Description

Technical Field

[0001] This utility model relates to the field of modified plastics production technology, specifically to an extrusion device for modified plastics production. Background Technology

[0002] Modified plastics refer to a class of plastic products that are made by adding modifiers (such as fillers, reinforcing fibers, flame retardants, etc.) to general-purpose plastics (such as PE, PP, PVC, etc.) or engineering plastics (such as PA, PC, PBT, etc.) through physical, chemical, or a combination of both methods to change their original properties, thereby enhancing or endowing the new material with specific functions.

[0003] In the current modified plastics production process, the "bridging phenomenon" often occurs. The "bridging phenomenon" refers to the self-supporting arch structure formed at the feed inlet due to gravity compression, friction or adhesion. This can prevent the raw material from entering the extruder normally, making it difficult to carry out the work. At the same time, the equipment generates waste gas during operation. This waste gas, when directly discharged into the air, will pollute the environment and harm the health of the workers. Utility Model Content

[0004] The purpose of this invention is to provide an extrusion device for the production of modified plastics, in order to solve the problems mentioned in the background art, such as the "bridging phenomenon" that often occurs in the production of modified plastics, which prevents the raw materials from entering the extruder normally, making it inconvenient to work, and the generation of harmful gases that pollute the environment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an extrusion equipment for modified plastic production, comprising a twin-screw extruder, wherein a feeding mechanism is provided at the top of the twin-screw extruder, the feeding mechanism includes a feeding trough, a scraper is slidably connected inside the feeding trough, and a stirring block is rotatably connected inside the feeding trough, the stirring block being disposed at the bottom of the scraper to break up large pieces of raw material; a filtration unit is provided on the surface of the twin-screw extruder, the filtration unit including a filter element to filter the exhaust gas discharged from the equipment.

[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 embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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 communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an extrusion equipment for modified plastic production, including a twin-screw extruder 1, a feeding mechanism at the top of the twin-screw extruder 1, the feeding mechanism including a feeding trough 2, a scraper 6 slidably connected inside the feeding trough 2, and a stirring block 5 rotatably connected inside the feeding trough 2. The stirring block 5 is located at the bottom of the scraper 6 to break up large pieces of raw material. A filter unit is provided on the surface of the twin-screw extruder 1, the filter unit including a filter element 13 to filter the exhaust gas discharged from the equipment.

[0024] In this embodiment, the raw material is first placed inside the equipment through the feed port. The motor 3 is turned on, driving the stirring rod 4 to rotate, which in turn drives the scraper 6 to rotate, and simultaneously drives the stirring block 5 to rotate, thus stirring and crushing the raw material. The raw material is then processed by the twin-screw extruder 1. When the twin-screw extruder 1 is working, harmful waste gas is generated. By turning on the exhaust fan 9 and cooperating with the air supply pipe 10, the waste gas generated inside the equipment is drawn from the exhaust port 18 into the processing block 7. The impurities in the waste gas are adsorbed by the adsorption sponge block 11. Water is introduced into the bottom of the filter box 8 by opening the top cover 14. The waste gas is transported into the filter box 8 through the air supply pipe 10. The waste gas is filtered by the water at the bottom and the filter element 13. The filtered gas is discharged through the air outlet 15. After filtration, the wastewater used inside is discharged through the water outlet 17.

[0025] like Figure 2 As shown, the bottom of the feed trough 2 is further designed to be semi-circular.

[0026] In this embodiment, by setting the bottom of the feed trough 2 to be semi-circular, the pressure of the material on the side wall can be reduced, thereby increasing the service life of the equipment.

[0027] like Figure 2 As shown, the feeding mechanism further includes a motor 3, which is fixedly connected to the top of the feeding trough 2. The output end of the motor 3 is fixedly connected to a stirring rod 4, and a scraper 6 is fixedly connected to the surface of the stirring rod 4.

[0028] In this embodiment, by setting a motor 3 to drive the stirring rod 4 to rotate, thereby driving the scraper 6 to rotate, small pieces of raw material are prevented from accumulating on the inner wall of the feed trough 2, which would cause waste of raw materials and increase costs.

[0029] like Figure 2 As shown, the stirring block 5 is further fixedly connected to the surface of the stirring rod 4, and the stirring block 5 is positioned below the scraper 6.

[0030] In this embodiment, by setting the stirring block 5, the raw material can be effectively prevented from forming an arched blockage structure in the feed trough 2, which would prevent the raw material from entering the extruder normally, thus facilitating its use.

[0031] like Figure 4 As shown, further, a processing block 7 is fixedly connected to the surface of the twin-screw extruder 1, an adsorption sponge block 11 is provided inside the processing block 7, and an exhaust port 18 is provided at the bottom of the processing block 7.

[0032] In this embodiment, when the device is producing harmful waste gas, the high-boiling-point oil in the waste gas can be adsorbed and filtered by setting the adsorption sponge block 11, so as to avoid the oil condensing and clogging the pipes and increasing the cleaning cost.

[0033] like Figure 3 As shown, further, a cover 16 is slidably connected to the surface of the processing block 7, and a rubber layer is provided on the surface of the cover 16.

[0034] In this embodiment, by providing a cover 16, it is convenient to replace the adsorption sponge block 11 inside the processing block 7, which facilitates the filtration process.

[0035] like Figure 2 As shown, the filtration mechanism further includes a filter box 8, an air extractor 9 is fixedly connected to the surface of the filter box 8, an air supply pipe 10 is fixedly connected to the output end of the air extractor 9, the end of the air supply pipe 10 away from the air extractor 9 is fixedly connected to the inside of the processing block 7, and a top cover 14 is slidably connected to the top of the filter box 8.

[0036] In this embodiment, the exhaust gas generated inside the equipment is drawn into the filter box 8 by the exhaust fan 9 and the air supply pipe 10. The top cover 14 is opened and water is put into the filter box 8 to filter water-soluble impurities in the exhaust gas.

[0037] like Figure 4 As shown, further, a placement plate 12 is fixedly connected inside the filter box 8, the filter element 13 is disposed on the surface of the placement plate 12, an air outlet 15 is opened on the surface of the filter box 8, and a water outlet 17 is provided on the surface of the filter box 8.

[0038] In this embodiment, by setting the filter element 13, the harmful gases in the exhaust gas are further filtered and treated, and by setting the air outlet 15, the gas after the material is discharged can be discharged into the air.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
