Technical Field
The utility model belongs to the technical field of the centrifugal fan, especially, relate to a detachable strutting arrangement of centrifugal fan casing.
Background
The centrifugal ventilator is a driven fluid machine which increases the pressure of gas and discharges the gas by means of input mechanical energy. Centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and draught of boilers and industrial furnaces, cooling and ventilation in air conditioning equipment and household electrical appliances, drying and sorting of grains, wind tunnel wind sources, inflation and propulsion of air cushion boats, and the like.
The larger the centrifugal fan, the less rigid it is and the more easily deformed, particularly the inlet box of the casing, so that it is necessary to increase the rigidity of the casing and prevent the deformation of the casing.
Chinese patent publication No. CN202789735U discloses a support pipe group for an air inlet box of a centrifugal fan casing, which includes an air inlet box, the support pipe group is disposed on the air inlet box, the support pipe group includes a protection ring and support pipes, the protection ring is disposed at two ends of the support pipes, and the number of the support pipe groups is one or more.
However, due to the limitations of manufacturing process and transportation size, the inlet box or volute of the large centrifugal ventilator casing is usually detachably connected by bolts, and needs to be transported to a user site for assembly, which requires that the casing support device also be detachable and assembled with the casing at the user site. The above patent is attached to the inlet box and cannot be assembled on site.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a detachable strutting arrangement of centrifugal fan casing to solve strutting arrangement among the prior art can not dismantle, can not the on-the-spot problem of assembling.
In order to achieve the above purpose, the technical scheme of the utility model is that: a detachable supporting device for a centrifugal ventilator shell comprises a supporting component, wherein the supporting component comprises a supporting tube, two connecting sleeves and two connecting plates, and two ends of the supporting tube are connected with the connecting plates through the connecting sleeves; the connecting plate is used for being installed on a panel of the air inlet box or a common side plate of the volute.
Furthermore, the two connecting plates are fixed on two sides of the air inlet box panel opposite to the volute common side plate or two sides of the two volutes common side plates opposite to each other in advance.
Further, gaps of 3 mm are reserved in installation sizes between the supporting tube and the connecting sleeve and between the supporting tube and the connecting plate.
Further, the supporting component is provided with a plurality of groups.
Further, the supporting tube is a cylindrical steel tube.
The working principle of the technical scheme is as follows: in the manufacturing process of the casing, two connecting plates of each group of supporting components are fixed on a panel of the air inlet box or a shared side plate of the volute according to preset positions, and the supporting tubes and the connecting sleeves are processed according to the size. When the standby shell is assembled after being transported to a user site, the connecting plates are used as positioning, the supporting pipes and the connecting sleeves are arranged at preset mounting positions, and the connecting sleeves are welded with the supporting pipes, the connecting sleeves and the connecting plates.
The beneficial effects of this technical scheme lie in: the technical scheme can well prevent the deformation of the shell, simultaneously increase the rigidity of the shell, and facilitate the assembly and welding with the detachable shell on the user site. Secondly, the supporting tube is made of steel tubes, the smooth round surface is favorable for airflow to pass through, the influence on the airflow is small, and the fixed supporting tube can prevent the shell from deforming. The connecting plate increases the contact area of the supporting tube and the connecting sleeve with the panel of the air inlet box or the volute sharing side plate, so that the supporting component can be stably welded inside the casing, and the acting force of the supporting tube is effectively transmitted to the casing. And fourthly, welding the connecting plate at a preset position on the panel of the air inlet box or the common side plate of the volute in the manufacturing process, so that the support tube and the connecting sleeve can be conveniently positioned and assembled and welded on the site of a user. In order to facilitate the assembly of the supporting component, gaps of 3 mm are reserved for the installation sizes of the supporting pipe, the connecting sleeve and the supporting pipe and the connecting plate.
