Description

Technical Field

[0001] The utility model relates to the field of boiler slag removal, in particular to a boiler slag removal device. Background Art

[0002] When a boiler burns, ash and slag will be generated. In order to make the subsequent combustion more sufficient, it is necessary to clean the furnace ash. At present, the ash and slag are directly discharged through the ash outlet and conveyed by a conveyor belt. Since the ash and slag may contain other metal impurities and some large particulate substances that are not fully burned, it is necessary to transport them to a crusher for crushing. At the same time, there is also a certain amount of heat loss in the discharged ash and slag. Therefore, based on this technical problem, we designed a boiler slag removal device. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and meet the actual needs, providing a boiler slag removal device.

[0004] In order to achieve the purpose of the utility model, the technical scheme adopted by the utility model is: a boiler slag removal device, including a boiler slag outlet, a slag crushing tank and a slag crushing conveyor belt. A square slag crushing tank is arranged below the boiler slag outlet. A plurality of slag block blocking rods are arranged in an array at the bottom slot opening of the slag crushing tank. Below the slag block blocking rods, there is a slag crushing conveyor belt. The slag crushing conveyor belt and the bottom slot opening of the slag crushing tank are both arranged in a heat insulation bin made of metal material. A slag block crushing member is arranged in the slag crushing tank, and the slag block crushing member drives the crushing of slag blocks through a power device.

[0005] The slag block crushing member includes a slag crushing plate, a telescopic groove and a hydraulic cylinder. Telescopic grooves communicating with the slag crushing tank are arranged on both sides of the slag crushing tank. The slag crushing plate is telescopically arranged in the telescopic groove and can extend into the slag crushing tank during crushing. Two hydraulic cylinders are respectively arranged on both sides of the telescopic groove. The hydraulic rods of the hydraulic cylinders extend into the telescopic groove and are fixedly connected to the slag crushing plate on the same side.

[0006] A plurality of slag crushing columns are arranged in an array on the opposite sides of the two slag crushing plates. The slag crushing columns of the two slag crushing plates do not contact each other when clamping, and the end of the slag crushing column of one slag crushing plate can be attached to the other slag crushing plate when clamping.

[0007] A hot air suction hood is arranged above the heat insulation bin of the conveyor belt at the rear end of the boiler slag outlet. One side of the hot air suction hood is connected with a heat absorption pipe. The end of the heat absorption pipe is connected with a negative pressure fan. The middle part of the heat absorption pipe extends into a hot water suction tank. Water inlets and water outlets are respectively arranged on both sides of the hot water suction tank.

[0008] The heat absorption pipe extending into the hot water suction tank is arranged in a winding and swirling manner.

[0009] The beneficial effects of the present utility model are as follows:

[0010] This device can block large particle ash and slag through the ash blocking rod, and break and send out the ash and slag through the slag breaking plate and the staggered breaking rods, thus eliminating the need for subsequent installation of a crusher. The device uses air cooling to dissipate heat from the ash and slag, and the dissipated heat is recycled to reduce heat loss. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present utility model will be further described below in conjunction with the drawings and embodiments.
