Description

Technical Field

[0001] The utility model relates to the field of slag coolers, in particular to a water inlet and outlet device of a slag cooler. Background Art

[0002] The slag cooler is mainly composed of an inner and outer double-layer sealing sleeve with fixed spiral blades welded on the inner cylinder, a slag inlet and outlet device, an exhaust device, a water inlet and outlet device, a transmission device, a base and other systems. When the slag cooler is driven by the transmission device to rotate slowly, the high-temperature slag discharged from the boiler is guided forward by the spiral blades in the inner cylinder of the sleeve, and the cooling water flows in the jacket between the inner and outer cylinders in reverse to take away the heat. The cooling wind also continuously passes through the inner cylinder of the jacket to take away the heat, so that the hot slag is gradually cooled. For the slag cooler, the water inlet and outlet device is an important component of the slag cooler, and the cooling water needs to pass through the water inlet and outlet device to cool the slag.

[0003] For example, a water inlet and outlet device for a slag cooler with a publication (announcement) number of CN206989231U includes a water inlet joint and a water outlet joint respectively connected by a connecting joint, the outer end of the water inlet joint is connected to a metal hose connected to an external water pump, the outer end of the water outlet joint is connected to a metal hose connected to an external water pump, gaskets are provided between the water inlet joint and the metal hose, and between the water outlet joint and the metal hose, infrared light-emitting tubes and receivers corresponding to the infrared light-emitting tubes are provided inside the water inlet joint and the water outlet joint, the infrared light-emitting tube and the receiver circuit are connected to a controller provided outside the water inlet joint and the water outlet joint, and a pressure gauge is also connected to the lower end of the water inlet joint, and the pressure gauge is connected to the controller circuit. The water inlet and outlet device for the slag cooler allows cooling water to enter the slag cooler from the water inlet joint and then flow out of the slag cooler from the water outlet joint, taking away the heat of the slag cooler during operation and cooling the slag cooler, but because the temperature of the cooling water will rise after flowing through the slag cooler, the cooling effect of the cooling water is reduced and the number of cycles is reduced.

[0004] Therefore, a slag cooler water inlet and outlet device has been developed to reduce the temperature of cooling water so as to improve the refrigeration effect and the number of circulation times of cooling water. Utility Model Content

[0007] Furthermore, flanges are provided on both the feed end connecting pipe and the discharge end connecting pipe.

[0008] Furthermore, it also includes a water outlet pipe, which is connected to the right side of the guide pipe. When the cooling water becomes hot and needs to be replaced, the cooling water flows to the discharge end connecting pipe and then flows out from the water outlet pipe.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

Flanges are provided on the feed end connecting pipe 3 and the discharge end connecting pipe 4 to facilitate docking of pipelines. The guide pipe 6 is provided with a control mechanism 7, and the guide pipe 6 is also provided with a cooling mechanism 8.

[0021] When using the utility model, first connect the feed end connecting pipe 3 and the discharge end connecting pipe 4 to the feed end and the discharge end of the slag cooler respectively, and then pass cooling water into the water inlet pipe 1, so that the cooling water enters the cooling system of the slag cooler from the feed end connecting pipe 3 to cool the slag cooler. After the cooling water flows through the slag cooler, the cooling water is made to flow from the discharge end connecting pipe 4 into the guide pipe 6 through the water pump 2 for recycling. When the cooling water becomes hot and needs to be replaced, the cooling water is made to flow to the discharge end connecting pipe 4, and then the cooling water is made to flow out from the water outlet pipe 5.

[0023] The cooling water can be cooled by using the cooling mechanism 8 of the device. The joint 83 is connected to the refrigerator. When the cooling water flows back into the guide pipe 6, the refrigerator is started so that the cooling pipe 82 is cooled on the fixed cover 81, thereby cooling the cooling water to improve the cooling effect and the number of cycles of the cooling water.
