[0004] The two connection modes have the following problems: the bolt fastening connection mode is generally used for lifting by lifting equipment due to the large weight and volume of the analyzer, the bolt connection operation part is convenient, the installation needs to be completed by multiple people, the installation is inconvenient, in addition, the number of bolts is large, the installation position is high, and the bolt fastening is time-consuming and laborious; and the steel frame support soft connection mode needs to design and install a steel frame separately, and the manufacturing and installation cost is high.

[0005] Therefore, it is of great significance to study a simple flange installation method for pendulum type flour mill, which can reduce the installation and maintenance cost of the pendulum type flour mill. INVENTION CONTENTS

[0006] The utility model aims at solving the above problems, and provides a simple flange installation method for pendulum type flour mill.

[0007] The technical scheme of the utility model is:

[0008] A simple flange installation method for pendulum type flour mill is composed of a flange bottom plate and a flange side plate, wherein the flange bottom plate is a circular ring structure, a through hole is arranged in the middle, and a flange side plate is arranged on both sides of the circular ring type flange bottom plate; a rubber pad is arranged between the flange bottom plate and the flange side plate, the upper part of the rubber pad is an analyzer lower flange, and the lower part of the flange bottom plate is connected with a middle machine body barrel.

[0009] The diameter of the through hole of the flange bottom plate is 20-200mm.

[0010] The flange bottom plate and the flange side plate are integrally cast or integrally welded; and the simple flange installation method composed of the flange bottom plate and the flange side plate is welded on the middle machine body barrel.

[0011] The flange bottom plate is connected with the middle machine body barrel through the reinforcing ribs.

[0012] The utility model has the advantages that:

[0013] 1. The simple flange can effectively reduce the difficulty of field installation and reduce the number of installers.

[0014] 2. The simple flange connection does not require steel support, which can reduce the manufacturing cost of the swing mill. BRIEF DESCRIPTION OF DRAWINGS

[0019] The technical scheme of the utility model will be further described in combination with the embodiments shown in the drawings.

[0020] A simple flange 3 for a swing mill mainly consists of a flange bottom plate 10 and a flange side plate 9, wherein the flange bottom plate 10 is a circular ring structure with a through hole in the middle, and flange side plates 9 are arranged on both sides of the circular ring type flange bottom plate 10; and a rubber pad 4 is arranged between the flange bottom plate 10 and the flange side plate 9, and the rubber pad 4 is above the lower flange 6 of the analyzer; the flange bottom plate 10 is connected below the middle machine body cylinder 7.

[0021] Further, the diameter of the through hole of the flange bottom plate 10 is 20-200mm.

[0022] Further, the flange bottom plate 10 and the flange side plate 9 are casted as a whole, or the flange bottom plate 10 and the flange side plate 9 can be welded as a whole. The simple flange 3 composed of the flange bottom plate 10 and the flange side plate 9 is welded on the middle machine body cylinder 7, and more preferably, the flange bottom plate 10 is connected with the middle machine body cylinder 7 through the reinforcing rib 8, which can be fixed by the reinforcing rib 8 to increase the strength.

[0023] The principle of the utility model is:

[0024] A simple installation flange 3 is arranged on the outer edge of the support flange above the middle of the pendulum mill, and a circular ring structure with a diameter of 20-200mm is arranged on the simple installation flange 3, the analysis machine 5 is placed on the simple installation flange 3, the flange side plate 9 on the outer edge of the simple installation flange 3 can limit the horizontal displacement of the lower flange of the analysis machine, the analysis machine and the middle machine body are connected to each other by the weight of the analysis machine, and the rubber pad 4 with elasticity is arranged between the support flange of the middle machine body and the lower flange of the analysis machine, so that the sealing and damping effects are achieved.

[0025] The specific use mode of the pendulum mill is as follows: when the pendulum mill is installed, the middle machine body 2 is installed on the flange above the volute 1 after the volute 1 is installed, the rubber pad 4 is placed on the simple installation flange 3, then the analysis machine 5 is hoisted to the middle machine body 2, and then is placed on the outer edge of the lower flange 6 of the analysis machine, is pushed into the inner side of the flange side plate 9, and then falls, the lower flange 6 of the analysis machine is placed on the rubber pad 4, then the direction of the analysis machine 5 is adjusted, the analysis machine 5 is installed and connected by relying on the weight, the flange bottom plate 10 plays a supporting role for the analysis machine 5, and the flange side plate 9 plays a role in limiting the horizontal movement of the analysis machine 5.
