Preferably, the protective layer is arranged on the inner wall of the avoiding notch and is formed by building bricks.

Preferably, the cross section of the avoiding notch is arranged in a square structure.

Preferably, the rigid coupling has inlet tube and outlet pipe on the water jacket main part outer wall, the inlet tube is located the well lower region of water pipe main part lateral wall in, and is connected with a plurality of distributing pipes on its lateral wall, the distributing pipe evenly distributed in dodge the both sides of notch, the inlet tube passes through outside circulating pump and outlet pipe intercommunication and forms the circulation water route.

Preferably, the side walls of the two sides of the water jacket main body are fixedly connected with drain pipes, the drain pipes are positioned in the area close to the bottom of the water jacket main body, and the drain pipes are connected with through-stop pieces for controlling the drain pipes to be opened and closed.

Preferably, the water jacket main body is provided in a bucket-shaped structure with a large top and a small bottom.

The technical effects of the utility model are that: 1. through the structural arrangement on the water jacket main body, the simplicity and low cost of the slag hole water jacket structure are ensured, the water jacket structure is suitable for different water jacket systems, and meanwhile, the avoiding notch can effectively avoid the slag hole of the smelting furnace, so that the slag hole of the smelting furnace is prevented from being contacted with the water jacket, the water jacket is protected from being damaged, and the normal operation of the water jacket system is ensured; in addition, dodge the inserting of notch also can guide the oxygen hose, take place the extrusion crooked when avoiding the oxygen hose to insert, guarantee to burn the correct of oxygen operation and go on, avoid extra occurence of failure.

2. Through the structure of the avoiding notch and the arrangement of the protective layer on the avoiding notch, the inner wall of the water jacket main body is protected from being damaged when the water jacket main body is burnt to the inner wall in oxygen burning operation, and the extra economic loss in the accident is further reduced; meanwhile, only the key part is provided with the protective layer, and the bottom surface of the water jacket does not need to be protected by all bricks, so that the materials are effectively saved, extra maintenance and overhaul are realized, and the use and maintenance cost is reduced; in addition, constitute the protective layer by the fragment of brick, receive the firing when causing the damage when the fragment of brick, the whereabouts can appear in the masonry, forms the self early warning feedback of cinder notch water jacket, and the staff can in time perceive the relevant condition and operate the loss stopping, the extra economic loss that probably appears when further reducing cinder notch accident and taking place.

3. Through the setting of inlet tube and distributing pipe can lead outside moisturizing to the both sides of dodging the notch to when avoiding and dodging the notch interference, guarantee that the cinder notch water jacket distributes evenly at the during operation feedwater, guarantee the cooling effect of cinder notch water jacket.

4. Through the setting of blow off pipe, regularly arrange the sewage in the slag notch water jacket, the difficult enrichment of guarantee water jacket main part bottom remains the calcium magnesium ion in the waste residue, guarantees the life of slag notch water jacket.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

The reference numerals of the main technical features in the figure are as follows: 1. a water jacket main body; 11. avoiding the notch; 2. a water inlet pipe; 3. a distribution pipe; 4. a sewage discharge pipe.

Detailed Description

The invention will be further explained by means of the following description and the attached drawings.

As shown in fig. 1, the novel slag hole water jacket for the smelting furnace comprises a water jacket main body 1, wherein the water jacket main body is in a bucket shape with a large upper part and a small lower part, an avoiding notch 11 is formed in the center of the bottom of the water jacket main body 1, the avoiding notch 11 is arranged in a square structure and is positioned right above a slag hole of the smelting furnace; bricks are laid on the inner wall of the avoiding notch 11 to form a protective layer to protect the inner wall of the water jacket main body 1 from being damaged.
