[0001] This application relates to the field of granular filtration technology, and more particularly to an EVA granular filtration device. Background Technology

[0002] EVA (ethylene-vinyl acetate copolymer) granules are widely used in many fields such as footwear, packaging, and wire and cable industries due to their excellent flexibility, chemical resistance, and processing properties. Effective filtration of EVA granules is crucial to ensure the quality and performance of the final product during production and subsequent processing.

[0003] During the production process, EVA granules may be mixed with impurities, affecting the quality of the granules. Currently, most filtration devices used for EVA granules employ filter screens for filtration. However, the filtration effect of a single-layer filter screen is not significant enough. Therefore, there is an urgent need for a high-efficiency EVA granule filtration device. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0022] In the description of the embodiments of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the embodiments of this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In addition, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this utility model can be understood according to the specific circumstances.

[0023] This utility model embodiment provides an EVA granule filtration device, such as... Figure 1 and Figure 2 As shown, it includes a feeding pipe 1 and a filtering mechanism 2; the filtering mechanism 2 includes a support body 21, a first filter screen 22 and a second filter screen 23; the first filter screen 22 and the second filter screen 23 are connected to the support body 21 in sequence; the granules first pass through the first filter screen 22 and then through the second filter screen 23; the filtering mechanism 2 is set inside the feeding pipe 1, and the support body 21 is rotatably connected to the feeding pipe 1.

[0024] For example, the pore size of the first filter screen 22 is larger than that of the second filter screen 23. For instance, the first filter screen 22 can be designed with a 10-mesh pore size to intercept larger particulate impurities; the second filter screen 23 can be designed with a 20-mesh pore size to further filter fine impurities, thereby achieving graded filtration and improving filtration efficiency.

[0025] For example, the second filter screen 23 is designed to be detachable and can be detachably connected to the second connecting frame 212 by threads or clips. When the second filter screen 23 becomes clogged or worn due to long-term use, it can be removed and replaced separately, thereby reducing maintenance costs and extending the overall service life of the device.

[0026] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the support body 21 includes a first connecting frame 211, a second connecting frame 212, and a connecting shaft 213; the connecting shaft 213 connects the first connecting frame 211 and the second connecting frame 212; the first connecting frame 211 has an inlet 2111; the connecting shaft 213 has a cavity, one end of which communicates with the inlet 2111, and the other end of which is closed; a first filter screen 22 is disposed on the connecting shaft 213; a second filter screen 23 is disposed on the second connecting frame 212; after the granules enter the inlet 2111, they are first filtered by the first filter screen 22 and then filtered by the second filter screen 23.

[0027] For example, the connecting shaft 213 is tapered, and the cross-sectional dimensions of the connecting shaft 213 decrease sequentially along the direction from the first connecting frame 211 to the second connecting frame 212.

[0028] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the connecting shaft 213 has an opening 2131 in the circumferential direction, and the opening 2131 communicates with the cavity.

[0029] In the embodiments of this application, such as Figure 1 and Figure 2As shown, the support body 21 also includes two baffles 214; both baffles 214 are connected between the first connecting frame 211 and the second connecting frame 212, and the two baffles 214 are spaced apart on both sides of the opening 2131.

[0030] For example, the width of the opening 2131 matches the size of the cavity. For instance, the opening 2131 can be configured as a fan-shaped structure. When the support body 21 rotates to a specific angle via the first connecting frame 211 and the second connecting frame 212, the opening 2131 aligns with the waste collection device outside the discharge pipe 1, facilitating the rapid manual discharge of waste accumulated in the cavity. The waste can slide out along the inclined baffle 214. After cleaning, the filter mechanism 2 can be reset to continue the filtration operation.

[0031] For example, the baffle 214 is made of stainless steel or wear-resistant plastic and its height is higher than the opening 2131. For example, the height of the baffle 214 is 1.2 times the height of the opening 2131. It can guide the waste to the area of ​​the opening 2131, making it convenient for manual discharge of waste.

[0032] In the embodiments of this application, such as Figure 3 and Figure 4 As shown, it also includes an opening and closing assembly 3; the opening and closing assembly 3 includes a material receiving door 31 and a snap-fit ​​component 32; a material receiving channel is provided on the discharge pipe 1 near the filter mechanism 2, and the material receiving door 31 is located at the material receiving channel; one end of the snap-fit ​​component 32 is rotatably connected to the material receiving door 31, and the other end is snapped into the inner wall of the discharge pipe 1.

[0033] In the embodiments of this application, such as Figure 3 and Figure 4 As shown, the opening and closing assembly 3 also includes a hinge 33; a hinge 33 is provided between the material picking door 31 and the material discharge pipe 1, and the material picking door 31 is rotatably connected to the material discharge pipe 1 through the hinge 33.

[0034] In the embodiments of this application, such as Figure 3 and Figure 4 As shown, the opening and closing assembly 3 also includes an observation glass 34; the material handling door 31 is provided with an observation glass 34.

[0035] In the embodiments of this application, such as Figure 3 and Figure 4 As shown, the opening and closing assembly 3 also includes a handle 35; the end of the snap-fit ​​member 32 near the material gate 31 is connected to the handle 35, and the handle 35 is located on the outside of the material discharge pipe 1.

[0036] For example, the observation glass 34 is made of a high-temperature resistant transparent material (such as tempered glass or polycarbonate) and is installed in the upper middle part of the material receiving door 31. Users can monitor the internal filtration status and waste accumulation of the material receiving pipe 1 in real time through the observation glass 34 without having to frequently open the material receiving door 31 for observation.

[0037] For example, by rotating the handle 35, the snap-fit ​​32 can be locked against the inner wall of the discharge pipe 1, so that the material dispensing door 31 remains closed.

[0038] For example, one end of the connecting shaft 213 is pivoted by the first connecting frame 211, and the other end of the connecting shaft 213 is pivoted by the second connecting frame 212. The outer surface of the shaft is provided with a first filter screen 22, thereby completing the primary filtration of EVA granules. The second connecting frame 212 is connected to a second filter screen 23 in the radial direction of the feed pipe 1, which can be used for secondary fine filtration of the granules after primary filtration.

[0039] For example, the first connecting frame 211 and the second connecting frame 212 are coaxially connected by a connecting shaft 213 to form an integral filter unit. When the connecting shaft 213 is rotated, the first connecting frame 211 and the second connecting frame 212 rotate synchronously, thereby aligning the opening 2131 with the material intake channel and achieving centralized cleaning of waste. Through the integral design of the split frame and the connecting shaft 213, the stability of the graded filtration is ensured, and the operation process of rotation cleaning is simplified. Furthermore, the first connecting frame 211, the second connecting frame 212, and the connecting shaft 213 also enhance the mechanical strength of the filter mechanism 2, preventing deformation of the filter mechanism 2 due to particle impact.

[0041] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
