Description

A forced push chute

technical field

The invention relates to the technical field of sintering material conveying equipment, in particular to a forced material pushing chute.

Background technique

During the design of the sintering plant, the sintering bulk materials are generally collected through the ash hopper or the funnel of the tape machine, and then transported to the designated place through the chute. However, sometimes due to limited space, the angle of the designed and installed chute is not enough or the characteristics of the material are unstable, it is easy to accumulate material, sticky material, and block the material after a long time, and even the inclination of the chute is not enough to completely discharge the material, resulting in the failure to use the chute. This kind of bulk slips. This leads to the requirement of raising the design height or adopting other means to solve the shortage of space, which greatly increases the cost of design or transformation, which leads to an increase in the investment cost of the project. In addition, if the design is relatively limited in the case of insufficient space, once material accumulation, sticky material, or material blocking occurs, it will not only seriously affect the production efficiency, but also increase the production and maintenance costs of the enterprise to a certain extent;

Detailed ways

As shown in Figure 1, a forced pusher chute includes a front end fixed section 2, which is composed of two straight pipes with an obtuse angle α, and the vertically arranged upper straight pipe is used to connect to the material outlet, such as sintering The outlet of the bulk material bin, the outlet of the funnel at the head of the tape machine or other material interfaces that need to be collected and slipped (such as the funnel-shaped discharge port 11 shown in Figure 1), can be specifically at the upper end of the upper straight pipe of the front fixed section 2 A connecting flange 1 is fixed; a cylindrical fixed cover 5 is fixed at the lower end of the lower straight pipe of the front end fixed section 2, and a rotating cylinder 6 is connected to it for rotation inside. 6. The transmission connection is used to drive the rotating cylinder 6 to rotate. The inner wall of the rotating cylinder 6 is provided with a spiral guide strip 7 for pushing the material downward when rotating. The spiral guide strip 7 should be made of wear-resistant material. Specifically, the spiral guide strip 7 The strip 7 can be a whole sheet-like spiral welded on the inner wall of the rotating cylinder 6, and its width is not greater than the radius of the rotating cylinder 6; since the rotating cylinder 6 is constantly rotating, the spiral material guide strip 7 is continuously pushed, and the material will not accumulate. Sticky material, material blocking and other phenomena, so the angle between the two straight pipes of the front fixed section 2 can be set smaller, which is beneficial to the installation in the case of insufficient space; a vibrator 10 is arranged at the lower end of the lower straight pipe of the front fixed section 2 , to prevent the material from stagnating in the lower straight pipe. Preferably, the vibrator 10 can be located directly below the side of the upper straight pipe of the front fixed section 2 away from the side of the rotating cylinder 6 to avoid material accumulation here. In actual work, when the angle α When it is smaller than the natural accumulation angle of the material being slid, the problem of insufficient α angle caused by insufficient space can be solved by the vibrator 10 .

The upper end of the fixed cover 5 can be fixed at the outlet of the lower straight pipe of the front end fixed section 2, and the fixed cover 5 and the rotating cylinder 6 can be set to be collinear with the center line of the lower straight pipe of the front fixed section 2.

The inner wall of the front end fixed section 2 is provided with a wear-resistant liner 3, and the discharge point of the front end fixed section 2 is in the rotating cylinder 6. Specifically, the inner diameter of the wear-resistant liner 3 can be made smaller than the rotating cylinder 6, and can be extended to Within the end of the rotating cylinder 6, other common ways can also be adopted to realize.

In a preferred embodiment, the connection between the front end fixed section 2 and the fixed cover 5 is provided with a connecting section 4 for fixed connection. The connection method can be flange connection, bolt connection or welding. Preferably, the connection section The inner diameters of both ends of 4 are respectively equal to the outer diameters of the front fixed section 2 and the fixed cover 5; in addition, the reason why the front fixed section 2 is separated from the fixed cover 5 is for the convenience of adjustment, if any inappropriate situation occurs, just replace the front fixed section 2 The angle can be adjusted, and the wear-resistant liner 3 is also more convenient to replace.

The above-mentioned driving device 8 can adopt the following method: comprising a motor (generally adopting a reduction motor) and gears, wherein the outer wall of the rotating cylinder 6 is fixed with a circle of driven gears (not in contact with the fixed cover 5), and the motor can be fixed on the fixed cover 5 Outer wall or inner wall, motor shaft end is provided with driving gear (if it is outer wall, then the fixed cover 5 at driving gear place needs opening), and it is connected with driven gear tooth; Driving device 8 also can adopt other modes certainly, for example does not adopt Tooth connection but belt drive etc.

In a preferred embodiment, bearings 9 are provided on the outer peripheries of both ends of the rotating cylinder 6 respectively, and the rotating cylinder 6 is rotationally connected with the rotating cylinder 6 through the bearings 9 .
