Description

Technical Field

[0001] The utility model relates to the technical field of material screening, in particular to an anti-eccentric load circular swing double screening frame with evenly distributed feeding materials. Background Art

[0002] In the process of industrial production and material handling, screening is a key link. Among them, the artificial imitation design principle of the swing screen is a high-efficiency screening machine specially designed to meet the needs of large-scale and high-precision screening. The existing circular swing screen is driven by an exciter to swing, so that the material moves on the screen in the same way as manual screening, thereby achieving the screening effect. As the material moves in the screen frame, it passes through the material port and falls into the screen. Driven by the vibrator, the material is screened by the screen, and the larger particles are transported to the outlet to achieve the screening effect.

[0003] When the existing screening frame and screen receive the feeding, the material tends to concentrate in a certain area and cannot be evenly distributed on the screening frame, which easily leads to excessive accumulation of material in some areas and sparse material in other areas. This not only affects the screening effect, but also due to uneven feeding and the movement characteristics of the material during the screening process, it is easy to cause overloading, which makes the equipment as a whole overloaded, thereby reducing the stability and service life of the equipment.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe 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 the embodiments. 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.

[0038] See also Figure 1-6 The utility model provides a technical solution: a circular swing double screening frame with uniform feeding and anti-biased loading, comprising a screen frame 1, a screen mesh 2, a delivery pipe 3, a screen frame 4, a screen mesh 5, a delivery pipe 6, a positioning pipe 7, a positioning nut 8, a spiral material distribution frame 9, a convergence ring 10, a positioning ring frame 11, a tapered guide column 12, a material distribution plate 13, and a limiting and concentrated bucket 14;

[0039] Among them, the screen frame 1 is set as a ring frame structure, the inner wall of the screen frame 1 is installed with a screen 2, and the upper end of the screen frame 1 is installed with a screen frame 2 4, and the inner wall of the screen frame 2 4 is installed with a screen 2 5. The screen frame 1, the screen 2, the screen frame 2 4 and the screen 2 5 constitute a double-layer double circular swing screening frame main structure;

[0040] A hole is opened on one side of the screen frame 1, and the hole of the screen frame 1 is installed with the delivery pipe 3. The delivery pipe 3 is set as an L-shaped pipe structure, and the bottom of the delivery pipe 3 passes through one end of the screen frame 1 and is flush with the surface of the screen 2. The diameter of the internal hole of the screen 2 is smaller than the diameter of the internal hole of the screen 2 5, and the hole of the screen 2 5 is staggered with the hole of the screen 2.

[0041] A hole is provided on one side of the screen frame 24, and the hole of the screen frame 24 is arranged interchangeably with the delivery pipe 26. The delivery pipe 26 is arranged to be an L-shaped pipe structure, and the bottom end of the delivery pipe 26 passes through one end of the screen frame 24 and is flush with the surface of the screen mesh 25, and the delivery pipe 26 is symmetrically arranged with the delivery pipe 13. The upper end of the screen frame 1 and the upper end of the screen frame 24 are provided with a material equalizing component for evenly spreading the material entering the screen frame 1 and the screen frame 24 to prevent the screen frame 1 and the screen frame 24 from being overloaded as a whole. The outer wall surfaces of the screen frame 24 and the screen frame 1 are provided with an annular convex structure, and the interior of the convex structure of the screen frame 1 and the screen frame 24 is equidistantly penetrated by a positioning pipe 7, and a positioning nut 8 is provided on the surface of the positioning pipe 7, and a non-slip silicone gasket is provided on the surface of the positioning nut 8;

[0042] Combined with the drawings in the specification Figure 1-6 As shown, when in use, the screen frame 1 and the screen frame 2 4 are stacked and installed in a limited position, as shown in FIG. Figure 1 As shown, the screen 1-2 installed inside the screen frame 1 is flush with the screen 2-5 inside the screen frame 2-4, and then the positioning tube 7 is passed through the annular raised structure provided on the outer wall, so that the center lines of the screen frame 1 and the screen frame 2-4 are aligned, and the positioning nuts 8 provided on the surface of the positioning tube 7 are respectively installed at the bottom ends of the screen frame 1 and the screen frame 2-4, which are used to keep the whole stable during the swing screening operation, wherein the delivery tube 1-3 provided on one side of the screen frame 1 is used to remove particles that have not been screened by the screen 2, and the delivery tube 2-6 provided on the side wall of the delivery tube 2-6 of the screen frame 2-4 is used to remove particles that have not been screened by the screen 1-2. The particles screened by screen 2-5 are designed with a circular swinging design for the entire screening frame. The stable swinging motion of the screening frame is achieved through a specific mechanical structure. The swinging motion causes the material to continuously roll and disperse during the screening process, thus avoiding material accumulation and unbalanced loading. At the same time, the two-layer screening structure of screen 1-2 and screen 2-5 can be designed with different apertures as needed to meet different screening requirements. The double-layer screening structure greatly improves the screening efficiency and reduces the screening time and number. At the same time, the screening at different levels can be adjusted and optimized according to the characteristics of the material, thereby improving the adaptability and flexibility of screening.

[0043] The material leveling components include:

[0044] The spiral material distribution frame 9 is installed on the surface of the screen 2, and the top of the spiral material distribution frame 9 is against the bottom of the screen 5. The spiral material distribution frame 9 is composed of a cylinder and an inclined spiral plate, and the spiral material distribution frame 9 is placed inside the screen frame 1;

[0045] The constricting ring 10 is located above the screen frame 1 and is installed at the top of the positioning tube 7;

[0046] The positioning ring frame 11 is installed on the inner wall of the convergence ring 10, and the positioning ring frame 11 is aligned and parallel to the screen frame 2 4;

[0047] A tapered guide column 12 is installed inside the positioning ring frame 11, and the tapered guide column 12 is configured as a tapered main body structure;

[0048] The material balancing plate 13 is located inside the positioning ring frame 11 and is installed at the bottom end of the tapered guide column 12. The top end of the tapered guide column 12 passes through the middle opening of the limiting and concentrating bucket 14, and the top end of the limiting and concentrating bucket 14 is engaged with the positioning ring frame 11.

[0049] The limiting and concentrating bucket 14 is mounted on the upper end of the positioning ring frame 11, and the middle portion of the limiting and concentrating bucket 14 is set as an open structure;

[0050] Combined with the drawings in the specification Figure 1-6 As shown, the spiral material distributor 9 placed on the surface of the screen 2 cooperates with the swinging motion to screen the material to the periphery. The positioning ring frame 11 at the upper end of the screen frame 1 is installed on the top of the positioning tube 7 in conjunction with the convergence ring 10, as shown in FIG. Figure 2-5 As shown, the conical guide column 12, the material distribution plate 13 and the limiting concentration bucket 14 installed inside the positioning ring frame 11 constitute a funnel rotating structure. The material is pushed toward the surface of the conical guide column 12 through the inclined surface of the limiting concentration bucket 14. The material passes through the gap between the conical guide column 12 and the limiting concentration bucket 14 and slides toward the material distribution plate 13. The material is evenly scattered downward through multiple holes opened on the surface of the material distribution plate 13, so that the material is evenly distributed on the entire screening frame surface, ensuring that each area of the screen 2 can fully screen the material.

[0051] Working principle: When using the anti-biased load circular swing double screening frame with evenly distributed feeding, as the positioning tube 7 passes through the outer wall convex structure of the screen frame 1 and the screen frame 2 4 to maintain stability, the other equipment at the bottom of the positioning tube 7 and the bottom of the circular swing double screen are installed. As the material enters the limiting concentration bucket 14 placed on the top of the positioning ring frame 11, it accumulates in the screen frame structure composed of the tapered guide column 12, the material balancing plate 13 and the positioning ring frame 11, and is guided by the tapered inclined surface of the tapered guide column 12, so that the material passes through the material balancing plate 13. 3 Multiple opening channels enter the screen 2 5, and larger materials are discharged outward through the delivery pipe 2 6, and the remaining materials enter between the screen 2 below and the spiral distribution frame 9. As the screen frame 1 drives the screen 2 to swing, screening is performed. With the spiral structure of the spiral distribution frame 9, the larger particles of material are guided to the delivery pipe 3 for discharge during the swinging process, so that the material can be evenly sprinkled on the circular swing double screening frame, effectively avoiding material accumulation and unbalanced loading, improving the accuracy and stability of screening, and increasing the overall practicality.
