Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and in particular to a mixing device for biodegradable plastic modified materials. Background Technology

[0002] Biodegradable plastics, also known as biodegradable plastics, refer to plastics that degrade under natural conditions such as soil and / or sand, and / or under specific conditions such as composting, anaerobic digestion, or in aqueous culture solutions, caused by the action of naturally occurring microorganisms, and ultimately completely degrade into carbon dioxide, methane, water, and mineralized inorganic salts of their constituent elements, as well as new biomass.

[0003] When producing biodegradable plastic modified materials, it is necessary to mix biodegradable plastic particles with additives. In the existing technology, biodegradable plastic particles and additives are usually added directly to the mixing tank for mixing. However, biodegradable plastic particles are prone to clumping, and adding them together will cause uneven mixing of additives. Therefore, it is necessary to redesign a mixing device for biodegradable plastic modified materials to address this problem. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the background art by proposing a mixing device for biodegradable plastic modified materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mixing device for biodegradable plastic modified materials, comprising:

[0007] Mixing tank;

[0008] A rotating plate is slidably attached to the top of the mixing tank, and the rotating plate is symmetrically fixed through two feed hoppers;

[0009] The mixing assembly includes a rotating shaft fixedly passing through the bottom of a rotating plate. Multiple mixing rods are fixedly installed on the surface of the rotating shaft. A drive motor for driving the rotating shaft to rotate is provided above the rotating plate. A horizontal plate is fixedly installed on the top of the drive motor through a connecting frame. Right-angle frames are fixedly installed at both ends of the horizontal plate, and the other end of the right-angle frames is fixedly installed on the outside of the mixing tank.

[0010] The rotating feeding assembly is placed on the two feeding hoppers respectively, and is used to rotate the raw materials in the two feeding hoppers into the mixing tank.

[0011] Preferably, the rotary feeding assembly includes a fixed plate fixedly installed on the top of the feed hopper, a rotating shaft rotatably passing through the top of the fixed plate, a helical blade fixedly installed on the lower end surface of the rotating shaft, and the side of the helical blade slidingly adhering to the inner surface of the lower port of the feed hopper, and a planetary gear fixedly installed on the upper end of the rotating shaft.

[0012] Both planetary gears have an internal gear ring meshing on their outer sides, and the internal gear ring is fixedly installed at the bottom of the fixed plate.

[0013] Preferably, two support columns are symmetrically fixedly installed at the bottom of the mixing tank, and a fixing seat is fixedly installed at the lower end of the two support columns.

[0014] Preferably, a valve is installed at the lower port of the mixing tank.

[0015] Preferably, multiple crushing blades are fixedly mounted on the surfaces of both rotating shafts.

[0016] Compared with existing technologies, the advantages of the biodegradable plastic modified material mixing device provided by this utility model are as follows:

[0017] 1. The rotating plate is controlled by the drive motor to rotate, which drives the feed hopper to move in a circular motion, so that the planetary gear rolls along the internal gear ring, and the rotating shaft can drive each crushing blade and the spiral blade to rotate. The crushing blade can pre-crush and stir the biodegradable plastic particles and additives to avoid the clumping of biodegradable plastic particles.

[0018] 2. When the rotating shaft drives the spiral blades to rotate, the biodegradable plastic granules and additives can be fed into the mixing tank at a uniform speed. At the same time, the circular motion of the feed hopper can also feed the biodegradable plastic granules and additives into the mixing tank evenly. Finally, with the rotation of each mixing rod, the biodegradable plastic granules and additives are uniformly mixed. Attached Figure Description

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1 to 3 A mixing device for biodegradable plastic modified materials, comprising:

[0025] Mixing tank 1; A valve 17 is installed at the lower port of mixing tank 1, and two support columns 15 are symmetrically fixedly installed at the bottom of mixing tank 1. A fixing seat 16 is fixedly installed at the lower end of the two support columns 15.

[0026] The rotating plate 2 is slidably attached to the top of the mixing tank 1, and two feed hoppers 3 are symmetrically fixed through the rotating plate 2; the mixing assembly includes a rotating shaft 4 fixedly inserted through the bottom of the rotating plate 2, and multiple mixing rods 5 are fixedly installed on the surface of the rotating shaft 4. A drive motor 6 for driving the rotating shaft 4 to rotate is provided above the rotating plate 2. A horizontal plate 8 is fixedly installed on the top of the drive motor 6 through a connecting frame 7. Right angle brackets 9 are fixedly installed at both ends of the horizontal plate 8, and the other end of the right angle bracket 9 is fixedly installed on the outside of the mixing tank 1, which serves to support and fix the drive motor 6.

[0027] A rotary feeding assembly is placed on two feed hoppers 3 and is used to rotary feed the raw materials in the two feed hoppers 3 into the mixing tank 1. The rotary feeding assembly includes a fixed plate 10 fixedly installed on the top of the feed hopper 3. A rotating shaft 11 is rotatably passed through the top of the fixed plate 10. A spiral blade 12 is fixedly installed on the lower end surface of the rotating shaft 11, and the side of the spiral blade 12 slides against the inner surface of the lower port of the feed hopper 3. A planetary gear 13 is fixedly installed on the upper end of the rotating shaft 11. An internal gear ring 14 is meshed on the outer sides of the two planetary gears 13, and the internal gear ring 14 is fixedly installed on the bottom of the fixed plate 10.

[0028] Furthermore, multiple crushing blades 18 are fixedly installed on the surfaces of both rotating shafts 11, so that when the rotating shafts 11 rotate, the biodegradable plastic particles and additives can be pre-crushed and stirred by the crushing blades 18 to avoid the biodegradable plastic particles from clumping, which helps the subsequent mixing operation and reduces the difficulty of mixing.

[0029] The working principle of this utility model is as follows:

[0030] When using, pour the biodegradable plastic granules and additives into the two feed hoppers 3 respectively, and then start the drive motor 6 to control the rotating plate 2 to rotate, which drives the two feed hoppers 3 to move in a circular motion and each mixing rod 5 to rotate.

[0031] When the feed hopper 3 rotates, the planetary gear 13 rolls along the internal gear ring 14, which enables the rotating shaft 11 to drive each crushing blade 18 and the spiral blade 12 to rotate. The crushing blade 18 can pre-crush and stir the biodegradable plastic particles and additives to avoid the biodegradable plastic particles from clumping. The spiral blade 12 can feed the biodegradable plastic particles and additives into the mixing tank 1 at a uniform speed. At the same time, the rotating feed hopper 3 can also feed the biodegradable plastic particles and additives into the mixing tank 1 evenly. Finally, with the rotation of each mixing rod 5, the biodegradable plastic particles and additives are uniformly mixed.

[0032] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.
