Description

  The present invention relates to a method and apparatus for crushing and solidifying fine particles, and more particularly to a method and apparatus for improving the safety and crushing and solidification efficiency of a crushing and solidifying device for fine particles containing moisture.

  Of course, rice husks and sawdust having a relatively high water content can be used as they are, but since the use is limited as they are, attempts have been made to use them by crushing or further solidifying them. It was.

  The crushing and solidification is carried out by first supplying crushing materials to a crushing device through a hopper and crushing, and then crushing the crushed material to the next solidification device and heating. Most of them are compressed into continuous solids.

  In such a crushing and solidifying device, frictional heat is generated during crushing, and in a solidifying device, the material is heated to a high temperature for solidification. Therefore, in the crushing device and the solidifying device, water vapor, carbon dioxide gas or the like is generated and filled in the device, and the inside of the crushing and solidifying device is in a high pressure state.

  If the pressure in the crushing and solidifying device rises above a certain level, there is no escape space for water vapor and gases, and an explosion occurs in the device, and the contents are ejected from the exhaust port of the solid material, damaging peripheral equipment and It is very dangerous to hurt. In addition, when such an accident occurs, there is not only such a danger, but the operation of the apparatus must be stopped for a certain period of time.

  If the operation of the apparatus is stopped for a certain period of time, work efficiency will be greatly impaired. Therefore, it is necessary to avoid such an accident as much as possible. In the current apparatus, in order to prevent such an accident, in supplying the crushed material to the hopper, an operator adjusts the supply amount while looking at the state of the apparatus.

  In the present invention, the crushing and solidifying device does not cause the above-mentioned accident, and for this reason, the crushing performance is sufficiently exhibited so that the operator does not need to supply the material to be crushed while adjusting the device. It is an object of the present invention to provide a crushing and solidifying apparatus such as a rice husk and sawdust.

  The invention of claim 1 is a crushing and solidifying device for crushing fine particles containing moisture and then solidifying the crushed material continuously, for discharging water vapor and gases generated inside the device to the outside. It is a fine particle crushing device in which a discharge port is provided adjacent to the supply port of the material to be crushed.

  In the invention of claim 2, the supply means of the material to be crushed is a hopper, and a partition that divides the inside of the hopper in the axial direction into two left and right sections is provided, and one of the two sections is used as a supply port for the material to be crushed, This is a device for crushing and solidifying a fine granule as a discharge port for water vapor and gases in a crushing device having the other open to the outside.

The invention of claim 3 is a pulverizing and solidifying apparatus for fine particles, in which an extending portion extending into a fixed length pulverizing and solidifying apparatus from the hopper lower end opening is provided in the partition means inside the hopper.
In the invention of claim 4, the steam and gas discharge ports of the hopper are provided on the side where the rotary shaft of the crushing and solidifying device rotates from top to bottom, and the supply port for the material to be crushed is the rotary shaft of the crushing and solidifying device. Is a crushed and solidified apparatus for fine particles provided on the side rotating from bottom to top.

The partition means inside the hopper extends into the fixed length crushing and solidifying device from the opening at the lower end of the hopper, so that water vapor and gases can be discharged more effectively.
It is most preferable that the water vapor and gas exhaust ports be provided together with the hopper, but it is not necessarily provided integrally with the hopper.

  The exhaust vent is generated inside the crushing and solidifying device along with the crushing and solidification of the material to be crushed, and accumulated in the crushing and solidifying device to prevent the occurrence of an explosion accident due to an increase in internal pressure. The purpose is to discharge the generated steam and gases to the outside, but the material to be crushed or the material to be crushed must not leak out of the device. And it is preferable to provide in the vicinity of the supply location of the material to be crushed.

Even when the exhaust port for water vapor and gases and the supply port for debris are provided separately, the arrangement is the same as the arrangement when the hopper is divided into two sections when viewed in the axial direction of the crushing and solidifying device. It is preferable.
The scale of the exhaust port varies relatively depending on the scale of the crushing and solidifying device, the processing capacity, the type of the material to be crushed, and for example, it cannot be specified numerically. A quarter or less of the supply port is sufficient.

  According to the present invention, even if a person does not work in accordance with the operation of the apparatus, the explosion does not occur only by the operation of the machine. Therefore, a safe continuous operation without stopping the operation of the apparatus is possible and the efficiency is improved.
