Abstract
The utility model discloses a polytetrafluoroethylene grid plate with a die-pressed steel liner. The polytetrafluoroethylene grid plate with the die-pressed steel liner comprises a polytetrafluoroethylene ring frame and polytetrafluoroethylene grids arranged in the ring frame, wherein each grid comprises ribs and a strip-shaped space among the ribs; and the ring frame and the ribs are internally provided with steel inner liners. As the polytetrafluoroethylene grid plate is internally provided with the steel inner liners, a distributor adopting the grid plate when being used at a high temperature of 200 DEG C has the advantages of no deformation for a long term use, uniform liquid distribution, great support intensity, long use time and high production effectiveness.
Description
Technical field
The utility model relates to sparger.
Background technique
Tetrafluoro screen working process does in the existing technology, on the mould of required specification, adds polytetrafluoroethylene powder, on oil hydraulic press, pressurizes, and demoulding sintering is then come out of the stove, and gained after processing that is to say that screen is whole tetrafluoro structure.
But because the tetrafluoro screen uses down at 200 degrees centigrade high temperature, the easy modification of product, liquid distribution is inhomogeneous, support strength is poor, service time is short, influence production, the reduction benefit.
The model utility content
The utility model technical problem to be solved just provides a kind of mold pressing steel lining tetrafluoro screen and adopts the sparger of this screen, and high temperature resistant and not yielding, service time is long, and economic benefit is high.
For solving the problems of the technologies described above; The utility model adopts following technological scheme: mold pressing steel lining tetrafluoro screen; Comprise tetrafluoro annulus frame and be located at the tetrafluoro grid in the annulus frame; Said grid comprises the bar shaped space between rib and rib, it is characterized in that: be provided with the steel liner in said annulus frame and the rib.
Preferably, the steel liner in the said annulus frame is the ring steel plate.
Preferably, the steel liner in the said rib is cylindrical reinforcing bar.
The utility model also provides the sparger that adopts above-mentioned mold pressing steel lining tetrafluoro screen, and at first welded reinforcement ring in the bar shaped space of grid at the good tetrafluoro of reinforced steel bar ring liner, tightly puts the tetrafluoro distributing tube then after the fine finishing, reinforces with the PFA welding rod at last.
Further, vertical smooth being enclosed within the reinforced steel bar ring that has served as a contrast tetrafluoro of said tetrafluoro distributing tube.
Further, said distributing tube external diameter has a step, guarantees that distributing tube is on same horizontal plane.
The utility model is owing to be provided with the steel liner in the tetrafluoro screen, thereby the sparger that adopts this screen is under 200 degrees centigrade high temperature, use for a long time indeformable, liquid distribution is even, support strength is big, service time is long, the productivity effect height.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the utility model plan view;
Fig. 2 is an A-A sectional view among Fig. 1;
Fig. 3 is the sparger sectional view;
Fig. 4 is the sparger plan view.
Embodiment
The embodiment of the utility model mold pressing steel lining tetrafluoro screen as depicted in figs. 1 and 2; Comprise tetrafluoro annulus frame 1 and be located at the tetrafluoro grid in the annulus frame; Said grid comprises the bar shaped space 2 between rib 3 and rib, is provided with the steel liner in said annulus frame and the rib.Steel liner in the said annulus frame is a ring steel plate 4.Steel liner in the said rib is cylindrical reinforcing bar 5.Rib 3 wherein and the bar shaped space 2 between rib are arranged in parallel, and two semicircle sides are respectively established row's grid, grid symmetric arrays in the two semicircle sides in the annulus frame.
Like Fig. 3 and shown in Figure 4; Adopt the sparger of above-mentioned mold pressing steel lining tetrafluoro screen; Welded reinforcement ring in the bar shaped space of grid at first; At the good tetrafluoro of reinforced steel bar ring liner (being equivalent to cover in the tetrafluoro), (be about to the interior cover of tetrafluoro endoporus and be machined to required size) after the fine finishing tightly put tetrafluoro distributing tube 6 then, reinforce with the PFA welding rod at last.Vertical smooth being enclosed within the reinforced steel bar ring that has served as a contrast tetrafluoro of said tetrafluoro distributing tube.Said distributing tube external diameter has a step, guarantees that distributing tube is on same horizontal plane.
The working process of the utility model tetrafluoro screen is: add the tetrafluoro powder successively uniformly after fixing mould; Embed the steelframe (steel liner, the overall structure of forming by ring steel plate and cylindrical reinforcing bar) of required specification when reaching certain thickness again, continue to add the tetrafluoro powder; Make it reach the requirement specification; The demoulding of pressurizeing again, sintering is come out of the stove then, gained after the surface finishing.
Claims (3)
1. mold pressing steel lining tetrafluoro screen comprises tetrafluoro annulus frame (1) and is located at the tetrafluoro grid in the annulus frame, and said grid comprises the bar shaped space (2) between rib (3) and rib, it is characterized in that: be provided with the steel liner in said annulus frame and the rib.
2. mold pressing steel lining tetrafluoro screen according to claim 1 is characterized in that: the steel liner in the said annulus frame is ring steel plate (4).
3. mold pressing steel lining tetrafluoro screen according to claim 1 is characterized in that: the steel liner in the said rib is cylindrical reinforcing bar (5).
