Embodiment 1

[0011] Such as figure 1 The shown centrifugal fan base includes a base plate 1 and a mount 2 formed on the base plate 1. The mount base is equipped with a fan body 3 on the base plate 1 at the front end of the base body 2. The fan body 3 is in turn The reduction box 4 and the coupling 5 are connected to the motor 6, the reduction box 4 and the motor 6 are mounted on the base body 2 through bolts, the surface of the base body 2 is equipped with a first steel pipe 8, and the first steel pipe 8 is welded and fixed On the surface of the seat body 2, a second steel pipe 9 is installed at the port connection of the first steel pipe 8, one end of the second steel pipe 9 is welded to the port of the first steel pipe 8, and the other end is fixedly connected to the ground. The first steel pipe 8 and the second steel pipe 9 are round steel.

Embodiment 2

[0012] Embodiment 2: The first steel pipe 8 and the second steel pipe 9 are angle steel, and other features are the same as in Embodiment 1.

[0013] Since the first steel pipes 8 are respectively installed on the four surfaces of the base body 2, and the port connections of the first steel pipes are welded to connect the second steel pipes 9, the steel pipes 9 are fixedly connected to the ground, which increases the rigidity of the base body 2. After installing the centrifugal fan on the base of the centrifugal fan, the overall vibration is reduced; after a period of use, no bolts are loose or cracks appear on the front end of the mounting seat.

Abstract

The invention discloses a centrifugal fan base, and relates to the technical field of centrifugal fan manufacturing. The centrifugal fan base comprises an installing base composed of a bottom plate and base bodies arranged on the bottom plate. First steel pipes are arranged on the surfaces of the base bodies. Second steel pipes are arranged at the joints of the first steel pipes. One end of each second steel pipe is connected to the corresponding first steel pipe in a welding manner, and the other end of each second steel pipe is fixedly connected with the ground. Compared with the prior art, the centrifugal fan base can solve the problem that the rigidity of base bodies of an existing centrifugal fan is not enough.

Description

technical field [0001] The invention relates to the technical field of manufacturing a centrifugal fan, in particular to a base for a centrifugal fan. Background technique [0002] The centrifugal fan is one of the important parts of the clinker bulk system. There is a centrifugal fan, which includes a mounting seat composed of a bottom plate and a seat on the bottom plate. The mounting seat is located at the front end of the seat body The fan body is installed on the bottom plate, and the fan body is connected with the motor through a reduction box and a coupling in turn. The reduction box and the motor are both mounted on the base body through bolts, and the bottom plate is fixed through anchor bolts. on the ground. The rigidity of the seat body of this centrifugal fan is not enough, which leads to the following problems in the production process: 1. Due to the large vibration of the centrifugal fan during operation, resonance occurs in the machine room, which causes the ...
