Abstract:
[Object] To provide a mounting configuration of a thermocouple temperature detector on a kneading tank, in which a temperature detection end of the thermocouple temperature detector mounted on a kneader for high viscosity material can perform a real time temperature measurement and a mechanical load applied on the temperature detection end by flow of the kneading material is minimized as possible. [Solution] A heat sensing section 18 in a hemispherical shape on the distal end of a protective inner tube 17 which houses a thermocouple element 12 of a thermocouple temperature detector 10 is mounted on a kneading tank 1 for kneading a high viscosity kneading material so as to protrude from the distal end of a protective chip 16 which protrudes into the kneading tank. A protrusion proximal end 16a of the protective chip which protrudes into the kneading tank is formed to have an outer diameter of 2 to 3 times as large as that of the protective inner tube and a protruding length h which protrudes into the kneading tank having the same length as the difference between a radius of the protrusion proximal end of the protective chip and a radius of the protective inner tube, and an outer peripheral surface of the shoulder 16b of the protective chip which extends from the protrusion proximal end of the protective chip to a position which is in contact with the outer periphery of the protective inner tube is formed in a convex curvature surface having a radius which corresponds to a difference between the radius of the protrusion proximal end of the protective chip and the radius of the protective inner tube.
Abstract:
A kneading device uniformly kneads materials to be kneaded while efficiently and quickly kneading the materials to be kneaded. A kneading device includes a kneading chamber accommodating materials to be kneaded and a pair of rotors (10) . The pair of rotors (10) is rotated in the kneading chamber and kneads the materials to be kneaded by a plurality of kneading blades (20). The plurality of kneading blades (20) in each rotor (10) is composed only of inclined blades inclined to the same direction in a rotational direction (R) of the rotor (10) with respect to an axial direction (X) of the rotor (10) when the rotor (10) is developed into a planar state. The rotor (10) has bent blades (30, 40) which are bent at bent portions (31, 41) to change tilt angles (E, F) with respect to the axial direction (X) of the rotor (10) in the plurality of kneading blades (20).

Abstract:
A hermetically closed kneader comprising a case member (1) having a cocoon-section closed chamber (2) therein, and a pair of rotors (3, 4) disposed in parallel with each other in the chamber (2) and adapted to be rotated in the opposite directions, each of the rollers (3, 4) having three long blades (18, 19, 20) extending helically around the axis of a roller and spaced from one another in circumferential direction at an equal angle, the axes (17a, 17b) of the rotors (3, 4) being spaced from each other by such a distance L that prevents the long blades (18, 19, 20) of different rotors from being engaged with one another, a cross-sectional shape of the portions of the rotors which include the long blades (18, 19, 20) being set so that a cross section of the rotors becomes substantially triangular, or so that a reaction surface portion (22) of a rear surface (26) with respect to the rotational direction in the cross section of the rotors includes a straight line having as a starting point an end (18a) of a tip (21) of a long blade, or so that the rear surface (26) with respect to the rotational direction in the cross section of the rotors comprises a curved surface similar to one smooth concave or convex or flat surface, the relation between a maximum diameter (Dr) of the cross section of the rotors and a minimum diameter (Dd) thereof being set in the range of 0.5
Abstract:
An internal batch mixing machine (20) includes a mixing chamber and oppositely driven first and second rotors (22, 24). The first rotor has a pair of lobes located in its first and third quadrants (96, 98; 100', 102'), while the second rotor has a pair of lobes (120, 122; 124', 126') located in its second and fourth quadrants. One of the lobes (96, 98) of each pair is longer than the other, and extends downstream at an acute co-helix angle toward the other lobe (98, 116'). The leading end of the long lobe is near one end of its rotor, and the short lobe is at the other end. Material adjacent the longer lobe are pushed away from its end and toward the other end of that rotor. Additionally, the trailing ends of each pair of lobes forms a space which causes confluent material to be squeezed between the trailing ends thereby adding turbulence to further mix the material.
