Description

Technical Field

[0001] The invention relates to the technical field of waste rubber processing, and in particular to a novel continuous waste rubber cracking device and method. Background Art

[0002] The pyrolysis equipment uses waste rubber as raw material. Under the catalysis and suitable temperature in the reactor, the straight-chain macromolecular structure of the rubber is broken through thermal cracking reaction and catalytic cracking reaction to achieve the conversion of high-molecular rubber composed of hydrocarbon elements into low-molecular fuel. However, in the prior art, most of the waste rubber tires are directly reacted in the pyrolysis bin after being crushed, which cannot achieve the purpose of uniform feeding of the crushed tires to ensure a stable proportion of raw materials in the pyrolysis bin, and the rubber raw materials cannot be heated uniformly, which affects the effect and efficiency of the pyrolysis and makes it less applicable.

[0003] In order to solve the above problems, a Chinese patent with announcement number CN111978973B proposes an environmentally friendly waste rubber tire cracking device, in which a motor is operated so that a driving wheel can drive a driven wheel to rotate through a belt, and the driven wheel can drive a driven gear and a connecting shaft to rotate through a driving gear, and the connecting shaft can drive a spiral blade and a plurality of stirring rods to rotate. A single motor is used to complete multiple processes of raw material crushing, uniform feeding and stirring and mixing, thereby reducing the use of electrical equipment, reducing processing costs, and improving the effect and efficiency of the cracking reaction.

[0004] Another disadvantage is that the connecting shaft connects the spiral blades and multiple stirring rods at the same time, resulting in the spiral blades and the stirring rods can only rotate at the same speed. However, the rotation speed of the spiral blades is usually low when the material is evenly fed. The stirring rods rotate at the same low speed as the spiral blades, which will lead to poor stirring and mixing effects, thereby affecting the subsequent cracking reaction and restricting the effect and efficiency of the cracking reaction.

[0042] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0043] By arranging the spiral blade 15 and the stirring rod 16 on the second rotating tube 10 and the second rotating shaft 9 respectively, and transmitting them through the first rotating tube 6 and the first rotating shaft 7 respectively, and then arranging a differential assembly between the first rotating tube 6 and the first rotating shaft 7, the problem in the prior art that when a single motor 3 is used for driving, the spiral blade 15 and the stirring rod 16 can only rotate at the same speed, resulting in the stirring rod 16 using the same low speed rotation as the spiral blade 15, which leads to poor stirring and mixing effect, thereby improving the effect and efficiency of the cracking reaction.

[0044] Embodiment 2: Although the rotation speed of the stirring rod 16 in the above embodiment is improved, in the actual waste rubber cracking process, it is necessary to select an appropriate stirring speed according to factors such as the different stages of the cracking process, reaction temperature, and material properties; therefore, the embodiment of the present application is optimized on the basis of the above embodiment.

A novel continuous waste rubber cracking device cracking method as claimed in claims 1 to 9, characterized in that: The method comprises: step S1, pretreatment: first, the staff needs to sort and classify the waste rubber and place the waste rubber to be cracked into the feed port; Step S2, crushing process: when the waste rubber is placed on the crushing roller (2), the motor (3) is started, and the motor (3) drives the crushing roller (2) to rotate so as to crush the waste rubber; Step S3, uniform material feeding: the motor (3) drives the driving wheel (4) to rotate, the driving wheel (4) drives the driven wheel (5) to rotate, the driven wheel (5) drives the first rotating tube (6) to rotate, the first rotating tube (6) drives the second rotating tube (10) to rotate through the outer first bevel gear (11) and the outer second bevel gear (12), and the second rotating tube (10) drives the spiral blade (15) to rotate, so that the raw material is uniformly transported to the cracking chamber; Step S4, cracking reaction: after the raw material is transported to the cracking chamber, it is heated and cracked, and at the same time, the stirring rod (16) rotates to stir the raw material to promote the cracking reaction; Step S5, stirring speed adjustment: by adjusting the length of the hydraulic rod (29), the radius of the first transmission wheel (21) and the second transmission wheel (22) is changed, thereby changing the transmission ratio, so that the rotation speed of the first rotating shaft (7) is changed, the first rotating shaft (7) drives the second rotating shaft (9) to rotate, and the second rotating shaft (9) drives the stirring rod (16) to rotate to stir the material in the cracking chamber, thereby changing the stirring speed to adapt it to the current cracking state.
