Abstract
The utility model relates to a bubble cap which is the component of a bubble cap column of a chemical engineering device. The utility model is characterized in that the connection of a cap body and an air raising tube is designed into the sheathed connection through a supporting foot on the air raising tube and a supporting hole on the cap body, and the cap body and the air raising tube are fastened by a bumper pin which has a positioning structure. The bubble cap which is especially suitable for being made from polytetrafluoroethylene material has the advantage of assembly without welding. The appearance of the polytetrafluoroethylene bubble cap can overcome the defects of no corrosion resistance, short service life, etc. of a metal bubble cap and provides the condition for making the bubble cap column made of polytetrafluoroethylene. Therefore, the utility model has obvious economic benefit and social benefit.
Description
The present invention relates to the member of chemical industry equipment bubble column, a kind of bubble-cap.
Known bubble-cap is all made with metal material, and general metal material is not corrosion-resistant, causes bubble-cap short service life, adopt the manufacturing of noble dilute metal material, though decay resistance can improve, but still can not satisfy the technological requirement that deep-etching and high-purity medium are produced, and involve great expense.Adopt the polytetrafluoroethylene (PTFE) of any chemical mediator corrosion of ability to make bubble-cap, optimal selection that yes, but, the metal bubble-cap is that the method by support iron and welding links together cover body and riser and forms, because polytetrafluoroethylene (PTFE) can not weldering property, obviously it is impossible making the polytetrafluoroethylene (PTFE) bubble-cap with the metal blister configuration, at present, does not also occur the bubble-cap made from polytetrafluoroethylene (PTFE) both at home and abroad.
The purpose of this invention is to provide the bubble-cap that a kind of suitable especially polytetrafluoroethylene (PTFE) is made.
The riser of this bubble-cap and cover body are respectively equipped with support foot and support holes, and support foot and support holes match, and also are provided with supporting shoulder and shelves pin-and-hole on the support foot, and the shelves pin-and-hole matches with the shelves pin, and the shelves pin also has location structure.
The accompanying drawing of this specification has:
Fig. 1: riser structure chart;
Fig. 2: cover body vertical view;
Fig. 3: blister configuration figure;
Fig. 4: one of shelves keying composition;
Fig. 5: two of shelves keying composition;
Fig. 6: three of shelves keying composition;
Fig. 7: with the supporting open annular keying composition of Fig. 6 shelves pin.
Below in conjunction with accompanying drawing content of the present invention is described in further detail.
The main member that consists of bubble-cap is cover body (1) and riser (2), one of riser (2) is provided with connecting thread, the other end is provided with three support foots along the riser circumference uniform distribution (3), and supporting shoulder (4) and shelves pin-and-hole (5) are set on the support foot (3). The skirt section of cover body (1) is provided with uniform through hole (6), and the top is provided with the support holes (7) that same support foot (3) matches, after cover body (1) packs into the support foot (3) of riser (2), by supporting shoulder (4) supporting. And sells the position that (8) define cover body (1) together jointly with the shelves that are inserted in grade pin-and-hole (5), because polytetrafluoroethylene can be good from slip, for anti-banking pin (8) skids off, shelves pins (8) should have location structure, introduce below the location structure of three kinds of shelves pins:
Scheme one: shelves pin (8) same ring washers (9) are made of one, as shown in Figure 4.The internal diameter of ring washer (9) equals the external diameter of support foot (3).
Scheme two: shelves pin (8) same washers (10) are made of one, as shown in Figure 5.The external diameter of washer (10) equals the internal diameter of support foot (3).
Scheme three: shelves pins (8) are done wedgewise, as shown in Figure 6.Shelves pins (8) are provided with cotter way (11), and open annular pin (12) is inserted in the cotter way (11), and the external diameter of open annular pin (12) equals the internal diameter of support foot (3).
Above-mentioned blister configuration is that the material behavior according to polytetrafluoroethylene (PTFE) designs, and design feature has three: one, and cover body connects with the riser suit; The 2nd, it is solid to adopt shelves to lock; The 3rd, have the location structure that anti-banking pin skids off.Therefore, this bubble-cap does not need welding just can assemble, and suits especially to make with polytetrafluoroethylmaterial material.The appearance of polytetrafluoroethylene (PTFE) bubble-cap will overcome the existing drawback ， And of metal bubble-cap for the bubble column of making polytetrafluoroethylene (PTFE) provides condition, therefore, have tangible economic benefit and social benefit.
Claims (4)
1, a kind of bubble-cap of forming by cover body and riser, it is characterized in that: riser (2) and cover body (1) are respectively equipped with support foot (3) and support holes (7), the same support holes of support foot (3) (7) matches, also be provided with supporting shoulder (4) and shelves pin-and-hole (5) on the support foot (3), shelves pin-and-holes (5) match with shelves pins (8), and shelves pins (8) also have location structure.
2, bubble-cap according to claim 1 is characterized in that: described location structure is ring washer (9), and shelves pin (8) same ring washers (9) are made of one.
3, bubble-cap according to claim 1 is characterized in that: described location structure is washer (10), and shelves pin (8) same washers (10) are made of one.
4, bubble-cap according to claim 1 is characterized in that: shelves pins (8) are provided with cotter way (11), and described location structure is open annular pin (12), and open annular pin (12) is inserted in the cotter way (11).
