Description

Technical Field

[0001] This utility model relates to the field of slag ditch technology, specifically to a slag ditch structure for blast furnace slag and iron processing. Background Technology

[0002] The existing blast furnace slag outlets are subject to rapid flow of high-temperature molten slag, which erodes the slag channel spout, causing the insulation material of the slag channel to be lost and damaging the base of the slag channel. Furthermore, the existing slag channel structure is generally a monolithic cast-in-place structure, which is not convenient for maintenance and replacement. Utility Model Content

[0003] The technical problem this invention aims to solve is that the existing slag chute spout is greatly affected by scouring, which easily causes deformation of the slag chute substrate and makes slag chute repair difficult.

[0004] To solve the above problems, the technical solution adopted by this utility model is a slag trough structure for blast furnace slag and iron processing, including a U-shaped trough, which is installed in a channel on the ground. A water flow channel is opened on the lower side of the channel. A chute structure is provided at one end of the U-shaped trough. The chute structure includes a bottom chute and a top chute. A baffle is fixed at the top of the bottom chute, and a snap-fit ​​plate is fixed below the baffle. A second baffle is fixed at the top of the top chute, and a snap-fit ​​plate is fixed below the second baffle.

[0005] As a further embodiment of this utility model: a snap-fit ​​groove is provided on the upper side of the ground at both snap-fit ​​plate one and snap-fit ​​plate two, for fixing the positions of the bottom chute and the top chute.

[0006] As a further embodiment of this utility model: Baffle 1 and Baffle 2 have acute angles with the side of the bottom chute and the side of the top chute, respectively. The angle between Baffle 2 and the side of the top chute is greater than the angle between Baffle 1 and the side of the bottom chute, which facilitates the flow of molten iron.

[0007] As a further embodiment of this utility model: two lifting lugs are symmetrically fixed on the upper side of the baffle one, and a lifting lug two is fixed in the middle of the upper side of the baffle two, which facilitates the replacement of the bottom layer spout or the top layer spout.

[0008] As a further embodiment of this utility model: Baffle one is supported on the upper side of the U-shaped groove, and baffle two is supported on the upper side of baffle one, forming a superimposed structure with multiple layers of protection to ensure the service life of the groove.

[0009] As a further embodiment of this invention, both the bottom and top spouts are coated with a fire-resistant coating to improve fire resistance and increase service life.

[0010] Compared with the prior art, the advantages of this utility model are: this patent adds a double-layer chute structure, which can form protection at the original chute in the slag ditch, and the structure is simple and easy to replace. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0021] Combined with appendix Figure 1-5It can be seen that the device includes a U-shaped groove 1, which is embedded in a channel 2 on the ground. A water channel 3 is provided on the lower side of the channel 2 to cool one end of the U-shaped groove 1, preventing excessive heat concentration at one end of the U-shaped groove 1 from causing deformation. One end of the U-shaped groove 1 is equipped with a chute structure, which includes a bottom chute 4 and a top chute 5. A baffle 4.1 is fixed to the top of the bottom chute 4, and a snap-fit ​​plate 4.2 is fixed to the lower side of the baffle 4. A second baffle 5.1 is fixed to the top of the top chute 5, and a snap-fit ​​plate 5.2 is fixed to the lower side of the baffle 5. The baffle 4.1 and the second baffle 5.1 are respectively attached to the side of the bottom chute 4 and the side of the top chute 5. The surface has an acute angle, and the angle between the side of the baffle 2 5.1 and the side of the top chute 5 is greater than the angle between the side of the baffle 1 4.1 and the side of the bottom chute 4, which facilitates the flow of molten iron. Two lifting lugs 1 4.3 are symmetrically fixed on the upper side of the baffle 1 4.1, and lifting lugs 2 5.3 are fixed in the middle of the upper side of the baffle 2 5.1, which facilitates the replacement of the bottom chute 4 or the top chute 5. The baffle 1 4.1 is supported on the upper side of the U-shaped groove 1, and the baffle 2 5.1 is supported on the upper side of the baffle 1 4.1, forming a superimposed structure with multiple layers of protection to ensure the service life of the channel 2. The upper sides of the bottom chute 4 and the top chute 5 are coated with a refractory coating 7 to improve fire resistance and increase service life.

[0022] Combined with appendix Figure 5 It can be seen that there are snap-fit ​​grooves 6 on the upper side of the ground at the snap-fit ​​plate 4.2 and snap-fit ​​plate 5.2, which are used to fix the positions of the bottom chute 4 and the top chute 5.

[0023] The working principle of this application is as follows: When installing the chute structure, firstly, the bottom chute 4 is placed in the U-shaped groove 1 and fixed in position by snapping it into the snapping groove 6 using snapping plate 4.2. Then, the top chute 5 is placed in the bottom chute 4 and fixed in position by snapping it into another snapping groove 6 using snapping plate 5.2. Then it can be used. In practical applications, the top chute 5 usually reaches the end of its service life first. The top chute 5 can be removed and replaced with a new top chute 5 by hooking the lifting lug 5.3 with a hook.

[0024] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
