Description

The two-way docking facilities of axle sleeve type based on metal filter bag
Technical field
It the utility model is related to a kind of two-way docking facilities of the axle sleeve type based on metal filter bag.
Background technology
Metal filter bag because its high temperature resistant, it is corrosion-resistant, can recycle many advantages, such as, be widely used in coal chemical industry, The industries such as metallurgy.But metal filtrate is not foldable, therefore the filtrate respectively saved must be transported again in integral solder shaping with bag cage in factory Installed toward field joint.
For screw thread or flange arrangement, both modes there are problems that the mounting means used at present:First, screw thread knot The problem of structure axiality of two sections filter bag in docking is relatively difficult to ensure card, and its pretightning force deficiency easily causes poor sealing;Its Secondary, flange arrangement needs to screw greater number of bolt in docking, and installment work is less efficient.
Utility model content
The purpose of this utility model is to overcome above-mentioned the shortcomings of the prior art part, there is provided a kind of to be based on metal The two-way docking facilities of axle sleeve type of filter bag, it can not only realize the convenient docking of two section filter bags, ensure axiality and its sealing Property, and it is easy for installation, improve installment work efficiency.
To achieve the above object, the technical solution of the utility model is:A kind of axle sleeve type based on metal filter bag is two-way right Connection device, including two weld ports being oppositely arranged, be respectively provided at two weld ports periphery cap bag and be located at two welding ends The connecting pipe box of connection function are impaled outside mouthful;The epimere of the weld port is pipe, and stage casing outer wall is provided with external screw thread, hypomere For trapezoidal transition section, three sections hollow and coaxial, and pipe external diameter is less than the externally threaded diameter in stage casing;The cap bag upper end is provided with first Internal thread, lower end are provided with the second internal thread, and the aperture of first internal thread is more than the aperture of the second internal thread, and cap bag passes through institute Pipe, the external screw thread mating connection of the second internal thread and weld port are stated, and installation connecting pipe box are left between cap bag and pipe The space of port;It is in hollow cylindrical inside the connecting pipe box, the outer wall at both ends is provided with and first screw-internal thread fit External screw thread, the pipe external diameter can be inserted it into inside connection sleeve pipe just.
Further, in addition to sealing ring, the sealing ring are located between the pipe of two weld ports, outside sealing ring Wall and the inwall of connecting pipe box are interference fitted.
Further, the opposite, diameter of external screw thread screw thread at the connecting pipe box both ends etc. is big.
Further, the trapezoidal transition section of the weld port uses with the welding of metal filter bag.
Compared with existing mounting means, the beneficial effects of the utility model are:It is waney by being set in cap bag The external screw thread of segmented thread, its first internal thread and connecting pipe box coordinates, and the external screw thread of the second internal thread and weld port coordinates, Make the pipe of two weld ports can be brought into close contact in connecting pipe box, ensure the axiality and sealing of two section filter bags, and even The outer wall at adapter set both ends is threaded the big external screw threads such as opposite, diameter, and in docking, rotatable connection pipe sleeve can revolve simultaneously Tight two weld ports, it is easy for installation, operating efficiency can be effectively improved.
Brief description of the drawings
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the semi-cutaway of the utility model weld port;
Fig. 3 is the sectional view of the utility model cap bag;
In figure:1 weld port, 1-1 pipes, 1-2 external screw threads, 1-3 trapezoidal transition sections, 2 cap bags, the internal threads of 2-1 first, 2- 2 second internal threads, 3 connecting pipe box, 4 sealing rings.
Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of two-way docking facilities of axle sleeve type based on metal filter bag, including two welding being oppositely arranged Port 1, it is respectively provided at the peripheral cap bag 2 of two weld ports and is located at the connecting pipe box 3 that connection function is impaled outside two weld ports; The epimere of the weld port 1 is pipe 1-1, and stage casing outer wall is provided with external screw thread 1-2, and hypomere is trapezoidal transition section 1-3, three sections Hollow and coaxial, pipe 1-1 external diameters are less than stage casing external screw thread 1-2 diameter;The upper end of cap bag 2 is provided with the first internal thread 2-1, Aperture of the lower end provided with the second internal thread 2-2, the first internal thread 2-1 is more than the second internal thread 2-2 aperture, and cap bag 2 is worn Cross the pipe 1-1, the second internal thread 2-1 and the external screw thread 1-2 of weld port 1 are connected, and cap bag 2 and pipe 1-1 it Between leave the space of installation connecting pipe box 3 port;The inside of connecting pipe box 3 is in hollow cylindrical, and the outer wall at both ends is provided with The external screw thread coordinated with the first internal thread 2-1, the pipe 1-1 external diameters can be inserted it into inside connection sleeve pipe 3 just.
