Feeding and guiding method of crusher and guiding device

Abstract

The invention discloses a feeding and guiding method of a crusher and a guiding device. The device comprises a machine shell and a guiding member arranged in the machine shell through a rotating shaft, wherein a guiding plate of the guiding member is located above the rotating shaft; and the guiding plate is arranged in such a way that the guiding surface of the guiding plate supports against a blocking part located near the combined position of a feeding hole and a shell when the side, far away from the guiding surface, of the guiding plate is acted by a rotary gas material flow formed during rotation of a rotor. According to the feeding and guiding method, the guiding surface of the guiding plate supports against the blocking part located near the combined position of the feeding hole and the shell by artfully utilizing an impact force generated by the gas material flow generated by high-speed rotation of the rotor, so that a locking device is omitted to ensure that the structure becomes simple, and meanwhile the sealing performance becomes more reliable. In addition, the guiding plate is matched through automatically carrying out corresponding regulation of the overturning direction along with the change of the rotation direction of the rotor, so that the problem that the rotation direction of the guiding plate needs to pay attention in the using process is avoided, and the direction can be directly changed without stopping.

Description

technical field [0001] The invention relates to an improvement to a hammer mill, in particular to an improvement on a feeding and guiding method and a material guiding device for the pulverizer. Background technique [0002] A general hammer mill includes a feed guide plate 100. The feed guide plate 100 has three main functions. One is to make the material enter the crushing chamber along the tangential direction of the rotor rotation; the other is to prevent the material from forming a crushing chamber. The ring improves the crushing efficiency; the third is to block the material 600 from being thrown to the feeding port by the rotor, causing difficulty in unloading. [0003] Existing feed guide plate 100 all is fixedly connected directly with rotating shaft 200 by its lower side, and the two ends of rotating shaft pass casing 300 and stretch out outside casing; When rotor 400 turns rightward, as figure 1 As shown, the feed guide plate 100 falls to point A on the shell und...

AI Technical Summary

Problems solved by technology

[0005] There are the following problems in the pulverizer with the above-mentioned feed guide plate 100 structure. The one is that the feed guide plate 100 needs to be shut down first when the direction is changed, and then the feed is guided by mechanical or manual methods. It is time-consuming and labor-intensive to reverse the direction of the material plate 100; the second is that the pulverizer will generate a lot of vibration when it rotates at a high speed, which will easily cause the locking device to fail, and the closing performance of the feeding guide plate 100 is poor. The third problem is that due to the closed environment of the crushing chamber, the direction of the feed guide plate 100 cannot be peeped, and whether the feed guide plate 100 is in place after the reversing can not be determined, which may easily cause a coordination error, resulting in the inability to unload the material, thereby affecting the normal work.
