Description

  The present invention relates to an apparatus for producing pulp from kenaf skin.

  There are various conventional methods for producing pulp from kenaf. The main method is to boil the kenaf with water or water containing sodium bicarbonate and soften it, and then pulverize it with a mixer.

  Since the conventional method of cooking requires several hours of cooking, it takes time to make a pulp. In addition, the work is troublesome because it is not only boiled in a kettle but also pulverized in a mixer. In the method using sodium hydrogen carbonate, the waste liquid becomes pollution.

  The pulp production apparatus of the present invention can easily produce pulp from kenaf skin without using a pressure cooker or sodium bicarbonate.

  In the kenaf pulp manufacturing apparatus of the present invention, two stone mill-shaped grinders are arranged one above the other so that one grinder is fixed and the other grinder can be rotated by a rotary drive, and the upper grinder The tool is vertically penetrated through the supply port that can supply kenaf skin, and the opposing surfaces of both sawing tools are formed in irregularities, and while rotating one of the sawing tools, water flows through the supply port and the kenaf skin is applied. When supplied, the kenaf skin was ground on the opposite sides of the unevenness of both saws and crushed into pulp. In this case, when the lower grinder is rotated and the upper grinder is fixed, it becomes easy to supply the kenaf skin to the supply port, and it is safe without a hand getting caught in the supply port. In addition, the height of one or the other grinder can be adjusted, and the degree of engagement between the grind teeth of both grinders can be adjusted by adjusting the distance between the opposing surfaces of both grinders.

The kenaf pulp production apparatus of the present invention has the following effects.
1. The structure is simple because only two stone mill-shaped grinders are arranged one above the other and only one of them is rotated.
2. By rotating one grinder and supplying kenaf skin to the upper grinder supply port, the kenaf skin is automatically ground and crushed into pulp, so anyone can use it easily. , You can easily make the required amount of pulp.
3. Since the upper and lower sawing tools are housed in the case, the ground kenaf falls into the case and is easy to collect. Further, since the saw tool is accommodated in the case, even if the tool is used, work clothes or the like are not involved and it is safe.
4). If the lower grinder is rotated, the kenaf skin can be supplied to the supply port of the upper grinder that is not rotating. Therefore, it is easy to supply and safe without being caught by hands.
5). By adjusting the height of one or both of the grinders, the degree of engagement of the grind teeth on the opposing surfaces of both grinders can be adjusted, so the ground kenaf skin is made finer or rougher be able to.
6). Since the kenaf skin that has been ground once can be repeatedly ground into the supply port, it can be made into a pulp with the required fineness.
