Description

Technical Field

[0001] The utility model relates to the field of discharge valve processing, in particular to a water-cooled star-shaped slag discharge device. Background Art

[0002] During the hazardous waste process, high-temperature slag is produced, usually at a temperature of 1100°C. These slags need to be effectively cooled and discharged to prevent damage to equipment and the environment. Currently, the commonly used slag discharge devices include water-sealed slag discharge devices and water-cooled jacketed slag discharge devices.

[0003] The slag produced by the water-sealed slag discharge device will contain a large amount of water, and subsequent drying equipment is required. When encountering salt-containing materials, the high-temperature salt will produce a violent chemical reaction when it comes into contact with water due to the high-temperature molten salt. This reaction will cause the salt to decompose rapidly in an instant, releasing a large amount of heat energy, and may even cause an explosion.

[0004] Commonly used water-cooled jacket slag discharge devices, such as Chinese patent CN113479612A, disclose a high-temperature air-locking discharge valve. This patent uses water to cool the shell and the main shaft so that the shell and the main shaft will not expand or deform under stress under high-temperature conditions. However, in the entire discharge process, there is another important component, the blade (flap), which will also come into contact with the high-temperature material, but this patent does not have a structure for cooling the blade. Utility Model Content

[0005] The utility model aims to provide a water-cooled star-shaped slag discharging device.

[0006] The innovation of the utility model lies in that: the application sets up a shell cooling cavity, a shaft cooling cavity and a plate cooling cavity to ensure that important components in contact with high-temperature materials have cooling structures, ensuring that these components are free from expansion agent stress deformation under high-temperature conditions, and the service life of the equipment is long.

[0007] In order to achieve the above utility model purpose, the technical solution of the utility model is:

The connecting ring pieces are uniformly distributed with through holes in the circumferential direction; the connecting ring pieces are arranged along the axial direction of the inner tube to divide the shaft cooling cavity into a first shaft cooling cavity close to the water inlet end and a second shaft cooling cavity close to the water outlet end; a first limiting guide hole is arranged on the outer wall of the first shaft cooling cavity, and a second limiting guide hole is arranged on the outer wall of the second shaft cooling cavity; a partition is arranged inside the flap to divide the inside of the flap into a first plate cooling cavity and a second plate cooling cavity; a plurality of through holes are arranged on one side of the partition close to the free end to connect the first plate cooling cavity with the second plate cooling cavity; the first plate cooling cavity corresponds to the first shaft cooling cavity and is connected through the first limiting guide hole; the second plate cooling cavity corresponds to the second shaft cooling cavity and is connected through the second limiting guide hole.

[0009] Furthermore, the interior of the inner shell has a structure that is larger at the top and smaller at the bottom.

[0010] Furthermore, reinforcing ribs are evenly distributed around the upper circumference of the outer wall of the shell.

[0011] Furthermore, reinforcing ribs are provided on the flap.

[0012] Furthermore, a water inlet pipe is arranged at the bottom of the side wall of the shell, and a water outlet pipe is arranged at the top of the opposite side wall.

[0013] The beneficial effects of the utility model are:

[0014] First: This application sets up a shell cooling cavity, a shaft cooling cavity and a plate cooling cavity to ensure that each component in contact with high-temperature materials has a cooling structure, ensuring that these components are free from expansion agent stress deformation under high-temperature conditions, and the service life of the equipment is long.

[0015] Second: This application sets a limiting guide hole between the shaft cooling cavity and the plate cooling cavity, and sets a perforation on the side close to the free end of the partition inside the flap, so that the direction of the coolant in the plate body forms an inverted U shape, ensuring that the coolant can flow smoothly between the rotating shaft and the flap, while also being able to quickly cool the rotating shaft and the flap. The structural design is ingenious and the cooling effect is good.

[0016] Third: The inner shell has a structure that is larger at the top and smaller at the bottom, which is convenient for locking out wind. BRIEF DESCRIPTION OF THE DRAWINGS
