Abstract
The utility model discloses an enhanced liquid nitrogen joint of a pulverizer. The enhanced liquid nitrogen joint of the pulverizer comprises a connecting protruding block and a heat dissipation base; the center of the connecting protruding block is provided with a pair of connecting through holes; four corners of the connecting protruding block are respectively provided with a connecting screw; and a connecting pipe-entering joint and a connecting pipe-exiting joint are respectively arranged in the connecting through holes. According to the enhanced liquid nitrogen joint of the pulverizer of the utility model, heat dissipation fins on the connecting protruding block and the heat dissipation base are utilized, and therefore, flow disturbing performance of liquid nitrogen can be to greatly enhanced, heat dissipation performance of the liquid nitrogen joint is enhanced, and the stability of a control portion of a variable frequency motor of the pulverizer can be improved.
Description
Technical field
The utility model relates to a kind of disintegrating apparatus, or rather, is a kind of enhanced type liquid nitrogen joint of pulverizer.
Background technology
Pulverizer is a kind of common materiel machining device, usually is used for pulverizing and the processing of material.Because the caloric value of the control part of the variable-frequency motor of pulverizer is large, usually need special radiator.Because the liquid nitrogen conduit of the inside of pulverizer need to bend cabling, existing liquid nitrogen conduit adopts the double back pipe of 180 °, and the joint of this double back pipe is adopted and is welded to connect, because the internal vibration of pulverizer is larger, the as easy as rolling off a log fracture of weld causes liquid nitrogen system to lose efficacy.
Summary of the invention
The utility model is mainly to solve the existing technical problem of prior art, thereby a kind of enhanced type liquid nitrogen joint of pulverizer is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of enhanced type liquid nitrogen joint of pulverizer, the enhanced type liquid nitrogen joint of described pulverizer comprises one and connects projection and a heat dissipation base, the middle part of described connection projection is provided with a pair of connecting through hole, be respectively equipped with an attachment screw on four jiaos of the connection projection, be respectively equipped with a connection inlet pipe joint in described connecting through hole and connect pipe joint with being connected.
As preferred embodiment of the present utility model, the middle part of described heat dissipation base is provided with radiating fin, and four jiaos of heat dissipation base are respectively equipped with a fixed via, and described attachment screw runs through respectively described fixed via.
As preferred embodiment of the present utility model, the upper surface of described connection projection is provided with radiating fin.
As preferred embodiment of the present utility model, described connection projection and heat dissipation base are aluminium alloy and make.
Radiating fin on the enhanced type liquid nitrogen connector by using connection projection of pulverizer of the present utility model and the radiating fin on heat dissipation base, greatly strengthened the flow-disturbing performance of liquid nitrogen, improve the heat dispersion of liquid nitrogen joint, improved the stability of control part of the variable-frequency motor of pulverizer.
