Abstract
The utility model belongs to the technical field of pipeline connecting and particularly relates to a connection flange device for pneumatic conveying pipelines. The connection flange device for the pneumatic conveying pipelines consists of a tapered flange I, a tapered flange II and a seal ring, wherein the tapered flange I consists of a tapered pipe and a disc flange I fixedly connected with the major-diameter end of the tapered pipe; the tapered flange II consists of a tapered gyrorotor of which the outer surface is tapered and the inner surface is cylindrical, and a disc flange II fixedly connected with the major-diameter end of the tapered gyrorotor; the seal ring is respectively and mutually abutted with the minor-diameter end face of the tapered gyrorotor and the inner surface of the tapered pipe; the inner surface of the tapered pipe and the outer surface of the tapered gyrorotor are consistent in taper; an inner bore at the major-diameter end of the tapered gyrorotor is mutually connected with one pneumatic conveying pipelines; and the minor-diameter end of the tapered pipe is mutually connected with the other pneumatic conveying pipeline. According to the connection flange device for two pneumatic conveying pipelines, when two of the pneumatic conveying pipelines are connected, the inner diameters of the flanges are kept consistent with those of the pipelines, therefore, the eddy disturbance is eliminated, the abrasion is reduced, and the service lives of the pipelines are prolonged. The production working environment is protected and improved.
Description
Technical field
The utility model belongs to the pipeline connection technology field, relates in particular to a kind of air delivery pipe flange device.
Background technique
It is the mass transport technology of rising in recent years that the electro-precipitating dust wind that contains irony, high gravity, coarse size send.In wind send the design of pipeline, prolong the design standard with wind, water class, that is: flange is the plug-in type welding always, and two flanges have certain clearance after connecing between the tube head of two side pipes.Between two pipe joints, produce vortex disturbance when wind send material, produce wearing and tearing between the flange of dust granules and delivery air direction and tube head, the weld mill leakage at flange and pipeline needs maintenance soldering repeatedly, influences ordinary production.
Summary of the invention
The purpose of the utility model is to provide a kind of simple in structure, working life of prolonging pipeline, reduces dust and leaks, and the protection environment reduces the air delivery pipe flange device of materials consumption.
The purpose of the utility model realizes through following technical proposals:
The air delivery pipe flange device of the utility model; It is characterized in that by the cone-shaped flange I; The cone-shaped flange II and the seal ring that are abutted against mutually of cone-shaped flange I formed therewith; Described cone-shaped flange I is made up of the disc flange I that Taper Pipe is fixedly connected with the bigger diameter end of Taper Pipe therewith; Said cone-shaped flange II is made up of the disc flange II that outer surface taper, the columniform taper solid of rotation of internal surface are fixedly connected with the bigger diameter end of taper solid of rotation therewith, and described seal ring is abutted against with the path end face and the described Taper Pipe internal surface of described taper solid of rotation respectively mutually, and described Taper Pipe internal surface is consistent with the tapering of the outer surface of described taper solid of rotation; The endoporus of described taper solid of rotation bigger diameter end is connected with an air delivery pipe, and described Taper Pipe miner diameter end is connected with another air delivery pipe.
The advantage of the utility model:
The utility model connect two air delivery pipes the time keep the flange internal diameter consistent with internal diameter of the pipeline, eliminate vortex disturbance, reduce wear prolongation pipeline working life.Protect, improve the manufacturing operation environment.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Embodiment below in conjunction with description of drawings the utility model.
As shown in Figure 1: the air delivery pipe flange device of the utility model; It is characterized in that by cone-shaped flange I 2; The cone-shaped flange I 2 cone-shaped flange II of being abutted against mutually 3 and 4 compositions of seal ring therewith; Described cone-shaped flange I 2 is made up of the disc flange I that Taper Pipe is fixedly connected with the bigger diameter end of Taper Pipe therewith; Said cone-shaped flange II is made up of the disc flange II that outer surface taper, the columniform taper solid of rotation of internal surface are fixedly connected with the bigger diameter end of taper solid of rotation therewith; Described seal ring 4 is abutted against with the path end face and the described Taper Pipe internal surface of described taper solid of rotation respectively mutually; Described Taper Pipe internal surface is consistent with the tapering of the outer surface of described taper solid of rotation, and the endoporus of described taper solid of rotation bigger diameter end is connected with an air delivery pipe 1, and described Taper Pipe miner diameter end is connected with another air delivery pipe 5.The annexation of above-mentioned two kinds of cone-shaped flanges and air delivery pipe has been avoided the tube end phenomenon of wearing and tearing too early, the working life of improving pipeline.
