collection channel 3. The hot air in the housing 1 spirals upward under the guidance of the spiral air guide plate 4. As the hot air rises, it continuously flows into the gap between the spiral sieve 2 and the spiral collecting duct 3, and rises through the sieve holes of the spiral sieve 2 to dry the masterbatch in the spiral sieve 2. An exhaust mechanism is installed on the top of the housing 1.
[0024] The power mechanism includes a drive motor 11 fixedly mounted on the top of the housing 1. The output end of the drive motor 11 is coaxially fixedly connected to a drive disc 10. The eccentric column of the drive disc 10 is rotatably connected to a connecting rod 9, which is also rotatably connected to the top of the square tube 7. The drive motor 11 rotates the drive disc 10, which, through the connecting rod 9, drives the square tube 7 up and down. This causes the spiral sieve 2 to vibrate up and down, screening the masterbatch, and the masterbatch in the spiral sieve 2 flows from top to bottom.
[0025] The exhaust mechanism includes an exhaust pipe 14 connected to the top of the housing 1. A fan 15 is installed at the bottom of the vertical tube of the exhaust pipe 14. A one-way vent assembly is installed in the horizontal tube leading from the exhaust pipe 14 to the housing 1, which is only used to exhaust the interior of the housing 1. Fan 15 is a high-speed fan. Fan 15 blows air at high speed from the bottom to the top of the vertical tube of the exhaust pipe 14. At the same time, the high-speed airflow in the vertical tube draws out the air in the horizontal tube and then draws out the air in the housing 1 through the one-way vent assembly.
[0026] The one-way ventilation group includes: a fixed ring 16 fixedly installed in the horizontal tube of the exhaust pipe 14. A movable plug 17 is inserted into the side of the fixed ring 16 away from the shell 1. The part of the movable plug 17 inserted into the fixed ring 16 is conical, and the through hole of the fixed ring 16 is adapted to the movable plug 17. At least two springs 18 are connected between the fixed ring 16 and the movable plug 17, and each spring 18 is in a stretched state. When the horizontal tube of the exhaust pipe 14 extracts air from the shell 1, the movable plug 17 separates from the fixed ring 16, and the air flow passes through the gap between the movable plug 17 and the fixed ring 16; when the exhaust stops, under the elastic force of the spring 18, the movable plug 17 and the fixed ring 16 are plugged together.
[0027] Several side extension rods of the square tube 7 pass through the fixed cylinder 6 and are fixedly connected to the spiral screen path 2. The fixed cylinder 6 is provided with through grooves adapted to the up and down movement of the side extension rods, so that the square tube 7 and the spiral screen path 2 can vibrate up and down together.
[0028] The bottom outlets of both the spiral sieve track 2 and the spiral collection track 3 are connected to a collection hopper 5, which extends out of the inner cavity of the housing 1. During screening, the spiral sieve track 2 transmits some of its vibrations to the spiral collection track 3, causing impurities in the spiral collection track 3 to flow downward into the collection hopper 5. The collection hopper 5 is used to collect objects flowing out of the bottom of the spiral sieve track 2 and the spiral collection track 3.
[0029] Working principle:
[0030] During operation, the fan 15 blows air at high speed from the bottom to the top of the vertical tube of the exhaust pipe 14. The high-speed airflow in the vertical tube draws out the air in the horizontal tube and draws out the air in the shell 1 through the one-way ventilation component. At the same time, the air inhaled from the bottom of the shell 1 is heated by the heating disk 12 to become hot air. Then the driving motor 11 drives the driving disk 10 to rotate. The rotating driving disk 10 drives the square tube 7 together with the spiral screen 2 to vibrate up and down through the connecting rod 9. Then, the masterbatch is poured into the feeding hopper 13, and the masterbatch flows to the spiral screen 2. Under the vibration screening of the spiral screen 2, the impurities fall into the spiral collecting channel 3. Finally, the masterbatch and impurities flow out of the shell 1 through the two collecting hoppers 5 respectively.
[0031] When hot air dries the masterbatch, the hot air in the shell 1 spirally rises under the guidance of the spiral air guide plate 4, and while rising, the hot air continuously flows to the gap between the spiral sieve channel 2 and the spiral collecting channel 3, and rises through the sieve holes of the spiral sieve channel 2 to dry the masterbatch in the spiral sieve channel 2.
[0032] It should be noted that the above content only illustrates the technical idea of the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, they can make several improvements and modifications without departing from the principles of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
