Description
Technical field
The utility model relates to chemical filler field, is specifically related to plastics cascade ring.
Background technology
Chemical filler has excellent acidproof heat-proof performance, the various inorganic acids of ability except hydrofluoric acid, the corrosion of organic acid and organic solvent, can be used in various occasions, and range of application is very extensive, can be used for chemical industry, metallurgical, the drying tower of the industries such as coal gas oxygen, absorption tower, scrubbing tower, regenerator, can be divided three classes according to material: ceramic packing, plastic filler, metal packing, wherein, plastic filler has lightweight, heat-resisting, the features such as resistance to chemical attack, comprise PP, PE, RPP, PVC, CPVC, the tower packing that the materials such as PVDF are made, it is large that plastic filler has voidage, pressure drop and height of transfer unit are low, spotting out is high, vapour-liquid contact fully, mass-transfer efficiency high, plastic filler comprises cascade ring, its side has increased flange, not only can increase the mechanical strength of packing ring, and owing to having destroyed the symmetry of filling-material structure, thereby the directed probability when having increased filler and throwing in, again due to the impact of flange, make filler when piling up the contact between filler annular space by take linearity contact as main transformer is as take a contact as main, like this, not only increased the space between filler particles, reduced the resistance of gas through packing layer, and these contact points can also converge spaced point for what liquid flowed along filling surface, thereby promoted the Surface Renewal of liquid film, be conducive to the raising of filler mass-transfer efficiency.But owing to having increased flange on plastics cascade ring, the phenomenon that flange when filler is piled up on the frequent long-living plastics cascade ring side by side of meeting overlaps each other, cause the end face of adjacent plastics cascade ring not in same plane, on the contrary a contact has been become to the face contact of flange, greatly affected the mass-transfer efficiency of filler.
Summary of the invention
Technical problem to be solved in the utility model is to provide plastics cascade ring, reasonable in design, simple in structure, can avoid overlapping each other of adjacent plastics cascade ring upper overturning, make the end face of adjacent plastics cascade ring in same plane, guarantee the some contact between adjacent plastics cascade ring.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: plastics cascade ring, comprise ring wall, be connected to the flange of ring wall upper end, be located at the fenestra on ring wall, evenly be located in ring wall in the sheet that lolls, be embedded the reinforcing ring lolling on sheet interior, on described ring wall, between adjacent windows hole, be provided with limited block or stopper slot, described limited block and stopper slot are disposed on ring wall, described limited block and stopper slot match, the cross section of described limited block adopts triangular structure, described stopper slot is provided with two and caves inward and crossing slope, two described slopes coordinate spacing with the triangle tip of limited block.
As preferably, on described flange, be connected with stopping means, described stopping means comprises two banking stops that are parallel to each other, the brace that is connected to two banking stop central authorities, and described brace is vertical with banking stop, forms the draw-in groove of clamping flange between described two banking stops and brace.By stopping means, the flange of adjacent plastics cascade ring can be carried out to spacing connection, effectively guarantee that the end face of adjacent plastics cascade ring, in same plane, further avoided overlapping each other of adjacent plastics cascade ring upper overturning.
As preferably, the side of described banking stop adopts the arc structure caving inward, identical with the radian of described flange.Easily manufactured, reduced the raw materials for production of the arc structure part caving inward, saved manufacturing cost.
As preferably, described banking stop adopts quality of rubber materials, and described brace adopts rigid plastics.The banking stop of quality of rubber materials has been avoided the scuffing to flange, and the brace of rigid plastics has guaranteed the stability connecting.
Beneficial effect:
The plastics cascade ring that the utility model adopts technique scheme to provide, reasonable in design, simple in structure, can avoid overlapping each other of adjacent plastics cascade ring upper overturning, make the end face of adjacent plastics cascade ring in same plane, guarantee the some contact between adjacent plastics cascade ring, reduce gas-liquid through the resistance of packing layer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of stopping means in the utility model.
In figure, ring wall 1, fenestra 11, flange 2, in loll sheet 3, reinforcing ring 4, limited block 5, stopper slot 6, slope 61, stopping means 7, banking stop 71, brace 72.
The specific embodiment
As depicted in figs. 1 and 2, plastics cascade ring, comprise ring wall 1, be connected to the flange 2 of ring wall 1 upper end, be located at the fenestra 11 on ring wall 1, evenly be located in ring wall 1 in the sheet 3 that lolls, be embedded the reinforcing ring 4 lolling on sheet 3 interior, on described ring wall 1, between adjacent windows hole 11, be provided with limited block 5 or stopper slot 6, described limited block 5 is disposed on ring wall 1 with stopper slot 6, described limited block 5 matches with stopper slot 6, the cross section of described limited block 5 adopts triangular structure, described stopper slot 6 is provided with two and caves inward and crossing slope 61, two described slopes 61 coordinate spacing with the triangle tip of limited block 5.On described flange 2, be connected with stopping means 7, described stopping means 7 comprises two banking stops 71 that are parallel to each other, the brace 72 that is connected to two banking stop 71 central authorities, described brace 72 is vertical with banking stop 71, forms the draw-in groove of clamping flange 2 between described two banking stops 71 and brace 72.The side of described banking stop 71 adopts the arc structure caving inward, identical with the radian of described flange 2.Described banking stop 71 adopts quality of rubber materials, and described brace 72 adopts rigid plastics.
