Description

Technical field:

[0001] The utility model relates to the field of slag coolers, in particular to a feeding mechanism of a multi-tube slag cooler. Background technology:

[0002] The multi-tube slag cooler is a device for cooling slag, comprising a machine body, a feeding mechanism at the front end of the machine body, and a discharging mechanism at the rear end. Multiple slag discharge steel pipes with spiral blades are arranged in the machine body between the feeding mechanism and the discharging mechanism. There is cooling water in the space between the slag discharge steel pipes in the machine body. The rotation of the machine body drives the slag to move forward in the slag discharge steel pipe while the cooling water is used to cool the slag, and then the slag is discharged from the discharging mechanism.

[0003] The existing feeding mechanism includes a feeding pipe, which is cylindrical in shape. An end plate is fixed to the rear of the feeding pipe. The end plate has holes at positions corresponding to the slag discharge steel pipes. A spiral blade is fixed to the inner wall of the feeding pipe. The feeding mechanism rotates simultaneously with the machine body, and the spiral blade drives the material through the holes of the end plate and into each slag discharge steel pipe. Due to the angle of the spiral blades in the feeding pipe, the ability to transport slag is poor, and slag will accumulate in the feeding pipe. The temperature of slag is generally around 900°C. There is cooling water in the space between the feeding pipe and the machine body. Under the action of cooling water, the accumulated material is prone to coking, causing the material to be blocked in the feeding pipe, resulting in the inability to continue to transport the material and affecting production. In addition, the space between the outer wall of the feeding pipe and the machine body is small, resulting in a small amount of cooling water here, which affects the cooling effect of the slag. Summary of the invention:

[0004] The technical problem to be solved by the utility model is to provide a multi-tube slag cooler feeding mechanism which is not easy for materials to accumulate and has a good cooling effect.

[0005] The purpose of the present utility model is achieved as follows: it includes a feed pipe, which is conical, with the end of the feed pipe having a smaller diameter in front and the end having a larger diameter in the back. An end plate is fixed to the end having a larger diameter, and discharge holes are provided on the end plate at positions corresponding to the respective slag discharge steel pipes. A plurality of strip-shaped protrusions are welded on the inner wall of the feed pipe, and the feed pipe is fixed to the inner wall of the front end of the machine body.

[0006] The advantages of the utility model are: since the spiral sheet in the original feed pipe is cancelled, the cylindrical feed pipe is changed into a conical feed pipe, and strip-shaped protrusions are welded on the inner wall of the conical feed pipe, the conveying capacity is increased and the material is prevented from coking.

[0007] Because the feed pipe is conical, under the condition of the same size of the machine body, the space between the conical feed pipe and the inner wall of the machine body is larger than that of the cylindrical feed pipe, and the amount of cooling water there is large, which can improve the cooling effect.

[0011] Figure 4 It is a schematic diagram of the installation state of the utility model. Specific implementation method:

[0012] The following combination Figure 1-4 Further explain the utility model;

[0013] It includes a feed pipe 1, which is conical, with the end with a smaller diameter at the front and the end with a larger diameter at the back. An end plate 2 is fixed to the end with a larger diameter. The end plate is provided with discharge holes 3 at positions corresponding to each slag discharge steel pipe. Several strip-shaped protrusions 4 are welded on the inner wall of the feed pipe. The feed pipe is fixed on the inner wall of the front end of the machine body 5.

[0014] The material enters the feed pipe from the end with a smaller diameter, and then enters the slag discharge steel pipe of the multi-tube slag cooler through the discharge holes on the end plate.

[0015] Since the spiral sheet in the original feed pipe is cancelled and the cylindrical feed pipe is changed to a conical feed pipe, strip-shaped protrusions are welded on the inner wall of the conical feed pipe, which increases the conveying capacity and prevents the material from coking.

[0016] Because the feed pipe is conical, under the condition of the same size of the machine body, the space between the conical feed pipe and the inner wall of the machine body is larger than that of the cylindrical feed pipe, and the amount of cooling water there is large, which can improve the cooling effect.
