[0002] A granulator is a molding machine that can shape materials into specific shapes. It is widely used in material processing and molding processes in the chemical, petrochemical, pharmaceutical, food, building materials, mining, and other fields. Currently, a double-roller extrusion granulator is commonly used to produce granular materials. Double-roller extrusion granulators have grooves on the surfaces of two opposing rollers.

[0031] Example:

[0032] like Figures 1 to 4As shown, the utility model discloses a double-roller extrusion granulator for recycling clean residual materials, comprising a granulator housing 1, an extrusion roller cleaning member 2, a clean residual material recovery assembly 3, and a clean residual material recycling assembly 4. The extrusion roller cleaning member 2 and the clean residual material recovery assembly 3 are both arranged in the granulator housing 1; the extrusion roller cleaning member 2 is used to clean the material attached to the extrusion roller 5, and the clean residual material recovery assembly 3 is used to recover the cleaned material; the feed port of the clean residual material recovery assembly 4 is connected to the clean residual material recovery assembly 3, and the discharge port of the clean residual material recovery assembly 4 is connected to the feed port of the granulator housing 1. In this embodiment, during use of the granulator, the extrusion roller cleaning member 2 can effectively clean the residual residual materials attached to the extrusion roller 5 into the clean residual material recovery assembly 3 for unified storage, thereby preventing the residual materials from mixing with the product and affecting the product quality. Then, the clean residual material recycling assembly 4 is used to circulate the residual materials in the clean residual material recovery assembly 3 back to the granulator for use, thereby effectively avoiding material waste and saving manufacturing costs.

[0033] Specifically, the clean leftover material recycling assembly 4 includes a leftover material crusher 41 and a leftover material stirring device 42. The feed port of the leftover material crusher 41 is connected to the discharge port of the clean leftover material recovery assembly 3, the discharge port of the leftover material crusher 41 is connected to the feed port of the leftover material stirring device 42, and the discharge port of the leftover material stirring device 42 is connected to the feed port of the granulator housing 1. Since the leftover material cannot be directly recycled into the granulator for use after being subjected to the action of the squeezing roller 5, in this embodiment, the leftover material is first crushed by the leftover material crusher 41 and then stirred by the leftover material stirring device 42, thereby processing the leftover material into a state that can be directly recycled into the granulator for use.

[0034] In this embodiment, the residual material baffle 31 can effectively isolate the residual material from the finished material, thereby preventing the residual material from entering the finished product bin and affecting the quality of the finished material. Specifically, the clean residual material recovery component 3 includes a residual material baffle 31, which is enclosed by the side wall of the granulator housing 1, and a cavity structure for recovering and storing residual material is formed between the residual material baffle 31 and the side wall of the granulator housing 1. Furthermore, the clean residual material recovery component 3 also includes a residual material receiving member 32, which is arranged on the top of the residual material baffle 31 and extends to the bottom of the extrusion roller. During the process of cleaning the residual material attached to the extrusion roller 5, the residual material may fall into the finished product from the gap between the extrusion roller 5 and the residual material receiving member 32. At this time, the setting of the residual material receiving member 32 can effectively prevent the residual material from falling into the finished product. Specifically, the other end of the residual material receiving member 32 extends to the bottom of the central axis of the extrusion roller 5. This position can not only effectively ensure that the residual material falls into the collection cavity, but also prevent the residual material receiving member 32 from affecting the normal granulation work.

[0035] The clean residual material recovery assembly 3 also includes an inclined bottom plate 33, which is tilted toward the side wall of the granulator housing 1. The inclined structure of the inclined bottom plate 33 can concentrate residual materials to one side, facilitating their discharge. Furthermore, a residual material outlet 34 is defined at the intersection of the inclined bottom plate 33 and the side wall of the granulator housing 1, and the residual material outlet 34 is connected to the feed inlet of the residual material crusher 41.

[0036] In order to adapt to the structure of a pair of squeezing rollers 5 of the granulator, two squeezing roller cleaning members 2 and two groups of clean residual material recovery components 3 are provided in the granulator housing 1, and the two squeezing roller cleaning members 2 are respectively provided on the two squeezing rollers and used to remove the residual material adhering to the squeezing rollers 5; the two groups of clean residual material recovery components 3 are respectively provided under the two squeezing rollers 5.

[0037] The squeezing roller 5 is provided with an squeezing groove 51 , and the groove structures of the squeezing grooves 51 on the two squeezing rollers 5 are aligned and connected to form a channel for squeezing the strip material.

[0038] The squeezing roller cleaning member 2 is provided with cleaning teeth 21 adapted to the squeezing groove 51 , the tooth bottoms of the cleaning teeth 21 are in contact with the surface of the squeezing roller 5 , and the tooth tops of the cleaning teeth 21 are in contact with the groove bottom of the squeezing groove 51 .

[0039] A granulation product cavity 6 is formed between the two residual material baffles 31 , and a pelletizing roller group 7 is provided in the granulation product cavity 6 .

[0040] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
