[0002] During the production process of plastic particles, a particle mixer is needed to mix the plastic particles. The existing plastic particle mixing device mixes the plastic particles entirely by the force generated by the rotation of the stirring piece. As the number of plastic particles increases, they will pile up together, resulting in the inability to fully mix the plastic particles, especially the plastic particles accumulated at the bottom of the interior. It is difficult to mix and stir. A plastic particle mixer with uniform mixing, application number CN202221759927X, includes a frame, a stirring barrel, a servo motor and a spiral stirring piece; the stirring barrel can rotate slowly, and the plastic particles at the top of the stirring barrel will slowly flow to the bottom of the stirring barrel, and at the same time, with the stirring effect of the spiral stirring blade, the plastic particles at different heights can be fully mixed, thereby ensuring the stirring effect of the plastic particles.

[0003] Although the device has the above advantages, it still has the following defects when actually used:

[0004] 1) When the device mixes the plastic particles up and down, whether it is the spiral push or the up and down rotation of the mixing barrel, there is a problem of low mixing efficiency of the plastic particles;

[0005] 2) When the device mixes plastic particles by spiral pushing, the spiral extrusion and the gravity of plastic accumulation will increase the friction between the plastic particles, causing the surface of the plastic particles to heat up and melt during the mixing process, causing the plastic particles to stick together and agglomerate, thus affecting the overall mixing effect.

[0006] Therefore, it is necessary to solve the problems that still exist in the above-mentioned device. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a plastic uniform mixing tank, which solves the problem that when the existing plastic particle mixer is used, the plastic particles are mixed up and down by rotating up and down and pushing with a spiral, resulting in poor mixing effect and low efficiency, and the spiral pushing easily increases the friction of the plastic particles, causing the surface of the plastic particles to heat up, become sticky and agglomerate, thereby affecting the mixing effect of the plastic particles.

[0008] To achieve the above objectives, the utility model is implemented through the following technical solutions: a plastic uniform mixing tank, including a tank body, a circulation mechanism is arranged on the main body of the tank body, the circulation mechanism includes a straw, one end of the straw is connected to the lower part of the tank body, a rotating rod is embedded in the interior of the straw and is rotatably connected, a baffle is fixedly connected to the outer surface of the rotating rod, the outer surface of the baffle is movably connected to the interior of the straw, one end of the straw is connected to a vertical pipe, one end of the vertical pipe is connected to a discharge pipe, one end of the discharge pipe is connected to the upper part of the tank body and extends to the interior of the tank body, an air pipe is connected to the interior of the discharge pipe, a filter plate is arranged inside one end of the air pipe, the other end of the air pipe is connected to the interior of the tank body, and a fan is arranged inside the air pipe.

[0009] Preferably, a pressure equalizing assembly is disposed outside the baffle, and the pressure equalizing assembly includes a connecting pipe, both ends of the connecting pipe are connected to the inside of the suction pipe, and the two ends of the connecting pipe are respectively located on both sides of the outside of the baffle.

[0010] Preferably, filter screens are provided inside both ends of the connecting pipe, and a solid pipe penetrates and communicates inside the connecting pipe.

[0013] Preferably, one end of the spring rod is fixedly connected to a hollow plate, and the outer surface of the hollow plate is fixedly connected to the inside of the connecting tube.

[0014] Beneficial Effects

[0015] The utility model provides a plastic uniform mixing tank. Compared with the prior art, it has the following beneficial effects:

[0016] (1) By setting up a circulation mechanism, the plastic particles at the bottom of the tank body can be circulated to the top of the tank body through the suction pipe, the vertical pipe and the unloading pipe by using wind adsorption. The plastic particles are stirred during the circulation process to improve the overall mixing efficiency and effect of the plastic particles. The mixed plastic particles can be cooled by air flow to avoid the problem of the surface of the plastic particles heating up and melting to cause agglomeration, thereby affecting the mixing effect.

[0017] (2) By setting up a pressure equalizing component, when plastic particles accumulate on one side of the inside of the straw, the negative pressure on the other side of the straw causes the slide to move, thereby sucking in external air through the solid pipe to facilitate the flow of plastic particles and balance the internal air pressure. When the internal pressure inside the tank increases due to the increase of air and the rise in temperature, the slide will also be compressed to move, so that the internal air is discharged through the solid pipe. Therefore, the air inside the tank is heat exchanged through the flow in and out, thereby enhancing the cooling effect on the plastic particles. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Embodiment 1:

The baffle 4 is made of a pressure-resistant and wear-resistant material, and a plurality of baffles 4 are arranged at equal angles around the surface of the rotating rod 3 so as to process the plastic particles in batches, and the surface of the baffle 4 contacts the inner wall of the straw 2 so as to promote its movement when air flows to separate the plastic particles, and the outer surface of the baffle 4 is movably connected to the inside of the straw 2, and one end of the straw 2 is connected with a vertical pipe 6, and the vertical pipe 6 plays a role in connection and conveying The function of the vertical pipe 6 is that one end of the vertical pipe 6 is connected with a discharge pipe 7, and the discharge pipe 7 and the suction pipe 2 are both inclined to facilitate the flow of plastic particles, and the discharge pipe 7 and the suction pipe 2 are mirror-imaged along the center points of the two. As a preferred manner, one end of the discharge pipe 7 can be hinged with a rubber pad through a hinge, and the rubber pad can prevent air from entering the interior of the discharge pipe 7 through the discharge end of the discharge pipe 7. One end of the discharge pipe 7 is connected through the upper part of the tank body 1 and extends to the interior of the tank body 1. The interior of the discharge pipe 7 is connected through an air pipe 8, and a filter plate 9 is arranged inside one end of the air pipe 8. The filter plate 9 can filter the plastic particles for the discharge of the plastic particles. The other end of the air pipe 8 is connected with the interior of the tank body 1, and a fan 10 is arranged inside the air pipe 8. The driving machine of the fan 10 is made of a high-temperature resistant explosion-proof motor and is electrically connected to an external control circuit.

[0026] By setting up a circulation mechanism, the plastic particles at the lower part of the tank body 1 can be circulated to the upper part of the tank body 1 through the suction pipe 2, the vertical pipe 6 and the unloading pipe 7 by utilizing wind adsorption, and the plastic particles are stirred during the circulation process to improve the overall mixing efficiency and effect of the plastic particles. The mixed plastic particles can be cooled by air flow to avoid the problem of the surface of the plastic particles heating up and melting to cause agglomeration, thereby affecting the mixing effect.

[0027] Embodiment 2:

[0028] The baffle 4 is provided with a pressure equalizing assembly 5 outside, and the pressure equalizing assembly 5 includes a connecting pipe 51, which is made of a material that is resistant to pressure and high temperature corrosion. Both ends of the connecting pipe 51 are connected to the inside of the straw 2, and the two ends of the connecting pipe 51 are respectively located on both sides of the outside of the baffle 4. Filters 52 are provided inside both ends of the connecting pipe 51. The filter 52 is made of a material that is resistant to pressure, wear and high temperature corrosion, and can filter plastic particles. A fixed pipe 53 is connected to the inside of the connecting pipe 51, and one end of the fixed pipe 53 is fixedly connected to a fixed ring 54, which plays a role in connecting support and sealing. The outer surface of the fixed ring 54 is fixedly connected to the interior of the connecting tube 51. The ring hole of the fixed ring 54 is movably connected with a sliding plug 55. The sliding plug 55 is made of a material that is resistant to pressure, wear, high temperature corrosion and has good sealing performance. At the same time, both ends are arranged in a truncated cone shape to facilitate air to push it to slide. The outer surface of the sliding plug 55 is fixedly connected to a spring rod 56. The spring rod 56 is made of a material that is resistant to pressure, wear and fatigue. One end of the spring rod 56 is fixedly connected to a hollow plate 57. The hollow plate 57 plays a role of connecting support and air circulation. The outer surface of the hollow plate 57 is fixedly connected to the interior of the connecting tube 51.

[0029] By providing the pressure equalizing component 5, when the plastic particles accumulate on one side of the inside of the straw 2, the negative pressure on the other side of the inside of the straw 2 causes the slide plug 55 to move, thereby sucking in the external air through the fixed pipe 53, so as to facilitate the flow of the plastic particles and balance the internal air pressure. When the internal pressure inside the tank body 1 increases due to the increase of air and the rise of temperature, the slide plug 55 will also be compressed to move, so that the internal air is discharged through the fixed pipe 53, so that the air inside the tank body 1 is also heat exchanged through the flow in and out of the air, so as to enhance the cooling effect on the plastic particles.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] During operation, the plastic particles to be mixed are added into the tank body 1, and then the plastic particles are stirred and mixed by the stirring element. In the process, the fan 10 works through the air pipe 8, the discharge pipe 7, the vertical pipe 6 and the suction pipe 2 to absorb the air at the bottom of the tank body 1 and blow it to the top of the tank body 1. Through the circulation of air, the plastic particles accumulated at the bottom of the tank body 1 follow the movement of the air to circulate to the top of the tank body 1, thereby improving the overall mixing efficiency and effect through the up and down circulation of the plastic particles and the stirring and mixing of the stirring element. In the process of the circulation of the plastic particles, on the one hand, the baffle 4 can process them in batches by rotating around the rotating rod 3, and on the other hand, the air flow cools them down. At the same time, when the plastic particles are accumulated on one side of the suction pipe 2, it causes Negative pressure is generated on the other side of the straw 2, thereby driving the slide plug 55 to move through the negative pressure, and compressing the output end of the spring rod 56 to facilitate the reset of the slide plug 55 after the air pressure is balanced. Then, after the slide plug 55 is disconnected from the fixed ring 54, external air enters the interior of the straw 2 through the fixed tube 53, the annular hole of the fixed ring 54 and the connecting tube 51, thereby making the internal air pressure balanced, so that it is convenient for the air to push the plastic particles to move to prevent them from accumulating and clogging. When the internal pressure inside the tank body 1 increases due to the increase of air and the increase of air temperature, the air compresses the slide plug 55 and moves, and is discharged to the outside through the fixed tube 53, so that the inside of the tank body 1 is cooled down by the flow of air in and out, so as to maintain the balance of the internal air pressure and the cooling effect on the plastic particles, thereby avoiding the problem of agglomeration of plastic particles during stirring and mixing.
