Description

Technical Field

[0001] The invention relates to the technical field of rubber recycling, and in particular to a device for desulfurizing and plasticizing waste rubber powder. Background Art

[0002] The desulfurization and plasticization process of rubber powder is one of the key links in rubber recycling. However, when using traditional waste rubber powder desulfurization and plasticization devices, some challenges are often encountered. For example: during the heating process, the rubber powder may be unevenly heated due to agglomeration or improper transportation methods. On the one hand, excessively high temperatures in some areas may cause the rubber powder to burn; on the other hand, areas with too low temperatures cannot achieve the expected desulfurization and plasticization effects. This uneven heating leads to an imbalance in the internal stress distribution of the rubber powder, ultimately affecting the quality and performance of the product. In order to solve the above problems, the present invention provides a waste rubber powder desulfurization and plasticization device. Summary of the invention

[0003] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a waste rubber powder desulfurization and plasticization device, which can transport the heated rubber powder through a vortex ring, spread the rubber powder for transportation, and heat the rubber powder evenly. At the same time, the agglomerated rubber powder can be destroyed before the rubber powder enters the vortex ring, so as to avoid uneven heating of the agglomerated rubber powder or affect transportation.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a waste rubber powder desulfurization and plasticization device, comprising: A base, the upper side of which is fixedly connected with a vortex ring, and the interior of the base is provided with a heating tank for heat transfer oil to flow and provide heat; A top cover, the top cover being rotatably mounted above the vortex ring; A hopper, wherein the hopper is mounted on the top cover; A feeding part, which is installed on the hopper and is used to push the rubber powder dropped on the base into the inlet of the vortex ring; A disturbance rod, which is mounted on the base and disturbs the rubber powder during the rotation of the hopper; The feeding part and the disturbance rod cooperate with each other to shear and destroy the agglomerated rubber powder.

[0005] Preferably, the feeding part comprises an elastic rod, which is located on the upper side of the base and is connected to the inner wall of the hopper via a connecting rod. The elastic rod contacts the side of the vortex ring under the action of its own elastic force.

[0006] Preferably, the disturbance rod is in an inclined state, the angle of the connecting rod is adapted to the disturbance rod, and the corresponding side surfaces of the disturbance rod and the connecting rod are set as mutually matching inclined surfaces, and the upper end height of the connecting rod is lower than the height of the coincidence point of the disturbance rod and the hopper axis.

[0007] Preferably, a guide block is fixedly connected to the upper side of the base, the guide block is conical in shape, and the axis of the guide block is aligned with the axis of the hopper.

[0008] Preferably, the disturbance rod is fixedly connected to the guide block.

[0009] Preferably, a gear ring is fixedly connected to the top cover, the gear ring is meshingly connected with a gear, the gear is mounted on a motor shaft of the motor, and the motor is mounted on the base.

[0010] Preferably, a cover plate is installed at the upper end of the hopper, and the cover plate is connected to an external negative pressure suction device through a feed pipe thereon.

[0011] Preferably, a preheating pipe for the heat transfer oil to flow is provided inside the side wall of the hopper, and the preheating pipe is in a spiral shape.

[0012] The beneficial effects of the present invention are: The present invention achieves that the top cover drives the feeding part to move during the rotation process through the cooperation between the vortex ring, the feeding part and the top cover, so that the feeding part can continuously feed the rubber powder into the interior of the vortex ring, so that the rubber powder can be flattened on the upper side of the base and transported along the trajectory of the vortex ring. At this time, the heat transfer oil in the heating tank will heat the rubber powder on the base. Since the rubber powder is flattened and transported on the base, it can be ensured that the rubber powder is heated evenly.

[0013] The present invention realizes that the disturbance rod and the connecting rod can cooperate with each other when the hopper rotates, so as to shear and destroy the rubber powder agglomerated in the hopper, prevent the agglomerated rubber powder from clogging the entrance of the vortex ring, and at the same time, the disturbance rod can stir the rubber powder inside the hopper, so that the rubber powder inside the hopper can better enter between the top cover and the base.

[0014] The present invention provides a cover plate at the upper end of the hopper, and a feed pipe is provided on the cover plate. The feed pipe is connected to an external negative pressure suction device, and rubber powder can be continuously added to the interior of the hopper through the external negative pressure suction device. At the same time, air is also sucked into the interior of the hopper, and is heated by the heating oil in the preheating pipeline, and finally enters the interior of the channel formed by the vortex ring, which can not only reduce the friction force of the rubber powder when it flows, but also promote its movement, so that the rubber powder flows better, and after the air is preheated, it is fully in contact with the rubber powder, which can further improve the heating effect on the rubber powder.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The present invention provides a waste rubber powder desulfurization and plasticization device, such as Figures 1 to 8 shown.

[0027] Embodiment 1: A waste rubber powder desulfurization and plasticization device comprises a base 1, the upper side of the base 1 is fixedly connected with a vortex ring 2, the interior of the base 1 is provided with a heating tank 8 for heat transfer oil to flow, the shape of the heating tank 8 is vortex-shaped, and one end of the heating tank 8 is provided with an inlet pipe, and the other end is provided with a discharge pipe, the heat transfer oil enters the interior of the heating tank 8 through the inlet pipe, and is discharged through the discharge pipe.

[0028] A top cover 3 is rotatably installed above the vortex ring 2, and a gear ring 10 is fixedly connected to the top cover 3. The gear ring 10 is meshed with a gear 11, and the gear 11 is fixedly installed on the motor shaft of the motor 12. The motor 12 is installed in a fixed frame provided on the base 1, and a top plate is provided above the fixed frame. The top plate can protect the motor 12, the gear 11 and the gear ring 10, and the rotation of the motor shaft of the motor 12 can drive the top cover 3 to rotate.

[0029] A hopper 4 is fixedly connected to the upper side of the top cover 3, and the axis of the hopper 4 coincides with the axis of the base 1. A feeding portion is provided inside the hopper 4, and the feeding portion can push the rubber powder dropped onto the base 1 through the hopper 4 into the interior of the vortex ring 2, so that the rubber powder inside the hopper 4 can continuously enter the interior of the vortex ring 2 and be flattened. At this time, the heat transfer oil flowing inside the heating tank 8 can heat the flattened rubber powder. Since the rubber powder is flattened, the rubber powder is heated more evenly.

[0030] The feeding part includes an elastic rod 6, which is located on the upper side of the base 1 and is connected to the inner wall of the hopper 4 through a connecting rod 7. The elastic rod 6 contacts the side of the vortex ring 2 under its own elastic force, and the motor 12 drives the top cover 3 along the Figure 4 The top cover 3 rotates clockwise in the direction shown. The top cover 3 drives the hopper 4 to rotate during the clockwise rotation, thereby driving the elastic rod 6 to rotate clockwise, and then the elastic rod 6 can continuously push the rubber powder on the base 1 into the interior of the vortex ring 2.

[0031] At the same time, a guide block 9 is fixedly connected to the center position of the upper side of the base 1. The shape of the guide block 9 is conical, and one end of the elastic rod 6 and the connecting rod 7 connected to each other fits with the side of the cone. The guide block 9 can cooperate with the elastic rod 6 to completely push the rubber powder located directly below the hopper 4 into the interior of the vortex ring 2, and no rubber powder will remain directly below the hopper 4.

[0032] Embodiment 2: On the basis of Example 1, in order to make the rubber powder inside the hopper 4 fall onto the base 1 better, a disturbance rod 5 is fixedly connected to the guide block 9, the disturbance rod 5 has the same angle as the conical surface of the guide block 9, and the lateral distance between the upper end and the lower end of the disturbance rod 5 is adapted to the inner diameter of the hopper 4. In the process of the top cover 3 driving the hopper 4 to rotate, the rubber powder inside the hopper 4 will rotate synchronously. At this time, the disturbance rod 5 can stir the rubber powder inside the hopper 4, so that the rubber powder inside the hopper 4 can fall downward better.

[0033] The connecting rod 7 is also set to be inclined, and the angle of the connecting rod 7 is adapted to the angle of the disturbance rod 5. The corresponding side surfaces of the connecting rod 7 and the disturbance rod 5 are set to cooperate with each other. During the rotation of the hopper 4, the connecting rod 7 rotates synchronously with the hopper 4. During the rotation, the connecting rod 7 can cooperate with the disturbance rod 5 to shear and destroy the agglomerated rubber powder, thereby preventing the agglomerated rubber powder from entering the interior of the vortex ring 2 and affecting the desulfurization and plasticization effect of the rubber powder.

[0034] The height of the upper end of the connecting rod 7 is lower than the height of the coincidence point of the disturbance rod 5 and the axis of the hopper 4, so that the connecting rod 7 will not interfere with the disturbance rod 5 during the rotation process.

[0035] Embodiment three: On the basis of the second embodiment, in order to make the rubber powder move better, a cover plate 13 is arranged at the upper end of the hopper 4, and a feed pipe 14 is arranged on the cover plate 13. The feed pipe 14 is connected to the external negative pressure suction device. The external negative pressure suction device can directly draw the rubber powder into the inside of the feed pipe 14, and the negative pressure device can draw the external air into the inside of the feed pipe 14 and into the inside of the hopper 4 while drawing the rubber powder into the inside of the feed pipe 14. A spiral preheating pipe 15 is arranged inside the side wall of the hopper 4, and heat transfer oil also flows inside the preheating pipe 15. The lower end of the preheating pipe 15 is the inlet of the heat transfer oil, and the upper end is the outlet of the heat transfer oil. When the air and rubber powder pass through the hopper 4, they will be preheated in advance and then enter the vortex ring 2, so that the rubber powder can be better heated inside the vortex ring. The temperature of the heat transfer oil flowing inside the preheating pipe 15 is lower than the temperature of the heat transfer oil flowing inside the heating tank 8, which can prevent the rubber powder from being plasticized inside the preheating pipe 15 and affecting subsequent transmission. After the air enters the hopper 4, it enters the vortex ring 2 together with the rubber powder. The air moves with the rubber powder, which can not only increase the distance between the rubber powders and reduce the friction between the rubber powders, but also promote the movement of the rubber powder, so that the rubber powder can move better inside the vortex ring 2.

[0036] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
