Abstract

The utility model relates to a single core type resin trapping device, which is composed of an upper head, a trapping tube, a stainless steel net, a terylene net, a casing body, a window, etc. Nets with different fineness can be selected according to the different graininess of the ion exchange resin; the trapping tube is of a porous single core type, the surface of the trapping tube is sheathed with two nets with different mesh numbers and materials, the inner layer is the terylene net with 20-40 meshes, and the outer layer is the stainless steel net with 40-60 meshes. The single core type resin trapping device has the advantages of simple structure, simple machining, little resistance, no static electricity during the motion of the terylene net and the stainless steel net, no clogging, strong trapping reliability, long busy period, and convenient cleaning and maintenance.

Description

The single core type resin catcher

The utility model is to belong to a kind of mechanical filter.

At present, the resin catcher of use has and twines bundled tube, this trap complex structure, and difficulty of processing is big, the cost height, and also it is easily dirty stifled to twine the slit, causes resistance big, exerting oneself of ion-exchanger descended reaches more than 50%.Rock wool bundled tube resin catcher, life cycle is short, and maintenance capacity is big, the also corresponding raising of production cost.

The purpose of this utility model is to make a kind of single core type resin catcher, adopts the single core type trap tube, and pipe is outer the different fineness web material, and it is easily dirty stifled to solve above-mentioned trap, and resistance is big, and the deficiency that life cycle is short is convenient to make and maintenance.

The utility model mainly contains upper cover 1, trap tube 2, stainless (steel) wire 3, terylene net 4, housing 5, form 6 compositions, as shown in Figure 1.Its operation principle is the granularity difference according to ion exchange resin, selects the net of different fineness for use, thereby allows water pass through the trap screen pipe, the ion exchange resin filtering that ion-exchanger is leached.The cross section in each hole, surface of trap tube should equal trap outlet or inlet tube sectional area 2-3 times in the trap, can guarantee that so made trap resistance is little.On the upper cover 1 outlet is arranged, on the housing 5 inlet is arranged, there is row's resin mouth the lower end, form 6 connects with housing 5 surfaces, can observe the situation of collecting resin, and Circular Plate is arranged at trap tube 2 tops, place in the middle of the ring flange of upper cover 1 and housing 5, be connected and fixed together with bolt, nut.It is characterized in that: trap tube 2 is porous single core types, the surface cover two-layer different meshes of connection of pipe and the net of material, and internal layer is 20-40 purpose terylene nets 4, skin is 40-60 purpose stainless (steel) wires 5.

During use, the filtrate that will have a resin is entered in the housing by the inlet of trap housing, enter in the trap tube through the two-layer different meshes on trap tube surface and the net of material, outlet by upper cover is discharged, resin is filtered in trap tube surface on the net, the outlet backwash water is washed out the resin of screen surface to the certain hour water from upper cover, gets rid of resin by the housing lower port.When refiltering, repeat said process, removing resin that can be again and again.

The utility model compared with prior art owing to adopt porous single core type chimney filter, is extracted the net of two-layer different meshes and material outward, its designs simplification, easy to process, cost is low, resistance seldom, terylene net and stainless steel cloth, the no static that is in operation does not have dirty stifled, the internal layer coarse net mainly acts on the wearing and tearing that reduce outer net and is provided with, the good reliability that captures, life cycle is long, clears up easy to maintenance.

Figure is a general structure cutaway view of the present utility model.

Embodiment of the present utility model:

The single core type resin catcher mainly is made up of upper cover 1, trap tube 2, stainless (steel) wire 3, terylene net 4, housing 5 and form 6, as shown in Figure 1.Wherein loam cake 1 usefulness steel plate is made, and the upper and lower is welded with ring flange, and outlet is arranged at top.Housing 5 usefulness steel plates are made, one side has inlet, there is sewage draining exit the lower end, form connects with surface of shell with screw, trap tube can be injection molded into polyvinyl chloride, also available stainless steel, and there are a plurality of holes on the surface, outlet that its area sum is upper cover, housing or 2-3 times of inlet area guarantee that the trap resistance is little.Stainless (steel) wire is 40-60 orders, and the terylene mesh is 20-40 orders.

Terylene net 4 cover is associated on the surface of trap tube 2, and stainless (steel) wire 3 covers are associated on terylene net 4 surfaces, and trap tube 2 cards that combine are placed in the middle of housing 5 and upper cover 1 ring flange, are fixedly connected composition single core type resin catcher with bolt, nut.

During use, the lower end sewage draining exit of housing 5 is sealed, filtered fluid is entered in the housing 5 by the housing inlet, screen pack on trap tube 2 enters in the trap tube 2, is discharged by upper cover 1 outlet, can see that the screen pack surface resin accumulates situation by form, when acquiring a certain degree, open upper cover 1 outlet and add into water, clean the resin on the trap surface mesh, discharge by housing 5 lower end sewage draining exits.After sealing, can proceed the trap filter resin again.

Claims

1, a kind of single core type resin catcher, form by upper cover, screen pipe, housing, form, upper cover has outlet, inlet is arranged on the housing, and form connects with surface of shell, and the ring flange of screen pipe top and upper cover, housing is linked together with bolt, nut, it is characterized in that: trap tube (2) is the porous single core type, the net of the two-layer different meshes of trap tube (2) surface cover connection, material, internal layer is 20-40 purpose terylene nets (4), skin is 40-60 purpose stainless (steel) wires (5).
