Description

Technical Field

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

[0002] Modified plastics are materials whose physical, chemical, or mechanical properties are improved by adding various modifiers (such as fillers, plasticizers, stabilizers, flame retardants, etc.) to base plastics. Modified plastics are widely used in automobiles, electronics, construction, packaging and other fields. Their performance directly depends on the uniformity of mixing between the modifier and the base plastic. Therefore, the mixing process in the production of modified plastics is crucial.

[0003] Traditional modified plastic mixing equipment typically uses simple stirring devices to mix modifiers with base plastics through mechanical stirring. During the mixing process, volatile organic compounds are generated inside the mixing tank. However, traditional mixing equipment does not have the ability to remove volatiles, and the volatiles generated during the mixing process can easily escape into the outside air, which not only pollutes the working environment but also poses a potential hazard to the health of workers. Utility Model Content

A motor is installed on the top of the mixing tank, and the output shaft of the motor is located inside the mixing tank. A stirring shaft is installed inside the mixing tank, and the stirring shaft is connected to the output shaft of the motor through a coupling. Multiple evenly distributed stirring blades are installed on the stirring shaft.

[0007] The top of the cover is provided with an exhaust port, and an exhaust fan is installed on the exhaust port. The side of the cover is provided with two vertically distributed drawer slots, and each drawer slot is provided with a drawer. The bottom of the inner side of the drawer is provided with a rectangular through hole, and a support mesh is installed at the through hole. Activated carbon is placed inside the drawer.

[0027] like Figures 1 to 5 As shown, this utility model provides a modified plastic mixing device, including a mixing tank 1, a lid 2, a one-way valve 3, a cover 4, an exhaust fan 5, a drawer 6, a support net 7, activated carbon 8, a motor 9, a stirring shaft 10, a stirring blade 11, a valve 12, a support leg 13, a controller 14, a first handle 15, an external threaded cylinder 16, a sealing ring 17, a second handle 18, a positioning block 19, a positioning screw 20, a nut 21, and a sealing gasket 22.

[0028] Please see Figure 1 The mixing tank 1 has a feed inlet, an air inlet, and an air outlet at its top, and a cover 2 is installed on the feed inlet; please refer to Figure 5 The bottom of the cover 2 is equipped with an external threaded cylinder 16 and a sealing ring 17. The inner side of the inlet of the mixing tank 1 has an internal thread that mates with the external threaded cylinder 16. The cover 2 is threadedly connected to the inlet of the mixing tank 1. The sealing ring 17 ensures a tight seal between the cover 2 and the inlet of the mixing tank 1. The top of the cover 2 is equipped with a first handle 15, which facilitates rotation of the cover 2 by the worker. Please refer to [link / reference]. Figure 4 The bottom of the mixing tank 1 is funnel-shaped, and the outlet of the funnel is the discharge port of the mixing tank 1. A valve 12 is installed on the discharge port to control the discharge of the mixed modified plastic. Four support legs 13 are also installed at the bottom of the mixing tank 1 to stably support the entire device.

[0029] Please see Figure 4 A motor 9 is installed on the top of the mixing tank 1. The output shaft of the motor 9 is connected to the stirring shaft 10 through a coupling. Multiple evenly distributed stirring blades 11 are installed on the stirring shaft 10. The motor 9 can drive the stirring shaft 10 and the stirring blades 11 to rotate, thereby achieving uniform mixing of the modified plastic raw materials. A controller 14 is installed on the side of the mixing tank 1 to control the switch of the motor 9. The worker can adjust the mixing speed through the controller 14.

[0030] Please see Figures 1-3A cover 4 is installed on the air outlet of the mixing tank 1. The top of the cover 4 has an exhaust port, and an exhaust fan 5 is installed on the exhaust port. Its function is to exhaust the air inside the mixing tank 1. The exhaust fan 5 is controlled by a controller 14. The worker can adjust the exhaust intensity of the exhaust fan 5 through the controller 14. There are two vertically distributed drawer slots on the side of the cover 4. Each drawer slot has a drawer 6. The bottom of the inner side of the drawer 6 has a rectangular through hole. A support net 7 is installed at the through hole. Activated carbon 8 is placed in the drawer 6. Its function is to adsorb volatiles in the air inside the mixing tank 1 and prevent volatiles from escaping into the outside air. The purpose of using the drawer 6 to place the activated carbon 8 is to facilitate the worker to replace the activated carbon 8 later. A one-way valve 3 is installed on the air inlet of the mixing tank 1. The one-way valve 3 allows outside air to enter the mixing tank 1, thereby ensuring the air pressure balance inside the mixing tank 1.

[0031] Please see Figure 2 and Figure 3 A second handle 18 is installed on the front side panel of drawer 6, which facilitates the worker to pull out and push in drawer 6. Four positioning blocks 19 are installed on the edge of the front side panel of drawer 6. The four positioning blocks 19 correspond to the four positioning screws 20 around the drawer slot entrance of cover 4. The positioning blocks 19 have through holes for the positioning screws 20 to pass through. A sealing gasket 22 is affixed to the edge of the drawer slot entrance of cover 4, which ensures the sealing between drawer 6 and cover 4. Nuts 21 are provided on the positioning screws 20. After the positioning screws 20 pass through the through holes on the positioning blocks 19, the drawer 6 can be fixed to cover 4 by installing and tightening the nuts 21, thereby preventing drawer 6 from loosening during the operation of the device.

[0032] Working principle and usage process of this utility model:

[0033] When using the modified plastic mixing device, first open the cover 2 through the first handle 15, pour the modified plastic raw material to be mixed into the mixing tank 1 from the feed port, then close the cover 2 and make the sealing ring 17 fit tightly with the feed port of the mixing tank 1. Start the motor 9 through the controller 14. The motor 9 drives the stirring shaft 10 and stirring blade 11 to rotate, so as to mix the raw material evenly.

[0034] During the mixing process, the exhaust fan 5 is activated by the controller 14. The volatiles generated in the mixing barrel 1 enter the cover 4 through the air outlet along with the air in the barrel. After being adsorbed and filtered by the activated carbon 8 in the drawer 6, the air in the barrel is discharged through the exhaust port on the cover 4.

[0035] After mixing is completed, the worker opens valve 12 to discharge the mixed modified plastic from the discharge port of mixing tank 1. If activated carbon 8 needs to be replaced, the worker can first remove nut 21 on positioning screw 20, then pull out drawer 6 through second handle 18, replace the new activated carbon 8, push drawer 6 into cover 4, and tighten nut 21 back onto positioning screw 20.

[0036] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
