Abstract

The utility model discloses a novel sintering mixer water feeding device, which comprises a water pipe mounted on a support. A control valve is mounted on the water pipe, a free end of the water pipe extending outwards from the support is sealed, nozzles inclined to the free end of the water pipe are alternately uniformly disposed on the bottom face of the water pipe between the free end of the water pipe and the support, and an included angle formed between the nozzle below the free end of the water pipe and the horizon is smaller than that formed between the nozzle close to the support and the horizon. Water fed on a material face of a mixer by the novel sintering mixer water feeding device is in linear uniform distribution, thereby solving the problems of pointed non-uniform distribution of water feeding of an original device and severe material adhesion of a cylinder, and simultaneously reducing expenses on fabrication, maintenance and installation.

Description

A new type of water adding device for sintering mixer

technical field

The utility model relates to a water adding device for steel plant production, in particular to a new type of water adding device for a sintering mixer.

Background technique

In the production process of the mixer used in the iron and steel plant, it is necessary to continuously spray water on the barrel of the sinter mixer to prevent sticking. The distribution of water adding points in the existing water spraying device is not uniform, and the amount of water varies, which leads to serious sticking of material in the barrel of the sintering mixer and increases the maintenance cost.

Utility model content

The purpose of this utility model is to provide a new type of water adding device for a sintering mixer. The water added to the material surface of the mixer by the device is linearly and evenly distributed, which solves the problems of uneven distribution of water adding points and serious sticky material in the cylinder of the original device. , while also reducing production, maintenance and installation costs.

The purpose of this utility model is achieved in this way: a new type of sintering mixer water adding device, including a water pipe installed on the support frame, a control valve is installed on the water pipe, and the free end of the water pipe extending outward from the support frame is closed. From the free end of the water pipe to the bottom surface of the water pipe between the support frame, there are evenly distributed nozzles inclined to the free end of the water pipe, and the angle formed between the nozzle below the free end of the water pipe and the horizontal plane is smaller than that between the nozzle near the support frame and the horizontal plane angle formed between.

Adopting the water adding device of the utility model, since the angle formed between the nozzle located below the free end of the water pipe and the horizontal plane is smaller than the angle formed between the nozzle close to the support frame and the horizontal plane, so that the water is sprayed from the water pipe onto the material surface of the mixer. The water is linearly and evenly distributed, which solves the problems of uneven distribution of water adding points and serious sticky material in the cylinder of the original device, and also reduces the cost of production, maintenance and installation.

The utility model has a simple structure and is easy to manufacture. Since the included angle between the nozzle and the horizontal plane decreases regularly, the amount of water sprayed from the nozzle can adapt to the distance difference between the sintering mixer barrel and the water pipe, effectively improving the Water spray effect.

Description of drawings

The utility model will be further described below in conjunction with accompanying drawing.

Accompanying drawing is the front view structure schematic diagram of the utility model.

Detailed ways

A new type of water adding device for sintering mixer, as shown in the accompanying drawings, includes a water pipe 3 installed on a support frame 4, and a suspension steel wire rope 1 is connected to the free end of the water pipe 3. A control valve 5 is installed on the water pipe 3, and the control valve 5 is an automatic regulating valve for water volume. The free end of the water pipe 3 extending outward from the support frame 4 is closed, and the nozzles 2 arranged obliquely to the free end of the water pipe are evenly distributed on the bottom surface of the water pipe 3 between the free end of the water pipe 3 and the support frame 4, and are located in the water pipe. 3 The angle formed between the nozzle 2 below the free end and the horizontal plane is smaller than the angle formed between the nozzle 2 near the support frame 4 and the horizontal plane.

The water outlet at the lower end of the nozzle 2 is flattened into a duckbill shape, so that the sprayed water is distributed in a fan shape, and the water spray effect is improved.

The length of the nozzle 2 is 80mm, and the width of the water outlet at the lower end of the nozzle 2 is 3-5mm.

As shown in the figure, there are 8 nozzles 2, the angle between the nozzle 2 located below the free end of the water pipe and the horizontal plane is 40°, and the angle between the nozzle 2 near the support frame 4 and the horizontal plane is 75° , the angle between adjacent nozzles 2 and the horizontal plane differs by 5°, that is, the angle between the nozzle 2 below the free end of the water pipe 3 and the horizontal plane is 40°, and the angle between the nozzle behind the nozzle 2 and the horizontal plane The included angle is 45 °, and the included angle between the next nozzle 2 and the horizontal plane is 50 °, until the last one, the included angle between the nozzle 2 near the support frame 4 and the horizontal plane is 75 °.
