Description

Technical Field

[0001] This utility model relates to the field of general connectors, and in particular to a connection mechanism between a centrifuge and a feed hopper. Background Technology

[0002] Centrifuges play a crucial role in many production fields. For example, in the coal-water separation process, centrifuges are needed to separate coal lumps and slurry containing coal dust. The separated slurry enters the feed tank for secondary treatment, such as filtration.

[0003] Centrifuges and feed hoppers are often connected using a rigid connection. This method has two drawbacks: first, the slurry may dry and harden, causing pipe blockage; second, the centrifuge generates continuous vibration during operation, which can lead to damage to the connecting pipes and joints after prolonged use. To address this issue, current technology involves directly inserting the centrifuge's discharge pipe into the feed hopper's connection port, leaving a gap between the pipe and the port. However, this movable connection method allows material to leak through the gap, causing site contamination and making cleanup more difficult. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a centrifuge-material box connection mechanism that is simple in structure, quick to assemble, can ensure sealed material conveying between the centrifuge and the material box, is not easy to block the pipe, and has a longer service life.

[0005] The equipment includes two flange joints, and an elastic expansion joint is provided between the two flange joints.

[0006] The effect achieved is that the two flange joints are respectively encapsulated at the centrifuge outlet and the feed inlet of the hopper. The elastic expansion pipe in the middle can overcome the problem of material conveying pipe damage or short service life caused by centrifuge vibration based on its elastic deformation or expansion margin. In particular, when material dries on the inner wall of the pipe, it can be directly knocked and rubbed from the outside to separate the dried material from the pipe wall and avoid pipe blockage.

[0007] The beneficial effects of this utility model are: This utility model solves the problem that the connecting pipe between the centrifuge and the material box is prone to damage and has a short service life in the prior art. Moreover, unlike the movable connection method, it realizes the connection between the two chambers through the elastic telescopic pipe. In particular, the multi-transition connection section of the flange joint, together with the assembly ring groove, achieves the effect of quick assembly and easy maintenance.

[0014] Reference Figure 1 , Figure 2 The centrifuge and feed box connection mechanism of this utility model includes two flange joints 1, and an elastic telescopic pipe 2 is provided between the two flange joints 1.

[0015] The effect achieved is that the two flange joints 1 are respectively encapsulated at the centrifuge outlet and the feed inlet of the hopper. The elastic telescopic pipe 2 set in the middle can overcome the problem of material conveying pipe damage or short service life caused by centrifuge vibration based on its elastic deformation or telescopic margin. In particular, when material dries on the inner wall of the pipe, it can be directly knocked and rubbed from the outside to separate the dried material from the pipe wall and avoid pipe blockage.

[0016] Example 1: The flange joint 1 includes a rectangular flange 11, with encapsulation holes arrayed at its corners and a material channel in its center;

[0017] It extends integrally from its material channel and is provided with a transition connecting section 12 that transitions from square to round;

[0018] At the port of the transition connection section 12, a circular tube-shaped connecting pipe section 13 is integrally extended.

[0019] This achieves the effect of adapting to the conventional interfaces of centrifuges and material bins, as well as common round pipes, and enabling rapid assembly through flange joint 1.

[0020] In Example 2, the connecting pipe section 13 is provided with a concave assembly ring groove 131, the elastic telescopic pipe 2 is sleeved on the connecting pipe section 13, and is sealed at the assembly ring groove 131 using a clamp or snap ring.

[0021] This achieves the effect of facilitating rapid assembly and ensuring a good seal.

[0022] In Example 3, the elastic expansion pipe 2 is a corrugated pipe or a round pipe.

[0023] Furthermore, when the elastic telescopic pipe 2 is a circular pipe, the elastic telescopic pipe 2 is integrally injection molded from an elastic material.

[0024] The effect achieved in this way is to facilitate quick assembly and disassembly.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
