Abstract
The utility model discloses an indirect air-cooled pipe bundle bottom header, which includes a header body (1), a header bottom (2), a header cover (3) and a baffle plate (4) that are formed into an integral structure, wherein a support plate (5) is arranged at the bottom of the header bottom (2). The header body, a header bottom, the header cover and the baffle plate are formed once for all through heat extrusion into a whole, thereby not only reducing the processing procedure, but also solving the welding quality problem frequent for the traditional bottom header; as the arc-shaped liner plate is additionally arranged between the header bottom and the support plate to enlarge the contact area of the header bottom and the support plate, the stress is uniformly distributed and the service life of the bottom header is prolonged; and the shape of the cross section of the header bottom is designed into an arc shape with a flat bottom part, so that the header bottom is effectively prevented from being deformed and the service life of the header bottom is prolonged.
Description
Technical field
The utility model relates to a kind of indirect air cooling tube bank bottom header, belongs to the electric power factory equipment field.
Background technology
In the indirect air cooling system of power plant, the indirect air cooling tube bank is a core component, and the bottom of indirect air cooling tube bank is installed on the header of bottom.In the prior art, there is following shortcoming in indirect air cooling tube bank bottom header:
Processing technology is complicated; The indirect air cooling tube bank bottom header that present most of power plant uses all adopts structure as shown in Figure 4, at first with at the bottom of casing, the case, case lid and dividing plate produce respectively, and then with at the bottom of casing, the case, case lid and dividing plate assembling and weld together; Because power plant is very high to the requirement of equipment; Therefore when welding, require welding quality very high, this traditional processing method production efficiency is very low, and is easy to occur problems of welded quality.
Local stress is big; Be circular arc at the bottom of the case of the indirect air cooling tube bank bottom header that uses at present; And the top of supporting the gripper shoe at the bottom of the case is the plane, at the bottom of the case of the top of this gripper shoe header bottom the indirect air cooling tube bank between for line contacts, the stress of contact position is bigger; Big inharmonious distortion takes place at the bottom of the case easily, influences the safe handling of equipment.
The utility model content
The purpose of the utility model is, a kind of indirect air cooling tube bank bottom header is provided, and it is simple that it has processing technology, and the stress distribution situation is good, the advantage of long service life.
The technical scheme of the utility model: a kind of indirect air cooling tube bank bottom header, comprise casing, case at the bottom of, case lid and dividing plate, at the bottom of casing, the case, case lid and dividing plate be an overall structure, the bottom at the bottom of the case is provided with gripper shoe.Adopt this integral type design to make and both reduced manufacturing procedure, problems of welded quality can not occur again.
In the header of aforesaid this indirect air cooling tube bank bottom, the cross sectional shape at the bottom of the case is a circular arc.
In the header of aforesaid this indirect air cooling tube bank bottom, be provided with the arc backing plate at the bottom of the case and between the gripper shoe; Matching with at the bottom of the case in the top of arc backing plate, matches with the top of gripper shoe in the bottom of arc backing plate.At the bottom of the arc backing plate being set at the bottom of the case and between the gripper shoe can also solve case, directly contact the excessive problem of local stress, prolong the service life of bottom header with gripper shoe.
In the header of aforesaid this indirect air cooling tube bank bottom, the cross sectional shape at the bottom of the case is that the bottom is the circular arc on plane.It is the circular arc on plane that shaped design at the bottom of the case is become the bottom surface, can strengthen the contact area at the bottom of the case and between the support bar, and stress is evenly distributed, and prevents at the bottom of the case big inharmonious distortion to take place, and prolongs its service life.
Compared with prior art; The utility model since the mode through hot extrusion with casing, case at the bottom of, case lid and the disposable extrusion molding of dividing plate; Make them as a whole, so both reduced manufacturing procedure, can solve the problem that welding quality appears in tradition bottom header easily again.
Owing to setting up the arc backing plate at the bottom of the case and between the gripper shoe, make at the bottom of the case contact area with gripper shoe become big, stress is evenly distributed, prolong the service life of bottom header.
Because it is the circular arc on plane that the cross sectional shape at the bottom of the case is designed to the bottom, effectively prevents to deform at the bottom of the case, prolongs its service life.
