Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kneaders, in particular to a continuous kneader and a kneading method. BACKGROUND

[0002] A kneader is an ideal device for kneading, mixing, vulcanizing and polymerizing of high-viscosity and elastoplastic materials. The kneader can be used for producing silicone rubber, sealant, hot melt adhesive, food gum base, pharmaceutical preparations, etc. The kneader is a special mixing and stirring device, which usually adopts a differential speed type arrangement with side-by-side tangential arrangement, i.e. one stirring paddle has a high speed and the other stirring paddle has a low speed, so as to generate shear force. Different paddle speeds enable the mixed materials to be rapidly sheared, so that the materials can be uniformly mixed. When the two stirring paddles are started or idled, they will rub against each other or the cylinder wall, which is easy to generate heavy metal chips. In addition, the materials may be mixed with metal impurities during feeding. If the kneading is performed without screening, the metal substances will damage the built-in parts of the kneader and affect the effect of the finished product, resulting in low material purity. After kneading, the material is in a viscous state, and it is very difficult to screen out the metal impurities at this time.

[0003] In the prior art, a multi-screw discharging kneader with publication number "CN214726331U" is disclosed, which includes a stirring box body, an operation box, a driving transmission device and a discharging device. The driving transmission device is arranged on one side of the stirring box body, and the discharging device and a discharging motor are arranged at the bottom of the stirring box body. The main transmission device is controlled by the operation box. The upper stirring blade and the lower stirring blade with opposite rotation directions are arranged in the stirring box body. The discharging device includes a discharging pipe, the upper part of the discharging pipe is communicated with the bottom of the stirring box body, the output end of the discharging motor is connected with a discharging screw, the discharging screw is arranged in the discharging pipe, and the discharging end of the discharging pipe is provided with a discharging disc. A plurality of discharging holes with different specifications are arranged on the discharging disc. The multi-screw discharging kneader can mix materials more uniformly and completely, and realize continuous production and improve production efficiency without stopping production for discharging. The kneader can discharge different shapes of materials according to needs, realizes the function of one-time discharging of the kneader, and improves the discharging speed.

[0004] However, the above-mentioned device only has a basic material kneading function, and cannot process heavy metal chips generated by friction during use, heavy metal chips carried in the materials, etc. Not only is it easy to damage the built-in parts of the kneader, but also affects the kneading state of the materials and reduces the quality of the finished product.
