Description

Technical Field

[0001] The present invention relates to the technical field of rubber raw material processing, and specifically relates to a rubber raw material mixer with good mixing effect. Background Technique

[0002] Mixing is a process of using a rubber mixer to mix raw rubber or plasticated raw rubber with compounding agents into a mixed rubber, and it is the most important production process in rubber processing. Essentially, it is a process of uniformly dispersing compounding agents in raw rubber. Granular compounding agents are in the dispersed phase, and raw rubber is in the continuous phase. Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformations under very small external forces, and can return to its original state after the external force is removed. Rubber belongs to a completely amorphous polymer. Its glass transition temperature is low, and its molecular weight is often very large, greater than several hundred thousand. During the process of rubber processing, it is often necessary to mix rubber raw materials, so a rubber raw material mixing device needs to be set up.

[0003] Currently, when the existing rubber raw materials are mixed, it is necessary to heat them to improve the plasticity and fluidity of the rubber and promote the dispersion and mixing of compounding agents. However, the gas after heating the existing rubber mixer is mostly directly discharged from the mixer for treatment and emission. Subsequently, the heat in the discharged flue gas cannot be effectively utilized, resulting in a certain waste of resources. In addition, the flue gas generated during the rubber mixing process is inconvenient to treat and cannot be quickly treated. Finally, the existing mixers mostly mix rubber and compounding agents through stirring rods, and their stirring devices are mostly fixedly installed. Subsequently, the rubber raw materials in the corner parts of the mixing barrel cannot be effectively mixed and stirred. For this reason, we have proposed a rubber raw material mixer with good mixing effect. Summary of the Invention

For the rubber raw material mixer with good mixing effect, through the cooperation of the water tank, exhaust holes, exhaust fan, air collecting hood, air distribution plate and aeration nozzles, during the mixing process, the exhaust fan can introduce the flue gas generated by heating during mixing into the air collecting hood through the exhaust holes. Subsequently, after the flue gas enters the air distribution plate, it is discharged through the aeration nozzles. Then, the flue gas can be washed and filtered by the water in the water tank. After the flue gas is washed by water, some organic waste gases that can dissolve in water, such as sulfides, benzene, xylene, etc., can be effectively removed. At the same time, the heat in the flue gas can heat the water in the water tank. Subsequently, through the cooperation of the storage tank, heat exchange pipe, water pump, feeding port, first motor and first stirring rod, the water heated in the water tank can be introduced into the heat exchange pipe by the water pump to preheat the rubber raw materials to be mixed and processed stored in the storage tank, thereby shortening the heating time for the subsequent mixing of the rubber raw materials in the mixing box, and thus improving its overall mixing efficiency.

[0015] 2. The rubber raw material kneader with good mixing effect, through the cooperation of the rotating shaft, disc, connecting rod, transmission gear, chain, second motor, driving bevel gear, sliding box, transmission shaft, first transmission bevel gear, second transmission bevel gear, reciprocating screw rod, driven bevel gear, sleeve block, limiting groove, mounting plate, third motor and second stirring rod, when mixing rubber raw materials, after starting the second motor, it can drive a transmission gear to rotate, and the transmission gear drives another transmission gear to rotate through the chain, so as to drive the disc to rotate through the rotating shaft and then drive the kneading box to move up and down reciprocally through the connecting rod. At the same time, the driving bevel gear meshes with the first transmission bevel gear, and then drives the transmission shaft to rotate. After the transmission passes through the second transmission bevel gear meshing with the driven bevel gear, it drives the reciprocating screw rod to rotate, and then can drive the sleeve block to move left and right reciprocally through the thread. Thus, after starting the third motor to drive the second stirring rod to rotate, it can realize the left and right reciprocating mixing of the rubber raw materials in the kneading box, and at the same time cooperate with the up and down reciprocating movement of the kneading box to mix the rubber raw materials, effectively improving the mixing effect.

[0023] The interior of the kneading box 28 is provided with electric heating tubes 54. Limit plates 51 are fixedly installed on both sides of the kneading box 28. Guide grooves 52 are opened on both sides inside the outer shell 1. Guide rods 53 are fixedly installed inside the guide grooves 52. The limit plates 51 are slidably connected to the guide rods 53.

Similarly, it can also take away the heat generated by the electric heating tubes 54 and introduce it into the water tank 2 to heat the water inside, improving the utilization rate of resources and avoiding waste of resources.

[0024] In summary, for the rubber material mixer with good mixing effect, when in use, at the beginning of mixing, after starting the second motor 36, a driving gear 33 can be driven to rotate. The driving gear 33 drives another driving gear 33 to rotate through a chain 34, so as to drive a disc 31 to rotate through a rotating shaft 30 and then drive a mixing box 28 to move up and down reciprocally through a connecting rod 32. At the same time, a driving bevel gear 37 meshes with a first transmission bevel gear 40, and then drives a transmission shaft 39 to rotate. The transmission drives a reciprocating lead screw 42 to rotate after a second transmission bevel gear 41 meshes with a driven bevel gear 43, and then can drive a sleeve block 44 to move left and right reciprocally through threads. Thus, after starting the third motor 47 to drive a second stirring rod 48 to rotate, the rubber material in the mixing box 28 can be mixed left and right reciprocally, and at the same time, it cooperates with the up and down reciprocating movement of the mixing box 28 to mix the rubber material, effectively improving the mixing effect. During the mixing process, through an exhaust fan 4, the flue gas generated by heating during mixing can be introduced into a gas collecting hood 5 through an exhaust hole 3. Then, after the flue gas enters a gas distribution plate 6, it is discharged through an aeration nozzle 7. Then, the water in a water tank 2 can be used to clean and filter the flue gas. After the flue gas is washed with water, some organic waste gases that can be dissolved in water, such as sulfides, benzene, xylene, etc., can be effectively removed. At the same time, the heat in the flue gas can heat the water in the water tank 2. Through a water pump 10, the heated water in the water tank 2 can be introduced into a heat exchange tube 9 to preheat the rubber material to be mixed and processed stored in a storage tank 8. When preheating, after starting a first motor 12, a first stirring rod 13 can be driven to rotate. The first stirring rod 13 stirs the rubber material to be processed in the storage tank 8 to improve its overall preheating effect, and then shortens the heating time for the rubber material to be subsequently added to the mixing box 28 for mixing, thereby improving its overall mixing efficiency. Finally, when it is necessary to disassemble and replace an activated carbon filter plate 16, by pulling a side pull plate 26, a pin 21 is pulled out from a pin hole 22 to release the limit on a positioning block 19. Then, the positioning block 19 and the activated carbon filter plate 16 can be disassembled from a T-shaped groove 18, which is convenient for its replacement and cleaning.
