Description

Technical Field

[0001] The utility model relates to the technical field of extrusion, in particular to a mixing extrusion device. Background Art

[0002] The main raw material for making carbon molecular sieves is the flower arrangement mud made of phenolic plastic foam. After processing, the raw material is mixed with water, asphalt, resin and other additives, and then extruded by an extruder. Unlike dry granular materials, the phenolic plastic foam mixed with the additives becomes a fluid with a certain viscosity. Figure 1 The barrel shown in the figure is particularly prone to sticking to the wall when feeding, and is easy to solidify after being dehydrated. Currently, there are two ways to clean the barrel wall: Figure 1 The foot shown is loosened from the barrel, and the barrel is specially cleaned, but the barrel is fixed by bolts. The long-term loosening and fixing will affect the fixing accuracy and tightness. Therefore, it is necessary to propose a mixing and extrusion device that does not change the barrel fixing method but can simply clean the adhesion on the inner wall of the barrel.

DETAILED DESCRIPTION

[0022] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0024] The specific embodiments of the present utility model are described below with reference to the accompanying drawings.

[0025] Example 1

[0026] In this embodiment, a mixing and extruding device is proposed. Figure 1 For reference and see Figure 2-Figure 4 The mixing and extruding device includes a frame 1, an extrusion barrel, a screw 7 in the extrusion barrel and the screw 7 coincides with the axis of the extrusion barrel, and a barrel 8.

[0027] See also Figure 2 The frame 1 is a frame structure with two frame extensions 2 on top. The two frame extensions 2 are fixed structures for the extrusion barrel. There is also a shell 11 at the position of the frame extension 2. The shell 11 frames the extrusion barrel to play a protective role.

[0028] Please continue reading Figure 2 The extrusion cylinder includes a first cylinder 3, a second cylinder 4, a third cylinder 5 and an extrusion part 6. The first cylinder 3, the second cylinder 4, the third cylinder 5 and the extrusion part 6 are composed of Figure 2 The installation direction is from left to right, and the installation method is fixed by bolts. It should be added that the second tube 4 and the third tube 5 are heating sections, and the heating method is electric heating, preferably Figure 2 The heating section 10 shown is also equipped with an instrument 12, which has a sensor for monitoring temperature and other data.

[0029] In this embodiment, Figure 2 The screw 7 shown enters the first barrel 3, the second barrel 4 and the third barrel 5. The screw 7 is also equipped with a motor (not shown in the figure) for driving the screw 7 to rotate axially in the extrusion barrel.

[0030] See also Figure 2 and Figure 3 The first tube 3 is equipped with a Figure 3 The barrel 8 shown in the figure has a barrel fixing portion 13 fixedly connected to the first barrel 3 at the bottom of the barrel 8. It should be noted that in this embodiment, the barrel fixing portion 13 is still Figure 1 Therefore, even if the shape of the barrel 8 is adjusted, there is no need to adjust the fixing method between the first barrel 3 and the barrel fixing portion 13.

[0031] Further explanation, by Figure 2 and Figure 3 As shown, the barrel 8 is a conical shell with a top diameter larger than a bottom diameter, which facilitates the collection of the mixed material in the barrel. In addition, there is a rotary cutting structure 9 in the barrel 8.

[0032] For further explanation, see Figure 3 and Figure 4The rotary cutting structure 9 includes a funnel 91 adapted to the shape of the barrel 8, a mesh 95 at the bottom of the funnel 91, four scrapers 92 in contact with the inner wall of the barrel 8 above the funnel 91, and a ring sleeve 94 connecting all the scrapers 92. As described above, when the ring sleeve 94 is rotated, the scrapers 92 cut the inner wall of the barrel 8, and the funnel 91 holds the cut object.

[0033] See also Figure 3 In this embodiment, the funnel 91 is preferably located below the center line of the barrel 8, and the scraper 92 should have a certain thickness. The above arrangement has three advantages: first, low production cost; second, it can stir the mixture in the barrel 8 to a certain extent; and third, it can clean the mixture adhered to the inner wall of the barrel 8 or even the solidified material.

[0034] It is further explained that compared with placing a funnel 91 inside the barrel 8 that can completely fit the entire inner wall of the barrel 8, the funnel 91 located below the center line of the funnel 91 can significantly save manufacturing materials. In addition, since a scraper 92 with a thickness is provided, when the mixture enters the barrel 8, the scraper 92 can stir the mixture by rotating the funnel 91. Of course, the function of the scraper 92 is not limited to stirring, but can also be used for cleaning. For example, the scraper 92 can scrape off the undried adhesions on the inner wall of the barrel 8, and the scraper 92 can also scrape off the solidified adhesions on the inner wall of the barrel 8 and be caught by the funnel 91.

[0035] To further illustrate, when the scraper 92 cleans the wet adhesive, the adhesive can enter the extrusion barrel through the filter screen 95. When the scraper 92 cleans the solidified adhesive, the adhesive scraped off by the scraper 92 is mostly flake-like, and the flakes cannot pass through the filter screen 95. Therefore, after taking out the funnel 91 and the combined structure, the flakes can be taken out together to prevent the flakes from entering the extrusion barrel.

[0036] It should be noted that the rotary cutting structure 9 proposed in this embodiment further includes a buckle 93 , which is an extension of the scraper 92 . The extension and the scraper 92 form a chamfer that matches the shape of the barrel edge of the barrel 8 .

[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
