Abstract

A heat preserving box for forming thermal insulation layers through outer wall assembly used for pipelines or equipment mainly includes a heat preserving box body approximately matched with an outer surface of a pipeline or equipment, wherein the heat preserving box body has two layers, namely, an inner layer and an outer layer; each layer is formed by stainless steel plates through welding or riveting; the inner and the outer layers are connected in a misplaced manner in axial and radial directions, so as to form misplaced layers with one convex and one concave in the two directions; uniformly distributed elastic sawtooth belts are embedded on the outer surface of the inner layer; a hasp for being connected with another heat preserving box body is arranged on a connecting edge of the outer surface of the outer layer; both the inner and the outer layers are hollow, form sealed spaces and are filled with at least one heat insulation cotton material layer or multilayers of anti-radiation stainless thin plate layers; and strengthening rib strips in the same direction or crossed strengthening rib strips are further arranged in the hollow spaces of the inner and the outer layers. The heat preserving box has the characteristics of simple structure, high intensity, convenience in use and installation, reliability, capability of greatly improving integral thermal insulation performance, and the like.

Description

A kind ofly be used for the incubation chamber that pipeline or equipment carry out outer wall assembly unit thermal insulation layer

Technical field

The utility model relates to a kind of incubation chamber that pipeline or equipment carry out outer wall assembly unit thermal insulation layer that is used for, the double-walled incubation chamber of the assembly unit thermal insulation layer that especially a kind of stainless steel material is made belongs to a kind of heat preservation module.

Background technique

Existing heat distribution pipeline or power equipment etc., need superscribe one deck thermal insulation layer at least at the outer wall of pipeline or equipment mostly, so that reduce the heat loss of heat distribution pipeline or power equipment, because these pipelines or equipment are in running, can produce a large amount of heats, cause the waste of energy.The most original heat preserving method is to adopt the outer wall at pipeline or equipment to be coated with the last layer thermal insulation layer, outwards distributes by outer wall to reduce heat; Though but this original heat preserving method is simple, heat insulation effect is very undesirable, still has the space that a large amount of heats distributes, and this method outward appearance is not attractive in appearance, removing is very difficult again, belongs to disposable use basically, and pipeline or equipment are produced harmful effect.

The splicing mounting types of the heat-preservating shell of the most employing of people now, promptly make Pork-pieces heat preservation module according to the size of pipeline or equipment in advance, then they are taken to the splicing that insulation block is carried out at the scene, the shell that common insulation block structure is made by glass fibre reinforced plastic material, internal fixation has thermal insulation layer from level to level, as thermal insulation layer made from asbestos etc.; Because the shell Heavy Weight that glass fibre reinforced plastic material is made, structure is hard and crisp, and comparatively difficulty is installed in splicing, and working life is short, and, because block insulation block after splicing, can stay splicing seams in splicing place, therefore cause thermal insulation property to reduce greatly.

Summary of the invention

The purpose of this utility model be to overcome prior art deficiency, and provide a kind of simple in structure, easy to install and use, reliable, can improve the incubation chamber that pipeline or equipment carry out outer wall assembly unit thermal insulation layer that is used for of integral heat insulation performance greatly.

The purpose of this utility model is finished by following technical solution, it mainly includes the insulation box body that coincide substantially with pipeline or device outer surface shape, described insulation box body has inside and outside two-layer, every layer forms by corrosion resistant plate welding or riveted joint, describedly inside and outsidely two-layerly is connected together and forms both direction each one protrudes a recessed dislocation layer that contracts with both direction dislocation axially and radially.

Stud with the uniform elasticity saw tooth belt of a rule on the described inner layer outer surface, the phase edge fit on the described outer outer surface is provided with the hasp that connects another insulation box body.

Described inside and outside layer is hollow and becomes sealed space, is filled with multilayer antiradiation Thin Stainless Steel flaggy in it.

Also be provided with the reinforced rib of a direction in the hollow space of described internal and external layer or be the reinforced rib of cross setting.

The utlity model has simple in structurely, intensity is big, and is easy to install and use, reliable, can improve characteristics such as integral heat insulation performance greatly.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is pipeline of the present utility model package assembly schematic representation radially when splicing and combining.

Fig. 3 is a kind of structural representation that axially splices and combines of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, incubation chamber described in the utility model, can be referred to as heat preservation module again, it mainly includes the insulation box body 1 that coincide substantially with pipeline or device outer surface shape, described insulation box body 1 has inside and outside two-

layer

11,12, every layer forms by corrosion resistant plate welding or riveted joint, described inside and outside two-

layer

11,12 with axial A and radially the dislocation of B both direction be connected together and form both direction each one protrudes 2, one recessed 3 the dislocation layer of contracting.

Internal layer shown in Fig. 1 studs with the uniform elasticity saw tooth belt 4 of a rule on outer 11 surfaces, and it can clamp the pipeline or the equipment of insulation better, and has constituted air heat insulating layer in the space of its formation, has reduced heat conduction loss, can further improve heat insulation effect.

Phase edge fit on the outer outer surface described in the utility model is provided with the hasp 5 that connects another insulation box body, as shown in Figure 2, the insulation box body 1 that adopts two semicircles is mutually to being connected into a pipe, the radial misalignments layer is just complementary mutually, form dislocation and join, and the connecting part overlaps thermal insulation layer that wraps up pipeline fully of back formation mutually with described hasp on the two incubation chamber volume surrounding outer surfaces that join.

Shown in Figure 3, with structural similarity shown in Figure 2, in the axial direction, be incubated the box body axial dislocation layer also just mutually complementation of back between them of joining in twos, and form axial dislocation and join, above-described dislocation is joined, and can eliminate the splicing seams that produces because of splicing between the two insulation box bodys well, increases its heat insulation effect.

Inside and

outside layer

11,12 described in the utility model is hollow and becomes sealed space, be filled with multilayer antiradiation Thin Stainless Steel flaggy in it, to increase effect of heat insulation, especially after having set up antiradiation Thin Stainless Steel flaggy, can significantly reduce thermal-radiating energy loss.

The utility model can also be provided with the reinforced rib of a direction or be the reinforced rib of cross setting in order to increase the intensity of insulation box body in the hollow space of described internal and external layer.
