Description

Technical Field

[0001] The utility model relates to the plastic particle production industry and therefore provides a sorting type bellows. Background Art

[0002] During the preparation process of plastic particles, there may be a large amount of debris, dust, or small particle products that do not meet the requirements. Therefore, it is necessary to screen out such waste materials without affecting normal production operations. In the prior art, vibrating screens, feeders and other equipment are generally used for feeding operations. During the use of such feeding operations, first of all, the equipment occupies a large area, especially the horizontal area, which will cause the production line to be extended and the volume structure to be relatively large, which is not conducive to a fast production environment. Summary of the invention

[0003] The utility model aims to at least solve the problems of slow speed, complex and redundant structure of the screening mechanism in the prior art. The utility model provides a sorting bellows, which realizes the screening work in the process of rapid circulation. The technical scheme provided is: a sorting bellows, which includes a bellows body for sorting materials, the top of the bellows body is a feed port, the bottom of the bellows body is a first discharge port, and the side of the bellows body is a second discharge port; a feed pipe is connected to the feed port at the top of the bellows body; wherein the top of the bellows body is a wind selection part, the inner wall of the wind selection part is fixedly connected with a feeding channel extending downward in a spiral shape along the inner wall, the second discharge port is opened at the passing position of the feeding channel, and a second discharge pipe is connected at the position of the second discharge port, and the second discharge pipe is formed on one side of the wind selection part tangent to the feeding channel. Furthermore, the lower edge of the second discharge port is higher than the bottom surface of the feeding channel, and a baffle portion is formed between the bottom surface of the feeding channel and the lower edge of the second discharge port to prevent large particles from being blown out. Furthermore, the second discharge port is located on the feeding channel and has a stepped boss.

[0004] Furthermore, the bottom of the air selection section is connected to a material discharge section in the shape of a prismatic cone barrel, and the material of the air selection section enters the material discharge section and is then contained in the material discharge section.

[0005] Further, a discharge pipe is connected to the first discharge port, a discharge baffle is installed at the bottom of the discharge pipe, and the discharge baffle is hinged at the first discharge port through a torsion spring. Further, the diameter of the discharge portion is larger than the diameter of the air selection portion, further, the feed channel is an L-shaped channel or a tubular channel, and further, the feed port is connected to the inlet end of the feed channel.

[0006] The beneficial effects compared with the prior art are:

[0007] 1. Through the spiral feeding channel and the oblique feeding port, the materials will be automatically separated at the discharge port during use. If multiple devices are cascaded, fast feeding can be achieved while distinguishing materials of different particle sizes.

[0008] 2. Also as a gravity screening mechanism, the existing vibrating screen is generally diffusion screening. The material needs to stay at the screening equipment and then be lifted after the screening is completed. This solution can ensure the flow of materials and achieve separation during the flow process. The flow method of this solution ensures two operation modes: rapid transportation and rapid screening.

[0009] 3. The structure of this mechanism is relatively simple. In actual use, the screening effect is good. The structure of this mechanism is simple. During the combined use of various components, the equipment has fewer active components and good durability. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0014] A sorting bellows is provided, which includes a bellows body for sorting materials, the top of the bellows body is a feed port 6, the bottom of the bellows body is a first discharge port 4, and the side of the bellows body is a second discharge port c; through the separation design of the first discharge port 4 and the second discharge port c, during use, the two discharge ports can respectively send out materials of different particle sizes, and the double-particle size materials can be transported outward to realize automatic sorting of materials. The automatic implementation structure of the above sorting is that first, a feed pipe is provided, and the feed pipe is connected to the feed port 6 at the top of the bellows body. The material is fed into the box through the feed port 6. After the material enters, it will arrive at the feeding channel b extending downward in a spiral shape. Since the material is under positive pressure after entering, during the transportation process, the material will spiral and fall along the feeding channel b. The top of the bellows body is a wind selection part 1, and the inner wall of the wind selection part 1 is fixedly connected with the feeding channel b extending downward in a spiral shape along the inner wall, and the top cover of the wind selection part 1 is equipped with a top cover 5.

[0015] The second discharge port c is opened at the position where the feeding channel b passes, and the second discharge pipe 1d is connected to the second discharge port c. The second discharge pipe 1d is formed on one side of the air separation part 1 tangent to the feeding channel b. Since the material is opened tangently, the light material and the heavy material will be at different heights during the material transportation process, and the light material will be scattered. In particular, the second discharge port c is located at a position where a stepped boss d is formed on the feeding channel b. Due to the design of the stepped boss here, the scattering force of the material will be increased. Therefore, this feature can be used to design a baffle to separate the two. The structure of the baffle is that the lower edge of the second discharge port c is higher than the bottom surface of the feeding channel b, and a baffle portion is formed between the bottom surface of the feeding channel b and the lower edge of the second discharge port c to prevent large particles from being blown out. The baffle portion can ensure that the material is blocked by the baffle portion when passing through the discharge port, and the light material will be separated in a straight line when passing through the baffle portion because it is higher than the baffle portion. Therefore, multiple bellows can be cascaded. The combination of multiple bellows can ensure that the material can still be screened for broken slag, tiny particles, and other defective products during the continuous falling process, ensuring the stability of product quality and preventing complaints. The screened material will directly enter the bottom of the air selection part 1 during the falling process. The bottom of the air selection part 1 is connected to a prismatic cone-shaped material discharge part 2. The upper and lower ends of the material discharge part 2 are both tapered cones. The material of the air selection part 1 enters the material discharge part 2 and is contained in the material discharge part 2. The first discharge port 4 is connected to a discharge pipe 4, and a discharge baffle is installed at the bottom of the discharge pipe 4, and the discharge baffle is hinged at the first discharge port 4 through a torsion spring. There are two designs of the discharge baffle here. The first one can choose to use a torsion spring, and the torsion spring automatically dumps the material after the weight of the material exceeds a critical value, or use a reversing solenoid valve gate to regularly flip the gate to allow the material to fall.

[0016] To ensure excellent accommodation performance, the diameter of the material discharge section 2 is larger than the diameter of the air separation section 1. To ensure the continuity of the material during transportation, the material feeding channel b is formed by the material feeding folding plate a fixed on the inner wall of the air separation section 1 and the inner wall of the air separation section 1 to form a spiral channel. The material feeding channel b is an I-shaped channel or a tubular channel. The material feed port 6 is connected to the inlet end of the material feeding channel b.

[0017] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
