Description

Connection structure for dry quenching rotary sealing valve of tamping coke oven

technical field

The utility model relates to a connection structure, in particular to a connection structure for a dry quenching rotary sealing valve of a tamping coke oven, which belongs to the technical field of metallurgical production equipment manufacturing.

Background technique

The function of the soft connection between the vibrating feeder and the rotary sealing valve is mainly to leave space for the vibrating feeder to move, and at the same time play a role of sealing. Due to the high temperature of the coke discharged from CDQ in the tamping coke oven, higher requirements are put forward for the soft connection material and quality here. Once the soft connection here leaks during the production process, it is almost impossible to fill the leak online. Because in the production process, a large amount of high-temperature dust is often generated due to the leakage of the soft connection, which makes it impossible for maintenance personnel to approach, and at the same time, a large amount of dust brings great pressure to the environmental protection work of the enterprise.

Utility model content

The technical problem to be solved by the utility model is to provide a connection structure for tamping coke oven CDQ rotary sealing valve which is not prone to high-temperature CDQ leakage dust during use.

The technical solution adopted to solve the above technical problems is: the connection structure used for tamping coke oven dry quenching rotary sealing valve, including two input ports respectively connected with the output port of the rotary sealing valve and the external vibrating feeder The connecting flange connected to the port also includes a flexible rubber connecting body lined with a wear-resistant plate on the inner side, and the two connecting flanges are connected as a whole through the flexible rubber connecting body.

Further, a thermal insulation filler is also filled between the wear-resistant plate and the flexible glue connecting body.

Further, the projections of the connecting flange and the flexible colloidal connecting body in its cross-section are mutually compatible square structures, and the four corners of the square structure are transitional arcs R not less than 280 mm arc transition structure.

Further, the flexible glue connecting body and the connecting flange are all fastened and connected by flanging glued bead.

The beneficial effect of the utility model is that: since the two connecting flanges are connected as a whole through the flexible colloidal connecting body, a layer is also lined inside the flexible colloidal connecting body Wear plate. In this way, not only the service life of the flexible connection structure is extended, but also during use, the flexible connection structure composed of the flexible colloidal connection body will not leak due to the existence of high-temperature CDQ dust, In this way, the safety of the operators is guaranteed, and the environmental protection work of the enterprise will not be brought pressure.

The marks in the figure are: connecting flange 1, wear-resistant plate 2, flexible glue connecting body 3, heat insulation filler 4.

Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, it is a connection structure for tamping coke oven CDQ rotary sealing valve that is not prone to high-temperature CDQ leakage dust during use provided by the utility model. The connecting structure includes two connecting flanges 1 respectively connected to the input port of the external vibrating feeder and the output port of the rotary sealing valve, and also includes a flexible rubber connecting body 3 lined with a wear-resistant plate 2 on the inner side , the two connecting flanges 1 are connected as a whole through the flexible glue connecting body 3 . Since the two connecting flanges 1 are connected as a whole through the flexible glue connecting body 3 , a wear-resistant plate 2 is also lined inside the flexible glue connecting body 3 . In this way, not only the service life of the flexible connection structure formed by the flexible colloidal connecting body 3 is prolonged, but also the flexible colloidal connecting body 3 will not be damaged due to the existence of high-temperature CDQ dust during use. The formed flexible connection structure leaks, which not only ensures the safety of the operator, but also does not bring pressure to the environmental protection work of the enterprise.

In the above embodiment, in order to further prolong the service life of the flexible rubber connecting body 3 , a thermal insulation filler 4 is also filled between the wear-resistant plate 2 and the flexible rubber connecting body 3 . Simultaneously, in order to make the connection structure convenient to be compatible with the input port of the external vibrating feeder and the output port of the rotary sealing valve, the connecting flange 1 and the flexible colloidal connecting body 3 are connected between them. The projections in the cross section are all set as a square structure that fits each other, and the four corners of the square structure are set as a circular arc transition structure with a transition arc R not less than 280mm. In this way, it not only facilitates the cooperation of the connection structure with the input port of the vibrating feeder and the output port of the rotary sealing valve, but also buffers the friction between the four side walls constituting the flexible colloid connector 3. stress, avoid shrinkage tearing, and achieve the purpose of prolonging the service life of the flexible colloidal connector 3 .

In the above embodiment, in order to facilitate design and manufacture, the two connecting flanges 1 are also designed as steel connecting flanges with reference to the existing structure. In order to facilitate the connection between the flexible rubber connecting body 3 and the steel For the connection between the connecting flanges, both the flexible glue connecting body 3 and the connecting flange 1 are provided with a flanging glued bead fastening connection structure. The fastening and connection structure of the flanging glued bead is shown in Figure 3. There is a flanging straight section at both ends of the flexible colloid connecting body 3, so that the two ends of the flexible colloid connecting body 3 It can be connected with the connecting flange 1 through the straight flanging section, bead and bolt.
