[0002] With the development of modern industry, the impact of dust on the environment and human health is becoming increasingly serious. In recent years, the country has paid more and more attention to environmental protection and global warming is serious. In order to advocate energy conservation and carbon reduction, the environmental protection industry has flourished. In order to maintain a clean production environment, it is necessary to clean up dust-contaminated places in a timely manner and promote a dust-free working environment. In addition, with the development of modern industry, the impact of dust on the environment and human health is becoming increasingly serious. Effectively controlling dust pollution and purifying the living environment of mankind has become a consensus of everyone. Dust removal equipment is a commonly used equipment in industrial production. It is used to remove dust and particulate matter generated in the industrial production process to purify the atmospheric environment. During operation, the discharged gas needs to be discharged through a pipeline connection. Therefore, the quality and method of the pipeline connection directly affect the overall performance of the dust removal equipment.

[0003] Commonly used pipe connection methods for dust removal equipment include: flange connection, threaded connection, groove connection (clamp connection), direct welding, compression connection, sleeve connection, etc. Flange connection is suitable for pipelines with larger diameters, main roads connecting valves, water meters, water pumps, etc., as well as pipe sections that need to be frequently disassembled and repaired; threaded connection is suitable for galvanized steel pipes with a diameter less than or equal to 80mm and exposed pipes of steel-plastic composite pipes; groove connection (clamp connection) is generally galvanized steel pipes with a diameter greater than or equal to 50mm, suitable for fire water supply, air conditioning hot and cold water, water supply and other systems; direct welding is generally used for concealed pipes and pipes with larger diameters, generally non-galvanized steel pipes; compression connection: Thin-walled stainless steel pipes with a diameter less than or equal to 80mm often use compression connection, which is convenient to install, reliable and economical; sleeve connection is generally aluminum-plastic composite pipe or copper pipe.

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0018] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0019] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0020] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0023] Reference Figures 1 to 3 As shown, an embodiment of a high-sealing tube bundle for pipeline connection of the utility model comprises a rubber belt layer 1, an inner iron sheet layer 2 is arranged on the outside of the rubber belt layer 1, an outer iron sheet layer 3 is arranged on the outside of the inner iron sheet layer 2, two relative fixing structures 4 are extended from the outer iron sheet layer 3, an iron block 5 is arranged inside the fixing structure 4, and the fixing structures 4 are fixed by bolt assemblies 6.

[0024] From the inside to the outside, the tube bundle is composed of a rubber belt layer 1, an inner iron sheet layer 2, an outer iron sheet layer 3, an iron block 5, and a bolt assembly 6. The outer iron sheet layer 3, the iron block 5, and the bolt assembly 6 form a tightening mechanism. When the tube bundle is sleeved on the connection between the two pipes, the bolt assembly 6 is used to fix and tighten the outer iron sheet layer 3, thereby achieving the effect of fixing the pipe connection. The inner tin sheet layer and the rubber belt layer 1 are also tightened under the tightening effect of the outer iron sheet layer 3. The interface between the inner iron sheet layer 2 and the rubber belt layer 1 is designed to be serrated to leave a shrinkage margin to avoid internal extrusion deformation when the outer iron sheet layer 3 shrinks excessively, thereby affecting the sealing effect. The innermost part of the tube bundle is made of rubber to avoid hard connection and good sealing effect.

[0025] The materials of the inner iron sheet layer 2 and the outer iron sheet layer 3 are both galvanized iron sheets, which are corrosion-resistant.

[0026] The connection where the outer iron sheet layer 3 is rolled up is fixed with a bolt assembly 6, and the connection is thickened with a galvanized iron block 5 to play a reinforcing role and reduce the wear of the bolts and the outer iron sheet layer 3 during disassembly and installation.

[0027] The dimensions are as follows: the thickness of the outer iron sheet layer 3 is in the range of 1.4mm-1.6mm; the thickness of the inner iron sheet layer 2 is in the range of 1.1mm-1.3mm; the thickness of the rubber belt layer 1 is in the range of 2.9mm-3mm; and the angle between the two fixing structures 4 is 12°.

[0028] This structure does not require welding (protrusions) and has no flange steps. After the two pipes are butt-jointed, they form a smooth surface without impact / friction, which reduces the risk of sparks and is an important structure in explosion-proof design.

[0029] The above-described embodiments are only preferred embodiments for fully illustrating the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or changes made by technicians in the technical field on the basis of the present utility model are all within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the claims.
