Description

Technical Field

[0001] The utility model relates to the technical field of natural rubber processing, in particular to a natural rubber latex multi-layer filtering screen device. Background Art

[0002] Natural rubber emulsion, also known as natural latex, is an emulsion provided by rubber trees. It is an emulsion of rubber particles in a near-neutral medium. Natural rubber latex filtration mainly uses screens and fine pores to filter the emulsion to remove impurities and particulate matter. When the emulsion flows through the screen tube or screen, large particles and impurities will be intercepted on the screen, while the pure emulsion will flow out through the screen.

[0003] A search of the publication number CN216914495U discloses a natural rubber latex multi-layer filter screen device, including a device body, characterized in that: a filter screen mechanism is provided at the outer left end of the device body, and a sliding mechanism is provided at the inner left upper end of the device body. In the utility model, the first filtration is performed through the first layer of screen, the second filtration is performed through the second layer of screen, and the third filtration is performed through the third layer of screen. Then, the stirring rod blades are driven to rotate by a motor, and the stirring rod blades are provided between the second layer of screen and the third layer of screen. The stirring is uniformly stirred in the last step and then filtered. The application has the following deficiencies: the natural rubber latex is filtered through the first layer of screen, the second layer of screen and the third layer of screen. When filtering, the filtration speed is the flow speed of the natural rubber latex, which takes a long time. Therefore, a natural rubber latex multi-layer filter screen device is proposed.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-4 The utility model provides a technical solution for a natural rubber latex multi-layer filter screen device, including a device housing 1 and a feed hopper 2. The feed hopper 2 is installed on the top of the device housing 1, and the natural rubber latex is poured into the interior of the device housing 1 through the feed hopper. A drive motor 4 is installed on one side of the device housing 1, and a device door 3 is hinged on the front of the device housing 1.

[0022] like Figure 2 and Figure 4As shown, a fixed frame 8 is symmetrically installed on the inner wall of the device housing 1, and a transmission rod 9 is rotatably connected between the two fixed frames 8. A semicircular gear 18 is installed on the two transmission rods 9, and a connecting rod 13 is installed inside the two fixed frames 8. A strip plate 14 is slidably connected to the two connecting rods 13. A connecting strip 15 is installed on the top of the strip plate 14, and a tooth block 19 adapted to the semicircular gear 18 is provided at the bottom of the strip plate 14. A first spring 16 is sleeved on the two connecting rods 13, and a baffle 17 is installed on the connecting rod 13. The baffle 17 limits the strip plate 14 to prevent the elastic force of the first spring 16 from separating the strip plate 14 from the connecting rod 13. One side of the baffle 17 abuts against one end of the strip plate 14, and one end of the first spring 16 abuts against the other end of the strip plate 14. The tooth block 19 meshes with the semicircular gear 18. The power output end of the driving motor 4 is fixedly connected to one end of the transmission rod 9. The top ends of the two fixed frames 8 are provided with sliding grooves adapted to the connecting strips 15. The top ends of the two connecting strips 15 extend to the outside of the top of the fixed frame 8. The placement frames 6 are installed on the two connecting strips 15. The driving motor 4 drives the transmission rod 9 to rotate. As the transmission rod 9 rotates, the two semicircular gears 18 rotate together. The semicircular gears 18 engage with the tooth block 19, driving the strip plate 14 to slide on the connecting rod 13. When the strip plate 14 slides, it squeezes the first spring 16 and drives the placement frame 6 to move together. After the semicircular gear 18 rotates, it does not engage with the tooth block 19. The elastic force of the first spring 16 causes the strip plate 14 to reset and slide on the connecting rod 13, thereby driving the placement frame 6 to move back and forth, sliding the screening frame 7, and accelerating the flow filtration of the natural rubber latex.

[0023] like Figure 3 and Figure 5 As shown, a drawer box 5 is slidably provided near the bottom position of the device housing 1, three screening frames 7 are provided on the placement frame 6, and the three screening frames 7 are all installed with filter screens 10. The filter holes of the three filter screens 10 have different sizes. Slide bars 11 are symmetrically installed on the three screening frames 7, and chute grooves adapted to the slide bars 11 are symmetrically provided on the placement frame 6. Limit rods 12 are symmetrically provided on the three screening frames 7, and each chute is provided with a jack adapted to the limit rod 12. It is said that a circular groove is provided, and a second spring 20 is installed in each circular groove. One end of each limit rod 12 extends into the circular groove, and a connecting piece 21 is installed at one end of the limit rod 12. A push rod 22 is installed on the connecting piece 21. The end of the connecting piece 21 away from the limit rod 12 is in contact with the second spring 20, pushing the push rod 22, driving the limit rod 12 to move toward the inside of the screening frame 7, so that the limit rod 12 is withdrawn from the jack, the screening frame 7 is removed from the placement frame 6, and the filter screen 10 is cleaned.

[0024] The working principle of the utility model is as follows: natural rubber latex is poured into the interior of the device housing 1 through the feed hopper 2 and falls on the filter screen 10 of the screening frame 7. The driving motor 4 is operated, driving the transmission rod 9 to rotate. The transmission rod 9 rotates and the two semicircular gears 18 rotate together. The semicircular gears 18 are engaged with the tooth block 19, driving the strip plate 14 to slide on the connecting rod 13. When the strip plate 14 slides, it squeezes the first spring 16 and drives the placement frame 6 to move together. After the semicircular gear 18 rotates, it does not mesh with the tooth block 19. Through the first spring 16 The elastic force causes the strip plate 14 to reset and slide on the connecting rod 13, thereby driving the placement frame 6 to move back and forth, sliding the screening frame 7, accelerating the flow and filtration of the natural rubber latex, and the filtered natural rubber latex flows into the drawer box 5 for storage. The natural rubber latex can be taken out by pulling out the drawer box 5, pushing the push rod 22 to drive the limit rod 12 to move toward the inside of the screening frame 7, and the connecting piece 21 squeezes the second spring 20 to make the limit rod 12 withdraw from the jack, remove the screening frame 7 from the placement frame 6, and clean the filter screen 10.
