Problems solved by technology

[0003] At present, there are many schools of technology to prevent coal blocking, and various anti-blocking equipment are also widely used, but these technologies or equipment have a common feature, that is, single technology and single method, which cannot adapt to the current complex coal blocking on site The reason is that in the process of solving the problem of coal blocking, it is often to lose sight of the other, and the application effect is always unsatisfactory
Moreover, there are generally low work efficiency, or affect the peripheral equipment, or the equipment itself has a high failure rate and a large amount of maintenance, or cannot ensure 100% arch breaking or prevent sticking to the wall, etc. In short, the use effect is not satisfactory.

Embodiment 1

[0043] Such as figure 1 As shown, the ultrasonic phase-shifting vibrator 1 and the high-frequency electromagnetic vibrator 2 are respectively installed on the outer wall of the feeding pipe of the silo; the ultrasonic phase-shifting vibrator 1 includes an ultrasonic vibration transmission rod, an ultrasonic transducer, an ultrasonic special cable and Ultrasonic controller; the ultrasonic vibration transmission rod of the ultrasonic phase-shifting vibrator 1 can be directly welded on the outer wall of the silo blanking tube, or can be threaded through a special joint; when the inner wall of the silo blanking tube has a thin metal interlayer , the ultrasonic vibration rod should be directly connected with the internal thin-walled metal plate;

[0044] The high-frequency electromagnetic vibrator 2 is connected with the outer wall of the silo feeding pipe through the rapper bracket, and the rapper bracket 2.1 is welded on the outer wall of the silo feeding pipe; the impact head of...

Embodiment 2

[0053] On the basis of Embodiment 1, the arch breaker 3 also has an alternative structure, such as image 3 shown in figure 2 On the basis of the broken arch plate 3.5, a near-wall broken arch plate 3.8 is arranged, and the two ends of the near-wall broken arch plate 3.8 protrude and are similar to the inner wall of the silo blanking pipe; when working, it not only has a good arch-breaking function, but also It also has a good wall cleaning function.

Embodiment 3

[0055] On the basis of Embodiment 1, the installation method of the arch breaker 3 in the silo blanking tube is changed to use the support frame 4 to hoist the arch breaker 3 in the silo blanking tube. In the actual use process, the support frame 4 The installation position is the easiest place to bridge in the silo drop pipe;

[0056] Such as Figure 4 As shown, the arch breaker spreader 3.1 is connected to the support frame 4, and the support frame 4 includes a support center piece 4.1, a support piece 4.2, a support base 4.3, and a positioning piece 4.4; one end of the three support pieces 4.2 is movably connected with the support center piece 4.1, and the support The other end of the piece 4.2 is connected with the inner wall of the silo discharge pipe, and is supported at an equal angle; the end of the support 4.2 connected with the inner wall of the silo discharge pipe is provided with a support base 4.3, and the support base 4.3 is used for falling with the silo. The i...

Abstract

The invention discloses a device for efficiently preventing hopper material bridging and wall adhering. The device comprises an arch breaker arranged in a stock bin discharging pipe, the arch breakercomprises a vertical main beam, a plurality of horizontal supporting beams are arranged on the vertical main beam, and the horizontal supporting beams are evenly distributed on the surface of the vertical main beam with the vertical main beam as the circle center; an arch breaking plate is arranged at the ends of the horizontal supporting beams; and a vibration transmission device and a power source are further arranged on the vertical main beam, one end of the vibration transmission device is connected with the vertical main beam, and the other end of the vibration transmission device is connected with the power source. The device is low in energy consumption and remarkable and lasting in arch breaking and wall adhering preventing; the device is stable, safe and reliable in operation, theautomation degree is high, and unattended operation is achieved; and field installation and construction are simple and convenient, various discharging hoppers and discharging pipes in various industries can be processed, and the problem of chemical material wall adhering more serious than falling coal wall adhering can be solved.

Description

technical field [0001] The invention relates to an anti-bridging and anti-sticking wall device for a silo blanking pipe, which belongs to the field of raw coal supply in thermal power plants, and is also applicable to the field of material transportation such as steel mills, chemical plants, cement plants, coal mines, and wharves. Background technique [0002] Generally, powder or small particle material transportation will use conveying equipment such as silos and drop pipes, which require continuous and stable feeding during operation, especially for high-parameter and large-capacity coal-fired power plants, which require more stable and reliable fuel coal supply. high. However, thermal coal for coal-fired power plants has a wide range of sources and complex and changeable quality, and some raw coal has the remarkable characteristics of high moisture content and high viscosity. In the process of discharging the raw coal bunker, material blockage often occurs, which seriou...
