Description

Technical Field

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

[0002] As an important industrial material, rubber is widely used in industries such as tires, shoes, and construction. However, the mixing process of rubber is a complex and time-consuming process, which requires the addition of various types of additives to assist in the mixing of rubber. In the early stage of mixing, the addition of liquid additives such as operating oil and plasticizer oil is essential. They can reduce the viscosity of rubber, increase its plasticity, and make rubber easier to mix with other additives. In addition, the addition of reinforcing fillers is also a key step in the mixing process, which can improve the strength and wear resistance of rubber.

[0003] However, there are many problems with the traditional rubber mixing method. In the early stage of mixing, due to the poor flexibility of rubber, it is difficult to fully mix and disperse the granular reinforcing filler with the rubber when it is added. This causes the mixing process to take a long time, seriously affecting production efficiency. In order to solve this problem, in the early stage of rubber mixing, a mixing device is used to mix the reinforcing filler with liquid additives such as operating oil and plasticizing oil to obtain a mixed additive. Then, the liquid additive mixed with the reinforcing filler is added to the rubber for mixing, so that the granular reinforcing filler can be dispersed to the greatest extent and mixed with the rubber.

[0004] However, in actual operation, during the processing and later storage stages of granular reinforcing fillers, some granular materials will combine together to form lumps. When these lumps are directly added to liquid additives, it is difficult to fully mix with the liquid additives and requires long-term stirring. This not only affects production efficiency, but may also lead to unstable quality of rubber products. Therefore, how to improve the mixing effect of rubber additives and shorten the mixing time has become an urgent problem to be solved in the rubber industry. Summary of the invention

DETAILED DESCRIPTION

[0021] 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. As long as the effects of the present invention can be exerted, various changes can be made to the implementation scheme.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0023] Reference Figure 1-Figure 14 A rubber additive processing device and a processing method are described.

[0024] First, this embodiment discloses a rubber additive processing device, such as Figure 1 and Figure 2 As shown, a mixing device for liquid rubber additives and granular rubber additives is shown, which comprises a mixing tank 1, on which a stirrer 2 is arranged, and the stirrer 2 comprises a motor, a reducer and a main shaft.

[0025] like Figure 1-Figure 3 As shown, the two sides of the mixing tank 1 of this embodiment are respectively provided with a liquid feeding device 3 and a solid feeding device 4. The liquid feeding device 3 provides liquid additives such as operating oil and plasticizer oil into the mixing tank 1, and the solid feeding device 4 provides granular solid additives such as carbon black and calcium carbonate into the mixing tank 1. The solid additives and the liquid additives are mixed into one to obtain a solid-liquid mixture additive. The solid-liquid mixture additive is added in the early stage of rubber mixing, so that the additives added in this stage can better combine with the rubber, reduce the viscosity of the rubber, and improve the plasticity, so as to be fully mixed and dispersed with the rubber. It should be noted that: in the top view projection of the mixing tank 1, the agitator 2 is located on the side of the liquid feeding device 3 and the solid feeding device 4.

[0026] like Figure 4 As shown, in order to improve the stirring and mixing effect, the main shaft portion of the agitator 2 passes through the mixing tank 1 and is provided with a first stirring blade 5 and a second stirring blade 6 in the axial direction. The first stirring blade 5 is located above the solid-liquid mixture additive, and the second stirring blade 6 is located below the solid-liquid mixture additive.

[0027] Furthermore, an upper bending plate 7 is formed by bending at the top of the first stirring blade 5, and an angle α is formed between the upper bending plate 7 and the first stirring blade 5, 165°>a>150°. A lower bending plate 8 is formed by bending at the bottom of the second stirring blade 6, and an angle β is formed between the lower bending plate 8 and the second stirring blade 6, 165°>β>150°. When the main shaft rotates to drive the first stirring blade 5 and the second stirring blade 6 to mix the solid-liquid mixture additive, the upper bending plate 7 presses the granular solid additive floating on the surface of the solid-liquid mixture additive into the solid-liquid mixture additive, and the lower bending plate 8 rolls up the granular solid additive precipitated at the bottom to prevent precipitation.

[0028] Specifically, Figure 5 and Figure 6 As shown, the liquid feeding device 3 includes a box body 31, a liquid flow plate 32 and a plurality of liquid spray heads 37. The box body 31 includes a liquid feeding end and a liquid discharge end inserted into the mixing tank 1, and the plurality of liquid spray heads 37 are fixed on the liquid feeding end. A first fixing plate is provided on the box body 31, and the first fixing plate is fixed on the mixing tank 1, so that the box body 31 is positioned on the mixing tank 1.

[0029] The liquid flow plate 32 is arranged at the bottom of the box body 31; the liquid flow plate 32 forms a liquid flow first section 321, a liquid flow middle section 322 and a liquid flow tail section 323 in sequence along the direction from the liquid spray head 37 to the liquid discharge end.

[0030] Furthermore, a liquid spraying chamber 34 is provided in the box body 31, and an arc-shaped liquid receiving plate 36 is provided at the wall of the box body 31 corresponding to the liquid spraying head 37 in the liquid spraying chamber 34, and the bottom of the arc-shaped liquid receiving plate 36 is suspended above the middle section 322 of the liquid flow, and an inner baffle 35 is provided in the liquid spraying chamber 34 and between the liquid spraying head 37 and the arc-shaped liquid receiving plate 36; The extension line of the liquid ejecting head 37 forms an angle a with the surface of the inner baffle 35, wherein 160>a>120.

[0031] During implementation, multiple spray heads 37 are fixed at the liquid feeding end; multiple liquid additives are sprayed out through multiple spray heads 37 and act on the inner baffle 35. When the liquid contacts the inner baffle 35, a sputtering effect is generated, so that the multiple liquid additives are dispersed into smaller droplets, and a mixing effect is achieved when they are splashed and dripped and then merged.

[0032] The inner baffle plate 35 is tiltedly arranged in the liquid spraying chamber 34 , with the top of the inner baffle plate 35 arranged toward the top of the arc of the arc-shaped liquid receiving plate 36 , and the bottom of the inner baffle plate 35 arranged toward the liquid flow first section 321 .

[0033] During the implementation process, after the splashing of multiple liquids, a part of the liquid drips downward along the inner baffle 35 and gathers at the first section 321 of the liquid flow plate 32, and flows toward the middle section 322 of the liquid flow; the other part of the liquid impacts the arc-shaped liquid receiving plate 36 for pre-mixing, and the pre-mixed liquid drips along the bottom of the arc-shaped liquid receiving plate 36 to the middle section 322 of the liquid flow, and flows with the flowing liquid at the tail section 323 of the liquid flow for secondary mixing.

[0034] like Figure 7 and Figure 8 As shown, the solid feeding device 4 includes a processing box 43 and a screen 45. The screen 45 is fixed in the processing box 43; the granular material entering the storage box 41 falls on the screen 45 and flows out from the discharge nozzle 42 after being screened. A second fixing plate is provided on the processing box 43, and the second fixing plate is fixed on the mixing tank 1, so that the processing box 43 is positioned on the mixing tank 1.

[0035] Furthermore, a material storage box 41 and a discharge nozzle 42 inserted into the mixing tank 1 are provided on the processing box 43; a discharge cavity 44 is connected between the processing box 43 and the discharge nozzle 42, and a first nozzle 46 is provided in the discharge cavity 44 and is arranged toward the discharge nozzle 42.

[0036] The granular additive falls from the storage box 41 onto the screen 45 , and the screened particles slide into the discharge cavity 44 .

[0037] The discharge nozzle 42 includes an opening 421, and the upper and lower distances of the inner cavity of the discharge nozzle 42 gradually decrease from the discharge cavity 44 to the opening 421. At this time, the airflow is affected by the gradually decreasing cavity and the wind speed increases, so that the ejected airflow entrains the particulate material (particulate solid additive) and is ejected from the opening 421; the opening 421 includes a protrusion 422 and a depression 423 connected in sequence, and the protrusion 422 and the depression 423 form a continuously curved surface. The first nozzle 46 ejects gas to eject the particulate additive through the continuously curved opening 421. The form of the curved surface can make the particulate material present different lifts when it is ejected. The lift of the particulate material ejected from the protrusion 422 is farther than that from the depression 423, so that the particulate material can be evenly distributed when it is ejected.

[0038] In the specific implementation, during the processing stage and the later storage stage, some of the granular materials will combine together to form agglomerates. To solve the agglomeration problem, Fig.10 As shown, a table panel 47 is arranged on one end of the screen 45 close to the discharge cavity 44, and an air supply pipe 410 is connected to the table panel 47, and the air supply pipe 410 is connected to a gas compressor. The table panel 47 is staggered with through holes, and a decomposition component 49 is arranged in the through holes to decompose the agglomerated materials into bulk particles and then fall into the discharge cavity 44.

[0039] In one embodiment, if Fig.11 and Fig.12As shown, the decomposition assembly 49 includes an outer ring 491 and an inner disk 492 disposed inside the outer ring 491, and a plurality of second nozzles 495. The outer ring 491 is fixed in the through hole; an annular air pipe 498 communicating with the air supply pipe 410 is disposed inside the outer ring 491; During installation, the bottom of the inner disk 492 is fixedly connected to the bottom of the outer ring 491 through the connecting beam 493, so that the inner disk 492 is stabilized inside the outer ring 491; it should be noted that the inner disk 492 and the outer ring 491 are eccentrically arranged, so that a gap groove 494 is formed between the inner disk 492 and the outer ring 491, and the gap groove 494 is an eccentric ring shape. Among them, in the gap groove 494, the maximum gap spacing between the inner disk 492 and the outer ring 491 is A, the minimum gap is B, and A>B, and the spacing gradually increases from B to A.

[0040] When installing, the plurality of second nozzles 495 need to be circumferentially distributed on the inner side wall of the outer ring 491, and each second nozzle 495 is connected to the annular air pipe 498, so that the strong airflow generated by the gas compressor can pass through the air supply pipe 410 and the annular air pipe 498 and then be ejected through the second nozzle 495; One end of a beam arm 496 is rotatably connected to the inner disk 492, and the other end of the beam arm 496 is connected to a shift plate 497; wherein, the second nozzle 495 ejects gas to act on the shift plate 497, driving the beam arm 496 to rotate the shift plate 497 in the gap groove 494 with the center of the outer ring 491 as the center of the circle.

[0041] During implementation, the agglomerated particles slide down on the screen 45 to the table panel 47 and fall into the gap groove 494. The second nozzle 495 sprays gas to act on the disc 4972. When the paddle plate 497 rotates in the gap groove 494, the agglomerated particles are driven to move in the eccentric ring-shaped gap groove 494. The agglomerated particles are squeezed by the paddle plate 497 and the gradually decreasing spacing of the gap groove 494, and the agglomerated particles are converted into loose particles.

[0042] In this embodiment, if Fig.13As shown, the dial plate 497 includes a disc 4972, a dial pin 4971 and a lower dial plate 4973. The disc 4972 is fixedly connected to the beam arm 496, and the center of the disc 4972 is inwardly recessed to form a sink, and the sink part fits on the agglomerated particles and moves in the gap groove 494. The dial pin 4971 is fixed on the top of the disc 4972. When the dial plate 497 rotates, the dial pin 4971 first contacts the agglomerated particles to break the agglomerated particles. The lower plate 4973 is fixed at the bottom of the disc-shaped member 4972, and a guide groove 4974 connected to the trough is formed on the inner side of the lower plate 4973; it should be noted that the second nozzle 495 sprays gas to act on the trough, and the trough guides the gas to the guide groove 4974, and the guide groove 4974 guides the gas downward, so that the gas enters the discharge chamber 44, and blows the particles dropped in the processing box 43 into the discharge chamber 44.

[0043] In one embodiment, if Fig.10 and Fig.14 As shown, the decomposition components 49 are staggered on the table panel 47, specifically, two rows of staggered decomposition components 49 are arranged, and a material stopper 48 is arranged at the rear side of the table panel 47 and between two adjacent decomposition components 49. During operation, the rolling agglomerated particles are first decomposed by the decomposition components 49 in the first row, and some agglomerated particles pass through the interval between two adjacent decomposition components 49 in the first row and enter the decomposition components 49 in the second row to be decomposed, while some agglomerated particles will pass through the decomposition components 49 in the first row and jump backwards. At this time, these agglomerated particles will hit the material stopper 48 and be distributed to the decomposition components 49 on both sides.

[0044] Specifically, the material blocking body 48 includes a bottom plate 481, a back plate 487 of a cone 483, and a top baffle 482. The bottom plate 481 is fixed on the table panel 47; the cone 483 is fixed on the bottom plate 481, and an intermediate baffle 484 is provided in the middle of the front of the cone 483, which divides the cone 483 into a first bevel surface 485 and a second bevel surface 486 arranged on the left and right, and the first bevel surface 485 and the second bevel surface 486 and the intermediate baffle 484 have a smooth transition; the back plate 487 is fixed on the back of the cone 483; and the top baffle 482 is fixed on the top of the cone 483. During implementation, the agglomerated particles collide with the first bevel surface 485 or the second bevel surface 486, and are guided to the adjacent decomposition component 49 along the bevel surface. The back plate 487 and the top baffle 482 prevent the agglomerated particles from moving backward, ensuring that the agglomerated particles can be guided to the adjacent decomposition component 49 along the bevel surface.

[0045] It should be further explained that the liquid feeding device 3 and the solid feeding device 4 are arranged opposite to each other, and the discharge end of the solid feeding device 4 is located above the discharge end of the liquid feeding device 3; an upper opening 33 is opened on the top of the liquid discharge end of the box body 31, so that the granular material flowing out of the discharge nozzle 42 falls to the liquid tail section 323 on the liquid flow plate 32, so that the granular additive is evenly distributed on the flowing liquid additive to form a solid-liquid premixture, and then enters the mixing tank 1. The solid-liquid mixture formed by the liquid additive entraining the granular additive falls into the mixing tank 1, and the agitator 2 works to stir and mix the solid-liquid premixture through the first stirring blade 5 and the second stirring blade 6.

[0046] Secondly, this embodiment also discloses a rubber additive processing method, which uses the above-mentioned rubber additive processing device and includes the following steps: S1, multiple liquid additives are sprayed onto the inner baffle 35 through multiple spray heads 37 to generate splashes; S2, part of the liquid after the sputtering drips downward along the inner baffle 35 and gathers at the first section 321 of the liquid flow plate 32, and flows toward the middle section 322 of the liquid flow; S3, another part of the liquid after sputtering impacts on the arc-shaped liquid receiving plate 36, and is premixed during the sputtering and downward flow process to obtain a premixed mixture, and the premixed mixture drips along the bottom of the arc-shaped liquid receiving plate 36 to the middle section of the liquid flow, and flows on the liquid tail section 323 to be secondary mixed with the flowing liquid to obtain a secondary premixed mixture; S4, the granular additive falls from the storage box 41 onto the screen 45, and the screened particles slide into the discharge cavity 44; the agglomerated particles slide down on the screen 45 onto the table panel 47 and fall into the gap groove 494; S5, the second jet head 495 sprays gas to act on the disc-shaped member, causing the beam arm 496 to rotate with the center of the outer ring 491 as the center of the circle, and the paddle 497 rotates in the gap groove 494 to break the agglomerated particle additives, and the broken particle additives fall into the discharge cavity 44; S6, the first jet head 46 sprays gas to spray the particle additive along the continuously curved opening 421 and drop it onto the liquid tail section 323, so that the particle additive is evenly distributed on the flowing secondary premixture to form a solid-liquid premixture; S7 , the solid-liquid premix falls into the mixing tank 1 , and the stirrer 2 stirs and mixes the solid-liquid premix through the first stirring blade 5 and the second stirring blade 6 .

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
