Description
Technical Field
The utility model relates to a part of rubber refining equipment, concretely relates to a rubber smelts roller that is used for extruding rubber in the banbury mixer.
Background
In the rubber product production process, need refine the crude rubber, be called and smelt gluey, at the gluey in-process, the heat that refining roller department produced is the most, be difficult to distribute away relatively fast, for distributing away the produced heat of refining in-process, set up the shower in the inner chamber of refining roller, cool off the inner wall of refining roller, take away the heat through the cooling water, but because refining roller is in the rotation, the shower is relatively poor to the cooling effect of the roll body when being in upper portion, cause holistic cooling effect relatively poor, restricted the refining in-process, the rotational speed and the pressure of refining roller, influence the efficiency of smelting gluey.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned defect, provide a can improve the roller of smelting of cooling effect to improve and smelt gluey efficiency, specific technical scheme is:
a rubber refining roller comprises a rotor, wherein the rotor comprises a body with a cylindrical part and ribs spirally arranged on the outer circumferential surface of the cylindrical part, a cooling cavity is formed between each rib and the cylindrical part, cooling pipes are welded on the inner walls of the ribs and spirally surround along the outer side of the cylindrical part; an inner cavity is arranged in the body, extends along the axial direction of the rotor and is provided with a cavity opening on the end surface of one end of the rotor; the cooling pipe is a half pipe, and a channel for cooling water to flow is formed between the half pipe and the inner wall of the convex rib;
a water inlet pipe and a water outlet pipe are arranged in the inner cavity, a first inlet end and a first outlet end are respectively formed at two ends of the water inlet pipe, and a second inlet end and a second outlet end are respectively formed at two ends of the water outlet pipe; the first outlet end is communicated with a water inlet of the cooling pipe, and the second inlet end is communicated with a water outlet of the cooling pipe; and a rotary joint with two channels is arranged outside the cavity opening, a first inlet end is communicated with one channel of the two channels, and a second outlet end is communicated with the other channel of the two channels. Preferably, the rib is welded to the outer circumferential surface of the cylindrical portion.
In this application, the mode that adopts the independent setting forms the bead at the surface of body, this bead is used for extrudeing the refining to the crude rubber, weld the cooling tube on the inner wall of bead, the cooling tube is half a pipe, be about to the pipeline divide into two halves back along the axis direction, weld two sides of half a pipe on the inner wall of bead, make the flow channel who forms the cooling water between the inner wall of half a pipe and bead, because the cooling water is restricted in a narrow and small cavity, can directly cool off the bead, can take away the produced heat of elastomeric in-process fast, in order to reduce the temperature of bead, because can directly take away the produced heat when extruding the crude rubber fast, can suitably improve the speed and the pressure of refining the roller, in order to improve production efficiency.
Furthermore, in order to facilitate installation and adjustment of connection of the water inlet pipe, the water outlet pipe and the cooling pipe, the first outlet end is communicated with the water inlet of the cooling pipe through the first metal soft joint, and the second inlet end is communicated with the water outlet of the cooling pipe through the second metal soft joint. After the metal soft joint is adopted, the expansion amount of the pipeline caused by expansion with heat and contraction with cold can be buffered, and the connection effectiveness of the water inlet pipe, the water outlet pipe and the cooling pipe is ensured.
Furthermore, in order to conveniently position the water inlet pipe and the water outlet pipe during installation, a supporting piece for fixing the water inlet pipe and the water outlet pipe is arranged in the inner cavity of the body.
