Description

Technical Field

[0001] The present application relates to the technical field of mixers for producing degradable plastics, and in particular to a mixer for producing degradable plastics. Background Art

[0002] Degradable plastic refers to a type of plastic whose products' various properties can meet the requirements of use. The properties remain unchanged during the shelf life, and after use, they can be degraded into environmentally harmless substances under natural conditions. Therefore, they are also called environmentally degradable plastics. During the production process of degradable plastics, a mixer is required to stir the raw materials.

[0003] For example, a Chinese patent (publication number: CN216372871U) discloses a variable frequency high-speed mixer for the production of biodegradable plastics, including a mixing barrel. Through the cooperation between the driving motor, the mixing shaft, the mixing rod, the fixed rod and the side plate, the mixing rate can be increased while the raw materials adhered to the inner wall of the mixing barrel can be scraped to avoid waste of raw materials. The cooperation between the fixed groove, the plug plate, the T-shaped rod and the spring facilitates the removal of the top cover from the mixing barrel, thereby facilitating the cleaning of the mixing tool and the inner cavity of the mixing barrel, thereby improving the mixing quality and the production quality of biodegradable plastics.

[0004] However, the above-mentioned search patent still has some shortcomings. When it is used, multiple stirring rods are arranged to revolve around the stirring shaft for stirring. The stirring trajectories of the multiple stirring shafts are relatively stable and single, which makes the stirring and mixing efficiency low and inconvenient to use. Therefore, a mixer for the production of degradable plastics is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides a mixer for the production of biodegradable plastics, which has the advantages of high stirring efficiency and good mixing effect, and solves the problem of low stirring and mixing efficiency of the device disclosed in the above-mentioned search patent when in use.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: A mixer for the production of biodegradable plastics, comprising a mixing chamber, a support seat fixed to the bottom surface of the mixing chamber, a top cover fixed to the top surface of the mixing chamber, a feed hopper fixed to the top surface of the top cover, a discharge pipe fixed to the bottom surface of the mixing chamber, and a mixing mechanism arranged in the mixing chamber;

[0007] The stirring mechanism includes a motor fixed on the bottom surface of the stirring chamber, a diverter pipe fixed on the top of the motor output shaft, two support pipes rotatably connected to the top surface of the diverter pipe, a stirring plate fixed on the top of the support pipe, a center pipe fixed on the top surface of the diverter pipe and a spiral blade fixed on the outer peripheral wall of the center pipe.

[0008] By adopting the above technical solution, when in use, the biodegradable plastic production raw materials are poured into the mixing bin through the feed hopper, and the motor provided by the mixing mechanism drives the two mixing plates to revolve, thereby achieving the mixing effect.

[0009] Furthermore, the stirring mechanism also includes a gear ring fixed on the lower surface of the top cover, a connecting pipe fixed on the top surface of the stirring plate, a gear fixed on the outer peripheral wall of the connecting pipe and meshing with the gear ring, and a heating mechanism arranged on the stirring chamber.

[0010] By adopting the above technical solution, the two stirring plates can also be driven to rotate by the gears, gear rings and other structures provided in the stirring mechanism while performing orbital stirring, thereby improving the efficiency of stirring and mixing the raw materials for the production of degradable plastics, achieving the purpose of efficient mixing, and further increasing the practicality of the device.

[0011] Furthermore, the heating mechanism includes an air inlet pipe rotatably connected to the top of the central tube, a recovery bin fixed on the upper surface of the top cover, an air outlet pipe fixed on the top surface of the recovery bin, a recovery pipe rotatably connected to the bottom surface of the recovery bin and a collecting pipe fixed at the bottom end of the recovery pipe, and the top of the connecting pipe is rotatably connected to the bottom surface of the collecting pipe.

[0012] By adopting the above technical scheme, when the stirring plate stirs the biodegradable plastic production raw materials, steam or high-temperature liquid medium can be transported to the inside of the stirring plate through the air inlet pipe arranged by the heating mechanism, and the medium can be recovered through the air outlet pipe, so as to achieve the effect of uniformly heating the production raw materials and realize the thermal stirring treatment of the biodegradable plastic production raw materials.

[0013] Furthermore, the mixing chamber and the top cover are both circular chambers with hollow interiors, the top surface of the mixing chamber is open, the bottom surface of the top cover is open, and the top cover and the mixing chamber are fixed by connecting plates and bolts.

[0014] The above technical solution makes it easy to disassemble the top cover, so that the top cover can be removed when necessary to clean and maintain the inside of the mixing chamber.

[0015] Furthermore, two feed hoppers are provided and distributed on the left and right, and the bottom ends thereof extend into the interior of the mixing bin. A glass observation window is installed on the front of the mixing bin, and a discharge valve is fixed on the outer peripheral wall of the discharge pipe.

[0016] By adopting the above technical solution, the stirring effect can be observed through the glass observation window, and the discharge valve can be used to control the stirring raw materials to be discharged from the discharge pipe.

[0017] Furthermore, the two support tubes are respectively close to the left and right ends of the diversion tube, the stirring plate is a hollow plate, and the central tube, the stirring chamber and the motor output shaft are all located on the same central axis.

[0018] By adopting the above technical solution, it is convenient to drive the two stirring plates to revolve around the central axis of the stirring chamber through the motor and the diversion pipe, and at the same time make the central pipe rotate and drive the spiral blades to rotate, so as to improve the production material and increase the stirring efficiency.

[0019] Furthermore, the connecting tube and the supporting tube are opposite to each other in upper and lower directions, and the two are located on the same central axis as the stirring plate, the gear is arranged on the inner side of the gear ring, and the gear ring and the motor output shaft are located on the same central axis.

[0020] The above technical solution is adopted to facilitate the stirring plate to revolve around the central axis of the stirring chamber, thereby driving the gear to revolve around the central axis of the stirring chamber. Since the gear ring is meshed with the gear and the gear ring is coaxial with the stirring chamber, the gear is driven by the gear ring to rotate during the revolution, driving the stirring plate to rotate, thereby further improving the stirring and mixing efficiency and effect.

[0021] Furthermore, the air inlet pipe is fixed on the top surface of the recovery bin, the central pipe vertically penetrates the collecting pipe and the recovery pipe, and the recovery pipe and the central pipe are located on the same central axis.

[0022] The above technical solution is adopted to prevent the stirring plate from driving the air inlet pipe and the air outlet pipe to rotate, thereby facilitating the connection of the air inlet pipe and the air outlet pipe with the external steam generating device.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

When the mixer for the production of degradable plastics is in use, the raw materials for the production of degradable plastics are poured into the mixing bin through the feed hopper, and the motor provided by the mixing mechanism drives the two mixing plates to revolve, thereby achieving the effect of mixing and stirring. At the same time, the two mixing plates can be driven by the provided mixing mechanism to rotate, thereby improving the efficiency of mixing and stirring the raw materials for the production of degradable plastics, achieving the purpose of efficient mixing, and further increasing the practicability of the device.

The connecting pipe 608 drives the gear 609 to revolve around the central axis of the stirring chamber 1. Since the gear ring 607 is meshed with the gear 609 and the gear ring 607 is coaxial with the stirring chamber 1, the gear 609 is driven by the gear ring 607 to rotate during the revolution. Furthermore, the gear 609 drives the connecting pipe 608 to rotate, and the connecting pipe 608 drives the stirring plate 604 to rotate, thereby further improving the stirring and mixing efficiency and effect.

The steam enters the central pipe 605 through the air inlet pipe 701, and then enters the branch pipe 602 from the central pipe 605, and further enters the two hollow stirring plates 604 through the two support pipes 603, so that the stirring plates 604 can heat the production raw materials during stirring, thereby achieving the effect of hot stirring. Furthermore, the steam entering the stirring plates 604 enters the collecting pipe 705 through the connecting pipe 608, and then enters the recovery bin 702 through the recovery pipe 704, and is then sent back to the external steam generating device through the air outlet pipe 703 for recycling.
